To all whom it Truly concern: I
Be it known that I, ALBERT O. HEATH, a citizen of'the United States, residin at St. Paul, in the county of Ramsey and tate of Minnesota, have inventedcertain new and useful Improvements in Medical Appliances, of which the following is a specification,
This invention relates to certain new and useful improvements in medical ap liances, and has reference more particulary to an, improved device for the treatment ofhay fever, and other similar ailments. V The invention has forits object the production of a simple and inexpensive device which can be inserted into the nostrils for the purpose of filtering the air'drawn therein'to in breathing, whereby, injurious substances are prevented from coming in contact with and irritating the sensitive membranes of the nose. 1
A further object is to rovide means whereby the filterin materia may be quickly and conveniently c langed as desired.v
A further object is to provide means for facilitating the insertion and removal of the device intoand'from the nostril, respectively. The invention will be hereinafter fully set particularly pointed out in the claims.
, In the accompanying drawing :Figure 1 is a top plan view of my Improved surgical device. Fig. 2 is a front View thereof. Fig. 3 isa side view. Fig. 4 is a sectional view on line 44, Fig. 1. Fig. -5 is a detail view illustrating the manner of securing the filtering fabric. 3
' Referring to the drawing, 10, 1 I'designate two filtering members each made up of an outer ring12, and an inner ring 13, conforming to the contour of the first ring, with -a sheet of filtering material 14, such as gauze,
Q grasshnen, chifion, etc. stretched across the open space of the inner. ring and having its edges secured between the:c0ntiguous faces of 0th rings. The. inner rings are connected by a bridge or band 15' the ends of which j are secured to the'inner face of each ring as indicated at 16, in such manner as to practically connect the inner adjacent portions of the filtering members. The rings 12 and 13 are made-0f any suitable material, such as cork, hard rubber, German silver, and the like and are shaped to conform to the contour of the nostril 'i. e. they are substantially e1 liptical in shape, the contiguous or inner sides, however, being substantially straight,

i In practice after the filtering fabric has been stretched across each ring 13 and the edges thereof confined by catching the same between the outer face of ring 13 and the inner face of ring 12, the device is ready for use. The bridge or band 1-5 is grasped in such manner as to readily force the filtering members'into both nostrils, the bridge-or band 15 tering members can be inserted. When it is desired to remove the ,device it is only necessary to grasp the bridge or band 15 and the filtering members can then be readily withdrawn. The advantages of my improved surgical device will be readily apparent.'- It willbe particularly noted that the same is simple and inexpensive in construction, and when the filtering fa ric quickly becomes moistened by the secretions of the nose, thereby greatly adding to the .filtering power ofthe device. It willbe further observed that the fit the nostril in such manner as to be safely retained thereby and that there are 'no' exposed points or protuberances that can 1njure filtering fabric in position and for accomlishing a ready change thereof. It will also lie noted that bfi means of the bridge or. band the device may ereadily inserted into position or removed, as .desired, and that the saine may be readily bent to bring the filter ing memberscloser together or farther apart, as the-conformation of the patients nose requires. It will be further observed that serving to limit the distance to which said filplaced in position will thoroughly filter the: air drawn throu h the nostrils. When in use necessary to, prevent foreign particles from persons residing in localities where sand and I the outer sides being formed on a deeper filtering members are so shaped as to readily the flesh. Another advantage lies' in the simple and efiicientmeans for securing the while I haveshown and described my improximately'flat and the other side arranged on a deep curve, whereby said rings conform to the interior contour of the nostril, the ends of said bridge or'band being secured one to each ring-like member and to the inner face of the flattened portion thereof, whereby the ends of said bridge or band will not lacerate the flesh in placing the rings in the nostril, a
filtering fabric extended across each filter member, and a securing ring for each filter member conforming to the contour thereof and fitting over the outer face thereof to surround the same and clamp said fabric in position, said rings being formedlofthin bands of smooth metal. r In testimony whereof-I'have signed-my name to this specification inthe presence of two subscribing itnesses.
