Embodiment Construction

[0021] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0022] The manufacture method of the vacuum blood collection tube of the present invention comprises the following steps:

[0023] Step 1: vacuumize the blood collection test tube;

[0024] Step 2: Add carbon dioxide gas into the blood collection test tube;

[0025] Step 3: vacuumize the blood collection test tube again to reach the required vacuum degree, and seal the blood collection test tube with a rubber stopper, thereby forming a vacuum blood collection tube with carbon dioxide as a protective gas.

[0026] Due to the use of carbon dioxide as the protective gas, the vacuum blood collection tube of the present invention not only avoids the oxidation of the blood sample in the blood collection tube, but also ensures that the carbon dioxide in t...

Abstract

The invention discloses a vacuum blood collection tube and a manufacturing method thereof. The manufacturing method of the vacuum blood collection tube comprises the steps as follows: a blood sampling test tube is vacuumized; carbon dioxide gas is added in the blood sampling test tube; in addition, the blood sampling test tube is vacuumized again so as to achieve needed vacuum degree, and the blood sampling test tube is sealed up by a rubber plug. According to the vacuum blood collection tube and the manufacturing method thereof, carbon dioxide gas mediums are injected in the blood sampling test tube, blood samples in the blood sampling test tube cannot be oxidized, and carbon dioxide in the blood samples cannot be separated out, so that the stability of the blood samples is ensured, and the accuracy of detection results can be improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a medical vacuum blood collection tube and a manufacturing method 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. The vacuum blood collection tube specifically includes the following two methods: (1) directly vacuum the blood collection tube, and add a rubber stopper under the vacuum state , and ensure a certain degree of vacuum; (2), evacuate the blood collection tube, then add an inert gas (one of radon, nitrogen, argon, xenon, neon), and then evacuate, and add in a vacuum state Rubber stopper. In mode (1), blood samples are susceptible to oxidative denaturation due to residual air in vacuum blood collection tubes; in mode (2), blood samples are not easily oxidized due to inert gas remaining in vacuum blood colle...
