Description
Technical Field
The invention belongs to the field of medical atomization, and particularly relates to an electrostatic atomization drug delivery system for breaking liquid drops into micro-liquid drops based on a multi-micro-pore array.
Background
Along with the development of productivity and the improvement of medical level, the aerosol inhalation therapy is a special crowd such as the old and young, avoids intravenous injection pain, becomes the first choice therapy of respiratory diseases, and is also the most main means of bronchopurification treatment. The method uses an atomization device to disperse the medicine (solution or powder) into tiny fog drops or particles, so that the tiny fog drops or particles are suspended in the gas and enter the respiratory tract and the lung, thereby achieving the purpose of local or systemic treatment.
The types and forms of current therapeutic nebulizers are numerous, and the purposes of the different nebulizers are determined by the respective design operating characteristics. Mechanical atomizers form the mist by different mechanical means. Such as an ultrasonic atomizer, which vibrates a liquid into microscopic droplets with energy generated by ultrasonic vibration. However, because of large atomized particles, most inhaled medicine particles can only be deposited on the upper respiratory tract such as the oral cavity, the throat and the like, can not effectively treat the lower respiratory tract diseases, and can easily cause the liquid medicine to form water drops to be hung on the inner cavity wall, so that the liquid medicine has high demand and causes the phenomenon of waste; meanwhile, the atomizer has the advantages of quick atomization, easy hypoxia, choking and the like, so that the use of the atomizer in hospitals is basically stopped. Most pneumatic atomizers have the principle of suction effect (bernoulli effect) as the basic working principle, and when high-speed air flow passes through a tiny opening of a liquid suction pipe, a negative pressure effect is generated around the high-speed air flow, and liquid required for treatment is sucked into the air flow and impacted into tiny liquid drops suspended in the air flow, so that aerosol is formed. Compared with an ultrasonic atomizer, the ultrasonic atomizer has proper atomization amount inhaled in the same treatment time, and is not easy to cause hypoxia and choking. Atomized particles are finer, can go deep into treatment of the lower respiratory tract, are not easy to collide and combine, reduce waste of liquid medicine, and the atomizer used in hospitals at present is basically the same type. However, as the demand for atomization increases, the disadvantages of air-compressed atomizers are also becoming more and more pronounced. The volume is large, the noise is large, the fear psychology is easy to generate for infants, and the atomization is resisted; the portable electric power box is not easy to carry, requires an external power supply in work, and can be used in hospitals or at home only; the stability of the medicine is affected, the air flow is impacted, and the temperature is easy to be increased, so that the stability of the medicine is affected.
Micro-grid atomizers belong to the new generation of atomizers. The spraying mode is to spray by utilizing tiny ultrasonic vibration and a net type spray head structure, and the liquid water molecular structure is scattered to generate natural and elegant superfine water mist through high-frequency resonance of the ceramic atomizing sheet, so that the efficient spraying effect is realized, the size is small, the noise is low, and the carrying and the use are convenient at any time and any place. However, this technique has a fatal disadvantage in that the micro-screen has thousands of small holes with a diameter of 3 μm, which are easily clogged after multiple use and washing, resulting in a decrease in the amount of mist or even no mist, and the durability of the mist screen is the greatest.

It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
As shown in fig. 1, a medical atomization device based on multi-micro-hole array electrostatic atomization comprises a gas-liquid mixing cavity 13, wherein a dust filtering net 10 and a downward-arranged miniature axial flow fan 4 are arranged at the top opening of the gas-liquid mixing cavity 13; the dust filter screen 10 is detachable and replaceable, the dust filter screen 10 filters air flowing into the air-liquid mixing cavity 13 from the outside, so that the PM2.5 content is reduced, cleaner air is obtained when people inhale, the liquid medicine is prevented from being polluted, and the probability of cross infection is reduced.
A liquid storage tank 5 is axially arranged in the gas-liquid mixing cavity 13, and the liquid storage tank 5 is used for storing liquid medicine; the bottom of the gas-liquid mixing cavity 13 is connected with the suction mask 14 through a gas-liquid conveying pipe 15. The liquid storage tank 5 is fixed with the inner wall of the gas-liquid mixing cavity 13 by the support 6, in this embodiment, the support 6 is made of insulating material, such as nylon, and the insulating support 6 insulates the charged liquid medicine in the liquid storage tank 5 from the gas-liquid mixing cavity 13.
The top of the liquid storage tank 5 is connected with the outlet of the micro booster pump 2 through a gas pipeline, the inlet and the outlet of the micro booster pump 2 are respectively provided with a gas flow valve 1, the power line of the micro booster pump 2 is connected with a voltage controller 3, and the pressure inside the liquid storage tank 5 can be regulated through the voltage controller 3 and the gas flow valve 1, so that proper atomization flow is obtained. As shown in fig. 2, a capillary array is arranged at the bottom of the liquid storage tank 5, and the capillary array is formed by a plurality of capillaries 7 perpendicular to the bottom surface of the liquid storage tank 5; and a conductive coating 11 such as tin oxide and indium oxide is sprayed on the outer side of the bottom surface of the liquid storage tank 5; the conductive coating 11 is connected with the negative high voltage of the high voltage electrostatic generator 12 through a wire, so that all capillaries 7 are provided with the negative high voltage; an adjusting plate 8 is arranged at the position, which is opposite to the outlet of the capillary tube 7, of 500 micrometers, a ground polar plate 9 is arranged at the position, which is opposite to the position, which is 2 centimeters away from the position, which is opposite to the position, of the adjusting plate 8, holes which are in one-to-one correspondence with the capillary tube 7 are formed in the adjusting plate 8 and the ground polar plate 9, the adjusting plate 8 is connected with a negative high-voltage static electricity generating device, and the ground polar plate 9 is grounded; because each capillary tube 7 and the adjusting plate 8 have negative high pressure and have potential difference, atomized submicron liquid drops are not easy to drop due to entrainment to the end face of the liquid storage tank 5, and meanwhile, the voltage edge effect between adjacent capillary tubes 7 can be eliminated, so that the atomization stability of each capillary tube 7 is ensured. Further, a high-voltage electric field is formed between the adjusting plate 8 and the earth electrode plate 9, so that charged liquid drops are broken under the action of coulomb repulsion force; in this embodiment, the adjusting plate 8 and the ground plate 9 may be made of copper plates, the capillary tube 7 is made of stainless steel, and the diameters of the capillary tube 7 are 300-400 micrometers.

Since the conductive coating 11 at the bottom of the liquid storage tank 5 is connected to the negative high pressure, all capillaries and liquid medicine are brought to the negative high pressure.
The liquid medicine extruded from the end face of the capillary array is charged and then crushed into submicron-sized fog drop groups under the action of a high-voltage electric field between the adjusting plate 8 and the ground electrode plate 9, and the submicron-sized liquid medicine fog drop groups enter the respiratory tract and the lung from the suction mask 14 by a person through the gas-liquid conveying pipe 15 under the self weight and the pushing of the miniature axial flow fan 4. Meanwhile, the airflow generated by the miniature axial flow fan 4 conveys the submicron-sized fog drops to the respiratory tract of a human body, and meanwhile, backflow of fog drops is avoided, so that the nylon bracket 6 is always kept in a dry and insulating state.
In summary, compared with the micro-grid atomizer in the prior art, the micro-grid of the micro-grid atomizer consists of thousands of small holes with the diameter of 3 microns, the micro-grid atomizer is easy to block after being used and cleaned for multiple times, so that the mist output is reduced or even not output, and the problem is well avoided by adopting the multi-micro-hole array electrostatic atomization in the invention, and the atomizing flow requirement of the medical atomizer with the same level can be easily realized. In addition, compared with commonly used type atomizers such as SVN on the market, the atomizer utilizing the electrostatic atomization principle can have quite low cost and excellent silencing effect, and the electrostatic atomization has quite general applicability for different dosing liquids, so that the reliability can be well ensured.
