Problems solved by technology

For the horizontal plate washer, the microplate is placed horizontally in the plate washer. When the waste liquid is not collected in time, or even the liquid injection tube is too strong, it will cause the overflow of the well of the microplate and the sample detection. cross-infection; for vertical plate washer, during the cleaning process, the microplate plate is placed vertically, and no liquid is sucked during washing. In theory, the waste liquid flows downward due to gravity, and there is a risk of cross-infection between the wells of the microplate plate

Embodiment 1

[0024] Such as figure 1 As shown, it is a protective cover for cleaning the microplate plate. A number of overflow-proof extension tubes 1 are arranged on the enzyme-label plate cleaning protection cover 3. The upper and lower ends of the overflow-proof extension tube 1 are open. and the positions are respectively one-to-one corresponding to the quantity and position of the microplate plate holes 5, and the length of the anti-overflow extension tube is twice the depth of the microplate plate wells. The lower port of the anti-overflow extension tube 1 can be in sealing contact with the orifice of the microplate plate hole 5 through the O-shaped sealing ring 2, or a sealing groove is provided at the lower end of the microplate plate protective cover, and the microplate plate 6 is placed on the tray 7 Above, the microplate cleaning protective cover 3 , microplate plate 6 and tray 7 are sequentially attached and fixed by the fixing device 4 , and in this embodiment, the fixing cli...

Embodiment 2

[0026] Such as figure 2 As shown, it is a plate washer comprising a microplate plate cleaning protection cover 3, and also includes a plate washer cavity 11, a tray 7 and a first cleaning head 8, and the first cleaning head 8 is provided with a liquid injection pipe 9 and a suction pipe. Liquid pipe 10. The fixing device 4 fits and fixes the microplate cleaning protection cover 3, the microplate 6 and the tray 7 in sequence, injects the washing liquid into the hole 5 of the microplate plate from the liquid injection pipe 9 to soak, and then uses the pipette to soak. 10 Aspirate the waste liquid.

Embodiment 3

[0028] Such as image 3 and 4 As shown, it is a plate washer including a microplate plate cleaning protection cover 3, including a plate washer cavity 11, a tray 7 and a first cleaning head 8, and the first cleaning head 8 is provided with a liquid injection tube 9 and a liquid suction pipe. Tube 10. It also includes a first cleaning head 8 , a lifting device 14 and a plate washer cavity 11 . Also comprise the second cleaning head 15, sliding block 13 and sliding shaft 12, the first cleaning head 8 and the second cleaning head 15 are respectively fixed on the lifting device 14, and the lifting device 14 is located on the sliding block 13, and the sliding block 13 can Do axial movement on the sliding shaft 12, the sliding shaft 12 is arranged on the top of the plate washer cavity 11, the second cleaning head 15 is provided with a cleaning pipe 16, and the inside of the cleaning pipe 16 is provided with a rotating shaft 17, and the rotating shaft 17 Extending from the end por...

Abstract

The present invention discloses an ELISA plate cleaning protective cap and a plate washer. A plurality of anti-overflow extension tubes are arranged on the ELISA plate cleaning protective cap; upper and lower ends of each anti-overflow extension tube is opened; the number and positions of the anti-overflow extension tubes are respectively corresponding to the number and positions of ELISA plate holes; the anti-overflow extension tubes are in seal contact with the ELISA plate hole tops to prevent liquid leakage at positions where the anti-overflow extension tubes are in contact with the ELISA plate hole tops; an ELISA plate is disposed on a tray; and the ELISA plate cleaning protective cap, the ELISA plate and the tray are sequentially attached and fixed through fixing clamps. During a conventional cleaning work process of the plate washer equipped with the ELISA plate cleaning protective cap, when imbibitions of pipettes is not timely or not thorough, even when liquid injection intensity of liquid injection tubes is large, liquid containing capabilities of the ELISA plate holes can be increased due to the fact that the anti-overflow extension tubes are installed, liquid overflow of the ELISA plate holes can be effectively prevented, and cross infection risks can be reduced.

Description

technical field [0001] The invention relates to a cleaning device for medical detection and analysis, in particular to a protective cover for cleaning an enzyme label plate and a plate washer. Background technique [0002] The plate washer is the auxiliary equipment of the microplate reader. It is a medical device specially used for cleaning the microplate. It plays an important role in the cleaning of the microplate in hospitals, blood stations, health and epidemic prevention stations, reagent factories, and research laboratories. effect. The plate washer in the prior art can be simply divided into horizontal plate washer and vertical plate washer. For a horizontal plate washer, the microplate is placed horizontally in the plate washer. When the waste liquid is not collected in time, or even the liquid injection tube is too strong, it will cause overflow of the wells of the microplate and sample detection. cross-infection; for vertical plate washer, during the cleaning pr...
