Personally portable vacuum desiccator
First Claim
1. A personally portable vacuum desiccator comprising:
- a moisture trap, the trap further comprising a desiccator cartridge having an interior chamber containing a trapping agent and a gas flow channel having a plurality of perforations along the gas flow channel, and the desiccator cartridge further including an inlet port and an outlet port in gas/liquid communication with the interior chamber, the outlet port being connected to the gas flow channel;
a vacuum pump member having a low pressure port and an exhaust port, the low pressure port in gas/liquid flow communication with the outlet port of the desiccator cartridge and with the exhaust port vented to atmosphere, and the vacuum pump member being operable to provide a low vacuum pressure to the interior chamber;
an electric motive means in communication with the vacuum pump member and operative to drive the vacuum pump member; and
an electrical control circuit, including an electrical power source, the control circuit in electrical communication with and operative to control operation of the electric motive means;
wherein said personally portable vacuum desiccator is generally flat and may be worn unobtrusively by a user and is adaptable for collecting and trapping liquid from a wound or incision on the user in said moisture trap.

Abstract
The vacuum desiccator low pressure vacuum pump and trap and is transportable upon a user'"'"'s person. The device is especially useful to remove excess fluids from wounds and incisions as they heal. The device includes a desiccator cartridge containing a fluid trapping agent. The desiccator cartridge is connected to a vacuum pump member providing a low vacuum pressure to the interior chamber of the desiccator cartridge. A small battery powered, electric motor drives the pump member. An electrical control circuit, including the battery power source, controls the operation of the electric motor. A single passage, one-way, gas/liquid flow pathway connects the inlet port of the desiccator cartridge to an occlusive dressing covering the wound to be drained. The control circuit includes one or more ancillary circuits for controlling operation of the device, such as: a power circuit, a moisture sensor, a timer circuit, a vacuum pressure sensor, and a pressure differential sensor.
