Description

Technical Field

[0001] The present invention relates to the technical field of medical care equipment, and in particular to an anesthetic atomizing device for anesthesia in an operating room. Background Art

[0002] Atomization refers to the process of dispersing liquid into tiny droplets through a nozzle or high-speed airflow. The numerous dispersed droplets atomized can capture particulate matter in the gas. There are several methods of liquid atomization, including pressure atomization, rotary disk atomization, gas atomization, and sonic atomization. It means that the liquid is transformed into small droplets through a special device and sprayed out in a mist form, so that the liquid is atomized into small molecular aerosols, which makes it easier for drug molecules to directly enter the capillaries or alveoli through the aerosols to achieve therapeutic effects.

[0003] The Chinese patent with the announcement number CN112587763B discloses an anesthetic atomization device for anesthesiologists in operating rooms, including an atomization tube, the outer side of the atomization tube is fixedly connected to a first motion chamber, the inner side of the first motion chamber is connected to a second motion chamber, the inner side of the second motion chamber is provided with a first coil, the inner side of the second motion chamber and the upper side of the first coil are connected to a first magnetic rod, the upper side of the first magnetic rod is connected to a heating rod, the left and right sides of the first magnetic rod are both rotatably connected to a first connecting rod, the upper side of the first connecting rod is rotatably connected to a first rotating rod, the upper side of the first rotating rod is slidably connected to a first rotating plate, and a tripod is provided on the left side of the first rotating plate. In the anesthetic atomization device for anesthesiologists in operating rooms, the first coil generates a magnetic force that repels the first magnetic rod, thereby driving the heating rod to extend inward, thereby heating the anesthetic mist. This structure achieves the effect of heating the liquid medicine and alleviating the pain of the patient.

[0004] However, the anesthetic atomizer device used by anesthesiologists in the operating room in the above patent cannot adjust the flow rate of the atomized gas discharged through the exhaust pipe during use, so it is not convenient for the device to adapt to the breathing frequency of different patients.

[0034] The following will be combined with the attached embodiment of the present invention Figure 1-Figure 14 , the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In order to adjust the flow rate of the atomized gas discharged from the exhaust pipe 5, so as to adapt its use to the breathing frequency of different patients, thereby preventing the atomized gas from hitting the nasal cavity when the patient inhales, an anesthetic atomizer device for anesthesia in an operating room provided in this embodiment is provided. Figure 1-Figure 14 It includes an atomizer shell 1 with a handle, a filter mechanism 2 arranged on the atomizer shell 1, and a storage groove 3 opened on the atomizer shell 1. A transparent liquid medicine tank 4 is fixedly installed inside the storage groove 3. An exhaust pipe 5 is fixedly connected to the upper surface of the transparent liquid medicine tank 4. An adjustment mechanism 6 is arranged on the outer surface of the lower end of the exhaust pipe 5. At the same time, the upper end of the exhaust pipe 5 is connected to a connecting pipe 8 through a connecting mechanism 7.

[0036] like Figure 1 as well as Figure 7 As shown, in order to facilitate pouring the anesthetic into the transparent medicine liquid tank 4, an inlet pipe 41 is fixedly connected to the upper surface of the transparent medicine liquid tank 4, and a cap 42 is threadedly sleeved on the outer surface of one end of the inlet pipe 41 located outside the transparent medicine liquid tank 4. The anesthetic is poured into the transparent medicine liquid tank 4 through the inlet pipe 41, and the inlet pipe 41 is opened or closed by threading the inner thread of the cap 42 with the outer thread of the inlet pipe 41 to prevent dust and air from entering the transparent medicine liquid tank 4 through the inlet pipe 41 when not in use.

[0037] like Figure 1 as well as Fig.14 As shown, in order to facilitate observation of the situation in the transparent liquid medicine tank 4 at any time, a glass window 9 is provided on one side of the atomizing housing 1 , and the glass window 9 is used to observe the situation in the transparent liquid medicine tank 4 .

[0038] like Figure 8 As shown, in order to atomize the anesthetic in the transparent medicine liquid tank 4, a mounting column 10 is fixedly installed on the inner top wall of the transparent medicine liquid tank 4, and two atomizing sheets 11 are fixedly sleeved on the outer surface of the mounting column 10. The two atomizing sheets 11 are connected to the ultrasonic vibration component in the atomizing shell 1 through a wire. The ultrasonic vibration component in the atomizing shell 1 transmits an electrical signal to the atomizing sheet 11, causing the atomizing sheet 11 to generate high-frequency vibration. At the same time, a water level sensor 12 is fixedly installed on the inner wall of the transparent medicine liquid tank 4, and the lowest end of the water level sensor 12 is located at the upper end of the atomizing sheet 11 above. When the water level in the transparent medicine liquid tank 4 is lower than the atomizing sheet 11, the water level sensor 12 stops the ultrasonic vibration component and the atomizing sheet 11 in the atomizing shell 1, thereby avoiding damage to the atomizing sheet 11.

[0039] like Figure 1 As shown, in order to start the entire device, a power switch 13, a timer knob 14, an atomization amount adjustment knob 15 and a control button 16 are sequentially arranged on one side of the outer surface of the atomizing shell 1. The power switch 13 is used to control the on and off of the filtering mechanism 2, the ultrasonic vibration component in the atomizing shell 1 and the atomizing sheet 11. The control button 16 is used to control the opening or closing of the adjustment mechanism 6. The electrical control end of the timer knob 14 is electrically connected to the electrical control output end of the ultrasonic vibration component in the atomizing shell 1 through a control line, and the timer knob 14 is used to control the use time of the ultrasonic vibration component in the atomizing shell 1. The electrical control end of the atomization amount adjustment knob 15 is electrically connected to the electrical control output end of the atomizing sheet 11 through a control line, and is used to control the frequency of the high-frequency resonance of the atomizing sheet 11. The entire device is turned on by the power switch 13, and the running time of the entire device is controlled by the timer knob 14. The ultrasonic vibration component in the atomizing shell 1 transmits an electrical signal to the atomizing sheet 11, prompting the atomizing sheet 11 to generate high-frequency vibration.

[0040] like Figure 1-Figure 4 as well as Figure 7-Figure 8 As shown, in order to facilitate the introduction of air into the transparent medicine liquid tank 4, a mounting shell 17 is fixedly installed on one side of the upper surface of the atomizing shell 1, a fan 18 is installed inside the mounting shell 17, and an air inlet pipe 19 is fixedly connected to one side of the mounting shell 17. One end of the exhaust pipe 5 extends into the transparent medicine liquid tank 4 and passes through the lower surface of the mounting column 10. The power switch 13 is turned on to start the fan 18. The rotation of the fan blades drives the air to enter the transparent medicine liquid tank 4 along the air inlet pipe 19. The vibration of the atomizing sheet 11 dissolves the air entering through the air inlet pipe 19 in the anesthetic, and forms atomized gas that is discharged from the air outlet pipe.

[0041] Among them, Figure 1-Figure 6 As shown, the filtering mechanism 2 is used to filter the air entering the transparent medicine liquid tank 4.

[0042] In order to filter the air sucked in by the fan 18, the filtering mechanism 2 includes a filtering housing 21 fixedly connected to the upper surface of the mounting housing 17. The upper surface of the filtering housing 21 is provided with air inlet holes 22 in a circular array. A card slot 23 is provided on the surface of the filtering housing 21. A card plate 24 is slidably connected to the inner wall of the card slot 23. A filter element 25 is provided on the inner wall of the card plate 24. The power switch 13 is turned on to start the fan 18. The rotation of the fan blades drives the air into the filtering housing 21 from the air inlet hole 22 on the filtering housing 21, enters the mounting housing 17 after being filtered by the filter element 25 on the card plate 24, and enters the transparent medicine tank 4 along the air inlet pipe 19.

[0043] In order to facilitate the disassembly and assembly of the filter element 25, a plurality of hooks 26 are fixedly installed under the inner wall of the clamping plate 24. The hooks are used to support and clamp the filter element 25, and make the filter element 25 clamped with the hooks 26 under the action of its own gravity. When replacement is needed, the filter element 25 is pushed upward from the bottom to disengage the filter element 25 from the hooks 26, and then the filter element 25 is removed.

[0044] Among them, Figure 8-Figure 11 As shown, the regulating mechanism 6 is used to adjust the flow rate of the atomizing gas discharged through the exhaust pipe 5.

[0045] In order to drive the adjustment mechanism 6, the adjustment mechanism 6 includes a servo motor 601 fixedly mounted on the transparent medicine liquid tank 4, one end of the output shaft of the servo motor 601 passes through the transparent medicine liquid tank 4 and is fixedly sleeved with a rotating shaft 602, the upper end of the rotating shaft 602 is mounted on the inner top wall of the transparent medicine liquid tank 4 through a bearing, and the lower end of the rotating shaft 602 is fixedly sleeved with a gear 603, and at the same time, the lower end of the exhaust pipe 5 is fixedly connected with a mounting block 604, the upper surface of the mounting block 604 is fixedly connected to the inner top wall of the transparent medicine liquid tank 4, the interior of the mounting block 604 is fixedly connected with a connecting block 605, and the interior of the connecting block 605 is provided with a gear ring 606, the surface of the gear 603 is meshed with the surface of the gear ring 606, and the control button 16 is turned on as needed to start the servo motor 601, the rotation of the output shaft of the servo motor 601 drives the rotating shaft 602 to rotate, the rotation of the rotating shaft 602 drives the gear 603 to rotate, and the rotation of the gear 603 drives the gear ring 606 meshed with it to rotate along the inner wall of the connecting block 605.

[0046] In order to adjust the aperture size of the exhaust pipe 5, thereby adjusting the flow rate of the atomized gas, a track groove 607 is opened on the surface of the toothed ring 606, and six special-shaped blocks 608 are slidably engaged with the inner wall of the track groove 607, and the surface of the special-shaped block 608 is fixedly connected with a rubber pad 611, and at the same time, a guide column 609 is fixedly connected to the upper surface of the special-shaped block 608, and a slide groove 610 is penetrated through the upper surface of the connecting block 605, and the surface of the guide column 609 is slidably engaged with the inner wall of the slide groove 610. The rotation of the toothed ring 606 drives the track groove 607 to move, and the movement of the track groove 607 drives the special-shaped block 608 to move. The movement of the special-shaped block 608 causes it to move along the inner wall of the slide groove 610, thereby driving the special-shaped blocks 608 to gather or separate from each other.

[0047] Among them, Fig. 9 as well as Figure 12-13 As shown, the connecting mechanism 7 is used to connect the connecting pipe 8 to the exhaust pipe 5 .

[0048] In order to prevent the connection between the connecting pipe 8 and the exhaust pipe 5 from causing leakage of atomized gas, the connecting mechanism 7 includes connecting rings 71 fixedly sleeved on the exhaust pipe 5 and the connecting pipe 8 respectively, and a sealing gasket is arranged between the two connecting rings 71. The outer surfaces of the two connecting rings 71 are both provided with elastic ropes 72 distributed in a circular array, and one end of the elastic rope 72 is fixedly connected with a buckle 73. The outer surfaces of the exhaust pipe 5 and the connecting pipe 8 are also provided with buckles 74 distributed in a circular array. The buckles 73 and the buckles 74 are sleeved with each other. The buckle 73 is sleeved with the buckle 74 by pulling the elastic rope 72, thereby fixing the two connecting rings 71 together, and sealing the gap between the two connecting rings 71 by sealing the gasket.

[0049] Among them, Figure 8 as well as Fig.14As shown, in order to prevent the anesthetic agent in the transparent medicine liquid tank 4 from being wasted if the level is below the water level sensor 12, a pushing cylinder 101 is fixedly installed inside the atomizing shell 1, and one end of the piston rod of the pushing cylinder 101 extends into the transparent medicine liquid tank 4 and is fixedly connected with a piston 102. By extending the piston rod of the pushing cylinder 101, the piston 102 moves upward along the inner wall of the transparent medicine liquid tank 4, and the water level of the anesthetic agent rises as the piston 102 moves upward.

[0050] Working principle: Please refer to Figure 1-Figure 14 As shown, when in use, the cap 42 is rotated to open, and the anesthetic is poured into the transparent liquid medicine tank 4 through the liquid inlet pipe 41, ensuring that the anesthetic covers the atomizing sheet 11 but does not fill the entire transparent liquid medicine tank 4, and then the cap 42 is aligned with the liquid inlet pipe 41, and the cap 42 is rotated in the opposite direction to close the liquid inlet pipe 41; Then align the connecting tube 8 with the connecting ring 71 on the liquid inlet tube 41, pull the elastic rope 72 on the connecting ring 71 to make the buckle 73 and the buckle 74 fit together, and then fix the two connecting rings 71 together, and seal the gap between the two connecting rings 71 with a sealing gasket; Then, the timer knob 14 is used to determine the time for the entire device to run, and the vibration frequency of the two atomizing sheets 11 is controlled by the atomization amount adjustment knob 15, and then the power switch 13 is turned on; The power switch 13 is turned on to start the fan 18 in the installation housing 17. The rotation of the fan blades drives the air to enter the filter housing 21 from the air inlet 22 on the filter housing 21, and then enter the installation housing 17 after being filtered by the filter element 25 on the card plate 24, and enter the installation column 10 along the air inlet pipe 19, and enter the transparent liquid medicine tank 4 from the lower end of the installation column 10; At the same time, the opening of the source switch starts the ultrasonic vibration component in the atomizing housing 1 to transmit an electrical signal to the atomizing sheet 11, causing the atomizing sheet 11 to generate high-frequency vibrations and dissolve the incoming air in the anesthetic to form atomized gas that is discharged from the exhaust pipe 5. The situation in the transparent liquid medicine tank 4 and the air flow speed can be conveniently observed through the glass window 9 on one side; The flow rate of the atomized gas discharged from the exhaust pipe 5 needs to be adjusted. The control button 16 is turned on to start the servo motor 601. The rotation of the output shaft of the servo motor 601 drives the rotating shaft 602 to rotate. The rotation of the rotating shaft 602 drives the gear 603 to rotate. The rotation of the gear 603 drives the gear ring 606 meshing therewith to rotate along the inner wall of the connecting block 605. The rotation of the gear ring 606 drives the track groove 607 to move. The movement of the track groove 607 drives the special-shaped block 608 to move. The movement of the special-shaped block 608 causes it to move along the inner wall of the slide groove 610, thereby driving the special-shaped blocks 608 to gather or separate from each other, thereby adjusting the aperture size of the exhaust pipe 5. When the water level in the transparent liquid medicine tank 4 is lower than the atomizing sheet 11, the water level sensor 12 stops the operation of the ultrasonic vibration assembly and the atomizing sheet 11 in the atomizing housing 1, thereby preventing the atomizing sheet 11 from being damaged. At the same time, the cap 42 is rotated and removed, and the pushing cylinder 101 is started to push the piston rod of the cylinder 101 to extend and move the piston 102 upward along the inner wall of the transparent liquid medicine tank 4, thereby driving the water level of the anesthetic to rise, thereby preventing most of the anesthetic at the bottom from being wasted; When the filter element 25 needs to be replaced, the clamping plate 24 is pulled out of the clamping slot 23 , and the filter element 25 on the clamping plate 24 is pushed upward from the bottom to disengage the filter element 25 from the clamping hook 26 , and then the filter element 25 is removed.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
