Problems solved by technology
It must be taken into account here that, in general, false alarms should be avoided during the administration of a bolus since, naturally, the administration of a bolus will lead to an increase in the infusion line due to the presence of an extra volume of fluid in the infusion line. increased pressure

Embodiment Construction
[0037] figure 1 An embodiment of an infusion device 1 in the form of a syringe pump is shown, having a housing 10 and a receptacle 11 arranged on the housing 10 for receiving a syringe 2 in the receptacle 11 .
[0038] The syringe 2 comprises a cylindrical tube 20 containing a medical fluid, such as a drug, to be infused into the patient 4 when the syringe 2 is mounted on the infusion set 1 . The cylindrical tube 20 is connected via a connector 200 to an infusion line 3 which can extend from the syringe 2 towards the patient 4 for infusing the patient 4 with a medical fluid.
[0039] In order to mount the syringe 2 on the receptacle 11 of the infusion set 1 , the cylindrical tube 20 of the syringe 2 is seated in the receptacle 11 and mechanically connected to the housing 10 by means of fixing means 110 . By means of fixing means 110 , for example constituted by releasable clamping elements, the cylindrical tube 20 is fastened within the receptacle 11 such that the cylindrica...

The invention provides an infusion device constituted to detect an abnormal condition during bolus injection. The infusion device (1) for administering a medical fluid to a patient (4) comprises a pumping mechanism (12) for pumping a medical fluid through an infusion line (3) towards a patient (4), a sensor device (120) for measuring a measurement value indicative of a pressure in the infusion line (3), and a control device (13) being constituted to control the pumping mechanism (12) for injecting a bolus of medical fluid into the infusion line (3). Herein, the control device (13) is constituted to determine, dependent on an injection of a bolus into the infusion line (3), a control parameter taking a change in pressure during injection of the bolus into account and to derive, from the control parameter, the presence of an abnormal condition during the injection of the bolus. In this way an infusion device is provided which in a reliable manner allows for the detection of an abnormal condition during the administration of a bolus.
Description
technical field [0001] The invention relates to an infusion set for administering a medical fluid to a patient according to the preamble of claim 1 and to a method for operating the infusion set. Background technique [0002] The infusion set includes a pumping mechanism for pumping the medical fluid through the infusion line to pump the medical fluid to the patient. The sensor means, in particular a force sensor, is used to measure a measurement indicative of the pressure in the infusion line, and the control means is configured to control the pumping mechanism for injecting a dose into the infusion line medical fluid. [0003] It should be noted that such an infusion device may consist, for example, of a syringe pump comprising a syringe to which an infusion line is connected and on which a pumping mechanism in the form of a pusher device acts to inject the The medical fluid is delivered from the syringe through the infusion line to the patient. However, the infusion de...
