Description

Technical Field

[0001] This utility model relates to medical equipment and consumer electronics products, specifically to a portable ultrasonic liquid atomizing inhalation device. Background Technology

[0002] The principle of ultrasonic atomization is to use ultrasonic vibrations to generate pressure waves through a liquid, thereby breaking the liquid into tiny droplets. The ultrasonic transducer inside the ultrasonic atomizer converts electrical energy into high-frequency mechanical vibrations. When the liquid surface is subjected to ultrasonic vibrations, periodic pressure changes occur. Localized negative pressure areas cause tiny bubbles to form inside the liquid. These bubbles continuously expand and contract. As the bubbles expand to a certain extent, they rupture due to the excessive internal and external pressure difference. The instantaneous high-pressure wave generated by the rupture ejects the liquid from the bubbles, forming numerous tiny droplets. During the rupture process, the liquid is cut into extremely fine water mist. Taking advantage of this effect, ultrasonic atomization is often used for air humidification, drug atomization, and other applications.

[0003] Compared to the main methods of drug administration for patients with traditional respiratory diseases and other diseases (injectable drugs: intramuscular injection or intravenous infusion, the drug indirectly reaches the lesion; tablets, pills, and traditional Chinese medicine decoctions: oral administration into the digestive system, the drug indirectly reaches the lesion), nebulized drug solution can directly act on the lesion, improving the treatment effect.

[0004] Existing methods of liquid drug nebulization: (1) It is carried out in hospitals or other treatment facilities. Its inconvenience is that patients must go to a designated place (such as a hospital) to achieve liquid drug nebulization inhalation, which has limitations in use; (2) There are also some simple nebulization devices on the market, but they have inconveniences in use: they are mostly integrated structures, making it inconvenient to change the medication; the inhalation method of liquid drug after nebulization is singular; and the air intake and dosage cannot be adjusted.

The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose. Example

[0048] Please see Figures 1 to 16 This embodiment provides a portable ultrasonic liquid atomizing inhalation device, including an atomizing component 100 and a battery component 200. The atomizing component 100 and the battery component 200 are connected magnetically. After the two components are attracted together, the spring electrode 8 on the battery component 200 is compressed by the corresponding metal single electrode 21 on the atomizing component 100, thereby achieving a closed-loop power supply. Figure 2 and Figure 3 As shown;

[0049] Specifically, such as Figure 5 , Figure 6 and Figure 7 As shown, the battery assembly 200 is composed of a battery casing 1, a battery bracket 2, a lithium battery 5, a control PCB board 3, a charging PCB board 4, a button 6, a panel 9, a magnet 7, a spring electrode 8, and a label 10. The bottom of the battery casing 1 is provided with a charging interface, which is a universal Telephone-C interface 41.

[0050] The battery housing 1 has a battery bracket 2 installed inside. The battery bracket 2 is an engineering plastic part. A charging PCB board 4 is installed at the bottom of the battery bracket 2. Correspondingly, there is an opening at the bottom of the battery housing 1 for connecting to the battery-C interface 41 to achieve charging. In addition, there is a label 10 on the outside of the bottom side wall of the battery housing 1 for warning purposes.

[0051] Inside the battery casing 1, in front of the battery bracket 2, there is a control PCB board 3. Between the control PCB board 3 and the battery bracket 2, there is a lithium battery 5. A panel 9 is embedded in the front of the battery casing 1. A button 6 is installed on the panel 9. The button 6 is used to adjust the device. Above the button 6, there is a digital display tube 31 for display.

[0052] Two spring electrodes 8 are provided at the top center of the battery holder 2, and two magnets 7 are provided on the front and rear sides of the spring electrodes 8. The spring electrodes 8 and the magnets 7 are embedded in the slot of the battery holder 2 by interference fit.

[0053] When assembling the battery assembly 200, first press the two standard metal spring electrodes 8 into the two cylindrical slots in the middle of the battery bracket 2. Then, attach the lithium battery 5 to the back of the control PCB board 33 with double-sided sponge adhesive. Next, insert the lithium battery 5 and the control PCB board 3 into the rectangular blind hole slot on the lower end of the battery bracket 2. At the same time, insert the charging PCB board 4 into the bottom of the cylindrical tube of the battery bracket 2 and constrain and fix the other end of the control PCB board 3. After tightening the charging PCB board 4 with screws, connect the spring electrodes 8 and the charging PCB board 4 to the control PCB board 3 by soldering.

[0054] Install the battery bracket 2 into the battery housing 1. Secure the battery bracket 2 with four self-tapping screws at the opening of the battery housing 1. The button 6 is made of engineering plastic. Place the button 6 into the corresponding irregular groove on the side of the battery housing 1. Insert the panel 9 into the groove on the side of the battery housing 1 to constrain and fix the button 6 and ensure that the button 6 can be pressed flexibly. The panel 9 is made of transparent PC material and has high-adhesion 3M double-sided adhesive on the back.

[0055] Four magnets 7 are pressed into the four corresponding cylindrical slots on the outer end face of the battery holder 2. The label 10 is made of transparent PVC material, silk-screened and with single-sided adhesive. The label 10 is pasted on the bottom of the battery casing 1.

[0056] The four circular rare earth material magnets 7 and metal material spring electrodes 8 of the battery assembly 200 are respectively embedded in the corresponding structural slots of the plastic battery bracket 2 in an interference fit manner. The two spring electrodes 8 are respectively connected to the control PCB board 3 located below the battery bracket 2 by wires to form the battery bracket 2 assembly. After the battery bracket 2 assembly is installed into the plastic battery shell 1, it forms a trapezoidal groove.

[0057] like Figure 4 , Figure 8 and Figure 9 As shown, the atomizing assembly 100 consists of a mouthpiece top cover 12, an air regulating ring 11, a drug delivery bottle 23, a mouthpiece bottom cover 19, a water-guiding cotton swab 16, a water-guiding cotton swab support 17, a tightening spring 18, a single electrode 20, a magnet 21, and an atomizing plate assembly 14.

[0058] The upper cover 12 and the lower cover 19 of the suction nozzle are fixed by screws. The lower cover 19 of the suction nozzle is connected to the administration bottle 23 by threads. The threaded installation makes it easy to disassemble the administration bottle 23 from the lower cover 19 of the suction nozzle, thereby facilitating the replacement or addition of medication. The administration bottle 23 is made of medical glass and is screwed to the lower cover 19 of the suction nozzle by its bottle mouth threads. The upper cover 12 and the lower cover 19 of the suction nozzle are made of food-grade engineering plastic. A medicine bottle sealing gasket 22 is designed between the lower cover 19 of the suction nozzle and the mouth of the administration bottle 23 to improve the sealing effect. The medicine bottle sealing gasket 22 is made of food-grade silicone.

[0059] The lower end of the mouthpiece of the mouthpiece cover 12 is designed with an annular groove. There are two symmetrical "I"-shaped air inlets on the side of the annular groove. The air regulating ring 11 is fitted into the annular groove on the mouthpiece cover 12. The air regulating ring 11 is made of silicone. In an elastic state, the air regulating ring 11 is fitted into the annular groove of the mouthpiece cover 12 from one side of the mouthpiece. The side of the air regulating ring 11 is also designed with symmetrical "I"-shaped hollow grooves. Rotating the air regulating ring 11 can adjust the air intake when inhaling the medicine mist.

[0060] The water-conducting cotton swab 16 is made of chemical fiber and is placed in the water-conducting cotton swab holder 17. The water-conducting cotton swab holder 17 is made of food-grade engineering plastic. A compression spring 18 is designed at the bottom of the water-conducting cotton swab holder 17. The spring 18 pushes the water-conducting cotton swab 16 upward to ensure that the water-conducting cotton swab 16 is always in close contact with the atomizing plate assembly 14. The two sides of the water-conducting cotton swab holder 17 are designed with "1"-shaped hollow grooves to ensure that the medicine is absorbed by the water-conducting cotton swab 16 and transferred to the atomizing plate assembly 14. The water-conducting cotton swab holder 17 is installed at the center of the upper cover 12 and the lower cover 19 of the mouthpiece and is clamped and fixed by the two. Moreover, the atomizing plate assembly 14 is located directly above the water-conducting cotton swab holder 17.

[0061] The atomizing plate assembly 14 is a piezoelectric ceramic assembly, which is placed in the annular shallow groove protruding from the lower cover 19 of the nozzle. The upper side of the atomizing plate assembly 14 is designed with an upper atomizing plate sealing gasket 13 and the lower side is a lower atomizing plate sealing gasket 15. The upper and lower sealing gaskets ensure the elasticity of the atomizing plate assembly 14 during ultrasonic vibration, and ensure that the medicine and medicine mist residue do not enter the interior of the atomizing assembly 100 to avoid short circuit of power supply. The upper atomizing plate sealing gasket 13 and the lower atomizing plate sealing gasket 15 are both made of food-grade silicone material.

[0062] After the plastic mouthpiece top cover 12 and mouthpiece bottom cover 19 are combined, the atomizing component 100 forms a trapezoidal protrusion. Below the trapezoidal protrusion, corresponding to the positions of the magnet 7 and the spring electrode 8, there are magnets 21 and single electrodes 20 respectively. When the four magnets 7 of the battery component 200 are attracted to the four magnets 21 of the atomizing component 100, the trapezoidal protrusion of the atomizing component 100 and the trapezoidal groove of the battery component 200 are fitted with a gap, and the atomizing component 100 is constrained and fixed in the groove of the battery component 200.

[0063] The four cylindrical iron magnets 21 and two iron single electrodes 20 of the same specification of the atomizing component 100 are also fitted into the corresponding structural slots on the outer end face of the plastic mouthpiece cover 19 in an interference fit manner. At the same time, the two spring electrodes 8 in the battery component 200 are compressed and contacted by the two single electrodes 20 on the atomizing component 100 to form a power supply connection.

[0064] The two single electrodes 20 and the four magnets 21 are all made of carbon steel. After embossing and electroplating, they are embedded into the corresponding slots of the nozzle cover 19 using an interference fit process. The two single electrodes 20 are respectively connected to the positive and negative electrodes of the atomizing plate assembly 14 by wires and solder.

[0065] like Figure 10 and Figure 11 As shown, the atomizing plate assembly 14 consists of three parts: electrode plate 24 (made of stainless steel 304), piezoelectric ceramic 25 (made of piezoelectric ceramic material), and atomizing steel plate 26 (made of stainless steel 304). Among them, a very thin (about 10μm) special adhesive conductive coating layer is printed on the two planes of the piezoelectric ceramic 25. After the electrode plate 24 and the atomizing steel plate 26 are bonded and cured by pressure and heat, the three form an irreversible rigid connection. At the center of the atomizing steel plate 26, 200 dense array micropores with a diameter of only 3μm or 5μm are made in an area with a diameter area of ​​∅3 using laser micropore technology.

[0066] Combination Figure 12 As shown, the atomization principle of the ultrasonic atomizing plate assembly 14 is explained:

[0067] After the ultrasonic atomizing plate assembly 14 is fitted with a waterproof seal, it is installed in the preset slot of the spray outlet of the water tank of various atomizing products. The high-frequency (110KHz) current is conducted to the electrode plates 24 on the upper and lower sides of the piezoelectric ceramic plate 25 and the atomizing steel plate 26 through the positive and negative power supply leads. At this time, a high-frequency potential difference is formed between the atomizing steel plate 26 and the electrode plate 24. The high-frequency potential difference drives the piezoelectric ceramic plate 25 to generate high-frequency mechanical vibration. The piezoelectric ceramic plate 26 transmits the high-frequency mechanical vibration to the suspended and sealed atomizing steel plate 26. The matrix micropores of the atomizing steel plate 26 can ensure that the water in the water tank will not leak out when it is not working. However, under high-frequency vibration, these micropores will intermittently throw the medicine out, thereby completing the atomization of the medicine.

[0068] The working principle of this application is as follows: Figure 16 As shown, the atomizing plate assembly 14 of the device is installed above the mouth of the medicine bottle. A water-guiding cotton swab support 18 is added below the atomizing plate assembly 14, and the water-guiding cotton swab 16 is placed inside the water-guiding cotton swab support 18. One end of the water-guiding cotton swab 16 contacts the atomizing steel plate 26 of the atomizing plate assembly 14, and the other end is lifted by the clamping spring 17 to ensure that the other end of the water-guiding cotton swab 16 is always in close contact with the matrix micropores at the center of the atomizing steel plate 26. The water-guiding cotton swab support 18 has "1"-shaped liquid inlet holes on both sides. The medicine is transmitted to the atomizing steel plate 26 through the liquid inlet holes by the water-guiding cotton swab 16. When the atomizing steel plate 26 vibrates with ultrasound, the matrix micropores continuously and intermittently throw out the medicine. The medicine is atomized and enters the mouthpiece cavity. Under the action of human suction, the outside air enters through the air regulating ring 11 and the opening at the mouthpiece cavity and carries the medicine mist into the human body.

[0069] The air intake and air regulation principles of this device, such as its working principle. Figure 16 and the principle of regulating Qi Figure 13 As shown, since the amount of drug mist sprayed by the atomizing plate is very small and the spray height is low, the drug mist is not easily inhaled by the human body without the help of airflow. Therefore, the device is designed with an atomizing chamber structure on the upper cover 12 of the nozzle. "I"-shaped air inlets are opened on both sides of the atomizing chamber. At the same time, an airflow regulating ring 11 is added. The air inlet is located at the lower end of the spray to ensure that the drug mist is completely carried out by the airflow.

[0070] The air regulating ring 11 can rotate 360° within the annular groove of the nozzle cover 12. When the air inlet of the air regulating ring 11 is aligned with the air inlet opening of the nozzle cover, the air intake is at its maximum; conversely, it gradually decreases or can be completely closed.

[0071] The power supply and circuit control principles of this device are as follows: Figure 14 As shown:

[0072] The device is powered by a 3.7V lithium battery 5 and is designed with a charging PCB board 4. The charging interface is a Telephone-C interface 41. The charging PCB board 4 is designed with a charging indicator LED 42. The LED is always on when charging and turns off when charging is complete. The charging management IC 43 ensures charging safety and battery safety output, and maintains power supply safety.

[0073] The digital display tube 31 on the control PCB board 3 displays the number of drug administration cycles and the time interval between each working cycle. The P value is the number of working cycles, which is used to control the drug administration dose in each working cycle; the T value is the interval time value of the next working cycle, which is used to control the drug administration time interval.

[0074] Control button 34 corresponds to setting key 61 and serves as setting confirmation key and work output key; + button 35 and - button 36 correspond to adjustment key + 62 and adjustment key - 63 and serve as adjustment keys for modifying P value and T value;

[0075] The digital tube IC32 manages and drives the digital tube display function; the control IC33 completes the logic setting and work output functions; and the timing IC37 provides timing assurance for the drug administration interval.

[0076] The specific usage method of this device is as follows:

[0077] 1) Powering on / off: such as Figure 2 As shown, pressing the circular "Confirm" button five times consecutively while the device is off will illuminate the display screen, indicating that the device is powered on. In standby mode, pressing the circular "Confirm" button five times consecutively will turn off the display screen, indicating that the device is powered off. The device will automatically shut down if it remains in sleep / standby mode for more than 36 hours. After the device is powered off, the port number setting (P) and time setting (T) are automatically reset to factory settings and must be reset before the next use.

[0078] 2) Setting the number of ports P and time T: When the device is powered on, press the circular "Confirm" button twice to light up the letter "P" on the display screen; press the button twice more to turn off the letter "P" and light up the letter "T". When the letters P and T are lit up one after the other, you can adjust the value by pressing the "triangle" + / - keys. After each setting, you must press the circular confirm button again to complete the setting.

[0079] Note: When the number of ports P and time T are not set (i.e. both are displayed as 00), the control system defaults to an unconstrained continuous working state.

[0080] 3) Sleep and standby states: After the device completes the accumulation of each port count, the control system will immediately cut off the output, the display screen will turn off, and the system will enter a timed sleep state.

[0081] When the device is in sleep mode, pressing the circular confirmation button has no effect and there is no output; after the control system completes a setting timer in sleep mode, the letter T on the display screen is lit up. At this time, pressing and holding the circular confirmation button for 2 seconds will light up all the numbers on the display screen, and the device will enter standby mode.

[0082] 4) Operation and output conventions: When the device is in standby mode, pressing the circular confirmation button will immediately start spraying. Each output will last no more than 5 seconds. After 5 seconds, the button must be released and the circular confirmation button must be pressed again for normal output. Each time the button is released, the number of spray outlets decreases by one. When the number of spray outlets P is 0, one working cycle ends. The display screen will flash 3 times and then automatically turn off, and the device will enter the sleep timer state.

[0083] 5) Calculation methods for the number of ports P and the time T:

[0084] A. Device spray volume: V ml / 5 seconds B. Dosage per dose: W ml C. Number of doses per day: N times

[0085] D. P = W / VT = 12 / N.

[0086] as follows Figure 1 As shown, the device uses ultrasonic atomization technology. The ultrasonic device atomizes water-soluble drugs (liquid drugs), which patients can inhale through their mouth or nostrils, allowing the drugs to directly reach the lesion. This method of drug delivery directly to the lesion can improve the cure efficiency of drugs and provide a drug delivery route for the research and development and use of new and highly effective drugs.

[0087] The device is small in size and easy for patients to carry and use. Its length, width and height are 45*42*115mm, while existing similar devices are mostly medical equipment with a large size, which patients can only use in fixed places such as hospitals or homes.

[0088] like Figure 2 As shown, the device is specially designed with a mouthpiece and an air adjustment ring 11, which can realize the functions of oral and nasal inhalation of the nebulized drug mist. The air adjustment ring 11 can adjust the amount of air inhaled according to the individual needs of the patient.

[0089] like Figure 2 As shown, the device is specifically designed with dosing control and adjustment functions. Patients can adjust the number of doses (P) and the interval between doses (T) using the setting and adjustment buttons as directed by their doctor. Each time the patient inhales the medication, the P value on the dosing display decreases by one. When the P value reaches zero, the display turns off, and the device automatically shuts off its output. Simultaneously, the interval T is illuminated and displayed, decreasing by one unit every hour. When the T value reaches zero and remains constantly lit, the P value is illuminated and displays the number of doses inhaled, reminding the patient to wait for their next dose.

[0090] like Figure 15 As shown, the device adopts a split structure design, with the power supply and control components and the nebulizer inhalation components designed as two detachable structural components, thereby realizing the functions of drug addition and drug replacement.

[0091] This invention provides a convenient and efficient method for administering medications to patients with respiratory diseases such as lung disease, bronchial disease, pharyngeal disease, rhinitis, and upper respiratory tract disease. Furthermore, this invention offers new technical support and market prospects for drug development and social needs in other medical fields and consumer applications.
