Abstract
The utility model relates to a disposable vacuum blood taking needle assembly, belonging to the medical instrument. A puncture needle is fixedly connected with a puncture needle handle, the puncture needle handle is provided with a fixing single wing, one end of a connecting pipe is sleeved with a puncture needle handle, the other end of the connecting pipe is fixedly connected with a connecting pipe sleeve head, the connecting pipe sleeve head is sleeved with the blood taking needle handle, the blood taking needle handle is fixedly connected with the blood taking needle, the blood taking needle protection rubber sleeve is sleeved with the blood needle handle, the blood taking needle cap is sleeved with the blood taking needle handle, the puncture needle cap is sleeved with the puncture needle; the length of the connecting pipe is 8-10 cm. The utility model has advantages that the structure is novel, the stability is good when adopting the rigid single wing needle handle to puncture, and the needlepoint can be adjusted after puncturing, the connecting pipe length is medium, the negative pressure through the blood taking test tube is enough after puncturing, thereby ensuring the blood taking amount to enable the blood test to be accurate.
Description
Technical field
This utility model belongs to medical apparatus and instruments, refers in particular to a kind of vacuum blood taking needle.
Background technology
Vacuum blood taking needle divides two kinds at present: 1. disposable use vacuum blood taking needle: be made of two-way puncture needle.Shortcoming: limited by puncture angle during the big and puncture of syringe needle model, big to child's venous blood collection difficulty, easily the child is damaged, increase painful; 2. disposable butterfly double-vane needle handle vacuum blood taking needle: connect the connection tube and the unidirectional puncture needle that are about 27cm by the puncture needle of being with the butterfly needle handle and constitute.Shortcoming: the butterfly needle handle is softer, poor stability during puncture, and can not carry out needle point after the puncture and regulate, connection tube length is long, and the blood sampling volume deficiency is easily caused by the negative pressure deficiency of blood sampling test tube in the puncture back, influences the accuracy of blood test.
Summary of the invention
This utility model provides a kind of disposable use vacuum blood collection needle assembly, to solve easily the child being damaged that present vacuum blood taking needle exists, poor stability, negative pressure deficiency easily cause the blood sampling volume deficiency when increasing misery, puncture, influence the problem of the accuracy of blood test.The technical scheme that this utility model is taked is: puncture needle is fixedlyed connected with the puncture needle handle, this puncture needle handle has fixedly single-blade, connection tube one end and puncture needle sleeve connect, the other end is fixedlyed connected with connection tube is pullover, pullover and the blood taking needle needle handle socket of this connection tube, this blood taking needle needle handle is fixedlyed connected with blood taking needle, blood taking needle protection gum cover and the socket of blood taking needle needle handle, blood taking needle pin medicated cap and the socket of blood taking needle needle handle, puncture needle pin medicated cap and puncture needle sleeve connect; This connection tube length is 8～10 centimetres.
The utility model has the advantages that novel structure, good stability when using hard single-blade needle handle puncture, and can carry out needle point after the puncture and regulate, the connection tube moderate length, the puncture back has guaranteed blood sampling volume by the negative pressure foot of blood sampling test tube, makes blood test accurate.
