DETAILED DESCRIPTION OF THE INVENTION

[0015] FIG. 1 is an angled view and FIG. 2 is a cross section of a nose-bleed stopping device 10 for insertion into a nostril of a patient's nose that has bleeding that is difficult to control. The device 10 consists of an upper portion 11 that is slightly tapered (or it could be cylindrical) that is formed as a single piece of sponge-like material with a handle 12, which handle is used as a convenient means for inserting the upper portion 11 of the device 10 into the nose and also for removing the device 10 from the nose after the bleeding from the nose has been stopped. The upper portion 11 has a coating of chitosan or and equivalent blood clotting agent that is able to cause blood to clot. The chitosan can be a coating of the upper portion 11 and it could also be contained for a short distance inside the outer surface of the sponge-like material from which the upper portion 11 is formed.

[0016] The bottom portion of the device 10 is a handle 12 that is formed as one piece with the upper portion 11 from a sponge-like material such as that which is used for ear plugs. The handle 12 is used for both inserting the upper portion 11 into the nostril and removing the device 10 from the nostril after the bleeding has been stopped by the chitosan coating of the upper portion 11 having been exposed to the opening in the nostril where from which the bleeding originates.

[0017] Another novel feature of the device 10 is a hole 15 that extends in the axial direction 2 through the entire length of the upper portion 11 and the handle 12. If there is free blood that has flowed into the nasal cavity prior to the insertion of the device 10, then this free blood can come out of the nose through the hole 15. Once there is no blood flowing through the hole 15, it can be used for the patient to breathe through that hole until the device 10 is removed from that person's nostril.

[0018] Referring to FIGS. 1-4, there is provided blood clotting device 10 for insertion into the nostril of a patient. As is seen in FIGS. 1 and 2, the blood clotting device 10 is formed of an upper portion 11 and a handle 12 adapted to be grasped by the patient for insertion and retraction of upper portion 11 into and out of the patient's nostril. In any event whether upper portion 11 and handle 12 are formed of a single composition or of different compositions, both sections are joined together to form a one piece tubular member. However, it is evident that handle 12 and upper portion 11 may be formed of different material compositions with the only limitation being the flexibility of upper portion 11. It is envisaged that handle 12 may be formed of either a flexible or rigid composition such as a plastic or rubber composition.

[0019] Blood clotting device 10 includes a through passage or hole 15 which extends throughout the length of the handle 12 and the upper portion 11 to provide an unrestricted flow path for passage of air and/or blood. As is seen in FIG. 2, the hole 15 extends in axial direction 26 to provide for the unrestricted flow path.

[0020] Blood clotting device upper portion 11 may be formed of an open cell plastic composition, a closed cell plastic composition, or composed of some type of porous material consisting of a fibrous skeleton formed from an invertebrate or other synthetic material. In a preferred embodiment, the handle 12 and the upper portion 11 are formed of a sponge composition with the important consideration being that the upper portion 11 defines a flexible upper portion 11. Handle 12 may be in the preferred embodiment formed of a sponge material of the same composition material as the upper portion 11 to provide a flexible overall insert into the patient's nostril. In some embodiments handle 12 may be formed of a hardened material such as a rigid plastic which is adhered to upper portion 11 by glue or other type of bond.

[0021] As is clearly seen in FIGS. 1 and 2, the upper portion 11 is tapered in axial direction 26 to allow ease of insertion into the patient's nostril. Upper portion 11 is generally formed in the shape of a truncated cone to permit insertion/retraction of the blood clotting device 10 without irritation to the patient.

[0022] Blood clotting composition 14 may be formed or comprised of a chitosan or some other type of blood clotting composition, for example, comprising one or more of fibrinogen and thrombin mixtures, thrombin, Factor XIII, Factor X, Factor VII (of human, animal, or synthetic origin), oxidized regenerated cellulose, cellulose, collagen, keratin, gelatin, chitosan, chitin, alginate, dextran, cyanoacrylate, PEG, albumin, glutaraldehyde, kaolin, bentonite, laponite, montmorillinite, galodinium, and aluminum chloride. In use, blood clotting composition 14 may be coated on an exterior surface of upper portion 11 and/or impregnated therein when upper portion 11 is formed of an open cell plastic or sponge composition. In all cases, blood clotting composition 14 forms a coating on upper portion 11 to provide contact with a bleeding blood vessel.

[0023] Again as seen in FIGS. 1-4, tapering of the upper portion 11 is seen in FIGS. 1 and 2, where upper portion 11 defines an upper surface 28 having an exterior diameter 20 which is less than the diameter 22 of lower surface 30 of upper portion 11.

[0024] As seen in FIG. 2, the upper portion 11 includes tapering angle 32 which in general has a tapering angle of less than 10 degrees with respect to axial direction 26. In cross-section, upper portion 11 takes the form of an annular contour defined by the outer surface of the blood clotting composition 14 and the through passage 15 as seen in FIGS. 1-4.

[0025] Handle 12 additionally defines an annular cross-section with respect to axial direction 26 and provides for an outer diameter 25 which is less than the upper portion lower surface 30 diameter 22. The dimensional relationships of the upper portion 11 and the handle member 12 are depicted in FIGS. 3 and 4 showing both top and bottom views of the blood clotting device 10.

[0026] To accommodate various sizes of noses that could have bleeding controlled by the device 10, it is expected that the device would come in different lengths and diameters to accommodate different sizes of a human nostril. The range of sizes would be from as large as 1.0 cm in diameter for the major diameter of the upper portion 11 or as small as 0.3 cm diameter to accommodate a very small nostril. The length of the upper portion 11 would be approximately 2 cm with a maximum possible length of 4 cm and a minimum possible length of 1.0 cm. The taper angle 32 of the upper portion 11 could be as little as zero degrees or as much as 10 degrees with an optimum taper being approximately 3 degrees. Although the handle 12 could have a great variety of lengths and diameters, an optimum diameter would be about 2 mm smaller than the diameter 22 at the bottom of the upper portion 11 and the length could be anything from cm to as long as 5 cm. The hole 15 that extends through the entire length of the device 10 could have a diameter as small as 1.0 mm to as large as 7 mm with an ideal diameter being approximately 4 mm. It is contemplated that the upper portion 11 exerts an outward force on the inner surface of the bleeding nostril of the patient to promote the stopping of the bleeding.

[0027] In one step of a method for the treatment of a bleeding nostril of a human nose, a device from a sponge-like material that has an upper portion that is formed integral with a handle, the outer surface of the upper portion being coated with a material that causes blood to clot is provided to the person with a bleeding nostril. In a further step, the device is inserted into the nostril of the human nose where the bleeding originates by holding the handle with the thumb and at least one other finger. In a furthers step, the device is removed by pulling downward on the handle after the bleeding has been stopped.

[0028] Various other modifications, adaptations and alternative designs are of course possible in light of the teachings as presented herein. Therefore it should be understood that, while still remaining within the scope and meaning of the appended claims, this invention could be practiced in a manner other than that which is specifically described herein.
