Description

The used electrode of a kind of quick Skin allergy test device

Technical field

This utility model relates to the used electrode of a kind of quick Skin allergy test device.

Background technology

Along with increasing of types of drugs, different patients can be different to the adaptive capacity of medicine, also with regard to the corresponding irritated probability of patient that increased to the medicine generation, so, for some medicines before use, need carry out hypersensitive test.At present, the method for hypersensitive test has intracutaneous injection, scarification, eye dripping method, iontophoresis transdermal penetration method.

Tradition intracutaneous injection skin test is pain comparatively, needs observation in about 20 minutes, is difficult for accepting, and because of factors such as skilled operation degree or patient's spirit emotion easily cause erroneous judgement, can't takes out once injection, and is bigger to the quick patient's danger of height.

Iontophoresis transdermal penetration method use impulse electric field with medicine ion or charged medicine by the painless importing skin of electrode, make medicine by skin absorbs by following mechanism: a kind of is to enter corium through horny layer and epidermis to be absorbed by capillary tube; A kind of is to absorb by skin appendages; A kind of is electro-osmosis (stream) effect; A kind of is that electric field is induced and caused cutaneous permeability to increase.Make the skin test time only need 5 minutes, be easy to accept, advantages such as skin permeation of drugs speed is fast, result of the test is rapid, accuracy rate is high to have for it, painless, safety height are more and more accepted by medical industry.Adopt the quick Skin allergy test device of this method, generally comprise formations such as host computer control device, supply unit, pulse signal generation device, skin test electrode and skin electrode.

The electrode tip material of skin test electrode is directly made with copper in the Skin allergy test device of Shi Yonging in the market, and the surface is without any processing, and easily the oxidation pig copper becomes rusty in clinical use, causes the false alarm of skin test test.And the medicine carrying body in the design is directly to be cut into circularly and square with cotton, justifies cushion rubber and square cushion rubber independently is pressed on the copper electrode respectively with one.But this cotton can't directly absorb medicine and water for injection on dripping, the easy landing of medicine and water for injection.Sometimes can only pierce through the graticule of cotton with pin, just can absorb.And this cotton is owing to reuse, and very easily causes that copper electrode gets rusty, and do not meet the code requirement of nursing.

And the skin test electrode adopts three electrodes, be used for doing the hypersensitive test of penicillin and procaine simultaneously, and it are very little in the chance of the hypersensitive test at a position to do two kinds of medicines in actual clinical simultaneously, therefore should design and impracticable.

The utility model content

The purpose of this utility model is to provide a kind of minimizing false alarm rate, the used electrode of quick Skin allergy test device simple in structure and convenience is used, the skin electrode of this electrode is easy to place and change, safety and sanitation, and can improve medical work personnel's work efficiency.

In order to realize the purpose of this utility model, the used electrode of quick Skin allergy test device of the present utility model, it comprises plug, the electric wire that links to each other with described plug, described electric wire one end links to each other with an electrode tip holder, have two electrode tips on the described electrode tip holder, described skin electrode places on the described electrode tip, described skin electrode, comprise that one matches with described two electrode tip external surface shape respectively, and be placed in arc-spark stand base on the described electrode tip, two electrode cloth that are overlying on the described arc-spark stand base, two outer rings that fixedly are placed in respectively on the described electrode cloth.

Wherein, described two electrode tip shape differences.

Described two electrode tips are respectively square and circular.

Described electrode tip adopts chromed copper or stainless steel material, is difficult for producing oxidation and corrosion.

Described plug can link to each other with the control system main frame of quick Skin allergy test device, and under the effect of self adaptation pulse current, by electrode and the painless importing skin of skin electrode, described plug links to each other with two electrode tips on the electrode tip holder respectively by electric wire with medicine.

Described arc-spark stand base comprises two arc-spark stand base lassos and the connecting rod that is connected the two, and two arc-spark stand base lassos are connected as a single entity.

Described two arc-spark stand base lassos are respectively square and circular.

Described outer ring is similar to the shape of described arc-spark stand base lasso, plays electrode cloth fixed packet is overlayed on effect on the arc-spark stand base.

The fixed electrode cloth but match with described arc-spark stand base lasso in described like this outer ring, skin electrode becomes a medicated cap shape, but back-off is on two electrode tips of electrode tip holder.

Described electrode cloth is non-woven fabrics.

Each parts of the skin electrode of electrode described in the utility model closely cooperate, and make up as a wholely, are easy to place, medical personnel's work efficiency is greatly improved, use disposable electrode cloth, meet the nursing code requirement, not only absorb fast, evenly and avoid cross infection.

The used electrode of quick Skin allergy test device of the present utility model is difficult for producing oxidation and corrosion, has reduced the false alarm rate of skin test instrument; The skin electrode novel structure, be easy to place and change, safety and sanitation, and can improve medical work personnel's work efficiency, meet the nursing code requirement,, progressively enlarge the scope of application of painless quick irritated skin test medicine of the research and the clinical trial of the medicine of traditional irritated skin test by science, applicable to medicines such as penicillin, cephalo-type, TAT tetanus antitoxin, cytochrome C, allow the patient of more need skin tests be benefited.
