A mask includes a body having an interior surface defining a cavity shaped to receive a user's nose. An exterior surface of the body is exposed to an ambient environment. The body includes an inlet in fluid communication with the cavity and a one-way exhaust valve in fluid communication between the cavity and the ambient environment. A therapeutic substance dispenser is in fluid communication with the cavity. In one embodiment, a nasal aromatic decongestant is disposed in the therapeutic dispenser. A mask includes an upper nasal cavity separate from a lower oral cavity, with an inlet in fluid communication with only the upper nasal cavity. A medicament delivery assembly, and methods for the use thereof, are also provided.

A test fixture for testing aerosol provision devices may include a housing, a plurality of testing modules disposed at the housing where each of the testing modules includes a cavity configured to receive a portion of an aerosol provision device, and processing circuitry operably coupled to the testing modules. Each of the testing modules may be configured to interface with an assembly of a respective one of the aerosol provision devices to transition the assembly between an initial state and a transitioned state during a functional test controlled by the processing circuitry. The processing circuitry may be configured to conduct the functional test of at least two of the testing modules simultaneously.

An applicator can include a dispenser for dispensing an amount of a therapeutic composition, which can include an amount of sugar or sugar alcohol and an amount of an alkalizing agent. In some cases, the alkalizing agent can include L-Arginine. In some cases, 75% or more of the composition by weight has a comedogenicity rating of 3 or less on a scale of 0-5. The dispenser can also have a power supply configured to provide power through a contact tip of the dispenser to provide nerve stimulation, such as using vibration, heating, cooling, and/or electrical stimulation.

Systems and methods for fluid delivery into a ventilation system are disclosed. In an example, the technology relates to a fluid delivery system for delivery of aerosolized liquid. The fluid delivery system includes an injection tip having a set of orifices configured to aerosolize a liquid having certain properties. The injection tip may be couplable with components of a breathing circuit. For example, the injection tip may be couplable with components at or below a wye component (e.g., at a wye component or between the wye component and a patient), such as at the wye component or at an endotracheal tube multi-port connector. Alternatively, the injection tip may be integrated into a breathing circuit, such as at an endotracheal tube connector or at an endotracheal tube.

The invention relates to a small-volume nebulizer that is pre-filled with at least one unit-dose of medicine and hermetically sealed until use. The nebulizer may be sealed at the top with a removable cap that may be detached at the time of use and replaced with a patient connector. Likewise, the nebulizer may be sealed at the bottom with a bottom cap that is replaced with a gas source at the beginning of a therapeutic aerosol treatment.

A medicament delivery device (1) comprises an actuation mechanism by successive operation of which a predetermined number of unit doses of medicament can be dispensed. The device includes a locking mechanism for preventing further operation of the actuation mechanism after dispensing of said predetermined number of unit doses. The locking mechanism comprises a resilient member (51), a formation (18) with which the resilient member (51) is engageable to disable operation of the actuation mechanism, and a barrier member (20) that prevents engagement of the resilient member (51) and the formation (18) until said predetermined number of unit doses has been dispensed. The device (1) may be a dry powder inhaler.

Disclosed is a drug vaporization and inhalation device. The present invention is configured such that when an infected patient with asthma, a coronavirus, or the like inhales a particulate drug, the drug is contained in vaporized steam, and therefore, the drug can sufficiently arrive at the lungs of the infected patient with asthma, a coronavirus, or the like, without loss, thereby preventing a given amount of the drug from remaining in an inhalation container and improving the drug inhalation efficiency of the infected patient with asthma, a coronavirus, or the like along with prevention of excessive inhalation of the drug.

A vaporization device is provided having a plurality of pens each having a battery, a mouthpiece, and a ventilated end. A vaporization device is also provided which is disposable having a plurality of pens, each having a vaporization chamber containing a coil, a battery, a PCB, a sensor, and a tank containing e-liquid for vaporization in the pen vaporization chamber through the coil of the pen to create a vaporization product which is mixed in a vapor port of the device through which a plurality of vaporization products are delivered to a user through the mouthpiece of the device in a single vaporization event.

A humidification system including a conduit for carrying breathing gases, a pump to pressurize a liquid for injection into breathing gases, a liquid-injection nozzle protruding at least partially into the conduit and configured to inject liquid, pressurized by the pump, into the conduit; and a heated surface protruding into the conduit and positioned to vaporize the liquid injected by the nozzle, wherein the heated surface crosses a flow path of the breathing gases flowing through the conduit.

In one aspect, apparatus is provided for generating an inhalable medium. The apparatus has a container for holding a liquid and a heater for volatilizing liquid held in the container. The apparatus further has a chamber for receiving a material. The apparatus has an outlet. In use liquid volatilized by the heater passes, in the form of at least one of a vapor and an aerosol, through material received in the chamber to thereby entrain one or more constituents from the material to produce the inhalable medium which passes out of the outlet.
