Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a human body fixture used for fingertip measurement type pulse wave measurement.

Conventional technology Conventionally, this type of pulse wave measurement has generally been carried out by inserting only the fingertip into the detection device 12 as shown in FIG. In order to maintain the same level of control, the subject was placed supine on the bed and the arms were stretched naturally to the side of the body during measurements.

Problems to be Solved by the Invention In such a conventional configuration, the person to be measured has to take the trouble to lie down on the bed, and even in that state, the arms are not fixed. Measurement errors were unavoidable. In particular, in the case of fingertip pulse waves, the sensor output is extremely weak at around 1 mV.
A slight movement of the arm tends to directly affect the measured data, and can easily become a disturbance factor in the form of disturbances in the output waveform or fluctuations in the baseline. For these reasons, pulse wave measurements cannot be performed at medical institutions such as hospitals without a doctor's instructions, and even though the pulse wave itself contains an extremely large amount of useful physical information, it cannot be measured at home. In addition to this, the current situation is that even regular health checkups do not take measurements.

The present invention is intended to solve these problems, and aims to enable anyone to easily and accurately measure pulse waves without having to take a specific posture such as lying supine on a ped. It is something to do.

Means for Solving the Problem In order to solve this problem, the present invention provides an opposite telescopic connection in which a recess is provided in the shape of the material part to support the material part of the human body.

Function: With this configuration, the person being measured adjusts the positional relationship between the elbow rest and the arm rest according to the length of his or her arm, fits his or her arm into the recess, and inserts his or her finger into the pulse wave detection section. This allows the arm to be placed in a stable measurement state naturally, allowing the person to be measured to easily fix the arm anytime, anywhere, stabilizing the blood flow at the fingertips, and allowing anyone to take measurements. This makes it possible to measure a stable pulse wave waveform even when the pulse waveform is measured.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 and 2. In the figure, reference numeral 1 denotes an arm rest for supporting a member of the human body, and a recess 2 in the member is formed to match the shape of the member. 3 is an arm rest that is slidably fitted into the arm rest 1;
is a forearm recess formed on this arm rest 3. 5
2 is a pulse wave detecting section provided on the arm rest 3 at a position corresponding to the middle finger, and a hole 6 that matches the shape of the finger is bored inside, and a light emitting section 7 and a light receiving section 8 are located at the tip of the finger. Built-in.

Reference numeral 9 indicates a column supporting the arm rest 1, 10 indicates a support base, and 11 indicates the state of the arm when in use.

The operation of the above configuration will be explained. When measuring a pulse wave, the person to be measured aligns his/her elbow with the recess 2 of the material part of the elbow rest 1, inserts the middle finger into the hole 6 provided in the pulse wave detection part 5, and measures the distance from the material part to the fingertip. Adjust the arm rest 3 by moving it back and forth as shown by the arrow in Figure 1 so that the length matches your arm.

In this state, the arm of the person to be measured is supported by being accommodated in the member recess 2 and the forearm recess 4, resulting in a stable state. When measuring fingertip pulse waves, the body movement that is considered to be the largest disturbance is mainly caused by the area beyond the elbow; if the condition is fixed as shown in Figure 2, the disturbance due to body movement can be almost ignored. becomes. In this state, the light emitted from the light emitting unit 7 passes through the fingertip of the person to be measured, and the transmitted light is detected by the light receiving unit 8, and the amount of light transmitted changes depending on the increase or decrease in the amount of blood at the fingertip. This enables stable and accurate pulse wave detection.

Effects of the Invention As described above, according to the present invention, anyone can easily fix the arm, so anyone can easily measure pulse waves, which was conventionally considered impossible without the help of medical personnel. At the same time, stable and highly accurate measurement results can be obtained. Furthermore, as there is no need to take measurements lying supine on a bed as in the past, there is less psychological burden on the person being measured, and the disadvantages of pulse wave measurement, in which the psychological state is easily reflected in the measured values, can be overcome. In addition, since pulse wave measurement can be performed relatively easily, it is not easy to use in ordinary medical examinations or health checks in ordinary homes, and is extremely practical.
