2 to 4, the condom-type drug leak prevention device 100 according to an embodiment of the present invention is provided with a first incision 115 and is installed surrounding the patient's penis. A condom-shaped main body 110 through which a catheter inserted into the urethra penetrates, and located on one inner surface of the main body 110 to be attached to the glans surface around the entrance of the urethra to prevent outflow of drugs into the urethra. It is provided with a second incision 125 and is installed surrounding the glans surface, and includes a gel foam 120 through which the urinary catheter penetrates.

Through this, the condom-type drug leak prevention device 100 can have a double-layer structure in the portion where the gel foam 120 is located. That is, the condom-shaped body 110 serves as an outer layer, and the gel foam 120 serves as an inner layer.

It is desirable that the gel foam 120, which serves as the inner layer, has adhesive strength such that it does not peel off when pushed. It is desirable that the main body 110, which serves as the outer skin layer, is sturdy and has no adhesive force.

The condom-shaped body 110 has a first incision 115 and is installed surrounding the patient's penis, through which a urinary catheter inserted into the patient's urethra can penetrate.

The main body 110 has a condom shape and covers the patient's penis. The condom-shaped body 110 serves as a coating layer for the gel foam 120 and improves convenience of use.

The main body 110 is provided with a first incision 115 so that the drug outflow prevention device 100 can be easily installed on the patient even when a urinary catheter is inserted into the patient's urethra. The first cut portion 115 is a long cut portion from the top of the condom-shaped body 110 to the side. This first incision 115 can be separately fastened using sutures, etc., which will be discussed later.

The main body 110 may be made of at least one of rubber, latex, or urethane, and has excellent elasticity and durability, thereby increasing convenience in installation and use. That is, the main body 110 is made of an elastic material such as rubber, latex, or urethane, which provides a soft feel and room for expansion and contraction of the penis.

Additionally, the main body 110 may be rolled up except for the portion where the gel foam 120 is located before use. This is to prevent damage or damage to the drug outflow prevention device 100 before use and to reduce the size of the drug outflow prevention device 100. In particular, the portion where the gel foam 120 is located maintains its shape, thereby preventing phenomena such as crushing of the gel foam 120.

The gel foam 120 is located on one inner surface of the main body 110 so as to be attached to the glans surface around the entrance of the urethra to prevent the outflow of drugs into the urethra, and is provided with a second incision 125 to prevent the outflow of drugs into the urethra. It is installed surrounding the , and the urinary catheter can pass through it.

The gel foam 120 is applied to the glans area that is sensitive to sensation and pain, thereby maintaining the sealing force due to the characteristics of the gel foam 120 around the urethra entrance, effectively preventing the drug from leaking out of the urethra. In particular, by applying slightly viscous gel foam 120 to the glans surface, pain and discomfort can be reduced and excellent fixation to the external genitalia can be provided.

The gel foam 120 is provided with a second incision 125 so that the drug outflow prevention device 100 can be easily installed on the patient even when a urinary catheter is inserted into the patient's urethra. The second incision 125 is a long incision from the center of the gel foam 120 to the side. The cut surfaces of the second cut portion 125 can adhere to each other through its own adhesive force.

At this time, the cut surfaces of the second cut portion 125 can be attached to each other using a separate adhesive material. The adhesive may be a known medical adhesive that is applied to a wound treatment band or gauze that is in direct contact with the skin and is harmless to the human body. The adhesive material may have been previously applied to the cut surface of the second cut portion 125, but the adhesive material may also be applied directly separately.

Gel foam 120 may be made of silicone. The gel foam (120) is made of a soft silicone gel or hydrogel form to alleviate discomfort when applying the drug leak prevention device (100) and ensures good fixation on the glans surface. Additionally, due to the properties of the gel, it is possible to maintain a high sealing force to prevent the drug from leaking around the urethra where the catheter is inserted.

Referring again to FIG. 4, the gel foam 120 is located around the urethral entrance of the penis (P) where the catheter (C) is inserted, effectively preventing the outflow of drugs into the urethra, and maintaining the drug even when the catheter (C) is inserted. Since the first and second incisions 115 and 125 are formed, the drug leak prevention device 100 is easy to install. Here, after the urinary catheter C is first installed and seated, the condom-type drug outflow prevention device 100 is installed by inserting and fixing it along the cut incision.

The main body 110 and gel foam 120 can be configured additionally for convenience and functionality, which will be discussed later.

Figure 5 is a cross-sectional view of the gel foam of a condom-type drug leak prevention device according to an embodiment of the present invention. In addition, Figure 6 is a view showing a cut portion of the gel foam of a condom-type drug leak prevention device according to an embodiment of the present invention.

Referring to Figure 5, the gel foam 120 preferably increases in thickness toward the entrance of the urethra. As the thickness increases toward the glans, it is possible to more effectively prevent the drug from leaking out of the urethra entrance.

At this time, the thickness of the gel foam 120 may be 1 to 3 mm. That is, the thickness of the gel foam 120 may be 1 mm at its thinnest part and 3 mm at its thickest part. For example, as shown in Figure 5, the gel foam 120 is formed with a thickness of 3 mm from the entrance to the urethra toward the urethra, and has a thickness of 1 mm in the direction perpendicular to the urethra at the part furthest from the entrance to the urethra. Gel foam 120 can be formed.

Referring to FIG. 6, the gel foam 120 may have irregularities 125a formed in contact with each other and attached to the cut surface of the second cut portion 125. The gel foam 120 can be adhered to the second cut portion 125 by the adhesive force of the gel itself.

At this time, the unevenness 125a is formed so that the two cut surfaces of the second cut part 125 correspond to each other, so that the adhesive strength of the two cut surfaces can be further improved. The cross-sectional shape of these irregularities 125a may be formed in various ways, such as square or triangle.

In addition, although not shown in the drawing, an adhesive layer in which a separate adhesive material is applied may be formed on the cut surface of the second cut portion 125. The adhesive material is a harmless ingredient to the human body and may be made of a material different from the gel foam 120.

Figure 7 is a diagram showing an example of a fastening member of a condom-type drug leak prevention device according to an embodiment of the present invention.

Referring to FIG. 7 , the condom-type drug leak prevention device 100 may further include a fastening member 130 connecting the first cut portion 115 of the main body 110. This fastening member 130 is used to prevent the gel foam 120 from falling off through the first cut part 115 of the main body 110. As described above, the gel foam 120 has its own adhesive strength, but the main body 110 does not have adhesive strength, so a separate fastening member 130 is used.

For example, the fastening member 130 may use a suture or tape that connects the two incision surfaces of the first incision 115.

Additionally, as shown in FIG. 7, the fastening member 130 may include a female snap button 132 and a male snap button 131. By using a snap button, the two incision surfaces of the first incision 115 can be simply connected, compared to using sutures or the like. These snap buttons can be made of biodegradable materials that are harmless to the human body.

Figure 8 is a diagram showing an example of a wound coating agent of a condom-type drug leak prevention device according to an embodiment of the present invention.

Referring to FIG. 8, the condom-type drug leak prevention device 100 may further include a wound coating agent 140 located inside the main body 110 except for the portion where the gel foam 120 is located.

After male penile surgery, due to the characteristic shape of the penis, there is the inconvenience of having to cut the covering material to fit the shape of the penis. In order to improve this inconvenience, it is desirable to apply the wound coating agent 140 in advance to the inside of the condom-type drug leak prevention device 100. In particular, the wound dressing 140 is composed of a part that fits the glans surface and a part that fits the penis area below the glans surface and can be mounted inside the condom-type drug outflow prevention device 100.

Through the condom-type drug leak prevention device 100 according to an embodiment of the present invention, the gel foam 120 can be applied to the glans area to prevent drug leakage by maintaining a high sealing force, and the adhesive gel foam 120 ) can be applied to reduce pain and discomfort and achieve excellent external genital fixation effect. In addition, by applying a condom-type drug leak prevention device 100 with a cut portion, it is easy to install and maintain sealing force even when a urinary catheter is inserted.

Although embodiments of the present invention have been described above with reference to the attached drawings, those skilled in the art will understand that the present invention can be implemented in other specific forms without changing its technical idea or essential features. You will be able to understand it. Therefore, the embodiments described above should be understood in all respects as illustrative and not restrictive.
