ABSTRACT:
A device for administering liquid in a device for the parenteral administration of liquid, comprising a pump which conveys the liquid through an elastic tube to the patient, the entry of air into the tube is prevented by the provision of a valve (20) in the tube downstream of the pump. This valve opens in the patient's direction under a pressure of such magnitude that the pressure inside the tube upstream of the valve is at least approximately as great as the external air pressure. The check valve provided may be used together with a pump as well as under mere gravity feeding.
