The present invention provides a new inhaler device for the administration of inhalable liquids to a patient offering one or more advantages or improvements over known inhalers, particularly inhalers for the delivery of halogenated volatile liquids such as methoxyflurane for use as an analgesic.

An inhaler including a housing having a chamber to receive a valved canister and a stem block, and a mouthpiece in fluid communication with a passage of the stem block; and an actuation mechanism including configured to engage an outer surface of the stem block at a predefined angle relative to the longitudinal axis of the stem block to cause the downward movement of the stem block to activate the valve and release the aerosolizable liquid as the dose of the aerosolized spray out of the mouthpiece of the mechanical inhaler.

An atomizer is disclosed. The atomizer includes: a pump housing including an internal chamber extending in an axial direction of the pump housing and a mounting seat disposed at a first end of the pump housing and being in communication with the internal chamber; a seal disposed in the mounting seat, the seal including a sealing sleeve and a first bore in the sealing sleeve and coaxial with the internal chamber, and at least a part of the seal resting against a mounting surface of the mounting seat; a pressing member at least partially disposed within the mounting seat and resting against the seal to press and keep the seal in the mounting seat, the pressing member including a second bore coaxial with the internal chamber; and a plunger, a first end of the plunger being disposed within the internal chamber of the pump housing through the second bore of the pressing member and the first bore of the seal, and the first end of the plunger being capable of reciprocating in the internal chamber to pump fluid in or out of the internal chamber; wherein the pump housing, the pressing member and the plunger together define a sealing cavity to accommodate the seal.

A substance delivery device and methods to promote treatment regimen compliance. A beneficial substance and an addictive substance are administered from a device delivering the substances by a user inhaling vaporized or atomized beneficial substances and addictive substances.

Provided herein are intranasal fluid delivery devices and apparatus comprising a dispensing tip a shot chamber carrying a fluid, the shot chamber having a diaphragm at one end and a plunger at the other end, and an actuator connected to a push rod moveable toward the shot chamber.

A compact modular multifunctional inhalation device including a housing having an inlet port and an outlet port; a removable cartridge module adapted to seat within the housing, the cartridge including: a tray within the cartridge for holding a solid inhalant, a heating element mounted within the cartridge above and through the tray for heating the inhalant; and a removable modular electronic circuit adapted to seat within the housing to provide electrical current to the heating element. The heating element is a coil mounted within a chamber in thermal proximity to the solid inhalant. A quartz rod is mounted within the coil. A plunger is mounted within the cartridge to translate therein and compact the solid inhalant. In an alternative embodiment, dual channels and outlet ports are mounted in communication with an inlet port. In another embodiment, the cartridge is a split chamber cartridge with a split plunger mounted therein.

The present document describes a flow measuring apparatus for measuring a flow through a section of an inhalation apparatus, comprising at least one set of Pitot tubes first a second Pitot tube and streamlinings extending longitudinally parallel to the Pitot tubes and the set of Pitot tubes is configured for traversing entirely a lumen which define the section of the inhalation apparatus and are respectively fluidly connected to a differential pressure sensor for measuring a difference between a stagnation pressure and a static pressure within the flow measuring apparatus.

Aspects and embodiments of the present invention generally include a device for patient self-administration of a prescribed medication. The device makes available for administration the precise quantity of medication constituting a dose at times designated by a health care provider (HCP). Preferably, the device also detects and transmits information to a remote management system accessible to the HCP, including detected attempts to tamper with the device. Advantageously, HCPs may render oversight and control over the device and its use to mitigate risks associated with patients self-administering medication without in-person supervision. This control may include establishing prerequisites the patient must meet prior to a dose being made available, or remote deactivation of the device. This oversight by the HCP may include patient-specific and aggregate data analysis for optimization of treatment or evaluation of the safety and efficacy of a treatment. Furthermore, this oversight may be conducted via a web-based interface.

The present invention is a fluid dispensing apparatus, and method of use, e.g. for mouthwash and medicine, for dispensing a sterile liquid in single doses to prevent bacterial growth from un-used portions pored back into the apparatus. The apparatus has a hollow flexible cap enclosure surrounding a one-way valve inside of a bladder and a push rubber surface for liquid release. When the cap is removed, both the container body and the cap remain sealed from exposure to contaminates. Liquid is first dispensed from the container by inverting the container until a quantity of sterile liquid collects in the cap. The container is then positioned in an upright position and the fluid filled cap is removed from the container. The cap is then inverted again and a pushbutton pressed to dispense sterile liquid from a cap spray nozzle without requiring the user's lips to touch the cap.
