Abstract
The utility model relates to an optical electromechanical integral automatic measuring analyzer for microbes, which is characterized in that the automatic measuring analyzer for microbes is composed of a CCD scanning device and a universal microcomputer which are connected together. Signals acquired by the CCD scanning device are sampled timely, calculated, analyzed and displayed by the microcomputer. The automatic measuring analyzer realizes the automatic measurement, analysis and calculation of microbes, and achieves the high efficiency, high precision and automatization of microbe detection.
Description
The utility model is the automatic measurement and analysis instrument of a kind of microorganism, is used for microorganism detection titer of antibodies Measurement and analysis, drug sensitive test, enumeration and blood concentration analysis etc., belongs to the measuring apparatus technical field.
Current, in microorganism detection, generally adopt manual measurement, calculating and analysis both at home and abroad, use in the hands such as slide calliper rule, magnifying glass, counter and operate.Schedule of operation is numerous and diverse, and accuracy is lower, and in the vessel microbiological culture media the smell is awful, influence operator ' s health.
For this reason, the purpose of this utility model is to release a kind of microorganism detection device that the CCD scanning techniques is combined with micro-computer technology, realization is to automatic measurement, analysis and the calculating of microorganism, reach high-level efficiency, pinpoint accuracy and the automatization of microorganism detection, improve operator's Working environment simultaneously and alleviate working strength.
The optical signal that the related automatic Measurement and analysis instrument of microorganism of the utility model passes the microorganism culturing ware with scanning carries out light/electricity conversion and A/D conversion, again by MICROCOMPUTER PROCESSING, analysis and record, measuring microbial status in the microorganism culturing ware, as the Measurement and analysis of inhibition zone etc.
This instrument mainly is made of measuring system and microsystem.Measuring system comprises mechanical drive, scanning system and Automatic Control Unit, by the CCD scanning technique microbiological specimens is measured automatically.Microsystem comprises general micro computer and printer, the metrical information of measuring apparatus is calculated, is analyzed, and the Measurement and analysis result is shown and print record.
The mechanical drive of measuring system is mainly used in to drive places testee (microorganism culturing ware) movement of bracket.It is to adopt a leading screw to pay the transmission rig of paying with two feed rods, sees figure one.The feed rod axle (2) that the lead screw shaft that leading screw is paid (1) and two feed rods are paid is three parallel shafts, and in the middle of lead screw shaft placed, the feed rod axle was positioned at both sides.Place testee carriage (3) on three parallel shafts.Sliding sleeve on captive nut on the lead screw shaft and the feed rod axle connects with carriage (3) respectively.Lead screw shaft is by direct-current machine (4) driven rotary, and lead screw shaft adopts active the connection with motor shaft.The rotation of lead screw shaft drives testee carriage (3) back and forth tangential movement on two feed rod axles by captive nut.The microorganism culturing ware of putting on the testee carriage (5) is also just along with moving reciprocatingly.Can be placed with tested microbiological specimens in the culture dish.The light that places the led lighting paroxysm of testee carriage top to go out shines the microorganism culturing ware downwards.The lead screw shaft the other end has optical code disk (6).Along with the rotation and the to-and-fro movement of testee carriage of lead screw shaft, the optical code disk circuit sends synchronizing pulse, passes to micro computer and scanning device.Synchronizing pulse gated sweep device switch, scanning device work when making the motion of carriage trace, idle running is returned during the flyback motion.
Scanning system adopts improved hand to hold scanning device (Hand-Scanner), carries out work according to CCD linear array scanning measuring technology.Improved hand is held scanning device, and camera lens is inner and move to the outside to the led lighting battle array (7) of external radiation exposure with being arranged on, and sees figure two.Be that testee places the light path between led lighting battle array and the scanning device camera lens, the optical signal transmission that the led lighting paroxysm goes out is crossed in the tested culture dish and is entered scanner lens (11) again through speculum (10) after the microbiological specimens, after opto-electronic conversion, A/D conversion, take out numerary signal by the microcomputer timing sampling again, calculate, analyze, and the result shown on computer monitor and by the printer prints record.
Automatic Control Unit is made up of power supply and motor logic pilot circuit, photoelectric isolating circuit, monopulse generation circuit, sweep start circuit etc., realizes the automatic control of whole device.
Figure one is a mechanical drive plan structure synoptic diagram.Among the figure, 1-lead screw shaft, 2-feed rod axle, 3-carriage, 4-direct-current motor, 5-microorganism culturing ware, 6-optical code disk.
Figure two is a scanning device optics system schematic.Among the figure, 5-microorganism culturing ware, 7-led lighting battle array, 8-reflective mirror, 9-spectral filter, 10-reflective mirror, 11-camera lens, 12-CCD chip.
The automatic analyzer of microorganism described in the utility model can be widely used in biologicall test and the evaluation of antibiotic quality control in people's medicine, veterinary drug and the pesticide producing, drug quality calibrating and R﹠D institution. Simultaneously, be applicable to Chinese medicine production, drug abuse test, clinical medicine analysis, drug sensitive test, and environmental protection, food, nutriment sterilization class Pharmaceutical Analysis and commodity inspection field.
