During this process, the correct placement and stable fixation of the drainage tube are crucial. To secure the drainage tube, a fixator is required.

[0003] Existing abdominal drainage fixators generally only fix the drainage tube to the patient's legs. The drainage tube between the patient's legs and the abdominal cavity is in a fixed state, which can play a certain role in preventing pulling. However, the patient's legs are prone to press on the drainage tube when moving, thereby affecting its normal drainage. When the drainage tube is loose, it is difficult for people to discover and re-fix it in time. In view of the above problems, the existing equipment needs to be improved. Summary of the Invention

[0004] The object of the present invention is to provide an adjustable abdominal drainage fixer to solve the problem that the existing abdominal drainage fixer proposed in the above background technology generally only fixes the drainage tube to the patient's leg. The drainage tube between the patient's leg and the abdominal cavity is in a fixed state, which can play a certain role in preventing pulling. However, the patient's legs are prone to press on the drainage tube during movement, thereby affecting its normal drainage. When the drainage tube becomes loose, it is difficult for people to discover and re-fix it in time.

After the trigger button 20 is pressed, the alarm 26 automatically triggers the alarm, which facilitates the effect of prompting that the guide tube is loose.

[0029] The use method and advantages of the present invention: The adjustable abdominal drainage fixator works as follows: like Figures 1 to 5 As shown: first, pass the drainage tube through the fixed cylinder 29 and the second through hole 28 and extend it into the support frame 1, pass the drainage tube between the second fixed guide rod 14 and the friction wheel 18, and then pass the drainage tube in an "S" shape around all the movable guide rods 13, then pass the drainage tube between the two first fixed guide rods 8 and out of the first through hole 7, then install the transparent cover 33 with bolts 34, connect the head end of the drainage tube to the patient's abdominal cavity, connect the end of the drainage tube to the drainage bag, use the first strap 3 and the second strap 5 to tie the support frame 1 to the patient's legs, and the cushion 2 fits the patient's skin to play a role of cushioning, and then use the third strap 30 to fix the drainage tube. The section of the drainage tube connected to the patient's abdominal cavity is in a fixed state, and the drainage tube in the support frame 1 can be extended and stored. When the patient's legs move, the drainage tube in the support frame 1 is pulled, and the movable guide rod 1 3 and the slider 11 slide, and when the patient's legs return to their original position, the movable guide rod 13 and the slider 11 automatically stretch out the drainage tube, which is convenient for automatic storage, preventing the drainage tube from being forcibly pulled and causing it to be separated from the patient's abdominal cavity, and preventing the drainage tube from being pressed by the patient's legs when moving. When the drainage tube at the fixing cylinder 29 becomes loose, the movement of the drainage tube drives the friction wheel 18 to rotate, and the extrusion shaft 16 rotates and squeezes and presses the trigger button 20, thereby triggering the alarm 26 to automatically alarm, conveniently achieving the effect of loose prompting, and the card block 23 automatically snaps into the card slot 21 to lock the trigger button 20, thereby continuing the alarm. After the medical staff re-fixes the drainage tube, they pull the pull ring 25 again. The card block 23 moves and leaves the card slot 21 under the pulling action of the connecting rope 24, thereby unlocking the trigger button 20, and the trigger button 20 automatically pops open, thereby releasing the alarm.

[0030] In summary, the adjustable abdominal drainage fixator achieves the purpose of telescopic adjustment, automatic storage and pressure prevention, and loosening prompt, meeting people's usage needs.
