Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to the improvement of a pine surgery machine, and more specifically, it is possible to freely adjust the acupressure intensity and the acupressure pattern according to the individual needs of the patient. Regarding Nishida hydraulic type pine surge machine.

(Prior Art) Conventionally, as a pine massage machine that applies acupressure to the back of a patient, for example, as disclosed in Japanese Patent Application Laid-Open No. 50-4892, a rear end of an acupressure frame that protrudes from the back of a chair is used. A device is known in which acupressure is applied to the back of a patient by protruding and retracting an acupressure frame that comes into contact with a cam rotated by a motor.

(Problem to be Solved by the Invention) By the way, the shiatsu practitioner's shiatsu pattern, which is said to produce a high pine surge effect, is as shown in FIG. 1i of descending pattern! This acupressure pattern is applied to the patient's affected area for a long time.
It is characterized by its change, which is why it has a very high pine surge effect at 1q. Therefore, it is desirable for the pine massage machine to be able to freely vary the intensity of acupressure and its holding time according to the patient's preference and the affected area, as this will allow for a higher pine surge effect.

However, in the above-mentioned conventional device, the amount of displacement of the acupressure stick is determined according to the cam shape. The strength of the acupressure applied to the patient's back may be larger and feel more painful after one treatment, and the strength and load of the acupressure may vary depending on the individual of the patient, how they put their weight on the acupressure stick, failure to escape, etc. J: It is very easy to use, and it is possible to obtain acupressure intensity according to the patient's preference. g: t: Similarly, due to the constant displacement of the acupressure stick, it is difficult to obtain acupressure intensity that matches the patient's preference for each affected area, and a high pine surge effect cannot be expected.

-31 The present invention has been made in view of the above points, and its first purpose is to hydraulically perform acupressure and other operations in a pine surgical machine, and to control the hydraulic pressure by IP, so that medical treatment can be performed. To improve the effect of pine surge by enabling acupressure or the like to be applied with acupressure intensity that is appropriate for the person's preference and the affected area.

A second object of the present invention is to perform the above-mentioned hydraulic pressure load control at -F below or below the position of the means (finger section) for pressurizing the patient's back. [When moving to the right, if the finger presses the back of the recipient and moves up and down or left and right, the patient will feel discomfort and pain, and the finger will move. Later, we focused on the fact that it was not possible to start acupressure on the patient's back from an acupressure intensity of almost zero, and the pine surge effect decreased, and so When moving to the right, first move the fingers back to a position that does not pressurize the patient's back,
After that, by starting to move the finger up and down or left and right, it eliminates the discomfort and pain caused to the patient when changing the position of the finger, and also reduces the finger F at the zero value.
[The aim is to use the strength to create acupressure properties and to exert the above-mentioned high Ma Sonage effect on the right column.
