j' FLUID-PRESSURE DEVICE.
Application filed liarch 27, 1922. Serial No. 547,809.
tain new and useful Improvements in a" Fluid-Pressure Device, of which the followin is a specification. lhe main object of 'my invention is to provide in a. fluid pressure device improved means for creating and maintaining pres sure in the device by means of compressed air.
Another object is to provide an improved form of expansible air chamber. 1
Another object is to provide a flexible bag contained within the device and having means for admitting air to. the interior thereof. Another object is to provide means for preventing the bag from, being ruptured by being forced through an aperture of the device under pressure within the bag itself. lVith these and incidental objects view,
26 the invention consists of certain novel features of construction and combination of parts, the essential elements of which are hereinafter described with reference to the drawing which accompanies and forms a part of this specification.
In the drawing Figure 1 as a longitudinal section of my improved device and Figure 2 is a section taken onthe line 22, Figure 1.
As shown in Figure 1 the barrel 1 has an intcriorly threaded aperture 2' at one end thereof to which may be connected a hypodermic needle, a tube for connection to a hypodermic needle, or there may be connect- 0 ed thereto any device for which this partie ular construction of fluid pressure device as applicable:
The other end of the barrel 1 is closed by a cap 2 threaded to the barrel at 3.
Hold between the barrel 1 and the cap 2 is a flexible bag 4 having a bead 5 about the perimeter of its open end.
The/cap 2 is threaded at.6 to receive a check valve 7 of ordinary construction.
At the other end of the barrel a guard disk 8 is provided and this disk is mounted at 9 to the barrel 1 and has sufficient resiliency to normally maintain a position such as that shown in Figure 1, but is of such a strength that when the end 10 of the bag 4 impinges on-the surface of the disk 8 when the bag 4 is expanded, the disk is forced down against the head end of the barrel and closes the aperture 2', thus preventing the bag 4 from expanding into the aperture 2' and thereby rupturing itself at that point.
In use the barrel 1 would be filled by fluid which was to be expelled under pressure. The end of the cap 2 is then placed over any suitable source of air pressure and the air therefrom is admitted to the interior of the bag 4 through the check valve 7, creat-ing a pressure on the interior'of the bag of a hundred pounds per square inch or whatever pressure may be desired, and it is evident that this pressure will be exerted against the liquid or fluid in the barrel 1.
en a portion of the fluid is allowed to escape through the aperture 2', the bag 4'will expand and fill up the space left by the escape of the fluid, and it is evident that if the bag 4 is of sufficient flexibility and resiliency and is properly proportioned with regard to the size of the barrel, all of the fluid may be expelled from the barrel under a considerable pressure, the bag 4 expanding so as to entirely fill the interior of the barrel 1.
The barrel l may be filled by placing the tip 2' into the liquid which is to be drawn into the barrel while the bag 4 is expanded, and then by releasing. the check valve 7 the fluid will be forced into the barrel 1 by atmospheric pressure as the bag 4 diminishes in size on the decrease .of the air pressure within.
When used as a part of or with'a complete connected hypodermic syringe it is evident the desired pressure may be established in the barrel and that this pressure will be maintained almost indefinitely so the operating physician can have the instrument at v hand and be certain as to its operating efliciency during an operation. and will also be certain that the-device will expel up to the last drop ofthe fluid in the barrel without any action on the part of the operator except the releasing of the liquid by any suitable means through the aperture 2'.
While I have described my invention and illustrated 'it in one particular design, I do not wish it understood that I limit myself to this construction, as it is evident that the application of th inven i n may e varied in many ways Within the scope of the following claim:
In a fluid pressure devlce the combinatlon of a barrel, :1. flexible baghaving a bead 5 around the perimeter 9f. its 0 eniend, a cap for one end of said barre, said cap clamping the bead of said bag against the end of said barrel, a checkwalve leading from the exterior of said cap to the interior of said bag, and 'a guard positioned 10 for clbsing an aperture in the opposite end of said barrel against the upper end of said bag when expanded. t
