Abstract
An apparatus includes a pressure housing configured to be coupled to a vacuum source and a diaphragm sealingly coupled to the pressure housing. The diaphragm is configured to move in response to the vacuum source. A magnet is coupled to the diaphragm. A magnetic switch is disposed opposite the magnet and is configured to be actuated by the magnet when the magnet is a predetermined distance from the magnetic switch. The magnetic switch is configured to selectively actuate the vacuum source.
Claims20
A wound therapy system, comprising:
- a power supply;
- a vacuum pump coupled to the power supply, the vacuum pump configured to be coupled to a wound dressing;
- a control element coupled to the vacuum pump;
- a shunt resistor coupled to the control element and configured to provide an indication of a vacuum pump current draw associated with the vacuum pump;
- and
- a processor coupled to the control element.
3 more elements
A wound therapy system, comprising:
- a vacuum pump configured to provide negative pressure to a wound dressing;
- a control element coupled to the vacuum pump, the control element configured to switch the vacuum pump between a first mode and a second mode when a control signal based on a vacuum pump current draw reaches a predetermined voltage, the vacuum pump providing less suction when in the second mode than when in the first mode;
- and
- a shunt resistor coupled to the control element, the shunt resistor configured to provide an indication of a vacuum pump current draw to a processor.
1 more element
A wound therapy system, comprising:
- a vacuum pump configured to provide negative pressure to a wound dressing;
- a control element coupled to the vacuum pump;
- a shunt resistor coupled to the control element and configured to provide an indication of a vacuum pump current draw, the vacuum pump current draw being correlated to a pressure level associated with the vacuum pump.
