Medical accessory pole clamp
First Claim
1. A combination of a parenteral solution delivery system and an acessory clamping device comprising a system housing having a first stationary clamping surface attached thereto, a cam pivotally mounted on a trunnion connected to said system housing and havind a moveable clamping surface, the stationary clamping surface and moveable clamping surface being positioned to constitute a clamping means when the clamp is in a clamping position, a spring means having one end connected to the trunion and the other end connected to the cam for biasing the cam to the clamping position, a lever means pivotally mounted on the trunion for pivotal movement in a clamp releasing direction and in an opposite clamping direction, the lever means being mounted for pivotal movement independent of the pivotal movement of the cam, the lever means being connected to a cam engaging means for engaging the cam and causing it to pivot with the lever when the lever is pivoted in a clamp releasing direction and for releasing the cam and permitting it to return to the clamping position as the lever is pivoted in the clamping direction.

Abstract
A mounting clamp particularly suited for mounting medical accessories on support poles comprises a stationary clamping surface which can be attached to an accessory housing. A cam is pivotly mounted on a trunnion connected to the stationary clamping surface has a spiral clamping surface, the stationary clamping surface and spiral clamping surface being positioned to constitute a clamping means when the clamp is in a clamping position. A spring means having one end connected to the trunnion and the other end connected to the cam is provided for biasing the cam to the clamping position. A lever pivotly mounted on the trunnion has a projection which engages the cam and causing it to pivot with the lever when the lever is pivoted to a clamp releasing position. The cam preferably has two spiral surfaces, one generated by a line parallel to the axis of rotation of the cam and the second cam surface by a line forming an angle with the axis of rotation of the cam. Two stationary surfaces preferably oppose the two cam surfaces, whereby the clamp bears on a total of four surfaces of a support pole when fully secured.
