Description

Urine catheter with stopper

The present invention relates to a catheter for discharging urine with a stopper, and more specifically, at the end of the catheter, which is expressed outside the human body, a pipe inlet for injecting a balloon inflation solution or washing water is formed by extending in the axial direction of the urine discharge tube. The catheter has a constant cross section so that surgical or therapeutic gauze or instrument can be easily replaced, and the axially extending tube inlet is formed with an ellipse to block the urine discharge tube without a separate plug. It relates to a catheter for urine drainage is provided with a stopper.

In general, the catheter is a device that allows access to surgical tools by injecting into the body cavity, urethra or blood vessels, or discharges fluid to the outside or injects drugs into the surgical site.

The urinary catheter, a component of the catheter, is used to insert urine into the bladder along the urethra to inject drugs into the bladder or to discharge urine from the bladder to the outside to relieve severe urine stagnation caused by prostate hypertrophy. If it is impossible to put the catheter through the urethra (urethral constriction or urethral infection) or if a catheter is inserted for long-term urination, urine is released into the bladder through the upper pubis rather than through the urethra.

Attach the gauze or instrument to the part that inserts the catheter communicated to the bladder into the human body to prevent the catheter insertion part from infecting or absorbing a small amount of fluid flowing out of the body to prevent other parts from being contaminated and strengthening hygiene by periodic replacement I'm making it.

However, at the end of the catheter, the balloon-expansion liquid injection tube and / or the washing water injection tube branch from the urine discharge tube, which is the main body, to the side to form two lines or three lines. Since the separated multiple tube is located side by side with the urine discharge tube, the coaxial cross section of the catheter is finally expanded, and the expanded catheter cross section is difficult to pass through the hole in the center of the gauze or instrument attached to the human body. Therefore, cutting and removing the gauze or the instrument and then attaching a new gauze or instrument or replacing the catheter, there is a significant inconvenience and economic loss.

In addition, the catheter wearer has to be attached to the inside or outside of the urine collector in order to perform the external activities, it is cumbersome, and for simplicity to remove the urine collector can be equipped with only the catheter, but urine is discharged through the urine discharge pipe of the catheter There is a hassle that needs to be prevented by using a separate stopper to prevent this. In particular, a catheter stopper that is stored separately requires hygienic storage to prevent infection with bacteria, which was very inconvenient to use.

In some catheter, there is provided a form in which the stopper is integrally formed at the end of the catheter, but this also increases the cost of the catheter and increases the cost of the catheter. There is a disadvantage that mounting is more cumbersome.

However, the present invention is not limited to the embodiments described herein and may be embodied in other forms. Rather, it is provided to ensure that the contents introduced herein are thorough and complete, and that the spirit of the present invention to those skilled in the art can fully convey.

1 is a perspective view showing a catheter for urine discharge according to the present invention, Figure 2 is an enlarged partial cross-sectional view showing the end of the catheter formed balloon portion.

As described above, the urine discharge catheter 10 according to the present invention includes a urine discharge tube 20 which is a main tube body for discharging urine, and a balloon-expansion liquid injection tube 30 in which the urine discharge tube extends in an axial direction from an end thereof. It is configured by.

The urine discharge tube 20 is a tubular body formed long in the longitudinal direction, one end of the insertion end 21 is inserted into the bladder, the other end of the discharge end 22 is expressed to the outside of the body to the urine in the bladder introduced from the insertion end Discharge to the outside through the outlet 25 of the discharge end.

The insertion end 21 is formed with an inlet 23 for introducing urine in the bladder, and an inner receiving space 241 is formed along the circumferential surface of the side wall adjacent to the inlet so that an expansion solution (distilled water) is supplied to the urine discharge tube. Part of the inlet 23 of the urine discharge tube insertion end portion 21 is formed in the bladder by expanding the balloon portion after the insertion into the bladder to expand the balloon portion to the bladder inner wall after insertion into the bladder. The removal can be prevented. As a means for injecting a balloon expansion liquid (distilled water) into the balloon portion 24, the inner receiving space 241 in the balloon portion is connected to the surface of the discharge end 22 of the urine discharge tube within the side wall of the urine discharge tube 20. It is made through the expansion liquid injection passage 26 formed to be.

In addition, a balloon-expansion liquid injection tube 30 is further formed on the surface of the distal end portion 22 of the urine discharge tube to extend the expansion liquid injection passage 26 in the axial direction of the urine discharge tube. The balloon-expansion liquid injection pipe 30 is formed of a tubular body extending in the length of 4 ~ 8cm, preferably 5cm in the axial direction from the urine discharge pipe outlet end 22.

As shown in FIG. 3, the balloon-expansion liquid injection pipe 30 may have a fan-shaped cross section to increase an internal flow path area. That is, since the side wall thickness of the urine discharge tube 20 is thin, in order to provide a sufficient flow path area, the expansion is performed in the end surface of the side wall of the urine discharge tube. In this case, the expansion fluid injection passage 26 formed in the urine discharge pipe 20 may also be expanded in a fan shape to have the same cross-sectional area as the internal flow path of the balloon expansion fluid injection pipe 30.

In addition, the end of the balloon expansion liquid injection pipe 30 may be expanded to facilitate the coupling with the balloon expansion liquid injector so that the coupling site is formed, the expansion pipe for forming the coupling site is the expansion range of the urine discharge pipe It takes place within.

As shown in Figure 4a and 4b the end of the balloon expansion liquid injection pipe 30 of the present invention may be further formed with a stopper 50 to be fitted to the outlet 25 of the urine discharge pipe. The stopper 50 is formed by expanding the balloon-expansion infusion tube, formed in the shape of a cone as shown in the protruding portion to block the outlet 25 of the urine discharge tube, or formed in an elliptical protruding portion of both sides of the stopper Either site can block the outlet of the urine drainage tube. At this time, the protruding portion of the stopper 50 may be formed to a length of approximately 1.5 ~ 3cm to gradually fit the outlet 25 of the urine discharge pipe by gradually narrowing the cross-sectional width.

In addition, the stopper 50 may form an injection hole of the balloon expansion fluid injection tube at the protruding end or side, and preferably, when the stopper 50 is mounted at the discharge port of the urine discharge tube, the inside of the urine discharge tube 20 is formed. The injection hole 31 is formed on the side surface which is not inserted to prevent the urine from being introduced into the balloon inflation tube and contaminated. In addition, when the plug is elliptical, the inlet is formed in the center portion can be prevented from being inserted into the outlet of the urine discharge tube. The balloon expansion liquid injection pipe 30 is inserted into the inlet through the individual plug after the expansion of the balloon portion 24 is made to close or prevent the discharge of the injected expansion liquid is reversed by installing a check valve In addition, the plug material is formed of a soft material so that the injection hole is normally closed by material characteristics, and when the expansion liquid is injected, a method of inserting an injection means such as a needle into the injection hole may be applied.

On the other hand, the catheter 10 of the present invention may be formed in a manner in which the three water bodies are connected to the washing water injection pipe 40 is further formed.

At this time, the washing water injection pipe 40 may be connected to the connection portion 41 is connected to the washing water injection device by extending the end of the washing water injection pipe in the range within the cross-sectional area of the urine discharge pipe.

In addition, since the balloon-expansion liquid injection tube 30 and the washing water injection tube 40 extend in the axial direction at the distal end of the urine discharge pipe 20, at one end of the tube of the balloon-expansion liquid injection tube and the washing water injection tube. The stopper 50 may be formed to block the outlet 25 of the urine discharge tube.

In addition, the extended lengths of the balloon-expansion liquid injection pipe 30 and the washing water injection pipe 40 are formed to be different from each other, even if the end of each injection pipe is expanded (same section cut in the direction orthogonal to the axis). Because it is not located in the catheter, the catheter may not extend beyond the axial section of the urinary drainage tube. For example, if the balloon expansion liquid injection pipe 30 is extended by 5cm, the washing water injection pipe 40 is extended to different lengths such as to extend to 3cm.

The balloon-expansion liquid injection pipe 30 and the washing water injection pipe 40 may be extended in the axial direction from the spaced apart portions facing each other at the distal end surface of the urine discharge pipe 20, to prevent each tube from tangling, The washing water injection pipe may also be formed into a tubular body having a fan-shaped cross-section similar to the balloon expansion liquid injection pipe, thereby expanding the internal flow path cross section within a limited range.

In addition, the expansion liquid injection passage 26 and the washing water injection passage 27 formed in the urine discharge pipe 20 are formed in a fan-shaped cross-section, or secured a flow path by inserting additional tubular body therein, the portion extending to the outside Alternatively, the extended portion can be extended or expanded to a fan-shaped cross section without additional tube. In the present invention, the expansion liquid injection passage 26 and the washing water injection passage 27 include securing a passage by inserting a separate pipe body therein, and the fan-shaped cross section is an expanded portion of the balloon expansion liquid injection tube or the washing water injection tube. It can be formed only, it can be expanded in the form of a cone between the urine discharge tube inner passage and the fan-shaped cross section of the extended portion so that the entire passage can be connected.

The catheter 10 having the structure as described above may be coated with an antimicrobial material on the inner surface of the stopper 50 and the inner side of the urine discharge tube 20 fitted with a stopper to minimize contamination. The antimicrobial material may be coated using a known material that is harmless to the human body. The coating range of the inner surface of the urine discharge tube may be made of 3 ~ 5cm range from the outlet to prevent internal contamination by the stopper coupling stored outside.

In addition, as shown in Figure 6, the cone-shaped or elliptical stopper 50 may be disinfected when not in use by installing a disinfection member 60. The disinfecting member 60 is composed of a main body container 61 of which one side is opened, and an absorbent layer 62 in which the disinfecting solution placed inside the main body container is impregnated. The disinfecting member 60 is inserted into the disinfecting member inserted into the urine discharge tube 20 of the catheter of the unused stopper 50 while the stopper surface is disinfected by the disinfecting solution in the absorbent layer 62 of the disinfecting member. It is coated with disinfectant solution so that it can be managed hygienically at all times.

In addition, in the case of an oval stopper can be mounted to both sides that can be inserted into the urine discharge tube of the catheter, or can be used only mounted on one side. In this case, when the disinfection member is mounted only on one side, the disinfecting member may be used when the disinfecting member is inserted into the urine discharge tube, and the disinfecting member may be mounted on another portion which is not inserted into the urine discharge tube.

As shown in Figure 7a and 7b according to another embodiment of the catheter 10, the balloon expansion liquid injection pipe 30 and the washing water injection pipe 40 is the discharge end surface of the urine discharge pipe 20 side wall ( It is possible to extend in the axial direction of the urine discharge tube 20 while being disposed close to one side of 22). That is, the expansion liquid injection passage 26 and the washing water injection passage 27 are proximately formed on the side wall of the urine discharge tube, from which the balloon expansion liquid injection tube 30 and the washing water injection tube 40 are integrally coaxial with the urine discharge tube. To extend.

The extending balloon expansion liquid injection pipe 30 and the washing water injection pipe 40 has a length different from each other by extending a predetermined length by having a different length, the pipe is separated from each other, the connection portion for connecting with other devices at the end of the separated pipe ( 41 or a stopper 50 is formed. In FIG. 7A, a connection part 41 is formed at the end of the washing water injection pipe 40 and a stopper 50 is formed at the end of the balloon expansion liquid injection pipe 30 to block the discharge port of the urine discharge pipe. Therefore, the washing water injection pipe 40 is separated first from the integrally extending tubular portion so that the connection portion is located at the center portion of the shaft, and the balloon-expansion liquid injection pipe 30 extends further from this and finally forms a stopper. For example, the axial cross-sectional size in the entire catheter can be set to be less than the cross-section of the urine discharge tube.

In addition, if necessary, the tube can be further added, wherein each tube has a different length as described above, and if the expansion portion such as a connection part or a stopper of the tube end is made smaller than the urine discharge tube section, the whole catheter section The axial cross section of the urine discharge tube axial cross section can be made small, making it easy to replace the gauze or instruments.

8A and 8B, the washing water inlet tube 40 of the present invention extends in the axial direction from the exposed end surface of the urine discharge tube sidewall so that the washing water is supplied to the urine discharge tube insertion end side through the internal washing water injection passage 27. The balloon expansion liquid injection pipe 30 extends in an axial direction from an end portion of the washing water injection pipe 40 so that the balloon expansion liquid is in communication with the washing water injection pipe sidewall and the urine discharge pipe sidewall through the expansion liquid injection passage 26. The injection portion of the balloon expansion liquid injection tube and the wash water injection tube may be positioned on the same shaft end surface by allowing the urine discharge tube to be injected into the balloon portion.

That is, while extending the washing water injection pipe 40 in the axial direction at the end of the urine discharge pipe side wall extending in the axial center direction to form a connecting portion 41, the balloon in the axial direction at the end of the side wall of the washing water injection pipe 40 The expansion liquid injection pipe 30 may be extended. At this time, the expansion liquid injection passage 26 of the balloon expansion liquid injection pipe 30 is formed long in the side wall of the wash water injection tube 40 and the side wall of the urine discharge pipe 20 so that the balloon expansion liquid is injected into the balloon of the urine discharge pipe. You can do that.

Here, the washing water injection pipe 40 extends from the end of the urine discharge pipe to the tube to form a connection portion 41, or to extend from or close to the urine discharge pipe 20 end portion to form a connection portion 41 can do. In addition, the balloon-expansion liquid injection pipe 30 may also be extended from a portion of the end of the washing water injection pipe or extended for a certain period of time to the tube to form a stopper 50 formed in the injection hole on the side. Of course, the stopper can also be disinfected by mounting a disinfection member.

In addition, as shown in Figure 9 by installing a flow sensor 70 on the inner surface of the urine discharge pipe 20 of the catheter 10 according to the present invention, the measurement information of the urine discharge amount can be provided to the server or terminal by wireless communication have.

The flow sensor transmits the measurement information to a nearby server or terminal by wireless communication, and the server or terminal receiving the measurement information checks the urine output of the patient so that the urine collector can be replaced, the statistical information can be used, and the health status can be checked. can do.

In the case of additionally installing the flow sensor by wireless communication, a power supply device may be additionally installed to supply power to the sensor, in which case the power supply device may be used in the same manner as the balloon expansion liquid injection pipe and the washing water injection pipe. It is installed extending in the axial direction from the surface of the discharge end of the urine discharge tube, the power supply line can be connected to the sensor through the inside of the urine discharge tube side wall.

The catheter 10 for urine discharge provided with the stopper 50 of the present invention constituted as described above is inserted into the insertion end 21 of the urine discharge tube 20 through the urethra or the upper pubic bone, and the balloon inflation fluid is injected. Injecting the inflation fluid into the interior through the tube to prevent the balloon portion from expanding in the endocardium to remove it from the insertion end of the catheter, to connect the urine discharge tube 20 to the urine collector to collect the urine in the endocardium, the catheter (10) In the human body insertion part, the outer surface of the catheter is covered with gauze and attached to the human skin.

Thus, the catheter 10 mounted on the human body separates the urine collector when the patient goes out, and the outlet of the urine discharge tube is closed by using a stopper formed in the balloon-expansion liquid injection tube 30 or the washing water injection tube 40 to urinate. This leakage can be prevented from leaking out.

In addition, the catheter 10 of the present invention is disposed by connecting the balloon expansion fluid injection pipe 30 and / or the wash water injection pipe 30 to the urine discharge pipe 20 so that the shaft cross-section does not overlap on the same axis, balloon expansion liquid injection Since the cross-sections of the pipe 20 and the washing water injection pipe 30 are smaller than the urine discharge pipe, the balloon-expansion liquid injection pipe and the washing water injection pipe are formed through the through-holes that surround the urine discharge pipe formed on the gauze or the device during the dressing process. All can be discharged, allowing easy replacement and mounting without cutting the gauze.

In addition, since the amount of urine discharge can be measured by the flow sensor 70 installed inside the urine discharge tube 20 of the catheter, it is possible to provide a device that provides convenience that can be easily identified by the urine collector replacement time or the urine volume meter.
