Abstract
A trigger arrangement for an infusion device is disclosed, the trigger arrangement being configured to trigger a bolus injection of the infusion device and including: a body having an outside surface, a haptic structure arranged on the outside surface or integrated into the outside surface, wherein the haptic structure includes a first end section and a second end section and wherein the haptic structure includes a haptic track extending from the first end section to the second end section, a touch sensitive sensor arrangement extending along the haptic track and configured to detect a sliding motion of an object along the haptic track.
Claims19
A trigger arrangement for an infusion device, the trigger arrangement being configured to trigger a bolus injection of the infusion device and comprising:
- a body having an outside surface,
- a haptic structure arranged on the outside surface or integrated into the outside surface, wherein the haptic structure comprises a first end section and a second end section, and wherein the haptic structure comprises a haptic and palpable track extending from the first end section to the second end section and terminating at the first end section and at the second end section, respectively,
- a touch sensitive sensor arrangement extending along the haptic and palpable track and configured to detect a sliding motion of an object along the haptic and palpable track, and
- an electronic controller connected to the touch sensitive sensor arrangement and connectable to a drive mechanism of the infusion device, wherein the electronic controller is operable to trigger the bolus injection when a predefined sliding pattern of the object along the haptic and palpable track is detected by the touch sensitive sensor arrangement,
- wherein the haptic and palpable track comprises a first track segment and a second track segment, the first track segment extends from the first end section to a surface segment, and the second track segment extends from the second end to the surface segment, and
- wherein the first track segment at least in sections extends along a first orientation, the second track segment at least in sections extends along a second orientation, and the first orientation extends at a predefined angle with regard to the second orientation.
An infusion device for administering a medicament to a patient, the infusion device comprising:
- a housing,
- a drive mechanism operably connectable to a container containing a medicament,
- an electronic controller configured to control operation of the drive mechanism for dispensing of a predefined amount of the medicament from the container,
- a trigger arrangement configured to trigger a bolus injection of the infusion device, the trigger arrangement comprising:
- a body having an outside surface,
- a haptic structure arranged on the outside surface or integrated into the outside surface, wherein the haptic structure comprises a first end section and a second end section, and wherein the haptic structure comprises a haptic and palpable track extending from the first end section to the second end section and terminating at the first end section and at the second end section, respectively, and
- a touch sensitive sensor arrangement extending along the haptic and palpable track and configured to detect a sliding motion of an object along the haptic and palpable track,
- wherein the body of the trigger arrangement is part of the housing or is connected to the housing and wherein the trigger arrangement is connected to the electronic controller, and
- wherein the electronic controller is connected to the touch sensitive sensor arrangement and connectable to the drive mechanism, wherein the electronic controller is operable to trigger the bolus injection when a predefined sliding pattern of the object along the haptic and palpable track is detected by the touch sensitive sensor arrangement,
- wherein the haptic and palpable track comprises a first track segment and a second track segment, the first track segment extends from the first end section to a surface segment, and the second track segment extends from the second end to the surface segment, and
- wherein the first track segment at least in sections extends along a first orientation, the second track segment at least in sections extends along a second orientation, and the first orientation extends at a predefined angle with regard to the second orientation.
