Abstract

The invention belongs to the technical field of operating instrument set materials, and concretely relates to a composite material for manufacturing elastic operating instrument sets, and a preparation method thereof. The composite material for manufacturing elastic operating instrument sets comprises an elastic layer, and a fireproof layer and a sterilizing layer which are respectively arranged on two sidewalls of the elastic layer, a waterproof layer is arranged on the other surface of the fireproof layer, and a water absorbing layer is arranged on the other surface of the sterilizing layer.The preparation method of the composite material for manufacturing elastic operating instrument sets concretely comprises the following steps: S1, uniformly coating the surface of a carrier with an elastic layer raw material; S2, laying the sterilizing layer on the formed elastic layer; S3, bonding the water absorbing layer to the sterilizing layer; S4, arranging the fireproof layer on the othersurface of the elastic layer; and S5, arranging the waterproof layer on the surface of the fireproof layer. The preparation process is simple, and the finished product has the characteristics of goodtoughness and softness.

Description

technical field [0001] The invention relates to the technical field of surgical pack materials, in particular to a composite material for manufacturing elastic surgical packs and a method thereof. Background technique [0002] With the continuous development of clinical medicine, biomedical elastomer materials have been more and more widely used. Surgical packs are usually composed of large cloth, surgical drapes and Meiya bags, and other surgical accessories are added according to surgical requirements. Surgical drapes are the core of the entire surgical package. The materials used for surgical drapes are composite materials; their main characteristics are good water resistance (water-blocking non-woven fabric), good water absorption (water-absorbent non-woven fabric), high hydrostatic pressure, and flexibility. Good strength, less lint, imported adhesive (non-allergic), antistatic, anti-alcohol, anti-plasma, anti-oil, etc.; but the existing surgical kits have the problems...
