A miniaturised roller pump.

Abstract

A roller pump is described which is able to pump microlitre quantities of solution in either direction. It depends upon a caged roller bearing where the individual rollers press against silicon rubber tubing having an internal diameter of 0.5 mm. This assembly was housed in a cylindrical cavity shaped to produce a non-pulsatile flow. The pump is driven by a stepping motor to produce a constant flow rate. It is used to obtain small samples of bathing solution from near the surface of brain slices to monitor efflux of amino acids.

A new oral surgery teaching model.

An anatomical model for teaching the practical aspects of routine oral surgery in a clinical or laboratory environment, is described. Replaceable sections allow the model to be rapidly re-used so that successive students may practise procedures such as incisions, flap reflection, bone removal, tooth removal, apicectomy and suturing. Keeping the cost per procedure to a minimum was considered to be of fundamental importance and this has been achieved through the use of 'factory produced' replacement parts.
