A kind of turbidity meter and liquid analysis equipment

Abstract

The invention discloses a turbidity meter and liquid analysis equipment. The turbidimeter includes a casing, and a sealed space is arranged in the casing; a transparent container is arranged in the sealed space; a sample suction tube, one end of the sample suction tube is connected to the transparent The container is connected, and the other end extends out of the casing; the light emitting unit is arranged in the sealed space, and the light emitting unit emits light to the transparent container. At least the first and second photoelectric conversion units, the first and second photoelectric conversion units are both arranged in the sealed space, the first photoelectric conversion unit receives the direct light emitted by the light emitting unit, and converts the received direct light into the second An electrical signal; the second photoelectric conversion unit receives the scattered light emitted by the light-emitting unit that passes through the transparent container and is scattered, and converts the received scattered light into a second electrical signal; the processing unit, according to the first electrical signal and the second electrical signal The signal calculates the turbidity of the measured liquid. Through the above method, the present invention realizes rapid detection of liquid turbidity.

Description

technical field [0001] The invention relates to the technical field of liquid detection, in particular to a turbidity meter and liquid analysis equipment. Background technique [0002] A turbidimeter is a device used to detect the turbidity of a liquid, where the turbidity of the liquid is due to the insoluble suspended matter contained in the liquid. [0003] In the medical field, it is often necessary to detect the turbidity of a patient's urine to determine the condition of the patient. At present, the method for detecting the turbidity of urine is to observe manually by inspectors, and judge the turbidity of urine according to the observation results. The method of manually judging the urine turbidity requires the test personnel to be in close contact with the urine sample, which is unhygienic, unsafe, and low in efficiency. Moreover, when a large number of urine samples need to be tested, the test personnel manually take out the sample for observation and record the tu...

Problems solved by technology

The method of manually judging the urine turbidity requires the test personnel to be in close contact with the urine sample, which is unhygienic, unsafe, and low in efficiency. Moreover, when a large number of urine samples need to be tested, the test personnel manually take out the sample for observation and record the turbidity. It is very easy to mistake the sequence of urine samples before and after, resulting in serious accidents of dislocation of test results.

[0004] At present, there are also liquid turbidity equipment, but this liquid turbidity equipment cannot perform continuous and rapid detection on batches of urine samples in hospitals, and the traditional liquid turbidity equipment also has the following shortcomings:

[0005] 1. Traditional liquid turbidity equipment cannot detect trace liquid samples;

[0006] 2. The liquid turbidity equipment with reliable performance needs to collect and calculate the transmitted light intensity and scattered light intensity of the specimen. Traditional photoelectric converters, digital-to-analog conversion circuits and signal shielding measures all result in a relatively large volume of the turbidimeter. Difficult to integrate and work with medical automated testing instruments;

[0007] 3. No matter whether the traditional liquid turbidity equipment adopts the input type or the online circulation detection mode, it cannot meet the requirements of continuous detection of large batches of samples in hospitals and the simultaneous elimination of cross-contamination between samples.
