A combination anesthesia circuit holder and patient protection device apparatus configured to be worn on the head of a patient so as to cover at least the eyes and to temporarily secure an anesthesia circuit, the apparatus including a body having at least a perimeter portion and a pad configured at the perimeter portion for being positioned over the eyes of the patient, and at least two strap assemblies formed on the body, a front strap assembly positioned on a front outer surface of the body and a top strap assembly offset vertically from the front strap assembly and positioned on a top outer surface of the body, the strap assemblies cooperating to temporarily secure the anesthesia circuit, whereby placement of the apparatus on the head of the patient provides protection of at least the eyes while safely and effectively securing the anesthesia circuit in a relatively low-profile configuration with relatively minimal interference with a surgical site.

Respiratory devices and methods for their manufacture and use are disclosed. The device features a resiliently deformable element configured to form a perimeter seal with the inner nostril wall and to swab the distal portion of the internal nostril region with a disinfectant during device installation. A first filter stage includes a first filter layer characterized by first geometric convolutions and a first MPPS1 value; and a second filter stage includes a second filter layer characterized by second geometric convolutions and a second MPPS2 value.

A disinfection system is provided. The disinfection system may utilize ultraviolet light and/or ozone for disinfection of infected tissue. For example the system may involve an endoscopic ultraviolet light to disinfect lung tissue. In another aspect, the system may involve a ventilator which provides ozone in small doses to disinfect the tissue. Combinations and variations are further disclosed.

A patient airway dome including an adjustable frame having a hinge such that the hinge allows the frame to adjust between an erected position to create an airway dome and a collapsed position that allows the frame to lay flat, a dome covering located over the retractable frame, a plurality of ultraviolet lights operatively connected to the retractable frame, a plurality of superior glove access portals located on the dome covering, a plurality of inferior glove access portals located on the dome covering, an anesthesia circuit tube operatively connected to the dome covering, and an anesthesia machine connector operatively connected to the anesthesia circuit tube.

The invention relates to a protective cover (1) for a medical ventilator (20) adapted for use in a contaminated environment, in particular an NRBC environment, having a peripheral casing (2) defining an internal compartment (3) designed to accommodate a medical ventilator (20). The peripheral casing (2) has a plurality of connection interfaces (4, 5, 6, 7) sealably attached to said peripheral casing (2). Each connection interface (4, 5, 6, 7) has at least one internal gas passage with at least one gas inlet and at least one gas outlet. A sealing device is arranged in the internal gas passage of at least one connection interface (4, 5, 6, 7) for sealing said internal gas passage.

The invention relates to a ventilator which comprises a pneumatic system for conveying ventilation gas in a flow direction (d) to a patient or from a patient, and further comprises at least one light source which is directed, in emission direction (r), at the ventilation gas and/or at a display area and/or at the pneumatic system.

A portable breathing machine includes a body case (100), wherein: a fan box (101), a cut-off device (108) and a control device (113) are arranged in the body case (100); a fan (8) is arranged in the fan box (101) through a fan noise reduction device (102); an air outlet of the fan box (101) is connected with an internal breathing tube (107); the cut-off device (108) is arranged on the internal breathing tube (107); an air outlet of the cut-off device (108) is connected with an external breathing tube (104) and a mask (105); the fan noise reduction device (102) includes a lower flexible cover (3) and an upper flexible cover (5); the lower and upper flexible covers cooperate to form an enclosed cavity for containing the fan (8). A working noise of the breathing machine is decreased to below 15 decibel.

A breathing assistance apparatus that comprises a housing with inner and outer walls and an upper surface, wherein the walls and upper surface are integrally formed as a single part to avoid seams or joins between the walls to reduce the risk of damage to electronics within the apparatus as a result of liquid leaks. Also disclosed is a control system for a heating element of a humidifier which provides a secondary or back up protection mechanism to disable power to the heating element if a first electronic protection circuit does not cause the first switching member to disable power to the heating element.

An oxygen concentrating apparatus includes an oxygen supply source, an attaching member, and a photodetector. An oxygen discharger is attached to the attaching member while oxygen from the oxygen supply source is supplied to the oxygen discharger. The photodetector is disposed in the oxygen concentrating apparatus and on an extension of an oxygen supply passage of the attaching member.
