Abstract
The utility model relates to a qualitative detecting device for residual proteins, and the qualitative detecting device is used for carrying out cleanness detection on medical devices, and comprises a plastic cap, a bottom-sealed plastic tube and swabs, wherein the swabs are arranged in the bottom-sealed plastic tube, and the upper opening of the bottom-sealed plastic tube is equipped with the plastic cap. The qualitative detecting device provided by the utility model has the advantages of simple structure, good detection effect, low cost, strong maneuverability, and no damage and secondary pollution on apparatuses, and is convenient to use.
Description
Technical field
The utility model relates to the residual qualitative detection device of a kind of protein, is used for the cleaning of medicine equipment is detected.
Background technology
The World Health Organization (WHO) recommends to point out in the principle to the cleaning and sterilizing of apparatus, carries out the steps necessary that preliminary cleaning is sterilization to polluting apparatus.What is " cleaning " actually, does not still have unified standard at present in the world.The method of the cleaning performance of home and abroad evaluation at present is except that visual method, and main also have: the method that 1. detects organic contaminant: occult blood experiment, blue light experiment, copper sulphate-albuminometry; 2. detect microbial process: the microbe growth counting method; 3. detect organic contaminant and method of microorganism simultaneously: ATP bioluminescence method.And protein residue detection wherein is the most quick, the most stable, that operability is best a kind of method, and hospital supply room does not also have rational protein residue detection device at present.
The utility model content
The purpose of this utility model is to provide a kind of protein residual qualitative detection device, and is simple in structure, easy to use, detects effectively, and cost is low.
The residual qualitative detection device of protein described in the utility model comprises plastic cap, back cover plastic tube and cotton swab, and cotton swab places the back cover plastic tube, the plastic cap that is fitted with suitable for reading of back cover plastic tube.
Between plastic cap and back cover plastic tube multiple connected mode can be arranged, be fastened and connected, be threaded etc., be threaded better, the better seal effect is arranged as tensioner.
In the utility model, cotton swab preferably uses aseptic absorbent cotton and sticking plaster, and plastic cap and back cover plastic tube material therefor need tolerate 100 ℃ temperature.
During use, 0.1% ethanol solution of ninhydrin of packing in back cover plastic tube colour developing liquid is with till the submergence cotton swab lower end absorbent cotton just.After using the Swab Wiper tool, put into the back cover plastic tube, the cotton swab lower end is immersed in the colour developing liquid, screw plastic cap then, integral body is placed in the incubator heats, temperature is 75-85 ℃, observe colour developing liquid change color, if the apparatus surface has protein residual, can be through the color of heating back colour developing liquid by the xanthochromia purple, on the contrary then there is not change color.
The residual qualitative detection device of the utility model protein, simple in structure, easy to use, detect effectively, cost is low, and is workable, and to apparatus not damaged and secondary pollution.
Description of drawings
Fig. 1, the utility model one example structure synoptic diagram.
Among the figure: 1, plastic cap 2, back cover plastic tube 3, cotton swab.
Embodiment
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing.
As shown in the figure, the residual qualitative detection device of protein described in the utility model comprises plastic cap 1, back cover plastic tube 2 and cotton swab 3, and cotton swab 3 places back cover plastic tube 2, the plastic cap 1 that is fitted with suitable for reading of back cover plastic tube 2, plastic cap 1 is threaded with 2 of back cover plastic tubes.
During use, 0.1% ethanol solution of ninhydrin of packing in back cover plastic tube 2 colour developing liquid is with till the submergence cotton swab 3 lower end absorbent cotton just.After using cotton swab 3 wiping apparatus, put into back cover plastic tube 2, cotton swab 3 lower ends are immersed in the colour developing liquid, screw plastic cap 1 then, integral body is placed in the incubator heats, temperature is 75-85 ℃, observe colour developing liquid change color, if the apparatus surface has protein residual, can be through the color of heating back colour developing liquid by the xanthochromia purple, on the contrary then there is not change color.
