Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an orthostatic training device for enabling patients with heart failure due to long-term bed rest to be able to stand up and walk without danger after recovery.

If a patient undergoing long-term bed rest tries to get up and walk after healing, he or she may suffer from cerebral anemia, dizziness, etc. due to heart weakness, and may fall. For this reason, stand-up training devices have been developed to allow people to stand up and walk while avoiding such risks.

As a standing training device, for example,
As shown in the above publication, it is generally known that a bed plate for holding a patient is provided so as to be movable up and down, and the inclination angle of the bed plate is adjusted between a horizontal state and a substantially vertical state.

However, in the above-mentioned stand-up training device, the inclination angle of the bed plate can only be adjusted between a horizontal state and a substantially vertical state, so if a patient develops anemia symptoms during stand-up training, the inclination angle of the bed plate can be adjusted. The limit is to keep it in a horizontal position, and in that case, it is not possible to introduce a large amount of blood into the cerebral blood vessels. For this reason, in the above device, when a patient develops anemia symptoms, measures such as setting the bed plate in a horizontal position, lowering the patient from the bed plate, and lowering the patient's head lower than the patient's feet are taken. However, it is not very desirable in terms of speed.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a stand-up system that can quickly and reliably take appropriate measures against the patient's anemia symptoms even if the patient develops anemia symptoms during stand-up training. Our goal is to provide training equipment.

In order to achieve such an object, the present invention provides an upright training device in which a bed plate for holding a patient is provided so as to be movable up and down, and the inclination angle of the bed plate is adjusted. The possible range is set such that the side of the bed plate where the patient's head is placed can fall down beyond the horizontal state, and an emergency start means for starting the fall movement of the bed plate is provided, and the range is a fall movement area of the bed plate. The stopper is arranged such that when the stopper contacts the base plate, the side of the base plate where the patient's head is located is lower than the side of the base plate where the patient's feet are located.

With the above configuration, the inclination angle of the bed plate holding the patient can be adjusted and the patient can be repeatedly trained to adapt to the standing position, while the emergency start means can be activated if anemia symptoms occur during the process. By doing so, the bed plate is moved to fall down, and the bed plate is reliably stopped at the desired tilted state by contacting with the stopper. This ensures a so-called reverse slope condition, which is favorable for the removal of stress and for reducing the load on the heart. Moreover, since this tilted state of the patient can be obtained using the bedplate, there is no need to take the trouble to lower the patient from the bedplate in order to take appropriate measures for anemia symptoms.
This means that patients' anemia symptoms can be dealt with quickly.

Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

In FIGS. 1 and 2, reference numeral 2 denotes a housing housing the lift mechanism 1, and a pair of leg frames 3 are provided in parallel on both side walls of the housing 2.

The lower end of the front leg 8 supports a front wheel 7. The support frame portion 9 is
The legs 8 are inclined downwardly from the upper end thereof so as to proceed rearward, and in this embodiment, the angle of inclination is 10 degrees with respect to the horizontal plane. The rear leg 11 is provided at the lower end of the support frame 9 so as to extend downward from the lower end, and the rear wheel 10 is supported at the lower end of the rear leg 11 .

The base plate 5 is constructed by fixing a mat 13 to a frame 12. A projecting portion 14 is formed on the mat 13 on the side where the patient's head is placed, and the projecting portion 14 is formed as the bed plate 5 falls down (clockwise rotation of the bed plate 5 in FIG. 2). The support frame portion 9 serving as the aforementioned stopper faces the movement area.

A band 15 for tightening the patient's abdomen is attached to the frame 12, and a support shaft 16 is disposed slightly behind the band 15. Its spindle 16

Both ends of a winding rod 21 are fixed to the upper surface thereof, and between the winding rod 21 and both sides of the base plate 5 are bands 22, 22', 23 for tightening the lower leg and thigh. 2
3' is crossed. Further, a support rod 24 that extends horizontally in the lateral direction is provided at the front end (left end in FIGS. 1 and 2) of the mounting member 20.
Foot receiving plates 26 are provided at both ends via mounting rods 25. Further, an operation panel 27 provided with switches, buttons, etc. is provided at the rear of one side of the base plate 5.

Girder members 30 and 31 are stretched between both the support frame parts 9. The housing 2 is firmly fixed to the beam members 30 and 31, and a pair of mounting members 32 are provided to protrude from the beam members 31 toward the front inside the housing.
A support shaft 33 is provided at the tip of each mounting member 32 to protrude inward, and a gear box 34 is pivotally supported on both support shafts 33.

The screw rod 6 is driven by a motor 39 to move up and down at a desired speed.

The operation of the device of the present invention constructed as described above will be explained in the fifth section.
This will be explained together with the electrical control section shown in the figure.

The power switch 43 is closed to apply an AC voltage to the speed control circuit 51 and the processing circuit 45, and the power supply unit 44 converts the AC voltage to a DC voltage.
Enter. Then, in order to position the bed plate 5 horizontally using the reset switch 46, and at the same time maintain the side of the bed plate 5 on which the patient's head is placed at a desired inclination angle for a desired time, the angle setting knob 47, the time setting knob 48, and Rising speed setting knob 4 of screw rod 6
Set the rotation of 9. In this case, the angle setting knob 47
With this, the base plate 5 can be adjusted from a horizontal 0° position to an 80° upright position and stopped in 5° steps, and the time setting knob 48 can be used to adjust the time to maintain the desired tilt angle position for 5 to 30 minutes. It can be adjusted in 5 minute steps within the range of
Accordingly, the rate of rise of the screw rod 6 can be appropriately adjusted according to the patient so as not to cause danger or discomfort to the patient.

After that, when the start switch 50 is closed, the angle and time setting signals of the knobs 47 and 48 are transmitted to the processing circuit 4.
5, the set speed signal of the knob 49 is input to a drive circuit 52 via a speed control circuit 51, and the drive circuit 52 rotates the motor 39 at the set speed. As a result, the screw rod 6 moves the base plate 5 toward the set inclination angle and moves up (raises) at the set speed.
After that, the tilt angle of the base plate 5 is detected by the angle detector 53 connected to the output shaft of the motor, and the detection signal is input to the processing circuit 45. In the processing circuit 45, the detected angle signal and the set angle signal are compared, and the processing circuit 4
5 sends a motor normal rotation signal to the drive circuit 52 until the detected angle becomes equal to the set angle, and when the set angle and the detected angle become equal, sends a motor stop signal to the drive circuit 52 to stop the motor 39. .

The base plate stopped at the desired inclination angle by stopping the motor 39 maintains the stopped position for a time interval set by the knob 48, and when the set time has elapsed, the buzzer 55 is excited by a signal from the processing circuit 45. When the buzzer 55 finishes excitation, the reset switch 46
This allows the base plate 5 to return to the horizontal position.

When the patient completes the above-mentioned training without causing cerebral anemia, the next training is performed at an appropriate time interval. In that case, the inclination angle of the base plate 5 to be set,
The maintenance time at the tilt angle position and the rate of rise of the bed plate are slightly increased depending on the patient's adaptability.
Then, when the patient can tolerate the inclination angle of the bed plate 5 to 80 degrees, the training is completed.

In addition, during the above training, in order to prevent erroneous mechanical operation by the training instructor, the knobs 47 and 4
8 and 49 are shown on a display 56 consisting of a cathode ray tube connected to the processing circuit 45.

If a patient develops cerebral anemia during training, an emergency switch 57 as an emergency start means can be pressed to take measures against the cerebral anemia.

That is, when the emergency switch 57 is pressed, a signal is input from the processing circuit 45 to the speed control circuit 51 with priority over other setting signals, and based on the signal, the drive circuit 52 connected to the speed control circuit controls the motor 3.
9 is reversed. As a result, the base plate 5 is caused to fall down at the maximum speed, and the fall movement is as follows.
The projecting portion 14 of the base plate 5 is stopped when it comes into contact with the support frame portion 9 serving as the aforementioned stopper. At this time, the bed plate 5 has a negative side on the side where the patient's head is placed.
It is tilted in the opposite direction at an angle of 10 degrees to facilitate the introduction of the patient's blood into the cerebral blood vessels.

Therefore, when the patient develops anemia symptoms, the bed plate 5 can be reliably stopped in the desired tilted state by contacting the support frame 9, and the patient can be helped to eliminate the anemia symptoms. This makes it possible to ensure the so-called reverse slope condition, which is favorable for reducing the load on the internal organs. Moreover, since this tilted state of the patient can be obtained by the bed plate 5, there is no need to take the trouble of lowering the patient from the bed plate 5 in order to take appropriate measures for anemia symptoms, and the above-mentioned rapid lodging movement speed of the bed plate 5 is eliminated. Together with,
This means that anemia symptoms can be dealt with quickly.

Thereafter, when the patient's cerebral anemia condition recovers, the reset switch 46 returns the bed plate 5 to the horizontal position.

If the patient feels that cerebral anemia may occur if the patient is tilted any further while the bed plate 5 is being raised to the set inclination angle, the patient can press a foot switch 58 placed near the patient's foot with his or her own foot. It's becoming like that. As a result, the processing circuit 45 sends a signal with priority over the angle setting signal to the drive circuit 52 to stop the motor. As a result, the base plate 5 stops, and after a certain period of time has elapsed after the stop, the buzzer 55 is excited. And furthermore, foot switch 5
When 8 is pressed, the base plate 5 rises to the set angle position and then stops.

As described above, the present invention can provide a stand-up training device that can quickly and reliably take appropriate measures for the patient's anemia symptoms even if the patient develops anemia symptoms during stand-up training.
