INVENTOR u dum! @L ATTORNEY Aug.' 19, 1930.r E. BucHwALD DEVICE FOR THE INTRODUCTION, IMMERSION, AND SPERSION 0F MEDICAMENTS Filed March 29. 1929 Patented Aug. 1%, i930 EMILIO BUoIIwALnoE Bri-Enos III-EES, 'aEGENTINa Application mean/Laren aa'iaesfseriai Nq. 350,880.`

The present invention refers to a new de-` vice for clinical use for the introduction, immersion and aspersion of medicaments in the form of powder, pomade, liquid, etc., in any 5 internal part of the body, the employment of which represents distinct advantages of a practical order, inasmuch as its low cost and simplicity makes it` an instrument within the reach of everybody, apart from which it is of positive results.

In order that my application may be more comprehensible, I have illustrated same with various figures, wherein:

the device.

' Fig. 2 is a longitudinal sectional view ot a variation of same. Y

Fig. 3 is a view of one ot the rods, forming a complement of the device.

Construction The construction comprises a depository with walls ot glass (a) and bases of metal.

(), into which is introduced the medicinal substance, either in the form of powder, pomade, liquid, or any other. In its lower part is found a nozzle (c) to which is attached the end of a rubber tube (d) pertaining to a bulb of the same material. In this drum or deposit (a) (b), is inserted a canula (e), which may be straight, partially or totally curved, and its end may be acute, obtuse, or intundibulitorm, according to the nature and object; said canula may have or not the division (7) which divides it in two (Fig. l), or it may be simple asv shown in Fig. 2, the diameter and length varying according to circumstances, and moreover, the canulas may have holes in their sides, in order that the introduction ot the medicament may not only be effected by the end of same, but also laterally.

The canulas (e) and (e) and lany other which may be manufactured, are always part and complement of the drum (a) (b), which may be constructed in accordance with Fig. l, that is, following the line of the canula (e), orftorming a right angle with same, or in any other convenient manner.

The canula (e), Fig. 2, free of internal Fig. 1 is a longitudinal sectional view ot' division, has-as a propellant of the med-icament, aspiral (g'),'thread, spring, or rod, ,whichpushes or works in such a manner, that iteiiects the introduction of the medicament. y l 4.' As will be .'Se.en-, fthe various Qcanulas (e) '55 (ef), which m'ay'be conceived, areinter'- chan'gcable, and that which is'considered Ythe ,i/nist'nvenient may be placed in thefdrum -`-`,I`he rods (j). (le), Fig. 3, arev complements of 'tlie'device,`the object .of which' will be explained," and may beQ-of rigid or flexible material', otone sole 'piece' (Ic) or divided oradopt the most convenient` form. The di- Y ameter and length kof said rods may vary yaccording to the special Y'casesinwhich they are employed.` .y i

c fwofeagf The devicevf works as `follows:

On the canula (c) (e) being introduced it is necessary to avoid that the pus or liquid matter of the body, by automatic effect, may ascend bythe canula and obstruct or embarrass its working, and for this object I insert in the interior ot the canula (e) (e), the rod most adapted, be such or (la), rigid or iiexible according to the case. The same is later withdrawn, to then eliect the introduction of the medicament. If it is desired to use the canula (e), the bulb (cl) will be employed in order that the medicament in the form of powder which is generally found in the drum (a) (b) may be pushed in a forward direction, being introduced by I the aperture (7L) and deposited in the part of the body which has been reached by the canula. The air which has served to draw the medicament does not remain, nor is it lodged, f.

as happens with the usual apparatus, but returns by the other higher half of the canula (e), Fig. l, wherein the arrows indicate the passage of air, the latter being obturated in the lower part by the wedge (Z), which is removable.

IVhen it is not desired to employ air as the propellant, the thread or spiral (g) will be used, (Fig. 2), which in turn may be varied as to form, and it may take that of a simple rod, spring, piston, etc., without this repre- F- senting a departure from the sphere of the invention, the principal features of which are the method of propulsion with the deposit of the medicament, and the interchangeability of the various canulas.

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

1. In a device as described, a glass depository for the reception of a medicament, perforated metal caps for said depository, a tube passing through the perforations of said caps and said depository, said tube having a plurality of openings formed in its Wall and an aperture Within said depository, a longitudinally extending partition dividing said tube, anda means for expelling the medicament contained in said depository into a body.

2. In a device as described, a glass ldrum Afor the reception of the medicament, metal caps closing the ends of said drum and having central openings, a perforated tube extending through the openings in said caps and the drum, having a feed opening Within said d rum, a longitudinally extending partition in saidtube, a nozzle formed With one of said caps adapted for engagement by a rubber. tube, and a bulb at the end of said rubber tube for expelling the medicament in said drum into the cavities of a body, and means for elosin one end of said perforated tube, said tube adapted for the reception of means preventing its obstruction.

In testimony whereof, Ialix my signature.

i EMILIO BUGHWALD.
