Dry type biochemical analyzer

Abstract

The invention discloses a dry type biochemical analyzer belonging to the technical field of biochemical detection equipment. The dry type biochemical analyzer is characterized in that in a mechanical system, a dry sheet sampling position is arranged on an X and Y two-dimensional linear movement platform, two pushing rods are respectively arranged in an X direction of the X and Y two-dimensional linear movement platform, an incubation groove is fixed in front of the pushing rods, a baffle block is arranged in the front end of the incubation groove, and a pushing rod is arranged in a Y direction of the X and Y two-dimensional linear movement platform. In an optical system, (a), an LED (Light Emitting Diode) light source is arranged in an integrating sphere, a lens groove is arranged on an optical axis line of the integrating sphere and a dry sheet; and (b), a rear beam-splitting optical system is located at the underface position vertical to the dry sheet, and a lens group and a grating are arranged on a lower vertical line of the dry sheet. The dry type biochemical analyzer has the beneficial effects that 1, by applying an integrating sphere technology, the problem of difficulty in acquiring a signal due to diffuse reflection is solved, and the precision of an instrument is greatly improved; 2, the instrument is more flexible and is convenient to use; 3, by adopting a rear beam-splitting design, the detection accuracy is improved, and the stability of unit is higher; and 4, the dry type biochemical analyzer is low in cost, small and portable, and high in detection speed and performs detection for 120 tests per hour by applying a multi-channel means; and multiple reagent dry sheets are matched with the instrument, thus the demand of clinical testing is met.

Description

technical field [0001] The invention belongs to the technical field of biochemical testing equipment, and relates to an improvement of a clinical medical testing device. Background technique [0002] Dry chemical testing technology includes dry biochemical analyzers and dry reagent sheets (referred to as dry sheets). Dry sheets are carriers with fixed reagents. , the reagent in the dry film and the analyte in the sample produce a color reaction, put it into a dry biochemical analyzer, and irradiate the incident light from the light source on the dry film after color development, according to the light reflectance on the dry film. The corresponding change in the concentration of the analyte in the sample is calculated. [0003] At present, commercially available dry biochemical analyzers mainly detect by detecting the luminous intensity after the contact between blood and chemical reagents. The optical detection components are composed of light emitting diodes and photocell...
