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:
The present invention relates to a kind of manufacture method of liquid-absorbent hemostatic medical dressing.
Background technology:
At present clinically, the method of main cleaning wound surface in the process that operation is carried out, be to adopt common absorbent carbasus and sleeve pipe process of washing, the use gauze amount of this method is too big, and the speed that absorbs sepage is also slow, labor intensity is big, and the water quality requirement of sleeve pipe flushing is very high, and water will solve the working-procedure problem of moisture absorption equally in addition.
Summary of the invention:
For addressing the above problem, the invention provides a kind of super-strong moisture absorbing of multi-component copolymer acrylic acid class, fiber of sucking blood of adopting is the preparation method of the operation of material of main part technology with superpower liquid-absorbent hemostatic dressing.
The preparation method of a kind of liquid-absorbent hemostatic dressing for medical use of the present invention, it is to be the method for material of main part employing acupuncture by the super-strong moisture absorbing of multi-component copolymer acrylic acid class, the fiber of sucking blood, make non-woven fabrics, around the skin of non-woven fabrics, wrap the anti-reverse osmosis layer of one deck, around this, wrap hollow acetate fiber non-woven fabrics again by soluble chitosan dipping after drying.
The fiber at the 2.5-3.0 dawn of the multi-component copolymer acrylic acid class that it will spin is cut into the long short fiber of 38-65mm, acupuncture becomes non-woven fabrics, cut into square, it is good square four bandings of cutting with ultrasound wave the PE film to be punched into antiseepage film then, again will be with the hollow acetate fiber non-woven fabrics of soluble chitosan dipping after drying, adopt ultrasound wave that the PE film is punched into square four limits that antiseepage film has been bundled into and seal once more; Adopt the polyester packages bag hermetic package to dispatch from the factory at last.Preparation process should be in the dry environment of 10-15% in air humidity.
Super-strong moisture absorbing, the fiber of sucking blood of multi-component copolymer acrylic acid class should be dry shape, and the multiplying power that absorbs water, sucks blood is 60-150 a times of own wt, could keep the dry and comfortable of wound, wound surface during use.The hollow acetate fiber non-woven fabrics of soluble chitosan dipping after drying is mainly used in suction, sucks blood and antibiotic, while hemostatic effect again, the flexibility of hollow acetate fiber non-woven fabrics in addition, compliance and do not damage wound surface.The operation that the present invention relates to is with the preparation method of superpower liquid-absorbent hemostatic dressing, be to solve the medical worker, when surgical patient undergos surgery, the liquid-absorbent hemostatic material of a kind of simple and fast of being taked, medical personnel's the labor intensity of wiping bloodstain again and again with gauze has been saved in use of the present invention, and because the existence of soluble chitosan, hemorrhage to wound after surgery, played the hemostatic effect, because of the operation that the present invention relates to especially big with the liquid absorption of superpower liquid-absorbent hemostatic dressing.Therefore significantly reduce access times, saved cost, reduced patient's burden.
The specific embodiment:
The fiber at 2.5-3.0 dawn of the multi-component copolymer acrylic acid class that spinned is cut into the long short fiber of 38-65mm, under the situation of ambient humidity 10-15%, acupuncture becomes the non-woven fabrics of 120-150 gram, cut into the square of 10cm * 10cm, with ultrasound wave the PE film being punched into antiseepage film then, will to cut into square four bandings of 10cm * 10cm good.Again will be with the hollow acetate fiber non-woven fabrics of soluble chitosan dipping after drying, adopt ultrasound wave that the PE film is punched into square four limits that antiseepage film has been bundled into 10cm * 10cm and seal once more.Adopt the polyester packages bag hermetic package to dispatch from the factory at last, above working condition all must be finished in air humidity is the dry environment of 10-15%.
PE punching antiseepage film is every square metre 15 gram.Adopt funnel type hexagonal or type shapes such as Flos Mume, five limits, after funnel-form outwards its objective is that a large amount of transudates with wound, wound surface are drawn onto in the multi-component copolymer acrylic fiber, just reverse osmosis comes out and contaminated wound once more, makes wound, the wound surface dry and comfortable state that keeps clean forever.
Claims (3)
1, a kind of preparation method of liquid-absorbent hemostatic dressing for medical use, it is to be the method for material of main part employing acupuncture by the super-strong moisture absorbing of multi-component copolymer acrylic acid class, the fiber of sucking blood, make non-woven fabrics, around the skin of non-woven fabrics, wrap the anti-reverse osmosis layer of one deck, around this, wrap hollow acetate fiber non-woven fabrics again by soluble chitosan dipping after drying.
2, method according to claim 1, the fiber that it is characterized in that the 2.5-3.0 dawn of the multi-component copolymer acrylic acid class that will spin is cut into the long short fiber of 38-65mm, acupuncture becomes non-woven fabrics, cuts into square, and it is good with square four bandings of cutting with ultrasound wave the PE film to be punched into antiseepage film then; Again will be with the hollow acetate fiber non-woven fabrics of soluble chitosan dipping after drying, adopt ultrasound wave that the PE film is punched into square four limits that antiseepage film has been bundled into and seal once more; Adopt the polyester packages bag hermetic package to dispatch from the factory at last.
3, method according to claim 2 is characterized in that preparation process is in the dry environment of 10-15% in air humidity.
