Abstract

The invention discloses a decapping device for a vacuum blood collection tube. The decapping device comprises a rack, a group of gears, a group of end-surface helical disks, pressure heads, a test tube rack and a decapping power component, wherein the test tube rack is provided with at least one row of vacuum blood collection tube positioning units, the number of each column of vacuum blood collection tube positioning units is the same as that of the gears, a non-return part is formed in each vacuum blood collection tube positioning unit after the vacuum blood collection tube is inserted; the decapping power component is connected with the test tube rack and drives the test tube rack to move up and down. With the adoption of the decapping device, decapping can be realized safely, reliably and quickly through reduction of the decapping force.

Description

technical field

[0001] The invention relates to a device for removing the cap of a vacuum blood collection tube. Background technique

[0002] More and more vacuum blood collection tubes are used in hospitals for blood collection. According to incomplete statistics, in 2013 alone, the number of vacuum blood collection tubes used in my country exceeded 6 billion. Before blood sample analysis, especially in the analysis on the automatic centrifuge, it is required to remove the cap of the vacuum blood collection tube. In the early days, the cap was manually removed. The efficiency of blood testing is obviously unacceptable to hospitals and patients.

[0003] In view of this, there has been a capping device for vacuum blood collection tubes in recent years. The design of the uncapping device must first consider the shape and structure characteristics of the vacuum blood collection tube, such as figure 1 As shown, it is the structural principle of a vacuum blood collection tub...
