Uncapping machine with function of automatically uncapping single blood collection tube

Abstract

The invention relates to an uncapping machine with the function of automatically uncapping a single blood collection tube. The uncapping machine comprises a baseplate and a standing plate perpendicularly and fixedly connected with the baseplate, wherein a lifting device, a clamping device and an uncapping device are arranged on the standing plate; the clamping device comprises a mounting plate and a clamping motor which are fixedly connected to the back side of the standing plate; a driving gear is arranged on the motor shaft of the clamping motor; two driven gear in meshing connection with each other are mounted on the mounting plate; the driving gear is in meshing connection with one driven gear; core shafts, of which the outer ends extend to the front side of the standing plate, are arranged in the centers of the two driven gears; clamping blocks are arranged at the end parts of the core shafts; the uncapping device comprises an uncapping motor fixedly connected with the standing plate; the outer end of the motor shaft of the uncapping motor extends to the front side of the standing plate and is provided with a connecting block; a U-shaped shifting piece is mounted on the connecting block; a strip-shaped through hole is formed in the middle of the shifting piece; the width of the inner end of the through hole is greater than the diameter of the tube cap of the blood collection tube; the width of the outer end of the through hole is greater than the diameter of the tube body of the blood collection tube and smaller than the diameter of the tube cap.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a cap uncapping machine with the function of automatically uncapping a single tube of a blood collection tube. Background technique [0002] Vacuum blood collection tubes are a common product in the field of modern medicine and are used to store blood samples. It is necessary to open the cap of the blood collection tube before sampling and testing. Since the tube is always in a negative pressure state, it will be laborious to directly uncap the cap by hand. Therefore, a cap unscrewing machine appears on the market to assist medical personnel in the inspection of the blood collection tube. Uncap. The existing cap opening machine equipment is generally in the form of multi-tube cap opening, that is, it includes a multi-station turntable, and a plurality of blood collection tube caps are inserted circularly upwards on the stations of the turntable, under the control of ...

AI Technical Summary

Problems solved by technology

The cap unscrewing machine with the above structure is suitable for the situations and occasions of large-scale operation. For a relatively small amount or even a single case of uncapping a blood collection tube, the multi-tube cap unscrewing machine with the above structure will increase the cumbersome operation. degree and waiting time

At the same time, the structure of the above-mentioned multi-pipe cap opening machine is relatively complicated, and there are many moving parts, so it is prone to failure during operation
