Adapter for mechanically and electrically connecting an implantable electrode to at least one test terminal contact

1. An adapter for mechanically and electrically connecting an implantable electrode, by means of a proximal connector thereof comprising at least one connecting contact for an electrode surface of the electrode, to at least one test terminal contact, in the form of an alligator clip, of a measuring device, the adapter comprising:

an adapter housing made of an electrically insulating material;

a receiving element for the proximal connector which is adapted to a shape of the proximal connector;

at least one contact element disposed in the adapter housing for establishing contact between the at least one connecting contact of the proximal connector and the at least one test terminal contact; and

a receiving tray mounted on the adapter housing so as to be variable between an open position and a closed contact position and in which the receiving element for the proximal connector is disposed, wherein:

in the open position, the proximal connector is insertable in the receiving element in a defined position and is removable therefrom; and

by transferring the receiving tray into the contact position, the at least one connecting contact of the proximal connector enables contact with the contact element in the adapter housing in a defined manner,

wherein the receiving tray is a drawer that is displaceable between the open position and the contact position on the adapter housing, and

wherein the displacement direction of the drawer is transversely to a longitudinal direction of the proximal connector.

2. The adapter according to claim 1 , wherein the receiving tray can be fixed in the open position and/or contact position relative to the adapter housing by a latching engagement.

3. The adapter according to claim 2 , wherein the latching engagement can be detached by way of a trigger button.

4. The adapter according to claim 3 , wherein the trigger button is coupled to the adapter housing via a spring tongue.

5. The adapter according to claim 2 , wherein the latching engagement comprises a detent tongue and projection disposed on the receiving tray configured to engage a detent recess disposed on the adapter housing.

6. The adapter according to claim 1 , wherein the at least one connecting contact of the proximal connector is completely covered toward the outside in the contact position of the receiving tray.

7. The adapter according to claim 1 , wherein, in front of the proximal connector positioned in the receiving tray, the receiving tray and the adapter housing are provided at their end faces with an opening to provide unobstructed access to a central electrode lumen guided through the proximal connector, both in the open position and in the contact position.

8. The adapter according to claim 7 , wherein the opening is configured to enable at least one of manipulation and replacement of a mandarin without a change in position of the adaptor and the proximal connector.

9. The adapter according to claim 1 , wherein the at least one contact element in the adapter housing has an outwardly exposed contact surface for the at least one test terminal contact.

10. The adapter according to claim 1 , wherein a guide for the at least one test terminal contact flanks a surface of the at least one test terminal contact.

11. The adapter according to claim 1 , wherein, in an adapter for the proximal connector comprises connectors comprising a plurality of connecting contacts, the receiving tray and the adapter housing are designed for the electrical connection of two or four connecting contacts to two test terminal contacts, in each case via a contact element.

12. The adapter according to claim 11 , wherein a polarity symbol is associated in each case with the contact elements.

13. The adapter according to claim 11 , wherein a polarity symbol is associated in each case with exposed contact surfaces of the contact elements.

14. The adapter according to claim 1 , wherein the adapter housing comprises more than four contact elements for connecting test terminal contacts.

15. The adapter according to claim 1 , wherein the adapter housing comprises eight contact elements for connecting test terminal contacts.

16. The adapter according to claim 1 , further comprising at least one circuit board disposed on the adapter housing, each individual circuit board having two metallic strip contact elements.

17. The adapter according to claim 1 , further comprising at least one ridge-shaped configuration disposed on a face of the adapter housing, wherein the at least one ridge-shaped configuration is configured to prevent alligator clips that have been attached to the adapter from sliding off.
