[0002] By using a drug delivery device based on the respiratory department, atomized liquid medicine or solid medicine is introduced into the patient's nasal cavity to treat the patient. However, the humidity of the water vapor obtained after atomization will increase. If it is directly inhaled into the patient's body, it may choke the patient. In addition, the inner wall of the pipe of the drug delivery device may also produce water droplets due to the long-term passage of water vapor, thereby affecting the normal use of the drug delivery device pipe. In addition, the water vapor obtained after atomization is generally cooler. If the patient inhales the cooler gas for a long time, it may also cause lung discomfort. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 5 As shown, the utility model provides a drug delivery device based on the respiratory department, including a flexible connecting tube 1, the right end of the flexible connecting tube 1 is fixedly connected with an air inlet pipe 2, the right end of the air inlet pipe 2 is threadedly connected with a water filter pipe 3, the inner cavity of the water filter pipe 3 is fixedly installed with a water filter cotton 4, the right end of the water filter pipe 3 is fixedly installed with a connector 5, the left side of the air inlet pipe 2 is fixedly installed with a heat-conducting sleeve 7, the top of the heat-conducting sleeve 7 is fixedly installed with a micro heater 8, the inner wall of the heat-conducting sleeve 7 is fixedly installed with a metal heat-conducting sheet 9, the left sides of the front and rear ends of the flexible connecting tube 1 are fixedly installed with a plug-in tube 10, the outer surface of the plug-in tube 10 is fixedly installed with a baffle 11, and the left side of the plug-in tube 10 is fixedly installed with an air outlet head 16;

[0021] By connecting the output end of the atomizing device with the connector 5, the water vapor after the atomization of the medicine is output to the inner cavity of the water filter tube 3 through the atomizing device, and the moisture in the water vapor is first filtered through the water filter cotton 4 to prevent the water vapor from containing too much water, which may cause the patient to have difficulty breathing and the inner wall of the soft connecting tube 1, the air inlet pipe 2, and the plug-in tube 10 to form water droplets, thereby ensuring the normal use of the device, and then starting the micro heater 8 to transfer heat to the metal heat conductive sheet 9 through the heat conductive sleeve 7, so that the water vapor in the inner cavity of the air inlet pipe 2 is heated by the metal heat conductive sheet 9, thereby preventing the patient from having breathing discomfort caused by the low water vapor temperature.

[0022] A baffle 11 is fixedly installed on the outer surface of the plug-in tube 10, a fixing sleeve 12 is movably mounted on the outer surface of the plug-in tube 10, a connecting block 13 is fixedly installed on the side of the fixing sleeve 12 away from the plug-in tube 10, a spring 14 is fixedly installed on the side of the connecting block 13 away from the fixing sleeve 12, and a damping telescopic rod 15 is fixedly installed on the side of the connecting block 13 away from the fixing sleeve 12;

[0023] By shortening the distance between the two insertion tubes 10, inserting them into the patient's nasal cavity, and then loosening the insertion tubes 10, the tension provided by the spring 14 causes the distance between the insertion tubes 10 to open, so that the insertion tubes 10 will contact the patient's nasal cavity and fix the insertion tubes 10, thereby preventing the insertion tubes 10 from being unable to be fixed and slipping off.

[0024] The outer surface of the right side of the air inlet pipe 2 and the inner wall of the left side of the water filter pipe 3 are both provided with a thread groove 6, and the air inlet pipe 2 and the water filter pipe 3 are threadedly connected through the thread groove 6;

[0025] The air intake pipe 2 and the water filter pipe 3 are threadedly connected via the thread groove 6, so that the water filter pipe 3 can be unscrewed from the surface of the air intake pipe 2, and then the water filter pipe 3 can be replaced, thereby avoiding the situation where the water filter cotton 4 cannot continue to absorb water after absorbing too much water.

[0026] The water filter cotton 4 is in a round tube shape, the outer surface of the water filter cotton 4 is fixedly connected to the inner wall of the water filter pipe 3, and the flexible connecting pipe 1 is in a C shape;

[0027] The water filter cotton 4 is in a circular tube shape, so that water vapor can pass through the inner cavity of the water filter cotton 4, so that the water filter cotton 4 can absorb part of the moisture in the water vapor, thereby preventing a large amount of moisture from entering the patient's lungs and causing discomfort to the patient, and preventing excessive moisture from accumulating on the inner walls of the flexible connecting tube 1, the air inlet pipe 2, and the plug-in tube 10. The flexible connecting tube 1 is in a C shape, so that the flexible connecting tube 1 can divert the water vapor, so that the water vapor can be input into the patient's nasal cavity through the two plug-in tubes 10.

[0028] There are four baffles 11 in total, and the four baffles 11 are fixedly mounted on the outer surfaces of the two plug-in tubes 10 respectively, and the fixing sleeve 12 is located between the two baffles 11;

[0029] Four baffles 11 are respectively fixedly installed on the outer surfaces of the two plug-in tubes 10, and the fixing sleeve 12 is located between the two baffles 11, so that the fixing sleeve 12 is limited by the baffles 11, so that the tension provided by the spring 14 can be evenly applied to the fixing sleeve 12, thereby driving the two plug-in tubes 10 to contact the nasal cavity, effectively preventing the fixing sleeve 12 from deviating.

[0030] The damping telescopic rod 15 is located at the center of the inner cavity of the spring 14, and the connecting blocks 13 are fixedly mounted on the front and rear sides of the spring 14 respectively;

[0031] The tension provided by the spring 14 pushes the insertion tube 10 toward the upper and lower sides of the spring 14 , so that the outer surface of the insertion tube 10 contacts the nasal cavity, thereby fixing the insertion tube 10 to prevent the insertion tube 10 from slipping during use, which would affect the drug administration effect. The spring 14 is then positioned and guided by the damping telescopic rod 15 to prevent the spring 14 from deflecting during the deformation process, and the force provided by the spring 14 can be evenly applied to the insertion tube 10 through the connecting block 13 .

[0032] The working principle and use process of the utility model are as follows: the distance between the two insertion tubes 10 is reduced, and then the two insertion tubes 10 are inserted into the patient's nasal cavity, and then the two insertion tubes 10 are pushed open by the tension provided by the spring 14, so that the outer surface of the insertion tube 10 contacts the inside of the nasal cavity, thereby fixing the insertion tube 10;

[0033] The output end of the drug atomization device is fixedly connected to the connector 5. The water vapor sprayed by the drug atomization device first contacts the water filter cotton 4, thereby absorbing most of the water in the water through the water filter cotton 4. When the water filter cotton 4 absorbs a lot of water, the water filter pipe 3 and the air inlet pipe 2 can be unscrewed through the threaded groove 6 to replace the water filter pipe 3. Then the water vapor passes through the inner cavity of the heat-conducting sleeve 7. At this time, heat is generated by starting the micro heater 8. Then the heat is transferred to the metal heat-conducting sheet 9 through the heat-conducting sleeve 7, so that the metal heat-conducting sheet 9 contacts the water vapor and transfers the heat to the water vapor. Then the water vapor is diverted through the soft connecting pipe 1, and then the water vapor is output to the nasal cavity through the plug-in pipe 10 and the air outlet head 16.
