  • Patent number: 11491287
    Abstract: The present invention provides for the integration of drug dispersion methods into a drug or medicine delivery system. The drug dispersion methods used include shear (e.g., air across a drug, with or without a gas assist), capillary flow or a venturi effect, mechanical means such as spinning, vibration, or impaction, and turbulence (e.g., using mesh screens, or restrictions in the air path). These methods of drug dispersion allow for all of the drug in the system to be released, allowing control of the dosage size. These methods also provide for drug metering, fluidization, entrainment, deaggragation and deagglomeration. The present invention also provides for the integration of a drug sealing system into the device. The drug sealing system provides a way of blocking the migration of drug from one area of the package to another.

  • Patent number: 11291811
    Abstract: A medicant delivery method is to introduce a fluid into a container by flowing along a pressure-in pathway and out to the container. As a flow speed is stable, a connecting channel is plugged to enter the fluid to the pressure-out pathway. The fluid flows along the pressure-out pathway and then out into the container to convey the medicant at a container bottom out of the container. This method can provide more stable and more balanced forcing to gently carry the medicant all the way out of the container. Thereupon, contamination at an endoscope by the medicant bounced back from a target tissue to block vision of the endoscope can be avoided. Thus, medicant administration (hemostatic medicant for example) can be more accurate, continuity of an endoscopic surgery can be improved, performance in hemostasis can be raised, and also the total surgery time can be reduced.

    Abstract: A breath actuated nebulizer for administration of an inhaled medication to a patient is provided with a generally cylindrical body in a horizontal orientation to the patient. Within the body is a Venturi configured to nebulizer a liquid medication in a reservoir. Within the body is a shaft integrated with a baffle and diaphragm that slides horizontally in response to the breathing of a patient. During inhalation by the patient, the diaphragm flexes shifting the baffle over the Venturi, allowing nebulization to occur. When the patient exhales, the diaphragm flexes to a default position in which the baffle is distal to the Venturi, thereby stopping the nebulization. The diaphragm is biased to rest in this default position until the patient inhales again.

    Abstract: Xenon based biosensors have the potential to detect and localize biomarkers associated with a wide variety of diseases. The development and nuclear magnetic resonance (NMR) characterization of cage molecules which encapsulate hyperpolarized xenon is imperative for the development of these xenon biosensors. We acquired 129Xe NMR spectra, and magnetic resonance images and a HyperCEST saturation map of cucurbituril (CB6) in whole bovine blood. We observed a mean HyperCEST depletion of 84% (n=5) at a concentration of 5 mM and 74% at 2.5 mM. Additionally, we collected these data using a pulsed HyperCEST saturation pre-pulse train with a SAR of 0.025 W/kg which will minimize any potential RF heating in animal or human tissue.

  • Patent number: 11020549
    Abstract: A dry powder inhalation device is disclosed. In one optional aspect, the device includes a housing, a base plate, a receptacle for a medicament and a mouthpiece. The base plate is engageable with the housing to form a main space with a main air inlet. The mouthpiece includes an inner conduit connected to its outlet and is engageable with the base plate to fluidly connect the inner conduit to the receptacle. The receptacle is fluidly connected to the main space, so that upon inhalation by a user, air can be drawn through the main air inlet into the main space and onward through the receptacle into the inner conduit. The mouthpiece and the base plate form an auxiliary space with an auxiliary air inlet, wherein the auxiliary space is fluidly connected to the main space.

  • Patent number: 11000667
    Abstract: A breathing apparatus has a first delivery device for adding a volume of a substance to a gas flow, the delivery device having a gas inlet and a gas outlet. A unit monitors a presence of the substance in a gas downstream the delivery device using a first sensor unit at the gas outlet that provides a first measurement value based on an acoustic property of a gas in a first conduit. A second sensor unit at the gas inlet provides a second measurement value based on an acoustic property of a gas present in the second conduit. A control unit determines the presence of the substance based on the first measurement value or based on a comparison of the first measurement value and the second measurement value.

  • Patent number: 10994116
    Abstract: An infusion pump includes a reusable housing unit, a disposable reservoir, and a cap fit on the reservoir, wherein the cap includes a conduit for fluid communication. An aseptic connector assembly includes first and second occlusions in the reservoir and the cap. A pull assembly extends from the aseptic connector assembly and forms the first and second occlusions. The pump has three states. In a storage state, the reservoir is separate from the housing unit and the first and second occlusions cooperate to occlude a wet path extending from the reservoir through the conduit in the cap. In a ready state, the reservoir is applied to the housing unit but the wet path is still occluded. In a use state, the reservoir is applied to the housing unit, the first and second occlusions are removed from the aseptic connector assembly, and the wet path is opened for communication.

  • Patent number: 10987474
    Abstract: An aerosol delivery system that includes an aerosol generator that aerosolizes a fluid for delivery to a patient as a patient inhales. The aerosol delivery system includes a pump coupled to the aerosol generator that pumps the fluid to the aerosol generator, and a breath sensor that emits a signal as the patient breathes. A controller couples to the aerosol generator, the pump, and the breath sensor. In operation, the controller receives the signal from the breath sensor, controls a flow of fluid to the aerosol generator in response to the signal, and controls the aerosol generator to start aerosolizing the fluid before the patient inhales.

  • Patent number: 10974006
    Abstract: The invention relates to a face mask arrangement for alternately administering a gas I containing nitrous oxide and a gas II devoid of nitrous oxide to a patient, comprising a face mask, two inlet flow lines I and II for gas I and a gas II, respectively, which flow lines end in a breathing interface, and an outlet flow line for evacuation of exhaled gas. The two inlet flow lines merge into a common inlet part. Each of the inlet flow lines I and II comprises an inlet valve I and II, each of which is capable of opening in response to inhalation and of closing in response to exhalation. The arrangement comprises a switching means enabling switching between inhalation through inlet flow line I and inlet flow line II depending on the patient's immediate need of gas I or gas II.
