  • Patent number: 12011532
    Abstract: A negative pressure wound therapy system can include a negative pressure source configured to provide, via a fluid flow path, negative pressure to a wound covered by a wound dressing. The system can include a controller. The controller can be configured to periodically activate the negative pressure source to maintain negative pressure in the fluid flow path between a low negative pressure setpoint and a high negative pressure setpoint. The controller can be configured to determine a change in a volume of the wound based on a difference between a first time and a second time at which the high negative pressure setpoint has been established in the fluid flow path, the second time being subsequent to the first time. The controller can be configured to provide indication of the change in the volume of the wound.

  • Patent number: 11969571
    Abstract: A multi-use disinfecting cap and method for disinfection and protection of a needleless IV injection port. The disinfecting cap has an upper chamber which contains a sterilizing solution and a low chamber which connects to a needleless IV injection port. The fluid can be manipulated to flow between the two chambers. When in use the cap protects and disinfects a needleless IV injection port when exposed prior to injecting medication into the needleless port and continues to disinfect and protect prior for any subsequent exposures. The cap is re-usable and provides a clear indication of the disinfecting solution and a datable top surface. The multi-use disinfecting cap may be removably clipped to the IV tubing and is shaped to prevent accidental rolling away if dropped.

    Abstract: A dialysis machine (e.g., a peritoneal dialysis (PD) machine) can include a pressure sensor mounted at a proximal end of a patient line made of a distensible material that provides PD solution to a patient through a catheter. During treatment, an occlusion can occur at different locations in the patient line and/or the catheter. When an incremental volume of additional solution is provided to the patient line while the occlusion is present, a change in pressure results. The change in pressure depends on dimensions and a distensibility of a non-occluded portion of the patient line. If the change in pressure, the incremental volume, properties related to the distensibility of the patient line, and some of the dimensions of the patient line are known, a location of the occlusion can be inferred. An occlusion type can be inferred based on the inferred location.

  • Patent number: 10874790
    Abstract: The invention relates to systems and methods for making intracycle adjustments to an osmotic agent concentration of peritoneal dialysate inside the peritoneal cavity of a patient. The systems and methods include osmotic agent sources, flow paths, and processors to adjust the osmotic agent concentration of dialysate in the peritoneal cavity of the patient. The method can include infusing peritoneal dialysate containing an osmotic agent into the peritoneal cavity of a patient; monitoring one or more patient parameters; and adjusting the osmotic agent concentration of the peritoneal dialysate in the peritoneal cavity of the patient by infusing a concentrated osmotic agent solution or by infusing sterile fluid into the peritoneal cavity of the patient using an on-line peritoneal dialysis machine. The system can include a peritoneal dialysis cycler.

  • Patent number: 10806843
    Abstract: A method for operating a dialysis machine to conduct a dialysis treatment on a patient (e.g., a peritoneal dialysis machine) may include transferring dialysate from a first bag, and automatically determining the dialysate from the first bag has completely transferred. After determining the dialysate has completely transferred from the first bag, switching from the first bag to a second bag of dialysate. The method may further include transferring dialysate from the second bag in response to the detection of the completed transfer of the first bag, and automatically determining the dialysate from the second bag has completely transferred. The method may further include determining if the respective first or second bag has completely transferred by comparing a dialysate bag volume transferred to the patient to a detected volume of the respective first or second bag. Systems with dialysis machines for performing such a method are disclosed as well.

  • Patent number: 10744253
    Abstract: The invention relates to systems and methods for adjusting one or more dialysis parameters for delivering a peritoneal dialysis cycle to a patient based on patient or system parameters. The systems and methods include various sensors, flow paths, and processors to adjust the dialysis parameters used to deliver peritoneal dialysis therapy, for a specific peritoneal dialysis cycle. For example, a first peritoneal dialysis cycle can provide data on patient or system parameters that can be used to adjust the dialysis parameters used to deliver a subsequent peritoneal dialysis cycle. One or more peritoneal dialysis cycles are contained in a particular peritoneal dialysis therapy session. Patient parameters can include patient blood pressure; volume of fluid removed; patient goal; blood solute level; effluent solute level; effluent temperature; effluent color or clarity; patient posture; tidal volume remaining in patient; and intraperitoneal pressure.

  • Patent number: 10716922
    Abstract: A fluid management system for moving bodily fluid accumulated due to ascites, pleural effusion or pericardial effusion is provided including an implantable pump coupled to an inflow catheter, an outflow catheter, and optionally an anti-clog catheter. The fluid management system facilitates removal of fluid from a body region, such as the peritoneum, pleural cavity or pericardial sac, where drainage is desired to another body region, such as the urinary bladder or the peritoneal cavity. The system includes clog resistant mechanisms such as clog resistant catheters and/or programmed routines for cycling fluid through inlet catheters in predetermined time intervals and/or responsive to sensed conditions to minimize the risk that inlet catheters become clogged due to, for example, tissue ingrowth and/or solid objects within accumulated fluid.

  • Patent number: 10576195
    Abstract: An apparatus for ultrafiltration of a patient being overhydrated due to congestive heart failure, comprising a tube set including a connector for connection to a patient line for access to the peritoneal cavity of the patient. A flow pump is arranged for addition and removal outflow and inflow (recirculation) of fluid from/to the peritoneal cavity. An osmotic agent peristaltic pump is arranged for replenishment of glucose solution to the fluid added to the peritoneal cavity for promoting ultrafiltration. The glucose is replenished intermittently for keeping a concentration of glucose substantially constant in the peritoneal cavity. The flow pump comprises a pressure chamber with rigid walls and a flexible pump bag arranged therein. An air pump pressurizes the chamber for outflow of fluid from the peritoneal cavity by a sub pressure and inflow of fluid to the peritoneal cavity by an overpressure, which pressures are maintained within safe limits.
