The utility model content
Given this, the purpose of this utility model is to provide that a kind of required sample that can be used for the piezoelectric type biochip supplies analysis is few, sample sample introduction speed fast, the micro sample of accurate positioning is located sampling device fast.
The utility model adopts and 3-position-3-way flow direction cross-over valve is being set to reduce with realizing its purpose the switching time between air and cleaning fluid cleaning detection pipeline and the sample introduction between suction spindle, air strainer, cleaning fluid bottle three and the peristaltic pump, and further divide at the entrance and exit of detection cell and import liquid position sensor is set in addition and outlet liquid position sensor is realized its purpose, the thermostat that further is provided with semiconductor heating and cooling sheet and temperature sensor again in detection cell is realized its purpose.
Micro sample of the present utility model is located sampling device fast, comprise housing (14) and reach the automatic control circuit board (1) of wherein controlling the sample introduction process, the suction spindle (11), peristaltic pump (5), detection cell (15), the waste liquid bottle (9) that are communicated with are successively arranged, piezoelectric type biochip sensor (7) is arranged in the detection cell, and peristaltic pump the place ahead is communicated with suction spindle, air strainer (2), cleaning fluid bottle (3) respectively through 3-position-3-way flow direction cross-over valve (4).
The entrance and exit of above-mentioned detection cell (15) has import liquid position sensor (6) and outlet liquid position sensor (8) respectively.
Above-mentioned 2, require 1 described micro-test sample to locate sampling device fast according to letter of authorization, it is characterized in that thermostat (10) is arranged in the said detection cell (15), said piezoelectric type biochip sensor (7) places thermostat, thermostat that semiconductor heating and cooling sheet (12) and temperature sensor (13) are arranged.
During the utility model work, under the control of the circuit of automatic control circuit board 1, the direction of flow cross-over valve is respectively successively with the cleaning fluid bottle, air strainer, suction spindle is connected through peristaltic pump and detection pipeline, after pipeline cleans sample is being sucked the detection pipeline fast to detecting under the effect of peristaltic pump, and in of the effect of import liquid position sensor with outlet liquid position sensor, the control fluid sample enters the amount and the residence time of detection cell, thereby realize the quick location sample introduction of sample, thermostat guarantees to detect and carries out under steady temperature, and the sample after the detection enters waste liquid bottle.
The utility model and existing sampling device relatively, this sampling device can realize detecting the automatic cleaning of pipeline, automatically drain the interior cleaning fluid of detection pipeline, the liquor sample of trace sent into fast in the detection cell of piezoelectric type biochip sensor and and carries out thermostatic control the detection cell temperature.Whole testing process is carried out in a closed pipeline, is difficult for making sample contaminated.Under the micro sample situation, if adopt existing constant speed sampling device, the sample introduction excessive velocities of sample, sample is difficult for accurately reaching the detection cell position; If sample introduction speed is slow excessively, then sample introduction need expend the plenty of time.The utility model is respectively arranged with import liquid position sensor and outlet liquid position sensor in the porch and the exit of detection cell, can be according to sample at ducted situation, the rotating speed of control peristaltic pump is realized sample positioning control fast and accurately in real time, and required sample size is less than 0.2ml.Therefore the utlity model has that required sample is few, sample sample introduction speed fast, the advantage of accurate positioning.
The utility model is used for the sample sample introduction of the piezoelectric type biochip supplies analysis in fields such as biology, medical science, environmental health monitoring and surveilliance, food quality inspection; The auto injection that also can be used for the automatic biochemistry analyzer of other Liquid Detection.
Below, the utility model is further described to use embodiment and accompanying drawing thereof again.
