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.
