Internal needle inserter
First Claim
1. A medical device (100, 400) comprising:
- a housing (110, 120) having a mounting surface (121) adapted for application to the skin of a subject, a transcutaneous device with a distal pointed end portion (151, 451, 461) adapted to penetrate the skin of the subject, the transcutaneous device having a first position in which the distal end portion is retracted within the housing, and a second position in which the distal end portion projects relative to the mounting surface, actuatable driving means (137, 454, 464) disposed within the housing and adapted to move the transcutaneous device from the first position to the second position when the driving means is actuated, wherein the driving means is actuatable from a first state through an intermediate state to a second state, whereby actuation of the driving means from the first to the intermediate state causes activation of the driving means, and actuation of the driving means from the intermediate to the second state causes release of the activated driving means thereby moving the transcutaneous device from the first position to the second position.

Abstract
A device comprises a housing having a mounting surface adapted for application to the skin of a subject, a needle with a pointed end portion adapted to penetrate the skin the subject, the needle having a first position in which the distal end portion is retracted within the housing, and a second position in which the distal end portion projects relative to the mounting surface. The device further comprises actuatable driving means actuatable to cause activation as well as release of the driving means, thereby moving the needle from the first position to the second position. By this arrangement the needle device can be supplied to the user in a non-energized state, the energizing taking place when the device is actuated by the user which means that energy will be stored only for a period from a few seconds to a few hours or days.
