Description

Technical Field

[0001] This utility model relates to a urine catheter that prevents urine leakage, and belongs to the field of urine catheter technology. Background Technology

[0002] A urinary catheter is a tube inserted into the bladder through the urethra to drain urine. It is made of natural rubber, silicone rubber, or polyvinyl chloride (PVC) and can be inserted into the bladder through the urethra to drain urine. After the urinary catheter is inserted into the bladder, a balloon near the tip of the catheter secures the catheter in the bladder and prevents it from easily falling out. The drainage tube is connected to a urine bag to collect urine.

[0003] Chinese Patent Publication No. (CN 210542829 U) discloses a urine-preventing catheter, comprising a catheter body, a water channel, a second channel, and a third channel. A water valve is connected to the top of one side of the catheter body. A balloon is connected to the outer surface of the catheter body. A guide hole is opened on the inner side of the balloon, located inside the catheter body. The water channel is located inside the catheter body and the water channel. A catheter waist is provided on one side of the balloon. A first side hole is opened on the outer surface of the catheter waist. A second side hole is opened on the end surface of the catheter body. By designing and installing the catheter waist and the first side hole on the surface of the catheter body, urine can easily leak through the narrow cavity between the catheter and the urethra when the patient's abdominal pressure increases. By utilizing the fact that the minimum outer diameter of the catheter waist is smaller than the maximum outer diameter of the catheter body, urine can be drained into a urine bag through the catheter waist and the first side hole, effectively preventing urine from leaking out of the body. The aforementioned device mainly uses the expansion of a single balloon to seal the patient's urethra, thereby preventing urine from leaking out through the outside of the catheter. However, in actual use, different areas of the urethra vary in size, and a single balloon may not be able to completely fit the patient's urethra, which may still lead to leakage and urine seepage, affecting the operator's normal use.

[0004] Therefore, a urine-preventing catheter is proposed. Utility Model Content

[0005] In view of this, the present invention provides a urine catheter that prevents urine leakage, so as to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0006] The technical solution of this utility model is implemented as follows: a urine-proof catheter includes a catheter body, a catheter groove is provided at the top of the catheter body, and grooves are provided around the perimeter of the catheter body surface. A urine-proof component is provided on the surface of the catheter body, the urine-proof component includes a first water balloon and a second water balloon. The first water balloon is fixedly installed at the top of the catheter body surface. A first cavity is provided on the inner surface of the catheter body, and a first inlet tube is fixedly installed in the inner cavity of the first cavity. The first inlet tube communicates with the inner cavity of the first water balloon. The second water balloon is fixedly installed at the middle of the catheter body surface. A second cavity is provided on the inner surface of the catheter body, and a second inlet tube is fixedly installed in the inner cavity of the second cavity. The second inlet tube communicates with the inner cavity of the second water balloon.

[0007] More preferably, the first water bladder and the second water bladder are made of the same material, and the first water bladder and the second water bladder are made of medical-grade silicone.

[0008] More preferably, the first water bladder and the second water bladder are both in the same vertical direction, and the size of the second water bladder is larger than the size of the first water bladder.

[0009] More preferably, the first inlet pipe and the second inlet pipe have the same inner cavity size, and both the first inlet pipe and the second inlet pipe are connected to an external liquid supply device.

[0010] More preferably, the slots are arranged equidistantly in the circumferential direction, and the inner cavity of the slot is connected to the inner cavity of the leak-proof component.

[0011] More preferably, the catheter body is connected to an external fluid collection device, and the catheter body is made of polyurethane.

[0012] The present invention has the following advantages due to the adoption of the above technical solution: I. This utility model, by setting up a urine leakage prevention component, expands the first water balloon through the first inlet tube, thereby sealing the slightly narrow part of the patient's urethra. The second water balloon expands through the second inlet tube, thereby sealing the slightly wider part of the patient's urethra. Compared with single sealing, the double sealing can effectively reduce the leakage of urine due to incomplete sealing, ensuring the stability of patient use and facilitating operation for operators.

[0013] Second, by setting up a first water-filled bladder and a second water-filled bladder, the characteristics of the materials of both can prevent damage to the urethra when it is blocked. By setting up a catheter body, the characteristics of its material can prevent damage to the urethra when it is inserted into the urethra and left in place for a long time.

[0018] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0019] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0020] Example 1 like Figure 1-5As shown, this utility model embodiment provides a urine-preventing catheter, including a catheter body 1, a catheter groove 3 at the top of the catheter body 1, and grooves 4 on all four sides of the surface of the catheter body 1. A urine-preventing component 2 is provided on the surface of the catheter body 1, including a first water bladder 201 and a second water bladder 202. The first water bladder 201 is fixedly installed at the top of the surface of the catheter body 1. A first cavity 205 is formed on the inner surface of the catheter body 1, and a first inlet pipe 203 is fixedly installed in the inner cavity of the first cavity 205, communicating with the inner cavity of the first water bladder 201. The second water bladder 202 is fixedly installed at the middle of the surface of the catheter body 1. A second cavity 206 is formed on the inner surface of the catheter body 1, and a second inlet pipe 204 is fixedly installed in the inner cavity of the second cavity 206, communicating with the inner cavity of the second water bladder 202.

[0021] By setting up the anti-leakage component 2, the first water balloon 201 expands through the liquid supply from the first inlet pipe 203, thereby sealing the slightly narrower part of the patient's urethra. The second water balloon 202 expands through the liquid supply from the second inlet pipe 204, thereby sealing the slightly wider part of the patient's urethra. Compared with single sealing, the double sealing can effectively reduce the leakage of urine due to incomplete sealing, ensuring the stability of patient use and making it convenient for operators to use.

[0022] Example 2 like Figure 2-5 As shown, in one embodiment, the first water bladder 201 and the second water bladder 202 are made of the same material, and the first water bladder 201 and the second water bladder 202 are made of medical silicone. The first water bladder 201 and the second water bladder 202 are both in the same vertical direction. The size of the second water bladder 202 is larger than the size of the first water bladder 201. The inner cavity size of the first inlet tube 203 and the second inlet tube 204 is the same. The first inlet tube 203 and the second inlet tube 204 are both connected to the external liquid supply device. The slots 4 are all equidistantly arranged in the circumferential direction. The inner cavity of the slot 4 is connected to the inner cavity of the anti-leakage component 2. The catheter body 1 is connected to the external liquid collection device. The material of the catheter body 1 is polyurethane.

[0023] By setting up the first water bladder 201 and the second water bladder 202, the characteristics of their materials can prevent damage to the urethra when it is blocked. By setting up the catheter body 1, the characteristics of its material can prevent damage to the urethra when it is inserted into the urethra and left in place for a long time.

[0024] When this invention is in operation: the entire device is inserted into the patient's urethra. Then, through an external liquid supply device, water is injected into the inner cavity of the first water bladder 201 via the first inlet pipe 203. At this time, the first water bladder 201 expands due to the water injection, thus sealing the slightly narrower part of the urethra. Subsequently, water is injected into the inner cavity of the second water bladder 202 via the second inlet pipe 204. The second water bladder 202 expands due to the water injection, thus sealing the slightly wider part of the urethra, completing the work of preventing urine leakage from the patient's urethra. The patient's urine enters the inner cavity of the slot 4 and the catheterization groove 3 through the urethra, and then is discharged through the catheterization groove 3, completing the urine discharge work.

[0025] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
