Description

Technical Field

[0001] The invention relates to the technical field of urine analysis devices, and in particular to a portable urine analyzer. Background Art

[0002] Urinalysis is a systematic analysis of urine to prevent, diagnose, observe the therapeutic effect and judge the prognosis of urinary, circulatory, liver, gallbladder and endocrine diseases. Urine analyzer is an automated analytical instrument used to detect certain chemical components in urine and is an important tool for automated urine examination in medical laboratories.

[0003] Most of the existing medical urine analyzers are large-scale equipment, such as the automatic urine analyzer disclosed in the existing patent CN208872765U, which includes a strip selection mechanism, a sample adding mechanism, a sample tray, a strip feeding mechanism, a detection mechanism and an output mechanism, etc. The equipment has a complex structure and is relatively expensive. It is not suitable for families to purchase and use at their own expense, nor is it convenient to carry it out for testing at any time.

[0004] Miniaturized household urine testers are a promising development direction. Some small portable urine test instruments have also appeared on the market. For example, the existing patent CN104316470B discloses a household urine analyzer. The test paper is placed on the test paper placement slot of the slide rail. The slide rail can slide back and forth relative to the guide rail. The detection device detects the surface of the test paper during the movement of the test paper to obtain corresponding information.

[0005] The movement of the slide rail of the above-mentioned household urine analyzer needs to rely on gear rack transmission and a motor to provide kinetic energy, which is prone to instrument failure, increasing maintenance risks and operating costs. Summary of the invention

[0006] The invention provides a urine analyzer with exquisite structure and convenient portability. It does not need a motor to control the movement of a test paper, can complete the scanning and detection of the test paper in a static environment, and the test paper holder of the instrument is detachable for easy cleaning.

[0007] In order to achieve the above technical objectives and achieve the above technical results, the present invention solves the above problems through the following technical solutions:

[0010] In the above scheme, an LED light source array is constructed through the light source channel of the array, and a photoelectric conversion tube array is constructed through the photoelectric conversion channel of the array. The light signal emitted by the LED light source is reflected to the corresponding photoelectric conversion tube through the test paper adsorbed with urine. The reflected light signal emitted by the LED light source array will be converted into an electrical signal and transmitted to the control circuit board for identification and displayed on the display screen. The detection process adopts the static LED reflection method without setting up a motor drive. The detection module system composed of the detection channel, light source channel, photoelectric conversion channel, LED light source, and photoelectric conversion tube has a simple structure and rapid detection.

[0011] Furthermore, the test paper holder is a T-shaped structure that is wide at the front and narrow at the back. The test paper slot is opened along the length direction of the test paper holder, and the front end slot is provided with an inclination angle that facilitates the test paper to slide in.

[0012] Furthermore, the display screen adopts a touch liquid crystal display screen, the upper cover is provided with a window which is embedded with the display screen, and the top surface of the upper cover is covered with tempered glass.

[0013] Furthermore, a battery holder for installing alkaline dry batteries is arranged in the battery compartment, and the compartment opening is closed by a detachable battery rear cover.
