Abstract

The utility model discloses an EIA reagent board cleaning device for detecting HBsAg, ATHBS, HbeAG, ATHBE and ATHBC, which is composed of clamping grooves 1 and 2, a box body 3, a circular tube 4 which also serves as a piston cavity, and a reservoir 9. The utility model is characterized in that the clamping grooves 1 and 2 are sliver-shaped grooves for fixing reagent plates; the end face 10 of the box body 3 is provided with micropores which correspond with the 6 holes multiple 4 reagent plates; a reducing pipe 6 of which the interior is provided with a one way cut-off valve 11 on the lower wall of the circular tube is connected with the reservoir 9 via a rubber pipe 8, and the path can be controlled by the one way cut-off valve 11; when a switch 5 is turned on and a piston 7 is pushed, washing liquid in the piston cavity 4 is shot into the corresponding holes on the reagent plate from the end face 10. The utility model has the advantages that the plate washing does not need multiple steps, and the purpose of washing the plate is achieved.

Description

Detect two double EIA agent plate plate washing devices

The utility model belongs to a kind of two EIA agent plate plate washing devices of double that detect.

At present in detecting two double the flushing work of EIA agent plate, modal is to wash plate by hand, discards the liquid hole in that is:, and cleaning solution is filled with in the hole, and static five seconds, drying drained after repeating five times.In this process, it is more to wash the plate number of times, and directly contacts serum.Another kind of more rare for washing plate machine washing plate, though can realize controlling automatically washing plate, more convenient.But, owing to cost an arm and a leg all unable purchase of a lot of units in actual applications.

The purpose of this utility model provides a kind of two EIA agent plate plate washing devices of double that detect, and it can not only solve loaded down with trivial details washing plate and directly contact this technical barrier of serum effectively, and can reach the purpose of washing plate.

To achieve these goals, this uses novel detection two double EIA agent plate plate washing devices to be made up of trapezoidal box body, draw-in groove, the pipe, piston, reduced pipe and the reservoir that have a ground switch double as plunger shaft.The end face thin-walled of trapezoidal box body contains and 6 holes * corresponding micropore in each hole of 4 agent plate.

The trapezoidal box body two side links to each other with draw-in groove 2 with draw-in groove 1, and draw-in groove 1 and draw-in groove 2 can vertically insert 1/2 of 8 holes * 6 agent plate, 1/2 long strip type groove of laterally inserted 12 holes * 4 agent plate.Therefore, all applicable for the agent plate of 12 holes * 4 common on the market, 8 holes * 6,6 holes * 4 three kind of specification.

The trapezoidal box body rear end links to each other with the pipe of a band ground switch double as plunger shaft, and the pipe lower wall communicates with the reduced pipe of a built-in unidirectional stop valve.Unidirectional stop valve in the reduced pipe can be controlled path between reservoir and the plunger shaft by the positive and negative pressure in the plunger shaft.

Because adopting the draw-in groove specification is the such structures in 6 holes * 4, therefore, it is all applicable to detect two double EIA agent plate for three kinds of common on market specifications; Again because after the ground switch cuts out, the pulling piston, the negative pressure that produces in the plunger shaft can be with cleaning solution sucker chamber, open switch this moment, promote piston under external force, unidirectional stop valve in the reduced pipe will be towards the path blockade of reservoir, and liquid is injected in the draw-in groove in the corresponding hole of agent plate from the micropore on the trapezoidal box body end face thin-walled.

Be described in further detail this use is novel below in conjunction with the drawings and specific embodiments.

Fig. 1 is that this uses novel detection two double the schematic diagrames of the specific embodiment of EIA agent plate plate washing device.

Fig. 2 is the partial top view of trapezoidal box body A-A '.

Detection shown in Figure 1 two double EIA agent plate plate washing devices are made up of draw-in groove 1, draw-in groove 2, the pipe 4 that has ground switch 5 double as plunger shaft, piston 7, reduced pipe 6, sebific duct 8 and reservoir 9.Draw-in groove 1 and draw-in groove 2 can vertically insert 1/2 of 8 holes * 6 agent plate respectively, 1/2 strip groove of laterally inserted 12 holes * 4 agent plate.Unidirectional stop valve 11 in the reduced pipe 6 can be by positive and negative pressure control piston chamber 4 in the plunger shaft and the path between the reservoir 9.

Detection shown in Figure 2 two double the vertical views of EIA agent plate plate washing device trapezoidal box body, wherein box body 3 end faces 10 have and the 6 holes * corresponding micropore in each hole of 4 agent plate--24 holes.From then on cleaning solution is promptly injected in the interior agent plate respective aperture of draw-in groove.

When washing plate, as use 6 holes * 4 agent plate once to insert to wash; As use the agent plate of 8 holes * 6 or 12 holes * 4, can vertical or horizontal insertion half, 1/2 of each wash reagent plate.Again switch 5 cuts out, pulling piston 7, the negative pressure that produce in the plunger shaft 4 make reduced pipe 6 inner gateways open, by sebific duct 8 with in the cleaning solution sucker chamber 4, again switch 5 is opened, under external force, the stop valve 11 that promotes in piston 7 reduced pipes 6 will be towards the path blockade of reservoir 9, and liquid is injected from the micropore of the end face 10 of box body 3 and will be washed in the corresponding hole of agent plate, repeat 5 times, pat dry.Promptly reach the purpose of washing plate, and solved numerous rope and wash plate and directly contact this technical barrier of serum.
