Alcance y aplicabilidad

This standard applies to cardiopulmonary bypass systems specifically utilizing roller blood pumps. It is designed for medical facilities performing surgeries or emergency rescues where the pump temporarily replaces heart function for extracorporeal circulation or local perfusion. Compliance with this standard is mandatory for all manufacturers of these specific medical devices. It does not apply to other types of blood pumps or cardiopulmonary bypass equipment outside the roller pump category.

Requisitos técnicos

The standard outlines comprehensive performance and safety parameters for roller blood pumps. It specifies requirements for both constant flow and pulsatile flow operations, including flow rate tolerances, maximum flow capacities, and rotational speed accuracy. Manufacturers must ensure that their pumps meet the strict performance metrics for both operational modes. Mechanical integrity is heavily emphasized, with specific requirements for roller radial runout, synchronization errors between rollers, and coaxiality between the central axis and the pump body. The standard also mandates specific safety monitoring functions, including pressure, temperature, and time monitoring, as well as critical bubble detection and blood level detection capabilities to automatically halt operation during adverse events. Environmental adaptability and electrical safety are also covered. The equipment must withstand specific climate and mechanical environmental tests as referenced in GB/T 14710-2009, and must comply with the general safety requirements for medical electrical equipment outlined in GB 9706.1 and GB 9706.15. Proper noise level limitations and structural integrity under normal working conditions are also strictly enforced.

Métodos de ensayo

Testing procedures involve visual inspections for structural integrity and utilizing precision instruments like dial indicators to measure mechanical tolerances such as roller runout and synchronization errors. Flow and speed accuracy are tested using water as a blood substitute under specific pressure conditions. Safety features are evaluated by simulating critical conditions, such as injecting specific volumes of air for bubble detection or manipulating blood levels for automatic pump halt testing. Noise levels are measured using an A-weighted sound level meter at a specified distance from the pump head.
