An apparatus (1) for cleansing wounds (5) in which irrigant fluid from a reservoir connected to a conformable wound dressing (2) and wound exudate from the dressing are moved by a device (18) (which may be a single pump or two pumps) for moving fluid through a flow path (6, 7, 9, 10) which passes through the dressing with a means for providing simultaneous aspiration and irrigation of the wound, and means for supplying thermal energy to the fluid in the wound. The former provides a desired balance of fluid at a controlled nominal flow rate that removes materials deleterious to wound healing, while distributing materials that are beneficial in promoting wound healing over the wound bed. The latter maintains a temperature at the wound bed under the wound dressing at a level that promotes wound healing.

The invention relates to a drum type washing machine. The invention provides a drum type washing machine with vibration reduced during resonance in the dehydration starting. The drum type washing machine (A) comprises a water tank (3) which supported by a spring (16) and an absorber (7) inside the frame (1), a washing tank (4) rotatably disposed in the water tank (3) for receiving clothes (W), anda motor (5) for driving the washing tank (4) to rotate. A fluid balancer (10) is loaded on the washing tank (4). When the rotation speed is lower than the resonance rotation speed, position of the fluid balancer on the side of the fluid is detected, timing is estimated and the speed is brought up so that the fluid balancer passes through the resonance. When passing through the resonance, positionof the fluid balancer on the side of fluid is on the opposite side of the unbalanced position of the clothes (W), therefore the unbalance of the entire rotation body can be reduced, and vibration canbe reduced.

A fluid replacement device and method. A console includes a weighing subsystem responsive to a first fluid source and a urine collection chamber. A pump is configured to infuse fluid from the first fluid source into a patient. A processing subsystem in the console is responsive to the weighing subsystem. Based on the weight of the first fluid source and the weight of the urine collection chamber, the patient's urine output and the amount of fluid infused into the patient from the first fluid source are determined. A user interface in the console allows the user to set a desired fluid balance for the patient and the amount of at least one additional fluid delivered to the patient. An actual fluid balance is calculated based on the determined urine output, the determined amount of fluid infused into the patient from the first fluid source, and the set amount of the at least one additional fluid delivered to the patient. The pump is controlled based on the actual fluid balance and the set desired fluid balance so the actual fluid balance becomes the same as or approximately the same as the desired fluid balance.
