Negative pressure wound therapy devices

A negative pressure wound therapy system comprising:

• a pump device comprising a source of negative pressure configured to be fluidically connected to a wound covered by a wound dressing;
• a canister coupleable with the pump device and configured to collect fluid aspirated from a wound as a result of negative pressure being provided to the wound by the source of negative pressure;
• and
• a canister release mechanism coupled with the pump device and comprising an actuator coupled with one or more movable latches, the canister release mechanism being configured to cause the pump device to disengage the canister from the pump device when the actuator is depressed;
• wherein:
• the one or more latches are configured to move between a first position in which the one or more latches secure the canister to the pump device and a second position in which the one or more latches release the canister from the pump device when the actuator is depressed.

A negative pressure wound therapy system comprising:

• a device comprising a negative pressure pump actuated by a pump motor, a battery, a display, a lower core assembly, and an upper support within a housing;
• a canister coupleable with the device and configured to collect fluid aspirated from a wound as a result negative pressure being provided by the negative pressure pump to a wound covered by a wound dressing;
• and
• a cap coupled with an opening on the canister;
• wherein:
• the lower core assembly is configured to receive and support at least the pump motor and the battery;
• the upper support is coupled with the lower core assembly, the upper support extending above the lower core assembly;
• the upper support is configured to receive and support at least the display of the pump assembly;
• and
• the display can be removed from the pump assembly by removing the housing and by removing the upper support from the pump assembly.
