Abstract
The utility model discloses a rapid urine diagnosis analyzer, relating to an analyzer which uses a rapid diagnosis reagent to detect metabolite discharge of cancer cells in a human body. A urine sample is light penetrated by a sensor, and after received by a semiconductor color sensitive element, the sample is transmitted into a computer through a logarithmic amplifier, an amplifier and an analogue-digital conversion circuit; for the received urine data, the computer refers to a relationship curve of a urine diagnostic reagent previously stored in the computer to calculate and analysis, then export a datum; a detecting result is displayed by a display. The utility model has advanced detecting mechanism, simple operation, stable performance, small size and convenient carrying.
Description
The utility model relates to a kind of rapid detection, the analyser of cancer cell metabolin discharging in the diagnosis human body.
In existing urine detection technology, the discharging of cancer cell metabolin is to add change color before and after the reagent by the visual inspection urine in the human body, and relatively differentiates with colour atla.Because the error of people's vision outwardness can't be sought unity of standard to testing result, therefore, directly has influence on the diagnosis to the state of an illness.
The purpose of this utility model is to provide a kind of detection mechanism advanced person, and examination criteria is unified, and is simple to operate, and stable performance can detect the electronic analytical instrument that urine adds reagent front and back change color rapidly.
The utility model is achieved in that it mainly by sensor, display, and the button part, logarithmic amplifier, amplifier, analog to digital conversion circuit, computing machine partly constitutes.In sensor, adopted the semiconductor colour sensitive element, the stoste of urine is successively put into sensor with the urine that is added with reagent during detection, sensor is passed to logarithmic amplifier with the sample color signal, the voltage signal that is directly proportional with it that obtains after logarithmic amplifier is taken the logarithm difference is delivered to amplifier and is amplified, obtain the voltage of the conforming corresponding color that each instrument has, and send analog to digital conversion circuit to and convert digital signal to and send computing machine to partly.Computing machine is partly based on the 89C51 single card microcomputer, store in it urine diagnostic reagent relation curve that obtains through a large amount of clinical testings is arranged, computing machine shows urine stoste that detects and the data that are added with the urine of reagent with result's numeral with 0～100 on display that will obtain after relation curve is compared, for the state of an illness is diagnosed.
The utility model can be measured the color of urine sample with unified standard owing to adopted the semiconductor colour sensitive element, has avoided the error that detects by an unaided eye and produce.Storing in computing machine has the urine diagnostic reagent relation curve that obtains through a large amount of clinical testings and can compare, analyze and provide measurement result fast with this result that urine is measured.Effect of the present utility model is that significantly it is not only diagnosed fast, and the result is accurate and apparatus structure is reasonable, and volume is little, and is easy to carry, can be widely used.
Accompanying drawing is the utility model embodiment, wherein;
Fig. 1. the utility model synoptic diagram;
Fig. 2. the utility model principle of work synoptic diagram;
Fig. 3. the sensor construction synoptic diagram;
Fig. 4. the amplifier circuit synoptic diagram.
Now in conjunction with the accompanying drawings the utility model is further described;
The utility model is mainly by sensor 1, and display 2, button partly 3, logarithmic amplifier 4, amplifier 5, analog to digital conversion circuit 6, computing machine partly 7 constitute, and wherein: sensor 1 is by test tube flat 8, semiconductor colour sensitive element 9, and rubber washer 10, panchromatic light source 11 constitutes.Have at the middle part of test tube flat 8 vertically to the test tube hole, insert test tube during measurement, its diameter is a bit larger tham the outer warp of test tube, rubber washer 10 is located at the bottom of the hole.Have more than at the bottom of the bottom of test tube flat is positioned at the test tube hole level to through hole, be respectively equipped with panchromatic light source 11, semiconductor colour sensitive element 9 at the through hole two ends.Before the test tube that sample is housed does not insert, the panchromatic photosignal of semiconductor colour sensitive element 9 outputs, insert the test tube of urine sample is housed after, the electric signal of semiconductor colour sensitive element 9 output sample colors.
Partly 3 be provided with " self check ", " detection ", the Reset button at button.
The utility model is started working after the energized, panchromatic light source 11 is bright, display 2 shows " P-", by behind " self check " button, the display demonstration "---", at this moment panchromatic light signal becomes electric signal through semiconductor colour sensitive element 9 and is transferred to logarithmic amplifier 4, gets difference after logarithmic amplifier 4 is taken the logarithm to it again and obtains delivering to amplifier 5 with the electric signal that it is directly proportional and amplify and send behind the voltage that obtains corresponding sample color analog to digital conversion circuit 6 to convert numeral to be delivered to computing machine partly 7 for new number.Computing machine is to its continuous sampling, and after sampling in average 20 seconds finished, display 2 flickers showed " 1-", and the prompting self check finishes, and can put into sample (former urine) for the first time in sensor 1.After for the first time sample is put and is finished, again by " detection " button, the color of the former urine of sample through above-mentioned testing process by computer sampling, internal memory.Sampling for the first time finishes, and display 2 flickers show " 2-", and prompting can be put into sample (being added with the urine of reagent) for the second time.After sample has inserted for the second time, by " detection " button, the color signal that is added with urine behind the reagent still after above-mentioned testing process is by computer sampling, internal memory computing machine calculate with reference to the urine diagnostic reagent relation curve of storing in advance within it immediately, analyze the result of twice detection, the data that provide " 0～100) " show on display 2, the report diagnostic result.Press the Reset button, make computing machine reenter standby condition, begin new detection.
