Selective sealing cartridge
Cartridges have a cartridge body configured to store a formulation, a formulation valve disposed in the cartridge body, and an air valve disposed in the cartridge body. The cartridge is configured to dispense the formulation through the formulation valve when the formulation valve and the air valve are each in an open state, and to not dispense the formulation when the formulation valve and the air valve are in a closed state.
Rotary valve pump for automatic drug compounder
Various aspects of the subject disclosure relate to a compounder system having a cartridge that includes controllable fluid pathways. One or more rotary piston pump/valves may be used to move fluid and/or gasses through the various fluid pathways of the cartridge. For example, the cartridge may include a dedicated rotary piston pump/valve for each process that moves fluid and/or gas through the cartridge. When turning, the rotary piston pump/valve acts as a pump to move the fluid or gas, and when the rotary piston pump/valve stops turning, it effectively acts as a shutoff valve, preventing any fluid flow. Magnetic couplers for the cartridge may be provided on a pump head of the compounder system.
AEROSOL SUPPLY DEVICE
An aerosol supply device includes: an accommodating part (cartridge) configured to accommodate a liquid; an atomization unit configured to atomize the liquid to generate an aerosol; a discharge port configured to discharge the generated aerosol to the outside of the aerosol supply device; and a volatilization preventing part (solenoid valve or duckbill valve) capable of opening and closing a passage (first passage or second passage) through which at least one of the liquid or the aerosol flows between the accommodating part and the outside of the aerosol supply device.
AEROSOL SUPPLY DEVICE
This aerosol supply device is provided with: an accommodating section (cartridge) that accommodates a liquid; an atomizing unit that atomizes the liquid to generate an aerosol; and an atomizing amount adjusting unit (gyro sensor and control unit) that adjusts the atomizing amount of the atomizing unit. The aerosol supply device is characterized in that the atomizing amount adjusting unit (gyro sensor and control unit) stabilizes the atomizing amount regardless of the inclination of the aerosol supply device within at least a certain range.
SERVICEABLE RESPIRATOR SYSTEM WITH CONFIGURABLE COMPONENTS
There is provided a respirator for supplying clean air for a wearer. The respirator comprises a face assembly comprising an oronasal mask configured to seal against and cover a nose region and a mouth region of the wearer. The face assembly may be configured to be interchangeable on the respirator between a half-face assembly and a full-face assembly. The respirator comprises a securing headgear releasably securable with the face assembly, the securing headgear assembly configured to secure the respirator on a head of the wearer. The respirator comprises a facepiece assembly for supplying the wearer with air for inhaling and releasing air exhaled by the wear, the facepiece assembly releasably securable with the face assembly. One or more of the face assembly, the facepiece assembly, or the securing headgear are configured to be released from the respirator, sterilized, and releasably resecured with the respirator.
Peritoneal dialysis systems, devices, and methods
A peritoneal dialysis device includes a disposable tubing set that includes a fill line with a patient access connector at one end and a dialysis fluid receiving end opposite the patient access connector end. The device also includes a fill-side pressure measuring sensor attached at the fill end and forming a disposable component of the tubing set and a patient-side pressure measuring sensor located at the fluid receiving end. The patient-side and fill-side pressure measuring sensors are adapted for measuring pressure in the fill line at the respective ends thereof. The device also includes a controller configured to regulate a rate of flow in the fill line responsively to a signal from the at least the patient-side pressure measuring sensor.
Automated medical sample collection and testing for providing blood coagulation indication
A sample collection and testing device for analyzing blood is provided that includes a controller, a fluid flow pathway, a pump configured to move fluid through the fluid pathway, and an optical fluid measurement element configured to measure a light intensity of the fluid in the fluid flow pathway. The controller is configured to: start the pump to move a blood sample in the fluid flow pathway, receive a signal from the optical fluid measurement element indicating a detection of a leading edge of the blood in the fluid flow pathway, stop the pump to stop the moving of the blood in the pathway, receive a plurality of light intensity measurements from the optical measurement element, each light intensity measurement measured at a corresponding point of time, and provide a mapping of the light intensity measurements into an indication of a coagulation of the blood sample over a time period.
Device and method for tempering the flow of liquids in medical devices
The present invention relates to an apparatus for flow tempering medical irrigation fluids and to a method carried out with the aid of this apparatus.
SYSTEM FOR PERITONEAL DIALYSIS AND EXTRACORPOREAL BLOOD TREATMENTS
A dialysis system is disclosed that enables a patient to undergo both peritoneal dialysis and extracorporeal blood treatments. The system includes a base unit and a blood treatment unit configured to perform extracorporeal blood treatments on a patient. The blood treatment unit includes a user interface operable with a controller for displaying a calendar of days in which an extracorporeal blood treatment is scheduled to be performed. The base unit includes a base unit controller that is programmed to receive information indicative whether a peritoneal dialysis treatment or the extracorporeal blood treatment is to be performed. The base unit controller operates first software instructions when the base unit uses a first fluid stored in a fluid container when the peritoneal dialysis treatment is selected or operates second software instructions when the base unit uses a second, different fluid from an online source when the extracorporeal blood treatment is selected.
Pumping cassette
A pumping cassette including a housing having at least two inlet fluid lines and at least two outlet fluid lines. At least one balancing pod within the housing and in fluid connection with the fluid paths. The balancing pod balances the flow of a first fluid and the flow of a second fluid such that the volume of the first fluid equals the volume of the second fluid. The balancing pod also includes a membrane that forms two balancing chambers. Also included in the cassette is at least two reciprocating pressure displacement membrane pumps. The pumps are within the housing and they pump the fluid from a fluid inlet to a fluid outlet line and pump the second fluid from a fluid inlet to a fluid outlet.
