Dialysis machine

A peristaltic pump rotor comprising a body, an arm pivotally mounted to the body at an arm-body pivot point, the arm being movable between a deployed condition in which the arm is arranged, in use, to contact tubing in a peristaltic pump so as to effect pumping, and a retracted condition in which the arm is withdrawn from the tubing so that pumping is not effected; an actuator for effecting movement of the arm between the deployed and retracted conditions, the actuator comprising a first link pivotally mounted to the body at one end thereof and to a second link at the other end thereof, the second link being pivotally mounted to the first link at one end thereof and to the arm at the other end thereof at a point on the arm spaced from the arm-body pivot point; the links and pivot points being arranged such that the arm is retained in the deployed condition by the first and second links being arranged over center when the arm is in the deployed condition.

Peristaltic pump rotor

A respiratory muscle training device includes a chamber () containing a variable orifice valve assembly (). An inlet () is provided at a first side of the valve assembly permitting air to be inhaled into the chamber, and an outlet () is provided at a second side of the valve assembly permitting air that has passed through the valve assembly to be inhaled by a user. A pressure sensor () determines a pressure differential across the valve assembly. Means is provided for determining the opening area of the valve assembly, and control means () is provided for varying the orifice of the valve assembly in dependence upon a pressure differential determined by the pressure sensor and upon an opening area of the valve assembly.
