NASAL SUCTION-PUMP.

Specification of Letters Patent.

Patented Apr. 2, 1918.

Application filed April 29, 1916. Serial No. 94,352.

To all whom 'it may concern.'

Be it known that T, FRANK W. PETERSON, a citizen of the United States, residing at Minneapolis, in the count-y of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Nasal Suction-Pumps, of which the following is a specification.

My invention relates to nasal suction pumps used for withdrawing the discharge from the nose when the patientis unable to perform this duty in theV natural manner on. cold in the head and other similar aftlictions, and has for an object to provide a stiff bulb attached to a suction head capable ot' being inserted into the nostril. A further object is to form the suction head with a countersunk opening which will in all positions remain remote from the mucous membrane within the nostril and so not cause any pain or irritation to the patient through improper' application of the device. A further object is to provide the bulb with a large opening communicating with the suction head, to permit the easy cleaning of the device. A further object is to form the bulb with thickened walls to cause the same to be more stii and have a positive action.

The full objects and advantages of my invention will appear in connection with the detailed description thereof and are particularly pointed out in the claims.

In the drawings, illustratingthe application of my invention m one form,-

Figure 1 is a. longitudinal sectional view of a suction pump embodying my improvements. Fig. 2 is a view similar to Fig. 1 of a modified form of pump. Fig. 3 is a view similar to Fig. 1 ot a still different form of suction pump.

My preferred form of pump is clearly shown in Fig. 1. A spherical bulb 10 is provided having thick walls 11 formed of stiii rubber which, when distorted, will quickly return to its original position. The top of the bulb at 12 is formed with internal threads 35 to receive a glass, hard rubber or metal neck 13 which is provided with an enlarged sleeve portion 14 having a {iange member 15 and corresponding threads 16 engaging the bulb portion 12 as clearly indi-` cated in the drawings. By this means the bulb 10 can easily be removed or attached to the stem to facilitate cleaning. In view of the said last-named project the opening into the bulb 10 through the portion 12 is made large enough so that a persons finger or a suitable brush may be inserted into the bulb through the aperture. The stem 13 is preferably formed narrow and short and terminates in a substantially spherical head 17 somewhat larger in diameter than the nostril to which it is to be applied. This head is provided with an aperture 18 the walls 19 of which are sunk into the spherical head 17 to form a countersunk opening into said device. The sides 2O oi bulb 10 are formed thicker than the remainder of the wall 11, so that as the bulb is pressed upward the same tends to quickly and eliectively return to its original position causing a positive action in the device. The lower portion 21 of the bulb may be made flat on the bottom thereot` so that the device will easily stand on end.

The method of using the device is as follows: The bulb 10 is distorted or collapsed in the usual manner by pressing the bottom 21 inward with the thumb. One nostril is then closed by a finger of the other hand and the spherical head 17 inserted into the open nostril. It is not intended, however, that head 17 be positioned entirely within the nostril as suction would hence only cause the device to be drawn farther into it. By swallowing` or by pronouncing certain letters the valve communicating between the nasal passages and the mouth can be made to close, and when such a condition is procured the bulb 10 is released. This causes a vacuum in the nasal passages which draws out the discharges from the glands in said passages into the bulb 10, completely removing the same without effort on the part of the patient. 1n cases where such a device is used the mucous membrane is usually sore and tender. It the opening in thehead 17 could be placed directly in contact with any portion of the mucous membrane, the same would tend to be drawn into the head, which would eiiect severe pain and discomfort. With the countersunk opening such a condition is entirely eliminated since the device would have to be at right angles to the surface.

A modiiied form of pump is shown in Fig. 2. A bulb 21 quite similar to bulb 10 is here used, which is provided with a portion 22 similar to portion 12 of bulb 10. This portion is similarly formed with internal threads 23 which engage corresponding eX,-y

terna-l threads 24 on a receiver member 25. Member 25 is provided at one endwith a head 26 identical with head 17 and is formed with a pocket or depression at 27 in which the discharge is collected. The device is applied to the nostril in an inclined position instead of vertically, as in the case of the device shown in Fig. 1. In this manner the discharge is deposited in pocket 27 instead of into the bulb 21.

A still diierent forni of pump is shown in Fig. 3. A bulb 28 identical with bulb 10 is employed, to which is secured a stem ineinber 29 adapted to be engaged and held inV place. in said bulb similarly to the stem 13 shown in Fig. 1. This stem is quite short and termlnatesin a portion 30 adapted to lbe inserted into a Flexible rubber tube 31.

Tube 31 is Vattachedat its other end to a stem portion 32 similar to portion .30, which terininatesin a spherical head 33v identical with head1?. This device-diners only from that shown in Fig. 1 `in that the head is flexibly connected to fthe bulb.

The advantages of my invention are manifest.V The4 device is very simpleand easy to operate.` t is practicably impossible to tilt the head so that the mucous membrane. is drawn into the same to cause dlscomfort.

neeneoe The ease with which the device may be Y cleaned and'thefew'ness.ofiI the parts render it quite sanitary.

I claim:

1. A nasal suction pump comprising a suction bulb, and a suction head secured' thereto and in communication therewith, said head having a counter sunk aperture 1n the end thereof fondrawing inv the dis-- secretions, said suction head being constrnctedand shaped to t into the nostrilofy a person.`

In testimony whereorl l affix my signature in presence of two witnesses.
