Description

Quasi-nano device

Technical Field

The utility model relates to the technical field of powder inhalation devices, in particular to a quasi-nano device.

Background

The oral inhalation administration mode is an administration mode requiring the coordination of a medicine instrument, and is an important administration way for treating various diseases including lung and whole body. The inhalation powder mist Advair Diskus Preparer (Fluticasone propionate salmeterol Luo Xiru powder) from GlaxoSmithKline is one of the most commonly used inhalants for the treatment of asthma and chronic obstructive pulmonary disease.

The steps of using the quasi-nano device are generally as follows:

1) Opening the outer cover: holding the cover with one hand and putting the thumb of the other hand on the thumb handle to push the thumb outwards until the cover is completely opened;

2) Preparing for drug inhalation: holding the register to enable the suction nozzle to face the register, pushing the sliding rod outwards until clicking sound is generated, and triggering the opening of the blister;

3) Inhalation: holding the quasi-container and keeping the quasi-container away from the mouth, exhaling as much as possible on the premise of ensuring stable breathing, putting the suction nozzle into the mouth, deeply and stably sucking the medicine by the quasi-container, and taking the quasi-container out of the mouth; continuing to hold breath for about 10 seconds; slowly resume exhalation;

4) Closing means: the thumb is placed on the thumb handle and pulled backwards as soon as possible, and when the register is closed, a click sound is generated to indicate closing;

5) Rinsing the mouth: after the inhalation is completed, the mouthwash is not swallowed.

It is critical for the patient to be able to ensure a correct administration step on the basis of the ease of use of the inhalation device. Before inhalation, two steps of opening the quasi-nano device and preparing for inhalation are needed, and only the two steps are correctly completed, the subsequent inhalation of the medicine powder can be ensured. The main function of the cover sleeve of the quasi-container is to protect the suction nozzle and the sliding rod of the device, so that the suction nozzle can be prevented from being polluted due to exposure to the environment, and the sliding rod can be prevented from sliding in a non-drug administration state. When the slide bar is fully moved to the end position, the empty bubble bag is far away from the suction nozzle, and simultaneously, a new bubble filled with medicine powder is moved to a position opposite to the cavity of the suction nozzle, so that preparation is made for suction.

For example, in US5590645, the starting step (opening and preparation) of the device is relatively complex, the operation is complicated, and the patient is liable to operate by mistake during the use of the device, and if the user does not toggle the slide rod to start inhalation, at this time, the blister in the administration position is empty after the last use, resulting in ineffective administration; if the user erroneously operates the slide bar for a plurality of times, the opened blister pocket in the device moves along with the strip of medicine, and medicine powder is still stored in the blister pocket, so that the medicine powder is polluted and wasted.

In summary, since the quasi-nano device has a relatively complex structure, the device is easy to operate erroneously in the process of opening and preparing, and the subsequent inhalation process of the quasi-nano device is directly affected, so that the drug administration is failed or is not completely performed, and the drug administration efficiency is reduced.

In this embodiment, as shown in fig. 1, 2, 6, 9 and 11, the nano-device 100 includes a housing 1, a protective cover 2, a main wheel 3 and a medicine dispensing component (not shown in the drawings), the housing 1 is provided with a cavity, a first yielding through hole 11 and a suction nozzle 12, the protective cover 2 is located outside the housing 1 and is rotatably connected to the housing 1, when the nano-device 100 is in an initial state, the protective cover 2 covers an outlet end of the suction nozzle 12, the protective cover 2 protects the suction nozzle 12, the suction nozzle 12 and a blister in the housing 1 are prevented from being polluted, the main wheel 3 is located in the cavity of the housing 1 and is rotatably connected to the housing 1, and the medicine dispensing component is located in the cavity and is rotatably connected to the housing 1.

As shown in fig. 1 and 2, the inner wall of the protective cover 2 is provided with an actuating member 21, the main wheel 3 includes a first gear portion 31 and an eccentrically disposed protruding portion 32, the protruding portion 32 protrudes out of the first relief through hole 11, and the first gear portion 31 cooperates with the medicament dispensing assembly. It will be appreciated that the medicament dispensing assembly may be of the type employing the medicament dispensing structure of a conventional register, and that the medicament dispensing assembly of the register generally comprises a blister roll rotatably connected within the housing 1 and provided with a plurality of medicament blisters, a blister substrate roll for collecting the blister-torn substrate, and a blister cover roll for collecting the blister-torn cover, the first gear portion 31 being in mating relationship with the medicament dispensing assembly in reference to the mounting structure of the conventional register.

As shown in fig. 1, when the register 100 is in the initial state, the protrusion 32 is located at the initial position, and if the register 100 is used last time, the position of the blister pocket on the blister roll is opposite to the position of the suction nozzle. When the protective cover 2 is rotated in a first direction to expose the mouthpiece 12 by an external force as shown in fig. 1 and 2, the actuating member 21 of the protective cover 2 rotates to abut against the boss 32, at this time, the protective cover 2 continues to rotate, and the actuating member 21 applies an urging force to the boss 32 in the first direction to push the main wheel 3 to rotate synchronously, and in addition, because the first gear 31 is matched with the medicine dispensing component, the main wheel 3 rotates to trigger the blister roll, the blister base material roll wheel and the blister cover sheet roll wheel to rotate respectively, so as to start medicine dispensing, when the main wheel 3 rotates to the trigger position, the empty blister is removed, a new blister on the blister roll is opposite to the position of the mouthpiece 12, and the mouthpiece 12 is completely exposed, and the tearing mechanism (not shown in the figure) tears the cover sheet of the new blister opposite to the position of the mouthpiece 12, at this time, as shown in fig. 9, the register 100 is in a state ready for medicine administration, and the user holds the blister 12.

It should be appreciated that, in order to avoid that the protective cover 2 is easily rotated to erroneously trigger dispensing, the protective cover 2 is arranged to be rotated under a certain external force, for example, by increasing the assembly friction between the protective cover 2 and the housing 1, so as to avoid that the protective cover 2 is easily rotated. Of course, since the protective cover of the existing level shifter cannot be easily rotated, the structure for limiting the easy rotation of the protective cover 2 is not limited thereto, and may be any limiting structure of the configuration of the existing level shifter, which is not described herein.

It should be understood that the user manually opens and closes the barrier cover 2 for convenience of operation.

Through adopting above-mentioned technical scheme, when using accurate ware 100 that receives, main wheel 3 takes place to rotate when opening protective cover 2, and an action just can accomplish and open protective cover and prepare two operation steps of inhaling, the simple operation. Moreover, for the technical scheme that triggers the dispensing through opening the enclosing cover and stirring two operation steps of slide bar in traditional scheme, in this scheme, on the one hand, because if not open protective cover 2, suction nozzle 12 is covered and is led to unable holding, therefore the user generally can not forget to open protective cover 2, and then can avoid taking place the condition of invalid dosing, on the other hand, because the user generally can not relapse the switching protective cover again and again, so can avoid leading to the new vesicle to be opened and the condition of unutilized because of the false triggering is dosed, avoid the medicine extravagant, and then can improve the efficiency of dosing.

In an embodiment, as shown in fig. 2, the inner wall of the protective cover 2 is provided with a limiting member 22, and when the register 100 is in an initial state, the limiting member 22 limits the boss 32 to an initial position, so as to limit the main wheel 3 from rotating under shaking conditions, and the medicament is dispensed by error triggering.

Of course, since the main wheel 3 is matched with the drug dispensing assembly, the main wheel 3 needs to overcome the resistance of the drug dispensing assembly to rotate, so that the main wheel 3 cannot easily rotate, and the stopper 22 may not be provided to limit the main wheel 3 to easily rotate in the register 100. Preferably, the stopper 22 is provided to ensure stability of the susceptors 100.

Further, as shown in fig. 2, the limiting member 22 is a bump, which has a simple structure and is convenient for processing. When the register 100 is in the initial state, the limiting member 22 presses the protruding portion 32 against the first end 111 of the first yielding through hole 11, and the protruding portion 32 is clamped by the limiting member 22 and the first end 111, so as to achieve a stable limiting effect. Specifically, when dispensing medicine, the protective cover 2 rotates in the first direction under the external force to expose the suction nozzle 12, the actuating member 21 and the limiting member 22 move synchronously, at this time, the limiting member 22 moves away from the boss 32 and the actuating member 21 moves towards the boss 32, and after the actuating member 21 moves to abut against the boss 32, the actuating member 21 drives the boss 32 to rotate, at this time, the main wheel 3 starts to rotate until the main wheel 3 moves to the triggering position, and medicine can be inhaled. When the protective cover 2 rotates in a second direction opposite to the first direction under an external force to reset, the actuating member 21 and the limiting member 22 synchronously rotate in opposite directions, at this time, the actuating member 21 moves away from the protruding portion 32 and the limiting member 22 moves towards the protruding portion 32, and when the limiting member 22 moves to abut against the protruding portion 32, the limiting member 22 can push the protruding portion 32 to rotate in opposite directions so as to drive the main wheel 3 to reset. In this embodiment, the stopper 22 has both the function of stopping and resetting the initial position of the boss 32.

It should be appreciated that the cross-sectional shape of the projection of the stop 22 includes, but is not limited to, square, circular, triangular, polygonal.

Of course, the structure of the limiting member 22 is not limited thereto, but also includes, but is not limited to, a spring or a magnetic attraction structure, if the limiting member 22 is positioned in the spring, one end of the spring is connected to the boss 32, and the other end is connected to the housing 1, and when the register 100 is in the initial state, the spring tightens the boss 32 so that it is in the initial position; when the protruding part 32 is in the triggering position, the spring is stretched, and after the external force applied to the protective cover 2 is removed, the spring rebounds to enable the main wheel 3 to reset together with the protective cover 2, and the spring also has the functions of limiting and resetting the initial position of the protruding part 32 in the scheme. If the limiting member 22 is in a magnetic structure, the protruding portion 32 is made of iron, and the protruding portion 32 is adsorbed by the limiting member 22 to play a limiting role.

Further, as shown in fig. 2, the actuating member 21 is a bump, and the actuating member 21 and the limiting member 22 are located on the circumference of the movement track of the protruding portion 32; when the register 100 is in a state of preparing for administration, the actuator 21 presses the protruding portion 32 against the second end 112 of the first yielding through hole 11, and the protruding portion 32 is clamped together by the actuator 21 and the second end 112, so that the main wheel 3 is stably located at the triggering position, and thus, the actuator 21 has the functions of actuating and limiting the triggering position of the protruding portion 32, and the structure is simple and convenient to process.

It should be appreciated that the cross-sectional shape of the tab of the actuator 21 includes, but is not limited to, square, circular, triangular, polygonal.

Of course, the structure of the actuator 21 is not limited thereto, and may be a magnetic attraction structure, and the protrusion 32 is driven to rotate synchronously by magnetic attraction.

In an embodiment, as shown in fig. 1 and 8, the first yielding hole 11 extends along the movement track of the protruding portion 32, so that the first yielding hole 11 is in a shape of a curved waist-shaped hole, so as to reduce the size of the first yielding hole 11, and prevent external dust and/or bacteria from entering the housing 1 through the first yielding hole 11, thereby avoiding pollution of the bladder. Of course, the first relief hole 11 may be square or circular, so that the first relief hole 11 has a larger free space, and the bladder is easily contaminated.

Further, as shown in fig. 1, the housing 1 is provided with an annular groove 16, and when the barrier cover 2 is rotated, the actuator 21 and the stopper 22 are rotated along the annular groove 16. The actuating element 21 and the limiting element 22 each extend partially into the annular recess 16, which facilitates a smaller design of the register 100, since the inner wall of the protective cover 2 is closer to the outer wall of the housing 1.

In an embodiment, as shown in fig. 5 to 7, the register 100 further includes a triggering auxiliary member 4, the triggering auxiliary member 4 is rotatably connected to the inside of the housing 1, the triggering auxiliary member 4 includes a second gear portion 41 and a baffle plate 42, the second gear portion 41 is meshed with the first gear portion 31, and when the register 100 is in an initial state, the baffle plate 42 covers an inlet end of the suction nozzle 12, so as to protect and shelter from a blister in the housing 1 from being polluted. When the main wheel 3 is rotated to trigger the preparation of a dose, the trigger aid 4 is rotated in the opposite direction due to the meshing relationship of the first gear portion 31 and the second gear portion 41, and the shutter 42 is moved away from the mouthpiece 12 to expose the inlet end of the mouthpiece 12 to cooperate with the subsequent dose administration.

Further, as shown in fig. 5, 8 and 9, the circumferential outer wall of the housing 1 is provided with a second relief through hole 13; the trigger aid 4 includes a position indicating portion 43, the position indicating portion 43 being positioned opposite the second relief through hole 13 to indicate a change in the circumferential position of the trigger aid 4. Specifically, the shield cap 2 is rotated but not rotated to the trigger position, and the blister cannot be aligned with the mouthpiece 12 or the shield plate 42 partially shields the blister, resulting in a portion of the dry powder remaining in the blister during inhalation, which can affect the accuracy of the dose. In this embodiment, the position indication part 43 is provided to indicate whether the user admittance 100 is in the accurate administration state, so as to avoid insufficient administration dosage.

Further, as shown in fig. 9, the position indication portion 43 passes through the second relief through hole 13 to be partially located outside the housing 1, indicating more clearly.

Further, as shown in fig. 5 and 9, the position indicating portion 43 includes a first rod 431 and a second rod 432 connected to each other, the second rod 432 is inserted into the second relief hole 13, and the first rod 431 is located outside the housing 1. The first rod 431 and the second rod 432 intersect, and the position indication can be performed more intuitively. Further, the first lever 431 is provided close to the outer wall of the housing 1 to reduce the probability of the user erroneously touching the position indication portion 43, thereby avoiding the actuation of the dispensing.

In one embodiment, as shown in fig. 1, the housing 1 includes a first limit structure 14 and a second limit structure 15 for limiting an initial position and a drug delivery position of the protective cover 2, respectively, specifically, as shown in fig. 11, when one side of the housing 1 is limited to the first limit structure 14, the susceptors 100 are in an initial state; as shown in fig. 9, when the other side of the housing 1 is limited to the second limiting structure 15, the susceptors 100 are in a ready-to-administer state, which is advantageous for a user to conveniently and accurately use the susceptors.

In one embodiment, as shown in fig. 10, the housing 1 includes a first shell 17 and a second shell 18, and the two are connected to form a cavity to facilitate the accommodation of the internal components of the register 100.

Further, as shown in fig. 6 and 7, the main wheel 3 is rotatably coupled to the inner wall of the first housing 17 through a first rotation shaft 191.

Further, as shown in fig. 6 and 7, the trigger assistant member 4 is rotatably connected to the inner wall of the first housing 17 through the second rotation shaft 192.

It should be understood that the "initial position" and the "trigger position" above match the corresponding parts, and that the protective cover 2, the main wheel 3 and the trigger aid 4 have different initial and trigger positions, respectively.

It should be understood that the above examples are illustrative and are not intended to encompass all possible implementations encompassed by the claims. Various modifications and changes may be made in the above embodiments without departing from the scope of the disclosure. Likewise, the individual features of the above embodiments can also be combined arbitrarily to form further embodiments of the utility model which may not be explicitly described. Therefore, the above examples merely represent several embodiments of the present utility model and do not limit the scope of protection of the patent of the present utility model.
