Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a medical ear canal cleaner. Background Technology

[0002] In the medical field, ear canal cleaning is an important means of treating various ear canal diseases (such as cerumen impaction and external otitis) and for daily ear canal cleaning and maintenance. Currently, medical ear canal cleaners on the market are mainly divided into two types: manual and electric. Manual ear canal cleaners typically consist of a syringe, a connecting tubing, and a flushing head. Medical personnel manually push the syringe plunger to inject the cleaning solution into the ear canal through the tubing and flushing head.

[0003] Chinese Patent Publication No. CN222075626U discloses a medical ear canal cleaner, including a reservoir and a collection mechanism. A flushing mechanism is inserted and connected to the right side of the reservoir's outer surface. The reservoir includes a reservoir tube and a fixing rod. A finger plate is fixedly connected to the left side of the reservoir tube's outer surface, and a connector is fixedly connected to the middle of the right end of the reservoir tube. A rubber plug is fixedly connected to the right end of the fixing rod. This medical ear canal cleaner features multiple outlet holes at the distal end of the flushing tube in the flushing mechanism, all of which are angled. During use, by controlling the reservoir to allow the flushing fluid to flow out through these outlet holes, the angled outlet holes allow the cleaning fluid to flush towards the outer wall of the ear canal, ensuring the fluid flows directly outwards without contacting the patient's eardrum. This reduces patient discomfort and prevents hearing loss caused by water on the eardrum.

[0004] In the existing technology, during the use of a medical ear canal cleaner, the cleaning fluid is simply allowed to flow out naturally to remove dirt, which can easily lead to some waste fluid remaining in the ear canal. This not only affects the cleaning effect but also poses a risk of secondary pollution. Therefore, we have made improvements to this and proposed a medical ear canal cleaner. Utility Model Content

[0005] The purpose of this invention is to address the problem that some waste liquid may remain in the ear canal during the use of a current medical ear canal cleaner, where the rinsing solution naturally flows out to remove dirt.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] A medical ear canal cleaner uses auxiliary gears of different diameters to achieve rapid infusion into the infusion chamber and slow, thorough retrieval into the recovery chamber, effectively improving cleaning efficiency and addressing the aforementioned problems.

The two threaded rods are inserted into the interiors of the two pistons and are threadedly connected to them.

[0011] As a preferred technical solution of this application, the connection structure includes insert blocks, both of which are fixedly connected to the flushing head. Both insert blocks are inserted into the interior of the base and slidably connected thereto. The interior of the base is rotatably connected to a worm, a worm wheel, and a double-acting screw. The worm and the worm wheel mesh with each other. The worm wheel is fixedly connected to the double-acting screw. The outer side of the double-acting screw is threaded with two sliding plates. Two insert rods are fixedly installed on the side of the two sliding plates that are close to each other. Both sliding plates and insert rods are slidably connected to the base. The insert rods pass through the insert blocks and are slidably connected thereto.

[0012] As a preferred technical solution of this application, a handle is fixedly installed on one side of the worm gear, and the handle passes through one side of the base and is rotatably connected to it. Two fixed rods are fixedly installed inside the base, and the two fixed rods pass through two slide plates respectively and are slidably connected to them.

[0013] As a preferred technical solution of this application, each of the two pistons is fixedly installed with a plate on the side near the outer cylinder. The two plates are respectively inserted into the interior of the two outer cylinders and slidably connected thereto. Multiple electromagnets are embedded on the side of the two outer cylinders and pistons that are close to each other, and adjacent electromagnets are magnetically connected.

[0014] As a preferred technical solution of this application, a side plate is provided on one side of each of the two cylinders, and the two side plates are slidably connected to the base. Two short rods are fixedly installed on the side of each of the two side plates near the cylinder, and the short rods are inserted into the inside of the cylinder and slidably connected to it. Permanent magnets are embedded on the side of the base and the two side plates that are close to each other, and two adjacent permanent magnets are magnetically connected.

[0015] As a preferred technical solution of this application, transparent windows are provided on both sides of the two cylinders and on both sides of the side plate.

[0016] As a preferred technical solution of this application, a handle is fixedly installed at the bottom of the base, a rubber pad is embedded on the outside of the handle, and multiple control buttons are provided on one side of the handle. The multiple control buttons are electrically connected to the first servo motor, the battery, the display screen, the pressure sensor and the flow monitor.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In the scheme of this application:

[0019] (1) The auxiliary gear and threaded rod are driven to rotate by the first servo motor, which in turn drives the piston to move in the cylinder to achieve precise delivery of cleaning fluid and waste liquid recycling. The diameter of the auxiliary gear on the infusion chamber side is smaller than that of the auxiliary gear on the recycling chamber side, so that at the same speed, the piston in the infusion chamber moves faster and can quickly inject the cleaning fluid into the ear canal, while the piston in the recycling chamber moves relatively slower, ensuring that the waste liquid is fully recycled and improving cleaning efficiency and effect.

[0020] (2) By cooperating with the worm, worm wheel and double screw in the connecting structure, the worm is rotated by turning the hand, and the double screw is rotated by the worm wheel, which in turn drives the slide plate and the insertion rod to move, so as to realize the firm connection and convenient disassembly of the flushing head and the base, and facilitate the cleaning and replacement of the flushing head.

[0034] Example 1: Please refer to the appendix of the instruction manual. Figure 1-2 A medical ear canal cleaner includes a base 1, a flushing head 2 on one side of the base 1, two cylinders 3 inside the base 1, an infusion chamber 4 and a recovery chamber 5 on the flushing head 2, the infusion chamber 4 and the recovery chamber 5 being connected to the two cylinders 3 respectively, an inclined through-hole plate being fixedly installed on one side of the flushing head 2 inside the infusion chamber 4, and multiple water inlets being opened at the bottom of the flushing head 2 outside the recovery chamber 5, all of which are connected to the recovery chamber 5, a piston 10 being installed inside each of the two cylinders 3, the piston 10 passing through one side of the cylinder 3 and being slidably connected thereto, an outer cylinder 9 being installed on one side of each of the two pistons 10, the two outer cylinders 9 and the pistons 10 being slidably connected to the base 1, a connecting structure being provided on the base 1, and protrusions being fixedly installed on the outer sides of each of the two pistons 10, the protrusions being inserted into the cylinders 3 and being slidably connected thereto.

[0035] In this embodiment of the utility model, the operator starts the first servo motor 6 by controlling the button 22 on the handle 12. The first servo motor 6 drives the auxiliary gear 7 connected to it to rotate. Since the two auxiliary gears 7 mesh with each other, they drive the other auxiliary gear 7 to rotate. The two auxiliary gears 7 drive their respective threaded rods 8 to rotate. The threaded rods 8 are threadedly connected to the outer cylinder 9 and the piston 10, so that the outer cylinder 9 and the piston 10 slide in the base 1. The auxiliary gear 7 on the infusion chamber 4 side has a small diameter. When it rotates, it drives the threaded rod 8 to move the piston 10 quickly, so that the cleaning fluid in the cylinder 3 is quickly injected into the ear canal through the infusion chamber 4 and the flushing head 2. The auxiliary gear 7 on the recovery chamber 5 side has a large diameter. The piston 10 it drives moves more slowly, so that the waste fluid in the ear canal is sucked into the cylinder 3 through the water inlet of the recovery chamber 5, thus completing the process of cleaning fluid delivery and waste fluid recovery.

[0036] In this embodiment of the invention, the inclined through-hole plate of the infusion chamber 4 inside the flushing head 2 allows the cleaning fluid to be sprayed out at a specific angle, enhancing the flushing force on the inner wall of the ear canal; the water inlet design on the outside of the recovery chamber 5 can effectively recover waste liquid from multiple directions, avoiding residue.

[0037] Example 2: Please refer to the appendix of the instruction manual. Figure 1-5 In a preferred embodiment of this utility model, a first servo motor 6 is fixedly installed inside the base 1. Two auxiliary gears 7 are rotatably connected inside the base 1. The output end of the first servo motor 6 is fixedly connected to one of the auxiliary gears 7. Threaded rods 8 are fixedly installed on one side of each of the two auxiliary gears 7. Both threaded rods 8 are rotatably connected to the base 1. The two threaded rods 8 pass through the two outer cylinders 9 and are threadedly connected to them. The two threaded rods 8 are inserted into the interiors of the two pistons 10 and are threadedly connected to them. The diameter of the auxiliary gear 7 on the infusion chamber 4 side is smaller than the diameter of the auxiliary gear 7 on the recovery chamber 5 side.

[0038] The connecting structure includes two insert blocks 13, both of which are fixedly connected to the flushing head 2. Both insert blocks 13 are inserted into the base 1 and slidably connected thereto. The base 1 is rotatably connected to a worm 16, a worm wheel 17, and a double-acting screw 18. The worm 16 and the worm wheel 17 mesh, and the worm wheel 17 is fixedly connected to the double-acting screw 18. The outer side of the double-acting screw 18 is threaded with two sliding plates 14. Two insert rods 15 are fixedly installed on the side of the two sliding plates 14 that are close to each other. Both sliding plates 14 and insert rods 15 are slidably connected to the base 1. The insert rods 15 pass through the insert blocks 13 and are slidably connected thereto.

[0039] A handle is fixedly installed on one side of the worm gear 16, and the handle passes through one side of the base 1 and is rotatably connected to it. Two fixed rods 19 are fixedly installed inside the base 1, and the two fixed rods 19 pass through the two slide plates 14 respectively and are slidably connected to them.

[0040] Each of the two pistons 10 has a fixed insert plate 11 on the side near the outer cylinder 9. The two insert plates 11 are inserted into the interior of the two outer cylinders 9 and slidably connected to them. Multiple electromagnets are embedded on the side of the two outer cylinders 9 and the pistons 10 that are close to each other, and adjacent electromagnets are magnetically connected.

[0041] Each of the two cylinders 3 has a side plate 20 on one side. Both side plates 20 are slidably connected to the base 1. Two short rods are fixedly installed on the side of each side plate 20 near the cylinder 3. The short rods are inserted into the inside of the cylinder 3 and slidably connected to it. Permanent magnets are embedded on the side of the base 1 and the two side plates 20 that are close to each other. Adjacent permanent magnets are magnetically connected.

[0042] Transparent windows are provided on both sides of the two cylinders 3 and on both sides of the side plate 20. A flow monitor is embedded inside the flushing head 2 and at the bottom of the infusion chamber 4. Pressure sensors are embedded inside the base 1 and on the corresponding sides of the flushing head 2. Rubber pads are fixedly installed on one side of the inner wall of the base 1 and on one side of the two cylinders 3. Multiple rubber rings are provided on the outer side of the flushing head 2.

[0043] A handle 12 is fixedly installed at the bottom of the base 1. A rubber pad is embedded on the outside of the handle 12. Multiple control buttons 22 are provided on one side of the handle 12. The multiple control buttons 22 are electrically connected to the first servo motor 6, the battery 21, the display screen, the pressure sensor and the flow monitor.

[0044] In this embodiment of the utility model, when installing the flushing head 2, the insert block 13 on the flushing head 2 is inserted into the base 1. The handle on the worm gear 16 is rotated, and the worm gear 16 drives the worm wheel 17 to rotate. The worm wheel 17 causes the double-sided lead screw 18 to rotate. The two sliding plates 14 on the double-sided lead screw 18 drive the insert rod 15 to move towards the middle. The insert rod 15 passes through the insert block 13, thus achieving a firm connection between the flushing head 2 and the base 1. When disassembling, the handle is rotated in the opposite direction, and the insert rod 15 moves outward, so the flushing head 2 can be removed.

[0045] After long-term use of the equipment, dirt may remain inside the cylinder 3 or parts may be worn out, requiring disassembly, cleaning or replacement. Disconnecting the power supply to the electromagnet will cause the magnetic connection to fail, making it easy to pull the piston 10 out of the outer cylinder 9, thereby enabling the disassembly of the two cylinders 3.

[0046] The side plate 20 of the cylinder 3 is magnetically connected to the base 1 by a permanent magnet. With the sliding of the short rod, the connection is stable while facilitating the disassembly and maintenance of the cylinder 3. A sealing ring can also be installed at the side plate 20 to further improve the sealing performance.

[0047] The transparent window on the cylinder 3 facilitates observation of the internal liquid condition. The flow monitor and pressure sensor monitor the infusion flow and pressure in real time. The control button 22 and the display screen enable precise control and parameter display of the equipment, improving the convenience and safety of operation. At the same time, the battery 21 is electrically connected to the equipment on the device to provide it with power.

[0048] A sealing ring is installed at the connection between the base 1 and the flushing head 2 to prevent the cleaning fluid from leaking from the junction of the two, ensuring that the cleaning fluid can only flow through the infusion chamber 4 and the recovery chamber 5; rubber pads are installed at the sliding connection between the outer cylinder 9, the piston 10 and the base 1 and the cylinder 3 to prevent liquid from seeping out from their gaps, which would affect the normal operation and safety of the equipment.

[0049] Example 3: Please refer to the appendix of the instruction manual. Figure 2 and Figure 6 In a preferred embodiment of this utility model, a second servo motor is fixedly installed inside the rinsing head 2. A gear ring and multiple drive gears are rotatably connected inside the rinsing head 2. The gear ring meshes with the multiple drive gears. The output end of the second servo motor is fixedly connected to one of the drive gears. Two bevel gears are provided on one side of each of the multiple drive gears. Adjacent bevel gears mesh. One bevel gear is fixedly connected to the drive gear. An adjusting rod is fixedly installed on one side of the other bevel gear. A bracket structure is provided on the outer side of each of the multiple adjusting rods. The bracket structure consists of two fixed seats and a rotating shaft fixedly connected. The adjusting rod passes through one of the fixed seats and is threaded to it. A cleaning brush is rotatably connected to the outer side of each of the multiple rotating shafts. A guide rod is provided inside each of the multiple other fixed seats. The multiple guide rods are fixedly connected to the rinsing head 2 and pass through the other fixed seat and are slidably connected to it. A T-shaped limiting rod is provided on the side of each of the multiple guide rods away from the rinsing head 2. The T-shaped limiting rod is inserted into the guide rod and threaded to it.

[0050] In this embodiment of the utility model, according to the patient's ear canal condition, the second servo motor inside the rinsing head 2 is activated by the control button 22. The second servo motor drives the drive gear to rotate, and the drive gear meshes with the gear ring. At the same time, the drive gear drives the adjusting rod to rotate through the bevel gear. The adjusting rod is threadedly connected to the fixed seat in the bracket structure. Rotating the adjusting rod can adjust the position of the fixed seat, thereby driving the cleaning brush to adjust its position, so that multiple cleaning brushes move from inside the rinsing head 2 to clean the ear canal. At the same time, the position of another fixed seat is restricted by the T-shaped limiting rod. By operating the T-shaped limiting rod, it is easy to disassemble and replace the bracket and the cleaning brush.

[0051] In this embodiment of the utility model, waterproof sealant is applied to the threaded hole of one of the fixing seats. The sealant forms a sealing layer between the threads, which can prevent liquid from seeping in without affecting the normal rotation and adjustment of the adjusting rod. A sealing ring is set at one end of the adjusting rod and the guide rod that are inserted into the flushing head 2 to further enhance the sealing effect.

[0052] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
