Description

Technical Field

[0001] This utility model belongs to the field of medical consumables technology, and in particular relates to a quick-connect switching bladder irrigation tube. Background Technology

[0002] A bladder irrigation tube is a specialized medical consumable used to connect the irrigation solution container, the catheter, and the urine collection bag for bladder irrigation.

[0003] The bladder irrigation tubing includes a converter with three ports for connecting to a urinary catheter, a collection catheter, and an irrigation tubing. The irrigation tubing connects to an irrigation fluid container, and the collection catheter connects to a collection bag. The collection and irrigation tubing ports have valves, and the urinary catheter has a stop-flow clamp. Before use, the two valves are closed. During use, first connect the irrigation tubing, then open the valve on the irrigation tubing port. The irrigation fluid flows from the irrigation tubing, converter, and urinary catheter into the patient's bladder for irrigation. Then, close the irrigation tubing valve, open the collection catheter valve, and close the irrigation tubing valve. Waste irrigation fluid from the bladder is collected from the urinary catheter and collection catheter into the collection bag. Therefore, switching valves is required during operation, making the procedure relatively complex. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a quick-connect switching bladder irrigation tube, which aims to solve the above technical problems.

[0005] The following technical solution is adopted in this utility model:

[0006] The quick-connect switching bladder irrigation tube includes a catheter and a conversion connector. The conversion connector includes a cylindrical housing with a first port at one end and a second and third port on its side wall. The catheter is connected to the second port. A switching core is provided inside the housing. The switching core includes a central column with a cylindrical shape at one end and a guide column at the other end. The central column has a central cavity with a groove and a circular hole communicating with the groove on its side. A central flow channel communicating with the central cavity is formed on one end face of the central column. The port of the central flow channel abuts against the inner wall of the end face of the housing. The central column has an inlet flow channel with the port of the inlet flow channel contacting the inner wall of the first port. A compression spring is provided on the guide column, and the guide column extends out of the housing.

[0007] Furthermore, the position of the second opening corresponds to the groove, and the position of the third opening corresponds to the circular hole.

[0008] Furthermore, the cylinder has a central hole, and a contact hole is formed at the bottom of the central hole, which is connected to the inlet channel.

[0009] Furthermore, the intermediate flow channel is L-shaped, and the inlet flow channel is a single ring.

[0010] Furthermore, the guide post is a hexagonal post, and the housing has hexagonal holes that match the hexagonal post.

[0011] Furthermore, there is a retaining ring on the outer wall of the first pipe opening.

[0012] The beneficial effects of this invention are as follows: This product structure does not use a switching valve. In the initial state, the second and third ports are connected through a groove and a round hole. When flushing is required, the flushing connector is directly inserted into the first port, driving the internal switching core to move, thus connecting the flushing connector with the second port, allowing the flushing fluid to enter the bladder. After flushing, the flushing connector is removed, the switching core automatically resets, and the second and third ports automatically connect, allowing the flushing waste fluid in the bladder to drain into the urine collection bag through the third port. The entire process only requires inserting and removing the flushing connector, making operation simple. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0019] like Figure 1-4As shown, the quick-connect switching bladder irrigation tube provided in this embodiment includes a urinary catheter A and a conversion connector B. The conversion connector B includes a cylindrical housing 1. One end of the housing 1 has a first port 2, and the side wall is provided with a second port 3 and a third port 4. The urinary catheter A is connected to the second port 3. The housing 1 is provided with a switching core 5. The switching core 5 includes a central column 51. One end of the central column 51 forms a cylinder 52, and the other end forms a guide column 53. The central column 51 has a central cavity 54. The side of the central cavity 54 has a groove 55 and a circular hole 56 communicating with the groove. One end face of the central column 51 has a central flow channel 57 communicating with the central cavity 54. The port of the central flow channel 57 abuts against the inner wall of the end face of the housing 1. The central column 51 has an inlet flow channel 58. The port of the inlet flow channel 58 contacts the inner wall of the first port 2. The guide column 53 has a compression spring 59, and the guide column 53 extends out of the housing 1.

[0020] The guide post 53 is a hexagonal post, and the housing 1 has a hexagonal hole that matches the hexagonal post. The guide post serves to guide the movement.

[0021] In the initial state, under the force of spring 59, the position of the second tube opening 3 corresponds to the groove 55, and the position of the third tube opening 4 corresponds to the circular hole 56. The length of the groove is at least twice the diameter of the circular hole. In use, the second tube opening 3 is connected to the catheter A, and the third tube opening 4 is connected to the urine collection bag (not shown in the figure).

[0022] Urinary catheter A is an existing technology, generally using a balloon to inflate and secure it at the bladder opening. The urinary catheter A has a water or air nozzle on its side wall, and a thin tube connects to the balloon through the inner wall of the catheter. The balloon is inflated by injecting water or air. Before use, the catheter tip is inserted into the urethra, and once it reaches the bladder, the balloon is inflated.

[0023] Under normal circumstances, the second and third tube openings are connected by grooves and round holes, allowing fluid in the bladder to drain into the urine collection bag. When flushing is required, the flushing connector C is directly inserted into the first tube opening 2. The flushing connector C connects to the flushing tube and has a stepped structure that matches the internal structure of the first tube opening. Figure 2 As shown, the cylinder 52 has a central hole 521, and a contact hole 522 is formed at the bottom of the central hole 521. The contact hole 522 communicates with the inlet channel 58. The intermediate channel 57 is L-shaped, and the inlet channel 58 is a single ring.

[0024] After the flushing connector C is inserted, its tip is inserted into the contact hole 522. As it continues to be inserted, the internal switching core moves. At this time, the flushing fluid from the flushing connector C enters through the contact hole 522, then flows to each inlet channel 58, and then is distributed to each intermediate channel, finally entering the intermediate cavity 54. When pushed to the lowest position, the round hole 56 is completely intersected with the third pipe opening 4, so the round hole 56 is blocked. However, the second pipe opening 3 is always connected to the groove 55, so the flushing fluid will enter the second pipe opening 3 and then enter the bladder for flushing.

[0025] After rinsing for a period of time, remove the rinsing connector. The switching core will automatically reset after rinsing, and the second and third tubes will automatically connect, allowing the bladder's rinsing waste to drain into the urine collection bag through the third tube. This product does not use a switching valve; the entire process only requires plugging and unplugging the rinsing connector, making it simple to operate.

[0026] In addition, the flushing connector C shown in the diagram has a cap around its outer circumference. After the flushing connector C is inserted, the cap comes into contact with and presses against the first pipe opening 2, creating a large frictional force that is much greater than the restoring force of the spring, allowing the flushing connector C to be stably inserted into the first pipe opening. Furthermore, the outer wall of the first pipe opening 2 has a retaining ring 21, which further increases the frictional force.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
