Digital pressure gauge

摘要

A vacuum pressure regulator system for use in association with a vacuum system in which a vacuum is employed for healthcare purposes, for assisting in monitoring and regulating the vacuum pressure, and having a manual pressure control valve to adjust the treatment vacuum pressure supplied to the patient, a vacuum pressure sensor to sense the treatment vacuum pressure for the patient in the system, and producing a treatment vacuum pressure signal, a sampling circuit which intermittently samples the pressure signal generated by the pressure sensor and generate sampling signals, an electrically powered pressure display circuit, and digital pressure display, for receiving the sampling signals and providing a visible display, and, a non-mains power supply.

主权项

1. A vacuum pressure regulator comprising:
(a) a digital vacuum pressure display; (b) sensor means for intermittently sensing said vacuum pressure; (c) microprocessor means to intermittently enable the operation of said sensor means to sense said vacuum pressure at predetermined sampling intervals and generate a signal; and (d) power means to power said sensor means and said microprocessor means for generating a digital vacuum pressure reading on said digital vacuum pressure display corresponding to said signal; wherein a sampling rate of the digital vacuum pressure reading of said sampling interval is temporarily increased during adjustment of the vacuum regulator to provide a new digital vacuum pressure reading.
