Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a simple portable autoarterial heart rate monitor that uses electrical energy from body heat or natural light.

This device uses a conversion power generation element that generates electricity from the emission of artificial light, eliminating the need to replace dry batteries.

"Prior art and its problems" There are many simple portable arterial heart rate monitors available in the prior art, but all of them use small dry batteries for electrical energy, requiring periodic replacement of the batteries. However, there is a risk that the battery will run out when used in an emergency or for a long period of time, which is not desirable. Furthermore, f%L battery replacement cannot be done without the help of an electrical specialist.

There are various problems in use.

"Apex and Objectives of the Invention" The present invention was made against the background of the above-mentioned problems of the prior art, and its purpose is to convert electrical energy into the heat of the human body, natural light, artificial light, etc. It is based on a conversion power generation element that generates electricity from the power generated by light, eliminating the need to replace dry batteries.

"Means for Solving the Problems" The gist of the present invention is that a thermoelectric conversion power generation element that converts human body heat into electrical energy or a photoelectric conversion power generation element that converts light into electrical energy is used as a drive source. It is an autoarterial pulse meter. Furthermore, the arterial heart rate meter is capable of switching between a thermoelectric or photoelectric conversion power generating element serving as a driving source using a switching member of a switch. This is an autoarterial pulse meter in which a thermoelectric conversion power generation element is attached to the main body in close proximity to a pulse detection sensor.

Further, the main body of the present invention is an autoarterial heart rate monitor equipped with a reset switch for resetting at least a digital display and an arithmetic circuit.

"Example" Hereinafter, one embodiment of the autoarterial pulse meter of the present invention will be described with reference to the drawings.

In FIG. 1, a pulse detection sensor S (sound absorption, vibration absorption microphone, pressure sensor, etc.) detects the pulse of blood passing through a blood vessel in a wrist 1a of a hand 1, for example, and a pulse detection sensor S (sound absorption, vibration absorption microphone, pressure sensor, etc.) that senses the body temperature of the wrist 1a, and detects the body temperature of the wrist 1a. Thermoelectric conversion power generation elements that convert into electrical energy (thermocouples, thermoelectron generating elements...)
This power generation element G is equipped with a converter 2.G which adjusts the voltage to a constant voltage regardless of the temperature of the heating element. The voltage E is adjusted by VL to the voltage E necessary to operate each circuit AMP1 to CPU and D. The urine pulse detection sensor S may be of a type that detects pulse vibration using a microphone or a type that detects fluctuations in pulse pressure, or other appropriate means. The voltage amplifier AMPI amplifies the minute detection signal from the pulse sensor S and outputs it as a digital or analog signal sufficient to operate the arithmetic circuit CPU. % operation starts the built-in clock circuit (not shown),
The number of pulse pulses to the arithmetic circuit CPU within a predetermined period of time (usually about several seconds) is counted, converted to the number of pulses per minute, and displayed on a digital display. The above-mentioned autoarterial pulse meter 10 includes:
Of course, the source of electrical energy may be found in the solar cell SG. Furthermore, as shown in FIG. 3, when the thermoelectric conversion power generation cord G and the solar cell SG are arranged side by side, a switch Sw for both is provided, so that the type can be used for both purposes. In addition to the digital display, it may also be used in connection with an oscillograph OG for measuring 1gl of pulse waveforms.

Next, referring to FIG. 2, the external appearance of the autoarterial pulse meter 10 of the present invention will be described. FIG. 2(a) shows a wrist 1a equipped with a thermoelectric conversion power generation element G and a pulse detection sensor S at the tip of the main body 11.
By bringing both G and S into contact with each other, pulse detection and electrical energy are operated simultaneously. Reset button RB in the center of main body L1.

Equipped with a digital display on the head. In FIG. 2(b), a changeover switch SW and a solar cell SG are provided in the center of the main body 11 so that they can be used selectively. FIG. 2(c) shows a pulse detection sensor S and a reset button RT3. Equipped with solar battery SG and digital display.

``Effect J'' With the above configuration, the pulse of the human body can be easily used anywhere without replacing the battery, and has the feature of having a great practical effect.It is of course possible to modify the design other than the above embodiment.
