Abstract
Abstract A rollover bed having a pallet with a pair of central hinge points to allow mid-body flexing and knee joint flexing of a patient supported by the pallet is capable of maintaining constant angular traction on the patient while the pallet is flexed to angles which are comfortable to the patient. The bed also maintains the constant angular traction on the patient during the operation of turning the patient over.

Total Claims: 15
Claim 1
Independent Claim
313 words
An apparatus for supporting a patient and maintaining constant traction on the patient, said apparatus comprising in combination: (a) an undercarriage having first and second ends; (b) first and second end members attached to the first and second ends of said undercarriage; (c) first pallet means for supporting a patient, said first pallet means having first and second ends thereof and also including first and second sections, said first and second sections being hingeably connected; (d) first hinge means for hingeably connecting said first and second sections; (e) first pallet support means connected to said first end member for supporting the first end of said first pallet means; (f) second pallet support means connected to said second end member for supporting the second end of said first pallet means; (g) first adjustable support means for adjustably supporting and controlling the height of the hinged portions of said first pallet means; (h) traction means for maintaining constant tension at a constant angle on a portion of the patient's body, said traction means including i. a traction cord being first end and also having a second end for connection to a part of the patient's body, ii. means connected to the second end of said traction cord for maintaining a constant tension in said traction cord, iii. cord support means rigidly connected to said first end support means, said cord support means maintaining a portion of said traction cord in fixed relationship to said second section of said first pallet means during pivotry of said first and second sections of said first pallet means about said first hinged means, whereby the body of the patient can be flexed by raising and lowering the hinged portion of said flexed first patient support means by means of said first adjustable support means without significantly altering either the traction tension or angle of application thereof to the patient.
Claim 2
Independent Claim
313 words
An apparatus for supporting a patient and maintaining constant traction on the patient, said apparatus comprising in combination: (a) an undercarriage having first and second ends; (b) first and second end members attached to the first and second ends of said undercarriage; (c) first pallet means for supporting a patient, said first pallet means having first and second ends thereof and also including first and second sections, said first and second sections being hingeably connected; (d) first hinge means for hingeably connecting said first and second sections; (e) first pallet support means connected to said first end member for supporting the first end of said first pallet means; (f) second pallet support means connected to said second end member for supporting the second end of said first pallet means; (g) first adjustable support means for adjustably supporting and controlling the height of the hinged portions of said first pallet means; (h) traction means for maintaining constant tension at a constant angle on a portion of the patient's body, said traction means including i. a traction cord being first end and also having a second end for connection to a part of the patient's body, ii. means connected to the second end of said traction cord for maintaining a constant tension in said traction cord, iii. cord support means rigidly connected to said first end support means, said cord support means maintaining a portion of said traction cord in fixed relationship to said second section of said first pallet means during pivotry of said first and second sections of said first pallet means about said first hinged means, whereby the body of the patient can be flexed by raising and lowering the hinged portion of said flexed first patient support means by means of said first adjustable support means without significantly altering either the traction tension or angle of application thereof to the patient.
Claim 3
Dependent Claim
36 words
The apparatus of claim 1 wherein said first pallet means is pivotally supported by said first and second pallet support means to permit rotation of said first pallet about a longitudinal axis of said pallet means.
Claim 4
Dependent Claim
29 words
The apparatus of claim 2 wherein first pallet support means includes a rollover hoop assembly having a first cross bar for supporting a first end of first pallet means.
Claim 5
Dependent Claim
35 words
The apparatus of claim 3 wherein said second pallet support means includes a pivotal connecting means rigidly attached to the second end of said first pallet means and pivotally connected to said second end member.
Claim 6
Dependent Claim
18 words
The apparatus of claim 4 wherein said cord supporting means is rigidly connected to said pivotal connecting means.
Claim 7
Dependent Claim
28 words
The apparatus of claim 5 wherein said pivotal connecting means includes a trunnion rigidly connected to the second end of said first pallet means, said trunnion being tubular.
Claim 8
Dependent Claim
50 words
The apparatus of claim 6 wherein said trunnion is parallel to the plane of the second section of said first pallet means, and wherein said pivotal connecting means includes a bearing means through which said trunnion extends, said trunnion rotating in said bearing means as said first pallet means rotates.
Claim 9
Dependent Claim
94 words
The apparatus of claim 7 wherein said cord supporting means includes a first pulley over which said traction cord passes and from which said traction cord extends to a part of the patient's body to which traction is applied, said cord supporting means further including a pulley support member rigidly attached to said trunnion, said first pulley being supported a predetermined distance from a longitudinal axis of said trunnion, whereby traction is maintained on the patient at a predetermined angle with respect to the plane of the second section of said first pallet means.
Claim 10
Dependent Claim
55 words
The apparatus of claim 8 wherein said traction cord extends from said first pulley to a second pulley rigidly connected to said trunnion through a hole through said trunnion, over a third pulley pivotally supported by said trunnion to a traction weight, whereby a substantially constant traction tension force is maintained in said traction cord.
Claim 11
Dependent Claim
112 words
The apparatus of claim 5 wherein said first adjustable support means includes a first hydraulic cylinder attached to said undercarriage and a hydraulic pump system for actuating said first hydraulic cylinder, said first hydraulic cylinder having a moveable rod, said first adjustable support means further including means connected to said moveable cylinder for engaging a point of said first pallet means disposed between said first and second ends of said first pallet means to effect raising and lowering the midportion of said first pallet means, causing pivoting of said first and second sections of said first pallet means about said first hinge means in response to operation of said hydraulic pump system.
Claim 12
Dependent Claim
32 words
The apparatus of claim 10 further including second hinge means, said first section of said first pallet means further including first and second subsections pivotally connected together by said second hinge means.
Claim 13
Dependent Claim
30 words
The apparatus of claim 11 further including second adjustable support means for adjustably supporting and controlling the height of a portion of said first pallet means adjacent second hinge means.
Claim 14
Dependent Claim
32 words
The apparatus of claim 5 further including means for adjusting the height of said pivotal connecting means, whereby the second end of said first pallet means can be controllably raised or lowered.
Claim 15
Dependent Claim
93 words
The apparatus of claim 9 wherein said pivotal connecting means further includes means for rigid attachment to an auxiliary pallet means, and wherein said rollover hoop includes a second cross bar for supporting the opposite end of said auxiliary pallet means, said first end of said auxiliary pallet including a pair of separable frame members which can be moved apart to allow said traction cord to pass between the separable frame members, whereby said auxiliary pallet means can be rigidly connected to said pivotal connecting means without interrupting traction applied to the patient.
