Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of atomization, and particularly relates to a disposable atomization inhalation generating device. BACKGROUND

[0002] The existing atomizer includes an atomizer main machine and a mask connected to the atomizer main machine through a pipeline or other channels. The atomizer main machine is shown in the Chinese patent with the publication number CN207722192U. The patent discloses a circuit assembly, a drug liquid storage assembly, a drug liquid atomization assembly, an out-mist transmission channel, and a user connection end. The circuit assembly drives the drug liquid atomization assembly to atomize the drug liquid stored in the drug liquid storage assembly, and connects the mist-shaped drug liquid (aerosol) generated in the drug liquid atomization assembly to the user through the out-mist transmission channel. However, the existing atomizer is mostly reusable, and there is a risk of cross-infection. In addition, the existing atomizer is not only used for atomization treatment, but also can be used for inhalation vaccination of vaccines. For vaccination, the dose per person is 0.1 mL. If inhalation fails, it needs to be vaccinated again. According to the judgment of medical staff on the spot, if the following situations occur, it is considered that inhalation has failed. 1. There is obvious mist gas in the atomization cup after inhalation, that is, the actual inhalation amount is low, and the vaccination dose cannot be reached; 2. Coughing, premature exhalation, etc. occurs during the inhalation process (including the 5-second holding breath period). For the above-mentioned second situation, medical staff can easily judge. However, for the above-mentioned first situation, the judgment of medical staff on the residual amount of mist gas in the atomization cup is subjective, and different medical staff may give different results. In addition, the inner wall of the atomization cup is easy to condense water droplets, which also affects the judgment of medical staff on the residual amount of mist gas in the cup. Therefore, how to more simply judge the atomization inhalation amount of patients or vaccinated persons is a problem to be solved at present. SUMMARY

[0003] The present application aims to overcome the problem that the existing atomization device is not conducive to judging the actual atomization inhalation amount of patients or vaccinated persons, and provides a disposable atomization inhalation generating device, which comprises:

[0004] A shell, the inside of which is a hollow cavity, and a partition plate is arranged inside the shell for separating the hollow cavity into a first cavity and a second cavity; a first communication groove is arranged on the partition plate to communicate the first cavity and the second cavity, and the shell is further provided with a transparent observation window for observing the second cavity;

[0005] An atomization device is arranged in the first cavity of the shell, which is used to atomize the medicament injected into the first cavity to generate aerosol;

[0006] a quantitative container disposed in the second cavity of the housing, the quantitative container having a soft, deformable structure located within the viewing window of the transparent observation window; the quantitative container is also in communication with the first cavity and is used to collect aerosols in the first cavity; and

[0007] The user connection end is arranged outside the shell and is communicated with the quantitative container.

[0008] Furthermore, the quantitative container includes a connected hard bottom box and a soft pouch, and the pouch is the soft deformable structure; the bottom box is provided with a second communicating groove and an atomization outlet, the second communicating groove is connected to the first communicating groove, and the atomization outlet is connected to the user connection end.

[0009] The hard bottom box and the soft pouch are connected, and the bottom box is used to maintain effective communication between the quantitative container, the first communicating groove, and the user connecting end, which is more conducive to the aerosol generated by the atomizing device entering the bottom box and the pouch.

[0010] Furthermore, there are multiple pouches, which are connected in series and communicated in sequence.

[0011] The amount of aerosol inhaled is determined by the deformation of the pouch, and storing aerosols in pouches connected in series not only realizes the partitioned storage of aerosols, but also facilitates the deformation of a single pouch. The remaining amount of aerosol in the quantitative container can also be determined by the number of deformed pouches, making the judgment more intuitive and clear.

[0012] Furthermore, the generating device also includes a medicine bottle and a puncture device; the shell is provided with a medicine injection port and a sealing cover for opening or closing the medicine injection port on the surface corresponding to the first cavity; the medicine bottle stores medicine; the puncture device is arranged in the first cavity, for puncturing the medicine bottle entering the first cavity from the medicine injection port, so that the medicine in the medicine bottle is injected into the first cavity.

[0013] Furthermore, the puncture device comprises:

[0014] A soft plastic sheet having a through hole in its center, and an outer edge of the soft plastic sheet is fixed to the inner wall of the first cavity;

[0015] A fixed bracket is arranged below the soft plastic sheet and fixedly connected to the inner wall of the first cavity, and a guide channel is provided on the fixed bracket;

[0016] The lower end of the puncture needle is connected to the fixed bracket, and the upper end of the puncture needle is a sharp thorn portion. The sharp thorn portion is inserted into the through hole of the soft plastic sheet and contacts and cooperates with the through hole, and extends above the soft plastic sheet.

[0017] The spike portion contacts and cooperates with the through hole of the soft film to close the drug injection chamber when no medicine bottle is inserted, wherein the drug injection chamber is located in the upper area of ​​the soft film in the first cavity.

[0018] Furthermore, the puncture device also includes a guide plate fixed on the puncture needle, and the guide plate is provided with a guide hole; the guide plate is coaxially nested in the through hole of the soft plastic film and abuts against the hole wall of the through hole.

[0019] Through the deflector disc attached to the puncture needle, once the puncture needle punctures the medicine bottle and the bottle is partially or completely withdrawn, the medicine in the bottle flows out through the deflector holes in the deflector disc to the bottom of the deflector disc and into the atomizer along the diversion channel. This process eliminates the need to further press down on the medicine bottle to deform the soft film, making the puncture of the medicine bottle simpler and more labor-saving. The height of the medicine bottle can also be reduced, reducing both size and cost. The medicine bottle can be designed as a soft bag-like structure and stored directly in the first cavity, making the overall structure of the disposable aerosol inhalation generating device more compact.

[0020] Furthermore, the soft film and the fixed bracket separate the first cavity into a drug injection chamber, a diversion chamber and an atomization chamber, wherein the drug injection chamber is located above the soft film, the drug injection port is connected to the drug injection chamber, the diversion chamber is located between the soft film and the fixed bracket, and the atomization chamber is located below the fixed bracket; the atomization chamber is connected to the second cavity.

[0021] Furthermore, the generating device also includes a first diverter plate and a second diverter plate arranged at a distance within the first cavity; the first diverter plate is located above the second diverter plate, the fixed bracket is located above the first diverter plate, and the atomizing device is located below the second diverter plate; a first diverter hole is provided on the first diverter plate, and a second diverter hole is provided on the second diverter plate, and the first diverter hole and the second diverter hole are eccentrically staggered.

[0022] The second diversion hole is arranged above the center of the atomizing device.

[0023] By providing the first diverter plate and the second diverter plate, and distributing the first diverter hole and the second diverter hole in an eccentric and staggered manner, the falling speed of the liquid medicine is slowed down, and the influence of the liquid medicine on the generated aerosol is reduced.

[0024] Furthermore, the atomization device includes a pad, a control chip, and a battery, an atomizer sheet, and a switch electrically connected to the control chip; the pad is arranged in the first cavity and maintains a distance from the bottom of the first cavity to separate the first cavity into an electric control compartment; the battery and the control chip are arranged in the electric control compartment, the atomizer sheet is arranged outside the electric control compartment and located above the pad, and the switch is arranged on the surface of the shell.

[0025] Furthermore, the user connection end includes a nasal mask and / or a facial mask.

[0026] Furthermore, the generating device further comprises:

[0027] A sealing film, sealing the second communicating groove of the bottom box;

[0028] A fixed connecting piece connected to the outer side of the sealing film, and the fixed connecting piece is also fixedly connected to the bottom box or the partition;

[0029] a flexible connecting piece connected to the outer side of the sealing film, wherein the end of the flexible connecting piece is provided with a cantilevered curved section that bends away from the sealing film, the cantilevered curved section abuts against the fixed connecting piece and is adhered to the fixed connecting piece via a glue bonding portion located between the cantilevered curved section and the fixed connecting piece;

[0030] a pull rod disposed in the first connecting groove, one end of the pull rod being connected to the cantilevered curved section, and the other end of the pull rod extending out of the housing; and

[0031] a pull ring connected to a pull rod extending out of the housing;

[0032] Wherein, the bag is in an inflated state; the atomization outlet or the user connection end is provided with a sealing member.

[0033] A sealing film is provided at the second connecting groove to seal the bottom box, blocking the connection between the bottom box and the first cavity. This prevents cross-contamination between the first cavity and the interior of the metered-dose container before use, ensuring a sterile environment within the metered-dose container. A pull rod connects the flexible connecting piece, which in turn connects to the sealing film. Pulling the pull rod causes the flexible connecting piece to tear the sealing film, connecting the metered-dose container to the first cavity, making operation very convenient. The cantilevered curved section and the fixed connecting piece are bonded with glue, preventing unnecessary pulling on the pull rod and premature tearing of the sealing film. The fixed connecting piece and the flexible connecting piece are bonded to the outside of the sealing film, providing some protection for the film. Furthermore, the pouch is inflated, facilitating rapid filling of the pouch with aerosol. When the mist within the pouch is inhaled, the pouch deforms, with a significant contrast between the before and after deformation, making it easier to observe the pouch deformation and assess the aerosol inhalation effect.

[0034] Furthermore, the sealing film includes a first film segment, a second film segment, and a recessed portion connected between the first film segment and the second film segment; the first film segment is connected to the fixed connecting piece, the second film segment is connected to the flexible connecting piece, and the length of the second film segment is longer than that of the first film segment.

[0035] By providing a recessed portion on the sealing film, the sealing film is made easier to break, and by limiting the lengths of the first film segment and the second film segment, the second film segment with a longer length is curled and deformed along with the flexible connecting piece, so that the connecting opening between the second connecting groove and the first connecting groove is larger, which is conducive to the aerosol entering the quantitative container.

[0036] The beneficial effects of the present invention are as follows: by arranging a first cavity and a second cavity in the shell, the atomizing device is arranged in the first cavity, and the quantitative container is arranged in the second cavity, the aerosol generated by the atomizing device enters the quantitative container in the second cavity, and because the quantitative container has a soft deformable structure, after the aerosol in the quantitative container is sucked away, the soft deformable structure is compressed and deformed, and the deformation of the quantitative container can be intuitively seen through the transparent observation window, which is very convenient for judging whether the atomized inhalation amount meets the requirements.

DETAILED DESCRIPTION

[0055] The application will be further described in detail below in combination with the drawings and specific examples.

[0056] Example 1

[0057] like Figures 1-7 As shown, the disposable atomized inhalation generating device proposed in this embodiment includes: a housing 1, an atomizing device, a quantitative container and a user connection end.

[0058] The interior of the shell 1 is a hollow cavity, and a partition 4 is provided inside the shell 1 for dividing the hollow cavity into a first cavity 2 and a second cavity 3. The partition 4 is arranged upright; a first connecting groove 5 connecting the first cavity 2 and the second cavity 3 is provided on the partition 4, and the first connecting groove 5 is arranged horizontally. The shell 1 is also provided with a transparent observation window 7 for observing the second cavity 3; the transparent observation window 7 is preferably a transparent plastic plate. The shell 1 is preferably a hollow cylinder or an elliptical cylinder, and the outer side of the shell 1 is provided with anti-slip grooves 8. The shell 1 is provided with an injection port 9 and a sealing cover 10 for opening or closing the injection port 9 on the surface corresponding to the first cavity 2. The sealing cover 10 can be threadedly connected or plug-in connected to the injection port 9. It is preferably a threaded connection with better sealing performance. The injection port 9 is preferably arranged at the upper end or top of the shell 1.

[0059] The housing 1 is preferably made entirely of transparent plastic material, so that the internal structure of the housing 1 can be observed from different directions, and not only the second cavity 3 but also the first cavity 2 can be observed.

[0060] The atomizing device is disposed in the first cavity 2 of the housing 1 and is used for atomizing the medicine injected into the first cavity 2 to generate an aerosol.

[0061] The atomizer device can utilize existing technology. In this embodiment, the atomizer device includes a backing plate 11, a control chip 12, a battery 13 electrically connected to the control chip 12, an atomizer plate 14, and a switch 15. The backing plate 11 is disposed within the first cavity 2 and spaced apart from the bottom of the first cavity 2 to separate the first cavity 2 into an electrical control compartment 16. The battery 13 and control chip 12 are disposed within the electrical control compartment 16, the atomizer plate 14 is disposed outside the electrical control compartment 16 and above the backing plate 11, and the switch 15 is disposed on the surface of the housing 1. The atomizer device may also include an indicator light 17 embedded in the surface of the housing 1 and electrically connected to the control chip 12. The bottom of the housing 1 is also provided with an openable battery cover 18, which is opened to facilitate the installation of the battery 13. After the battery 13 is installed, the switch 15 is turned to the ON position, the indicator light 17 illuminates, and the control chip 12 issues an atomization command to the atomizer plate 14, which then atomizes the medication into an aerosol. When the switch 15 is pushed to the OFF position, the indicator light 17 goes out and the atomizing plate 14 stops atomizing.

[0062] The quantitative container is arranged in the second cavity 3 of the shell 1. The quantitative container has a soft deformable structure, and the soft deformable structure is located within the observation window range of the transparent observation window 7; the quantitative container is also connected to the first cavity 2 and is used to collect the aerosol in the first cavity 2.

[0063] The user connection terminal is disposed outside the housing 1 and communicates with the quantitative container. The user connection terminal includes a nasal mask 19 and / or a facial mask. To ensure sealing and sterility, the atomization outlet 23 or the user connection terminal is provided with a seal. The seal can be a puncturable or tearable sealing film 20.

[0064] The aerosol generated by the atomizer is filled into a metered-dose container. The user inhales the aerosol in the metered-dose container using a nasal mask 19 or a facial mask. After the aerosol in the metered-dose container is inhaled, the soft, deformable structure of the metered-dose container contracts and deforms inward, commonly known as "suffocation." Medical staff or patients can determine whether the inhaled amount of aerosol inside the metered-dose container meets the required level by observing the degree of deformation of the soft, deformable structure. For example, when the soft, deformable structure is completely deformed to the point where it can no longer deform, it means that the aerosol in the metered-dose container that can be inhaled has been completely inhaled.

[0065] like Figure 3 As shown, the dosing container includes a connected hard base box 21 and a soft pouch 22. The pouch 22 is a soft, deformable structure. The base box 21 is provided with a second communication groove 6 and an atomization outlet 23. The second communication groove 6 is connected to the first communication groove 5, and the atomization outlet 23 is connected to the user connection terminal. The connection between the hard base box 21 and the soft pouch 22 maintains effective communication between the dosing container, the first communication groove 5, and the user connection terminal, which facilitates the entry of aerosol generated by the atomization device into the base box 21 and pouch 22.

[0066] There are multiple pouches 22, which are connected in series and in sequence. In this embodiment, there are three pouches 22, which are vertically connected in series and are all located above the bottom box 21. The volumes of the three pouches 22 can be the same or increase in size from top to bottom.

[0067] The amount of aerosol inhaled is determined by the deformation of the pouch 22. Storing aerosol in series with pouches 22 not only achieves partitioned storage of aerosol but also facilitates the deformation of a single pouch 22. The number of deformed pouches 22 also allows for determining the remaining amount of aerosol in the quantitative container, making the determination more intuitive and clear.

[0068] like Figures 3-7 As shown, the generating device also includes a medicine bottle 24 and a puncture device; the shell 1 is provided with a medicine injection port 9 and a sealing cover 10 for opening or closing the medicine injection port 9 on the surface corresponding to the first cavity 2; the medicine bottle 24 stores medicine; the puncture device is arranged in the first cavity 2, and is used to puncture the medicine bottle 24 entering the first cavity 2 from the medicine injection port 9, so that the medicine in the medicine bottle 24 is injected into the first cavity 2.

[0069] Medicine bottle 24 comprises a bottle body and a bottle cap, which is sealed to the bottle body and is a puncturable structure, such as a rubber cap or a plastic cap. The bottle body is a glass bottle. The medicine stored in the bottle is sufficient for at least one person. Of course, medicine bottle 24 can also be a puncturable plastic bottle or plastic bag structure.

[0070] like Figure 5 、 6 As shown, the puncture device includes: a soft film 25, a fixing bracket 27, and a puncture needle 29.

[0071] The soft plastic sheet 25 is a circular ring structure with a through hole 26 provided in the center thereof. The outer edge of the soft plastic sheet 25 is fixed to the inner wall of the first cavity 2 .

[0072] The fixing bracket 27 is arranged below the soft film 25 and is fixedly connected to the inner wall of the first cavity 2. The fixing bracket 27 is provided with a guide channel 28. The fixing connection method can be glue bonding.

[0073] The lower end of the puncture needle 29 is connected to the fixed bracket 27, and the diversion channels 28 are evenly and symmetrically distributed along the circumference of the puncture needle 29. The upper end of the puncture needle 29 is a sharp spike portion, which is inserted into and engages with the through-hole 26 of the soft plastic sheet 25 and extends above the soft plastic sheet 25. The spike portion engages with the through-hole 26 of the soft plastic sheet 25 to seal the drug injection chamber 32 when the medicine bottle 24 is not inserted. The drug injection chamber 32 is located above the soft plastic sheet 25 in the first cavity 2.

[0074] like Figure 7 As shown, when the medicine bottle 24 is inserted downward into the medicine injection chamber 32 through the medicine injection port 9, the medicine bottle 24 is punctured by the action of the sharp thorn part. If the medicine bottle 24 continues to be pushed downward, the edge of the medicine bottle 24 pushes down the soft plastic sheet 25, and the through hole 26 of the soft plastic sheet 25 deforms downward and expands, and the through hole 26 expands. The medicine in the medicine bottle 24 flows downward to the atomizing sheet 14 of the atomizing device, and is covered with the sealing cover 10 to start atomization.

[0075] Another way of using it is that the medicine bottle 24 is inserted downward into the medicine injection chamber 32 through the medicine injection port 9, and after the medicine bottle 24 is pierced by the action of the sharp thorn part, the medicine bottle 24 is directly pulled out upward to separate the medicine bottle 24 from the puncture needle 29, and the sealing cover 10 is covered. The medicine in the medicine bottle 24 flows out into the medicine injection chamber 32, and the medicine in the medicine injection chamber 32 slowly seeps through the gap at the fitting place of the puncture needle 29 and the through hole 26 of the soft plastic film 25 to the atomization sheet 14 of the atomization device below.

[0076] like Figure 3As shown, the soft film 25 and the fixed bracket 27 divide the first cavity 2 into a drug injection chamber 32, a diversion chamber 33 and a mist chamber 34, wherein the drug injection chamber 32 is located above the soft film 25, the drug injection port 9 is connected to the drug injection chamber 32, the diversion chamber 33 is located between the soft film and the fixed bracket 27, and the mist chamber 34 is located below the fixed bracket 27; the mist chamber 34 is connected to the second cavity 3.

[0077] Combined with attachment Figure 3 、 5 As shown, the generating device also includes a first diverter plate 35 and a second diverter plate 36 spaced apart within the first cavity 2; the first diverter plate 35 is located above the second diverter plate 36, the fixing bracket 27 is located above the first diverter plate 35, and the atomizing device is located below the second diverter plate 36; a first diverter hole 37 is provided on the first diverter plate 35, and a second diverter hole 38 is provided on the second diverter plate 36, and the first diverter hole 37 and the second diverter hole 38 are eccentrically offset. The second diverter hole 38 is provided above the center of the atomizing device. By providing the first diverter plate 35 and the second diverter plate 36, and the eccentrically offset distribution of the first diverter hole 37 and the second diverter hole 38, the falling speed of the liquid medicine is slowed down, and the impact of the liquid medicine on the generated aerosol is reduced.

[0078] To achieve sterility, the disposable aerosol inhalation generating device of this embodiment also includes a sterile packaging bag. The sterile packaging bag has three independent sub-packaging bags, each containing the housing 1, the user connection end, and the medicine bottle 24. The housing 1 and its internal aerosol device, quantitative container, puncture device, etc. are placed as a whole product in the sterile packaging bag.

[0079] Example 2

[0080] like Figures 8-17 As shown, the invention proposes a disposable atomized inhalation generating device, the structure of which is substantially the same as that of Example 1, except that:

[0081] The puncture device also includes a guide plate 30 that is fixedly mounted on the puncture needle 29, and is provided with a guide hole 31 on the guide plate 30; the guide plate 30 is coaxially nested in the through hole 26 of the soft plastic sheet 25 and abuts against the hole wall of the through hole 26. Compared with Example 1, the guide plate 30 of this embodiment is equivalent to an expanded diameter section provided on the puncture needle 29 of Example 1, which can better fit the soft plastic sheet 25. Of course, although the provision of the guide hole 31 on the guide plate 30 is not conducive to the closure of the drug injection chamber 32, during the puncture of the medicine bottle 24, there is no need to push the soft plastic sheet 25, and the medicine in the drug injection chamber 32 can flow downward along the guide hole 31 into the guide chamber 33. It is particularly suitable for the structure of a soft medicine bottle 24.

[0082] like Figure 12 、 13As shown, the generating device of this embodiment further includes: a sealing film 39 , a fixed connecting piece 43 , a flexible connecting piece 45 , a pull rod 48 and a pull ring 49 .

[0083] The sealing film 39 seals the second communication slot 6 of the bottom box 21. While the second communication slot 6 in Example 1 provides communication between the first and second cavities 2 and 3, the sealing film 39 in this embodiment seals the second communication slot 6, blocking the connection between the first and second cavities 2 and 3. This ensures a sterile environment in the second cavity 3. Of course, the disposable aerosol inhalation generating device should undergo sterilization treatment before shipment to ensure that at least the second cavity 3 is sterile.

[0084] The fixed connecting piece 43 is connected to the outer side of the sealing film 39, and the fixed connecting piece 43 is also fixedly connected to the bottom box 21 or the partition 4; the connection method can adopt a fixing screw 44, and the fixing connecting piece 43 is fixed to the partition 4 using the fixing screw 44. After connection, the fixed connecting piece 43 is bent into an arc.

[0085] The flexible connecting piece 45 is connected to the outside of the sealing film 39 and is in the form of an elongated strip. The end of the flexible connecting piece 45 is provided with a cantilevered curved section 46 that bends away from the sealing film 39. The cantilevered curved section 46 abuts against the fixed connecting piece 43 and is bonded to the fixed connecting piece 43 via a glue bonding portion 47 located between the cantilevered curved section 46 and the fixed connecting piece 43. The glue bonding portion 47 is a dot-shaped structure with a diameter of less than 5 mm. The majority of the flexible connecting piece 45 is bonded to the outside of the sealing film 39, while a smaller portion, serving as the cantilevered curved section 46, is bonded to the fixed connecting piece 43.

[0086] The pull rod 48 is disposed in the first connecting groove 5, with one end of the pull rod 48 connected to the cantilevered curved section 46, and the other end of the pull rod 48 extending outside the shell 1. The portion where the pull rod 48 is connected to the cantilevered curved section 46 should be on the side of the glue bonding portion 47 facing away from the sealing film 39, so that when the pull rod 48 is pulled, the cantilevered curved section 46 and the fixed connecting piece 43 can be separated first, and then the sealing film 39 can be torn open. The fixed connection portion between the pull rod 48 and the cantilevered curved section 46 and the glue bonding portion 47 are respectively located at the two ends of the cantilevered curved section 46, making the glue bonding portion 47 easier to break, thereby achieving the separation of the cantilevered curved section 46 and the fixed connecting piece 43 of the flexible connecting piece 45. The pull ring 49 is connected to the pull rod 48 extending outside the shell 1.

[0087] The pouch 22 is in an inflated state, and a sealing member is provided at the atomization outlet 23 or the user connection end. The sealing member is a sealing film 20, and the user connection end is preferably a nasal mask 19, and the sealing film 20 is provided at the end of the nasal mask 19.

[0088] By providing a sealing film 39 at the second connecting groove 6 to seal the bottom box 21, the connection between the bottom box 21 and the first cavity 2 is blocked, thereby preventing cross-contamination between the first cavity 2 and the interior of the quantitative container before use, thereby ensuring a sterile environment inside the quantitative container. The flexible connecting piece 45 is connected by a pull rod 48, and the flexible connecting piece 45 is used to connect the sealing film 39. By pulling the pull rod 48 through the pull ring 49, the sealing film 39 can be torn open and torn under the action of the flexible connecting piece 45, so that the quantitative container is connected to the first cavity 2, which is very convenient to operate. The cantilevered curved section 46 and the fixed connecting piece 43 are adhered with a glue bonding portion 47 to prevent the pull rod 48 from being subjected to unnecessary pulling, which may cause the sealing film 39 to be torn prematurely. After the fixed connecting piece 43 and the flexible connecting piece 45 are adhered, they are located outside the sealing film 39, which also plays a certain protective role for the sealing film 39. In addition, the pouch 22 is in an inflated state, which is also conducive to the aerosol quickly filling the entire pouch 22. When the mist in the pouch 22 is inhaled, the pouch 22 is deformed. The contrast between the pouch 22 before and after deformation is large, which is also convenient for observing the deformation of the pouch 22 and judging the atomization inhalation effect.

[0089] like Figure 14 As shown, the sealing film 39 includes a first film segment 40, a second film segment 41, and a recessed portion 42 connecting the first and second film segments 40, 41. The first film segment 40 is connected to a fixed connecting piece 43, and the second film segment 41 is connected to a flexible connecting piece 45. The second film segment 41 is longer than the first film segment 40. The recessed portion 42 in the sealing film 39 makes the sealing film 39 easier to break. By limiting the length of the first and second film segments 40, 41, the longer second film segment 41 curls and deforms along with the flexible connecting piece 45, thereby increasing the diameter of the connection between the second connecting groove 6 and the first connecting groove 5, thereby facilitating the entry of aerosol into the quantitative container.
