Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, in particular to an external joint component of a urinary catheter. Background Art

[0002] A urinary catheter is a tube that is inserted through the urethra into the bladder to drain urine. It is made of natural rubber, silicone rubber or polyvinyl chloride and can be inserted through the urethra into the bladder to drain urine. After the catheter is inserted into the bladder, there is an air bag near the tip of the catheter to fix the catheter in the bladder and prevent it from falling out. The drainage tube is connected to a urine bag to collect urine.

[0003] A urinary catheter generally includes an injection hole and a liquid outlet, wherein the injection hole is sealed with a rubber plug connector. However, during the syringe insertion and flushing process, the existing rubber plug connector is prone to leakage due to multiple punctures. If leakage occurs, the entire catheter needs to be scrapped, increasing the loss. Moreover, if the catheter leaks after being inserted into the patient's body, it needs to be replaced and re-inserted, increasing the pain of treatment. Utility Model Content

[0004] The purpose of the present utility model is to provide a urinary catheter external connector component to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a urinary catheter external joint component, comprising a urinary catheter and a connector, wherein one end of the urinary catheter is provided with a water injection pipe, and one end of the water injection pipe is provided with a connector, wherein the connector comprises a front connecting post and a spare connecting post, wherein the center of the front connecting post and the center of the spare connecting post are both provided with a water through hole, the top of the outer wall of the front connecting post and the bottom of the outer wall of the spare connecting post are both provided with external threads, and a connecting ring is provided between the front connecting post and the spare connecting post;

[0006] The bottoms of the inner walls of the two water holes are each provided with an annular groove, and expansion rings are embedded in the interiors of the two annular grooves. The bottom ends of the front connecting column and the spare connecting column are each provided with a plurality of water absorption holes.

[0007] As a preferred technical solution of the present invention, the inner wall of the connecting ring is provided with an internal thread, and the connecting ring is threadably connected to the two external threads via the internal thread.

[0008] As a preferred technical solution of the present invention, one end of the water injection pipe is fixedly connected to the top of the spare connecting column, and the water hole inside the spare connecting column is connected to the inside of the water injection pipe.

[0009] As a preferred technical solution of the present invention, an anti-slip ring is fixedly connected to the inner wall of the expansion ring, and the anti-slip ring is made of elastic silicone.

[0010] As a preferred technical solution of the present invention, the plurality of water absorption holes are arranged in a circle, and the water absorption holes are communicated with the interior of the annular groove.

[0011] As a preferred technical solution of the present invention, the edge of the anti-slip ring is bonded and fixed to the inner wall of the annular groove by a waterproof adhesive.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model provides a front connecting column and a spare connecting column, which are connected by means of a connecting ring. The flushing operation can be achieved by plugging the front connecting column and the syringe first. When repeated use causes deformation or damage that is difficult to remedy, that is, when the syringe connection leaks very seriously, the front connecting column can be disassembled and discarded. At this time, the connection and flushing operation is performed with the help of the spare connecting column, which is equivalent to quickly replacing a new connecting part. The partial damage is discarded without affecting the continued use of the entire catheter, saving energy consumption. At the same time, the disassembly steps are simple and do not affect the treatment process.

[0014] 2. The utility model sets an expansion ring in the water hole inside the front connecting column and the spare connecting column, and uses multiple water absorption holes and anti-slip rings. When a slight leakage occurs due to the expansion and relaxation of the water hole opening, the water can be first introduced into the annular groove to make the expansion ring larger. This protrudes from the inner wall of the water hole, which is equivalent to tightening the inner diameter of the water hole. In this way, the connection can be tighter when the syringe is inserted. The enlarged expansion ring fits with the water outlet of the syringe to reduce leakage. When the structural components are not completely damaged, the structure can be remedied to increase the service life. At the same time, when the catheter is inserted into the patient's body, there is no need to remove and replace it due to leakage problems, which reduces the pain of treatment.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1 to 3 The utility model provides a technical solution for the external connector of a urinary catheter:

[0021] Example 1:

[0022] according to Figure 1 、 Figure 2 As shown, a urinary catheter external joint component includes a urinary catheter 1 and a connector. A water injection pipe 2 is provided at one end of the urinary catheter 1, and a connector is provided at one end of the water injection pipe 2. The connector includes a front connecting column 4 and a spare connecting column 3. A water hole 8 is provided at the center of the front connecting column 4 and the center of the spare connecting column 3. The top of the outer wall of the front connecting column 4 and the bottom of the outer wall of the spare connecting column 3 are provided with an external thread 6. The two external threads 6 are continuously arranged and matched with the internal thread 7. A connecting ring 5 is provided between the front connecting column 4 and the spare connecting column 3.

[0023] The inner wall of the connecting ring 5 is provided with an internal thread 7, and the connecting ring 5 is threadedly connected to the two external threads 6 through the internal thread 7. One end of the water injection pipe 2 is fixedly connected to the top of the spare connecting column 3, and the water hole 8 inside the spare connecting column 3 is connected to the inside of the water injection pipe 2.

[0024] During specific use, the utility model provides a catheter external joint component. When the medical staff uses the catheter 1 to perform water injection and flushing operations, it is necessary to use a syringe to connect the connector on the water injection pipe 2 to inject water for flushing. During the first few operations, the medical staff can connect the syringe to the front connecting column 4, specifically insert the eyelet of the syringe into the water through hole 8 of the front connecting column 4, so that water flows along the water through hole 8 of the front connecting column 4 into the water through hole 8 of the spare connecting column 3, and then enters the water injection pipe 2. After the first few syringe plugging operations, the water through hole 8 of the front connecting column 4 will expand, relax, or even crack at the opening. When deformation or damage that is difficult to remedy occurs, that is, when the syringe connection leaks very seriously, the connecting ring 5 can be manually twisted and unscrewed from the external thread 6, so that the front connecting column 4 is separated from the spare connecting column 3, and the front connecting column 4 can be discarded. In this way, the spare connecting column 3 is plugged in with the syringe to achieve water injection and flushing.

[0025] Example 2:

[0026] Based on the first embodiment, Figure 1 and Figure 3 As shown, an annular groove 10 is provided at the bottom of the inner wall of the two water holes 8, and an expansion ring 11 is embedded in the interior of the two annular grooves 10. The expansion ring 11 is made of water-swelling rubber, and a plurality of water absorption holes 9 are provided at the bottom end of the front connecting column 4 and the bottom end of the spare connecting column 3. The inner wall of the expansion ring 11 is fixedly connected with an anti-slip ring 12, and the anti-slip ring 12 is made of elastic silicone. In this way, when the internal expansion ring 11 swells and bulges, the anti-slip ring 12 also produces a corresponding bulge deformation, causing the expansion ring 11 to bulge, and a plurality of water absorption holes 9 are arranged in a circle, and the water absorption holes 9 are connected to the inside of the annular groove 10. The edge of the anti-slip ring 12 is bonded and fixed to the inner wall of the annular groove 10 by a waterproof adhesive. Water will not enter through the anti-slip ring 12, and therefore the normal syringe water injection operation will not cause the expansion ring 11 to swell.

[0027] During specific use, the utility model provides a catheter external joint component. During the operation of plugging and flushing the front connecting column 4 or the spare connecting column 3 with the syringe, if the connection port of the front connecting column 4 or the spare connecting column 3 is slightly enlarged or deformed, resulting in slight water leakage, the bottom surface of the front connecting column 4 or the spare connecting column 3 can be faced to the water and placed on the water surface for a few seconds. After water enters the multiple water absorption holes 9, the water enters the annular groove 10. The expansion ring 11 in the annular groove 10 is made of water-swelling rubber, and its volume expands. Due to the limiting effect of the annular groove 10, the expanded expansion ring 11 expands into the water hole 8 and protrudes from the annular groove 10, which is equivalent to tightening the inner diameter of the water hole 8. In this way, the syringe can be inserted to connect more tightly, and the expanded expansion ring 11 is fitted with the water outlet of the syringe to reduce water leakage.
