Description

Technical Field

[0001] The present invention relates to the technical field of atomizers, and specifically to a high-frequency current mechanical oscillation particle atomization device. Background Art

[0002] A medical atomizer is a class II medical device used for the treatment of respiratory diseases. Its core function is to convert liquid medicine into micron-sized aerosol particles, enabling patients to directly inhale the medicine into the affected area through breathing.

[0003] Chinese Patent CN219462196U discloses an atomizing inhaler for patients assisted by a non-invasive ventilator. Through the setting of a flow disturbance component, when a medical staff rotates a rotating rod to drive a flow disturbance plate to rotate and deflect, the flow disturbance plate can contact oxygen and atomized medicine at different angles, making the flow rates of the medicine and oxygen smoother, which is more convenient for patients to inhale and improves the patients' usage experience. However, in actual use, different patients and different diseases have different requirements for the amount of medicine inhaled each time. This device making the airflow carrying the medicine flow smoother through the flow disturbance plate cannot change the amount of medicine carried in the airflow, resulting in patients not receiving precise treatment, bringing inconvenience to the patients' treatment. At the same time, it is unable to precisely control the amount of medicine that needs to be atomized during the treatment process, causing the excess medicine not to be absorbed by the patients, increasing the consumption of drugs, and thus resulting in waste of medicine.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1; Please refer to Figures 1-8, a high-frequency current mechanical oscillation particle atomization device, comprising a housing 1, on which a drug delivery mechanism 2 and an atomization assembly 5 are provided. The drug delivery mechanism 2 includes a medicine cup 201, an adjustment assembly 3 and a stirring assembly 4. The medicine cup 201 is installed on the upper side of the housing 1. A support column 21 is connected inside the medicine cup 201. An outlet 2111 is provided at the lower end of the support column 21. A cup cover 23 is provided at the upper end of the medicine cup 201, and a knob 24 is connected to the cup cover 23. The adjustment assembly 3 includes a push rod 31, which is installed inside the support column 21 and above the outlet 2111. A sealing plug 311 is connected to the lower end of the push rod 31. When the medicine cup 201 is installed on the housing 1, the upper end of the push rod 31 penetrates through the cup cover 23 and is connected to the knob 24. By rotating the knob 24, the push rod 31 can be driven to drive the sealing plug 311 to move vertically, adjusting the size of the outlet 2111. The stirring assembly 4 includes a rotating cylinder 41 and a transmission rod 44. The rotating cylinder 41 is sleeved on the upper end of the support column 21, and a stirring paddle 42 is connected to the rotating cylinder 41. The transmission rod 44 is installed at the lower end of the support column 21 and cooperates with the rotating cylinder 41. During atomization, the transmission rod 44 can drive the rotating cylinder 41 to rotate, so that the rotating cylinder 41 drives the stirring paddle 42 to stir the medicine in the medicine cup 201. The atomization assembly 5 includes an atomization head 51 and an infusion pipeline 54. When the atomization head 51 is connected to the medicine cup 201 installed on the housing 1 through the infusion pipeline 54, the sealing plug 311 moves upward to open the outlet 2111.

[0021] Among them, when in use, first dock the device with the ventilator, install the transparent medicine cup 201 filled with medicine on the housing 1, then turn on the power supply to perform the atomization of the medicine. When the medicine cup 201 is docked with the infusion pipeline 54, the end of the infusion pipeline 54 docked with the medicine cup 201 pushes the sealing plug 311 upward, opening a small part of the liquid outlet 2111. The liquid outlet 2111 transports the medicine in the medicine cup 201 into the atomizing head 51 at the minimum flow rate for atomization. The atomized medicine will be mixed into the oxygen delivered by the ventilator and enter the patient's body along with the oxygen. At this time, the medicine content in the oxygen is in the minimum state. At the same time, the upward moving sealing plug 311 synchronously pushes the push rod 31, connecting the push rod 31 with the knob 24. When it is necessary to increase the medicine content in the oxygen, by rotating the knob 24 in the reverse direction, the push rod 31 is driven to drive the sealing plug 311 to rotate synchronously. During the rotation of the push rod 31, the sealing plug 311 is pulled upward, gradually opening the remaining part of the liquid outlet 2111, thereby increasing the flow rate of the liquid outlet 2111 to output the medicine to the atomizing head 51, increasing the medicine content in the oxygen. After the medicine content carried by the oxygen fits the patient, stop rotating the knob 24. When the liquid outlet 2111 is completely opened, the flow rate of the medicine flowing into the atomizing head 51 is the largest, and the atomized medicine content carried by the oxygen is the highest. The transparent medicine cup 201 enables medical staff to accurately control the opening degree of the liquid outlet 2111 when adjusting the medicine flow rate. And during the atomization process, with the device turned on, the transmission rod 44 starts to drive the rotating cylinder 41 to rotate, so that the rotating cylinder 41 drives the stirring paddle 42 to stir the medicine in the medicine cup 201, preventing the medicine from precipitating in the medicine cup 201 during the atomization process and remaining in the device, enabling the medicine to fully play its role. After the treatment is completed, turn off the device to end the atomization work, the stirring assembly 4 stops operating, then remove the medicine cup 201, and disinfect and clean the used medicine cup 201. During this process, the liquid outlet 2111 is in the open state, facilitating the cleaning by medical staff. After the cleaning is completed and the medicine cup 201 is dried, turn the knob 24 clockwise. During the process of driving the sealing plug 311 to rotate in the same direction by the push rod 31, push the sealing plug 311 downward. When the sealing plug 311 closes the liquid outlet 2111 to the minimum state, stop rotating the knob 24. As the medicine cup 201 is disconnected from the infusion channel, the push rod 31 will automatically push the sealing plug 311 downward to completely close the liquid outlet 2111 and disconnect it from the knob 24, waiting for the next use.

[0022] The difference from the above embodiment is that the bottom inside the medicine cup 201 is an inclined plane, in a funnel shape. The lower part of the support column 21 is in a cam shape with one end large and the other end small. The upper part of the support column 21 is columnar and located on the upper side of the large end of its lower part. The lower part of the support column 21 is fixedly installed at the exact center of the funnel-shaped bottom of the medicine cup 201. The top end of the lower part of the support column 21 is fixedly connected with a sealing cover 25. An adjusting cavity 211 and a transmission groove 212 are successively formed inside the lower part of the support column 21. The adjusting cavity 211 and the transmission groove 212 are respectively located on the large-end side and the small-end side of the lower part of the support column 21. And the adjusting cavity 211, the upper part of the support column 21 and the medicine cup 201 are on the same axis. A liquid outlet 2111 is opened on one side of the lower end of the adjusting cavity 211 away from the transmission groove 212, so that the adjusting cavity 211 is communicated with the inside of the medicine cup 201. The lower end of the medicine cup 201 is fixedly installed with a docking head 22. An external thread is provided on the outside of the docking head 22. A docking groove 221 is opened at the bottom of the docking head 22. The upper end of the docking groove 221 is communicated with the adjusting cavity 211. The upper and lower ends of the transmission groove 212 respectively penetrate through the top end of the lower part of the support column 21 and the lower side of the docking head 22.

[0023] Among them, the sealing cover 25 isolates its interior from the outside world, preventing the medicine in the medicine cup 201 from seeping into the device through the transmission groove 212, which may affect the normal operation of the device and cause waste of the medicine.

[0024] The difference from the above embodiment is that the upper end of the cup cover 23 is fixedly connected with a connecting sleeve 231. The connecting sleeve 231 corresponds to the adjusting cavity 211. An internal thread is provided on the inner wall of the lower end of the connecting sleeve 231. An annular convex block 232 is fixedly connected to the outer side of the top end of the connecting sleeve 231. The cup cover 23 is assembled on the medicine cup 201 by threads. A sliding groove 241 is formed inside the knob 24. The sliding groove 241 is slidably connected with the upper end of the connecting sleeve 231. A clamping block 242 is fixedly connected to the top end of the sliding groove 241. The clamping block 242 is in a cross shape.

[0025] Among them, when the cup lid 23 is unscrewed to add medicine to the medicine cup 201, as the cup lid 23 is unscrewed, the upper end of the push rod 31 is pulled out from the connecting sleeve 231. When the cup lid 23 is screwed back onto the medicine cup 201, the upper end of the push rod 31 is inserted back into the connecting sleeve 231. When the push rod 31 pushes the sealing plug 311 to block the liquid outlet 2111, the top of the push rod 31 is located below the locking block 242 and does not contact the locking block 242. When the medicine cup 201 is connected to the infusion channel to initially open the liquid outlet 2111, the push rod 31 moves upward, and the locking block 242 thus inserts into the push rod 31, enabling the knob 24 to rotate the push rod 31. When the knob 24 is rotated in the reverse direction, the rising push rod 31 will push up the knob 24, causing the bottom of the sliding groove 241 to approach the convex block 232. When the liquid outlet 2111 is fully opened, the convex block 232 abuts against the bottom of the sliding groove 241, preventing the push rod 31 from continuing to push the knob 24 upward and preventing the push rod 31 from moving excessively and damaging the device.

[0026] The difference from the above embodiment is that the sealing plug 311 is slidably installed in the adjustment cavity 211. The upper end of the sealing plug 311 is fixedly connected to the lower end of the push rod 31. The upper end of the push rod 31 slidably penetrates through the support column 21. A pressing spring 32 is sleeved on the push rod 31. The two ends of the pressing spring 32 respectively abut against the top of the adjustment cavity 211 and the upper end of the sealing plug 311. A clamping groove 312 is formed at the top of the push rod 31, and the clamping groove 312 corresponds to the locking block 242. When the medicine cup 201 is installed on the housing 1, the upper end of the push rod 31 is inserted into the connecting sleeve 231 and extends into the knob 24, and the locking block 242 is embedded in the clamping groove 312. An external thread that fits the internal thread of the connecting sleeve 231 is provided on the outer side of the upper end of the push rod 31.

[0027] Among them, when the liquid outlet 2111 is completely closed, the pressing spring 32 applies pressure to the sealing plug 311, causing the sealing plug 311 to abut against the bottom of the adjustment chamber 211, blocking the liquid outlet 2111. At this time, the card slot 312 of the push rod 31 is disengaged from the card block 242 of the knob 24, and the upper end of the external thread of the push rod 31 is separated from the lower end of the internal thread of the connecting sleeve 231. When the infusion pipeline 54 is connected to the medicine cup 201, with the initial opening of the liquid outlet 2111, the push rod 31 moves upward under the push of the sealing plug 311, embedding the card block 242 into the card slot 312, and bringing the upper end of the external thread close to the lower end of the internal thread of the connecting sleeve 231 to coincide, and compressing the pressing spring 32. When it is necessary to further open the liquid outlet 2111, the knob 24 drives the push rod 31 to rotate in the reverse direction through the cooperation of the card block 242 and the card slot 312, so that the push rod 31 drives the sealing plug 311 to move upward under the cooperation of the thread, thereby further opening the liquid outlet 2111, and at the same time the pressing spring 32 is further compressed. When the medicine cup 201 is detached from the infusion pipeline 54 and it is necessary to close the liquid outlet 2111, the knob 24 is rotated in the forward direction, so that the push rod 31 drives the sealing plug 311 to move downward under the cooperation of the thread. After the thread of the push rod 31 is disengaged from the thread of the connecting sleeve 231, the compressed pressing spring 32 pushes the sealing plug 311 to abut against the bottom of the adjustment chamber 211, thereby completely closing the liquid outlet 2111.

[0028] The difference from the above embodiment is that the rotating cylinder 41 is rotatably installed on the upper part of the columnar support column 21, and the upper end of the rotating cylinder 41 penetrates through the sealing cover 25 and extends to the lower side of the connecting sleeve 231. A plurality of stirring paddles 42 are circumferentially distributed on the outside of the rotating cylinder 41 and are fixedly connected to the rotating cylinder 41. A driven gear 43 is fixedly connected to the lower end of the rotating cylinder 41 located inside the sealing cover 25. The transmission rod 44 is rotatably installed in the transmission groove 212. A transmission gear 45 is fixedly connected to one end of the transmission rod 44 extending into the sealing cover 25. The driven gear 43 and the transmission gear 45 are connected by a toothed belt 49. A transmission bevel gear 46 is fixedly connected to the lower end of the transmission rod 44. The transmission bevel gear 46 is located below the docking head 22.

[0029] Among them, when the device is powered on, the transmission bevel gear 46 drives the transmission rod 44 to drive the transmission gear 45 to rotate. The rotating transmission gear 45 drives the driven gear 43 to rotate through the toothed belt, so that the driven gear 43 drives the rotating cylinder 41 to drive the stirring paddle 42 to rotate in the medicine cup 201 to stir the medicine.

[0030] The difference from the above embodiment is that the stirring assembly 4 further includes a driving motor 47. The driving motor 47 is fixedly installed in the housing 1, on the side of the docking head 22 away from the atomization assembly 5. A driving bevel gear 48 is coaxially and fixedly connected to the output shaft of the driving motor 47. The driving bevel gear 48 meshes with the transmission bevel gear 46.

[0031] Among them, after the device is powered on, the driving motor 47 drives the transmission bevel gear 46 to rotate through the driving bevel gear 48.

[0032] The difference from the above embodiment is that a docking port 11 is provided on the upper side of the housing 1, the docking head 22 is installed in the docking port 11 by means of threads, and a connection port 12 is fixedly installed on one side of the handle portion of the housing 1.

[0033] Among them, when cooperating with a ventilator, the air delivery pipe of the ventilator is docked with the connection port 12.

[0034] The difference from the above embodiment is that the atomizing head 51 is fixedly connected to the end of the housing 1. An atomizing chamber 511 is provided in the atomizing head 51. A vibrating mesh screen 52 is fixedly installed at one end of the atomizing chamber 511 close to the medicine cup 201. A piezoelectric transducer 53 is fixedly connected to the bottom on the side of the vibrating mesh screen 52 close to the medicine cup 201. One end of the infusion pipeline 54 is docked with the vibrating mesh screen 52, and a pipeline joint 55 is fixedly connected to the other end of the infusion pipeline 54. The pipeline joint 55 corresponds to the docking groove 221, and a top block 56 is fixedly installed in the pipeline joint 55.

[0035] Among them, when the docking head 22 of the medicine cup 201 is docked with the docking port 11, the pipeline joint 55 will be inserted into the docking groove 221, and the top block 56 on the pipeline joint 55 will push up the sealing plug 311, thus initially opening the liquid outlet 2111. When the medicine cup 201 is separated from the infusion pipeline 54, the pipeline joint 55 is withdrawn from the docking groove 221, and the top block 56 is separated from the sealing plug 311. After the device is powered on, the piezoelectric transducer 53 drives the vibrating mesh screen 52 to generate high-frequency mechanical vibration under the action of current, so as to atomize the medicine delivered by the infusion pipeline 54 into small droplets and enter the atomizing chamber 511, and spray out from the atomizing head 51 and be inhaled by the patient.

[0036] The difference from the above embodiment is that the connection port 12 is fixedly connected to one end of the air delivery pipeline 6, and the other end of the air delivery pipeline 6 is fixedly connected to the atomizing head 51, communicating with the atomizing chamber 511 and located on the side of the vibrating mesh screen 52 away from the medicine cup 201.

[0037] Among them, after the connection port 12 is docked with the air delivery pipe of the ventilator, the oxygen output by the ventilator enters the atomizing chamber 511 through the air delivery pipeline 6, mixes with the medicine atomized by the vibrating mesh screen 52, and the atomized medicine carried is inhaled by the patient.

[0038] Embodiment 2; The difference from the above embodiment is that a mouth-nose mask 7 is fixedly connected to the end of the atomizing head 51 away from the housing 1.

[0039] Among them, when the patient is undergoing atomization treatment, wearing the mouth-nose mask 7 can facilitate the patient to inhale.

[0040] Working principle: When in use, first connect the air delivery pipe of the ventilator to the connection port 12. The oxygen output by the ventilator enters the atomization chamber 511 through the air delivery pipe 6. Then install the transparent medicine cup 201 filled with medicine on the housing 1, and then turn on the power supply to perform the atomization of the medicine. When the medicine cup 201 is docked with the infusion pipe 54, the pipe joint 55 will insert into the docking groove 221. The top block 56 on the pipe joint 55 will push up the sealing plug 311, opening a small part of the liquid outlet 2111. The liquid outlet 2111 delivers the medicine in the medicine cup 201 to the atomizing head 51 at the minimum flow rate for atomization. During this process, the piezoelectric transducer 53 drives the vibrating mesh 52 to generate high-frequency mechanical vibration under the action of current, atomizing the medicine delivered by the infusion pipe 54 into small droplets and entering the atomization chamber 511, mixing with the oxygen delivered by the ventilator and being inhaled into the patient's body by the patient. At this time, the medicine content in the oxygen is in the minimum state. At the same time, the upward-moving sealing plug 311 synchronously pushes the push rod 31, embedding the locking block 242 into the card slot 312, and making the upper end of the external thread close to the lower end of the internal thread of the connecting sleeve 231 coincide, and compressing the pressing spring 32. When it is necessary to increase the medicine content in the oxygen, the push rod 31 drives the sealing plug 311 to move upward under the cooperation of the threads, further opening the liquid outlet 2111. At the same time, the pressing spring 32 is further compressed, opening the remaining part of the liquid outlet 2111, thereby increasing the flow rate of the medicine output from the liquid outlet 2111 to the atomizing head 51 and increasing the medicine content in the oxygen. When the medicine content carried by the oxygen fits the patient, stop turning the knob 24. When the liquid outlet 2111 is fully opened, the flow rate of the medicine flowing into the atomizing head 51 is the largest, and the content of the atomized medicine carried by the oxygen is the highest. The transparent medicine cup 201 enables medical staff to accurately control the opening degree of the liquid outlet 2111 when adjusting the medicine flow rate; And during the atomization process, with the device powered on, the drive motor 47 drives the rotating cylinder 41 to rotate through the transmission rod 44, so that the rotating cylinder 41 drives the stirring paddle 42 to stir the medicine in the medicine cup 201, preventing the medicine from precipitating in the medicine cup 201 during the atomization process and remaining in the device, enabling the medicine to fully play its role. After the treatment is completed, turn off the device to end the atomization work, stop the operation of the stirring assembly 4, then remove the medicine cup 201, and disinfect and clean the used medicine cup 201. During this process, not rotating the knob 24 forward will close the liquid outlet 2111, keeping the liquid outlet 2111 in an open state for the convenience of medical staff to clean. After the cleaning is completed and the medicine cup 201 is dried, then turn the knob 24 forward, so that the push rod 31 drives the sealing plug 311 to move downward under the cooperation of the threads. After the threads of the push rod 31 are disengaged from the threads of the connecting sleeve 231, the compressed pressing spring 32 pushes the sealing plug 311 to contact the bottom of the adjustment cavity 211, thereby completely closing the liquid outlet 2111 and disconnecting it from the knob 24, waiting for the next use.
