Description
Technical field:
The utility model relates to field of medical article technology, and in particular to a kind of blood-taking device.
Background technique:
Clinically the needle of blood taking needle stabs an always security hidden trouble, and the blood taking needle syringe needle used now is too thin,
Outpacking rubber set is substantially to shield, and but there is also very big safety problems, and many medical staff's reflections: syringe needle is too thin,
Heparin tube nozzle is larger, and there are also a small distance, syringe needles can only be inserted in when injecting heparin tube for needle point of the rubber sleeve front end far from the inside
Middle, just in case having inserted inclined a bit, blood taking needle will pierce out from the side of rubber sleeve, extract blood taking needle after a pipe blood is adopted
When just will appear rubber sleeve retraction, syringe needle cannot be retracted into inside rubber sleeve, and rubber sleeve is difficult to pull out from heparin tube, makes
Syringe needle leakage causes next blood drawing inconvenient, and blood is caused to leak outside, and be easy to cause medical staff oneself by blood dirt
Dye or needle are stabbed, of no avail by connecting tube reflexed；In nursing staff, some mismatch or uncomfortable is encountered
In the case of patient's emergent management of while being all passive position (for example gout patients are unable to limbs to stretch), medical staff oneself is by blood
Liquid pollution or needle stab and are easier to have occurred.
Have a kind of needle holder on the market now, its function first is that with blood taking needle cooperate, be connected through a screw thread, make to take a blood sample
Needle is fixed with needle holder；Two vacuum blood collection tubes of function are embedded in needle holder open end, are clearance fit, with the blood sampling connected in advance
It is needled into test tube rubber plug；This kind of needle holder, when switching each patient, is required due to being to be connected through a screw thread with blood taking needle
The needle holder being previously connected on blood taking needle is screwed off and is screwed on the blood taking needle that next patient uses again, is thus expended very much
Time, while also increasing the working strength of medical staff, extending the waiting time of patient；Simultaneously because vacuum blood collection tube is embedding
Entering needle holder open end, is clearance fit, medical staff, inevitably can be embedding partially by vacuum blood collection tube when the task of blood sampling is bigger,
