Cervical immobilization device
A cervical immobilization device is disclosed and includes at least one and, preferably, at least two opposite arms that can be folded between a flat and an upright position to engage and support a patient's head. A reversible actuating device folds the arms to the supporting position, and can lock the arms in the folded supporting position. Alternatively, a locking device for locking the position of the arms in the folded supporting position can be provided. The reversible actuating device can be coupled to the arms for folding the arms to an upright position symmetrically and uniformly. In one embodiment, the reversible actuating device is a flexible member that passes around a guide to a position which can be gripped by the user.
1. A cervical immobilization device, comprising:
a base having two opposite ends, a front edge, and a rear edge;
a cervical immobilizing member coupled to said base and including (i) a center portion and (ii) at least two opposite movable arms with each of said movable arms being foldable between a first position and a second folded position for engaging a patient's head, each of said movable arms having:
a pivotal coupling between an inner edge of each of said movable arms and said center portion and
an outer edge facing outward toward a respective one of said opposite ends of said base; and
a reversible actuating device, said reversible actuating device is a flexible member, said flexible member has at least two flexible leg members, said reversible actuating device slides said outer edge of each of said movable arms to said second folded position.
2. The cervical immobilization device of claim 1 , wherein said reversible actuating device both folds and unfolds said movable arms.
3. The cervical immobilization device of claim 1 , wherein said reversible actuating device includes more than one piece.
4. The cervical immobilization device of claim 1 , wherein said flexible leg members include a pushing means.
5. The cervical immobilization device of claim 1 , wherein said reversible actuating device includes a lock.
6. The cervical immobilization device of claim 5 , wherein said lock is a post and hole mechanism.
7. The cervical immobilization device of claim 1 , further comprising a guide member for guiding said reversible actuating device.
8. The cervical immobilization device of claim 7 , wherein said guide member includes an elongated slot through which said reversible actuating device passes, whereby pulling said reversible actuating device through said slot pulls said movable arms toward said center portion to said second folded position.
9. A cervical immobilization device, comprising:
a base having two opposite ends, a front edge, and a rear edge;
a cervical immobilizing member coupled to said base and including (i) a center portion and (ii) at least two opposite movable arms with each of said movable arms being foldable between a first position and a second folded position for engaging a patient's head, each of said movable arms having:
a pivotal coupling between an inner edge of each of said movable arms and said center portion and
an outer edge facing outward toward a respective one of said opposite ends of said base; and
a reversible actuating device, said reversible actuating device includes a rod attached to a first end of at least two flexible members, a second end of said flexible members is fixed to one of said movable arms, said rod rotates to wind said flexible members, said reversible actuating device slides said outer edge of each of said movable arms to said second folded position.
10. The cervical immobilization device of claim 9 , wherein said reversible actuating device both folds and unfolds said movable arms.
11. The cervical immobilization device of claim 9 , wherein said reversible actuating device includes more than one piece.
12. The cervical immobilization device of claim 9 , wherein said flexible members are stiff and include a pushing means.
13. The cervical immobilization device of claim 9 , wherein said reversible actuating device includes a lock.
14. The cervical immobilization device of claim 9 , wherein said lock is a post and hole mechanism.
15. The cervical immobilization device of claim 9 , further comprising a guide member for guiding said reversible actuating device.
16. The cervical immobilization device of claim 15 , wherein said guide member includes an elongated slot through which said reversible actuating device passes, whereby pulling said reversible actuating device through said slot pulls said movable arms toward said center portion to said second folded position.
