A volume of a wound is estimated using a dynamic pressure response measured during instillation of fluid to the wound using a negative pressure wound therapy system. A previously estimated wound volume may be used to detect and prevent overfill of fluid to the wound during future instillation events. For example, real-time pressure measurements may be compared to model data representative of expected pressure at a wound having a volume equal to the previously estimated wound volume, with instillation being stopped if the observed pressure varies from the expected pressure. A comparison of a total volume of fluid instilled to the wound may also be compared to the previously estimated wound volume to prevent overfill. The comparison of wound volume estimated based on an instillation event may also be compared to a wound volume estimated using other methods to provide a higher confidence wound volume estimate.

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.

The internal volume of the main body is less than 1000 ml. The concentration of NO in the gaseous mixture NO/N.sub.2 is between 15000 and 25000 ppmv. The gas pressure in the internal volume is below 15 bar, measured at 23° C. Installation for delivering gas to a patient, including such a gas cartridge, a NO supply device fed by the gas cartridge, and a medical ventilator feeding a patient circuit which has an inhalation branch fed by the NO supply device. Use for treating patients suffering from pulmonary hypertension or hypoxia.

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 medical fluid pump with an upper housing shell, a lower housing shell and a front lid pivotably hinged to the lower housing shell. A printed circuit board with essential control devices is arranged in the upper housing shell, and an energy storage is provided and fixed in the lower housing shell.

Disclosed herein are embodiments of a wound treatment apparatus with electronic components integrated within a wound dressing. In some embodiments, a wound dressing apparatus can comprise a wound dressing. The wound dressing can comprise an absorbent material, an electronics unit comprising a negative pressure source, the electronics unit integrated within the wound dressing and at least partially encapsulated by a flexible film. The flexible film can comprise a window or aperture configured to permit fluid communication between the absorbent material and the negative pressure source.

A medical wetness sensing device includes a base adapted to be disposed on a wearer of the medical wetness sensing device. The base includes a first electrical conductor and a second electrical conductor electrically insulated from the first electrical conductor. The first electrical conductor includes a hinge portion enabling a first portion of the first electrical conductor to deflect, at the hinge portion, relative to a second portion of the first electrical conductor. The medical wetness sensing device includes a controller electrically connected to the first electrical conductor and the second electrical conductor. The controller is configured to detect a presence or an absence of a medical fluid electrically connecting the first and second electrical conductors.

Described is an injector system for implementing a split bolus injection procedure. The injector system includes a processor and a non-transitory storage medium having programming instructions stored therein that, when executed by the processor, enable the injector system to operate as a parameter generation system for use in determining parameters associated with a split bolus injection protocol via which injection of the contrast agent by the injector system is controlled. The split bolus injection protocol includes at least a loading injection and a diagnostic injection, wherein the loading injection is performed before the diagnostic injection, and wherein a pause separates the loading injection from the diagnostic injection. Also described is a method for patient imaging using a split bolus injection technique and a system having an imaging device and the injector system described above.

An evaporator unit for an inhaler, in particular for an electronic cigarette product, comprises an electrically operable, in particular planar, heating body which has an inlet side and an outlet side, and a plurality of microchannels which each extend from the inlet side to the outlet side through the heating body, the heating body being designed to evaporate, by applying a heating voltage, liquid transferred through the microchannels. A porous and/or capillary wick structure is arranged on the inlet side of the heating body, which structure rests flat against and in contact with the heating body and covers all of the microchannels on the inlet side.

Systems, devices, and techniques are disclosed for administering and tracking medicine to patients and providing health management capabilities for patients and caregivers. In some aspects, a method includes receiving one or more analyte values associated with a health condition of the patient user; receiving contextual data associated with the patient user obtained by the mobile computing device, where the obtained contextual data includes information associated with a meal; determining a medicine metric value associated with an amount of medicine active in the body of the patient user; autonomously calculating a dose of the medicine without input from the user based at least on the one or more analyte values, the medicine metric value, and the information associated with a meal; and continuously displaying the calculated dose of the medicine.
