Description

Technical Field

[0001] The utility model relates to the technical field of external patches, and more specifically, to a breathable external patch for periarthritis of shoulder. Background Art

[0002] The frozen shoulder patch is a plaster composed of a backing layer, a medical resin, a main layer and a medical non-woven fabric, and is applied on a medical tape substrate.

[0003] The frozen shoulder patch is applied topically, on acupoints and as an ointment. It can soften and disperse lumps, relax muscles and tendons, dispel cold and relieve pain, and has the therapeutic effect of relieving pain.

[0004] In the prior art, a patent document with publication number CN210698270U discloses an external patch for treating scapulohumeral periarthritis, comprising a non-woven fabric backing layer, a release paper cover lining, a button battery and a PLC, wherein a fixing layer is fixedly installed at the bottom of the non-woven fabric backing layer by gluing, and a micro-vibration motor is fixedly installed at the center between the fixing layer and the non-woven fabric backing layer by gluing. The fixing layer and proximity sensor provided in the external patch enable people with different absorption rates to know the absorption status of the ointment in time, thereby preventing people with fast absorption from having ineffective application time, and preventing people with slow absorption from removing the ointment before completely absorbing the medicine, thereby causing waste. However, the above device is not convenient for effectively adjusting the adhesion between the ointment and the human skin, the thermal solubility and the volatilization efficiency of the ointment by means of airbag pressure control and heat control, and is therefore not convenient for controlling the absorption efficiency of the ointment by the human body. Based on this, the utility model provides a breathable scapulohumeral periarthritis external patch to solve the technical problems raised in the above background technology. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the utility model provides a breathable shoulder periarthritis external patch, which has the advantages of controlling the expansion amplitude of the pressure bag, effectively controlling the tightness of the ointment and human skin, and then controlling the volatilization efficiency of the ointment and the absorption rate of the ointment by the human skin.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a breathable shoulder periarthritis external patch, comprising an inner patch and an outer patch, the bottom surface of the inner patch is provided with an adhesive area, the inner patch and the outer patch are bonded together, the center positions of the inner patch and the outer patch are provided with medicine holes, the top surface of the inner patch is bonded with an elastic base cloth, the bottom surface of the elastic base cloth is connected with an ointment layer, a pressure bag is provided above the elastic base cloth, an air cavity is fixedly provided inside the pressure bag, an oxidation heating layer is provided in the air cavity, the surface of the air cavity is respectively connected with a one-way air inlet nozzle and an air control component, the peripheral side surface of the pressure bag is fixedly installed with a connecting cloth, and the connecting cloth is bonded together with the outer patch.

[0007] As a preferred technical solution of the utility model, the inner patch, the outer patch and the connecting cloth are all breathable mesh cloths, and the elastic base cloth is an elastic yarn belt.

[0008] As a preferred technical solution of the utility model, the top surfaces of the inner patch and the outer patch are fixedly provided with Velcro hook surfaces, and the outer patch, the bottom surface of the connecting cloth and the upper end of the elastic base cloth are fixedly provided with Velcro fleece surfaces that cooperate with the Velcro hook surfaces.

[0009] As a preferred technical solution of the utility model, the air control component includes an air pipe connected to the air cavity, the inner wall of the air pipe is slidably connected to an air-blocking plug, the surface of the air-blocking plug is fixedly mounted with a T-shaped pressure rod slidably connected to the air pipe, and the T-shaped pressure rod is provided with a spring at a position corresponding to the outside of the air pipe.

[0010] As a preferred technical solution of the utility model, the outer edge of the medicine hole on the inner patch and the outer edge of the inner patch are both installed with water-stop ring strips, and the water-stop ring strips swell when exposed to water. The water-stop ring strips are composed of rubber and blister particles.

[0011] As a preferred technical solution of the utility model, the pressure bag is made of silicone material, and the inside of the ointment layer is filled with medicine for treating scapulohumeral periarthritis.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] When the utility model is not in use, the elastic base fabric is fully contracted and the ointment does not contact the human skin. When the external patch needs to be used, the inner patch is fixed on the shoulder of the human body. When the ointment needs to be volatilized, the user presses the pressure bag back and forth, and then drives the elastic base fabric to stretch outward step by step, and the external air gradually enters the interior of the air cavity to make the oxidation heating layer generate heat. By controlling the expansion amplitude of the pressure bag, the tightness of the ointment to the human skin can be effectively controlled, and then the efficacy volatilization efficiency of the ointment and the absorption rate of the ointment by the human skin can be controlled. By filling and deflating the air cavity, the heating effect of the oxidation heating layer can be effectively controlled, and then the thermal melting effect of the ointment and the absorption rate of the ointment by the human skin can be assisted. When it is necessary to block the therapeutic operation of the ointment in a certain period of time or in a certain scene, the ointment can be separated from the human skin by quickly deflating the air cavity. In addition, the ventilation effect of the external patch can be effectively improved by setting the breathable mesh cloth of the inner patch, the outer patch and the connecting cloth.

[0021] By setting the water stop strip, the probability of external liquid and internal ointment entering the adhesive area 3 is effectively reduced, thereby maintaining the high adhesion of the adhesive area 3;

[0022] The top surface of the inner patch 1 is bonded with an elastic base fabric 5, the bottom surface of the elastic base fabric 5 is connected with an ointment layer 6, and the inside of the ointment layer 6 is filled with a scapulohumeral periarthritis treatment drug;

[0023] A pressure bag 7 is arranged above the elastic base fabric 5, and the pressure bag 7 is made of silica gel;

[0024] An air cavity 8 is fixedly opened inside the pressure bag 7, and an oxidation heating layer 9 is arranged inside the air cavity 8;

[0025] The oxidation heating layer 9 is a mixture of iron powder, activated carbon, vermiculite, inorganic salt and water;

[0026] When the external patch is not in use, the air cavity 8 is in a negative pressure state, and the oxidation heating layer 9 does not generate heat due to lack of air;

[0027] The surface of the air cavity 8 is respectively connected with a one-way air inlet nozzle 10 and an air control component;

[0028] By setting the one-way air inlet nozzle 10, external air can enter the interior of the air cavity 8 in one direction through the one-way air inlet nozzle 10;

[0029] By setting the gas control part, the gas in the gas cavity 8 can be discharged to the outside;

[0030] The air control part includes an air pipe 12 connected to the air cavity 8, an air-blocking plug 13 is slidably connected to the inner wall of the air pipe 12, a T-shaped pressure rod 14 slidably connected to the air pipe 12 is fixedly installed on the surface of the air-blocking plug 13, and a spring 15 is sleeved on the T-shaped pressure rod 14 at a position corresponding to the outer side of the air pipe 12;

[0031] When the T-shaped pressure rod 14 is not under pressure, the air-blocking plug 13 seals the air tube 12. When the gas in the air cavity 8 needs to be discharged, the T-shaped pressure rod 14 is pressed to discharge the gas in the air cavity 8.
