Provided is a nasal drop device which can simply and easily administer an appropriate amount of a solution to a specific site in the nasal cavity without waste. The nasal drop device 100 includes: an ejection portion 104 that ejects droplets into the nasal cavity; and a control portion that acquires suitability information indicating whether or not a current relative angle between a reference line indicating the posture of the face of a user who puts the nasal drop device 100 in the nose and a reference line indicating the posture of the nasal drop device 100 is suitable for the nasal drop, and controls the ejection operation of the ejection portion 104 according to the suitability information.

Modular smoking devices that vaporize certain materials, such as tobacco or cannabis are disclosed. The technology provides for intelligent ignition, combustion, or vaporization of given material at the appropriate temperatures that prevent generation of harmful and unwanted byproducts. According to one embodiment, the modular smoking device comprises a self-contained combustion chamber to hold the material, a combustion mechanism integrated with the self-contained combustion chamber, and an energy source, such as a rechargeable battery, to power the combustion mechanism. The combustion mechanism is configured to provide targeted combustion of the material, where the active ingredients generated upon the combustion are consumed by inhaling a smoke or vapor resulting from the combustion or vaporization. The self-contained combustion chamber includes a lighterless combustion mechanism such as a piezoelectric lighter or a lighter sold under TESLA COIL LIGHTERS® that is designed to arc an electric discharge through the material in the self-contained combustion chamber.

There is provided a mesh for use in forming droplets of liquid in a nebuliser, the mesh comprising a first portion (22) made of a first material having a plurality of holes passing therethrough; and a second portion (26) made of a second material that is in contact with the first portion (22), the second portion (26) having a corresponding plurality of holes passing therethrough, the plurality of holes in the second portion forming nozzles (28) for an outlet side of the mesh; wherein the first material has a higher density than the second material.

Provided is a smart inhaler, headset and wearable smart mask configured to operate as an air ionizer and a controlled multi-liquid atomizer. The smart mask, headset and smart inhaler use a mature technology to deliver various types of liquid solutions to different applications from health care, drug delivery, immunization to recreational and gaming uses. In addition, the smart mask and headset contain multiple actuators to provide haptic feedback to the areas around the mask and headset. The headset, smart mask and inhaler have a direct communication path to a smart device or it can be a smart device by itself; its various environmental and gas sensors act as a feedback mechanism. The detection level of the organic and non-organic VOC gas emitted when exhaling can be communicated and stored for analysis purposes. The detected gas can be regenerated on the same smart mask or a different remote smart mask.

An in-line droplet delivery device and related methods for delivering precise and repeatable dosages to a subject for pulmonary use is disclosed. The in-line droplet delivery device includes a housing, a mouthpiece, a reservoir, an ejector mechanism, and at least one differential pressure sensor. The in-line droplet delivery device is automatically breath actuated by the user when the differential pressure sensor senses a predetermined pressure change within housing. The in-line droplet delivery device is then actuated to generate a plume of droplets having an average ejected particle diameter within the respirable size range, e.g, less than about 5-6 μm, so as to target the pulmonary system of the user. the droplet delivery device is configured in an in-line orientation in that the housing, its internal components, and various device components (e.g., the mouthpiece, air inlet flow element, etc.) are orientated in a substantially in-line or parallel configuration (e.g., along the airflow path) so as to form a small, hand-held device.

A method of beautification using hydrogen inhalation capable of promoting improvement of skin condition by regular intake of a high-concentration hydrogen-containing gas air into a body by oral or nasal inhalation under spontaneous breathing, and a high-concentration hydrogen inhalation device appropriate for use in the method of beautification using hydrogen inhalation are provided. According to the method of beautification using hydrogen inhalation, regular oral or nasal inhalation of a high-concentration hydrogen-containing gas generated from hydrogen generating means can non-therapeutically promote improvement of skin condition. In addition, the high-concentration hydrogen inhalation device for use in the method of beautification using hydrogen inhalation includes: hydrogen generating means that generates and releases hydrogen; and hydrogen transporting means that guides the high-concentration hydrogen-containing gas to the nose and mouth of a human body, the high-concentration hydrogen-containing gas being a mixture of hydrogen released from the hydrogen generating means and environmental air.
