Insertion device and method for inserting a subcutaneously insertable element into body
First Claim
1. An insertion device for use with a device for delivery of a therapeutic fluid into a body of a patient and/or for sensing of a bodily analyte, the insertion device comprising:
- a housing having accommodated therein;
at least one penetrating cartridge provided with a penetrating member and a subcutaneously insertable element;
a displacement mechanism which upon actuation is capable of protracting said penetrating cartridge towards the device for delivery and/or sensing and inserting the subcutaneously insertable element into a subcutaneous compartment of the body, the displacement mechanism being movable from a first position in which the displacement mechanism is prevented from actuation to a second position in which the displacement mechanism can be actuated; and
a safety means for allowing the displacement mechanism to move from the first position to the second position for actuation only when the insertion device has been placed in an appropriate position on the device for delivery and/or sensing;
wherein said insertion device is suitable for inserting the subcutaneously insertable element into the subcutaneous compartment of the body via an opening provided in the device for delivery and/or sensing and said insertion device allows evacuation of the penetrating member from the subcutaneous compartment via the opening.

Abstract
An insertion device for a fluid delivery device for delivering a therapeutic fluid to a body of a patient and/or for sensing of a bodily analyte is disclosed. The insertion device includes a housing and accommodated therein at least one penetrating cartridge provided with a penetrating member and with a subcutaneously insertable element; The insertion device is provided with a displacement mechanism which upon actuation is capable of protracting the penetrating cartridge towards the said device for delivery and/or sensing, wherein said protracting results in inserting of the penetrating cartridge into subcutaneous compartment of the body via an opening provided at the said device for delivery and/or sensing and said insertion device allows evacuation of the penetrating member from the subcutaneous compartment via the said opening.

28. A method for delivering a therapeutic fluid to a subcutaneous compartment in a body of a patient and/or for sensing of a bodily analyte, said method comprising the steps of:
-
providing a device for delivery of the therapeutic fluid and/or for sensing the bodily analyte; providing an insertion device comprising;
at least one penetrating cartridge having a penetrating member and a subcutaneously insertable element;
said insertion device further comprising a displacement mechanism and a safety means for allowing the displacement mechanism to actuate only when the insertion device has been placed in an appropriate position on the device and the displacement mechanism has been moved from a first position in which the displacement mechanism is prevented from actuation to a second position in which the displacement mechanism can be actuated;placing the insertion device on the device for delivery and/or sensing in the appropriate position to disable the safety means; after the insertion device has been placed on the device for delivery and/or sensing in the appropriate position, moving the displacement mechanism of the insertion device from the first position to the second position; actuating the displacement mechanism at the second position thereby protracting the penetrating cartridge by the displacement mechanism towards the body of the patient so as to insert the subcutaneously insertable element into the subcutaneous compartment via an opening provided at the device for delivery and/or for sensing; removing the penetrating member from the subcutaneous compartment while allowing the subcutaneously insertable element to remain in the subcutaneous compartment; and delivering the therapeutic fluid to the subcutaneous compartment through the subcutaneously insertable element and/or sensing the bodily analyte. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35)
