Sample rack recovery device

Abstract

The invention discloses a sample rack recovery device which comprises a base and a pusher unit, wherein a mounting plate is fixedly connected onto the base; a fixed bearing unit and a movable basket bearing unit are arranged on the inner side of the mounting plate; the fixed bearing unit comprises a first bearing plate; a first guide rail is arranged on a bottom plate of the first bearing plate; the movable basket bearing unit comprises a second bearing plate and a handle assembly; a second guide rail is arranged on the second bearing plate; the handle assembly comprises a U-shaped frame; and a handle is upwards vertically arranged at a bend of the U-shaped frame. According to the sample rack recovery device disclosed by the invention, the fixed bearing unit and the movable basket bearing unit are arranged at an interval, the sample rack enters the second bearing plate through the first bearing plate, and after the movable basket bearing unit is full, the sample rack can be taken out. In-vitro diagnostic equipment does not need to be stop working in the taking-out process, the working efficiency is improved, the labor intensity of workers is reduced, the operating convenience is improved, and risk of interference on instrument operation due to stopped operation caused by repeatedly taking-out is avoided.

Description

technical field [0001] The invention relates to an auxiliary transmission system of in vitro diagnostic equipment, in particular to a sample rack recovery device in the auxiliary transmission system of in vitro diagnostic equipment. Background technique [0002] In the field of in vitro diagnostic testing, the transmission system of automatic analysis instruments (such as biochemical analyzers, chemiluminescence meters, urine meters, nucleic acid meters, etc.) is composed of automatic sample delivery and recovery devices. The existing recovery device pushes the sample rack forward by a sample rack position through the pusher. When the recovery bin is full, the sample rack can only be taken out manually many times due to the lack of basket function. There is a risk of interfering with the operation of the instrument when taking it out once, which reduces the efficiency of the instrument. When the sample rack is moved after taking it out, there is a risk of the sample rack fal...

Problems solved by technology

The existing recovery device pushes the sample rack forward by a sample rack position through the pusher. When the recovery bin is full, the sample rack can only be taken out manually many times due to the lack of basket function. There is a risk of interfering with the operation of the instrument when taking it out once, which reduces the efficiency of the instrument. When the sample rack is moved after taking it out, there is a risk of the sample rack falling off due to the manual operation. recovery device, but the sample rack can only be taken out after the instrument is suspended, and more sample racks are taken out at one time, which is laborious and inconvenient for manual operation

The above two recovery devices are easy to dump when the sample rack is pushed, which will cause waste samples to fall on the tray, increase the workload, and cause biological hazards

Most of the driving mechanisms used in the above-mentioned recovery devices are synchronous belt transmission mechanisms without self-tensioning effect. Generally, the tension degree of the synchronous belt is adjusted by adjusting the positional relationship between the driving and driven wheels. The adjustment process is cumbersome, and it is easy to The phenomenon of slipping and shaking caused by the slack of the synchronous belt seriously affects its transmission accuracy, shortens the maintenance cycle and increases the maintenance cost
