Abstract: A medication infusion system includes a housing with an adapter interface to couple with a medication container (syringe or vial). A pressure source expels gas to deliver fluid to a patient, while a pressure sensor and control unit regulate infusion parameters. A reference chamber with additional sensors enables volume estimation using pressure-volume-temperature relationships. A medication transfer device includes interfaces to couple to the infusion pump and secure the vial, with piercing elements defining inlet and outlet channels. The device may include valves, a gas filter, and a bubble eliminator with a hydrophobic membrane. The system enables direct-from-vial medication delivery without intermediate containers.

Abstract: An infusion device includes a medication container interface to couple with a first portion of a medication container. The medication container has a second portion having an orifice and a medication chamber that encapsulates fluid which is disposed between the first and second portions of the medication container. A pressure chamber is formed when the first portion of the medication container is interfaced with the medication container interface. A pressure source, when active, expels gas and/or fluid within the pressure chamber to apply a pressure to a surface of the medication container causing fluid within the medication chamber to be expelled out of the orifice. A pressure sensor measure pressures within the pressure chamber. A control unit in communication with the pressure source and the pressure sensor and sends signals to the pressure source to control infusion parameters based, at least in part on, the measured pressure.

Abstract: A medication infusion system includes a housing with an adapter interface for coupling with a syringe or vial. A pressure source expels gas to deliver fluid to a patient, while a pressure sensor and control unit regulate infusion parameters. Some variations include a reference chamber with additional sensors for volume estimation using pressure-volume-temperature relationships. A medication transfer device for vials includes interfaces for the pump and vial, piercing elements with inlet and outlet channels, valves, a gas filter, and a bubble eliminator with a hydrophobic air-permeable membrane. The system enables direct-from-vial medication delivery without transfer to intermediate containers.

The first interface can be on a first end have a shape and size to couple to an infusion pump. The second interface can be on a second end and have a shape and size to secure the vial. The one or more piercing elements can define both at least a portion of (i) an inlet channel in fluid communication with a pressure source generated by the infusion pump when the first interface is coupled to the infusion pump and (ii) an outlet channel in direct fluid communication with an infusion set delivering medication from the vial to a patient.

Abstract: Methods, systems, and devices for protection of semiconductor devices from optical scanning are described. A semiconductor device may implement one or more material layers that are configured for refracting photonic emissions, which may impair an ability to use such photonic emissions for adverse analysis of the semiconductor device. For example, a semiconductor device may include one or more layers that include geometric structures that are configured to refract photonic emissions from the semiconductor device. Additionally, or alternatively, a semiconductor device may include one or more layers with different doping configurations (e.g., with different refractive indexes) that are configured to refract photonic emissions from the semiconductor device.

Abstract: A device, system and method are provided for controlling the rate of infusion of fluids during infusion therapy using non-electric infusion devices. Rotation of a flow regulator dial causes an orifice connected to the inlet to modify its position relative to a particular one or more orifices or groove portions, the characteristics of which provide a certain flow rate characteristic. The flow regulator allows for the Infusion pump to Infuse at a rate that may be varied during use by the user. Additionally, the flow regulator is made from a material selected to operate under a wide range of pressures, from 5-40 PSI, making the flow regulator compatible with pressurized devices, such as, a non-electric pump.

During boot of the second container, the second container is configured to generate a cryptographic key that is based on a measurement or characteristic of process code of the second container, a configuration parameter of the second container, or any combination thereof.

Abstract: A mechanical infusion system includes a housing having top and bottom portions. A pair of sliding slots extend transversely along the bottom portion. A hinge causes the top portion to connect with the bottom portion to form a closed position and separate from the bottom portion to form an open position. The housing forms engagement and syringe receiving cavities to respectively receive a flange and barrel of a syringe. A movable pusher is biased towards the engagement cavity so as to apply force to a plunger of the syringe. The infusion system also includes linkages configured to move transversely in a first direction upon opening of the top portion to cause the pusher to move away from the engagement cavity and move transversely in a second, opposite direction upon closing of the top portion to allow the pusher to retract towards the engagement cavity within the sliding slots.

Abstract: The present invention provides methods of detecting responsiveness of cancers to immunotherapies and determining which treatment to use with a particular cancer. The methods include obtaining a sample from the subject and detecting the expression level of keratin 17 (K17) in the sample. Low levels of K17 expression indicates that the cancer is responsive to the immunotherapy and high levels of K17 expression indicate that the cancer is not responsive to immunotherapy and that other methods of treating the cancer should be used.
