Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a protective cap for a urinary catheter flushing cavity. Background Art

[0002] A urinary catheter is a tube that is inserted into the bladder through the urethra to drain urine. It is a tube made of natural rubber, silicone rubber or polyvinyl chloride, which can be inserted into the bladder through the urethra to drain urine. After the urinary catheter is inserted into the bladder, there is an air bag near the head of the catheter to fix the catheter in the bladder and prevent it from coming out easily. The drainage tube is connected to a urine bag to collect urine. However, when flushing the urinary catheter (such as a three-lumen urinary catheter), it is necessary to inject liquid into the external injection tube of the urinary catheter. When the injection tube is pulled out after the injection and flushing is completed, the residual liquid in the urinary catheter will flow out through the tube wall, and there is a lack of blocking of the tube.

The barrier component is arranged in the urinary catheter to block the injected liquid and prevent the liquid from flowing back. The insertion component is arranged in the urinary catheter for insertion, docking, installation and protection. The liquid injection component is arranged on the insertion component for docking installation to inject liquid for flushing.

The barrier component 2 includes a mounting plate 201, a connecting plate 202, a fixing column 203, a circular plate 204, a valve 205, and a valve 206. 05, mounting tube 206 and flat rubber tube 207, the mounting plate 201 is arranged in the urinary catheter 1, the connecting plates 202 are evenly distributed on the mounting plate 201, the fixing column 203 is fixedly mounted on one side outer wall of the mounting plate 201, the circular plate 204 is fixedly mounted on one end of the fixing column 203, the valve 205 is evenly distributed on the circular plate 204, the mounting tube 206 is arranged in the urinary catheter 1, and the flat rubber tube 207 is slidably mounted on the mounting tube 206. The urinary catheter can be a three-chamber urinary catheter.

[0025] First, the liquid is blocked by the flat hose 207. Since the flat hose 207 has a flat shape, the liquid cannot stretch the flat hose 207. When too much liquid gathers, part of the liquid enters through the opening gap of the flat hose 207. At this time, the liquid is blocked by the valve 205. When the liquid pushes the valve 205, the valve 205 is blocked by the connecting plate 202 and does not bend, so it cannot form an opening to block the liquid.

[0026] Among them, the insertion component 3 includes a concave block 301, a circular tube 302 and two sealing rings 303. The concave block 301 is set on the catheter 1, and the circular tube 302 is fixedly installed on the outer wall of one side of the concave block 301. The two sealing rings 303 are both sleeved on the circular tube 302, and the installation tube 206 is fixedly connected to the circular tube 302.

[0027] Specifically, pick up the concave block 301 , align the round tube 302 with the urinary catheter 1 , push the concave block 301 , and the concave block 301 drives the round tube 302 to move, and the round tube 302 moves and is inserted into the urinary catheter 1 .

[0028] Furthermore, the outer wall of the circular tube 302 is arranged in a wave-step shape, and the circular tube 302 is adapted to the urinary catheter 1 .

[0029] Among them, the injection component 4 includes a fixed plate 401, a docking concave plate 402, two sealing rings 403, a drainage pipe 404, a limiting plate 405, an insertion pipe 406 and an injection hose 407. The fixed plate 401 is arranged on one side of the concave block 301, the docking concave plate 402 is fixedly installed on the outer wall of one side of the fixed plate 401, the two sealing rings 403 are both sleeved on the docking concave plate 402, the drainage pipe 404 is evenly distributed on the outer wall of one side of the docking concave plate 402, the limiting plate 405 is fixedly installed on the inner wall of the circular tube 302, the insertion pipe 406 is fixedly installed on the outer wall of one side of the fixed plate 401, and the injection hose 407 is slidably sleeved on the insertion pipe 406.

[0030] Specifically, pick up the fixed plate 401, align the docking concave plate 402 with the catheter 1, push the fixed plate 401, the fixed plate 401 drives the docking concave plate 402 to move, the docking concave plate 402 drives the drainage tube 404 to move and immerse in the circular tube 302, rotate the fixed plate 401, the fixed plate 401 drives the drainage tube 404 to rotate, when the drainage tube 404 is aligned with the limiting plate 405, push the fixed plate 401 again, the fixed plate 401 drives the docking concave plate 402 to completely immerse in the concave block 301, and insert the injection hose 407 on the insertion tube 406.

[0031] Furthermore, semicircular openings are evenly distributed on an outer wall of one side of the limiting plate 405 , and the semicircular openings are adapted to the drain pipe 404 .

[0032] Furthermore, a soft rubber pad is fixedly mounted on one side outer wall of the fixing plate 401, and the soft rubber pad is arranged in a ring shape.

[0033] The working principle of the utility model is:

[0034] First, insert the urinary catheter 1 into the patient's body, then pick up the concave block 301, align the round tube 302 with the urinary catheter 1, push the concave block 301, the concave block 301 drives the round tube 302 to move, the round tube 302, the round tube 302 moves and is inserted into the urinary catheter 1. When it is necessary to inject liquid into the urinary catheter 1, pick up the fixing plate 401, align the docking concave plate 402 with the urinary catheter 1, push the fixing plate 401, the fixing plate 401 drives the docking concave plate 402 to move, the docking concave plate 402 drives the drainage tube 404 to move and The fixed plate 401 is rotated, and the fixed plate 401 drives the drainage tube 404 to rotate. When the drainage tube 404 is aligned with the limit plate 405, the fixed plate 401 is pushed again, and the fixed plate 401 drives the docking concave plate 402 to be completely immersed in the concave block 301. The injection hose 407 is inserted on the insertion tube 406, and the liquid is injected into the docking concave plate 402 through the injection hose 407. The liquid enters the drainage tube 404 through the docking concave plate 402, and the liquid is injected into the circular tube 302 through the drainage tube 404. The liquid passes through the connecting plate 202 and lifts up the valve 205. The valve 205 is pushed and bent to unlock the round tube 302. The liquid passes through the round tube 302 and enters the round tube 302. The liquid enters the installation tube 206 through the round tube 302. The installation tube 206 injects the liquid into the flat rubber tube 207. The flat rubber tube 207 is squeezed and stretched open. The liquid enters the urinary catheter 1 through the flat rubber tube 207. When the injection is completed, the fixing plate 401 is pulled out to pull out the drainage tube 404. At this time, the injection is completed. When the residual liquid in the tube wall is gathered, The flat hose 207 blocks the liquid. Since the flat hose 207 has a flat shape, the liquid cannot push the flat hose 207 open and enter the circular tube 302. When too much liquid gathers, part of the liquid enters through the opening gap of the flat hose 207. At this time, the liquid is blocked by the valve 205. When the liquid pushes the valve 205, the valve 205 is blocked by the connecting plate 202 and does not bend, so it cannot form an opening to block the liquid. At this time, the blocking and reflux of the liquid are completed.

[0035] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
