Description

Technical Field

[0001] The utility model relates to the technical field of atomizing devices, in particular to a detachable aerosol inhalation dosing device. Background Art

[0002] Different from oral and injection administration, nasal / oral inhalation administration is a very special brain-targeted and lung-targeted administration route, which has obvious clinical advantages in preventing and treating diseases of the central nervous system and respiratory system. (1) Studies have confirmed that there is a direct anatomical channel between brain tissue and nasal cavity. Nasal inhalation administration can bypass the blood-brain barrier and directly deliver drugs to the brain non-invasively, that is, drugs can reach the central nervous system through the olfactory epithelium or respiratory epithelium of the nasal mucosa and quickly enter the brain tissue; the nose-brain connection can also activate peripheral nasal chemosensory neurons, trigger and regulate the olfactory-amygdala neural circuit to achieve therapeutic effects without the need for the drug itself to enter the brain tissue. Regardless of the mechanism, its characteristics are to avoid the blood-brain barrier, alveolar blood-gas barrier, liver first-pass effect and gastrointestinal metabolism, so the required dose is the lowest (10-6-10-12g), the onset is the fastest (a few seconds), and the systemic toxicity and side effects are the lowest. (2) Studies have confirmed that pulmonary inhalation is also a good route of drug administration. The characteristics of lung-targeted drugs are large absorption surface area, thin alveolar gas-blood barrier, and rich capillary network, which can avoid gastrointestinal metabolism and liver first-pass effect; the dosage required is lower than that of oral and injection administration, the onset is faster, the systemic toxicity and side effects are small, and the compliance is good. (3) Studies have confirmed that other non-central nervous system and non-respiratory system drugs can also achieve better prevention and treatment effects of diseases through nasal / oral atomization inhalation administration, such as peptide diabetes drugs that require frequent injections, osteoporosis drugs, hormone drugs, and other oral and injectable drugs that require rapid onset. Improving them into inhalation dosage forms to meet the needs of users has very practical significance.

[0003] Respiratory inhalation compositions can be divided into quantitative inhalation aerosols, dry powder inhalers, liquid atomized inhalers and soft mists. They all require a special atomizing device to be paired with it for drug administration, and inhalation through the deep respiratory tract, cavity, mucosa, etc. exerts local or systemic therapeutic effects to achieve the purpose of painless, rapid and effective treatment. Among them, the liquid formula of quantitative inhalation aerosol contains a low-boiling propellant. The user shakes the atomizing device before use to produce internal pressure spray. The atomization and spraying must be coordinated and reversed at the same time. Many users, especially children and the elderly, find it difficult to do so. Therefore, the precise atomization and precise inhalation of the drug are affected, resulting in unsatisfactory therapeutic effects. The inhalation strength and breathing habits of each user are different. The same atomizer and atomizing device will have different inhalation doses and different drug deposition sites for different users, which also affects the therapeutic effect. Liquid aerosols, dry powder inhalers and soft mists have the same problem of inaccurate atomization doses, inhalation doses and deposition sites.

[0004] In view of this, it is necessary to provide an atomization device that can accurately atomize and accurately inhale aerosols to solve the problem of accurate atomization inhalation. Utility Model Content

[0038] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0039] See also Figures 1 to 11As shown, the utility model provides a detachable aerosol inhalation dosing device, comprising a base body 10, an atomizing device 20 for atomizing medicine to generate an aerosol, and an aerosol storage container 3. The interior of the mist storage container 3 defines a cavity for collecting aerosols, and the mist storage container 3 can be detachably combined with the seat body 10 for the user to inhale the aerosol; wherein, the top of the mist storage container 3 has an aerosol outlet for the user to inhale the aerosol, and its bottom is closed to limit the downward flow of the aerosol; and the bottom of the mist storage container 3 has an opening 32b for the atomization device 20 to input the aerosol into the cavity; through the above structure, the user can directly take the mist storage container 3 to inhale the aerosol, which is simple and convenient and the dosage is accurate. wherein, the particle size range of the aerosol is configured to be able to be suspended in the cavity for a period of time under gravity conditions, thereby ensuring the uniformity of the aerosol particles and avoiding the problem of insufficient uniformity of the aerosol generated by some atomization devices 20 in the prior art, such as most of the existing drug atomization devices directly atomize the aerosol after adsorbing the drug in the liquid storage cavity, which may carry some large particles of drug liquid that are not completely atomized, affecting the uniformity of the aerosol and further affecting the deposition position. In the present technical solution, only aerosols that meet the particle size range can enter the mist storage container 3, while those aerosols that do not meet the particle size range will be retained in the atomization device 20 for continued atomization, thereby ensuring the uniformity of the aerosol and the therapeutic effect of the drug.

[0040] Furthermore, the particle size range of the aerosol is 0.1-100 μm to ensure that the aerosol can be suspended in the cavity. Preferably, the particle size range of the aerosol is 0.1-20 μm, and more preferably 1-10 μm, which can enter and deposit in the user's nasal cavity and lungs to ensure the therapeutic effect of the drug. Of course, aerosols with a diameter less than or equal to 2.5 μm can be suspended in the air for a long time, have a long residence time in the mist storage container, and have a long transportation distance, and can directly enter the user's bronchioles 42 and alveoli, thereby ensuring the therapeutic effect of the drug. Fig.11 This is a distribution diagram of the aerosol particle size range of an embodiment of the present application, wherein the aerosol particle size range is most concentrated within 1-6 microns and is most suitable for being inhaled into the respiratory system by the user and deposited on the respiratory system mucosa for the treatment of local nasal and lung diseases. It can also directly affect the brain organs through the nose-brain pathway to treat central nervous system diseases, and can also be absorbed into the blood circulation system through the nasal mucosa and alveoli to treat systemic diseases.

[0041] See also Figures 2 to 8As shown, the atomizing device 20 is electrically connected to the base body 10 via a detachable electrical coupler, so that the atomizing device 20 and the base body 10 are modularly separated and arranged for easy disassembly, interchangeability, and cleaning. The detachable electric coupler includes a first electrode and a second electrode, one of which is coupled to the atomizing device, and the other is coupled to the seat body; further, in order to achieve detachable separation of the two, in the present embodiment, the atomizing device 20 is also connected to the seat body 10 by means of a threaded connection component 70, and the threaded connection component 70 includes a first connector 71 and a second connector 72 that are detachably connected to each other; wherein, the first connector 71 is coupled to the atomizing device 20, and the second connector 72 is coupled to the seat body 10, and the second connector 72 is configured as a threaded seat, and the first connector 71 has a threaded head that is adapted to the threaded seat; the first electrode is arranged in the threaded seat, and the second electrode is arranged in the threaded head, and when the atomizing device 20 is screwed together by means of the threaded head and the threaded seat, the first electrode and the second electrode are in contact to achieve circuit connection, thereby connecting the atomizing device 20 with the circuit system in the seat body 10.

[0042] See also Figure 7 As shown, the atomization device 20 includes a hollow tube 21, which has a receiving cavity inside to receive the medicine, and the tube wall is marked with volume scale lines; and an atomization core 22, which is arranged in the receiving cavity to atomize the medicine to generate an aerosol; the top opening of the hollow tube 21 is set so that the atomized aerosol flows out from the top and then enters the mist storage container 3. Further, the atomization core 22 includes: an adsorbent 222, which is suitable for adsorbing the medicine atomizer in the receiving cavity; a heating element 223, which is suitable for generating an aerosol with the above-mentioned particle size range from the medicine atomizer adsorbed by the adsorbent 222; and an air guide tube 221, which is arranged in the hollow tube 21 along the axial direction to transport the aerosol. In order to ensure the atomization particle size range of the aerosol, the adsorbent 222 is made of porous material, such as porous ceramics, cotton, non-woven fabrics, etc., which can adsorb the drug atomizer in the hollow tube 21. The heater can be a ceramic heating element 223, which can heat the drug atomizer to generate an aerosol. The air guide tube 221 defines an atomization chamber and a delivery chamber, wherein the adsorbent 222 and the heating element are both received in the atomization chamber, and the heating element is connected to the second electrode so that the first connecting member 71 and the second connecting member 72 can be connected together to power the heating element. A through hole is provided on the side wall of the atomization chamber on the air guide tube 221 so that the drug solution enters the atomization chamber and is adsorbed by the adsorbent 222.

[0043] When in use, it is only necessary to take a set amount of medicine, such as by using a quantitative tool to absorb, or by using isolation paper, quantitative bottles, etc. for quantitative packaging, and then pour the quantitative medicine into the hollow tube 21 and store it for quantitative atomization, and then control the atomization time of the medicine by controlling the atomization core 22 to generate the required dose of aerosol, and let the aerosol enter the aerosol storage container 3 for the user to inhale. In this way, it can ensure that the medicine is accurately atomized each time, and the two steps of atomization and inhalation can be separated to ensure accurate inhalation of each dose, and it can also avoid the aerosol being inhaled by the user in time due to the asynchronous spraying and inhalation, which causes waste / inaccuracy and deviation of the aerosol deposition site in the respiratory system, thereby ensuring accurate treatment of the site. The utility model can quantitatively collect the aerosol generated by the atomizing core 22 through the mist storage container 3, so as to achieve the effect of separate implementation of the three steps of precise atomization, precise storage and precise inhalation, and solves the problem that other existing atomizing devices 20 absorb drugs while atomizing, which requires the user to have good breathing coordination, otherwise it is easy to cause drug waste, inaccuracy, and / or problems with drug inhalation coordination for children and some special patients. In addition, the drug delivery device adopts a modular design, so that the mist storage container can be separated from the atomizing seat body, which is convenient for users to use.

[0044] In this embodiment, the mist storage container 3 is made of transparent material, such as glass, PVC, etc., so that the user can observe the amount of aerosol generated in the mist storage container 3; further, the side wall of the mist storage container 3 is provided with volume scale lines so that the user can select the dose of aerosol generated. Figure 1 to Figure 2 As shown, in order to make the aerosol stay in the cavity better, the upper half of the mist storage container 3 has a tapered portion 33 that gathers the aerosol in the cavity. At the same time, in order to prevent the aerosol from escaping into the air from the top port, a container cover 9 is attached to the mouthpiece 31 of the mist storage container 3. Fig.10 As shown, at least one suction nozzle 31 is provided on the container cover 9 for the user to inhale the aerosol; wherein the suction nozzle 31 can be provided with one so that the user can inhale through the mouth; of course, two small suction nozzles 31 can also be provided so that the user can inhale through the nasal cavity; it can also be designed as three suction nozzles 31 for simultaneous inhalation of the nasal cavity and the mouth; it can also be designed as a pacifier and a drinking straw to induce infants and children to inhale, and the specific form can be flexibly designed according to the use requirements. In this embodiment, the suction nozzle 31 is detachably connected to the mist storage container 3, and an integrated design can also be adopted in other embodiments.

[0045] The bottom of the mist storage container 3 is detachably connected with a sealing plug 32, and the opening 32b is formed on the sealing plug 32. The sealing plug 32 can limit the aerosol from flowing downward, so that the aerosol is suspended in the cavity, which is convenient for the user to pick up the mist storage container 3 and inhale the aerosol. Preferably, the sealing plug 32 is made of food-grade silicone material, which has the advantages of good flexibility and long service life. Moreover, the sealing plug 32 can not only seal the bottom of the mist storage container 3, but also protect the bottom of the mist storage container 3 to avoid collision and damage to the mist storage container 3 when the mist storage container 3 is placed.

[0046] See also Figures 2 to 5 As shown, further, the seat 10 has a limiting cavity 15, and the atomizing device 20 is combined in the limiting cavity 15 and coincides with the central axis of the limiting cavity 15; the bottom of the mist storage container 3 is received in the limiting cavity 15 to limit the horizontal movement of the mist storage container 3, and also ensure the stability of the mist storage container 3 placed on the seat 10, to prevent the mist storage container 3 from deviating from its position during the atomization process, affecting the aerosol entering the cavity, or the volume measurement reading deviation, or falling and damage. In addition, the sealing plug 32 defines a hollow cover 32a extending toward the inside of the cavity, so that the mist storage container 3 can accommodate the atomizing device 20 when it is combined with the seat 10. Furthermore, the opening 32b is formed on the side wall of the hollow cover 32a. This structure enables the bottom wall of the mist storage container 3 to fit on the bottom wall of the limiting cavity 15, thereby forming a sealing structure, so that the aerosol generated by the atomization core 22 can directly enter the containing cavity of the mist storage container 3 from the opening 32b on the side wall of the hollow cover 32a, thereby reducing the overflow of the aerosol; at the same time, the mist storage container 3 can also be limited, so that the mist storage container 3 is placed stably. Preferably, the opening 32b is arranged at a position closer to the bottom of the hollow cover 32a, so that the generated aerosol can gather from the bottom of the cavity and push the aerosol upward in parallel, gradually filling the cavity, thereby ensuring that the aerosol volume scale reading is accurate; in addition, the top of the hollow cover 32a is higher than the height of the atomizing device 20, and the inner diameter of the hollow cover 32a is larger than the outer diameter of the atomizing device 20, thereby leaving a channel between the hollow cover 32a and the atomizing device 20 to ensure the output of the aerosol.

[0047] See also Figure 2 and Fig. 9As shown, the seat body 10 is also provided with an airflow generating device 40, and the airflow generating device 40 is configured to generate an airflow to transport the aerosol generated by the atomizing device 20 to the mist storage container 3, so as to improve the fluidity and density uniformity of the aerosol and avoid clogging in the atomizing core 22. Specifically, the airflow generating device 40 includes an air pump 41, and the air pump 41 is connected to the atomizing device 20 through an air pipe 42. The seat body 10 is also provided with a lower connecting seat engaged with the second connecting member 72, and the lower connecting seat is provided with a through hole for connecting the air pipe 42 and the atomizing core 22. The above structure can ensure that the airflow generating device 40 is stably connected to the seat body 10, and at the same time, it does not affect the detachable connection of the atomizing device 20.

[0048] The device also includes an operating device 5, which includes: an operating unit 51, which is configured to respond to the user's operation to control the operation of the atomizing device 20 and the atomization time and dosage; and a display unit 52, which is used to display the working state of the atomizing device 20. The operating unit 51 is configured as an operating button, which is arranged on the upper surface of the seat body 10 so that the user can touch it to start the atomizing core 22 to atomize and generate aerosol; the display unit 52 is configured as an LED light, which can display the working state of the atomizing core 22. Further, the device also includes a power source 6, which is horizontally arranged on the seat body 10 to supply power to the atomizing device 20. The power source 6 is a battery, which is arranged at the bottom of the seat body 10. Preferably, the battery is a rechargeable battery, and a rechargeable interface 8 is also provided on the seat body 10 to charge the battery, thereby ensuring the endurance of the device and facilitating portability.

[0049] See also Figures 1 to 9 As shown, the structure of the seat body 10 is a column structure. The seat body 10 includes an outer shell 11, a top cover 12, a bottom cover 13 and an inner carrier 14. The inner carrier 14 is attached to the seat body 10. The top cover 12 and the bottom cover 13 are respectively attached to the upper and lower ends of the outer shell 11 to fix the inner carrier 14 to the outer shell 11. The battery and the air pump 41 are respectively arranged on both sides of the bottom of the inner carrier 14. The battery is used to power the air pump 41 and the atomization core 22. A PCB board is also arranged on the inner carrier 14. The operation buttons, the display part 52, the air pump 41, the battery and the second connecting member 72 are all electrically connected to the PCB board. The display part 52 includes a plurality of LED colored lamp beads arranged on the PCB board, and an annular lampshade. The annular lampshade is arranged between the upper end cover and the inner carrier 14, and has the same outer diameter as the limiting cavity 15, thereby improving the overall aesthetics and compactness of the seat body 10.
