Dt.22,1929. w. D. MCKENDRICK 3 66 POWDER INsuFFLA'roR Filed March 7, 1928 INVENTOR.
A TTORNEYS.
Patented Oct. 22, 1929 QFh'lE WILLIAM D. MCKENDRICK, OF SOUTH PASADENA, CALIFORNIA POWDER INSUFFLATOR Application filed March 7,
This invention relates to insufllators, and especially to an insull'lator whereby a dry powder or like substance may be introduced in the internal pz'issages or cavities of the body.
The object of the present invention is to generally improve and simplify the construction and operation of powder insutllators. To provide an insulllator which is adapted to be charged from a bulk supply with a dry pow- 10 der-like substance containing drugs, antiseptics, etc., and inserted in the internal passages or cavities where the powder is to be applied. To provide means for discharging and V uniformly distributing the powder by means of an air blast after insertion of the insufliator; and further to provide a syringe which may be readily and quickly charged and also taken apart for cleaning, etc.
The syringe is shown, by way of illustra- 20 tion, in the accompanying drawing, which shows a side elevation of the insufl'lator partially in section.
Referring to the drawing in detail, A indicates a tube constructed of metal. or like material. One end of the tube is designed to receive and retain a bulb 13 while the opposite end is slightly expanded to form a nozzlehead C. The nozzle-head is provided with an internally threaded section 3 to receive and support a nozzle such as indicated at 8. The nozzleliead is also provided with an internally threaded extension l, the exterior diameter of which is smaller than the interior diameter of the nozzle. Two or more openings 4t are formed at the base of the threaded extension t and these openings permit air to escape from the tube A into the annular space P formed between the exterior sur- 4O face of the extension 4 and the interior surface of the nozzle. The extension t forms a receptacle and a holder for a plug, generally indicated at 5, the plug being provided with a threaded extension 7 which is adapt- 45 ed to be screwed into the extension 4:. The outer end of the plug fits the interior diameter of the nozzle 8 and it is provided with one or more helical grooves such as indicated at 6, which serve the function of distributing the air discharging from the tube A into the anti l 1928. Serial No. 259,666.
nular passage 4". The forward end of the nozzle is provided with a discharge opening 9 but this is normally closed by means of a friction cap 10.
In operation the insulllator is charged as follows The nozzle 8 is first unscrewed and removed and the friction cap or closer 10 is applied. The nozzle is then filled with the disinfectant, or whatever-the case may be, in a powderlike form from a bulk supply, or otherwise, and it is replaced on the nozzle-head G by screwing is into the threaded extension 3. vl hen the syringe is to be used the friction cap 10 is removed and the nozzle is inserted in the internal passage or cavity to be treated. lVhen inserted the bulb B is depressed or squeezed by hand pressure and air will. thus be discharged through the tube A and the openings i into the annular passage 4h. The airthen escapes into the nozzle through the helical grooves 6. As the air discharges aroundv and through the helicalv passages it is evenly distributed within the nozzle 8 and as such discharges all the powder through the nozzle opening 9. The powder will. fur thermore discharge with a swirling-like movement and as such uniformly distributed and applied to the parts to be treated. The insrdilator may then be removed for recharging or cleaning, as the case may be.
The bulb B may be constructed in any suitable manner. That is, it is the usual type, provided with a valve 11 at one end. This valve closes when the bulb is squeezed or co1n pressed, thus discharging the air outwardly through the tube A. Conversely it opens and refills the bulb when the bulb is released and expands.
Any detail showing on the bulb and the valve mechanism employed is thought unnecessary, as a standard structure is employed.
While a more or less specific form of air distributing plug is illustrated, T wish it understood that the structure thereof may be considerably modified, as the object of the plug is that of retaining the powder; that is, preventing it from working rearwardly or downwardly through the tube, and that of uniformly delivering or distributing the air line so'that complete discharge of the powder will take place when the bulb is squeezed;'and while other features of the invention are more or less specifically described and illustrated, I Wish it understood that. changes may be resorted to within the scope of the appended claims. Similarly, that the materials and finish in the several parts employed may be such as the judgment of the manufacturer may dictate or varying conditions or uses may demand.
I claim 7 1. In a powder insulilator, a nozzle-head, a nozzle detachable with relation thereto, a tubular extension within the nozzle-head, a plug detachable with relation thereto and substantially fitting the interior of the nozzle, said tubular extension having an exterior diameter smaller than the interior diameter of the nozzle to form an annular air receiving passage, said tubular extension having openings formed therein in communication with a source of air supply, and a plurality of helical shaped ribs formed on the exterior of the plug to impart a swirling motion to air discharging from the annular passage.
2. In a powder insufflator, a nozzle-head, a nozzle detachable with relation thereto, a tubular extension within the nozzle-head, a plug detachable with relation thereto and substan tially fitting the interior of the nozzle, said tubular extension having an exterior diam' eter smaller than the interior diameter of the nozzle to form an annular air receiving passage, said tubular extension having openings formed therein in communication with a source of air supply, a plurality of helical shaped ribs formed on the exterior of the plug to impart a swirling motion to air discharging from the annular passage, and a friction cap removable with relation to the nozzle.
