Pump cassettes, wound-treatment apparatuses and methods. In some embodiments, a pump cassette comprises: a pump body having a pump chamber, an inlet valve in fluid communication with the pump chamber, and an outlet valve in fluid communication with the pump chamber; a diaphragm coupled to the pump body such that the diaphragm is movable to vary a volume in the pump chamber; and an identifier configured to store one or more properties of the pump cassette such that the identifier is readable by an automated reader to determine the one or more properties. In some embodiments, the pump cassette is configured to be removably coupled to a wound-treatment apparatus having an actuator such that the actuator can be activated to move the diaphragm.

A priming valve includes a fluid flow path, a fluid inlet configured to couple to a fluid outlet of a fluid channel including at least one sensor configured to characterize at least one attribute of a fluid, a fluid outlet, a valve seat, and a connector. The connector engages the valve seat to prevent fluid flow via the fluid flow path. The connector is configured to move relative to the valve seat in response to a threshold pressure within the fluid flow path to allow the fluid to flow via the fluid flow path. A flow sensor sub-assembly for sensing flow of a fluidic medicament may include a priming valve and at least one sensor of a fluid port configured to characterize at least one attribute of a fluid within an administrable fluid source. A method for readying a fluid sensor may use a priming valve.

A method may include receiving, from a volume meter at a pump configured to deliver medication to a patient, data indicative of a volume of a medication present in a syringe inserted in the pump. A first counter may be updated, based on the data, in response to the medication being delivered to the patient as a first dose type. A second counter may be updated, based on the data, in response to the medication being delivered to the patient as a second dose type. The volume of the medication delivered to the patient may be determined based on the first counter and/or the second counter. An electronic alert may be sent to a mobile device in response to one or more anomalies being present in the volume of the medication delivered to the patient. Related methods and articles of manufacture, including apparatuses and computer program products, are also disclosed.

Medication delivery devices are provided having a housing comprising a reservoir sized sufficiently to hold medication, a dose button being rotatable relative to the housing to select a dose size of the medication for an injection, a printed circuit board, a switch mounted to the printed circuit board, and a controller in communication with the switch. The controller is configured to generate a first count of a set of signals using a first counting technique, generate a second count of the set of signals using a second counting technique, and determine, based on the first and second count, reliability data of the first and/or second count. The controller can connect, using a wireless communication module, to a remote computing device to wirelessly communicate with the remote computing device over an unencrypted wireless communication channel, and transmit, using the wireless communication module, encrypted data to the remote computing device.

The present technology relates to systems and/or methods for enabling a respiratory device to be configured when a clinician or healthcare professional is remote from the respiratory device. One form provides a method of configuring a respiratory device, the respiratory device comprising a processor configured to control operation of the respiratory device in accordance with a plurality of operating parameters. The method comprises determining a combination of settings for the device from an identifier sent to the device, the identifier corresponding to the combination of settings, and configuring the respiratory device accordingly. Another form provides a method of verifying the configuration of the respiratory device by outputting an identifier corresponding to the combination of settings for the device, and determining the settings from the identifier.

A method for site assessments of a catheter insertion site and/or dressing includes: scanning the catheter insertion site and/or dressing with an image capture device and/or sensor; selecting a patient baseline site location and skin tone; recording a baseline condition using a computing device; determining a site assessment rate using a computing device; prompting a clinician to make a site assessment of the catheter insertion site and/or dressing using a computing device; and recording site assessment information in an electronic medical record using a computing device.

Systems, methods and apparatuses for aerosolizing all or substantially all plant matter, medications, flavors, smells, liquid and/or other material to be aerosolizing are disclosed. Embodiments of the invention comprise an aerosolization chamber sealed except for two or more conduits, a first conduit coupled to a source of fully or almost fully oxygenated gas, a heating element capable of heating the aerosolization chamber to a temperature above a combustion temperature, a second conduit configured to transport aerosolized gases and elements out of the chamber and, in one implementation, at least one valve positioned in the second conduit preventing the flow of atmospheric air into the vaporization chamber. In some instances, the first gas substantially clears the vaporization chamber of atmospheric air prior to reaching combustion temperature. A second gas containing oxygen may be intermixed with the vaporization gases and vaporized elements proximal to the combustion chamber.

A respiratory pressure therapy system for providing continuous positive air pressure to a patient via a patient interface configured to engage with at least one airway of the patient. The system includes: a flow generator configured to generate supply of breathable gas for delivery to the patient via the patient interface; at least one sensor; a display; and a computing device. The computing device is configured to: receive sensor data that is based on measured physical property of the supply of breathable gas; control, based on the received sensor data, the flow generator to adjust a property of the supply of breathable gas; receive, an input indicating assistance is needed with using the patient interface; receive one or more images of the patient with the patient interface; analyse the received one or more images; and based on the analysis, display instructions for positioning the patient interface.
