Patent ID: 8236021

Claim:
A handheld device for the repetitive local puncturing of a skin for an input of a liquid active substance, particularly a permanent make-up and tattoo handheld device, comprising: a piercing device formed in a needle module with repetitive movement forwards and backwards, in which the piercing device is driven by a drive unit formed in a drive module, a needle shaft coupled between the piercing device and the drive module so as to work as a coupling mechanism; a reservoir for the liquid active substance, a portion of the reservoir being disposed in the needle module, a pump system directly attached to the reservoir where the pump system is configured in order to discharge the liquid active substance held in a cavity of the reservoir by a pressure application, a fluid connection running at least partially in a needle module casing where the fluid connection is configured in order to supply the liquid active substance from the reservoir to the piercing device, wherein, at the reservoir, an at least section-wise displaceable component is formed for the purpose of transmitting the pressure application generated by the pump apparatus to the liquid active substance, and wherein the at least section-wise displaceable component is an elastically deformable component and is executed as an elastic membrane, as desired.
