A face engaging device such as a nozzle, facemask, etc., may include a housing including a fluid channel extending through the housing to an opening configured to be placed in fluid communication with the mouth of a user. The housing may include a first surface configured to be placed in contact with the skin of the user and a second surface exposed to the fluid channel. The face engaging device may also include a thermal actuator supported by the housing and including a first heat transfer surface position on the first surface, where the first heat transfer surface is configured to apply a thermal profile to the skin of the user when the opening is placed in fluid communication with the mouth of the user.

A method for automatically detecting a clinically relevant leak and/or inadequate closure following a medical procedure, in a hollow organ residing in the interior volume of a body cavity. The test method includes the steps of: injecting, via an adapted injection element, a specific test gas or a gas mixture containing at least one test gas, into the organ, analyzing the gas mixture and measuring the test gas concentration in the interior volume of the body cavity via an adapted detection element and at least during a measurement window, evaluating the likelihood of the presence of a leak and its degree of severity, by comparing stored data and real-time data with each other. The pressure difference between the interior of the hollow organ(s) and the interior volume of the body cavity is controlled or mastered at least at a given moment during at least one measurement window.

A device is described for delivering a therapeutic vibration to a body. The device may include at least two motors in a housing with unbalanced masses coupled to their axles, such that vibration of the masses causes the two motors and housing to vibrate at a beat frequency 80. The motors and housing may be coupled to the body via a platform which places the motors and housings at or near a resonant structure in the body, creating a coupled oscillation between the platform and the body. The vibration may be based on the input signal, such that the system applies the vibration based on the input signal to the user, wherein the signal may be an audio or video signal. The system may be configured to measure and manipulate the flow of cerebral spinal fluid.

An anesthetic dispenser (100) includes an anesthetic tank (7) and a mixing unit (9) that mixes an anesthetic from the anesthetic tank with a carrier gas. Liquid anesthetic (Nm) can be refilled into the anesthetic tank through a refill opening (6). In one operating mode, a specified operating pressure is maintained. A closure (16) is moveable from a closed position via an intermediate position to an open position and closes the refill opening in both the closed position and the intermediate position. When the closure is moved from the closed position to the intermediate position, a transition time period elapses. A position sensor (22) detects the event that the closure has been moved out of the closed position. In response to this detection, pressure in the anesthetic tank is lowered during the transition period to a refill pressure that is still above ambient pressure. The closure is then opened.

A system includes a charger and a cracker. An antiviral may be delivered through the charger. The cracker may include a first section and a second section to control the flow of the antiviral from the charger. The first section may receive the charger. The first section and the second section may be coupled together by using screw threads on the first and second sections. The cracker is configured to regulate the flow of antiviral into the user. The antiviral within the charger may include oxygen (O2) and nitrous oxide (N2O). Specifically, the antiviral may a mixture including 75% N2O and 25% O2 that inactivates the DNA and/or RNA of viruses, viroids, and germs.

A method of determining a duration of safe apnoea. Information is obtained relating to a respiratory indicator, which can include information relating to a potential respiratory equilibrium, and a duration of safe apnoea is determined from the obtained information.

An apparatus (1) for supplying a gas mixture to a patient, having a gas inlet line (30) with a gas inlet orifice (30a) that splits into a first gas line (31) and a second gas line (32); at least one permeation module (33) arranged on the second gas line (32), the said permeation module (33) having a feed port (33a) in fluidic communication with the second gas line (32), a retentate port (33b) and a permeate port (33c); a third gas line (34) in fluidic communication with the retentate port (33b) of the permeation module (33); a fourth gas line (35) in fluidic communication with the permeate port (33c) of the permeation module (33), and coupling fluidically to the said first gas line (31); and a source (360) of air in fluidic communication with the first gas line (31) and the fourth gas line (35).

An anesthetic gas delivery system includes a gas machine for supplying anesthetic gas to a patient; a scavenging control system that controls a level of vacuum suction to evacuate waste anesthetic gas; and a user interface electronically coupled to the scavenging control system. The scavenging control system includes an air flow sensor external from the gas machine that measures the flow rate of the waste anesthetic gas through the scavenging control system; a control valve, such as a proportional solenoid valve, that is controllable to adjust the level of vacuum suction to adjust the flow rate of the waste anesthetic gas; and electronic control circuitry that is configured to receive a measured flow rate from the sensor and to control the control valve to adjust the level of vacuum suction based on the flow rate measured by the sensor. The electronic control circuitry further is configured to transmit flow rate information corresponding to the flow rate measured by the sensor to the user interface.
