Description

Technical Field

[0001] The present invention belongs to the technical field of medical equipment, and in particular relates to a medical atomizer powered by a flexible organic solar cell and a method of using the same. Background Art

[0002] Nebulized inhalation therapy has long been one of the best options for direct drug delivery to patients with respiratory diseases. The medication is dispersed into small droplets through specialized atomization equipment and inhaled by the patient, delivering the drug directly to the affected respiratory tract. Currently, there are three main types of nebulizers used clinically: ultrasonic nebulizers, jet nebulizers, and medical nebulizers. Medical nebulizers, which require no electrical power and are compact and portable, are the primary choice for home medication nebulizers.

[0003] Currently, the most popular medical nebulizers on the market are small ultrasonic nebulizers that use a lithium battery as the energy storage unit and a mesh atomizer as the atomization unit. However, lithium battery-based medical nebulizers require regular charging from an external power source to maintain their use. This can be inconvenient for patients during daily use. In some special circumstances, such as when patients neglect to charge, use the nebulizer for extended periods outdoors, or encounter long-term power outages caused by natural disasters, the battery can run out of power, rendering the nebulizer inoperable and potentially endangering the patient's health and safety. Mainstream medical nebulizer manufacturers often address this energy supply issue by adding additional lithium battery packs. However, oversized lithium battery packs compress the drug storage space and make the nebulizer bulky, making it difficult to carry around. Furthermore, the changing environment in which patients use the nebulizer can also affect the lithium battery. For example, when the ambient temperature drops below 0°C, the electrolyte viscosity within the battery increases or even partially solidifies, slowing the diffusion of charged particles and reducing the battery's output power. This poses a serious safety hazard for patients in emergency situations.

[0004] Furthermore, since medical nebulizers are primarily used by elderly individuals with limited respiratory capacity and young children, they are often subject to drops and bumps during use. Thermal runaway of lithium batteries due to mechanical damage is one of the most common causes of lithium battery fires. While current industrial designs can largely mitigate fires caused by thermal runaway due to mechanical damage, small lithium battery combustion or explosion accidents still occur due to the complex and changing user environments and the presence of defective products.

[0005] Sustainable energy recharge is an effective solution to the battery life issues of small appliances. However, there are currently no solar-powered mesh-type drug atomizers on the market. This may be due to a mismatch between solar energy and lithium-ion battery packs, commonly used energy storage devices. The voltage of a single solar cell under standard sunlight is typically around 1V. To meet the charging voltage of a lithium-ion battery pack, multiple solar cells are typically connected in series to meet this charging requirement. Furthermore, the voltage of solar energy generation is significantly dependent on the ambient light environment. Under warmer light conditions, such as sunset, the voltage of the solar cell generation is lower, while under stronger light conditions, such as midday summer, the voltage is higher. For a solar cell pack constructed with multiple solar cells in series, varying light conditions can cause significant fluctuations in the voltage of the cells. If the voltage of the solar cell generation is too low, the lithium-ion battery pack cannot be charged. If the voltage of the solar cell generation is too high, the lithium-ion battery pack will overcharge, leading to irreversible internal polarization and even lithium deposition, posing a safety hazard. Using an external module to control the charging voltage and current would further increase the device size and significantly reduce charging efficiency.

[0006] In short, there is currently a lack of a self-powered, safe and reliable medical nebulizer on the market. Summary of the Invention

[0007] In response to the above problems, the purpose of the present invention is to provide a medical nebulizer powered by flexible organic solar cells and a method of use thereof, so as to solve the problem of the current lack of self-powered, safe and reliable medical nebulizers on the market.

[0008] To achieve the above object, the present invention adopts the following technical solutions: In a first aspect, the present invention discloses a medical nebulizer powered by a flexible organic solar cell, comprising an atomization generating device, wherein the atomization generating device comprises a grid atomization sheet and a drug storage chamber, wherein the drug storage chamber stores drugs and is connected to the grid atomization sheet.

[0013] Preferably, it also includes a breathing mask and a mask connecting tube, and the breathing mask is connected to the atomization generating device through the mask connecting tube.

[0014] Preferably, the flexible organic solar cell group uses a silver electrode as a cathode and a transparent electrode as an anode, and is composed of a flexible substrate, a transparent electrode, a hole transport layer, an organic photoactive layer, an electron transport layer and a silver electrode stacked in sequence from bottom to top.

[0015] In a second aspect, the present invention further discloses a method for using the above-mentioned medical nebulizer powered by a flexible organic solar cell, comprising: Step S1: The medicine stored in the medicine storage chamber reaches the mesh atomization sheet through capillary action; Step S2: The flexible organic solar cell group supplies power to the atomizer drive circuit board through the energy storage capacitor. The atomizer drive circuit board provides a high-frequency oscillating current to the grid atomizer, prompting the medicine on the grid atomizer to be sprayed out to form an aerosol.

[0016] Wherein, the step S2 includes the following steps: Step S21: the flexible organic solar cell group continuously charges the energy storage capacitor under light conditions to convert light energy into electrostatic potential energy, and the energy storage capacitor then supplies the electrostatic potential energy to the atomizer drive circuit board; Step S22: the atomizer driving circuit board converts the DC output of the energy storage capacitor into a high-frequency oscillating current; Step S23: The high-frequency oscillating current continuously acts on the mesh atomizer to drive the medicine on the mesh atomizer to be sprayed out to form an aerosol.

[0017] When the voltage of the energy storage capacitor is insufficient to charge the atomizer drive circuit board, the atomizer drive circuit board can be connected to a common charging port for charging to meet emergency charging needs.

[0018] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention discloses a medical nebulizer powered by a flexible organic solar cell, comprising an atomization generating device, the atomization generating device comprising a grid atomizing plate, a drug storage chamber, an energy storage capacitor and a flexible organic solar cell group, wherein the drug storage chamber stores drugs and is connected to the grid atomizing plate; the grid atomizing plate is provided with an atomizing plate driving circuit board, the energy storage capacitor is connected to the atomizing plate driving circuit board; the flexible organic solar cell group is connected to the energy storage capacitor.

[0019] (II) The present invention discloses a medical nebulizer powered by a flexible organic solar cell. It has a simple structure, is lightweight and easy to carry, and can be continuously charged in most usage scenarios, making it convenient for patients to use daily. Specifically, the advantages are: 1. The present invention uses capacitors instead of lithium batteries as energy storage units. Compared with lithium batteries, capacitors have a longer service life, and physical rather than chemical energy storage makes them safer and more adaptable to the environment. They can operate normally between -55°C and 110°C and ensure stable energy storage. They are more stable and less likely to cause accidents such as combustion or explosion, making them safer.

[0020] 2. The present invention uses flexible organic solar cells as charging units. Compared with flexible perovskite solar cells, the possibility of accidental ingestion of medical nebulizers is higher than that of the general population because the users of medical nebulizers are mostly preschool children and elderly patients with reduced behavioral abilities. Currently, most mainstream perovskite solar cells contain heavy metal ions such as lead, which have a great impact on health if ingested. Organic solar cells are prepared from conjugated polymers and organic macromolecules, are non-toxic and harmless, do not contain heavy metals, and can be used in scenarios where they come into direct contact with the human body.

[0021] 3. The present invention uses a flexible organic solar cell group as a charging unit, which is not only flexible but also lightweight. The overall thickness of the device can be adjusted to no more than 1 mm according to the process to fit the housing of devices with different shapes, and the application scenarios are flexible.

[0022] 4. Compared with the mainstream polycrystalline silicon solar cells in the market, flexible organic solar cell groups have higher photoelectric conversion efficiency in most light source environments, such as natural strong light and indoor low light environments. In addition, the overall device is lighter and thinner than polycrystalline silicon solar cells, which is suitable for most usage scenarios of medical drug nebulizers.

[0023] 5. Because capacitors store energy through electrostatic potential, they can be charged simply by providing a charging voltage greater than the internal reverse voltage. They are highly tolerant to unstable charging power supplies and have high energy conversion efficiency. Compared to lithium batteries, capacitor charging is more suitable for solar cells. However, capacitors have lower energy density than lithium batteries and require continuous charging to ensure a maximum number of uses. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In order to protect the internal electrical components of the atomizer drive circuit board a, the area where the atomizer drive circuit board a is located should be sealed relative to other units.

[0052] Example 2: A method for using a medical nebulizer powered by a flexible organic solar cell Example 2 provides a method for using a medical nebulizer powered by a flexible organic solar cell. The method uses the medical nebulizer powered by a flexible organic solar cell according to Example 1, and includes the following steps: Step S1: The medicine stored in the medicine storage chamber B reaches the mesh atomization sheet A through capillary action; Step S2: The flexible organic solar cell group D supplies power to the atomizer drive circuit board a via the energy storage capacitor C. The atomizer drive circuit board a provides a high-frequency oscillating current to the grid atomizer sheet A, thereby causing the drug on the grid atomizer sheet A to be ejected outward to form an aerosol, comprising the following steps: Step S21: The flexible organic solar cell group D continuously charges the energy storage capacitor C under light conditions to convert light energy into electrostatic potential energy.

[0056] Feasibility analysis: When acute respiratory diseases such as asthma occur, the nebulizer needs to work for at most two deep breathing treatments, each working for 10 to 15 seconds, consuming at most 0.0125Wh of energy. The maximum energy loss over two treatments is about 0.025Wh. A single charge can provide energy for 20 to 30 treatments.

[0057] We use a solar cell array under sunlight at 1.5 standard atmospheres to charge the capacitor. Since the device is installed on a cylindrical device with a radius of 3 cm, we measured that the output power of the solar cell under this condition is 189 mW. Since the solar cell has a very high efficiency in charging the capacitor, we have measured that the energy loss is usually no more than 10%. Therefore, under outdoor sunlight conditions, one course of treatment can be completed every 5 minutes, which meets the needs of most patients. Under indoor lighting conditions, we use the international indoor photovoltaic lighting standard of 167 μW / cm 2 Using light source as the test condition, the indoor photoelectric conversion efficiency of the large-area flexible organic solar cell is 14.7%. 20 hours of indoor lighting can complete one course of charging. Acute respiratory diseases such as asthma generally occur less than once a week, and extreme conditions can also meet the usage requirements. Therefore, the device meets the definition of composite self-powered.
