Disclosed is a mask-free system and method for inducing anesthesia in a pediatric patient. In a preferred embodiment, calming and then anesthetic gases are administered through a mouthpiece with a distraction device, such as an inflatable bag or balloon or an audible siren whistle. This system avoids the anxieties and trauma of the pediatric patient and their parents that have been associated with mask-based induction methods.

Illustrative embodiments of new and useful systems and methods for reduced-pressure therapy are described. One example embodiment is a manually-actuated pump for applying reduced-pressure therapy. The pump generally comprises a charging chamber, a regulated chamber, and a regulator passage between the charging chamber and the regulated chamber. A valve body controls fluid communication through the regulator passage, and a regulator spring may be engaged with the valve body to bias the valve body against a differential between a pressure in the regulated chamber and an ambient pressure. The regulator passage may have a bore size adapted deflect the valve body to cause an audible indication of a leak.

An inhalation device including a housing, which encloses a liquid reservoir in which the liquid is stored before discharge, and an applicator head with a nebulization chamber and an applicator piece connected thereto, wherein the applicator piece is designed either as a mouthpiece, to be received in the mouth of a patient, or as an inhalation mask, to sealingly cover the mouth, the nose, or the mouth and the nose. The inhalation device furthermore has a discharge channel which connects the liquid reservoir to the applicator head. The inhalation device includes at the end of the discharge channel, a nozzle plate with a large number of nozzle openings which serve to generate an inhalation mist and through which the liquid from the liquid reservoir is conveyed into the nebulization chamber.

A device for targeted delivery of a substance to an airway may include a conduit and at least two applicators. The conduit may include a proximal end and a bifurcated distal portion having two distal ends. Each applicator may be coupled with one of the distal ends of the conduit and may be configured to direct the substance out of the applicator toward one of two sides of an airway. A method for targeted delivery of a substance to an airway may involve advancing a substance delivery device into the airway, contacting two sides of the airway with at least two applicators of the substance delivery device, such that each applicator contacts the airway near a glossopharyngeal nerve and/or a superior laryngeal nerve on each of the two sides of the airway, and delivering the substance through the applicators to contact the airway along the two sides.

Described are gas flow disruption alarms. The alarms can include a gas inlet; a gas outlet configured to couple to a gas delivery device; and a vibration member between the gas inlet and the gas outlet configured to produce an audible sound when a gas delivery device is removed from the gas outlet.

A cleaning catheter insertable into a ventilation tube and an input module are provided, the input module coupled to the cleaning catheter and including (i) an inflation module, including an inflation chamber and a one-way air inlet valve; (ii) a flow regulator, configured to assume first and second fluid-control states; and (iii) a mechanical user control element, which is configured (a) to mechanically and non-electrically set the fluid-control states, (b) to assume first and second configurations, and (c) to mechanically and non-electrically increase pressure in an interior of an inflation chamber of the cleaning catheter during a transition of the mechanical user control element from the first configuration to the second configuration. The one-way air inlet valve is arranged to allow air to flow into the inflation chamber during a transition of the mechanical user control element from the second configuration to the first configuration.

A portable artificial respirator for a pet comprises: a mask part configured to cover the mouth and nose of the pet and having a mouth opening and a nose opening formed in the front end portion thereof; and an air injection part detachably coupled to the mask part, wherein the air injection part communicates with the mask part while at least a part thereof is inserted into the mouth opening of the mask part when the air injection part is coupled to the mask part. The portable artificial respirator enables a person to safely carry out artificial respiration without bringing his/her mouth into direct contact with a pet's mouth to prevent the pet who recovers consciousness from attacking the person who is providing the artificial respiration and can be assembled, disassembled, and carried in an easy and simple manner.
