Vacuum regulator with two gauges

A vacuum regulator comprising:

• an electronic gauge and a mechanical gauge, each adapted to take a measurement associated with a vacuum, the electronic gauge having an electronic circuit for processing signals associated with the vacuum, the mechanical gauge having a pneumatic circuit responsive to the vacuum;
• a digital display associated with the electronic gauge, the digital display having a set of digits on an outer surface thereof;
• and
• an analog display associated with the mechanical gauge, the analog display including a gauge face with a vacuum scale and an indicator, the scale and the indicator being movable relative to each other;
• wherein the outer surface of the digital display and the gauge face are secured relative to each other to enable a user of the regulator to obtain a reading corresponding to the vacuum from either the set of digits or the indicator.

A vacuum regulator comprising:

• a vacuum controller in pneumatic communication with a vacuum and adapted to provide a vacuum for medical uses;
• an electronic gauge and a mechanical gauge, each adapted to take a measurement of the vacuum, the electronic gauge including an electronic circuit for processing signals associated with the vacuum, the mechanical gauge including a pneumatic circuit responsive to the vacuum;
• a digital display associated with the electronic gauge, the digital display having a set of digits on an outer surface thereof;
• an analog display associated with the mechanical gauge, the analog display including an indicator and a vacuum scale, the scale and the indicator being movable relative to each other;
• wherein the digital display and the indicator are secured relative to each other to enable a user of the regulator to obtain a reading corresponding to the vacuum from either the set of digits or the position of the indicator relative to the scale;
• wherein the analog display includes a gauge face, the indicator located to physically move relative to the gauge face, the set of digits and the gauge face having respective outer surfaces secured relative to each other to have substantially the same orientation;
• wherein the gauge face has portions defining a window therein, the set of digits located so as to be visible through the window;
• wherein the pneumatic circuit includes a movable element in pneumatic communication with the vacuum, the movable element enclosed in a movable element housing behind the gauge face;
• wherein the electronic gauge includes a circuit board to which the digital display is electrically connected, the circuit board extending behind and secured relative to the gauge face;
• wherein the circuit board is secured so as to be located between the movable element housing and the gauge face.

A vacuum regulator, comprising:

• a housing adapted to be mounted to a wall, the housing having an inlet adapted to connect to a vacuum system;
• the housing having portions defining at least one window therein;
• a vacuum controller operatively connected to the inlet and having a control knob associated therewith;
• and
• a gauge module located within the housing and in pneumatic communication with the inlet;
• wherein the gauge module includes two gauges, and two corresponding displays, each display adapted to display a measurement associated with a vacuum;
• wherein the gauge module is secured relative to the housing so that the displays are visible through the at least one window.
