A humidifier system for humidifying a microenvironment in a neonatal incubator includes a reservoir configured to hold water to be evaporated for humidifying the microenvironment. A chamber divider defines a heating chamber within the reservoir, and a movable heating element is positioned at a surface level of the water inside the heating chamber so as to heat the water at the surface level inside the heating chamber. The heating element is configured such that it is moved downward within the heating chamber so as to maintain the heating element at the surface level of the water as an amount of water in the reservoir decreases.

Methods and systems are provided for delivering anesthetic agent to a patient. In one embodiment, an anesthetic vaporizer includes a sump configured to hold a liquid anesthetic agent; an ultrasonic transducer coupled to a bottom of the sump and at least partially disposed within the sump; a vaporizing chamber fluidically coupled to the sump; and a heating element coupled to the vaporizing chamber and configured to increase a temperature of a surface disposed within the vaporizing chamber.

A connecting valve structure and an anesthetic filling system are provided. When a valve core assembly is in the open state, a pipe and a filling port are in seal fit, besides, the connecting ring, the seal pipe, and the drug guiding pipe are integrated as a whole, when the seal pipe is inserted into or pulled out of the filling port of the evaporator, no BHT exudate occurs. In addition, an inner pipe wall of the seal pipe, a surface of the connecting ring facing towards a first pipe end, and an outer pipe wall of the drug guiding pipe opposite to the seal pipe together form a pressure stabilizing groove which is used to equilibrate pressure in the container and the evaporator during the open state.

A safety system for a breathing apparatus for delivery of an anesthetic agent having an anesthetic agent vaporizer having a reservoir for containing a liquid anesthetic agent has a reservoir for containing a liquid medical agent, a port for filling the reservoir with the liquid anesthetic agent, and a sensor device for sensing a filling action of the port. A change of position of a lid covering the port is can be detected, or insertion of a fill vessel into said the port is can be detected. Thus safety of said the equipment is improved by being able to de-pressurize the reservoir before opening a filling valve for communication of the port with the interior of the reservoir.

Systems and methods are provided for a valve shut-off system of a medical device. In one embodiment, the valve shut-off system of the medical device includes a first pin movable between a first position where a valve is opened and a second position where the valve is closed, the first pin including a slot, and a second pin having a mating geometry with the slot of the first pin, the second pin adjustable between a locked position that holds the first pin in the first position and an unlocked position that enables movement of the first pin between the first position and the second position.

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.

The present invention provides a new inhaler device for the administration of inhalable liquids to a patient offering one or more advantages or improvements over known inhalers, particularly inhalers for the delivery of halogenated volatile liquids such as methoxyflurane for use as an analgesic.

Liquid accumulators and methods for reducing pulsations of a liquid flow are disclosed. A liquid delivery system comprises a pump configured to drive liquid to a pipe. The pipe is configured to transmit a liquid flow. A liquid accumulator is fluidically connected to the pipe. The liquid accumulator comprises a chamber containing the liquid and a vapor column and a power source configured to input energy to the chamber to generate vapor from the liquid to form the vapor column. The vapor column constitutes a gas spring to reduce pulsations of the liquid flow in the pipe. The spring rate of the gas spring can be adjusted by changing the input energy level from the power source to the chamber.

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.

A pharmaceutical product includes an inhalation anesthetic stored within an aluminum container. According to such a product, the interior of the aluminum container is provided with an inert lining comprising an epoxyphenolic resin, and the inhalation anesthetic is selected from the group consisting of sevoflurane, desflurane, isoflurane, enflurane, methoxyflurane and halothane.
