Description

Probe cover for preventing foreign substance contamination

The present invention relates to a probe cover for preventing contamination by foreign substances.

Ultrasound probes, commonly used in ultrasound imaging diagnostic equipment, are medical devices used to take images of the inside of the human body.

An ultrasound probe like this is composed of a lens that comes into contact with the body of the subject and controls the directionality of ultrasound, a shield that is accommodated inside the lens and removes noise, a matching layer that controls the straightness of ultrasound and acts as an amplifier, a flexible PCB that applies and receives voltage, and a backer that absorbs ultrasound in a specific direction among the ultrasound generated from the ultrasound probe.

Meanwhile, since ultrasound examinations are performed with the ultrasound probe in contact with the subject's body, hygiene management is very important.

Accordingly, during an ultrasound examination, a probe cover is attached to the tip of the ultrasound probe where the lens is placed to perform the examination, and after the examination is completed, the probe cover is removed and the ultrasound probe is disinfected.

At this time, the probe cover attached to the tip of the ultrasonic probe is manufactured in the form of a sheet having an adhesive surface, and a release paper is attached to protect the adhesive surface. Accordingly, the inspector removes the release paper attached to the adhesive surface during inspection and then attaches the probe cover to the tip of the ultrasonic probe for use.

However, conventional probe covers had the following problems:

First, since the release paper is manufactured as a single piece, when the release paper is removed, the adhesive surface is completely exposed to the outside, and as a result, there is a problem that the adhesive surface directly touches the inspector's hand or interferes with and contaminates the surrounding area of the ultrasonic probe during the process of attaching the probe cover to the tip of the ultrasonic probe.

Second, the conventional probe cover was inconvenient to use because it was difficult to remove when attached due to the problems mentioned above, and it was difficult to attach it to the correct location at once.

Third, due to the above-mentioned problems, if the conventional probe cover is not attached to the correct position at once, there is a problem in which an air pocket is formed between the probe cover and the ultrasonic probe, or wrinkles are formed in the probe cover, making it impossible to perform an accurate inspection.

Fourth, there was a problem in that when the conventional probe cover was removed from the ultrasonic probe and then reattached, the adhesive surface became contaminated, making the probe cover unusable and requiring disposal.

Fig. 1 is a drawing showing a probe cover according to an embodiment of the present invention with an ultrasonic probe attached.

Referring to FIG. 1, a probe cover (100) (hereinafter referred to as “probe cover (100)”) for preventing contamination by foreign substances according to an embodiment of the present invention is attached to the head (H) of an ultrasonic probe (P) during an ultrasonic inspection to protect the head (H) from external impact and prevent contamination of the head (H) from foreign substances in the air or foreign substances remaining on other contact objects.

Fig. 2(a) is a plan view showing a probe cover according to an embodiment of the present invention, and Fig. 2(b) is a bottom view showing a probe cover according to an embodiment of the present invention.

Referring to FIG. 1, FIG. 2(a) and FIG. 2(b), the probe cover (100) includes a cover sheet (1) and a release sheet (2).

The cover sheet (1) is attached to the head (H) to protect the head (H).

The cover sheet (1) has an adhesive surface (11) that is attached to the head (H) and a contact surface (12) that comes into contact with the body of the subject. For example, the cover sheet (1) may be formed of a silicone material.

Additionally, the cover sheet (1) includes a first region (S1) and a second region (S2).

The first region (S1) is placed at the center of the cover sheet (1) and is attached to the lens (L) placed at the tip of the head (H) to protect the lens (L).

The second region (S2) extends outside the first region (S1) to surround the head (H) and is attached to the outer surface of the head (H) excluding the lens (L).

The adhesive sheet (2) is attached to the adhesive surface (11) to protect the adhesive surface (11).

The release sheet (2) is separated from the adhesive surface (11) during an ultrasonic inspection, thereby exposing the adhesive surface (11) to the outside. For example, the release sheet (2) may be formed of a paper material. In addition, one surface of the release sheet (2) may be coated to enable the cover sheet (1) to be detached.

The heteromorphic sheet (2) is divided into multiple parts and individually attached to the first region (S1) and the second region (S2).

More specifically, the heteromorphic sheet (2) includes a first heteromorphic portion (21) attached to a first region (S1) and a second heteromorphic portion (22) attached to a second region (S2).

At this time, the first heteromorphic portion (21) is separated from the cover sheet (1) before the second heteromorphic portion (22) during the ultrasound examination, and the second heteromorphic portion (22) is separated from the cover sheet (1) when the first region (S1) is attached to the lens (L).

Therefore, when an ultrasound examination is performed, the examiner first separates the first anomaly (21) from the first region (S1). Then, when the first anomaly (21) is separated, the examiner attaches the first region (S1) to the outer surface of the lens (L) provided on the head (H) of the ultrasonic probe (P). Then, when the first region (S1) is attached to the outer surface of the lens (L), the examiner separates the second anomaly (22) from the second region (S2). Then, when the second anomaly (22) is separated, the examiner attaches the second region (S2) to the outer surface of the head (H) excluding the lens (L).

Meanwhile, the second heterogeneous portion (22) may have a structure divided into multiple parts.

More specifically, the second heterogeneous portion (22) may include a second-first heterogeneous portion (221) attached to a portion of the second region (S2) and a portion of which is exposed to the outside of the cover sheet (1), and a second-second heterogeneous portion (222) attached to another portion of the second region (S2).

Accordingly, during the performance of the ultrasound examination, the 2-1 heteromorphic portion (221) can be separated from the cover sheet (1) when the first region (S1) is attached to the lens (L), and the 2-2 heteromorphic portion (222) can be separated from the cover sheet (1) when a part of the second region (S2) is attached to the outer surface of the head (H).

Fig. 3 is a drawing showing a state in which a phage tab according to an embodiment of the present invention is attached to a cover sheet.

Referring to FIG. 2(a) and FIG. 3, the probe cover (100) may further include a grip tab (3).

The phage tab (3) is attached to the edge of the second area (S2) and is placed between the cover sheet (1) and the second-first part (221), and can be gripped by an inspector when the second-first part (221) is separated.

Through this, the inspector can break the cover sheet (1) without contaminating the adhesive surface (11).

At this time, the phage tab (3) can be detachably connected to the cover sheet (1).

Accordingly, when the second region (S2) is attached to the outer surface of the head (H), the phage tab (3) can be separated from the cover sheet (1).

Fig. 4 is a schematic drawing showing micro air discharge channels according to an embodiment of the present invention.

Referring to FIG. 4, the cover sheet (1) may further include micro air exhaust channels (13).

The micro air exhaust channels (13) can extend radially from the center of the adhesive surface (11) toward the edge of the cover sheet (1).

The micro air exhaust channels (13) can exhaust air remaining between the adhesive surface (11) and the head (H) to the outside when the adhesive surface (11) is attached to the head (H).

Through this, the formation of air pockets due to residual air when attaching the probe cover (100) can be prevented, and the transmission efficiency of ultrasonic waves can be improved by ensuring that the adhesive surface (11) is completely in contact with the head (H).

In addition, the radially extended micro air discharge channels (13) sequentially discharge air from the center of the probe cover (100) to the outside, thereby enabling the probe cover (100) to be uniformly attached to the head (H), thereby improving the inspection quality.

Fig. 5 is a drawing schematically showing a rough pattern according to an embodiment of the present invention.

Referring to FIG. 5, the cover sheet (1) may further include a rough pattern (14).

The uneven pattern (14) is formed in a diamond-shaped grid structure and is placed at the bottom of the contact surface (12) so that a portion thereof may protrude outside the bonding surface (11).

The uneven pattern (14) can be elastically deformed in the horizontal direction when the adhesive surface (11) is attached to the head (H) and is pressed against the head (H).

Through this, the uneven pattern (14) can prevent wrinkles from forming on the contact surface (12) and prevent the cover sheet (1) from being pushed during ultrasonic inspection.

Fig. 6 is a drawing showing an embossed pattern according to an embodiment of the present invention.

Referring to FIG. 6, the probe cover (100) may further include an embossed pattern (4).

The embossed pattern (4) is formed in a square shape and protrudes from the bonding surface (11) and can be placed along the edge of the first region (S1).

The emboss pattern (4) can guide the first region (S1) to be accurately positioned on the lens (L) during the process of attaching the probe cover (100).

In particular, the emboss pattern (4) can prevent the first area (S1) from being spread wider or narrower than the size of the lens (L) by being supported by being caught on the outer surface of the head (H) when the first area (S1) is attached to the outer surface of the lens (L), thereby enabling the first area (S1) to accurately cover the entire outer surface of the lens (L).

The structure of this embossed pattern (4) can improve the accuracy of the attachment position of the probe cover (100) and prevent the occurrence of a gap between the first region (S1) and the lens (L), thereby improving the quality of the ultrasound image.

Fig. 7 is a drawing showing an alignment mark according to an embodiment of the present invention.

Referring to FIG. 7, the probe cover (100) may further include an alignment mark (5).

The alignment mark (5) is formed in a grid structure and can be displayed on the outer surface of the contact surface (12) and placed at a position corresponding to the first area (S1).

More specifically, the alignment mark (5) may include a first identification mark (51) formed in a square shape to indicate the boundary of the first area (S1), second linear identification marks (52) spaced at equal intervals along the Y-axis direction within the first identification mark (51), and third linear identification marks (53) spaced at equal intervals along the X-axis direction within the first identification mark (51).

Accordingly, the inspector can attach the first area (S1) to the outer surface of the lens (L) while aligning the center of the lens (L) exposed to the outside through the first area (S1) with the center of the alignment mark (5).

Fig. 8 is a drawing showing cut grooves and wing fastening parts according to an embodiment of the present invention, and Fig. 9 is a drawing schematically showing the joining structure of the wing fastening parts according to an embodiment of the present invention.

Referring to FIGS. 8 and 9, the probe cover (100) may further include cut grooves (6) and wing fastening portions (7).

The cut grooves (6) are formed at each corner of the second region (S2) to form first cover wings (S21) and second cover wings (S22) that are mutually divided at the edge of the second region (S2).

The first cover wings (S21) may be arranged opposite the edge of the second region (S2) along the longitudinal direction of the cover sheet (1), and the second cover wings (S22) may be arranged opposite the edge of the second region (S2) along the width direction of the cover sheet (1).

The first cover wings (S21) and the second cover wings (S22) can be sequentially attached to the outer surface of the head (H).

At this time, a part of the first cover wings (S21) and a part of the second cover wings (S22) can be arranged to overlap each other.

The wing fasteners (7) can mutually fasten the first cover wings (S21) and the second cover wings (S22) attached to the outer surface of the head (H).

The wing fastening parts (7) may each include catch grooves (71) formed on a portion of the first cover wings (S21) that overlap the second cover wings (S22) when attached to the outer surface of the head (H), and catch protrusions (72) formed on a portion of the second cover wings (S22) that overlap the first cover wings (S21) when attached to the outer surface of the head (H) and supported by being caught on the catch grooves (71).

Fig. 10 is a drawing showing a pollution prevention sheet according to an embodiment of the present invention.

Referring to FIG. 10, the probe cover (100) may further include a contamination prevention sheet (8).

A contamination prevention sheet (8) can be attached to the contact surface (12) to protect the contact surface (12).

That is, the contamination prevention sheet (8) is attached to the contact surface (12) to prevent the contact surface (12) from being contaminated by the external environment during the storage and transportation of the probe cover (100).

In particular, since the contamination prevention sheet (8) is removed immediately before the ultrasound examination, the sanitary condition of the contact surface (12) that comes into contact with the skin of the examinee can be maintained clean.

Through this, concerns about secondary infection can be eliminated, the reliability of ultrasound examination can be improved, and unnecessary disposal of the probe cover (100) due to contamination of the contact surface (12) can be prevented.

Fig. 11 is a drawing showing a real strip according to an embodiment of the present invention.

Referring to FIG. 11, the probe cover (100) may further include a thread strip (9).

The real strip (9) can be attached to the release sheet (2) along the cut portions of the first release portion (21), the second-first release portion (221), and the second-second release portion (222).

Accordingly, the probe cover (100) can support the cut portions of the first heteromorphic portion (21), the second-first heteromorphic portion (221), and the second-second heteromorphic portion (222) to prevent deformation of the cut portions, while blocking the inflow of foreign substances into the cut portions of the first heteromorphic portion (21), the second-first heteromorphic portion (221), and the second-second heteromorphic portion (222).

Meanwhile, although not shown in the drawing, the probe cover (100) may further include a gel sheet (not shown).

The gel sheet is attached to the upper surface of the contact surface (12) of the cover sheet (1) and includes a water-soluble gel that is applied to the contact surface (12) during an ultrasonic examination.

Accordingly, when the cover sheet (1) is pressed while in contact with the skin of the subject for an ultrasound examination, the gel sheet can release the water-soluble gel contained inside.

More specifically, the gel sheet may include a plurality of gel reservoirs filled with a water-soluble gel. The gel reservoirs may be arranged at regular intervals along the surface of the gel sheet, and each gel reservoir may have a capsule structure that bursts when pressurized. This capsule structure may burst in stages according to the contact pressure of the ultrasonic probe (P), sequentially releasing the water-soluble gel.

Additionally, the gel sheet may include a micro-channel pattern to control the release amount of the water-soluble gel.

The micro-Euro pattern connects the gel reservoirs and can guide the water-soluble gel to be uniformly applied across the entire contact surface (12).

The micro-channel pattern can be formed radially to allow the water-soluble gel to spread evenly from the center to the outside.

For example, a hydrophilic coating can be applied to the micro-channel pattern to facilitate the flow of a water-soluble gel.

A remaining amount indicator can be formed on the outer surface of the gel sheet to check the remaining amount of the water-soluble gel.

The remaining amount indicator changes color according to the release of the water-soluble gel, allowing the inspector to intuitively check the remaining amount of gel.

This allows the examiner to replace the probe cover (100) at an appropriate time during the ultrasound examination.

For example, the remaining amount indicator may be formed of a transparent film containing a pH-sensitive pigment, so that the remaining amount of the gel can change from blue to colorless when the remaining amount of the gel is below a set amount.

Additionally, the gel sheet may include a protective layer to prevent evaporation of the water-soluble gel.

A protective layer is formed on the outermost side of the gel sheet to improve the storage stability of the water-soluble gel.

The protective layer is removed immediately prior to ultrasonic examination, and a protrusion for phagocytes may be formed on one side to facilitate removal.

For example, the protective layer may be formed of an aluminum deposition film and may include a semicircular protrusion for phagnum moss.

Additionally, the gel sheet may include an expiration date indicator to indicate when it should be used.

The expiration date indicator may gradually change color over time to indicate whether the water-soluble gel is ready for use.

This ensures that the inspector always uses the optimal water-soluble gel.

Such gel sheets can improve the efficiency of examination by eliminating the need for a separate gel application process during ultrasound examination, and can also optimize the amount of gel used to increase cost-effectiveness.

In this way, according to the embodiment of the present invention, the release sheet (2) has a structure in which it is sequentially separated by dividing into a first release portion (21), a second-first release portion (221), and a second-second release portion (222), so that the adhesive surface (11) is not exposed all at once, thereby preventing the adhesive surface (11) from being contaminated.

In addition, the present invention has a part of the 2-1 heteromorphic portion (221) exposed to the outside of the heteromorphic sheet (2) and a grip tab (3) provided, so that the inspector can easily grip and attach the probe cover (100).

In addition, since the adhesive surface (11) of the present invention is gradually exposed and attached, it is possible to prevent air pockets or wrinkles from forming between the probe cover (100) and the ultrasonic probe (P), thereby enabling accurate ultrasonic inspection.

In addition, the present invention enables precise positional attachment of the probe cover (100) due to the split structure of the heteromorphic sheet (2) and the phage tab (3), thereby preventing unnecessary disposal of the probe cover (100) and shortening the inspection time, thereby improving inspection efficiency.
