Description
Technical field
The utility model belongs to technical field of medical instruments, is specifically related to a kind of chemical illumination immunity analysis instrument reaction cup single needle waste suction liquid device.
Background technology
Full-automatic chemiluminescence immunoassay analysis meter is by detection patients serum thus human body is carried out to the medical laboratory instrument of immunoassay.Quantitative patients serum and horseradish peroxidase (HRP) are joined solid-phase coating to be had in the White-opalescent microwell plate of antibody, antibody specific binding on testing molecule in serum and the bond of horseradish peroxidase and solid phase carrier, the unreacted free composition of separating, washing; Then, add liquid of the luminous end, the free energy utilizing chemical reaction to discharge excites intermediate, gets back to excited state from ground state, and energy discharges with the form of photon; Now, microwell plate is inserted in analyser, by the three-dimensional kinematic train of instrument internal, read the photon number in each hole successively by photon counter, and carry out quantitative test according to the mathematical model that standard items are set up, just can draw detection analysis result.
Wherein after separating, washing, waste liquid after washing need be cleaned out, what traditional analyser adopted is board-like reaction cup, many aspirating needles have been used to the imbibition simultaneously of multiple reaction cup when drawing waste liquid, many aspirating needles connect same negative pressure source of the gas, make the imbibition effect of every root pin different like this, inconsistent to the cleaning effect of waste liquid, cause the last result measured to produce various error.
Utility model content
For solving above technical matters, the utility model provides a kind of chemical illumination immunity analysis instrument reaction cup single needle waste suction liquid device.
Technical scheme is as follows:
A kind of chemical illumination immunity analysis instrument reaction cup single needle waste suction liquid device, its key is: comprise supporting vertical plate, this supporting vertical plate is vertically provided with line slideway, this line slideway is provided with liquid absorbing arm, this liquid absorbing arm is equipped with aspirating needle, and the upper termination negative pressure source of the gas of this aspirating needle, is provided with lead screw motor on the top of described supporting vertical plate, the screw mandrel of this lead screw motor is parallel with described line slideway, and the screw mandrel of this lead screw motor is threaded with described liquid absorbing arm.The remarkable result of this design is, provide a kind of single needle effluent absorption device, lead screw motor drives liquid absorbing arm, drive aspirating needle to decline again, aspirating needle is sent in single reaction cup and draws waste liquid, after absorption waste liquid completes, liquid absorbing arm drives aspirating needle to rise, aspirating needle is extracted out from reaction cup, and outer topworks changes cup, makes next reaction cup aim at aspirating needle; The waste liquid of each reaction cup is drawn by same aspirating needle, ensures that the clean result of each reaction cup is consistent, substantially reduces error.Line slideway can ensure that liquid absorbing arm is steadily elevated, and control liquid absorbing arm lifting by lead screw motor, the even precision of height of liquid absorbing arm is higher, aspirating needle better handling.
Syringe is set with on above-mentioned aspirating needle top, described liquid absorbing arm offers syringe fixed step hole, described syringe cross-under is in described syringe fixed step hole, clearance fit between this syringe and described liquid absorbing arm, described liquid absorbing arm is provided with syringe pressing plate, and described syringe compresses by this syringe pressing plate.The program by syringe by aspirating needle cross-under on liquid absorbing arm, aspirating needle can be protected not to be damaged, ensure that simultaneously assembling and dismounting convenience.
Above-mentioned liquid absorbing arm is vertical with described supporting vertical plate, and one end of this liquid absorbing arm is arranged on described line slideway, and the screw mandrel cross-under of described lead screw motor is at the middle part of described liquid absorbing arm, and described aspirating needle is near the external part of described liquid absorbing arm.Adopt the program, liquid absorbing arm good stability, aspirating needle lifting steadily.
Beneficial effect: the chemical illumination immunity analysis instrument reaction cup single needle waste suction liquid device adopting above technical scheme, the waste liquid of each reaction cup is drawn by same aspirating needle, clean result is even and good, the lifting of aspirating needle is handling good, the clean result of each reaction cup is consistent, substantially reduces error.
