Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a drug atomization device and method. Background Technology

[0002] Nebulizers are commonly used medical devices in the treatment and home care of respiratory diseases. They deliver liquid medications into the patient's respiratory tract by atomizing them, offering the advantages of direct drug delivery and rapid onset of action, and have a wide range of applications. Currently, nebulizers are often purely mechanical devices. These devices mainly rely on a spring and a helical transmission mechanism to provide the nebulization power. Before use, the user needs to manually pre-compress the spring, and then use the elastic potential energy of the spring's rapid release to drive the delivery of the liquid medication and complete the atomization.

[0003] However, this structure has obvious drawbacks: the spring pre-compression process requires the user to apply considerable hand force, which is difficult to operate and results in a poor user experience for the elderly, those with weak hand strength, or those with mobility issues. Furthermore, the amount of manual force applied is difficult to standardize, easily leading to unstable nebulizer output pressure and single-dose dosage, insufficient nebulization accuracy, and consequently affecting clinical treatment outcomes. Summary of the Invention

[0004] The purpose of this invention is to provide a drug nebulization device and method, which solves the problems existing in the prior art, realizes lightweight and convenient operation of nebulization, is suitable for users with weak hand strength, and achieves precise and stable control of drug inhalation volume and nebulization output pressure, greatly improving the quantitative accuracy and applicability of drug nebulization administration.

[0005] To achieve the above objectives, the present invention provides the following solution: a drug atomizing device, comprising a housing, wherein an installation chamber and a drug receiving area are formed in the housing; A reciprocating motor is installed in the mounting chamber. The reciprocating motor has an output shaft that reciprocates in a linear direction. A transmission connector is connected to the output shaft end of the reciprocating motor. A negative pressure generator is also fixedly installed in the installation chamber. The negative pressure generator includes a cylinder and a piston. The piston is connected to the end of the transmission connector away from the reciprocating motor. The cylinder is provided with a suction pipe and a discharge pipe; both the suction pipe and the discharge pipe have a connecting end and a free end, and the connecting end of the suction pipe and the connecting end of the discharge pipe are connected to the cylinder; the suction pipe is provided with a one-way valve, which only allows fluid to flow from the free end of the suction pipe to its connecting end; The free end of the suction tube extends into the drug-containing area; the free end of the outlet tube is connected to the inlet of the atomizer.

[0006] In one embodiment, the transmission connector is a connecting plate. The output shaft axis of the reciprocating motor is parallel to the axis of the piston component. The connecting plate is arranged perpendicular to the output shaft axis. One end of the connecting plate is fixedly connected to the end of the output shaft of the reciprocating motor, and the other end of the connecting plate is fixedly connected to the end of the piston component.

[0007] As one embodiment, a medicine bottle fixing device is installed in the medicine containing area, and the free end of the suction tube is positioned toward the clamping center of the medicine bottle fixing device.

[0008] As one embodiment, the housing is provided with a medicine inlet / outlet, which is positioned directly opposite the clamping position of the medicine bottle fixing device.

[0009] In one embodiment, the mist outlet of the atomizer extends to the outside of the housing, and a face mask is provided on the housing. The face mask is detachably connected to the mist outlet of the atomizer.

[0010] As one embodiment, a handle is connected to the housing, and a battery compartment is formed inside the handle, in which a battery is installed.

[0011] As one embodiment, the bottom of the handle is provided with a battery charging port, which is electrically connected to the battery.

[0012] As one embodiment, the handle has an atomization button on its side.

[0013] As one embodiment, the housing is provided with a positioning device and a sound alarm device, both of which are electrically connected to the battery.

[0014] A drug nebulization method, using the above-mentioned drug nebulization device, includes the following steps: S1. Parameter preset and timed reminder: The nebulization time and single dose are preset. The single dose is remotely modified by an authorized external monitoring terminal and synchronized to the control unit. When the preset nebulization time is reached, the control unit triggers a reminder signal to prompt the user to perform the nebulization operation. S2. Medicine loading: Place the medicine bottle containing the medicine liquid into the medicine receiving area of ​​the shell, so that the free end of the suction tube is inserted into the medicine liquid in the medicine bottle; S3. Quantitative drug absorption: The amount of drug absorbed in a single session is preset. The control chip calculates the target stroke of the reciprocating motor output shaft based on the preset drug amount. The reciprocating motor is started, and the output shaft of the reciprocating motor drives the transmission connector to move away from the cylinder, which in turn drives the piston to slide upward along the cylinder axis. The internal volume of the cylinder increases, creating a negative pressure. The one-way valve opens into the cylinder under the pressure difference, and the drug is drawn into the cylinder through the suction tube. By controlling the stroke of the reciprocating motor output shaft, the vacuum level inside the cylinder is changed, thereby controlling the amount of drug drawn into the cylinder in a single session. S4. Nebulized drug delivery: When the amount of inhaled drug reaches the preset value, the output shaft of the reciprocating motor drives the transmission connector to move closer to the cylinder, which in turn drives the piston to slide downward along the cylinder axis. The internal volume of the cylinder decreases and the pressure increases. Under the action of internal pressure, the one-way valve automatically closes in the reverse direction, blocking the backflow path of the drug. As the piston continues to move downward, the drug in the cylinder is forced into the nebulizer through the outlet pipe. The nebulizer atomizes the drug and outputs it. S5. Reset: After the drug administration is completed, the output shaft of the reciprocating motor drives the piston back to the initial position at the bottom of the cylinder, waiting for the next working cycle.

[0015] The present invention achieves the following technical effects compared to the prior art: 1. This invention uses a reciprocating motor as a power source. The reciprocating motor drives the transmission connector to move the piston in the cylinder in a reciprocating motion. The alternating changes in the internal volume of the cylinder create negative and positive pressures. Combined with the one-way conduction characteristic of the one-way valve, the liquid medicine is drawn in, pressurized and delivered to the nebulizer for atomization. The entire process does not require the user to manually apply a large force to compress the spring, which effectively reduces the difficulty of operation and is suitable for people with less hand strength. At the same time, the reciprocating motor can precisely control the movement stroke of the output shaft, which can stably control the amount of liquid medicine inhaled and the output pressure in a single dose, solving the problem of poor dosage accuracy caused by uneven manual force in traditional devices.

[0016] Other technical solutions of the present invention also have the following technical effects: 2. This invention uses a connecting plate as the transmission connector and arranges the output shaft of the reciprocating motor and the piston axis in parallel, enabling smooth power transmission and effectively preventing piston displacement, uneven wear, and jamming during operation. This further improves the operational stability of the negative pressure generator and the accuracy of liquid dosage. The medicine bottle fixing device in the medicine containing area, combined with a suction tube facing the clamping center, reliably limits the position of the medicine bottle, ensuring stable liquid intake and preventing air intake from affecting the atomization effect. The medicine inlet and outlet, positioned directly opposite the clamping position, make the handling of medicine bottles more convenient and smooth. The atomizing generator... The mist outlet features a detachable face mask for easy disassembly, cleaning, and replacement, adapting to the needs of different users. The handle and battery compartment inside the handle enable handheld use, significantly improving overall portability. The battery charging port at the bottom of the handle allows for on-the-spot battery replenishment, ensuring continuous operation. The misting button on the side of the handle is intuitive and easy to operate, further lowering the barrier to entry. The integrated positioning and audible alarm devices within the housing assist in quickly locating the device if it is lost or obstructed by debris, comprehensively enhancing the device's overall performance, practicality, and safety.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1 This embodiment provides a drug atomizing device; please refer to [reference needed]. Figure 1 - Figure 7 The device includes a housing 1, a reciprocating motor 2, a transmission connector 3, a negative pressure generator 4, a suction pipe 5, an outlet pipe 6, a one-way valve 7, and an atomizer. The housing 1 contains independent mounting chambers and a drug-containing area. The mounting chambers house and secure the mechanical components of the device, while the drug-containing area holds drug bottles. The reciprocating motor 2 is mounted within the mounting chambers and has an output shaft capable of reciprocating in a linear direction. The axis of the output shaft is parallel to the axis of the negative pressure generator 4. The transmission connector 3 is a horizontally arranged plate-like structure, with one end fixedly connected to the end of the output shaft of the reciprocating motor 2, and the other end extending horizontally towards the negative pressure generator 4.

[0023] The negative pressure generator 4 is installed in the mounting chamber. The negative pressure generator 4 includes a cylinder and a piston. A sealed cavity is formed inside the cylinder. The piston is slidably and sealingly installed in the sealed cavity of the cylinder. The upper end of the piston extends out of the cylinder, and the piston is fixedly connected to the end of the transmission connector 3 away from the reciprocating motor 2, so that the piston can slide back and forth along the axial direction of the cylinder under the drive of the reciprocating motor 2.

[0024] The bottom of the cylinder is equipped with a suction tube 5 and a discharge tube 6, both of which are integrally formed rigid pipes at the bottom of the cylinder. Both the suction tube 5 and the discharge tube 6 have a connecting end and a free end, and the connecting end of the suction tube 5 and the connecting end of the discharge tube 6 are connected to an independent chamber within the cylinder. A one-way valve 7 is installed on the lumen of the suction tube 5, allowing fluid to flow only from the free end of the suction tube 5 towards its connecting end, and prohibiting reverse flow. The free end of the suction tube 5 extends into the drug-containing area for insertion into the drug bottle to draw the liquid medication. The free end of the discharge tube 6 is sealed to the inlet of the nebulizer, which is fixedly installed in the mounting chamber, with its mist outlet extending to the outside of the housing 1, for atomizing the liquid medication and outputting it for the patient to inhale.

[0025] The working process of the drug atomizing device in this embodiment is as follows: Quantitative drug absorption process: The medicine bottle containing the liquid medicine is placed in the medicine receiving area of ​​the shell 1, with the free end of the suction tube 5 inserted into the liquid medicine in the bottle. The reciprocating motor 2 is started, and its output shaft drives the transmission connector 3 upwards, which in turn drives the piston to slide upwards along the cylinder. At this time, the volume of the independent chamber at the bottom of the cylinder increases, creating a negative pressure inside. The one-way valve 7 opens into the cylinder under the pressure difference, and the liquid medicine is drawn into the independent chamber at the bottom of the cylinder through the suction tube 5. By controlling the upward movement distance of the output shaft of the reciprocating motor 2, the magnitude of the negative pressure and the amount of medicine absorbed in the independent chamber at the bottom of the cylinder can be precisely controlled.

[0026] Nebulized drug delivery and pressure maintenance process: When the inhaled drug volume reaches the preset value, the output shaft of the reciprocating motor 2 drives the transmission connector 3 and the piston to slide downwards, reducing the volume of the independent chamber at the bottom of the cylinder and rapidly increasing the internal pressure. At this time, the one-way valve 7 automatically closes in the reverse direction under the action of internal pressure, effectively blocking the path of the liquid medicine flowing back to the medicine bottle through the suction tube 5, so that the independent chamber at the bottom of the cylinder forms a closed pressure-maintaining space. As the piston continues to move downwards, the internal pressure continues to rise, and the liquid medicine can only be forced into the nebulizer through the outlet tube 6. The nebulizer atomizes the liquid medicine into tiny particles, which are output through its outlet for the patient to inhale.

[0027] In one embodiment, the transmission connector 3 is a connecting plate. The output shaft axis of the reciprocating motor 2 is parallel to the axis of the piston. The connecting plate is a flat plate structure, and the plane of the connecting plate is perpendicular to the output shaft axis. One end of the connecting plate is fixedly connected to the end of the output shaft of the reciprocating motor 2, and the other end of the connecting plate is fixedly connected to the end of the piston. By adopting the above-mentioned transmission structure with parallel double shafts and a perpendicular connecting plate, the linear reciprocating motion of the reciprocating motor 2 can be synchronously transmitted to the piston without deviation, effectively avoiding radial offset, uneven wear, or jamming of the piston when it moves in the cylinder, and significantly improving the motion stability and quantitative drug absorption accuracy of the negative pressure generator 4.

[0028] In one embodiment, a medicine bottle fixing device 8 is fixedly installed within the medicine containing area. The medicine bottle fixing device 8 is a flexible clamping structure used to detachably clamp and fix the medicine bottle 9. The free end of the suction tube 5 is positioned towards the clamping center of the medicine bottle fixing device 8; preferably, the axis of the suction tube 5 coincides with the clamping center axis of the medicine bottle fixing device 8. When the medicine bottle 9 is clamped and fixed on the medicine bottle fixing device 8, the free end of the suction tube 5 can automatically align and accurately insert into the center position of the bottle mouth of the medicine bottle 9, avoiding contact between the suction tube 5 and the bottle wall of the medicine bottle 9. This ensures that the suction tube 5 is always immersed in the liquid until the liquid is exhausted, effectively preventing quantitative errors caused by air intake and significantly improving the stability and accuracy of liquid suction.

[0029] In one embodiment, the nebulizer's outlet extends to the outside of the housing 1. A face mask 10 is provided at one end of the housing 1 corresponding to the nebulizer's outlet. The face mask 10 has a cup-shaped structure, and its open end is detachably connected to the nebulizer's outlet via a snap-fit ​​structure. This detachable, sealed connection structure facilitates the replacement of different sizes of face masks 10 for different users while ensuring the sealing of the nebulization channel, effectively preventing leakage of the nebulized medication and improving drug utilization. As the piston continues to move downwards, the internal pressure continuously increases, and the medication is forced into the nebulizer through the outlet pipe 6. The nebulizer atomizes the medication into tiny particles, which enter the face mask 10 through its outlet for the patient to inhale.

[0030] In one embodiment, a handle 11 is provided at the bottom of the housing 1. The handle 11 has a hollow cylindrical structure, and an independent battery compartment is formed axially inside the handle 11, in which a battery is installed. The battery is preferably a rechargeable battery, which is electrically connected to the reciprocating motor 2 and the atomizing generator respectively, to provide power for the operation of the entire device. A battery charging port 12 is provided at the bottom of the handle 11, which is electrically connected to the battery and is used to replenish the rechargeable battery with power from an external power source. By integrating the battery compartment inside the handle 11, the device can be easily operated by hand, and the internal space of the handle 11 is fully utilized, making the overall structure of the device more compact, easy to carry and use.

[0031] In one embodiment, the housing 1 is provided with a medicine inlet / outlet 13. The medicine inlet / outlet 13 is a circular opening, used for inserting or removing the medicine bottle 9 into the medicine containing area. The center of the medicine inlet / outlet 13 is directly opposite to the clamping center of the medicine bottle fixing device 8, and the axis of the medicine inlet / outlet 13 coincides with the clamping center axis of the medicine bottle fixing device 8. When the medicine bottle 9 is inserted into the medicine containing area through the medicine inlet / outlet 13, it can automatically align with the clamping center of the medicine bottle fixing device 8 and be stably clamped and fixed by the medicine bottle fixing device 8. At the same time, it ensures that the free end of the suction tube 5 can be accurately inserted into the center position of the bottle mouth of the medicine bottle 9, ensuring the stability and quantitative accuracy of the entire suction process.

[0032] In one embodiment, the front of the housing 1 is provided with a display screen 14 and multiple parameter setting buttons 15. The multiple parameter setting buttons 15 are arranged side-by-side on one side of the display screen 14, and are evenly spaced in a row along the axis of the handle 11. Each parameter setting button 15 includes up / down page buttons and a confirmation button. This human-computer interaction structure, combining physical buttons with a display screen, avoids the drawbacks of pure touchscreen operation, such as high precision requirements and susceptibility to accidental touches. It significantly lowers the operational threshold, making it suitable for elderly users and other users with operational difficulties, and improves the ease of operation and reliability of the device. The display screen 14 is used to intuitively display the device's working status, remaining medication, and set operating parameters; the parameter setting buttons 15 can be used to adjust operating parameters such as the amount of nebulization per cycle and the nebulization time, as well as auxiliary functions such as binding remote assistance personnel information.

[0033] In one embodiment, a push-button atomization button 16 is provided on the side of the handle 11. Pressing the atomization button 16 triggers the device to start a complete atomization cycle. By adopting a separately designed physical atomization button structure, the atomization start function and parameter setting function are physically separated, making the operation logic intuitive and clear. At the same time, it enables one-button quick start of atomization, greatly improving the ease of operation of the device.

[0034] In one embodiment, the mounting cavity of the housing 1 is equipped with a positioning device and an audible alarm device. Both the positioning device and the audible alarm device are electrically connected to the battery. When the device is lost or obstructed by debris and difficult to find, the approximate location of the device can be obtained through the positioning device, and then the prompt sound emitted by the audible alarm device can be used for close-range and precise location, improving the recoverability of the device.

[0035] In one embodiment, the mask 10 and the mist outlet of the housing 1 are connected by a detachable sealed structure, allowing for the replacement of different sizes of mask 10 according to different users. A wireless communication module is installed in the mounting chamber of the housing 1, and this module is electrically connected to the battery. A data storage module is also installed in the mounting chamber of the housing 1, and this module is electrically connected to the wireless communication module, the display screen 14, and the reciprocating motor 2. The detachable mask 10 facilitates cleaning, disinfection, and replacement, meeting the needs of patients of different ages and facial shapes, and improving hygiene and comfort. The wireless communication module can establish a communication connection with external terminal devices to receive and send medication reminder information, helping patients take their medication on time. Authorized external terminal devices can transmit preset nebulization operating parameters to the data storage module via the wireless communication module, allowing parameter settings to be completed without manual operation by the patient, making it suitable for the elderly or those with limited operational abilities. The data storage module can store preset timed and quantitative operating parameters, ensuring the device operates only according to these preset parameters, effectively preventing inaccurate dosages caused by patients adjusting parameters themselves, and guaranteeing treatment effectiveness.

[0036] In one embodiment, a base is fixedly mounted on the bottom of the reciprocating motor 2, and a control chip 17 is fixedly mounted on the lower surface of the base, directly below the reciprocating motor 2. The control chip 17 is entirely housed within the mounting cavity of the housing 1. The control chip 17 is electrically connected to the reciprocating motor 2, the atomizer, the display screen 14, the parameter setting button 15, the atomization button 16, and the battery. The control chip 17 can receive operation signals from the parameter setting button 15 and the atomization button 16, and, in conjunction with preset parameters, uniformly regulate the start / stop and operating status of the reciprocating motor 2 and the atomizer. Simultaneously, the control chip 17 provides real-time feedback to the display screen 14 on the device's operating status, remaining liquid level, and set parameters, coordinating the collaborative work of all electrical components to ensure the stable and orderly operation of the entire atomization device according to the set process.

[0037] Example 2 This embodiment provides a drug atomization method, using the drug atomization device in Embodiment 1, including the following steps: S1. Initial state preparation: When the device is in standby state, the piston is located at the bottom of the cylinder, the independent chamber at the bottom of the cylinder has the smallest volume, and the one-way valve 7 is in the closed state.

[0038] S2. Medicine Loading: The medicine bottle 9 containing the liquid medicine is inserted into the medicine receiving area through the medicine inlet / outlet 13 on the side of the housing 1. Since the axis of the medicine inlet / outlet 13 coincides with the clamping center axis of the medicine bottle fixing device 8, the medicine bottle 9 automatically aligns with the clamping center and is elastically clamped and fixed by the medicine bottle fixing device 8. At this time, the free end of the suction tube 5 automatically and accurately inserts into the center position of the mouth of the medicine bottle 9 and is immersed in the liquid medicine.

[0039] S3. Operating Parameter Settings: Operate via the parameter setting button 15 on the front of the housing 1. View and set operating parameters such as nebulization volume and nebulization time on the display screen 14. Save the settings to the control chip 17 by pressing the confirmation button. Authorized monitoring terminals can remotely modify nebulization operating parameters such as single-dose drug intake via the wireless communication module. Modified parameters are automatically synchronized to the control unit and take effect. For remote assistance, authorized remote assistance personnel information can be bound via the parameter setting button 15.

[0040] S4. Atomization Start: Press the atomization button 16 on the side of the handle 11. The control unit first verifies the time interval between the current start and the previous atomization operation. If it is determined to be an illegal repeated start, the sound alarm device will be triggered to issue an alarm, and a warning message will be sent to the authorized monitoring terminal through the wireless communication module. After the verification is passed, the trigger device will start a complete atomization operation cycle.

[0041] S5. Quantitative drug absorption process: The reciprocating motor 2 starts, and its output shaft drives the transmission connector 3 to move upward, which in turn drives the piston to slide upward along the cylinder axis. At this time, the volume of the independent chamber at the bottom of the cylinder increases, and a negative pressure is formed inside. The one-way valve 7 opens into the cylinder under the action of the pressure difference, and the drug solution is drawn into the independent chamber at the bottom of the cylinder through the suction pipe 5. By controlling the upward movement distance of the output shaft of the reciprocating motor 2, the amount of drug solution drawn into the cylinder can be precisely controlled.

[0042] S6. Nebulized Drug Delivery and Pressure Holding Process: When the inhaled drug volume reaches the preset value, the reciprocating motor 2 automatically reverses direction, and its output shaft drives the transmission connector 3 and piston to slide downwards. At this time, the volume of the independent chamber at the bottom of the cylinder decreases, and the internal pressure rises rapidly. Under the action of internal pressure, the one-way valve 7 automatically closes in the reverse direction, completely blocking the path of the liquid medicine flowing back to the medicine bottle 9 through the suction tube 5, thus forming a closed pressure holding space at the bottom of the cylinder. As the piston continues to move downwards, the internal pressure continues to rise, and the liquid medicine is forced into the nebulizer through the only outlet pipe 6. The nebulizer atomizes the liquid medicine into tiny particles, which enter the mask 10 through its mist outlet for the patient to inhale.

[0043] S7. Cycle End and Reset: After the preset atomization amount is fully output, the reciprocating motor 2 stops running, and its output shaft drives the piston back to the initial position at the bottom of the cylinder. The device automatically returns to the standby state, waiting for the next atomization cycle.

[0044] S8. Additional Function Execution: When the preset nebulization time point is reached, the control unit triggers a prompt sound to remind the user to start the nebulization device for treatment at regular intervals; authorized remote assistance personnel can remotely modify the device's nebulization operation parameters through the wireless communication module, and the modified parameters are automatically saved to the data storage module and take effect; when the device is lost or obstructed by debris and difficult to find, the positioning device and sound alarm device can be triggered through an external terminal to obtain the device's location and conduct a close-range search through the prompt sound.

The reciprocating motor (2) is started, and the output shaft of the reciprocating motor (2) drives the transmission connector (3) to move away from the cylinder, thereby driving the piston to slide upward along the cylinder axis. The internal volume of the cylinder increases to form a negative pressure, and the one-way valve (7) opens into the cylinder under the action of the pressure difference. The drug liquid is sucked into the cylinder through the suction tube (5). By controlling the motion stroke of the output shaft of the reciprocating motor (2), the vacuum degree in the cylinder is changed, thereby controlling the amount of drug liquid sucked into the cylinder in a single session. S4, Nebulized drug delivery: When the amount of inhaled drug reaches the preset value, the output shaft of the reciprocating motor (2) drives the transmission connector (3) to move closer to the cylinder, which in turn drives the piston to slide downward along the cylinder axis. The internal volume of the cylinder decreases and the pressure increases. The one-way valve (7) automatically closes in the reverse direction under the action of internal pressure, blocking the return path of the drug. As the piston continues to move downward, the drug in the cylinder is forced into the nebulizer through the outlet pipe (6). The nebulizer atomizes the drug and outputs it. S5. Reset: After the drug is administered, the output shaft of the reciprocating motor (2) drives the piston back to the initial position at the bottom of the cylinder, waiting for the next working cycle.
