Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically to a knee joint external dressing. Background Technology

[0002] External application of traditional Chinese medicine is a type of external treatment method in traditional Chinese medicine. It has fewer side effects, can treat a variety of diseases, is safe to use, and is easy to operate. Many diseases can be treated or treated with this method. The operation method is as follows: medicine is filled into the external application pack, heated and then sealed and placed on the patient's body surface to allow the medicinal ingredients to better penetrate the skin and improve the efficacy. Therefore, this knee joint external application pack needs to be used in the treatment of knee joint.

[0003] For example, a traditional Chinese medicine external application pack, as disclosed in patent publication number CN215025149U, includes a storage bag for holding the dressing. The storage bag has metal supports on its upper and lower sides, which are fixedly connected to the bag. The storage bag has absorbent components on its four sides, an opening on one side for easy dressing replacement, and a heating device on the top, detachably connected to the bag. The metal supports fix the sides of the storage bag, effectively preventing the external application pack from moving or slipping. Furthermore, the metal supports on both sides of the storage bag increase the contact area with the abdomen, increasing patient comfort and meeting the requirements for prolonged external application. The absorbent components absorb moisture released from the Glauber's salt during application, preventing water from soaking the dressing bag, clothing, and bed. The heating device heats the dressing for better therapeutic effect.

[0004] However, during the use of the above-mentioned devices, due to the design of their internal storage bags, the shape of the human body parts varies, which can easily cause the medicine to flow back and accumulate in the corners when applied externally, reducing the medical effect. Therefore, we propose a more convenient and practical external application pack to meet the usage needs. Utility Model Content

[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In the treatment of knee joint diseases, external dressings are required. The external dressing provided by this utility model is specifically designed for the treatment of complex knee joint diseases. When using this device for treatment, it is important to note that the knee joint and surrounding skin should be cleaned before use to avoid dirt affecting the absorption of medication and the therapeutic effect. The temperature should be tested before use to ensure that it will not cause burns or other damage to the skin. Before wearing, the tightness of the connecting strap 101 should be adjusted according to the individual's leg circumference to avoid excessive tightness that may obstruct blood circulation. The usage time should be arranged reasonably according to the instructions or doctor's advice, and it should not be used for longer than the prescribed time to avoid skin irritation or other discomfort.

[0021] like Figure 1-Figure 3 As shown, this utility model provides a technical solution: a knee joint external dressing pack, including a connecting mechanism 1, the connecting mechanism 1 including a connecting strap 101, a sponge pad 102 fixedly connected to one side of the connecting strap 101, an external dressing mechanism 2 provided on one side of the connecting mechanism 1, the external dressing mechanism 2 including an external dressing frame 201, a through hole opened on one side of the top of the external dressing frame 201, a medicine inlet tube 203 fixedly connected in the through hole, a return tube 205 fixedly connected to one end of the medicine inlet tube 203, a clamping block 206 fixedly connected to the inner wall of one end of the return tube 205, a fixing plate 207 fixedly connected to the other end, and a ball bearing 208 rotatably connected to the inner wall of the middle part of the return tube 205.

[0022] like Figure 2As shown, a connecting frame 103 is fixedly connected to one side of the connecting strip 101. Multiple equidistant through holes are opened on one side of the connecting frame 103. Multiple graphite rods 104 are electrically connected in the through holes. Through holes are symmetrically opened on one side of the connecting frame 103. A ventilation pipe 105 is fixedly connected in the through holes. A fan 106 is installed in the ventilation pipe 105. An adsorption plate 107 is fixedly connected to one side of the connecting strip 101. A sliding groove 108 is opened on one side of the adsorption plate 107. Velcro 109 is fixedly connected to both sides of the connecting strip 101.

[0023] It is important to note that during use, the external application mechanism 2 is first inserted into the suction plate 107 through the sliding groove 108. Then, it is fixed to the patient's knee joint by the Velcro 109 under the action of the connecting strap 101 and the sponge pad 102. At the same time, the graphite rod 104 on the connecting frame 103 is heated. During this process, the fan 106 in the ventilation pipe 105 is activated to blow the heat generated by the graphite rod 104 onto the patient's skin. The connecting mechanism 1 can be adjusted according to the leg circumference of different users, so that the knee joint external application pack can better fit people of different body types, enhance applicability, and ensure that the external application pack will not loosen or slip during use, providing stable support. It should be noted that the suction plate 107 is made of cotton, polyester or other synthetic fibers. As a soft material that comes into direct contact with the skin, it is breathable. While absorbing the medicine, it fits tightly with the knee and, under pressure, brings the medicine into contact with the skin, similar to the principle of a band-aid.

[0024] like Figure 3 As shown, sliding protrusions 202 are fixedly connected to both sides of the external application frame 201. The sliding protrusions 202 are adapted to the sliding groove 108. The external application mechanism 2 is inserted into the adsorption plate 107. One end of the drug inlet tube 203 is screwed with a drug inlet funnel 204, and one end of the return tube 205 is fixedly connected with a drug storage tube 209.

[0025] It is important to note that during use, the external application frame 201 is first inserted into the adsorption plate 107 by sliding the protrusion 202. Then, the drug inlet funnel 204 and the drug inlet tube 203 are manually connected, and the medicine is added into the return tube 205. During this process, the ball bearing 208 is connected to the fixing plate 207 to add the medicine into the storage tube 209. The drug inlet funnel 204 is then removed. During the return flow, the ball bearing 208 is sealed by the clamping block 206 under pressure to prevent backflow. The external application mechanism 2 reduces environmental contamination of the medicine and ensures the safety and hygiene of the use process. It is important to note that the storage tube 209 is made of special materials such as breathable membrane, microporous membrane and non-woven fabric. It is breathable and allows a small amount of medicine to pass through. The medicine is blown out by the fan 106, but the medicine does not leak.

[0026] Working principle: During use, the external application mechanism 2 is first inserted into the adsorption plate 107 via the sliding protrusion 202 and sliding groove 108. Then, the drug inlet funnel 204 and drug inlet tube 203 are manually connected, and the medicine is added into the return tube 205. During this process, the ball bearing 208 is connected to the fixing plate 207 to add the medicine into the storage tube 209. The drug inlet funnel 204 is then removed. During the return flow, the ball bearing 208 is sealed by the clamping block 206 under pressure. Finally, the Velcro 109 is fixed to the patient's knee joint by the connecting strap 101 and the sponge pad 102. At the same time, the graphite rod 104 on the connecting frame 103 is heated. During this process, the fan 106 in the ventilation tube 105 is activated to heat the graphite rod 104. The medication in the reservoir tube 209 is blown onto the patient's skin. This device enables precise drug delivery and prevents backflow, allowing the medication to be evenly distributed to the treatment area and improving the treatment effect. When the reservoir tube 209 needs to be cleaned, the cleaning agent is added to the return tube 205 through the inlet funnel 204 and the inlet tube 203, and then enters the reservoir tube 209 under the action of the ball bearing 208 and the fixing plate 207 to clean the reservoir tube 209. After cleaning, the inlet funnel 204 is removed from the inlet tube 203. Then, the ball bearing 208 and the clamping block 206 are moved to the fixing plate 207 for contact by a support such as a wooden stick, and the cleaning solution is poured out of the reservoir tube 209 under the action of gravity. This operation is repeated until the cleaning of the reservoir tube 209 is completed.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the accompanying embodiments and their equivalents.
