Description

Technical Field

[0001] The invention relates to medical equipment and civilian consumer electronic products, and in particular to a portable ultrasonic liquid medicine atomizing inhalation device. Background Art

[0002] The principle of ultrasonic atomization is to use ultrasonic vibration to generate pressure waves through liquid, thereby breaking up the liquid into tiny droplets. The ultrasonic transducer in the ultrasonic atomizer converts electrical energy into high-frequency mechanical vibrations. When the surface of the liquid is affected by ultrasonic vibrations, periodic pressure changes will occur. The local negative pressure area will cause tiny bubbles to form inside the liquid. These bubbles continue to expand and contract. When the bubbles expand to a certain extent, they will burst due to the excessive internal and external pressure difference. The instantaneous high-pressure wave generated by the rupture will eject the liquid from the bubble, forming a large number of tiny droplets. During the rupture process, the liquid is cut into very fine water mist. Due to this effect, ultrasonic atomization is often used for air humidification, drug atomization, etc.

[0003] Compared with the main drug administration methods for patients with traditional respiratory diseases and other diseases (injectable drugs: intramuscular injection or intravenous infusion through a bottle, the drugs reach the lesions indirectly; tablets, pills, and Chinese herbal decoctions: oral administration into the digestive system, the drugs reach the lesions indirectly), the atomized drug solution can make the drugs act directly on the lesions and improve the treatment effect.

[0004] Existing methods of drug liquid atomization: (1) are carried out in hospitals or other treatment institutions. The inconvenience is that patients are restricted to designated places (such as hospitals) to inhale drug liquid atomization, which has limitations in use; (2) There are also some simple atomization devices on the market, but they are inconvenient to use: most of them have an integrated structure, which is inconvenient to change the medicine, the inhalation method of the atomized drug liquid is single, and it is impossible to adjust the air intake and drug dosage.

Correspondingly, an opening is provided at the bottom of the battery housing 1 for connecting with the tepy-C interface 41 to realize charging, and a label 10 is provided on the outside of the bottom side wall of the battery housing 1 for warning purposes;

[0052] A control PCB board 3 is provided in the battery housing 1 in front of the battery holder 2, a lithium battery 5 is provided between the control PCB board 3 and the battery holder 2, a panel 9 is embedded in the front side of the battery housing 1, a button 6 is installed on the panel 9, the button 6 is used to adjust the device, and a digital display tube 31 for display is also provided above the button 6;

[0053] Two spring electrodes 8 are provided at the middle of the top of the battery holder 2 and are distributed on the left and right sides. In addition, two magnets 7 are provided on the front and rear sides of the spring electrode 8. The spring electrode 8 and the magnet 7 are embedded in the slot of the battery holder 2 by interference fit.

[0054] When assembling the battery assembly 200, first press the two metal standard component spring electrodes 8 into the two cylindrical slots in the middle of the battery holder 2, then stick the lithium battery 5 to the back of the control PCB board 33 with a double-sided sponge adhesive, and then insert the lithium battery 5 and the control PCB board 3 into the rectangular blind hole groove on the lower end surface of the battery holder 2, and at the same time, insert the charging PCB board 4 into the bottom of the cylindrical tube of the battery holder 2 and constrain and fix the other end of the control PCB board 3, and then tighten the charging PCB board 4 with screws to connect the spring electrodes 8 and the charging PCB board 4 with the control PCB board 3 through soldering;

[0055] Install the battery holder 2 into the battery housing 1, and use four self-tapping screws to lock the battery holder 2 at the open end of the battery housing 1. The button 6 is made of engineering plastic. The button 6 is placed in the corresponding special-shaped groove on the side of the battery housing 1. The panel 9 is inserted 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 a high-viscosity 3M double-sided tape on the back;

[0056] Press four magnets 7 into four corresponding cylindrical slots on the outer end surface of the battery holder 2 respectively. The label 10 is made of transparent PVC material, screen-printed and single-sided adhesive. The label 10 is pasted on the bottom of the battery housing 1;

[0057] The four disc-shaped rare earth material magnets 7 and the metal material spring electrodes 8 of the battery assembly 200 are respectively embedded in the corresponding structural slots of the plastic battery holder 2 in an interference fit manner, and the two spring electrodes 8 are respectively connected to the control PCB board 3 located under the battery holder 2 by wires to form a battery holder 2 assembly. After the battery holder 2 assembly is installed in the plastic battery housing 1, a trapezoidal groove is formed;

[0058] like Figure 4 , Figure 8 and Fig. 9 As shown, the atomization assembly 100 is composed of a nozzle upper cover 12, an air regulating ring 11, a medication bottle 23 and a nozzle lower cover 19, a water-conducting cotton swab 16, a water-conducting cotton swab bracket 17, a tightening spring 18, a single electrode 20, a magnetic magnet 21, and an atomization sheet assembly 14;

[0059] The nozzle upper cover 12 is fixed to the nozzle lower cover 19 by screws, and the nozzle lower cover 19 is connected to the medication bottle 23 by threads. The threaded installation makes it easy to disassemble the medication bottle 23 from the nozzle lower cover 19, and then to replace or add liquid medicine. The medication bottle 23 is made of medical glass, and its bottle mouth thread is screwed and connected to the nozzle lower cover 19. The nozzle upper cover 12 and the nozzle lower cover 19 are made of food-grade engineering plastics. A medicine bottle sealing gasket 22 is designed between the nozzle lower cover 19 and the bottle mouth of the medication bottle 23 to improve the sealing effect. The medicine bottle sealing gasket 22 is made of food-grade silicone.

[0060] The lower end of the nozzle of the nozzle upper cover 12 is designed with a circle of annular grooves, and two symmetrical "I"-shaped air inlet holes are opened on the side of the annular groove. The air regulating ring 11 is sleeved on the annular groove on the nozzle upper cover 12. The air regulating ring 11 is made of silicone. In an elastic state, the air regulating ring 11 is inserted into the annular groove of the nozzle upper cover 12 from one side of the nozzle. The side of the air regulating ring 11 is also designed with symmetrical "I"-shaped hollow grooves. The air regulating ring 11 can be rotated to adjust the air intake when inhaling the medicine mist.

[0061] The water-conducting cotton swab 16 is made of chemical fiber and is placed in the water-conducting cotton swab bracket 18. The water-conducting cotton swab bracket 18 is made of food-grade engineering plastic. A compression spring 17 is designed at the bottom of the water-conducting cotton swab bracket 18. The spring 17 presses the water-conducting cotton swab 16 upward to ensure that the water-conducting cotton swab 16 is always tightly fitted with the atomizing sheet assembly 14. The two sides of the water-conducting cotton swab bracket 18 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 sheet assembly 14. The water-conducting cotton swab bracket 18 is installed at the center of the upper cover 12 and the lower cover 19 of the suction nozzle, and is clamped and fixed by the two, and the atomizing sheet assembly 14 is located directly above the water-conducting cotton swab bracket 18;

[0062] The atomizer assembly 14 is a piezoelectric ceramic assembly, which is placed in the annular shallow groove raised by the lower cover 19 of the nozzle. The upper side of the atomizer assembly 14 is designed with an atomizer seal gasket 13 and the lower side is designed with an atomizer seal gasket 15. The upper and lower seal gaskets ensure the elasticity of the atomizer assembly 14 during ultrasonic vibration on the one hand, and ensure that the medicine and medicine mist residue do not enter the inside of the atomizer assembly 100 on the other hand, so as to avoid power supply short circuit. The materials of the atomizer seal gasket 13 and the atomizer seal gasket 15 are both food-grade silicone materials;

[0063] After the plastic nozzle upper cover 12 is combined with the nozzle lower cover 19, the atomizer assembly 100 forms a trapezoidal boss. Below the trapezoidal boss, the magnet 21 and the single electrode 20 are respectively provided at the positions corresponding to the magnet 7 and the spring electrode 8. When the four magnets 7 of the battery assembly 200 are respectively attracted to the four magnets 21 of the atomizer assembly 100, the trapezoidal boss of the atomizer assembly 100 and the trapezoidal groove of the battery assembly 200 are gap-matched, and the atomizer assembly 100 is constrained and fixed in the groove of the battery assembly 200.

[0064] The four iron cylindrical embossed magnets 21 and two iron single electrodes 20 of the same specification of the atomizer assembly 100 are also fitted into the corresponding structural slots on the outer end surface of the plastic nozzle lower cover 19 in an interference fit manner. At the same time, the two spring electrodes 8 in the battery assembly 200 are respectively compressed and contacted by the two single electrodes 20 on the atomizer assembly 100 to form power supply conduction.

[0065] The two single electrodes 20 and the four magnets 21 are all made of carbon steel. After embossing and electroplating, they are embedded in the corresponding slots of the lower cover 19 of the nozzle by an interference fit process. The two single electrodes 20 are respectively connected to the positive and negative electrodes of the atomizer assembly 14 by soldering with wires.

[0066] like Fig.10 and Fig.11 As shown, the atomizing sheet assembly 14 is composed of an electrode sheet 24 (stainless steel 304 material), a piezoelectric ceramic 25 (piezoelectric ceramic material), and an atomizing steel sheet 26 (stainless steel 304 material). Among them, two planes of the piezoelectric ceramic 25 are respectively printed with a very thin (about 10 μm) layer of special adhesive conductive coating. After pressurization, heating, bonding and curing, the electrode sheet 24 and the atomizing steel sheet 26 form an irreversible rigid connection. The center of the atomizing steel sheet 26 is formed by a laser micro-hole process in the diameter area. 200 dense array micropores with a diameter of only 3μm or 5μm were produced within a range of 1.5mm.

[0067] Combination Fig.12 As shown, the atomization principle of the ultrasonic atomization sheet assembly 14 is described:

[0068] The ultrasonic atomizer assembly 14 is covered with a waterproof seal and installed in a preset slot at the spray outlet of a water tank of various atomization products; a high-frequency (110KHz) current is transmitted to the electrode sheets 24 and the atomizing steel sheet 26 on the upper and lower surfaces of the piezoelectric ceramic sheet 25 through the positive and negative power supply leads. At this time, a high-frequency potential difference is formed between the atomizing steel sheet 26 and the electrode sheet 24. The high-frequency potential difference drives the piezoelectric ceramic sheet 25 to generate high-frequency mechanical vibrations, and the piezoelectric ceramic sheet 26 transmits the high-frequency mechanical vibrations to the suspended closed atomizing steel sheet 26; the matrix micropores of the atomizing steel sheet 26 can ensure that the water in the water tank will not leak out in the non-working state, but under the high-frequency vibration, these micropores will continuously and intermittently throw the medicine out, thereby completing the atomization of the medicine.

[0069] The working principle of this application is as follows: Fig.16 As shown, the atomizing sheet assembly 14 of the device is installed on the upper side of the mouth of the medicine bottle, and a water-conducting cotton swab bracket 18 is additionally designed at the lower side of the atomizing sheet assembly 14, and the water-conducting cotton swab 16 is placed in the water-conducting cotton swab bracket 18; one end of the water-conducting cotton swab 16 is in contact with the atomizing steel sheet 26 of the atomizing sheet assembly 14, and the other end is lifted by the tightening spring 17 to ensure that the other end of the water-conducting cotton swab 16 is always in close contact with the matrix micropores at the center of the atomizing steel sheet 26; "1"-shaped liquid inlet holes are opened on both sides of the water-conducting cotton swab bracket 18, and the medicine is transmitted to the atomizing steel sheet 26 by the water-conducting cotton swab 16 through the liquid inlet holes. When the atomizing steel sheet 26 vibrates ultrasonically, the matrix micropores throw out the medicine continuously and intermittently, and the medicine is atomized into the suction nozzle cavity. Under the action of artificial suction, the outside air enters through the openings at the air regulating ring 11 and the suction nozzle cavity and enters the human body with the medicine mist.

[0070] The air intake and air conditioning principle of the device, such as the working principle Fig.16 And the principle of gas regulation Fig.13 As shown, since the amount of medicine mist sprayed by the atomizer is very small and the spray height is low, the medicine mist is not easy to be inhaled by the human body without the drive of airflow. Therefore, the device is designed with an atomization chamber structure on the upper cover 12 of the suction nozzle, and "I"-shaped air inlets are opened on both sides of the atomization chamber. At the same time, an air inlet flow adjustment ring 11 is added, and the air inlet hole is located at the lower end of the spray, which can ensure that the medicine mist is completely taken out by the airflow;

[0071] The air regulating ring 11 can rotate 360 ​​degrees in the annular groove of the nozzle cover 12. When the air inlet hole of the air regulating ring 11 is directly opposite to the air inlet opening of the nozzle cover, the air intake is the largest. Otherwise, it gradually shrinks and can be completely closed.

[0072] The power supply and circuit control principle of the device, such as Fig.14 As shown:

[0073] The power source of the device is a 3.7V lithium battery 5, and a charging PCB board 4 is designed. The charging interface is a tepy-C interface 41. A charging display LED light 42 is designed on the charging PCB board 4. The LED light is always on during charging, and the LED light goes out when charging is completed; the charging management IC 43 ensures charging safety and battery safety output, and maintains power supply safety;

[0074] The digital display tube 31 of the control PCB board 3 displays the number of drug administrations in each working cycle and the time interval of each working cycle. The P value is the working number, 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;

[0075] The control button 34 corresponds to the setting key 61, which is a setting confirmation key and a work output key; the + button 35 and the - button 36 correspond to the adjustment key +62 and the adjustment key -63, which are the modification adjustment keys for the P value and the T value;

[0076] The digital tube IC32 manages and drives the digital tube display function; the control IC33 completes the logic setting and work output function; the timing IC37 provides timing guarantee for the drug administration time interval.

[0077] The specific usage of the device is as follows:

[0078] 1) Switch on and off: Figure 2 As shown, in the shutdown state, press the circular "confirmation button" 5 times in a row, the display screen will light up, and the device will turn on; in the standby state, press the circular "confirmation button" 5 times in a row, the display screen will go out, and the device will turn off. The device will automatically shut down if it is in sleep standby for more than 36 hours. After the device is shut down, the number of mouths setting P and time setting T are automatically cleared and restored to the factory state. They must be reset before the next startup.

[0079] 2) Setting of number of mouths P and time T: When the machine is powered on, press the circular “confirm button” twice in succession, and the letter “P” on the display will light up; press the button twice more in succession, and the letter “P” will go out and the letter “T” will light up. When the letters P and T are lit up successively, you can press the “triangle” + / - button to adjust the value. After each setting is completed, you must press the circular confirmation button again to complete the setting.

[0080] Note: When the number of mouths P and time T are not set (i.e. both display 00), the control system defaults to unconstrained continuous working state.

[0081] 3) Sleep and standby state: After the device completes a number of accumulated mouths, the control system will immediately cut off the output, the display screen will go out, and the system will enter the timed sleep state.

[0082] When the device is in sleep mode, pressing the circular confirmation button will have no effect and no output; after the control system completes a set timing in sleep mode, the letter T on the display screen is lit. At this time, press and hold the circular confirmation button for 2 seconds, all the numbers on the display screen are lit, and the device enters standby mode.

[0083] 4) Working and output agreement: When the device is in standby mode, press the circular confirmation button and the device will spray immediately. Each output shall not exceed 5 seconds. After 5 seconds, you must release the button and press the circular confirmation button again for normal output. Each time the button is released, the number of mouths decreases once. When the mouth count P value is 0, a working cycle ends, the display screen flashes 3 times and then automatically turns off, and the device enters the sleep timing state.

[0084] 5) Calculation method of number of mouths P value and time T value:

[0085] A. Spray volume of the device: V ml / 5 seconds B. Dosage per administration: W ml C. Number of administrations per day: N times

[0086] DP=W / VT=12 / N.

[0087] as follows Figure 1 As shown, the device adopts ultrasonic atomization technology. After the ultrasonic device atomizes the water-soluble medicine (liquid medicine), the patient can inhale the medicine mist into the body through the mouth or nostrils, so that the medicine can reach the lesion directly. This method of delivering the medicine directly to the lesion can improve the healing efficiency of the medicine on the one hand, and provide a drug delivery route for the development and use of new and efficient medicines on the other hand.

[0088] The device is small in size and convenient for patients to carry and use; the length, width and height of the device are 45*42*115mm respectively, while existing devices of the same type are mostly medical equipment structures with large size, and patients can only use them in fixed places such as hospitals or homes.

[0089] like Figure 2 As shown, the device is specially designed with a nozzle and an air regulating ring 11, which can realize the oral and nasal inhalation functions of the atomized medicine mist. The air regulating ring 11 can adjust the amount of air inhalation according to the patient's personal needs.

[0090] like Figure 2 As shown in the figure, the device is specifically designed with drug administration control and adjustment functions. Patients can follow the doctor's instructions to adjust the number of times each drug is administered (P) and the interval time (T) for the next drug administration through the work setting button and the drug administration adjustment button. The value of P on the drug administration display will decrease once each time the patient inhales the drug. When the P value is zero, the P display will go out and the device will automatically shut down the output; at the same time, the next drug administration time interval T will be lit and the interval time value will be displayed. The T value will decrease by one digital unit every hour.
