The invention relates to a valve for controlling a flow of a fluid through a fluid channel, comprising a tube of flexible material in which a section of a fluid channel is formed, a valve component assigned to the tube, a squeeze element, which is formed and configured on the valve component by pressing against an outside surface of the tube to control a flow of a fluid through the fluid channel, optionally up to the closing of the fluid channel, a guide section, which is formed on the valve component, and a guide assigned to the valve component, which cooperates with the guide section in a relative movement of the guide and valve components relative to one another in the longitudinal direction of the tube, such that the squeeze element is displaced in the relative movement, changing the pressure on the outside surface of the tube and thus changing the flow through the fluid channel.

The invention relates to a device for the repeated piercing of a skin, with a hand-held device (), which has a drive module () with a drive unit () that is configured for the purpose of producing a driving force, and a needle module () in which a piercing apparatus () is moveably located in the longitudinal direction of the needle module () and which is detachably coupled to the drive module () in such a way that the driving force is conducted into the piercing apparatus (), wherein the needle module () has identification means () which can be evaluated with an evaluation apparatus () allocated to the identification means () and enclosed by the drive module (). Furthermore, the invention relates to a needle module as well as a method for assembling the hand-held device.

Device for the repeated piercing of a skin with a hand-held device, a needle module and a method for assembling the hand-held device

The invention relates to 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, with: a piercing device formed in a needle module with repetitive movement forwards and backwards, which piercing device is driven with the help of a drive unit formed in a drive module, a reservoir for the liquid active substance, a pump system coupled to the reservoir where the said pump system is configured in order to discharge the liquid active substance held in a cavity of the reservoir by means of pressure application, and a fluid connection running at least partially in a needle module casing where said fluid connection is configured in order to supply the liquid active substance from the reservoir to the piercing device.
