Description

[Technical field]

[0001] The present disclosure relates to nasal elements, and more particularly to nose drops, nasal cannulas, nebulizers or nasal dilators that include nasal elements, as well as methods of using and manufacturing nasal elements. [Background technology]

[0002] The nasal members are articles or components of the device designed to engage the user's nostrils. The nasal members may be intended to allow delivery of a substance to the nasal passages, for example when provided as part of a nose drop, nasal cannula, or nebulizer. The nasal members may also (or in addition) be intended to open the user's nostrils, for example when provided as or part of a nasal dilator.

[0003] The size of the nasal members relative to the size of the user's nostrils is often important to maximize the benefit of the article or device. For example, when nasal members are used to deliver a substance to the nasal passages, the efficiency of delivery of the substance can be affected by factors including the degree of seal between the nasal members and the nostrils and the location of the exit orifice of the nasal members relative to the user's nasal cavity. When nasal members are used to dilate the nasal passages, the efficiency and comfort of the dilation will be affected by factors including the size of the nasal members relative to the size of the user's nostrils.

[0004] Typically, nasal members are provided in only a single size per device for reasons of manufacturing economy etc. This may result in less efficient substance delivery or nostril dilation for many users given the wide range of user nostril sizes. Summary of the Invention

[0005] One embodiment of the present disclosure provides a nasal member comprising a body having a tip for insertion into a range of nostril sizes, the body comprising: a first flared section extending longitudinally away from the tip; a second flared section also extending longitudinally away from the tip; and the first flare section is closer to the tip than the second flare section; the first flared section defines a first abutment zone for engaging a first nostril having a first range of sizes; the second flared section defines a second abutment zone for engaging a second nostril having a second range of sizes; The first abutment zone has a maximum flare angle that is greater than the maximum flare angle of the second abutment zone.

[0006] Advantageously, the nasal members of the present disclosure can provide an improved seal in a wide range of nostril sizes. Providing separate first and second flared sections can allow a single nasal member to be suitable for use by both adult and pediatric users.

[0007] For example, the first flare section can be configured for use by a pediatric user or a sub-range of pediatric users, hi some examples, the first flare section can be configured for use by users ages 0-5.

[0008] For example, the second Flare section may be configured for use by adult users (and optionally older pediatric users). In some examples, the second Flare section may be configured for use by users ages 5 and older, and optionally ages 18 and older.

[0009] Configuring the first abutment zone to have a larger maximum flare angle than the second abutment zone can be advantageous in better configuring the nasal members for both pediatric and adult users. In particular, pediatric users, especially those under the age of 7, have a relatively large variation in nostril diameter. For this reason, it has been found that providing a relatively large maximum flare angle in the first abutment zone, and thus a steeper slope in the nasal members in this region, is advantageous in accommodating the large variation in nostril diameter without inducing overinsertion.

[0010] Advantageously, the nasal members of the present disclosure can provide a single nasal member that can be used by many users, and potentially by users of all ages. The nasal member can also simultaneously increase the comfort and efficiency of the nasal member by better configuring the location of the abutments of the nostrils and the nasal member for a range of users having a range of nostril sizes. In addition, the nasal member can be more suitable for use by both male and female users, who may typically have a range of different nostril sizes.

[0011] Advantageously, the nasal members of the present disclosure can reduce manufacturing costs and complexity of the device by avoiding (or at least reducing) the need to provide a range of separate nasal members of different sizes for a single device.

[0012] The first abutment zone can include all or a portion of the first flare section. The second abutment zone can include all or a portion of the second flare section.

[0013] The first and / or second flared sections of the nasal members can have circular symmetry about the longitudinal axis of the nasal members, or the first and / or second flared sections of the nasal members do not have circular symmetry about the longitudinal axis of the nasal members, e.g., the outer diameters of the first and / or second flared sections can be different from front to back and side to side.

[0014] The maximum flare angle of the first abutment zone can be 35° to 65°, preferably 40° to 60°, more preferably 58°, and / or the maximum flare angle of the second abutment zone can be 10° to 30°, preferably 15° to 25°, more preferably 18°.

[0015] In some examples, the flare angle of the first abutment zone can be constant along the length of the first abutment zone. For example, the first abutment zone can be provided by a frusto-conical section of the body. The constant flare angle of the first abutment zone can be, for example, between 35° and 65°, preferably between 40° and 60°, and more preferably 58°.

[0016] In alternative examples, the flare angle of the first abutment zone can vary along its length. For example, the first abutment zone can be provided by a concave (as viewed from the outside of the nasal member) section of the body, or alternatively a series of frusto-conical sections. The flare angle can vary, for example, from a minimum flare angle of 15°-20° to a maximum flare angle of 35°-65°, preferably 40°-60°, more preferably 58°. In embodiments where the first abutment zone is concave, the first abutment zone can have a constant or variable radius of curvature along its length.

[0017] In some examples, the flare angle of the second abutment zone can be constant along the length of the second abutment zone. For example, the second abutment zone can be provided by a frusto-conical section of the body. The constant flare angle of the second abutment zone can be, for example, 10° to 30°, preferably 15° to 25°, and more preferably 18°.

[0018] In alternative examples, the flare angle of the second abutment zone can vary along its length. For example, the second abutment zone can be provided by a concave (as viewed from the outside of the nasal member) section of the body, or alternatively a series of frusto-conical sections. The flare angle can vary, for example, from a minimum flare angle of 5°-10° to a maximum flare angle of 10°-30°, preferably 15°-25°, more preferably 18°. In embodiments where the second abutment zone is concave, the second abutment zone can have a constant or variable radius of curvature along its length.

[0019] Preferably, the longitudinal length of the first abutment zone and / or the first flared section is less than the longitudinal length of the second abutment zone and / or the second flared section. Advantageously, this can help prevent the tip of the nasal member from being over-inserted into the nostrils of a pediatric user, particularly a user under the age of 7.

[0020] In some embodiments, the first abutment zone extends at least 5.0mm to 7.0mm longitudinally from the tip, which has been found to be a beneficial location for engaging the nostrils of a pediatric user and having good positioning of the tip of the nasal member relative to the nasal valve of the nasal cavity.

[0021] In some embodiments, the second abutment zone extends at least between 12.0 mm and 15.0 mm longitudinally from the tip, optionally at least between 12.0 mm and 20.0 mm longitudinally from the tip, optionally at least between 10.0 mm and 20.0 mm longitudinally from the tip, which has been found to be a beneficial location for engaging the nostrils of an adult user with good positioning of the tips of the nasal members relative to the nasal valves of the nasal cavity.

[0022] Preferably, the second flare section is wider than the first flare section.

[0023] In some examples, the outer diameter of the first abutment zone at the end closest to the tip can have a diameter of 6.60-7.50 mm, optionally 6.90-7.20 mm, optionally 7.09 mm; and / or the outer diameter of the first abutment zone at the end furthest from the tip can have a diameter of 9.50-11.00 mm, optionally 9.75-10.50 mm, optionally 10.43 mm.

[0024] In some examples, the outer diameter of the second abutment zone at the end closest to the tip has a diameter of 10.50-11.50 mm, optionally 10.70-11.00 mm, optionally 10.70-10.90 mm, optionally 10.85 mm or 10.96 mm, and / or the outer diameter of the second abutment zone at the end furthest from the tip has a diameter of 11.00-20.00 mm, optionally 11.00-16.00 mm, optionally 11.00-15.00 mm, optionally 11.75-15.00 mm, optionally 14.00-15.00 mm, optionally 11.75 mm or 14.75 mm.

[0025] Preferably, the body includes a shoulder or convex section separating at least a portion of the first abutment zone from at least a portion of the second abutment zone. In some embodiments, the shoulder or convex section may overlap partially with the first abutment zone and / or the second abutment zone. In some examples, the shoulder or convex section may overlap fully or partially with the first flared section and / or the second flared section.

[0026] Providing a shoulder or convex section on the nasal members can beneficially allow the nasal members to be more compact, particularly in terms of shortening the longitudinal length of the nasal members. In addition, providing a shoulder or convex section allows the wider second abutment zone to be located closer to the tip of the nasal members than would be possible with a single taper nasal member. This can help prevent the tip of the nasal members from being over-inserted into the user's nostrils.

[0027] In some embodiments, the shoulder or convex section of the body is located between 5.0 mm and 10.0 mm longitudinally from the tip.

[0028] In some embodiments, the first flared section comprises a frusto-conical section and / or a concave section and / or a convex section, and / or the second section comprises a frusto-conical section and / or a concave section and / or a convex section. Either or both of the first abutment zone and the second abutment zone can be in the form of one or more frusto-conical sections. Either or both of the first abutment zone and the second abutment zone can be in the form of one or more concave sections. Either or both of the first abutment zone and the second abutment zone can be in the form of one or more convex sections. The frusto-conical section, the concave section and the convex section may be combined in the same nasal member.

[0029] In some embodiments, a longitudinal axis of the first flare section coincides with a longitudinal axis of the second flare section.

[0030] In some embodiments, the body further comprises a tip section comprising a distal end of the body and extending from the distal end to the first flared section, optionally the tip section being convex.

[0031] In some embodiments, for example when the nasal member is to be used as part of a nasal spray, the body further comprises one or more shoulders for engagement by one or more fingers, the one or more shoulders being located further from the tip than the second flared section.

[0032] Another embodiment of the present disclosure provides a nasal spray, nasal cannula, nebulizer or nasal dilator comprising the nasal member according to the above embodiment. In the case of a nasal spray, the device may be, for example, of the type used for nasal inhalation of medicines.

[0033] Another embodiment of the present disclosure is a method of using the nasal member of the first embodiment above, wherein in a first mode of use, the nasal member is inserted into a first nostril having a first range of sizes such that the first nostril abuts against a first abutment zone of the first flared section, and in a second mode of use, the nasal member is inserted into a second nostril having a second range of sizes such that the second nostril abuts against a second abutment zone of the second flared section.

[0034] The first nostril may be a nostril of a pediatric user and the second nostril may be a nostril of an adult user.

[0035] Another embodiment of the present disclosure provides a method of manufacturing the nasal member of the first embodiment above, the method including forming a body of the nasal member to have a tip, a first flared section extending longitudinally away from the tip, and a second flared section also extending longitudinally away from the tip, the first flared section being closer to the tip than the second flared section, the first flared section defining a first abutment zone for engaging a first nostril having a first range of sizes, the second flared section defining a second abutment zone for engaging a second nostril having a second range of sizes, the first abutment zone having a maximum flare angle greater than a maximum flare angle of the second abutment zone.

[0036] In some embodiments, the nasal members are formed as a unitary member, optionally formed by molding, preferably injection molding.

[0041] As used herein, the use of the singular includes the plural unless the context clearly dictates otherwise. As used herein, the use of "and / or" means "and" and "or" unless stated otherwise.

[0042] As used herein, the term "flare angle" means, with respect to a point on the outer surface of the nasal members, the angle between the longitudinal axis of the nasal members and a line tangent to the outer surface at that point, as shown, for example, in FIG.

[0043] The present disclosure relates generally to nasal elements, and further to nasal sprays, nasal cannulas, nebulizers or nasal dilators that include the nasal elements, as well as methods of using and manufacturing the nasal elements.

[0044] 1-7 show a nasal member 1 comprising a body 2 having a tip 3 for insertion into a user's nostril. As shown in FIG 1, the body 2 comprises a first flared section 10 that extends longitudinally away from the tip 3 and a second flared section 11 that also extends longitudinally away from the tip 3. The first flared section 10 is closer to the tip 3 than the second flared section 11.

[0045] The first flared section 10 defines a first abutment zone 20 for engaging a first nostril having a first range of sizes.

[0046] The second flared section 11 defines a second abutment zone 21 for engaging a second nostril having a second range of sizes.

For example, the flare angle can vary from a minimum flare angle of 15°-20° to a maximum flare angle of 35°-65°, preferably 40°-60°, and more preferably 58°.

[0052] Similarly, the flare angle of the second abutment zone 21 may be constant along the length of the second abutment zone 21. This may be the case, for example, when the second flared section 11 has a cone shape as shown, for example, in FIG. 8B. For example, the constant flare angle of the second abutment zone 21 may be 10°-30°, preferably 15°-25°, and more preferably 18°.

[0053] Alternatively, the flare angle of the second abutment zone 21 can vary along the length of the second abutment zone 21. This can be the case, for example, when the second flared section 11 has a concave configuration as shown, for example, in FIG. 8A. For example, the flare angle can vary from a minimum flare angle of 5°-10° to a maximum flare angle of 10°-30°, preferably 15°-25°, and more preferably 18°.

[0054] The longitudinal length of the first abutment zone 20 and / or the first flare section 10 may be less than the longitudinal length of the second abutment zone 21 and / or the second flare section 11 .

Measurements may be taken, for example, at 7.00 mm or 10.00 mm longitudinally from the tip 3, as shown in the example of FIG. 7. The outer diameter of the second abutment zone 21 at the end furthest from the tip 3 may have a diameter of 11.00 mm-20.00 mm, optionally 11.00 mm-16.00 mm, optionally 11.00 mm-15.00 mm, optionally 11.75 mm-15.00 mm, optionally 14.00 mm-15.00 mm, optionally 11.75 mm-14.75 mm.

[0059] The body 2 may comprise a shoulder or convex section 12 separating at least a portion of the first abutment zone 20 from at least a portion of the second abutment zone 21. The shoulder or convex section 12 of the body 2 may be located between 5.0 mm and 10.0 mm longitudinally from the tip 3. The shoulder or convex section 12 may partially overlap the first abutment zone 20 and / or the second abutment zone 21. Additionally or alternatively, the shoulder or convex section 12 may fully or partially overlap the first flared section 10 and / or the second flared section 11.

[0060] The first flare section 10 can include a frusto-conical section and / or a concave section and / or a convex section, and / or the second flare section 11 can include a frusto-conical section and / or a concave section and / or a convex section.

[0061] The longitudinal axis of the first flare section 10 may be coincident with the longitudinal axis of the second flare section 11, such as in the example of FIG.

[0062] The body 2 comprises a tip 3 of the body 2 and may further comprise a tip section 13 extending from the tip 3 to the first flared section 10, optionally the tip section 13 being convex as shown in Figures 1 and 3.

An example of a nasal spray 100 is shown in Figure 9, where the nasal member 1 is mounted on a body 102 of the nasal spray 100. In use, a source of product, for example a medicine to be delivered intranasally, may be contained within the body 102.

[0065] The nasal member 1 of the present disclosure can be used in a first mode of use in which the nasal member 1 is inserted into a first nostril having a first range of sizes such that the first nostril abuts against the first abutment zone 20 of the first flared section 10, and in a second mode of use in which the nasal member 1 is inserted into a second nostril having a second range of sizes such that the second nostril abuts against the second abutment zone 21 of the second flared section 11. For example, the first nostril can be the nostril of a pediatric user and the second nostril can be the nostril of an adult user.

[0066] The nasal member 1 of the present disclosure can be manufactured to be formed as a unitary member. The nasal member 1 can be formed, for example, by molding, preferably injection molding. [Industrial Applicability]
