A cover opening and closing structure of a vacuum blood collection tube opening and closing machine

Abstract

The invention discloses a cap opening and closing structure of a vacuum blood collection tube cap opening and closing integrated machine. A movable mounting rack which is driven by a lifting driving mechanism is arranged on a front end side of a fixed supporting vertical plate, and comprises a middle movable rod, a left movable rod and a right movable rod; a movable plate between the left movable rod and the right movable rod is provided with a blood collection tube cap clamping assembly, and is driven by a feeding and discharging driving mechanism; the blood collection tube cap clamping assembly comprises an upper end clamping plate and a lower end clamping plate; a right driving flange is arranged at the edge of the right end of the upper end clamping plate; a left driving flange is arranged at an edge of the left end of the lower end clamping plate; a releasing and clamping driving mechanism between the left movable rod and the right movable rod is respectively connected with the left driving flange and the right driving flange in a driving manner; a left tube cap clamping block is arranged on the side wall of the left end of a clamping plate through hole of the lower end clamping plate; a right tube cap clamping block is arranged on the lower surface of the upper end clamping plate; and compression springs are clamped between the upper end clamping plate and the lower end clamping plate. Through the structural design, the cap opening and closing structure of the vacuum blood collection tube cap opening and closing integrated machine has the advantages of novel design, reasonable structure, high automation degree and good stability and reliability.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a cover opening and closing structure of a vacuum blood collection tube opening and closing machine. Background technique [0002] Vacuum blood collection technology was invented in the late 1930s. This technology has the advantages of convenient clinical use, simple operation, fully enclosed test tube, biological safety, easy repeated inspection of specimens, and easy preservation of specimens, and is basically popularized and applied nationwide. Laboratory vacuum blood collection tube specimens generally require processing before analysis, such as biochemical specimens, which go through the steps of collection, centrifugation, cap opening, inspection, cap closure, preservation, and disinfection. The entire process is labor-intensive and cumbersome, so the process needs to be optimized , Improve efficiency and reduce labor intensity. [0003] At present, the opening of ...

Laboratory vacuum blood collection tube specimens generally require processing before analysis, such as biochemical specimens, which go through the steps of collection, centrifugation, cap opening, inspection, cap closure, preservation, and disinfection. The entire process is labor-intensive and cumbersome, so the process needs to be optimized , improve efficiency and reduce labor intensity

[0003] At present, the opening of vacuum blood collection tubes in medical laboratories is mostly done manually by medical staff. There is no medical staff to close the caps on the patient specimens that have completed the inspection work, and there is no equipment to close the caps on the patient specimens that have completed the inspection work. , the operation of manually opening the cap of the blood collection tube has the following disadvantages: 1. The labor is cumbersome; 2. It takes a long time; 3. The risk of biological safety is high. If there is a rupture of the test tube opening and the operator is scratched, the local negative pressure in the tube is suddenly released during the cap opening process. Blood sample splashes and aerosols are formed, which lead to bacteria and viruses infecting medical staff; in addition, the labor intensity of opening the vacuum blood collection tube and closing the blood collection tube cap after the inspection is completed, which is more likely to cause biological hazards to operators Therefore, it is discarded after opening the cover, and it is almost impossible to close the cover, and it is impossible to do one-to-one matching of patient specimens. Blood samples without a cover can easily cause environmental and biological pollution during refrigerator storage, disposal and transfer.

[0004] In order to overcome the above-mentioned defects, an integrated machine for opening and closing the vacuum blood collection tube came into being; however, for the existing integrated machine for opening and closing the vacuum blood collection tube, the structure of the opening and closing the lid has an unreasonable design and is stable and reliable.
