Abstract

The utility model discloses an ear thermometer with an optical fiber conductor. The probe of the ear thermometer mainly comprises a shell, an optical fiber conductor, a heat sensor and a circuit board. When the ear thermometer is used to measure the ear temperature, the heat radiation of the temperature in an ear canal is accumulated through a convex surface at one end of the optical fiber conductor and is transmitted by the optical fiber conductor. When the heat radiation reaches the other end of the optical fiber conductor, the heat radiation is evenly scattered to the heat sensor through the convex surface at the end, so the temperature in the ear canal is measured by using the heat sensor. The probe of the ear thermometer can be separated from the ear thermometer and can be solely put in the ear canal. The temperature measured in the ear canal is transmitted to the ear thermometer through a wireless transmission device arranged in the probe so as to continuously monitor the ear temperature.

Technical field

This utility model relates to a kind of ear thermometer of tool fiber optic conduction, refers to a kind of structure in order to take temperature especially.

Background technology

At present, the variation of body temperature is one of the alert news of numerous disease normally, therefore, the measurement of body temperature is one of very important work with following the trail of for sufferer, take temperature was with traditional contact mercurial thermometer in the past, but its induction speed is slow and problem on the health arranged, so that develop general now employed electronic type thermometer, as Fig. 1 and shown in Figure 2, probe portion 1 for general institute use infra-red thermometer, be provided with the waveguide 11 of a hollow round tubular in this probe portion 1, and waveguide 11 inwalls are a smooth material that can be reflective, mainly put into human body external auditory meatus by probe portion 1, and the heat radiation of the interior temperature of auditory meatus is passed to the thermal sensor 12 of an end via the interreflection of waveguide 11 inwalls, make thermal sensor 12 receive the interior temperature of auditory meatus, and with the temperature and the temperature difference that receives in the auditory meatus of thermal sensor 12 itself, and then learn the variations in temperature of human body, and temperature data reached circuit board 13, show human body temperature with exterior display device, yet, probe portion 1 is when putting into auditory meatus, probe portion 1 can contact with auditory meatus unavoidably, because the temperature of waveguide 11 itself is lower than the temperature in the auditory meatus usually, therefore after the temperature of meatus acusticus internus is passed to thermal sensor 12 via waveguide 11, can make the temperature of waveguide 11 itself that to a certain degree rising is arranged, cause thermal sensor 12 can detect the temperature section that waveguide 11 rises simultaneously, make the body temperature of measurement produce error, and, waveguide 11 is to transmit in the mode of inwall reflective thermal radiation, therefore waveguide 11 must be the straight tube-like kenel in design, so probe portion 1 must cooperate waveguide 11 in design.

The utility model content

Main purpose of the present utility model is: probe portion consists predominantly of a housing, a conductor fiber, a thermal sensor and a circuit board, wherein the both ends of the surface of conductor fiber respectively are made as a convex body face, when conductor fiber receives the heat radiation of auditory meatus, assemble heat radiation on every side by the convex body face of conductor fiber one end and enter conductor fiber, and via the radiation of conductor fiber transferred heat, when heat radiation arrives the other end of conductor fiber, by the even scattering heat radiation of the convex body face of this end, make thermal sensor receive heat radiation fully, reach the purpose of effective measurement ear temperature whereby.

Another purpose of the present utility model is: the housing of probe portion is designed to a mobilizable structure, therefore can reach and can adjust the purpose that conductor fiber stretches out the length of housing according to demand by movable this housing.

Another purpose of the present utility model is: conductor fiber itself has can be around the characteristic of volume, and the clad that conductor fiber coated is made by the reelability material, therefore, after conductor fiber stretches out housing, can bend the angle of this conductor fiber according to the demand of measuring, whereby, conductor fiber can be inserted auditory meatus with different angles according to demand.

Another purpose of the present utility model is: circuit board is arranged between the thermal sensor pin, and the two sides of circuit board all is coated with a heat dissipating layer, except thermal sensor and circuit board are reached the radiating effect, also can prevent to cause error because of accumulative heat energy causes the induced temperature of thermal sensor, reaching with this increases the purpose of measuring accuracy rate.

A purpose more of the present utility model is: wherein probe portion can be separated with ear thermometer, probe portion can be placed in separately in the auditory meatus, and by set radio transmitting device in the probe portion, the temperature of being felt in picking up the ears can be transferred to ear thermometer, with monitoring temperature continuously.

The specific embodiment

For achieving the above object and effect, technological means that this utility model adopted and structure will illustrate in detail that with regard to preferred embodiment of the present utility model its feature and function are as follows according to accompanying drawing, so that understanding fully.

See also Fig. 3 and shown in Figure 4, be cutaway view of the present utility model and partial schematic diagram, by being clear that among the figure, the probe portion 2 of ear thermometer consists predominantly of a housing 3, one conductor fiber 4, one can be thermoelectric pile, the thermal sensor 5 and a circuit board 6 of burnt hot assembly or critesistor, wherein conductor fiber 4, thermal sensor 5 all is arranged in the accommodation space 30 of housing 3 with circuit board 6, the two ends of conductor fiber 4 are designed to convex body face 41, the periphery also coats these conductor fibers 4 with the clad 42 of a light tight reelability material, and a termination of conductor fiber 4 places thermal sensor 5, and thermal sensor 5 also connects a circuit board 6;

In addition, thermal sensor 5 has four pins, 6 of circuit boards are arranged between four pins, just the two sides of circuit board 6 distinctly is equipped with two pins, therefore and the two sides of circuit board 6 all is coated with a heat dissipating layer 61, is arranged at the heat dissipating layer 61 that is coated with the two sides between four pins by circuit board 6, makes thermal sensor 5 and the circuit board 6 can both efficiently radiates heat, and the housing 3 of probe portion 2 is a mobilizable structure, makes conductor fiber 4 can adjust the length of exposing outside the housing 3.
