Technical Field
The present invention relates to a nasal device and in particular, but not exclusively, to a nasal device for use as a speech aid or teaching device. Such devices may be used to assist patients in improving the quality and volume at which they can speak by controlling the breathing pattern or method of the patient. Such devices are typically removably inserted into one or both nostrils of a patient.
Background
It is known to provide a patient with a nasal implant to improve airflow through the nasal passages of the patient. One example of such a device is disclosed in US2017/0100275, which provides a nasal breathing assistance device having one or more open-ended tubular elements with coupling elements connecting the ends thereof. The implants are inserted into the patient's nares and help reduce snoring by increasing airflow through the nasal passages. The device allows a patient to exhale and exhale without significantly restricting the airflow. A filter may be provided to filter the inhaled air.
It is also known to provide a filter within an implant inserted into the nasal passages of a patient in order to filter the air inhaled by the patient. One example of such a device is disclosed in US 2010/0331777 which provides an implant for insertion into a nasal passage, the implant including a thread on its outer surface which allows the implant to be screwed into the nasal passage in a manner which allows the thread to engage with the passage and hold the implant in place. A filter is provided within the implant to filter any air inhaled by the patient.
While the above-described devices provide a completely suitable solution to keeping the nasal passages open and may also be adapted to filter inhaled air, they are not suitable for use in controlling the breathing of a patient in themselves and do not limit or eliminate the exhalation of air through the nose, which is required to teach a patient to inhale through the nose and exhale through the mouth or otherwise improve the patient's breathing pattern or method.
Disclosure of Invention
The object of the present invention is to solve the above problems by providing a nasal implant that can reduce the possibility of a patient exhaling through the nose and, if desired, can eliminate the possibility of a patient exhaling through the nose while allowing the patient to exhale through the nose without significant restriction.
Accordingly, the present invention provides a nasal breathing control device comprising: one or more axially extending cylinders having a first end, a second end, a middle portion, and an inner cavity having a first inner end and a second inner end and extending along a longitudinal axis; a first opening in the first end is connected to the lumen; a second opening in the second end connected to the lumen; a float having a first end and a second end within the lumen and movable between a first position in which the float closes the first opening and a second position in which the float partially closes the second opening; wherein each of the one or more axially extending cylinders (12) is tapered, and wherein a cross-section of each of the one or more cylinders (12) comprises a width (W) that decreases from the first end (14) toward the second end (16) of the cylinder.
Preferably, said first opening is on said longitudinal axis (X) and said second opening comprises one or more openings radially displaced from said central axis (X). This arrangement allows airflow around the outside of the float even when the float blocks a portion of the opening.
In one arrangement, the second opening further comprises an opening on the central axis (X). This arrangement allows for increased airflow through the device when the central opening is not closed.
The float may comprise an intermediate portion between said first end and said second end, and wherein at least said second end comprises a tapered cross-sectional profile having a width (W) that increases from a minimum value (wmin) at said second end towards said intermediate portion to a maximum value (wmax). Such an arrangement would allow the second end to contact the second inner end of the inner cavity without closing the one or more radially displaced openings.
The float may include an intermediate portion between the first end and the second end, wherein the first end includes a tapered cross-sectional profile having a width (W) that increases from a minimum value (wmin) at the first end to a maximum value (wmax) toward the intermediate portion. This arrangement will allow the first end to contact the first inner end of the inner cavity (20) and close the centrally located opening.
The first end of the float includes a hemispherical surface. The second end of the float includes a hemispherical surface. The hemispherical surface will allow the float to settle into any one of a number of angular positions while still performing the desired sealing function.
In a preferred arrangement, the float is spherical. Such a shape will allow the float to be naturally stable regardless of angular position.
In one arrangement, the inner lumen has an inner Diameter (DI) and the float has an outer Diameter (DE), and wherein the inner Diameter (DI) is greater than the outer Diameter (DE) of the float by an amount G, thereby providing a flow path between the float and the inner Diameter (DI) of the lumen. In an alternative arrangement, a passage (not shown) may be provided in the float or the chamber to provide the desired flow path.
In a preferred arrangement, the device comprises a circumferentially extending protrusion at the first end of the cavity, the protrusion having an inner diameter D2 that is smaller than the outer diameter DE of the float. This arrangement effectively forms the first opening and also helps to retain the float within the cavity. Advantageously, the circumferentially extending protrusion extends a full 360 degrees around the inner surface of the cavity.
Preferably, the arrangement comprises two cylinders, wherein each cylinder has a longitudinal axis (X) extending parallel to the other cylinder, and each cylinder is connected to the other cylinder by a bridge portion at the first end of the respective cylinder. This arrangement ensures that the cylinders remain together and may also allow the bridge portion to be used to remove the device from the patient's nares.
Preferably, the one or more cylinders comprise an elastically deformable material. The protrusion may also comprise a resiliently deformable material. Still further, the bridge portion may further include an elastically deformable material. In a preferred embodiment, the nasal device comprises a pair of
The device may comprise a plastics material or silicone rubber. The device may comprise a plastics material or silicone rubber. Such a material is suitable for being moulded and for inserting or removing the float into or from the barrel.
In a preferred arrangement, the apparatus comprises: two cylinders, each cylinder having a longitudinal axis (X) extending parallel to each other; a bridge portion at a first end of each respective cylinder connecting the cylinders; a projection extending circumferentially within the first end of each cylinder; wherein the two cylinders, the bridge portion and the circumferentially extending groove in each cylinder comprise deformable silicone rubber.
