Description

The medical pad of nanometer silver antimicrobial

Technical field

The design relates to the disposable sanitary liquid absorbing pad, especially is applicable to the pad of patient, people with disability, old man and infant nursing, belongs to the nursing materials field.

Background technology

1, new visible through looking into of existing medical pad Patent data; The characteristic range and the developing state of many medical pad patent application cases are: hierarchy, can absorb water or high suction, contain medicine maybe can change abnormal smells from the patient, cost lower, make things convenient for post processing or can high-fallly separate etc.The medical pad of existing market roughly can be classified as follows: 1) only possess simple absorbent function; 2) Chinese herbal medicine (granule) is as anti-biotic material and the common complex functionality layer of absorbent material; 3) the nanometer silvering solution is soaked into the common complex functionality layer in back etc. as anti-biotic material by non-woven fabrics etc.

Corresponding to must possessing of antibiotic and sterilizing function; The material of the existing medical pad of existing market uses and technological design does not reach comprehensive optimization as yet; Problem mainly is present in the additional link of functional material; As the imbibition poor effect that absorbs water, or antibacterial effect a little less than, or the loaded down with trivial details cost of manufacturing procedure high (soak like medicinal liquid then will dry oven dry etc.) or the like.

2, the Chinese invention patent " nanometer silver-super absorbent resin composite and radiation method production technology thereof " of Anhui China brilliant new material company limited application discloses a kind of nanometer silver-super absorbent resin composite that adopts the radiation chemistry prepared; Material powder particle diameter≤100 orders; Its resin is the cross-linking type hydrophilic polymer; The three-dimensional network length of side≤100nm that resin is inner, the Ag simple substance of particle diameter≤100nm evenly is compounded in the resin three-dimensional network; Content of nanometer silver>=50ppm in the composite, the content of nanometer silver>=170ppm of outstanding antibiotic and sterilizing effect.

Nanometer silver-super absorbent resin product key property is following:

Water content＜7% is inhaled distilled water multiple >=430

Inhale saline multiple >=50 and protect saline multiple >=38

Pressurization is inhaled saline multiple>=28 and is inhaled salt water speed≤32s

With " disposable use hygienic article sanitary standard " serves as to detect foundation (GB15979-2002); Nanometer silver-High hydrophilous resin composite products is confirmed through anti-biotic material inspection center of Physical Chemistry Technology Inst., Chinese Academy of Sciences: to the escherichia coli bacteriostasis rate greater than 99%; To the staphylococcus aureus bacteriostasis rate greater than 99% (examining report numbering: LHKJ-0906-02-1/1, LHKJ-0906-03-1/1), so above-mentioned nanometer silver-super absorbent resin product is that the good health of a kind of fungistatic effect is with functional type macromolecule water uptake new material.

Summary of the invention

Anti-cross infection demand to infectious disease patient, highly pathogenic pathogenic bacteria virus carrier; To people with disability, old man and the infant nursing demand of critically ill patient, long-term bed, the task of this utility model is: a kind of new medical pad that high power water-absorbing has outstanding antibacterial functions concurrently that possesses is provided.

This utility model design is: a kind of medical pad passes through liquid zone, antibiotic high suction zones and bottom surface antiseepage district for end face from top to bottom, more than the mutual associated methods class of three being integrally formed of functional areas like existing medical pad.The end face of the medical pad of this utility model passes through the liquid zone and can be made up of monolayer or non-monolayer material; Should be beneficial to the rapid permeability of body fluid (urine, the corrupt liquid of people's body surface, blood etc.); And not intussusception body fluid or absorb body fluids not basically itself; And take into account the comfort that human body skin touches subsides, material can be non-woven fabrics, dust-free paper, common absorbent paper etc.; The antiseepage district, bottom surface of the medical pad of this utility model also can be made up of monolayer or non-monolayer material, and the monolayer of this moment should guarantee under opposite extreme situations, not take place the generation of body fluid infiltration incident; The enhancement Layer that a breakage-proof can also be arranged under the monolayer, material can be non-woven fabrics etc.; What in antibiotic high suction zones, realize antibiotic and high absorbent function simultaneously is to be powdered nanometer silver-super absorbent resin composite; The particle diameter of material powder≤100 orders; Its resin is the cross-linking type hydrophilic polymer, the good invariably abnormal smells from the patient of nanometer silver-super absorbent resin composite.

Nanometer silver-super absorbent resin composite powder both can directly be laid between the 1st, 3 districts, also can be encapsulated by liquid permeability ability good suction paper bag or non-woven bag, and the bigger pouch of area can also be separated into the less piece of area by the sewing route.

The good effect of this utility model product design is: high-strength broad-spectrum antimicrobial effect and outstanding high-hydroscopicity can be realized by a kind of composite simultaneously, are particularly conducive to self-cleaning the keeping a public place clean of antibiotic and sterilizing under abominable wound, skin infection, the urinary incontinence situation; Exsiccant composite powder is beneficial to the quick production in enormous quantities of absorbent paper product; The degradable of composite is beneficial to the environmental protection post processing.

Continue explanation this utility model below.

1, visible through above routine 1-7, the progressive essence of this utility model product is: the main material of changing existing product with the functional material of present the best has been realized the technology upgrading of Medical napkin flake products.The many concrete difference structures of existing products in markets do not hinder the expression and the protection of this utility model intention.

2, under field conditions (factors); Nanometer silver-super absorbent resin composite as this utility model function of tonic chord material; The degradable in a short time or microbial degradation of macromolecule resin wherein, and the silver-colored simple substance of nontoxic script Nano grade has further polymeric tendency.

3, the super absorbent resin in the design's composite (Super Absorbent Resin is called for short SAR) has a lot of excellent specific properties: but high water absorbent rate-absorptance is from tens times of heavy sensation of the body even thousands of times deionized water or tens times 0.9% normal saline; Even water holding capacity is strong-and SAR sucks under the pressurized condition water also is difficult for being extruded; Have the advantage of macromolecular material-be easy to processing, easy to use etc.

4, the nanometer silver in the design's composite is the argent simple substance of particle diameter≤100nm, has following characteristics as the latest generation natural antibacterial agent:

Broad-spectrum antiseptic.Nano-Ag particles directly gets into thalline and oxygen metabolism enzyme, and (SH) combine, the unique effect mechanism that thalline is choked to death can be killed microorganisms such as most of antibacterials of being in contact with it, fungus, mycete, spore, can kill equally the antibiotics fastbacteria.

The property killed is strong.Nanometer silver can kill 650 various bacteria in several minutes.Nano-Ag particles is at low concentration kill pathogenic organisms rapidly just, and bactericidal activity is stronger when meeting water.

Safety non-toxic.The Compendium of Material Medica record: give birth to silver, nontoxic.Explanation in U.S. public health bureau nineteen ninety " about the toxic investigation report of silver ": silver does not have obvious toxic-side effects to human body; Poor nanometer silver local application is safest application method.Through test, mice is at oral maximum tolerated dose 925mg/kg, do not have any toxic reaction when promptly being equivalent to 4625 times of clinical using dosage.
