The breathing humidifier is a reservoir containing a sponge and water. The reservoir is generally shaped to fit the contour of the users face between the upper lip and the nose. The sponge is shaped to fit against the nostril openings. Two openings are located at the bottom of the reservoir into which a gas supply cannula may be inserted. When gas such as oxygen is supplied to the breathing humidifier the gas passes through the water-sponge and heat environment to exit into the nose.

A breathing film comprising at least one layer obtained by processing a propylene resin composition including crystalline propylene polymer(A) and propylene/.alpha.-olefin random copolymer(B) is provided, said film having anti-bacterial agent, and the ratio [.eta.].sub.B /[.eta.].sub.A of intrinsic viscosity [.eta.].sub.B of propylene/.alpha.-olefin random copolymer(B) and intrinsic viscosity [.eta.].sub.A of crystalline propylene polymer(A) being 0.3 to 1.2, and said film having specified range...

A breathing apparatus includes a regulator which delivers air to a user wearing a mask. The regulator is connected to the mask through an adaptor. The adaptor includes an exhalation valve which enables the user's breath to pass out of the adaptor to atmosphere. The regulator includes a sensing diaphragm that is movable responsive to pressure in the mask. A main valve delivers air to the mask responsive to opening of a pilot valve. The pilot valve includes a pilot opening. A lever moves in respon...

A breathing apparatus comprises at least one spherical container (15) for breathable gas attached to a harness (1,9,20,21) (5) (109) for securing the same to a user. Each container may be located within a protective casing (14,14') and is preferably formed of composite material.

A breathing apparatus adapted for use in combination with a tube for swimming, the breathing apparatus includes a floatable body having a hollow case for floating over water level and an opening; and a breathing assembly mounted detachably. The breathing assembly has a connector inserted within the opening of the floatable body; a fixing cap mounted on the floatable body for preventing separation of the breathing assembly from the floatable body, and for providing fresh air from the outside to t...

In breathing apparatus, inhalation valve means, which allows gas to be inhaled from an inhalation conduit, is situated directly within the path of flow of the exhaled gas so that, in operation, heat is transferred from the exhaled gas to the inhalation valve means. The flow of warm, exhaled gas over the inhalation valve means raises the temperature of the valve means and reduces the likelihood of ice formation.

A breathing apparatus having a breathing mask which consists of an outer mask provided with eye pieces and an inner mask enclosing the mouth and the nose. A gas chamber is connected with the mask and is divided into two rooms. A first room comprises an inlet valve and is in direct gas fluid communication with the space between the outer and the inner mask, and a second room comprises an outlet valve and a membrance for controlling the inlet valve and is in direct gas fluid communication with the...

There is disclosed a breathing circuit which includes a swivelled fitting for connection to a patient's face mask or endotracheal tube and for connecting thereto breathing hoses which are to be connected to an anesthetic machine or to a pulmonary ventilator. The fitting is characterized in that the hoses are laterally disposed with respect to the patient's nose. The circuit in its entirety is further characterized in that it is light in weight, is translucent and is designed for one-patient use ...

A single strip of flexible and impervious material is folded lengthwise upon itself to form a double-thickness member, which is provided midway between its ends with a recess extending inwardly from one edge. The edges of the strip and substantially all of the area between the recess and the other edge of said member are sealed together so that two longitudinally spaced breathing bags are formed that are integrally connected at their inner ends by a band adapted to extend around the back of the ...

A breathing valve having a housing comprising an inlet chamber in communication with which is an inlet opening controlled by an inlet valve, a passage to the breathing organs of the user and an exhalation valve. A control diaphragm subject on one side to the pressure in the inlet chamber acts through an intermediate member to control the inlet valve. An overpressure valve on the side of the control diaphragm across from the inlet chamber receives fluid through the exhalation valve and when the p...
