An automatic measuring instrument for infant head circumference

Abstract

The invention relates to an infant head circumference automatic measurer which comprises a head circumference frame, an inner left airbag, an inner right airbag, an outer left airbag, an outer right airbag, a double-throw switch, a code scanner, a data conversion and acquisition unit and a data processing and display unit, wherein the inner left airbag and inner right airbag are embedded to the inside of the head circumference frame and connected with an inner inflation unit; the outer left airbag and outer right airbag are embedded to the outside of the head circumference frame and connectedwith an outer inflation unit; the measurement output end of the double-throw switch is connected with the inner inflation unit and data conversion and acquisition unit; the backup output end of the double-throw switch is connected with the outer inflation unit; and the signal output ends of the data conversion and acquisition unit and code scanner are connected with the corresponding signal receiving end of the data processing and display unit. Compared with the existing manual measurement method, the invention has the advantages of higher measurement speed, higher measurement accuracy and accurate and reliable result, and enhances the efficiency for physical examination of infants.

Description

technical field [0001] The invention relates to the measurement of developmental parameters of human limbs, in particular to an automatic measuring instrument for head circumference of infants. Background technique [0002] The size of the head circumference of an infant reflects the developmental degree of the brain and skull, and is a sensitive indicator of intelligence and brain development. At present, when each infant and child is carried out for health care, the head circumference size of the brain and skull of the infant is manually measured by the medical staff with a soft ruler. So far, there is no electrical equipment to automatically measure the head circumference, and it is impossible to realize the automatic collection of the size of the head circumference by the computer, resulting in heavy work, many errors, poor accuracy and low efficiency for medical staff. Contents of the invention [0003] The invention provides an automatic measuring instrument for hea...
