  • Patent number: 10265451
    Abstract: A fluid handling cassette, such as that useable with an automated peritoneal dialysis (APD) cycler device or other infusion apparatus, may include a generally planar body having at least one pump chamber formed as a depression in a first side of the body and a plurality of flowpaths for a fluid that includes a channel. A patient line port may be arranged for connection to a patient line and be in fluid communication with the at least one pump chamber via at least a first one of said flowpaths, and an optional membrane may be attached to the first side of the body over the at least one pump chamber. In one embodiment, the membrane may have a pump chamber portion with an unstressed shape that generally conforms to the depression of the at least one pump chamber in the body and is arranged to be movable for movement of the fluid in a useable space of the at least one pump chamber.

  • Publication number: 20190099534
    Abstract: Components for a medical infusion fluid handling system, such as an APD system, in which one or more lines (such as solution lines), spikes or other connection ports may be automatically capped and/or de-capped. This feature may provide advantages, such as a reduced likelihood of contamination since no human interaction is required to de-cap and connect the lines, spikes or other connections. For example, a fluid handling cassette may include one or more caps that cover a corresponding spike and include a raised and/or recessed feature to assist in removal of the cap from the cassette. A solution line cap may include a hole and recess, groove or other feature to engage with a spike cap and enable removal of the cap.

  • Patent number: 10244659
    Abstract: A thermal distribution assembly for an electronic device is disclosed. The electronic device includes an enclosure defined by a metal band and a non-metal bottom wall formed by glass, sapphire, or plastic. In this regard, the enclosure may include a relatively low thermal conductivity. However, the thermal distribution assembly provides heat transfer capabilities that offset thermal conductivity losses by using a non-metal bottom wall, and also provides added structural support. The thermal distribution assembly may include a first layer, a second layer, and a third layer. The first and third layers provide structural support, while the second layer provides a relatively high thermally conductive layer.

  • Publication number: 20190060629
    Abstract: Improvements in fluid volume measurement systems are disclosed for a pneumatically actuated diaphragm pump in general, and a peritoneal dialysis cycler using a pump cassette in particular. Pump fluid volume measurements are based on pressure measurements in a pump control chamber and a reference chamber in a two-chamber model, with different sections of the apparatus being modeled using a combination of adiabatic, isothermal and polytropic processes. Real time or instantaneous fluid flow measurements in a pump chamber of a diaphragm pump are also disclosed, in this case using a one-chamber ideal gas model and using a high speed processor to obtain and process pump control chamber pressures during fluid flow into or out of the pump chamber. Improved heater control circuitry is also disclosed, to provide added or redundant safety measures, or to reduce current leakage from a heater element during pulse width modulation control of the heater.

  • Publication number: 20190046714
    Abstract: A medical treatment system, such as peritoneal dialysis system, may include control and other features to enhance patient comfort and ease of use. For example, a peritoneal dialysis system may include patient line state detector for detecting whether a patient line is primed before it is to be connected to the patient. The patient line state detector can also the ability to detect whether a patient line has been properly mounted for priming. Both patient line presence/absence and fill state can be determined using an optical system, e.g., one that employs a single optical sensor.

  • Publication number: 20180361048
    Abstract: A medical treatment system, such as peritoneal dialysis system, may include control and other features to enhance patient comfort and ease of use. For example, a peritoneal dialysis system may include a control system that can adjust the volume of fluid infused into the peritoneal cavity to prevent the intraperitoneal fluid volume from exceeding a pre-determined amount. The control system can adjust by adding one or more therapy cycles, allowing for fill volumes during each cycle to be reduced. The control system may continue to allow the fluid to drain from the peritoneal cavity as completely as possible before starting the next therapy cycle. The control system may also adjust the dwell time of fluid within the peritoneal cavity during therapy cycles in order to complete a therapy within a scheduled time period.

  • Publication number: 20180256803
    Abstract: A medical infusion fluid handling system, such as an automated peritoneal dialysis system, may be arranged to de-cap and connect one or more lines (such as solution lines) with one or more spikes or other connection ports on a fluid handling cassette. This feature may reduce a likelihood of contamination since no human interaction is required to de-cap and connect the one or more lines and the one or more spikes. For example, the automated peritoneal dialysis system may include a carriage arranged to receive the one or more lines each having a connector end and a cap. The carriage may move along a first direction so as to move the connector ends of the one or more lines along the first direction, and a cap stripper may be arranged to engage with the caps on the the one or more lines on the carriage. The cap stripper may move in a second direction transverse to the first direction, as well as to move with the carriage along the first direction.

  • Publication number: 20180083322
    Abstract: An electronic device having a battery assembly is disclosed. Unlike traditional battery assemblies that include rectilinear electrodes with two sides of equal length, the battery assemblies described herein may include electrodes having a shape/configuration resembling an L-shape electrode used to form chemical reactions in order to generate electrical energy. However, other shapes/configurations are possible. The shape/configuration of the housing of the battery assembly confirms to the shape/configuration of the electrodes. Further, in order to accommodate an internal component (such as a circuit board assembly), the shape of the battery assembly provides additional space in the electronic device. In order to form the electrodes, the electrodes may undergo a die cutting operation. Also, the housing may include a channel, or reduced dimension, that accommodates a flexible circuit in the electronic device that passes over the battery assembly at the channel.

  • Patent number: 9861732
    Abstract: A medical treatment system, such as peritoneal dialysis system, may include control and other features to enhance patient comfort and ease of use. A fluid trap of a peritoneal dialysis cycler may have a valved connection to a vacuum source or a positive pressure source. The fluid trap can be connected to the vacuum source in order to sealingly engage a flexible membrane of a pumping cassette to a control surface of the cycler during a therapy. Any fluid entering a space between the membrane and control surface can be drawn away and collected in the fluid trap. The fluid trap alternatively can be connected to a positive pressure source in order to aid in separating the membrane from the control surface to facilitate removal of the pumping cassette from the cycler. The fluid trap may include a liquid detection sensor.
