SYRINGE.

Application filed November 6,1925. Serial No. 67,331.

This invention relates to syringes, and more particularly to a syringe specially adapted for use by Women.

One of the main objects of the invention is to provide a nozzle and means associated therewith which will insure a thorough cleansing action. A furtherobject is to provide means associated with a nozzle which can be expanded, after insertion, so as to u; spread the parts and expose the same to the action of the sprays of water or a solution discharged through the openings of the nozzle. A further object is to provide expandible spreading means so associated with the nozzle as to be contracted while the nozzle inserted in position for use to facili tate withdrawal of the nozzle and effectually eliminate possibility of pinching or injury to any of the tender parts of the wall of the cavity into which the device is inserted in use. A further object is to provide a nozzle and associated parts of the character stated which can be produced at relatively low cost. Another object is to provide simple and eiiicient means whereby the water discharged fromthe nozzle can be collected and led otf through a discharge tube. Further objects will appear-from the detailed description In the drawings: v

Figure 7 is a. plan view of the complete device; y I

Figure 8 is a section taken substantially on line 8-8 of Figure 6;

Figure 9 is an enlarged section taken on line 9-9 of Figure 1. The device includes a nozzle 1 provided at one end with a gripping elementor knob 2. from which extends a corrugated nipple 3. This nipple is adapted for reception of a flexible tube 4 which may be connected to a small tank or container supported in an elevated ositlon, or other suitable means, for supplying water or a solution to the nozzle under pressure. Portion 1? of the nozzle adjacent -ltnob2 is of cylindrical cross-section, the central portion of the nozzle being of approximately square cross-section with" a longitudinally extending rib 5 at each cornor, as illustrated in Figure 5. The spaces 6 between ribs 5 provide passages for the flow of the water or solution discharged from the nozzle downwardabout the same. The other end portion 1" of the nozzle is of cylindrical shape and terminates in a head 7' closed at its outer end and provided with suitably spaced anddirected spray openings 8 communicating with the interior or base 0? the nozzle. Head 7 is provided in its outer surface with four equally spaced V shaped grooves 9 extending longitudinally of the head and intersecting at the tip or apexthereof. This nozzle and the knob 2 andnipple 3 are preferably formed inte-- grally of hard rubber, though any other suitable or preferred material may be used.

Thenozzle is slidable through a thick ring or collar '10 of hard rubber, the outer surface of which is preferably knurled so as tobe readily gripped. A reduced neck 11 extends fron'rthe inner endof'collar 10 and fits tightly hrougl'r thebottomof a receiving cup or basin 12 of hardrubber. This cup is elliptical. shape in plan view and is slightly curved downwardly and outwardly in the direction of its length to Conform, approximately to the shape of the portion of the users body against which the cup is pressed in use. The cup is provided at its upper open portion or top with an inwardly turned retaining flange 13 the outer surface of which is smoothed and rounded to prevent injury or discomfort to the user. An outlet nipple 14 extends from that end of the cup which. in using the device, is the lower end and is adapted for reception of a flexible tube which, in practice, communicates with at suitable receptacle.

The neck 11 is provided with four arms 16 formed integrally therewith and disposed in spaced parallel relation. These arms extend in the direction of and surround nozzle 1. Each arm is provided, at its free end, with an inwardly projecting head 17 of segmental shape the apexes or edges ofwhich fit into grooves 9 of head 7 of the nozzle when the nozzle is in its inner operative position. The arms, being formed of hard rubber, possess appreciable inherent resilh l and these arms serve to open or *spreadthe ency which acts to urge the arms toward each other-and to hold the heads 17 in proper engagement with grooves 9. As will be noted more clearly. from,Figure 8, the inner conform to the bore ofe'bllar 10'. When" the nozzle is drawn outwardly arms 16 move toward each other into substantially the positions illustrated in Figure 6. Outward movement of the nozzle is limited by ascrew Iii-secured therein and projecting beyond the nozzle between two of the arms 16 for contact with neckll. This screw is so positioned that whenthe nozzle is intits outermost position, the inner end portions of the heads 17 Yengage into the grooves'9 at the tip of 'nozzle head '7. This ensures'proper register of the apxes of the heads with the grooves-so that these heads will be held in their proper relative positions" and will be spread apart radially-of the nozzle when the nozzleismovedinwardly through collar into its operative position.

In usingthe device; the nozzle is moved into its outermost position permitting the armstoniov'e toward'each other, and the devicej is then inserted.- After the device has been fully inserted, tlie'nozzle is' moved inwardly through collar 10 into itsqinnermost position. This forces thearms apart parts so as toexpose the'sanie to the action of thefspraysof water or solution discharged through openings '8. During the flow of water or-solution'through the nozzle, the cup 12 is held prssedffirmly a'gainstthe user-s bodyso as to form aclosure therewith about the. lower portion of the" nozzle. 1 The water or solution discharged ir'om 'the nozzle will flow downwardly aboutthe same "and betwicen the arms 16 into thecup'from which itis discharged through nipple 14 and tube" 15. Cylindrical portion I? of the nozzle fits snugly through collar ilO, and knob 2 its closezagainst thecollar when the nozzle is in itsinner'position. Thisctfe'ctually prevents any leakage between the nozzle and the collar;

Due torthec factthat the outer surfaces of heads 17 of arms 16 are roiind'edand are spaced'a slightdisfianc' apart when in'closed or 'normalposition, all po'ssibility of catching or pinching of the parts being treated is eliminated. The deviceconstru'cted in this manner-is'veryelficient in use,will not cause injurv 'ordiscomfort to theuser, and can be satisfactorily used without any necessity of aipan or a bowl, or other" receptacle being placedunder the device when in use, which is an important consideration; and great conv'eniencen y a KWhile lwe prefer to use hard rubber for claims, in this application in which a proferred form only of our invention is disclosed.

Vhatwe claim is: a 1. In a device of the character described, a collar. having resilient arms extending from one end thereof and disposedin spaced parallel relation, and a nozzle slidable through the collarand between the arms, 1

said nozzle being provided at its inner end with spaced grooves extending longitudinally thereof, the arms beingprovided at their free ends with inwardly projecting elements engaging into said grooves and disposed to spread the arms apart when the head of the nozzle is positioned betweenthe free end'portions of said arms. as

described,

2. In a device of the character a collarhaving resilient arms extendin from one end thereof and disposed in space parallel relation, and a nozzle having limited movement through-the collar in either direction and operatin between said arms, s'aid nozzle beingiprovided in'its inner end with spaced grooves extending lon itudinally thereof,. the'armsbeing provi ed at theirfreef ends with heads of approximately segmental cross-section projectinginwardly beyond the inner faces of the arms and hav-T ingtheir. apexfes held in: engagement" with said grooves by the resiliency of saidoarnis.

' lira device of the vcharacter described,

a collar provided at one end with a reduced neck, a cup having its bottom wall fitting, a

snugly about said neck and being adaptedat its inneirend to fit snugly against the users body, a nozzle slidalile throughthe collar and having a knob adjacent its outerend disposed to contact with the collar when the nozzle is in its innermost position, the nozzle fitting snugly through the collar and being provided with a nipple at its outer end, resilient arms extending from the neck in spaced parallel relation-,the nozzle operating between said arms and the nozzle and arms'having cooperating means for spreading the arms apart whenthe nozzle is moved intoiits' innermost position, and outlet means extending from the cup.
