According to the needle washing groove disclosed by the utility model, secondary pollution due to the contact between sampling needles and a cleaning liquid in the liquid storage tank can be avoided; the needle washing groove can be suitable for medical treatment equipment with a plurality sampling needles; and the cross contamination among the sampling needles can be avoided, so that a better cleaning effect of the sampling needles is obtained and further the accuracy of detection is improved.
Description
Technical field
The utility model relates to the Medical Devices technical field, particularly a kind of needle tray of washing.
Background technology
In various medical detecting Instruments, particularly in enzyme non-analysis meter and the chemiluminescent analyzer, often need to use sample needle, be used for drawing the reagent such as sample, enzyme or distilled water, thereby be used for carrying out various tests.After drawing each reagent, usually all need sample needle is washed.Washing needle tray is the container that cleans for sample needle.
The existing needle tray of washing mostly is ampuliform or cylindrical container, after in this container, installing cleaning fluid additional, sample needle is directly put into this and is washed the needle tray washing, such wash result is unsatisfactory, because sample needle is immersed in the cleaning fluid always, and the existing various reagent that wash on a small quantity in the cleaning fluid can carry out secondary pollution to sample needle, so that the cleaning of sample needle is not thorough, thereby affect testing result.
The utility model content
Main purpose of the present utility model is, for above-mentioned deficiency of the prior art, provides a kind of needle tray of washing, and can promote the cleaning performance of sample needle, avoids sample needle to be repeated to pollute or cross pollution, improves the degree of accuracy that detects.
For achieving the above object, the utility model by the following technical solutions.
The utility model provides a kind of needle tray of washing, comprise body, described body comprises four sidewalls, and the liquid storage tank that is surrounded by described four sidewalls and a base plate, be provided with step on a described sidewall therein, offer at least one regurgitate hole at described step, described at least one regurgitate hole is horizontal linear and arranges.
Preferably, described regurgitate hole is four, and is provided with division board between each described regurgitate hole.
Preferably, described regurgitate hole is cylindrical.
Preferably, the bottom in described regurgitate hole is hemispherical.
Preferably, between described sidewall and the sidewall, be connected for arcwall face between sidewall and the base plate.
Preferably, described liquid storage tank is provided with discharge outlet.
Than above-mentioned prior art, the utlity model has following advantage.
The needle tray of washing of the present utility model arranges the regurgitate hole at sidewall, and sample needle is directly washed in the regurgitate hole, the cleaning fluid after the flushing is flowed in the liquid storage tank, and by the discharge outlet that is arranged in the liquid storage tank waste liquid is discharged.And, between each regurgitate hole, be provided with division board.So design, not only can avoid sample needle to contact with cleaning fluid in the liquid storage tank and cause secondary pollution, also go for having the Medical Devices of a plurality of sample needles, and can prevent the cross pollution between a plurality of sample needles, make the cleaning performance of sample needle better, thereby improve the degree of accuracy that detects.

The realization of the utility model purpose, functional characteristics and advantage are described further with reference to accompanying drawing in connection with embodiment.
The specific embodiment
Describe the technical solution of the utility model in detail below with reference to drawings and the specific embodiments, so as clearer, understand invention essence of the present utility model intuitively.
Fig. 1 is the overall structure schematic diagram of washing needle tray among the utility model embodiment; Fig. 2 is the sectional structure schematic diagram of washing needle tray among the utility model embodiment.
The present embodiment provides washes needle tray, is mainly used in enzyme non-analysis meter or other Medical Devices sample needle being cleaned.
Shown in seeing figures.1.and.2, the needle tray 100 of washing of the present embodiment comprises body 1, body 1 comprises four sidewalls 11, and the liquid storage tank 2 that is surrounded by these four sidewalls 11 and a base plate 12, on a sidewall 11 step 3 is set therein, offer at least one regurgitate hole 4 at this step 3, be used for sample needle is washed.
Particularly, regurgitate hole 4 can be set to one, two, three, four or more, be adapted to have one, two, three, four or more the Medical Devices of sample needle.Wherein, if when regurgitate hole 4 is two or more, also be provided with division board 5 between each regurgitate hole 4, the effect of this division board 5 is in the process that sample needle cleans, to prevent from forming cross pollution between the adjacent sample needle, thereby affect cleaning performance.
The regurgitate hole 4 of the present embodiment is cylindrical, and, the bottom in regurgitate hole 4 is set to hemispherical, like this, when cleaning fluid is penetrated from the sample needle high speed, cleaning fluid through domed bottom along cylindrical side regurgitate facing up, thereby the outer wall of sample needle is washed away, so that sample needle is cleaned thoroughly, can further improve the cleaning performance of sample needle.
Simultaneously, be provided with discharge outlet 21 in the bottom of liquid storage tank 2, this discharge outlet 21 can be arranged in above-mentioned four sidewalls 11, also can be arranged at above-mentioned base plate 12.Like this, on the one hand, this liquid storage tank 2 can hold the cleaning fluid that spills in the regurgitate hole 4, on the other hand, when the discharge pipe line in regurgitate hole 4 stops up, also can hold the waste liquid that cleans behind the sample needle, prevents that waste liquid from overflowing.Behind liquid storage tank 4 long-pending full waste liquids, can discharge by above-mentioned discharge outlet 21, very convenient and practical.
To wash needle tray 100 and be convenient to clean in order to make, the present embodiment is also with between sidewall 11 and the sidewall 11, and is designed to arcwall face between sidewall 11 and the base plate 12 and is connected, make between the sidewall 11 and sidewall 11 and base plate 12 between be arc-shaped transition.So, on the one hand can avoid liquid storage tank 4 interior formation dead angles, so that clean more totally and convenient, also can reduce on the other hand between the sidewall 11, the stress between sidewall 11 and the base plate 12, thereby make the withstand voltage and anti-performance of falling of washing needle tray 100 better, effectively prolong the service life of washing needle tray 100.
In sum, the needle tray of washing of the present utility model arranges the regurgitate hole at sidewall, and sample needle is directly washed in the regurgitate hole, cleaning fluid after the flushing is flowed in the liquid storage tank, and by the discharge outlet that is arranged in the liquid storage tank waste liquid is discharged, and, between each regurgitate hole, be provided with division board.So design, not only can avoid sample needle to contact with cleaning fluid in the liquid storage tank and cause secondary pollution, also go for having the Medical Instruments of a plurality of sample needles, and can prevent the cross pollution between a plurality of sample needles, make the cleaning performance of sample needle better, thereby improve the degree of accuracy that detects.
The above only is preferred embodiment of the present utility model; be not so limit its claim; every equivalent structure transformation that utilizes the utility model specification and accompanying drawing content to do; directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
