Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to an ear endoscope with air blowing and medicine delivery functions. Background Art

[0002] An otoscope can clearly display the structures of the external auditory canal, eardrum, and middle ear, allowing doctors to observe subtle lesions that are difficult to detect with the naked eye. This high-definition image display helps doctors accurately diagnose ear diseases such as otitis externa, otitis media, eardrum perforation, and cholesteatoma.

[0003] When examining the tympanic membrane, an inflatable otoscope is typically used. This otoscope has a built-in magnifying glass for observation. However, the magnifying glass's clarity is not as good as an otoscope's, and the intensity of the air during inflation is difficult to control, which can easily cause discomfort to the patient.

[0004] When the inside of a patient's ear is found to be damp, it needs to be dried to reduce the risk of infection. When medication is needed, it needs to be delivered deep into the ear. Existing otoscopes cannot quickly dry the ear or deliver medication deep into the affected area, resulting in poor treatment effectiveness.

[0005] Therefore, it is necessary to provide an ear endoscope with air blowing and medicine delivery functions. Utility Model Content

[0006] In order to solve the above problems, the purpose of the present invention is to provide an ear endoscope with blowing and medicine delivery functions, which has the functions of conveniently checking the condition of the eardrum, drying the ear and delivering medicine.

[0032] Specific embodiment 1, as Figure 1-5 The figure shows a preferred embodiment of the present invention. An ear endoscope with air blowing and medicine delivery functions mainly comprises a display and a mirror rod, a camera 8 is installed at the front end of the mirror rod, and the mirror rod and the display are wirelessly connected. The outer sleeve of the mirror rod is provided with a lens barrel 1, and the front end of the mirror rod extends out of the bottom of the lens barrel 1; a medicine tube 7 is detachably installed in the lens barrel 1, a barrel cover 2 is detachably installed on the barrel mouth of the lens barrel 1, a cover hole is provided on the barrel cover 2, and a cover plate 16 is detachably installed on the cover hole; a medicine hole is provided on the bottom of the lens barrel 1, and the first end of the medicine tube 7 is detachably installed on the cover hole, and the second end of the medicine tube 7 extends out of the lens barrel 1 through the medicine hole; a plurality of air holes 9 are provided on the bottom of the lens barrel 1, and an inflation tube 6 is provided on the side of the lens barrel 1, the first end of the inflation tube 6 is connected to the lens barrel 1, and the second end of the inflation tube 6 is detachably connected to the external inflation structure 5.

[0033] When the present invention is used, the doctor holds the lens barrel 1 and uses the camera 8 installed at the front end of the mirror rod inside the lens barrel 1 to examine the inside of the patient's ear. The patient's specific condition can be viewed through the display. Using the camera 8 and the display to examine the patient's ear is a prior art for otoscopes and will not be described in detail here. When it is necessary to examine the eardrum inside the patient's ear, an air-type otoscope is usually used for this purpose. The built-in magnifying glass of the air-type otoscope can clearly see the specific condition. The lens barrel 1 of the present invention is inserted into the patient's ear, and the external inflatable structure 5 is used to inflate the lens barrel 1 through the inflatable tube 6. The gas is blown out from the air hole 9 on the bottom of the lens barrel 1. The inspection principle is the same as that of the air-type otoscope and will not be described in detail here. There are many types of external inflatable structures 5 that can meet the inflation requirements. A rubber ball is just one of them and will not be listed here one by one. While blowing air, the camera 8 at the front end of the mirror rod can be used to view more clearly. The present invention uses the inflatable structure 5 to blow air into the air hole 9 of the lens barrel 1, which can not only be used to examine the eardrum, but also to dry the inside of the ear. Some patients experience dampness and discomfort after water enters their ears, and the present invention can be used to dry their ears. However, when using the inflatable structure 5 to blow air, if the air force is too strong, it can cause discomfort to the patient and may even damage the eardrum. Therefore, a removable buffer block 14 is mounted on the bottom of the lens barrel 1 to slow down the air flow. Furthermore, the buffer block 14 is made of multiple layers of breathable mesh that are stacked in an interlaced manner. The buffer block 14 is provided with holes 15 for the lens rod and medicine tube 7 to pass through. The buffer block 14 acts as a barrier. When air passes through the buffer block 14, the interlaced mesh blocks the air hole 9, preventing the air from directly passing through the air hole 9. After passing through the buffer block 14, the air flows to the air hole 9 at a slower rate, making the air flowing out of the air hole 9 gentler, significantly reducing irritation to the eardrum. Furthermore, the buffer block 14 has a honeycomb structure, and wind can pass through the buffer block 14. In order to better control the speed of gas outflow from the air hole 9, a decompression structure is further installed on the side of the lens barrel 1. The decompression structure mainly includes a decompression tube 3, which is connected to the lens barrel 1. The first end of the decompression tube 3 is installed on the side of the lens barrel 1, and the second end of the decompression tube 3 is installed with an airbag 4. When the inflatable structure 5 is inflated too quickly, the gas cannot pass through the buffer block 14 quickly, which will cause the air pressure in the lens barrel 1 to increase, causing the airbag 4 on the decompression tube 3 connected to the lens barrel 1 to expand. The airbag 4 can not only reduce the air pressure in the lens barrel 1 so that the wind force flowing out of the air hole 9 is not too strong, but also judge the size of the air pressure in the lens barrel 1 by the size of the expansion of the airbag 4, thereby adjusting the strength of the inflation of the inflatable structure 5, so that the air blown out of the air hole 9 can be used for tympanic membrane examination or for drying the inside of the ear.The lens barrel 1 of the present invention is also equipped with a removable medicine tube 7. Furthermore, a cannula 13 is mounted on the inner end surface of the barrel cap 2. The cannula 13 is disposed outside the cover hole, and the first end of the medicine tube 7 is plugged into the cannula 13. The first end of the medicine tube 7 is plugged into the cannula 13 of the barrel cap 2, and the second end of the medicine tube 7 passes through the medicine hole of the lens barrel 1 and out of the lens barrel 1. When a doctor uses a camera 8 at the front end of the lens barrel to examine the patient's ear and determines that the patient's ear requires medication, the doctor can open a dust-proof cover 16 on the barrel cap 2. The second end of the medicine tube 7 is located at the same end as the camera 8 of the lens barrel. Through observation by the camera 8, the doctor can insert the second end of the medicine tube 7 deep into the ear where medication is needed. The medicine is then injected into the medicine tube 7 through the cover hole in the barrel cap 2, allowing the medicine to directly reach the affected area, resulting in a more effective treatment. The medicine tube 7 can be removed for cleaning or replacement after use. If the barrel cap 2 becomes dirty, it can also be removed for cleaning. To prevent the drug extruded from the medicine tube 7 from contaminating the camera 8, the second end of the medicine tube 7 extends a distance beyond the camera 8. Furthermore, the second end of the medicine tube 7 is curved, with the curved opening facing inward. This facilitates entry of the medicine tube 7 into the ear and minimizes damage to the patient's ear skin. To install the medicine tube 7, the first end of the medicine tube 7 can be inserted into the lens barrel 1 through the medicine hole and then connected to the insertion tube 13 on the lens cap 2. The second end of the medicine tube 7 can be left outside the lens barrel 1.

[0034] The present invention requires frequent disinfection to avoid cross infection. Not only does it need to clean the outside of the lens barrel 1, but it also needs to clean the inside of the lens barrel 1. The screen plate must be removed from the lens barrel 1, the buffer block 14 must be replaced, the medicine tube 7 must be replaced, and then the inside of the lens barrel 1 must be cleaned. Furthermore, a mirror hole is provided at the bottom of the lens barrel 1, and the front end of the mirror rod is inserted into the mirror hole. The mirror rod can be removed from the lens barrel 1, making it easier to clean the lens barrel 1. Furthermore, a gasket is provided inside the mirror hole. The gasket can not only seal the lens but also increase friction. The gasket is used to fix the mirror rod.

[0035] After the examination, some patients do not need to use drug treatment and only need to undergo ear cleaning. Furthermore, a connecting rod 11 is detachably installed in the lens barrel 1. The connecting rod 11 and the medicine tube 7 are not installed in the lens barrel 1 at the same time. The first end of the connecting rod 11 is detachably connected to the cover hole. The second end of the connecting rod 11 is installed with an ear pick 10. The connecting rod 11 is inserted into the medicine hole, and the second end of the connecting rod 11 is located outside the lens barrel 1. When ear cleaning is needed, the barrel cover 2 is opened, the medicine tube 7 is separated from the barrel cover 2, the medicine tube 7 is taken out from one end of the medicine hole, the first end of the connecting rod 11 is inserted into the lens barrel 1 from the medicine hole, and connected to the cannula 13 on the barrel cover 2. One end of the ear pick 10 is left outside the lens barrel 1. The ear pick 10 can be conveniently used for ear cleaning through the camera 8 at the front end of the lens rod.

[0036] Specific embodiment 2, as Figure 6-7 As shown, based on the specific embodiment 1, only the decompression structure is changed. A decompression structure is installed on the side of the lens barrel 1. The decompression structure mainly includes a decompression pipe 3. The decompression pipe 3 is connected to the lens barrel 1. The first end of the decompression pipe 3 is installed on the side of the lens barrel 1. A piston is slidably connected to the decompression pipe 3. A stopper is provided on the second end of the decompression pipe 3. The piston and the decompression pipe 3 are not separated. A float rod 12 is installed on the outer end surface of the piston. The outer end surface refers to the side away from the lens barrel 1. The end of the float rod 12 extends out of the decompression pipe 3 and is provided with scale lines.

[0037] When the air pressure in the lens barrel 1 is too high, the piston slides outward on the pressure reducing tube 3, and the length of the float rod 12 on the piston extending out of the pressure reducing tube 3 increases. The distance moved by the float rod 12 can be known through the scale line, thereby knowing the extent to which the air pressure inside the lens barrel 1 exceeds the normal value.

[0038] The above description is a detailed description of the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modifications completed under the technical spirit suggested by the present invention should fall within the patent scope covered by the present invention.
