Abstract
A bed for immobilized patients and method for adjusting such a bed comprising a motor-driven, oscillating patient support platform mounted for longitudinal rotation about axes spaced above the platform at a predetermined distance and having a counter balance keel extending below the platform for attachment of varying counter balance weights, and having a slip clutch set to slip when the counter balance weights do not balance with a patient's weight.
Claims14
A therapeutic bed for immobilized patients, comprising:
- a motor-driven oscillating patient support platform mounted for longitudinal rotation about longitudinally extending axes;
- a counter balance keel means extending below the patient support platform for mounting counter balance weight means to minimize unbalancing of the bed due to a patient resting on the patient support platform;
- and
- a slip clutch means connecting the motor with the oscillating patient support platform and set to slip at a predetermined value when the counter balance weight means does not balance with the weight of a patient on the patient support platform.
A method of balancing a motor-driven oscillating therapeutic bed to a patient's weight comprising the steps of:
- setting a motor slip clutch connecting a drive motor to an oscillating patient support platform to slip at a predetermined value;
- mounting a keel having adjustable counter balance weight means extending below the patient support platform for minimizing imbalancing of the patient support platform and to prevent slippage of the slip clutch when the counter balance keel means balances with the weight of a patient on the patient support platform.
A method of balancing a motor-driven therapeutic bed having a slip clutch set to slip at a predetermined value connecting a drive motor to an oscillating patient support platform and a counter balance keel means extending below the patient support platform, comprising the steps of:
- positioning a patient on the oscillating patient support platform;
- and
- adjusting weight means on the counter balance keel means to minimize unbalancing of the patient support platform and to prevent slippage of the slip clutch when the counter balance keel means balances with the weight of a patient on the patient support platform.
