Embodiment 1

[0029] Embodiment 1 of the disposable hard-connected parallel multi-tube hirudin anticoagulant blood collection connector of the present invention will be described in detail below in conjunction with the accompanying drawings. figure 1 It is the front view of the disposable hard-connected parallel multi-tube hirudin anticoagulant blood collection connector of the present invention. Such as figure 1 As shown, the disposable hard-connected parallel multi-tube hirudin anticoagulant blood collection connector of the present invention is characterized in that the circular connector 3 is connected by the venous blood collection needle 2, and the inner cavity wall of the connector 3 is provided with an anticoagulant coating 1. The other end of the device 3 is connected to the distribution conduit 4, and a vacuum valve 5 is arranged on one access pipe of the distribution conduit 4, and a connector 3 is respectively connected to the other three access pipes of the distribution conduit...

Embodiment 2

[0039] After the existing common vacuum blood collection needle is matched with the vacuum blood collection tube, it is compared with the present invention:

[0040] Table: Comparison with the present invention after a common vacuum blood collection needle is matched with a vacuum blood collection tube

[0041] Ordinary blood collection needles combined with ordinary blood collection tubes required blood drawing time and blood drawing

quantity

Required blood drawing time and blood drawing after the improvement of the present invention

quantity

5-7 seconds blood volume 5ml

Blood collection volume 15ml in 6-8 seconds

[0042] The amount of hirudin added to the anticoagulant vacuum blood collection needle is: 0.01 mg to 10 mg per needle. For example: at present, the amount of hirudin in the blood collection needle is 1 mg, which can make 5 ml of blood anticoagulant for more than 7 days; the amount of 2 mg of hirudin can make 10 ml of blood...

Abstract

The invention belongs to the technical field of medical instruments, and more particularly relates to a disposable hard-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 distribution catheter, one channel of the distribution catheter is provided with a vacuum shutoff valve and three other channels of the distribution catheter are respectively connected with one connector, the wall of the inner cavity of the connector is provided with the anticoagulant coating, and the other end of the connector is connected with a blood sample bottle needle; the disposable hard-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 hard-connected 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 has always been a one-time fast and a large number of blood collection obstacles in clinical practice. The traditional method is that nurses use a hard-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 examinations) 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 process of blo...
