A method includes forming an antimicrobial blend including an antimicrobial additive combined with a polymer, and forming a medical device with the antimicrobial blend, wherein a surface of the medical device exhibits antimicrobial properties.

Methods and apparatuses (e.g., systems, devices, etc.) for delivering a nebulized drug agent in the nasal passages concurrent with the lungs.

An essential oil diffusion mechanism, including: a housing having an accommodation chamber; and a separator that divides the accommodation chamber into an upper chamber and a lower chamber and includes a horizontal partition plate and vertical partition plates. The horizontal partition plate defines at least one interconnecting hole. An upper surface of each vertical partition plate is spaced apart from a chamber wall of the upper chamber to form an upper interconnecting aperture. Each vertical partition plate defines an interconnecting reflux hole. A lower surface of each baffling plate is spaced apart from the horizontal partition plate to form a lower interconnecting aperture. The interconnecting hole, the upper interconnecting aperture, the lower interconnecting aperture, and the air outlet are sequentially arranged in communication to form an air outlet channel. The upper interconnecting aperture, the reflux hole, and the interconnecting hole are sequentially arranged in communication to form a reflux channel.

There is provided an aerosol generating system, the system comprising: aerosol generating means; aerosol delivery means; and an aerosol guiding device (1). The aerosol guiding device comprises a chamber having an air inlet (14) and an air outlet (12) and the aerosol delivery means is configured such that aerosol is introduced from the aerosol generating means into the chamber in use. An airflow route is defined from the air inlet to the air outlet so as to convey the aerosol to the air outlet, and the relative dimensions of the air inlet and the air outlet are selected to provide pressure control means for controlling the pressure differential between the air inlet and the air outlet.

An apparatus and method for providing a nebula or aerosol to a patient is described. In one aspect, the nebulizer is composed of a minimum number of parts to reduce complexity for automated or human assembly. The nebulizer may include an inhalation valve, exhalation valve and biasing member integrated into a single diaphragm structure that may be connected with an actuator and inserted into a housing for controlling nebulization of a medicine to a patient in response to the patient's breathing or in a continuous nebulization mode.

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.

Disclosed is a family of intranasal spray dispensers for administering uniform low doses of desmopressin so as to achieve safe antidiuresis in human patients. The dispensers of the invention may be used in the treatment of nocturia, primary nocturnal enuresis, incontinence, urinary frequency, diabetes insipidus, or any disease or syndrome where desmopressin therapy is useful or where safe temporary suppression of urine production may lead to beneficial health effects or increased convenience in voiding control.

A respiratory therapy apparatus is operable to deliver multiple types of therapy to a patient. The apparatus includes a main housing and a nebulizer tray that selectively attaches to a bottom of the main housing. The apparatus also includes a filter housing unit having an antenna surrounding a pneumatic passage and a transponder chip coupled to the antenna. The main housing has also has an antenna that surrounds a respective pneumatic passage of a main outlet port of the apparatus. The main housing includes a reader that controls communication between the antennae. The main housing of the apparatus also has a pivotable hose support plate, a firmware upgrade port underneath part of the top wall of the housing, and a graphical user interface (GUI) that displays various user inputs for control of the apparatus and that displays various alert conditions that are detected.

A respiratory device comprising a housing enclosing a chamber and an orientation indicator moveable with respect to the housing between a first position indicative of an orientation of the housing predetermined to be suitable for operation of the respiratory device, and a second position indicative of an orientation of the respiratory device predetermined to be less suitable for operation of the respiratory device. The orientation indicator is positioned in a location on the respiratory device visible to a user during the operation of the respiratory device.
