SUBCUTANEOUS NEEDLE INSERTION MECHANISM

摘要

A subcutaneous access device has a skin attachment plate coated with an adhesive layer. The skin attachment plate is moveably linked by a retraction mechanism to a needle support with fixedly positioned needles. In the ready-to-use position the skin attachment plate is spaced away from the needle support and covers the fixedly positioned needles. Subcutaneous insertion of the needles is effected by attachment of the skin attachment plate with the adhesive layer to the skin and releasing the retraction mechanism, thus triggering the pulling of the attached skin with high velocity against the tip of the needles.

主权项

1. A device for subcutaneous access having means for inserting a needle into an individual's skin by effecting a relative movement between the skin surface and the needle, the device comprising:
a device body in which the needle is held fixedly by a needle support; a skin attachment plate, placed between the device body and the skin and preventing the device body from contacting the skin, having an adhesive surface for attachment to the skin; and a retraction mechanism movably connecting the skin attachment plate with the device body, allowing to keep the skin attachment plate spaced from the device body, and retracting the attachment plate together with the skin towards the needle support.
