A special spectrometer for neonatal jaundice blue light therapy instrument and its optical mechanism design method

Abstract

The invention discloses a special spectrometer for neonatal jaundice blue light treatment instrument and its optical mechanism design method, which comprises a box body, an optical mechanism located in the box body and a drive circuit module, and the top surface of the box body is provided with a light-transmitting hole. The slit, the optical mechanism includes a collimating mirror, a grating, a focusing mirror and a CCD detection module, and the driving circuit module includes a signal conditioning circuit module, an ADC analog-to-digital converter, an FPGA system, a USB control chip and a host computer connected in sequence. The present invention designs a special spectrometer applied to the blue light therapy instrument. By changing the position of the slit and the corresponding design of the optical mechanism, it not only saves the redundant function, reduces the volume of the equipment, reduces the cost, but also improves the blue light range. The responsivity of the wavelength within can better match the required wavelength and improve the use effect.

Description

technical field [0001] The invention belongs to the field of medical equipment and relates to quality detection technology, in particular to a special spectrometer used for neonatal jaundice blue light treatment instrument and a design method of a light source spectroscopic system thereof. Background technique [0002] Neonatal jaundice is the excessive accumulation of bilirubin in the body during the neonatal period, causing yellow symptoms in the skin, mucous membranes, sclera and other parts of the whole body. If not treated in time, it can cause mental retardation, hearing impairment, death or permanent neurological sequelae. [0003] Neonatal jaundice is a common disease of newborns, which can usually be divided into physiological jaundice and pathological jaundice. General physiological jaundice means that the serum bilirubin content of newborns does not exceed an allowable range, and it will subside on its own through feeding and excretion within a short time after bi...

AI Technical Summary

Problems solved by technology

[0005] Current status of neonatal blue light therapy in the prior art: most of the existing spectrometer models on the market are general-purpose, and some of their functions are too redundant to be applied to the detection of blue light therapy; the wavelength responsivity of the photodetector CCD used in the spectrometer cannot Match the required wavelength; the volume of the spectrometer is slightly larger than that required by the equipment, and the detection device cannot be optimized structurally
