Description

Quasi-nano device

Technical Field

The invention 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. The function of the sliding rod of the quasi-sodium device is as follows: the sliding rod at the initial position mainly plays a role in protecting and shielding the hollow bladder and reducing pollution; when the slide bar is fully toggled to the end position, the action of this process: the shielded empty bubble bag is rotated away from the suction nozzle cavity, and a new bubble filled with medicine powder is moved to a position opposite to the suction nozzle cavity, so that preparation is made for inhalation.

For example, in US5590645, the actuation step (opening and preparation) of the device is relatively complex, and the patient is liable to operate by mistake during the use of the device, if the user does not dial the slide rod to start inhalation, at this time, ineffective administration is caused because the mouthpiece is blocked by the slide rod and the blister in the administration position is the empty blister after the last use; if the user does not toggle the sliding rod to a preset position, the blister cannot face the suction nozzle or the condition that the sliding rod partially shields the blister occurs, so that part of dry powder can remain in the blister during inhalation, and the accuracy of the administration dosage is affected; 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.

The susceptors of the present invention are described in detail below with reference to fig. 1 to 8.

In the present embodiment, as shown in fig. 1 and 8, the susceptors 100 include a housing 1, a barrier cap 2, a medicine dispensing assembly (not shown in the drawings), a trigger 3, and a link mechanism 4, and the housing 1 includes a cavity, a suction nozzle 11, and a relief through hole 12. The protective cover 2 is rotatably connected to the outside of the housing 1, the drug dispensing assembly is located in the cavity, the trigger member 3 is rotatably connected to the inside of the housing 1, and the trigger member 3 is used for triggering the drug dispensing assembly to dispense the drug. It will be appreciated that the medicament dispensing assembly may be of the type employing the medicament dispensing structure of a conventional susceptors, and typically the medicament dispensing assembly of the susceptors comprises a main wheel, a blister roll rotatably connected within the housing 1 and provided with a plurality of medicament blisters, a blister substrate roll for collecting blister torn substrates, and a blister cover roll for collecting blister torn covers, the trigger member 3 being rotated by triggering the main wheel to trigger the medicament dispensing assembly to dispense medicament, wherein the assembly structure of the main wheel, blister roll, blister substrate roll and blister cover roll is referred to the structure of the conventional susceptors.

As shown in fig. 1, one end of the link mechanism 4 is rotatably connected to the trigger member 3 from the position of the yielding through hole 12, and the other end is rotatably connected to the protective cover 2, so that the link mechanism 4, the trigger member 3 and the protective cover 2 form a linkage mechanism.

As shown in fig. 1 and 7, when the susceptors 100 are in the initial state, the protective cover 2 is in the initial position, the protective cover 2 closes the mouthpiece 11, protects the mouthpiece 11 from contamination of the vesicles in the mouthpiece 11 and in the housing 1, and the triggering member 3 is in the initial position.

When the protective cover 2 is opened by an external force, the protective cover 2 rotates, the protective cover 2 pulls the link mechanism 4, so that the link mechanism 4 rotates around the connection part of the link mechanism and the trigger piece 3 to a direction far away from the suction nozzle 11, the protective cover 2 continues to rotate, the link mechanism 4 starts to pull the trigger piece 3 to rotate together, and when the protective cover 2 moves to the fully opened position, the rotation is stopped, and at this time, the trigger piece 3 rotates to the trigger position, as shown in fig. 8. During rotation of the trigger member 3, the main wheel rotates to trigger the blister roll, blister substrate roll and blister cover roll to rotate respectively to begin dispensing of medicament, when the trigger member 3 rotates to the trigger position, empty blisters are removed, new blisters on the blister roll are aligned with the mouthpiece 11 and the mouthpiece 11 is fully exposed, and a tear mechanism (not shown) tears the cover of a new blister aligned with the mouthpiece 11, whereupon the register 100 is ready for administration and the user holds the mouthpiece 11 for inhalation of medicament.

When the external force drives the protective cover 2 to reset, the link mechanism 4 pulls the trigger piece 3 to rotate, and then drives the trigger piece 3 to reset.

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.
