Problems solved by technology

When the skin is injured, choose a suitable wound dressing to cover the wound, which can help control bleeding, prevent infection and absorb secretions, thereby promoting rapid wound healing. The current medical wound dressing is generally made of gauze or non-woven fabric and cotton with drugs. It can protect the wound from mechanical damage and prevent wound infection, but its antibacterial, liquid absorption, anti-inflammatory and other properties are not satisfactory

Embodiment 1

[0026] Weigh 10g of sodium alginate, 5g of glycerin, add 100mL of deionized water, stir to obtain a uniform viscous liquid, then squeeze and filter through a 100-mesh nylon mesh to obtain glue A; take another 3g of hydroxyethyl chitosan, add Mix 100 mL of water, 2 g of lactic acid and stir to dissolve, add 0.2 of Aina sesame oil and stir, squeeze and filter through a 100-mesh nylon mesh to obtain glue B. Stir and mix the glue A and glue B evenly, vacuumize and defoam, then extrude with an extruder, coat on a stainless steel belt or on the surface of a fabric, dry with hot air at 60°C to obtain an antibacterial and healing-promoting gel film, or It is coated on the surface of the non-woven fabric first and then dried with hot air at 60°C to obtain a dressing film with better strength.

Embodiment 2

[0028] Weigh 10 g of gelatin, 6 g of glycerin, add 100 mL of deionized water, stir to obtain a uniform viscous liquid; squeeze and filter through a 100-mesh nylon mesh to obtain glue A. Take another 3g of chitosan, add 50 mL of water, 1g of lactic acid and stir to dissolve, add 0.5g of Aina sesame oil and stir, then filter as above to obtain glue B. Mix glue A and glue B evenly, adjust the pH value to 5-7 with triethanolamine, vacuumize and defoam, then extrude with an extruder, coat on a stainless steel belt or attach to the fabric surface, and dry with hot air at 60°C An antibacterial gel film for promoting healing can be obtained, or a dressing film can be obtained by first attaching it to a non-woven fabric surface and then drying it with hot air at 60°C.

[0029] The film obtained by the above method is sliced, and then laminated with a film backing with certain moisture permeability, air permeability and adhesive force to form a dressing for nursing and treatment of open...

Embodiment 3

[0031] Weigh 8 g of gelatin and 6 g of glycerin, add 100 mL of deionized water, stir to obtain a uniform viscous liquid; extrude and filter through a 100-mesh nylon mesh to obtain glue A. Take another 3 g of chitosan, add 50 mL of water, 1 g of lactic acid and stir to dissolve, add 0.7 g of Aina sesame oil and stir, then filter as above to obtain glue B; mix glue A and glue B evenly, and use triethanolamine Adjust the pH value to 5-7, vacuumize and defoam, fill it in an aluminum-plastic tube for later use, squeeze it out and apply it to the wound surface when in use.

Abstract

The invention relates to the field of medical materials and a method for preparing functional dressing products. Made of cationic high molecular polymer and anionic high molecular polymer and auxiliary materials, the cationic high molecular polymer accounts for 2% to 6% by weight percentage; the anionic high molecular polymer High molecular polymer, accounting for 2% to 6%; the excipients are made of polyols, bioactive substances, organic acids and water, of which polyols account for 2.8% to 10%, and bioactive substances account for 0.2% to 2%, organic acid 0.5%~3% and water 4%~92%. The present invention not only satisfies the multiple physical performance requirements of the wound dressing, but also has antibacterial, anti-inflammatory and healing-promoting effects. It can be used for surgical wounds, ulcer healing, sinus wound perfusion, burn and scald wound care, etc.

Description

technical field [0001] The invention relates to the field of medical materials and a method for preparing functional dressing products. Background technique [0002] In medicine, medical wound dressing generally refers to a protective covering that temporarily covers the wound. When the skin is injured, choose a suitable wound dressing to cover the wound, which can help control bleeding, prevent infection and absorb secretions, thereby promoting rapid wound healing. The current medical wound dressing is generally made of gauze or non-woven fabric and cotton with drugs. It can protect wounds from mechanical damage and prevent wounds from being infected, but its antibacterial, liquid absorption, and anti-inflammatory properties are not satisfactory. Contents of the invention [0003] The technical problem to be solved by the present invention is to add a kind of plant named Ainaxiang which grows in Yunnan, Guizhou, Hainan Island and other places to the film-making or wound ...
