Description

A kind of medical cleaning of enzyme liquid quantifier

Art

This utility model relates to technical field of medical instruments, especially relates to a kind of medical cleaning of enzyme liquid quantifier.

Background technology

Along with the development of endoscopic technic in the clinical treatment of hospital, the cleaning and sterilizing of scope is increasingly becoming the medical Important Problems of concern.Endoscopic technic focuses on cleaning and sterilizing flow process, is especially focused on cleaning link, cleans in link and scrubs, with the enzyme immersion bubble that proportioning is good, the important step being to remove pollutant.Generally hospital's enzyme liquid consumption is big, one barrel of enzyme liquid has 4 liters, weight about 4KG, enzyme liquid used needs to carry out proportioning, and needs people one replacing, and prior art is typically all with graduated cylinder stoichiometry enzyme liquid consumption, it is repeatedly opened closedown enzyme liquid bucket and is likely to increase the chance of pollution, and use depressor to draw enzyme liquid, can only probably estimate consumption, it is difficult to ensure that enzyme liquid matched proportion density is correct.Using graduated cylinder stoichiometry then to operate to waste time and energy, to cleaning operation, personnel increase workload.A kind of simple in construction of research and development, proportioning enzyme liquid is convenient, accurate measurement, it is to avoid it is loaded down with trivial details that Reusability graduated cylinder weighs, and also avoid being repeatedly opened enzyme fluid cylinder increases the medical cleaning of enzyme liquid quantifier of opportunities for contamination simultaneously, is the current the art task of being badly in need of.

Summary of the invention

The purpose of this utility model is to provide a kind of simple in construction, accurate measurement, the medical cleaning of enzyme liquid quantifier that proportioning enzyme liquid facilitates and avoids enzyme liquid to pollute.

nullIn order to achieve the above object，This utility model following structure of employing: a kind of medical cleaning of enzyme liquid quantifier，By nozzle、Squeeze grip、Drain pipe、Bottle cap、Steam vent、Piston、Spring、Liquid storage cylinder、Liquid flowing valve and catheter composition，It is characterized in: hollow circular tube squeeze grip one end bending cantilever constitutes nozzle，The other end L-shaped right angle connection hollow drain pipe，Hollow drain pipe outer round surface is provided with scale，The hollow drain pipe other end connects hollow piston after coordinating the centre bore inserting bottle cap，Bottle cap screwing is in cylinder liquid storage cylinder one end，And to the piston limit in liquid storage cylinder，Piston periphery seals the steam vent on liquid storage cylinder surface，Piston tip connects helical spring one end，The helical spring other end is stuck in cylinder liquid storage cylinder on the boss of the other end，The narrow mouth connection catheter that boss indent is formed，The spherical narrow mouth of liquid flowing valve fitted seal，Constitute medical cleaning of enzyme liquid quantifier.

Scale value scope on hollow drain pipe outer round surface described above is 7.5ml 22.5ml.

Operation principle of the present utility model is: be the movement utilizing piston to discharge the air in liquid storage cylinder, cause inner and outer air pressure poor, and make liquid rise from drain pipe outside discharge pipe under gas pressure.When being pressed downward against squeeze grip, due to tube chamber hollow, air extrudes from nozzle, negative pressure is formed in tube chamber, after unclamping squeeze grip, enzyme liquid is full of liquid storage cylinder tube chamber at atmosheric pressure, again press squeeze grip, the plunger forces spring of drain pipe lower end moves down, now the steam vent on liquid storage cylinder is opened, block under the pressure effect of liquid due to the steel ball of liquid flowing valve and bottom liquid storage cylinder tube chamber, prevent enzyme liquid reflux, enzyme liquid can only flow out from nozzle, the amount flowed out and the distance of squeeze grip are directly proportional, thus can read, by the scale on drain pipe, the amount that enzyme liquid stream goes out.When again unclamping squeeze grip, spring recovers original naturalness so that piston moves up blocks steam vent, and liquid flowing valve steel ball is backed down simultaneously, and under the effect of external atmosphere pressure, liquid enters into liquid storage cylinder from catheter by liquid flowing valve.Piston pumps within the barrel, constantly enzyme liquid is sucked liquid storage cylinder and is flowed out by nozzle, and enzyme liquid stream output is measured as required by the metering scale at drain pipe and is controlled.

Due to have employed above-mentioned utilize piston move make liquid storage cylinder in produce the structural principle of structure extraction enzyme liquid of draught head, this utility model simple in construction, accurate measurement, proportioning enzyme liquid is convenient, avoid the loaded down with trivial details of Reusability graduated cylinder weighing, it also avoid simultaneously and be repeatedly opened enzyme fluid cylinder increase opportunities for contamination, reached goal of the invention.
