The heating element is a coil mounted within a chamber in thermal proximity to the solid inhalant. A quartz rod is mounted within the coil. A plunger is mounted within the cartridge to translate therein and compact the solid inhalant. In an alternative embodiment, dual channels and outlet ports are mounted in communication with an inlet port. In another embodiment, the cartridge is a split chamber cartridge with a split plunger mounted therein.
IN-LINE HEATING OF DIALYSIS FLUIDS
Dialysis systems and methods for operating dialysis machines (e.g., peritoneal dialysis machines) for conducting dialysis treatments are disclosed. The dialysis system may include a dialysis machine for transferring dialysate to a patient from a dialysate source. The dialysate may flow from the dialysate source through a cartridge or cassette (e.g., a disposable cartridge or cassette) positionable within the dialysis machine. The cassette includes a fluid flow channel. The dialysis machine includes a heating chamber for in-line heating of the dialysate in the fluid flow channel. The fluid flow channel is arranged and configured to provide turbulent flow of the dialysate through the fluid flow channel to provide increased heat transfer from the heating chamber to the dialysate.
ACOUSTIC DETECTION AND/OR ANALYSIS IN RESPIRATORY TREATMENT APPARATUS
An apparatus for treatment of a respiratory condition, the apparatus comprising: a pressure generator configured to generate a flow of breathable gas; an intermediate component pneumatically connected to an air delivery tube, the intermediate component comprising a port configured to facilitate propagation of sound outside of the intermediate component; a sensor attached externally to the intermediate component and located adjacent to the port of the intermediate component, the sensor configured to sense sound propagated through the air delivery tube; and a controller. The controller can be configured to: receive a sound signal generated by the sensor as a result of sensing sound during operation of the apparatus, analyse the received sound signal, and effect a response based at least in part on the analysing.
Dialysis system having inductive heating
A dialysis fluid system includes a dialysis fluid inlet; a dialysis fluid outlet; a pump positioned and arranged to pump dialysis fluid through the dialysis fluid inlet and the dialysis fluid outlet; and an inductive heater located between the dialysis fluid inlet and the dialysis fluid outlet, the inductive heater including a fluid flowpath positioned and arranged to receive non-heated dialysis fluid from the dialysis fluid inlet and to output heated dialysis fluid to the a dialysis fluid outlet, a conductive heater element located within the fluid flowpath so as to be or act as a secondary coil of a transformer, and a primary coil of the transformer located outside of the fluid flowpath and positioned so as to magnetically induce a current into the conductive heater element, causing the conductive heater element and surrounding fluid to heat.
HEMODIAFILTRATION SYSTEM WITH DISPOSABLE PUMPING UNIT
A hemodiafiltration system with a disposable pumping unit is disclosed. An example system includes a medical fluid pump actuator, a medical fluid heater, a blood filter and a disposable unit. The example disposable unit includes a medical fluid cassette portion including a medical fluid cassette housing configured to be operatively connected to the medical fluid pump actuator to pump medical fluid through the medical fluid cassette portion when the medical fluid cassette portion is in fluid communication with a medical fluid source. The example medical fluid cassette portion is also configured to be placed in fluid communication with the blood filter and with an extracorporeal circuit communicating with the blood filter, the fluid communication enabling hemodiafiltration to be performed. The example disposable unit also includes a heater bag configured to be placed in operable communication with the medical fluid heater and in fluid communication with the medical fluid cassette portion.
HUMIDIFICATION DEVICE AND RESPIRATORY ASSISTANCE DEVICE
A humidification device that includes a case containing a humidification space in which water vapor is introduced to a feed gas to be fed to a user. heating unit configured to acquire electric energy using an electromagnetic induction phenomenon to generate heat is disposed in the humidification space. The humidification device further includes a coil configured to transfer energy to the heating unit by the electromagnetic induction phenomenon, an insulating unit configured to spatially separate the heating unit and the coil to prevent electrical contact therebetween and a liquid supply unit configured to supply, to the heating unit, a liquid to be vaporized into the water vapor. This provides a humidification device that can be made smaller in size and lighter in weight, and that can quickly and sufficiently humidify a gas without heating an entire body of water to be stored, as well as a respiratory assistance device.
INHALATION DEVICE, METHOD, AND PROGRAM
The present invention provides an inhalation device with which it is possible to improve usability and promote users' safety and satisfaction with the inhalation device. An inhalation device according to the present invention is provided with a first member and a second member which is configured to be capable of being attached to and detached from the first member. This inhalation device includes: an active functional part which is provided to the first member; a passive functional part which is provided to the second member and which is capable of changing the state thereof according to the working of the active functional part; a sensor part which is provided to the first member and which detects a changed state of the passive functional part; and a control part which, on the basis of the detected state, determines whether the second member has been attached to the first member.
System And Method For Peritoneal Dialysis
The invention relates to a system of performing an evidence Dialysis modality of Batch, Tidal or a combination of both. The system: isolates cavity volume changes due only to ultrafiltrate; determines the volume of a patient cavity; determines a full cavity; determines an objective time to initiate an exchange; and determines an empty cavity. One or more combination of these features provide for evidence base Fill, Dwell, and Drain sequences. The system comprises: a cassette having a heated region and a sensor region for measurements. A valve manifold supplies a patient connection with fluid. A microprocessor receives pressure measurements, controls the heated region and activates a volumetric pump to deliver or extract discrete increments of the fluid to the cassette from bags. Filtering pressure measurements to remove rapid fluctuations determines an accumulated pressure in the patient cavity. The volume of fluid in the patient cavity correlates to the accumulated pressure.
Balancing Method and Balancing Unit Being Independent of Temperature Disturbance
This disclosure relates to a method for determining a fluid balance between a first volume flow in a first section of a fluid circuit and a second volume flow of a second section of the fluid circuit. The method may also include adjusting, assuming or detecting a first temperature in the first section of the fluid circuit and a second temperature in the second section of the fluid circuit, or detecting a temperature difference between the first and the second sections. The method may also include detecting a second volume flow in a second section of the fluid circuit and forming a balance from at least the first volume flow and a corrected value of the second volume flow. The corrected value is determined from the detected second volume flow and the second temperature and/or the temperature difference.
