An inserter system comprising:
- a medical device and an inserter device for subcutaneously inserting at least a portion of the medical device,
- the medical device including an antimicrobial coating, the medical device comprising:
- 1) a port site having a cavity with the antimicrobial coating positioned on the cavity, the port site including a plurality of outer surfaces and a plurality of inner surfaces, and 2) a subcutaneous part, including a plurality of outer surfaces and a plurality of inner surfaces, the subcutaneous part being securable to the port site, wherein the subcutaneous part includes a body part having a ribbed portion with the antimicrobial coating positioned on the ribbed portion and wherein the ribbed portion is configured to maintain the body part within the cavity, and a cannula, wherein one or more of the plurality of inner surfaces and one or more of the plurality of outer surfaces of the port site and one or more of the plurality of inner surfaces and one or more of the plurality of outer surfaces of the subcutaneous part includes the antimicrobial coating positioned on the one or more of the plurality of inner surfaces of the port site on the one or more of the plurality of outer surfaces of the port site, on the one or more of the plurality of inner surfaces of the subcutaneous part, and on the one or more of the plurality of outer surfaces of the subcutaneous part, and
- the inserter device comprising:
- an outer part comprising one or more locking elements including a first locking element and one or more release elements including a first release element;
- a housing;
- and
- a functional part accommodated in the housing;
- wherein the housing comprises a sidewall with an inner surface forming a cavity, the housing extending from a first end to a second end along a first axis and comprising one or more housing guide members including a first housing guide member for engagement with one or more guide members of the functional part, and where the housing is at least partly covered by the outer part;
- wherein the functional part comprises:
- a first part with a first body extending from a first end to a second end along the first axis, the first part comprising one or more first locking members;
- a second part releasably connected to the first part and comprising a second body extending from a first end to a second end along the first axis, the second part comprising a second guide member and one or more second locking members;
- an insertion needle attached to the second part;
- an insertion spring adapted for moving the first part from a first position to a second position in an insertion direction along the first axis in relation to the housing;
- and
- a retraction spring adapted for moving the second part from the second position to a third position in an extraction direction along the first axis in relation to the housing;
- wherein the first housing guide member and the second guide member are configured for rotating the second part about the first axis when the first part is moved from the first position to the second position, whereby the second part is moved from a locked position to an unlocked position relative to the first part, and
- wherein the inserter system includes a shelf state before activation of the inserter system wherein the body part is not located in the cavity of the port site, and an inserted position where the cannula is inserted into a patient's skin in which the body part is located in the cavity of the port site and the body part is configured to secure the subcutaneous part to the port site.
