Premature infant gestational age indicating device

Abstract

The premature infant gestational age indicating device comprises a base and a cover plate, an annular groove is formed in the front end face of the base, a first rotary disc and a second rotary disc are arranged in the annular groove and rotationally connected with the annular groove, a plurality of first pits are formed in the front end face of the first rotary disc in the circumferential direction, and a plurality of second pits are formed in the front end face of the second rotary disc in the circumferential direction. First characters used for indicating the number of weeks are sequentially arranged on the inner end parts of the plurality of first recesses, a plurality of second recesses are circumferentially arranged on the front end surface of the second turntable, and second characters used for indicating the number of days are sequentially arranged on the inner end parts of the plurality of second recesses; the cover plate is fixed to the front end of the base, a first observation hole and a second observation hole are formed in the cover plate, and a receding hole is formed in the cover plate and used for allowing a finger to penetrate through so that the finger can stir the first rotary disc and the second rotary disc to rotate; according to the invention, the gestational age of the premature infant can be conveniently indicated, so that medical staff can conveniently check the gestational age of the premature infant in real time.

Description

technical field [0001] The invention relates to the technical field of gestational age indicating devices, in particular to a gestational age indicating device for premature infants. Background technique [0002] Gestational age refers to the day or week age of the fetus in the uterus. The physical development of the fetus and the maturation of the nervous system in the mother's uterus are carried out in a certain time sequence; medically, the gestational age of less than 37 weeks is called premature infants, premature births. It has become a global public health problem. About 20.6 million premature babies are born every year in the world, accounting for 15.5% of the number of newborns. my country is one of the countries with the largest number of premature births in the world. The required treatment and care needs to be more detailed, such as body temperature management, correct feeding, close observation of changes in the condition, prevention of infection and complications...

AI Technical Summary

Problems solved by technology

[0003] The corrected gestational age of premature infants is calculated by adding the weeks and days after birth to the weeks and days at birth. In clinical work, the corrected gestational age is used to calculate pregnancy The number of weeks is helpful for the assessment of the growth and development of premature infants, the calculation of nutrients and fluid volume, and at the same time, through the real-time grasp of gestational age, rehabilitation care at various stages, such as oral colostrum smearing, oral movement intervention, etc.; but currently In the clinical work, there is a lack of individualized and dedicated corrected gestational age indicator devices for premature infants, and there is no eye-catching gestational age mark beside the bed to inform other medical staff in the ward of the current gestational age of the premature infant, that is, clinical medical workers need to rely on the daily Calculate and record, not only has the disadvantage of low work efficiency, but also affects the development of fine management of premature infants
