| 20090084379 | DRY POWDER INHALER - An dry powder inhaler is disclosed. The dry powder inhaler is designed so that a user's breath vacuums the dry powder from a well within the housing and directs the powder in a direct path to the user. This design prevents impaction and agglomeration of powder within the inhaler. A flow restrictor may be added within the inhaler to increase turbulence and thus increase dispersion of powder within the air inhaled by the user. | 04-02-2009 |
| 20090084718 | DIALYSIS SYSTEMS HAVING AIR TRAPS WITH INTERNAL STRUCTURES TO ENHANCE AIR REMOVAL - A dialysis fluid cassette includes a rigid portion defining first and second valve chambers, the rigid portion further defining an air separation chamber in fluid communication with the first and second valve chambers, the air separation chamber including a baffle and structured such that when the cassette is placed in a dialysis instrument, (i) the baffle extends upwardly from a bottom of the air separation chamber and (ii) first and second openings to the air separation chamber, communicating fluidly and respectively with the first and second valve chambers, are located near the bottom of the air separation chamber, such that the dialysis fluid is forced up one side of the baffle and down the other side of the baffle when flowing through the air separation chamber. | 04-02-2009 |
| 20090084719 | DIALYSIS SYSTEMS HAVING AIR SEPARATION CHAMBERS WITH INTERNAL STRUCTURES TO ENHANCE AIR REMOVAL - A dialysis fluid cassette includes a rigid portion defining at least one valve chamber, the rigid portion further defining an air separation chamber, the air separation chamber when in an operating position including a first sidewall and a second sidewall, a first fluid opening, a second fluid opening, and a separation wall extending from the first sidewall to the second sidewall, the separation wall having a free edge residing within the air separation chamber, the separation wall forcing the dialysis fluid to flow from one of the fluid openings around the free edge of the separation wall to the other of the openings. | 04-02-2009 |
| 20090084721 | DIALYSIS SYSTEMS HAVING AIR SEPARATION CHAMBERS WITH INTERNAL STRUCTURES TO ENHANCE AIR REMOVAL - A dialysis fluid cassette includes a rigid portion defining at least one valve chamber, the rigid portion further defining an air separation chamber, the air separation chamber when in an operating position including an inner surface, a fluid inlet and a fluid outlet and configured to cause a dialysis fluid to spiral around the inner surface toward the fluid outlet, such that air is removed from the dialysis fluid. | 04-02-2009 |
| 20100136679 | Apparatus and Method for Processing Biological Material - The application discloses an apparatus and method for processing biological material, including a suspension of cells. | 06-03-2010 |
| 20110092895 | DIALYSIS SYSTEMS HAVING SPIRALING FLUID AIR SEPARATION CHAMBERS - A dialysis fluid cassette includes a rigid portion defining at least one valve chamber, the rigid portion further defining an air separation chamber, the air separation chamber when in an operating position including an inner surface, a fluid inlet and a fluid outlet and configured to cause a dialysis fluid to spiral around the inner surface toward the fluid outlet, such that air is removed from the dialysis fluid. | 04-21-2011 |
| 20110137236 | FLUID DELIVERY SYSTEMS AND METHODS HAVING FLOATING BAFFLE AIDED AIR REMOVAL - A medical fluid delivery system includes a fluid disposable configured to hold and transport a medical fluid and an air separation chamber in fluid communication with the fluid disposable. The air separation chamber includes at least one fluid baffle floating within the air separation chamber and configured to separate air from medical fluid traveling through the chamber. | 06-09-2011 |
| 20110137237 | DIALYSIS SYSTEMS AND METHODS HAVING VIBRATION-AIDED AIR REMOVAL - A dialysis system includes a dialysis fluid disposable configured to hold and transport a dialysis fluid; an air separation chamber in fluid communication with the dialysis fluid disposable; and a dialysis instrument operable to pump dialysis fluid through the dialysis fluid disposable, the instrument including a vibrator configured to vibrate the air separation chamber to separate air from the dialysis fluid traveling through the chamber. | 06-09-2011 |
| 20110144557 | DIALYSIS SYSTEMS AND METHODS INCLUDING CASSETTE WITH FLUID HEATING AND AIR REMOVAL - A dialysis fluid system includes an instrument including a pump actuator and a fluid heater, and a dialysis fluid cassette. The dialysis fluid cassette includes a rigid portion defining a pumping section for operation with the pump actuator and a heating section for operation with the fluid heater. The heating section includes a dialysis fluid inlet, a dialysis fluid outlet, and a dialysis fluid heating area located between the fluid inlet and the fluid outlet, the heating section further includes an air separation chamber for collecting air separated from the dialysis fluid. | 06-16-2011 |
