Abstract

Abstract A self-operating traction system is disclosed. The system includes a supporting mechanism which is positioned above an orthopedic traction apparatus to support a lifting pulley above a traction weight. The supporting mechanism also supports a control pulley and a tie cleat within arms reach of a patient. A disabling cord rides on the lifting pulley and the control pulley, and is operatively attached to the traction weight. The patient pulls on the disabling cord to temporarily disable the traction weight and secures the disabling cord to the tie cleat to permanently disable the traction weight. The supporting mechanism has several structural features which permit it to be used for a variety of orthopedic traction applications.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 246 words
In bed-type traction apparatus including beds for supporting patients in lying attitudes, traction cords with first and second ends, traction weights respectively attached to the first ends of said traction cords for causing downward forces to be exerted on said traction cords and patient attaching means respectively fixed to the second ends of said traction cords for attaching said traction cords to patients who are supported by said beds, an improvement comprising a portable traction disabling system which includes: first and second vertical support means, said first vertical support means including means for selectively attaching and detaching said first vertical support means to, and from, the heads of said beds and said second vertical support means including means for selectively attaching, and detaching, said second vertical support means to and from, the feet of said beds; a horizontal member having horizontal-member mounting means located at the ends thereof for selectively attaching and detaching said horizontal support member to and from upper ends of said first and second vertical support means; a disabling cord means having first and second ends, said disabling-cord means first end being attachable to said bedtype traction apparatus, for disabling said downward forces caused by said weights in responSe to counterforces being applied to said disabling cord means at said disabling cord second end; and, a disabling cord guidance means mounted on said horizontal support for positioning said disabling cord''s second end within arms reach of patients who are supported on said beds.
Claim 2
Dependent Claim 246 words
In bed-type traction apparatus including beds for supporting patients in lying attitudes, traction cords with first and second ends, traction weights respectively attached to the first ends of said traction cords for causing downward forces to be exerted on said traction cords and patient attaching means respectively fixed to the second ends of said traction cords for attaching said traction cords to patients who are supported by said beds, an improvement comprising a portable traction disabling system which includes: first and second vertical support means, said first vertical support means including means for selectively attaching and detaching said first vertical support means to, and from, the heads of said beds and said second vertical support means including means for selectively attaching, and detaching, said second vertical support means to and from, the feet of said beds; a horizontal member having horizontal-member mounting means located at the ends thereof for selectively attaching and detaching said horizontal support member to and from upper ends of said first and second vertical support means; a disabling cord means having first and second ends, said disabling-cord means first end being attachable to said bedtype traction apparatus, for disabling said downward forces caused by said weights in responSe to counterforces being applied to said disabling cord means at said disabling cord second end; and, a disabling cord guidance means mounted on said horizontal support for positioning said disabling cord''s second end within arms reach of patients who are supported on said beds.
Claim 3
Dependent Claim 82 words
A traction weight disabling system as claimed in claim 1 wherein said disabling cord guidance means comprises: a lifting pulley means attached to said horizontal member at a location which is approximately over said traction weights for guiding said disabling-cord first end to said traction weight; a control pulley means attached to said horizontal member at a location which is approximately over said patient''s shoulders for guiding said disabling-cord second end to within arms reach of patients supported in said lying attitudes.
Claim 4
Dependent Claim 19 words
A traction weight disabling system as claimed in claim 2 wherein said horizontal member is an elongated rigid member.
Claim 5
Dependent Claim 42 words
A traction weight disabling system as claimed in claim 3 wherein said traction weight disabling system further comprises a tie cleat means attachable to said horizontal member at positions within arms reach of patients supported in said lying attitudes on said beds.
Claim 6
Dependent Claim 19 words
A traction weight disabling system as claimed in claim 3 wherein the length of said horizontal member is adjustable.
Claim 7
Dependent Claim 38 words
A traction weight disabling system as claimed in claim 3 wherein said control pulley includes an attachment means for selectively attaching said control pulley means to said horizontal member at a plurality of positions along said horizontal member.
Claim 8
Dependent Claim 27 words
A traction weight disabling system as claimed in claim 6 wherein said disabling cord guidance means further comprises guiding eyes which are supported on said horizontal member.
