Abstract

The utility model relates to a urine analysis instrument paper bar testing head translational moving transfer device, comprising an optics testing head paper bar transfer electric motor controlling circuit. The paper bar testing head of the paper bar transfer device is a fixed testing head which is directly fixed on the testing position and need not to be driven by the gear of the electric motor. The paper bar transfer device is a translational moving transfer device, depending on the electric motor driving the gear to move the dental plate, delivering the paper bar to the required testing place, sending the testing bar to a collecting box after test. According to the fact that, driven by two motors, the fixed testing head of the paper bar translates to test, the utility model carves up tooth space on rectangle dental plate in equidistance, and uses the mainboard CPU drive device to control step motor and testing head to make nicety analysis on urine test paper. The urine test paper can be placed at any time, which realizes speedability of continuously test.

Description

Urine Analyzer test strips measuring head flatly moving type conveyer

Technical field

The utility model relates to the Urine Analyzer that a kind of medical fast detecting is used, and particularly a kind of Urine Analyzer test strips measuring head flatly moving type conveyer belongs to International Classification of Patents G01N33/50 " chemical analysis of biological substance " technical field.

Background technology

The test of existing Urine Analyzer test strips, conveyer be common have following several:

1, proving installation: every Urine Analyzer flatly moving type proving installation, rely on motor, gear, belt to drive gauge head and detect common type: Uritest 200 (A) type, 300 types, 500 types, the auspicious H-100 type of enlightening, H-300 type, H-500 type, Thyrite 50,100,500 types.

2, conveyer: wall scroll is placed, every Urine Analyzer has only a test strips standing groove, and placing needs manually to take off after the test strips test finishes, and test speed is slower, general 60/hour, the auspicious H-50 type of common type enlightening, H-100 type, Thyrite 50,100 types etc.

This shows that existing Urine Analyzer proving installation all is to adopt campaign-styled measuring head to detect, run-in index transmits test strips.First kind of mode be owing to rely on motor, gear, belt to drive gauge head and detect, thus often follow noise when detecting, and influenced by motor, gear, belt equal life to occur noise easily, after the motor gear damage, test can't be carried out.Though second way instrument conveyer structure is simple, test speed is slower, does not satisfy the big client of specimen amount.

Summary of the invention

The purpose of this utility model, be to overcome in the existing Urine Analyzer test strips detection and noise and gauge head fault occur, and the problem of test strips conveyer structural design test speed, provide a kind of test speed fast, the Urine Analyzer test strips measuring head flatly moving type conveyer of measured value good reproducibility.

The purpose of this utility model is achieved through the following technical solutions.

A kind of Urine Analyzer test strips measuring head flatly moving type conveyer comprises optical detecting head, test strips, transmission motor, control circuit and paper slip conveyer composition.Control circuit links to each other with the transmission motor with optical detecting head respectively.

Described test strips measuring head device is a kind of fixed gauge head, need not motor gear and drives, and directly is fixed on test strips and detects on the examination position; Described test strips conveyer is a kind of flatly moving type conveyer, relies on motor driven gear to make the tooth plate operation that test strips is delivered to the appointment detection zone, and to be detected finishing delivered in the collection box.

Adopt technical solutions of the utility model, described Urine Analyzer test strips measuring head and conveyer, utilize fixedly gauge head detection characteristics of Dual-motors Driving translation paper slip, equidistant division space width on the rectangle tooth plate, utilize motherboard cpu driving device controls stepper motor and gauge head that urine test paper is accurately analyzed, get back to start bit when thruster simultaneously and can place the urine test paper bar at any time, realize the rapidity of follow-on test, therefore, this practical new solution described Urine Analyzer test strips measuring head and conveyer characteristics are: superior measuring head adopts every sheet of mode of integrated optical filter to divide 16 points.Characteristics one, employing high precision color sensor identification colors.Recognition principle: sensor the is integrated optical filter of three kinds of colors, by selection to sensor control can change optical filter.The different colours reflection of light intensity that (optical filter has three kinds of colors of red, green, blue) can survey under different optical filter modes, its consistance is fairly good in the circuit, dependable performance stable because optical filter is integrated in so calculate three kinds of reflection of light rates respectively.The second, adopt pure white high-brightness LED (＞8000 light intensity) as light source.1. light source is a pure white, so the red, green, blue intensity composition in its emission light is impartial.The light intensity of the red, green, blue color after reflecting by color lump like this could truly reflect the color on the color lump.2. because LED is so that cold light source device failure rate is extremely low.Fixing gauge head, the conveyer low noise of translation, easy to use, test speed fast, test result consistance good reproducibility, long service life.
