Description

Technical Field

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

[0002] A medical nebulizer is a Class II medical device used to treat respiratory diseases. Its core function is to convert liquid drugs into micron-sized aerosol particles, allowing patients to inhale them directly into the lesion site through breathing.

[0003] Chinese patent CN219462196U discloses a nebulizer inhaler for patients with non-invasive ventilator-assisted breathing. Through the setting of the spoiler component, when the medical staff rotates the rotating rod to drive the spoiler to rotate and deflect, the spoiler can contact the oxygen and the atomized medicine at different angles, making the flow rate of the medicine and oxygen smoother, more convenient for the patient to inhale, and improving the patient's user experience. However, in actual use, different patients and different diseases have different requirements for the content of the medicine in each inhalation. The device uses the spoiler to make the flow rate of the airflow carrying the medicine smoother but cannot change the content of the medicine carried in the airflow, so that the patient cannot receive accurate treatment, which brings inconvenience to the patient's treatment. At the same time, it cannot accurately control the content of the medicine that needs to be atomized during the treatment process, so that the excess medicine is not absorbed by the patient, increasing the consumption of the medicine, thereby causing waste of medicine.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Embodiment 1;

[0029] See also Figures 1-8A high-frequency current mechanical oscillation particle atomization device includes a shell 1, on which a dosing mechanism 2 and an atomizing assembly 5 are provided. The dosing 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 shell 1. A support column 21 is connected to the medicine cup 201. A liquid outlet 2111 is opened at the lower end of the support column 21. A cup cover 23 is provided at the upper end of the medicine cup 201. A knob 24 is connected to the cup cover 23. The adjustment assembly 3 includes a push rod 31. The push rod 31 is installed in the support column 21 and is located above the liquid outlet 2111. The lower end of the push rod 31 is connected to a sealing plug 311. When the medicine cup 201 is installed on the shell 1, the upper end of the push rod 31 passes through the cup cover 23 and is connected to the knob 24. By turning the knob 24, the push rod 31 can be driven to drive the sealing plug 311 to move vertically to adjust the size of the liquid outlet 2111. The stirring assembly 4 includes a rotating drum 41 and a transmission rod 44. The rotating drum 41 is sleeved on the upper end of the support column 21. The rotating drum 41 is connected to a stirring paddle 42. The transmission rod 44 is installed at the lower end of the support column 21 and cooperates with the rotating drum 41. When atomization is performed, the transmission rod 44 can drive the rotating drum 41 to rotate, so that the rotating drum 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 pipe 54. When the atomization head 51 is connected to the medicine cup 201 installed on the housing 1 through the infusion pipe 54, the sealing plug 311 moves up to open the liquid outlet 2111.

[0030] When in use, the device is first docked with the ventilator, and the transparent medicine cup 201 filled with medicine is installed on the housing 1, and then the power is turned on to perform the atomization of the medicine. When the medicine cup 201 is docked with the infusion pipe 54, the end of the infusion pipe 54 docked with the medicine cup 201 pushes the sealing plug 311 to move upward, and the liquid outlet 2111 is opened a little bit. The liquid outlet 2111 delivers the medicine in the medicine cup 201 to the atomizing head 51 at a minimum flow rate for atomization. The atomized medicine will be mixed with 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 at a minimum state, and the medicine is discharged to the patient. When the medicine content in the oxygen is increased, the upward sealing plug 311 synchronously pushes the push rod 31, so that the push rod 31 is connected to the knob 24. When it is necessary to increase the medicine content in the oxygen, the knob 24 is rotated in the opposite direction to drive the push rod 31 to drive the sealing plug 311 to rotate synchronously. The push rod 31 pulls the sealing plug 311 upward during the rotation process, gradually 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, thereby increasing the medicine content in the oxygen. After the medicine content carried in the oxygen matches that of the patient, the knob 24 is stopped. When the liquid outlet 2111 is fully opened, the liquid flows into the atomizing head 51 The medicine flow is the largest, and the atomized medicine content carried by 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. In the atomization process, as the device is powered on, the transmission rod 44 starts to drive the drum 41 to rotate, so that the drum 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, so that the medicine can fully play its role. After the treatment is completed, the device is turned off to end the atomization work, the stirring component 4 stops running, and then the medicine cup is removed. 201, disinfect and clean the used medicine cup 201. During this process, the liquid outlet 2111 is in an open state to facilitate cleaning by medical staff. After cleaning is completed and the medicine cup 201 is dried, turn the knob 24 forward to make the push rod 31 drive the sealing plug 311 to rotate in the same direction, and push the sealing plug 311 downward. When the sealing plug 311 closes the liquid outlet 2111 to the minimum state, stop turning 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.

[0031] The difference from the above embodiment is that the bottom of the medicine cup 201 is an inclined surface and funnel-shaped, the lower part of the support column 21 is in the shape of a cam with one end larger than the other end, the upper part of the support column 21 is in the shape of a column and is located on the upper side of the large end of the lower part, the lower part of the support column 21 is fixedly installed in the 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 to the sealing cover 25, and the lower part of the support column 21 is sequentially provided with an adjustment cavity 211 and a transmission groove 212, which are respectively located on the large end side and the small end side of the lower part of the support column 21. The regulating chamber 211, the upper part of the support column 21 and the medicine cup 201 are located on the same axis, and the liquid outlet 2111 is opened on the side of the lower end of the regulating chamber 211 away from the transmission groove 212, so that the regulating chamber 211 is connected with the interior of the medicine cup 201, and the lower end of the medicine cup 201 is fixedly installed with a docking joint 22, the outside of the docking joint 22 is provided with an external thread, and the bottom of the docking joint 22 is provided with a docking groove 221, the upper end of the docking groove 221 is connected with the regulating chamber 211, and the upper and lower ends of the transmission groove 212 respectively pass through the top of the lower part of the support column 21 and the lower side of the docking joint 22.

[0032] The sealing cover 25 isolates the interior from the outside, thereby preventing the medicine in the medicine cup 201 from penetrating into the interior of the device through the transmission groove 212, thereby affecting the normal operation of the device and wasting the medicine.

[0033] The difference from the above embodiment is that a connecting sleeve 231 is fixedly connected to the upper end of the cup cover 23, the connecting sleeve 231 corresponds to the adjusting chamber 211, an internal thread is provided on the inner wall of the lower end of the connecting sleeve 231, and an annular protrusion 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 through threads, and a sliding groove 241 is provided in the knob 24. The sliding groove 241 is slidably connected to the upper end of the connecting sleeve 231, and a clamping block 242 is fixedly connected to the top of the sliding groove 241, and the clamping block 242 is cross-shaped.

[0034] When the cup cover 23 is opened and medicine is added to the medicine cup 201, the upper end of the push rod 31 is pulled out from the connecting sleeve 231 as the cup cover 23 is unscrewed. When the cup cover 23 is screwed back onto the medicine cup 201, the upper end of the push rod 31 is reinserted 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 block 242 and does not contact the block 242. When the medicine cup 201 is connected to the infusion channel, the liquid outlet 2111 is blocked. When 111 is initially opened, the push rod 31 moves upward, and the block 242 is inserted into the push rod 31, so that the knob 24 can rotate the push rod 31. When the knob 24 is turned in the opposite direction, the rising push rod 31 will push up the knob 24, so that the bottom of the sliding groove 241 is close to the protrusion 232. When the liquid outlet 2111 is fully opened, the protrusion 232 contacts the bottom of the sliding groove 241, preventing the push rod 31 from continuing to push the knob 24 to rise, thereby preventing the push rod 31 from excessive movement and causing damage to the device.

[0035] The difference from the above embodiment is that the sealing plug 311 is slidably installed in the adjusting chamber 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 slides through the support column 21, and a pressure spring 32 is provided on the push rod 31. The two ends of the pressure spring 32 respectively abut against the top of the adjusting chamber 211 and the upper end of the sealing plug 311, and a card slot 312 is provided on the top of the push rod 31, and the card slot 312 corresponds to the card block 242. When the medicine cup 201 is installed on the shell 1, the upper end of the push rod 31 is inserted into the connecting sleeve 231, extends into the knob 24, and the card block 242 is embedded in the card slot 312. The outer side of the upper end of the push rod 31 is provided with an external thread that matches the internal thread of the connecting sleeve 231.

[0036] When the bottle 2111 is fully opened, the push rod 31 moves upward under the push of the sealing plug 311, and the block 242 is embedded in the groove 312, so that the upper end of the outer thread is close to the lower end of the inner thread of the connecting sleeve 231 and the pressing spring 32 is compressed. When the liquid outlet 2111 is opened, the knob 24 drives the push rod 31 to rotate in the opposite direction through the cooperation of the block 242 and the slot 312, so that the push rod 31 drives the sealing plug 311 to move upward with the cooperation of the thread, thereby further opening the liquid outlet 2111, and at the same time the pressure spring 32 is further compressed. When the medicine cup 201 is separated from the infusion pipe 54 and the liquid outlet 2111 needs to be closed, the knob 24 is rotated forward so that the push rod 31 drives the sealing plug 311 to move downward with the cooperation of the thread. After the thread of the push rod 31 is separated from the thread of the connecting sleeve 231, the compressed pressure spring 32 pushes the sealing plug 311 to contact the bottom of the regulating chamber 211, thereby completely closing the liquid outlet 2111.

[0037] The difference from the above embodiment is that the rotating drum 41 is rotatably mounted on the columnar upper part of the support column 21, and the upper end of the rotating drum 41 passes through the sealing cover 25 and extends to the lower side of the connecting sleeve 231. A number of stirring paddles 42 are distributed in a circular shape on the outside of the rotating drum 41 and are fixedly connected to the rotating drum 41. The lower end of the rotating drum 41 located in the sealing cover 25 is fixedly connected to a driven gear 43, and a transmission rod 44 is rotatably mounted in the transmission groove 212. The transmission rod 44 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. The lower end of the transmission rod 44 is fixedly connected to a transmission bevel gear 46, and the transmission bevel gear 46 is located on the lower side of the docking joint 22.

[0038] When the device is powered on, the transmission bevel gear 46 drives the transmission rod 44 to drive the transmission gear 45 to rotate, and the rotating transmission gear 45 drives the driven gear 43 to rotate through the rack, so that the driven gear 43 drives the rotating drum 41 to drive the stirring paddle 42 to rotate in the medicine cup 201 to stir the medicine.

[0039] The difference from the above embodiment is that the stirring assembly 4 also includes a drive motor 47, which is fixedly installed in the shell 1 and is located on the side of the docking joint 22 away from the atomization assembly 5. A drive bevel gear 48 is coaxially fixedly connected to the output shaft of the drive motor 47, and the drive bevel gear 48 is meshed with the transmission bevel gear 46.

[0040] When the device is powered on, the driving motor 47 drives the transmission bevel gear 46 to rotate via the driving bevel gear 48 .

[0041] The difference from the above embodiment is that a docking port 11 is provided on the upper side of the housing 1 , a docking head 22 is installed in the docking port 11 by means of threads, and a connecting port 12 is fixedly installed on one side of the handle of the housing 1 .

[0042] When used in conjunction with a ventilator, the air supply pipe of the ventilator is connected to the connecting port 12 .

[0043] The difference from the above embodiment is that the atomizing head 51 is fixedly connected to the end of the shell 1, and an atomizing chamber 511 is opened in the atomizing head 51. A vibrating mesh 52 is fixedly installed in the end of the atomizing chamber 511 close to the medicine cup 201, and a piezoelectric transducer 53 is fixedly connected to the bottom of the vibrating mesh 52 close to the medicine cup 201. One end of the infusion pipe 54 is connected to the vibrating mesh 52, and the other end of the infusion pipe 54 is fixedly connected to a pipe joint 55, which corresponds to the docking groove 221, and a top block 56 is fixedly installed in the pipe joint 55.

[0044] Among them, when the docking joint 22 of the medicine cup 201 is docked with the docking port 11, the pipe joint 55 will be inserted into the docking groove 221, and the top block 56 on the pipe joint 55 will push up the sealing plug 311, thereby initially opening the liquid outlet 2111. When the medicine cup 201 is separated from the infusion pipe 54, the pipe joint 55 is pulled out of 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 52 to generate high-frequency mechanical vibration under the action of the current, thereby atomizing the medicine delivered from the infusion pipe 54 into small droplets that enter the atomization chamber 511, are sprayed out from the atomization head 51, and are inhaled by the patient.

[0045] The difference from the above embodiment is that the connecting port 12 is fixedly connected to one end of the gas pipeline 6, and the other end of the gas pipeline 6 is fixedly connected to the atomizing head 51, communicates with the atomizing chamber 511, and is located on the side of the vibrating mesh 52 away from the medicine cup 201.

[0046] After the connection port 12 is connected to the air supply pipe of the ventilator, the oxygen output by the ventilator enters the atomization chamber 511 through the air supply pipe 6, mixes with the medicine atomized by the vibrating mesh 52, and the atomized medicine is inhaled by the patient.

[0047] Embodiment 2:

[0048] The difference from the above embodiment is that an oronasal mask 7 is fixedly connected to the end of the atomizing head 51 away from the housing 1 .

[0049] Among them, when the patient undergoes aerosol treatment, wearing the oral and nasal mask 7 can facilitate the patient's inhalation.

[0050] Working principle: When in use, first connect the air supply pipe of the ventilator to the connecting port 12, and the oxygen output by the ventilator enters the atomization chamber 511 through the air supply pipe 6, and the transparent medicine cup 201 containing the medicine is installed on the shell 1, and then the power is turned on to perform the atomization of the medicine. When the medicine cup 201 is connected to the infusion pipe 54, the pipe joint 55 will be inserted into the docking groove 221, and the top block 56 on the pipe joint 55 will push up the sealing plug 311, so that the liquid outlet 2111 is opened a little bit, and the liquid outlet 2111 delivers the medicine in the medicine cup 201 to the atomization head 51 at a minimum flow rate for atomization. In this process, the piezoelectric transducer 53 drives the vibrating mesh 52 to generate high-frequency mechanical vibration under the action of the current, thereby 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 body by the patient along with the oxygen. At this time, the medicine content in the oxygen is at the minimum state, and at the same time, When the medicine content in the oxygen needs to be increased, 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 pressure 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, thereby increasing the content of the medicine in the oxygen. When the medicine content carried by the oxygen matches the patient, the knob 24 is stopped from being rotated. 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 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.

[0051] During the atomization process, as the device is powered on, the drive motor 47 drives the drum 41 to rotate through the transmission rod 44, so that the drum 41 drives the stirring paddle 42 to stir the medicine in the medicine cup 201, thereby preventing the medicine from settling in the medicine cup 201 during the atomization process and remaining in the device, so that the medicine can fully play its role. After the treatment is completed, the device is turned off to end the atomization work, the stirring component 4 stops running, and the medicine cup 201 is removed and the used medicine cup 201 is disinfected and cleaned. In this process, the forward rotation is not performed. Turning the knob 24 will close the liquid outlet 2111, making the liquid outlet 2111 in an open state, which is convenient for medical staff to clean. After completing the cleaning and drying the medicine cup 201, turn the knob 24 forward again, so that the push rod 31 drives the sealing plug 311 downward with the cooperation of the thread. After the thread of the push rod 31 disengages from the thread of the connecting sleeve 231, the compressed pressure spring 32 pushes the sealing plug 311 to contact the bottom of the regulating chamber 211, thereby completely closing the liquid outlet 2111 and disconnecting it from the knob 24, waiting for the next use.
