Abstract
A therapeutic treatment table having a lifting mechanism to allow lowering of the therapeutic treatment table close to the ground support surface and having a releasable connecting means to automatically connect or release the oscillating means from the therapeutic treatment table and an adjusting means to vary the degree of oscillation of the therapeutic treatment table.
Claims13
A therapeutic bed apparatus having an oscillatory patient support platform mounted thereto for rotation about the longitudinally extending axis thereof comprising:
- reciprocating drive means for controlled oscillation of the patient support platform about the longitudinally extending axis thereof;
- first pivot means spaced from the longitudinally extending axis of said patient support platform and connected with said reciprocating drive means for oscillating said patient support platform;
- said first pivot means having means for selectively changing the position at which said reciprocating drive means is connected to said patient support platform relative to the longitudinally extending axis thereof to vary the arc of oscillation of said patient support platform;
- and
- second pivot means eccentrically mounted upon said first pivot means for pivotally engaging said reciprocating drive means.
A therapeutic bed comprising:
- a patient support platform;
- reciprocating drive means pivotally connected to said patient support platform for oscillating said patient support platform about the longitudinal axis thereof;
- means spaced from the longitudinal axis of said patient support platform having a pivot means eccentrically mounted thereto for changing the point at which said reciprocating drive means is connected to said patient support platform relative to the longitudinal axis of said patient support platform to selectively vary the arc in which said patient support platform oscillates.
A therapeutic bed apparatus for immobilized patients having an oscillating patient support platform, comprising:
- a generally planar patient support platform having first and second support surfaces mounted for oscillating movement on an undercarriage;
- said first support surface being pivotally mounted relative to said second support surface to provide an inclined surface for a patient;
- and
- locking means operable responsive to pivoting of the first support surface to an inclined position to lock the patient support surface with the undercarriage to prevent oscillation when the first support surface is pivoted to the inclined position.
