Abstract
Systems, devices, and methods for treating a tissue site on a patient with reduced pressure are presented. In one instance, a reduced-pressure treatment device to treat a tissue site with reduced pressure may include a pump control unit fluidly separate from a collection unit. Pump energy may be provided by the pump control unit to deflect one or more diaphragms within the collection unit to create reduced pressure. Other systems, devices, and methods are presented.
Claims20
A reduced-pressure treatment device for applying a reduced pressure to a tissue site, the reduced-pressure treatment device comprising:
- a pump head comprising a pump chamber, a diaphragm, and a magnetic member associated with the diaphragm;
- and
- a pump control unit magnetically coupled to the pump head and comprising an electromagnet configured to:
- provide an electromagnetic force operable to move the diaphragm to a first position;
- and
- reverse the electromagnetic force to move the diaphragm to a second position.
A pump head for applying a reduced pressure to a tissue site, the pump head comprising:
- a pump chamber;
- a first diaphragm forming at least a portion of the pump chamber, the diaphragm configured to receive a pump energy from a pump control unit and further configured to generate a reduced pressure within the pump chamber in response to the pump energy;
- and
- a second diaphragm fluidly coupled to the pump chamber and configured to measure the reduced pressure.
A pump control unit for applying a reduced pressure to a tissue site, the pump control unit comprising:
- a control device configured to supply a pump energy to at least one linking interface, the linking interface configured to supply the pump energy to a pump head to generate reduced pressure in the pump head;
- a user interface device coupled to the control device and configured to communicate a command from a user to the control device;
- and
- a power subsystem coupled to the control device and the user interface and configured to power the control device and the user interface device;
- wherein the at least one linking interface comprises an electromagnet associated with the pump control unit and a magnetic member associated with the pump head.
