Nov. 7, 1939. L. LORENIAN MEDICAMENT INTRODUCER Filed Nov. 18, 1936 Patented Nov. 7, 1939 MEDICAMENT INTRODUCER Libarid Lorenian, Bucharest, Rumania, assignor of one-half to Zareh Lorenian, Bucharest, Ru-

mania Application November 18, 1936, Serial No. 111,541 In Rumania November 25, 1935 2 Claims.

The object of the present invention is an appliance for introducing into. the vagina, the anus, etc., either liquid, more or less viscous or powdered medicines or capsules, pills, ovules or medicinal agglomerations.

According to the invention the appliance comprises a pump cylinder made of flexible material, such as paper, the material known under the trade name Cellophane, cardboard, Celluloid, rubber,

m or the like, impregnated or not, which makes it possible to close easily the front end of the cylinder by bending or contracting the edges of the walls themselves toward or into the cylinder axis until a complete closure is formed, which under the 15 thrust imparted by a piston upon the medicament, opens in order to clear the way for the contents of the cylinder.

Moreover, the invention provides that this cylinder may also be used as a receiver and packing 20 for the medicament by covering the closed front end or" the cylinder by a lid and by closing the rear end of the cylinder by a plug, lid and plug preferably being made of the same material as the cylinder, it being possible to use the plug as a piston and the lid as a rod for pushing this piston.

In the accompanying drawing, Figures 1 and 2 illustrate a preferred embodiment of the pump.

The edge of the front end of cylinder 9 is cut 30 over a certain length so as to have the shape of sawteeth 2 which are then bent toward the cylinder axis until they meet to provide the closure 3 so that under the pressure of the medicament these teeth can part to clear the 5 way for the medicament.

The front end of the cylinder closed in the described manner is covered by the lid 4 and the rear end is closed by plug 5. It is obvious that the latter may be used as a piston which must 40 be pushed by some rod.

From the above description it results that the described appliance of very simple "design and cheap material, supplied charged with the respective medicament, is intended to be used only once. The patient or the physician is no'longer obliged to carry out a cleansing, a sterilizing and 5 a charging operation after each use, i. e., he is no longer obliged to effect dimcult operations, which are necessary in case of an expensive instrument for repeated use.

What I claim is: l0

1. An appliance of the character described for introducing a medicament into a body cavity, said appliance comprising a cylindrical body of thin flexible material, one end of said cylindrical body consisting essentially of a plurality of 1011- gitudinally extending serrations with adjacent edges of successive serrations in contiguous relation to each other and with the vertexes of said serrations coinciding substantially with the longitudinal axis of said cylindrical body, whereby said serrations define an end closure for the latter.

2. An appliance of the character described for introducing a medicament into a body cavity, said appliance comprising a cylindrical body of thin flexible material, one end of said cylindrical body consisting essentially of a plurality of longitudinally extending serrations with adjacent edges of successive serrations in contiguous relation to each other and with the vertexes of 3 said serrations coinciding substantially with the longitudinal axis of said cylindrical body, whereby said serrations define an end closure for the latter, and a plug closing the other end of the cylindrical body, said plug being movable in said cylindrical body to displace medicament contained therein, said serrations being separable to open said first-mentioned end closure under the thrust of said plug, whereby said medicament may be discharged from said appliance.
