[0035] Please refer to Figures 1-10 This utility model embodiment provides a pressure-free dressing, including a fixing plate 2, a fixing tape 1 is pasted on one side of the fixing plate 2, and a sleeve 9 is fixedly connected to the other side. An air bladder 5 is provided inside the sleeve 9. An installation ring 3 is fixedly connected to one end of the sleeve 9, and a fixing ring 4 is fastened to the installation ring 3. The medicated patch is fixed between the installation ring 3 and the fixing ring 4.

[0036] A limiting adhesive part 21 is provided on the outer edge of the fixing plate 2, and the fixing tape 1 is attached to the limiting adhesive part 21.

[0037] The fixing plate 2 is reusable, and the fixing tape 1 is replaceable. The fixing tape 1 is fixed to the fixing plate 2 by adhering to the limiting adhesive part 21. By sticking the fixing tape 1 around the application site, the entire application can be fixed without the user having to hold it in place, thus improving the convenience of use. The limiting adhesive part 21 can improve the accuracy of the connection between the fixing tape 1 and the fixing plate 2, and avoid misalignment of the drug delivery due to the misalignment of the connection position.

[0038] A baffle 10 is fixedly connected inside the sleeve 9, and the upper end of the airbag 5 is fixedly connected to the baffle 10.

[0039] By setting the sleeve 9, a certain height difference can be made between the fixing tape 1 and the medicated patch. When the fixing tape 1 is pasted on the skin, the medicated patch is subjected to pressure and comes into contact with the affected area, so as to achieve drug delivery without pressure.

[0040] A clamping block 8 is fixedly connected to the surface of the fixing plate 2. A hose 7 is clamped on the clamping block 8. A rubber pressure ball 6 is fixedly connected to one end of the hose 7, and the other end is fixedly connected to the airbag 5.

[0041] The upper part of the airbag 5 is fixedly connected to the entire plane of the baffle 10. One end of the airbag 5 is also provided with an air outlet and a sealing plug to facilitate air intake and deflation. The lower part of the airbag 5 is in contact with the medicated patch. By pressing the rubber pressure ball 6, air enters the airbag 5 from the hose 7, causing the lower part of the airbag 5 to inflate, thereby pressing the medicated patch to ensure that the medicated patch is always in contact with the wound. The pressure can be adjusted by adjusting the air intake to avoid excessive or insufficient pressure, thereby improving the pressure and treatment effect. The clamp 8 limits the hose 7 to prevent the rubber pressure ball 6 from shaking.

[0042] A hinge rod 43 is fixedly connected to one end of the fixing ring 4. The hinge rod 43 is rotatably connected to the mounting ring 3. A locking block 41 is fixedly connected to the end of the fixing ring 4 away from the hinge rod 43. A locking groove 31 is provided on the mounting ring 3. The locking block 41 is locked into the locking groove 31. Several insertion holes 32 are provided on the mounting ring 3. Several insertion rods 42 are fixedly connected to the fixing ring 4. Each insertion rod 42 is inserted into the corresponding insertion hole 32.

[0043] The fixing ring 4 is hinged to the mounting ring 3 via the hinge rod 43. In use, the medicated patch is placed on the mounting ring 3, with the edge of the medicated patch covering several insertion holes 32. Then, the fixing ring 4 is rotated to lock the locking block 41 into the locking groove 31. At the same time, the insertion rod 42 brings part of the edge of the medicated patch into the insertion hole 32 for fixation, thus achieving overall fixation of the medicated patch. This setting facilitates the installation and subsequent replacement of the medicated patch. The operation is simple, and each time it is used, only the fixing tape 1 and the medicated patch need to be replaced. Other parts can be reused after disinfection, reducing usage costs and minimizing material waste.

[0044] In summary, the working principle of this utility model embodiment of a pressure-free application patch is as follows:

[0045] In use, the fixing tape 1 is precisely attached to the fixing plate 2 along the limiting adhesive part 21. The medicated patch is placed on the mounting ring 3, with the edge of the medicated patch covering several insertion holes 32. Then, the fixing ring 4 is rotated to lock the locking block 41 into the locking groove 31. At the same time, the insertion rod 42 brings part of the edge of the medicated patch into the insertion hole 32 for fixation, thus achieving overall fixation of the medicated patch. Then, the medicated patch is applied to the wound surface, and the fixing tape 1 is attached to the skin around the wound surface. Then, the rubber pressure ball 6 is pressed to allow air to enter the air bladder 5 from the tubing 7, causing the lower part of the air bladder 5 to inflate and press on the medicated patch, ensuring that the medicated patch is always in contact with the wound surface, improving the pressure and treatment effect.

[0046] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
