Abstract

An insertion device including an insertion needle holder and a drive mechanism for linearly moving the insertion needle holder in a puncturing direction. The insertion needle holder also includes at least one actuating element for actuating a drive mechanism. The drive mechanism converts a driving motion of the actuating element, which extends transversely or opposite to the puncturing direction, into a puncturing motion of the insertion needle holder.

First claim

What is claimed is:

1. An insertion device comprising:
an insertion needle holder,
a drive mechanism for linearly moving the insertion needle holder in a puncturing direction, and
at least one actuating element for actuating the drive mechanism, wherein a non-linear motion of the drive mechanism converts a driving motion of the at least one actuating element, which extends transversely or opposite to the puncturing direction, into a linear puncturing motion of the insertion needle holder by transferring a force applied to the at least one actuating element to the insertion needle holder;
wherein the drive mechanism converts a driving motion of the at least one actuating element, which extends transversely to the puncturing direction, into a puncturing motion and, immediately thereafter, into retraction motion of the insertion needle holder without reversing the direction of the driving motion; and
wherein the puncturing motion occurs during the driving motion.

2. The insertion device according to claim 1 , wherein the drive mechanism comprises a connecting rod.

3. The insertion device according to claim 1 , wherein the drive mechanism includes a rotor and a connecting rod coupled to the rotor, which converts rotary motion of the rotor into linear motion of the insertion needle holder.

4. The insertion device according to claim 3 , wherein the drive mechanism converts the driving motion of the actuating element into rotary motion of the rotor.

5. The insertion device according to claim 4 , wherein the drive motion of the at least one actuating element is a swivelling motion.

6. The insertion device according to claim 1 , wherein the at least one actuating element includes a rack.

7. The insertion device according to claim 1 , wherein the drive mechanism is disposed in a housing, out of which the at least one actuating element extends.

8. The insertion device according to claim 1 , further comprising a linear guide for the insertion needle holder.

9. An insertion device comprising:
an insertion needle holder,
a drive mechanism for linearly moving the insertion needle holder in a puncturing direction, and
at least one actuating element for actuating the drive mechanism, wherein a non-linear motion of the drive mechanism converts a driving motion of the at least one actuating element, which extends transversely or opposite to the puncturing direction, into a linear puncturing motion of the insertion needle holder by transferring a force applied to the at least one actuating element to the insertion needle holder:
wherein the drive mechanism converts a driving motion of the at least one actuating element, which extends transversely to the puncturing direction, into a puncturing motion and, immediately thereafter, into retraction motion of the insertion needle holder without reversing the direction of the driving motion; and
wherein the insertion device does not include an energy accumulator which contributes a force to drive the puncturing motion of the insertion needle holder.

10. An insertion device comprising:
an insertion needle holder,
a drive mechanism for linearly moving the insertion needle holder in a puncturing direction, and
at least one actuating element for actuating the drive mechanism, wherein a non-linear motion of the drive mechanism converts a driving motion of the at least one actuating element, which extends transversely or opposite to the puncturing direction, into a linear puncturing motion of the insertion needle holder by transferring a force applied to the at least one actuating element to the insertion needle holder;
wherein the drive mechanism converts a driving motion of the at least one actuating element, which extends transversely to the puncturing direction, into a puncturing motion and, immediately thereafter, into retraction motion of the insertion needle holder without reversing the direction of the driving motion; and
wherein the at least one actuating element comprises two actuating elements which are diametrically opposed.

11. The insertion device according to claim 10 , wherein the two actuating elements move in the opposite direction when a puncturing motion occurs.

12. The insertion device according to claim 10 , wherein the two actuating elements move toward one another when a puncturing motion occurs.

13. An insertion system comprising:
an insertion device including:
an insertion needle holder;
a drive mechanism for linearly moving the insertion needle holder in a puncturing direction;
at least one actuating element for actuating the drive mechanism, wherein a non-linear motion of the drive mechanism converts a driving motion of the at least one actuating element, which extends transversely or opposite to the puncturing direction, into a linear puncturing motion of the insertion needle holder by transferring a force applied to the at least one actuating element to the insertion needle holder;

a sensor holder, wherein the insertion device comprises a coupling mechanism that, for insertion, holds the sensor holder against the insertion device and is actuated by the drive mechanism at the end of an insertion procedure to detach the sensor holder from the insertion device; and
wherein the coupling mechanism includes a lever arm which is engaged with the sensor holder during the linear insertion motion of the insertion needle holder and wherein actuation of the coupling mechanism by the drive mechanism at the end of the insertion procedure disengages the lever arm from the sensor holder to thereby detach the sensor holder from form the insertion device.

14. The insertion system of claim 13 wherein the lever arm of the coupling mechanism has a pivotal connection.
