  • Publication number: 20230277830
    Abstract: A hand-held device for local piercing of skin includes: a housing; a drive unit within the housing adapted to provide a driving force; piercing means within the housing having at least one piercing needle disposed on a needle carrier; and coupling means within the housing and connecting the drive unit to the piercing means such that the driving force is transmissible to the piercing means to repeatedly move the needle carrier with the at least one piercing needle between a forward and a rearward position during operation. A lever mechanism receives a drive stroke provided by the drive device via an input of the lever mechanism on the drive side when the driving force is transmitted, to convert the drive stroke into a working stroke which is different from the drive stroke and to output the working stroke to the piercing device via an output of the lever mechanism.

  • Patent number: 11662749
    Abstract: Metered dispensing of a microfluidic amount of fluid from a reservoir comprises a pressure device which applies a discharge pressure for fluid ejection via a discharge line through a valve arrangement. The valve device has a first valve with a minimum closing time and a second valve with a minimum opening time. A control device provides control signals for operation for metered dispensing of the amount of fluid as follows: a shortened minimum opening time for freeing the discharge line for the fluid flow, which time is shorter than the minimum opening time of the second valve; and a shortened minimum closing time for closing the discharge line for the fluid flow, which time is shorter than the minimum closing time of the first valve. Furthermore, a hand-held device for locally piercing human or animal skin is disclosed.

  • Patent number: 9808286
    Abstract: A device for repeated piercing of an organic tissue and method thereof are disclosed. The device may comprise an arrangement of application tools each of which is connected to an operating mechanism and has a distal tool end which is formed for at least one application tool with a penetration device, whereby by way of the operating mechanism the tools can be displaced relative to each other between an initial position and a penetration position. During the relative movement, the effect direction of an application force provided by at least one application tool is counter to the effect direction of the application force provided by the other application tool. A mechanical actuation device, which is connected to the operating mechanism, is suitable for repeatedly effecting the relative displacement of the at least one application tool between the initial position and the penetration with an operating frequency.
