Abstract
Abstract A back traction and relaxing system is disclosed adapted to be used on a patient lying on a supporting surface such as a hospital bed or the like. A frame is secured to the frame of the bed and extends over the patient. A first pulley is mounted on the frame approximately over the patient's waist and has a cable extending therearound and downwardly therefrom towards the patient. A gear motor is connected to the cable for longitudinally moving the cable relative to the pulley. A knee and ankle supporting mechanism is secured to the lower end of the cable and comprises a transversely extending knee support adapted to fit beneath the patient's knees. An elongated member is secured to the knee support and extends therefrom towards the patient's feet. A transversely extending ankle support is secured to the end of the elongated member and is adapted to be positioned over the patient's ankles. Upward movement of the cable by the gear motor causes the knee and ankle supporting mechanism to move upwardly thereby causing the patient's buttocks to be raised slightly from the bed thereby relaxing the patient's lower back area. The knee support pulls upwardly on the underside of the patient's knees while the ankle support prevents the patient's legs from disengaging from the knee and ankle supporting mechanism.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
188 words
A back traction and relaxing system for use on a patient lying on a supporting surface, comprising, a frame means positioned over the patient, a first pulley mounted on said frame means approximately over the patient's waist, a cable extending around said first pulley and downwardly therefrom towards the patient, a knee and ankle supporting mechanism secured to one end of said cable, power means operatively connected to said cable for longitudinally moving said cable whereby said knee and ankle supporting mechanism may be selectively raised and lowered, said knee and ankle supporting mechanism comprising a first transversely extending support secured at its center length to said one end of said cable adapted to be positioned beneath the patient's knees, an elongated member secured to the center length of said first support and extending therefrom towards the patient's feet, a second transversely extending support secured to said elongated member adapted to be positioned over the top of the patient's ankles whereby predetermined upward movement of said knee and ankle supporting mechanism, by said power means, will cause the patient's buttocks to be slightly raised from the supporting surface.
Claim 2
Dependent Claim
188 words
A back traction and relaxing system for use on a patient lying on a supporting surface, comprising, a frame means positioned over the patient, a first pulley mounted on said frame means approximately over the patient's waist, a cable extending around said first pulley and downwardly therefrom towards the patient, a knee and ankle supporting mechanism secured to one end of said cable, power means operatively connected to said cable for longitudinally moving said cable whereby said knee and ankle supporting mechanism may be selectively raised and lowered, said knee and ankle supporting mechanism comprising a first transversely extending support secured at its center length to said one end of said cable adapted to be positioned beneath the patient's knees, an elongated member secured to the center length of said first support and extending therefrom towards the patient's feet, a second transversely extending support secured to said elongated member adapted to be positioned over the top of the patient's ankles whereby predetermined upward movement of said knee and ankle supporting mechanism, by said power means, will cause the patient's buttocks to be slightly raised from the supporting surface.
Claim 3
Dependent Claim
17 words
The system of claim 1 wherein said second support is longitudinally adjustably mounted on said elongated member.
Claim 4
Dependent Claim
34 words
The system of claim 1 wherein said first and second supports have upper and lower ends, the lower end of said first support being padded, the upper end of said second support being padded.
Claim 5
Dependent Claim
12 words
The system of claim 1 wherein said frame means is length adjustable.
Claim 6
Dependent Claim

The system of claim 1 wherein a control means is operatively connected to said power means for controlling the operation thereof, said control means being located adjacent the patient.
Claim 7
Dependent Claim
23 words
The system of claim 1 wherein said supporting surface comprises a bed, said frame means being secured to and supported by said bed.
Claim 8
Independent Claim
113 words
The method of relieving back pain in a person, comprising the steps of: (a) positioning the person in a supine position on a supporting surface; (b) placing a support beneath the person's knees and over the person's ankles so as to prevent the patient's feet from raising upwardly as upward pressure is applied to said support; (c) raising the support and the patient's knees, relative to said supporting surface, until the patient's buttocks have moved out of substantial engagement with said supporting surface so that the person's back is placed in flexion traction; and (d) lowering the support, after a predetermined length of time, to remove the flexion traction from the person's back.
