Embodiment Construction

[0014] The specific embodiment of the medical dressing of the present invention will be described in detail below with reference to the accompanying drawings.

[0015] figure 1 It is a structural schematic diagram of the medical dressing of the present invention. The medical dressing of the present invention at least includes two layers of an outer layer 1 and an inner layer 2, and the outer layer 1 and the inner layer 2 are pasted together, wherein the inner layer 2 is made of a textile material containing natural marine polymer chitosan fibers (hereinafter referred to as marine biological fiber material); the outer layer 1 is made of microporous polytetrafluoroethylene membrane material (hereinafter referred to as ePTFE membrane material). 3 is a surface layer, which can be cotton, or a textile material containing natural marine high polymer chitosan fibers. The thickness of the ePTFE membrane material is 20-70 μm. The textile material containing natural marine high polym...

Abstract

A medical dressing is composed of an internal layer made of chitosan fiber fabric and an external layer made of millipore teflon film. Its advantages are water-proof, strong moisture and air permeability, and multiple functions of killing and suppressing bacteria, relieving inflammation, stypticity, acesodyne, etc.

Description

technical field [0001] The invention relates to a medical dressing, in particular to a dressing used for bandaging a wound, a medical bed sheet and the like. Background technique [0002] At present, most of the medical dressings or medical sheets commonly used in the medical field are plant fiber cloth (such as cotton cloth or cotton gauze). Come to treat or disinfect, and these dressings can not be waterproof, when running into the people in the field to be wounded and need bandaging and processing, because weather (for example rainy day) or environmental factor make wound meet water infection. In addition, for some long-term bedridden patients, problems such as decubitus often occur, especially for those patients with incontinence, in order to avoid changing the entire bed when incontinence occurs, waterproof materials are often laid on the bed. Ordinary waterproof materials have no air permeability. Not only will it make the patient feel uncomfortable, but it will furth...
