Estimating the term…
The present disclosure relates to a visual alignment indicator for a nasal spray dispenser or an adapter for a nasal spray dispenser, and a nasal spray guide adapter for holding a nasal spray dispenser, including the visual alignment indicator, while dispensing a fluid product into a nostril of a user. A spray guide adapter for holding a nasal spray dispenser includes a lower end and an elongated upper end for dispensing the nasal spray fluid into a nostril of a user, the spray guide adapter includes a housing having a dispenser opening for inserting and holding the lower end of the nasal spray dispenser, and an alignment indicator configured for providing a user of the nasal spray dispenser with feedback on the orientation of the elongated upper end of the nasal spray dispenser in the nostril of the user.
An alignment indicator for a nasal spray dispenser, the nasal spray dispenser comprising a lower end and an elongated upper end for dispensing nasal spray fluid into a nostril of a user, the alignment indicator comprising at least two different visual elements configured for defining at least one line of sight for the user, thereby providing the user of the nasal spray dispenser with visual feedback on the orientation of the elongated upper end of the nasal spray dispenser in the nostril of the user, wherein a visual feedback is provided to the user when two of the visual elements are visually aligned to the user along one line of sight.
The alignment indicator according to any of the preceding claims, configured to be a front sight for the user while orienting the upper end of the nasal spray dispenser in the nostril while holding the dispenser.
The adapter according to any of the preceding claims, wherein at least one of the visual elements are located towards an upper part of the alignment indicator and at least one other and different visual element is located towards a lower part of the alignment indicator.
The alignment indicator according to any of the preceding claims, wherein the visual alignment indicator extends longitudinally between at least two different visual elements.
The alignment indicator according to any of the preceding claims, wherein the alignment indicator comprises a cross-hair pattern for visual guidance of the user.
The alignment indicator according to any of the preceding claims, wherein the alignment indicator comprises a cross-hair pattern with a first end and a second end separated by a distance, the first end is located towards a top surface of the adapter;
The alignment indicator according to any of the preceding claims, wherein the visual elements comprise at least one solid element and at least one hollow element.
The alignment indicator according to any of the preceding claims, wherein the visual elements comprise at least two solid elements and at least one hollow element.
The alignment indicator according to any of the preceding claims, wherein a visual feedback is provided when one of the visual elements, such as a solid visual element, is visible to the user through another of the visual elements, such as a hollow visual element.
The alignment indicator according to any of the preceding claims, wherein at least two of the different visual elements, such as a hollow element and a solid element, are separated along the line of sight and/or separated along a longitudinal axis defined by the nasal spray dispenser.
The alignment indicator according to 16, wherein the two different visual elements are separated by at least 10 mm, preferably by at least 20 mm, more preferably by at least 30, most preferably by at least 40 mm.
The alignment indicator according to any of the preceding claims, wherein the visual alignment indicator is configured for defining two different lines of sight for the user.
The alignment indicator according to any of the preceding claims, wherein the visual alignment indicator is configured for visually indicating a first correct orientation in the left nostril of the user and a second correct orientation in the right nostril of the user.
The alignment indicator according to any of the preceding claims, wherein the visual elements comprise at least two solid elements
The alignment indicator according to any of the preceding claims, wherein at least two of the visual elements, such as two solid elements or two hollow elements, are separated in a plane defined by a bottom end of the dispenser.
The alignment indicator according to any of the preceding claims, wherein the visual alignment indicator comprises an upper element and a lower element, preferably extending radially from the dispenser, and wherein the visual elements are formed in said elements.
The alignment indicator according to any of the preceding claims, wherein the line of sight is adjustable.
The alignment indicator according to any of the preceding claims, wherein the alignment indicator comprises a rotatable element defining two or more different lines of sight, such that the line of sight is adjustable.
The alignment indicator according to any of the preceding claims, wherein the alignment indicator is a tactile alignment indicator configured for providing a tactile feedback to the user, such as sound, and/or vibration.
The alignment indicator according to any of the preceding claims, wherein the alignment indicator forms an axis which is non-parallel with a longitudinal axis formed by the elongated upper end of the dispenser, such that said longitudinal axis forms an alignment angle with a line of sight of the alignment indicator.
The alignment indicator according to any of the preceding claims, wherein the alignment indicator comprises a light source, for example located at a bottom of the channel.
The alignment indicator according to any of the preceding claims, wherein a distance between two of the visual elements along the line of sight is less than 40 mm, such a less than 30 or less than 20 mm.
The alignment indicator according to any of the preceding claims, wherein the delivery angle of the fluid of the nasal spray dispenser can be adjusted by modifying the position of the alignment indicator.
The alignment indicator according to any of the preceding claims, comprising at least one sensor configured for providing a tactile signal, such as a sound and/or vibration, and/or a visual signal, when the adapter is within a predefined spatial orientation.
A nasal spray dispenser comprising a lower end and an elongated upper end for dispensing nasal spray fluid into a nostril of a user, the nasal spray dispenser comprising an alignment indicator as defined in any one of the preceding claims.
