Adjustable cervical traction assemblies for person support apparatuses
A cervical traction assembly for use with a patient support apparatus includes an adjustment carriage track member including a connecting bracket assembly that releasably connects to a mount support member of the patient support apparatus. The adjustment track member includes a track body including a pair of opposing sidewalls that are spaced-apart from each other to define an elongated channel therebetween. Each sidewall includes a guide track that extends along a length of the respective sidewall. A rope angle adjustment carriage is located within the channel. The rope angle adjustment carriage includes a first track engagement member that is received by one of the guide tracks of one of the sidewalls and a second track engagement member that is received by another of the guide tracks of another of the sidewalls. The first track engagement member has a locked configuration that inhibits movement of the rope angle adjustment carriage.
1. A cervical traction assembly for use with a patient support apparatus, the cervical traction assembly comprising:
an adjustment carriage track member that mounts to a mount support member of a forward column assembly of the patient support apparatus, the adjustment carriage track member comprising a connecting bracket assembly that releasably connects to the mount support member, the adjustment carriage track member comprising a track body comprising a pair of opposing sidewalls that are spaced-apart from each other to define an elongated channel therebetween, each sidewall including a guide track that extends along a length of the respective sidewall; and
a rope angle adjustment carriage that is located within the elongated channel, the rope angle adjustment carriage comprising a first track engagement member received by one of the guide tracks of one of the sidewalls and a second track engagement member received by another of the guide tracks of another of the sidewalls;
wherein the first track engagement member has a locked configuration that inhibits movement of the rope angle adjustment carriage along the elongated channel and an unlocked configuration that allows movement of the rope angle adjustment carriage along the elongated channel.
2. The cervical traction assembly of claim 1 , wherein the one of the guide tracks is a first guide track, the first guide track having a first side and second side opposing the first side, the second side having undulating peaks and valleys that provide the first guide track with regions of decreased and increased width.
3. The cervical traction assembly of claim 2 , wherein the first track engagement member comprises:
a body; and
an engagement projection that extends a width of the body;
wherein the first track engagement member is moveable between the locked configuration with the engagement projection received within one of the valleys of the first guide track to prevent movement of the first track engagement member along the first guide track and the unlocked configuration with the engagement projection removed from the one of the valleys of the first guide track to allow movement of the first track engagement member along the first guide track.
4. The cervical traction assembly of claim 3 , wherein the one of the guide tracks is a second guide track, the second guide track having a first side and second side opposing the first side of the second guide track, the second side of the second guide track having undulating peaks and valleys that provide the second guide track with regions of decreased and increased width.
5. The cervical traction assembly of claim 4 , wherein the second track engagement member comprises:
a body; and
an engagement projection that extends a width of the body;
wherein the second track engagement member is moveable between a locked configuration with the engagement projection of the second track engagement member received within one of the valleys of the second guide track to prevent movement of the second track engagement member along the second guide track and an unlocked configuration with the engagement projection of the second track engagement member removed from the one of the valleys of the second guide track to allow movement of the second track engagement member along the second guide track.
6. The cervical traction assembly of claim 5 , wherein the first track engagement member and the second track engagement member can be depressed to their respective unlocked configurations.
7. The cervical traction assembly of claim 3 , wherein the body of the first track engagement member includes a recessed region that engages an edge of the first guide track with the first track engagement member in the locked configuration.
8. The cervical traction assembly of claim 1 , wherein the rope angle adjustment carriage has a rope pass-through opening.
