Abstract
The utility model provides a liquid level probing and bar code scanning device. The liquid level probing and bar code scanning device comprises an ultrasonic sensor, a bar code scanner, a data processing circuit and a test tube rack, wherein the ultrasonic sensor is arranged above the test tube rack correspondingly to test tube openings in the test tube rack, the bar code scanner is arranged beside the test tube rack correspondingly to bar codes on the outer walls of test tubes in the test tube rack, and the ultrasonic sensor and the electrical signal output end of the bar code scanner are respectively connected with the input end of the data processing circuit. The liquid level probing and bar code scanning device improves accuracy as well as rapidity of liquid level measuring, and eliminates crossed pollution in measuring.
Description
Technical field
The utility model relates in the medical biochemical analysis, to the level detection and the bar code scanner of test sample and reagent.
Background technology
Biochemical analysis is the method that laboratory and clinical diagnosis are adopted usually, need quantitatively draw respectively detected sample and reagent, mixing, operation such as hatches, and need measure the liquid level (being capacity) of encode different samples and reagent in operation.
Existing level detection has electric capacity and pressure sensing type dual mode, and the detection speed of this dual mode is slow, and accuracy of detection also is subjected to the influence of class of liquids, transducer sensitivity, environment temperature.Particularly pick-up unit all needs to contact liquid level, causes cross pollution easily.Also need after the Level Detection bar code on the test tube is scanned identification, this has just more reduced detection speed, has increased the detection cost.
Summary of the invention
The utility model is in order to solve in the present Biochemical Analyzer, to the level detection of the sample of injecting tube and reagent and bar code scan poor accuracy, the slow existing technical matters of operating rate, develop a kind of with ultrasonic listening liquid level and scanning is carried out simultaneously to test tube bar code device.
According to above-mentioned purpose, the utility model provides a kind of level detection and bar code scanner, comprise ultrasonic sensor, bar-code scanner, data processing circuit and test tube rack, wherein ultrasonic sensor is installed in the test tube rack top, and correspondence is placed in the test tube mouth of pipe in the test tube rack; Bar-code scanner is installed in the test tube rack side, and correspondence places the bar code of the test tube outer wall of test tube rack; The electrical signal of ultrasonic sensor, bar-code scanner is connected with the input end of data processing circuit respectively.
The utility model is owing to adopted above technical measures.The accuracy and the rapidity of level gauging have been improved; Cross pollution when having stopped level gauging; Capacity is corresponding one by one with coding, has improved reliability; Shortened the time of the operation of level detection and bar code scan.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, it is the device of liquid level and bar code in a kind of test tubes simultaneously in the biochemical analysis, form by ultrasonic sensor 1, bar-code scanner 2, data processing circuit CPU and test tube rack 3, wherein ultrasonic sensor 1 is installed in test tube rack 3 tops, correspondence is placed in test tube 4 mouths of pipe in the test tube rack 3, bar-code scanner 2 is installed in test tube rack 3 sides, corresponding to the bar code 5 on test tube 4 outer walls that are placed in the test tube rack 3.
When device starts operation, ultrasonic sensor 1 sends ultrasound wave after test tube 4 is run into liquid level, because of the liquid level reflection produces electric signal, and because of ultrasonic sensor 1 electric signal different with the different generations of liquid level distance, input data processing circuit CPU carries out being transformed into corresponding liquid level after the data processing, i.e. the liquid capacity that injected of test tube 4.Simultaneously, the laser that bar-code scanner 2 sends is run into the bar code 5 on test tube 4 outer walls, also with corresponding electric signal input data processing circuit CPU, has just finished the detection of the sample reagent volumes that this bar code test tube 4 injected.Then, test tube rack 3 moves forward under the transmission of device, then carries out the Level Detection of next test tube 4.
