Description
Technical field
The present invention relates to field of medical technology, more particularly to a kind of blood gas analyzer and its vim and vigour biochemical test card.
Background technology
Vim and vigour biochemical test card is widely used in medical industry, and the test card integrated biochemical test electrode, by examination
Calibration solution in agent bag is calibrated, and then test fluid is tested.Vim and vigour biochemical test card typically passes through
Test fluid is introduced by fluid pipeline, and is opened or closed to beat by arranging on-off switch plug in test card main body
Fluid pipeline is closed, in order to liquid leakage is prevented, adhering and sealing film is used for covering passage typically in test card main body
Easily there is the problem that poor attachment causes gas leakage in switch plug, diaphragm seal, and as channel switch plug is prominent
Go out the surface of test card main body, larger cavity need to be reserved in diaphragm seal position of arching upward, and test fluid cannot be complete
This cavity is filled, easily in this cavity, bubble is remained, the bubble easily carries out gas exchanges with test fluid,
Test result is easily affected.
Content of the invention
It is an object of the invention to provide a kind of blood gas analyzer and its vim and vigour biochemical test card, can avoid Lou
Gas problem, and test accuracy is improved, and it is easy to production.
For realizing the purpose of the present invention, adopt the technical scheme that：
A kind of vim and vigour biochemical test card, at least includes press part, test card main body, is arranged at test card main body
On fluid pipeline and test card main body connect and seal the elastic component of fluid pipeline, fluid pipeline and elasticity
The opposite face of part is provided with groove, and Wei Yu groove and press part between, press part is provided with and groove the first elastic component
The pressure head of form fit.
When test card takes out calibration solution, press part is to one side shifting of groove, after pressure head compresses the first elastic component, band
Together to one side shifting of groove, to when fitting with groove, elastic component is pressed on pressure head to movable press head to dynamic elasticity part
And groove between, elastic component is filled on groove by the elastic deformation of itself, closes fluid pipeline；Test
Card by calibration solution complete calibration after, when test solution is taken a sample test, press part to the side shifting away from groove, and
First elastic component is gradually left, until after the external force on elastic component is eliminated, elastic component leans on the elastic deformation of itself
Make elastic component that groove is left, open fluid pipeline, test fluid flows into the test of test card by fluid pipeline
Position.Groove is arranged in fluid pipeline, is integrally formed with fluid pipeline, there is no unnecessary cavity, not residual
Bubble being stayed, while reducing test fluid consumption, improving test accuracy；Break-make need not be set in test card main body
Switch plug and the diaphragm seal for covering channel switch plug, it is to avoid leakage problem, reduce number of parts,
It is easy to production, reduces product fraction defective.
Below technical scheme is further illustrated：
It is further that bottom portion of groove is provided with the jut raised to the first elastic component side.Elastic component is filled
During on groove, jut is bumped in elastic component, makes the obturation effect of fluid pipeline more preferable.
It is further that elastic component includes the first elastic component being covered on groove and is attached at the first bullet
Second elastic component of property part dorsad groove side.When movable press head is extremely fitted with groove, first on elastic component
Elastic component is pressed between pressure head and groove, and the first elastic component is filled on groove by the elastic deformation of itself,
Close fluid pipeline；, after calibration solution completes calibration, when test solution is taken a sample test, press part is to remote for test card
From a side shifting of groove, and elastic component is gradually left, until after the external force on elastic component is eliminated, elastic component
By the second elastic component natural resiliency recover drive the first elastic component leave groove, the second elastic component rise support and
Reset response, while preventing the first elastic component from deforming, it is ensured that the first elastic component is effective after external force elimination
Reset, make the reset effect of the first elastic component more preferable.
It is further that the first elastic membrane is flexible silicon glued membrane, the second elastic component is PET film.Pellosil

Good, its obdurability, tensile strength and shock resistance are strong, and reset deformation effect is good.
It is further that elastic membrane also includes glued membrane, is bonded with glue between test card main body and the first elastic component
Film.The first elastic component is bonded in test card main body by glued membrane, is easy to production assembling.
It is further that groove is ball recess, pressure head is spherical indenter.The surface of ball recess is arc
Face, makes the first elastic component be easier to be filled on groove, makes the obturation effect of fluid pipeline more preferable.
The present invention also provides a kind of blood gas analyzer, including reagent bag, pump and vim and vigour biochemical test card, vim and vigour
Biochemical test is arranged with the bleeding point of the calibration solution mouth that is connected with reagent bag and pump connection, calibration solution mouth and takes out
Gas port is all connected with one end of fluid pipeline.
When taking out calibration solution, fluid pipeline is closed by vim and vigour biochemical test card by press part, and bleeding point is connected with pump
Logical, after pump energising work, make in test card pipeline, to produce negative pressure, reagent job contract makes calibration solution by calibration
Liquid mouth enters the test position of vim and vigour biochemical test card from reagent packet stream；After the completion of calibration, pump works on to be made to determine
Standard liquid detaches the test position of test card, and press part leaves groove, and test fluid flows into survey in the presence of negative pressure
The test position of examination card, test position are tested to test fluid, the vim and vigour with the vim and vigour biochemical test card
Analyzer test is more accurate.
It is further that blood gas analyzer also includes drive ram to the reciprocating driving dress in groove side
Put.Press part motion is driven by driving means, make the operation of blood gas analyzer simpler.
It is further that driving means are motor, pump is vavuum pump.
Compared with prior art, the invention has the advantages that：
