  • Patent number: 11129971
    Abstract: A chest drainage system, including a circulation assembly having an intake for taking fluid into the system and an exhaust for exhausting fluid out of the system. An intake flow device is configured to selectively control fluid flow through the intake and an exhaust flow device is configured to selectively controlling fluid flow through the exhaust. The circulation assembly has a first configuration and a second configuration such that transitioning between the first and second configurations during operation of the circulation assembly displaces at least a portion of fluid within the system with fluid from outside the system via the intake and the exhaust. A sensor is arranged in fluid communication with the fluid within the system and configured to detect a concentration of a reference fluid in the fluid in the system.
    Type: Grant

  • Patent number: 10201315
    Abstract: Devices, computer readable programs and methods determine a patient parameter, including volume and/or flow rate of a fluid draining through a drain tube from a chest cavity of a patient, by using at least one pressure value at an end of the drain tube associated with a fluid collection canister and at least one pressure value within the drain tube at a location distant from the collection canister. The pressure values are processed with a non-linear solver to determine the patient parameter.

  • Patent number: 8547239
    Abstract: A fluid medicament delivery device includes a patient attachment unit, containing the fluid medicament, and an indicator unit adapted to be detachably coupled to the patient attachment unit. A method for monitoring the fluid medicament includes independently setting a flow rate of a fluid medicament with the patient attachment unit. A pressure and/or a flow rate of the fluid medicament is sensed with a sensor located in a separate indicator unit in a sensing mode. A status of the fluid medicament delivery device is determined based at least in part on the pressure and/or the flow rate.
