Embodiment Construction
[0031] figure 1 The infusion device 1 is shown schematically in the form of a peristaltic (volumetric) infusion pump. The infusion device 1 comprises a first housing element in the form of a housing 10 having a front face 100 and a receptacle 101 arranged on the front face 100 . The receiving portion 101 is shaped as a receiving opening and is configured to receive the pump module 20 of the (disposable) tube set 2 .
[0032] Attached to the housing 10 is a second housing element in the form of a door 11 pivotable relative to the housing 10 about a pivot axis P for access to and arrangement on the front face 100 . The upper receiving part 101. By pivoting the door 11 away from the front face 100 , the receptacle 101 can be reached for inserting the pump module 2 into the receptacle 101 or for removing the pump module 2 from the receptacle 101 . During operation of the infusion device 1 , the door 11 is closed so that the tube set 2 is firmly held on the housing 10 .

An infusion device (1) for acting on a tubing set (2) to deliver a medical fluid through the tubing set (2), the infusion device (1) comprising a first housing element (10) and a second housing The body element (11), the first housing element (10) is configured to receive the tube sections (200, 201) of the tube group (2), and the second housing element (11) can be relative to the first housing element ( 10) Move such that in the closed position of the second housing element (11), the first housing element (10) and the second housing element (11) are configured to receive the pipe sections (200, 201) between each other between. The sensor device (3) is arranged on the first housing element (10) and has a sensor element (30) for measuring the force on the pipe sections (200, 201) of the pipe stack (2). In this context, the sensor device (3) is arranged to be elastically displaceable on the first housing element (10), wherein the sensor device (3) is supported via at least one spring element (33) on the second housing element (10). on a housing element (10). In this way an infusion device is obtained which makes the compression of the tube section between the sensor element and the movable housing element less prone to variations, thereby potentially reducing the need for calibrating the infusion device. workload and increases the reliability of the pressure measurement on the pipe section.
Description
technical field [0001] The invention relates to an infusion device. Background technique [0002] Such an infusion device is intended to act on a tubing set for conveying a medical fluid through the tubing set. Such an infusion device can be configured, for example, as a peristaltic (volumetric) infusion pump with a peristaltic pump mechanism, which can act, for example, on a flexible wall section of a pump module, as for example in US 2012 / described in 0207635A1. [0003] The infusion device comprises a first housing element configured to receive a tubing section of the tubing set and a second housing element that is movable relative to the first housing element such that the second housing In the closed position of the body element, the first housing element and the second housing element are configured to receive the pipe section between each other. A sensor device is arranged on the first housing element, and the sensor device comprises a sensor element for measuring...
