Abstract

1. Es handelt sich um ein elektronisch gesteuertes Gerät zur präzisen Konditionierung von Versuchstieren mit Hilfe eines Wechsel- oder Gleichstromimpulses bei kontinuierlicher Überprüfung der resultierenden Stromstärke. Inklusive Regelung der Stromstärke und evtl. Verlängerung des Impulses. 2.1. Derzeit bekannten Vorrichtungen ist gemeinsam, daß eine geringe und nicht einstellbare Spannung eingesetzt wird (max. 230 V), bei evtl. zu hohem elektrischem Widerstand des Tieres. Des weiteren ist bei Bewegungen des Tieres die resultierende Stromstärke und Impulsdauer nicht bekannt. Damit kann keine qualifizierte Aussage über den tatsächlich verabreichten Stromimpuls gemacht werden und somit über die Konditionierung. Aufgabe der Erfindung ist es daher ein in engen Grenzen konditioniertes Tier zu erzeugen. 2.2. Dieses Gerät nutzt für den Stromimpuls eine Hochspannungsquelle (1) von ~1 kV und einer mittels Mikrocontroller (5) gesteuerten Widerstandsschaltvorrichtung (2), die den Strom (typ. 20 uA bis 500 uA) durch das Tier regelt. Die sich ergebende Spannung und Stromstärke wird durch einen AD-Wandler (3) gemessen und bei Bedarf nachgeregelt. Die voreingestellte Impulsdauer wird gemessen (6) und evtl. verlängert. Durch eine vorangehende Widerstandsmessung des Tieres wird die Kontaktqualität zum Versuchsgitter (7) bestimmt. 2.3. Nach der erfolgten Konditionierung des Tiers erhält der Experimentator eine qualifizierte Aussage (4) über den durch das Tier geleiteten Stromimpuls und evtl. aufgetretene Fehler.1. It is an electronically controlled device for precise conditioning of experimental animals using an AC or DC pulse with continuous verification of the resulting current. Including control of the current and possibly extension of the pulse. 2.1. Currently known devices have in common that a low and non-adjustable voltage is used (max 230 V), possibly too high electrical resistance of the animal. Furthermore, in movements of the animal, the resulting current and pulse duration is not known. Thus, no qualified statement can be made about the actually applied current pulse and thus about the conditioning. The object of the invention is therefore to produce an animal conditioned within narrow limits. 2.2. This device uses a ~ 1 kV high voltage source (1) and a microcontroller (5) controlled resistance switching device (2) to control the current pulse (typically 20 uA to 500 uA) through the animal. The resulting voltage and current is measured by an AD converter (3) and readjusted if necessary. The preset pulse duration is measured (6) and possibly extended. By a preceding resistance measurement of the animal, the contact quality to the experimental grid (7) is determined. 2.3. After conditioning the animal, the experimenter receives a qualified statement (4) about the current pulse passed through the animal and any errors that have occurred.

Derzeit bekannten Vorrichtungen ist gemeinsam, daß eine geringe und nicht einstellbare Spannung eingesetzt wird (max. 230 V), bei evtl. zu hohem elektrischem Widerstand des Tieres.
