Description

Urine analysis device

Technical Field

The utility model relates to a medical device field, concretely relates to urine analysis device.

Background

Urinalysis is also called urinalysis. The urine is analyzed to achieve the purposes of preventing urinary, circulatory, hepatic, biliary, endocrine and other diseases, observing diagnosis and treatment effects, judging prognosis and the like. The conventional urine analyzer adopts a color sensor to perform segment-by-segment detection, and has a long and narrow scanning channel, a narrow image scanning range and a low detection speed.

SUMMERY OF THE UTILITY MODEL

The utility model provides a solve above-mentioned technical problem and provide a urine analysis device.

The utility model discloses a following technical scheme realizes:

the urine analysis device comprises urine test paper, an image acquisition device and an analysis module, wherein the image acquisition device is used for acquiring image information of the urine test paper, the analysis module is used for detecting and analyzing urine according to the image information, the image acquisition device is a CMOS image sensor, and the urine test paper is multiple and is arranged in an array. According to the scheme, the CMOS image sensor is adopted as the image acquisition device, the advantages of wide image scanning range and high frame scanning speed of the CMOS image sensor are fully utilized, all samples to be detected can be rapidly scanned within a short time, the problem that the conventional urine analyzer adopts a color sensor to gradually detect the samples slowly in a sectional mode is solved, and the detection speed of the analyzer is greatly improved. The image color acuity of the CMOS image sensor can reflect the color difference more truly through the change of pixel point data, the actual color is identified more truly through the reaction of the color blocks of the urine test paper, and the accuracy of the detection result is finally guaranteed by combining with the clinical indexes of corresponding urine detection items. The urine test paper is arranged in an array, and the array arrangement can realize integral one-time scanning detection in a smaller detection unit area, so that the problem that a detection scanning channel of a conventional urine analyzer is long and narrow is solved, the overall dimension of the whole instrument is convenient to reduce, and the instrument is light in weight and more portable.

Preferably, the urine dipsticks are arranged in a 4 x 4 matrix.

Preferably, the CMOS image sensor employs a chip GC 0308.

The utility model discloses, because circuit connection structure and principle between analysis module and the image acquisition device are the same with prior art, the utility model discloses an invention point lies in adopting CMOS image sensor to replace the sensor of original single color lump collection and be equipped with supporting array test paper to realize once only gathering the detection when a plurality of samples, therefore just do not do the elaboration to foretell circuit structure and principle here.

Compared with the prior art, the utility model, following advantage and beneficial effect have:

1. the utility model discloses a CMOS image sensor improves scanning speed, detection speed and testing result's rate of accuracy as image acquisition device.

2. The utility model discloses a urine test paper becomes the array and arranges, and the array is arranged and can be realized the disposable scanning of whole and detect in less detection unit area, has solved the long and narrow problem of detection scanning channel of conventional urine analysis appearance, is convenient for reduce the overall dimension of complete machine, makes instrument complete machine light in weight, and is more portable.
