The present invention relates, in general, to the treatment of epistaxis, more commonly referred to as nosebleed. More particularly, the present invention relates to a device and a method for the treatment of nosebleed, as well as a nosebleed package containing the device.
Nosebleeds are a common non-physiological cause of bleeding. The majority of nosebleeds in humans occur as a result of hypertension, long-term infection, leukemia, vitamin K deficiency, blows to the nose, sneezing, nasal drug abuse, allergic rhinitis, use of blood thinners or children picking their noses with sharp fingernails. Nosebleeds often occur without warning and can be extremely dangerous if not controlled promptly and properly. Excessive loss of blood may result in unconsciousness and death. Children and the elderly are particularly susceptible to serious, acute nosebleeds.
To the best of applicant's knowledge, the most pertinent of all the prior art methods for control of nosebleeds is disclosed in “Nosebleeds in Pediatrics”, which is a chapter written by Carol Berkowitz in a book entitled Primary Care Approach (published 2000) by Stanley H. Inkelis, M.D. This reference discloses that children who are actively bleeding through the nose should be positioned sitting upright while leaning forward slightly and that direct pressure should be applied and that a cotton dental roll may be placed under the upper lip to compress the labial artery in older children for whom concern about displacement and possible aspiration of the cotton is minimal.
General background information relevant to attempts to control nosebleeds can be found in U.S. Pat. Nos. 5,899,918; 3,884,241; 4,457,756; 4,646,739; 5,383,891; 5,584,822; 5,584,827; 5,391,179; and 5,011,474. These patents describe devices and methods for controlling nosebleeds that involve pinching the nose with external or internal clips, packing the nasal cavity with absorbent tampons, or using special hemostatic devices that require skilled medical training. However, these devices and methods suffer from numerous disadvantages.
More specifically, the described methods of pinching the nose seek to control nosebleeds by applying pressure to an area of the septum known as Kiesselbach's plexus (also called Little's area). However, pinching the nose is not only uncomfortable but also is difficult for small children to administer to themselves.
Likewise, the described tampons for packing the nasal cavity seek to control nosebleeds by applying pressure to Kiesselbach's plexus, and such tampons are both uncomfortable and difficult to administer. Moreover, the tampons can damage the nasal passageway due to necrosis from undue pressure or overpacking. Also, prolapse of the tampon into the pharynx is a dangerous risk. Hence, use of nasal tampons in small children and the elderly must be continually monitored. Additionally, the tampon may dry out and stick to the delicate nasal mucosa, making removal of the packing painful and presenting a risk of the bleeding recurring.
Furthermore, both pinching the nose with the fingers or other device and packing the nose with a tampon interfere with normal nasal breathing. Consequently, the patient must breath through the mouth, which may result in uncomfortable drying of the mouth, throat irritation, and middle-ear complications.
With regard to the number of sophisticated hemostatic devices to control nosebleeds on the market, such sophisticated devices are not only time-consuming to administer but also require the skills of a physician or other trained medical personnel in a medical treatment facility, such as a hospital. Thus, these devices are unsuitable for the prompt treatment of the vast majority of nosebleeds that happen in the home, office, or school. Nevertheless, home remedies, such as tilting the head, applying cold compresses to the nose or manually compressing the nose, typically are ineffective in stopping nosebleeds promptly.
Hence, a long felt need still exists for a readily available device and method for treating nosebleeds that can be effectively used by untrained laypersons away from medical treatment facilities.
Accordingly, the present invention provides a device for treatment of nosebleeds. The device comprises an elongated body configured to be positioned between the upper gum and the portion of the face below the nose and above the top lip of a human so as to exert pressure on an area of nasal vascularization of the human.
Also, the present invention provides a method of treating a nosebleed in a human having a nosebleed. The method comprises providing a nosebleed device comprising an elongated body configured to be positioned between the upper gum and the portion of the face below the nose and above the top lip of the human, and positioning the device between the upper gum and the portion of the face below the nose and above the top lip of the human so as to exert pressure on an area of nasal vascularization of the human, and achieving alleviation of the nosebleed.
Additionally, the present invention provides a nosebleed package comprising in combination a container having a sterile inside environment and a device for treating nosebleeds, the device being disposed inside the container and comprising an elongated body configured to be positioned between the upper gum and the portion of the face below the nose and above the top lip of a human so as to exert pressure on an area of nasal vascularization of the human.
Furthermore, the present invention provides a box containing a multiplicity of nosebleed packages comprising individually packaged nosebleed devices. Each nosebleed package comprises a nosebleed device in combination with a container having a sterile inside environment, and each nosebleed device is disposed inside the container. Also, each nosebleed device comprises an elongated body configured to be positioned between the upper gum and the portion of the face below the nose and above the top lip of a human so as to exert pressure on an area of nasal vascularization of the human.
Therefore, it is an object of the present invention to provide a device and a method for treating nosebleeds that require neither medical treatment facilities nor detailed medical training or expertise for use of the device and method.
It is another object of the present invention to provide a nosebleed treatment device in sizes appropriate for different age groups or mouth sizes.
It is still another object of the present invention to provide a device for the treatment of nosebleeds such that the device may be disposed of after a single use.
It is a further object of the present invention to provide a device for treating nosebleeds where the device is supplied in a container having a sterile inside, the container being suitable for convenient transport and single-use application of the device.
It is an advantage of the present invention that the device causes minimal, if any, discomfort, does not interfere with normal nasal breathing, and can be effectively and quickly used by laypersons without medical training.
Other features, aspects and advantages of the present invention will become better understood with reference to the following description, accompanying drawings and appended claims.
Although the nosebleed devices are described below in a preferred embodiment with a circular cross section, the devices could also have a non-circular cross-sectional shape that could increase the surface area. Other cross-sectional shapes may include, but are not limited to, oval, triangular, square, rhomboid, parallelepiped, pentagon, hexagon, and the like.
Hence, the term “diameter” as used here is intended to mean the transverse length of the cross section, regardless of whether the cross section is circular or some other shape.
Suitable diameters for the inventive devices described below may range from about 4 mm to about 12 mm, and of course, the diameter may be from about 5 mm to about 11 mm, or from about 6 mm to about 10 mm.
Typical lengths of the device range from about 30 mm to about 80 mm, more particularly from about 35 mm to about 75 mm, more particularly from about 40 mm to about 70 mm, and even more particularly about 50 to about 60 mm.
The diameter and/or the length of the device can vary depending on several factors such as the size of the person to be treated and the like. In general, a device with a smaller diameter and/or a shorter length will be suitable for a small person, for instance, a child.
The phrase “area of nasal vascularization” as used here is to be broadly construed. The area of nasal vascularization includes, but is not limited to, the superior labial artery and other arteries in the face and head that are conduits to Kisselbach's plexus, such as the angular artery, the facial artery, the anterior ethmoidal arteries, the posterior ethmoidal arteries, the sphenopalatine artery, or combinations thereof.
The term “compression padding” as used here refers to a part of the nosebleed device that should enhance the effect of the device on the area nasal vascularization. The compression padding is disposed on a portion of the device, in one embodiment as further described below.
The terms “treatment” and “treating” as used here in regard to a method of treating a nosebleed in a human having a nosebleed refer, in general, to accelerating the cessation of a nosebleed and/or accelerating the slowing of the nosebleed. Treatment with the inventive device should result in alleviation of a nosebleed by stopping and/or slowing the flow of blood into Kiesselbach's plexus so that natural coagulation mechanisms are enabled.
Nevertheless, the inventive nosebleed device is primarily intended for treatment of an anterior nosebleed. An anterior nosebleed is one that comes from the front part of the nose and begins with a flow of blood out of one or both nostrils if the patient is sitting up or standing, whereas a posterior nosebleed is one that comes from deep in the nose and flows down the back of the mouth and throat even if the patient is sitting up or standing. The anteroinferior portion of the nasal septum, generally about 5 cm from the tip of an adult nose, known as Kiesselbach's plexus or Little's area, is the most common part of the nose involved in anterior nosebleeds. Kiesselbach's plexus is supplied blood by the anterior and posterior ethmoidal arteries, the sphenopalatine artery, and the septal branches of the superior labial artery. On the other hand, the turbinate or nasal wall is the most common part of the nose involved in posterior nosebleeds, and significant bleeding, i.e., a nasal hemorrhage, may occur during a posterior nosebleed from a branch of the sphenopalatine artery.
It is not believed that the nosebleed device provided here functions adequately with respect to efficient hemostatis, such as after septal, sinus, or rhinoplastic surgery. Further, the device is not believed to function adequately with respect to abating nasal hemorrhage (posterior nosebleed), the posterior nosebleed requiring a trained medical person to control significant bleeding, usually from ruptured major arteries and blood vessels over substantially all parts of the nasal cavity.
Hence, by the phrase “alleviate the nosebleed” as used here, it is not intended to include stopping the nosebleed in every instance as some of those instances will be a nasal hemorrhage from a posterior nosebleed, in which instances the nosebleed most likely will not stop and so professional medical assistance should be sought to stop the bleeding.
The present invention is directed to satisfying the need for a device and method of treating nosebleeds that can be effectively used not only by medical professionals but also in the home or other non-medical facilities by non-medical personnel. The invention comprises a nosebleed device that preferably is a generally cylindrical shaped pad that is used as a lip pack. The lip pack is placed between the upper gum and the portion of the face between the top lip and the bottom of the nose.
The lip pack is configured so as to fit comfortably along the anatomical contours of the portion of the mouth where the lip pack is placed. The lip pack is further configured so as to apply hemostatic pressure on an area of nasal vascularization, typically the superior labial artery. To the best of applicant's knowledge, there are no known devices presently commercially available that are designed to treat nosebleeds by the application of pressure on the area of nasal vascularization, such as the superior labial artery, from inside the mouth.
The pad for use as a lip pack may be constructed of materials such as gauze, cotton, polyurethane, rayon, rubber, polysorbate, polyvinyl alcohol, and the like. Preferably, a material should be relatively soft and pliable. Even more preferably, dense porous materials are preferred as they absorb liquids such as saliva or water, and thus, may be wetted, for instance with water, prior to positioning, which should make insertion and retention of the inventive nosebleed device more comfortable. For instance, a suitable dense porous material is foamed polyvinyl alcohol.
The portion of the face below the nose and above the top lip and also the natural tightness of the interface of that portion with the upper gum should hold the nosebleed device in place. The effect of the nosebleed device may be augmented by applying gentle pressure with a finger or fingers above the top lip, directly over the region occupied by the pad. Used as directed, the nosebleed device should be painless, and should not interfere with breathing or eating. Moreover, the device avoids the complications from undue pressure or overpacking of the nasal cavity attendant many prior art devices. The ease of use of the device makes it suitable for self-application and self-removal by the average layperson, including children and the elderly.
The lip pack treats nosebleeds by exerting pressure on an area of nasal vascularization, for instance the major arteries supplying blood to the nose. Treatment of a nosebleed with the inventive lip pack should result in control of the flow of blood to the nose such that the flow of blood is curbed or slowed. Suitably, treatment of the nosebleed is to the extent of stopping the flow of blood. If the nosebleed does not abate within approximately 30 minutes, the patient should seek medical attention from a trained professional, as most likely the nosebleed is the posterior kind.
In order to treat a nosebleed quickly and effectively without the aid of medical personnel, a preferred embodiment of the device comprises a lip pack composed of a soft, flexible pad that can be easily positioned between the upper gum and the portion of the face beneath the nose and above the top lip, the pad being a flattened cylinder, i.e., generally elliptical in cross-section, to apply hemostatic pressure to the major arteries supplying blood to the nose.
In an even more preferable embodiment, a portion of the lip pack has longitudinally disposed compression padding. When the lip pack is positioned intra-orally, the compression padding should be in the direction that is upward toward the nose so as to increase the pressure on the area of nasal vascularization as compared to a lip pack absent the extra compression padding.
Additionally, the lip pack preferably is packaged in a container having a sterile inside, but still typically is inexpensive, simple to use, and can easily be carried in a purse or pocket, much like BAND-AID® brand bandages marketed by Johnson & Johnson. When the lip pack is needed, a nosebleed victim can remove the lip pack from its sterile packaging and self-apply the lip pack to control a nosebleed without the assistance of a medical professional.
With reference now to the drawings, where like reference numerals designate corresponding or similar elements through the several views, shown in
Thus, the lip pack 20 is generally configured in the shape of a cylinder so as to fit comfortably between the upper gum (not shown) and the portion of the face beneath the nose and above the top lip (not shown). The large adult-sized lip pack 20 may be about 60 to about 70 mm in length and the next smaller adult-sized lip pack 20 may be about 50 to about 60 mm in length, whereas the child-sized lip pack 20 may be about 30 to about 40 mm in length.
The lip pack 20 is preferably made of a pliable material so that the lip pack 20 can conform, such as by curving or flattening, to the anatomical contours of the mouth (not shown) after intra-oral placement. Also preferably, the lip pack 20 is made of a material that absorbs liquids, such as saliva and/or water.
As discussed above, the lip pack may be composed of a soft, resilient material such as gauze, cotton, rubber, rayon, polyurethane, polysorbate, polyvinyl alcohol, or combinations thereof, and preferably is a dense porous material. The advantage of such a resilient material is that it readily conforms to the anatomical contours of the mouth, and thus, is comfortable to use. For situations where reuse of the lip pack is desirable, the lip pack may be made of plastic or rubber. Techniques for manufacturing pads of this kind of material in a generally cylindrical shape are well known to those skilled in the art.
The lip pack 30 may be of unitary construction so that the compression padding 39 is integral with the lip pack 30, or the lip pack 30 may be constructed so that a separate compression padding 39 is attached to the lip pack 30. Thus, the compression padding 39 may be composed of the same material as the rest of the lip pack 30, or a different material, all of these materials preferably being chosen from one or more of those noted above. The purpose of having the compression padding 39 is to exert more pressure on the area of nasal vascularization after intra-oral placement of the lip pack 30.
The compression padding 39 in the child and adult versions of the lip pack 30 would be appropriately proportioned so as to apply hemostatic pressure over a small or larger area, respectively. In general, the compression padding 39 should be about 1 to about 4 mm, more preferably about 2 to about 3 mm thick and should have a length about a quarter to about two-thirds, more preferably about a third to about a half of the length of the lip pack 30.
The natural tightness of the interface 51 between the upper gum 43 and the portion 45 holds the lip pack 42 in place. Through the natural tightness of the interface 51, the lip pack 42 suitably controls nasal bleeding by exerting pressure on the area of nasal vascularization 52, such as the superior labial artery 53, thus slowing blood flow to the Kiesselbach's plexus 54 and helping to enable natural coagulation mechanisms to occur so bleeding should stop. If desired, firmer pressure may be applied by pressing with a finger or fingers on the outside of the facial portion 45 just over the lip pack 42. When the nosebleed has stopped, the lip pack 42 is easily removed by the fingers or sliding the tongue.
An important advantage of this invention is that removal of the lip pack is typically pain-free and should not present a risk of re-bleeding because no devices are inserted into the nasal cavity. Another advantage of this invention is that when the lip pack 42 is positioned as described, the nasal cavities 55 and 57 remain unobstructed so the patient is able to breathe normally through the nose 47.
