Uncapping device and vacuum test tube uncapping machine with uncapping device

Abstract

The invention discloses an uncapping device for a vacuum test tube uncapping machine. The uncapping device comprises an uncapping frame, an uncapping frame lifting and driving device, an uncapping plate, an uncapping plate driving device and an ejector rob; the uncapping frame comprises an upper uncapping frame and a lower uncapping frame; the uncapping plate is arranged between the upper uncapping frame and the down uncapping frame; through holes through which a test tube passes are distributed on the upper uncapping frame and the low uncapping frame; the number and the positions of the upper uncapping frame are in one-to-one correspondence with the number and the positions of the lower uncapping frame; uncapping driving gears which are driven by a motor to rotate are distributed on the upper uncapping frame; each uncapping gear is provided with a rubber ring; the inner diameter of the rubber ring is so large that the rubber ring can be rightly sleeved on the cover of the test tube; and each uncapping gear corresponds to one through hole on the upper uncapping frame and the uncapping gear is arranged on the through hole. The invention discloses the vacuum test tube uncapping machine with the uncapping device. The uncapping device has the advantages of simple structure, low cost, small volume, high safety, and high efficiency and is easy to manufacture and can open vacuum test tubes with screw covers and straight covers.

Description

Technical field [0001] The invention relates to the technical field of decapping of vacuum test tubes, in particular to a capping device and a vacuum test tube decapping machine provided with the capping device. Background technique [0002] As a medical clinical test, it is the most common way to collect blood in a vacuum test tube as a test sample. After the blood is collected with a vacuum test tube, there is still a certain negative pressure in the vacuum test tube, and the close fit between the test tube cover and the test tube wall makes the test tube cover (or test tube cap) still firmly fixed on the test tube. It takes more effort to pull off the test tube cover. When vacuum test tubes are widely used, this kind of work of opening the test tube cover becomes a relatively heavy manual labor. Vigorously opening the lid of the test tube will also produce internal oscillations in the test tube, which may mix up the samples that have been centrifuged, affecting some test re...

AI Technical Summary

Problems solved by technology

The decapping machine has the advantages of small size, simple structure, high efficiency, strong practicability, good safety and low manufacturing cost; but it still cannot meet the needs. According to different manufacturers, there are straight caps without threads (ie The cap and the test tube are fixed by interference fit) and the screw cap with thread, the above-mentioned cap remover can only open the vacuum test tube with the straight cap, but not the test tube with the screw cap
