Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bladder flushing, in particular to a bladder flushing connector. Background Art
[0002] Bladder irrigation is a method of using a catheter to inject a solution into the bladder and then draining the injected liquid out using the siphon principle.
[0003] Traditional urinary catheters are not clinically capable of bladder irrigation. However, in clinical practice, in order to avoid the pain and financial burden of repeated catheterization on patients, an infusion set is directly connected to the Y-shaped connector of the scalp needle puncture catheter. However, improper operation may damage the catheter, causing it to leak urine or air, and thus slip out of the bladder. Although there are currently urinary catheter interfaces, the connection between these catheter interfaces and the catheter in actual use relies solely on the friction of the thread, which may cause the risk of falling off. At the same time, in actual use, they rely on a valve to close the infusion port. When in use, the valve is open and there will be a certain amount of time to insert the infusion tube into the infusion port, increasing the chance of external gas entering the catheter. Utility Model Content
[0004] In view of the deficiencies of the prior art, the present invention provides a bladder irrigation connector, which has the advantages of preventing the connection from falling off and reducing the opening time of the injection port during injection, thereby solving the problems raised by the above-mentioned background technology.

[0006] As a preferred technical solution of the present invention, the catheter connection port is tapered, and the outer wall of the catheter connection port is provided with threads.
[0007] As a preferred technical solution of the present invention, there is a certain distance between the inner wall of the sleeve and the outer wall of the tube body, and the spring and the clip are located between the tube body and the sleeve.
[0008] As an optimal technical solution of the present invention, extension blocks are provided on both sides of the outer wall of the sealing plug, and two limiting grooves are provided on the inner wall of the branch pipe near the extension blocks on both sides of the outer wall of the sealing plug, and the extension blocks on both sides of the outer wall of the sealing plug are located in the limiting grooves of the inner wall of the branch pipe.
[0009] As an optimal technical solution of the present invention, a notch is provided on the top of the reed, and the outer dimensions of the notch are adapted to the outer dimensions of the connecting block, and the connecting block is located in the notch on the top of the reed, and the reed and the connecting block are rotatably sleeved.
[0010] As a preferred technical solution of the present invention, the number of the threaded column, rotating button, reed, clip and connecting block is two, and the two threaded columns, rotating button, reed, clip and connecting blocks are symmetrically arranged on the upper and lower inner walls of the shell.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. The bladder irrigation connector is configured such that the catheter is sleeved on the outer wall of the catheter connection port and pushed toward the housing so that the catheter enters the interlayer between the housing and the tube body. At this time, the rotating knob is rotated to drive the threaded column and the connecting block to rotate. The threaded column and the housing are threadedly connected, so that the threaded column moves downward on the inner wall of the housing, thereby moving the reed downward. The reed drives the clip downward, so that the clip overlaps the outer wall of the catheter inside the housing. By rotating the two threaded columns to the bottom, the two clips clamp the outer wall of the catheter.
[0013] 2. The bladder flushing connector is constructed by removing the sealing cover from the top outer wall of the branch tube and inserting the infusion head into the top inner part of the branch tube. At this time, cleaning liquid is injected into the inner wall of the branch tube. The water pressure of the cleaning liquid pushes the sealing plug downward, causing the sealing plug to drive the spring to contract. At this time, the top of the sealing plug is separated from the inner wall of the branch tube, thereby creating a gap between the sealing plug and the branch tube. At this time, through the gap between the sealing plug and the branch tube, the cleaning liquid enters the inner wall of the tube body through the sealing plug and moves through the tube body to the inside of the urinary catheter, thereby cleaning the patient's bladder.

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.
[0021] See also Figure 1 - Figure 5 The bladder irrigation connector comprises a tube body 1, the outer wall of the tube body 1 is fixedly mounted with a shell 2 and a branch pipe 3, one end of the tube body 1 is fixedly mounted with a catheter connection port 5, the other end of the tube body 1 is fixedly mounted with a urine bag connection port 4, the inner wall of the branch pipe 3 is fixedly mounted with a cross seat 6, the inner wall of the branch pipe 3 is provided with a spring 7, the inner wall of the branch pipe 3 is slidably connected with a sealing plug 8, and the top outer wall of the branch pipe 3 is movably sleeved with a sealing cover 9, the inner wall of the shell 2 is threadedly connected with a threaded column 10, the inner wall of the shell 2 is fixedly mounted with one end of a reed 12, the other end of the reed 12 is fixedly mounted with a clip 13, the top of the threaded column 10 is fixedly mounted with a rotating button 11, and the bottom of the threaded column 10 is fixedly mounted with a connecting block 14. In the above structure, a conical block is provided on the top of the sealing plug 8. The conical block will disperse the water after being impacted by water pressure, so that the cleaning fluid entering the inside of the branch pipe 3 through the sealing plug 8 will not have an excessive flow rate, thereby causing damage to the patient's body.
[0022] In a preferred embodiment, the catheter connection port 5 is tapered, and the outer wall of the catheter connection port 5 is provided with a thread. In the above structure, the catheter is sleeved on the outer wall of the end with a smaller diameter of the catheter connection port 5, and the catheter is pushed in the direction of the catheter connection port 5, so that the catheter connection port 5 opens the connection of the catheter through the tapered shape, and the friction between the catheter connection port 5 and the catheter is increased by the thread on the outer wall of the catheter connection port 5.
[0023] In a preferred embodiment, there is a certain distance between the inner wall of the housing 2 and the outer wall of the tube body 1, and the reed 12 and the clip 13 are located between the tube body 1 and the housing 2. In the above structure, when the urinary catheter reaches between the housing 2 and the tube body 1, the reed 12 is pressed downward, so that the reed 12 drives the clip 13 to be pressed downward, thereby causing the clip 13 to overlap with the outer wall of the urinary catheter. By clamping the outer wall of the urinary catheter with the clip 13, the urinary catheter is fixed.
[0024] In a preferred embodiment, extension blocks are provided on both sides of the outer wall of the sealing plug 8, and two limiting grooves are provided on the inner wall of the branch pipe 3 near the extension blocks on both sides of the outer wall of the sealing plug 8, and the extension blocks on both sides of the outer wall of the sealing plug 8 are located in the limiting grooves of the inner wall of the branch pipe 3. In the above structure, when the sealing plug 8 moves, the extension blocks on its outer wall will follow the sealing plug 8, and then the extension blocks on the outer wall of the sealing plug 8 will be limited by the limiting grooves on the inner wall of the tube body 1, so that the sealing plug 8 will not rotate when moving up and down.
[0025] In a preferred embodiment, a notch is provided at the top of the spring 12, and the outer dimensions of the notch are adapted to the outer dimensions of the connecting block 14, and the connecting block 14 is located in the notch at the top of the spring 12, and the spring 12 and the connecting block 14 are rotatably sleeved. In the above structure, when the threaded column 10 rotates, the threaded column 10 drives the connecting block 14 to rotate on the inner wall of the spring 12, so that when the spring 12 moves downward through the thread, the end of the spring 12 close to the clip 13 is pressed downward through the connecting block 14.
[0026] In a preferred embodiment, the number of the threaded column 10, the rotating button 11, the reed 12, the clip 13 and the connecting block 14 is two, and the two threaded columns 10, the rotating button 11, the reed 12, the clip 13 and the connecting block 14 are symmetrically arranged on the upper and lower inner walls of the housing 2. In the above structure, by rotating the two rotating buttons 11, the two rotating buttons 11 drive the two threaded columns 10 to rotate, and then the threaded column 10 moves downward through the thread of the outer wall, and then presses the two reeds 12 toward the outer wall of the tube body 1, so that the two clips 13 clamp the outer wall of the catheter on the outer wall of the tube body 1.
[0027] Working principle: by sleeve-fitting the urinary catheter on the outer wall of the end with the smaller diameter of the urinary catheter connection port 5 and pushing the urinary catheter toward the housing 2, the urinary catheter enters between the housing 2 and the tube body 1. At this time, the rotating knob 11 is rotated, so that the rotating knob 11 drives the threaded column 10 and the connecting block 14 to rotate. Through the threaded connection between the threaded column 10 and the housing 2, the threaded column 10 moves downward on the inner wall of the housing 2, thereby causing the reed 12 to move downward. The reed 12 drives the clip 13 to move downward, so that the clip 13 overlaps the outer wall of the urinary catheter of the housing 2. By rotating the two threaded columns 10 to the bottom, the two clips 13 clamp the outer wall of the urinary catheter. , connect the urine bag connection port 4 to the urine bag. When it is necessary to flush the inside of the patient's bladder, remove the sealing cover 9 from the top outer wall of the branch pipe 3 and insert the infusion head into the top inner part of the branch pipe 3. At this time, the cleaning liquid is injected into the inner wall of the branch pipe 3. The water pressure of the cleaning liquid pushes the sealing plug 8 downward, and the sealing plug 8 drives the spring 7 to contract. At this time, the top of the sealing plug 8 is separated from the inner wall of the branch pipe 3, thereby creating a gap between the sealing plug 8 and the branch pipe 3. At this time, through the gap between the sealing plug 8 and the branch pipe 3, the cleaning liquid passes through the sealing plug 8 into the inner wall of the tube body 1, moves through the tube body 1 to the inside of the urinary catheter, and then cleans the patient's bladder.
