Description
Technical field
The present invention relates to a kind of hospital laboratory blood sampling apparatus, more particularly to a kind of automatic immediate vacuum blood collection equipment.
Background technology
Venous blood collection is technical operation relatively common in clinical nursing activity, and the past adopts blood collection needle side always
Method, both wasted time and energy, blood sample easily pollution, and haemocyte can be by the standard of destroying infection assay again during metaideophone
True property.In the 1930s, U.S. company BD has invented vacuum blood drawing technique.Present developed country generally uses vacuum blood collection system
System, so that Vacuum tube blood collection is used widely in clinical vein puncture.It is the change of a Puncture, more
Many deficiencies of traditional disposable syringe blood sampling are mended.Time can be greatlyd save using vacuum blood collection method, avoid blood sample
This pollution, ensure that the accurate of blood sampling volume.But it is not a very perfect technology yet, still have it is many it is congenital not
Some problems in foot and operation need to solve.Particular problem is as follows：(1) haemolysis due in vacuum tube negative pressure it is larger, adopt
Blood is initial, and blood inflow ttom of pipe speed is fast, and red blood cell, which mutually hits, can cause to rupture, and foam, which increases, causes haemolysis.(2) residual be present
For negative pressure because ordinary vacuum tube is using extensively, setting negative pressure is larger, if collect specimen amount and the pressure difference value of setting in test tube
It is larger, larger negative pressure still can be remained in previous test tube when changing pipe, causes to dissolve gas overflowing in blood, causes red
Cell expansion ruptures, and causes haemolysis.In addition, the negative pressure of remaining can also reduce the speed of blood clotting, slow down clot contraction.
(3) leakage blood causes blood to pollute, and bidirectional blood taking needle blood sampling pipe end latex sheath loosens or syringe needle pierces out latex sheath, causes two-way
Blood taking needle is poorly sealed.During venipuncture, pipe close puncture needle end or interface of the blood along bidirectional blood taking needle are spilt.Rubber stopper is thick
Degree is big, Ci Sai and to pull out pin laborious, syringe needle bonding loosely when syringe needle can be caused to deviate from.(4) it can not judge that whether successful puncture is double
Judge that whether successful puncture is more difficult when puncturing without blood back to syringe needle, can only be with operator's sensation, experience or connection vacuum tube
After have blood flow into can judge puncture whether succeed.But if connecting vacuum tube when puncturing, puncture failure causes vacuum tube to be born
Pressure is reduced to be caused to waste again.Traditional blood collection needle after syringe needle intravasation, can by pumpback come determine whether puncture into
Work(, and vacuum blood collection tube can not solve by pumpback method, so in distress when being taken a blood sample for full not good enough and minute blood vessel
Degree.(5) can not be loosened by being sealed during manufacturer production, during use without negative pressure or the inadequate vacuum blood collection tube of negative pressure in test tube lid to prevent
Vacuum expendable pattern.But whetheing there is vacuum can not with the naked eye identify, be also impossible to before clinical practice in first detection pipe vacuum state with
Useless pipe is excluded, therefore there is a situation where to puncture successfully but adopts not bleeding after piercing heparin tube or blood volume is inadequate.(6) blood sampling volume is not
Can autonomous control blood preparation it is excessive or very few blood clotting in anticoagulant tube will occur, promote the phenomenon hair that blood does not coagulate in solidifying pipe
It is raw.A small number of heparin tubes have quality problems unavoidably causes negative pressure in heparin tube insufficient or too high.(7) test tube manufacturing cost height in order to
Negative pressure is kept for a long time, it is necessary to the good chlorinated butyl plug of use quality and PET test tubes and medical grade teat glass, it is impossible to use
The test tube of soft material, causes cost to improve, the financial burden of making patients, is not suitable for wanting for the overall situation that current medical is reformed
Ask.(8) there is the shortcomings that fatal human factor：Vacuum blood collection tube is not arranged in process of production or after being sold to hospital
Except some people deliberately destroy, the negative pressure in vacuum tube is bled off, manufacturing contingences, causes complaint of the user to producer's quality problems.Mesh
Preceding technology there is no the vacuum state in method test tubes, and problems can not solve.
In order to overcome above mentioned problem, the present inventor once applied《Airtight negative-pressure automatic hemostix device》The patent No.
99214075.7《Totally-enclosed negative pressure hemostix》The patent No. 95245460《Airtight negative-pressure automatic hemostix device》Number of patent application
98112817 [publication numbers]：1225809.《Immediately a kind of double needle thorn plug system of vacuum blood collection equipment》Number of patent application
201210490834.6 its advantages of remaining vacuum blood collector, its shortcoming is overcome, but need to solve there are still problem：
1st, installation test tube by hand is needed, holding test tubes are also wanted after blood sampling, it is still inconvenient for the big hospital operation of blood sampling volume, it is cumbersome.
The content of the invention
