DESCRIPTION:

BRIEF SUMMARY
BACKGROUND OF THE INVENTION

1. Technical Field
The present invention relates to a touch detecting device for detecting the grip state when an individual grips an object, a touch notifying device, an information inputting device that employs the touch detecting device, a touch replicating device, a touch transmission system, a pulse diagnostic device, a pulse diagnostic training device, and a pulse diagnostic information transmission system.
2. Background of the Invention
In Chinese medicine, the physician performs a pulse diagnosis by applying pressure on the skin over the patient's radius artery with his fingers. A diagnosis of the patient's physiological state is then made based on the pulse sensed by the physician through his fingers. The physician registers the pulse, referred to as sunko, in the radius artery which is located on the inner side of the wrist. The sunko pulse can be detected at three sites--upper, middle and lower, i.e., sunn, kann, and shaku sites, at the periphery. In contrast, an orally conveyed medical learning known as Ayurveda has long been known in India. As in the case of pulse diagnosis in Chinese medicine, in Ayurveda, the physician applies pressure with his second through fourth fingers on the skin over the radius artery in the patient's arm to take the pulse
A technique for regularly and quantitatively performing a pulse diagnosis is disclosed in JPA No.6-197873, in which a rubber glove in which a plurality of linear distortion gauges have been affixed to sites in contact with the second through fourth finger pads is placed on the hand, and the pulse wave is detected by applying pressure on the sunko with the tips of the three fingers. In this case, the physician registers the pulse of the radius artery via the distortion gauges and the rubber glove.
In addition, Japanese Patent Application, Second Publication No. Sho57-52054 discloses a technique for detecting the pulse wave by attaching a microphone formed of a piezoelement to the three sunn, kann, and shaku sites. In this method of measurement, the pulse is directly measured without employing sensation from a person's fingers.
Normal, smooth and violent waves may be cited as representative pulse waveforms. A normal wave is characteristic of a "normal" or healthy subject, and is relaxed, having a constant rhythm without disruption. The smooth wave, on the other hand, is caused by an abnormality in the flow of blood in which the movement of the pulse becomes extremely smooth due to a mammary tumor, liver or kidney ailment, respiratory ailment, stomach or intestinal ailment, inflammation, or some other illness. On the other hand, a violent wave is caused by tension or aging of the walls of the blood vessels, and is seen in diseases such as liver and gall ailments, skin ailments, high blood pressure, and pain ailments. It is believed that the elasticity of the walls of the blood vessels decreases, so that the effect of the pulse movement of the pumped blood is not readily expressed, causing this phenomenon. The waveform of a violent wave rises violently, but does not fall off immediately, remaining at a high pressure state for a fixed period of time. In terms of the sensation registered by the fingers, a violent pulse wave feels like a straight tense and long pulse.
Pressure is applied on the radius artery during a pulse diagnosis. However, the state of the pulse registered by the fingertips will vary depending on how much pressure is applied As shown in FIG. 15, the extent of pressure P at the fingertip may be qualified as light, moderate or heavy, while the finger sensation h, which shows the strength of the pulse registered by the fingertips, may be qualified as large, medium and small. In this example, a graph in which finger sensation h is plotted on the vertical axis, and pressure P is plotted on the horizontal axis is referred to as a pressure-finger sensation trend diagram.
A typical pressure-finger sensation trend diagram is shown in FIG. 16. FIG. 16(a) shows the pulse when finger sensation h is obtained at a moderat
