Problems solved by technology

[0002] At present, in clinical practice, the main method of cleaning the wound during the operation is to use ordinary degreasing gauze and the method of cannula irrigation. This method uses too much gauze, and the speed of absorbing exudate is also slow, and the labor intensity is high. , the water quality requirements for casing flushing are very high, and the water also needs to solve the process problem of moisture absorption

Embodiment Construction

[0007] Cut the 2.5-3.0 denier fibers of the spun multi-component copolymerized acrylic acid into 38-65mm long short fibers, and needle them into 120-150g non-woven fabrics under the condition of ambient humidity of 10-15%. Cloth, cut into 10cm×10cm squares, and then use ultrasonic to punch the PE film to form an impermeable membrane, and seal the four sides of the cut into 10cm×10cm squares. Then the hollow acetate fiber non-woven fabric that has been impregnated with soluble chitosan and then dried is punched with ultrasonic waves to form an impermeable membrane, which has been wrapped into a 10cm×10cm square and sealed again on all four sides. Finally, it is sealed and packed in a polyester bag to leave the factory. The above production conditions must be completed in a dry environment with an air humidity of 10-15%.

[0008] PE perforated anti-seepage membrane is 15 grams per square meter. It adopts funnel-shaped hexagonal or plum blossom, five-sided and other shapes. The ...

Abstract

The invention relates to a method for preparing a medical dressing of adsorbing liquid and hemostatic, comprising: cutting the fiber of 2.5-3.0 denier of the woven polyatomic acid acrylic copolymer to short fiber of 36-65mm, punching to non-woven fabrics, cutting into diamonds, then perforating the PE membrane into impermeable membrane with supersonic wave, enclosing the four edges of the cut diamond; perforating the PE membrane into impermeable membrane with supersonic wave using the dried hollow acetate fibre non-woven fabrics immersed with soluble chitose, enclosing the four edges of the cut diamond, packing with polyester packing bag. The whole preparing process is carried out under dry condition with the relative humidity between 10% to 15%. The product is mainly used to remove the large quantity of wound effusion and make the effusion be adsorbed quickly, and realize purpose of hemostatic, antibiotic, cleaning operation wound, no pollution by foreign liquid and exudasion, which guarantee the operation carried out successfully.

Description

Technical field: [0001] The invention relates to a preparation method of a liquid-absorbing hemostatic medical dressing. Background technique: [0002] At present, in clinical practice, the main method of cleaning the wound during the operation is to use ordinary degreasing gauze and the method of cannula irrigation. This method uses too much gauze, and the speed of absorbing exudate is also slow, and the labor intensity is high. , The water quality requirements for casing flushing are very high, and the water also needs to solve the process problem of moisture absorption. Invention content: [0003] In order to solve the above problems, the present invention provides a method for preparing a super-absorbent hemostatic dressing for surgery using super-absorbent and blood-absorbing fibers of multi-component copolymerized acrylic acid as the main material. [0004] The invention discloses a preparation method of a medical liquid-absorbing hemostatic dressing, which is made ...
