BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical assistance device for allowing a patient using a wheelchair to take a posture in which he or she can easily receive medical care.

[0002]

BACKGROUND OF THE INVENTION People who have long relied on wheelchairs, especially the elderly, are less likely to experience significant mental stress when they need to move from a wheelchair to a couch, such as for dental treatment. Absent. In addition, caring for a patient who has mobility problems and moving it from the wheelchair to the treatment table also places a heavy burden on the caregiver and medical staff. Therefore, it is desirable for patients using wheelchairs to be able to perform diagnosis and treatment while in wheelchairs.

[0003] However, elderly people tend to bend forward because their waists and backs are bent, and it is difficult to change their postures such as lying on their backs because their bodies are stiff. In the case of dental treatment, for example, in the case of dental treatment, the doctor cannot freely look into the oral cavity, and the treatment cannot be effectively performed.

[0004]

SUMMARY OF THE INVENTION The present invention has been made against such a background, and it is an object of the present invention to provide a medical assistance device for allowing a patient using a wheelchair to effectively perform medical treatment even while in a wheelchair.

A front wheel support portion for supporting the front wheel of the wheelchair is provided on the front end side, and is connected to the base frame so as to be tiltable at an intermediate position, a lever body, a locking means for fixing the lever body to the base frame, and a patient's lock means. It is equipped with a headrest that supports the head, and by tilting the lever body, the wheelchair is tilted backward to a desired angle with the rear wheel as a fulcrum, and in this state the lever body is fixed to the base frame by the locking means. By doing so, it is possible to maintain the tilted state of the wheelchair at the desired angle.

In order to use this medical assistance device, first, the medical assistance device is placed on the floor. Then position the wheelchair in front of the medical assistance device, then retract the wheelchair and deposit the rear wheels on the base frame. As a result, the wheelchair restricts the front and rear movements of the rear wheel by the base frame, and the front wheel is supported by the front wheel support portion of the lever from below. When the lever body is tilted rearward in this state, the lever body lifts the front wheel by its front wheel support portion, and accordingly, the wheelchair leans backward with the rear wheel in the restricted state as a fulcrum. When this inclination reaches the required angle, the lock means is operated to fix this angle state.

Regarding the angle of inclination given to the wheelchair, in the case of dental treatment, about 30 ° is the most suitable for satisfying the two conditions that the treatment can be sufficiently performed and the patient does not feel anxiety. It has been experimentally found to be the preferred angle.

The medical assistance device according to the present invention as described above is characterized in that the tilting of the wheelchair is performed with the rear wheel of the wheelchair itself as a fulcrum. Therefore, the patient can easily tilt the wheelchair with a small force. As a result, the burden on the caregiver and the medical staff can be reduced even when the lever body is manually operated. Further, the use of the rear wheel of the wheelchair leads to a simple mechanism for tilting, which further reduces the weight of the entire vehicle. The fact that it can be easily and lightly brought brings about a great advantage that it can be easily used even during medical treatment on a business trip to nursing homes and homes.

The headrest in the medical assistance device according to the present invention can be mounted on, for example, an appropriate part of a wheelchair, but it requires a mounting work each time, and a caregiver's burden is burdened. Increase. Therefore, it is preferable to attach it to the device itself in advance. In particular, since the lever body is tilted together with the wheelchair and is located at the center of the wheelchair due to its functionality, it is preferable to provide the lever body at the rear end side.

Further, in the medical assistance device according to the present invention, it is preferable that the tilting connection point of the lever body with respect to the base frame is provided at a position substantially directly below the center of gravity of the wheelchair with the rear wheel stored in the base frame. . By doing so, the tilting resistance can be dynamically minimized.

Further, the medical assisting device according to the present invention is preferably foldable in order to facilitate the carrying during the medical treatment on a business trip to each home, in which a lever body is used with the tilting connection point as a fulcrum. The structure that allows folding is rational.
