[0002] Otolaryngology sprayers are a common tool used in otolaryngology to apply medication to patients. They are mainly used to spray medication into deeper areas such as the ear canal, nasal cavity, or throat. A novel visual ENT spray device, disclosed in patent CN205198671U, comprises a medicine storage bottle, a liquid guide tube, an air guide tube, a display device, an electronic endoscope, and an LED light. The medicine storage bottle has a cap, on which are mounted the air guide tube and the liquid guide tube. One end of the liquid guide tube extends into a transparent tubing, which has a handle. One end of the transparent tubing is closed into a hemispherical shape, with an electronic endoscope and an LED light at its end. The electronic endoscope and LED light are connected to the display device via wires, and the display device has a handle at its lower end. However, in this patent document, during spraying, one end of the liquid guide tube usually comes into contact with the patient's treatment area, resulting in a high probability of the liquid guide tube becoming covered with the patient's secretions. When the liquid guide tube needs to be replaced, it must be pulled out of the transparent tubing, which results in the transparent tubing still containing the patient's secretions, increasing the difficulty of cleaning the transparent tubing, reducing the device's hygiene performance, and making it inconvenient to use.

[0003] While existing technologies may already offer solutions to the aforementioned problems, this case aims to provide an alternative or replacement technical solution. Utility Model Content

[0021] Example: Those skilled in the art shall connect all electrical components and their compatible power supplies in this case with wires, and select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence shall refer to the working principle described below, in which the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without explaining the electrical control.

[0022] Please see Figure 1-4 A visual spraying device for otolaryngology includes a handle 1, a battery box 2 installed at the upper end of the handle 1, a display screen 3 installed on one side wall of the battery box 2, a visual spraying structure installed on the other side wall of the battery box 2, and a storage structure installed at the lower end of the handle 1.

[0023] It should be noted that battery box 2 contains batteries for powering electrical components;

[0024] Specifically, the visual spraying structure includes an extension rod 4, an endoscope 5 installed at one end of the extension rod 4, a guide strip 6 installed at the lower end of the extension rod 4 along the axial direction of the extension rod 4, a slider 7 movably installed on the guide strip 6, a spatula 8 installed on the side wall of the slider 7, multiple open clamping components installed at equal intervals along the axial direction on the extension rod 4, and a dispensing tube 9 movably installed on the multiple open clamping components. The dispensing tube 9 movably fits against the lower wall of the guide strip 6. Each open clamping component includes two L-shaped strips 10, which are symmetrically installed on the extension rod 4 with the guide strip 6 as the center. An external threaded connector 11 is installed at one end of the dispensing tube 9, and a storage structure is installed at one end of the internal threaded connector.

[0025] It should be noted that medical staff hold handle 1 and insert extension rod 4 and dispensing tube 9 into the patient's ear, nose, and throat area. Endoscopic lens 5 is used to photograph the patient's ear, nose, and throat area, and display screen 3 is used to display the image captured by endoscopic lens 5, making it easier for medical staff to aim dispensing tube 9 at the ear, nose, and throat area. When spraying, the liquid in the storage structure is sprayed out from dispensing tube 9. After spraying, extension rod 4 and dispensing tube 9 are removed from the patient's ear, nose, and throat area. Then, medical staff hold the lower part of slider 7 and move slider 7 laterally, which moves shovel 8 to make dispensing tube 9 disengage from the two L-shaped strips 10 until dispensing tube 9 is completely detached from the device. Gradually and gently release the fixation between dispensing tube 9 and open clamping assembly, reducing the risk of damage to open clamping assembly caused by directly pulling dispensing tube 9 and extending the service life of the device. At the same time, the open clamping assembly is an open type that clamps and limits dispensing tube 9, making it easier for medical staff to clean and disinfect the device after spraying, thus improving the hygiene and safety factor.

[0026] Specifically, the storage structure includes a cover 12, which is installed on the lower wall of the handle 1. A storage bottle is connected to the cover 12 by threads. The storage bottle includes a rigid section 13 and a flexible section 14. The rigid section 13 is installed on the cover 12 by threads, and the flexible section 14 is located at one end of the rigid section 13. A suction tube 15 is inserted into the cover 12. A drug supply pump 16 is installed at one end of the suction tube 15. A connecting tube 17 is installed on the drug supply pump 16. An internal threaded connecting cap 18 is installed at one end of the connecting tube 17, and an external threaded connector 11 is installed on the internal threaded connecting cap 18.

[0027] It should be noted that the storage bottle stores the liquid medicine, and the suction tube 15 extends into the bottom of the storage bottle. The liquid medicine is drawn into the suction tube 15 by the operation of the supply pump 16. After passing through the supply pump 16 and the connection of the external threaded connector 11, the liquid medicine enters the outlet tube 9 and is sprayed out from the end of the outlet tube 9. The design of the flexible section 14 allows the inside of the storage bottle to undergo a certain deformation when the liquid medicine is extracted, which balances the pressure difference between the inside and outside to a certain extent. The threaded connection of the external threaded connector 11 makes it easy to replace the new outlet tube 9.

[0028] Preferably, and further still, a power button 19 is installed on the handle 1 for turning the device on and off;

[0029] As a preferred and further option, a spray button 20 is installed on the handle 1 and below the power button 19. When the spray button 20 is pressed, the pesticide pump 16 will spray. When the spray button 20 is released, the pesticide pump 16 will stop working.

[0030] As a preferred and further option, an illumination lamp 21 is installed at one end of the extension rod 4. When medical staff operate the power switch button 19 to turn on the device, the endoscope 5 and the illumination lamp 21 work simultaneously to increase the brightness and facilitate the endoscope 5 to capture images.

[0031] Preferably, the slider 7 has a Y-shaped structure, and the width of the slider 7 is smaller than the distance between the two L-shaped bars 10, so that the slider 7 can move smoothly between the two L-shaped bars 10.

[0032] Preferably, the lower end of the slider 7 is located below the lower ends of the two L-shaped bars 10, which makes it easier for medical staff to hold the slider 7 and move it laterally.

[0033] As a preferred and further option, the upper wall surface of the shovel 8 is movably attached to the lower wall surface of the guide strip 6, which facilitates the removal of the dispensing tube 9 from the device.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
