Abstract

PURPOSE:To accurately detect the pulse without imparting a sense of oppression and a feeling of physical disorder and generating the shift of a band at the time of bodily motion by loosely inserting a flat cylindrical electrode composed of a conductive elastomer in a stretchable mounting band and fastening one end of the electrode to the mounting band by a fastener also used as a terminal. CONSTITUTION:A plurality of adjusting hook parts 2 are provided to a mounting band 1 rich in stretchability composed of rubber so as to fit said band to the chest circumference of an examinee and flat cylindrical electrodes 3, 3... rich in flexibility composed of a conductive elastomer are loosely pass through the mounting band 1 and one ends thereof are fastened to the mounting band 1 by fasteners 4, 5... also used as terminals. When this band is mounted to the chest, the electrodes 3, 3... are held to the chest in a close contact state by proper elastic force and not shifted by the motion of the examinee. Therefore, the pulse can be detected accurately. A sense of oppression and a feeling of physical disorder are not also felt by the stretchability of the whole of the mounting band and the mounting fitted to the chest of the examinee.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to pulse detection, and particularly to a pulse detection band that is applied to the chest or the like during pulse measurement to detect the pulse.

(b) Prior art In recent years, methods of measuring the amount of exercise and physical strength using pulse rate as a guide have become popular. For example, as a representative example, as in Japanese Patent Publication No. 60-1.16325, a part of the sensor that detects the cardiac potential is fixed to the chest, the weak cardiac potential is detected and amplified, and the display is displayed using a magnetic field. I have something to send. In this case, since the person being measured is exercising, it is important that part of the sensor is firmly attached to the chest. Conventionally, in order to attach a portion of this sensor, a plurality of electrodes 11. ．． 11. on the entire surface with adhesive, and this fixing bell h1. As shown in FIG. 5, elastic attachment bands 1.2 were attached to both ends of the test subject, and the attachment bands 12 were pulled and adjusted to fit the subject's chest.

And each electrode 1.1. ．． 1.1 Terminal 1 in one place
3.13... are attached, and the cardiac potential detected by the electrodes is input to the transmitting device 14. Said terminal], 3.
1.3... is the electrode 11. ．． 11..., and the mounting grooves 1.5, 1.5 on the transmitting device 14 side.
- Convex portion 13a at the tip.

13a... are fitted in a hook shape and are electrically and mechanically coupled. Furthermore, although not shown, the detection signal from the transmitting device 14 is sent to a receiving device worn on the wrist, where it is analyzed and the state of heartbeat and pulse can be determined.

(c) Problems to be Solved by the Invention However, if the elastic force of this attachment band is weak, the electrodes will shift during exercise, making it impossible to detect electrocardiographic signals having a weak potential of several mV or less. Also, if you pull too hard, it will put pressure on your chest, making it difficult to breathe and make it difficult to exercise. Furthermore, since it is attached to a fixation bell I, when this electrode is applied to the chest, there may be a gap between the human body and the electrode due to differences in body shape, which may make it impossible to detect cardiac potential signals. Sometimes it was enough.

The present invention has been developed in view of the above-mentioned problems.It is in close contact with the human body even during exercise and can accurately detect cardiac potentials, does not change the wearing condition due to differences in body position, and does not cause pressure sensations. An object of the present invention is to provide an improved pulse detection band on the pulse side that does not cause any discomfort when worn.

(d) Means for Solving the Problems The pulse-shaped pulse detection band according to the present invention is attached to an elastic attachment band that is wrapped around the chest of a subject during pulse measurement.
A plurality of flat cylindrical electrodes made of conductive elastomer are loosely inserted into each electrode, and one end of each electrode is fixed to the mounting pan 1 with a fastener that also serves as a terminal.

(E) Function: The elastic attachment band allows the electrodes to be pressed against the chest with a moderate amount of force, so the electrodes will not shift or cause a strong pressure sensation during exercise. In particular, since only one end of the electrode is fixed and most of the electrode is free from the attachment hand, even if the attachment band expands and contracts due to exercise, the electrode does not move in the same way and can maintain good contact with the human body. Does not reduce measurement accuracy. Furthermore, since the electrodes are made of elastomer and have flexibility, they can be attached to the human body without any gaps and can accurately capture cardiac potential signals.

(f) Example Embodiments of the present invention will be described below based on the drawings.

1 is a highly elastic attachment band such as rubber, which is adjusted so that it is wrapped around the chest of the subject whose pulse is to be measured and attached with an appropriate amount of force, and is attached to the hook part 2 at the front of the subject's chest. It can be hung for easy installation. Adjustment can be made by providing a plurality of hook parts 2 to match the chest circumference of the subject. 3, 3, this mounting band 1 is loosely passed inside (see Fig. 2), and one end thereof is fixed with a stopper 4, 4, etc. which also serves as a terminal, and is attached to the mounting band 1. The electrode is made of conductive elastomer and is highly flexible, and has a flat cylindrical shape. This electrode 3
, 3 . . . can be made into a flat cylindrical shape by integral molding, but instead of relying on integral molding, they may be made into the same shape by bonding the sheets 1 to 3 together.

That is, the attachment band 1 serves as a support for the electrodes 3, 3, and also serves as an attachment member for holding the electrodes 3, 3 against the chest, thus having two functions. In this way, by forming a pulse detection band in which the conductive elastomer electrodes 3, 3 are attached to the elastic attachment band 1, when this band is worn on the chest, the electrodes 3, 3 will be attached to the chest with a moderate elastic force. It is maintained in close contact with the subject and will not shift due to the subject's movements. Therefore, accurate pulse detection can be performed. In addition, the entire attachment band expands and contracts so that it can be attached with appropriate elasticity to suit the subject's chest, so the subject can comfortably exercise without feeling pressured or uncomfortable.

The electrodes themselves are highly flexible, allowing them to be attached tightly to the subject's chest without leaving any gaps, allowing them to accurately capture cardiac potential signals and accurately measure pulse.

(G) Effects of the Invention As described above, the present invention provides a flat cylindrical electrode made of conductive excimer that is loosely inserted into an elastic mounting band, and one end of which is attached to a stop that also serves as a terminal. When the elastic mounting band is wrapped around the subject's chest and attached, the appropriate elasticity of the mounting band prevents the electrode from feeling any pressure or discomfort on the chest. , it is pressed against me and does not move even when I exercise,
Accurate pulse detection is possible. Conventionally, electrodes were attached to a fixed band, which had the disadvantage that the electrodes would peel off due to frictional resistance with the human body during exercise, rendering them useless.However, in the present invention, the electrodes Since the elastic mounting band is attached in a free state, such a phenomenon does not occur and it can withstand long-term use.

In addition, by attaching the electrode to a flexible mounting band, the electrode can be attached to the human body without any gaps, regardless of the subject's body position (chest), and the pulse signal can be reliably captured, resulting in excellent measurement accuracy. This is the pulse detection pan 1- of the pulse meter.
