Millimeter-wave human body temperature measuring device

Abstract

The invention relates to application of a millimeter wave technology and particularly relates to a millimeter wave human body temperature measuring device. The device comprises a millimeter wave antenna, a first millimeter wave amplifier, a first single-pole double-throw switch, a second millimeter wave amplifier, a millimeter wave detector, a second single-pole double-throw switch, a comparison amplifier and a reference load, wherein the millimeter wave antenna, the first millimeter wave amplifier, the first single-pole double-throw switch, the second millimeter wave amplifier, the millimeterwave detector, the second single-pole double-throw switch and the comparison amplifier are connected in sequence, and the reference load is further connected with the first single-pole double-throw switch. The device is advantaged in that the device does not need to be aligned with exposed skin, can penetrate through clothes of a human body, carries out non-contact body temperature measurement ona human body, has no mercury pollution hidden danger, and is rapid in measurement and simple and convenient in reading.

Description

technical field [0001] The invention relates to the application of millimeter wave technology, in particular to a millimeter wave human body temperature measuring device. Background technique [0002] Human body temperature measurement is becoming more and more important in the monitoring of the physiological state of the human body, medical treatment and health care, and epidemic prevention and control. During the development of various human body temperature measurement technologies, the following methods have been widely used. [0003] Glass thermometers based on physical methods: The working substance of glass thermometers is generally mercury. Its glass bubble volume is much larger than the volume of the thin tube above. Due to the influence of body temperature, the mercury in the bubble changes slightly, and the expansion of the volume of mercury makes the length of the mercury column in the tube change obviously. When it reaches thermal equilibrium with the body tem...

AI Technical Summary

Problems solved by technology

[0006] (1) The defects of the glass thermometer are also obvious, such as easy to break, the possibility of mercury contamination, the measurement time is relatively long, it is inconvenient to use for acutely ill patients, the elderly, infants, etc., and the reading is troublesome, etc.

[0007] (2) The disadvantage of infrared thermometers is that they are greatly affected by the surrounding environment, cannot penetrate human clothing, and can only measure the temperature of human exposed skin.
