A blood collection tube transportation device and its control method

Abstract

The invention provides blood collection tube conveying equipment which comprises a placement disc, a plurality of squeezing and conveying devices and a conveying device. The squeezing and conveying devices are rotationally supported on the placement disc. Each squeezing and conveying device comprises forward rotating shafts rotationally supported on the placement disc and provided with forward threaded grooves in the surfaces, and reverse rotating shafts rotationally supported on the placement disc and provided with reverse threaded grooves in the surfaces, wherein the reverse rotating shaftsare parallel to the forward rotating shafts, containing spaces for a plurality of blood collection tubes are formed between the forward threaded grooves and the reverse threaded grooves, the rotatingdirection of the forward rotating shafts is opposite to the rotating direction of the reverse rotating shafts, and the blood collection tubes can be squeezed to move in the axial direction of the rotating shafts. The conveying device is arranged at one end of the placement disc, and the blood collection tubes can be conveyed from one end of the conveying device to the other end. The invention further provides a control method of the blood collection tube conveying equipment.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a blood collection tube transportation device and a control method for the blood collection tube transportation device. Background technique [0002] Blood tests are widely used as a medical diagnostic method. Hospitals usually set up separate blood collection stations for centralized blood collection and testing of patients. Blood collection stations often need to collect tens of thousands of blood samples every day. With the research and use of automatic blood collection devices, there is an urgent need for equipment that can automatically transfer blood collection tubes. Blood collection equipment, and can classify and transport blood collection tubes according to blood collection items. [0003] The patent application document with the application number 201810612750.2 discloses a blood collection tube sorting device and a transmission mechanism. Through the combination of the...

AI Technical Summary

Problems solved by technology

Since the blood collection tubes are prone to sticking and other phenomena in the above technical solutions, the operation time is long, the structure is more complicated, and the efficiency is also low. Further improvement is needed to solve the problems of low efficiency and poor reliability of traditional manual sorting operations.
