Description
Technical field
The present invention relates to medical instruments field, more particularly, to a kind of arteria hemostix.
Background technology
Arterial blood gas analysis adjusts the various parameters of mechanical ventilation to clinical guidance oxygen therapy and corrects soda acid and electrolyte mistake
Weighing apparatus etc. has very important significance.Arterial blood sample acquisition method has critically important influence, major influence factors to Results of Blood-gas
When having sampling process and a later stage censorship whether with air insulated, whether blood coagulation etc..
The technical requirements of arterial blood air tube mainly have two aspects：1st, arterial blood touches anti-coagulants after entering syringe
Time is more early better；2nd, arterial blood and air exclusion should be made.
One syringe with syringe needle can have three with the position of trapped air, be in syringe respectively；In needle stand；Syringe needle
It is interior.When piston shifts syringe bottom onto, just can only it be left in two, i.e. needle stand and in syringe needle with the position of trapped air.Syringe needle
Interior space is small, and the air of retention is extremely micro；And space is big in needle stand, the volume of trapped air can be more than 30 cubic millimeters
(calculated above by standard syringe needle stand), this is only the vim and vigour composition influence pole of 0.5-1.0ml arterial blood for blood drawing amount
Greatly.
The arteria hemostix clinically used at present, is external import, its anti-coagulants is placed in pin with spherical or sheet
In cylinder, remaining portions air is also wanted in syringe so as to result in.In addition, exhaust air after blood still can lead to pin from syringe needle
Seat, then lead to syringe from needle stand, cause the pollution of blood sample.Therefore, the performance of current product is compared to arteria hemostix
Technical requirements, have a long way to go, it is impossible to meet the clinical accurate requirement to blood gas analysis.
The content of the invention
In view of the above-mentioned problems, being necessary to provide a kind of arteria hemostix, sky can effectively be completely cut off using the arteria hemostix
Gas, it is ensured that take the quality of blood, and effectively realize the purpose of blood anticoagulant.
To achieve these goals, the technical solution adopted by the present invention is as follows：
A kind of arteria hemostix, including syringe, needle stand, pull bar and piston, the syringe are fixedly connected with the needle stand, institute
The end that piston is fixedly connected on the pull bar is stated, the pull bar and the piston are movably set in the syringe, the pin
Through hole of the seat provided with a connection syringe, in addition to a loop bar, the loop bar are movably set in the piston, the loop bar
Position it is relative with the position of the through hole, and one end that the loop bar is extended in the syringe is fixedly connected with a fixture block, institute
The sectional area for stating fixture block is more than the section of the through hole, so that the fixture block can block the through hole, the fixture block is close to described
The end face of through hole is fixedly connected with sleeve, and described sleeve pipe is adapted to the through hole of the needle stand so that described sleeve pipe be inserted in it is described
Through hole, described sleeve pipe surface offers some holes, and the pull bar inner hollow, the other end of the loop bar extends the drawing
Outside bar.
Further, the material of the syringe is colourless transparent plastic.
Further, solid-state anticoagulation agent is equiped with described sleeve pipe, the solid-state anticoagulation agent is heparin lithium.
Further, the diameter of described hole is less than the sphere diameter of the solid-state anticoagulation agent.
Further, when the fixture block is concordant with the piston, the other end of the loop bar extends outside the pull bar
At least 2.5cm.
Further, the fixture block is circle.
Further, the needle stand is provided with needle stand protective cover.
Further, the needle stand protective cover be one end open one end close plastic cylinder, the plastic cylinder it is interior
Footpath and the external diameter of the needle stand match.
Due to using above-mentioned technical proposal, the invention has the advantages that：
The arteria hemostix that the present invention is provided, loop bar is movably set in piston, and one end that loop bar is extended in syringe
A fixture block is fixedly connected with, the sectional area of fixture block is more than the section of through hole, so that fixture block can block through hole, pull bar inner hollow, set
The other end of bar is extended in pull bar and extended outside pull bar.Staff before blood has been gathered, while pushing drawing rod and
Moved in loop bar syringe, the sleeve pipe being connected with loop bar is injected in needle stand just, so as to drain the air in syringe and needle stand, it is to avoid
Influence of the air to collection blood sample.Staff promotes loop bar toward fortune in syringe before syringe needle is extracted after having gathered blood
Dynamic, so that fixture block blocks the through hole of needle stand, at the same time, sleeve pipe blocks needle stand, and then syringe needle is extracted from patient vessel, is had
Effect, which has completely cut off, to be exhausted after blood air and leads at syringe needle and needle stand in syringe, so as to effectively completely cut off air to the blood of collection
Pollution, it is ensured that the quality of blood sample.
The arteria hemostix that the present invention is provided, sleeve surface offers in some holes, sleeve pipe and is equiped with solid-state anticoagulation agent.
The design of sleeve pipe and solid-state anticoagulation agent, on the one hand can exclude the air in needle stand, on the other hand can make the blood of extraction again
Contacted earliest with anti-coagulants, so as to reach the technical requirements of arterial blood drawing to greatest extent, dirt of the air to blood can be reduced
Dye, can reach the effect of blood anticoagulant again.
In summary, arteria hemostix of the invention, pollution of the whole effectively isolation air to blood sample, improves and faces
Accurate requirement of the bed to blood gas analysis, and the effect of blood anticoagulant is reached simultaneously.
