    Abstract: A method is provided for detecting filter clogging which are able to keep track of the filter clogging with precision and in detail. At least one pressure selected from the group consisting of a pressure Pa in a blood inflow portion (32a), a pressure Pv in a blood outflow portion (32b), a pressure Pf1 in a filtrate inflow portion (32c), and a pressure Pf2 in a filtrate outflow portion (32d) is measured continuously, then a variation (pressure waveform) of the pressure is analyzed, a clogging of a filter (32) is detected using the analyzed result. Thereby a clogging of a filter is detected early. As a result, it is possible to prevent from developing of the filter clogging by controlling a dosage amount of anti-coagulant properly and changing a flow rate of blood. The variation of the pressure wave may be analyzed by subjecting the variable to Fast Fourier Transform.

    Abstract: The invention features methods and apparatus for the treatment of asthma patients. A controlled supply of breathable air delivered to a patient interface or mask (4) is controlled for patient comfort to maintain a steady pressure level in a range 2 to 4 cm H2O to accommodate patient respiration. The breathable air is cleaned by a high efficiency particulate arresting filter (10) to remove allergens from the air supply. The apparatus may be programmed to automatically detect asthma-related symptoms such as an asthma attack by analyzing the respiratory flow of the patient. In response to the detection of such an attack, the apparatus may provide an audible warning or if configured with a treatment delivery module (14A, 14B), the device may administer a therapeutically effective dose of a drug or substance, for example, a broncho-dilator, to alleviate the patient's breathing difficulty. Preferred mask designs allow for proper CO2 washout to accommodate the low pressures supplied to the mask and prevent asphyxia.

    Abstract: An extracorporeal blood perfusion system (1) includes a disposable assembly (100) and a control unit (10) having a control interface region (50). The interface region includes pump assemblies (31-36) for selective pumping of venous blood, arterial blood, cardioplegia solution, suctioned blood, and blood removed from the left ventricle. Valve assemblies control the flow of fluids through the assembly and to/from the patient and sensors monitor various fluid parameters including temperature and pressure within the various fluid circuits. The user interface (50) is a functional screen interface for effecting the operation of the control unit and valve assemblies. The screen interface may be a touch screen having objects that corresponds to the component interface region. The display (54) may be selectively controlled to provide graphic depictions of disposable assembly components with corresponding narrative instructions.

    Abstract: A device for aerosolizing a liquid includes a chamber (502) having a deformable wall (510) which expands and contracts as fluid is delivered and expelled from a fluid chamber (500). The chamber is partially bounded by a vibrating structure (506) having holes (504) therein for expelling the fluid. In another aspect, the invention provides exemplary aerosolization apparatus (300) and methods for aerosolizing a substance. A liquid is transferred from a first chamber (328) into a second chamber (330) having a substance that is in a dry state to form a solution. The solution is then transferred from the second chamber and onto an atomization member (308). The atomization member is operated to aerosolize the solution.
