Definitions
- This invention relates to a device adapted for temporary insertion within the nose for establishing and/or maintaining an airway through the nasal passages and delivering medicament thereinto
- Figure 1 is a front elevational view of the present invention
- Figure 2 is a perspective view of the device shown in Figure 1
- Figure 3 is a side view of the device of Figure 2 viewed in the direction of line 3-3'
- Figure 4 is a perspective inferior view of the device in accordance with the present invention positioned when the device is positioned within the nose of a person
- Figure 5 is a schematic lateral view of the device positioned within the nose which has been partially cut-a-way for illustration
- Figure 6 is a perspective view of an embodiment of the invention having gripping pins adapted for facilitating instrument assisted insertion of the device into the nose
- Figure 7 shows the cooperative functional relationship between the insertion instrument and the device of Figure 6 prior to insertion of the device into the nose
- Figure 8 is an elevational view of the device of Figure 6 looking upward into the nose with the device properly positioned for operation
- the device 10 shown in front (anterior) elevational view in Figure 1, is a unitary strip of elastically deformable material, preferably hypoallergenic, elastomer shaped to form a symmetrical 3-d ⁇ mens ⁇ onal structure as generally shown in Figure 2
- the device is bifurcated and symmetrically disposed in structure with respect to the medial septum attachment portion 1 1
- the septum attachment portion 11 is a semi-cylindrical arcuate distal coterminous for the inferior or distal end of the extension portion 14 and 14' of the device, connecting the tines 14 and 14' of the extension portion to one another and having an inner diameter D
- the extension portion consists of tines 14 and 14' and extends proximally, away from the septum attachment portion a distance L, the proximal terminus of the extension portions 14, 14' being shown at 15
- the dilating portion consists of two "U" shaped projections projecting anteriorly on a plane at right angles to the extension portion 14, to
- the proximal end 15 of the device 10 can be advanced no further into the nasal passages 42 and the anatomically conforming tissue-contacting surfaces 13 and 13 ' comprising the dilating portion press laterally against the anterior and lateral wall of the nasal passage to dilate the passage and maintain an airway therethrough.
- the above described embodiment is shown in Figure 5 wherein the device is seen to be comfortable positioned within the (partially sectioned) nose 40 of the patient.
- the surfaces 13 and 13' elastically urge outward to press laterally outward against the wall of the nasal passage and provide a smooth, non-irritating tissue-contacting surface for comfort.
- FIG. 6 is a perspective view of an embodiment of the invention including gripping pins 61 adapted to be grasped by an instrument 62 for facilitating instrument assisted insertion of the device 10 into the nose.
- Figure 7 shows the cooperative functional relationship between the insertion instrument 62 and device 10 prior to insertion of the device into the nose.
- the tines 14 and 14' of the extension portion of the device are urged toward one another in the direction indicated by the broad arrows in Figure 7 and the proximal end 15 inserted into the person's anterior nasal passages and advanced thereinto by means of the instrument 62.
- the tines of the extension portion bear against the lateral tissue surfaces of the medial nasal septum to stabilize the while the proximal arcuate tissue-contacting surfaces of the dilating portion buttress a portion of the inner perimeter of the nasal passages, urging the tissue in contact therewith radially outward to create and maintain symmetrically disposed open nasal airways.
- Figure 8 is an elevational view looking upward into the nose 40 showing the device 10 properly positioned in accordance with this invention for maintaining an open airway within the nose.
- Medicament saturated dispensing pads 81 may be affixed to the inner surface 82 of the dilating portion of the device to release a volatile medicament contained therein to be entranced in the air stream and delivered to tissues leaving the resuscitator tract.
- the tissue-contacting surface 13 may be open cell and permeated with a medicament or the material comprising the device may be porous.
- a thin film of silicone oil or a hydrogel or silicone gel coating containing a releasable medicament may be applied to the tissue-contacting surface of the device to be transported by diffusion into the mucocutaneous membrane within the nose.
- Appropriate medicaments include, for example, antibiotics, steroids and volatile compositions exhibiting a therapeutic effect. While particular embodiments of the present invention have been illustrated and described, it would be obvious to those skilled in the art that various other changes and modifications can be made without departing from the spirit and scope of the invention.
- the device 10 is stabilized within the nose by contact with the lateral walls of the nasal septum and the interior surface of the nostrils. Accordingly, the device may be used for correcting a deviated septum. It is therefore intended to cover in the appended claims all such changes and modifications that are within the scope of this invention. What I claim is:
