Problems solved by technology

The volume of the inner cavity connected to the blood collection needle is very small, and the influence on the blood collection volume can be ignored, but the probability of backflow is relatively small. If the inner cavity volume is large, it will consume part of the vacuum degree of the blood collection tube, thereby reducing its collection volume.
[0003] When the traditional vacuum blood collection tube is used, the airtight performance is insufficient, which makes it easy to leak after the blood collection needle is inserted.

Embodiment Construction

[0020] see Figure 1-4 , the immunological blood test tube of this embodiment includes a test tube body 1, and a tube cap 2 that is screwed and fixed at the upper end of the test tube body 1, and a sealing plug 3 is mounted on the inside of the tube cap 2, and the lower end of the sealing plug 3 Inserted into the inside of the inspection tube body 1, an eight-layer sealing plate 4 is arranged at the middle position of the sealing plug 3, and a seven-layer separation cavity 6 is arranged between the eight-layer sealing plates 4, and an inserting plug is arranged at the center of the sealing plate 4. The hole 5 is used to check that a sealing assembly is still arranged between the tube body 1 and the cap 2 .

[0021] In this embodiment, the sealing plug 3 is clamped and installed inside the cap 2. At the same time, the lower end of the sealing plug 3 is inserted into the inside of the inspection tube body 1, so that the inspection tube body 1 is sealed by the sealing plug 3. At ...

Abstract

The invention discloses a blood test tube for immunology, which comprises a test tube body (1) and a tube cap (2), and is characterized in that a sealing plug (3) is clamped and mounted on the tube cap (2), the lower end of the sealing plug (3) is inserted into the test tube body (1), a sealing component is arranged between the test tube body (1) and the tube cap (2), and a label clamping plate (14) is fixed on the outer surface of the test tube body (1). The blood test tube for immunology according to the present invention has outstanding sealing performance.

Description

technical field [0001] The present invention relates to a medical device, in particular to a blood test tube for immunology. Background technique [0002] Blood test tubes are also called vacuum blood collection tubes. The principle of vacuum blood collection tubes is to pre-pump the blood collection tubes with caps into different vacuum degrees, and use the negative pressure to automatically and quantitatively collect venous blood samples. One end of the blood collection needle is inserted into the human vein and the other One end is inserted into the rubber stopper of the vacuum blood collection tube. Human venous blood is inside the vacuum blood collection tube, and under the action of negative pressure, it is drawn into the blood sample container through the blood collection needle. Under one venipuncture, multiple tubes can be collected without leakage. The volume of the inner cavity connected to the blood collection needle is small, and the impact on the blood collect...
