A small animal anesthesia system is provided, including a compressor, an anesthetizing gas generator and an anesthesia platform. The compressor has a first outlet and a first intake. The anesthetizing gas generator has a second outlet and a second intake. The first outlet of the compressor is connected to the second intake of the anesthetizing gas generator to supply gas, so that an anesthetizing gas is generated. The anesthesia platform includes a bearing plate, an anesthetic mask and a first anesthesia chamber. The anesthetic mask is configured to cover the face of the small animal, and connected to the second outlet of the anesthetizing gas generator, such that the small animal is anesthetized by the anesthetizing gas generated by the anesthetizing gas generator. The first anesthesia chamber is disposed on the bearing plate, and connected to the first intake of the compressor to recycle the anesthetizing gas.

An anesthetic vaporizer system includes a reservoir containing anesthetic agent, an agent level sensor measuring an agent level of the anesthetic agent in the reservoir, a display, and a controller. The controller is configured to receive agent level measurements from the agent level sensor over a time period, and determine the anesthetic agent is being added to the reservoir from an agent source based on the agent level measurements over the time period. A filling status is determined based on the agent level measurements and a filling status indicator is displayed based on the determined filling status.

A method of forming a stream having a therapeutic concentration of nitric oxide (NO) is disclosed, along with an apparatus and system suitable to accomplish this method.

A relay administration device 50 for use in connection to a nitric oxide administration device 20 which supplies NO generated from air, includes an NO densitometer 506, a flowmeter 507 or pressure gauge 504, a control unit 600 which calculates a dosage of NO to be administered to a patient based on an NO concentration measured by the NO densitometer 506 and a value of the flowmeter 507 or the pressure gauge 504, and a two-way valve 505 which is configured to increase a flow rate when the calculated dosage is less than a predetermined value and to decrease the flow rate when the calculated dosage is greater than a predetermined value.

A display device of an anesthesia machine which is communicable with at least one syringe pump that is an external apparatus displays an anesthesia information display screen. When a call switch is operated, a syringe pump information display screen indicating operation information of the syringe pump is displayed on the display device, in addition to the anesthesia information display screen.

Described herein are examples of pharyngeal respirators. Pharyngeal respirators may include a connection end having a first outer width, a flange disposed on the connection end having a second outer width greater than the first outer width, and a socket disposed on the flange. The connection end may be insertably disposed within a receiver of a pharyngeal breathing tube. The flange may not fit within the receiving end of the pharyngeal breathing tube. The socket may receive a medical fitting. The connection end, the flange, and the socket may form a tubular structure having a first end comprising the connection end and a second end comprising the socket.

Method for detecting leaks and/or verifying adequate closure following a medical procedure, on a hollow or tubular organ of a subject, wherein a leak test is performed by injecting or insufflating, in the concerned organ, a specific test gas which is not commonly produced or naturally present within the body of the subject, or which is present or produced in a precisely known amount or concentration, and by analyzing percutaneously the gas or gas mixture present locally within the body cavity in which the organ is situated, and then verifying the presence, and preferably determining the concentration, of the injected or insufflated test gas in the local gas or gas mixture of the body cavity and indicating whether the concerned organ or a lumen defined by the latter is leak-free or not.

A breathing apparatus includes a control unit configured to control operation of the breathing apparatus based on at least a first input value and a second input value. The breathing apparatus also includes a graphical user interface connected to the control unit. The control unit is configured to display a visual output on the graphical user interface including an area defined by a first axis and a second axis. In addition, the breathing apparatus includes an input unit configured to provide selection of a portion of the area. The control unit is configured to set the first input value in response to the position of the selected portion relative the first axis and to set the second input value in response to the position of the selected portion relative the second axis.

Systems and methods for generating nitric oxide are disclosed. A nitic oxide (NO) generation system includes at least one pair of electrodes configured to generate a product gas containing NO from a flow of a reactant gas; and a controller configured to regulate the amount of nitric oxide in the product gas produced by the at least one pair of electrodes by utilizing duty cycle values of plasma pulses selected from a plurality of discrete duty cycles to produce a target rate of NO production based on an average of discrete production rates associated with each of the plurality of discrete duty cycles.

A therapeutic gas delivery system with at least one gas supply subsystem is disclosed. The at least one gas supply subsystem may include a gas source coupling configured to receive a therapeutic gas source and form a fluid flow connection with the therapeutic gas source, a therapeutic gas delivery system controller, and one or more display(s) configured to be in communication over a communication path with the therapeutic gas delivery system controller. The display may be configured to display a graphical, illustrative, or numerical indicator of one or more flow or system parameters.
