There is a ventilator for mechanical ventilation during a breathing cycle including an inhalation cycle and an exhalation cycle. The ventilator is configurable to be in fluid communication with a supply of a first fluid. The ventilator includes an inhalation pathway and an exhalation pathway. A first fluid injector is in fluid communication with the supply of the first fluid for injecting the first fluid. The inhalation pathway receives the first fluid injected by the first fluid injector. A controller is operatively connected with the first fluid injector and programmed to selectively actuate the first fluid injector to inject the first fluid, which is received within the inhalation pathway such that an inhalation pressure in the inhalation pathway is within a predetermined range during the inhalation cycle.

An anesthetic equipment storage and waste air management module configured to housing electronic and electromechanical surgical equipment including a system to measure and record administration of one or more IV medications or fluids for IV administration. The module can include a housing having a lower section and a tower-like upper section, wherein the lower section is configured to house unrelated waste heat-producing electronic and electromechanical surgical equipment. The module can also include a cowling that substantially confines waste heat generated by the unrelated waste heat-producing electronic and electromechanical surgical equipment, and can include a system for measuring and recording the administration of the one or more IV medications and fluids.

Methods and systems for automating surgical procedures in model organisms. The system includes a user input panel, a trained computer vision system, a server, and articulated robotic arm. The system may further include an analytical scale, an anesthesia chamber, a tube labeling system, a tissue freezing system, and a biohazard waste disposal system. The computer vision system communicates with the robotic arm to coordinate tissue collections and common research procedures such as injections via recognition models related to detection, identification, localization, and classification. The central server provides rapid synchronization of data between the local machine and a cloud account system for real-time data analytics. The anesthesia chamber provides standardized administration of anesthesia, the sample labeling system provides 2D barcoded labels according to user input, and the tissue freezing and waste disposal systems enable storage of samples and removal of carcasses following tissue collection, fully automating the necropsy.

Examples of a module for housing unrelated electronic and electromechanical equipment for use during surgery. The module can include a lower section and a tower-like upper section. The lower section can house unrelated electronic and electromechanical equipment. The tower-like upper section can be located on top of the lower section. A water-resistant cowling can enclose at least a portion of the lower section and the tower-like upper section. A cartridge containing one or more ultraviolet-C producing lights can be protectively housed within the tower-like upper section. The cartridge containing one or more ultraviolet-C producing lights can be configured to emerge upward from a top of the tower-like upper section to substantially seat itself on the top of the tower-like upper section when activated allowing the ultraviolet-C light to disinfect the patient and staff-contacting upper surfaces of the equipment in the operating room.

A portable oxygen concentrator retrofit system and method in which an existing portable oxygen concentrator may be retrofitted to output an enriched oxygen gas at a flow rate suitable for use in a patient ventilation system without the need for an external source of compressed gas.

Systems and methods for producing nitric oxide (NO) to be used in medical applications are provided. In some embodiments, systems and methods are provided for a NO generator that is capable of generating a desired concentration of NO to be provided to a respiratory system for inhalation by a patient.

An anesthesia device configured to measure the hydrogen concentration in an anesthesia gas containing a hydrogen gas includes: an anesthesia gas preparation circuit configured to generate anesthesia gas by mixing an air or an oxygen mixture air with a vaporized anesthetic; a closed circuit-type or semi-closed circuit-type respiratory circuit including a gas circulation passage configured to circulate the hydrogen-containing anesthesia gas containing the hydrogen gas and the vaporized anesthetic; and a hydrogen concentration measurement circuit configured to measure the hydrogen concentration in the hydrogen-containing anesthesia gas in the gas circulation passage, wherein the hydrogen concentration measurement circuit includes: an anesthetic removing member having a removability of the vaporized anesthetic in the hydrogen-containing anesthesia gas; and a hydrogen concentration measuring instrument provided on the secondary side of the anesthetic removing member.

Described herein are improved assisted ventilation interfaces along with methods and uses thereof. The interfaces comprises a hood embodiment with altered design aspects to decrease or even avoid the risk of leakage and potential viral transmittance along with providing other benefits. In one aspect, the patient interface comprises a hood with a free-breathing valve and an integral viral filter. The free-breathing valve and viral filter may be separate to or integral to the exhaust port. In a further embodiment multiple branches may be used from the exhaust port with multiple viral filters. In a further embodiment, an internal pressure gauge may be used. In a further embodiment dual air sources may be used.

An apparatus for administering a respirable gas to an individual includes a body receivable against a facial area for enclosing a respiratory organ, a vacuum hose, and a scavenger valve. The body is cup shaped, and includes a first side and a second side. An inhalation member extends from the first side of the body. An exhalation member extends from the second side of the body. The vacuum hose is for coupling a vacuum source to the exhalation member. The scavenger valve is coupled to the vacuum hose. The inhalation member is for administering respirable gas into the body, the exhalation member is for exhausting exhaust gas from the body into the vacuum hose, and the scavenger valve is for exhausting exhaust gas therethrough from the vacuum hose to an atmosphere.

A breathing assistance apparatus and method of controlling a breathing assistance apparatus is disclosed. Particularly, the breathing assistance apparatus is controlled such that it has a drying cycle to enable drying of the tubing that supplies gases to a user and prevent the harboring of pathogens within the tube. The drying cycle is preferably operated automatically by internal controllers in the apparatus. However, it may be manually activated by pressing a button on the apparatus. The drying cycle is preferably activated at the end of a user's treatment session.
