Description

Drug leakage prevention device {DRUG OUTFLOW PREVENTING DEVICE}

The present invention relates to a device for preventing drug leakage attached to the male external genitalia.

Urethral stenosis is a symptom of discomfort caused by narrowing of the urethra due to scars and the like in the process of healing wounds on the mucous membrane of the urethra due to inflammation or injury.

1 is a view for explaining urethral stenosis.

Referring to FIG. 1, strictures (S) occur inside the urethra (U) of the patient's penis (P), so that the inside of the urethra is narrowed. In the case of patients with urethral stricture, surgery is performed to widen the narrowed urethra mainly with an endoscope.

On the other hand, the biggest problem of treatment for urethral stenosis is that the recurrence rate due to fibrosis after surgery reaches 50 to 70%. Therefore, various expensive drugs for preventing stenosis are used to suppress recurrence due to restenosis after surgery.

By the way, the drug administration method for preventing the recurrence of stenosis is using a primitive method of administering the drug to the side of the catheter and tying gauze to the catheter to prevent leakage to the outside of the body.

Therefore, in order to treat urethral stenosis, expensive drugs must be repeatedly administered several times. Accordingly, waste of expensive drugs may occur. In addition, there is a problem in that the patient must not move for a day by fixing the urinary catheter to the abdomen so that the drug in the urethra does not leak out of the body, and the patient's discomfort occurs due to the primitive method of tying gauze to the urinary catheter.

2 is a perspective view of a condom-type drug leakage prevention device according to an embodiment of the present invention. In addition, Figure 3 is a cross-sectional view of a condom-type drug spill prevention device according to an embodiment of the present invention viewed from the top. And, Figure 4 is a view showing a state in which a condom-type drug leakage prevention mechanism according to an embodiment of the present invention is used.

2 to 4, the condom-type drug leakage prevention device 100 according to an embodiment of the present invention is provided with a first incision 115 and installed while surrounding the patient's penis, A condom-shaped main body 110 through which a urinary catheter inserted into the urethra passes, and 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 leakage of the drug into the urethra. It has a second incision 125, is installed while surrounding the glans surface, and includes a gel foam 120 through which the urinary catheter passes.

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

It is preferable that the gel foam 120 serving as the inner skin layer has adhesive strength to the extent that it is not pushed and peeled off. The main body 110 serving as the outer skin layer is preferably rigid and non-adhesive.

The condom-shaped body 110 has a first incision 115 and is installed while surrounding the patient's penis, and a catheter inserted into the patient's urethra can pass therethrough.

The main body 110 has a condom shape and covers the patient's penis. The condom-shaped main body 110 becomes a coating layer of the gel foam 120 and allows to increase the convenience of use.

The main body 110 includes a first incision 115 so that the device 100 for preventing drug leakage can be easily installed on the patient even when the catheter is inserted into the patient's urethra. The first cutout 115 is a part that is long cut from the apex of the condom-shaped body 110 to the side. The first incision 115 may be separately fastened using a suture or the like, which will be described 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, since the main body 110 is formed of an elastic material such as rubber, latex, or urethane, it has a soft feel and leeway during expansion and contraction of the penis.

In addition, the main body 110 may be rolled except for a portion where the gel foam 120 is located before use. This is to prevent the drug leakage prevention mechanism 100 from being damaged or damaged before use and to reduce the size of the drug leakage prevention mechanism 100 . In particular, by maintaining the shape of the portion where the gel foam 120 is located, it is possible to prevent the gel foam 120 from being crushed.

The gel foam 120 is located on the inner surface of one side of the body 110 so as to be attached to the glans surface around the entrance of the urethra in order to prevent the outflow of the drug into the urethra, and has a second incision 125 to the glans surface. It is installed while surrounding, and the catheter can pass through.

The gel foam 120 is applied to the glans area, which is sensitive to sensation and pain, to effectively prevent the drug from leaking out of the urethra by maintaining a sealing force due to the characteristics of the gel foam 120 around the entrance of the urethra. In particular, by applying the slightly viscous gel foam 120 to the glans surface, it is possible to reduce pain and discomfort and to provide excellent fixing power to the external genitalia.

The gel foam 120 has a second incision 125 so that the drug leakage prevention device 100 can be easily installed on the patient even when the catheter is inserted into the patient's urethra. The second incision 125 is a part that is long incised from the central part of the gel foam 120 to the side. The cut surfaces of the second cutout 125 may adhere to each other by their own adhesive force.

At this time, the cut surfaces of the second cut portions 125 may be attached to each other using a separate adhesive material. As the adhesive material, a known medical adhesive material applied to a wound treatment band or gauze that directly contacts the skin harmless to the human body may be used. The adhesive material may be previously applied to the cut surface of the second cutout 125, but the adhesive material may be separately applied directly.

Gel foam 120 may be made of silicone. The gel foam 120 is made in the form of a soft silicone gel or hydrogel so that it is well fixed to the glans surface while relieving discomfort when the drug leakage prevention device 100 is applied. In addition, due to the characteristics of the gel, it is possible to maintain a high sealing force so that the drug does not leak around the urethra where the catheter is inserted.

Referring back to FIG. 4, the gel foam 120 is positioned around the urethra entrance of the penis P where the urinary catheter C is inserted to effectively prevent the outflow of the drug into the urethra, and even when the urinary catheter C is inserted, Since the first and second incisions 115 and 125 are formed, the drug leakage prevention mechanism 100 is easy to install. Here, after the urinary catheter (C) is first installed and seated, the condom-type drug leakage prevention device 100 is inserted and fixed along the cut incision.

The main body 110 and the gel foam 120 may have additional configurations for convenience and functionality, which will be described later.

5 is a view showing a cross-section of a gel foam of a condom-type drug leakage prevention device according to an embodiment of the present invention. 6 is a view showing an incision of a gel foam of a condom-type drug leakage prevention device according to an embodiment of the present invention.

Referring to Figure 5, it is preferable that the gel foam 120 increases in thickness toward the inlet side of the urethra. As the thickness increases toward the glans portion, 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 formed to 1 ~ 3mm. That is, the thickness of the gel foam 120 may be 1 mm at the thinnest part and 3 mm at the thickest part. For example, as shown in Figure 5, the gel foam 120 is formed in a thickness of 3mm from the entrance of the urethra to the side of the urethra, and has a thickness of 1mm in the direction perpendicular to the urethra at the farthest part from the entrance of the urethra. As a gel foam 120 may be formed.

Referring to FIG. 6 , the gel foam 120 may have irregularities 125a attached to the incision surface of the second incision 125 in contact with each other. The gel foam 120 may be adhered to the second cutout 125 by the adhesive strength of the gel itself.

In this case, since the unevenness 125a is formed so that the two cut surfaces of the second cut portion 125 correspond to each other, the adhesive strength of the two cut surfaces may be further improved. The cross-sectional shape of the irregularities 125a may be variously formed, such as a square or a triangle.

In addition, although not shown in the drawings, an adhesive layer coated with a separate adhesive material may be formed on the cut surface of the second cutout 125 . The adhesive material is a component harmless to the human body and may be formed of a material different from that of the gel foam 120.

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

Referring to FIG. 7 , the condom-type drug spill prevention device 100 may further include a fastening member 130 connecting the first cutout 115 of the main body 110 . The fastening member 130 is to prevent the gel foam 120 from falling through the first cutout 115 of the main body 110 . As described above, the gel foam 120 has its own adhesive strength, but the body 110 has no adhesive strength, so a separate fastening member 130 is used.

For example, the fastening member 130 may use a suture or tape connecting two cut surfaces of the first cut portion 115 .

In addition, as shown in FIG. 7 , the fastening member 130 may include a female snap button 132 and a male snap button 131 . Compared to the case of using a suture or the like by using a snap button, it is possible to simply connect the two cut surfaces of the first cut portion 115 . These snap buttons may use biodegradable materials that are harmless to the human body.

8 is a view showing an example of a wound dressing of a condom-type drug leakage prevention device according to an embodiment of the present invention.

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

After male penis surgery, due to the characteristic shape of the penis, it is inconvenient to cut and use the covering material according to the shape of the penis. In order to improve this inconvenience, it is preferable to apply and use the wound dressing 140 in advance to the inside of the condom-type drug leakage prevention device 100. In particular, the wound dressing 140 may be installed inside the condom-type drug spill prevention device 100, consisting of a part that fits the glans surface and a part that fits the penis below the glans surface.

Through the condom-type drug leakage prevention device 100 according to an embodiment of the present invention, the gel foam 120 is applied to the glans area to prevent the leakage of the drug through maintaining a high sealing force, and the gel foam 120 with adhesive strength ) can be applied to reduce pain and discomfort, as well as obtain an excellent external fixation effect. In addition, by applying the condom-type drug leakage prevention device 100 having an incised portion, it is possible to maintain sealing force while facilitating installation even in a state where a catheter is inserted.

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