Abstract
Abstract A device for holding a cannula connected to a vein or artery in the arm of a kidney machine patient comprising a handgrip having a longitudinal brace extending therefrom, the longitudinal brace including slidable support means for a clamp. The clamp having a bight portion peculiarly adapted to hold but not compress the cannula, and a cable extending from the clamp to the handle whereby the patient may actuate the clamp by use of the hand of the arm in which the cannula is implanted. In another embodiment compressors are provided to stop the flow of blood in a vein in the arm of the patient.
