The adapter (89) comprises an instrument accommodating housing (15) through which an instrument bore (25) extends therethrough. The instrument accommodating housing (15) terminates at one end in a first main port (20) engageable with an instrument port (7) of the face mask (90), and in the other end in a second main port (23). The instrument shielding device (92) comprises a shielding sleeve (95) a first end (96) of which is secured by a coupling ring (98) to the second main port (23) of the adapter (89), and a second end (97) of which is secured in a storage chamber (94) of a sleeve storing housing (93) of the instrument shielding device (92). The sleeve storing housing (93) is sealably engageable with a proximal end (58) of an endoscope (10), and the shielding sleeve extends from a collapsed stored state in the storage chamber (94) to the adapter (89) for shielding the endoscope (10).

A system for sterilization of a medical device comprising at least one medical device and at least one sterilization device. The sterilization device comprises at least one plasma generator and at least one water source and/or water vapor source for providing water and/or water vapor. The sterilization device is configured to generate plasma-activated water vapor and the system is configured to at least partially conduct the plasma-activated water vapor through the medical device.

A system and process for the recovery of at least one halogenated hydrocarbon from a gas stream. The recovery includes adsorption by exposing the gas stream to an adsorbent with a lattice structure having pore diameters with an average pore opening of between about 5 and about 50 angstroms. The adsorbent is then regenerated by exposing the adsorbent to a purge gas under conditions which efficiently desorb the at least one adsorbed halogenated hydrocarbon from the adsorbent. The at least one halogenated hydrocarbon (and impurities or reaction products) can be condensed from the purge gas and subjected to fractional distillation to provide a recovered halogenated hydrocarbon.

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.

Introduced here is a self-contained face mask system with an automated liquid-droplet dispensing mechanism (ADM) for humidification. The enclosure of the self-contained mask system can be comprised of one or more layers of breathable fabric adapted to flexibly conform to the face of a user when worn to form a cavity that is adjacent the nostrils and mouth. The ADM of the face mask system can be comprised of a reservoir in which liquid is stored, a respiratory cycle detector, a timer and controller, and a droplet dispenser that controllably dispenses droplets of the liquid from the reservoir into the cavity for inhalation by the user. The ADM can be contained entirely within the face mask enclosure or supported on the surface of the face mask enclosure such that the self-contained mask system, when worn by a user, can be supported entirely by the head and neck of the user.

The present disclosure provides systems and method for electric plasma synthesis of nitric oxide. In particular, the present disclosure provides a nitric oxide (NO) generation system configured to produce a controllable output of therapeutic NO gas at the point of care.

Methods of capturing respiratory droplets are provided which use coatings comprising a polyelectrolyte polymer and a viscosity modifier. In embodiments, a method of capturing respiratory droplets comprises absorbing respiratory droplets on a surface of a coating, the coating comprising a polyelectrolyte polymer and a viscosity modifier, wherein absorbed droplets leave depressions in the surface of the coating. Coated substrates and coating compositions used to form the coated substrates are also encompassed.

A biocontainment assembly for use with a patient suspected of having or diagnosed with a transmissible disease(s) capable of respiratory, airborne, contact, or droplet transmission includes a housing configured to be positioned over and at least partially enclose a head, neck, and/or torso of the patient. A sidewall of the housing includes an open portion contiguous with an at least partially pen bottom portion of the housing, sized to fit over at least a portion of the head, neck, and/or a torso of the patient. The housing also includes an airflow opening for evacuating fluid from an interior defined by the housing. The assembly also includes a drape configured to extend across the open portion of the sidewall having a first portion removably connected to the housing and an opposing second portion configured to be draped over the torso, abdomen, waist, and/or legs of the patient.

A nebulizer device aerosolizes (or vaporizes) liquid drawn from a liquid reservoir via a fluid flow path into a nebulization chamber. An inlet port is coupled to an external air supply and leads through a check valve and Venturi nozzle (e.g. a duckbill valve) into the chamber to direct an air stream across an opening of the fluid flow path. A discharge port leads from the chamber to a user mask, mouthpiece or canula, where the aerosol or vapor mixture can be inhaled. A filtered outlet port isolates exhaled material from the external environment. Multiple discrete heating elements may be placed around the fluid flow path to preheat the liquid. If the liquid is sufficiently volatile, heating may vaporize the material which can condense back into an aerosol after mixing with the air stream. A set of check valves direct one-way fluid flow and prevent leakage or spillage of material from the device.

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.
