Claim 1
Independent Claim
284 words
A medical apparatus for inserting medications and/or hygienic preparations into body openings and/or cavities without the use of an additional hand or fingers, said apparatus comprising: a. a hollow cylindrical handle having a first longitudinal section positioned toward its front end and a second longitudinal section adjacent to said first section and positioned toward its back end; b. a replaceable tubular insertiOn nozzle inserted in the front end of said hollow handle, said nozzle being adapted to have medications placed in its front end, said tubular nozzle having a stop ledge at its rear end and a central opening surrounded by an annular stop ledge and a ram positioned in its rear portion with the front end of the ram in the central opening and adhering to the annular ledge, said ram having a sealing plate on its rear end; c. a piston slidably mounted within a longitudinal guide within said hollow cylindrical handle in which said guide is longitudinally displaced, the upper side of said piston being formed as a rack and said piston having a collar engaging with the opposite ends of said guide to limit the movement of said piston relative to said guide; and d. a knurled wheel rotatably mounted in said hollow handle with a portion thereof extended outside of said hollow handle, said wheel engaging with the upper side of said piston whereby the counterclockwise rotation of the knurled wheel pushes the piston forward past the first longitudinal section against the sealing plate of the ram to move the ram forward through the center opening and the plate forward in adherence to the annular ledge, thereby pushing out the medication from the front end of the insertion nozzle.

284 words
A medical apparatus for inserting medications and/or hygienic preparations into body openings and/or cavities without the use of an additional hand or fingers, said apparatus comprising: a. a hollow cylindrical handle having a first longitudinal section positioned toward its front end and a second longitudinal section adjacent to said first section and positioned toward its back end; b. a replaceable tubular insertiOn nozzle inserted in the front end of said hollow handle, said nozzle being adapted to have medications placed in its front end, said tubular nozzle having a stop ledge at its rear end and a central opening surrounded by an annular stop ledge and a ram positioned in its rear portion with the front end of the ram in the central opening and adhering to the annular ledge, said ram having a sealing plate on its rear end; c. a piston slidably mounted within a longitudinal guide within said hollow cylindrical handle in which said guide is longitudinally displaced, the upper side of said piston being formed as a rack and said piston having a collar engaging with the opposite ends of said guide to limit the movement of said piston relative to said guide; and d. a knurled wheel rotatably mounted in said hollow handle with a portion thereof extended outside of said hollow handle, said wheel engaging with the upper side of said piston whereby the counterclockwise rotation of the knurled wheel pushes the piston forward past the first longitudinal section against the sealing plate of the ram to move the ram forward through the center opening and the plate forward in adherence to the annular ledge, thereby pushing out the medication from the front end of the insertion nozzle.
Claim 3
Dependent Claim
66 words
A medical apparatus according to claim 1, wherein the knurled wheel is rotated further to push the piston forward past at least part of the second longitudinal section whereby the collar of the piston engages the front end of said longitudinal guide to move the guide forward with sufficient force against the rear stop ledge of said nozzle to expel the nozzle from the hollow handle.
Claim 4
Dependent Claim
28 words
A medical apparatus according to claim 1, wherein the ram of said nozzle has a length corresponding to that of said first longitudinal section of said hollow handle.
Claim 5
Dependent Claim
44 words
A medical apparatus according to claim 1, wherein the longitudinal guide comprises two bars extending parallel to the piston, a disk mounted on its front end having a hole for the passage of said piston, and a corresponding semi-disk mounted on its rear end.
Claim 6
Dependent Claim
36 words
A medical apparatus according to claim 4, wherein the collar on said piston is arranged on the bottom side thereof in the form of a knob coacting with the disk and semi-disk of said longitudinal guide.
Claim 7
Dependent Claim
20 words
A medical apparatus according to claim 5, wherein the annular stop ledge comprises a sealing lip adhering to the ram.
Claim 8
Dependent Claim
46 words
A medical apparatus according to claim 1, wherein the insertion nozzle on its outer surface has an annular groove engaging therein an annular bead positioned on the front end of the hollow handle and the longitudinal guide is arranged to move only in the second position.
Claim 9
Dependent Claim
72 words
A medical apparatus according to claim 7, wherein a screening disk is positioned on said nozzle in front of said annular groove, said disk comprising reinforcement ribs and a foldable skin extending between the reinforcement ribs, said ribs being arranged on said nozzle such that when the insertion nozzle is placed on the hollow handle the ribs are spread apart by the annular ledge to form with the skin a screen-like structure.
Claim 10
Dependent Claim
19 words
A medical apparatus according to claim 8, wherein the screen-like disk can be placed separately on the insertion nozzle.
Claim 11
Dependent Claim
43 words
A medical apparatus according to claim 7, wherein the insertion nozzle is provided with an inner annular lip in the area corresponding with said outer annular groove, whereby the lip slides on the piston as the nozzle is being expelled from the apparatus.
Claim 12
Dependent Claim
22 words
A medical apparatus according to claim 1, whereby the tubular insertion nozzle has apertures spaced in the side of its tubular part.
