Disposable soft-connection parallel multi-tube hirudin anticoagulant blood-collecting connector

Abstract

The invention belongs to the technical field of medical instruments, and more particularly relates to a disposable soft-connection parallel multi-tube hirudin anticoagulant blood-collecting connector, which is formed in such a manner that: a venous blood collecting needle is connected with a square connector, the wall of the inner cavity of the connector is provided with an anticoagulant coating, the other end of the connector is connected with a catheter which is provided with a vacuum shutoff valve thereon, the other end of the catheter is connected with another connector, the wall of the inner cavity of the connector is provided with the anticoagulant coating, the other end of the connector is connected with a blood sample bottle needle and a distribution catheter, three channel pipes of the distribution catheter are respectively connected with one connector, the wall of the inner cavity of each of the connectors is provided with the anticoagulant coating, and the other end of the connector is connected with the blood sample bottle needle; the disposable soft-connection parallel multi-tube hirudin anticoagulant blood-collecting connector can simultaneously, continuously and fast collect blood as much as the quantity of 1-3 tubes at a time, which raises blood collecting speed, simplifies blood collecting processes so that nurses and other medical staff can reduce operation procedures during clinical blood drawing, lowers mistake making possibility, lessens workload, is favorable for a large number of fast and centralized clinical blood drawing operations, reduces packaging and medical wastes, and lowers medical insurance expenditure of the nation.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a medical disposable soft connection parallel multi-tube hirudin anticoagulant blood collection connector. Background technique [0002] Due to the unbalanced development of my country's current medical level and the uneven update speed of medical equipment, there have always been obstacles to one-time, rapid and large-scale blood collection operations in clinical practice. The traditional method is that nurses use a soft-connected blood collection needle with a traditional vacuum blood collection tube (the connection between the blood collection needle and the blood collection tube is in series), and a large amount of blood collection (according to the needs of clinical examination) often occurs in clinical practice. The blood collection volume of vacuum blood collection tubes is not enough, and 1 to 2 more blood collection tubes need to be added. At this time, the proce...

AI Technical Summary

Problems solved by technology

The traditional design makes nurses and other medical staff increase the operation links when drawing blood; increases the probability of error; increases the workload; it is not suitable for a large number of fast and concentrated clinical blood drawing operations

[0004] 2. There is no anticoagulant in the traditional soft-connected blood collection needle, and anticoagulant is contained in the vacuum blood collection tube, so after clinical blood drawing, it needs to be inverted and mixed immediately (in order to facilitate the better combination of blood and anticoagulant) 5-8 Second-rate

[0005] 3. Too many packaging materials are not conducive to environmental protection and reducing medical waste

[0006] 4. The price is high, increasing the cost of national medical insurance

Due to the cumbersome extraction steps of natural hirudin, the difficulty of raising leeches, and the lack of sources of leeches, it is difficult to obtain a sufficient amount of pure products, which limits research and clinical applications.
