Problems solved by technology

In order to improve the therapeutic effect of using hypertonic solution soaked gauze wet compress method to treat human skin and tissue edema caused by exudate or trauma in infusion in clinical work, and overcome some shortcomings of soaked gauze wet compress method at the same time, the present invention adopts The method of adding a water-soluble polymer to the hypertonic solution converts the hypertonic solution into a colloidal form to prepare a colloidal dressing. The hypertonic colloidal dressing can improve the therapeutic effect and overcome some shortcomings of wet compresses, such as: The solution needs to be temporarily prepared before use, the gauze needs to be replaced frequently during use, and the solution is easy to leave stains after the clothes are dried.

Abstract

The invention belongs to the field of medical technologies and relates to a medical colloid dressing for preventing and treating human skin or tissue edema and pain and a preparation method thereof. In clinic treatment, the medical staff often adopts the method that gauze is soaked in a hypertonic solution and hydropathic compress is carried out to treat human skin or subcutaneous tissue edema caused by seepage or trauma during transfusion, the method is to be promoted in the therapeutic effect and is defective. According to the invention, the method that a water-soluble polymer is added is adopted, the hypertonic solution is converted into a colloid state, and the colloid dressing in the hypertonic state can promote the therapeutic effect better and overcomes the defects of hydropathic compress. When in use, the colloid dressing is tightly adhered to the skin or tissue of a swollen part, and an osmotic pressure difference is formed between the dressing and interstitial fluid in skin tissues, so that a part of water in the tissues of the swollen part is extracted in short time, damage to local tissue caused by edema is reduced, and the effects of local prevention and treatment are realized.

Description

technical field [0001] The invention belongs to the field of medical technology, and relates to a medical colloid dressing containing metal ions and water-soluble polymers capable of absorbing part of the water in local skin or tissues, specifically a hyperosmotic dressing capable of reducing swelling and relieving pain. Effective medical colloid dressing and preparation method thereof. Background technique [0002] Local skin and subcutaneous tissue edema is more common clinically, and the main causes of local skin and subcutaneous tissue edema are: (a) Extravasation of the drug solution during intravenous infusion or superficial phlebitis. Swelling and pain in the local skin and subcutaneous tissue due to phlebitis or the infusion of the drug solution into the surrounding tissue during intravenous infusion is relatively common clinically, especially in patients with malignant tumors and neurology patients who use chemotherapy drugs and macromolecular diuretics, often Caus...
