Description

Test catheter

The present invention relates to an apparatus for sterile urine test, urethral hypermotility test of urinary incontinence patient, test for endogenous sphincter dysfunction and vaginal-urinary fistula test and the like.

In modern society, the medical interest is increasing as the elderly and the economic level are improved. In particular, the frequency of cystitis and urinary incontinence due to difficulty urinating is increasing year by year, resulting in physical and mental pain and economic burden on individuals, families and society. Therefore, early diagnosis and consequent early treatment can reduce the burden on individuals and society by advancing the time of cure. In particular, there is a growing interest in the treatment of urinary incontinence, which can occur frequently in middle-aged or older women. Urinary incontinence means that the bladder and the urinary tract loses control due to the loss of control, regardless of one's will. Due to such incontinence, many women are inconvenient in social life, as well as causing the shame or discomfort caused by the complicated treatment procedure in the treatment of urinary incontinence.

In patients with urinary tract symptoms, the most basic test is a sterile urine test. Sterile urine tests generally use a device called a ellaton catheter, which is approximately 32 cm in length and flexible, making it difficult to insert into the urethra, as well as difficulty in urinating and urine. Unexpected frying due to unexpected discomfort, possibly resulting in aseptic flaws.

 In addition, one of the important factors that determine the prognosis of surgical treatment of urinary incontinence is the hypermotility of the urethra. A so-called Q-tip test is a method of diagnosing over-motility of the urethra with ultrasound diagnosis. In the case of ultrasound diagnosis, expensive equipment is used, and there is a burden on the test fee, but Q-tip test is widely used because it provides a lot of help in determining the postoperative prognosis as well as low test cost and high diagnostic value. The commonly used Q-tip test uses a wooden swab, which always causes the pain or the possibility of causing urethral inflammation due to the resistance of the cotton swab at the tip of the swab, the strength of the wood, and the fine grain of wood. There is a problem.

In addition, the conventional Nellaton catheter cannot be used for Q-tip testing because of its long length and flexibility. Therefore, if both a sterile urine test and a Q-tip test are required, the urine test must be performed again with a wooden swab after the urine test with a ellaton catheter. In this process, the urethra may be damaged, and there is a problem of causing shame in female patients.

In such a case, since the meaning is clearly described in the detailed description of the part, it should not be interpreted simply by the name of the term used in the description of the present invention, and it should be understood that the meaning of the term should be interpreted. .

First, the first evaluation method for a patient suffering from urinary incontinence includes a history test, a physical examination, an evaluation of residual urination after urination, and a urination diary. The physical test includes a urine test, a Q-tip test, a urethral cystoscopy, and a urethra dynamic test. Among them, the Q-tip test is widely used as the simplest and most economical method for evaluating the hypermotility of the urethra.

A Q-tip test involves applying jelly to a sterilized Q-tip and inserting it into the urethra so that one end of the swab is in the bladder neck, then the patient passes the valsalva maneuver (mouth). It is a test to measure the changed angle of a cotton swab by covering the nose and exhaling and exhaling) or coughing. At this time, by measuring the changed angle of the cotton swab is determined to be positive if more than a certain angle (for example, 30 degrees), which means the support damage and over-mobility of the bladder urethral boundary. As such, the Q-tip test is the simplest and most economical way to assess the degree of relaxation of the urethra and bladder neck, and plays an important role in the diagnosis and evaluation of tension incontinence and in planning treatment.

In addition to the Q-tip test, aseptic factors such as sterile urine test, vaginal-urinary fistula test, and endogenous sphincter dysfunction test may be used as other factors that determine the prognosis of surgical treatment of urinary incontinence. Here, sterile urine testing generally means inserting a device called a ellaton catheter into the bladder and testing the urine collected therefrom. The vaginal-urinary fistula test means a test for checking whether the dye is discharged through the vagina when the dye is diluted and injected into the bladder through the urethra. If the dye is released through the vagina, it means that a fistula was formed between the vagina and the bladder or between the vagina and the ureter. In addition, the endogenous sphincter dysfunction test is a state in which the desorption prevention portion is formed when a catheter is inserted into the bladder through the urethra and a desorption prevention portion such as a balloon is formed by injecting some liquid or gas into the distal end of the catheter. This means that the catheter is pulled out of the chamber to observe whether there is resistance by the sphincter at the bladder entrance. At this time, if the catheter can be removed without resistance, it means that there is endogenous sphincter failure.

As such, when performing a sterile urine test, a vaginal-urinary fistula test and an endogenous sphincter dysfunction test together with the Q-tip test, a more accurate and efficient urinary incontinence diagnosis and treatment plan can be made.

Accordingly, the present invention provides a test catheter capable of performing the various tests described above. Hereinafter, various embodiments of the test catheter will be described in detail.

1 is an embodiment to which the present invention is applied and is shown to explain an embodiment of an inspection catheter having various inspection functions.

Referring to FIG. 1, the test catheter 100 to which the present invention is applied may include a flow path part 110, a support part 120, a first opening part 130, and a second opening part 140.

First, the flow path part 110 forms a flow path of liquid introduced through one end or the other end of the test catheter 100. For example, when one end of the test catheter 100 is inserted into the bladder through the urethra and the other end is exposed to the outside of the body, the liquid inside the bladder is introduced through the one end, and the introduced liquid is The flow path is formed through the flow path unit 110. The flow path part 110 may have an appropriate shape to smoothly flow the introduced liquid. For example, as shown in FIG. 1, the flow path part 110 may have an elongated cylindrical shape, but the present invention is not limited thereto.

The support 120 serves to transmit a predetermined force. For example, the support part 120 may be used to measure the angle of the urethra changed by abdominal pressure while one end of the test catheter 100 is inserted into the bladder. The support 120 may have a suitable shape to transmit a predetermined force. For example, as shown in FIG. 1, the support part 120 may have a shape of an elongated tube that is hollow, but the present invention is not limited thereto. In addition, the empty interior of the support 120 may form the flow path 110 for the flow of liquid, one end of the support 120 is formed to have a predetermined curvature for flexible insertion into the body. Can be.

On the other hand, the support 120 may have the following features to deliver a predetermined force.

First, the support 120 may be inflexible in order to transmit a predetermined force. As used herein, inflexible means a property that an object is not bent and not bent, and, for example, may mean a property that one end and the other end of the support part 120 may maintain a horizontal state when no force is applied from the outside. Can be. Alternatively, the inflexibility may mean the hardness or strength of the object, and may include, for example, at least one of bending strength, compressive strength, tensile strength, shear strength, and acupressure strength. As an embodiment of the present invention, the support 120 may be formed to have a predetermined inflexibility for convenience of insertion and adjustment in the body. For example, it may be formed to have a predetermined inflexibility that can be inserted into the urethra with one hand. Alternatively, the support part 120 may be formed to have a degree of inflexibility such that a Q-tip test may be possible.

In one embodiment, the support 120 may be formed of various components such that one end and the other end of the support 120 has a non-flexibility to maintain a horizontal state. For example, the support part 120 may be formed of metal, plastic, rubber, or the like, but the present invention is not limited thereto. As a specific example, when the support part 120 is formed of a metal component, the support part 120 may be formed to have a minimum inflexibility that can be leveled for flexible insertion into the body. Alternatively, one end and the other end of the support part 120 may be formed of a cured rubber to have a non-flexibility to maintain a horizontal state.

In another embodiment, the support part 120 may have a separate support member (eg, a metal wire, a synthetic resin wire, or a plastic) so that one end and the other end of the support part 120 may be inflexible. Element wires); For example, by including a metal element wire between the outer surface and the inner surface of the support portion 120, one end and the other end of the support portion 120 can be made inflexible to maintain a horizontal state.

In another embodiment, the support 120 has a non-flexibility to maintain only a portion of the support 120 in a horizontal state, the rest may have a flexible flexibility. Here, the flexibility may refer to a property in which the horizontal state cannot be maintained even when no force is applied from the outside. For example, a portion where the force does not need to be transmitted, that is, one end of the support 120 that is present in the bladder when one end of the support 120 is inserted into the bladder (eg, D in FIG. 5 (2)). Portion) or the other end portion of the support portion 120 exposed to the outside of the body (for example, the left end portion of B of FIG. 5 (2)) does not necessarily have to be inflexible to maintain a horizontal state.

On the other hand, the support 120 may include an opening for outflow of liquid or gas. For example, the opening part may be located at at least one of one end and the other end of the support part 120. Referring to FIG. 1, a first opening 130 is formed at one end of the support 120, and a second opening 140 is formed at the other end of the support 120. In this case, the first opening 130 may be formed in a predetermined size on the circumferential surface of the support 120 for a flexible insertion into the body or a smooth flow of the liquid. The second opening 140 may be formed at the other end of the other end to smoothly discharge the liquid introduced into the first opening 130.

The first opening portion 130 and the second opening portion 140 serve to flow in or out of the liquid or gas in the body (or injected from the outside of the body), at least one of one end and the other end of the support portion 120 It can be located somewhere. For example, when one end of the support part 120 is inserted into the body, the liquid in the body is introduced through the first opening 130, and the introduced liquid is introduced into the body through the flow path part 110. The liquid is delivered to the opening 140 and the liquid flows out of the human body through the second opening 140. On the contrary, when liquid is injected from the outside through the second opening 140, the liquid may be introduced into the body through the first opening 130.

In addition, the present invention by providing a test catheter having a convenient length to adjust, not only can be inserted into the body more conveniently, but also can conveniently receive the urine discharged through the second opening 140 in the container. For example, although the urethra length of an adult woman may vary from person to person, since it is usually 3 to 4 cm, it may be provided in a length longer than that of an adult woman. In addition, the length of the conventional ellaton catheter for urine discharge is about 32cm long, which is not only inconvenient for the operator to insert into the patient's urethra, but also inconvenient to control the ellaton catheter, causing the swelling to occur. do. Accordingly, the present invention provides a test catheter longer than the length of the urethra and shorter than the length of the existing ellaton catheter, which is convenient for insertion into the urethra of the patient and convenient for adjustment for urine collection.

In addition, the present invention can perform various tests with one insertion into the body. For example, by inserting a test catheter to which the present invention is applied into the bladder of a patient once, at least one of aseptic urine test, Q-tip test, vaginal-urinary fistula test and endogenous sphincter dysfunction test can be performed. . In this case, the endogenous sphincter dysfunction test may be performed by a preventive unit (described in FIG. 10) to be described later. For example, an aseptic urine test may be performed by first inserting a test catheter to which the present invention is applied into the patient's bladder and then draining the urine. After the urine is drained, a dye can be injected in that state to perform vaginal-urinary fistula examination. Then, the patient can perform a Q-tip test by measuring the angle at which the test catheter is moved by causing the patient to cough or cough, and finally, by forming a prevention part to prevent detachment or insertion of the test catheter. Endogenous sphincter dysfunction testing may be performed. This is merely an example, and the operator may optionally perform at least one of the above tests using the present invention as needed.

This saves the discomfort and hassle of having to insert different tools into the urethra each time for aseptic urine tests, Q-tip tests, vaginal-urinary fistula tests, and endogenous sphincter failure tests. You can reduce the pain and shame caused by inserting other tools into your device. In addition, frequent insertion of other tools into the urethra may cause inflammation of the urethra or infection by other bacteria. In particular, when using a wooden material, such as cotton swabs may cause side effects and urinary tract infection, etc. In the present invention, by using a flexible material harmless to the human body can be completely eliminated the side effects. In addition, since only one insertion can be performed by selecting only necessary tests among the above tests, a very efficient test can be performed.

The features described above may be applicable in all embodiments to which the present invention is applied, as well as in FIG.

2 to 4 illustrate another embodiment to which the present invention is applied to explain another embodiment of the test catheter.

2 to 4 are further characterized in that the control unit 250, 350, 450 that can control whether the liquid flows in and out of the invention of FIG. Therefore, all of the features of FIG. 1 may be applied, and hereinafter, the features of the control units 250, 350, and 450 will be described with emphasis.

Referring to FIG. 2, the inspection catheter 200 of FIG. 2 to which the present invention is applied includes a flow path part 210, a support part 220, a first opening part 230, a second opening part 240, and an adjusting part ( 250). The adjusting part 250 may be composed of a handle part 251, a coupling part 252 and a connection part 253.

The adjuster 250 serves to discharge the liquid through one end of the support 220 or to block the outflow of the liquid, and may be provided in a form detachable or coupled from one end of the support 220. For example, the adjusting part 250 is connected to the first opening portion 230 and the string form 253 at one end of the support portion 220 to be freely coupled to or separated from the first opening portion 230. May be possible. When the control unit 250 is coupled to the first opening 230, the liquid may be prevented from flowing out of the first opening 230. Alternatively, when the adjusting part 250 is separated from the first opening part 230, the liquid may flow out of the first opening part 230. Thus, by having a structure that can freely couple or separate the control unit 250 and the support 220, the operator can adjust the appropriate time, discharge, and the like of the discharge and storage of the liquid, and also whether the discharge of urine in the bladder Regardless of which Q-tip test can be performed.

In the embodiment of FIG. 2, the control part 250 is connected to the support part 220 and the connection part 253, so that the control part 250 can be easily managed in the coupling or separation thereof. In this case, the connection portion 253 may be provided in the form of a string, it may be made of a flexible material to move freely. Alternatively, the connection part 253 may be provided in a fixed form for convenience of management when combining or separating.

In addition, the handle part 251 is positioned at one end of the adjusting part 250 to separate the adjusting part 250 from the supporting part 220 or the supporting part 220 and the adjusting part 250. It serves as a handle to combine. The handle part 251 may be provided in various forms. For example, in FIG. 2, the handle part 251 has a flat cylindrical shape, but the present invention is not limited thereto. Or it may be provided in the form of a groove, etc. on the circumferential surface of the handle portion 251 for convenience of adjustment, such as separation, removal or coupling.

The coupling part 252 may have the same shape as the inner cross section of the first opening part 230 to block the outflow of the liquid from the first opening part 230. For example, in FIG. 2, the coupling part 252 has a flat cylindrical shape, and a circular surface on one side thereof is in contact with one surface of the handle part 251. In addition, the diameter of the circular surface of the coupling portion 252 has a diameter equal to or greater than the inner diameter of the first opening portion 230 to prevent liquid from being discharged from the first opening portion 230. Can be.

Similarly, the coupling portion 252 may have a shape corresponding to the inner cross section of the first opening portion 230 as shown in FIG. 2, but the present invention is not limited thereto. The shape of the coupling part 252 may vary depending on the internal shape of the support part 220. For example, if the inner cross-section of the support 220 is not a round tube but a square tube or a rhombus tube, the coupling portion 252 may have the same shape. Alternatively, in some cases, the shape of the coupling part 252 may have a shape different from that of the support part 220. For example, even if the inner shape of the support part 220 is a square shape, the shape of the coupling part 252 may have a circular shape. This is because the material of the support part 220 may be stretched to allow the coupling part to have a circular shape. As long as the 252 is inserted, the inner shape of the support 220 may be deformed into a circular shape.

3 to 4, only the features of the adjusting units 350 and 450 will be described.

The adjuster 350 is capable of being separated from and coupled to the supporter similarly to the adjuster 250 of FIG. 2. The function of the control unit 350 performs a function similar to the control unit 250 of FIG. However, in the present embodiment, the adjusting part 350 may be provided separately without being connected to the support part. Therefore, when the Q-tip test is performed after urine discharge, the Q-tip test can be performed without considering the weight of the control unit 350 by separating the control unit 350. Alternatively, the Q-tip test may be performed considering only the weight of the support. In addition, the handle part 351 and the coupling part 352 may apply the features of the handle part 251 and the coupling part 252 described with reference to FIG. 2.

In another embodiment of the present invention, referring to FIG. 4, the adjusting part 450 may be configured of a handle part 451 and a coupling part 452.

For example, when a portion of the first opening portion 751 is inserted into the body, the liquid in the body flows into the first opening portion 751, and the introduced liquid passes through the flow path portion 752. The liquid may be delivered to the opening 753, and eventually the liquid may flow out of the human body through the second opening 753. Alternatively, when the external liquid flows through the second opening 753, the liquid may flow into the body through the first opening 751.

The inspection means 710 may be used for Q-tip inspection. For example, the distal end portion 731 of the inspection means 710 is inserted through the second opening portion 753 of the flow-out means 750, and a part of the adjustment portion 720 is the second opening portion ( When it is in close contact with the 753, the inspection means 710 and the flow-in and out means 750 may be combined into a single tool. By inserting the combined test catheter 700 into the urethra of the patient once, at least one of a sterile urine test, a Q-tip test, a vaginal-urinary fistula test, and an endogenous sphincter dysfunction test may be performed.

The adjustment unit 720 may be composed of a handle portion 721 and the coupling portion 722. The controller 720 may be applied to various features of the controller described with reference to FIGS. 2 to 6. Similarly, the handle part 721 and the coupling part 722 may also have various features of the handle part and the coupling part described with reference to FIGS. 2 to 6.

On the other hand, the support portion 730 is in the shape of a long elongated rod, one end is in contact with the coupling portion 722, the other end portion 731 is formed round and inclined for flexible insertion into the flow-out means 750 Can be. The support part 730 may be formed of metal, plastic, rubber, or the like. In addition, other features of the support 730 may be applied to the features of the support described in Figures 1 to 6 above.

In another embodiment (not shown), the support portion 730 may be in the shape of an elongated tube to smoothly flow the liquid into the inflow and out means 750, or may be in the form of at least one perforated tube. have. In addition, a hole may be formed in the distal end portion 731 which is the other end of the support portion 730 to facilitate the flow of the liquid. In other words, the support 730 may be provided in any form as long as it can maintain a predetermined inflexibility. Here, the predetermined non-flexibility means the degree to which one end and the other end of the support part 730 can maintain a horizontal state, and the features described with reference to FIG. 1 may be applied.

In addition, the support part 730 may be formed to a length such that the distal end portion 731 of the inspection means 710 can enter the bladder. The length of the support part 730 may be applied to the feature of the length described in FIG.

8, another embodiment of the inspection means is shown. In FIG. 8 (1), the inspection means 810 may include a support part 830 and an adjusting part 820. The adjusting unit 820 may be composed of a handle portion 821 and the coupling portion 822. The adjusting part 820 may be an integral member of the support part 830 or a separate member, and in the case of a separate member, the adjusting part 820 may be coupled to or separated from each other. Features of the supporter described with reference to FIGS. 1 to 7 may be applied to the support part 830 and the adjustment part 820.

When the adjuster 820 is a separate member from the supporter 830, the adjuster 820 may have a hole at the center thereof so as to be coupled to the supporter 830 having a rod shape. FIG. 8 (2) is a cross-sectional view taken along line 8-8 'of FIG. 8 (1) and shows a case in which a hole is formed in the center of the adjusting unit 820.

As such, when the adjusting part 820 and the support part 830 can be combined or separated from each other as an integral or separate member, the support part 830 is not only a support means for Q-tip inspection but also a liquid in the human body. It can also serve as a control unit to block the discharge. For example, when the support part 830 is inserted through the hole of the control part 820 in a state in which the control part 820 is combined with the flow-out means 750, the liquid in the human body is discharged out. It becomes possible to prevent it. In this state, the Q-tip test may be performed.

In addition, when the control unit 820 is separated from the control unit 820 in a state in which the control unit 820 is coupled with the flow-out means 750, the control unit 820 is located within the human body through the central hole of the control unit 820. The liquid will be drained out. Alternatively, even when the control unit 820 is separated from the inflow and outflow means 750, the liquid in the human body can be discharged out.

FIG. 9 illustrates an embodiment to which the present invention is applied and illustrates a method of performing Q-tip test and urine discharge using the test catheter described with reference to FIGS. 1 to 8.

Referring to FIG. 9, (1) shows a state in which the test catheter to which the present invention is applied is inserted into the bladder through the urethra, and (2) shows a state in which the test catheter is moved during the Q-tip test. In FIG. 9 (1) and (2), the support part 930 and the support part 931 may exist together, but as shown in the embodiments of FIGS. 1 to 6, only the support part 930 exists without the support part 931. Can be. Alternatively, an inspection catheter including the support 931 may be provided as in the embodiment of FIGS. 7 to 8. In this case, the inflexibility of the support part 930 or the support part 931 has been described with reference to FIGS. 1 to 8.

First, the test catheter is inserted into the bladder through the urethra so that the opening 910 can be located in the bladder. In this case, the urine introduced through the opening part 910 may be retained in the support part 930. In this state, Q-tip inspection can be performed. A patient may be asked to perform a Q-tip test by measuring the angle (θ) the catheter was moved by, for example, by using a valsalva maneuver (blocking mouth and nose and exhaling) or coughing. For example, when the Q-tip test is performed by using the test catheter to which the present invention is applied, it is determined whether the bladder urethral boundary part is damaged or not, and whether or not over mobility. Here, the constant angle means an angle that can be determined by a predetermined experiment or statistics, and for example, 30 degrees may be a reference.

The constant angle may vary depending on experimental conditions. For example, the constant angle may mean an angle determined by an experiment or statistics using a test catheter to which the present invention is applied.

As a specific example, the constant angle may vary according to the weight of at least one of the support part 930 or 931 and the adjusting part 920. Alternatively, the predetermined angle may vary depending on at least one material (component) of the support part 930 or 931 and the adjusting part 920. In addition, the constant angle may vary depending on the length of at least one of the support part 930 or 931 and the adjusting part 920. In addition, the predetermined angle may vary depending on the hardness of the support 930 or 931.

For example, in FIG. 9, when the Q-tip test is performed while retaining urine in the support 930, an angle equal to or smaller than 30 degrees may be a reference. Alternatively, when only the support part 930 is used or the support part 931 is used in a combined form, since the weight may be heavier than a conventional catheter, the constant angle may be equal to or less than 30 degrees. have. Alternatively, when the support part 930 or the support part 931 is made of a light material and its weight is lighter than that of a conventional catheter, the constant angle may be equal to or greater than 30 degrees. Alternatively, even when the support part 930 or the support part 931 has a length of a predetermined level or more, the predetermined angle may be an angle equal to or smaller than 30 degrees. Here, the length or more than a certain level may mean the length determined by the experiment or statistics.

The Q-tip test can be performed by measuring the angle at which the test catheter moves outside the human body. That is, it is possible to determine whether the damage to the bladder urethral border portion support and whether or not over mobility.

FIG. 10 is an embodiment to which the present invention is applied and is shown to explain an extended function from the test catheter described with reference to FIGS. 1 to 8.

Referring to FIG. 10, the test catheter 1000 to which the present invention is applied includes a first prevention part 1010, a first injection part 1020, and a second prevention part 1030 and a second injection part 1040. It may include at least one. That is, the test catheter 1000 may include only the first prevention part 1010 and the first injection part 1020, or may include only the second prevention part 1030 and the second injection part 1040. Alternatively, the first prevention part 1010 and the first injection part 1020, and the second prevention part 1030 and the second injection part 1040 may be included.

The first prevention part 1010 and the second prevention part 1030 shown in FIG. 10 are inflated like a balloon by injecting liquid or gas, if necessary, after the test catheter is inserted into the human body. That is, when the test catheter 1000 to which the present invention is applied is inserted into the bladder, the first prevention part 1010 and the second prevention part 1030 may not protrude out of the surface of the support part 1050. have.

The first prevention part 1010 serves to prevent the test catheter from naturally falling out after being inserted into the bladder. Or, in some cases, when artificially attempting to remove the test catheter, it may serve as a weak grip so as not to fall easily. The first prevention portion 1010 may be made as part of the test catheter. In addition, the first prevention portion 1010 may not be protruded at all times and may be made to protrude as necessary. For example, the case of Foley catheter can be mentioned. Foley catheter is a device for inserting into the bladder of the patient to discharge urine, a device that can inflate one end of the catheter like a balloon to attract the catheter inside the bladder for a certain time. For example, the first prevention part 1010 may be inflated like a balloon by injecting liquid or gas through the first injection part 1020. When the first prevention portion 1010 acts as a clasp in the bladder, the endogenous sphincter dysfunction test can be performed by observing whether there is resistance by the sphincter at the entrance of the bladder while pulling out the test catheter 1000.

The second prevention unit 1030 may serve to prevent the test catheter from being inserted into the human body. The second preventive portion 1030 may also be made as part of the test catheter, like the first preventive portion 1010. Or it may be made so that it may protrude as needed rather than always protruding. Similarly, the second prevention part 1030 may be inflated like a balloon by injecting liquid or gas through the second injection part 1040.

The inspection catheter 1000 to which the present invention is applied may optionally include the first prevention part 1010 or the second prevention part 1030. For example, the test catheter 1000 may include only the first prevention part 1010, or may include only the second prevention part 1030. Alternatively, the first prevention part 1010 and the second prevention part 1030 may be included or both may not be included. 10 illustrates a state in which both the first and second prevention portions 1010 and 1030 are inflated after the test catheter 1000 is inserted into the bladder.

In addition, an identifier indicating the length may be displayed on an outer surface of the test catheter to which the present invention described with reference to FIGS. 1 to 8 is applied. For example, the identifier indicating the length may be indicated by a scale, a number, a color, or a material. In addition, an identifier capable of representing the length may be displayed from one end of the insertion of the test catheter. Or from one end exposed to the exterior of the test catheter.

As a specific example, by marking the scale on the outer surface of the test catheter, it is possible to confirm how much of the device is inserted into the actual bladder and urethra, and to determine how much to insert. The urethra length of an adult woman may vary from person to person, but is usually similar to 3-4 cm. Therefore, when the test catheter is inserted deep into the urethra and the bladder and hits the bladder wall, it may not only damage the bladder wall but also cause discomfort to the patient. In addition, if the test catheter is excessively inserted into the bladder and is twisted, it may cause fatal damage to the patient, and urine discharge may not be smooth. As such, it is important to recognize how much to insert the test catheter.

Therefore, in the present invention, the insertion length of the test catheter or the length exposed to the outside can be confirmed by displaying an identifier indicating the length on the outer surface of the test catheter.

In addition, since the test catheter to which the present invention described in FIGS. 1 to 8 is applied has a predetermined non-flexibility while being formed of a flexible material, the target of the body can be quickly and accurately without injuring blood vessel walls when inserted into the body. Until the test catheter can be reached. For example, when insertion or withdrawal of the catheter into the bladder or the like, the position can be adjusted by the operator. In addition, by providing a portion to be inserted into the bladder in a round shape it can be inserted without damaging the urethra. The outer diameter of the test catheter can be made as small as possible to reduce the frictional resistance with the urethral wall. In order to increase the inner diameter in order to suppress the flow resistance of the material in the urethra, the inner layer of the test catheter may be formed very thin. For example, a fluororesin can be used as a constituent material of the inner layer, and in particular, a tetrafluoroethylene polymer (PTFE) excellent in chemical resistance, low friction, and electrical insulation can be used.

The embodiments described above are just one embodiment, and the present invention is not limited thereto. Various features of the embodiments described with reference to FIGS. 1 to 10 may be combined with each other. In addition, the embodiments of the present invention described above are disclosed for the purpose of illustration, those skilled in the art within the spirit and scope of the present invention disclosed in the appended claims, improvements, modifications, and various other embodiments Replacement or addition may be possible.
