TRAINER USED TO ACQUIRE HABITS IN CONDUCTING OF VETERINARY MEASURES Russian patent published in 1997 - IPC

FIELD: pedagogics in system of training to acquire sturdy sensomotor habits in taking of blood sampling and injection of drugs both into the vascular system and muscular tissue of animals. SUBSTANCE: the trainer has moulage 1 of the animal head and neck, in which the blood circulation and respiration modelling nodes are installed, the first of which comprises operating condition setting unit 10 and successively connected vessel for liquid, pump 4, jugular vein simulator 2 and throttle 6. The respiratory system modelling node comprises membrane pneumatic actuator 14, vacuum transducer 12 and rhythm setting unit 11. Injector 21 is used as the mechanism of external influence on the animal. The trainer measuring complex has estimation and monitoring unit 20, whose inputs are connected to the outputs of units 10,11 and all modulating transducers such as air pressure transducer 5 at the output of vacuum transducer 12 and liquid pressure transducer 13 at the output of jugular vein simulator 2, and liquid physical properties transducer 7 at the output of the blood circulation system modelling node. The power supply inputs of all units and transducers of the trainer are connected to the respective outputs of power unit 9. EFFECT: enhanced functional and didactic capabilities of the known biotechnical trainers due to perfection of design and technological parameters. 4 cl, 1 dwg
