Description

Technical Field

[0001] The invention relates to the technical field of external auditory canal flushing, and in particular to an external auditory canal visual constant temperature flushing device. Background Art

[0002] The external auditory canal is a curved tube that extends from the external auditory meatus deep in the concha cavity to the tympanic membrane. It can transmit the sound waves collected by the auricle to the tympanic membrane. The direction is first inward and upward, then inward and upward, and then inward and downward. The outer side of the external auditory canal is based on the external auditory canal cartilage, and the inner side is based on the bone. The junction between the two is narrow, which has the function of preventing foreign objects from entering the external auditory canal and invading the tympanic membrane. The skin of the cartilaginous part of the external auditory canal has cerumen glands, which secrete light yellow and sticky cerumen. After drying in the air, the cerumen is in the form of thin flakes; some cerumen is like sticky grease, commonly known as oily ears. Earwax has the function of protecting the skin of the external auditory canal and adhering to foreign objects. Usually, earwax is discharged by itself with the help of chewing, opening the mouth and other movements.

[0003] External auditory canal flushing is intended to flush out broken and soft earwax, tiny foreign objects or softened earwax plugs that are difficult to remove from the deep part of the external auditory canal. In the prior art, external auditory canal flushers usually use a medical syringe to draw in anti-inflammatory water or medicine to flush the external auditory canal. The low-temperature flushing liquid can easily irritate the ear canal during flushing, causing discomfort to the patient. In addition, the location of foreign objects cannot be observed during flushing, resulting in the inability to control the impact direction of the water flow, which can easily irritate the eardrum.

[0004] In view of this, the present invention provides a visual constant temperature flusher for the external auditory canal to solve the technical problems existing in the above-mentioned prior art. Summary of the invention

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] Reference Figure 1-11A visual constant temperature flusher for an external auditory canal comprises a heating mechanism 1, a camera mechanism 2, a flow control mechanism 3, a residual liquid collecting mechanism 4, a flushing tube assembly 5, an elastic liquid supply mechanism 7 and a heating mechanism 1. A liquid storage bottle 9 is plugged into the interior of the heating mechanism 1, and an infusion tube 8 is connected between the liquid storage bottle 9 and the elastic liquid supply mechanism 7. A ring heater 14 and a temperature sensor close to the surface of the liquid storage bottle 9 are installed in the interior of the heating mechanism 1. The flow control mechanism 3 is sleeved on the outer side of the camera mechanism 2, and the front end of the flow control mechanism 3 is plug-in connected to the residual liquid collecting mechanism 4. The top of the elastic liquid supply mechanism 7 is sleeved on the rear end of the flow control mechanism 3, and the side of the elastic liquid supply mechanism 7 is connected to the inlet end of the flow control mechanism 3. The flushing tube assembly 5 is installed on the liquid outlet end of the flow control mechanism 3 by plugging and unplugging, and a protective cover 6 is screwed on the front end of the camera mechanism 2.

[0032] In the present invention, the liquid storage bottle 9 is inserted into the heating mechanism 1, and the annular heater 14 wrapped around the liquid storage bottle 9 is used to heat the flushing liquid and keep the flushing liquid at a constant temperature to avoid temperature difference stimulation between the flushing liquid and the external auditory canal when flushing the patient's external auditory canal. The camera mechanism 2, the flow control mechanism 3, the flushing tube assembly 5 and the elastic liquid supply mechanism 7 are assembled in sequence, and the elastic liquid supply mechanism 7 and the liquid storage bottle 9 are connected by the infusion tube 8. After that, the camera mechanism 2 is connected to a display screen or a mobile phone, and the elastic liquid supply mechanism 7 is held in the palm of the hand and pressed continuously to draw the flushing liquid in the liquid storage bottle 9. After that, the flow control mechanism 3 is pushed forward by the fingers to transport the flushing liquid in the elastic liquid supply mechanism 7 to the flushing tube assembly 5 to complete the flushing. The preparation work before washing is performed, and a residual liquid collection mechanism 4 that can be worn on the head is provided. After the residual liquid collection mechanism 4 is worn, the perforation on its surface is facing the external auditory canal. The camera mechanism 2 and the flushing tube assembly 5 are inserted into the patient's external auditory canal along the opening position of the residual liquid collection mechanism 4. The position of foreign matter and earwax plugs inside the patient's external auditory canal is observed through the camera mechanism 2. After that, the flow control mechanism 3 is pushed forward to open the valve of the elastic liquid supply mechanism 7 to the flushing tube assembly 5 and control the opening and closing size. The flushing flow rate and the extraction of flushing liquid are controlled by pressing the elastic liquid supply mechanism 7 by hand. The flushing liquid is flushed obliquely from the end of the flushing tube assembly 5 to the external auditory canal to avoid irritation to the tympanic membrane, and the oblique flushing avoids flushing foreign matter and earwax plugs into the deep part of the ear canal.

In the present invention, water is injected between the insulation sleeve 12 and the telescopic bag 13, and the amount of water in the telescopic bag 13 can be adjusted by plugging and unplugging the adjusting piston on the top of the syringe 15. When the liquid storage bottle 9 needs to be loaded, the adjusting piston is pulled upward to make the telescopic bag 13 shrink outward. After the liquid storage bottle 9 is loaded, the adjusting piston is pressed downward to expand the telescopic bag 13 toward the middle and quickly wrap the liquid storage bottle 9. It is suitable for the rapid loading and heating of existing physiological saline bottles, and maintains the stability of the heating of the liquid storage bottle 9 when the insulation sleeve 12 swings. In the flushing stage, a water bath is formed by the water temperature in the telescopic bag 13 to maintain the constant temperature of the liquid storage bottle 9.

[0035] As a further solution in the present invention, circular holes are provided on both sides of the insulation sleeve 12, and tension springs 16 are fixedly installed inside the circular holes, a U-shaped bracket 17 is installed between the two tension springs 16, and a C-shaped fixing buckle 18 is provided in the middle of the bracket 17. In the present invention, when the liquid storage bottle 9 is installed, the bracket 17 is pulled outward, and the fixing buckle 18 is sleeved on the bottle mouth of the liquid storage bottle 9. After the liquid storage bottle 9 is heated to the set temperature, the needle part of the infusion tube 8 is inserted into the interior of the liquid storage bottle 9, and the liquid storage bottle 9 is driven to an inclined position by a swing motor to facilitate the operation of drawing flushing liquid.

[0036] As a further solution in the present invention, the camera mechanism 2 includes a handle rod 21, and a high-definition camera 23 and a fill light are installed at the front end of the handle rod 21, and a wiring terminal 22 is screwed at the rear end of the handle rod 21. In the present invention, the camera mechanism 2 is a combined structure, which is easy to clean and install. At the same time, the flow control mechanism 3, the flushing pipe assembly 5 and the elastic liquid supply mechanism 7 are easy to hold and operate after installation.

[0037] As a further solution in the present invention, the flow control mechanism 3 includes a limiting sleeve 31 and a movable valve 32, and a connecting spring 35 is installed between the limiting sleeve 31 and the movable valve 32, and a connecting nozzle 36 cooperating with the flushing tube assembly 5 is provided at the front end position of the movable valve 32, and a support tube 33 cooperating with the residual liquid collection mechanism 4 is also provided at the front end position of the movable valve 32, and a U-shaped support member 34 is provided inside the support tube 33. In the present invention, the limiting sleeve 31 is held at the base of the hand during operation, so that the movable valve 32 and the flushing tube assembly 5 connected thereto can be pushed forward along the outside of the imaging mechanism 2, and the position of the flushing tube assembly 5 extending into the external auditory canal can be fine-tuned, and the operation is simple and convenient.

[0038] As a further solution in the present invention, the movable valve 32 includes a front valve cover 321 and a rear valve cover 322 which are rotatably connected to each other, and an annular valve cavity 324 is arranged in the middle of the front valve cover 321 and the rear valve cover 322, and the surfaces of the two annular valve cavities 324 are arranged with staggered fan-shaped grooves 325, and a torsion spring 323 is installed between the front valve cover 321 and the rear valve cover 322. In the present invention, the front valve cover 321 and the rear valve cover 322 are movably sealed and connected, and the two annular valve cavities 324 are connected through the staggered fan-shaped grooves 325. When in use, the rear valve cover 322 is pushed or rotated by fingers so that the front and rear fan-shaped grooves 325 overlap to realize the connection and flow regulation of the flushing liquid. In the absence of external force, the torsion spring 323 pulls the rear valve cover 322 to reset the seal, and the operation is simple and convenient.

[0039] As a further solution in the present invention, the elastic liquid supply mechanism 7 includes a fixed ring 73 sleeved on the outside of the limiting sleeve 31, and an elastic bag 71 arranged at the lower end of the fixed ring 73, one side of the elastic bag 71 is provided with a one-way valve 72 connected to the infusion tube 8, and the other side of the elastic bag 71 is provided with an insertion tube 74 connected to the movable valve 32. In the present invention, by pressing the elastic bag 71, the flushing liquid inside the elastic bag 71 can be squeezed into the movable valve 32. When the movable valve 32 is closed, the elastic bag 71 is reset and expanded to draw the flushing liquid in the liquid storage bottle 9, and holding the elastic bag 71 by hand can keep the flushing liquid in the bag warm, thereby further reducing the external auditory canal irritation caused by the temperature difference of the flushing liquid.

[0040] As a further solution in the present invention, the flushing tube assembly 5 includes a tube body 51 with an arc-shaped structure, and a soft head 52 with a Y-shaped structure is provided at the front end of the tube body 51, and a plurality of upper flushing holes 53 are provided on the upper side of the soft head 52, and a plurality of lower flushing holes 54 are provided on the lower side of the soft head 52.

When the soft head 52 with the Y-shaped structure contacts the wall of the external auditory canal, the soft head 52 is folded by force, thereby blocking the flushing hole on one side of the auditory canal wall. When the camera mechanism 2 observes the external auditory canal, the soft head 52 is folded by force. When there are foreign objects or earwax plugs in the ear canal, the foldable soft head 52 can be used to select the flushing position in a targeted manner. The soft head 52 can be folded toward the eardrum to guide the flushing liquid to flow toward the inside of the ear canal to fully wet the earwax plugs. The soft head 52 can be folded toward the external auditory canal to guide the flushing liquid to flow toward the outside of the ear canal, making it easier to flush out the foreign objects and earwax plugs. For earwax plugs adhered to the ear canal, the soft head 52 can be squeezed and rubbed to allow the earwax plugs to absorb the flushing liquid and soften, and the soft head 52 can be used to scrape the earwax plugs.
