摘要：
Disclosed is a hand operated medical pump. The medical pump includes at least one fluid inlet (120, 140), at least one fluid outlet, a flexible pump bulb (340), at least one directional valve (356, 366) and a bypass flow pathway. The flexible pump bulb defines a pumping chamber which forms at least part of a pumping flow pathway. The at least one directional valve (356, 366) which allows flow of fluid in a direction from the at least one inlet (120, 140) 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 (120, 140). The bypass flow pathway from the at least one inlet (120, 140) to the at least one outlet bypasses the at least one directional valve (356, 366). The bypass flow pathway extends through the pump bulb (340).
