Description

Technical Field

[0001] This utility model belongs to the field of medical devices, and in particular relates to a bladder irrigation tube kit. Background Technology

[0002] A urinary catheter is a tube made of natural rubber, silicone rubber, or polyvinyl chloride (PVC) used to drain urine from the bladder. The catheter is inserted into the bladder through the urethra. After the catheter is inserted into the bladder, a balloon near the tip of the catheter secures the catheter in the bladder, making it less likely to fall out. At this time, the drainage tube is connected to a urine bag to collect urine.

[0003] Traditional bladder irrigation tubes are often designed for a single function, making it difficult to meet diverse clinical needs. In particular, when bladder irrigation and drug injection are required, the procedure is cumbersome and increases the risk of infection. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a bladder irrigation tube kit, which aims to solve the problems that the existing bladder irrigation tube kits are cumbersome to operate and easily increase the risk of infection.

[0005] The present invention adopts the following technical solution:

[0006] The bladder irrigation tubing kit includes an irrigation catheter and a conversion assembly. The conversion assembly includes a fixed sleeve with a fluid outlet connector on its front side and a rear side connected to the irrigation catheter. The fixed sleeve has a top opening at its upper end and a bottom opening at its lower end. A drug injection connector can be inserted into the top opening. The fixed sleeve contains a conversion head with a circular hole on its front side and a flow guide groove on its rear side, which communicates with the circular hole. A diversion groove is formed above the conversion head, and a flow guide channel is formed below the diversion groove on the conversion head, which communicates with the flow guide groove. The lower part of the conversion head is located inside the bottom opening, and a spring is fitted around the lower part of the conversion head.

[0007] Furthermore, the upper end face of the adapter has a socket, the bottom surface of the injection connector is a closed structure, a ring of liquid outlet holes is opened below the injection connector, and the bottom of the injection connector is provided with a plug that matches the socket.

[0008] Furthermore, the top opening includes an upper pressure port, and a lower pressure port is opened inside the upper pressure port. Both the upper and lower pressure ports are provided with retaining rings.

[0009] Furthermore, the injection connector is provided with a retainer that matches the upper pressure port.

[0010] Furthermore, the diameter of the injection connector matches the pressure port.

[0011] Furthermore, the bottom opening is a flat opening, and a guide head matching the flat opening is provided below the conversion head, with the guide head located inside the bottom opening.

[0012] Furthermore, the guide head is provided with the spring.

[0013] The beneficial effects of this utility model are as follows: In the initial state, the liquid outlet connector of this kit is connected to the flushing catheter through the conversion component. When medical staff use this kit to irrigate the patient's bladder, the doctor first locates the external urethral orifice, inserts the flushing catheter into the urethra, and connects the liquid outlet connector to the urine bag. After the preparation is completed, the bladder can be irrigated. During irrigation, the injection connector is inserted, and the connection between the conversion component and the liquid outlet connector is closed. The irrigation fluid is output from the injection connector and the flushing catheter into the bladder. After irrigating a certain amount, the injection connector is pulled out, the conversion component automatically resets, and the top of the conversion component is closed. The fluid in the bladder is discharged sequentially from the flushing catheter, the conversion component, and the liquid outlet connector into the urine bag.

[0014] In this design, the flushing and dispensing functions can be quickly switched by simply plugging and unplugging the injection connector. This design not only simplifies the operation steps but also improves treatment efficiency. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model patent 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 scope of the present utility model.

[0020] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0021] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0022] Combination Figure 1-4As shown, the bladder irrigation tubing kit includes an irrigation catheter 1 and a conversion assembly 23. The conversion assembly includes a fixing sleeve 5, with a liquid outlet connector 6 connected to the front side of the fixing sleeve 5 and a drainage channel 1 connected to the rear side. It has a top opening at the upper end and a bottom opening 7 at the lower end. A drug injection connector 8 can be inserted into the top opening. A conversion head 9 is provided inside the fixing sleeve 5. The conversion head 9 has a round hole 10 on the front side and a flow guide groove 11 on the rear side, which is connected to the round hole 10. A diversion groove 12 is formed above the conversion head 9. A flow guide channel 13 is formed below the diversion groove 12 on the conversion head 9, which is connected to the flow guide groove 13. The lower part of the conversion head 9 is located inside the bottom opening 7, and a spring 14 is fitted on the lower part of the conversion head 9.

[0023] like Figure 1 The flushing catheter 1 has an existing structure. One end of the flushing catheter 1 has a water inlet connector 2 on its side wall, and the other end has an air balloon 3 and a urinary catheter head 4. The air balloon 3 is located on the outer periphery of the flushing catheter, and the urinary catheter head 4 is connected to the flushing catheter 1. The inner wall of the flushing catheter 1 has a slender water tube, and the front and rear ends of the water tube are connected to the water inlet connector 2 and the air balloon 3, respectively.

[0024] In its initial state, the dispensing connector of this kit is connected to the irrigation catheter via a conversion component. When medical personnel use this kit to irrigate a patient's bladder, the doctor first locates the external urethral orifice and slowly inserts the catheter tip into the bladder as instructed. Next, a measured amount of sterile saline solution is slowly injected into the injection connector. The sterile saline solution flows through the water tube into the balloon, which inflates to secure the irrigation catheter and prevent it from dislodging. A suitable urine bag is then selected, the dispensing connector is connected to the urine bag, and it is secured to the bedside, ensuring the urine bag is below the bladder level to prevent urine reflux. After preparation, the bladder can then be irrigated.

[0025] When using this kit to flush the bladder, first insert the injection connector into the top opening. The injection connector pushes the conversion head downwards a short distance within the fixed sleeve. The bottom of the conversion head protrudes from the bottom opening of the fixed sleeve, and the spring deforms under the pressure of the conversion head. When the bottom of the injection connector extends into the fixed sleeve, the outlet of the injection connector connects to the flushing catheter through the diversion groove and guide groove, and the round hole is no longer connected to the flushing catheter. At this time, a measured amount of flushing fluid is slowly injected into the injection connector. The flushing fluid passes through the diversion groove, guide channel, and guide groove in sequence, and finally enters the flushing catheter, flowing out from the catheter head to flush the bladder. After flushing a certain amount, pull out the injection connector. The conversion component automatically resets, the top opening of the conversion component is closed, and the fluid in the bladder is discharged sequentially from the flushing catheter, conversion component, and outlet connector into the urine bag.

[0026] As a specific structure, the upper end face of the conversion head 9 has a socket 15, the bottom surface of the drug injection connector 6 is a closed structure, a ring of liquid outlet holes 16 is opened below the drug injection connector 6, and the bottom of the drug injection connector 8 is provided with a plug 17 that matches the socket 15.

[0027] After the lower end of the injection connector is inserted into the top opening, the plug is first inserted into the socket, and then the injection connector is pushed down slightly. At that time, the injection connector moves down a short distance by pressing down the adapter head through the plug until the injection connector is fully inserted and the injection connector is connected to the flushing catheter.

[0028] In this kit, the top opening includes an upper pressing opening 18, and a lower pressing opening 19 is formed inside the upper pressing opening 18. Both the upper and lower pressing openings are equipped with retaining rings 20.

[0029] The injection connector is equipped with a retaining sleeve 22 that matches the upper pressure port, and the diameter of the injection connector matches the lower pressure port. The design of the injection connector and its top port allows for proper insertion. When the plug below the injection connector is inserted into the socket, and the connector is pushed downwards with slight force, the lower bottom surface of the retaining sleeve contacts the inner bottom surface of the upper pressure port, indicating that the injection connector is fully inserted and connected to the flushing conduit through the outlet hole. Simultaneously, the adapter head moves downwards, compressing the spring. Because both the upper and lower pressure ports have retaining rings, there is friction between the two retaining rings and the retaining sleeve and injection connector, respectively, and the spring force is relatively small. After the injection connector is fully inserted, it is locked into the fixing sleeve. Additionally, the retaining rings also provide a sealing effect.

[0030] As a further preferred structure, the bottom opening 7 is flat, and a guide head 21 matching the flat opening is provided below the conversion head 9, with the guide head 21 located inside the bottom opening 7. The flat design of the bottom opening, with the guide head located inside, allows the guide head to be confined by the bottom opening, preventing the conversion head from rotating within the fixed sleeve during the entire bladder flushing process, thus avoiding interference and reducing the flushing effect.

[0031] In addition, the guide head 21 is provided with the spring 14. When the injection connector pushes the conversion head to move downward inside the fixed sleeve, the spring is gradually compressed during this process, and the guide head passes through the bottom opening of the fixed sleeve.

[0032] After bladder irrigation using the injection connector is completed, the injection connector is pulled out. Under the action of the spring, the conversion head returns to its initial state. Then, the discharge connector reconnects to the irrigation catheter through the round opening and the guide groove, and the urine is collected in the urine bag through the irrigation catheter and the discharge connector. Additionally, if the conversion head becomes stuck in the fixing sleeve, the guide head can be manually pushed until it returns to its initial state.

[0033] 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.
