Description

Bed type rehabilitation exercise equipment {REHABILITATION EXERCISE EQUIPMENT}

The present invention relates to a bed-type rehabilitation exercise device, and in particular, provides safe rehabilitation exercise even for users who are difficult to voluntarily move by rolling left and right while lying down on a bed to which a crank exercise force is transmitted to a patient or an elderly user with limited mobility. It relates to a bed-type rehabilitation exercise device whose structure has been improved so that it can be done.

In general, beds used for patients with disabilities have a structure in which the patient's backrest is angled upward, providing convenience in use. Separately, the mattress located on the patient's leg is operated manually or electrically. It is configured to be angle-adjusted upward by the driving force.

Therefore, patients with discomfort can raise one side of the mattress to watch TV, read, and take a break, and the angle adjustment structure of the mattress is made by raising and lowering the screw shaft by the rotation of the driving motor. It has a structure that can be used conveniently by controlling the operating time of the driving motor and adjusting it to a desired angle.

In addition, the lower one side of the patient's 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 itself. Because of the inconvenience, it is common to adopt a bed with an automatic angle adjustment structure.

However, since the angle adjustment structure of the patient bed as described above is to adjust the angle by simply rotating only one side of the mattress upward, it does not conform to the physical structure of the patient, so that after using for a certain period of time, the patient feels uncomfortable. When moving out of the bed, the patient's lower body is still staying on the upper side of the bed, so there is a problem in that the patient with discomfort needs excessive movement.

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

Therefore, as in Patent Registration No. 0622342, by dividing the bed frame into a plurality and adjusting the angle of each of the bed frames by an actuator, thereby adjusting the upward angle of the mattress on the back side of the user, as well as to the thigh, calf, and ankle of the patient. By rotating the divided frame, it is possible to adjust the angle of the patient's lower body, allowing you to rest in a more comfortable position, while maintaining the most stable state according to the patient's body condition by adjusting the angle of various mattresses even while lying on the bed. When the patient wants to move out of the bed, a frame structure for adjusting the angle of the mattress of the patient bed is registered, which has the effect of allowing the mattress to be angled in a complete chair shape so that it can move more easily from the bed or lie down again. It is published in the patent publication.

However, the multi-stage divided frame structure as described above allows the patient bed to have only limited movement when the patient wakes up, lies down, or wants to take a break, so patients or critically ill patients with disabilities can lie on the bed for a long time. If there is, there is little movement of each joint, so you can feel the function of the joint is impaired or 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.If you are lying on a bed for a long time, these joints hardly move, so the flexibility of the joints is greatly reduced. There is a problem that becomes stiff.

In particular, in the case of critically ill patients, patients with discomfort, or elderly patients, the above problems are more severe.To prevent this, the patient himself or the caregiver forcibly moves each part of the body so that the flexibility of these joints can be continuously maintained. I am doing it.

At this time, as described above, if the exercise environment is poor or the patient cannot exercise at the will of the patient, exercise is inevitable with assistance from a caregiver. Such exercise by indirect external force controls the patient's own body. It is not possible to exercise excessively or cause serious damage to joints, which is the cause of harming health.

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

The "bed with exercise equipment" of the above Utility Model Publication No. 2008-0003515 consists of a pedal part and a bed part, and the bed part is an operating rod combined with an actuator, and both sides of the bed move up and down, and a wheel installed inside the bed part. One inner bed part and pedal part with pedals are moved up and down in the same direction with the bed part by wheels and rails, respectively, so it can be used conveniently for patients who live in bed for a long time and when simple exercise is needed before bedtime. It is a bed with equipment.

However, the "bed with exercise equipment" of the Utility Model Publication No. 2008-0003515 is that only the user can perform leg exercises by stepping on the pedal, and whether or not the user has the ability to rotate the pedal axis by stepping on the pedal. Since this was not considered, there was a drawback that it was difficult or impossible to use a patient with a leg disorder who lacks the ability to rotate the pedal axis 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 with exercise means" of the patent registration number 0864733 is a medical bed in which a mat is installed on an upper part of a bed frame, a guide bar installed on one side of the lower end having a space part vertically formed in the lower central part of the bed frame, and the guide A slider provided to be moved by a belt that is a driving means along the bar, a rack gear installed on the other side of the lower end having the space portion formed, and a connection slider having a pinion gear having a shaft hole formed in the center to rotate in engagement with the rack gear; The connecting slider has one side guided to the rack gear and the other side is fixed to the slider, and the lower pivot shaft of the leg exercise mechanism in which the footrest is installed so as to rotate on both sides of the upper side in the shaft hole of the pinion gear installed in the bearing on the inner side of the connecting slider. It is installed so that the slider is moved back and forth by the forward and reverse rotation of the motor, and the footrest of the leg exercise machine is rotated up and down to fold and unfold the patient's knee, and the rotation movement motion can be repeated up and down. will be.

Therefore, not only does not take into account the patient's ability to use the patient's leg at all, and because it is forcing the patient to perform leg movements with the forward and reverse rotation of the motor, it is not only a defect that rehabilitation exercises cannot be performed according to the patient's ability to use the leg, but also There was also a problem that it was impossible to exercise the body parts together.

In addition, the existing rehabilitation exercise equipment may cause a safety accident for the patient if the patient performs an unreasonable motion on the patient due to an assistant's error or malfunction of the rehabilitation device during the rehabilitation exercise.

Korean Utility Model Publication No. 2008-0003515 "Bed with exercise equipment" (Publication date: 2008.08.26) Korean Patent Registration No. 0864733 "Medical bed with exercise means" (Registration date: 2008.10.15)
