The present invention is generally related to a device and method for sanitizing a medical instrument with ozone, in particular the invention relates to a system, method and a device for sanitizing a continuous positive airway pressure (CPAP) device. The device has an ozone compartment, an ozone operating system and one or more ozone distribution lines that distribute ozone to a continuous positive airway pressure device. The device may further include a heater adapter unit to connect heating systems in CPAP devices while distributing ozone to sanitize the CPAP device in accordance with the present invention.

Technologies (e.g., devices, systems and methods) for sanitizing reservoirs are described. In some embodiments, the technologies include a sanitization gas system and a connector unit or a hole in the reservoir wall, configured to connect a supply line to the reservoir. The connector unit may include an inlet passageway for supplying sanitizing gas (e.g., ozone) into the reservoir.

A nitric oxide delivery device including a valve assembly, a control module and a gas delivery mechanism is described. An exemplary gas delivery device includes a valve assembly with a valve and circuit including a memory, a processor and a transceiver in communication with the memory. The memory may include gas data such as gas identification, gas expiration and gas concentration. The transceiver on the circuit of the valve assembly may send wireless optical line-of-sight signals to communicate the gas data to a control module. Exemplary gas delivery mechanisms include a ventilator and a breathing circuit. Methods of administering gases containing nitric oxide are also described.

In an aspect, there is provided an apparatus which may include a cartridge and a vaporizer body. The cartridge may include a cartridge body defining a reservoir configured to contain vaporizable material, a vaporizing assembly positioned within the cartridge body. The vaporizer body may include a receptacle configured to receive at least a portion of the cartridge, and control circuitry comprising at least one processor and at least one memory disposed within the vaporizer body, the at least one memory including instructions which when executed cause operations comprising: storing an event indicative of detection of an insertion of the cartridge into the vaporizer body; requesting, from the cartridge, cartridge information; receiving, in response to the request, the cartridge information stored at the cartridge; and configuring, based at least in part of the received cartridge information, the vaporizer device for vaporizing of the vaporizable material.

An aerosol delivery device is provided that includes at least one housing structured to retain an aerosol precursor composition. The device includes an atomizer, and a microprocessor configured to operate in an active mode in which the control body is configured to control the atomizer to activate and produce an aerosol from the aerosol precursor composition. And the device includes a heart rate monitor including a plurality of biopotential electrodes affixed to the housing and configured to obtain biopotential measurements from a user, and including signal conditioning circuitry configured to produce an electrocardiogram signal from the biopotential measurements. The microprocessor is coupled to the signal conditioning circuitry and further configured to control operation of at least one functional element of the aerosol delivery device based on the electrocardiogram signal or a heart rate of the user calculated therefrom.

A portable hemodialysis system is provided including a disposable cartridge and a reused dialysis machine. The disposable cartridge includes a dialyzer, and a dialysate flow path and a blood flow path which flow in opposing directions through the dialyzer. The disposable cartridge includes pressure and fluid flow sensors for measuring the pressure and fluid flow in the dialysate flow path and blood flow path. In addition, the disposable cartridge possesses pump actuators (but not pump motors) for pumping dialysate and blood through their respective flow paths. Preferably, the disposable cartridge includes a filter for removing waste products from dialysate.

Systems and methods for pumping milk from a breast, wherein the milk is expressed from the breast under suction and milk is expulsed from the pumping mechanism to a collection container under positive pressure.

In some embodiments, a system includes a cartridge assembly and a pen assembly. The cartridge assembly includes a mouthpiece assembly and a bracket cartridge assembly. The mouthpiece assembly includes a mouthpiece component defining a mouthpiece opening and an outer housing defining a vapor outlet and including a recessed sidewall portion. The pen assembly includes a pen housing and a bracket assembly configured to engage with the bracket cartridge assembly of the cartridge assembly such that a temperature of a coil of a wick assembly of the cartridge assembly may be increased such that a carrier material disposed near the coil may be vaporized by the coil. When the cartridge assembly is engaged with the pen housing, the recessed sidewall portion of the outer housing and an inner surface of the pen housing form a fluid path from the vapor outlet to the mouthpiece opening.

A non-burning type flavor inhaler, comprises: a housing having an airflow path that continues from an inlet to an outlet; an atomizer configured to atomize an aerosol source without burning; a sensor including a capacitor, the sensor outputting a value indicating electric capacitance of the capacitor, the electric capacitance changed depending on a puff action of a user; and a controller configured to detect a start or an end of a puff duration on the basis of an output value that is output from the sensor. The controller detects the start or the end of the puff duration when an inclination formed by two or more of the output values has a predetermined sign and when an absolute value of the inclination having the predetermined sign is larger than a predetermined value.
