Abstract
A medical training model includes a base frame, a fluid system arranged on the frame and configured to simulate a blood circulation replacement system, and at least one additively manufactured individualized vessel model with a patient-specific replicated lumen. The vessel model may be interchangeably connectable to the fluid system by at least one hydraulic quick coupling having coupling pieces such as a plug and a sleeve or bushing. Each coupling piece may contain an inner flow channel, and at least one coupling piece is designed as an adapter with a diameter-changing flow channel course that transitions from the patient-specific lumen to a standardized coupling connection opening. The flow channel course may include a conical region providing a smooth, edgeless transition between differing diameters, with the conical region formed as a hollow shaft truncated cone for flat bearing and sealing when the coupling pieces are locked together.
