PETER THORHAUG, OF MINNEAIOLIS, MINNESOTA.

EMBALMING- INSTRUMENT.

Application filed May 16,

To a?! /1/1 710m it may concern Be it known that I. PETER THonrL-ino, a citizen of the United States, residing at Minneapolis. in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Embalm ing Instruments; and I do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in embalming instruments and more particularly to devices for injecting blood solvent into the veins and for draining the blood therefrom. Heretofore, in a great majority of cases, separate operations have been necessary to first inject the blood solvent into the veins and to then drain the blood and solvent therefrom, it being often necessary to repeat these operations several times before the required results are obtained. This is not only arduous and requires a great deal of time, but there is danger of soiling articles around the corpse, as well as otherwise adding greatly to the duration of the embalming operation.

One object of my invention is to provide a simple, inexpensive and easily operated device by whose use. the blood solvent may be injected into the veins and the blood drained therefrom at the same time, novel provision being made however whereby the blood outlet may be totally or partially closed whenever it is desired to withdraw a greater or less amount of the blood.

In carrying out the above end, I pass a solvent-injecting tube slidably through a drainage tube and a further aim is to make provision for projecting saidy solvent-injecting tube a considerable distance from said drainage tube, whereby the solvent may be forced a greater distance into the veins than is possible with the instruments now in common use.

With the foregoing and minor objects in view. the invention resides in the novel construction vand association of parts herein! after described and claimed, the descriptive matter being supplemented by the accompanying drawing:

Figure l is a side elevation of an embalming instrument constructed in accordance with my invention.

tional view through'the greater part of the Y device.

Figure 3 is a transverse see-tional View as indicated by line 3-3 of Fig. 2.

Figure 4 is an enlarged detail sectional view through the drainage tube, showing an elevation of the solvent-injecting tube and its tip.

Figure 5 is a view similar to a portion of Fig. 2 but illustrating the manner in which the blood outlet may be closed whenever desired.

In the drawing above briefly described,v

the numeral l designates a tubularv drainage tube formed of rear and front'sections 2 and 3 respectively, said rear section being preferably of somewhat larger diameter than the front section in order to form a handle which may be more conveniently used than if it were offsmaller size. The section 3 may be straight or curved as occasion may dictate and this section is preferably detachably connected with the rear section 2, for instance by screw-threads 4, so that whenever necessaryy a shorter or tube, the front section 9 of said tube being t preferably of much smaller diameter than the rear section, since it must bef projected into the vein. y The two Vsections- 8 and 9 are detachably connected with each other by any suitable means such as the screw-threads 10 shown in Figs'2 and 5. The rear section 8 serves asrmeans for projecting the front end of the Section5) to the necessary extent beyond the front endof the tube section 3, or for withdrawing said section 9 within the section 3 as seen in Fig. 4 so as `to facilitate insertion of the entire device into a vein. lIn order to prevent clogging of lthe'tube 1 as it is being forced into the vein, the front terminal of the tube section 9 is provided with a plug 11 which then closes the front end of the tube section 3 as seen clearly in Fig. 4. The rear end of the tube section ,8 is adapted for connection with a rubber tube leading from a receptacle containing the blood solvent or other liquid to be injected into the vein, while the front end of said tube section is provided with a valve piston 12 which is adapted to control the outlet branch 5.

When operating the device, the inner tube 8 9 is pulled outwardly to the extent shown in Fig. l, thereby positioning the plug 1l in the front end of the tube l to prevent congealed blood or fibrous tissues from clogging the front end* of the device. Then the tube section 3 has been inserted the proper e tent,vthe supply of solvent liquid is forced through the inner tube and the latter may be forced inwardly to any required extent beyond `the front end of the tube section 3, The `congealed blood is thus dissolved and will How through the tube l and its branch 5 to the receptacle provided for its reception. If it is desired to continue the injection of solvent while temporarily lessening the discharge of blood, the tube section 8 is forced inwardly to the extent shown in Fig. 5 whereby the valve l2 will close the branch 5. Furthermore, by proper manipulation, the branch may be opened `to any desired extent so that the ratio ofthe ingoing liquid to the outgoingblood, may be controlled to produce the most advantageous results.

I After use, the device may be quickly and easily disassembled for cleaning,due to the screwthreaded connections 4 and 10 and tbe threaded gland' which receives the tube section 2. It is to be Vfurther noted that by employingthe threaded connections 4 and 10, tube sectionsV 3 and 5 of differentdiameters o1' lengths may be provided, so that the device may be perfectly adapted to the operation to be performed. Attention may also be directed to the fact that by tightening the glandt, the packing ring 7 is forced to hold the rear tube section 8 in any position to which itinay be adjusted, this being often of great advantage since the operator does not thenhave to hold said tube section with one hand.`

'From the foregoing taken in connection with the accompanying drawing, it will be seen kthat whilemy invention is very simple and inexpensive, 1t will vbe highly efficient and in every "way ldesirable, permitting simultaneous in'ection of blood solvent and draining of b ood, Without "any danger ot' soiling the clothing or any articles around the corpse.

Sneeexcellent results have been obtained from the exact fdetails disclosed, they are preferably followed." Itis to be understood however that within the scope o'lr the in 'vention as claimed, numerous minor changesl may be made and 'furthermore that the device may be constructed in its entirety at the factory, or provision may be made for converting the draining tubes now on the market, into the improved device.`

I claim:

l. A. solvent injecting and vein draining device comprising a tubular body having a stuling box at its rear end and a lateral outlet, said body being provided with an outer forwardly extending tubular needle o'l' uniform diameter throughout its length and adapted to be inserted in a vein of a corpse, an inner tubular needle slidable within said first named needle and having a rear end portion passing through said stufiing box,

the portion of said inner needle received in said outer needle being of less external diameter than the internal diameter ot the latter and being adapted to be projected forwardly from sai-d irst named. needle to vsupply blood solvent tothe vein while draining blood from the latter through vthe outer needle.

2. A. solvent'injecting and blood draining device comprising a tubular body having a stuffing box at its rear end and a lateral outlet, said body being provided with an outer forwardly extending tubular needle longitudinally curved and of uniform diameter -throughout its length Yfor insertion into a vein of a corpse, a rigid tubular body-slidable. through said ustuliing box, and an inner resilient needle extending forwardly from said rigid body through said outer needle vin spaced relation thereto, said inner needle being adapted to be projected forwardly from said outerneedle to inject blood `solvent into the vein while draining blood from the latterthrough the Vouter needle.

3. A solvent injecting and blood draining `device comprising a rigid tubular handle having astuiing box at its rear end and a lateral. outlet near its lront end, a rigidtube section slidable through said stuifling box, au outer tubular'needle threaded-in and eX- tending forwardly'from said handle, and an inner tubular needle within and spa-ced 'from said outer needle, said inner needle being threaded at its rear end into said tube section, said inner needle being adapted' to be projected forwardly from said outer needle to inject blood solvent into the `vein -while drainingblood from the latter through the.

outer needle. i In testimony whereof I have hereunto set my hand.'
