MEDICINAL APELICATOR AND DISPENSER James P. Robinson, Tokyo, Japan; vested in the Alien. Property Custodian Application April 14, 1941, Serial No. 388,441

4 Claims. 1

This invention relates to a medicinal applicator and dispenser, and has for its objects an improved device for applying a medicine in the form of a liquid or jelly, to internal body cavities for disinfecting such cavities and which device is flexible and elastic and is provided with a-socket for fitting over any suitable, relatively rigid projecture, for supporting the same in the desired body cavity during manipulation thereof, and which device also is formed with a supply chamber adapted to contain a supply of such liquid or jelly or the like,that communicates with a delivery or dispensing chamber, for supplying the contents of the supply chamber to the dispensing chamber for election from the latter at points where the said contents. will be spread by the walls of the device during manipulation of the latter.

Another object is a dispenser and. applicator of the above character having a tubular socket, the walls of which are adapted to be rolled up. to an apertured dispensing chamber at one end of the socket in which chamber the apertures; are. sealed by said walls when so rolled, preparatory to use of the device, and which walls are adapted to be unrolled to progressively enclose therein any suitably shaped supporting member, and when so unrolled for use of the device, the openings in the dispensing chamber will be uncovered for dispensing the contents of the chamber.

A still further object is a tubular socket provided with a closure at one end and a chamber outwardly of such closure having flexible walls with discharge apertures opening outwardly of the socket and chamber, and which walls are so formed as to carry a supply of antiseptic, medicine or the like, and to substantially control the delivery of such medicine from the supply chamber to the apertures for discharge from the latter.

Other objects and advantages will appear in the description and drawing.

Fig. 1 is a part sectional, part elevational View of my dispenser and applicator, partially broken in length.

Fig. 2 is an elevational view of my dispenser previous to use when sealed by the socket walls of the device.

In detail, my invention comprises a tubular socket member 1, open at one end and formed with a reinforcing ring 2 at said end.

The opposite end is closed by a concavo-con- Vex imperforate end wall 3, the concave side of which faces into the socket in member This end wall and walls 5 are preferably integral.

Over the convex outer side of Walls 3 is a cap with its concave side facing the convex outer side of end wall 3, but spaced from said end Wall, thus providing a chamber ii between said cap and end wall. Adjacent the connection 5 between the cap and socket member I, are one or more discharge apertures 1 that open generally radially outwardly of the central axis of the socket member 1 Preferably several of these openings are provided at equally spaced points around the margin of cap 4.

The cap 8 is centrally formed with bulbous chamber 8 projecting axially outwardly of cap 4;, and. which chamber 8 communicates with chamber ii-by a restricted passageway 9 that is coaxial with member I. A neck I!) may form the walls of said passageway, and also connect the walls of" chamber 6 with the walls of chamber 8.

These chambers 6, 8 may be filled with a germicidal, or antiseptic or medicinal liquid, or jelly H- through one of openings. 1, after which the walls of the socket member I are rolled on ring 2 from-- the open end of the socket member totively sealed, against leakage of the material H from the chamber 6 until the walls I rolled, as shown in Fig. 2.

The socket, being tubular and elastic, is adapted to receive therein, and to tightly embrace any suitable projecture, such as a finger, probe, etc, that is adapted to be inserted in a body cavity. The rolled up dispenser, as indicated in Fig. 2, is readily applied to such projecture by merely placing one end of the latter against the Wall 3 and unrolling the walls I or skirt portion of chamber 6, in the same manner as a rolled stocking is unrolled on the leg of a wearer. This unrolling of the walls I, uncovers the apertures I. and the device, supported on the support enclosed in the socket member, is ready for use.

In operation, when the supported applicator, ready for use, is inserted into any body cavity, tract, or opening, with the chamber 8 leading, it wil1 be seen that some of the contents of the are unchamber 6 will be ejected through opening 1 on the lining of such tract or cavity, but this ejection has been, many times heretofore, undesirably restricted by the lining itself, or the conbe ejected into chamber 6 through the restricted passageway 9, and from chamber 6 through apertures 1 to the desired area, upon reciprocation or manipulation of the applicator at, or adjacent said area, in a manner to create a pressure against the walls of chamber 8. If the ejection ofthe contents ll tends to be blocked by the lining of the body tract or cavity, then similar manipulation of the applicator will force the contents out of apertures l and into the cavity or tract. Thus, the chamber 8 is a supply chamber, while chamber 6 is a dispensing chamber from which the contents are ejected through apertures l, and the aperture 1 being in the margin of wall 4 close to the socket walls I and practically parallel with said walls I, it is manifest that the apertures 1 are sealed on opposite sides by wall I and by wall 3 when the ring 2 with walls I rolled therein cover apertures l, and there is no substantial pressure created on the contents enclosed in the dispensing end supply chambers.

The restricted neck 10 controls the passage of the contents of chamber 8 into the dispensing chamber 6, and in most instances, the chamber 8 will carry the contents thereof into a body cavity until the chamber 8 engages the end of such cavity, when said contents will be pumped, as it were, into chamber 6 and out of the discharge apertures I, thus insuring a dispensing of the material II at a point in the cavity remote from its opening.

Having described my invention, I claim:

1. A medicinal applicator and dispenser, comprising: a tubular socket member of relatively thin, flexible, and elastic material formed with an imperforate closure of the same material at one end and open at its opposite end for reception therein of a projecture; a dispensing chamber and a supply chamber for a medicament positioned outwardly of said closure on the axis of said socket member and adjacent said closure; a discharge aperture formed in the wall of said dispensing chamber and opening outwardly thereof, and a passageway communicating between said supply chamber and said dispensing chamber, the walls of said supply chamber and said dispensing chamber being relatively thin and flexible, whereby outside pressure on said supply chamber will force material therein through said passageway into said dispensing chamber for discharge from the aperture in the latter outwardly of said dispensing chamber and socket member.

2. In a construction as defined in claim 1, said closure forming one of the walls of said dispensing chamber, and said supply chamber bein at the side of the dispensing chamber opposite said closure and spaced axially outwardly of said socket member.

3. In a construction as defined in claim 1, the walls of said dispensing chamber and said supply chamber being integrally united, and the said supply chamber being generally of bulbous contour disposed on the axis of said tubular socket member spaced outwardly of said closure with said dispensing chamber disposed between said supply chamber and said socket member. I

i. In a construction as defined in claim 1, said socket member being formed with a ring con nected with its edges at said open end for rolling of the walls of said socket member thereon upon rolling the said ring on its annular axis toward said closure, and said aperture being positioned for closing by the rolled up walls of said tubular member when the walls of the tubular members are fully rolled on said ring, whereby the contents of said dispensing chamber and supply chamber will be sealed against leakage until said walls are unrolled and the device is ready for use.
