| 20080203023 | LAST-CHANCE QUALITY CHECK AND/OR AIR/PATHOGEN FILTGER FOR INFUSION SYSTEMS - Blood treatment system and method for high rate hemofiltration ensures against pyrogenic patient reaction by providing various mechanisms for filtering replacement fluid to remove endotoxins and other safety features including detecting incorrect fluid administration. | 08-28-2008 |
| 20080228125 | Methods and Devices for Rendering Different Types of Patient Access Devices Compatible with Different Types of Tubing Sets - In general, this invention relates to methods and devices for introducing and/or draining fluids into and/or from a patient's body. Methods and devices are provided for rendering conventional tubing sets, or fluid flow sets, which are normally coupleable with only specific complementary patient access devices, compatible with other access devices also. In accordance with one aspect of the invention, methods and devices are provided which render conventional extracorporeal tubing sets to be interchangeably connectable with other specific transcutaneous catheters. In yet another aspect of the invention, non-conventional tubing sets and corresponding non-conventional access devices for use in hemodialysis, or hemofiltration, are provided such that specific tubing sets and access devices can be used interchangeably. | 09-18-2008 |
| 20080230450 | Filtration System for Preparation of Fluids for Medical Applications - Systems, methods, and devices for preparation of water for various uses including blood treatment are described. In embodiments, fluid is passed either by pump or passively by gravity feed, through various filtration elements from a fluid source to a treatment fluid container The latter forms a batch that may be used during treatment. Methods and systems for creating multiple-treatment batches are described. Advantages of creating a multitreatment batch include the fact that the burden of treatment preparation can be reduced and the timing of the preparation of the batch can be independent of the treatment time. As described, there are various trade-offs and concerns with this approach which are addressed by the inventive embodiments. | 09-25-2008 |
| 20080306426 | Blood flow control in a blood treatment device - A first flow path is defined within a first panel that forms a part of an extracorporeal fluid circuit. A second flow path is defined within a second panel that also forms a part of the extracorporeal fluid circuit. The first and second panels are oriented in a fluid processing cartridge for mounting as an integrated unit on a fluid processing machine and for removal as an integrated unit from the fluid processing machine. | 12-11-2008 |
| 20090012442 | Registration of fluid circuit components in a blood treatment device - A first flow path is defined within a first panel that forms a part of an extracorporeal fluid circuit. A second flow path is defined within a second panel that also forms a part of the extracorporeal fluid circuit. The first and second panels are oriented in a fluid processing cartridge for mounting as an integrated unit on a fluid processing machine and for removal as an integrated unit from the fluid processing machine. | 01-08-2009 |
| 20090211975 | Batch Filtration System for Preparation of Sterile Fluid for Renal Replacement Therapy - A method and device for blood treatments that use fluids such as dialysate and replacement fluid for renal replacement therapy. In an embodiment, fluid is passed either by pump or passively by gravity feed, through a microporous sterilization filter from a fluid source to a replacement fluid container. The latter forms a batch that may be used during treatment. The advantage of forming the batch before treatment is that the rate of filtering needn't match the rate of consumption during treatment. As a result, the sterilization filter can have a small capacity. In another embodiment, a filter is placed immediately prior to the point at which the sterile fluid is consumed by the treatment process. The latter may be used in combination with the former embodiment as a last-chance guarantee of sterility and/or that the fluid is free of air bubbles. It may also be used as the primary means of sterile-filtration. | 08-27-2009 |
| 20090222671 | SAFETY FEATURES FOR MEDICAL DEVICES REQUIRING ASSISTANCE AND SUPERVISION - An automatic locking system for a medical treatment device helps to ensure that an assistant is present during treatment of a patient. Among the features disclosed biometric authentication to verify that a trained assistant is present, a presence detector to ensure the assistant is continuously present during treatment, and warning and recovery processes that allow intermittent lapses in the continuous presence of the assistant. | 09-03-2009 |
| 20090236027 | Blood Treatment Filter and Method of Manufacturing - A configuration of a blood microtubular filter/dializer used in many kinds of renal replacement therapy systems is disclosed which may allow a straight thin-walled tube to be used for a majority of the structure of the housing and other benefits disclosed. | 09-24-2009 |
| 20100016777 | WASTE BALANCING FOR EXTRACORPOREAL BLOOD TREATMENT SYSTEMS - One or more waste balancing systems may be used in a fluid circulating system for medical use. The fluid circulating system may be part of a blood treatment system for a patient suffering renal failure. A waste balancing system may include a pressure element operable to maintain a constant fluid pressure created by the combined weight of waste removed from a patient and replacement fluid for providing to a patient. Multiple evaluation characteristics or control parameters may be evaluated or controlled for safety and accuracy. At least part of the waste balancing system may be incorporated into a disposable cartridge. | 01-21-2010 |
| 20100228177 | BATCH FILTRATION SYSTEM FOR PREPARATION OF STERILE FLUID FOR RENAL REPLACEMENT THERAPY - A method and device for blood treatments that use fluids such as dialysate and replacement fluid for renal replacement therapy. In an embodiment, fluid is passed either by pump or passively by gravity feed, through a microporous sterilization filter from a fluid source to a replacement fluid container. The latter forms a batch that may be used during treatment. The advantage of forming the batch before treatment is that the rate of filtering needn't match the rate of consumption during treatment. As a result, the sterilization filter can have a small capacity. In another embodiment, a filter is placed immediately prior to the point at which the sterile fluid is consumed by the treatment process. The latter may be used in combination with the former embodiment as a last-chance guarantee of sterility and/or that the fluid is free of air bubbles. It may also be used as the primary means of sterile-filtration. | 09-09-2010 |
| 20100228231 | FLUID LINE CONNECTOR SAFETY DEVICE - The present application describes devices that use various features to prevent the disconnection of connectors used in medical treatments. For example embodiments prevent disconnection of luer connectors that are incompletely mated. | 09-09-2010 |
| 20110106047 | METHODS, DEVICES, AND SYSTEMS FOR PARALLEL CONTROL OF INFUSION DEVICE - A tubing set is disclosed that includes a first line having first and second ends, a bag spike at the first end configured for connection to a source of infusate, and a connector at the second end configured for connection to a blood line. The first line can have a pumping portion for engagement with an infusate pump. The tubing set can also include a second line having first and second ends, the second line first end being attached to the first line between the first line pumping portion and the first line second end and the second line second end being configured for connection to the first line between the first line first end and the first line pumping portion. The tubing set can further include a check valve located in the second line, the check valve having a predetermined cracking pressure of at least 200 mm Hg. The second line second end can be configured for connection to the first line by a dual lumen spike such that when a container is connected to the dual lumen spike, a bypass loop is formed that permits a flow from a second end side of the pumping portion to the first end side of the pumping portion. The first line can include a spike septum at the first end thereof. | 05-05-2011 |
