Description

[Detailed description of the invention] Industrial application field The present invention aims to put patients in a hypnotic state, that is, an altered state of consciousness (hereinafter referred to as "altered state of consciousness"), in order to administer hypnotic treatment to patients with psychogenic diseases.
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 connected to the output shaft of a speed reducer linked to an electric motor by a crank. The arm is fixed, the crank arm is connected to a support shaft at the rear end of the pedestal, and by rotating the support shaft, the raising and lowering operation section is operated to raise and lower.

The problem that the invention attempts to solve: The hypnotist (hereinafter referred to as the patient) placed on a chair.
Conventional chairs rotate within a predetermined angle range in order to create tension and relaxation.Firstly, the pivot point is not approximately at the center of gravity of the chair, so rotating the chair requires a large-capacity motor and deceleration. The drawback was that it required a drive source such as a machine. Second, since the drive source has a large capacity, the inertia of the drive source is large and it is difficult to alternately drive the chair parts continuously. Thirdly, the noise and vibration of the drive source is also high. It had the disadvantage of being large in size.

Fourthly, impact vibrations occur at the stop position of the rotational movement of the raising/lowering operation section, which causes discomfort to the patient, and furthermore, the impact vibrations lead to early damage to the device.

Means for Solving the Problems The present invention is a new device that eliminates the drawbacks of conventional devices.It is capable of rapidly and continuously tilting back and standing up with high efficiency, and has extremely low operating noise during the tilting and standing operations. The object of the present invention is to provide an altered state of consciousness induction device with a buffer spring that eliminates low and unnecessary shocks.

That is, in the present invention, the chair part 1 is constructed by standing the backrest part 3 at the rear end of the flat seat part 2, and the side plates 5 are attached to both sides of the upper surface of the seat part 2, and the backrest part 3 is The side plate pivot portion 6 located in front and above the seat portion 2 is connected to the side plate 5.
A pivot portion 9 is provided on the side plate 5 at a position near the side plate pivot portion 6, and a support 8 for pivotally supporting the side plate pivot portion 6 is provided on the base frame 7 placed on the floor. Furthermore, an oil cylinder 10 that extends and contracts is provided on the base frame 7, and the pivot portion 9 and the rod 12 of the oil cylinder 10 are connected by a connecting mechanism portion 13, and the upper end of the connecting mechanism portion 13 is connected to the pivot portion. a rod 19 which is pivotally connected to rod 9 and whose lower end is slidably fitted onto rod 12;
A shock absorbing spring 18 is fitted onto the upper part of the rod 1 and connects the rod 12 with the rod 19.
The lower end of the oil cylinder 10 is pivotally attached to the base frame 7, and is an altered state of consciousness induction device with a buffer spring.

Function: The support 8 holds the side plate pivot 6 of the side plate 5, and the connecting mechanism 13 connects one end to the pivot 9 of the chair 1, which is rotatable around the side plate 5. Push up 9 and pull it down to its original position. The other end of this coupling mechanism section 13 is pushed up and down by a rod 12 of an oil cylinder 10.

When the rod 12 advances, the rod 1 of the connecting mechanism section 13 is moved through the spring 18 fitted onto the rod 12.
9 is pressed, and the rod 19 transmits this pressing force to the pivot portion 9 to push up the seat portion 2 and tilt the chair portion 1 backward.

When the rod 12 is retracted, the rod 19 is retracted, and the pivot portion 9 is pulled down via the rod 19 to return the chair portion 1 from the reclined position to the upright position.

The above-described movement of the chair portion 1 occurs when the pivot portion 9 is provided in the front direction from the side plate pivot portion 6, and when the pivot portion 9 is provided in the rear direction from the side plate pivot portion 6. The direction of rotation of the chair portion 1 is reversed, and the chair portion 1 performs a return operation instead of the above-mentioned backward-tilting operation, and also performs a backward-folding operation instead of the return operation.

The inertial force generated at the beginning and end of the rotation of the chair section 1 is absorbed by the spring 18.

Embodiment A chair part 1 is constructed by sequentially connecting a backrest part 3 and a pillow part 4 upward from the rear end of a seat part 2 on which a patient sits.

The upper half of the backrest part 3 is bent backward so as to allow the patient to assume a hyperextended posture, and side plates 5 are attached to both sides of the seat part 2. The side plate 5 is provided with a side plate pivot 6, and the side plate pivot 6 is pivoted by a pair of columns 8 that project obliquely upward from a base frame 7 placed on the floor. The side plate pivot portion 6 is provided approximately at the center of gravity of the chair portion 1 with the patient sitting thereon.

A pivot portion 9 is provided on the side plate 5 at a position slightly forward of the chair portion 1 from the side plate pivot portion 6.

On the base frame 7 are an oil cylinder 10 , a pressure oil mechanism section 11 that generates pressure oil to drive the oil cylinder 10 and controls opening and closing of a flow path, and a rod 12 extending from a piston 25 of the oil cylinder 10 . A connecting mechanism section 13 is provided between the tip and the pivoting section 9 and transmitting the movement of the rod 12 to the pivoting section 9.

The connecting mechanism section 13 has a rod 19 whose upper end is pivotally connected to the pivot portion 9 and whose lower end is slidably fitted onto the rod 12.
and a spring 18 which is fitted onto the upper part of the rod 12 and connects the rod 12 to the rod 19.

Both ends of the spring 18 are fixed to a collar 20 provided on the shaft 19 and a rod collar 14 provided on the rod 12, and the base end of the oil cylinder 10 is pivotally connected to an oil cylinder pivot portion 24 of the base frame 7.

A throttle valve 27 is provided in a piping route connected to the base chamber 26 of the oil cylinder 10 through which oil flows out when the rod 12 moves in the retracting direction. An oil hose 1 from the hydraulic mechanism section 11 is connected to the throttle valve 27 and the front chamber 28 into which oil is injected when the rod 12 moves in the direction of retraction in the oil cylinder 10.
5 is piped.

The hydraulic mechanism section 11 includes a motor 29 and a pump 3.
0, a control valve 31, a check valve 32, a relief valve 16, etc. are incorporated.

The manual switch 17 that controls the control valve 31 that controls the hydraulic system and the signal recording/reproducing device 21 are housed in an operation box 22 that is separate from the chair section 1.
2 is connected to the control valve 31 by a conducting wire 23.

The patient to be subjected to hypnotic treatment is placed in a sitting position on the aforementioned chair part 1, 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, the patient is introduced into the ASC by repeatedly rotating the chair section 1 rapidly backwards or forwards and gently rocking it back and forth.

Next, the operation of the device will be described.

A side plate pivot 6, which is located at a position where the weight of the front half and the back half of the chair part 1 on which the patient is sitting, is supported by a support 8.

A connecting mechanism part 13, one end of which is connected to the pivot part 9 of the chair part 1, which is rotatable about the side plate pivot part 6, pushes up or lowers the pivot part 9 to its original position. The other end of this coupling mechanism section 13 is pushed up and down by a rod 12 of an oil cylinder 10.

When pressurized oil is rapidly injected from the hydraulic mechanism section 11 into the base chamber 26 of the oil cylinder 10, the rod 12 advances and causes the chair section 1 to fall backward via the coupling mechanism section 13. At this time, oil flows out from the front chamber 28 of the oil cylinder 10. Conversely, when pressurized oil is rapidly injected into the front chamber 28 of the oil cylinder 10, the rod 12 that has advanced moves back and the chair portion 1 returns to its original position. At this time, oil flows out from the base chamber 26 of the oil cylinder 10.

When the rod 12 advances, it pushes the rod 19 via the spring 18 fitted onto the rod 12, and the rod 19 transmits this pressing force to the pivot joint 9, pushing the pivot joint 9 upward and tilting the chair part 1 backward. let

When the rod 12 is retracted, the rod 19 is retracted, and the pivot portion 9 is pulled down via the rod 19, and the chair portion 1 is returned from the reclined position to the upright position.

When the rod 12 is retracted, the retracting speed of the rod 12 is suppressed by a throttle valve 27 provided in the outflow oil pipe of the source chamber 26. Suppose that the speed of the rod 12, which is moved by the oil injected into the front chamber 28, causes the chair portion 1, which rotates back to its original position, to be connected to the rod 1 via the connecting mechanism portion 13.
If the speed at which 2 is pressed becomes faster, the piston 25 rapidly moves downward, and the oil pressure in the front chamber 28 tends to become negative pressure. At this time, if the main chamber 26 is filled with oil whose outflow is suppressed by the throttle valve 27, the piston 25 will be blocked by this oil, and its movement will be suppressed and it will not be able to move downward rapidly, so the oil pressure in the forward chamber 28 will be negative pressure. It won't be.

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 signals from the manual switch 17 of the operation box 22 and the signal recording/reproducing device 21.

In addition, in the device of the present invention, the upper half of the backrest portion 3 is bent backward, so that it is possible to easily support a patient in a hyperextended posture in a backward position.

Next, we will discuss how the movements of this invention affect 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 posture, the patient's mind and body are relaxed, and when the patient is in a hyperextended posture, that is, a supine position, with the upper body slightly bent from the horizontal position toward the back, the patient tenses the body and mind. In addition, the patient sitting on the chair 1, which is rocked back and forth like a cradle, relaxes both mind and body.

The operation of stopping the chair part 1 in the standing position, or the operation of continuously rotating the chair part 1 backward at a slight angle and rotating it forward in the direction of the original position, or the act of suddenly moving the chair part 1 backwards. The action of reclining the chair part 1 to the reclined position, and the returning action of rapidly returning the chair part 1 from the reclined position to the original upright position are repeated, thereby creating tension and relaxation in the patient and deepening the depth of the ASC. .

When you tense your muscles, the muscle spindles in each muscle sense the tension, and these muscle spindles greatly stimulate the cerebrum, resulting in normal functioning, and all the functions of the autonomic nervous system and hormone secretion are balanced.

When relaxation is applied after tension, the relaxation is large because it occurs immediately after the muscle tension, and the gradual relaxation increases, and the imaginative activity of the cerebrum becomes active, further deepening the ASC.

Describing the process of introducing ASC, the patient is seated in chair section 1.
When the mind becomes unstable due to the activation of backward movement and its return, and when we concentrate on the movements of the body in the sense of the neocortical system of the cerebrum, the middle of the sensory nerve pathway is activated to prevent other impulses from reaching the neocortex of the cerebrum. Because transmission is blocked at the synapses, brain activity in the neocortical system slows down and eventually becomes dormant. Under such ASC conditions, hypnotic treatment of patients is easy.

Effects of the invention A spring is attached to the connecting mechanism that rotates the chair, and the forward and backward movement of the rod is transmitted to the chair via the spring, so that the end portion of the chair when the chair rotates clockwise and counterclockwise is fixed. Because it can absorb unnecessary shocks and at the same time generate slight vibrations, it can be used effectively without causing unpleasant stimulation to the patient on the chair.
It can be introduced into ASC.

Also, since the shock of sudden stopping at the end of rotation is eliminated,
This reduces equipment wear and tear and improves durability.

In addition, with conventional equipment that uses large-capacity electric motors, reducers, clutches, etc., it is difficult to continuously and repeatedly raise and lower the chair due to the large inertia of these components. However, the device of the present invention does not use these devices, but uses a hydraulic mechanism and an oil cylinder as the drive source to operate the chair by pushing and pulling the pivot joint, so the chair can be raised and lowered continuously. It is easy to do repeatedly.

In addition, no impact noise is generated at the moving end during the raising/lowering operation.
Because the noise level has become extremely low, the effectiveness of introducing it into ASC has been enhanced, and this is a good factor in improving treatment efficiency because it does not interfere with the noise during hypnosis treatment.

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 this side plate pivot is pivotally supported by a support provided upright on the base frame, allowing the chair to rotate around the side plate pivot. The mechanism for rotating the seat is composed of an oil cylinder, a connecting mechanism, etc., and a shock absorbing spring or the like is used in the connecting mechanism to control the rotation of the chair. For that reason,
Rapid rotation of the chair part is possible using a small stroke oil cylinder. In addition, the chair does not require a large amount of driving force to tilt back and raise up, and can be performed using a high-pressure, low-flow pump driven by a small-capacity motor, resulting in energy savings and high efficiency of the device.
