Technical Field

[0001] This utility model belongs to the field of cleaning equipment technology, and in particular relates to an external auditory canal cleaning device. Background Technology

[0002] The external auditory canal, which connects the external auditory meatus to the tympanic membrane, is one of the most common sites of disease in the human body. Inflammation of the external auditory canal, such as otitis media and otitis externa, presents with a variety of clinical manifestations, including ear itching, ear discomfort, congestion, swelling, and watery discharge. When the inflammation is severe or the discharge blocks the ear canal, it can seriously affect the patient's hearing. Furthermore, due to the narrowness of the ear canal and the sensitivity of the tympanic membrane, cleaning and treating the external auditory canal requires precise and multifunctional instruments to ensure effective cleaning while protecting the tympanic membrane from damage.

[0003] Currently, when using external auditory canal cleaning instruments to clean the external auditory canal, some water will penetrate deep into the tympanic membrane, which can damage the tympanic membrane. In addition, during the cleaning process, the dirty water can easily run down the patient's face, staining the patient's clothes and causing discomfort. Utility Model Content

[0004] The purpose of this invention is to provide an external auditory canal cleaning device that seals the external auditory canal during cleaning, protecting the tympanic membrane while preventing contamination of the patient's clothing.

[0005] The external auditory canal cleaning device includes a liquid storage cylinder, a piston inside the liquid storage cylinder, a push rod connected to the piston, one end of the push rod extending out of the liquid storage cylinder and connected to a push-pull plate, a cleaning tube threadedly connected to the liquid storage cylinder, a plurality of water outlet holes for water jetting on the cleaning tube, a first air bladder on the liquid inlet end of the cleaning tube, a second air bladder on the liquid outlet end of the cleaning tube, a groove on the side wall of the cleaning tube, an air supply tube embedded in the groove, a compression air bladder on one end of the air supply tube, and a second air bladder connected to the second air bladder on the other end of the air supply tube, and a fixing tube connected to the first air bladder on the air supply tube.

[0006] Furthermore, a connecting block is fixed to the outer wall of the liquid storage cylinder, and a negative pressure suction device is installed on the side wall of the connecting block. Corresponding to the first airbag, there is an arc-shaped groove on the inner and outer walls of the cleaning tube. A drain groove is opened at the bottom of the arc-shaped groove, and a drain hole is opened at the bottom of the drain groove. An installation ring is installed in the drain hole, and the installation ring is connected to the negative pressure suction device through a drain pipe.

[0007] Furthermore, a limiting groove is provided on the top of the connecting block, and the liquid collection bottle of the negative pressure suction device is embedded in the limiting groove.

[0008] Furthermore, a limiting ring is provided in the limiting groove to limit the displacement of the liquid collecting bottle.

[0009] Furthermore, the first airbag has a funnel-shaped structure.

[0010] Furthermore, the mounting ring and the drain pipe are in an interference fit.

[0011] Furthermore, the limiting ring is made of silicone material.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention involves injecting cleaning fluid into a reservoir through its opening, then threading a cleaning tube to the opening of the reservoir. The cleaning tube is then inserted into the patient's external auditory canal. Pressing and squeezing the air bladder causes gas to flow through the gas delivery tube and the fixing tube into the first and second air bladders, causing them to inflate and seal the external auditory canal. Moving the push rod causes the piston to move, allowing the cleaning fluid to enter the cleaning tube and spray into the external auditory canal through several outlet holes for cleaning. The second air bladder seals the canal, preventing waste fluid from contacting the tympanic membrane and protecting the ear. The first air bladder prevents waste fluid from flowing out of the external auditory canal. By sealing the external auditory canal during cleaning, the tympanic membrane is protected while preventing soiling of the patient's clothing. Attached Figure Description

[0020] Example

[0021] The external auditory canal cleaning device described in this embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the device includes a storage cylinder 1, inside which is a piston 3. A push rod 2 is connected to the upper part of the piston 3. One end of the push rod 2 extends out of the storage cylinder 1 and is connected to a push-pull plate. A cleaning pipe 8 is threadedly connected to the storage cylinder 1 and communicates with it. The cleaning pipe 8 has several water outlet holes 9 for water jetting. A first air bladder 6 is provided at the liquid inlet end of the cleaning pipe 8, and a second air bladder 7 is provided at the liquid outlet end of the cleaning pipe 8. A groove is provided on the side wall of the cleaning pipe 8, and an air supply pipe 5 is embedded in the groove. One end of the air supply pipe 5 is connected to a compression air bladder 4, and the other end is connected to the second air bladder 7. A fixing pipe 16 is provided on the air supply pipe 5 to connect to the first air bladder 6. The opening of the storage cylinder 1 faces upward, and a push rod is attached to the bottom of the piston 3 inside the storage cylinder 1. 2. A through hole is provided at the bottom of the liquid storage cylinder 1. The lower end of the push rod 2 passes through the through hole and is connected to the push-pull plate. An internal thread is provided at the opening of the liquid storage cylinder 1. An external thread is provided on the outer wall of the liquid inlet end of the cleaning tube 8, which is threaded to the internal thread. The cleaning solution is injected into the liquid storage cylinder 1 through the opening of the liquid storage cylinder 1. The cleaning tube 8 is then installed at the opening of the liquid storage cylinder 1 through the threaded connection. The cleaning tube 8 and the liquid storage cylinder 1 can be disassembled for easy cleaning after use. Several water outlet holes 9 are provided on the side wall near the liquid outlet end of the cleaning tube 8. After the cleaning tube 8 is connected to the liquid storage cylinder 1, the liquid outlet end of the cleaning tube 8 is inserted into the patient's external auditory canal. The cleaning solution flows from the liquid storage cylinder 1 into the cleaning tube 8 and is finally sprayed out from the several water outlet holes 9 to clean the patient's external auditory canal.

[0022] A funnel-shaped first air bladder 6 is fitted onto the inlet end of the cleaning tube 8, and a ring-shaped second air bladder 7 is fitted onto the outlet end of the cleaning tube 8. A groove is formed on the outer wall of the cleaning tube 8, into which a gas delivery tube 5 is embedded. One end of the gas delivery tube 5 is connected to the second air bladder 7, and the other end is connected to a compression air bladder 4. A fixed tube 16 is provided on the gas delivery tube 5, and the fixed tube 16 is connected to the first air bladder 6. In use, pressing the compression air bladder 4 allows external gas to pass through the gas delivery tube 5 and the fixed tube 16 before entering the first air bladder. The first airbag 6 and the second airbag 7 are inflated inside the first airbag 6 and the second airbag 7. After the first airbag 6 and the second airbag 7 are inflated, they block the patient's external auditory canal. The cleaning solution sprayed from the several water outlet holes 9 on the cleaning tube 8 located between the first airbag 6 and the second airbag 7 cleans the external auditory canal. The second airbag 7 can prevent the cleaning solution from entering and contacting the tympanic membrane, thus protecting the ear. The first airbag 6 can prevent the cleaning solution from flowing out of the external auditory canal and dripping down the patient's face onto the patient's clothes, thus ensuring cleanliness and hygiene when cleaning the external auditory canal.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a connecting block 15 is fixed to the outer wall of the liquid storage cylinder 1. A negative pressure suction device 13 is installed on the side wall of the connecting block 15. Corresponding to the first airbag 6, there is an arc-shaped groove 17 on the inner and outer walls of the cleaning tube 8. A drain groove 18 is opened at the bottom of the arc-shaped groove 17. A drain hole is opened at the bottom of the drain groove 18. An installation ring 19 is installed in the drain hole. The installation ring 19 is connected to the negative pressure suction device 13 through a drain pipe 10. A connecting block 15 is welded or glued to the outer wall of the liquid storage cylinder 1. The regulator of the negative pressure suction device 13 is threadedly connected to the side wall of the connecting block 15. The regulator of 13 is connected to the collection bottle 11 via a connecting pipe 12. An arc-shaped groove 17 is provided on the outer wall of the cleaning pipe 8 near the storage cylinder 1. A drain groove 18 is provided at the bottom of the arc-shaped groove 17 and is connected to it. A drain hole is provided at the bottom of the drain groove 18. An installation ring 19 is welded or glued into the drain hole. One end of the drain pipe 10 is inserted into the installation ring 19. The other end of the drain pipe 10 is inserted into the fixing pipe of the top cover of the collection bottle 11. The cleaning pipe 8 is connected to the collection bottle 11 through the drain pipe 10. A negative pressure suction device 1 is installed on the side wall of the connecting block 15. 3. A power supply battery (not shown) is provided. The regulator of the negative pressure suction device 13 is activated. The regulator of the negative pressure suction device 13 is connected to the collection bottle 11 through the connecting pipe 12, so that the collection bottle 11 is in a negative pressure state. The second airbag 7 seals the waste liquid after cleaning. The waste liquid flows into the arc-shaped groove 17 at the second airbag 7 and into the drain groove 18. Finally, it flows into the drain pipe 10 through the drain hole and finally into the collection bottle 11 to collect the waste liquid. This prevents the waste liquid from dripping down the patient's cheeks onto clothing and contaminating the clothing, ensuring a dry environment during the cleaning of the external auditory canal. The connecting block 15 has a limiting groove at its top, and the collection bottle 11 of the negative pressure suction device 13 is embedded in the limiting groove. A limiting ring 14 is provided in the limiting groove to limit the displacement of the collection bottle 11. The collection bottle 11 is placed in the limiting groove at the top of the connecting block 15. The limiting ring 14 with a ring structure is attached in the limiting groove. The limiting ring 14 limits the position of the collection bottle 11 and prevents it from falling out of the limiting groove. The limiting ring 14 is made of silicone material. Silicone is soft and elastic and can squeeze and limit the side wall of the collection bottle 11 to make it more stable.

[0024] The mounting ring 19 and the drain tube 10 are press-fitted together. The inlet end of the drain tube 10 is press-fitted with the mounting ring 19. When it is necessary to clean the patient's external auditory canal, the inlet end of the drain tube 10 is inserted into the mounting ring 19, connecting the collection bottle 11 and the cleaning tube 8. This allows the waste liquid from cleaning the external auditory canal to pass through the arc-shaped groove 17 and the drain groove 18, and finally through the drain tube 10 into the collection bottle 11 for collection. This effectively prevents water from dripping onto the patient's face and staining their clothes during cleaning. After cleaning the external auditory canal, the drain tube 10 can be removed from the mounting ring 19, the waste liquid in the collection bottle 11 can be drained, and the cleaning tube 8, collection bottle 11, and drain tube 10 can be cleaned and disinfected for future use.

[0025] In actual use, when cleaning the external auditory canal, the cleaning solution is injected into the reservoir 1. The cleaning tube 8 is threaded to the opening of the reservoir 1. The patient's ear is pulled to make the ear canal a straight line, and the cleaning tube 8 is inserted into the patient's external auditory canal. The air bladder 4 is pressed to allow gas to enter the first air bladder 6 and the second air bladder 7 through the air supply tube 5 and the fixing tube 16, causing the first air bladder 6 and the second air bladder 7 to inflate and block the external auditory canal. Then, the push-pull plate is pressed to move the push rod 2. The push rod 2 moves the piston 3 in the reservoir 1, pushing the cleaning solution into the cleaning tube 8 and spraying it out from several water outlets 9 to clean the external auditory canal. During the cleaning process, the second air bladder 7 seals the waste liquid after cleaning to prevent it from flowing deep into the ear and contacting the tympanic membrane, which could cause damage to the tympanic membrane. After the second air bladder 7 inflates, it blocks the external auditory canal, preventing the waste liquid after cleaning from flowing from the ear to the patient's face or even dripping onto the patient's clothing and soiling the clothes.
