Communication systems and methods for negative pressure wound therapy devices

A negative pressure wound therapy device comprising:

• a housing;
• a negative pressure source supported by the housing, the negative pressure source configured to provide negative pressure to a wound covered by a wound dressing;
• an electronic control circuitry supported by the housing, the electronic control circuitry configured to operate the negative pressure source to provide negative pressure in accordance with a set of negative pressure wound therapy parameters;
• a first antenna positioned in first portion of the housing that comprises a top portion of the housing or a side portion of the housing, the first antenna configured to facilitate wireless communications with a remote computing device, and the electronic control circuitry configured to utilize the first antenna to exchange pairing data with the remote computing device using a first communication protocol to allow exchange of data between the remote computing device and the negative pressure wound therapy device;
• a second antenna positioned in a second portion of the housing configured to support a canister that is configured to store exudate aspirated from the wound as a result of provision of negative pressure to the wound, the second portion of the housing different from the first portion of the housing, the second antenna configured to facilitate wireless communications with the canister when the canister is removably attached to the second portion of the housing, the electronic control circuitry configured to utilize the second antenna to receive, from the canister, canister data comprising one or more of a fill status of the canister, an indication that the canister is full, identification data, configuration data, date of manufacture of the canister, or date of first use of the canister, and the electronic control circuitry further configured to use the canister data to control provision of negative pressure to the wound;
• and
• a third antenna configured to facilitate wireless communications with the remote computing device using a second communication protocol that is different from the first communication protocol, the electronic control circuitry configured to utilize the third antenna to transmit data comprising at least one of a location of the housing, logs corresponding to provision of negative pressure, or alarms caused by provision of negative pressure.
