Abstract
An example urine suction device suitable for extracting urine from a urine collection device is disclosed. The suction device can include a motor, a pump driven by the motor, a conduit, and an acoustic silencer. The pump can extract urine from a urine collection device. The acoustic silencer can be in fluid communication with the pump and conduit. The acoustic silencer can attenuate or reduce one or more acoustic waves generated by the pump and/or the motor. One or more components or structures within the acoustic silencer can at least partially attenuate the acoustic waves as they propagate along a non-linear airflow path defined by the acoustic silencer.
Claims25
A urine suction device, comprising:
- a housing defining an interior volume, the housing defining a recess configured to receive a container, the housing not configured to cover a top of the container, the recess distinct and at least partially spaced from the interior volume;
- a motor disposed in the interior volume;
- a pump disposed in the interior volume, the pump configured to be driven by the motor, the pump being configured to extract urine from a urine collection device;
- one or more conduits disposed in the interior volume, the one or more conduits coupled to the pump and configured to exhaust a fluid from the pump;
- and
- an acoustic silencer disposed in the interior volume, the acoustic silencer in fluid communication with the one or more conduits and the pump, the acoustic silencer defining a non-linear airflow path between an inlet and an outlet of the acoustic silencer, the acoustic silencer including:
- an enclosure defining the inlet and the outlet, the one or more conduits extending through the inlet;
- one or more dividers separating the enclosure into two or more chambers, the one or more dividers defining at least one aperture providing fluid communication between the two or more chambers;
- and
- at least one branched internal conduit distinct and separate from the one or more conduits, the at least one branched internal conduit in fluid communication with a plurality of the two or more chambers of the enclosure, the at least one branched internal conduit is branched downstream of an inlet of the at least one branched internal conduit to form multiple paths through the at least one branched internal conduit;
- and
- wherein the one or more conduits include s a portion extending through the inlet, into the enclosure, and into a plurality of the two or more chambers, the portion of the one or more conduits defines one or more perforations in a side wall thereof, the one or more perforations in fluid communication with the plurality of the two or more chambers.
A system for transporting urine away from a user, the system comprising:
- a urine collection device;
- a container;
- and
- a urine suction device coupled to the urine collection device and configured to draw urine from the urine collection device into the container, the urine suction device comprising:
- a housing defining an interior volume, the housing defining a recess configured to receive the container, the housing not configured to cover a top of the container, the recess distinct and at least partially spaced from the interior volume;
- a motor disposed in the interior volume;
- a pump disposed in the interior volume, the pump configured to be driven by the motor, the pump being configured to extract urine from the urine collection device;
- one or more conduits disposed in the interior volume, the one or more conduits coupled to the pump and configured to exhaust a fluid from the pump;
- and
- an acoustic silencer disposed in the interior volume, the acoustic silencer in fluid communication with the one or more conduits and pump, the acoustic silencer defining a non-linear airflow path between an inlet and an outlet of the acoustic silencer, the acoustic silencer including:
- an enclosure defining the inlet and the outlet, the one or more conduits extending through the inlet;
- one or more dividers separating the enclosure into two or more chambers, the one or more dividers defining at least one aperture providing fluid communication between the two or more chambers;
- and
- at least one branched internal conduit distinct and separate from the one or more conduits, the at least one branched internal conduit in fluid communication with a plurality of the two or more chambers of the enclosure, the at least one branched internal conduit is branched downstream of an inlet of the at least one branched internal conduit to form multiple paths through the at least one branched internal conduit;
- and
- wherein the one or more conduits includes a portion extending through the inlet, into the enclosure, and into a plurality of the two or more chambers, the portion of the one or more conduits defines one or more perforations in a side wall thereof, the one or more perforations in fluid communication with the plurality of the two or more chambers.
A method for reducing noise pollution of a urine suction device with an acoustic silencer, the method comprising:
- supplying power to a motor of the urine suction device, the motor actuating a pump of the urine suction device to transport urine away from a user;
- routing one or more acoustic waves generated by the pump to the acoustic silencer through one or more conduits, the acoustic silencer including:
- an enclosure defining the inlet and the outlet, the one or more conduits extending through the inlet;
- one or more dividers separating the enclosure into two or more chambers, the one or more dividers defining at least one aperture providing fluid communication between the two or more chambers;
- and
- at least one branched internal conduit distinct and separate from the one or more conduits, the at least one branched internal conduit in fluid communication with a plurality of the two or more chambers of the enclosure, the at least one branched internal conduit is branched downstream of an inlet of the at least one branched internal conduit to form multiple paths through the at least one branched internal conduit;
- wherein the one or more conduits includes a portion extending through the inlet, into the enclosure, and into a plurality of the two or more chambers, the portion of the one or more conduits defines one or more perforations in a side wall thereof, the one or more perforations in fluid communication with the plurality of the two or more chambers;
- and
- providing the one or more acoustic waves at an inlet of the acoustic silencer;
- attenuating at least a portion of the one or more acoustic waves along an airflow path formed within the acoustic silencer;
- and
- releasing the one or more acoustic waves from an outlet of the acoustic silencer;
- and
- wherein the urine suction device includes a housing defining an interior volume, the motor, the pump, and one or more conduits, and the acoustic silencer disposed in the interior volume, the housing further defines a recess configured to receive a container, the housing not configured to cover a top of the container, the recess distinct and at least partially separate from the interior volume.
