A device for converting a consumable into an aerosol with high heat without burning the consumable by packaging the consumable around a susceptor for inductive heating so as to reduce the oxygen content within the consumable. The susceptor can be a flattened piece of steel wool. The encasement can be a coating applied to the consumable can be packaging inside an encasement through which the aerosol can pass. Efficiency of the to create a porous shell. The device can have a receiver with an airtight seal and an airflow controller to optimize the aerosolizing process. The device can also have a recognition system to detect a sign on the consumable-containing package an execute the appropriate administration protocol.

The present invention relates to systems and components for the rapid decompression of pneumothorax. The system includes a needle and novel indicator assembly. The indicator assembly includes valve assembly and color changing member that responds to CO2, visually indicating that the system has been placed in an appropriate location and that decompression is occurring.

Apparatus and methods are described for use with a portion of plant material that includes at least one active ingredient. A vaporizing unit includes a heating element configured to heat the plant material, and a sensor configured to detect an indication of airflow rate through the vaporizing unit. Control circuitry is configured to receive an indication of the airflow rate through the vaporizing unit, and, in response thereto, to determine a smoking profile that is desired by the user. The control circuitry drives the heating element to vaporize the active ingredient of the plant material by heating the plant material according to the determined smoking profile. The control circuitry dynamically updates the smoking profile in response to changes in airflow rate over the course of a smoking session. Other applications are also described.

A check valve includes an upper housing defining an inlet of the check valve, and a lower housing having a seating portion and defining an outlet of the check valve. The check valve further includes a chamber interposed between and defined by the upper and lower housings for fluidly connecting the inlet and the outlet, and a flexible diaphragm mounted in the chamber. The flexible diaphragm selectively permits fluid flow in a first direction, and prevents fluid backflow in a second direction opposite to the first direction. The flexible diaphragm includes a color changing material, and when the flexible diaphragm is seated on the seating portion and bent due to force of the fluid flowing in the first direction, the flexible diaphragm exhibits a color change.

Systems and methods for generating nitric oxide are disclosed. A nitric oxide (NO) generation system includes at least one pair of electrodes configured to generate a product gas containing NO from a flow of a reactant gas; and a controller configured to regulate the amount of nitric oxide in the product gas produced by the at least one pair of electrodes by utilizing duty cycle values of plasma pulses selected from a plurality of discrete duty cycles to produce a target rate of NO production based on an average of discrete production rates associated with each of the plurality of discrete duty cycles.

Disclosed herein is a device which is intended to deliver and maintain reduced pressure to body surfaces for application of reduced pressure wound therapy (RPWT) also known as negative pressure wound therapy (NPWT). During application of this type of therapy, a substantially airtight seal is formed around a section of tissue to be treated. This seal is formed by a dressing which provides fluid communication from a section of tissue to a reduced pressure source. Disclosed herein is a dressing system which is configured to enhance usability and functionality of this dressing. First, the system may be configured to allow full rotation of the fluid communication conduit to the reduced pressure source along the axis substantially normal to the dressing. Second, the system may be configured to include a one-way valve to prevent backflow of any drainage fluids. Third, the system may be configured with transparent windows covered by opaque flaps to allow inspection through the dressing. Fourth, the system may be configured to include an indicator which visually makes clear whether reduced pressure is being applied or not. Fifth, the system is configured to minimize the profile of the dressing system.

The present invention relates to an expression kit (2) for a breast pump (1) for extracting breast milk (101) from a human teat (102). The expression kit (2) comprises: a breast pump body (10) comprising a first pressure chamber (11) and a second pressure chamber (21); wherein the first pressure chamber (11) is configured for connection to a pressure unit (30) for generating a in the pressure chamber (11); wherein the second pressure chamber (21) comprises a breast-receiving funnel (22), a milk outlet (23) and a milk path (24) from the breast-receiving funnel (22) to the milk outlet (23); and wherein the first and the second pressure (11, 21) chamber are separated by a breathable membrane (50), which is gas-permeable and liquid-impermeable, for separating the first pressure chamber (11) from liquid in the milk path (24), wherein the breathable membrane (50) is a hydrophobic membrane. Further, the present invention relates to a breast pump (1).

A drug delivery system includes a reservoir and a drug delivery device coupled to the reservoir. The drug delivery device also may include at least one temperature-sensitive component and a lock having locked and unlocked states. The system further includes an output device, and a controller coupled to the lock and the output device. The controller may also include a temperature sensor, or may be coupled to the temperature sensor. The controller is programmed or configured to determine if the temperature of a drug in the reservoir or of the temperature-sensitive component exceeds an upper limit or is below a lower limit, and to activate the lock in either event. The controller is also programmed or configured to determine, directly or indirectly, if the temperature subsequently is between the upper and lower limits, and to unlock lock as a consequence.

An oxygen mask that incorporates chemical carbon dioxide (EtCO2) detectors to allow for the monitoring of patient respiration/ventilation without the use of clinical signs or electronic computer technology by providing a visual indication (through color change of the EtCO2 detectors) of the presence or absence of carbon dioxide.

Adherable, perforated patch worn inside or outside a facial mask delivering an inhalable product to airspace proximate to human respiratory airway. A disposable cover and disposable seal is removed, the patch is applied to inside or outside of a mask, with the mask worn over the mouth and nose. The patch delivers inhalable product to air proximate to the patch. Disposable cover, seal and tamper proof wrapper. Methods of manufacturing, distribution and utilization of the patch are disclosed.
