Description

Integrated blood transfusion structure with visible light irradiation

The present invention provides an integrated blood transfusion tube structure with visible light irradiation that has simple structure, low manufacturing cost, can be illuminated simultaneously during blood transfusion, and has the advantages of high conditioning efficiency, high inspection accuracy, and high safety and hygiene.

According to the medical field, blood analysis is often required, including analysis of blood drawn from the human body and analysis before blood is transfused back into the human body. Such blood analysis can be used to examine blood samples (such as the number of red blood cells, hemoglobin concentration, and other blood components or types), blood type identification, or blood disease detection, etc. The application range is quite wide, and the above medical procedures from blood drawing, testing, analysis to blood transfusion take 4 to 5 hours, and the whole process is very physically demanding and mentally exhausting.

It is known that during the blood drawing or transfusion process, a laser light emitter is added to the outside of the blood transfusion tube to test and analyze the blood at the same time during the transfusion process. Different power and wavelength of the light can even produce different positive effects on the blood, such as increasing the oxygen content of red blood cells and controlling the number of white blood cells. However, although this optical system can effectively shorten the waiting time required for the inspection process and produce positive effects on the blood, because the laser light is irradiated from the outside of the blood transfusion tube, it is easy to cause inaccurate test results or difficult to control light parameters. The main reason is that in order to avoid being affected by the ambient temperature, the blood transfusion tube usually has a certain thickness, so when the light penetrates, it is easy to produce deviation errors due to the refraction of the light, or produce light attenuation due to penetrating the thicker blood transfusion tube.

In addition, for example, the Republic of China Patent Announcement No. M617339 "Blood Transfusion Intravenous Monitoring Warning and Blood Quality Promotion Device" uses a shell to be positioned on the intravenous tube of the blood transfusion bag, and the light emitter in the shell emits monitoring light to the blood. This technology has the above-mentioned problem of inaccurate test results. At the same time, because the shell is attached to the intravenous tube, it must be a reusable device. Although it will not be directly contaminated with blood during the operation process, in the medical field, any blood-related equipment will have the risk of infection as long as it is reused.

Therefore, how to solve the above-mentioned problems and deficiencies in usage is the direction that the applicant of this invention and related manufacturers engaged in this industry are eager to study and improve.

Therefore, in view of the above-mentioned deficiencies, the applicant of this invention has collected relevant information, evaluated and considered various aspects, and used the years of experience accumulated in this industry, through continuous trials and modifications, to design this kind of simple structure, low manufacturing cost, and can be illuminated at the same time during blood transfusion, and has the advantages of high conditioning efficiency, high inspection accuracy, and high safety and hygiene. The patent holder of the invention of the integrated structure of the blood transfusion tube with visible light irradiation.

The main purpose of the present invention is to select a bonding colloid with a higher melting point, and simultaneously heat-melt and solidify the first colloid of the blood transfusion tube and the second colloid of the light tube to form an integrated structure. This can control costs and also take into account health and safety through disposable use.

Another main purpose of the present invention is to combine the light tube with one side of the blood transfusion tube, with an integrated structure, so that the emitted visible light waves can directly illuminate the blood, thereby improving the conditioning efficiency and inspection accuracy.

To achieve the above-mentioned purpose, the main structure of the present invention includes: a blood transfusion tube, a first colloid, a blood supply end, a bleeding end, a blood transfusion section, a light tube, a second colloid, a light emitting device, and a combined colloid. The blood transfusion tube is used to transmit blood. The first colloid is located in the blood transfusion tube. The blood supply end is defined at one end of the blood transfusion tube. The bleeding end is defined at the other end of the blood transfusion tube away from the blood supply end. The blood transfusion section is defined between the blood supply end and the bleeding end, the light tube is combined with the blood transfusion section and connected with it, the second colloid is located in the light tube, the light emitting device is located on the side of the light tube away from the blood transfusion section to emit visible light waves and directly irradiate the blood through the light tube, and the combined colloid is located between the blood transfusion tube and the light tube, and its melting point is greater than the first colloid and the second colloid.

When the user uses the present invention to help patients with blood transfusion, since the blood transfusion section of the blood transfusion tube is connected to a light tube, when the blood supply end flows the blood through the blood transfusion section to the bleeding end, the light-emitting device on one side of the light tube will emit visible light waves to irradiate the blood. In this way, the blood can be treated simultaneously during the blood transfusion process to shorten the entire blood transfusion time. Moreover, since the light tube is connected to the blood transfusion section, the visible light waves are directly irradiated on the blood without penetrating the blood transfusion tube, so the conditioning efficiency and the accuracy of the test can be improved. In particular, the combination of the blood transfusion tube and the light tube uses a bonding colloid with a higher melting point, and is simultaneously hot-melted and solidified with the first colloid and the second colloid to form an integrated structure. Therefore, the combination cost is low, and it is a structure designed for disposable use, which further improves health safety.

The above technology can be used to overcome the problems of the conventional blood transfusion drip monitoring warning and blood quality promotion devices, such as the light needs to penetrate the blood transfusion tube, resulting in low accuracy of the test results or poor conditioning effect, and the equipment allows or requires repeated use, which poses a risk of infection, and achieve the practical progress of the above advantages.

In order to achieve the above-mentioned purpose and effect, the technical means and structure adopted by the present invention are described in detail in the following figure for the preferred embodiment of the present invention, and its features and functions are explained for complete understanding.

Please refer to the first to third figures, which are three-dimensional perspective diagrams to usage status diagrams of the preferred embodiments of the present invention. It can be clearly seen from the figures that the present invention includes:

A blood transfusion tube 1, used for blood transfusion;

A first colloid 11 is located in the blood transfusion tube 1;

A blood supply end 12 is defined at one end of the blood transfusion tube 1;

A bleeding end 13 is defined at the other end of the blood transfusion tube 1 away from the blood supply end 12;

A blood transfusion section 14 is defined between the blood supply end 12 and the bleeding end 13;

A light-carrying tube 2 is coupled to the blood transfusion section 14 and is connected thereto;

A second colloid 21 is located inside the light tube 2;

A light emitting device 3 is disposed on the side of the light tube 2 away from the blood transfusion section 14 to emit visible light waves and directly illuminate the blood through the light tube 2; and

A bonding colloid 4 is disposed between the blood transfer tube 1 and the light tube 2, and its melting point is greater than that of the first colloid 11 and the second colloid 21, so as to be heat-melted simultaneously with the first colloid 11 and the second colloid 21, and to form an integrated structure after solidification.

In addition, the blood supply end 12 is connected to a blood transfusion device 5, which is one of a blood transfusion bag, a hemodialyzer, or a blood purification device. This embodiment takes a blood transfusion bag as an example.

The first colloid 11 is polypropylene (PP); the second colloid 21 is polymethyl methacrylate (PMMA), the difference between the melting point of the first colloid 11 and the melting point of the second colloid 21 is less than or equal to 10 degrees; the bonding colloid 4 is polystyrene (PS), and this embodiment is implemented with high heat-resistant polystyrene (HIPS); the wavelength of the visible light wave is 360nm~830nm. However, the corresponding types of the above-mentioned components are only examples of preferred embodiments. All types with the same function belong to the scope of the present invention and are not limited to the above-mentioned examples.

Through the above description, the structure of the present technology can be understood. According to the corresponding coordination of this structure, the structure can be simple, the manufacturing cost can be low, and the light can be irradiated at the same time during blood transfusion. It has the advantages of high inspection efficiency, high accuracy, and high safety and hygiene. It can be clearly seen from the figure that when the user uses the present invention to help the patient with blood transfusion, the blood in the blood transfusion device 5 will not only flow from the blood supply end 12, the blood transfusion section 14, and the bleeding end 13 to the user's body, but because the blood transfusion section 14 of the blood transfusion blood vessel 1 is connected to a light tube 2, when the blood flows through the blood transfusion section 14, the light emitting device 3 on one side of the light tube 2 will emit visible light waves to irradiate the blood. In this way, the blood transfusion process can be completed at once. The blood transfusion action, blood test action or blood conditioning action can be completed to shorten the entire blood transfusion process. Because the light tube 2 is connected to the blood transfusion section 14, the visible light wave is directly irradiated on the blood without penetrating the blood transfusion tube 1, so the conditioning effect and the test accuracy can be improved. The conditioning effect is based on the different power and wavelength of the light, and different spectra are used to stimulate the biochemical reaction of the human blood, so that the molecular energy of the protein in the blood changes, and can achieve such as increasing the oxygen content of red blood cells, repairing surface damage, improving membrane deformation ability, improving blood circulation, controlling the number of white blood cells, enhancing immune regulation and phagocytosis, reducing platelet aggregation in blood vessels, reducing blood viscosity, changing blood flow, etc.

In particular, the combination of the blood transfusion tube 1 and the light tube 2 uses a bonding colloid 4 with a relatively high melting point, which is simultaneously hot-melted and solidified with the first colloid 11 and the second colloid 21 to form an integrated structure. Specifically, the first colloid 11 made of polypropylene colloid (PP) has a normal operating temperature range of approximately 0°C to 100°C and a melting point of approximately 160°C to 166°C. The second colloid 21 made of polymethyl methacrylate (PMMA) has a normal operating temperature range of approximately -40°C to 80°C and a melting point of approximately 160°C to 165°C. The difference in melting point between the two is less than 10 degrees, and they can basically be regarded as melting at the same time. The bonding colloid made of high heat-resistant polystyrene (HIPS) has a normal operating temperature range of approximately -40°C to 80°C and a melting point of approximately 160°C to 165°C. The normal operating temperature range of the gel 4 is approximately -20℃ to 70℃, and the melting point is approximately between 200℃ and 220℃. Therefore, when heated, as long as the bonding gel 4 melts, it can be ensured that the first gel 11 and the second gel 21 have also melted. The first gel 11, the second gel 21 and the bonding gel 4, which are all in a fluid state, are combined into one at this time, and after re-cooling and solidification, the blood transfusion tube 1 and the light tube 2 become an integrated structure in an integrated state. This combination method only increases the material cost of the bonding gel 4, so the overall structure cost is relatively low. As a disposable design, it does not increase too much cost burden. On the contrary, because the disposable design can eliminate the problem of blood infection, it greatly improves health safety.

Please refer to the fourth and fifth figures at the same time, which are schematic diagrams of implementation and detection of another preferred embodiment of the present invention. It can be clearly seen from the figures that the present embodiment is similar to the above-mentioned embodiment, except that the blood transfusion device 5 is changed into a hemodialyzer, and the hemodialyzer has a display screen 51, and the blood transfusion tube 1 is provided with a spectrum detection element 6 on the side of the blood transfusion section 14 away from the light emitting device 3. The spectrum detection element 6 can be a photodiode, a photodiode array, a photomultiplier tube, a CCD (Charge-Coupled Device) Device) or other types of light detectors, the spectrum detection element 6 can sense light of different wavelengths, convert light energy into electrical signals, and convert it into absorption spectrum data 61 through a signal processing system. Therefore, it is set on one side of the blood transfusion tube 1, so that the visible light waves of the light emitting device 3 pass through the blood, pass through the blood transfusion tube 1 and are absorbed. Since the light waves have passed through the blood, the absorption action of the light waves has been completed, and no error will be generated when passing through the blood transfusion tube 1 again, or it can be simply eliminated, and it can be convenient to use. The absorption spectrum data 61 collected by the spectrum detection element 6 is then transmitted to other data analysis software or instruments (such as the blood transfusion device 5) for analysis. In this embodiment, the absorption spectrum data 61 can be displayed on the display screen 51. The display result is briefly illustrated in the fifth figure. The blood transfusion device 5 is used to analyze the absorption spectrum, and the background is the absorption spectrum graph of visible light. The waveform diagram of the corresponding wavelength can be generated through conversion operations, where the Y axis is the absorption spectrum and the X axis is the wavelength.

In addition, the light emitting device 3 may have a housing 31, a control substrate 32 disposed in the housing 31, a switch element 33 disposed on the housing 31 and electrically connected to the control substrate 32, and a warning element 34 electrically connected to the control substrate 32. The switch element 33 may be one of a button, a lever, or a knob, and the warning element 34 may be one of a speaker or an LED. In this way, after the light-emitting device 3 is powered on, the user can transmit the start signal, shutdown signal, or brightness adjustment signal generated when operating the switch element 33 to the control substrate 32, and the control substrate 32 drives the LED or laser generator of the light-emitting device 3 to start, and the control substrate 32 simultaneously transmits the signal to the warning element 34 to remind the user whether the light-emitting device 3 is currently in the on state or the off state. In this way, the user can ensure that the light-emitting device 3 is turned on only when the blood transfusion action is performed, which not only saves electricity, but also prevents the laser light from irradiating the human body or other places.

Therefore, all simple modifications and equivalent structural changes made by using the contents of the present invention's specification and drawings should be included in the patent scope of the present invention and should be stated.
