Technical Field

[0001] The invention relates to the technical field of medical devices, and more specifically to a device for preventing blood seepage in a kidney dialysis device access. Background Art

[0002] Renal dialysis equipment generally includes dialysis fluid, dialyzer, pressure pipeline, pipeline, microcomputer, pipette pipeline, etc., so that when the patient undergoes renal dialysis, the pipeline pathway constructed needs to be combined with a special anti-bleeding device to maintain sealing, to prevent blood loss caused by blood being drawn out during dialysis and blood generated during treatment from penetrating from the edge area, thereby effectively improving the stability of the use of renal dialysis equipment and the safety factor of treatment; In summary, the inventors have found that the existing access blood seepage prevention devices mainly have the following defects: since the duration of renal dialysis treatment for patients is generally four hours or more, the patients are easily agitated due to the unconsciousness and discomfort during dialysis, and are prone to pulling the access and the blood seepage prevention device, which increases the risk during dialysis and easily causes the access and the equipment to separate. As a result, the structure of the current blood seepage prevention device is relatively simple and cannot stably fix the patient's dialysis position and the access, which may cause the through-tube joint to fall off when the patient struggles, resulting in secondary blood seepage, thereby reducing the use intensity of the current blood seepage prevention device.

[0041] Specific functions and operation procedures of this embodiment: In the present invention, the blood seepage prevention device of the kidney dialysis equipment access can stably install the sealed metal tube 2 and the blood circulation tube 3 in the kidney dialysis equipment through the fixed structure 1, and then the blood circulation tube 3 can be combined with the sealed metal tube 2 for reinforcement and covering, so as to prevent blood from being lost through penetration, and then the blood circulation tube 3 can use the bottom puncture needle 4 to puncture the patient's dialysis area, and finally use the reinforcer 5 to fix the puncture area, so as to effectively improve the connection firmness with the patient and the kidney dialysis equipment, and avoid the anti-blood seepage device automatically falling off due to the restlessness of the patient during the dialysis time too long, which affects the dialysis safety factor and increases the expansion of the patient's wound, and then the solid block 12 of the fixed structure 1 is firstly through the four corner restraint blocks 11 The two anti-slip rings 13 are installed in parallel in the connection area of ​​the kidney dialysis equipment, and the dividing block 14 in the middle is centrally positioned so that the dividing block 14 can separate the two groups of anti-slip rings 13 to achieve the process of circulating drainage to the internal treatment of the equipment, and then the positioning frame 15 and the fixing plug-in 16 carried by the surface of the solid block 12 can further improve the connection firmness effect between the overall device and the kidney dialysis equipment. The overall structures of the two groups of anti-slip rings 13 are consistent, so that the No. 1 ring body 132 and the No. 2 ring body 133 of the anti-slip ring 13 can be assembled through the support column 134 at the edge, and then the No. 2 ring body 133 can use the top locking bolt 135 to complete the connection with the top of the support column 134. For this reason, after the No. 1 ring body 132 is connected to the surface of the solid block 12, the No. 2 ring body 1 33 can be combined with the locking bolt 135 and the drainage area of ​​the device for precise fixation. At the same time, the two use the penetration groove 131 in the center area to allow the blood circulation tube 3 in the sealed metal tube 2 to penetrate, ensuring that the blood circulation tube 3 can input blood into the device at a precise position, avoiding blood infiltration and loss caused by position deviation, and further improving the use strength of the overall anti-blood seepage device. Then, the ring 1322 of the No. 1 ring body 132 and the No. 2 ring body 133 can use the internal limit ring 1323 to contact the edge of the sealed metal tube 2, and then the control block 1326 set on the outside of the ring can allow the straight rod 1327 to penetrate the edge of the ring 1322 and the limit ring 1323, so that the arc block of the clamping piece 1328 set inside the penetration groove 131 3282 can be pushed by the straight rod 1327 to move. Therefore, when the control block 1326 pushes the straight rod 1327 in, the adsorbent 3281 at the bottom of the arc block 3282 can be displaced. Therefore, the edge of the sealing metal tube 2 is adsorbed and fixed to achieve a stable connection effect.
