Description
Technical field
The utility model is related to the field of medical instrument technology, specifically a kind of substrate for chemical illumination immunity analysis instrument
Filling and waste liquid draw-out device.
Background technology
Existing chemical illumination immunity analysis instrument, two kinds as disclosed in publication number CN102147406A, CN102419375A
Full-automatic chemiluminescence immunoassay analysis meter carries out waste liquid extraction again after substrate fills, and substrate filling and waste liquid extraction have two
Mutually independent drive system is covered, causes complicated, control difficulty is big, less efficient, and cost is also high.
Invention content
In order to solve the above technical problems, the utility model provides a kind of substrate of the integral type of chemical illumination immunity analysis instrument
The top of filling and waste liquid draw-out device, including interpretation pedestal, the interpretation pedestal is fixed for placing and orienting response cup item
Cup bar groove, the fixed holder in lower section, fixed guide sleeve bearing and stepper motor on the holder, on the motor shaft of the stepper motor
Fixed gear, is slidably matched Z-direction rack with the guide sleeve bearing, and the gear is engaged with the Z-direction rack；The Z-direction rack
Upper gap pass through after the interpretation pedestal fixed substrate to fill fixed plate, fixed filling in the substrate filling fixed plate
Head, two foundation object filler pipes are connected to from top with the filling head；In the substrate filling fixed plate of the filling head side
Also fixed extraction needle, the also fixed capacitive level probe in the substrate filling fixed plate for extracting needle, in the branch
The optoelectronic switch of the fixed detection Z-direction rack position in lower end of frame.Optoelectronic switch can ensure Z-direction movement when substrate filling
Position is accurate.Waste liquid liquid level is detected using capacitive level probe, it is clean to ensure that waste liquid extracts.
Further, the substrate filling fixed plate extends to, the bottom concordant with cup bar groove both ends along Y-direction both ends
Fixed light barrier is distinguished at the Y-direction both ends that object fills fixed plate, is opened up on the interpretation pedestal and holds the light barrier and pass through and therewith
The jack of clearance fit.Light barrier can to read airtight space when substrate filling fixed plate moves downward, and ensure reading effect.
Further, gradually narrow contracting forms tip taper directed downwardly, filling head energy part for the lower end of the filling head
It probes into reaction cup item mouth.Filling head pyramidal structure, when substrate filling fixed plate Z-direction is downward, conehead structure can be probeed into partly instead
It answers in glass item mouth, when ensureing quantitative filling, liquid does not splash.Ensure not cross contamination.
Compared with prior art, the utility model substrate filling and waste liquid extract integral structure, can realize it is complete from
Dynamicization operates, and efficiency improves.Filling head may make two charging lines to collect in substrate filling, not be connected with each other, filling head
Bottom pyramidal so that substrate can be accomplished not splash outward when filling.It is clean that capacitive level probe ensures that waste liquid extracts.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
Referring to attached drawing, a kind of substrate filling of chemical illumination immunity analysis instrument and waste liquid draw-out device, including interpretation pedestal
1, the top of the interpretation pedestal 1 it is fixed for places with the cup bar groove 2 of orienting response cup item, the fixed holder 11 in lower section, it is described
Fixed guide sleeve bearing and stepper motor 12 on holder 11, fixed gear on the motor shaft of the stepper motor 12, with the guide sleeve
Bearing is slidably matched Z-direction rack 7, and the gear is engaged with the Z-direction rack 7；Pass through to the upper gap of the Z-direction rack 7
Fixed substrate fills fixed plate 3 after the interpretation pedestal 1, and the substrate fills fixed filling head 5 in fixed plate 3, two foundation objects
Filler pipe 6 is connected to from top with the filling head 5；Also fixed pumping in the substrate filling fixed plate 3 of 5 side of the filling head
Needle 9 is taken, the also fixed capacitive level probe 10 in the substrate filling fixed plate 3 for extracting needle 9, in the holder 11
Lower end fixed detection 7 position of Z-direction rack optoelectronic switch 8.The substrate filling fixed plate 3 is extended to along Y-direction both ends
Concordant with 2 both ends of cup bar groove, fixed light barrier 4, the interpretation bottom are distinguished in the Y-direction both ends of the substrate filling fixed plate 3
It is opened up on seat 1 and holds the light barrier 4 and pass through and the jack of clearance fit therewith.Gradually narrow contracting is formed for the lower end of the filling head 5
Tip taper directed downwardly, the filling head 5 can be probeed into partly in reaction cup item mouth.
The control system of chemical illumination immunity analysis instrument can control the positive and negative rotation of stepper motor, rotation opportunity and turning collar
Number is moved up and down or is hovered along Z-direction to control substrate filling fixed plate 3, stops when being moved down into setting position, to anti-
It answers and increases substrate in glass item and extract waste liquid, stop when being moved upwards up to setting position after extracting waste liquid, be ready for down
Primary filling and waste liquid extract operation.The substrate fills and the sequence of waste liquid extraction is：Preceding, waste liquid, which extracts, to exist for substrate filling
Afterwards, two functions are at two adjacent reaction cup item mouths, i.e., reaction cup item mouth filled substrate interpretation it is complete after, in next step directly
Waste liquid extracts.
