Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to the configuration of a device for measuring body temperature and pulsation rate of an animal.

[0002]

[Prior art]

 There are many documents regarding non-contact infrared sensors that are used to measure body temperature. (For example, CLINICAL PEDIATRICS magazine separate volume FEVER AND TYMPANIC THE- RMOMETRY: Issued in April 1991.) There are many types such as those that use a let-type microphone or a piez-elect element. On the other hand, as an optical measurement, using a light emitting diode with a relatively short wavelength and its light receiver, the flow of blood, which is a pulsating flow, is sensed as an optical change amount by a transmission or reflection type sensing method. Things are also well known. Further, it can be sensed by a pressure sensitive film or a pressure sensor. However, heretofore, there has not been found a portable type in which such a temperature sensor and a pulsation rate sensor are extremely effective in use. Therefore, it has been impossible to obtain important information from patients simultaneously and easily.

[0003]

[Problems to be solved by the device]

 The present invention, which is provided to solve these problems, aims to simultaneously measure the body temperature and the pulsation rate.

[0004]

[Means for Solving the Problems]

The basic configuration of the present invention is as shown in the diagram as a typical one in FIG. S (non-contact type infrared sensor [for example, TS-15 or TS-16 type manufactured by Nippon Ceramic Co., Ltd.]) and pulsation sensor P.S. S (for example, an electret microphone manufactured by many makers or PVF ₂ manufactured by Kureha Chemical Industry Co., Ltd., and a semiconductor pressure sensor) is used together, and a mechanism CPU that processes the signals obtained from each is used. A mechanism for switching the functions such as body temperature, pulse rate, resetting, power-off, etc. automatically or semi-automatically based on the signal obtained therefrom. W. Next, a mechanism for visually displaying the signal, or transmitting it to the human senses by a synthesized voice in combination or alone as needed. It is characterized by having P and a power supply for operating those functions. It should be noted that the mechanical structure for temperature measurement, for example, the shutter mechanism used as the most advanced technique for measuring the surface temperature of the eardrum in a non-contact manner, can be used as it is. I will omit it because it does not need to be done.

[0005]

[Action]

 Due to the simultaneous measurement of body temperature and pulse rate, which are the two important information for judging the health condition of animals, with a single device, it is possible to reach the goal in one tenth of the conventional time. is there.

[0006]

【Example】

In order to measure the body temperature, first, the non-contact type infrared sensor 30 is arranged so as to receive the heat radiation from the surface of the eardrum 31 of the measured part as shown in FIG. 3, and the shutter 32 provided in the optical path is set for a predetermined time. Open for about 2 seconds or more, and arrange with the signal processing mechanism CPU including the high energy level received during that time and the signal level from the surrounding temperature compensation sensor (not shown in the drawing). On the other hand, as the pulsation sensor, the case of using the pressure sensor among the above-mentioned optical sensor, voice sensor and pressure sensor will be described. The method of treating as a signal converted into an electric quantity should be considered the same. Here, a covering cover 33 is attached to part or all of the periphery of the attachment 3 to be inserted into the ear canal for temperature measurement by using a pressure sensitive substance such as PVF ₂ . An electrode is provided on this pressure-sensitive membrane, and when the attachment is inserted into the ear canal, the pressure displacement is measured according to the pulsation rate generated between the attachment and the inner peripheral surface of the ear canal. As shown in the pattern of this pressure displacement in FIG. 2, a normal pulsating wave type P ₀ is generated after a noise signal PN generated when the attachment 3 is inserted into the ear canal is generated. The next signal P ₁ that closely resembles this signal waveform, or P ₂ or more signals as needed to improve the accuracy, is taken in as historical data (HISTORICAL DATA), and the waveform resemblance and its tip to tip Based on the time of the part (PEAK TO PEAK) ΔT ₁ ≈ ΔT ₂ ≈ ΔT ₃ , the average value ΔT between peaks of the pulsating wave type is calculated, and the pulse number is measured with the pulsation rate P = 60 / ΔT. The signal is sent to the next signal switching mechanism S. W., and a display or voice signal converter D.W. Operate P. In the above embodiment, the case where the infrared sensor and the pressure sensitive film using the piezoelectricity of PVF ₂ are applied as a pulsation sensor is described. Therefore, in principle, other sensors may be used in combination. Even when an optical sensor or a semiconductor pressure sensor is used with the configuration described in the invention, it can be sufficiently completed by the conventional technical means.
