By heating the mask, the inner wall of the mask does not generate water mist due to too large temperature difference with air exhaled by a user, and by continuously blowing air to the outside of the mask, an'air curtain wall 'is formed outside the mask by means of blown air flow, so that external cold air is prevented from being in contact with the mask, and the air quality is improved. Therefore, cold air is prevented from making contact with the heated mask to form water mist outside the mask, finally it can be guaranteed that water mist cannot be generated on the inner side and the outer side of the mask when the mask is used, and a doctor can conveniently observe the breathing state of a patient through the mask. When not in use, the pipe orifice of the guide pipe used for blowing out airflow can be sealed, so that external fine dust is prevented from entering the guide pipe, and the normal airflow spraying is influenced due to the fact that the guide pipe is blocked for a long time.

[0002] An anesthesia nebulizer is a medical device used to convert anesthetic drugs into tiny droplets or particles, which are delivered to patients through the respiratory tract to achieve local or general anesthesia. In some minor surgeries in the oral cavity, ears, nose and throat, etc., local anesthesia can be performed through an anesthesia nebulizer, which can anesthetize the nerve endings in the surgical area, achieve analgesic effect, and facilitate the doctor's operation.

[0003] When using an existing anesthesia nebulizer, a mask is placed on the patient's face, and the nebulizer is used to pass atomized anesthetic into the mask to anesthetize the patient. However, when in use, the temperature of the mask is lower than the temperature of the patient's exhaled gas.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0026] The present invention provides an anesthetic atomizer for medical treatment, such as Figures 1 to 7 As shown, it includes an atomizer 1, one end of the atomizer 1 is connected to a joint pipe 2 that matches it, one end of the joint pipe 2 is connected to a mask 3, the interior of the mask 3 is provided with a cavity 21, the exterior of the mask 3 is provided with a bracket 4, the bracket 4 is connected to the joint pipe 2 through a connecting component, a rubber belt 5 is rotatably installed inside the bracket 4, the interior of the rubber belt 5 is provided with a cavity, the exterior of the rubber belt 5 is equidistantly surrounded by a conduit 6 communicating with the cavity, the exterior of the rubber belt 5 is provided with a driving component for driving the rotation thereof, the exterior of the mask 3 is fixedly connected with an output pipe 8 communicating with the cavity 21, a notch is provided on the inner side of the bracket 4, a connecting pipe 7 communicating with the internal cavity of the rubber belt 5 is provided in the notch, one end of the output pipe 8 is connected in the connecting pipe 7, the exterior of the mask 3 is fixedly connected with an input pipe 9 communicating with the cavity 21, and an end of the input pipe 9 away from the mask 3 is provided with an inlet component for introducing hot air flow into the interior thereof.

[0027] When in use, the mask 3 is worn on the patient's face, and the atomized anesthetic is continuously input into the mask 3 through the nebulizer 1 in cooperation with the joint tube 2 to anesthetize the patient. A warm air flow is continuously input into the cavity 21 of the mask 3 through the input assembly in cooperation with the input tube 9, so that the mask 3 is heated, and the temperature inside the mask 3 is close to the temperature of the gas exhaled by the user, so that the temperature of the inner wall of the mask 3 will not be lower than the temperature of the gas exhaled by the user, thereby ensuring that water mist will not be generated on the inner wall of the mask 3. The continuously introduced warm air flow enters the cavity of the rubber belt 5 through the output tube 8 and the connecting tube 7, and then fills the cavity and is blown to the outside of the mask 3 through the conduit 6. The rubber belt 5 is driven to rotate in the forward and reverse directions by the driving assembly, so that the connecting tube 7 rotates accordingly, so that the air blown out The warm air flow can blow toward the mask 3 more comprehensively, so as to blow away the external cold air, keep the cold air away from the outside of the mask 3, and avoid the contact of the cold air with the heated outer side of the mask 3, thereby avoiding the generation of water mist on the outside of the mask 3. During the whole process, by heating the mask 3, the inner wall of the mask 3 will not generate water mist due to the large temperature difference between the mask 3 and the gas exhaled by the user. By continuously blowing air outside the mask 3, an "air curtain wall" is formed outside the mask 3 by relying on the blown air flow, so as to avoid the external cold air from contacting the mask 3, thereby avoiding the contact of the cold air with the heated mask 3 to form water mist outside the mask 3. Finally, it can be ensured that no water mist is generated on both the inner and outer sides of the mask 3 when in use, thereby facilitating the doctor to observe the patient's breathing status through the mask 3.

[0028] like Figure 2 As shown, the inlet assembly includes a heater 10 , the output end of the heater 10 is connected to a butt joint, and one end of the butt joint away from the heater 10 is threadedly connected to the inside of the inlet pipe 9 .

[0029] The heater 10 is a heater capable of adjusting the temperature of warm air in the prior art. By adjusting the temperature of the warm air flow output by the heater 10, the temperature of the warm air flow heated to the mask 3 can be close to the temperature of the air flow exhaled by the patient, thereby ensuring that the temperature of the mask 3 is close to that of the air flow exhaled by the patient.

[0030] like Figure 4 and Figure 6 As shown, the driving assembly includes teeth 11 equidistantly arranged on the outside of the rubber belt 5 , a motor 12 is fixedly mounted on the bracket 4 , and an output shaft of the motor 12 is fixedly connected to a gear 13 that matches the teeth 11 .

[0031] Start the motor 12 to make its output shaft rotate forward and reverse intermittently, so that the gear 13 rotates accordingly, and then cooperates with the teeth 11 to rotate the rubber belt 5 accordingly. The material of the bracket 4 is stainless steel, and the side of the bracket 4 that contacts the rubber belt 5 is smooth, and the rubber belt 5 can rotate along the bracket 4.

[0032] like Figure 5 to Figure 6As shown, the connecting assembly includes a pair of clamps 14, and a slide groove is symmetrically opened on the top of the bracket 4. The clamps 14 are slidably set in the slide groove. The sides of the two clamps 14 that are away from each other are fixedly connected to the inner wall of the slide groove through a spring 15. The pair of clamps 14 are clamped on the outside of the joint pipe 2.

[0033] The movement of pulling the pair of clamping plates 14 away from each other compresses the spring 15 to deform it. With the separation of the pair of clamping plates 14, the clamping of the joint pipe 2 is cancelled, and the bracket 4 can be separated from the joint pipe 2.

[0034] like Figure 5 to Figure 6 As shown, the outside of the bracket 4 is fixedly connected to a rectangular tube 19 through a connecting plate 16, a rectangular column 18 is slidably installed inside the rectangular tube 19, a screw rod 20 is rotatably installed on the top of the rectangular column 18, the screw rod 20 is threadedly connected to the top wall of the rectangular tube 19, the top of the screw rod 20 extends to the outside of the rectangular tube 19, an extrusion plate 17 is fixedly installed on the bottom of the rectangular column 18, and the conduit 6 is a rubber hose.

[0035] When not in use, the screw rod 20 is rotated forward to make it descend with the rectangular column 18, thereby bringing the squeezing plate 17 down. The squeezing plate 17 presses against the end of the conduit 6 to bend the end of the conduit 6 downward. As the squeezing plate 17 descends, the bracket 4 is used to squeeze multiple conduits 6. Finally, the end of the conduit 6 is located between the squeezing plate 17 and the bracket 4, and the pipe mouth of the conduit 6 is clamped and flattened, so that the pipe mouth of the conduit 6 is closed to prevent external fine dust from entering the conduit 6 and clogging the conduit 6 for a long time to affect its normal airflow. The screw rod 20 is reversed to make it rise with the rectangular column 18, and vice versa to achieve the reset of the squeezing plate 17, cancel the squeezing of the conduit 6, and the conduit 6 is reset under the support of its own toughness.

[0036] like Figure 3 As shown, the output pipe 8 is a corrugated hose, one end of which is fixedly connected to a pipeline, and the pipeline is threadedly connected in the connecting pipe 7.

[0037] The forward-rotating pipeline separates it from the connecting pipe 7, so that the mask 3 can be separated from the bracket 4 later. The output pipe 8 is a corrugated hose so that when the rubber belt 5 rotates, the output pipe 8 can adapt to the tensile deformation to meet the use requirements.

[0038] like Figure 7 As shown, the mask 3 is a transparent mask and the inlet tube 9 is a transparent hose.

[0039] This makes it easy for the doctor to observe the patient's breathing status through the mask 3. The input tube 9 is a transparent hose, which can avoid blocking the mask 3, making it easier for the doctor to observe the patient's breathing status.

[0040] like Figure 2As shown, when the conduit 6 is not squeezed, its own toughness can keep itself in a vertical state, and the tube mouth of the conduit 6 is inclined toward the mask 3.

[0041] This ensures that the airflows blown out of multiple ducts 6 can intersect, thereby forming an "air curtain wall" outside the mask 3, thereby preventing cold air from contacting the outside of the mask 3.

[0042] Working principle: When in use, the mask 3 is worn on the patient's face, and the atomized anesthetic is continuously input into the mask 3 through the atomizer 1 in cooperation with the joint tube 2 to anesthetize the patient. The heater 10 is started to cooperate with the docking tube and the input tube 9 to continuously input warm air flow into the cavity 21 of the mask 3, so that the mask 3 is heated, so that the temperature inside the mask 3 is close to the temperature of the gas exhaled by the user, and the temperature of the inner wall of the mask 3 is not lower than the temperature of the gas exhaled by the user, thereby ensuring that water mist is not generated on the inner wall of the mask 3. The continuously introduced warm air flow enters the rubber belt through the output tube 8 and the connecting tube 7. 5, and then the cavity is filled and blown to the outside of the mask 3 through the conduit 6, and the motor 12 is started to make its output shaft intermittently rotate forward and reverse, so that the gear 13 rotates accordingly, and then cooperates with the teeth 11 to rotate the rubber belt 5 accordingly, so that the forward and reverse switching rotation of the rubber belt 5 makes the connecting tube 7 rotate accordingly, so that the blown warm air flow can be more comprehensively blown to the mask 3, so that the external cold air is blown away, and the cold air is kept away from the outside of the mask 3, so as to avoid the cold air from contacting the outside of the heated mask 3, thereby avoiding the generation of water mist on the outside of the mask 3. In the whole process, through the opposite The heating of the mask 3 prevents the inner wall of the mask 3 from generating mist due to the large temperature difference between the mask 3 and the gas exhaled by the user. By continuously blowing air outside the mask 3, an "air curtain wall" is formed outside the mask 3 by relying on the blown air flow, so as to prevent the contact of the external cold air with the mask 3, thereby preventing the cold air from contacting the heated mask 3 to form mist outside the mask 3. Finally, it can be ensured that no mist is generated on both the inner and outer sides of the mask 3 when in use, thereby facilitating the doctor to observe the patient's breathing status through the mask 3. When not in use, the screw rod 20 is rotated forward to make it descend with the rectangular column 18, thereby bringing the squeeze The plate 17 descends, and the squeezing plate 17 presses against the end of the conduit 6 so that the end of the conduit 6 bends downward. As the squeezing plate 17 descends, the support 4 is used to squeeze multiple conduits 6. Finally, the end of the conduit 6 is located between the squeezing plate 17 and the support 4, and then the pipe opening of the conduit 6 is clamped and flattened, so that the pipe opening of the conduit 6 is closed, so as to prevent the fine dust from the outside from entering the conduit 6, which will block the conduit 6 for a long time and affect its normal ejection of airflow. The screw rod 20 is reversed to make it rise with the rectangular column 18, and vice versa, the squeezing plate 17 is reset, and the squeezing of the conduit 6 is cancelled, and the conduit 6 is reset under the support of its own toughness;When the mask 3 needs to be disassembled for replacement, the butt joint pipe is rotated to separate it from the input pipe 9, the pipe is rotated to separate it from the connecting pipe 7, and the pair of clamps 14 are pulled to move them away from each other, so that the spring 15 is compressed to deform it. With the separation of the pair of clamps 14, the clamping of the joint pipe 2 is cancelled, and then the entire bracket 4 is removed, so that the bracket 4 is separated from the joint pipe 2, and then the bracket 4 is separated from the mask 3. At this time, the joint pipe 2 can be separated from the mask 3, and then a new mask 3 is connected to the joint pipe 2, and then the bracket 4 is reset, and the pair of clamps 14 are pulled to separate them, and the pair of clamps 14 are moved outside the joint pipe 2, and the pair of clamps 14 are released. The spring 15 resets and the clamps 14 are reset, so that the joint pipe 2 is clamped, and then the pipe is connected to the connecting pipe 7, and the butt joint pipe is connected to the input pipe 9, so that the replacement of the mask 3 is completed. ;

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
