Description

Bed type rehabilitation exercise equipment {REHABILITATION EXERCISE EQUIPMENT}

The present invention relates to a bed-type rehabilitation exercise device, and in particular, provides a safe rehabilitation exercise for a user who has difficulty in voluntary movement by rolling a patient or an elderly user in a state of lying on a bed and rotating it left and right, as well as a patient lying down for a long time It relates to a bed-type rehabilitation exercise device whose structure is improved so as to prevent bedsores occurring in cases.

In general, a bed used for a patient with poor mobility has a structure in which the patient's backrest is angled upward, providing convenience in use. Separately, the mattress located in the patient's leg is manually operated or electrically operated. It is configured to adjust the angle upward by the driving force.

Therefore, a patient with poor mobility can watch TV or read and rest by raising one side of the mattress, and the angle adjustment structure of this mattress is made according to the elevation of the screw shaft by the rotation of the drive motor, and the patient himself It has a structure that can be used conveniently by controlling the operating time of the driving motor to adjust it to a desired angle.

In addition, the lower side of the patient bed as described above is configured to allow angle adjustment by manual operation as well as angle adjustment by the drive motor as described above, but in recent years, the patient cannot adjust the angle by himself. It is common to adopt a bed with an automatic angle adjustment structure for most of the inconvenience.

However, since the angle adjustment structure of the patient bed as described above simply rotates one side of the mattress upward to adjust the angle, it does not conform to the patient's physical structure and causes discomfort after use for a certain period of time. When moving out of the bed, the patient's lower body is still on the upper side of the bed, so there is a problem in that excessive movement is required for the patient with poor mobility.

In addition, when taking a break by simply raising only the upper body, the lower body of the patient is positioned horizontally on the bed, so if this state is maintained for a long time, there is an inconvenience of feeling a blood circulation disorder or numbness in the legs.

Therefore, as in Patent Registration No. 0622342, the bed frame is divided into a plurality of pieces and the angle is separately adjusted by the actuator, thereby adjusting the upward angle of the user's back mattress as well as the patient's thighs, calves, and ankles. By rotating the divided frame, it is possible to adjust the angle of the patient's lower body, allowing for a more comfortable rest, while maintaining the most stable state according to the patient's body condition by adjusting the angle of various mattresses even when lying on the bed. A frame structure for adjusting the angle of the mattress of the patient's bed is registered, which has the effect of allowing the mattress to be angle-adjusted to a complete chair shape and to move from the bed more easily or to lie down again when the patient wants to move out of the bed It is published in the Patent Gazette.

However, since the patient bed with the multi-stage divided frame structure as described above has only a limited form of movement when the patient gets up, lies down, or wants to take a rest, the patient or the critically ill patient who is inconvenient in movement can lie on the bed for a long time. If there is, there is almost no movement of each joint, so the function of the joint is damaged or it becomes stiff.

In other words, the hip, knee, and ankle joints, which are important joints of the human body, are particularly important joints for walking and movement. There is a problem that it becomes stiff.

In particular, in the case of critically ill, mobility-impaired, or elderly patients, the above problems become more serious. To prevent this, the patient himself or the caregiver forcibly moves each part of the body to continuously maintain the flexibility of these joints. is doing

At this time, as described above, when the exercise environment is poor or the patient cannot exercise by their own will, the exercise is inevitably performed with the help of a caregiver. It is impossible to do it, and it can cause excessive exercise or serious damage to the joints, which is the cause of harming health.

On the other hand, as a conventional "bed with exercise equipment" as a bed-type exercise equipment, Utility Model Publication No. 2008-0003515 has been published in the Public Utility Model Publication.

The "bed with exercise equipment" of the Utility Model Publication No. 2008-0003515 has a pedal part and a bed part, and the bed part is an actuating rod coupled with an actuator, and both sides of the bed move up and down, and the wheeled or bed part installed inside the bed part One inner bed part and the pedal part with pedals, respectively, move up and down in the same direction with the bed part by wheels and rails, so it is a convenient exercise for patients who live in bed for a long time and when simple exercise is needed before going to bed. It is a bed with equipment.

However, the "bed provided with exercise equipment" of the Utility Model Publication No. 2008-0003515 is that only the user can exercise the leg by stepping on the pedal, and whether the user has the ability to rotate the pedal shaft by stepping on the pedal. Because it was not taken into account, there was a drawback that it was difficult or impossible to use for a patient with a leg disorder who had a lower ability to rotate the pedal shaft by stepping on the pedal.

As developed in consideration of the above circumstances, "Medical Bed with Exercise Means" of Patent Registration No. 0864733 is published in the Registered Patent Publication.

The "medical bed having an exercise means" of Patent Registration No. 0864733 is a medical bed having a mat installed on the upper portion of the bed frame, a guide bar installed on one side of the lower end in which a longitudinal space is formed in the lower central portion of the bed frame, and the guide A slider provided to be moved by a belt as a driving means along the bar, a rack gear installed on the other side of the lower end where the space part is formed, and a connection slider having a pinion gear having a shaft hole formed in the center to be rotated in engagement with the rack gear installed therein; One side of the connecting slider is guided to the rack gear and the other side is fixed to the slider, and the lower rotational shaft of the leg exercise mechanism in which the footrest is installed to rotate on both sides of the upper side in the shaft hole of the pinion gear installed in the bearing inside the connecting slider. It is installed in such a way that the forward and reverse rotation of the motor moves the slider back and forth and rotates the footrest of the leg exercise device up and down to fold and unfold the patient's knee, and repeat the up and down rotation movement. will be.

Therefore, since it is forcibly allowing the patient to exercise the leg by the forward and reverse rotation of the motor without considering the ability to use the patient's leg, not only the drawback that rehabilitation exercise cannot be performed according to the usage ability of the patient's leg, but also other than the leg There was also the problem that the body parts of the body could not be exercised together.

In addition, the existing rehabilitation exercise equipment may cause a patient's safety accident if the patient performs an operation that is burdensome to the patient due to an assistant's mistake or an erroneous operation of the rehabilitation apparatus while the patient is performing the rehabilitation exercise.

In addition, the lifting rod 220 is configured in the form of a pipe having a rectangular cross-sectional structure so as to be stretched and fit inside the hollow of the connection frame 150 having a rectangular tube structure.

Here, the lifting mechanism 200 is illustrated as being provided inside the connection frame 150 , but the electric cylinder 210 may be disposed inside the support frame 130 .

The lifting frame 300 is supported by the lifting rod 220 to move up and down, and the support member 500 is in contact with the bed mattress 50 when not used as a rehabilitation exercise device to contact the support member. (500) performs the function of the cover cloth of the mattress (50).

On the contrary, as shown in FIGS. 4 and 5 , when the lifting frame 300 is raised by the lifting mechanism 200 of the support member 500, the support member 500 is the bed mattress ( 50) is spaced upward from the state to perform a function of separating the user from the fixed bed mattress (50).

To this end, the support member 500 is coupled such that one end is fixed to the first drive shaft 410 and the other end is coupled to be fixed to the second drive shaft 420, and when the user is seated in a lying state, an elastic force is provided. It is composed of a fiber material with its own tension.

On the contrary, the lifting frame 300 is lowered so that the support member 500 is positioned at the lower position position located on the upper side of the bed mattress 50 in normal times other than the rehabilitation exercise.

During the rehabilitation exercise, the height of the lifting frame 300 may be adjusted according to the user's physical condition, and even if the sagging of the support member 500 due to the weight of the user occurs while the user is lying on the support member 500, the middle The drooping support member 500 maintains a height enough not to contact the bed mattress 50 .

Although the elevating mechanism 200 of the present invention has been described as being disposed inside each of the connection frames 150 arranged in the front and rear sides, it may be applied only to one of the connection frames 150 on the front and rear sides.

1 and 3, the first and second drive shafts 410 and 420 are supported by supporters 415 and 425 having bearings at both ends in the longitudinal direction on both left and right sides of the elevating frame 300, respectively. rotatably arranged.

In addition, the first driving motor 610 is disposed on the left side of the lifting frame 300 , and transmits the rotational driving force to the first reducer 615 .

The second driving motor 620 is disposed on the right side of the elevating frame 300 , and transmits a rotational driving force to the second reducer 625 .

The first and second driving motors 610 and 620 may employ an AC motor, and have a structure in which a motor shaft is connected to the first and second reducers 615 and 625 .

Since the driving speed of the first and second driving motors 610 and 620 is variable by an operation button not shown, the first and second driving shafts in the rolling motion mode and the pressure ulcer prevention mode of the support member 500 according to the user It has the advantage of being able to adjust the rotation speed of (410, 420).

The control unit 700 outputs control signals to the first and second driving motors 610 and 620 to suit the corresponding mode selected from the rolling motion mode or the pressure ulcer prevention mode, respectively.

The first and second driving motors 610 and 620 alternately rotate the support member 500 in opposite directions in forward and reverse directions according to a control signal from the control unit 700 .

When selecting the rolling motion mode, first, one of the first and second driving motors 610 and 620 is driven in the reverse direction to reduce the tension of the support member 500 by the control signal of the controller 700, and then the support The first and second driving motors 610 and 620 are alternately rotated in the forward and reverse directions to rotate the user seated on the member 500 left and right.

The support member 500 has a greater tension force in the pressure ulcer prevention mode than in the rolling motion mode under the control of the controller 700 .

"50" in FIG. 6 indicates a bed mattress, and "55" indicates a main frame that is coupled to be fixed to each of the connection frame 150 or fixed frame 100 to support the bed mattress 50 .

Since the lifting frame 300 is lifted by the lifting mechanism 200 when the rolling motion mode or the pressure ulcer prevention mode is selected, the support member 500 is lifted to be spaced apart from the upper side of the main frame 55 .

In the bed mattress 50, the support member 500 is seated on the upper side during the lowering operation of the elevating frame 300 by the elevating mechanism 200 to perform the original function of the bed.

That is, in the present invention, when the pressure ulcer prevention mode or the rolling motion mode is selected, the control unit 700 uses the lifting mechanism 200 to raise the lifting frame 300 upward, and the first and second driving motors 610 and 620 ), the first and second drive shafts 410 and 420 are rotated forward and reverse in opposite directions to alternately move the support member 500 left and right.

In addition, as shown in FIG. 6 , the present invention is disposed under the bed mattress provided on the lower side of the support member 500 , and measures the user's weight and outputs the weight sensor 710 to the control unit 700 side. provide more

The weight sensor 710 detects the weight when the user is lying on the bed mattress, and outputs the weight information to the control unit 700 side, so that the control unit 700 is a support member suitable for the user's variable body weight. A control signal for adjusting the tension of 500 is output.

The control unit 700 may adjust the rotation direction of the first and second driving motors 610 and 620 to adjust the tension of the support member 500 having both ends wound around the first and second driving shafts 410 and 420 .

In the present invention having such a configuration, both ends of the support member 500 are normally supported by the first and second drive shafts 410 and 420 to perform the function of a cover cloth covering the upper side of the bed mattress 50, but on the contrary, the user When selecting the rolling exercise mode or the pressure sore prevention mode for the rehabilitation exercise of the control unit 700, the lifting mechanism 200 is operated to operate the electric cylinder 210 in the direction to raise the lifting frame 300, and the electric cylinder As the lifting rod 220 is withdrawn to the upper side of the connection frame 150 by 210 , the lifting operation is performed, and the lifting frame 300 is raised upward by the lifting rod 220 .

When the lifting frame 300 is raised, the first and second drive shafts 410 and 420 and the support member 500 rise together, and thereby the support member 500 is a bed mattress ( 50), a gap h1 spaced upwardly is generated.

At this time, the support member 500 is a state in which the left and right both ends are coupled by the first and second drive shafts 410 and 420 , and the middle portion where the user is lying is spaced apart from the bed mattress 50 .

Thereafter, the user or caregiver operates an operation button (not shown) to select one of the rolling exercise mode or the pressure sore prevention mode.

[In rolling motion mode]

When the rolling motion mode is selected using the operation button, the control unit 700 outputs a control signal to one of the first and second driving motors 610 and 620, and the output control signal is applied to the first and second driving motors 610 and 620. ) is driven in the reverse direction, and the middle portion of the support member 500 droops downward due to the user's load.

The user is supported while lying on the support member 500 , the first and second drive shafts 410 and 420 are alternately rotated left and right, and when the first and second drive shafts 410 and 420 alternately rotate, the support member 500 ) is wound or unwound, and thus the user lying on the drooping middle portion of the support member 500 is rotated by rolling left and right.

In the rolling motion, as the first and second driving motors 610 and 620 are alternately driven in the forward and reverse directions, the rotational driving force of the first and second driving motors 610 and 620 is transmitted through the first and second reducers 615 and 625. Since it acts as a force to rotate the first and second drive shafts 410 and 420 in the forward and reverse directions, the user lying on the support member 500 can roll left and right.

At this time, when the first drive motor rotates the support member 500 in the forward direction so as to wind the first drive shaft, the second drive motor rotates the second drive shaft in the reverse direction to be wound around the second drive shaft. By performing the function of releasing the supporting member 500, the supporting member 500 may be rotated by rolling left and right to maintain a constant tension as before the driving of the first and second driving motors 610 and 620 .

Accordingly, the support member 500 is rotated while the first and second drive shafts 410 and 420 are alternately rotated left and right, and the user is rotated by rolling so that centrifugal force is generated on the support member 500 in which the middle portion is drooping.

[In Bedsore Prevention Mode]

When the pressure ulcer prevention mode is selected using the operation button, the control unit 700 outputs a control signal for driving in the forward direction to one of the first and second driving motors 610 and 620 to increase the tension of the support member 500 in the rolling motion mode. The operation of the first and second driving motors 610 and 620 is controlled so as to have a tension force greater than the tension at the time of selection.

As a result, as shown in FIG. 7 , in a state in which the user is lying, the support member 500 maintains the tension so that the tension is adjusted so as not to cause sagging by the control signal of the control unit 700 to approach the horizontal state. will do

Thereafter, as the control signal of the control unit 700 is output to the first and second driving motors 610 and 620, the first and second driving motors 610 and 620 are alternately driven to rotate in the forward and reverse directions, 410 and 420 are rotated in the forward and reverse directions to move the support member 500 in the horizontal direction on both sides of the left and right sides.

At this time, when the support member 500 moves to the left, as shown in FIG. 8A , a first angle inclined with the upper side of the support member 500 by the user's frictional force with the support member 500 moved to the left. The user's back (not shown) is spaced apart from the support member 500 while being lifted at (θ1).

Conversely, when the support member 500 moves to the right, as shown in FIG. 8B , the user is inclined at a second angle with the upper side of the support member 500 by frictional force with the support member 500 moved to the right. The user's back (not shown) is spaced apart from the support member 500 while being lifted by (θ2).

That is, while the support member 500 is alternately moved to the left and right, the user's back is spaced apart from the upper side of the support member 500 alternately at a first angle and a second angle to stimulate the user. By ensuring smooth blood circulation in the back, it is possible to prevent bedsores from occurring.

Therefore, the present invention can not only be applied to an existing bed because it does not interfere with the original function of the bed in normal times, but also during the rehabilitation exercise, after the user is lifted from the bed mattress on the support member 500, the support member in the rolling motion mode It has centrifugal force as it is rotated by rolling through 500, and by the centrifugal force, blood circulation is smoothed and the muscles are relaxed, as well as a rolling exercise that can obtain an exercise effect of becoming flexible due to the movement of the joint area, or pressure sores In the prevention mode, while the support member 500 is alternately moved to the left and right in a horizontal state, the user's back is spaced apart from the upper side of the support member 500 alternately at a first angle and a second angle, It has a useful advantage of being able to perform a function of a rehabilitation exercise that can prevent the occurrence of pressure sores by smoothly circulating blood in the user's back according to stimulation.

In addition, according to the present invention, the height of the lifting frame 300 and the left and right rotational speed of the support member 500 can be arbitrarily adjusted according to the user's physical condition or the user's preference by using the lifting mechanism 200, so that the user's It has the advantage of increasing convenience.

In addition, the present invention has the advantage of being able to comfortably perform rehabilitation exercise while lying in bed even for an elderly user or patient who has difficulty in self-movement, and can prevent safety accidents by adopting a rehabilitation exercise method that does not put a strain on the body. .

In addition, the present invention has the advantage of being able to perform a rehabilitation exercise function to be suitable for users having various physical conditions using the weight sensor 710 , thereby increasing user convenience.
