Problems solved by technology

The disadvantage is that the excess part in the blood collection tube is air, and 22% of the composition in the air is oxygen
Various components in the blood to be tested in vacuum blood collection tubes are in a living state. Under normal storage conditions, blood cells will greatly change the proportion of blood components after breathing oxygen and absorbing nutrients, making the test results unrealistic. an unresolved problem

Embodiment Construction

[0012] A method for automatic quantitative strain preservation or blood collection: 1. Inject medium into the blood collection test tube, 1) evacuate the blood collection test tube to a complete vacuum, 2) fill the blood collection test tube with an inert gas, the inert gas being one of neon, argon, xenon, and nitrogen 3), the blood collection test tube is evacuated again to reach the required vacuum degree of 150-600mmHg, and the blood collection test tube is a pure inert gas. 2. For bacteria preservation and blood collection, one end of the blood collection needle is inserted into the venous blood vessel, and then the other end of the blood collection needle is inserted into the blood collection test tube through the plug, and the blood is automatically injected into the blood collection test tube to obtain the required blood collection volume. Strains can be preserved and stored by the same method.

Abstract

The automatic quantitative culture collection and blood sample method includes the following steps: 1. evacuating blood sampling test tube; 2. injecting inert gas into the blood-sampling test tube; and 3. further evacuating blood samping test tube to attain the required vacuum degree 150-600 mm Hg. Its inert gas is one of neon, argon, xenon and nitrogen gas. Said autoamtic quantitative culture collection blood-sampling blood-holding device includes blood-taking needle, blood-sampling test tube and tube plug, two ends of said blood-taking needle are equipped with needle respectively, its middle is hose, and the tube plug is positioned on the tube mouth of blood-sampling test tube, and the medium in the blood-sampling test tube is one of neon, argon, xenon and nitrogen gas.

Description

technical field [0001] The invention relates to a medical automatic quantitative blood collection method and a blood collection container thereof. Background technique [0002] At present, the most advanced automatic quantitative blood collection method for medical use at home and abroad is the blood collection test tube vacuum blood collection method, that is, the blood collection test tube is pumped into a gas (air) with a certain degree of vacuum. The mixture passes through the blood collection needle, and the blood is automatically injected into the blood collection test tube. Automatic quantitative blood collection device, including blood collection needles, blood collection tubes, and tube plugs. There are needles at both ends of the blood collection needle, a rubber tube in the middle, and a tube plug on the mouth of the blood collection tube. 3. The disadvantage is that the extra part in the blood collection tube is air, and 22% of the composition in the air is oxy...
