Abstract: The invention relates to a method for purifying at least one reaction product of at least one diisocyanate, comprising at least the following steps: (A) providing a mixture A at least containing the at least one reaction product of the at least one diisocyanate and, if applicable, the at least one diisocyanate, (B) adding, if applicable more of, at lease one diisocyanate to mixture A from step (A) in order to obtain a mixture B, and (C) separating off the at least one diisocyanate from mixture B from step (B) by distillation in order to obtain the purified at least one reaction product of the at least one diisocyanate. Furthermore, the present invention comprises the reaction product of at least one diisocyanate which can be obtained by the method according to the invention and the use thereof for producing polyurethane foams, polyurethane hydrogels, polyurethane elastomers, varnishes and bonding adhesives.

Abstract: An adapter for mechanically/electrically connecting an implantable electrode, via the proximal connector thereof including at least one connecting contact for the electrode, to at least one test terminal contact of a measuring device, includes an electrically insulating adapter housing, a connector receiving element adapted to connector shape, and at least one contact element disposed in the adapter housing establishing contact between the at least one connecting contact of the connector and the at least one test terminal. A receiving tray, having the receiving element for the connector, is mounted on the adapter housing and variable between open and closed contact positions. In the open position, the connector is inserted in the receiving element in a defined position and removed therefrom. In the contact position, the at least one connecting contact of the connector is brought in contact with the contact element in the adapter housing in a defined manner.

Abstract: A pacemaker comprising a battery compartment displaceable between a removal position and an operating position along a first direction of displacement for receiving a replaceable battery having a first and a second battery pole disposed on a battery face. The battery compartment comprises an electrically isolating partial cover, which is disposed on a second side opposite the first side and designed to cover a base of the battery directed toward the second side in the direction of the removal side of the battery compartment.
