A fixed pin 10, the inner wall of the fixed head 6 is provided with a pressure spring 16, the inner wall of the fixed head 6 is fixedly installed with a fixing port 14, the outer wall of the fixed head 6 is movably connected with a fixing patch 12, the outer wall of the fixing patch 12 is provided with a fixing component 11, the outer wall of the fixing patch 12 is fixedly installed with a puncture needle 13, and the inner wall of the fixed head 6 is provided with a flow tube 15. In the above structure, the inner wall of the slot 4 is adapted to the shape of the plug block 3, and the plug block 3 is inserted into the interior of the slot 4 by inserting the plug block 3 from the top of the slot 4.

[0025] In a preferred embodiment, the fixing component 11 includes a fixing block 1101, an outer edge of the fixing block 1101 is provided with an inclined groove 1102, an outer wall of the fixing block 1101 is provided with a fixed circular groove 1103, and a flow groove 1104 is provided on the side of the fixing block 1101 close to the inclined groove 1102. In the above structure, the number of the inclined groove 1102 and the fixed circular groove 1103 is two, and the two inclined grooves 1102 and the fixed circular grooves 1103 are symmetrically distributed on both sides of the fixing block 1101. The fixing component 11 is fixed as a whole by connecting the fixed circular groove 1103 with the fixing pin 10.

[0026] In a preferred embodiment, a bevel is provided at the top of the fixed circular groove 1103, and a bevel is provided at the bottom of the fixed pin 10, and the bevel at the top of the fixed circular groove 1103 is adapted to the bevel at the bottom of the fixed pin 10. In the above structure, when the fixed block 1101 is located inside the fixed head 6, the fixed pin 10 is located inside the fixed circular groove 1103. By pulling the fixed block 1101 outward, the bevel at the top of the fixed circular groove 1103 and the bevel at the bottom of the fixed pin 10 form an upward pressure on the fixed pin 10, so that the fixed pin 10 moves toward the inner wall of the fixed head 6.

[0027] In a preferred embodiment, the non-fixed end of the strap 2 extends to the inside of the plug block 3, and the non-extended end of the strap 2 is fixedly connected to the rotating shaft 8. In the above structure, the strap 2 can be rolled up to the inside of the plug block 3 through the rotating shaft 8.

[0028] In a preferred embodiment, an extension column is provided at the top of the rotating shaft 8, and the extension column is located at the center of the clockwork spring 9. The extension column at the top of the rotating shaft 8 overlaps with one end of the clockwork spring 9, and the other end of the clockwork spring 9 overlaps with the inner wall of the plug block 3. In the above structure, the strap 2 is extended by pulling the plug block 3, and the rotating shaft 8 is driven to rotate by the extension of the strap 2. When the rotating shaft 8 rotates, one end of the clockwork spring 9 is driven by the rotating shaft 8, so that the shape of the clockwork spring 9 changes. At this time, the plug block 3 is released, and the clockwork spring 9 recovers and pulls the rotating shaft 8 to reel in the strap 2, thereby pulling the plug block 3 back to its original position.

[0029] In a preferred embodiment, an extension ring is provided at the top of the fixing pin 10, and the extension ring is larger than the opening of the fixing head 6 close to the fixing pin 10. In the above structure, the fixing pin 10 is fixed inside the fixing head 6 by the extension ring at the top of the fixing pin 10, so that the fixing pin 10 cannot be detached from the fixing head 6.

[0030] Working principle: when using the device, the storage bag 1 is placed on the user's abdomen, and the plug block 3 is pulled to extend the strap 2, and the extension of the strap 2 drives the rotating shaft 8 to rotate. When the rotating shaft 8 rotates, one end of the spring 9 is driven by the rotating shaft 8, so that the shape of the spring 9 changes, and the plug block 3 is placed inside the slot 4, and then the strap 2 is straightened by the rewinding of the spring 9 to fit the user's back. At this time, the fixing head 6 is picked up and inserted into the user's wound through the puncture needle 13, so that it adheres to the user's skin through the fixing patch 12. At this time, the installation of the device is completed. When the user exudes body fluids, the body fluids enter the interior of the flow tube 15 through the puncture needle 13 and the fixing component 11, and then enter the interior of the diversion tube 5 through the flow tube 15, and then enter the interior of the diversion tube 5 through the diversion tube 5. After entering the interior of the storage bag 1, it can be discharged through the liquid outlet 7. When the puncture needle 13 and the fixing patch 12 need to be replaced, the fixing block 1101 is pulled outward so that the bevel angle at the top of the fixing circular groove 1103 and the bevel angle at the bottom of the fixing pin 10 form an upward pressure on the fixing pin 10, so that the fixing pin 10 moves toward the inner wall of the fixing head 6. When the fixing pin 10 completely enters the interior of the fixing head 6, the fixing component 11 is taken out, and a new fixing patch 12 is taken out. The inclined groove 1102 above the fixing component 11 outside the fixing patch 12 is aligned with the fixing pin 10 and inserted into the interior of the fixing head 6. The fixing pin 10 is pressed upward by the slope of the inclined groove 1102. When the fixing circular groove 1103 reaches the bottom of the fixing pin 10, the pressure spring 16 pops out the fixing pin 10 to fix it.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
