Aids sample processing device capable of automatically wiping hanging drops on side wall of sampling needle

Abstract

The invention provides an aids sample processing device capable of automatically wiping hanging drops on a side wall of a sampling needle. The device comprises a Beckman Coulter PrepPlus 2 processingdevice, a fixed base and two groups of automatic wiping mechanisms, the fixed base is arranged on a fixed main body of the sampling needle, the two groups of automatic wiping mechanisms are all arranged on the fixed base, each group of automatic wiping mechanisms comprises a pen-type electric push rod, a supporting bottom plate, a movable plate, an absorbent paper conveying mechanism and a push-pull electromagnet, the absorbent paper conveying mechanism comprises an absorbent paper roll, a first guiding roller, an absorbent paper pressing mechanism, a paper winding roller and a detection switch, the absorbent paper pressing mechanism comprises a pressing roller, a square rod, a pressing spring and a second driving motor, and the push-pull electromagnet is arranged on the supporting bottomplate. When a hanging drop phenomenon occurs on the side wall of the sampling needle, the two groups of automatic wiping mechanisms can automatically realize the wiping work of the hanging drops on the side wall of the sampling needle, and no manual wiping of a worker is needed, so that the worker can be liberated to do other works.

Description

technical field [0001] The invention relates to an AIDS sample processing device capable of automatically wiping the hanging drops on the side wall of a sampling needle. Background technique [0002] In the process of testing AIDS samples, due to the large number of testing samples required, some CDCs or hospitals now use Beckman Coulter PrepPlus 2 processing devices in order to reduce the work intensity of testing staff and improve the processing efficiency of samples. For sample processing, the Beckman Coulter PrepPlus 2 processing device can automatically complete the sampling and loading process of AIDS samples. During the sampling switching process, the sampling needle needs to be cleaned inside and outside. The existing Beckman Coulter PrepPlus 2 processing The device automatically cleans the sampling needle through its own cleaning device. However, after the sampling needle is cleaned and after the sampling needle is re-sampled, there will be drips on the side wall o...

Problems solved by technology

However, after the sampling needle is cleaned and after the sampling needle is re-sampled, there will be drips on the side wall of the sampling needle. When the side wall hanging drip occurs, the Beckman Coulter PrepPlus 2 treatment device will stop running and give an alarm to remind the staff to handle the side wall hanging drip. After the staff wipes the side wall hanging drip, the Beckman Coulter PrepPlus 2 The processing device started to work again. In the actual work process, the phenomenon of dripping on the side wall of the sampling needle often occurred, which made the sample processing work intermittent. Taking into account other tasks, at the same time, AIDS samples are contagious, the sampling needle is contaminated by the sample after sampling, and there are potential safety hazards when the staff manually handles the side wall hanging drops
