A method and device for measuring the upper and lower parts of infants and young children

Abstract

The invention discloses a method and an instrument for measuring lengths of the upper part and the lower part of an infant and belongs to the technical field of medical measurement instruments. The instrument comprises a rectangular measuring board with scales on one edge in the length direction of the measuring board, and is characterized by further comprising a support, wherein a slider is arranged at one end of the support, a chute is formed in the measuring board in the length direction, the slider is assembled in the chute, a swing arm perpendicular to the length direction of the measuring board is articulated to the other end of the support, and the other end of the swing arm is bent; a first sliding plate and a second sliding plate which are perpendicular to the length direction of the measuring board are further mounted in the chute and located on two sides of the support. The instrument allows the infant to lie flat, and accordingly, the degree of errors caused due to incooperation of the infant is reduced; the tail end of the swing arm can reach the upper edge of pubic symphysis, the scale value, corresponding to the upper edge of pubic symphysis, on the measuring board can be accurately read out, accordingly, the lengths of the upper part and the lower part of the infant can be accurately calculated, and accurate data are provided for clinical diagnosis.

Description

technical field [0001] The invention belongs to the technical field of medical measuring instruments, and in particular relates to a method and an instrument for measuring the upper and lower parts of an infant. Background technique [0002] The length of the human body is the sum of the lengths of the head, spine and lower limbs. During the growth process of the human body, the development speed of these three parts is not the same. Generally, the head grows the fastest in the first year after birth, followed by the spine; and the lower limbs grow the fastest after puberty, so the proportions of the head, spine and lower limbs are different at different ages. [0003] It has been clinically proven that some diseases can affect the growth rate of the head, spine and lower limbs, resulting in an imbalance in the proportion of the various parts of the human body to the length of the body. That is to say, by regularly measuring the length of each part of the human body, it can...

Problems solved by technology

In this method, there are deviations in the measurement site itself, and infants who do not cooperate cannot maintain the correct sitting posture, or even sit up, which brings great difficulties to the measurement of sitting height, resulting in extremely inaccurate measurement data and affecting clinical diagnosis results.
