Description

Technical Field

[0001] The invention relates to the technical field of medical appliances, and in particular to an ear canal cleaner for otolaryngology. Background Art

[0002] Otolaryngology is a department that diagnoses and treats the ears, nose, pharynx, larynx, and related head and neck areas. When treating and caring for patients with ear canal diseases, otolaryngologists need to provide corresponding treatment and care based on the actual conditions of the patients, for example:

[0003] When inflammation occurs in the patient's ear canal, the inner ear canal needs to be flushed with hydrogen peroxide or saline, and the ear canal needs to be kept dry after flushing;

[0004] When there is dirt or foreign matter in the patient's ear canal, it is necessary to use a clip to remove the dirt or foreign matter. If necessary, sodium bicarbonate solution needs to be injected into the ear canal to perform an ear bath. After cleaning, the ear canal needs to be kept dry.

[0005] When observing the inside of the ear canal, you need to use tweezers to open the ear canal, and then use a searchlight to shine into the ear canal. When you need to flush the ear canal, in addition to opening the outer ear and using a searchlight to shine, you also need to insert the flushing head into the ear canal. When you need to remove dirt or foreign objects, you need to use a searchlight on one side and use tweezers on the other side to probe deep into the ear canal.

[0006] From the above, it can be seen that multiple medical instruments are needed to cooperate in the care and treatment of the ear canal, which makes the operation more troublesome. Therefore, the prior art lacks an instrument that can open the ear canal, illuminate the inside of the ear canal, flush the ear canal and remove dirt. Summary of the invention

[0007] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides an ear canal cleaner for otolaryngology to solve the above problems.

[0008] In order to achieve the above object, the technical solution adopted by the present invention is:

[0009] An ear canal cleaner for ENT department comprises a rotating cylinder, a hard tube, an inner support sheet and a main cylinder;

The first rotating plate and the second rotating plate are both fixed on the side surface of the connecting rod. The fixing plate is fixed inside the main cylinder and is located between the first rotating plate and the second rotating plate. The liquid suction barrel is adhesively fixed between the first rotating plate and the fixing plate. The liquid inlet of the liquid suction barrel is the liquid inlet of the liquid discharging assembly. The liquid outlet barrel is adhesively fixed between the second rotating plate and the fixing plate.

[0047] Next, each embodiment of the present invention will be described in detail with reference to the Figures 1 to 6 accompanying drawings. Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0048] As shown in the Figure 1 - accompanying Figure 6 drawings, an ear canal cleaner for otolaryngology includes a rotary cylinder 3, a hard tube 5, an inner support piece 6 and a main cylinder 8;

[0049] Main cylinder 8: The diameter of the lower end of the main cylinder 8 is smaller than that of the upper end. Hold the upper end of the main cylinder 8, so that the thinner lower end is inserted into the ear canal. A vent hole 4 is provided on the side surface of the upper end of the main cylinder 8, so that the air flow inside and outside the main cylinder 8 is unblocked. A first fan 17 and a second fan 18 are fixed inside the main cylinder 8. The side surface of the main cylinder 8 is of an open structure and a rotary door 7 is rotatably arranged. Opening the rotary door 7 can expose the inside of the main cylinder 8;

[0050] Insertion rods 20 are movably passed through the side surface of the lower end of the main cylinder 8 in a circular array. An inner support piece 6 is fixed at the end of the insertion rod 20 outside the main cylinder 8. The inner support piece 6 can be made of silica gel material to avoid damaging the inner wall of the ear canal;

[0051] Inside the main cylinder 8, a partition plate 15 is fixed. A hose 14 passes through the partition plate 15. The hose 14 is made of medical silicone material, can be stretched or shortened, and can also be deformed. There are four hoses 14, and a rigid tube 5 is fixed to the lower end of each hose 14, that is, there are also four rigid tubes 5. The air outlet end of the first blower 17 and the air inlet end of the second blower 18 are both fixed with an air tube 16, and the two air tubes 16 are respectively inserted into two adjacent hoses 14;

[0052] Rotating cylinder 3: The lower end of the rotating cylinder 3 rotates inside the upper end of the main cylinder 8. The center of the lower end of the rotating cylinder 3 is fixed with a connecting rod 11. The connecting rod 11 is located inside the main cylinder 8 and is exactly in the middle of the four rigid tubes 5. A lighting lamp 13 is fixed inside the lower end of the connecting rod 11;

[0053] A first transmission assembly 19 is installed between the connecting rod 11 and the inserting rod 20. When the connecting rod 11 rotates, it drives the inserting rod 20 to enter and exit the main cylinder 8 through the first transmission assembly 19. A second transmission assembly 21 is installed between the connecting rod 11 and the main cylinder 8. The four rigid tubes 5 are located inside the second transmission assembly 21. When the connecting rod 11 rotates, it drives the four rigid tubes 5 to approach or move away from each other through the second transmission assembly 21. A liquid discharge assembly 12 is installed between the connecting rod 11 and the main cylinder 8. The liquid inlet and outlet of the liquid discharge assembly 12 are respectively inserted into the other two hoses 14 in a movable manner. When the connecting rod 11 rotates, it squeezes the liquid discharge assembly 12 to make the liquid inside the liquid discharge assembly 12 enter and exit the hose 14.

[0054] In this embodiment, referring to the attached Figure 3 , a battery 10 is fixed inside the rotating cylinder 3. A control switch 9 is fixed on the side of the rotating cylinder 3. The output end of the battery 10 is electrically connected to the input end of the control switch 9. The output end of the control switch 9 is electrically connected to the input ends of the lighting lamp 13, the first blower 17, and the second blower 18. The upper end of the rotating cylinder 3 is of an open structure. A screw cap 2 is screwed onto the upper end of the rotating cylinder 3. A charging port 1 is fixed at the center of the screw cap 2. The charging port 1 is electrically connected to the input end of the battery 10.

[0055] In this embodiment, referring to the attached Figure 6 , the liquid discharge assembly 12 includes a first rotating plate 121, a liquid suction barrel 122, a fixing plate 123, a liquid discharge barrel 124, and a second rotating plate 125. The first rotating plate 121 and the second rotating plate 125 are both fixed on the side of the connecting rod 11. The fixing plate 123 is fixed inside the main cylinder 8. The fixing plate 123 is located between the first rotating plate 121 and the second rotating plate 125. The liquid suction barrel 122 is adhesively fixed between the first rotating plate 121 and the fixing plate 123. The liquid inlet of the liquid suction barrel 122 is the liquid inlet of the liquid discharge assembly 12. The liquid discharge barrel 124 is adhesively fixed between the second rotating plate 125 and the fixing plate 123. The liquid outlet of the liquid discharge barrel 124 is the liquid outlet of the liquid discharge assembly 12;

[0056] The principle of the liquid drainage component 12 is as follows: when the connecting rod 11 rotates, it drives the first rotating plate 121 and the second rotating plate 125 to rotate, squeezing the liquid outlet barrel 124 and expanding the liquid suction barrel 122, so that the cleaning liquid in the liquid outlet barrel 124 is discharged. The cleaning liquid enters the deep part of the ear canal through the hose 14 and the hard tube 5, and then enters the liquid suction barrel 122 from another hard tube 5 and another hose 14 to avoid excessive cleaning liquid.

[0057] In this embodiment, refer to the attached Figure 5 , the first transmission component 19 includes an arc-shaped protrusion 191, a top block 192, a first spring 193, an outer sleeve tube 194 and a second spring 195. The outer sleeve tube 194 is movably sleeved outside one end of the insertion rod 20 located in the main cylinder 8. A second spring 195 is fixed between the outer sleeve tube 194 and the insertion rod 20. A top block 192 is fixed at the other end of the outer sleeve tube 194. A first spring 193 is fixed between the top block 192 and the main cylinder 8. Arc-shaped protrusions 191 are fixedly arranged in a circular array on the side surface of the connecting rod 11. The side surface of the arc-shaped protrusion 191 is an arc surface, and the top block 192 moves on the arc surface of the arc-shaped protrusion 191;

[0058] The principle of the first transmission component 19 is as follows: the connecting rod 11 drives the arc-shaped protrusion 191 to rotate. The arc-shaped protrusion 191 pushes the top block 192, and the first spring 193 is compressed. The top block 192 pushes the outer sleeve tube 194, and the outer sleeve tube 194 pushes the insertion rod 20 through the second spring 195. When the connecting rod 11 rotates in the reverse direction, the arc-shaped protrusion 191 no longer pushes the top block 192, and the first spring 193 pushes the top block 192 back.

[0059] In this embodiment, refer to the attached Figure 4 and the attached Figure 5 , the second transmission component 21 includes a support frame 211, a third spring 212 and a linear protrusion 213. The support frames 211 are fixedly arranged in a circular array on the side surface of the connecting rod 11. The hard tube 5 is movably inserted in the support frame 211, and the hard tube 5 moves on the horizontal plane. A third spring 212 is fixed between the hard tube 5 and the support frame 211. The linear protrusion 213 is integrally formed on the inner side of the main cylinder 8. A linear curved surface is arranged on the side of the linear protrusion 213 close to the hard tube 5, and the hard tube 5 moves on the linear curved surface;

[0060] On the horizontal plane, the support frame 211 and the hard tube 5 are located between the linear protrusion 213 and the top block 192;

[0061] The principle of the second transmission component 21 is as follows: when the connecting rod 11 rotates, it drives the support frame 211 to rotate in a circle. The support frame 211 drives the hard tube 5 to rotate in a circle, and at the same time makes the hard tube 5 move on the linear curved surface, which makes the four hard tubes 5 gather together. When the connecting rod 11 rotates in the reverse direction, the third spring 212 pushes the hard tube 5 back.

[0062] The overall working principle of this device is as follows:

[0063] When it is necessary to expand the ear canal to observe the situation inside the ear canal, at this time, the liquid suction barrel 122 and the liquid discharge barrel 124 can not be placed into the main barrel 8 first. Rotate the rotary cylinder 3 in the forward direction. The rotary cylinder 3 drives the connecting rod 11 to rotate. The connecting rod 11 pushes out the insertion rod 20 through the first transmission assembly 19, so that the inner support piece 6 moves away from the main barrel 8, and then the inner support piece 6 expands the ear canal;

[0064] When it is necessary to spray and clean the inside of the ear canal, place the liquid suction barrel 122 and the liquid discharge barrel 124 into the main barrel 8, and insert the liquid inlet of the liquid suction barrel 122 and the liquid outlet of the liquid discharge barrel 124 into the hose 14. Rotate the rotary cylinder 3 in the reverse direction, so that the cleaning liquid in the liquid discharge barrel 124 is sprayed out to clean or treat the ear canal, and the excess cleaning liquid carrying dirt is sucked back into the liquid suction barrel 122;

[0065] When it is necessary to dry the inside of the ear canal, turn on the control switch 9 to make the first blower 17 and the second blower 18 work, blow air into the ear canal and suck the air flow to avoid discomfort to the patient caused by too high air pressure inside the ear canal;

[0066] When it is necessary to clamp dirt or sundries in the ear canal, rotate the rotary cylinder 3 in the reverse direction. The rotary cylinder 3 drives the connecting rod 11 to rotate, and drives the four rigid tubes 5 to approach each other through the second transmission assembly 21 to clamp the dirt or sundries.

[0067] It should be noted that when the rotary cylinder 3 is rotated in the forward direction, the inner support piece 6 can expand the ear canal, but at this time, the liquid discharge assembly 12 does not clean the ear canal, nor do the four rigid tubes 5 approach each other to clamp foreign objects or dirt. When the rotary cylinder 3 is rotated in the reverse direction, the four rigid tubes 5 can approach each other to clamp foreign objects or dirt. At this time, the inner support piece 6 just does not expand the ear canal, so that the foreign objects and dirt can be taken out smoothly, and the ear canal can be cleaned and treated after inserting the liquid suction barrel 122 and the liquid discharge barrel 124.

[0068] It should be noted that in the description of the present invention, the terms indicating directions or positional relationships such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings. This is only for convenience of description, rather than indicating or implying that the device or element must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation of the present invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0069] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and defined, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0070] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
