  • Patent number: 10933190
    Abstract: A rolling diaphragm syringe includes a proximal end having an end wall, a distal end having an open-ended discharge neck, a sidewall extending along a longitudinal axis, and a piston engagement portion protruding proximally from a central portion of the end wall and configured for engagement with a piston of a fluid injector. The piston engagement portion has a stem with a first end attached to the end wall, a second end extending proximally from the first end, and at least one protrusion that protrudes radially outward. The sidewall is flexible and rolls upon itself when acted upon by the piston such that an outer surface of the sidewall is folded in a radially inward direction as the piston is advanced from the proximal end to the distal end, and unfolded in a radially outward direction as the piston is retracted from the distal end to the proximal end.

  • Patent number: 10926113
    Abstract: A portable chemical oxygen generator for delivering oxygen to a patient is described. The generator includes a housing containing a reaction chamber. Within the reaction chamber is a quantity of a peroxide adduct. A valve is provided with a lower portion of the valve in fluid communication with the reaction chamber. An upper portion of the valve is in fluid communication with a reservoir that holds a quantity of an aqueous solution. An internal chamber is formed within the valve by releasable seals that separate the internal chamber from the upper portion of the valve and a lower portion of the valve. The internal chamber holds a quantity of a peroxide-decomposing catalyst. The generator also includes a valve actuator. Operation of the valve actuator releases the seals in the valve and creates a fluid path from the reservoir through the internal chamber into the reaction chamber.

  • Patent number: 10857345
    Abstract: A medical connector assembly for establishing a fluid connection between a first medical device and a second medical device includes a multi-use connector and a plurality of single-use connectors connected in series. The multi-use connector has a proximal end opposite a distal end along a longitudinal length thereof. The plurality of single-use connectors each have a proximal end opposite a distal end along a longitudinal length thereof. The distal end of the multi-use connector is releasably connected to the proximal end of a first of the serially-connected single-use connectors. When a second of the serially-connected single-use connectors is disconnected from the first single-use connector, the first single-use connector remains connected to the multi-use medical connector as a sterility retaining cover.

  • Publication number: 20200341801
    Abstract: Systems and methods for cloud-based file sharing, where templates are provided for creating workflow instances which enable the sharing of managed objects. Reusable workflow templates are stored in the repository of a cloud-based file sharing system as objects that define components of the workflow, or placeholders for these components. A user instantiates a workflow instance from one of the templates and configures the workflow instance to identify content objects or forms, tasks related to the content objects, and users assigned to perform the tasks. The workflow instance is stored as an object in the repository. Users assigned to tasks are authorized through the workflow instance to access the content objects or forms to perform the tasks.

  • Publication number: 20200334211
    Abstract: An interface server (e.g., Web Application Open Platform Interface (WOPI) server) is communicatively connected to an information management (IM) server and to an online application server which acts as a client of the interface server. When a user wishes to open, create, or edit a document in an online application hosted by the online application server, the interface server is called, instead of the IM server which manages the document at the backend of an enterprise computing network. The interface server is configured for obtaining a working copy of the document from the IM server and providing the working copy to the client. The client provides the working copy to the online application for display on the user device. When the work is done, the working copy is sync'd back through the interface server to the IM server as a new draft and deleted by the interface server.

  • Patent number: 10677676
    Abstract: Systems, methods, and devices for positioning, orienting, and/or aligning a stress sensor assembly are provided. Raw stress signals, which can correspond to stress in the target, can be generated by detecting a magnetic flux that travels through the target. The raw stress signals can be sensitive to an alignment of the sensor relative to the target. In order to minimize measurement error, the stress sensor can be properly aligned relative to the target prior to taking a stress measurement. Sensor alignment can involve adjusting a yaw, pitch, and/or roll of the sensor, measuring the raw stress signals, attenuating the detected magnetic flux, and measuring the raw stress signals again. When the stress sensor is properly aligned, a change in a size of a gap between the sensor and a surface of a target can result in approximately equal changes in the raw stress signal.

  • Publication number: 20200121860
    Abstract: A fluid injector system for delivering a multi-phase fluid injection to a patient and methods of fluid delivery is disclosed. Methods of creating and using a multi-aspect fluid path impedance model of the injector system are used. Modeling and adjustment of factors that affect impedance and prevent or reduce backflow, reduce the likelihood of fluid flow rate spikes and provide more accurate flow rates and mixing ratios of fluids may be repeated or happen essentially continuously during an injection. The adjustments may be determined before the injection or determined and/or adjusted during the injection. The determination may include sensor feedback commonly used in injectors such as pressure and position feedback as well as other sensors. In all cases, the user can be notified of adjustments through on-screen notices and/or through the recordation of the injection data by a control device of the injector at the conclusion of the injection.

  • Patent number: 10560763
    Abstract: Examples of the present disclosure describe smart sensor technology. In an example, a smart sensor module may connect to a sensor using two connectors. Similarly, an external device may connect to the smart sensor module using two connectors, such that, in a pass-through operating state, a signal from the sensor is passed through the smart sensor module to the external device, thereby causing the smart sensor module to appear as an ordinary sensor and enabling the external device to sense the signal from the sensor. In another example, the smart sensor module may have an alternate operating state, wherein additional functionality is enabled, including, but not limited to, communication with a controller, activation of a light emitting diode (LED) or other indicator, or the retrieval and/or storage of information. The operating state may be selected based on the manner in which the external device connects to the smart sensor module.
