Embodiment Construction

[0017] in accordance with figure 1 and figure 2 The infusion set A is provided for administering a medical fluid 4 in the context of outpatient and / or inpatient infusion therapy. The infusion device A has a medical pump device 1 which can also be referred to as an elastomer infusion pump or a medical elastomer pump. The medical pump device 1 has an elastomer membrane 2 forming a pump volume 3 for receiving and delivering a medical fluid 4 . refer to figure 1 , the medical pump device 1 is shown in a filled state at least partially filled with a medical fluid 4 . In this state, the elastomer membrane 2 expands flexibly like a balloon due to the action of the medical fluid 4 . refer to figure 1 , the membrane 2 is illustrated with an exaggerated wall thickness for graphical reasons. In contrast, in the state not filled with medical fluid 4, the membrane 2 is relaxed, or at least elastically expanded to a lesser extent. For the purpose of filling the pump volume 3 or the ...

Abstract

The invention relates to an infusion assembly for administering a medical fluid. The known infusion arrangement has a medical pump apparatus which is in the form of a medical elastomer pump having a membrane, and said membrane serves for receiving and delivering the medical fluid. Moreover, the known infusion arrangement has an infusion line which is operatively connected to a pump volume of the membrane. The infusion line forms a main fluid channel for transferring the medical fluid from the pump volume to a patient access means. For the purpose of monitoring the functioning of the pump apparatus, the known infusion arrangement has a mechanical monitoring device which is operatively connected to the infusion line 8. The monitoring device 10 is configured for monitoring the functioning ofthe medical pump apparatus. The monitoring device has a differential pressure-measuring element operatively connected to the main fluid channel and is designed such that a differential pressure formedalong a channel portion of the main fluid channel is able to be detected by means of the differential pressure-measuring element and, in a manner dependent on the differential pressure, a delivery rate of the medical fluid along the main fluid channel is able to be indicated. The invention also relates to use in a medical infusion system.

Description

technical field [0001] The present invention relates to an infusion set for administering a medical fluid, the infusion set having a medical pump device having an elastomeric membrane forming a pump volume for receiving and delivering the medical fluid, wherein the elastomeric membrane is in The pump volume elastically expands in a filling state at least partially filled with medical fluid and thereby generates a delivery pressure on the pump volume; an infusion line, which is operatively connected to the pump volume at one end and is provided at the other end for a patient access device that is fluidly conductively connected and forms a primary fluid channel for transferring medical fluid from the pump volume to the patient access device; and a mechanical monitoring device that is operatively connected to the infusion line and configured for monitoring Operation of pump equipment. Background technique [0002] Such an infusion device is known from WO 2015 / 110387 A1 and is ...
