Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to an expansion and drainage device. Background Art
[0002] Urology is a department that mainly diagnoses and treats urinary system diseases. Usually, patients in urology will experience urination problems after surgery and need to use drainage devices to drain urine. Therefore, the use of drainage devices is relatively common in urology, and a catheter is usually required to drain urine.
[0003] The current urinary catheter has a simple structure, and some patients are prone to urinary crystals in their urine, which can cause obstruction in the flow of urine in the catheter and shorten the service life of the catheter. This not only increases the cost of replacing the catheter, but also frequent replacement of the catheter will have an adverse effect on the stoma, making it less practical. Utility Model Content
[0004] The purpose of the present invention is to provide an expansion drainage device in order to solve the above problems, as described below.

[0007] Using the above-mentioned expansion drainage device, the closed end of the main pipe can be extended into the bladder from the skin stoma, so that the sac structure is located inside the bladder. Water is injected into the sac structure through the water injection tube to make it swell and prevent it from falling out of the stoma. Subsequently, when urine crystals are produced, the crystals accumulate inside the main pipe. The ball is pulled out from the end of the main pipe through the pulling structure. At this time, the ball can bring out the urine crystals accumulated inside the main pipe and continue to be used.
[0008] Preferably, the capsule structure includes a cavity opened in the wall of the main tube, and the outer wall of the cavity is thinner than the inner wall.
[0009] Preferably, a connecting pipe is integrally formed on the inner wall of the main pipe, and both ends of the connecting pipe are respectively connected to the clamping cavity and the water injection pipe, and the end of the water injection pipe is fixedly connected to a rubber pad.
[0010] Preferably, a limiting ring abutting against the ball is fixedly connected to the inner wall of the closed end of the main pipe.
[0011] Preferably, the pulling structure includes a connecting rope fixedly connected to the ball, and the open end of the main pipe is integrally formed with a hard tube, and the hard tube is provided with a clamping structure for fixing the end of the connecting rope.
[0012] Preferably, the clamping structure includes a cross bar fixedly connected to the end of the connecting rope, and both sides of the inner wall of the hard tube are provided with clamping grooves that are clamped to the end of the cross bar.
[0013] Preferably, the end of the connecting rope is fixedly connected to a pull head.
[0014] The beneficial effects are:
[0015] By extending the closed end of the main tube into the bladder through the skin stoma, the sac structure is located inside the bladder, and water is injected into the sac structure through the water injection tube to make it swell and prevent it from falling out of the stoma. Subsequently, when urine crystals are produced, the crystals accumulate inside the main tube. The ball is pulled out from the end of the main tube through the pulling structure. At this time, the ball can bring out the urine crystals accumulated inside the main tube and continue to use it, avoiding frequent replacement of the catheter due to blockage of urine crystals and increasing the service life of the catheter.

[0022] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
[0023] See also Figure 1-Figure 3 As shown, the utility model provides an expansion drainage device, including a main pipe 1, a liquid outlet 2 connected to the interior of the main pipe 1 is provided on one side of the closed end thereof, a capsule structure 3 is provided on the side of the liquid outlet 2 away from the closed end of the main pipe 1, and the capsule structure 3 is integrally formed with the main pipe 1, and a water injection pipe 6 for injecting water into the capsule structure 3 is connected to the side wall of the main pipe 1 close to the opening side, a ball 4 is sleeved inside the closed end of the main pipe 1 and abutted against the inner wall thereof, and a pulling structure is provided at the open end of the main pipe 1 for driving the ball 4 to move out.
[0024] As an optional embodiment, the sac structure 3 includes a clamping cavity 31 opened in the wall of the main tube 1, the outer wall of the clamping cavity 31 is thinner than the inner wall, and the inner wall of the main tube 1 is integrally formed with a connecting tube 8, the two ends of the connecting tube 8 are respectively connected to the clamping cavity 31 and the water injection pipe 6, and the end of the water injection pipe 6 is fixedly connected to a rubber pad 9. The rubber pad 9 can first inject water into the water injection pipe 6 after the syringe needle is inserted. When the needle is pulled out, it prevents liquid leakage. The injected liquid passes through the water injection pipe 6 and the connecting tube 8 and enters the clamping cavity 31. Since the outer wall of the clamping cavity 31 is thin, it can bulge outward.
[0025] Specifically, a limiting ring 7 is fixedly connected to the inner wall of the closed end of the main pipe 1 and abuts against the ball 4. The limiting ring 7 can limit the ball 4 and restrict it to the end of the main pipe 1 to prevent the ball 4 from moving and dislocating inside the main pipe 1.
[0026] Reference Figure 3 As shown, the pulling structure includes a connecting rope 5 fixedly connected to the ball 4, and a hard tube 10 is integrally formed at the open end of the main pipe 1. The hard tube 10 is provided with a clamping structure for fixing the end of the connecting rope 5. The clamping structure includes a cross bar 11 fixedly connected to the end of the connecting rope 5. Both sides of the inner wall of the hard tube 10 are provided with a clamping groove 12 clamped with the end of the cross bar 11. The end of the connecting rope 5 is fixedly connected with a pull head 13, and the end of the connecting rope 5 can be pulled by the pull head 13 to move, driving the cross bar 11 to cancel the clamping with the clamping groove 12. At the same time, when the cross bar 11 is clamped with the clamping groove 12, the end of the connecting rope 5 is fixed, preventing the end of the connecting rope 5 from retracting, and facilitating pulling of the connecting rope 5.
[0027] With the above structure, the closed end of the main pipe 1 can be extended into the bladder through the skin stoma, so that the sac structure 3 is located inside the bladder. Water is injected into the sac structure 3 through the water injection pipe 6 to make it swell and prevent it from falling out of the stoma. Subsequently, when urine crystals are produced, the crystals accumulate inside the main pipe 1. The ball 4 is pulled out from the end of the main pipe 1 through the pulling structure. At this time, the ball 4 can take out the urine crystals accumulated inside the main pipe 1 and continue to be used.
[0028] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
