Constant temperature control device and method of urine analyzer

Abstract

The invention discloses a constant temperature control device and method of a urine analyzer. A sealing cover of the constant temperature control device is disposed over the position, between a test strip drip sample area and a detecting area, of a conveying belt of the urine analyzer. A radiator assembly is mounted in the sealing cover in an embedded mode. Semiconductor refrigerating chips of theradiator assembly are horizontally disposed in the sealing cover. Upper radiating fins and an upper radiating fan are mounted above the semiconductor refrigerating chips. Lower radiating fins and a lower radiating fan are mounted below the semiconductor refrigerating chips. Temperature and humidity sensors are disposed on the inner side of the sealing cover, and the output ends of the temperatureand humidity sensors are connected with a control unit. A temperature control output end of the control unit is connected with the semiconductor refrigerating chips through a semiconductor driving circuit. A wind control output end of the control unit is connected with the upper radiating fan and the lower radiating fan. By means of the constant temperature control device and method of the urineanalyzer, the temperature in an area where a urine test strip movement trajectory is located can be controlled within a constant small change range, and a reliable and proper constant temperature environment is provided for the reaction of a urine test strip and urine.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a constant temperature control device and method for a urine analyzer. Background technique [0002] Urine testing is one of the three routine items of modern medical clinical testing, and plays a very important role in the diagnosis of diseases. Dry chemical urine analyzer is a special instrument for clinical urine testing used in conjunction with dry chemical test paper. It uses reflective photoelectric colorimetry to measure urine analysis test strips soaked in urine, and converts them into semi-quantitative results of corresponding items. During the transfer of the urine test strip to the test after dropping the sample, the temperature has an impact on the dry test result. However, in the existing common automatic urine analyzers, there is no device to control the temperature in the area where the urine test strip is located during the process of transferring the uri...
