SYRINGE Filed Aug. 31, 1929 Kamek/c/r/ 773/070 dbtozmaq Patented June 10, 1930 UNITED STATES KAMEKICHI TOKITA, OF SEATTLE, WASHINGTON svRINeE Application filed August 31, 1929. Serial No. 389,650.
This invention relates to syringes and pressure chambers and particularly to such devices for forcing liquid in various directions.
In the use of syringes for surgical purposes and for various other purposes it is important that no air be driven from the receptacle while liquid is being forced therefrom, and it is important to be able to force liquids upward and downward while the chamber may be partly filled with air, it is also important to be able to fill the chamber entirely full of liquid by suction.
An object of the invention is to provide a collapsible bag or receptacle which may be completely filled with liquid by suction through a tube extending therein and there from;
A further object is to provide such a bag or collapsible chamber, for forcing liquid downward and upward therefrom, while the upper portion of the chamber is filled with air;
Another object is to provide such a device for forcing therefrom all the liquid contained therein, in various directions while a portion of the chamber contains air, and to provide that none of the air shall be discharged from the receptacle until the liquid supply has been exhausted therefrom.
With these and other objects as may appear from the specification hereinafter set out, I have illustrated my invention by the accompanying drawings, of which:
Figure 1 shows a front elevation of the clevice, with a part of the nozzle broken away;
Figure 2 shows a detail View of the collar and cap attached to the head portion of the bag, with alignment grooves on the cap and collar;
40 Figure 3 is a diagrammatic view of the device, when used for forcing liquid upward, while the upper portion is filled with air;
Figure 4 is a diagrammatic view showing the discharge of liquid downward from the chamber while air is contained in the upper portion thereof, and
Figure 5 is a view showing the bag being entirely filled with liquid by suction from a source of liquid in another receptacle beneath. 9 Figure 6 shows another form.
i in the walls of the tube 10 at Like numerals on the different figures represent like parts.
6 represents the walls of the bag or chamher which is preferably formed of soft rubber or other suitable flexible and air tight material so that the bag may be readily inflated and deflated by the pressure and release of the hands of the user on the outer surface thereof; 7 is a heavier or solid neck of same material with a hole therethrough 9, and over the neck is mounted a rigid cap 8, for holding the mouth thereof normally closed to apredetermined size.
An operating tube 10 is rotatably positioned through the mouth or outlet of the neck and is held from sliding motion by a collar 11 affixed thereto, and a small flange 12 around the inner end of the tube 10. A removable inner tube 13 is preferably connected by threads or otherwise to the inner end of the tube 10 for continuing the inner outlet thereof to a point near the opposite end of the bag, for the purposes as will be hereinafter shown.
Two opposite holes I l-14 are provided a point near the lower part of the neck, and coacting ducts 15l5 extend through the opposite walls of the neck piece from the upper part of the chamber in the bag to points in line with the holes in the walls of the tube, so that when so the holes and ducts are positioned in alignment, the contents of the bag or chamber may pass outward through the ducts and thence from the outer end of the tube 10. Corresponding grooves 16, 16 are provided in the outer edges of the cap 8 and collar 11 which are in alignment when the holes 14 and ducts 15 are in alignment, and the operator in order to close the outlet through the ducts merely gives the collar and tube 10, approximately a quarter turn; and to open the same the collar and tube are again turned till the grooves register. a
Considerable difficulty is ordinarily met in attempts to fill a rubber bag by suction from a lower source,- but with my device, when the inner tube is extended to near the closed end of the bag, and the ducts 1515" are closed the operator may compress the bag and then insert thenozzle or outer. end of the tube 10 in any liquid as 18 in the glass 21, then release the walls of the bag, and the liquid will be drawn up into the bag as shown in Figure 5. By one or more such operations the air 20 will be completely driven from the bag and the liquid completely fill the same. It being understood that the walls of the bag are of such thickness and resiliency thatthey will normally return to a globular or extended position when the pressure of the hand of the operator is released, and so'drawthe'liquid therein.
In order to force the liquid from the cham' her in an upward direction the operator then reverses the position of the tube and chamber as shownin Figure '3,andby, compressing the walls of the bag,'the liquid 18 may be forced fromthe lower portion or bottom of the chamher while abody of air as 20 is in theupper portionof thechamber Again to force liquid in a downward direction from the chamber, the position is changed so that the'tube points downward as shown in Figure 4:, and the tube turned till the openings from the ducts and the holes through the sides of the tube register and the liquid willthen flow freely from the chamber through the ducts and tube; and any additional' force may be given for spray or other- Wise by oompressingthe bag.
By the use of theinnertube and the carry-- inglof the outlet through-the tube thereby to a point near the closed end of the bag, it is found that" when the ducts are closed that will result from the bagWhen filled with liquid and laidliorizontally o'n'a fiat surface, as a table or floor, and'this feature "is found very important in doinestieand' hospital usage. a
- The outer extremity or end of the'tube 10 is not shownin Figure 1, but it may be bent in anyform or extend in a straight line, and be provlded with any preferred formation or means for'ad 'ustable extension.
In some casesIdo notirequire the ducts throughthe neck piece, and use only the tube extending through the neck to near the opposite end of the bag,'and form the outer end of the tube for a'short nozzle, and this simplifies theconstruction, and still provides the inner tubewhichtends to prevent leakage from the of the chamber and the outer end of the tube terminating outside the chamber holes in opposite sides of the tube and ducts extendingthrough opposite sides of the neck from the interior of the chamber to the opening in the neck in line with the holes in the tube, and means for determining when the ducts and holes are in alignment to register.
2. A pressure bag with resilient collapsible sides normally expanded, a tubular neck piece extended through the edge of the bag, a tube rot-atably held in position through the neck, with one end inside the bag and the other outside for an inlet and outlet for the bag, holes' in opposite sides of the tube, and ducts through the sides of the neck extending from the interior'of'thebag to the holes in the tube.
In testimony whereof I affix my signature.
