Abstract
A gathering-device for portable tube chamber eluent microorganism, belongs to the detection technique field of the Disinfection Effect of tube chamber class medical treatment device.This utility model devises the gathering-device of a tube chamber eluent microorganism that is portable, that close, and this device is made up of sample collection tube, residual liquid box, negative pressure pump storehouse, battery compartment four major part.Because conduit is that eluent can not along the wall of collecting pipe toward dirty, but flow directly on filter membrane to downward-extension shape; Meanwhile, due under the effect of negative pressure, filter membrane is also depression, and eluent can be stored within the scope of filter membrane, and can not encounter the tube wall of surrounding; So, eluent stream in sampling process can be reduced and, through the loss of tube wall, improve the concentrations of microorganism, more close to truth.Sampling process is closed, and considerably reduce the contaminated probability of sample, this device is portable, just can complete sampling at the scene.
Description
Technical field
A gathering-device for portable tube chamber eluent microorganism, belongs to the detection technique field of the Disinfection Effect of tube chamber class medical treatment device.
Background technology
The medical treatment device of a lot of tube chamber class is had for clinical treatment, as scope, catheter etc. in medical industry.These medical treatment device tube chambers are inner, and due to invisible, tube chamber is elongated, and cleaning difficulty is large, easily grows, the microorganism such as remaining bacteria, and the Disinfection Effect thus detecting tube chamber class medical apparatus and instruments has realistic meaning to minimizing clinical infection risk.The current Disinfection Effect method of sampling is mainly pure artificial sample, and sampling process is open, and sample is easily contaminated, can not reflect the Disinfection Effect of tube chamber exactly.Also have the enclosed peristaltic pump method of sampling, although sampling process is closed, considerably reduce the contaminated probability of sample, sample devices is heavy, substantially cannot sample at the scene.The present invention is directed to above shortcoming, devise the gathering-device of a tube chamber eluent microorganism that is portable, that close.
Summary of the invention
The purpose of this utility model is the gathering-device devising a portable, closed tube chamber eluent microorganism, for the detection of the Disinfection Effect of tube chamber class medical treatment device.
The technical solution of the utility model: the gathering-device of a kind of portable tube chamber eluent microorganism, this device is made up of sample collection tube (1), residual liquid box (2), negative pressure pump storehouse (3), battery compartment (4) four major part; Wherein sample collection tube (1) is made up of interface (5), conduit (6), filter element (7), sewer pipe (8), interface (5) lower end connecting duct (6), conduit (6) lower end is suspended from filter element (7), and conduit (6) the lower end mouth of pipe does not contact with sample collection tube (1) tube wall, filter element (7) lower end connects sewer pipe (8), filter element (7) intermediate recess, on be covered with filter membrane, filter membrane has certain elasticity, also recessed under the effect of negative pressure, collecting pipe (1) is sealed in plastic packaging bag after sterilization; Residual liquid box (2) is the plastic bottle that a top has a waste liquor stream import (9) and an air vent (10); Be the Miniature negative pressure pump (12) of 6 volts in negative pressure pump storehouse (3), the air entry of negative pressure pump is connected with a flexible pipe (11) with the air vent of residual liquid box (2), and a switch in order to control pump work (13) is equipped with in a side of negative pressure pump storehouse (3); Be No. 5 batteries of 1.5 volts of 4 joint series connection in battery compartment (4), power to negative pressure pump.
Open the plastic packaging bag of collecting pipe (1) during use, first interface (5) is connected the one end being sampled tube chamber, then open switch (13), now whole sealed tube intracavity is negative pressure state.Again filter element (7) is held level with both hands, eluent is injected in the tube chamber be sampled.Eluent flow to the filter membrane of depression through conduit (6) after the tube chamber be sampled flows out, and under the effect of negative pressure, eluent can be pumped down in residual liquid box (2), and microorganism is then enriched on filter membrane; Again interface (5) and sewer pipe (8) are pulled out, plastic packaging bag is sealed, residual liquid is poured out, completes the collection in worksite of a tube chamber eluate sample.
The beneficial effects of the utility model: because conduit (6) is that eluent along the wall of collecting pipe toward dirty, but can not flow directly on filter membrane to downward-extension shape.Meanwhile, due under the effect of negative pressure, filter membrane is also depression, and eluent can be stored within the scope of filter membrane, and can not encounter the tube wall of surrounding.So, eluent stream in sampling process can be reduced and, through the loss of tube wall, the concentrations of microorganism can be improved, more close to truth.And sampling process is closed, decreases pollution.
