Abstract

The invention relates to a device for piercing an organic tissue, and more particularly to piercing human or animal skin. The device includes a housing, a piercing unit, which is accommodated in the housing, and an actuator device which is arranged and configured in the housing to generate an actuating force in such a way that an actuator component surrounded by the actuator device and functionally connected to the piercing unit, performs an oscillating actuating movement in the housing which is coupled to the piercing unit. The actuating device is designed with a counter component allocated to the actuating component which at least partially compensates for vibrations caused in the housing by the oscillating actuating movement of the actuating component; the counter component oscillates and is moved contrary to the actuating component. The invention also relates to an actuation module for a device for piercing an organic tissue.

Claims

1. A device for piercing an organic tissue, such as human or animal skin, comprising:

a housing,

a piercing unit, which is accommodated in the housing, and

an actuating device, which is arranged and configured in the housing to produce an actuating force so that an actuating component which is surrounded by the actuating device and functionally coupled to the piercing unit performs an oscillating actuating movement in the housing which is coupled to the piercing unit,

wherein the actuating device is designed with a counter component which is assigned to the actuating component and in the housing at least partially compensates for the vibrations caused by the oscillating actuating movement of the actuating component in that during the oscillating actuating movement of the actuating component the counter component is moved in an oscillating manner in the housing and contrary to the direction of the actuating component.

2. The device according to claim 1, wherein the oscillating actuating movement is an axial actuating movement.

3. The device according to claim 1, wherein the actuating component and the counter component are arranged in a kinematic chain.

4. The device according to claim 1, wherein the mass of the actuating component is essentially equal to the mass of the counter component.

5. The device according to claim 1, wherein a spring element is assigned to the actuating component (12) during the oscillating actuating movement at least in terms of a forward movement or at least in terms of a backwards movement.

6. The device according to claim 1, wherein a spring element is assigned to the counter component during the oscillating actuating movement at least in terms of a forward movement or at least in terms of a backwards movement.

7. The device according to claim 1, wherein the counter component is designed as a passive component, which is passively moved during the oscillating actuating movement of the actuating component.

8. The device according to claim 1, wherein the counter component is designed as an active component which during the oscillating actuating movement of the actuating component is actuated by a component actuating device assigned to the counter component and is thus actively moved.

9. The device according to claim 1, wherein the actuating device is designed with a vibration drive from the following group:

actuator with plunger anchor, actuator with tension anchor, parallel vibration motor, Lorentz force-driven linear actuator with movable coil or movable rotors, torsion vibration actuator, Piezo actuator, ultrasonic actuator and pneumatic vibration actuator.

10. The device according to claim 1, wherein the actuating device is configured to actuate the actuating component and/or the counter component in a mechanically contact-free manner.

11. An actuation module for a device for piercing an organic tissue, such as human or animal skin, comprising:

a module housing and

an actuating device, which is arranged and configured in the module housing to couple to a piercing unit of a needle module and to produce an actuating force so that an actuating component which is surrounded by the actuating device and can be functionally coupled to the piercing unit, performs an oscillating actuating movement in the module housing which can be coupled to the piercing unit,

wherein the actuating device is designed with a counter component which is assigned to the actuating component and in the module housing at least partially compensates for the vibrations caused by the oscillating actuating movement of the actuating component in that during the oscillating actuating movement of the actuating component the counter component is moved in an oscillating manner in the module housing and contrary to the direction of the actuating component.
