Description

Folding Mask Inhaler

The present invention relates to an inhaler, and more specifically, to a mask-type foldable inhaler.

For patients with asthma and chronic obstructive lung disease (COPD), inhaler treatment is recommended as the standard first-line treatment. Over the past several decades, the types and uses of inhalers have become more complex, and the population with the disease is aging. However, most existing inhalers use a method in which the patient loads a drug cartridge into a plastic inhaler and inhales it through a reed. In this case, patients may take additional inhalations with their inhalers when their symptoms worsen, or they may receive a prescription for an extra inhaler from their doctor in case they leave their inhaler behind when going on a long business trip or trip or going to work. However, in cases where additional inhalations are made with the previously prescribed inhaler, there are cases where the prescribed inhaler runs out and the patient must visit the medical institution again for a prescription, and conversely, in cases where additional inhalations are not required much, there are many leftover inhalers that have passed their expiration date and must eventually be discarded.

The purpose of the present invention is to provide a foldable mask inhaler according to one embodiment that is foldable, making it easy to store and transport, and thus basically allowing for convenience of portability during long-term business trips, and allowing it to be provided separately from the inhaler used when additional use is required for symptom control. In addition, as a mask type, it is provided in the form of a foldable mask inhaler that is tighter than existing inhalers, allows better coordination between the hand motion for loading and fitting the mask to the mouth and the oral suction motion, and prevents the drug from spreading to the surroundings.

FIG. 1 illustrates one embodiment of a foldable mask inhaler (10), FIG. 2 illustrates a state in which a user is wearing the foldable mask inhaler (10) of FIG. 1, and FIGS. 3 and 4 illustrate one embodiment of a porous layer assembly (400', 400''), respectively.

Referring to FIGS. 1 and 2, the foldable mask inhaler (10) is a foldable and unfoldable mask-type inhaler for users with diseases requiring inhaler treatment, such as asthma or COPD, and may include a drug (D) on one side. The user can unfold the foldable mask inhaler (10), hang the hooks (300) on both ears (E), and inhale the drug (D) through the mouth.

In one embodiment, the foldable mask inhaler (10) may be an inhaler that inhales through the oral cavity rather than the nasal cavity. When the user wears the foldable mask inhaler (10), the lead (500) described below is positioned to correspond to the user's mouth, and the user can inhale the lead (500) through the oral cavity.

In one embodiment, when a user is wearing the foldable mask inhaler (10), a portion of the foldable mask inhaler (10) may cover the user's nose. For example, a portion of the foldable mask inhaler (10) (e.g., the frame (100) and the cover (200)) may be arranged to cover the mouth and nose. Accordingly, when a user is wearing the foldable mask inhaler (10), the user may breathe through the mouth, but both the user's mouth and nasal cavity may be protected by the foldable mask inhaler (10). In one embodiment, the foldable mask inhaler (10) may include a frame (100), a cover (200), a ring (300), a porous layer assembly (400), a reed (500), a protective member (600), and a packaging container (700).

The frame (100) forms the shape of the foldable mask inhaler (10) and supports other components. The frame (100) can be folded and unfolded, and in one embodiment, a plurality of wires can be connected to each other. As shown in FIG. 1, when the foldable mask inhaler (10) is folded, the frame (100) can maintain a folded state based on a central axis in one direction (the X-axis direction of FIG. 1). Thereafter, when a user grabs a pair of rings (300) and unfolds the frame (100), the frame (100) can be unfolded as shown in FIG. 2.

In one embodiment, the frame (100) may include a horizontal portion (110) extending parallel in one direction in an unfolded state and a pair of inclined portions (120) extending outwardly from both ends of the horizontal portion (110). Accordingly, as shown in FIG. 2, the horizontal portion (110) may be arranged to face the front of the user's head (H), and the pair of inclined portions (120) may extend toward a pair of the user's ears (E). When the frame (100) is folded, a portion of the horizontal portion (110) may extend parallel to one of the pair of inclined portions (120), and a remaining portion of the horizontal portion (110) may extend parallel to the remaining one of the pair of inclined portions (120), so as to be arranged in a V shape as shown in FIG. 1. Alternatively, the frame (100) may be folded so that the entire horizontal portion (110) extends parallel to one inclined portion (120), so that one inclined portion (120) has a longer V shape.

As an example, as shown in Fig. 2, when the user is wearing the foldable mask inhaler (10), the lid (500) described below may be positioned to correspond to the user's mouth. Alternatively, the frame (100) and cover (200) of the foldable mask inhaler (10) may be positioned to cover both the user's mouth and nose like a conventional mask, thereby protecting the user's oral cavity and nasal cavity.

Although only the frame (100) viewed from a plane is shown in FIG. 1 and FIG. 2, a plurality of frames (100) may be arranged in a direction perpendicular to the plane (height direction). In one embodiment, the frame (100) may include a plurality of wires in the height direction. The number of wires is not particularly limited, and may be provided in two or three or more in consideration of the size of the user's face or the size of the lead (500). In addition, the type of wire included in the frame (100) is not particularly limited, and may be a thin metal wire that can be easily bent or stretched even with a light force.

The cover (200) is arranged on at least one side of the frame (100) to block external foreign substances when the user inhales through the foldable mask inhaler (10). In one embodiment, the cover (200) may be made of cotton or polypropylene non-woven fabric frequently used in disposable masks. The cover (200) includes a grid structure having a predetermined interval or includes a separate dust collection filter to prevent external foreign substances from entering the user's oral cavity when the user inhales.

The cover (200) may be arranged to cover the entire frame (100) or may be arranged on a portion of the frame (100) to cover an area where the drug (D) is contained or a lead (500). In one embodiment, as shown in FIG. 1, the cover (200) may be arranged on the front and rear sides of the frame (100), respectively. In one embodiment, the cover (200) may be arranged on a horizontal portion (110) of the frame (100).

In one embodiment, when a user puts on the foldable mask inhaler (10), a cover (200) may be placed on the side facing the user's face, and a cover (200) may also be placed on the opposite side. Alternatively, the cover (200) may be placed only on the front or rear of the frame (100). In one embodiment, the cover (200) may be placed on the front of the frame (100) so that the frame (100) is not exposed to the outside.

The rings (300) are arranged at each end of the frame (100) and are connected to the user's ears (E), etc., to secure the foldable mask inhaler (10). Alternatively, the user may hold a pair of rings (300) and unfold the foldable mask inhaler (10) when unfolding it. The rings (300) are arranged at each end of the inclined portion (120) and may be circular or oval in shape. The material of the rings (300) may be synthetic resin, cotton, thin metal wire, etc.

The porous layer assembly (400) is arranged on one side of the foldable mask inhaler (10). As an example, as shown in FIG. 2, the porous layer assembly (400) may be arranged on the inside of the frame (100) so as to face the user's face. The porous layer assembly (400) causes the drug (D) moving by the flow of air when the user inhales to be crushed into small particles, thereby preventing the user from directly inhaling excessively large particles of the drug (D). In addition, the porous layer assembly (400) may serve to filter out foreign substances that may be included in the drug (D). For example, the drug (D) may be crushed into particles of 10 μm or less or 2 μm or less and introduced into the user's mouth through the inhalation port (510). In addition, the drug (D) may include particles of different sizes.

In one embodiment, the porous layer assembly (400) is arranged on the inside of the lid (500), and both ends are connected to a pair of inclined portions (120) in one direction, and a drug (D) can be arranged on the inside. Accordingly, when the user inhales, the drug (D) passes through the porous layer assembly (400) and is crushed into small particles, and then can be introduced into the user's oral cavity through the inhalation port (510) of the lid (500).

In one embodiment, the porous layer assembly (400) may be made of a material that can be folded and unfolded in the same manner as the frame (100) is folded and unfolded.

In one embodiment, the porous layer assembly (400) includes a plurality of porous layers, each of which may include pores. The plurality of porous layers are arranged at a predetermined interval in one direction (the Y-axis direction of FIG. 2), and each of which may include pores of different sizes.

In one embodiment, the porous layer assembly (400) may be located at a shorter distance from the drug (D) than from the suction port (510). This configuration allows the drug (D) to form a sufficient vortex as it flows through the porous layer assembly (400) to the suction port (510).

As shown in FIG. 3, the porous layer assembly (400') may include four different porous layers. The first porous layer (410') is a porous layer that is arranged closest to the drug (D) and may include pores (P) having the smallest size. The second porous layer (420') is arranged on the first porous layer (410') at a predetermined distance from it and may have pores (P) having a larger size than the pores (P) of the first porous layer (410'). In addition, a third porous layer (430') and a fourth porous layer (440') may be arranged sequentially thereon at similar predetermined distances. In addition, the third porous layer (430') may have pores (P) larger in size than the pores (P) of the second porous layer (420'), and the fourth porous layer (440') may have pores (P) larger in size than the pores (P) of the third porous layer (430'). Accordingly, when a user inhales while wearing the foldable mask inhaler (10), the drug (D) is dispersed into small particles while sequentially passing through the first porous layer (410'), the second porous layer (420'), the third porous layer (430'), and the fourth porous layer (440'), and the large particles are filtered out and then can be introduced into the user's oral cavity.

In one embodiment, the plurality of porous layers may be circular, elliptical, or polygonal. In addition, the plurality of porous layers may have the same size and shape, or different sizes and shapes. In addition, the plurality of porous layers may be spaced apart from each other at the same interval, or spaced apart from each other at different intervals.

In one embodiment, the porous layer assembly (400') may include a support (450'). The support (450') supports a plurality of porous layers. The support (450') may have a shape corresponding to the shape of the porous layers. In one embodiment, the support (450') may have a columnar shape having a circular, elliptical, or polygonal cross-section. Here, the support (450') may include a mesh or pores through which the drug (D) may flow. Alternatively, the support (450') may have all sides closed. Alternatively, the support (450') may have a linear rod shape and may be arranged on at least one side of the plurality of layers. In addition, the support (450') may also be made of a material that can be folded and unfolded.

As an example, as shown in FIG. 4, the porous layer assembly (400'') may include a first porous layer (410''), a second porous layer (420''), a third porous layer (430''), a fourth porous layer (440''), and a support (450''). The first porous layer (410''), the second porous layer (420''), the third porous layer (430''), the fourth porous layer (440''), and the support (450'') may have the same configuration as the first porous layer (410'), the second porous layer (420'), the third porous layer (430'), the fourth porous layer (440'), and the support (450') of the porous layer assembly (400') described above, and only the pores (P) may be different. More specifically, as shown in FIG. 4, the porous layer assembly (400'') can include pores (P) of different sizes in one porous layer. Therefore, it is easy to form a vortex within the porous layer assembly (400''), and large particles of the drug (D) are easily crushed into small particles while flowing within the multiple porous layers.

In one embodiment, the porous layer assembly (400) may be supported on the inside of the lead (500) in one direction (the X-axis direction of FIG. 2). Additionally, the porous layer assembly (400) may be positioned closer to the drug (D) than the suction port (510) of the lead (500).

In one embodiment, the porous layer assembly (400) may include two, three, five or more porous layers.

The lead (500) is arranged on one side of the frame (100) and is a part through which the user breathes directly through the mouth when wearing the foldable mask inhaler (10). As shown in Fig. 1, when the foldable mask inhaler (10) is folded, the lead (500) can also be maintained in a folded state. Then, when the user unfolds the foldable mask inhaler (10), it unfolds as shown in Fig. 2, and when the user hangs a pair of rings (300) on the ears (E), the inhalation port (510) can come into contact with the user's mouth. The user can inhale the drug (D) while breathing through the mouth.

In one embodiment, the lead (500) can accommodate a drug (D). The drug (D) is a drug used for inhalation diseases, and can be a beta-adrenergic drug, an anticholinergic, a leukotriene modifier, a mast cell stabilizer, a corticosteroid, an immunomodulator, a methylxanthine, or other drugs used for preventing or treating asthma and COPD exacerbation in the form of a dry powder. The drug (D) can be accommodated in the lead (500) located on the opposite side of the user's face. In one embodiment, as shown in FIG. 2, the drug (D) can be accommodated on the inner side of the lead (500) corresponding to the horizontal portion (110) of the frame (100).

In one embodiment, the lead (500) may be polygonal when viewed in a plan view. As shown in FIG. 2, the lead (500) may have a hexagonal cross-section. The lead (500) includes a plurality of wires or plates, some of which may be supported by the frame (100) or the cover (200). One of the plurality of wires or plates included in the lead (500) may be arranged to correspond to the horizontal portion (110) of the frame (100), and a pair of wires or plates extending from both ends thereof may be arranged on the inner side of a pair of inclined portions (120), respectively. And the remaining wires or plates may extend toward the user's face and form a suction port (510) corresponding to the user's mouth.

In one embodiment, the lead (500) may include a porous layer assembly (400) therein. As shown in FIG. 2, the porous layer assembly (400) may be positioned on the user side of the frame (100) such that a drug (D) is accommodated therebetween.

In one embodiment, the lead (500) may include an inlet (510). As shown in FIG. 2, the inlet (510) is positioned toward the user's face and may be circular or oval in shape. When the user wears the foldable mask inhaler (10), the inlet (510) may be positioned to correspond to the user's mouth. When the user breathes, the drug (D) contained therein may be moved by the airflow and introduced into the user's mouth.

In one embodiment, the lead (500) may be made of a foldable material.

The protective member (600) is arranged to cover or wrap the drug (D) and prevent the drug (D) from leaking before using the foldable mask inhaler (10). As shown in FIGS. 1 and 2, the protective member (600) may be arranged on the inside of the lid (500) to face the inhalation port (510). The protective member (600) is made of a thin film or the like and may be packaged in a PTP (Press Through Package) manner used for packaging pills and the like. In one embodiment, the protective member (600) is an aluminum thin film, and when the user unfolds the foldable mask inhaler (10), at least a portion thereof may be ruptured or torn, thereby exposing the drug (D) to be able to move to the outside. In this state, when the user breathes, the drug (D) may flow toward the mouth by the air. The protective member (600) may include the entire drug (D) or may be arranged only on a surface facing the user's face.

The packaging container (700) is used to store and transport the foldable mask inhaler (10) when it is not in use. In one embodiment, the foldable mask inhaler (10) can be accommodated in the packaging container (700) in a folded state. The packaging container (700) is made of paper or vinyl as a disposable or reusable device and may include a zipper on one side. The user can tear off one side of the packaging container (700), take out the foldable mask inhaler (10), and then unfold it to use it. Thereafter, the user can discard the packaging container (700) or store the foldable mask inhaler (10) that has completed use of the drug (D) back into the packaging container (700), and if the lid (500) is removed, it can be reused as a mask, i.e., a general face and airway protection mask. That is, the lead (500) can be detachably attached to the frame (100) and/or the cover (200), and this applies equally to the foldable mask inhalers (10A, 10B, 10C, 10D, 10E, 10F) according to all embodiments below.

In one embodiment, the foldable mask inhaler (10) may include a frame (100), a cover (200), a ring (300), a lid (500), and a drug (D). Alternatively, the foldable mask inhaler (10) may include a frame (100), a cover (200), a ring (300), a porous layer assembly (400), a lid (500), and a drug (D). Alternatively, the foldable mask inhaler (10) may include a frame (100), a cover (200), a ring (300), a porous layer assembly (400), a lid (500), a drug (D), a protective member (600), and a packaging container (700).

FIG. 5 shows another embodiment of a foldable mask inhaler (10A), and FIG. 6 shows an enlarged view of the porous layer assembly (400A) and the lid (500A) of FIG. 5.

The foldable mask inhaler (10A) according to the present embodiment may have different configurations of the porous layer assembly (400A) and the lid (500A) compared to the foldable mask inhaler (10) according to the above-described embodiment. The remaining configurations of the foldable mask inhaler (10A) may be the same as those of the foldable mask inhaler (10), and a detailed description thereof will be omitted.

The frame (100A), the cover (200A), the ring (300A), and the drug (D), the protective member (600A) may be the same as the frame (100), the cover (200), the ring (300), and the drug (D), the protective member (600), and a detailed description thereof is omitted.

As shown in Fig. 5, the lead (500A) may be placed on the side of the frame (100A) facing the user's face. In addition, only a part of the lead (500A) may be in contact with the frame (100A) or the cover (200A), and the remaining part may not be in contact with other components of the foldable mask inhaler (10A). In addition, a drug (D) may be accommodated on the inside of the lead (500A). The drug (D) may be covered by a protective member (600A).

In one embodiment, the lead (500A) may include an intake port (510A), a support portion (520A), a first extension portion (530A), and a second extension portion (540A).

As shown in Fig. 6, the suction port (510A) is positioned adjacent to the user's face, and the support member (520A) is positioned on the opposite side of the suction port (510A). The support member (520A) may be positioned on the inside of the frame (100A) or the cover (200A). In addition, the support member (520A) may support the porous layer assembly (400A).

The first extension portion (530A) may be provided in pairs so as to be spaced apart from each other at both ends of the support portion (520A). In addition, the second extension portion (540A) may be provided in pairs so as to be close to each other at both ends of the first extension portion (530A). A suction port (510A) may be arranged between the pair of second extension portions (540A). Accordingly, as shown in FIGS. 5 and 6, the lead (500A) may be hexagonal overall.

In one embodiment, the first extension portion (530A) and the second extension portion (540A) do not contact the porous layer assembly (400A) and may include a gap therebetween. Accordingly, a portion of the drug (D) flowing as the user breathes may move through the space between the first extension portion (530A) and the second extension portion (540A) and the porous layer assembly (400A).

In one embodiment, a pair of second extensions (540A) may be extended so that the gap between them gradually becomes narrower. Accordingly, a vortex is formed when the flow of the drug (D) comes into contact with the inner side of the second extension (540A). Accordingly, the drug (D) with large particles gathers on the inner side of the second extension (540A), and the drug (D) with small particles can move to the user's mouth through the inhalation port (510A). Here, large particles mean 10 ㎛ or more or 2 ㎛ or more, and small particles mean 10 ㎛ or less or 2 ㎛ or less.

In one embodiment, the inclination of the second extension portion (540A) may be 30 degrees or more and 70 degrees or less with respect to the horizontal line. If the inclination of the second extension portion (540A) is less than 30 degrees, the gap between the second extension portion (540A) and the porous layer assembly (400A) may become too narrow, so that the flow of the drug (D) may not be smooth. In addition, if the inclination of the second extension portion (540A) exceeds 70 degrees, almost no eddy current may occur, so that large particles of the drug (D) may be directly introduced into the suction port (510A). In one embodiment, the inclination of the second extension portion (540A) may be 40 degrees or more and 60 degrees or less.

In one embodiment, the lead (500A) may include a vortex region (550A) and a suction region (560A). As shown in FIG. 6, the vortex region (550A) may be formed inside a pair of second extensions (540A). As described above, since the pair of second extensions (540A) have a shape that extends to come closer to each other, the flow of the drug (D) forms a vortex when it collides with the pair of second extensions (540A). Due to the vortex, large particles may accumulate in the vortex region (550A) and may not move to the suction port (510A) or may move only a minimal amount. In addition, the suction region (560A) may be formed inside the suction port (510A). Small particles of drug (D) that pass through the vortex region (550A) can flow into the suction port (510A) through the suction region (560A).

In one embodiment, the lead (500A) may be hexagonal overall.

The porous layer assembly (400A) may be placed on the inner side of the lead (500A). As shown in FIGS. 5 and 6, one side of the porous layer assembly (400A) may be placed on the support portion (520A) of the lead (500A). Additionally, the drug (D) may be placed on the lower side of the porous layer assembly (400A).

In one embodiment, a porous layer assembly (400A) may include a first porous layer (410A), a second porous layer (420A), a third porous layer (430A), a fourth porous layer (440A), and a support (450A).

The first porous layer (410A) is arranged closest to the support member (520A) and may be arranged in contact with or very close to the drug (D). In one embodiment, the first porous layer (410) may be arranged in contact with or adjacent to a protective member (600A) covering the drug (D). The second porous layer (420A), the third porous layer (430A), and the fourth porous layer (440A) may be sequentially arranged at a predetermined interval on the first porous layer (410A). In addition, the first porous layer (410A), the second porous layer (420A), the third porous layer (430A), and the fourth porous layer (440A) may include pores having the same or different sizes.

The support (450A) supports the first porous layer (410A), the second porous layer (420A), the third porous layer (430A), and the fourth porous layer (440A), and may have a columnar shape having a cross-section of a circle, an ellipse, or a polygon. Alternatively, the support (450A) may be one or more straight rods. In one embodiment, the support (450A) is a plurality of rods, or a column including a mesh or a void, such that when the user breathes, a portion of the drug (D) may move through the space between the supports (450A) or the mesh or the void.

In one embodiment, the porous layer assembly (400A) may be generally rectangular.

In one embodiment, the porous layer assembly (400A) may be in contact with the support portion (520A) of the lead (500A) and may not be in contact with other portions of the lead (500A). As shown in FIG. 6, the porous layer assembly (400A) may have a length smaller than the support portion (520A) in one direction (the X-axis direction of FIG. 6).

In one embodiment, the porous layer assembly (400A) may be shorter in distance from the drug (D) than from the suction port (510A). This configuration allows the drug (D) to form a sufficient vortex while flowing through the porous layer assembly (400A) to the suction port (510A). More specifically, the distance between the first porous layer (410A) and the drug (D) may be shorter than the distance between the fourth porous layer (440A) and the suction port (510A).

When a user breathes while wearing the foldable mask inhaler (10A), a portion of the drug (D) may pass through the plurality of porous layers and then move to the inhalation area (560A) through the vortex region (550A). And a portion of the drug (D) may pass through some of the plurality of porous layers and then exit the porous layer assembly (400A) and move to the inhalation area (560A) through the vortex region (550A).

In one embodiment, the porous layer assembly (400A) and the lead (500A) can be configured to be foldable.

FIG. 7 shows another embodiment of a foldable mask inhaler (10B), and FIG. 8 shows an enlarged view of the porous layer assembly (400B) and the lid (500B) of FIG. 7.

The foldable mask inhaler (10B) according to the present embodiment may have different configurations of the porous layer assembly (400B) and the lid (500B) compared to the foldable mask inhaler (10) according to the above-described embodiment. The remaining configurations of the foldable mask inhaler (10B) may be the same as those of the foldable mask inhaler (10), and a detailed description thereof will be omitted.

In one embodiment, a foldable mask inhaler (10B) may include a frame (100B), a cover (200B), a ring (300B), a porous layer assembly (400B), a lid (500B), a drug (D), a protective member (600B), and a packaging container (not shown).

The frame (100B), the cover (200B), the ring (300B), and the drug (D), the protective member (600B) may be the same as the frame (100), the cover (200), the ring (300), and the drug (D), the protective member (600), and a detailed description thereof is omitted.

As shown in Fig. 7, the lead (500B) may be placed on the side of the frame (100B) facing the user's face. In addition, only a part of the lead (500B) may contact the frame (100B) or the cover (200B), and the remaining part may not contact other components of the foldable mask inhaler (10B). In addition, a drug (D) may be accommodated on the inside of the lead (500B). The drug (D) may be covered by the protective member (600B).

In one embodiment, the lead (500B) may include an intake port (510B) and a support member (520B).

As shown in FIG. 8, the suction port (510B) is arranged adjacent to the user's face, and the support portion (520B) may be a plurality of plates that extend in one direction (the Y-axis direction of FIG. 8). The plurality of support portions (520B) may have a folding screen shape in which the edges are connected to each other and both ends are rolled up overall. More specifically, the cross-sectional outline of the lead (500B) may extend in a zigzag manner alternately toward the inside and the outside of the lead (500B). That is, the plurality of support portions (520B) may be arranged such that the cross-section forms a closed contour, and the angles between adjacent support portions (520B) are alternately acute and obtuse.

This structure can increase the eddy current of the drug (D) flow, thereby causing the drug (D) particles to be crushed into smaller particles, and can prevent large particles of the drug (D) from being maintained on the inside of the support (520B) and moving to the suction port (510B).

In one embodiment, one end of the support member (520B) may be in contact with the inside of the frame (100B) or cover (200B), and the other end may form a suction port (510B).

In one embodiment, the lead (500B) may include a vortex region (550B) and a suction region (560B). As illustrated in FIG. 8, the vortex region (550B) may be disposed above the porous layer assembly (400B) and formed on an inner surface of the lead (500B). Due to the vortex formed while passing through the porous layer assembly (400B) and the vortex formed by the plurality of supports (520B) connected to each other in a zigzag manner, large particles of the drug (D) may accumulate in the vortex region (550B) and may not move to the suction port (510B) or may move only a minimal amount. Additionally, the suction region (560B) may be formed on the inner surface of the suction port (510B). Small particles of drug (D) that pass through the vortex region (550B) can flow into the suction port (510B) through the suction region (560B).

In one embodiment, a portion of the support member (520B) positioned above the porous layer assembly (400B) among the support members (520B) may be extended and tilted so as to gather inward. Accordingly, the eddy formed by the flow of the drug (D) may be increased.

The porous layer assembly (400B) may be arranged on the inner side of the lid (500B). As shown in FIGS. 7 and 8, the porous layer assembly (400B) is provided to include a plurality of porous layers on the inner side of the lid (500B) and may be arranged adjacent to the drug (D). In one embodiment, the porous layer assembly (400B) may include a first porous layer (410B), a second porous layer (420B), a third porous layer (430B), a fourth porous layer (440B), and a support (450B). The first porous layer (410B) may be arranged adjacent to the drug (D) and a protective member (600B) enclosing the drug (D), and may include a pore (P) of a predetermined size. The second porous layer (420B), the third porous layer (430B), and the fourth porous layer (440B) are sequentially arranged at predetermined intervals on top of the first porous layer (410B) and may include pores (P) of different sizes or the same size.

In one embodiment, the porous layer assembly (400B) may be located at a shorter distance from the drug (D) than from the suction port (510B). This configuration allows the drug (D) to form a sufficient vortex while flowing through the porous layer assembly (400B) to the suction port (510B).

In one embodiment, the plurality of porous layers are supported on the support (520B) and may not include a separate support. In one embodiment, the plurality of porous layers may be arranged without clearance with the inner surface of the support (520B).

When a user breathes while wearing a foldable mask inhaler (10A), the drug (D) can pass through multiple porous layers and then move to the inhalation area (560B) through the vortex area (550B).

In one embodiment, the porous layer assembly (400B) and the lead (500B) can be configured to be foldable.

Fig. 9 shows another embodiment of a foldable mask inhaler (10C), and Fig. 10 shows an enlarged view of the lead (500C) of Fig. 9.

The foldable mask inhaler (10C) according to the present embodiment may have a different configuration of the lead (500C) compared to the foldable mask inhaler (10) according to the above-described embodiment. The remaining configuration of the foldable mask inhaler (10C) may be the same as that of the foldable mask inhaler (10), and a detailed description thereof will be omitted.

In one embodiment, the foldable mask inhaler (10C) may include a frame (100C), a cover (200C), a ring (300C), and a lead (500C), a drug (D), a protective member (600C), and a packaging container (not shown). Additionally, the foldable mask inhaler (10C) may not include a porous layer assembly.

The frame (100C), the cover (200C), the ring (300C), and the drug (D), the protective member (600C) may be the same as the frame (100), the cover (200), the ring (300), and the drug (D), the protective member (600), and a detailed description thereof is omitted.

As shown in Fig. 9, the lead (500C) may be placed on the side of the frame (100C) facing the user's face. In addition, only a part of the lead (500C) may be in contact with the frame (100C) or the cover (200C), and the remaining part may not be in contact with other components of the foldable mask inhaler (10C). In addition, a drug (D) may be accommodated on the inside of the lead (500C). The drug (D) may be covered by a protective member (600C).

In one embodiment, the lead (500C) may include a suction port (510C), a support member (520C), a first extension member (530C), a second extension member (540C), and a protruding member (570C).

As shown in Fig. 10, the suction port (510C) is positioned adjacent to the user's face, and the support portion (520C) is positioned to face the suction port (510C). In addition, the support portion (520C) has a shape corresponding to the inner surface of the frame (100C) or the cover (200C), and may be deformable according to an external force. As an example, as shown in Fig. 9, the support portion (520C) may have a flat shape, or as shown in Fig. 10, the support portion may have a curved shape.

The first extension part (530C) and the second extension part (540C) are respectively arranged between the suction port (510C) and the support part (520C), and may have shapes that are asymmetrical to each other. In one embodiment, the suction port (510C) may be arranged spaced apart from the central axis of the support part (520C). In addition, the first extension part (530C) may be concavely extended inwardly to have a greater curvature, and the second extension part (540C) may be concavely extended inwardly to have a smaller curvature than the first extension part (530C). Accordingly, as shown in FIG. 10, the lead (500C) has a shape that is distorted to one side, and this shape may increase the eddy current of the drug (D). The drug (D) may be arranged inwardly of the support part (520C) and covered by the protective member (600C).

A plurality of protruding members (570C) are arranged on the inner surface of the lead (500C) and extend inwardly by a predetermined length. As shown in FIG. 10, the protruding members (570C) have different lengths and can protrude from the inner surfaces of the first extension portion (530C) and the second extension portion (540C). The protruding members (570C) can increase eddy currents in the flow of the drug (D). Accordingly, the drug (D) having large particles can be crushed into small particles as it passes through the protruding members (570C). In addition, the drug (D) having large particles can be maintained between the protruding members (570C), and the drug (D) having small particles can move to the suction port (510C).

In one embodiment, the lead (500C) may be configured to be foldable.

Fig. 11 shows another embodiment of a foldable mask inhaler (10D), and Fig. 12 shows an enlarged view of the lead (500D) of Fig. 11.

The foldable mask inhaler (10D) according to the present embodiment may have a different configuration of the lead (500D) compared to the foldable mask inhaler (10) according to the above-described embodiment. The remaining configuration of the foldable mask inhaler (10D) may be the same as that of the foldable mask inhaler (10), and a detailed description thereof will be omitted.

In one embodiment, the foldable mask inhaler (10D) may include a frame (100D), a cover (200D), a ring (300D), and a lead (500D), a drug (D), a protective member (600D), and a packaging container (not shown). Additionally, the foldable mask inhaler (10D) may not include a porous layer assembly.

The frame (100D), cover (200D), ring (300D), and drug (D) and protective member (600D) may be the same as the frame (100), cover (200), ring (300), and drug (D) and protective member (600), and a detailed description thereof is omitted.

As shown in Fig. 11, the lead (500D) may be placed on the side of the frame (100D) facing the user's face. In addition, only a part of the lead (500D) may be in contact with the frame (100D) or the cover (200D), and the remaining part may not be in contact with other components of the foldable mask inhaler (10D). In addition, a drug (D) may be accommodated on the inside of the lead (500D). The drug (D) may be covered by a protective member (600D).

In one embodiment, the lead (500D) may include a suction port (510D), a support member (520D), a first extension member (530D), and a protruding member (570D).

As shown in Fig. 12, the suction port (510D) is positioned adjacent to the user's face, and the support member (520D) is positioned to face the suction port (510D). In addition, the support member (520D) may have a shape corresponding to the inner surface of the frame (100D) or the cover (200D).

The first extension portion (530D) extends between the suction port (510C) and the support portion (520C) and forms a side wall of the lead (500D). The suction port (510C) is arranged coaxially with the support portion (520C), and the first extension portion (530D) can be extended to converge inwardly toward the suction port (510D). Accordingly, as shown in FIG. 12, the lead (500D) has a frusto-conical shape, and this shape can increase the vortex of the drug (D). The drug (D) can be arranged on the inner side of the support portion (520D) and covered by the protective member (600D).

The protruding member (570D) may extend in a spiral shape along the inner surface of the lead (500D). As shown in FIG. 12, the protruding member (570D) may start from the lower end of the first extension portion (530D) where the drug (D) is positioned and may extend in a spiral shape toward the suction port (510D) along the central axis of the lead (500D). The other end of the protruding member (570) may be arranged on one side of the first extension portion (530D) adjacent to the suction port (510D). The protruding member (570D) may increase a vortex in the flow of the drug (D). Accordingly, the drug (D) having large particles may be pulverized into small particles as it passes through the protruding member (570D). In addition, the drug (D) having large particles may be maintained between the protruding members (570D), and the drug (D) having small particles may move to the suction port (510D).

In one embodiment, the lead (500D) may be configured to be foldable.

Fig. 13 shows another embodiment of a foldable mask inhaler (10E).

The foldable mask inhaler (10E) according to the present embodiment may have a different configuration of the lead (500E) compared to the foldable mask inhaler (10) according to the above-described embodiment. The remaining configuration of the foldable mask inhaler (10E) may be the same as that of the foldable mask inhaler (10), and a detailed description thereof will be omitted.

In one embodiment, the foldable mask inhaler (10E) may include a frame (100E), a cover (200E), a ring (300E), and a lead (500E), a drug (D), a protective member (600E), and a packaging container (not shown). Additionally, the foldable mask inhaler (10E) may not include a porous layer assembly.

The frame (100E), the cover (200E), the ring (300E), and the drug (D), the protective member (600E) may be the same as the frame (100), the cover (200), the ring (300), and the drug (D), the protective member (600), and a detailed description thereof is omitted.

As shown in Fig. 13, the lead (500E) can be placed on the side of the frame (100E) facing the user's face. One end of the lead (500E) can be in contact with the drug (D) covered by the protective member (600E), and the other end can be placed facing the user's face. The lead (500E) can be a cigarette-shaped rolled thin film of paper or a similar material. When the user unfolds the foldable mask inhaler (10E), the protective member (600E) ruptures, and when the user puts the lead (500E) in his mouth and inhales, the drug (D) can flow.

As an example, as shown in FIG. 14, the lead (500E-1) may have a cylindrical shape overall by rolling up the support (520E-1) and may have a constant cross-sectional area along the longitudinal direction. In addition, the lead (500E-1) may include a plurality of protruding members (570E-1) arranged toward the center on the inner surface. When a user puts the lead (500E-1) in his/her mouth and inhales, the drug (D) moves along the circular path formed by the support (520E-1) along the longitudinal direction of the lead (500E-1) toward the inhalation port (510E-1). In this process, the drug (D) may be pulverized into small particles when it collides with the support (520E-1).

In one embodiment, a plurality of protruding members (570E-1) may extend from one surface of the support member (520E-1) toward the center of the lead (500E-1). The length of the protruding members (570E-1) may form a gap with the adjacent support member (520E-1) so as not to excessively impede the flow of the drug (D). As the drug (D) moves along the inner surface of the support member (520E-1) and comes into contact with the protruding members (570E-1), the eddy current increases, and large particles of the drug (D) may be more easily pulverized. In one embodiment, the protruding members (570E-1) may be more densely packed on the support member (520E-1) disposed radially outer. As shown in Fig. 14, the protruding members (570E-1) are arranged somewhat sparsely on the support member (520E-1) arranged in the center, and a greater number of the protruding members (570E-1) can be concentrated on the support member (520E-1) arranged radially outward. Thanks to this arrangement, the large particles of drug (D) concentrated radially outward can be more easily crushed into small particles, and the small particles of drug (D) can be easily moved to the inlet (510E-1).

As an example, as shown in FIG. 15, the lead (500E-2) may have a shape in which the support member (520E-2) is rolled up to form an overall cylindrical shape, but the cross-sectional area thereof changes along the longitudinal direction. In addition, the lead (500E-2) may include a plurality of protruding members (570E-2) arranged toward the center on the inner surface. As an example, the lead (500E-2) may have a shape in which the cross-sectional area thereof gradually increases along the longitudinal direction from an end positioned opposite to the suction port (510E-2), and gradually decreases along the longitudinal direction toward the suction port (510E-2) at one point. Therefore, the lead (500E-2) may have an overall shape in which one side is convexly protruded, and the support member (520E-2) may have an asymmetrically rolled shape. As shown in Fig. 15, the cross-section of the lead (500E-2) may be an elliptical shape that is long in one direction, similar to the rings of a tree, and the spacing between the supports (520E-2) may also be formed to be longer in one direction. Thanks to this shape, when a user inhales the drug (D), the eddy current in the flow of the drug (D) is increased, so that large particles of the drug (D) are better pulverized and maintained on the inner surface of the supports (520E-2).

In one embodiment, a plurality of protruding members (570E-2) may extend from one surface of the support member (520E-2) toward the center of the lead (500E-2). The length of the protruding members (570E-2) may form a gap with the adjacent support member (520E-2) so as not to excessively impede the flow of the drug (D). In one embodiment, the length of the protruding members (570E-2) may vary depending on the distance between the adjacent support members (520E-2). The protruding members (570E-2) arranged in an area where the distance between the support members (520E-2) is far may have a longer length, and the protruding members (570E-2) arranged in an area where the distance between the support members (520E-2) is short may have a shorter length.

As the drug (D) moves along the inner surface of the support (520E-2) and comes into contact with the protruding member (570E-2), the eddy current increases, and the large particle drug (D) can be more easily crushed. In one embodiment, the protruding members (570E-2) can be more densely packed on the support member (520E-2) disposed radially outward. As shown in FIG. 15, the protruding members (570E-2) are somewhat sparsely packed on the support member (520E-2) disposed at the center, and a greater number of protruding members (570E-2) can be concentrated on the support member (520E-2) disposed radially outward. Due to this arrangement, the large particle drug (D) concentrated on the radially outward can be more easily crushed into small particles, and the small particle drug (D) can be easily moved to the inlet (510E-2).

In one embodiment, as shown in FIG. 16, the lead (500E-3) may have a layered structure in which a plurality of support members (520E-3) are stacked in the height direction. The plurality of support members (520E-3) may have cylindrical shapes with different diameters and may be arranged concentrically. In addition, the plurality of support members (520E-3) may be connected to each other so that the drug (D) may flow. In one embodiment, the support member (520E-3) having the largest diameter may be arranged at the bottom, on the opposite side of the suction port (510E-3). The support members (520E-3) are stacked in order of decreasing diameters above that, and the suction port (510E-3) may be formed on the inside of the support member (520E-3) having the smallest diameter.

In one embodiment, the lead (500E-3) may have a shape in which a plurality of rectangular support members (520E-3) are arranged to include each other, as shown in FIG. 17, when the foldable mask inhaler (10E) is folded. And when the user unfolds the foldable mask inhaler (10E), it may have a shape in which a plurality of cylindrical support members (520E-3) are stacked, as shown in FIG. 16.

As an example, as shown in FIG. 18, a plurality of protruding members (570E-1) may be formed on the inner surface of a plurality of support members (520E-3). In an example, a plurality of protruding members (570E-3) may be arranged more on the support members (520E-3) arranged on the outer side.

Fig. 19 shows another embodiment of a foldable mask inhaler (10F), and Figs. 20 and 21 show a lead (500F) according to Fig. 19.

The foldable mask inhaler (10F) according to the present embodiment may have a different configuration of the lead (500F) compared to the foldable mask inhaler (10) according to the above-described embodiment. The remaining configuration of the foldable mask inhaler (10F) may be the same as that of the foldable mask inhaler (10), and a detailed description thereof will be omitted.

In one embodiment, the foldable mask inhaler (10F) may include a frame (100F), a cover (200F), a ring (300F), and a lid (500F), and a drug (D) and a packaging container (not shown). Additionally, the foldable mask inhaler (10F) may not include a porous layer assembly.

The frame (100F), the cover (200F), the ring (300F) and the drug (D) may be the same as the frame (100), the cover (200), the ring (300) and the drug (D), and a detailed description thereof is omitted.

As shown in Fig. 19, the lead (500F) can be placed on the side of the frame (100F) facing the user's face. The lead (500F) can be a cigarette-shaped one in which a thin film of paper or a similar material is rolled up. In addition, the lead (500F) can have a drug (D) applied to at least one surface thereof, as shown in Figs. 20 and 21. That is, unlike the above-described embodiment, the foldable mask inhaler (10F) does not include a separate protective member (600F), and the drug (D) can be applied to the lead (500F) itself. In this state, the lead (500F) can be rolled up into a cigarette-shaped one and placed on one side of the frame (100F). Then, when the user puts his/her mouth on the lead (500F) and inhales, the drug (D) applied to the surface of the lead (500F) can flow and move to the mouth.

As an example, the lead (500F) may have a cylindrical shape, similar to the leads (500E-1, 500E-2, 500-3) described above, or a shape having a wider gap in one direction, or a shape in which cylindrical supports are formed concentrically and are stacked in the height direction. In addition, the lead (500F) may also include a plurality of protruding members, similar to the leads (500E-1, 500E-2, 500-3) described above, and the protruding members may be packed more densely as they go outward in the radial direction.

Although the present invention has been described with reference to the embodiments illustrated in the drawings, these are merely examples. Those skilled in the art will readily understand that various modifications and equivalent other embodiments are possible from the embodiments. Therefore, the true technical protection scope of the present invention should be determined based on the appended claims.

The present invention can be used in the industry related to foldable mask inhalers.
