The specific implementation process comprises the following steps:
in an initial state, the piston 6 is positioned inside the limiting tube 4, and the piston 6 does not block a gap between the limiting tube 4 and the top wall of the tube body 1;
when a patient needs to take medicine, firstly, the device is inverted, so that glucocorticoid liquid medicine in the liquid storage area enters the medicine administration part 2 through a gap between the limiting pipe 4 and the pipe body 1, then the push rod 7 is slowly pushed towards the direction of the medicine administration part 2, after the piston 6 enters the medicine administration part 2, the device is reset, so that the medicine administration part 2 is placed upwards, then the push rod 7 is pushed upwards, and under the action of the piston 6, the liquid medicine in the medicine administration part 2 just flows out through the atomizing head 3; then the medicine feeding part 2 of the device is plugged into the nostril of a patient, the air inlet 12 is sealed by the thumb, the air feeding ball 11 is in an expansion state, the air feeding ball 11 is pressed, the check valve 14 is opened, the air inside the air feeding ball 11 enters the air bag 8 through the catheter 13, then the thumb is far away from the air inlet 12, the check valve 14 is closed, the air feeding ball 11 is reset due to certain elasticity of the air feeding ball 11, the external air enters the air feeding ball 11 through the air inlet 12 and is pressed for a plurality of times to inflate the air bag 8, at the moment, the caliber of the air feeding port 9 arranged on the air bag 8 is small, and the push rod 7 is pressed in the middle to ensure that the liquid medicine in the medicine feeding part 2 is sprayed out for a short time through the atomizing head 3, so that the air inside of the air bag 8 can meet the requirement of blowing the liquid medicine to the deep part of the nasal cavity, at the moment, the patient clamps the tube body 1 by the index finger and the middle finger, and the index finger contact with the ring ear on the side surface close to the medicine feeding part 2, the end part of the push rod 7 is pressed by the thumb, so that the push rod 7 drives the piston 6 to slide in the administration part 2, the liquid medicine in the administration part 2 is sprayed out through the atomizing head 3, the liquid medicine is in a mist shape, the acceleration of the liquid medicine moving to the deep part of the nasal cavity is continuously reduced under the action of wind blown out from the air supply port 9 by the atomized liquid medicine, and at the moment, under the action of wind blown out from the air bag 8 through the air supply port 9, the mist liquid medicine can effectively move to the deep part of the nasal cavity, so that the possibility that the liquid medicine reaches the ethmoid sinus and the frontal sinus is improved;
before the device is used next time, firstly, the push rod 7 is pulled downwards for a certain distance, the piston 6 is still positioned in the medicine feeding part 2, then the push rod 7 is pushed to enable the liquid medicine above the piston 6 in the medicine feeding part 2 to be sprayed out through the atomizing head 3, and then the medicine feeding operation is repeated;
the foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
