Abstract

A kind of not health gauze of sticking wound surface, make through release treatment by common gauze, antitack agent in the treatment fluid is the amino modified siloxane emulsion of anionic or nonionic, and is added with a small amount of water absorbing agent, the anti-adhesive gauze of making after the dipping oven dry, nonirritant, good water absorption, the adhesion wound surface can alleviate sick and wounded's misery, there are materials significantly to reduce characteristics such as not flavescence, free from extraneous odour again, are convenient to promote.

Description

A kind of not health gauze manufacture method of sticking wound surface

The invention belongs to hygienic material.

Common health gauze is during as dressing wrapping wound surface, owing to absorb secretions such as pus and blood, is easy to and the wound surface adhesion, brings trouble in painful and the nursery work to the sick and wounded when changing dressings.Chinese patent application number is 871071444 prior art, hydroxy dimethyl silicone oil emulsion (abbreviation hydroxy silicone emulsion) is proposed as antitack agent, though the high polymer of itself has good physiology inertia, the not sticking effect of simple straight chain molecule is very low, thereby consumption is up to 5-20%.Organic silicone oil adopts different emulsifiers to make cationic, cloudy release, nonionic emulsion, cationic hydroxy silicone emulsion is done catalysis emulsifying with dodecyl dimethyl benzyl ammonium salt (being called for short 1227 quaternary ammonium salts), polymerization under strong basicity, can produce the activated side chain of micro tool, can produce slightly crosslinkedly during oven dry, sticking effect is more quite a lot of than anionic, and the commercially available prod mainly is cationic, still do not have nonionic, the not stick that above-mentioned by analysis prior art adopts is cationic hydroxyl breast.But its cationic emulsifier 1227 quaternary ammonium salts belong to toxicant.Japan's pick mouthful rich work " public hazards and poisonous substance danger " (an organic piece of writing) secretary is carried, with its LD50 value of frog test is 30mg/kg, when being the quite every kg body weight of feeding 30mg, having the half Rana nigromaculata to poison dies, and 1227 quaternary ammonium salts are generally about 1.2% at cation hydroxyl Ruzhong content, in 871071444 patents, when consumption is 10% concentration, 1227 content surpass 1000mg/kg on its anti-adhesive gauze, 1227 too high content have solidifying protein to hinder ill effects such as metabolism, and this is disadvantageous to the wound surface cambium.And 1227 too much quaternary ammonium salts, easily make the flavescence long afterwards of gauze day, and bad abnormal flavour is arranged.

Purpose of the present invention is to overcome the shortcoming of above-mentioned anti-adhesive gauze, and the low-temperature self-crosslinking type amino-modified silicone oil that adopts a new generation is as stick not, and be emulsified into anion or non-ionic emulsion, and add wetting agent as water absorbing agent, cannot not make stickingly effective, nonirritant, the anti-adhesive gauze of not yellowing.

Implementation method of the present invention is: common health gauze dipping is contained get product after handling the back drying in the treatment fluid of not stick and water absorbing agent.

The used not stick of the present invention is amino modified silicone emulsion, is called for short amino silicon breast, and its chemical structural formula is:

R1=OH or OR

The R2=aminoalkyl

Its structure itself has cross-linking agent and catalyst, thereby can be at low temperatures condensation cross-linking voluntarily, form the elasticity mocromembrane at fiber surface, change the helical arrangement of methyl on the linear siloxanes simultaneously, and the more neat outermost layer that is arranged in, this has further improved the water repellency of handling the back gauze again and has not glued effect:

Thereby with compare without crosslinked hydroxy silicon oil, consumption can descend significantly.Its emulsion can be anionic or nonionic, the amino silicon breast sodium alkyl benzene sulfonate emulsifying of anionic, and it is the effective ingredient of the detergent used always, is considered to nontoxic.Emulsion solid content 20%, be light grey translucent, placing 1 year can breakdown of emulsion layering working concentration in release treatment liquid be not 0.1～1.0%, the anhydrous sorbitol class emulsifying agent emulsifying of the amino silicon breast of nonionic, be white emulsion, also be about 0.1～1.0% when consumption is rolled over 20% solid content, the equal nonirritant of the emulsifying agent of selecting for use is so the anti-adhesive gauze of making is safe and non-stimulating property.

The water absorbing agent that the present invention is used, it can be the middle-and-high-ranking polyoxyethylenated alcohol of nonionic, trade name is a penetrating agent JFC, consumption in treatment fluid is 0.01～0.1%, it also can be the powder that draws back of anionic, consumption in treatment fluid is 0.02～0.2%, all belongs to the nonirritant surfactant, and can not produce the problem that the easy oxidation deterioration of oils and fats is closed in insatiable hunger in the sulfonated castor oil.

Embodiments of the invention are as follows:

In 80 liters of light waters, add amino silicon breast respectively according to following table is described, penetrating agent JFC or with the dissolved powder that draws back of a small amount of warm water, supplementing water to 100 liter stirs, and gauze is dried about 100 ℃ and is got product after insulation is padded.

Penetrating agent JFC (CC) 10 30 100

Draw back powder (gram) 10 80 200

Add water (liter) 100 100 100 100 100 100

The anti-adhesive gauze that utilizes the present invention to make, pure white softness, nonpoisonous and tasteless, the moistening water absorbing force is good, after surgical clinical is used, does not all have and the wound surface adhesion phenomenon, and the trouble of sick and wounded's misery with nursery work removed in nonirritant and untoward reaction.

The anti-adhesive gauze that the present invention makes is selected from the amino modified siloxanes of cross-linking type, and anti-adhesion effects is good, and compares with hydroxy silicone emulsion, and materials significantly reduce, and cost reduces, and not flavescence, free from extraneous odour are easy and simple to handle, are easy to promote.

Claims (3)

1, a kind of health gauze of not sticking wound surface is characterized in that being flooded through the treatment fluid that antitack agent and water absorbing agent are formed by common health gauze and makes after drying, and said antitack agent is: amino modified siloxanes, and its structural formula is as follows:

Its emulsion can be an anionic, also can be nonionic, its in treatment fluid when solid content is 20%, consumption is 0.1～1.0%.
