Linear, low noise inflation system for blood pressure monitor |
摘要 |
A compact, low noise inflation system for pressurizing occlusion cuffs used in conjunction with automatic blood pressure monitoring equipment. In the preferred embodiment, an electric pump is controlled by a closed-loop, pressure feedback control circuit which compares the cuff pressure with a desired pressurization profile set by the user or stored in a memory device. Acoustic filters are connected to the intake and exhaust ports of the pump to attenuate the intensity of acoustic noise and pressure waves to allow accurate detection of oscillometric pulse data by the blood pressure monitoring system.
