Description
Technical field:
The present invention relates to the technical field of Medical Equipment, it is specifically related to a kind of blood collection dress of medical test
Put.
Background technology:
Medical test is a subject carrying out medical diagnosiss with modern physicses chemical method and means, and it is mainly studied
How to be clinical diagnosises, offer foundation is provided by laboratory technique, medical instruments and equipment.By systematically learning, Wo Menneng
Learn how by medical test come the blood group of surveyor, whether anemia and liver function are normal etc. to determine a people.Blood
Collection, chemical examination are conventional medical test modes, usually need to carry out blood collection, existing blood collection in blood sugar test
The acquisition method of device typically punctures finger by blood taking needle, but in some special cases, blood sampling object generally requires with strength
Extruding finger, to be easy to extract blood out, and therefore existing blood collector is using trouble, inefficiency.
Content of the invention:
The purpose of the present invention aims to solve the problem that the problem that prior art exists, and provides a kind of blood sampling object just need not extrude finger
Can complete to take a blood sample, using the blood collection device of the medical test of simple and efficiency high.
The present invention relates to a kind of blood collection device of medical test, including sleeve pipe, it is vertical to be provided with described sleeve pipe
Collection tube, the upper end of described collection tube is fixedly connected with Capsule, lower end forms sucker, and the outer side edges of described sucker are fixed on set
On the lower end inside wall of pipe, sucker forms some pin holes, in the sleeve pipe of collection tube surrounding, be provided with some and described pin hole one
One corresponding vertical pricker bar, the bottom of described pricker bar forms needle tip, and described needle tip is located at the top of sucker, thorn
The upper end of shank forms movable block, and described movable block forms tilting arc, some movements on some pricker bars
The arc of block is fixedly connected and is combined into laminate under a taper, and under described taper, laminate covers on the Capsule of collection tube upper end,
Vertical tooth-strip part is formed on the side wall of one of movable block, described tooth-strip part is engaged with driving gear, the side wall of sleeve pipe
On form inserting groove, be hinged with rotating shaft in described inserting groove, the medial wall of inserting groove form hinged groove, described rotating shaft
One end is plugged in described hinged groove, and rotating shaft upper sleeve has reduction torsion spring, and one end of described reduction torsion spring is fixed in rotating shaft, separately
