Technical Field
The invention relates to the technical field of medical equipment, in particular to a vacuum blood sampling device with a leakage-proof function.
Background
Currently, in clinical medicine, vacuum blood collection test tubes are widely applied to blood analysis, and clinical diagnosis bases are provided for clinicians. The main action principle of the blood sampling device is that vacuum is preset in a test tube to form negative pressure, and the purpose of extracting a blood sample is achieved by utilizing the blood pressure of a human body and the pressure difference in the tube.
Most of blood collection tubes on the market at present mainly comprise a tube body, a sealing rubber plug and a protective cap, and test tubes after blood collection can be directly sampled and detected by a full-automatic biochemical analyzer.
As is well known, in order to facilitate the collection of the collected blood sample for testing, the connection between the protective cap and the tube body is not fixed, and the tube body is in a negative pressure state in normal use, so that the protective cap is firmly connected to the tube opening of the tube body.
However, in practice, there are special patients who require blood collection by means of a syringe, since the negative pressure in the vacuum tube is insufficient for blood collection, and then transfer the blood to the uncapped vacuum tube, followed by capping. After opening the vacuum tube cover, the original negative pressure in the vacuum blood collection tube will disappear. After the blood is injected into the vacuum tube, the pressure in the vacuum tube is slightly greater than the atmospheric pressure because the cover is plugged. At this time, the vacuum blood collection tube cover is separated after being slightly stressed, so that blood is splashed out, environment pollution and other blood samples are caused, and working errors are easily caused.
