FIELD OF THE DISCLOSURE

The present disclosure relates to a medication adjustment device and a nebulizer, and more particularly to a medication adjustment device and nebulizer capable of controlling the amount of medicinal liquid.

BACKGROUND OF THE DISCLOSURE

Nebulizers for medical use mainly deliver drugs through the respiratory system. The nebulizers nebulize the medicinal liquid into small particles with a specific particle size and deliver the small particles from the user's mouth and nose into the respiratory system of the user's body through breathing for treatment purposes.

A reservoir inside the existing nebulizer contains a fixed amount of medicinal liquid, and the nebulizer cannot control the specific amount of medicinal liquid to be nebulized in the reservoir. Furthermore, while packaging medicinal liquid, a fixed amount of the medicinal liquid is contained in a medicine package. When a user pours the medicinal liquid in the medicine package into the nebulizer, the amount of medicinal liquid in the medicine package is not necessarily equal to the amount of the medicinal liquid required by the user. For example, if the amount of the medicine package in the medicine package is 10 ml, the amount of the medicinal liquid required by the user may only be 5 ml. Therefore, it is difficult for the user to adjust the amount of the medicinal liquid poured into the nebulizer by himself.

On the other hand, during treatment with a nebulizer, the activated nebulizer continues to nebulize until the medicinal liquid in the reservoir is exhausted. If the amount of medicinal liquid required for treatment is lower than the amount of liquid in the medicine package, it is difficult for the user to evaluate when to manually turn off the nebulizer, which can result in an excessive amount of the medicinal liquid being inhaled, thereby affecting the therapeutic effect.

SUMMARY OF THE DISCLOSURE

In response to the above-referenced technical inadequacies, the present disclosure provides a medication adjustment device and a nebulizer.

In order to solve the above-mentioned problems, one of the technical aspects adopted by the present disclosure is to provide a medication adjustment device, which includes a liquid reservoir and a medication adjustment member. The liquid reservoir includes a first opening and a second opening. The liquid reservoir includes an accommodating cavity, and the first opening communicates with the second opening through the accommodating cavity. The medication adjustment member is detachably disposed on the first opening and located in the accommodating cavity. The medication adjustment member includes a third opening and an adjustment opening. The medication adjustment member includes an adjustment chamber therein. The third opening communicates with the adjustment opening, and the adjustment opening communicates with the second opening.

In order to solve the above-mentioned problems, another one of the technical aspects adopted by the present disclosure is to provide a nebulizer, which includes a medication adjustment device and a nebulizing module. The medication adjustment device includes a liquid reservoir and a medication adjustment member. The liquid reservoir includes a first opening and a second opening.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

First Embodiment

Reference is made toFIG.1andFIG.2. A first embodiment of the present disclosure provides a medication adjustment device B that can be applied to a nebulizer. The medication adjustment device B includes a liquid reservoir1, a medication adjustment member2, and a cover3. The liquid reservoir1includes a first opening11and a second opening12. The medication adjustment member2is detachably disposed inside the liquid reservoir1. The cover3is disposed on the liquid reservoir1and covers the first opening11of the liquid reservoir1.

Reference is made toFIG.2toFIG.4. The liquid reservoir1includes an accommodating cavity C1therein, and the first opening11communicates with the second opening12through the accommodating cavity C1. The medication adjustment member2is disposed in the accommodating cavity C1. The medication adjustment member2includes a third opening21and an adjustment opening22. The third opening21communicates with the adjustment opening22, and the adjustment opening22communicates with the second opening12of the liquid reservoir1. When the medication adjustment member2is disposed inside the reservoir1, the third opening21of the medication adjustment member2overlaps with the first opening11of the reservoir1. Therefore, the cover3is disposed on the liquid reservoir1to cover the first opening11as well as the third opening21. In addition, the medication adjustment member2includes an adjustment chamber C2therein.

Reference is made toFIG.4. In the first embodiment, the adjustment opening22is a cylindrical opening that includes a first port221and a second port222. The first port221penetrates a bottom of the medication adjustment member2, and the second port222extends toward the third opening21, such that the adjustment opening22has a height from the bottom of the medication adjustment member2. Moreover, a direction in which the adjustment opening22extends is perpendicular to a direction in which the second opening12extends. The adjustment chamber C2is formed between a first peripheral wall R1of the adjustment opening22and a second peripheral wall R2of the medication adjustment member2.

Reference is made toFIG.2andFIG.3. The medication adjustment member2further includes a first annular portion23and a second annular portion24. The first annular portion23is disposed around an outer periphery of the third opening21. The second annular portion24is located below the first annular portion23and extends outward along a radial direction of the adjustment opening22to partially cover an area of the accommodating cavity C1. The second annular portion24is disposed around an outer periphery of the adjustment opening22. The first annular portion23includes a first limiting protrusion portion231. The second annular portion24includes a second limiting protrusion portion241. An inner wall of the liquid reservoir1includes a limiting groove13. Contour shapes of the first limiting protrusion portion231and the second limiting protrusion portion241correspond to a contour shape of the limiting groove13. When the medication adjustment member2is disposed in the accommodating cavity C1, the first limiting protrusion portion231and the second limiting protrusion portion241are engaged (e.g., snapped) into the limiting groove13, such that the medicine adjustment member2is disposed inside the liquid reservoir1in a fixed orientation.

Reference is made toFIG.2,FIG.4, andFIG.5. The medication adjustment device B further includes a sealing member4. The sealing member4is surroundingly disposed outside the second annular portion24. When the medicine adjustment member2is disposed in the accommodating cavity C1, the sealing member4is engaged (e.g., snapped) between the second annular portion24and the inner wall of the liquid reservoir1. The sealing member4can be, for example, an elastic sealing ring (i.e., an O-ring). Alternatively, in other embodiments, the sealing member4can be a rib that is integrally formed with the second annular portion24.

Reference is made toFIG.5. The cover3includes an annular partition wall31. When the cover3is disposed on the liquid reservoir1, the annular partition wall31abuts against the first peripheral wall R1of the adjustment opening22to close the second port222. Since a volume of the adjustment chamber C2of the medicine adjustment member2can be determined at the beginning of the design, designers can estimate the redundant amount of the medicinal liquid in the medicine package based on the amount of the medicinal liquid in the medicine package and the required amount of the medicinal liquid for the user, and accordingly design the volume in the adjustment chamber C2to be equal to the volume of the redundant medicinal liquid.

As shown inFIG.5, the amount of the medicinal liquid M1in the accommodating cavity C1and the adjustment opening22is the amount of medicinal liquid expected to be used (i.e., the required amount of medicinal liquid for the user). The amount of the medicinal liquid M2in the adjustment chamber C2is the residual amount of medicinal liquid (i.e., the redundant amount of the medicinal liquid). When the user pours the medicinal liquid in the medicine package into the liquid reservoir1with the medicine adjustment member2inside, the medicinal liquid enters through the third opening21and flows into the accommodating cavity C1through the adjustment opening22, and fills a space in the accommodating cavity C1and the adjustment opening22. Furthermore, when the amount of medicinal liquid is excessive, the redundant amount of the medicinal liquid overflows from the adjustment opening22and flows into the adjustment chamber C2. After that, the cover3covers the third opening21, and the annular partition wall31abuts against the first peripheral wall R1of the adjustment opening22to block the adjustment opening22from the adjustment chamber C2, which prevents the redundant amount of medicinal liquid in the adjustment chamber C2from penetrating the accommodating cavity C1while the nebulizer is shaken or tilted, and prevents the expected medicinal liquid in the accommodating cavity C1from penetrating the adjustment chamber C2. In addition, through the arrangement of the sealing member4, the medicinal liquid in the accommodating cavity C1can be further prevented from leaking from a boundary of the second annular portion24.

Reference is made toFIG.5andFIG.9. The present disclosure also provides a nebulizer E, which includes the medication adjustment device B, and a nozzle assembly B1, a main body B2, and a nebulizing module B3that are disposed on the medication adjustment device B. Specifically, the nozzle assembly B1is disposed on the second opening12of the liquid reservoir1, and the liquid reservoir1is disposed on the main body B2. The nebulizing module B3is disposed inside the liquid reservoir1and is located at a connection position between the second opening12and the accommodating cavity C1. Therefore, the medicinal liquid expected to be used in the accommodating cavity C1can be nebulized through the nebulizing module B3to generate aerosol, and then enter the respiratory system of the user's body through the user's mouth and nose to achieve treatment purposes.

Second Embodiment

Referring toFIG.6toFIG.8, a second embodiment of the present disclosure provides a medication adjustment device B′ that can be applied to a nebulizer E. The medication adjustment device B′ of the second embodiment is similar to the structure of the first embodiment, and the similarities (e.g., the liquid reservoir1and the cover3) will not be reiterated herein. The main difference between the second embodiment and the first embodiment is the structure of the medication adjustment member2.

Specifically, in the second embodiment, the medication adjustment member2includes a third opening21and an adjustment opening22, and the medication adjustment further includes an adjustment chamber C2therein. The third opening21communicates with the adjustment opening22, and the adjustment opening22communicates with the second opening12. As shown inFIGS.6and7, the medication adjustment member2is a funnel-shaped structure, which includes a side wall25and a bottom wall26. The side wall25has a first side251and a second side252that are opposite to each other. The adjustment opening22is formed on the first side251, and the adjustment opening22is positioned directly opposite to the second opening12; that is, a direction in which the adjustment opening22extends is parallel to a direction in which the second opening12extends. The bottom wall26slopes downward from the first side251to the second side252, and the bottom wall26and the side wall25jointly forms the adjustment chamber C2.

As shown inFIG.6, the medication adjustment member2includes a supporting portion27. The supporting portion27is disposed around an outer periphery of the third opening21. The medication adjustment member2is detachably disposed in the first opening11and located in the accommodating cavity C1. Furthermore, the supporting portion27is engaged (e.g., snapped) on the edge of the first opening11and seals the first opening11. The supporting portion27includes a limiting protrusion portion271. The limiting protrusion portion271is located directly opposite to the adjustment opening22. An inner wall of the liquid reservoir1includes a limiting groove13(inFIG.3), and a contour shape of the limiting protrusion portion271corresponds to a contour shape of the limiting groove13. When the medication adjustment member2is disposed in the accommodating cavity C1of the liquid reservoir1, the limiting protrusion portion271is disposed in the limiting groove13, such that the medicine adjustment member2is disposed inside the liquid reservoir1in a fixed orientation.

As shown inFIG.8, when the cover3is disposed on the liquid reservoir1, the annular partition wall31of the cover3abuts against the bottom of the liquid reservoir1. Specifically, the annular partition wall31abuts against an upper edge of the side wall25of the liquid reservoir1to block the adjustment opening22from the adjustment chamber C2. When the user pours the medical liquid in the medicine package into the liquid reservoir1with the medicine adjustment member2inside, the medicinal liquid (not shown inFIG.8) enters through the third opening21and flows into the accommodating cavity C1through the adjustment opening22, and fills a space in the accommodating cavity C1. An amount of the medicinal liquid that exceeds the amount to be adjusted by the medicine adjustment member2overflows from the regulating opening22and flows back to the adjustment chamber C2. After that, the cover3covers the third opening21, and the annular partition wall31abuts against the side wall25to block the adjustment opening22from the adjustment chamber C2, which prevents the redundant amount of medicinal liquid in the adjustment chamber C2from penetrating the accommodating cavity C1while the nebulizer is shaken or tilted, and prevents the expected medicinal liquid in the accommodating cavity C1from penetrating the adjustment chamber C2.

Beneficial Effects of the Embodiments

In the medication adjustment device B, B′ and the nebulizer E provided by the present disclosure, the medication adjustment member2is disposed inside the liquid reservoir1of the nebulizer E, and the adjustment chamber C2in the medication adjustment member2is used to accommodate a redundant amount of the medicinal liquid in the medicine package, so as to ensure that the amount of the medicinal liquid flowing into the liquid reservoir1is exactly the amount of the medicinal liquid required by the user. Moreover, in the medication adjustment device B, B′ provided by the present disclosure, the annular partition wall31blocks the adjustment opening22from the adjustment chamber C2to prevent the redundant amount of medicinal liquid in the adjustment chamber C2from penetrating the accommodating cavity C1while the nebulizer is shaken or tilted, and prevents the expected medicinal liquid in the accommodating cavity C1from penetrating the adjustment chamber C2.

Furthermore, since the medication adjustment member2and the liquid reservoir1are detachable components, the medication adjustment member2(e.g., the medication adjustment member2inFIG.5orFIG.8) in the medication adjustment device B, B′ can be appropriately selected base on different users, such as adults and children, to accurately control the amount of the medicinal liquid and avoid overdose. In addition, the user can change the required amount of the medicinal liquid by replacing the medicine adjusting member2with one of a different volume. Therefore, the structure of the nebulizer E does not need to be significantly modified due to different amounts of the medicinal liquid to meet the needs of various medicine packages of different sizes.
