Description

[Detailed description of the invention] Industrial application field The present invention is intended to provide hypnotic treatment to patients with psychogenic diseases by placing the patient in a hypnotic state, that is, an altered state of consciousness (hereinafter referred to as "altered state of consciousness").
This is a device to be introduced into the ASC.

Conventional technology As a conventional technology, there is Utility Model Application Publication No. 58-43456.
The technology disclosed in this publication is such that a mechanism for raising and lowering a tilting operation unit consisting of a pedestal and a backrest with respect to an underframe is attached to the output shaft of a speed reducer that is linked to an electric motor. The fixed crank arm rotates the support shaft at the rear end of the pedestal.

The problem that the invention attempts to solve: The hypnotist (hereinafter referred to as the patient) placed on a chair.
In conventional chairs, which rotate within a predetermined angle range to create tension and relaxation, the pivot point is not approximately at the center of gravity of the chair, so in order to rotate the chair, large-capacity motors, speed reducers, etc. are required. It had to be equipped with a power source. For this reason, the inertia of the driving source is large, making it difficult to alternately and continuously move the chair parts, and furthermore, the noise and vibration of the driving source become large as the size of the driving source increases.

Means to Solve the Problems This invention is a new device that eliminates the drawbacks of the conventional devices, and has a braking system that can rapidly and efficiently back down and stand up continuously, and that produces extremely low operating noise during back down and standing up operations.

It is pivotally supported by a lever support 36 erected from 7.

FIG. 4 shows yet another embodiment of the chair.

Function The patient to be treated with hypnosis is made to sit on the chair part 1 in a sitting position, and the chair part 1 is rapidly rotated backwards around the side plate pivot 6 to place the patient in a reclined position, and the patient is placed in a hyperextended position. The chair part 1 is rapidly rotated forward to return to the standing position and the patient is placed in a sitting position. Furthermore, the chair portion 1 with the patient in a sitting position is gently reciprocated back and forth. In this way, chair part 1
The patient is repeatedly
Introduced to ASC.

Next, the operation of the device will be described.

A support 8 holds a side plate pivot 6 of a side plate 5, and balances the weight of the front half and the back half of the chair part 1 on which the patient is sitting.

A connecting mechanism part 1 whose one end is connected to a seat part pivot part 9 of a chair part 1 which is rotatable around a side plate pivot part 6.
3, the seat pivot portion 9 is pushed up or pulled down to its original position. The other end of the coupling mechanism section 13 is pushed up or down by the rod 12 of the oil cylinder 10.

When pressure oil is rapidly injected from the hydraulic mechanism section 11 into the main chamber 26 of the oil cylinder 10, the rod 12 advances and oil flows out from the forward chamber 28, and the connecting mechanism section 13
The chair part 1 is tilted back through the . Conversely, when pressure oil is rapidly injected into the front chamber 28 of the oil cylinder 10, the oil flows out from the front chamber 26 and the rod 1 advances.
2 retreats and returns the chair section 1 to its original position.

To explain this in more detail, when the rod 12 advances, the lever 17 of the coupling mechanism section 13 rotates around the lever pivot portion 14. In FIG. 1, the lever 17 moves counterclockwise. The rotating lever 17 is attached to a rod 19 that is hooked via two springs 18 inserted through the lever 17.
is pressed, and the rod 19 transmits this pressing force to the seat pivot portion 9, pushing the seat portion 2 upward and tilting the chair portion 1 backward.

When lever 17 is pushed by rod 12 and rotates,
When the lever 17 tilts the chair part 1 slightly backward and the center of gravity of the chair part 1 moves rearward from the side plate pivot 6, the lever 17 begins to compress the brake spring 25.

The compressed braking spring 25 absorbs the inertia force caused by the backward tilting of the chair part 1, smoothes the advance of the rod 12, and as a result, the chair part 1 is smoothly tilted backwards. That is, due to the speed of the rod 12 pushing the chair part 1, the chair part 1 is moved to the rod 1 via the connecting mechanism part 13.
The braking spring 25 is connected to the chair part 1 so that the hydraulic pressure in the base chamber 26 does not become negative pressure due to the faster pulling speed of the brake spring 25.
The movement of the oil cylinder 10 is suppressed and the operation of the oil cylinder 10 is made smooth. At this time, if the braking spring 25 were not present, the rod 12 would be rapidly pulled in the advancing direction, causing the former chamber 26 to
Injection and replenishment of pressure oil cannot keep up with the expanded volume of the tank, resulting in negative pressure being applied to the oil. When negative pressure is applied to the oil, bubbles are generated in the oil and the operation of the oil cylinder 10 becomes irregular.

When rod 12 withdraws, lever 17 is pulled in,
Pull down the seat pivot portion 9 via the pole 19 and the chair portion 1
from the reclined position to the standing position. Rod 12
When the rod 12 moves back and forth, the speed of the rod 12 moving back and forth is suppressed by a throttle valve 27 provided in the outflow oil pipe of the source chamber 26. If the speed at which the chair section 1 that returns to its original position pushes the rod 12 through the connecting mechanism section 13 is faster than the speed at which the rod 12 is moved by the oil injected into the front chamber 28, the piston 40 rapidly moves downward, and the oil pressure in the forward chamber 28 attempts to become negative pressure. However, the main chamber 26 is filled with oil whose outflow is suppressed by the throttle valve 27, and this oil prevents the piston 40 from flowing out.
is restrained from moving downward rapidly, and the volume of the front chamber 28 is occupied by the volume of the rod 12.
Since the volume of the front chamber 28 is smaller than that of the main chamber 26, the pressure oil can be sufficiently replenished into the front chamber 28, so that the oil pressure in the front chamber 28 does not become a negative pressure. The operation of the rod 12 is controlled by pressure oil from the hydraulic mechanism section 11, but the inertial force of the chair section 1 generated at the operating end of the rod 12 is absorbed by the spring 18.

The control valve 31 is operated by a manual switch 34 of an operation box 37 and a signal from a signal recording/reproducing device 35.

In addition, in this device, the upper half of the backrest portion 3 is bent backward so that a patient in a hyperextended posture in a backward position can be easily supported.

Next, we will discuss how the movement of the device affects the patient's mind and body.

When the chair portion 1 is changed from the standing position to the reclined position, the patient shifts from a sitting posture to a hyperextended posture.
When the patient is in a sitting position, the patient's mind and body are relaxed, and when the patient is in a hyperextended position, that is, in a supine position with a slight bend toward the back from the horizontal position, the patient feels tension in the mind and body. In addition, the patient who is sitting on the chair part 1 which is rocked like a cradle feels relaxed in mind and body.

An operation of stopping the chair part 1 in the standing position or continuously rotating the chair part 1 alternately between backward rotation at a slight angle and forward rotation in the direction of the original position;
The action of rapidly tilting the chair 1 backward to bring it to the reclined position, and then returning the chair 1 from the reclined position to its original upright position are repeated, giving relaxation and tension to the patient and increasing the depth of ASC. deepen.

When you tense your muscles, the muscle spindles in each muscle sense the tension, and these muscle spindles greatly stimulate your worries, making them normal activities, and all the functions of the autonomic nervous system, hormone secretion, etc. are balanced. .

When relaxation is applied after muscle tension, the relaxation is large because it occurs immediately after the muscle tension, and the gradual relaxation increases, and the imaginative activities of great anxiety become more active, and the ASC becomes even deeper.

To describe the process of introducing ASC, the patient's mind becomes unstable due to the movement of chair 1 and its return, and when the patient concentrates on the shaking of the body, the impulses of other senses become Since transmission is blocked at the synapses in the middle of the sensory nerve pathway to prevent the great anxiety from reaching the neocortex, the activity of the neocortical system slows down and eventually becomes dormant. Under such ASC conditions, hypnotic treatment of patients is easy.

Effects Conventionally, large-capacity electric motors, speed reducers, clutches, etc. were used, and due to the large inertia of these devices, it was difficult to continuously and alternately raise and lower the chair. The invented device eliminates the need for these devices and uses a hydraulic mechanism and an oil cylinder as the drive source, making it easy to repeatedly raise and lower the chair in a continuous and alternating manner. Because the noise level has become extremely low, the efficiency of introduction into ASC has been increased, and the noise has not interfered with hypnosis treatment, contributing to improved treatment efficiency.

Furthermore, the most significant effect of this invention is that a braking spring is installed between the lever and the vertical frame, so in order to suppress the force applied in the direction of advancing the rod from the chair part to the rod, it reaches the oil cylinder. No air bubbles are generated in the oil by applying negative pressure to the oil.

Therefore, the rod advances and retreats regularly according to the flow of pressure oil, and the rotation of the chair can be accurately controlled by control signals, increasing the efficiency of introduction into the ASC. In addition, a side plate pivot is provided at approximately the center of gravity of the side plate of the chair on which the patient is placed, and the side plate pivot is pivotally supported by a support provided upright on the base frame, and the chair is rotated around the side plate pivot. The mechanism is composed of an oil cylinder, a connecting mechanism, etc., and a braking spring and a buffer spring are used in the connecting mechanism to control the rotation of the chair.
Therefore, the chair part can be rapidly rotated using a small stroke oil cylinder due to the amplifying action of the coupling mechanism part. Therefore, the operation of tilting the chair back and raising it up does not require a large driving force, and can be performed using a high-pressure, low-flow pump driven by a small-capacity motor, greatly improving the efficiency of the device.
