Abstract

In various embodiments, a therapeutic bed is provided which comprises a base frame, a patient support frame having a support for supporting a patient in a prone position, said patient support frame being rotationally mounted on the base frame, such that the patient support frame is capable of rotating with respect to the base frame for repositioning said patient between a supine position and a prone position. In various embodiments, the therapeutic bed includes a control member having an engaged, disengaged, and neutral position. In such embodiments, each of the engaged disengaged, and neutral position controls at least one of an electrical rotation of the bed and a mechanical rotation of the bed.

Claims

1. A therapeutic bed comprising:

a base frame;

a patient support frame rotatably mounted on the base frame;

a drive system; and

a locking member, wherein;

the patient support frame is configured for automatic rotation by the drive system and for manual rotation by a person;

the locking member is configured for placement in a locked position, an unlocked position, and a neutral position, wherein;

automatic and manual rotation of the patient support frame are restricted when the locking member is in the locked position;

automatic rotation of the patient support frame is restricted and manual rotation is allowed when the locking member is in the neutral position; and

automatic and manual rotation of the patient support frame are allowed when the locking member is in an unlocked position.

2. The therapeutic bed of claim 1, further comprising a position detector configured to detect whether the locking member is in the locked position, the unlocked position, or the neutral position.

3. The therapeutic bed of claim 2, further comprising a control system configured to control the drive system, wherein:

the position detector is configured to transmit a signal to the control system; and

the signal indicates whether the locking member is in the locked position, the unlocked position, or the neutral position.

4. The therapeutic bed of claim 1, wherein the locking member comprises a detent configured to impede accidental movement of the locking member between the locked position, the unlocked position, and the neutral position.

5. The therapeutic bed of claim 1, wherein:

the patient support frame is coupled to a ring comprising a hole; and

the locking member engages the hole when the locking member is in the locked position.

6. The therapeutic bed of claim 1, wherein the drive system comprises a motor.

7. The therapeutic bed of claim 6, wherein the motor is a stepper motor.

8. The therapeutic bed of claim 6, wherein the motor engages a belt.

9. The therapeutic bed of claim 1, wherein the patient support frame is configured for automatic or manual rotation from a supine position to a prone position.

10. The therapeutic bed of claim 1, further comprising a quick release mechanism configured to disengage the drive system from the patient support frame.

11. The therapeutic bed of claim 10, wherein:

the drive system comprises a motor and a belt; and

the quick release mechanism is configured to adjust a tension on the belt.
