Cam follower

A counterbalance hinge assembly includes a cam and compression device that counterbalances a weight of a door or a ramp. The compression device biases against a rotation of the door or ramp. The downward movement of the door or ramp drives cam followers in angled slots or cam surfaces of the cam. The angled slots or cam surfaces include varying angles of incline to correspond to varying torque forces of the door or ramp during the opening or closing movement of the door or ramp.

An intravenous (IV) fluid bag hanger is described for use in an ambulance or other emergency vehicle. A handle is configured to pivot or rotate between storage and deployed positions. The fluid bag hanger includes a double-sided carabiner. The double-sided carabiner includes a first holding region and a second holding region to hold one or more intravenous fluid bags. The double-sided carabiner forms a hub between the first holding region and the second holding region. An axle of the handle rotates in the hub.
