Systems, methods, and devices are described for heating nebulizer adapters. In certain embodiments, a nebulizer adapter includes a cup having an interior wall defining a gas mixing chamber, an exterior wall, and a fluid cavity disposed between the interior wall and the exterior wall. The nebulizer adapter also includes an inlet port having a fluid lumen in fluid communication with the fluid cavity and a breathing gas inlet lumen in fluid communication with the mixing chamber. The nebulizer adapter further includes an outlet having a breathing gas outlet lumen, and a drain port in fluid communication with the mixing chamber and having a drain lumen that passes from the interior wall to the exterior wall of the cup.

A medicinal diffuser system for patients is provided and includes a nasal cannula, a flow stream vessel and a mount assembly. The medicinal diffuser system is mountable over a patient's head and permits a steady flow of air while administering a medicinal agent. The medicinal diffuser permits a steady flow of air to flow into the patient's nasal cavity while administering a medicinal agent.

A system for administering an aerosolized liquid to a respiratory system of a patient includes a patient interface and an aerosolization device. The patient interface includes a laryngeal mask airway comprising a tracheal tube and a laryngeal cuff located at a distal end of the tracheal tube. The aerosolization device includes a liquid delivery device configured to deliver a liquid, a gas flow generator configured to generate a gas flow, and a sprayer. The sprayer includes a catheter configured to extend into the tracheal tube. The catheter includes a first lumen configured to receive the gas flow at a proximal end, a second lumen configured to receive a flow of the liquid at the proximal end, and a spray tip at a distal end configured to aerosolize the flow of the liquid using the gas flow. The first lumen extends through the second lumen.

A mask 100 configured to substantially surround an opening of a patient's airway. The mask has a mask body 101 comprising a filter 103 configured to filter a fluid from a patient facing side of the mask to a non-patient facing side 105 of the mask, wherein the non-patient facing side faces an ambient environment AE. The mask has an interfacing feature 121 configured to, in use, interface with a patient interface 10100, 10100 provided on the patient 10020.

Present invention is related to a ventilator adapter and auxiliary chamber thereof. The ventilator adapter of the present invention comprises a T-shaped flow guiding adapter and an auxiliary chamber detachably connected thereto. The T-shaped flow guiding adapter contains a guiding valve that can retractably close or open its opening. The auxiliary chamber is a cylindrical hollow tubing with open ends at both sides, and a chamber partition extended into the interior of the auxiliary chamber, separating the chamber at least partially into two chambers. The present invention is able to be adapted with the conventional ventilator pipeline by using the T-shaped flow guiding adapter for connecting any suitable ventilatory medicine with the auxiliary cavity. When the ventilatory medicine is administrated, the present invention is able to guide the gas flow within the ventilator pipeline reaching into the space of the auxiliary cavity and carrying the ventilatory medicine toward the patient successfully with high amount of medicine doses for better treatment result.

A safety system for a breathing apparatus for delivery of an anesthetic agent having an anesthetic agent vaporizer having a reservoir for containing a liquid anesthetic agent has a reservoir for containing a liquid medical agent, a port for filling the reservoir with the liquid anesthetic agent, and a sensor device for sensing a filling action of the port. A change of position of a lid covering the port is can be detected, or insertion of a fill vessel into said the port is can be detected. Thus safety of said the equipment is improved by being able to de-pressurize the reservoir before opening a filling valve for communication of the port with the interior of the reservoir.

An evaporator device for evaporating a substance may include an evaporator, two electrical connections, a blocking conductor, and an electrical current path for an electrical supply of the evaporator. The evaporator may include an electrically conductive evaporator ceramic with a receiving structure that receives the substance during operation. The electrical current path may extend through the two electrical connections, the evaporator ceramic, and the blocking conductor. The evaporator ceramic may be configured to homogeneously provide heat in a thermal operating range between an operation starting temperature and an operation end temperature. The blocking conductor may be heat-transmittingly connected to the evaporator ceramic. The blocking conductor may configured such that, upon exceeding the operation end temperature, an electrical resistance of the at least one blocking conductor abruptly increases.

Methods and devices for capturing and analyzing aerosolized particles in exhaled breath characteristic of a respiratory disease to enable rapid, low-cost point of care assays for several diseases including respiratory tract diseases such as COVID-19 are disclosed. The disclosed methods and systems selectively capture aerosolized particles using a packed bed column. The captured particles are then eluted using solvents and analyzed using analytical devices including MALDI-TOFMS.

A disposable nasal air moisturizing device is removably attached to a nasal cannula to release a moisturizing liquid into a breathing gas and a patient's nasal airway. The intranasal sponges and moisturizing liquid prevents and treats both abrasions from the nasal cannula and excessive drying of the mucosa. This reduces the incidence of nosebleeds in patients using supplemental nasal oxygen.

A sedation device has a housing divided internally into a ventilator chamber and an associated evaporator chamber which overlap and are separated by a filter mounted between the chambers and forming a common gas-permeable dividing wall between the chambers. An inlet port is provided at one end of the ventilator chamber at a top of the housing for connection to a patient ventilator in use. An outlet port on the evaporator chamber can be connected via a breathing tube to a patient. An evaporator is mounted within the evaporator chamber for delivery of a volatile sedative into the evaporator chamber during use.
