The present disclosure relates to medical devices, namely to devices for inhalation of volatile anesthetics. An inhalation device, a syringe filled with a volatile anesthetic, as well as an inhalation system comprising an inhalation device and a syringe filled with a volatile anesthetic are provided. The technical contribution of the present disclosure resides in that that the inhalation device and the inhalation system prevent the volatile anesthetic vapor from entering the environment; enable the inhaler to adjust the doses of the volatile anesthetic fed to the inhalation device; expand the range of means for the inhalation with the volatile anesthetics, in particular, means for the inhalation with methoxyflurane.

A vaporizer for delivery of a volatile medium to a gas flow, the vaporizer comprising: a gas delivery unit (3) which receives a flow of gas and provides a flow of gas containing a metered amount of a vaporized medium; a reservoir unit (5) which contains a volatile medium and maintains a supply of the vaporized medium, wherein the reservoir unit is selectively fluidly connected to the gas delivery unit; a gas sensing unit (7) for sensing a flow rate and/or composition of the gas flow; a vaporized medium sensing unit (9) for sensing a flow rate of the vaporized medium; a manifold (10) which includes flow paths for the vaporized medium and fluidly connects the reservoir unit and the vaporized medium sensing unit; and a control unit (11) for controlling a flow rate of the gas flow and an amount of the vaporized medium which is metered into the gas flow.

Atomizer for a ventilation machine with a ventilator, including a body with a first connection for connecting the atomizer to a ventilator and a second connection for connecting the atomizer to a line leading to a patient, wherein the body forms a flow channel from the first connection to the second connection; and an atomizing device for atomizing a fluid; wherein the atomizing device is disposed between the first connection and the second connection in the flow channel and adapted so that the fluid can be atomized substantially parallel to, and preferably in, the flow direction from the first connection to the second connection.

A respiration moistener (1) has an inlet (3), into which incoming gas (2) to be moistened can be fed. Vapor (21) is mixed with the incoming gas (2) in a mixing chamber (4). Moistened outgoing gas (5) flows out of an outlet (6). In cases in which the temperature of the incoming gas (2) becomes so high that the temperature of the outgoing gas (5) is above a desired value, the internal desired value is adjusted. The outgoing gas (5) can then cool to the desired value on its way through the inspiration tube (7).

An apparatus and system for transferring a liquid, such as an anesthetic, from the outlet port of a reservoir to a machine while effectively and conveniently minimizing the release of anesthetic. In one embodiment, the apparatus and system can include a first valve movable between a first position and a second position; a first housing surrounding the first valve; a second valve slidably connected to the first valve and movable between a third position and a fourth position; and a second housing which surrounds the second valve; wherein the apparatus defines a first opening, a second opening, and a receiver passage between the first and second openings. In another embodiment, a movable plunger can be slidably connected to the second valve.

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.

The present application discloses a sealing valve and an anesthetic bottle. The sealing valve includes a valve body and a valve core. The valve body is provided with a first end, a second end and a channel. The end surface of the first end and/or the inner wall surface of the channel are provided with a first right angle portion and a second right angle portion, the valve core is arranged in the channel, and the outer wall surface of the valve core is convexly arranged with an engagement ring. The engagement ring is provided with a conical surface and an annular groove. The conical surface can abut against the first right angle portion and the second right angle portion to close the channel, or separate from the first right angle portion and the second right angle portion to open the channel.

The present application discloses a sealing valve (10), including a guiding tube (1), comprising a first end (11) configured to be inserted into an outer packaging bottle and a second end configured to be connected to an anesthesia vaporizer (12); the outer peripheral surface of the first end (11) is provided with a convex ring (111) protruding toward the inner wall of the outer packaging bottle and abutting against the inner wall of the outer packaging bottle; and a pushing rod (2) configured to be arranged in the guiding tube (1) and slidable along an axial direction of the guiding tube (1) to connect the anesthesia vaporizer with the outer packaging bottle or to block between the anesthesia vaporizer and the outer packaging bottle.
