Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an endoscopic sterilization device for otolaryngology. Background Technology

[0002] Otorhinolaryngological endoscopy is a comprehensive examination of the mucous membranes and tissues of the ears, nose, and throat. An otolaryngoscope is an optical device used in otolaryngology to comprehensively examine the mucous membranes and tissues of these areas. An ear endoscope can check for ulcers and swelling of the ear mucosa, fluid accumulation, tympanic membrane perforation, presence of any other organisms in the ear, and ear canal patency. A nasal endoscope can also provide direct visualization of the nasal cavity, checking for nasopharyngeal patency, polyps, lumps, deviations or fractures of the nasal bones, and nasal discharge. A laryngoscope is used to check for pharyngeal patency and the presence of polyps, cysts, tumors, or other growths on the vocal cords. Otorhinolaryngological examinations typically require the use of nasal endoscopes and laryngoscopes. Since these endoscopes come into contact with the patient's tissues, they require strict disinfection after each use. Inadequate disinfection can lead to bacterial residue and cross-infection, impacting the patient's health.

[0003] Existing ENT endoscope disinfection devices, such as the one described in application number CN202111566645.8 (belonging to the field of medical disinfection device technology), specifically address the issue that current endoscope disinfection primarily relies on manual cleaning of the endoscope surface with alcohol swabs. This method is inefficient and prone to bacterial residue. The proposed solution includes a disinfection box with a door rotatably connected to its front side. A controller is fixedly installed on the top front side of the door. A disinfectant solution tank is fixedly installed on the inner wall of the bottom right side of the disinfection box. The left side of the disinfectant tank is rotatably connected to a water-absorbing component, and the right end of the water-absorbing component extends into the disinfectant tank and is fixedly connected to a flexible tube. This invention has a reasonable structure; by starting the drive motor, it can heat and spray the disinfectant solution and adjust the position of the endoscope. Therefore, it can achieve comprehensive disinfection of the endoscope and has good ease of use. However, in the above technology, the water flowing out can easily cause contamination of the worm gear, leading to bacterial growth and affecting the subsequent disinfection quality. Therefore, we propose an ENT endoscope disinfection device to solve the above problems. Summary of the Invention

[0035] A lamp holder 607 is provided on the opposite side of the upper convex base 606, and an ultraviolet lamp 608 is provided on the opposite side of the lamp holder 607.

[0036] In an embodiment of the present invention, the lamp holder 607 on the upper convex base 606 is then used in conjunction with the ultraviolet lamp 608 to turn it on.

[0037] The working principle of this invention is as follows: In use, the equipment is raised to a certain height by the lifting frame 101 and the folded base 102, so that the bottom frame 103 and the bolt base 104 can be used to effectively assemble and combine the bearing box 105, allowing the control panel 106 on the bearing box 105 to effectively control the output. When processing is required, the ENT endoscope product 3 is used to plug and fix the endoscope socket 2011 one by one, so that the external hydraulic cylinder 201 outputs power to drive the output end to run, and after the external hydraulic cylinder 201 outputs power to run, the external hydraulic frame 202 and the connecting bar 203 will extend and retract. After operation, the base cover 204 covers the bearing housing 105, and the top cylinder 205 outputs power to drive the output end, causing the lifting bar 206 to insert the lower slot 2010 on the lower cover 209 into the splined spindle 506. When cleaning is required, the control pump 407 is used to operate, drawing water from the opened inlet valve 408. The cleaning water is then fed into the nozzle 4010 at the output end of the distributor 409 to achieve a spraying effect. Then, the transmission motor 503 outputs power to drive the output end, causing the transmission motor 503 to output power to... The first gear set 504 on the speed-clamping housing 502 engages with the second gear set 505 for high-speed transmission. When the second gear set 505 engages, the splined spindle 506 drives the central column 208, lower cover 209, and lower slot 2010 to rotate at high speed. This rotation, via the central column 208, lower cover 209, and lower slot 2010, causes the ENT endoscope product 3 to rotate at high speed. This, in turn, causes the locking base plate 402, in conjunction with the electric rotating seat 403, to rotate the rotating rod 404 and brush strip 405 at high speed, achieving a physical cleaning effect. This is further enhanced by the drain valve 4011 and... The temporary storage tank 4012 temporarily stores the wastewater. Then, the air intake fan 605 on the air chamber 604 outputs air force, and the heating rod 603 on the heating chamber 602 outputs heat, so that the hot air is input into the carrying box 105 to dry the product. Then, the lamp holder 607 on the upper convex base 606 is used in conjunction with the ultraviolet lamp 608 to turn on. After the ultraviolet light is turned on, the outer oil cylinder 201 and the outer oil rack 202 operate in conjunction with the upper top oil cylinder 205 and the lifting bar 206 to effectively output and operate, so as to achieve the drying effect and effectively disinfect the product.
