' DEVICE FOR FEEDING ADDITIONAL OXYGEN IN REELY-PORTABLE RESPIRATORY i APPARATUS.
y Application led February 6, 1926, Serial No. 86,500, and in Germany February 9, 1925.
The invention relates to a device for feeding additional oxygen in freely portable respiratory apparatus comprising a by-pass for the pressure reducingvalve and a. selfclosing valve which can be opened from outside by a. push-button. The object of the present invention is to provide a device of this kind which both in construction and in operation is materially simplified. WVith l this object in view the multiway connecting of the multiway connecting piece and connected with the said by-pass, which port is normally or automatically closed by a Hap valve adapted to be opened by the pushi button. v
The apparatus illustrated in the drawing is shown by way of-example. v
Fig. l is a sectional side view of the apparatus, the oxygen reservoir being shown broken off.
Fig. 2 is a view at right anglesto that of Fig. 1, and
Fig. 3 is a perspective view of the respiratoryapparatus carried by a person.
The apparatus illustrated in the drawing is 'a pulmonary automatic contrivance having means for a constant dosing of oxygen,
the invention, however being also applicableJ to other breathing or respiratory apparatus, in which an additional amount-of oxygen is fed to the breathing channels or members.
The cylinder or bottle 2 constituting the oxygen reservoir can be closed in the usual manner by a valve handle l which projects forwardly' when the device is carried as shown in Fig. 3 so that the handle may be easily operated. The oxygen bottle is connected by the screw nut 3 withthe multiway/connecting piece 4 leading to the usual pressure reducing valve 5 and extending Two pipes 6 and 7 connect the latter with the breathing bag (not shown). One pipe 6 serves for constantly feeding or dosing-oxygen and the other 7 for a pulmonary automatic dosing. A pipe 8 connects the multiway connectingr piece 4 which has a substantially cylindrical shape with a pressure indicating device.
Laterally to the piece 4 is arranged the low pressure chamber 91 the housing 9 of which may either be fastened to the pipe 4 by suitable means or may be integral therewith. In the construction shown the housing 9 is screwed to a socket 10 mounted on the piece 4. The wall 11 of the multiway connecting piece has a perforation or port 12, the mouth of which protrudes to form a seat 121 for the valve 1nember13 for closing the port. This valve member is mounted on a bell crank lever 15 pivoted to the housing b y a pin 14. The housing 9 has an angular elongated shape so as to form a prolongation 16. Into this prolongation the arm 151 of the lever 15 proJects. A spring 17 pressing or welding or it may be integral therewith by being made of one piece. A push button 20 is provided to engage the knob 19 and held in position by a curved diaphragm 21, which bends downwardly, when pressure is applied to the button. Thus by pushing against the butt-on '20 the valve 13 will be opened to allow oxygen to be fed from the multiway connecting piece 4 into the low pressure chamber 91 by way of the port 12. The chamber 91 communicates with the pipe 7 by the by-pass pipe 22 shunted across the reducing valve thus forming a by-pass for allowing a pulmonary automatic dosing of the oxygen fed to the breathing. bag without passing the reducing valve 5. The housing 9 has an opening opposite to the port 12, which opening is closed by the removable cover 23. Thus the chamber 91 and the valve 13 are accessible.
In the position of the apparatus shown in Fig. 3 the direction and position of the low pressure chamber 91 onfthe apparatus is so chosen, that the wearer may conveniently operate the push-button by his hand or thumb. The housing 9 projects substantially in the same direction asfthe handle 1 of the oxygen bottle and, consequently the pushbutton faces in this direction also.
1. In a self-supporting respiratory apparatus, the combination comprising an oxygen bottle with a projecting valve handle for the oxygen control, a pressure reducing valve a multiway co'nnectlng piece of sub stantially cylindrical shape having one end connected with said oxygen bottle and the'- other end with said reducing valve, said Apiece extending transversely to the axis of said oxygen bottle and having a port with a protruding mouth, a valve housing Vremovably attached to said connecting piece, so as to project laterally thereof in substantially the same direction as said handle and so as to cover said mouth a valve controlling lever pivoted to said housin within the same, a valve member carriedllny said lever in a position opposite said mouth, resilient means tending to press said valve member againstsaid protruding mouth, a push-button operativel associated with said lever and so inserte in said housing as to face in substantially the above mentioned direction, and a by-pass conduit, connected to said housing and shunted across said reducing valve.
2. Thefcombination set forth in claim 1 in which said housing has an elongated `angular shape and is coextensive with said lever in an axial plane of said multiway connecting piece.
In testimony whereof I have signed my v name to this specification. u
ALEXANDER BERNHARD DRAGER.
