Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an ear canal exudate suction device. Background Art

[0002] The principle of treating otitis media is to remove middle ear fluid. Current treatments often involve puncturing the tympanic membrane and extracting the fluid, which is very harmful to the patient and can easily cause extreme discomfort. Referring to Chinese patent application number CN219230372U, a device for aspirating otitis media exudate is disclosed. The device utilizes a flexible tube molded from a soft thermoplastic elastomer and inserted into the ear canal. Through micropores in the tube, an absorbent material inserted into the tube rapidly absorbs otitis media exudate in the ear canal, achieving the goal of absorbing exudate without causing discomfort to the patient.

[0003] However, the adsorption material in the above device is completely filled inside the hose. Even if micropores are provided on the tube wall of the hose, due to the certain thickness of the hose, the adsorption material cannot directly contact with the exudate in the ear canal for absorption, resulting in poor absorption effect and difficulty in completely absorbing the exudate in the ear canal. Utility Model Content

[0004] The purpose of the present invention is to provide an ear canal exudate suction device with good absorption effect, which effectively solves the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above-mentioned purpose, the present utility model provides the following technical solutions.

[0006] An ear canal exudate suction device includes a conical hose and a liquid-absorbing sponge filling body. One end of the conical hose is a closed arc head, and the other end is an opening for the liquid-absorbing sponge filling body to enter and exit. A sealing cover is detachably installed on the open end of the conical hose for sealing. The shape of the liquid-absorbing sponge filling body is adapted to the interior of the conical hose. The liquid-absorbing sponge filling body is installed in the conical hose. A plurality of elongated grooves are arranged in a circular array around the axis of the conical hose on the tube wall. The liquid-absorbing sponge filling body is interference fit with the interior of the conical hose. The part of the liquid-absorbing sponge filling body corresponding to the position of the elongated groove extends through the elongated groove to the outside of the conical hose.

[0007] It can be seen that through the design of the interference fit between the liquid-absorbing sponge filling body and the inside of the conical hose, combined with the elastic deformation ability of the liquid-absorbing sponge filling body, the liquid-absorbing sponge filling body can partially extend through the elongated groove on the conical hose to the outside of the conical hose. When in use, the part of the liquid-absorbing sponge filling body exposed outside the conical hose can directly contact the inner wall of the ear canal and the exudate, thereby improving the absorption effect of the exudate. At the same time, by rotating the device in the ear canal, it is ensured that the exposed part of the liquid-absorbing sponge filling body is sufficient to cover most areas in the ear canal, avoiding the existence of dead corners in liquid absorption, thereby ensuring that the exudate in the ear canal is sucked out as much as possible.

[0008] Furthermore, a supporting core rod is inserted into the liquid-absorbing sponge filling body, and the supporting core rod passes through the liquid-absorbing sponge filling body. The liquid-absorbing sponge filling body and the supporting core rod are fixed, and the liquid-absorbing sponge filling body and the supporting core rod are detachable and replaceable.

[0009] Furthermore, the open end of the conical hose is provided with an external thread, the blocking cover is provided with an internal thread, and the blocking cover is threadably mounted on the open end of the conical hose.

[0010] Furthermore, a positioning hole A is provided on the inner end wall of the conical hose for matching and inserting one end of the supporting core rod, and a positioning hole B is provided on the inner end wall of the sealing cover for matching and inserting the other end of the supporting core rod. When the whole is assembled, one end of the supporting core rod is positioned and inserted in the positioning hole A, and the other end is positioned and inserted in the positioning hole B.

[0011] Furthermore, a ring-shaped part is fixed to the tail of the blocking cover, and the ring-shaped part is made of hard plastic.

[0012] Furthermore, the liquid-absorbing sponge filling body is made of medical sponge material, and the conical hose is made of TPU material.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0014] 1. The present invention adopts the design of interference fit between the liquid-absorbing sponge filling body and the inside of the conical hose, combined with the elastic deformation ability of the liquid-absorbing sponge filling body, so that the liquid-absorbing sponge filling body partially passes through the elongated groove on the conical hose and extends to the outside of the conical hose. When in use, the part of the liquid-absorbing sponge filling body exposed outside the conical hose can directly contact the inner wall of the ear canal and the exudate, thereby improving the absorption effect of the exudate. At the same time, by rotating the device in the ear canal, it is ensured that the exposed part of the liquid-absorbing sponge filling body is sufficient to cover most areas in the ear canal, avoiding the existence of dead corners for liquid absorption, thereby ensuring that the exudate in the ear canal is absorbed as much as possible.

[0015] 2. The utility model installs a supporting core rod in the liquid-absorbing sponge filling body. When the liquid-absorbing sponge filling body is inserted into the conical hose, the supporting and guiding effect provided by the supporting core rod can ensure that the liquid-absorbing sponge filling body can be filled in the conical hose, avoiding twisting and jamming of the liquid-absorbing sponge filling body when inserted into the conical hose due to its softness. In addition, the supporting core rod is positioned in the conical hose by using the positioning holes A and the positioning holes B to provide stable support, avoiding deformation or retreat of the liquid-absorbing sponge filling body due to friction with the ear canal when inserted into the ear canal, thereby ensuring that the state of the liquid-absorbing sponge filling body is maintained.

[0016] 3. The utility model designs the conical hose as a reusable component that is easy to clean, and sets the liquid-absorbing sponge filling body and the supporting core rod as disposable consumables. After use, the conical hose does not need to be discarded, thereby reducing the cost of use. At the same time, the plug-in installation method of the liquid-absorbing sponge filling body and the supporting core rod combined with the detachable effect of the sealing cover makes it easy to disassemble and replace the liquid-absorbing sponge filling body and the supporting core rod.

[0017] 4. The utility model provides a ring-shaped part at the tail of the blocking cover. When removing the device from the ear canal, the ring-shaped part can be clamped with tweezers to conveniently pull the device out of the ear canal. The ring-shaped part is made of hard plastic, has high structural strength, and is not easy to deform, thereby preventing the device from being deformed and separated from the tweezers when being pulled out of the ear canal. At the same time, by pinching the ring-shaped part, it is convenient to exert force to twist and disassemble the blocking cover, thus killing two birds with one stone.

[0028] See also Figures 1-6 The utility model provides an ear canal exudate suction device, comprising a conical hose 1 and a liquid-absorbing sponge filling body 3. One end of the conical hose 1 is a closed arc head 11, and the other end is an opening for the liquid-absorbing sponge filling body 3 to enter and exit. The open end of the conical hose 1 is detachably installed with a sealing cover 4 for sealing. The shape of the liquid-absorbing sponge filling body 3 is adapted to the interior of the conical hose 1. The liquid-absorbing sponge filling body 3 is installed in the conical hose 1. A plurality of elongated grooves 2 are arranged in a circular array around the axis of the tube wall of the conical hose 1. The liquid-absorbing sponge filling body 3 is interference fit with the interior of the conical hose 1, and the part of the liquid-absorbing sponge filling body 3 corresponding to the position of the elongated groove 2 passes through the elongated groove 2 and extends to the outside of the conical hose 1.

[0029] When the present ear canal exudate suction device is in use, the absorbent sponge filling body 3 is loaded into the conical hose 1 from the open end of the conical hose 1, and the sealing cap 4 is installed on the open end of the conical hose 1 to seal it and prevent the absorbent sponge filling body 3 from falling out of the conical hose 1. Due to the interference fit between the absorbent sponge filling body 3 and the inside of the conical hose 1, combined with the elastic deformation ability of the absorbent sponge filling body 3, the absorbent sponge filling body 3 will pass through the elongated groove 2 on the conical hose 1 and extend to the outside of the conical hose 1. After the entire device is inserted into the ear canal, the part of the absorbent sponge filling body 3 exposed outside the conical hose 1 can directly contact the inner wall of the ear canal and the exudate, thereby improving the absorption effect of the exudate. At the same time, by rotating the device in the ear canal, it is ensured that the exposed part of the absorbent sponge filling body 3 is sufficient to cover most areas in the ear canal, avoiding the existence of dead corners for suction, thereby ensuring that the exudate in the ear canal is sucked out as much as possible.

[0030] In addition, the head of the conical hose 1 is set as an arc head 11, which is convenient for inserting into the ear canal and also avoids causing damage to the inner wall of the ear canal.

[0031] Specifically, a support core rod 5 is inserted into the liquid absorbent sponge filling body 3, and the support core rod 5 passes through the liquid absorbent sponge filling body 3. The liquid absorbent sponge filling body 3 is fixed to the support core rod 5. The liquid absorbent sponge filling body 3 and the support core rod 5 are detachable and replaceable. By adding the support core rod 5 into the liquid absorbent sponge filling body 3, when the liquid absorbent sponge filling body 3 is inserted into the conical hose 1, the support and guiding effect provided by the support core rod 5 can ensure that the liquid absorbent sponge filling body 3 can be filled in the conical hose 1, thereby avoiding twisting and jamming of the liquid absorbent sponge filling body 3 when it is inserted into the conical hose 1 due to its softness.

[0032] Specifically, the open end of the conical hose 1 is provided with an external thread, and the sealing cover 4 is provided with an internal thread. The sealing cover 4 is threadedly installed on the open end of the conical hose 1. The sealing cover 4 is detachable by the threaded installation method.

[0033] In addition, the conical hose 1 is made of TPU material, which is soft and skin-friendly and will not cause excessive stimulation to the ear canal. At the same time, the conical hose 1 made of TPU material is easy to clean for reuse, and the liquid-absorbing sponge filling body 3 is made of medical sponge material and has a good liquid-absorbing effect.

[0034] The conical hose 1 is designed as a reusable component that is easy to clean, and the liquid-absorbing sponge filling body 3 and the supporting core rod 5 are set as disposable consumables. After use, the conical hose 1 does not need to be discarded, thereby reducing the cost of use. At the same time, the inserted installation method of the liquid-absorbing sponge filling body 3 and the supporting core rod 5 combined with the detachable effect of the sealing cover 4 makes it easy to disassemble and replace the liquid-absorbing sponge filling body 3 and the supporting core rod 5.

[0035] Specifically, a positioning hole A12 is provided on the inner end wall of the conical hose 1 for matching insertion of one end of the supporting core rod 5, and a positioning hole B41 is provided on the inner end wall of the sealing cover 4 for matching insertion of the other end of the supporting core rod 5. When the whole is assembled, one end of the supporting core rod 5 is positioned and inserted in the positioning hole A12, and the other end is positioned and inserted in the positioning hole B41. The positioning hole A12 and the positioning hole B41 are used to position the supporting core rod 5 in the conical hose 1, which provides stable support and prevents the liquid-absorbing sponge filling body 3 from being deformed or retreated due to friction with the ear canal when inserted into the ear canal, thereby ensuring that the state of the liquid-absorbing sponge filling body 3 is maintained.

[0036] Specifically, a ring-shaped part 42 is fixed to the tail of the blocking cover 4. When removing the device from the ear canal, the ring-shaped part 42 can be clamped with tweezers to conveniently pull the device out of the ear canal. The ring-shaped part 42 is made of hard plastic, has a high structural strength, and is not easy to deform, thereby avoiding deformation and separation from the tweezers when the device is pulled out of the ear canal. At the same time, by pinching the ring-shaped part 42, it is convenient to exert force to twist and disassemble the blocking cover 4, thus killing two birds with one stone.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
