A supply arrangement (100) and a process supply a medical device (50, 90) with a supply gas mixture. The supply gas mixture includes a carrier gas and an anesthetic and is generated by an anesthetic dispenser (3). A carrier gas mixing unit (9) generates the carrier gas from at least two carrier gas components. A carrier gas switch having a regular outlet and a discharge outlet selectively directs carrier gas components to the carrier gas mixing unit or to a discharge line (35). A gas mixture switch (6), having a regular outlet (41) and a discharge outlet (42) selectively directs the supply gas mixture to the medical device or to the discharge line (35). An anesthetic concentration sensor (5.1, 5.2) measures a concentration of anesthetic in the generated gas mixture. A control unit (2) controls the gas mixture switch based on measured concentration within or outside a predefined range.

Examples of a module for housing unrelated electronic and electromechanical equipment for use during surgery. The module can include a lower section and a tower-like upper section. The lower section can house unrelated electronic and electromechanical equipment. The tower-like upper section can be located on top of the lower section. A water-resistant cowling can enclose at least a portion of the lower section and the tower-like upper section. A cartridge containing one or more ultraviolet-C producing lights can be protectively housed within the tower-like upper section. The cartridge containing one or more ultraviolet-C producing lights can be configured to emerge upward from a top of the tower-like upper section to substantially seat itself on the top of the tower-like upper section when activated allowing the ultraviolet-C light to disinfect the patient and staff-contacting upper surfaces of the equipment in the operating room.

An anesthetization gas mask for a small animal includes a first mask part providing an inlet for an anesthetization gas and a second mask part for transmitting the anesthetization gas. The first and the second mask part define an anesthetization volume for receiving an animal’s mouth part. The second mask part transmitting the anesthetization gas is movably connected to the first mask part having the inlet for an anesthetization gas. The anesthetization gas mask is geometrically constructed such that a movement of the first mask part from a working position to a blocking position relative to the second mask part blocks the passage of anesthetization gas into the anesthetization volume. This anesthetization gas mask has a valve function integrated in the mask system itself, so that anesthesia gas is not spilled when not in use and with a fixed geometry so that the extraction is always present when handled.

A neck strap, a crown strap assembly and a headgear for a breathing mask. The neck strap for a headgear includes a one-piece main body adapted to engage a patient's neck, first and second lower connection portions adapted to connect to first and second lower mask connection straps, and first and second upper connection portions adapted to connect to respective first and second lateral crown straps.

A sedation device has a housing divided internally into a ventilator chamber and an associated evaporator chamber which overlap and are separated by a filter mounted between the chambers and forming a common gas-permeable dividing wall between the chambers. An inlet port is provided at one end of the ventilator chamber at a top of the housing for connection to a patient ventilator in use. An outlet port on the evaporator chamber can be connected via a breathing tube to a patient. An evaporator is mounted within the evaporator chamber for delivery of a volatile sedative into the evaporator chamber during use.

Provided herein is a capnography fitting for use in a capnography system wherein the capnography fitting is configured to fit inhalation masks of various sizes and shapes so that viable carbon dioxide readings can be obtained from an air sample obtained from a patient's exhaled gas. The fitting includes a rigid tube having a proximal end inlet configured to receive an inhalation gas and to slidably engage a mixed gas fitting, and a distal end outlet configured to slidably engage directly to an inlet of an inhalation mask configured to cover a nose and/or mouth. The tube also includes an angled port in fluid communication with and disposed adjacent to the proximal end inlet or the distal end outlet. Methods and kits are also provided.

A hood for a sterilization system including a return line (132) to provide for airflow between first and second ends; a hood (116) having an opening situated in a top wall and configured to be coupled to a tube; and couplers (126) configured to couple the hood to adjacent ones of a plurality of support struts (114) to configure the hood to form an opening (128) leading to a cavity (129), wherein the cavity is configured to receive at least a portion of a head of a subject (101) receiving respiratory gas from a ventilator (170) such that the plurality of support struts are situated outside of the cavity, wherein the hood is configured to enable ambient air into the airflow while over the portion of the head of the subject.

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 protective apparatus for use in medical and dental procedures to prevent exposure and exchange of harmful substances between an area isolated by the apparatus and the environment of use. The apparatus includes a physical shield, a vacuum barrier, and an adjustable support frame. The apparatus further includes a vacuum connector for connecting the apparatus to a vacuum source, a vacuum conduit for flow communicating with the air around the perimeter of the physical shield such that the vacuum source draws air along with solid and liquid matter entrained in the air into the vacuum conduit, and a plurality of vacuum apertures located along the vacuum conduit for communicating the vacuum source with the air. The apparatus provides protection for persons in proximity to a source of harmful substances such as aerosols derived from patients infected with viruses or the like and more in particular corona viruses.

A passive oxygen mask and vacuum regulation system disposed in fluid communication with a vacuum scavenging array includes a passive oxygen mask dimensioned to fit over a patient's nose and mouth and having a gas inlet port and an expired gas outlet port. A vacuum regulation assembly has a vacuum regulator which includes an expired gas discharge tube disposed in fluid communication between the passive oxygen mask and the vacuum regulation assembly, and a vacuum suction tube disposed in fluid communication between the vacuum regulation assembly and the vacuum scavenging array. The vacuum regulation assembly further comprising a vacuum attenuation port through a portion of a regulator housing, wherein the vacuum attenuation port is at least partially defined by an attenuation port diameter dimensioned to reduce a vacuum suction pressure in the expired gas discharge tube to a predetermined vacuum suction pressure.
