APPLICATOR.

Application filed March 7, 1927; Serial No. 173,575.

My invention relates to improvementsin applicators which are adapted for theapplication of medicine, and it. consists in the combinations, constructions, and arrange ments herein described and claimed. D

An object of my invention is to provide an applicator by means of which a medicine maybe deposited within the. vagina adjacent the uterus. I

A further object of my inventionis to provide a device of the type described which" may be readily inserted in the vagina and 7 have its inner extremity positioned adjacent the 0s uteri and which is of asufliclent size to prevent any backflow of'the 'medicine that is deposited. r v A further object of my invention is to provide a device of the typedescribed which contains enough medicine for several applications. j j V v I I A further object of myinvention is to provide a device of 'thetype'described which if desired it may be'used in small inconvenient places, such as washrooms onxtrains.

Other objects and advantages Wlll appear in the following specification, and the novel features of the invention will be particular- .ly pointed'out in they appended claims.

My inventionti's illustrated in the'accompanying drawings, forming a part of this application, in which: 3 V

Figure l is a vertical section through one form of my invention, as applied to" the uterus.

Figure2 is an end elevation of the form shown in Figure 1,

Figure 3 is a vertical'section through another form of my invention, and

Figure 4 is a fragmentary elevation of the iormshown in Figure 3.

In carrying out my invention I provide a cylinder or barrel 1 having a threaded end 2 and a threaded end 3, see Figure 1. A cap 4: having a concave end 5 and a centrall disposed threaded opening 6 18 provided with an internally threaded portion 7 which-Y I is adapted to'receive the threaded end 2. f

The cap i is provided with a tapering wall 8 and arcuate' shaped grooves 9 which extend.-

from'the tapering wall 8to the "openingd,

A plug 10 is provided witha threaded shank. lljwhich 1s receivable in, the opening 6 when is being filled with a 12.

After the desired amountof medicine has been d sposed in the cylinder a fi atin'gpis .rnedicine indicated at.

ton 13provided with concave'su'rfaceslt and the device is not in use'or when'the cylinder ton 13 is slidablydisposed thereimjTheYp s- 1a. A piston pump which iscom posed o'f-a, plston head 16 an'da valve 17 is disposed in" the cylinder 1. The piston "head"16ispro! 'vided with concave surfaces 18 and 19, and a j centrally disposed opening 20. 5 The val'veg i" 1 7 is disposed in engagementwith thepiston head 16 and is adapted to close the'opening 20. A cross shaped stop member 21 is sea cured to the valve for 'apurpose hereinafter described. A rod 22 extends through an opening 23 in a t0p24; and has its ends rig idly secured'to the valve [head 16 and a thumb screw 25; The thumb screw-.25 is provided with a threaded shank 26 which isadapted to be received in the op ening"23. Y

The .top 24; is provide d'with'an internally ed endj3'of the cylinder 1.

threaded portion 27 for receiving the thread "From the foregoing description of'the va-- rious parts of the device, the 'operation there of maybe readily understoodQj Let 'us' a sume that the cylinder 1 is approximately l With he medicine;12,that the pl g 10 is disposed in the'openin'gh. and that the threaded shanlz' 26' is" disposed in, the open ing 23; This is the position of thedevicefl when it is not in use. In using the 'device," "however, the plug 10 is removed, thenby removing the thumb screw25 from the top 24" the piston pumpfmay he movedYout-Q wardly' until the piston 'headflfiis ens gagement' with the. 'top Y 24. During this" movement of the piston valve'the valve'lfZ moved away from the opening 20 thusiper f mitting airto pass through this opening,

around the prongs ofthe cross-shaped mem-f ber 21, and into the cylinder. The device is now ready to be inserted into the vagina through the external orifice until the cap is in contact with the os uteri or mouth of the womb, see Figure 1. When this position has been reached, by forcing inwardly upon the lllJl A thumb screw 25, an air pocket is formed between the piston head 18 and the piston 15, due to the closing ofthe valve 17, and the floating piston 13 is moved inwardly. The

inward movement of the floating piston causes a portion of the medicine to pass outwardly through the opening 6 and in engagement with the 0s uteri. A portion of the medicine passing from the opening 6 will pass through the grooves 9fand be distributed over-the 0s uteri.

Each movement of thepist-on valve moves the floating piston inwardly, thus increasing the air-pocket and decreasing the amount' I of medicine. If'one movement of the valve doesfnot extract enough medicine the piston valve"may"be drawn outwardly again and then again forced inwardly.

In Figures 3 and i I have shown a modified formof my device which. is-composed of a" cylinder 30with a somewhat pointed arcuateshaped'end 31. v v The end 31' is provided with grooves 32 which extend from sp'aced-apar'ts adjacent the outer extremity thereof to an opening- 33. 'A co'ver 3 l having a central threaded opening 35.-is disposed upon the opened end ofthecylinder 30., A medicine 36 may be disposed in the cylinder 30. having a central threaded openingis then disposed [in the cylinder" 30. A threaded rod 38 extends through the opening in the piston 37 and is provided with a thumb screw 39 having a threaded shank 40, which is receivable in theopening 35 of a top 34.

v In Figure 5, I have a diagrammatic view of the cylinder 30 and the manner in which the end 31' conforms to the 0s uteri when placed within the vagina. By unscrewing the rod 38 a desireddistahce'the piston 37 may be forcedinwardly'thus forcing a portion of the medicine 36through the opening 33and distributedover the 0s uterithrough the'jgrooves' 32. v I

When the form shown inFigures 3, 4;, and 5 is not in use therod 38 is forced'inwardly until, the disc 41 engages with the opening 33 and thethreaded shank isreceived inth threaded opening 35.
