(c1. 12s-27s) The linvention'rel'ates vto surgical .suction apparatus 4and has as an object the provision of a devicev of this character that .may be produced .at avery much lower cost than devices .now onthe market for the purpose.
1 It is a further object oi the .invention to provide apparatus of this character that shall have substantially no Vfrangible parts; `one `'which may be packed in 'a very compact package, and which because of vthese qualities. will be especially :useful in army, navy., or .wilderness use generally.
Further objects ci' the invention will .appear from the following description when .read in connection with the accompanying drawings showing illustrative embodiments of the invention, and wherein:
Figure 1 is a side elevation of the apparatus as it will appear in use;
Fig. 2 is a vertical section showing one portion of the apparatus packed in another portion for carrying;
Fig. 3 is a plan view showing a form of clamp band;
Figs. 4 and 5 are vertical transverse sections drawn to an enlarged scale showing a valved connector and a plain connector respectively;
Fig.. 6 is a detail vertical section of an end closure for one of the parts; and
. closing valves 32, 33,
Fig. 7 is a like view of an end closure of another y part.
After surgical operations it is frequent for a patient to become distended with gas, to his great discomfort, and it is the practice to insert a tube, usually through the nostril, into the stomach, and even into the small intestine. Such a tube is .shown at Ill with the partsof the body through which it is inserted shown diagrammatically. The tube l leads to a chamber I I for reception of gas or any liquids that may be drawn 01T, entering the chamber by means of a connector I2 shown enlarged in Figure 5, as comprising a screwthreaded exterior i3, a connector for the tubing M, a tubular portion I projecting into the chamber and an outlet I6 having a portion l'I to which a suction tube I8 may be attached.
The suction tube I8 leads to suction device I9 shown as suspended from the bracket by means of flexible members 2l. To measure the amount of reduced pressure produced by the device I9, the tube i8 is shown as equipped With a Y 22 one branch of which is connected to tube 23 which in turn connects to a manometer 24.
The suction device I9 is shown as provided in the form of a collapsible bellows-like chamber having upper and lower closure plates 25, 26,
lshown in detail in Figure i6. The lower of these plates is shown asprovided with a hook 2l upon which weights 28 may be hung to increasethe suction 'and by varying the number of weights suspendedmay determine the amount of suction., as indicated on the manometer v24.`
For convenience, but not essentially, the closures 25, 26 are .formed with a circumferential groove 29 and the upper .and lower ends ofl the collapsible member I9` are .shown as clamped in these grooves by .means of a screw clamp member 3B, as .indicated 'in Figure ;3. If desired, reinforcing strips 43 may be .provided in the bellows I9 to take the weight of the` plate 26 or -of weights lsuspended therefrom when the bellowsis :fully extended. Y
The form of clamp band shown is only for purposes of illustration as some other form of connection, quick detachable, cam, or toggle-operated clamp, may desirably be substituted therefor. Also if it is desired the closure plates 25, 26 may be made permanently attached to the member I9.
A plug 3| for the top of member I9 is shown in Figure 4 as provided with inwardly and outwardly The valve 32 will close by gravity. Valve 33 is shown as provided with a light spring 34 to ensure its closure.
The tube I8 is to be-attached to the member 35 and the member 36 when used as shown is merely a vent. It will be seen that when the member I 9 has yielded to the suction so as to become fully extended, it is only necessary to push upwardly on the bottom of the closure 25 whereupon the valve 33 will closeand valve 32 will open to expel air from the chamber, and release of this upward pressure will instantly place the device into operation.
For compactness when prepared for transportation, the member I I is also shown as collapsible and in use it is supported by struts 3l which are desirably telescopic so that they may be folded into a small space and placed inside of the chamber II, This chamber is shown as having a closure 38 secured with a suitable gasket to make the same air-tight, by means of wing screws 39, or in any other desirable manner to provide an airtight joint.
Should the chamber I9 become damaged or lost, it is possible to place the plug 3l in the place of the plug I2 :and either dispense entirely with a chamber for II or improvise a chamber for this purpose out of a five-gallon can or a jug with a corkreceiving the tubes I Il and I8.
The bracket 20 is of course no necessary portion of the apparatus as the member I9, or Il if substituted therefor, can be hung upon a limb of a tree or a tentV pole or any other convenient ob- ,V dect. Y- Y vThe expense of usual devices forthe purposes of the present invention is such as to makeit prohibitive for small hospitals to supply as many as theyljshould have. i Since the present device can be. constructed at a fractionrof such cost,
every hospital can have a liberal number. In use the device has been found to be very flexible,n conf "l venient;` and efficient.
In the operation of the Ydevicelvvii'h thettube l0 in place and the apparatusy arranged vas illus.-
trated, the attendant will merelyglift the plate V2li and Weight 28, and release the same. K Airc'zomy pressed in the space within the chamber I9 will N forcer valve 33 closed aided by spring 3'4 and open valve 32. When the plate is released suction will 'Y begin at'once with reversal of the valves 32, 33
" and the vacuum createdrwill be determined by the amount Aof VWeight 28 and indicated on the device 24. ,n I f, The timerduring which the device Will operate Without attention will be determined, otherrthings being equal, by the volumeof the'chamber i9.
VIt'rgxraln be increased in either diameter or length to increase the period of operation.
`The chamber Vlll-may be suspended asshown, or vfrom theY limb of a tree, or from a tent pole, or afhook qcan beV applied to an uprightV of a bed-'- stead 'for its support. Because of its adaptability andfcompact packing possibilities it is capable of a widerange of service in war or in peace.
Minor changes maybe made in the physical embodiments of the, invention within the scope comprising, in'coxnbination: a plate manually restrainable to remain stationary against move-V 2,397,257 Y l .of the appended claims without departing from Y the spirit of the invention.
