Safety device for an infusion pump
First Claim
1. A safety device (20, 30) for an infusion pump (1) with which liquids can be delivered via an infusion tube (10), characterized in that the infusion pump (1) can move the infusion tube (10) into a closed position, in that the pump mechanism, in the closed position of the infusion tube (10), can change the pressure conditions in the closed-off segment (50), and, with the aid of a sensor (52), the pressure variations in said closed-off segment (50) can be measured directly or indirectly, so that functions of the infusion pump (1) and of the infusion tube (10) can be checked with the measured values.

Abstract
A throughflow locking element (20, 30) for an infusion pump receives a flexible infusion tube and is provided with a clamp valve (20; 21, 22). The clamp valve (20) has two openings (23, 24) through which the flexible infusion tube can be introduced. Said clamp valve has a lockable closed position and an open position in relation to the throughflow through the flexible infusion tube and can be inserted in a holder (30) in the infusion pump in a positive fit. A drive element (31) is provided in the infusion pump, enabling the clamp valve (20) to be moved from the open position into the lockable closed position and vice-versa, whereby the throughflow locking element (20) is sealed in a secure manner prior to removal of the flexible infusion tube from the infusion pump.
