  • Publication number: 20190325068
    Abstract: The present disclosure relates to systems, methods, and non-transitory computer readable media for generating digital responses to digital queries by utilizing a classification model and query-specific analysis models. For example, the disclosed systems can train a classification model to generate query classifications corresponding to product queries, conversational queries, and/or recommendation/purchase queries. Moreover, the disclosed systems can apply the classification model to select pertinent models for particular queries. For example, upon classifying a product query, disclosed systems can utilize a neural ranking model (trained based on a set of training product specifications and training queries) to generate relevance scores for product specifications associated with a digital query.

  • Publication number: 20190275240
    Abstract: A drip chamber for an infusion tube, including: a first end including a drip tube; a second end including an exit port; and a wall connecting the first and second ends and including an interior surface with a hydrophobic portion. The drip chamber includes a space enclosed by the interior wall and the first and second ends. The hydrophobic portion of the interior surface repels liquid contacting the hydrophobic coating. The hydrophobic portion of the interior surface enables light to refract through the hydrophobic portion and the wall in the same manner as is the case when the hydrophobic portion is not present on the interior surface.

  • Patent number: 10300193
    Abstract: A controller for a programmable medical pump is configured to select a drug library file that corresponds to a received medication name and determine a number of times status information is received within a designated time period from a current time during an infusion therapy. The example controller is also configured to determine if the number of times the status information is received comports with an accumulated medication dosage limit using a dose per administration program parameter. Responsive to the number of times the status information is received matching or exceeding the accumulated medication dosage limit, the controller is configured to prevent another administration of the medication until enough time has passed such that the number of times the status information has been received within the designated time period from the current time is less than the accumulated medication dosage limit.

  • Publication number: 20180283369
    Abstract: An infusion pump is provided, including a specially programmed microprocessor, a flow sensor for measuring flow from a source of fluid through an output tubing, a pumping section including a plurality of fingers in operational relationship to the output tubing, an outlet valve associated with the output tubing, and a first actuator configured for sequentially displacing the plurality of fingers to displace fluid through the output tubing. An inlet valve is disposed between the pumping section and the source of fluid; and a second actuator is also included. For detection, by the flow sensor, of flow above a predetermined level, the microprocessor is configured for one of: closing the outlet valve independently of the inlet valve using the first actuator; and closing the inlet valve independently of the outlet valve using the second actuator.

  • Patent number: RE47452
    Abstract: A method for immobilizing dyes and antimicrobial agents on a polymeric cover or housing for a medical device is disclosed and described. The surface may be that of a catheter, a connector, a drug vial spike, a bag spike, a prosthetic device, an endoscope, a surface of an infusion pump, a key pad, a touch screen or a handle. The surfaces may also be one or more of those associated with a infusion of a medicament or dialysis treatment, such as peritoneal dialysis or hemodialysis, where it is important that the working surface for the dialysis fluid be sterile. These surfaces include connectors for peritoneal dialysis sets or for hemodialysis sets, bag spikes, dialysis catheters, and so forth. A method for determining whether a surface has been sterilized, and a dye useful in so indicating, is also disclosed.
