Description
Technical Field
The invention relates to the field of medical machinery, in particular to a urine detector and a detection method thereof.
Background
The urine detector is an automatic instrument for measuring certain chemical components in urine, is an important tool for automatically examining urine in a medical laboratory, and has the advantages of simplicity in operation, rapidness and the like. However, the accuracy of the automatic analysis result is directly affected by improper use of the detector, many intermediate links and influencing factors, which not only causes error of the experimental result, but also delays diagnosis, so that the operator is required to fully understand the knowledge of the principle, performance, attention and influencing factors of the automatic instrument, and correctly use the automatic instrument, so that the result obtained by the urine analyzer is more reliable and accurate.
In the 50 s, some people adopt a single dry chemical test strip method to measure protein and glucose in urine, and the change of the test strip color is compared with that of a standard plate by using naked eyes to obtain corresponding values. In the 80 s, due to the high development and wide use of computer technology, the automatic urine analyzer was rapidly developed and gradually developed from the original semi-automation to the present full-automation. Urine analyzers are often classified into two categories depending on the test items: firstly, it is mainly used for 8-11 items of screening combined urine test tapes for first-diagnosis patient and health examination. The 8 detection items comprise protein, glucose, PH, ketone body, bilirubin, urobilinogen, trapped blood and nitrite; the 9 items of examination were added to the urine leukocyte examination in addition to the 8 examinations described above. The urine specific density examination is added on the basis of the 10 items of urine analyzer detection items and the 9 items. The vitamin C examination is added to 11 detection items. ② mainly used for observing the curative effect of diagnosed diseases, for example, PH, protein and occult blood (erythrocyte) combined test strips can be used for kidney diseases; testing the diabetes by using a PH, sugar and ketone body combination test strip; the liver disease patient uses bilirubin and urobilinogen combined test strip. The instrument is controlled by a microcomputer, and a spherical integrator is used for receiving the color change on a test strip in a mode of reflecting light with two wavelengths to perform semi-quantitative measurement. The reagent belt is provided with a plurality of reagent pads containing various reagents, which respectively and independently react with corresponding components in urine to display different colors, the depth of the color is in proportional relation with the political power of a certain component in the urine, and the reagent belt is also provided with another 'compensation pad' as the background color of the urine, thereby compensating the colored urine and the errors of the apparatus change to be born. The reagent belt with adsorbed urine is placed in the colorimetric groove of the instrument, various reagent pads which have produced chemical reactions on the reagent belt are irradiated by a light source, the reflected light is received by the spherical integrator, the photoelectric tube of the spherical integrator is irradiated by the reflected dual-wavelength light (the measuring light passing through the filter disc and a beam of reference light), and the selection of each wavelength is determined by the detection item. The instrument automatically calculates the reflectivity according to the following formula, then compares with a standard curve, and automatically finds and prints corresponding results of various components, wherein the content of a certain component in urine is high, the reflected light of the corresponding reagent pad is darker, and otherwise, the reflected light is stronger.
The reflectivity is expressed as follows: r (%) = Tm.Cs/TsCm × 100%
Wherein R (%) is reflectance; tm is the reflection intensity of the reagent pad to the measuring wavelength; ts is the reflection intensity of the reagent pad for the reference wavelength; cm is the reflection intensity of the alignment pad to the measured defect length; cs is the reflection intensity of the calibration versus the reference wavelength.
In the prior art, the conventional detection of urine is usually carried out by adopting a manual test paper, so that the labor amount of medical staff is increased and the operating environment of the medical staff is damaged; on the other hand, the manual inspection mode can only perform the detection of one sample at a time, which causes the low efficiency and the prolonged inspection time.
In addition, the current urine detection is divided into a urine routine type chemical reaction examination and a sediment type physical detection mode, different detection modes are often required for different patients, or the detection of the different detection modes and the detection of the sediment mode are carried out on different devices in the prior art, so that the operation of medical staff is inconvenient, and the time of the patients is wasted.
