Abstract
A reduced-noise pump system for use with a wearable medical device includes a pump housing. The pump system may be used with any number of different wearable medical devices, including wearable negative pressure wound therapy devices. Provided within the pump housing is a pump, a power source and one or more acoustically insulating elements. Examples of acoustically insulating elements that may be provided within the pump housing are an encasement layer, a baffle, and a pump cover. A control unit may be optionally also be provided, with the control unit being configured to under-drive the power source of the pump system in order to reduce the operating noise of the pump.
Claims30
A wearable, self-contained, negative pressure wound therapy device, comprising:
- a dressing module comprising:
- a dressing configured for placement in or over a wound;
- a drape configured for placement over the dressing and for sealing to a patient proximate the wound;
- a dressing interface connector disposed on the drape and having an opening communicating with the dressing;
- a pump module configured to be releasably connected to the dressing module, the pump module comprising:
- a top cover and a bottom cover defining a cavity therebetween;
- a pump interface connector defining a suction passageway therethrough and configured to reasonably engage the dressing interface connector;
- a pump disposed within the cavity and operably coupled to the pump interface connector to draw a suction through the suction passageway;
- a battery disposed within the cavity and coupled to the pump;
- and
- acoustic insulation disposed within the cavity proximate the pump.
A noise-reducing pump housing for a wearable therapy device, the housing comprising:
- a top layer having an upper surface and a lower surface;
- a bottom layer having an upper surface and a lower surface, an outer periphery of the lower surface of the top layer being sealed to an outer periphery of the upper surface of the bottom layer to define a housing interior;
- a pump located within the housing interior;
- and
- a noise reducing element attached to the pump.

A method of replacing a negative pressure wound therapy dressing, comprising:
- disconnecting a pump module from a used dressing module, wherein the used dressing module comprising a dressing, a drape disposed over the dressing, and a dressing interface connector disposed on the drape, and wherein the pump module comprises a top cover and a bottom cover defining a cavity therebetween, a pump interface connector defining a suction passageway therethrough and configured to reasonably engage the dressing interface connector, a pump disposed within the cavity and operably coupled to the pump interface connector to draw a suction through the suction passageway, a battery disposed within the cavity and coupled to the pump, and acoustic insulation disposed within the cavity proximate the pump;
- applying a new dressing module to a wound site;
- and
- connecting the pump module to the new dressing module by engaging the pump interface connector to the dressing interface connector.
