Abstract

A nasal filter has a pair of members fitting in the nostrils, each member having a central air intake passage with a screen between the front end of the passage and the ambient air. The central passage is surrounded by an annular exhaust channel closed by a one way valve allowing exhaled breath out. A slidable closure plate closes the back end of the air intake passage during exhaling to avoid mixing fresh and vitiated air, the plate being pushed against the end of the channel by the pressure of the exhaled air. An electronic filter powered by a battery to which both members are attached is positioned in the central passage for holding dirt or other particles which may pass through the screen.

Field of the Invention This invention is concerned with a filtering device for insertion in the nostrils to prevent foreign particles from entering the nasal passages by excluding physically the greater part of such particles and'the rest by electrostatic precipitation.

Nasal filters are being used more in industry and by inhabitants of cities where the air quality is unacceptable. Heretofore such filters depended on physical means only to exclude foreign matter and were not completely successful in so doing. Some of the filters proposed are uncomfortable to wear. Others do not effectively prevent mixing air being inhaled from vitiated air being exhaled.

2. State of the Art The art to which this invention relates already is aware. inter alia, of the devices described in U.S. Pat. Nos: 2,526,586; 2,535,155; 2,890,695 and 3,457,917. The filters described in these patents do not include electrostatic precipitating means.

SUMMARY OF THE INVENTION The principal object of this invention is to provide a device or article of this character which combines simplicity, strength and durability in a high degree, together with inexpensiveness of construction.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts which will be exemplified in the construction hereinafter described, and of which the scope of application will be indicated in the following claims.

BRIEF DESCRIPTION OF THE DRAWINGS In the accompanying drawing, in which is shown one of the various possible illustrative embodiments of this invention, wherein like reference character identify the same or like parts:

FIG. 1 is an elevational view of a filter of the invention shown in place within the nose of a wearer and showing the filter during exhalation;

FIG. 2 is the same as FIG. 1 for the inhalation cycle;

FIG. 3 is a cross-sectional side view of one filter unit;

FIG. 4 is a top plan view of one of the electrostatic precipitator;

FIG. 5 is a cross-section through line 5-5 of FIG. 3 showing details of the air shafts and canals;

FIG. 6 is a detailed cross-sectional view of the one way valve in the air canals of FIGS. 3 and 5 shown open during exhaling; and

FIG. 7 is the same showing the valve closed.

With reference to the drawing, there is shown and illustrated a nasal filter constructed in accordance with the principles of the invention and designated generally by reference character 10.

As shown in FIGS. 1 and 2, the filter comprises an insertable unit for each nostril. The unit is illustrated in detail in FIG. 3. The filter unit comprises a body 12 shaped to conform generally to the contour of the nasal passage and made of easily moldable plastic such as polyethylene, polystyrene, polypropylene bakelite or of hard rubber. To fit better in the nasal passage, body 12 is surrounded by a coating of liquid or petroleum jelly 14 covered by a thin flexible membrane 16 of polyvinyl chloride or polyethylene fused to the crimped end of body 12 as at 17 and 18 (FIG. 3). An inner plastic elongated member 20 with its sidewalls generally parallel to body 12 is connected thereto by a plurality of spaced ribs 22, 24, 26. Member 20 forms the air intake passage for the filter as indicated by the six arrows in FIG. 3.

At the outer end of member 20 is removably mounted a disc filter 28 of well known construction, such as for example, but not by way of limitation, a mesh metallic gauze having a plurality of closely packed openings. This filter prevents particulate foreign matter from entering the nasal passages of the wearer. Preferably, the disc is force-fitted at the extremity of member 20 so that it may be removed for cleaning. Interposed within member 20 is a precipitator screens 30 (FIG. 4). The top screen of which is connected by wire 32 to the positive side of battery 34 and the bottom screen of which is connected to the negative pole by wire 33. The wires leading from the battery 34 to the two bodies 10 can serve also to keep these together in the manner of a clip. A micro-switch 36 is provided on the battery since the same is intended to be turned on only when the ambient air is highly polluted.

As shown in FIG. 3, a cylinder 38 is formed at the inner end of member 20 and is secured thereto at its outer end by radial ribs 40 (FIG. 5). Cylinder 38 is formed with an upper stop 42 and lower stop 44 for limiting the course of plunger 46 in its axial bore. Rod 48 connects plunger-46 to flat closure 50 so as to close the peripheral air passage 52 between the outside of cylinder 38 and the inner section or wall of member 20 during exhaling (FIG. 1). Plunger 46 preferably should be of self-lubricating plastic such as teflon in order to slide easily in response to inhaling (FIG. 2) and exhaling stages. During the latter stage, no exhaled substances (mainly CO N, and H 0) pass through body 20 but instead through air canal 54 between the outer surface of body 20 and the inner surface of body 12. Air canal 54 has a one way valve 56 which opens upon application of exhaling pressure as shown in FIG. 6 but remains closed during inhaling as shown in FIG. 7.

This filter is especially useful in alleviating the symptoms associated with hay fever and is also adapted for use by persons in areas where various foreign substances are present in the air which might cause discomfort or even occupational diseases.

The operation and use of the invention hereinabove described will be evident to those skilled in the art to which it relates from a consideration of the foregoing.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is Well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.

Having thus described the invention, what is claimed as new is:

l. A nasal filter comprising a pair of insertable members shaped to conform to the shape of nasal passages; each member including: a central air intake passage ex- 2. The filter of claim 1 wherein said insertable members have an outer coating of flexible plastic.
