6 Claims. 1

This invention relates to vaginal depositors and applicators and more particularly to the type of applicator illustrated in myPatent No. 2,268,536.

The principal object of this invention is to provide an improved core or tampon which will produce further new and novel results.

My original applicator consisted of an ejector or receptacle holding a solid expellant or core and a positive means for the extrusion thereof from the receptacle into the required cavity and for the removal thereof when required.

This invention provides for the extrusion of a core cylindrical in external formation but which after extrusion can be spread open and unfolded after it has been properly located so as to expose and apply medication previously placed therein.

The object of my invention is to provide by such a device a means of self application of various medicaments at a location difficult of self administration.

In accordance with my invention there is produced a useful and practical device. It is easy to manufacture and low in cost. It is of simple construction and easy to operate. It is positive in action. It is constructed of materials which may be sterilized if required. The core may be extruded slowly from the mouth of the cartridge and held firmly in an extruded position so that thus poised positive application maybe made at the prescribed location, While at that location it may be mechanically unfolded and everted to release and apply such active substances as anaesthetics, antiseptics or estrogenic substances.

Further objects of the invention will'hereinafter appear from the following description of the preferred embodiments illustrative of the invention and shown in the accompanying drawing in which:

Fig. 1 is a front view of a core unfolded before rolling into a cylindrical shape showing the disposition of the combination traction and withdrawal loop to provide guide loops and draw string.

Fig. 2 is a front view of the core rolled into cylindrical shape and extruded from the mouth of the ejector tube before further traction unfolds and unrolls it.

Fig. 3 is a plan view of the core rolled into cylindrical shape.

Fig. 4 is a front view of the core extruded from the mouth of the ejector tube and partially unrolled, unfolded and everted by further traction on the draw string.

Figs. 5, 6, and '7 are front views of other methods of applying to the walls of the core before rolling, the cords of the traction loop so as to provide guide loops and draw strings for the traction loop.

The complete device consists of a -hollow tube, comprising a combined container and applica- (Cl. 128G262) tor into one end of which is fitted a snug fitting core or tampon to which is attached a combination traction and withdrawal loop so arranged that traction on the loop will extrude the core from the ejector tube while further traction will open and unfold and evert it for internal applications of'medicaments, the loop later serving as a means of withdrawal of the core.

Referring to the drawing, the device therein shown as illustrative of my invention comprises an applicator tampon fashioned from a fiat section of absorbent material I, with an upper edge or crown 2 and a lower edge or base 3, with longitudinal edges 4 and 5. A combination traction and withdrawal loop 6 is formed by joining the free ends of two draw strings I and 8. The draw string I may be attached to the outside wall at the point 9 which is adjacent to and spaced from the crown 2. The draw string 8 may also be attached to the outside wall at a corresponding point I0 likewise adjacent to and spaced from the crown 2. As a modification both cords may be placed over the crown 2 adjacent to the points 9 and I9. The guide loops II and I2 are formed on the outside wall adjacent to and spaced from the base 3 and directly below points 9 and I0 respectively. The cord I passes through guide means or loop I I while the cord 8 passes through guide means or loop I2. When the longitudinal edges 4 and 5 are curved backwards towards each other' a split tubular cylindrical formation is formed with point 9 substantially diametrically opposite point I'll and point II diametrically opposite point I2. The draw strings I and 8 hang downwards from points 9 and III, pass through the loops II and I2 and their free ends tied together to form the loop Ii. As indicated in Fig. 1, the loop 6 may comprise one continuous cord formed by the draw string 1 woven into or through the material at point 9, passing backwards, downwards and outwards to form the guide loop II, into the material, across and outwards to form the guide loop I2, into material, upwards and outwards at point In to form the draw string 8. Instead of separate loops at II and I2, there may be oneloop' extending from H to I2 as indicated iii Figs. 5 and 6. When the longitudinaledges 4 and 5 are rdlld together into a split tubularformation asshown in Fig. 3, an enclosure I3 is formed which may hold medicaments to be later released. This rolled corefits into the mouth of the ejector tube I4 which is provided with a reinforced lip I5.

A flat section of absorbent material I is woven through at points 9, III, II, and I2 with a draw string 6, 1, 8, as indicated. It may then .be impregnated with medicaments and its longitudinal edges rolled back towards each other until they are contiguous, forming an expansible, extrudable the ejector tube It to substantially full length 3 carrying the cords 1 and 8 looped back on themselves between the core and the tube. The cords 'l and 8 are then passed over the lip l5 and depend from it to have their free ends form the loop 6. When traction is applied to the loop 6 in a direction away from the lip l5, the core is slowly extruded from the ejector tube l4 until the guide loops II and I2 reach the mouth of the tube as in Fig. 2. The cords I and 8 then depend from points 9 and i through the guide loops H and I2 and down the outside of the tube. This poises the core at the mouth of the tube for proper positioning. Further traction on the loop 6 holds thebase 3 in position and unrolls and unfolds the expellable core by separating the edges 4 and 5 and straightening out the crown 2 into substantially a straight line, releasing any medication that may be in the enclosure I3. Still further traction pulls crown forward towards the base, the cords of the traction loop acting as draw strings through the guide loops. This practically everts or turns inside out the core as spread out, the edge 2 meeting the edge 3 horizontally with medication on the outside where formerly the edge 4 met the edge 5 vertically with medication on the inside. Tension is removed from traction loop and ejector tube is easily removed. The natural resilient action of the absorbent material now allows the base 3 retained up to this point in a circular formation by the mouth of the tube to expand towards a straight line further exposing the medicated surface. This entire mass may later be removed by means of traction on the loop 6, the curved corners of the crown facilitating removal.

It is apparent that the details of the device described may be varied without departing from the nature or principle of my invention and it is my intention not to limit the invention to the particular details set forth but to describe'one method of obtaining the desired end so that said end,being once realized, may be accomplished by changes in the construction and arrangement of the several parts, provided that such changes fall within the scope of the appended claims. 7
