Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] The nebulizer device for endotracheal intubation disclosed in the present invention is mainly used in scenarios where a general nebulizer cannot evenly mix oxygen and anesthetic drugs, causing physical discomfort to the patient during surgery, reducing the safety of the surgery, and also affecting the patient's personal safety.

[0035] An auxiliary mechanism is installed on the medicine bottle 4, which facilitates subsequent operations on the atomized medicine;

[0036] An oxygen connection mechanism is installed at the bottom of the housing 1 near the air inlet pipe 14, and the oxygen connection mechanism is used to connect oxygen;

[0037] A support structure is installed at the bottom of the housing 1, and the support structure is used to reduce vibration;

[0038] A safety mechanism is installed on the top of the housing 1, and the safety mechanism is used to recover the medicine.

[0039] The directions of the air jet holes 13 are all counterclockwise, the anode wire 21 and the cathode wire 23 are electrically connected to the transducer sheet 22 respectively, the fiber block 16 and the fiber rod 17 are both made of fiber material and have water absorption properties, and the sliding block 18 slides inside the connecting tube 5.

[0040] In this embodiment, the pre-mixed medicine is in the state of a solution. The medicine is absorbed into the fiber rod 17 through the adsorption effect of the fiber rod 17. The fiber attracts the liquid and the surface tension of the liquid, and the medicine is guided into the fiber block 16. The sliding block 18 is driven to slide up and down by rotating the threaded rod 19, thereby driving the fiber block 16 to move up and down. By adjusting the gap between the fiber block 16 and the connecting tube 5, the upward flow speed of the drug solution can be controlled, thereby controlling the flow rate of the drug.

[0041] Furthermore, the drug contacts the transducer plate 22 through the connecting hole 15, and positive and negative electricity are respectively applied to the anode line 21 and the cathode line 23 to control the regular change of voltage. Since the material of the transducer plate 22 is a piezoelectric ceramic plate, a center hole is arranged at the center of the transducer plate 22, and the transducer plate 22 can convert the voltage into mechanical vibration. The drug in contact with the transducer plate 22 in the connecting hole 15 is vibrated into mist droplets through the up and down vibration of the transducer plate 22, and is discharged through the center hole. The atomized drug enters the housing 1 through the connecting tube 5, and oxygen enters the jet ring 9 through the air inlet pipe 14. Due to the design of multiple jet holes 13, and the directions of the jet holes 13 are all counterclockwise, oxygen is ejected through the jet holes 13, causing the mixing wheel 12 to rotate counterclockwise, so that the oxygen and the atomized drug are evenly mixed, and the drug concentration is prevented from being too concentrated, which may cause irritation to the patient's lungs after inhalation, thereby achieving the effect of evenly mixing the oxygen and the atomized drug.

[0042] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6 In a preferred embodiment, the auxiliary mechanism includes a filling pipe 37 arranged on the top of the medicine bottle 4, one end of the filling pipe 37 is threadedly connected to a safety cover 36, a drain pipe 33 is arranged at the bottom of the medicine bottle 4, the bottom of the drain pipe 33 is threadedly connected to a drain cover 34, and a baffle plate 38 is fixedly connected to the upper surface of the fiber rod 17, and a plurality of guide plates 35 are arranged on the upper surface of the baffle plate 38.

[0044] The function of the filling tube 37 is to inject medicine, the function of the baffle plate 38 is to shield the medicine injected by the filling tube 37 to prevent the medicine from directly contacting the fiber rod 17 and preventing the drug concentration inside the fiber rod 17 from being too high, the function of the guide plate 35 is to guide the medicine so that the medicine flows into the bottom of the medicine bottle 4, and the function of the guide fiber 32 is to absorb the diluted medicine at the bottom into the fiber rod 17 when the drug liquid level is too low.

[0045] In this embodiment, during the mixing process, part of the atomized medicine will contact the inner wall of the device, resulting in the accumulation of drug droplets on the inner wall of the device. The drug solution that has accumulated from small amounts will flow into the recovery tube 3, and the medicine in the recovery tube 3 will flow back to the medicine bottle 4 through the reflux tube 11, thereby recovering the medicine and reducing the waste of the medicine. If new medicine needs to be added during the process, the provider can provide a patient safety cover 36 and inject the new medicine through the filling tube 37, which can facilitate the addition of new medicine. After use, if there is any medicine residue, the remaining medicine can be discharged through the drain pipe 33 by rotating the drain cover 34, thereby cleaning the medicine bottle 4.

[0046] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6 In a preferred embodiment, the oxygen connecting mechanism includes an oxygen tube 2 fixedly connected to the bottom of the shell 1 at the position of the air inlet pipe 14, a plug rod 29 is slidably connected to the inside of the oxygen tube 2, one end of the plug rod 29 is fixedly connected to a sealed piston 31, a sealing groove 30 is provided at the bottom edge of the sealed piston 31, the other end of the plug rod 29 is fixedly connected to a contact block 28, a return spring 25 is sleeved on the other end of the plug rod 29 near the contact block 28, a connector 27 is threadedly connected to the bottom of the oxygen tube 2 near the plug rod 29, an excitation end 26 is designed on the top of the connector 27, and a plurality of connecting holes 24 are provided inside the oxygen tube 2.

[0047] In this embodiment, when oxygen needs to be connected, the oxygen tube 2 is connected to the connector 27, and the connector 27 is connected to the oxygen tube 2. The excitation end 26 at the top of the connector 27 squeezes the contact block 28, driving the insertion rod 29 and the closed piston 31 to slide, so that the sealing groove 30 at the bottom edge of the closed piston 31 is separated from the inner wall of the oxygen tube 2, thereby connecting the two ends of the oxygen tube 2, preventing oxygen from overflowing when the two ends of the oxygen tube 2 are not connected, thereby causing oxygen leakage and reducing oxygen waste.

[0048] Reference Figure 1 , Figure 2 , Figure 3 and Figure 8 In a preferred embodiment, the support structure includes two first connecting plates 44 fixedly connected to the bottom of the shell 1, one side of the first connecting plate 44 is rotatably connected to the first support frame 10, and the two sides of the bottom end of the first support frame 10 are respectively fixedly connected to second connecting plates 45, and one side of the second connecting plate 45 is rotatably connected to the second support frame 46.

[0049] In this embodiment, the second support frame 46 is supported at the patient's shoulder position, and a torsion spring is provided at the connection between the second connecting plate 45 and the second support frame 46. During the patient's breathing, the rise and fall of the shoulders drives the relative rotation of the second support frame 46 and the second connecting plate 45. Due to the action of the torsion spring, the shaking of the shell 1 caused by the rise and fall of the shoulders can be buffered, so that the shell 1 on the top of the first connecting plate 44 can remain stable.

[0050] Reference Figure 1 , Figure 2 , Figure 3 and Figure 7 In a preferred embodiment, the safety mechanism includes a conduit 6 plugged into the top of the outer shell 1, the other end of the conduit 6 is sleeved with a collecting tube 7, a guide tube 40 is designed inside the collecting tube 7, a guide tube 43 is provided inside the collecting tube 7 at the bottom of the guide tube 40, and a liquid outlet pipe 41 is designed inside the collecting tube 7 at the bottom of the guide tube 43.

[0051] An absorption tube 8 is inserted into the bottom of the collecting tube 7 near the liquid outlet pipe 41 . An absorption sponge 42 is provided at the bottom of the inner wall of the absorption tube 8 . A joint 39 is inserted into one end of the guide tube 40 .

[0052] The two ends of the guide tube 43 are respectively connected to the guide tube 40, the liquid outlet pipe 41 is connected to the bottom of the guide tube 43, and the liquid outlet pipe 41 is connected to the inside of the absorption tube 8. The function of the absorption sponge 42 is to absorb the medicine in the absorption tube 8 to prevent the volatilization of the medicine from affecting the absorption of the medicine.

[0053] In this embodiment, the atomized medicine mixed with oxygen enters the guide tube 40 inside the collecting tube 7 through the catheter 6, and enters the intubation tube of the patient's trachea through the guide tube 40 and the joint 39, so that the patient breathes and absorbs the medicine through the lungs. Since the pipeline paths of the catheter 6 and the guide tube 40 are relatively long, part of the medicine will contact the inner walls of the pipelines of the catheter 6 and the guide tube 40 and gather into droplets. The droplets flow downward and are collected together by the guide tube 43. The collected drug droplets are collected into the absorption tube 8 through the liquid outlet pipe 41 to prevent the gathered droplets from entering the patient's lungs and causing discomfort to the patient, thereby protecting the patient. The absorption sponge 42 absorbs the medicine and prevents the medicine from volatilizing and affecting the treatment effect.

[0054] Working principle: When in use, the pre-mixed medicine is poured into the medicine bottle 4 through the filling tube 37. The medicine is in the state of solution. The medicine is absorbed into the fiber rod 17 through the adsorption effect of the fiber rod 17. The fiber attracts the liquid and the surface tension of the liquid, and the medicine is guided into the fiber block 16. The sliding block 18 is driven to slide up and down by rotating the threaded rod 19, thereby driving the fiber block 16 to move up and down. By adjusting the gap between the fiber block 16 and the connecting tube 5, the upward flow speed of the medicine solution can be controlled, thereby controlling the flow rate of the medicine. The medicine contacts the transducer 22 through the connecting hole 15, and the positive and negative electricity are respectively applied to the anode line 21 and the cathode line 23 to control the regular change of the voltage. The material of 22 is a piezoelectric ceramic plate, and a center hole is set in the center of the transducer plate 22. The transducer plate 22 can convert voltage into mechanical vibration. The medicine in contact with the transducer plate 22 in the connecting hole 15 is vibrated into mist droplets through the up and down vibration of the transducer plate 22, and discharged through the center hole. The atomized medicine enters the housing 1 through the connecting pipe 5, and the oxygen enters the jet ring 9 through the air inlet pipe 14. Due to the design of multiple jet holes 13, and the orientation of the jet holes 13 is counterclockwise, oxygen is ejected through the jet holes 13, so that the mixing wheel 12 rotates counterclockwise, and the oxygen and the atomized medicine are evenly mixed, so as to prevent the concentration of the medicine from being too concentrated, which will cause irritation to the patient's lungs after inhalation, and the effect of evenly mixing the oxygen and the atomized medicine is achieved. During the process, part of the atomized medicine will contact the inner wall of the device, resulting in the accumulation of drug droplets on the inner wall of the device. The drug solution that has accumulated from small amounts will flow into the recovery tube 3, and the medicine in the recovery tube 3 will flow back to the medicine bottle 4 through the reflux tube 11, which has the effect of recovering the medicine and reducing the waste of the medicine. If new medicine needs to be added during the process, the provider can provide a patient safety cover 36 and inject the new medicine through the filling tube 37, which can facilitate the addition of new medicine. After use, if there is any drug residue, the remaining drug can be discharged through the drain pipe 33 by rotating the drain cover 34, which has the effect of cleaning the medicine bottle 4. When oxygen needs to be connected, connect the oxygen tube 2 to the connector 27, connect the connector 27 to the oxygen tube 2, and connect the connector 27 to the oxygen tube 2. The exciting end 26 at the top of 27 squeezes the contact block 28, driving the insertion rod 29 and the sealed piston 31 to slide, so that the sealing groove 30 at the bottom edge of the sealed piston 31 is separated from the inner wall of the oxygen tube 2, which has the effect of connecting the two ends of the oxygen tube 2, preventing oxygen from overflowing when the two ends of the oxygen tube 2 are not connected, thereby causing oxygen leakage, reducing oxygen waste, by supporting the second support frame 46 at the patient's shoulder position, the second connecting plate 45 and the second support frame 46 are connected. A torsion spring is provided at the connection between the second supporting frame 46 and the second connecting plate 45. During the patient's breathing process, the ups and downs of the shoulders drive the relative rotation of the second supporting frame 46 and the second connecting plate 45. Due to the action of the torsion spring, the shaking of the shell 1 caused by the ups and downs of the shoulders can be buffered, so that the shell 1 at the top of the first connecting plate 44 remains stable.The atomized medicine mixed with oxygen enters the guide tube 40 inside the collection tube 7 through the conduit 6, and enters the cannula of the patient's trachea through the guide tube 40 and the joint 39, so that the patient can breathe and absorb the medicine through the lungs. Since the pipeline paths of the conduit 6 and the guide tube 40 are long, some of the medicine will contact the inner walls of the conduit 6 and the guide tube 40 and gather into droplets. The droplets flow downward and are collected together by the guide tube 43. The collected drug droplets are collected into the absorption tube 8 through the liquid outlet pipe 41 to prevent the accumulated droplets from entering the patient's lungs and causing discomfort to the patient, thereby protecting the patient. The absorption sponge 42 absorbs the medicine to prevent the medicine from volatilizing and affecting the treatment effect.
