Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] See Figures 1 to 5 As shown, a drainage tube anti-detachment fixing device includes an application mechanism and a fixing mechanism. The application mechanism includes an application patch 1, an installation hole 2 and an insertion groove 3 located in the middle of the upper side of the application patch 1, a positioning clip 4 located in the middle of the lower side of the application patch 1, a sliding groove 5 located on the lower side of the positioning clip 4, a movable clip 6 slidably installed inside the sliding groove 5, a pressure sensor 7 located at the lower end of the sliding groove 5, and a controller 8 located at the side end of the sliding groove 5. The fixing mechanism includes a fixing clip 9 installed on the installation hole 2, a sliding groove 10 equidistantly circumferentially arranged on the fixing clip 9, a locking block 11 slidably installed inside the sliding groove 10, a limiting rod 12 installed on the upper end of the locking block 11, and an adjusting screw sleeve 13 rotatably installed on the upper end of the fixing clip 9.

[0023] The patch 1 is made of a transparent material, allowing observation of the adhered area; the adhesive surface of the patch 1 is provided with transparent release paper. This isolates the adhesive surface when not in use, preventing external dust from adhering to the adhesive surface and affecting its use.

[0024] The positioning clamp 4 and the moving clamp 6 have the same clamping end structure, both including a fixed ring 41, clamping springs 42 symmetrically arranged on both sides of the inner wall of the fixed ring 41, and an arc-shaped clamping block 43 installed at the end of the clamping spring 42. By deforming the clamping spring 42, the device can adapt to drainage tubes of different sizes.

[0025] Both the fixing clip 9 and the adjusting screw sleeve 13 are provided with notches 91 that are adapted to the insertion groove 3. The notches 91 of the fixing clip 9 are connected to the insertion groove 3. This allows the device to be quickly installed onto the drainage tube through the insertion groove 3 and the notches 91, and the device is tightly connected to the patient's skin through the adhesive surface of the dressing 1, thus achieving rapid installation of the device onto the drainage tube.

[0026] The upper outer wall of the fixing clamp 9 is provided with an external thread that matches the adjusting screw sleeve 13; the upper surface of the adjusting screw sleeve 13 is provided with several arc-shaped grooves 131 equidistantly arranged around its circumference, and the limiting rod 12 is slidably installed inside the arc-shaped grooves 131; the limiting rod 12 is provided with a limiting baffle 121. By rotating the adjusting screw sleeve 13, the limiting rod 12 is driven to move on the arc-shaped grooves 131, thereby pushing out the locking block 11 to clamp the drainage tube. The threaded connection forms a self-locking mechanism, which can quickly clamp or loosen the drainage tube and fix it.

[0027] The controller 8 includes a control board, control keys, a battery, a central processing unit (CPU), and a buzzer mounted on the control board. The pressure sensor 7, control keys, battery, and buzzer are all electrically connected to the CPU. The CPU uses a PLC control board and has preset pressure thresholds. The battery is a button cell battery, reducing space occupation and cost. It can judge the traction strength through feedback from the pressure sensor, but when the traction force exceeds the threshold, the buzzer sounds an alarm, prompting medical personnel to adjust the patient's position or tubing to reduce the risk of tube dislodgement.

[0028] Example 2

[0029] Working principle: When using this device, first select the best insertion position according to the location of the drainage tube (that is, the position where the notch 91 of the fixing clip 9 and the adjusting screw sleeve 13 can be inserted into the drainage tube). Then, attach the fixing clip 9 and the adjusting screw sleeve 13 to the drainage tube (at this time, rotate the adjusting screw sleeve 13 so that the notch of the adjusting screw sleeve 13 is collinear with the notch of the fixing clip 9). Then, move the device until the dressing 1 is close to the patient's skin (at this time, the fixing clip 9 and the adjusting screw sleeve 13 are movably sleeved on the drainage tube). Then, peel off the transparent release paper and stick the dressing 1 to the patient's skin (when applying the dressing, ensure that the drainage tube is located in the center of the mounting hole 2 and will not be pulled). Then, rotate the adjusting screw sleeve 13. Under the action of the arc groove 131, the limiting rod 12 is driven to... The arc-shaped groove 131 moves inside, thereby causing the locking block 11 to extend or retract, clamping or releasing the drainage tube (at this time, the notch 91 of the adjusting screw sleeve 13 and the notch 91 of the fixing clamp 9 are not collinear, to prevent the drainage tube from coming out of the notch 91). After clamping the drainage tube, the external drainage tube is inserted into the positioning clamp 4 and the moving clamp 6 in an S-shaped bend, and the controller 8 is activated. When the patient pulls on the drainage tube, the drainage tube pulls the moving clamp 6 to move downward along the sliding groove 5. When the moving clamp 6 moves down and squeezes the pressure sensor 7, the buzzer sounds an alarm (at this time, the pressure on the pressure sensor 7 is greater than the set threshold), prompting medical staff to adjust the patient's position or the tube to reduce the risk of the drainage tube being pulled out.
