Problems solved by technology

However, for some special groups that are anemic or difficult to collect venous blood, the use of vacuum blood collection tubes for blood collection cannot achieve good results, and blood hemolysis is often caused by excessive residual negative pressure in the tube, which affects the detection progress
For infants and young children, due to the particularity of blood vessels and blood cells, it is difficult to ensure sufficient venous blood collection, and excessive blood collection may even easily cause iatrogenic anemia, so there is still a need for peripheral blood collection in clinical practice
[0005] It is worth mentioning that common micro-volume distal tubes are difficult to meet the requirements of existing automatic labeling and on-machine instruments, and often require a lot of manual operations, which affects the efficiency of blood collection, and repeated opening of the cap is likely to cause biological contamination. However, the currently used Vacuum blood collection tubes cannot meet the requirements of venous and peripheral blood collection at the same time

Embodiment 1

[0028] like figure 1 with figure 2 As shown, a blood collection apparatus includes a blood collection tube 2 and a seal 8; the seal 8 is mounted on the blood collection tube 2; the blood collection tube 2 is divided into the blood collection and collecting portions, and the blood collection is provided. Cancer port 12, the blemilifier port 12 is provided with an outer edge 11 and a drainage slope 13, guiding liquid into the collection portion; when blood collection, the tube puncture of the blood collection needle is punctured on the seal 8, and the blood passes through the puncture needle Introduced within the collection department; the bottom of the collecting portion is closed, which can be used for intravenous blood collection or intravenous blood collection, and the blood sample after blood samples after blood collection.

[0029] The outer edge 11 of the blood collection portion performs a flexible treatment of a chamfer or fillet, the angle of the chamfer or rounded angle o...

Embodiment 2

[0042] like Figure 1 to 3 As shown, a blood collection apparatus includes a blood collection tube 2 and a seal 8; the seal 8 is mounted on the blood collection tube 2; the blood collection tube 2 is divided into the blood collection and collecting portions, and the blood collection is provided. Cancer tube 12, the blemilifier port 12 is provided with an outer edge 11 and a drainage slope 13 guide liquid into the collection portion; when blood collection, the test tube of the blood collection needle is punctured on the seal 8, and the blood is introduced by puncture needle In the collection department; the bottom of the collecting portion is closed, which can be used for intravenous blood collection or intravenous blood collection, blood samples after blood samples after blood collection.

[0043] The outer edge 11 of the blood collection portion performs a flexible treatment of a chamfer or rounded corner, the angle of the chamfer or rounded angle of 30 ° to 60 °, the angle length...

Embodiment 3

[0056] Example 3: Seals for use in the present invention

[0057] The seal can be used in an integrated blood collection apparatus according to Embodiment 1 or a split blood collection device according to the second embodiment.

[0058] like Figure 4 As shown, the seal 8 includes a hard hat 1 and an elastic member 24, the elastic member 24 is disposed inside the heat casing 1, and the inside of the seal 8 is an embedded elastic member 24, which is safe. A through hole 23 is provided at one end of the cap 1.

[0059] The elastic member 24 includes a plug 22 and an elastic glue plug that seals the sealing region 16 disposed in the blood collection tube 2, and is contracted and the blood collection tube 2 is contracted by the sealing region 16 disposed in the blood collection tube 2. The test tube is closely fitted, and the negative pressure is stable in the tube, preventing blood samples from splashing, reducing the interference of exogenous substance intrusion; the elastic member 2...

Abstract

The invention discloses a multifunctional blood collection device suitable for collecting trace blood samples, which comprises a blood collection tube and a seal; the seal is installed on the blood collection tube, and the vacuum blood collection by venipuncture is realized through the seal; the blood collection tube is divided into a blood collection part and a collection part , the blood collection part is provided with a guide tube port, and the guide tube port is provided with an outer edge and a drainage slope to guide the liquid into the collection part for collection; the bottom of the collection part is closed. The present invention is used to collect venous blood when the seal is connected to the blood collection tube, and realizes peripheral blood collection when the blood collection part is separated from the seal. Matched with the upper machine instrument, it realizes multi-functional blood collection and standardized processing.

Description

Technical field [0001] The present invention relates to the field of blood collection techniques, and in particular, a multi-functional blood collection device suitable for trace blood sample collected. Background technique [0002] In recent years, with the development of medical technology, the application of vacuum blood collection test tubes in clinical blood test is also more extensive. According to the clinical needs, the vacuum blood collection tube can be divided into many types, such as ethylenediamine tetracetate (EDTA) anticoagulant, heparin tube, blood coagulation, and laminating tube, etc.. In implementing the present invention, the inventors have found that the prior art is at least as follows: [0003] During clinical diagnosis and treatment, the clinical laboratory usually needs to extract a large number of blood from the patient, but there is still more blood collection disorders in practice, such as small samples, hemolysis , Blood splash, excessive residual neg...
