[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] According to the following Figure 1-5 The utility model describes an annular elastic antibacterial skin patch for knee joint replacement and a storage device thereof.

[0026] On the one hand, if Figure 1 As shown, the utility model discloses an annular elastic antibacterial skin patch for knee replacement, including a patch main body layer 110. The patch main body layer 110 serves as a skin protection layer. The patch main body layer 110 is a cylindrical structure and is elastic. The patch main body layer 110 can be worn on the legs. The operation is as simple as a lady wearing stockings. The patch efficiency is improved, and preoperative preparation time can be saved. 1-2 doctors can complete the preoperative preparation work before the operation, saving the number of preoperative preparation personnel; saving materials (no need for stickers for the film, no overlap), and making the film smoother and better attached, which is beneficial to the operation.

[0027] In addition, the diameter of the cylindrical structure is close to the diameter of the leg, and a variety of diameters can be set so that a patch of the required diameter can be selected according to the patient's body shape; and the elasticity mentioned above is mainly to make the skin patch fit better to the leg.

[0028] like Figure 2 - Figure 4As shown, in order to facilitate the storage and wearing of the skin patch, the skin patch here can be curled outward with its own center as the center of the circle, so that the cylindrical structure forms a ring structure, which is similar to a condom after curling. On the one hand, the entire volume is reduced, which is convenient for packaging and storage. On the other hand, when wearing it, you only need to continuously push the ring body of the ring structure, making the entire wearing more convenient.

[0029] Preferably, the main layer 110 of the film is a polyethylene film to provide the required elasticity and to play a waterproof role.

[0030] Combination Figure 3 and Figure 4 As shown, in order to fix the film main layer 110 to the leg, an adhesive layer 130 is provided on the inner surface of the film main layer 110 , so that after wearing, the film main layer 110 can be adhered to the leg through the adhesive layer 130 .

[0031] Preferably, iodine is mixed into the adhesive of the adhesive layer 130 , so that after the adhesive layer 130 is bonded to the skin, the iodine can disinfect and sterilize the affected area, further preventing infection of the affected area.

[0032] like Figure 3 and Figure 4 As shown, when the cylindrical structure is curled into an annular structure, the internal adhesive layer 130 will be nutted to the outside, causing the adhesive layer 130 to lose its stickiness, so a protective film 120 is sleeved on the outer surface of the film main layer 110, so that when the skin film is curled from the inside to the outside, the inner surface of the adhesive layer 130 can fit the outer surface of the protective film 120, thereby ensuring the stickiness of the adhesive layer 130; after the leg film is finished, the protective film 120 can be directly torn off from the outside of the entire device, so one end of the protective film 120 is a flared part, which is convenient for tearing it off. Of course, the flared part can also be replaced by a component protruding from one end of the protective film 120, which can also be convenient for tearing it off.

[0033] In order to achieve the wearing of the film main layer 110, both ends of the film main layer 110 are set to open structures. After wearing, the opening structure at one end is located at the thigh root, and the opening structure at the other end is located at the ankle; an integrated foot membrane 111 is provided at the opening structure located at the ankle.

[0034] On the other hand, Figure 5The present invention also provides a storage device, including an annular elastic antibacterial skin patch for knee replacement and a bag body 210. The annular elastic antibacterial skin patch for knee replacement is located in the bag body 210, so that the annular elastic antibacterial skin patch for knee replacement can be stored. Preferably, a top cover 221 is bonded to one side of the bag body 210, and a protective tube 222 is provided on one surface of the top cover 221. The annular elastic antibacterial skin patch is located in the protective tube 222, so that the annular elastic antibacterial skin patch can be protected.

[0035] Optionally, the protective tube 222 is made of PVC or PE material.

[0036] Continue to refer to Figure 5 A limiting protrusion 223 is provided in the middle of the top cover 221 , and the limiting protrusion 223 extends into the center position of the annular structure to limit the movement of the annular structure in the protective tube 222 , thereby further protecting the annular elastic antibacterial skin film and preventing it from moving out of the protective tube 222 .

[0037] Preferably, a bag opening 211 is provided at one end of the bag body 210 , and a sealing line 212 is provided on the bag opening 211 , and the bag opening 211 can be conveniently removed through the sealing line 212 , so that the annular elastic antibacterial skin patch inside can be conveniently taken out.

[0038] The working principle and use process of the utility model are as follows: when in use, the bag opening 211 can be easily removed through the sealing line 212, so that the annular elastic antibacterial skin patch inside can be easily taken out, and then the annular elastic antibacterial skin patch is worn. When wearing, the foot is first inserted into the foot membrane 111, and then the annular elastic antibacterial skin patch is gradually stretched out by continuously pushing the ring of the annular structure, and during the stretching process, the adhesive layer 130 initially attached to the protective film 120 gradually separates from the protective film 120 and adheres to the skin, until the entire annular structure is completely stretched out and attached to the leg to form a cylindrical structure (composed of Figure 2 - Figure 1 process), and then tear off the external protective film 120.

[0039] In summary, the annular elastic antibacterial skin patch for knee replacement and its storage device, the patch main body layer 110 can be worn on the leg, and the operation is as simple as a lady wearing stockings, which improves the efficiency of patching and can save preoperative preparation time. 1-2 doctors can complete the preoperative preparation work before the operation, saving the number of preoperative preparation personnel; saving materials (no need for stickers for patching, no overlapping), and making the patch smoother and better attached, which is conducive to surgery; the skin patch can be curled outward with its own center as the center of the circle, so that the cylindrical structure forms an annular structure, which is similar to a condom after curling. On the one hand, the entire volume is reduced, which is convenient for packaging and storage. On the other hand, when wearing, it is only necessary to continuously push the ring body of the annular structure, making the entire wearing more convenient; a top cover 221 is bonded to one side of the bag body 210, and a protective tube 222 is provided on one surface of the top cover 221.
