Systems and methods are provided for detecting unacceptable accelerations by an anesthetic vaporizer, such as due to drops and mishandling. In one embodiment, a method for an anesthetic vaporizer comprises determining a quantitative acceleration of the anesthetic vaporizer based on acceleration vectors measured by an accelerometer coupled within the anesthetic vaporizer, and outputting an alert responsive to the quantitative acceleration exceeding an acceleration threshold. In this way, drop-related degradation may be identified in a timely fashion.

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.

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.

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.

Various examples disclosed relate to an apparatus and method for use in verifying input gas, such as differences between a first and a second gas in an anesthesia flow control where one of the gases is oxygen gas and the other of the gases is nitrous oxide gas. The apparatus can include, for example, a chamber having an inlet to receive gas and a vent to exhaust the gas, a gas control to fill the chamber with the gases to a determined begin pressure, and a microprocessor configured to measure respective times to exhaust the first gas and the second gas from the chamber, via the vent, to reach a determined end pressure. Based on time to exhaust the respective gases, a difference between the first and second gases can be identified; this verification can verify that improper crossover/ross-connection of gas supply lines is not present.

This disclosure includes a method for treating a patient suffering from alcohol withdrawal. The method comprises administering an effective amount of oxygen to the patient and administering an effective amount of nitrous oxide to the patient. In some embodiments, the effective amount of oxygen and the effective amount of nitrous oxide are administered to the patient via a nitrous oxide sedation system.

A signaling apparatus for an anesthesia machine, the signaling apparatus comprising an user input sub-module for receiving input information from an user, an available gas sub-module for signaling types of currently available gases according to information of the user input sub-module, and an available gas outlet sub-module for signaling currently available gas outlets according to information of the user input sub-module.

A coated anesthetic container for an anesthetic dispenser includes an anesthetic tank, which is capable of receiving a liquid anesthetic (Nm), as well as a refill unit for refilling liquid anesthetic (Nm). The anesthetic tank includes a wall and a coating on the inner surface of the wall. A wall of the refill unit is connected in a fluid-tight manner to the wall of the anesthetic tank. A coating is applied at least to the inner surface of the wall of the anesthetic tank. This coating is made of an alloy of nickel and phosphorus. The nickel portion is in a range of 80 wt.% to 97 wt.%, and the phosphorus portion is in a range of 3 wt.% to 15 wt.%. A process is provided for manufacturing such an anesthetic container.

An arrangement and a process filter out at least one gas from a gas mixture. A filter unit (4) of the filter arrangement comprises an inlet and an outlet and is adapted to filter the gas out of the gas mixture while the gas mixture flows through the filter unit (4). The filter unit (4) takes up the gas and heats up in the process. A filter temperature sensor (46, 46.2) of the filter arrangement is adapted to measure at least once an indicator of the temperature in a first measuring area (MP, MP.2) inside the filter unit (4). Depending on the measured temperature, a message is generated and output in a form perceptible by a human being. This message includes information about the current state of the filter unit (4).

Disclosed is a respirator which comprises an electronic control device and a pneumatic main line in which the following are connected pneumatically: a respiratory gas source, a valve, a mixing chamber, a gas-dosing unit, and a supply line. The gas-dosing unit is configured to convey external air and/or oxygen and/or anesthetic gas into the mixing chamber, the respiratory gas source is configured to deliver respiratory gas to the supply line, the mixing chamber is configured to make available respiratory gas, the supply line is configured to supply the patient with respiratory gas, and the valve is configured to at least temporarily reduce a stream of respiratory gas to a patient.
