Problems solved by technology

The existing technical solutions for "wound dressings" have their own advantages, but according to the "gold standard" of chronic wound treatment, that is, the theory of "healing in a moist environment for wounds", using the characteristics of strong water absorption of nano-polysaccharide materials, the development "Wound dressings" that allow medical wound dressings to have a moist wound environment are rare

Embodiment example 1

[0019] Example 1 - Hydrocolloid Dressing Containing Nanocellulose

[0020] In order to prove the effect of nanocellulose on the water absorption of hydrocolloid dressings, the composition of the wet dressings is the same, the number of antioxidants added is the same, only the polysaccharide compounds or derivatives added are changed according to the number of parts by mass. The following three components:

[0021] Component one: the wet dressing is a hydrocolloid dressing, and the hydrocolloid dressing includes 18 parts of linear SIS (styrene-isoprene) block copolymer, 13 parts of olefin copolymer, 22 parts by mass Parts of C5 petroleum resin, 10 parts of naphthenic oil 4010, 28.2 parts of hydrophilic material sodium carboxymethyl cellulose, 6.6 parts of pectin, and 2 parts of antioxidant 1010; The number of parts is 0.4 parts of nanocellulose, and the average particle diameter of nanocellulose is 200 nm. Its water absorption see figure 1 .

[0022] Component 2: the wet dr...

[0024] Implementation Case 2—Silicone Gel Dressing Containing Nano-Amylose

[0025] The wet dressing is a silicone gel dressing, and the silicone gel dressing includes 60 parts of polydimethylsiloxane, 18 parts of multi-carbon alkyl polysiloxane, 20 parts of polydimethylsiloxane in parts by mass. Siloxane cross-linked polymer; the nano-polysaccharide compound or derivative added is 2 parts by mass of nano-amylose, and the average particle size of nano-amylose is 300nm.

Embodiment example 3

[0026] Implementation Case 3 — Alginate Dressing Containing Nano-Carboxymethyl Cellulose Sodium

[0027]The wet dressing is an alginate dressing, and the alginate dressing comprises 85 parts by mass of water, 6 parts of sodium alginate, 3 parts of calcium chloride; also added nanopolysaccharide compounds or derivatives. It is 2 parts by mass of nanometer sodium carboxymethylcellulose, and the average particle size of nanometer sodium carboxymethylcellulose is 350 nm.

Abstract

The invention provides medical wound dressing containing nano polysaccharides, and belongs to the technical field of medical wound dressing. The medical wound dressing comprises wet dressing, and thewet dressing is hydrocolloid dressing or hydrogel dressing or silicon gel dressing or alginate dressing. The medical wound dressing is characterized in that nano polysaccharide compounds or derivatives are also added to the wet dressing, and the added nano polysaccharide compounds or derivatives are one or more of cellulose, starch, chitin, chitosan or derivatives; the particle size of the polysaccharide compounds or derivatives is 200nm-1000nm; and the parts by mass of the polysaccharide compounds or derivatives and the wet dressing are respectively 0.1-20 parts and 70-115 parts. The medicalwound dressing provided by the invention has the advantages that the nano polysaccharides and the wet dressing are mixed, so that the wound dressing can quickly absorb wound exudate and has good moisture keeping performance; and furthermore, the mechanical performance of the dressing can be enhanced in an auxiliary mode.

Description

technical field [0001] The invention belongs to the technical field of medical wound dressings, in particular to a medical wound dressing containing nano polysaccharides. Background technique [0002] Medical wound dressings are widely used in healing people's wounds, so people have proposed many "wound dressings" technical solutions, such as the announcement number: CN 102088937 A "wound dressing", announcement number: CN102784411A "wound dressing", announcement number: CN 103861144A "medical dressing and its preparation method", announcement number: CN 102625686B "antimicrobial medical dressing and protection of wound and catheter site", etc. The existing technical solutions for "wound dressings" have their own advantages, but according to the "gold standard" of chronic wound treatment, that is, the theory of "healing in a moist environment for wounds", using the characteristics of strong water absorption of nano-polysaccharide materials, the development "Wound dressings"...
