A face mask (90) comprises an instrument shielding apparatus (91) which comprises an instrument shielding device (92) which is connected to the face mask (90) by an adapter (89). 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).

Systems and methods producing a customised patient respiratory interface are disclosed. Data representative of one or more landmark features of a head of a human is obtained. One or more landmark feature locations of the landmark features are identified based on the data. A set of manufacturing specifications for production of the patient respiratory interface component is determined based on the one or more landmark feature locations. The patient respiratory interface component is produced based on the set of manufacturing specifications.

An apparatus for delivery of a flow of gases to a user, such as a respiratory therapy apparatus, is provided. The apparatus may have first and second inlets for receiving supplementary gases flows, a blower to generate the gases flow to the user, and a controller. A valve and a sensor may be provided in the second inlet. The controller may be configured to detect the disconnection of a gases source from the second inlet, and to respond by operating the valve and/or triggering an alarm. The controller may be configured to determine whether a gases flow is being provided at one or both of the inlets, and to accordingly control an operational mode of the apparatus.

A breathing apparatus may include a heater configured to kill harmful organisms in air. The apparatus may include a vest, including a heating chamber disposed on the vest and a cooling chamber disposed on the vest. The heating chamber may include a heat source, and the heat source may heat air disposed within the heating chamber to a predetermined temperature. The heating chamber and the cooling chamber may be in fluid communication. The apparatus may include a breathing tube, including a first end and a second end. The first end may connect to the cooling chamber. The apparatus may include a breathing mask. The second end of the breathing tube may connect to the breathing mask. The cooling chamber and the breathing mask may be in fluid communication via the breathing tube.

A closed loop filtration system includes first and second trocars providing sealed access to a body cavity, a power supply, first and second ionizer units electrically coupled to the power supply, and a filter cartridge. The filter cartridge includes an inlet in communication with the first trocar, an outlet in communication with the second trocar, a first electrode disposed downstream of the inlet of the filter cartridge, and a second electrode disposed downstream of the first electrode. The first electrode is electrically coupled to the first ionizer unit to ionize airborne particulate matter flowing therethrough. The second electrode is electrically coupled to the second ionizer unit and configured to attract the airborne particulate matter that is ionized by the first electrode.

A heat and moisture exchanger device comprising a housing containing a microcurrent-generating filter capable of generating a low level microcurrent. A microcurrent-generating filter can reduce the number of living or active microbes.

A bite block includes a main body and a mouthpiece extending outward from the main body and configured to be positioned in a mouth of the subject when the bite block is in use. The mouthpiece can include a main channel configured to receive an endoscopic tube and a sampling channel configured to receive orally exhaled gases from the subject. The bite block can include a gas delivery channel configured to direct gases into the subject's mouth, the gas delivery channel extending through a portion of the main body and through a portion of the main channel such that the gas delivery channel is in fluid communication with the main channel. The bite block can include a recess extending along a portion of the first surface of the main body proximate the gas delivery channel and configured to receive a portion of a gas delivery tube.

A medical fluid treatment system includes a source of purified water; at least one concentrate for mixing with the water from the source to form a treatment fluid; a disposable set including a pumping portion, a concentrate line in fluid communication with the concentrate source and the pumping portion, and a patient line in fluid communication with the pumping portion, the patient line including a filter having a membrane configured to filter the treatment fluid, the filter configured such that (i) fresh treatment fluid flowing from the pumping portion towards a patient flows through the membrane and (ii) used treatment fluid flowing through the filter from the patient to the pumping portion bypasses the membrane; and a medical fluid delivery machine including a pump actuator operable with the pumping portion of the disposable set.
