Inserter having two springs
First Claim
1. An inserter for a medical device comprising:
- a stationary part being stationary in relation to the patient during insertion and resting against the patient'"'"'s skin;
a carrier body having a forward and a retracted position relative to the stationary part;
a needle hub connected with a penetrating member;
a first elastic element and a second elastic element configured such that activation of the first elastic element causes a penetrating member to be inserted sub- or transcutaneously into the skin of a patient, and the second elastic element causes the penetrating member to be retracted from the skin of the patient, the first elastic element is in an unloaded state before activation and upon activation, the first elastic element energizes the second elastic element;
a first locking member configured to releasably lock the carrier body in the retracted position;
a first release member configured to unlock the carrier body from the retracted position;
a second locking member configured to releasably lock the needle hub in a forward position relative to the carrier body;
a second release member configured to unlock the needle hub from the needle hub forward position, the needle hub being movable relative to the carrier body; and
an activator configured to activate the first elastic element.

Abstract
The invention relates to an inserter for a medical device e.g. an infusion set or the like for intermittent or continuous administration of a therapeutical substance, such as e.g. insulin. The inserter comprises a needle hub comprising an insertion needle and two elastic elements assuring automatic insertion and automatic retraction of the insertion needle. Activation of the first elastic element (11) cause a penetrating member (6A) to be inserted sub- or transcutaneously into the skin of a patient, and the second elastic element (12) cause the penetrating member (6A) to be retracted from the skin of the patient. The first elastic element (11) is in an unloaded state before activation and upon activation the first elastic element (11) energizes the second elastic element (12).
