Aplilication Y 6 Claims.

This invention relates to certain novel improvements in.v cervical applicators, and has forits principal object the provision of an improved construction of this character which will be highly efficient in use and economical in manufacture.

Other objects will appear hereinafter. vThe invention consists in the novel combination and 'arrangement of parts to be hereinafter described and claimed.' v

'The invention will be best understood'by reference to the accompanying drawing, showing thepreferred form of` construction and in which: Fig; 1 is a plan View of the new applicator; Fig. 2V is a longitudinal sectional view of the same on' line 2-2 in Fig. 1; r4Fig. 3 is atransverse sectional view' on line 3-'-`3 in Fig 2; and,`

Fig. 4 is a fragmentary sectional detail view. n 'The newapplicator comprises a barrel includinginner and outer concentric tubular passages 10 land, 11; the inner tube 10 having an enlarged externally threaded end portion 2'7 to which a cervix' gripping member inthe form of a suction .A cup 1'2 is attached, the suction cup 12 being adapted kto grip the cervix under .the force of negative pressure applied thereto in a manner presently to be described.

Threaded onto am that is opposite the end tion 27 is a valve bushing mounted-a valve core 13. Provided in the valve core 13 are two non-communicating ports 14 and 1,5 which extend transversely therethrough at 35 right'angles to Veach other.

A' kclosure nipple 16 is air bulb 1'9 at lits'outer end, including expanders elements mounted in 19'in the formof spring y inthe drawf the bulb in the manner illustrated Provided in the nipple vstem 17 is a passage 20 e (Fig. 2) which communicates at its inner `end with both barrel passages 10 and 11. 1

` Providedin the outer end of the air bulb 19 is an air inlet 29, adapted tobe vclosed by a valve structure 29', providing a valve seat 22 (Fig. 2) against which an air Valve 23 is adapted to seat when the bulb 19is compressed; the valve 23 being unseated by atmospheric pressure from outside the bulb when the bulb 19 is released and expanded from compressed position.

Extended through the bushing 24 are two pasthe end of the'inner tube 1o` having the enlarged por 24 inwhich is rotatably y detachebiy threaded into the`valvebushing 14and has `a stem` 17 to which' v Which Naikelis, y

sages/25 and30v which provide for selective communication betweenthe outer barrel passagelll" and thenipple stem passage 20 and between the inner barrel passage 10 and the nipplefstempas-i sage 20. Formed in the enlargedportion 27 fof the inner barrel passage 10 is a passage 28 whichy opens at its outer end into the suction cup 12 andI at itsinner end into the bore of theouter barrel passage 11;

` To apply a medicament tothe cervix the nipple plug 16 `(-Fig.f2) is unscrewed land a container 26 (Fig. 4) of medicament is attached to the valvel bushing 24 in place of the plug 16. The valve core 13 is then positioned so that the port 14 in registration with the passage 30 and rwith the inner barrel passage l0; in which position of the valve core the port'l is out of registry with the passage 25.V The tube k26 is then compressed toi inject a suitable quantity of medicament, which maybe a medicament jelly or the like, into the inner barrel passage 10.

The valve 13 is then turnedto position the port 14 out of registry with the passage 30y to close on" the inner barrel passage r.10. In' this position oi the'valve core 13 the port l5 is in registration with rthe passage 25 and outer barrel passage 11. The tube 26 is then detached from the valve bushing 24 and the nipple plug 16 reattached thereto as in Fig. 2. i Before detailing the function of our invention it is important to note that to assure proper results the cervix must be held stationary the air therefrom withdrawn. This withdrawal. of the air from the. cervix creates a negative pres-r sure, thus holding the cervix in` alignment 'with' thechamber containing medicament in the cervi-v cal applicator.

The operation of our invention` is as `followsr The air bulb 19 is manually compressed against the action of the expander springs 19. The valve. 29' is in a closed position.A The cup is now applied f to the cervix, after which the bulb?y is permitted to expand its maximum by virtueof the expander springs to assure partial vacuum. This expansion' of the bulb creates a partial vacuum in the line includes the suction cup 12, passage 28, outer barrel passage 1,1, the passage 25, port 15, nipple20, tube 18, and air bulb 19. `After cornpression of thebulb 19 and with the cup 12 in applied position bulb 19 is permitted to expand, and this expansion of the bulb 19 draws the air out of the cervix, thus preparing the cervixfor the next operation, which is the injection of the medicament.`

50 r with respect to the cervix, the i e This injection of the medicament is accomplished in this manner: The medicament which is confined in the barrel 10 is injected by turning the Valve core 13 to register the port 14 with the passage communicating with the valve 10, and to move the valve port 15 out of registry with the passage 25. After this has been done, and the air inlet 29 opened, the air bulb 19 is compressed to eject the medicament from the inner barrel 10 into the cervix and thereon.

While we have illustrated a bulb 19 for the purposes herein set forth, it is manifest that if desired any bulb of a well known structure may be substituted for this bulb without departing from the spirit of the invention.

Having thus described our invention what we claim as new and desire to protect by Letters Patent is:
