the vacuum blood collection bottle 12 is a disposable negative pressure vacuum glass tube capable of realizing quantitative blood collection, and needs to be matched with a vein blood collection needle for use. The principle is that a blood taking tube test tube with a head cover is pre-pumped into different vacuum degrees, venous blood samples are automatically and quantitatively collected by utilizing negative pressure of the blood taking tube test tube, and one end of a blood taking needle is inserted into a vein of a human body and the other end of the blood taking needle is inserted into a rubber plug of the vacuum blood taking tube. The venous blood of the human body is pumped into the blood sample container through the blood taking needle under the action of negative pressure in the vacuum blood taking tube, and the multi-tube collection can be realized without leakage under one-time venipuncture. The inner cavity of the connecting blood taking needle has small volume, the influence on the blood taking volume is negligible, but the probability of occurrence of countercurrent is relatively small, if the inner cavity of the connecting blood taking needle has large volume, the vacuum degree of a part of blood taking tube can be consumed, so that the collection amount of the connecting blood taking needle is reduced.

Magnet 22, also known as a magnet, refers to an object or material that has a magnetic field around and within itself, and is classified into natural and man-made two types. The artificial magnet is usually made of a metal alloy and has strong magnetism. The magnetic field can be divided into a permanent magnet and a non-permanent magnet, namely a hard magnet and a soft magnet.

The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
