1. A system for delivery of a therapeutic fluid to a body of a patient and/or for sensing of a bodily analyte comprising:
- a device suitable for at least one of delivery of the therapeutic fluid and sensing of the bodily analyte, the device including a skin adherable portion having a first opening;
a subcutaneously insertable element and a penetrating member configured to be protracted through the opening to penetrate a skin of the patient; and
an insertion apparatus removably coupleable to the skin adherable portion of the device, the insertion apparatus comprising;
a housing adapted for accommodating therein at least one penetrating cartridge which includes the subcutaneously insertable element and the penetrating member;
a displacement mechanism configured to protract the penetrating cartridge towards the body of the patient;
wherein protraction of the penetrating cartridge results in penetration of the skin by the penetrating member and insertion of at least the subcutaneously insertable element into the body of the patient; and
at least one pain reduction mechanism for alleviating pain associated with the penetrating of the skin by the subcutaneously insertable element and the penetrating member, the at least one pain reduction mechanism comprising;
a first portion provided by the insertion apparatus; and
receiving means provided by the skin adherable portion for receiving the first portion and allowing the first portion to protrude through the skin adherable portion when the insertion apparatus is coupled to the skin adherable portion.
