Specification of Letters Patent.

Application filed. May 5, 1908.

1 atentee Nov. 9, QOQ.

serian No. 430,939.

To all whom it may concern:

Be itI known that I, JOHN HOLTZMANN, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Instruments for Handling Semiplastic Substances, of which the following is a specification.v

This invention relates to an instrument or tool that may be used to inject into the rectum or other part of the human body a medicament such as ointment or a suppository. The instrument may be used for other purposes.

The object of the invention is to provide an improved instrument or tool that will irst abstract or remove from any mass of semi-plastic material a cylinder or sample of the material, and which will then place or deposit the said cylinder or sample wherever desired.

The invention comprises an outer tube, a piston within the outer tube that is stationar'y with respect thereto, and an inner tube that is movable telescopically with respect to both the outer tube and the piston.

The invention is illustrated in the accompanying drawing in which,-

Figure l is a perspective View of the improved instrument, showing the inner tube in the projected position. Fig. 2 is a longitudinal section of the several parts oit the instrument showing the inner tube in the projected position. Fig. 3 is a longitudinal section ot' the several parts of the instrument showing the inner tube in the retracted or telescoped position. Fig. i is a longitudinal sectional view on a larger scale of the end ot' the stationary piston.

The numeral, l, designates the outer tube having one end closed by a suitable cap or plug, 2, which may be confined or attached to the said tu'be by any suitable means that will permit of its removal when desired. The cap or plug preferably has a rim, 3, that is larger in diameter than the tube, and therefore forms a sort ot knob that may be conveniently grasped. The other end of the outer tube is open as at, et. In the present instance at its open end the outer tube is provided with a flat-surfaced ring-shaped flange, 5, which is rigidly attached. The outer tube also has a slot, 6, extending lengthwise of the tube.

A piston, 7, is within the outer tube and has a much smaller diameter than the bore or inner diameter of said outer tube, and is suitably secured by one end only so as to remain stationary with respect to the outer tube. In the present instance one end of the piston is secured to the cap or plug, 2; when, therefore, the cap or plug is removed, the piston also will be removed. An inner tube, 8, is open at both ends and is movable telescopically within the outer tube, and also slips over the tiXed piston; a pin or screw, 9, is attached to the inner tube and projects through the slot, G, in the outer tube, and on the exterior of the outer tube this pin or screw is attached to a suitable boss or enlargement, 10, that is convenient to be grasped by the thumb and inger ot the operator, so as to slide or move the inner tube. In the present instance what has been termed a boss or enlargement consists of a sleeve, l0, which surrounds the outer tube; the said pin or screw, 9, passes through the sleeve and the slot, 6, and into the inner tube, S. By grasping the sleeve, 10, with the thumb and iinger the inner tube, S, may readily be moved outward or inward relative to the outer tube.

The internal diameter ot the movable inner tube and the diameter orP the stationary piston, 7, are such that the piston will snugly but loosely tit within the inner tube, and the latter may slide over the said piston, 7, and inclose it like a sheath. The end of the pis ton has an elastic head or packing, ll, held in place by any suitable means, such as a screw, l2. This elastic head or packing` tits water-tight within the inner movable tube.

This instrument may be operated in several ways. T the ointment mass or material which is to be used is very soft, the inner tube, 8, should first be wholly within the outer tube, l; then by grasping the sleeve, l0, the inner tube may be moved outward a little, far enough for its projecting end to be inserted into the sott material, which latter may be in a bottle or other vessel,-the operator may then hold the inner tube stationary by one hand grasping the sleeve, l0, and with the other hand grasping the knob, 3, the outer tube and the piston, 7, may be moved so as to extend the two tubes; this movement will cause the piston, 7, to draw or suck the said sott material into the inner tube, as indicated at, 13. The tube now being charged with material should be inserted into the rectum, or other part that is to be treated, as illustrated in Fig. 2. Now the lil) desideratum is to LWithdraw the tube and at the same time to deposit or leave the ointment, 13, properly placed in the rectum. To do this, it is only necessary to keep the outer tube, 1, stationary and the collar or i'iange, 5, stationary against the entrance, and to move the inner tube, S, back Within the outer tube; in this back movement of the inner tube the head, 11, on the end of the stationary piston Will prevent the ointment, 13, withdrawing from the rectum, Which action is illustrated in Fig. 3, Where the tube, 8, is entirely back in the outer tube, 1, and the ointment, 13, has been left in the rectum.

The instrument is also adapted to be operated in a diiferent manner to suit material that is of a semi-plastic character, or stiffer than the soft ointment before referred to. rlhe stiersemi-plastic material would include such articles as tallow, Wax, cheese and paraiin. `When using the instrument with this stiffer material, the flat-surfaced ringshaped ange, 5, should be pressed against the mass of material, and the inner tube, S, then moved outward by pushing or sliding the sleeve, 10, which Will force the outer open end of said inner tube into the mass and as the tube enters the mass it Will cut a core, cylinder or sample of the mass which sample Will enter and fill the said inner tube, and then the tube may be Withdrawn, or removed from the mass, and the said sample Will remain charged Within the tube, 8; then by moving the said tube back Within the outer tube, the said core, cylinder or sample of the mass may be placed or deposited Wherever desired. In order to operate the instrument as last described, the open end of the tube, 8, should be thin and sharper' than when designed to be used the other Way which involves suction.

Having thus described my invention what I claim and desire to secure by Letters Patent is,-

In an instrument of the character described the combination of an outer slotted tube of uniform diameter' from end to end and provided at-its open end With a laterally-projecting flange and having a screwthreaded opposite end; a cap having threads to engage the screw-threaded end of said outer tube and said cap carrying a rod which projects through the outer tube and terminates adjacent the said iange thereon,-said rod being rigid with the cap; an intermediate tube of uniform diameter from one open end to the other open end and closely fitting the said rod, and a sleeve encircling the outer tube and carrying a projection that eX- tends through the slot of said outer tube and enters the Wall of the intermediate tube, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.
