Problems solved by technology

[0002] For the test of disposable venous blood sample collection containers (hereinafter referred to as blood collection tubes), there were no standards and equipment for testing common blood collection tubes in plateau areas, so it was impossible to test the blood collection volume of blood collection tubes
Especially in plateau areas, the air pressure is generally low, and the change is also great within a day, the detection accuracy is low, and it is difficult

Abstract

Provided is a tester capable of simulating any atmospheric pressure environment of a container for venous blood specimen collection. The tester comprises a container, a first supporting frame, a second supporting frame and a third supporting frame, the upper portion of the inner side of the container is provided with a tray, the inner side of the tray is provided with an atmospheric-pressure gauge, one side of the first supporting frame is provided with the second supporting frame, and the top portion of the first supporting frame is provided with an injector. The tester capable of simulatingany atmospheric pressure environment of the container for venous blood specimen collection has the advantages that the atmospheric-pressure gauge is arranged in the container, pressure in the container reaches to a set value before testing by increasing pressure with air inflation or decreasing pressure with air exhaust to adjust the pressure in the container to a proper value, so that the fillingcapacity experiment on a blood-collecting vessel does not need a very high liquid level.

Description

technical field [0001] The invention relates to a test device, more precisely a tester for a venous blood sample collection container capable of simulating any atmospheric pressure environment. Background technique [0002] For the test of disposable venous blood sample collection containers (hereinafter referred to as blood collection tubes), there were no standards and equipment for testing common blood collection tubes in plateau areas, so it was impossible to test the blood collection volume of blood collection tubes. Especially in plateau areas, the air pressure is generally low, and it changes greatly within a day, so the detection accuracy is low and difficult. For example, if you are in a plateau low pressure area, you need the liquid level to reach 2 meters higher, which is impossible for the laboratory. Contents of the invention [0003] The object of the present invention is to provide a venous blood sample collection container tester capable of simulating any ...
