The pop-up device comprises a pop-up key, a pole column and a framework, wherein the pole column is fixed on a testing instrument shell; the framework is fixed on a testing instrument circuit board; the framework is internally provided with an elastic metal ejector pin group and a guide rail; the guide rail is provided with a slide block; the pole column is sleeved by a rotary drive swing block which is respectively connected with the slide block and the pop-up key.
Description
Technical field
The present invention relates to area of medical devices, particularly bio-sensing pick-up unit field.
Background technology
Biosensor testing plate is a kind of analytical equipment of utilizing biosome inherent function to check biomaterial characteristic.Because biosensor testing plate uses biomaterial as detecting element, it possesses good sensitivity and atopic.Therefore, biosensor testing plate can be used for various fields, for example stability assessment of the process measurement of medical treatment/medicine (clinical chemistry analysis and disposal), biological industry, environment measurement, chemicals etc., and its range of application constantly expands.Particularly, in medical diagnosis field, biosensor testing plate is widely used for analyzing the biological sample including blood.Be classified as enzyme analytic type and immunoassay type according to the kind sensor of detecting element, and be classified as optical biosensor test pieces and electrochemica biological sensor test pieces according to the method for target substance in quantitative test biological sample.
The advantage of electrochemica biological sensor test pieces is only to utilize the signal of infinitesimal sample to amplify, and its miniaturization easily realizes, and measuring-signal can be stablized acquisition, and the combination of easy realization and communication facilities.
The use of biosensor testing plate need to be inserted in supporting with it pick-up unit, and in the time that biosensor testing plate is inserted in pick-up unit, pick-up unit is identified the target substance in insertion the analytic sample of described biosensor testing plate.After analysis completes, biosensor testing plate need be taken out from slot, existing taking-up mode mostly is directly takes out with hand, but, because hand and sample direct contacts its wholesomeness, security aspect exists certain hidden danger, special in the personnel that need to detect multiple samples, directly gets the cross pollution that likely can cause each sample room with hand, affect the accuracy of testing result, and some poisonous dangerous samples also may cause testing staff's infection.
Existing biosensor testing plate ejecting mechanism, needs user to promote biosensor testing plate eject key forward with finger conventionally, is the button segment distance of going ahead, and biosensor testing plate can leave instrument, launches away.The conventional method that test-strips is inserted to tester and taken out test-strips from tester, at for example United States Patent (USP) 5738244, is described in Chinese patent 201180008388.4 to some extent.There are some shortcomings in conventionally test bar ejecting mechanism, first, so push to test bar eject key needs larger power conventionally because need to overcome spring force forward, and eject key stroke is long, some old-aged diabetics point strength a little less than, promote eject key have any problem, use inconvenience; Secondly,, because ejecting mechanism spring needs to reset, also just need some fixed clamp device, therefore complex structures.
Summary of the invention
The object of the invention is to provide a kind of and exempt hand and with detecting the direct touch opportunity of biosensor testing plate of sample, the biosensor testing plate device for ejecting simple in structure, easy to use of avoiding cross pollution between sample, avoiding testing staff to infect.
The present invention is achieved in that biosensor testing plate device for ejecting, it is characterized in that comprising and eject button, be fixed on roofbolt on testing tool housing, be fixed on the framework on testing tool circuit board, elastic metallic thimble group is set in described framework, guide rail is set on framework, on guide rail, is provided with slide block; On described roofbolt, cover has rotatable transmission centering block; Transmission centering block is connected with ejection button with slide block respectively.
Described slide block inner side is provided with push rod, and push rod is less than test pieces thickness apart from circuit board distance.
It is arc that described elastic metallic thimble group is pressed contact, presses contact and circuit board in an acute angle.
When work, it is framework that test pieces is inserted to bio-sensing pick-up unit slot, elastic metallic thimble group generation deformation, accumulation elastic potential energy; When being completed, press ejection button, drive transmission centering block to rotate around roofbolt, transmission centering block promotes slide block and slides onto along the guide rail on framework the position that test pieces ejects, the push rod of slide block inner side is pushed into elastic metallic thimble group by test pieces rear end and presses rear end, contact, and the deformation of elastic metallic thimble group recovers, and discharges elastic potential energy, and being translated into the kinetic energy of test pieces, the kinetic energy producing when pressing ejects test pieces.
In sum, the present invention is furnished with elastic metallic thimble group and movable sliding block, after completing, detection, by slide block, biosensor testing plate rear end is pushed into the bending camber line of elastic metallic thimble group position, then the deformation of elastic metallic thimble group recovers, discharge elastic potential energy, be translated into the kinetic energy of biosensor testing plate, and then biosensor testing plate is ejected, its structure is very simple, operate easily convenient, a kind of hand and direct touch opportunity of biosensor testing plate with detection sample of exempting, avoid cross pollution between sample, that avoids that testing staff infects is simple in structure, biosensor testing plate device for ejecting easy to use.
