Abstract
The utility model discloses an infrared radiation type thermometer, which measures the human body temperature according to the infrared radiation principle of the human body. When measuring temperature, the utility model needs not to contact the human body surface completely and can measure rapidly in only 1 to 2 seconds. Digital display, latch and reading are convenient and visual. The utility model is characterized in that a probe 1 is provided with a rotary inner cavity; a via hole at the connecting point of the cavity and a shell is provided with an infrared crystal lens 5; a lens axis is over against a pyroelectric detector 4. The probe of the utility model can be forehead type probe or ear plug type probe, and is suitable for various detected objects particularly for babies or the old, the weak, the sick and the disabled.
Description
The utility model belongs to a kind of clinical thermometer, specifically by surveying human infrared radiation, through circuit conversion display digit formula temperature value.
At present, the mercury formula body temperature that people use always at first is will fully contact with human body when thermometric in respect of following shortcoming, places the oxter, oral cavity or anus, heat balance time is long, uses inconvenience, particularly infant, the old,weak,sick and disabled person is more felt difficult, secondly the test result reading is not directly perceived, reading error is big, and particularly thermal media mercury belongs to toxic metals, and damaged back is poisoned bigger.Also have a kind of adhesive film type clinical thermometer, serviceable life is short, low precision.
The purpose of this utility model is to disclose a kind of Infrared Radiation Human-Body Thermometer, produces infrared radiation according to human body, measures the radiation that human body sends with photodetector, and then is converted to the human body actual temperature value.
Below with reference to embodiment description of drawings technical scheme and details thereof.
Fig. 1 is the utility model embodiment 1 structural drawing.
Fig. 2 is the utility model ear type probe.
Fig. 3 is the utility model volume formula probe.
The utility model is made up of the set of circuits in hand-held shell 3 and probe 1 and the shell.Described set of circuits comprises a pyroelectric detector 4 that is positioned at the same axis of probe place, a prime amplifier 6 that amplifies detector output signal, one with amplified signal carry out the analog-digital converter circuit 7 of ambient temperature compensation and scale transformation, 8, one final LCD numerals that realize that the body temperature numeral shows of a lcd driver show 9.It is characterized in that the inner chamber of popping one's head in is the rotation bodily form, on the through hole inner rotary body axle of hand-held housing junction, the infrared crystal lens are housed, crystalline lens 5 optical axis are over against pyroelectric detector 4, at lens 5 and heuristic an interlock shutter 2 by button control is arranged between the device 4.
Probe described in the utility model can be a bowl formula shape, and its inside surface plated film so forms volume formula clinical thermometer, can also be the ear type shape, can insert thermometric in the duct, forms ear clinical thermometer.
The utility model is surveyed the radiation that human body sends with photodetector, and is measured human body temperature according to the human infrared radiation principle.Existing thermometer is compared, and needn't contact human body surface entirely, and measuring process is quick, only needs 1-2 second, and numeral shows, digital latch, and convenient reading is directly perceived, according to the measurand difference, is designed to volume formula probe on the structure, is suitable for the infant, and ear formula probe is suitable for the adult.
Claims (3)
1, a kind of Infrared Radiation Human-Body Thermometer is that described circuit comprises because the set of circuits of holding in formula shell (3) and probe (1) and the shell is formed: one is positioned at the outer pyroelectric detector (4) of probe bore axis extended line.A prime amplifier (6) that amplifies detector signal, an analog-digital converter circuit (7) of this signal being done ambient temperature compensation and scale transformation, a lcd driver (8), and LCD digital indicator (9) that shows temperature data, it is characterized in that, described probe (1), has rotation bodily form inner chamber, with shell (3) connection place through hole is arranged, axially bored line and inner chamber revolve axis, and point-blank, infrared crystal lens (5) are equipped with in the through hole, lens (5) optical axis is provided with the interlock shutter (2) of button control to pyroelectric detector (4) between the two.
2, Infrared Radiation Human-Body Thermometer as claimed in claim 1 is characterized in that described probe is bowl-shape mechanism, and its inner chamber is circular.
