Embodiment Construction

[0020] The sample detection system of the miniature biochemical detector includes an optical system, a spectrum scanning system and a temperature control system, which are integrated and assembled in a chassis.

[0021] see figure 1 , The spectral scanning system includes a sample cell 5 , a sample cell rack 4 , a linear guide rail 9 , a linear stepper motor 10 , a slider 16 , and a photoelectric limit switch 12 . The sample pool 5 includes 8 pools, which are arranged in a straight line and fixed on the sample pool rack 4, and the sample pool rack 4 can move along the linear guide rail 9 driven by a stepping motor. Slider 16 is arranged on the linear guide rail 9, and slide block 16 is connected with the connecting support structure fixed on the sample pool tank frame, and the connecting support structure and the driving nut on the linear stepper motor screw rod 15 are fixed by screws, thereby driving the sample pool tank frame Moving linearly along the linear guide rail,...

Abstract

The invention relates to a sample detecting system of a micro biochemical detection instrument. The sample detecting system comprises an optical system, a spectrum scanning system and a temperature control system, wherein the detecting system is controlled by an embedded type ARM9S3C2410 in real time, so that the optical system, the spectrum scanning system and the temperature control system coordinately cooperate to rapidly detect biochemical indexes in real time. The sample detecting system can realize pulse positioning and precise and random positioning of various sample chambers, has the characteristics of simple structure, small size, convenience to carry, low power consumption and the like, and is widely applied to national defense, after-calamity emergency treatment, biochemistry, clinical medicine, environment science and the like.

Description

technical field [0001] The invention belongs to the technical field of analytical instruments, in particular to a sample detection system of a miniature biochemical detector. Background technique [0002] The biochemical analyzer is an essential and important testing instrument for clinical examination. It determines the biochemical indicators of the human body such as K by measuring the blood or body fluid of the human body. + 、Na + , Cl - , Hb, TCO 2 , CRE, Glu, etc. Because traditional biochemical analyzers mostly use optical filters or grating monochromators for light splitting, continuous wavelength detection cannot be achieved, and the detection system has many limitations such as large volume, large power consumption, complex structure and inconvenient maintenance, etc., which cannot meet the post-disaster site requirements. First aid and battlefield rescue of the wounded demand background. The micro-spectrometer-based miniature biochemical detector detection ...
