A movable slide rail 1031 is installed on the side wall of the screw ring 1022, and the movable slide rail 1031 is slidably arranged on the fixed seat 103. When the operator needs to start the micro motor 102, the micro motor 102 drives the screw shaft 1021 connected to the output shaft, and the screw ring 1022 is meshed on the screw shaft 1021. The screw ring 1022 can slide in the limited slide rail 1023, which plays a role of limiting, and then can drive the screw ring 1022 to move left and right.

[0048] Embodiment 2:

[0049] The difference between the above embodiment and this embodiment is that: Figures 1 to 10 As shown, in a specific embodiment, a vertical plate 1032 is installed at the bottom of the fixed seat 103, and a guide wheel 1033 is installed horizontally on the vertical plate 1032. The guide wheel 1033 slides on the guide slope 1051, and the length of the guide plate 105 is adapted to the length of the screw shaft 1021. When the screw ring 1022 moves, the screw ring 1022 drives the moving slide rail 1031 on the surface to move synchronously, and drives the fixed seat 103 to move left and right synchronously. The vertical plate 1032 is set at the bottom of the fixed seat 103, and the guide wheel 1033 is set at the bottom of the vertical plate 1032. The guide wheel 1033 rolls on the guide slope 1051, and the fixed seat 103 can move horizontally while moving up and down.

[0050] like Figures 1 to 10 As shown, a sleeve 104 is installed on the fixed seat 103, and a positioning rod 1041 is slidably inserted on the sleeve 104, and a spring is installed inside the sleeve 104, one end of the spring is clamped on the bottom of the sleeve 104, and the other end is clamped on the positioning rod 1041. A positioning slide rail 1042 is slidably provided on the top of the positioning rod 1041, and the positioning slide rail 1042 is installed on the pressure cover 101. The spring in the sleeve 104 can apply pressure to itself, and the sleeve 104 can push the fixed seat 103 to have a downward movement force, thereby ensuring that the guide wheel 1033 on the fixed seat 103 can always contact the guide slope 1051.

[0051] like Figures 1 to 10 As shown, further, a clamping plate 106 is installed on the side wall of the fixed seat 103, and a sliding sleeve 1061 is rotatably installed on the clamping plate 106. The sliding sleeve 1061 is slidably plugged on the injection pipe 107. A rotating shaft 1071 is installed on the side wall of the injection pipe 107. The rotating shaft 1071 is rotatably installed on the hollow slider 1014, and a torsion spring is clamped between the side wall of the injection pipe 107 and the hollow slider 1014. In the process of the fixed seat 103 moving up and down, the clamping plate 106 at the end drives the sliding sleeve 1061 to slide up and down. In the process of moving, the sliding sleeve 1061 can pull the injection pipe 107 and the rotating shaft 1071 to rotate, so as to adjust the first nozzle 108 and the detection camera 1081 at the end of the injection pipe 107, so as to ensure that the first nozzle 108 and the detection camera 1081 can be rotated to different positions, thereby improving the accuracy of spraying.

[0052] Embodiment 3:

[0053] The difference between the above embodiment and this embodiment is that: Figures 1 to 10As shown, the inner wall of the nasal plug sleeve 201 is provided with an installation cavity 2012, and a synchronization plate 2021 is slidably arranged on the installation cavity 2012. One side of the synchronization plate 2021 is connected to the expansion plate 202, and an unlocking block 2022 is installed on the other side of the synchronization plate 2021. The unlocking block 2022 movably passes through the side wall of the nasal plug sleeve 201. The height of the unlocking block 2022 is the same as the height of the expansion plate 202. The unlocking block 2022 needs to be pressed, and the unlocking block 2022 drives the synchronization plate 2021 to slide downward, and the expansion plate 202 on the synchronization plate 2021 moves downward synchronously. When the nasal plug sleeve 201 is inserted into the nasal cavity, the unlocking block 2022 is released, and the expansion plate 202 moves outward, thereby fitting with the inner wall of the nasal cavity, thereby achieving the purpose of installation.

[0054] like Figures 1 to 10 As shown, in a specific embodiment, a limit rod 203 is vertically installed on the installation cavity 2012, the limit rod 203 and the synchronization plate 2021 are movably plugged, and a return spring 2031 is sleeved on the limit rod 203, one end of the return spring 2031 is clamped on the inner wall of the installation cavity 2012, and the other end of the return spring 2031 is clamped on the bottom of the synchronization plate 2021. During the sliding process of the synchronization plate 2021, the synchronization plate 2021 slides on the limit rod 203, which achieves the purpose of limited movement.

[0055] like Figures 1 to 10As shown, further, a connecting sleeve 3011 is installed on one side of the input conduit 301, a three-way joint 3012 is installed on one end of the input conduit 301, and the other two joints of the three-way joint 3012 are respectively connected to the first diversion conduit 3013 and the second diversion conduit 3014, the outer wall of the three-way joint 3012 and the T-shaped plate 302 are interconnected, and the side wall of the T-shaped plate 302 is installed with a side panel 3022, and the side panel 3022 is interconnected with the corresponding first diversion conduit 3013 and the second diversion conduit 3014. A partition 3021 is installed on the top of the T-shaped plate 302, and a synchronization shaft 3032 is movably provided on the partition 3021. One side of the synchronization shaft 3032 is interconnected with the cam 303, and the other side of the synchronization shaft 3032 is interconnected with the friction wheel 3031. A mounting bracket 3023 is installed on the partition 3021, and a crank 304 is installed on the mounting bracket 3023. The crank 304 and the synchronization shaft 3032 are interconnected, and a handle 3041 is installed on the crank 304. When it is necessary to adjust the opening and closing of the first shunt duct 3013 and the second shunt duct 3014, the operator can drive the crank 304 to rotate through the handle 3041, and the crank 304 drives the synchronization shaft 3032 to rotate, thereby driving the friction wheel 3031 to rotate, and the friction wheel 3031 engaged with the side wall rotates synchronously in the opposite direction, and the two cams 303 rotate synchronously in the opposite direction, so when one cam squeezes and closes the shunt duct, the other shunt duct is in an open state, thereby achieving the purpose of controlling the flow direction of the liquid, and the connecting sleeve 3011 can be plugged into the syringe. At this time, the operator presses the syringe, and then the liquid medicine in the syringe can be input into the input duct 301. The cam 303 can ensure that the liquid medicine can flow to the designated separation duct, and then flow to the oral spray assembly 100 or the nasal spray assembly 200 to spray the designated position.

[0056] The implementation principle of the device for precise spraying into the nasal cavity and oral cavity of this embodiment is as follows:

[0057] When the oral spray assembly 100 needs to be used, the pressure cover 101 needs to be placed in the patient's oral cavity first, and then the patient needs to bite the alveolar groove 1011 to ensure the depth of the pressure cover 101 extending into the oral cavity through the alveolar groove 1011. Then the operator needs to start the micro motor 102, and the micro motor 102 drives the screw shaft 1021 connected to the output shaft. The screw shaft 1021 is meshed with a screw ring 1022, which can slide in the limiting slide rail 1023 to play a limiting role, and then can drive the screw ring 1022 to move left and right.

[0058] When the screw ring 1022 moves, the screw ring 1022 drives the movable slide rail 1031 on the surface to move synchronously, and drives the fixed seat 103 to move left and right synchronously. A vertical plate 1032 is set at the bottom of the fixed seat 103, and a guide wheel 1033 is set at the bottom of the vertical plate 1032. The guide wheel 1033 rolls on the guide slope 1051, and the fixed seat 103 can move horizontally while moving up and down.

[0059] The sleeve 104 on the fixed seat 103 can move up and down synchronously, and the spring in the sleeve 104 can apply pressure to itself. The sleeve 104 can push the fixed seat 103 to have a downward movement force, thereby ensuring that the guide wheel 1033 on the fixed seat 103 can always contact the guide slope 1051.

[0060] During the up and down movement of the fixing seat 103, the clamping plate 106 at the end drives the sliding sleeve 1061 to slide up and down. During the movement of the sliding sleeve 1061, the injection pipe 107 and the rotating shaft 1071 can be pulled to rotate, thereby adjusting the first nozzle 108 and the detection camera 1081 at the end of the injection pipe 107, ensuring that the first nozzle 108 and the detection camera 1081 can be rotated to different positions, thereby improving the accuracy of spraying. The liquid medicine is input through the first diversion conduit 3013.

[0061] When it is necessary to apply medicine to the nasal cavity, the operator first needs to press the unlocking block 2022. The unlocking block 2022 drives the synchronous plate 2021 to slide downward, and the expansion plate 202 on the synchronous plate 2021 moves downward synchronously. When the nasal plug sleeve 201 is inserted into the nasal cavity, the unlocking block 2022 is released, and the return spring 2031 is used to facilitate the expansion plate 202 to move outward, so that it fits the inner wall of the nasal cavity, thereby achieving the purpose of installation.

[0062] In the process of the synchronous plate 2021 sliding, the synchronous plate 2021 slides on the limiting rod 203, which achieves the purpose of limiting movement. The liquid medicine is input into the nasal cavity through the second shunt catheter 3014.

[0063] When it is necessary to adjust the opening and closing of the first diversion duct 3013 and the second diversion duct 3014, the operator can drive the crank 304 to rotate through the handle 3041, and the crank 304 drives the synchronization shaft 3032 to rotate, and then drives the friction wheel 3031 to rotate, and the friction wheel 3031 engaged with the side wall rotates synchronously in the opposite direction, and the two cams 303 rotate synchronously in the opposite direction, so when one cam squeezes and closes the diversion duct, the other diversion duct is in an open state, thereby achieving the purpose of controlling the flow direction of the liquid.

[0064] At this time, the operator can insert the connecting sleeve 3011 into the syringe, and then press the syringe to input the liquid medicine in the syringe into the input catheter 301, wherein the opening and closing of the shunt catheter can be adjusted by the cam described above, thereby ensuring that the liquid medicine can flow to the designated separation catheter, and then flow to the oral spray assembly 100 or the nasal spray assembly 200 to spray the medicine at the designated position.
