Abstract
The utility model relates to an automatic liquid adding device used in a medical rapid detection colloidal gold immunochromatographic assay dry-type digital reader. The automatic liquid adding device comprises a pressure pump, a pressure sensor, at least two liquid bottles and electromagnetic valves. One end of the pressure pump sucks the residual liquid on the bottom plate of the digital reader, and the other end thereof is connected with the input end of each liquid bottle; a pressure sensor is arranged at the joint of the gas input ends of every two liquid bottles; and the liquid input ends of the liquid bottles are connected with the respective electromagnetic valves. The automatic liquid adding device provided by the utility model can automatically add reactant liquid in a rapid and accurate way; and an individual test can be completed within about 45s, which is only 1/3 of the time cost in one test using the instrument in the prior art.
Description
Technical field
The utility model relates to a kind of liquid-adding device, particularly relates to a kind of automatic liquid feeder that is used for medical science fast detecting colloidal gold method dry type readout instrument.
Background technology
Contain health whether important information in the human body fluid, comprise the existence of height, specific protein concentration change, pathogen and corresponding antibodies thereof of various hormone-contents and what etc., these project major parts to be measured can be detected with colloid gold immune infiltration technology (gold marking spot method), testing result is that the observing response plate has or not punctation to present, and the depth of punctation is directly proportional with the concentration of measured object.
At present, existing a large amount of professional readout instrument can read the concentration of measured object, but in the past before detecting enforcement, require gold mark liquid, cleansing solution, sample etc. all must to be added on the kit, need to read by surveying by instrument again behind the sufficient reacting on operator's naked-eye observation kit earlier by manual operations.Because be to adopt manual operations, there is individual difference in each operator, causes the addition of liquid uncontrollable, causes reading error, and the generation that liquid is obscured because human error induces reaction sometimes.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of automatic liquid feeder that is used for medical science fast detecting colloidal gold method dry type readout instrument, can add reactant liquor automatically.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of automatic liquid feeder that is used for medical science fast detecting colloidal gold method dry type readout instrument is provided, comprise forcing pump, pressure transducer, at least two liquid bottles and solenoid valve, described forcing pump one end extracts the raffinate that gold is marked the readout instrument chassis by the vacuum pressure difference, and the other end links to each other with the gas input end of each liquid bottles; The junction of the gas input end of described each liquid bottles is provided with pressure transducer; The liquid output terminal of described liquid bottles links to each other with solenoid valve separately.
Described solenoid valve is provided with liquid flow sensor.
Described automatic liquid feeder also comprises the intelligent verifying attachment that is used for the tracer liquid rate of percolation, and described intelligent verifying attachment links to each other with described solenoid valve.
Described forcing pump is a twin pump.
Be provided with retaining valve between the gas input end of described forcing pump and liquid bottles.
Beneficial effect
Owing to adopted above-mentioned technical scheme, the utility model compared with prior art, have following advantage and good effect: the utility model pressurizes to liquid bottles by forcing pump, and by solenoid valve as the liquid feeding switch, the automatic interpolation of realization response liquid.Process quick and precisely, when carrying out single part the detection, omnidistance 45 seconds that were about consuming time, only be in the past instrument do one-time detection consuming time 1/3rd, and precision, the repeatability of monitoring instrument all were significantly improved more in the past.Add the addition that liquid flow sensor is accurately controlled each reaction liquid at the reactant liquor output terminal, need not worry the error that user's main body difference causes again.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1, a kind of automatic liquid feeder that is used for medical science fast detecting colloidal gold method dry type readout instrument comprises forcing pump 1, pressure transducer 3, three liquid bottles 5 and solenoid valves 4.Described forcing pump 1 adopts twin pump, the one end extracts the raffinate on gold mark readout instrument chassis by the vacuum pressure difference, the other end links to each other with the gas input end of each liquid bottles 5 in order to drive liquid bottles 5, this forcing pump 1 can provide 500mbar pressure, and wherein every 100mbar pressure can produce the flow of 660ml/min.The junction of the gas input end of described three liquid bottles 5 is provided with pressure transducer 3, at any time the air pressure in the monitoring liquid bottle 5.The liquid output terminal of described liquid bottles 5 links to each other with solenoid valve 4 separately, and this solenoid valve 4 that is to say as the switch of liquid feeding, the break-make of the on-off control valve door of power supply, power supply adopts pulse control, wherein the width may command valve of conducting pulse time of opening, promptly controls liquid volume added.Described solenoid valve 4 is provided with liquid flow sensor, can accurately control the addition of each liquid.Be provided with retaining valve 2 between the gas input end of described forcing pump 1 and liquid bottles 5, prevent that the liquid in the liquid bottles 5 from flowing backwards.
The utility model also is provided with an intelligent verifying attachment 6 that is used for the tracer liquid rate of percolation, this intelligence verifying attachment can be used for also judging whether the test item that liquid feeding project and user select is consistent in actions menu, the solenoid valve 4 of liquid bottles 5 output terminals of liquid feeding project correspondence can't be opened when inconsistent, and the people is the error of obscuring reactant liquor that causes when therefore having stopped to be similar to manual operations.
Be used for can using multichannel the utility model in the medical science fast detecting colloidal gold method dry type readout instrument, dismantle easyly, be easy to preserve, clean, each road liquid-adding device can be provided with corresponding to a test item according to actual needs by the instrument internal program.When needs switched to another kind of project, the operator can change the liquid bottles in the liquid-adding device easily, and the corresponding program of selecting to set gets final product, if there is temporary transient unwanted liquid to preserve according to operation instruction.
