Abstract

The utility model belonging to a medical antibiosis silvered polypropylene piece of webbing is characterized in that: out surface of the polypropylene piece of webbing (1) is covered by a silvered film (2), which is also in a webbing shape. The utility model uses silver particles as antimicrobial agents, via the chemical silvering technology using tartrate as reducer, produces the medical antibiosis silvered polypropylene piece of webbing to prevent the labor vamp from infecting. It the advantages of well micro-organism resistance, without drug tolerance, strong heat resistance.

Description

The silver-plated polypropylene mesh of medical antibacterial

One, technical field:

This utility model relates to a kind of medical supplies, particularly treats the silver-plated polypropylene mesh of medical antibacterial of abdominal external hernia clinically.

Two, background technology:

Abdominal external hernia is commonly encountered diseases and frequently-occurring disease clinically, and in recent years, doctor's using artificial sticking patch no tension force of carrying out hernia is repaired more and more generally both at home and abroad, and is subjected to people's attention day by day by the problem that sticking patch brought.The infection of hernia sticking patch is exactly to make the clinician feel one of most thorny issue at present.

The most widely used artificial sticking patch of tension-free hernioplasty is medical polypropylene mesh (polypropylene mesh clinically at present, PP), become the sticking patch network structure by the monofilament polypropylene woven, be processed into the smooth shape of typing, have very strong tension stress intensity, the very little foreign body reaction and the favorable tissue compatibility, can be soaked into by fibrous tissue rapidly after planting people's human body.And its chemical property quite stable has very strong acid-fast alkali-proof, and hygroscopicity is almost nil.Because polypropylene mesh does not have antibiotic function, and is improper as surgical procedure, wound infection may occur.

Wound subcutaneous tissue local infection can simple local drain, does not have secular troublesome problem.Yet more commonly wound infection usually can involve sticking patch.The hernia sticking patch usually needs to take out whole sticking patch when infecting.As only going the open drain of wound, may make the most of potentiality healing of wound, but sinus tract can occur or cause leaving in the wound residual cavity; And only dispel the part sticking patch, though also might effect a radical cure infection, cause that the recurrence probability of hernia increases; As not dispeling sticking patch, simple antibiotic therapy also is invalid.This shows, few for the infection problems way of disposing the hernia sticking patch clinically at present, and effect is bad.

Three, utility model content:

The purpose of this utility model provides a kind of silver-plated polypropylene mesh of medical antibacterial that can prevent that artificial sticking patch from infecting.

For reaching above-mentioned purpose, concrete scheme of the present utility model is: cover silver coating at existing polypropylene mesh outer surface, its structure still is the net lamellar.Its method is: (1) makes plain film with polypropylene for medical article net sheet, puts into the anhydrous alcohol solution oil removing.(2) the polypropylene for medical article net sheet after the oil removing is clean with distilled water flushing, the mixed liquor sensitization of putting into stannous chloride and concentrated hydrochloric acid.(3) the polypropylene for medical article net sheet after the sensitization is clean with distilled water flushing, put into by the silver ammino solution of 1: 1 proportional arrangement and the silver-plated 10～20min of mixed liquor of tartrate reducing solution.(4) with after the capable high pressure high temperature vapor sterilization treatment of silver-plated polypropylene for medical article net sheet, place vacuum tank to preserve, promptly get product.

Because silver particles can activate the oxygen in air or the water, produce hydroxyl radical free radical (OH) and active oxygen ion (O ₂ ^-), the multiplication capacity that they can the destroy microorganisms cell suppresses or kill bacteria.Silver particles as antibacterial, by the chemical silvering technology of tartrate as Reducing agent, is made the antibiotic net sheet of silver-plated polypropylene for medical article that can prevent that artificial sticking patch from infecting, make it have good antibacterial property, do not produce drug resistance, heat-resisting advantage such as strong.

Four, description of drawings:

Fig. 1 is a front view of the present utility model;

Fig. 2 is the A-A cutaway view of Fig. 1.

Five, the specific embodiment:

Please referring to Fig. 1, Fig. 2, this utility model mainly is made up of polypropylene mesh 1, silver coating 2, and its main points are, is coated with silver coating 2 at described polypropylene mesh 1 outer surface, and its structure still is the net lamellar.

Claims

1. the silver-plated polypropylene mesh of medical antibacterial comprises polypropylene mesh (1), it is characterized in that: be coated with silver coating (2) at described polypropylene mesh (1) outer surface, its structure still is the net lamellar.
