A system includes a pressure regulator including a housing, an inlet for connection to a pressurized gas comprising oxygen, and at least one energy transfer element. The system further includes a respiration facepiece including at least one seal system to form a sealing engagement with the face of a user to encompass the nose and mouth of the user, thereby creating a volume of sealing engagement between the respiration facepiece and the user, an opening into the volume of sealing engagement of the respiration facepiece in communicative connection with an interface for removable attachment of the pressure regulator to the respiration facepiece, and an inspiration port in fluid connection with the interface and in fluid connection with the volume of sealing engagement. The pressure regulator interface includes at least one cooperating energy transfer element such that energy can be transferred between the at least one energy transfer element and the at least one cooperating energy transfer element to transfer at least one of data or power into the volume of sealing engagement.

Data communication and displays for breathing apparatus facepieces and pressure regulators

A respiration system includes a pressure regulator including a housing, an inlet for connection to a pressurized gas comprising oxygen, and a first data communication system, and a respiration facepiece including an interface to which the pressure regulator is removably attachable, at least one seal system to form a sealing engagement with the face of a user to encompass the nose and mouth of a wearer; an inspiration port in fluid connection with the pressure regulator interface and in fluid connection with the interior of the facepiece and at least one display within a volume of sealing engagement with the face of the user that is within the field of view of the user. The pressure regulator interface includes a second data communication system to receive data from the first data communication system to control the at least one display. A sealing attachment may, for example, be formed between the pressure regulator and the interface of the facepiece.

A respiration system includes a regulator including an inlet for connection to a source of pressurized gas and an outlet for delivery of the gas to the user, and a respiration facepiece for use in connection with the regulator including an interface removably attachable to the regulator, at least one seal system adapted to form a sealing engagement with the face of a user, an inhalation port in fluid connection with the regulator interface and with the facepiece interior, an inhalation check valve in fluid connection between the inhalation port and the facepiece interior; an exhalation port in fluid connection with the facepiece; an exhalation check valve in fluid connection with the exhalation port; and an ambient port separate from the inhalation port and from the exhalation port, which is in fluid connection with the facepiece interior without an intervening check valve.

Facepiece with open port

A respiratory half-mask, including a mask body having a front or side filters, and exhalation valves, a head support with two side straps emanating from support, and a strap guide part fastened on the mask body for sliding the mask body along the side straps from a usage position for covering a mouth and a nose of the user into a position for exposing the face of the user. At least one clamping element is adjustably attached to the strap guide part for clamping the side straps to the strap guide part and for fixing the mask body on the two side straps in a usage position.

Respiratory half-mask

In a respirator mask in which the visor panels can be covered by light-absorbing supplementary panels, first and second snap-in hooks are molded onto opposite sides of the visor panel and a stop is molded onto a corner section to form a guide pocket. The outer contour lines and the convexity of the visor panel and the supplementary panel are identical. To attach the flexurally elastic supplementary panel, it is first fastened in the guide pocket and on the first snap-in hook. Then the opposite side is locked into the second snap-in hook after flexing the supplementary panel.

The invention relates to a head harness for a respirator which comprises a head plate ( ) that is elastic in the X direction and that is substantially nonelastic in the Y direction. Front straps ( ), temple straps ( ) and neck straps ( ) are fastened to the head plate, only the temple and the neck straps being extensible. The strap buckles ( ) provided for fastening the front and temple straps to the mask base are rigidly adjusted according to the head size so that the mask is already correctly positioned and preliminarily fixed when put on and only the neck strap has to be readjusted. The head harness can be adapted to different head shapes and sizes and allows for a high wearing comfort. The respirator can be quickly and easily put on.

Feeding apparatus for breathing masks that allows food and drink intake when the mask is in use

A feeding valve having a hose coupling in the form of an expansion bellows which unfolds automatically into the wearer's field of vision when the sealing cap of the feeding valve is opened, thereby enables a wearer to easily insert the straw of a food or beverage bottle even when wearing protective gloves.

This invention relates to a replaceable eye-protecting lens system for breathing masks that is easy to handle and ensures a firm and safe, i.e. gas-tight fit of the lenses in the body of the mask. It is the object and problem of this invention to create a replaceable eye-protecting lens system that provides a wide field of vision for the person wearing the mask and ensures a mechanically firm and gas-tight fit of mask body and lens. This problem is solved according to the invention by creating a replaceable lens system for breathing masks wherein a groove-shaped holding fixture is placed on the rim of eye-protecting lens which holds a fastening element of the mask body and a locking ring
