Description

Disposable none elastic strain pressurizing dressing Technical Field The invention relates to the technical field of medical bandaging, in particular to a disposable sterile elastic pressurizing bandaging dressing. Background After fat plastic surgery (such as lumbar and abdominal aspiration, thigh aspiration, upper arm aspiration, calf aspiration, etc.), a certain amount of swelling fluid, tissue fluid and blood will remain under the skin of the patient, and the subcutaneous fat layer wound cavity is in a loose state. If the liquid exuded from the wound cannot be effectively adsorbed after operation, the incision is possibly polluted, healing is delayed or infection is possibly caused, and the patient is uncomfortable or cold is caused by long-term wetting of the skin in a large area. If the elastic pressure is not properly flattened after the lipoplasty, the complications such as local hematoma, edema, seroma, uneven skin, poor morphology, pigmentation, skin necrosis and the like can be caused, and the operation effect and the recovery of a patient are seriously affected. After orthopedic surgery (e.g., reduction of bone fracture, internal fixation of bone fracture, joint surgery) and trunk surgery (e.g., angioplasty, caesarean section), the wound may have a certain amount of interstitial fluid and blood exuding. The long-term dressing can increase skin perspiration, and if effective moisture absorption and ventilation treatment is not performed, the wound can be polluted, and the wound healing is delayed and even infected. The affected limb or body after operation needs a period of time to be wrapped and fixed by braking to help the tissue of the affected part to repair and heal, if effective wrapping, braking and fixing cannot be achieved, the operation effect and the recovery speed of a patient can be affected, and even serious consequences such as fracture nonunion are caused. At present, most of the common body shaping clothes or compression binding products in clinic are elastic cloth finished products produced in batch in factories, and the following technical defects exist: (1) The sanitary safety problem is that the allergen (such as chemical dye, lubricating oil, dust, viscose, etc.) remained in the production and processing process because of unwashed when in initial use is easy to cause skin irritation, rubella or anaphylaxis, etc. when in direct contact with skin, the product is not sterilized, and when the wound is cared inadequately, the non-sterilized product directly contacts the wound to have infection risk. (2) The use is inconvenient, the product needs to be repeatedly cleaned after being stained with stains and blood stains after being worn, the use burden of a patient is increased, the existing product is mostly of fixed specifications, and the product cannot be individually adjusted according to the body type of the patient and the postoperative recovery stage. (3) The existing elastic body shaping clothes are not uniform in pressurization, the pressurization mode mainly depends on the elasticity of the fabric, accurate adjustment of local pressure is difficult to achieve, and tightening marks and wrinkles are easy to generate, so that uneven skin stress is caused. (4) The function is single, and the existing product lacks a detachable hard supporting structure and cannot meet different requirements of different recovery stages on the fixing strength and the shaping effect. Therefore, the prior art lacks a disposable sterile pressure dressing for operation which has good skin-friendly property, air permeability and hygroscopicity and can provide uniform and adjustable pressure Disclosure of Invention Aiming at the technical problems, the invention provides a disposable sterile elastic pressurizing dressing, which comprises the following technical scheme: The inner layer moisture absorption layer is made of skin-friendly breathable moisture absorption materials; the middle fixing layer is arranged on the outer side of the inner layer moisture absorption layer, and the edge of the inner layer moisture absorption layer is fixedly connected with the edge of the middle fixing layer in a sewing mode to form a double-layer composite structure; The middle supporting layer is arranged on the outer side of the middle fixing layer and comprises a plurality of strip-shaped cloth bags which are arranged in parallel and supporting pieces which are detachably accommodated in the strip-shaped cloth bags, the width of each strip-shaped cloth bag is matched with the width of each supporting piece, one end of each of the two ends of the strip-shaped cloth bag in the length direction is closed, the other end of each of the two ends of the strip-shaped cloth bag is provided with an opening, and the supporting pieces are inserted into or taken out from the opening; The outer layer pressurizing fixing band is arranged on the outer side of the middle supporting layer and comprises two trapezoid elastic clo
