Abstract
A hand operated medical pump is described including: at least one fluid inlet; at least one fluid outlet; a flexible pump bulb defining a pumping chamber which forms at least part of a pumping flow pathway; at least one directional valve which allows flow of fluid in a direction from the at least one inlet to the at least one outlet, but inhibits flow of fluid in a direction from the at least one outlet to the at least one inlet; and a bypass flow pathway from the at least one inlet to the at least one outlet which by-passes the at least one directional valve; and wherein the bypass flow pathway extends through the pump bulb.
