Inserter for Transcutaneous Sensor
First Claim
1. An inserter for a transcutaneous sensor comprising:
- a housing, the housing comprising housing guiding members on an internal surface of the housing;
a carrier body, the carrier body comprising carrier body guiding members on an external surface of the carrier body, the carrier body guiding members and the housing guiding members guide movement of the carrier body relative to the housing between a retracted and an advanced position;
a needle hub comprising an insertion needle for piercing of the skin and an unreleasable locking member for interacting with a corresponding locking member on the carrier body;
a sensor housing comprising a sensor part configured for subcutaneous placement, the sensor housing and the needle hub releasably connected to each other, the insertion needle is adjoined to the sensor part when the sensor housing and the needle hub are connected, the insertion needle at least partly surrounding the part of the sensor part which is placed subcutaneously; and
a spring unit connected to a release member, the release member being ativatable so that the spring unit moves the sensor housing, the needle hub and the carrier body to an advanced position for subcutaneous placement of the needle and sensor part.

Abstract
The invention relates to an inserter for a transcutaneous sensor comprising a sensor part e.g. for registration of the bloods content of glucose. The inserter comprises a needle unit comprising a needle hub and a carrier body, and a sensor housing. The sensor housing and the needle hub are releasably connected and when they are connected, the insertion needle is placed along the sensor e.g. surrounding the sensor wholly or partly. The carrier body guides the movement relative to the housing between a retracted and an advanced position. When released the needle unit and the sensor housing are forced by a spring unit to an advanced position where the needle and sensor are placed subcutaneously. The object of the invention is to provide a disposable inserter for a transcutaneous sensor which inserter is easy and safe for the user to handle during use and to dispose of after use.
