The present invention relates to a plug, more particularly to a nose plug device allowing users to plug nostril to stop nostril bleeding.
In some embodiments, the present invention discloses a nose plug, nasal depository, or the like to stop nostril bleeding. The nose plug or nasal depository comprises a compressible material to apply a force on the bleeding area inside the nostril, together with a surface coating of a bio-lubricant to ease of removal.
In some embodiments, the nose plug further comprises a venting structure for breathing or for draining fluids within the nostril, such as blood or nasal discharge. The nose plug material can comprise an absorbent material for absorbing fluids within the nostril, such as blood or nasal discharge.
In some embodiments, the present invention discloses a single nose plug, or a pair of nose plugs coupled to each other. In some embodiments, the present invention discloses methods to apply the nose plug.
The present invention relates to a plug, more particularly to a nose plug device allowing users to plug nostril to stop nostril bleeding, such as a nasal depository for absorbing blood and the like from a person nose.
In some embodiments, the nose plug device comprises a compressible material that expands upon releasing to the nostril, which can produce a compression pressure on bleeding area in inner wall of nostril. For example, the device can have a porous structure lake foam which allows the device to be physically compressed. The compressed foam can be recovered to an uncompressed natural size after releasing. This foam recovery force or strength serves as constant compression pressure on bleeding area inside nostril, achieving effect of stopping bleeding. The porous structure of the device can have a function of absorbing blood.
In some embodiments, the device material can also be pre-dehydrated in a pre-compressed form. The device can immediately swell once contacting with blood or moisture. In some embodiments, the device can also be formed in a firm (solid) version instead of compressible foam. Both soft and firm plugs come with different sizes.
In some embodiments, the present invention discloses a single nose plug, or a pair of nose plugs coupled to each other. A single nose plug device may be employed in the circumstances or situations where there would be need for only a single nose plug, such as blood originating through only one nasal passageway. Alternatively, the nose plug device can comprise an integrally shaped nose plug which comprises a connecting piece and a pair of nose plugs on opposing sides. A coupling device might be provided to connect the two nose plugs. The coupling device might also be used to prevent the nose plug from being deeply engaged into the nose.
The device can be made of polymer materials such as polyvinyl alcohol (PVA), polyvinyl chloride (PVC), polyurethane (PU), polyethylene (PE), silicone rubber and hydro gel et al. It can be also made of natural fabrics such as cotton, linen et al.
The nose plug is formed in such as to be easily inserted into a nasal passageway. In some embodiments, in order to remove the device smoothly without causing sealed, coagulated bleeding site to bleed again, the outer surface of the device can be coated with bio-lubricants such as Vaseline, silicone gel or Teflon. Further, the device surface can be coated with coagulants, such as CELOX and thrombin.
CELOX is a new granular hemostatic agent that can provide fast bleeding control by forming a gel-like mass over the bleeding site to protect the wound. It can be easy to clean. It is versatile, and can be used in low temperatures, high pressure, or high volume bleeding from major arteries.
In some embodiments, one or more hollow venting structures are extended through the nose plug which functions to allow the user of nasal depository to easily breathe when the nostrils contain the nasal depository. In some embodiments, the slightly oversized firm plug is inserted into nostril. The stretched wall of nostril creates compression pressure on bleeding area. Both soft and solid versions may have a venting structure for allowing users to breathe in or out. This structure can be a tubular structure in the center of the device. The residual blood and nasal discharge can be drained out through the hole. Venting tube material can be metal or polymer. The tubular structure can be designed like a stent that is expendable in diameter. The nose plug can have an absorbent member for absorbing blood when in contact with nasal blood/fluid. The tubular structure can be configured to be unobstructed by the absorbent member to allow the user to readily breathe.
In some embodiments, the present invention discloses a delivery service to deliver the nose plug to a nostril. The nose plug can be compressed and preloaded to a delivery device. After positioning the delivery at the nostril, the nose plug can be pushed into the nostril, or the delivery device can be retrieved. In some embodiments, the delivery device is first inserted into the nostril, either partially or completely.

The nose plug then can expanded, e.g., released from the compressed from, to fill the interior volume of the nostril. The nose plug is preferably larger than the nostril volume, thus exerting a compressive pressure on the interior wall of the nostril, helping stop the bleeding.
In some embodiments, the outside surface of the nose plug is coated with a bio-lubricant, which can help in the process of preloading to the delivery device. Further, the lubricant coating can also help in the nose plug removal process, for example, assisting in preventing being attached to the skin, and to eliminate or reducing friction in removing the nose plug. The lubricant coating can also eliminate or reducing the bonding of the coalescent blood to the nose plug, facilitating the removal process.
In some embodiments, the outside surface of the nose plug is coated with a coagulant, which can help in stopping the flow of blood in the nostril. In some embodiments, the nose plug comprises a venting hole.
