Abstract:
Treatment apparatus, system and method are disclosed for treating a biological fluid, such as blood or blood components. The treatment may include but isnot limited to inactivation of pathogens in red cell concentrate. The system may include a disposable fluid circuit assembly and a reusable controller that controls flow through the fluid circuit for reconstituting, if necessary, a treating agent, combining the treating agent with a biological fluid and mixing the agent and biological fluid. An optional quenching agent may also be used.
Abstract:
Systems and methods for manually process blood and blood components in sterile, closed environments, which further condition the blood components for subsequent pathogen inactivation processes. The systems and methods mate the manual collection of random donor platelet units with the creation of larger therapeutic doses of platelets targeted to undergo pathogen inactivation prior to long term storage and/or transfusion.
Abstract:
The present system and method in one embodiment limit a maximum instantaneous peritoneal volume to a comfortable level, while allowing the dialysis machine to advance to fill a prescribed volume whenever the drain ends after a minimum drain percentage has been attained. If a low drain condition occurs, the nominal fill volume is lowered and a therapy cycle is added, so that a prescribed total amount of fresh therapy fluid is used during therapy, maximizing therapeutic benefit. An allowable residual volume at the end of an incomplete drain is increased, thereby lowering the probability of a subsequent low drain condition.
Abstract:
A dialysis system (10a to 10d, 110a, 110b) includes: a portable device (30a to 30c, 90) configured to be carried by a patient (12) and to read a marking (18) displayed on a dialysis fluid container (16), the device (30a to 30c, 90) obtaining data concerning at least one of a dialysis fluid type and a dialysis fluid volume from the marking (18); the device (30a to 30c, 90) further configured to transfer the data to a computer (52, 120); and wherein the computer (52, 120) is configured to use the data to track therapy progress of the patient (12).
Abstract:
Dialysis is enhanced by using nanoclay sorbents to better absorb body wastes in a flow-through system. Nanoclay sorbents, using montmorillonite, bentonite, and other clays, absorb significantly more ammonium, phosphate, and creatinine, and the like, than conventional sorbents. The clays may be used in wearable systems, such as a wearable peritoneal dialysis system, in which the dialysis fluid is circulated through a filter with nanoclay sorbents. Waste products are absorbed by the nanoclays and the dialysis fluid is recycled to the patient's peritoneum. Using the ion-exchange capability of the nanoclays, waste ions in the dialysis fluid are replaced with desirable ions, such as calcium, magnesium, and bicarbonate. The nanoclay sorbents are also useful for refreshing dialysis fluid used in hemodialysis and thus reducing the quantity of dialysis fluid needed for hemodialysis.
Abstract:
A fluid processing assembly (14) can be easily inserted into and removed from a rotatable centrifuge channel (42). The processing assembly (14) comprises a processing container (64) and a carrier (32). The processing container (64) has flexibility and, in use, occupies the channel (42) to receive fluids for separation in the centrifugal field. The carrier (32) retains the processing container (64) outside the channel (42) in a flexed condition conforming to the channel (42). The carrier (32) resists deformation of the processing container (64) during its insertion into or removal from the channel (42).
Abstract:
Systems and methods for hemodialysis or peritoneal dialysis having integrated electrodeionization capabilities are provided. In an embodiment, the dialysis system (10) includes a carbon source (40), a urease source (50) and an electrodeionization unit (30). The carbon source (40) and urease source (50) can be in the form of removable cartridges.
Abstract:
A medical fluid or dialysis system includes an auto-connection mechanism that connects connectors from the supply bags to dialysis cassette ports or cassette supply lines. The system provides for multiple, e.g., four, supply bags, which can be connected to a manifold of the auto-connection mechanism. Tip protecting caps that protect the supply line ends and cassette ports or cassette supply line ends are made to be compatible with the auto-connection mechanism. The auto-connection mechanism removes all the caps and connects the supply lines to the cassette. At least one roller occluder is provided that occludes the supply tubing prior to the tip protecting caps being removed. The roller occludes prevent medical dialysis fluid from spilling out of the supply lines between the time that the caps are removed and connection to the cassette is made.
Abstract:
A peritoneal dialysis system includes: a dialysis fluid container associated with an identifier (118); a reader for reading the identifier (147); a signal transmitter (41) for communicating data based on the identifier; and a patient transfer (150) set for semi-permanent connection to a patient, the patient transfer set including: (i) a signal receiver (141) for receiving the data sent by the signal transmitter, (ii) an output device (146) for communicating with the patient, and (iii) electronics configured to received the data and command the output device to communicate with the patient accordingly.
