Electromechanical pricking aid for taking liquid samples
First Claim
1. A portable lancing aid for collecting liquid samples, comprising:
- a lancet system having a spring system and a lancet wherein the spring system drives the lancet in a puncturing movement;
an actuator that tensions the spring system of the lancet system;
a sensor that detects a tension status of the spring system, wherein the actuator is operable to tension the spring system as a function of the detected tension status;
an energy source connected to the actuator; and
an electronic element wherein the sensor transfers the detected tension status to the electronic element, the electronic element triggering the actuator to tension the spring system when the spring system is detected to be in an untensioned state.

Abstract
A portable lancing aid for providing liquid samples comprises a lancet system having at least one lancet, a tensioning device, and an electromechanical actuator. The tensioning device can be tensioned by the electromechanical actuator. The portable lancing aid may further include an energy source for storing electrical energy that is connected to the electromechanical actuator. Additionally, the portable lancing aid may include an interface for charging the energy source where the interface is externally accessible from the lancet system. The invention is ergonomical and easy to handle for children and patients with physical limitations. Furthermore, a lancing system for collecting liquid samples is provided with a portable lancing aid that is detachably mountable to a charging station for charging the portable lancing aid.
