Systems and methods for medical patient distraction may permit watching an immersive video headset during a dental or medical procedure that is compatible with nitrous oxide. Having the ability to watch a show on an immersive video headset while using nitrous oxide may allow for further distraction of the patient from the discomfort of dental or medical procedures. The parts and pieces of the immersive video headset that touch the patient may be detachable so they can be changed between patients for easy sterilization and cleanliness. Also, the immersive video headset may be capable of mirroring what is on a phone or nearby computer. The design of the headset may be specifically compatible with being able to use a nitrous hood during dental or medical procedures.

The disclosure relates to a method and respiratory system, comprising: a flow generator to provide a gas-flow to a patient, the gas flow comprising an oxygen fraction, and a controller configured to: receive input relating to oxygen fraction at a patient's nose and/or mouth, adjust the gas-flow flow rate based on the oxygen fraction at the patient's nose and/or mouth.

Disclosed herein is a method and apparatus for determining a parameter of a gas present in an exhaled gas flow comprising: providing an apparatus gas flow with a time-varying parameter to a patient, measuring a parameter of the gas present in a composite gas outflow from the patient, and determining the parameter of the gas present in the exhaled gas flow using the measured parameter of the gas present in the composite gas outflow and the time-varying parameter.

Systems and methods are provided herein for remotely controlling a life-critical medical device. In one example, a system includes a life-critical medical device communicatively coupled to a remote device and configured to supply a medical therapy to a patient, the life-critical medical device including a display and memory storing instructions executable to output, to the display, a graphical user interface (GUI) that displays a plurality of real-time machine settings of the life-critical medical device, responsive to a first user input, display, via the GUI, a remote control panel including a session code usable to authenticate the remote device, and responsive to receiving an indication from an access server that the remote device has been authenticated, display, on the GUI, a notification indicating that the life-critical medical device is currently controlled by the remote device.

The disclosure provides an anesthesia machine, a veterinary anesthesia machine, and a waste gas absorption tank supporting device, the waste gas absorption tank supporting device including: a tray provided with a tray recess; and a protrusion structure provided on the tray, the protrusion structure being capable of forming a circumferential protective structure located on an outer side of the tray recess and configured to protect a waste gas absorption tank, and an inner side surface and an outer side surface of the protrusion structure being both protective surfaces capable of protecting the waste gas absorption tank. The waste gas absorption tank supporting device provided by the disclosure can effectively support waste gas absorption tanks of various sizes, so that the waste gas absorption tank is prevented from sliding off from the waste gas absorption tank supporting device during the movement of the anesthesia machine.

This disclosure provides a perfusion device, an anesthetic vaporizer, and an anesthetic machine. The anesthetic vaporizer includes a vaporizer body and the perfusion device. A feed port and a tank are provided in the vaporizer body. The perfusion device includes a mounting assembly, an ejector rod assembly, and a valve core assembly that is provided with a liquid inlet channel. The mounting assembly includes a mounting seat that is mounted on the feed port and provided with a hollow structure having an opening at both ends. The valve core assembly is movably mounted on one opening of the hollow structure, and the ejector rod assembly is movably mounted on the other opening of the hollow structure and forms a sealed structure with the mounting assembly. The ejector rod assembly may drive the valve core assembly to move toward the tank, and the liquid inlet channel communicates with the hollow structure.

A calibration method for an oxygen sensor and a medical ventilation system are disclosed. At least two electrical signals are acquired at two time points within a preset time period, when the oxygen sensor is in a preset oxygen concentration. A response function of the oxygen sensor which corresponds to the preset oxygen concentration, is determined according to the at least two time points and the at least two electrical signals. A steady-state output value of the oxygen sensor in the preset oxygen concentration is determined, according to the response function and a characteristic curve of the oxygen sensor is determined, according to the steady-state output value of the oxygen sensor in the preset oxygen concentration. The described method reduces the time waiting for the oxygen sensor to respond, thus improving calibration efficiency, and facilitating the improvement of the oxygen concentration monitoring accuracy of a ventilation device in daily use.
