ATTORNEYS Patented Aug. 12, 1947 APPLICATOR Stephen Malko, Chicago, Ill., assigner to Malko & Lock Machine Products, Chicago, Ill., a partnership composed of Stephen Malko and John A. Lock Application November 12, 1946, Serial No. 709,143

(Cl. 12S-185) 3 Claims.

This invention relates to improvements in pressure applicators for medicaments or the like and more particularly to nasal syringes with which medicated air may be forced into the nasal passages and sinuses.

lIhe heretofore used syringes, nasal douches, etc., as a general rule, directed a liquid into the nasal passages. This process was generally undesirable and unsuccessful as the nasal passages, when affected by hay fever, colds, and sinus infections were at least partly filled with a fluid or mucous which prevented the effective induction of any additional fluid. Because of this dificulty, it was desirable to induce medicated air into the affected channels. Induction of the air was usually accomplished by having the person so affected breathe or inh'ale the medicated air. Inhalation of medicated air proved undesirable as it was almost always impossible (due to the cold, etc.) to induct enough air into the affected channels to be effective. `It was to overcome these and other obvious defects that the present invention was conceived.

The main objects of this invention are to provide a device of this character adapted to size and form, to be held in the hand and having one end thereof partially insertable into a nostril; to provide a device of this character which when operated manually will force medicated air into the sinus and nasal passages; to provide a device of this character which is manually operated by means of a piston; to provide a device of this character having an absorbent material inthe discharge end capable of being saturated with a medicament and which is readily replaceable and removable; to provide a device of this character compact enough to be carried in a vest pocket or other small compartment; to provide a device of this character which is easily sterilized; and to provide a device of this character which is relatively inexpensive and simple to manufacture.

An illustrative embodiment of this invention is shown in the accompanying drawings in which:

Figure 1 is a side elevational view of the invention.

Fig. 2 is a cross-sectional view taken on line 2-2 of Fig. 1.

Fig. 3 is a top view of the device.

Fig. 4 is a bottom view thereof.

Fig. 5 is a sectional View taken on line 5-5 of Fig. 2.

Referring in detail to the drawings, the applicator which is preferably constructed of chromeplated metal parts, comprises a cylindrical bar- 2 rel or body I, the ends 2 and 3 of which are both open and are provided with internal threads.

Piston 4 iits snugly within the body i and is adapted to be reciprocated therein. The piston is pro-- vided with an axially threaded bore 5 in the lower end thereof for the reception of a plunger which is adapted to seat in the bore 5 axially. The rod t is held axially in said housing by a guide bushing 8 which is threaded into the lower end 2 of the body I. The bushing 8 is also provided with knurling 9 whereby to facilitate removal thereof when desired.

The body I is also provided with a hollow cap @il having external threads II thereon adapted to be secured to the end 3. The cap ill is provided with large axial bore or chamber iI.I in the lower end thereof and a smaller internally threaded axial aperture l2 in the upper end thereof communicating with the bore II.I. The finger gripping'means comprises a washer-like disc i3 which is adapted to loosely seat in an annular groove I4 located in the cap Ill, and a pair of bent arms I5 and i6 integrally formed on said disc I3 and each positioned laterally of said disc on opposite edge thereof.

A ne wire mesh screen Il substantially equal in diameter to the inside diameter of the barrel l is adapted to fit snugly within the body I and is kepfi-l in tight abutment against the lower end of the cap I0 by one end of a coil spring i8. The opposite end of the spring I8 abuts against and seats on the upper end of the piston l whereby When the piston is forced inwardly (or upwardly as viewed in Fig. 2) the spring IS will cause the piston to return to the position shown in Fig. 2.

A domed-shape snout or nozzle I9 is provided with an externally threaded neck 20, which neck 20 is smaller in diameter than the main body of the nozzle i9 whereby to form a seat 20A which is adapted to abut against the upper surface of cap I0 when threaded into the aperturel I2 of the cap ID. A relatively large axial bore or chamber 2| extends substantially throughout the length of the nozzle I9 and communicates with the atmosphere through a relatively small air passageway '22, axially positioned in the top or dome end of the nozzle I9.

An absorbent material such as cotton, or the like, 23, saturated with a liquid inhalant, medicament, or the like, is placed in the chamber II.I. Although I have shown saturated cotton as the preferred embodiment of my invention, it is to be understood that any medicament in solid or brick form may be used so long as the solid medicament has an air passage or vent therein, whereby air pressure developed in the upper end of the housing I by reciprocation of the piston 4 can readily pass therethrough or therearound and pass into the chamber 2l and out through' the passage 22.

In operation the cap I@ is removed from the housing I and cotton 23 saturated with a medicament is placed in the chamber I I.I of the cap I0. The cap is then replaced on the housing I. The free end f the nozzle I9 is then inserted into one nostril and held in position by means of the finger grips. The piston 4 will, due to the action of the coil spring I8, be in the position shown in Fig. 2. The piston rod 6 is then quickly forced upwardly by the users thumb thereby moving the piston 4 upwardly causing the air in the housing I to become under pressure due to therestricted outlet opening 22. The air under pressure passes through the wirerscreen Il' and into the chamber I I .I through the saturated cotton 23 contained therein, into the chamber 2l and out through the passageway 22. The air forced past the cotton 23 picks up fumes only from the medicated cotton and thus medicated air is forced into the nasal passages. It is to be distinctly understood that medicated air only, andA not a mist, or a uid, is forced into the nasal passages by the use of the device of this invention.

1t 1s to be understood that numerous details of this invention may be altered or omitted Without departing from the spirit of this invention'as defined by the following claims.
