Special spectrograph for neonatal jaundice blue light therapeutic instrument and optical mechanism design method of special spectrograph

Abstract

The invention discloses a special spectrometer for a neonatal jaundice blue light therapeutic instrument and an optical mechanism design method of the special spectrograph. The special spectrometer comprises a box body, an optical mechanism located in the box body and a drive circuit module, wherein a slit for light transmission is formed in the top surface of the box body, and the optical mechanism comprises a collimating mirror, a grating, a focusing mirror and a CCD detection module; and the drive circuit module comprises a signal conditioning circuit module, an ADC analog-to-digital converter, an FPGA system, a USB control chip and an upper computer which are connected in sequence. According to the special spectrograph applied to the blue light therapeutic instrument, by changing the position of the slit and the corresponding design of the optical mechanism, the redundant function is omitted, the equipment size is reduced, the cost is reduced, the responsibility to the wavelength within the blue light range is improved, the required wavelength can be better matched, and the using effect is increased.

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 a blue light treatment instrument for neonatal jaundice and a design method for its light source spectroscopic system. Background technique [0002] Neonatal jaundice is the accumulation of excessive bilirubin in the body during the neonatal period, which causes yellow symptoms in the skin, mucous membrane, sclera and other parts of the body. If not treated in time, it can cause mental retardation, hearing impairment, death or permanent nervous system 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 newborn's serum bilirubin content does not exceed an allowable range, and it will subside by feeding and excretion within a short time after birth. For those that ex...

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
