Abstract
The invention relates to an internal absorbable hemostasis tablet, which structurally comprises a protecting layer, an alginate fiber layer, a biodegradable hemostasis material layer, a biodegradable adhesion-proof material layer and a bottom membrane layer with air vents from top to bottom. The hemostasis material layer is jointed with the adhesion-proof material layer via an anode and cathode ionic bond effect, and finally the hemostasis material layer, the adhesion-proof material layer and the alginate fiber layer are poured together. The hemostasis tablet is simple in structure and rapid in hemostasis, and is safe and reliable.
Description
Technical field
The present invention relates to a kind of hemostasis sheet, absorbable hemostatic sheet in specifically a kind of body.
Background technology
Operating room hemostasis method commonly used has: clamp, hemostasis by ligation, electricity coagulates, ultrasonic hemostasis, hemostasis by compression and drug hemostasis.Present absorbable hemostatic material on the market has: absorbable fibre albumin glue, oxidized cellulose and oxidized regenerated cellulose, chitosan class hemostatic material, absorbability gelfoam and gelatin fiber net, microfibre collagen and collagen fiber net, calcium alginate fibre etc.Bibliographical information products such as independent Antiadhesive film, sthptic sponge, hemostatic gauze are arranged, perhaps be known as the material that anti and hemostasis dual-use function are arranged.Also do not have and can multiple materials with function be cast in hemostasis articles for use together.
Summary of the invention
The technical problem that the present invention will solve provides absorbable hemostatic sheet in a kind of body, and is simple in structure, hemostasis is rapid, safe and reliable.
In order to overcome the defective that exists in the background technology; The technical solution adopted for the present invention to solve the technical problems is: absorbable hemostatic sheet in a kind of body; Its structure comprises overcoat, alginate fibre layer, biodegradable hemostatic material layer, biodegradable adherence preventing material layer from top to bottom, and the basal membrane layer of air-vent is arranged.Between hemostatic material layer and the adherence preventing material layer is to engage through the effect of zwitterion key, is cast in the alginic acid fibre layer at last.
Described hemostatic material layer is for covering and be bonded in the hemostasis sheet above the adherence preventing material layer.
Described hemostatic material layer utilizes the crosslinked action of zwitterion, and the hyaluronic acid of band anion and the chitosan of band cation are passed through ionomer, is cast in alginic acid fibre.
Advantage of the present invention is:
1, this hemostasis sheet has improved hemostatic intensity.
2, the effect that suppresses various bacteria and conk is arranged; Reduced the inconvenience of medical personnel's operating process.
Description of drawings:
Fig. 1 is the longitdinal cross-section diagram of absorbable hemostatic sheet in a kind of body.
Labelling in the accompanying drawing is represented respectively:
1, overcoat, 2, the alginic acid fibre layer, 3, the hemostatic material layer, 4, the adherence preventing material layer, 5, the basal membrane layer of air-vent arranged.
The specific embodiment:
Referring to accompanying drawing 1, absorbable hemostatic sheet in a kind of body of patent of the present invention is further described.
Absorbable hemostatic sheet in a kind of body, its structure comprises overcoat 1, alginic acid fibre layer 2, hemostatic material layer 3, adherence preventing material layer 4 from top to bottom, and the basal membrane layer 5 of air-vent is arranged.
Between described hemostatic material layer 3 and the adherence preventing material layer 4 is to engage through the effect of zwitterion key.
Described hemostatic material layer 3 is for covering and be bonded in adherence preventing material layer 4 upper strata.
Described hemostatic material layer 3 utilizes the crosslinked action of zwitterion, with alginic acid fibre layer 2, adherence preventing material layer 4, has the basal membrane layer 5 of air-vent to be cast in together.
Tear overcoat 1 during use, can stop blooding wound.Alginic acid fibre layer 2 direct wound contacting are oozed out the position of body fluid; Hemostatic material layer 3 can dissolve naturally; Form on thin film covering and the wound; And can not produce adhesion with wound, simultaneously hemostatic material layer 3 also contains the medicine of antibiotic, antiinflammatory, anastalsis, thereby reaches rapid, the safe and reliable good result of hemostasis.
The present invention is the known technology of those skilled in the art except that the described technical characterictic of description, can process shown in the accompanying drawing to specifications.
Claims (3)
1. the interior absorbable hemostatic sheet of body is characterized in that structure comprises overcoat (1), alginic acid fibre layer (2), hemostatic material layer (3), adherence preventing material layer (4), and the basal membrane layer (5) of air-vent is arranged.
2. absorbable hemostatic sheet in a kind of body according to claim 1 is characterized in that, is to engage through the effect of zwitterion key between hemostatic material layer (3) and the adherence preventing material layer (4).
3. absorbable hemostatic sheet in a kind of body according to claim 1 is characterized in that, hemostatic material layer (3) is for covering and being bonded on the adherence preventing material layer (4).
