Absorbent napkin

 

(57) Abstract:

Napkin comes to dressing devices based balagopalan materials for wound care and ensuring improvement of the efficiency of prevention of nosocomial infection. Absorbent towel is made manageradobe material containing cellulose, viscose fiber, modified carbon aluminum oxide with a specific surface area of 80 to 300 m2/g, volume of pores with a radius of 100 - 1000 0,008 - 0,250 cm3/g and with a radius of 1000 - 10000 0,005 - 0,100 cm3/g -11,5 - 23,0, crosslinked polyvinyl alcohol with a water absorption of 1500 - 2100% and fibrous sodium carboxymethyl cellulose with a degree of water retention 350 - 700%. The napkin may further have a locking element located on manageradobe material with the possibility of attaching the cloth to the skin. Proposed napkin has an improved operational properties by giving her a complex sorption properties, as well as selective sorption to pathogenic microflora without the use of antiseptics and drugs. 1 C.p. f-crystals, 1 table.

The invention relates to the production of means on the basis of balagopalan materials in frequent is opractice complications in the treatment of wounds of various etiologies through the use of a sterile dressing devices of the present level of quality.

Known absorbent cloth, made of fibrous material, consisting of a mixture of viscose (66 wt.%) and polyester (34 wt.%) fibers (Directory "for All clinic" N 1, "wound Care",, Heidenburg/Brenz, Germany, publ. August 1992, pages 8 - 9).

Such absorbent cloth with high enough, high absorbency characteristics, does not have a stimulating influence on wound healing.

The closest analogue of the present invention is an absorbent napkin made from manageradobe material containing cellulose, viscose fiber and polymer binder (SU 827670, CL/ A 61 L 15/20, 1981).

As the polymer binder numerophobia material contains waterproof synthetic resins or latexes, in particular melamine-formaldehyde resin or Acrylonitrile latex brand SKN-40-GP.

However, having antimicrobial activity due to the introduction of antiseptics and sufficient mechanical strength in the wet state, this cloth does not allow for using effective treatment and preventative care, because the use of the composition of medical tissues therapeutic drugs leads, on the one hand, the new technical result from the use of the present invention is to improve operational properties of absorbent wipes by giving her a complex sorption properties, as well as selective sorption to pathogenic microflora without the use of antiseptics and drugs.

This result is achieved by the fact that in the absorbent napkin made from manageradobe material containing cellulose, viscose fiber and polymer binder, numerophobia material further comprises a modified carbon aluminum oxide having a specific surface area of 80 to 300 m2/g, pore volume with a radius of 100 - 1000 0,008 - 0,250 cm3/g and with a radius of 1000 - 10000 0,005 - 0,100 cm3/g, and as the polymeric binder is a mixture of a modified epichlorohydrin fibrous sodium carboxymethyl cellulose with a degree of water retention 350 - 700% and crosslinked polyvinyl alcohol with a water absorption of 1500 - 2100% in the following ratio of these components (in wt.%):

Cellulose - 14,4 - 19,2

Viscose fibre - 46,0 - 56,0

Modificirvannie carbon-aluminium oxide - 11,5 - 23,0

Modified with epichlorohydrin fibrous sodium carboxymethyl cellulose was 8.8 to 14.1

Crosslinked polyvinyl alcohol - 3,0 - 4,0

The napkin may further have a locking element located on manageradobe material with fastening her (salve which is about the same size as the size manageradobe material, intended for applying to the wound and exposed peripheries covered with an adhesive for attaching the dressing tool to the skin.

Regional areas may extend beyond the Central portion of the locking element or from two opposite sides, or around its perimeter.

While the Central part for convenience in manufacture can be with boundary areas completely covered by adhesive or partially covered them. Covering the Central part of the adhesive can be carried out in the region adjacent to the protruding edge sections of the locking element or discretely over the entire surface of the Central part of the element.

The locking element is made mainly of manufactured chemical fiber paper, on the surface of which is marked sticky adhesive, such as acrylic.

The adhesive is protected with a release layer is removed during use. The latter is made from siliconized paper or polyethylene terephthalate film.

Numerophobia material is made "wet" method of the paper machine from the composition of the above composition.

Sheet material McCoy 200 - 250 g/m2make cf> The cloth may be subjected to steam sterilization, and radiation method.

We offer absorbent napkin has a new complex sorption properties.

This is due to the use of manageradobe material, in which is found a new combination of a polymeric binder (a mixture of fibrous sodium carboxymethyl cellulose (Na) and partially crosslinked polyvinyl alcohol (PVA) with defined experimentally established optimum characteristics: the degree of water retention of the fibrous Na - 350-700%, water absorption crosslinked PVA - 1500-2100% and modified carbon aluminum oxide (carbonaceous mineral sorbent having a specific surface area of 80-300 m2/g, pore volume with a radius of 100-1000 0,008-0.25 cm3/g and with a radius of 1000 - 10000 0,005-0,100 cm3/g).

Fibrous Na produced according to TU 6-05-5146-86 or THE 6-55-221-1010-89, creates a structure of a material in conjunction with pulp and viscose fiber, providing a high sorption properties of the material.

Crosslinked PVA produced according to TU 6-05-05-277, contributing to a sharp decline in the reverse phenomenon of sorption. This specific selective sorption material in relation to pathogenic mardom of aluminum oxide with certain characteristics of porosity and specific surface area (product SUMS-1. produced by FS N 42-3283).

The table presents the indicators absorbent wipes, made of manageradobe material, at various ratios of its components, as well as certain characteristics of their physical properties.

The table shows that the proposed single-layer tissue through the use of specific manageradobe material has high absorbency and microbial sorption, which will allow to apply it successfully for wound closure with the initial microbial colonization of 104-105microbial cells/cm2.

We offer absorbent cloth provides third - fifth day of the treatment process reduced the number of microbial bodies on 1 cm2to (4 - 8,6)103while widely used at present, medical wipes, medical gauze, soaked in hypertonic solution (0.9% NaCl), provide for the treatment of wounds of the value of the same indicator, comprising not less than 1,3104.

In addition, if the proposed napkin locking element it provides ease of operation without the use of special fixtures.
