Blood collecting tube capable of detecting vacuum degree

Abstract

The invention discloses a blood collecting tube capable of detecting vacuum degree. The blood collecting tube comprises a blood collecting tube body, a cork and a plastic cap, and is characterized in that an insertion hole is formed in the top of the plastic cap, an annular concave part is arranged on the side wall, close to the top, inside the plastic cap, an annular seal groove for insertion of an open hole of the blood collecting tube is formed in the cork, the cork body outside the annular seal groove is embedded into the annular concave part, longitudinal grooves extending from the edge to the annular concave part are arranged on the inner wall of the plastic cap, the side wall of the plastic cap is provided with a longitudinal opening, an elastic strip is arranged in the longitudinal opening, and is connected with the side, far away from the top of the plastic cap, of the longitudinal opening, the free end of the elastic strip is connected with a bulge protruding out of the inner surface of the side wall of the plastic cap, an interval is reserved between the bulge and the annular concave part, a spherical concave part rotatably cut off is arranged below the center of the cork, a red flexible membrane is arranged below the cork, and a user can observe the red indication of the flexible membrane through the cork.

Description

technical field [0001] The invention relates to a medical blood collection device, in particular to a blood collection tube capable of detecting vacuum. Background technique [0002] my country is a country with a large population. With the improvement of living standards, people pay more attention to their own health. The medical consumables in disease treatment and preventive physical examination have increased greatly, especially the consumption of blood collection tubes used as the main basis for diagnosis. Most of the blood collection tubes are vacuumed and have medicine attached. After venipuncture, the other end of the puncture needle hose is inserted into the blood collection tube, and the venous blood is drawn into the blood collection tube by the internal negative pressure of the blood collection tube. It has the advantages of fast and safe, and gradually replaces the syringe for blood collection. Since the blood is drawn out by the internal negative pressure of the ...

[0002] my country is a country with a large population. With the improvement of living standards, people pay more attention to their own health. The medical consumables in disease treatment and preventive physical examination have increased greatly, especially the consumption of blood collection tubes used as the main basis for diagnosis. Most of the blood collection tubes are vacuumed and have medicine attached. After venipuncture, the other end of the puncture needle hose is inserted into the blood collection tube, and the venous blood is drawn into the blood collection tube by the internal negative pressure of the blood collection tube. It has the advantages of fast and safe, and gradually replaces the syringe for blood collection. Since the blood is drawn out by the internal negative pressure of the blood collection tube, it is necessary to ensure that the blood collection tube maintains sufficient negative pressure during blood collection, otherwise blood cannot be collected or sufficient blood can not be collected. Due to the influence of environmental factors such as transportation or storage and time, individual blood collection tubes often have no negative pressure or insufficient negative pressure, which affects blood collection efficiency and easily causes conflicts between doctors and patients. Judgment is particularly important, but existing blood collection tubes cannot make judgments intuitively, and this aspect still needs to be improved
