Automatic puncture and analog sampling device for vacuum blood collection tube

Abstract

The invention relates to the technical field of medical instruments, and particularly relates to an automatic puncture and analog sampling device for a vacuum blood collection tube. The device comprises a master control plate, an upper sliding mechanism, a lower sliding mechanism, a sampling needle clamp, a sampling needle, a blood collection tube holder, an installation plate, a hose and a wide-mouth bottle. The upper sliding mechanism and the lower sliding mechanism are arranged perpendicular to each other. The upper sliding mechanism comprises a first motor, a first lead screw, a first sliding block, a first sliding rail and a first proximity sensor. The lower sliding mechanism comprises a second motor, a second lead screw, a second sliding block, a second sliding rail and a second proximity sensor. The first proximity sensor, the second proximity sensor, the first motor and the second motor are all connected with the master control plate. According to the technical scheme of the invention, the vacuum blood collection tube can automatically realize the puncture and the analog sampling in a closed environment. Therefore, the device lays a foundation for the invention of air pressure automatic analog equipment used for detecting the negative-pressure capacity of a vacuum blood collection tube.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an automatic puncture and analog sampling device for a vacuum blood collection tube. Background technique [0002] At present, vacuum blood collection tubes have been widely used in medical and inspection institutions at all levels. Vacuum blood collection tubes with the same nominal capacity are used in different regions. Due to factors such as differences in altitude and climate, the performance of ambient air pressure is different, which will lead to differences in the amount of blood collected. Therefore, when producing vacuum blood collection tubes, manufacturers need to preset the degree of negative pressure according to the user's local atmospheric pressure, so that the product can adapt to the quantitative blood collection under the ambient air pressure conditions of the place of use. However, there is currently no equipment or device on the market that simulat...

Problems solved by technology

However, there is currently no equipment or device on the market that simulates different air pressure environments to display the blood collection volume of vacuum blood collection tubes. Manufacturers or government quality supervision agencies can only use calculation methods to make nominal names for the blood collection volumes of vacuum blood collection tubes under different air pressure environments. Volume check, with error due to methodological limitations
