SYRINGE 'Application Vled March 31, 1926. Serial' No. 98,731;

This invention relates to syringes and more particularly to mechanicallyl dilated vaginal syringes. n The objects of the invention are to provide la syringe of this character wherein `the mechanical dilation may beA secured by relative movement of freely slidable parts; to employ flexible fingers for dilation by said,movabley parts; to employ fingers which may be ready lo ily made of such materials as molded rubber;

to minimize a numberA of partssand enable the and to obtain' other advantages and results as'may'be brought out in' the vfollowing de-y scription.

Referring tothe accompan ing drawing in lwhich like numerals of re' erence indicate similar parts throughout the several views:

' Figurel is a side elevation of a syringe' and body of my invention; l

Figure 2 is a longitudinal section throughA :zo the said syringe on line 2-2of Figi;

Figure is asimilar sectional view showin the fingers dilated; l j

'figures 4 and 5 are sectional views corres onding to ed construction;

Figure is an end view-looking toward the top of Figure 5; an

Figure 7 1s a similar view with then/'fingers Ipartially rotated so as to increase the effective number thereof.- I v J In the specific embodiment of the invention illustrated in said drawing reference nu meral 1 indicatesan outer body portion which is preferably elongated and tubular and slidv abl mounted upon an inner body portion 2 which is likewise tubular and` equipped lat one Vend with beads '3 'for receiving and holding Va .water tube not shown): as to enable a supply of Vwater to, e' passed through the said inner body member 2 as iskusuai in syringes. The

FiguresQ and 3, showing a modi-v other end of said waterl tube is providedyv'ith a fountain head 4; suitably perforated so as to provide for proper spray when the water is passed through it. In the construction shown in the drawin this fountain head 4 is preferably screw-t readed on 4to the end of said body portion 2. VThe inner body portion is preferably longer than the outer body portion and in sliding tlereony is limited in.

movement by an outstanding shoulder 5 near the beaded end of said inner body member,

andlimited-'in movement in the other direcj tion by said fountain head 4 which is larger ,than the inner bodyA member or the tubular passage of the outer body member.

Mounted on the end of saidr outer body member adjacent the fountain head are a plurality of ngers 6, said fingers preferably being made of resilient rubber` with an inte-- gral collar or band which will frictionally slip onto the said outer body member and retain said fingers fixed thereto. The resiliency of\the fingers, is such as to normally position the same side by side longitudinally against the inner body member or water tube. When the body members are slid with respect to each other so as to' force thel fountain lhead of the inner body member toward the end of the outer body member, said fountain head pushes the ends ofthe fingers outwardly and continued sliding of said body members will cause said fingers' to extend radial directions with respect to the said body members, this position being clearly shown in Figures 3, 5, 6 and 7, and for brevity being called herein the dilating position. l

' In Figures 5,' 6 and 7 I have shown a construction wherein a double set of fingers may -bedilated, and in said figures the reference numeral 7 indicates 'an inner body member slidable with respect to an outer body member 8. The inlier body member 7 -isv provided with a fountain head9, and between said fountain head and the end ofthe outer body members is a rider lOfreely slidableupon the said inner body member. Above and Mbelow said rider with their free ends toward the rider are a plurality of fingers 11, having Aan integrai band at their ends away from the l rider by means-of which Said fingers maybe frictionally carried by the body members. The fingers carried b the inner 'body member are shown as mounte upon the fountain head .which in turn is threaded or otherwise carried by the inner body member. As'the fountain head in this construction is given a relativey movement toward the end of the outer body member the fingers on opposite sides of the rider engage said rider and are forced outwardly, the rider centering between the two sets of fingers. In this connection it may be observed that the fingers of the two sets may be in registration as clearly shown in Figures 5 and 6, or one set may be rotated so the fingers of that' set will radiate between the fingers of the other iset, thereby increasing 'the effective number of fingers as clearly J shown in Figure7. i

In both constructions, the-perforations in the fountain head are preferably arranged so as to'provide a stream adjacent the lingers when dilating, thereby shoot-ing the sprayin I a direction somewhat rearward with respect to the bodyport'on sov as to cause the water to go backwardly'between the fingers as well as radially outward in the direction of the fingers.

.Obviously other detail changes and modifications may be made inthe construction and use of my improved'syringe without departing from the spirit and scope of the invention disclosed7 and I do not wish to be understood as limiting myself to the exact construction except as set forth in the following claims l when construed in the light of the prior art. Having thus described the invention, vIv claim 1. A device ble with respect to each other, and resilient fingers carried by oneof said body members positioned entirely back from the outer endy of the other body member and adapted to be engaged bysaid other body member and bent outwardlyby virtue of the inherentresiliency ofsaid fingers when the said body members are slid with respect to each other in one direction with said bent fingers still positioned entirely back from the outer end of the said body member engaging the fin ers. 2. -A device of the character descri ed comprising an inner body menber having a-founl tain head, anouter body member slidable on :the inner body member, resilient fingers mounted on the outer body member entirely behindsaid fountain head adapted to be en, gaged by said fountain head and bent outwardly by virtue of the inherent resiliency of said fingers when said fountain head @is slid toward and between the Asaid fingers with said bent fingers still positioned back of the said fountain head.

3. A device of the character described comprising an inner body member havin a shoulder at one end and a fountain lhea at of the character described comprising inner and outer body members slidaresilient dilatino` fingers mounted on the end of said outer body member next the said fountain'head, said fountainheadtand body member being slidable between saidfingers so as to bend the same substantially at4 the j unction .thereof between the fingers and thevbody member therebycausing the fingers to stand outwardly in a substantially radial direction with respect tothe body members, the resiliency of said fingers automatically returning the same toa position close to the body mem ber upon return of the body members to the starting position. l

e 5. A device of the character described com-` prising an inner body member and an outer body member slidable upon said inner body member, resilient dilating fingers mounted on one of said body members and operable by sliding said members from normal positioan, said resiliency of said fingers operating to normally returnlthe body members to said' initial position upon displacement of said members in use.
