[0042] Compared with the present invention after the matching vacuum blood collection tube of the existing common vacuum blood collection needle: table: comparison with the present invention after the matching vacuum blood collection tube of the common vacuum blood collection needle

[0043] 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

[0044] 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 anticoagulant for mo...

Abstract

The invention belongs to the technical field of medical apparatus and instruments, in particular relates to a disposable hard connection hirudin anti-coagulation transverse vacuum blood collection kit. In the kit, a vein blood collection needle is connected with a circular connector, the inner cavity wall of the connector is provided with anticoagulant coat, the other end of the connector is connected with a distributing catheter, one passage pipe the distributing catheter is provided with a vacuum stop valve, the other three passage pipes of the distributing catheter are separately connectedwith a connector, the inner cavity wall of each connector is provided with anticoagulant coat, the other end of each connector is connected with a blood sample bottle-inserting needle, and the blood sample bottle-inserting needle is inserted in a blood sample collection bottle composed of a blood sample collection bottle cap, a rubber stopper and a blood sample collection bottle sleeve. By using the blood collection kit of the invention, 1-3 pipes of blood can be collected simultaneously, continuously and fast, thus increasing the blood collection speed, simplifying the blood collection process and reducing the operation links of medical staff such as nurses and the like when blood is collected in clinic; the error rate is reduced; the workload is lowered; the kit is applicable to massive, fast and centralized blood collection operations in clinic; the packing material is reduced; the medical waste is decreased; and the national health-care cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a disposable hard-connected hirudin anticoagulant horizontal vacuum blood collection set for medical use. 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...
