Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an external hearing aid. Background Technology

[0002] External hearing aids are electronic products commonly used by people with hearing loss. They process sound signals to allow patients to hear sounds that they could not hear or could not hear clearly before.

[0003] Currently in clinical practice, when treating elderly patients with hearing loss, a large proportion of them do not have hearing aids, which makes it very inconvenient for them to communicate with medical staff after hospitalization. Many medical histories are described by family members, which may result in unclear statements from family members, making it difficult for medical staff to accurately and directly understand the patient's condition.

[0004] To address this situation, some healthcare professionals typically choose to temporarily provide hearing aids to patients when communicating with them, aiming to improve the patient's hearing and enhance the accuracy and efficiency of communication. However, when healthcare professionals communicate with multiple hearing-impaired patients, the hearing aids usually need to be worn on different patients' ears. To avoid cross-infection, healthcare professionals often disinfect the hearing aid earplugs with alcohol. However, frequent use of alcohol for disinfection can damage the silicone molecular chain structure due to its organic solvent nature, causing the earplugs to swell, become sticky, or lose elasticity, thus damaging the hearing aids. This can lead to deformation of the earplugs, resulting in decreased sealing and making it difficult for the earplugs to be securely fastened to the hearing aid's sound tube.

[0005] Therefore, how to prevent cross-infection and damage to hearing aids when they are worn by multiple patients is a technical problem that urgently needs to be solved. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings encountered when communicating with multiple hearing-impaired patients, and to provide an external hearing aid that avoids cross-infection and damage to the hearing aid when it is worn by multiple patients.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] An external hearing aid includes an earplug with an inner wall and an outer wall. The inner wall has a cylindrical structure, the outer wall is located on the outside of the earplug, and the inner wall is located on the inside of the earplug. A receiving cavity is provided inside the earplug, and a first annular opening is provided on the inner wall. The receiving cavity is used to place a plug sleeve, which extends from the first opening and fits onto the outer wall.

[0009] As the preferred technical solution of this application, the portion of the plug sleeve that does not extend from the first opening is rolled up, and when the plug sleeve is in the unfolded state, the plug sleeve has a cylindrical structure.

[0010] As the preferred technical solution of this application, the plug sleeve is elastic, and the portion of the plug sleeve that fits onto the outer plug wall is in a stretched state.

[0011] As the preferred technical solution of this application, the earplug includes a first plug body and a second plug body, the first plug body and the second plug body are detachably connected, when the first plug body and the second plug body are connected, the first plug body and the second plug body cooperate to form a receiving cavity; when the first plug body and the second plug body are separated, the receiving cavity is open.

[0012] As the preferred technical solution of this application, the first plug and the second plug are connected by a threaded connection.

[0013] As the preferred technical solution of this application, the second plug body includes a plug body part and a plug body part, the plug body part and the plug body part are slidably engaged, so that the plug body part can move relative to the plug body part along the central axis direction of the plug body part, and the plug body part is connected to the first plug body;

[0014] An elastic element is connected between the first plug body and the second plug body. The elastic element provides an initial tension to put the second plug body in an initial state. When the second plug body is in the initial state, the portion of the plug sleeve located at the first opening is clamped by the first plug body and the first plug body.

[0015] When the first part of the plug body moves away from the second part of the plug body relative to the first plug body, the width of the first opening gradually increases, which allows the first plug body and the first part of the plug body to release the clamping of the plug sleeve.

[0016] As the preferred technical solution of this application, the first plug body is provided with a first channel, and a push rod is provided in the first channel. The push rod is used to abut against a part of the plug body to push the part of the plug body to move relative to the second part of the plug body, so as to change the width of the first opening.

[0017] As a preferred technical solution of this application, the first plug body is further provided with a retaining ring, which is used to fix the plug sleeve fitted on the first plug body. The retaining ring is an open-loop structure that can be elastically bent so that the retaining ring is detachable.

[0018] As the preferred technical solution of this application, the retaining ring is provided with a cutting blade, and the first plug body is provided with a groove. The groove is adapted to the cutting blade. When the retaining ring is installed on the first plug body, the cutting blade extends into the groove. By causing the retaining ring to rotate relative to the first plug body in the direction of the central axis of the first plug body, the cutting blade cuts the plug sleeve.

[0019] As a preferred technical solution of this application, it also includes a sound column, which is connected to a first plug and the first plug is sleeved on the outer wall of the sound column.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. In the solution of this application, by setting a plug sleeve, the plug sleeve placed in the receiving cavity can extend out from the first opening, and the part of the plug sleeve extending out of the first opening can cover the outer wall of the plug sleeve, thereby protecting the outer wall of the plug sleeve. When the patient wears the earplug, the patient's ear canal comes into contact with the plug sleeve covering the outer wall of the plug sleeve, which can prevent the patient's ear canal from directly contacting the outer wall of the plug sleeve. After the patient has finished using the earplug and before the next patient uses it, the plug sleeve can be pulled to extend out of the first opening again, thereby removing the plug sleeve part that has come into contact with the previous patient from the outer wall of the plug sleeve, so that the unused part of the plug sleeve covers the outer wall of the plug sleeve for subsequent patients to use, thereby avoiding the risk of cross-infection. Moreover, since there is no alcohol disinfection, damage to the hearing aid can be avoided, thereby improving the service life of the hearing aid.

[0022] 2. Furthermore, the portion of the plug sleeve that does not extend from the first opening is rolled up, which makes it easier for the receiving cavity to accommodate the plug sleeve. When the plug sleeve is pulled, it is gradually unfolded, and the un-unfolded portion of the plug sleeve is rolled up, which can reduce the risk of contamination of the unused portion of the plug sleeve. At the same time, when the plug sleeve has a cylindrical structure, it is more conducive to the plug sleeve providing comprehensive protection to the outer plug wall.

[0023] 3. Furthermore, by setting a plug body part one, a plug body part two, and an elastic element, the elastic element provides an initial tension to put the second plug body in an initial state. At this time, the portion of the plug sleeve located at the first opening is clamped by the first plug body and the plug body part one, which can reduce the probability of pulling the plug sleeve out of the receiving cavity and improve the stability of the position of the plug sleeve on the outer plug wall. Specifically, one side of the first plug body forms one side wall of the first opening, and one side of the second plug body forms the other side wall of the first opening. Then, when it is necessary to cover the outer plug wall with a new plug sleeve, by moving the plug body part one away from the first plug body relative to the plug body part two, the width of the first opening is gradually increased, and the first plug body and the plug body part one release the clamping of the plug sleeve. In this state, the plug sleeve can be pulled so that a new plug sleeve can be covered on the outer plug wall. After the new plug sleeve is covered on the outer plug wall, when the external force is released, the elastic element restores its deformation, so that the second plug body returns to the initial state, and the first plug body and the plug body part one clamp the plug sleeve again.

[0024] 4. Furthermore, by setting a cutting blade on the retaining ring and a groove on the first plug body, when the retaining ring is installed on the first plug body, the cutting blade extends into the groove. By causing the retaining ring to rotate relative to the first plug body in the direction of the central axis of the first plug body, the cutting blade can cut the plug sleeve, thereby facilitating the separation of the used part on the plug sleeve from the unused part on the plug sleeve, further reducing the risk of cross-infection.

[0036] Example 1: This example provides an external hearing aid, see [link to example]. Figures 1-5As shown, the device includes an earplug 1, which has an inner wall 2 and an outer wall 3. The inner wall 2 has a cylindrical structure, the outer wall 3 is located on the outside of the earplug 1, and the inner wall 2 is located on the inside of the earplug 1. The earplug 1 has a receiving cavity 4, and the inner wall 2 has a first annular opening 5. The receiving cavity 4 is used to place a plug sleeve 6, which extends from the first opening 5 and fits onto the outer wall 3.

[0037] In this application, by setting a plug sleeve 6, the plug sleeve 6 placed in the receiving cavity 4 can extend out from the first opening 5, and the part of the plug sleeve 6 extending out of the first opening 5 can cover the outer plug wall 3, thereby protecting the outer plug wall 3. When the patient wears the earplug 1, the patient's ear canal comes into contact with the plug sleeve 6 covering the outer plug wall 3, which can prevent the patient's ear canal from directly contacting the outer plug wall 3. After the patient finishes using the earplug 1 and before the next patient uses it, the plug sleeve 6 can be pulled to extend out of the first opening 5 again, thereby removing the part of the plug sleeve 6 that has come into contact with the previous patient from the outer plug wall 3, so that the unused part of the plug sleeve 6 covers the outer plug wall 3 for subsequent patients to use, thereby avoiding the risk of cross-infection. Furthermore, since there is no alcohol disinfection, damage to the hearing aid can be avoided, thereby improving the service life of the hearing aid.

[0038] As a preferred embodiment, based on the above method, the portion of the plug sleeve 6 that does not extend from the first opening 5 is rolled up, and when the plug sleeve 6 is in the unfolded state, the plug sleeve 6 has a cylindrical structure.

[0039] Furthermore, the portion of the plug sleeve 6 that does not extend from the first opening 5 is rolled up, which makes it easier for the receiving cavity 4 to receive the plug sleeve 6. When the plug sleeve 6 is pulled, the plug sleeve 6 is gradually unfolded, and the un-unfolded portion of the plug sleeve 6 is rolled up, which can reduce the risk of contamination of the unused portion of the plug sleeve 6. At the same time, when the plug sleeve 6 has a cylindrical structure, it is more conducive to the plug sleeve 6 to provide comprehensive protection to the outer plug wall 3.

[0040] As a preferred embodiment, based on the above method, the plug sleeve 6 is further elastic, and the portion of the plug sleeve 6 that fits onto the outer plug wall 3 is in a stretched state.

[0041] Furthermore, the sleeve 6 is made elastic, which on the one hand makes it easier to roll up the sleeve 6, and on the other hand improves the fit between the sleeve 6 and the outer wall 3, making it easier for the sleeve 6 to adhere to the outer wall 3.

[0042] As a preferred embodiment, based on the above method, the earplug 1 further includes a first plug body 7 and a second plug body 8, the first plug body 7 and the second plug body 8 are detachably connected, when the first plug body 7 and the second plug body 8 are connected, the first plug body 7 and the second plug body 8 cooperate to form a receiving cavity 4; when the first plug body 7 and the second plug body 8 are separated, the receiving cavity 4 is open.

[0043] Furthermore, by setting the first plug 7, the first plug 7 and the second plug 8 are detachably connected. When the first plug 7 and the second plug 8 are separated, the receiving cavity 4 is open, which facilitates the installation of the plug sleeve 6 into the receiving cavity 4 and improves the convenience of placing the plug sleeve 6 in the receiving cavity 4. At the same time, after the plug sleeve 6 is installed, the first plug 7 and the second plug 8 are connected, so that the receiving cavity 4 has a cavity structure with only one opening, which is the first opening 5, so that medical staff can pull the plug sleeve 6 later.

[0044] As a preferred embodiment, based on the above method, the first plug 7 and the second plug 8 are further connected by a threaded connection.

[0045] Furthermore, by threading the first plug 7 and the second plug 8 together, the ease of connecting or separating the first plug 7 and the second plug 8 is further improved.

[0046] Example 2: Based on the technical solution of Example 1, further details are provided below. Figures 1-5 As shown, the second plug 8 includes a plug part 9 and a plug part 10. The plug part 9 and the plug part 10 are slidably engaged, so that the plug part 9 can move relative to the plug part 10 along the central axis of the plug part 10. The plug part 10 is connected to the first plug 7.

[0047] An elastic element 11 is connected between the first plug part 9 and the second plug part 10. The elastic element 11 provides an initial tension to put the second plug 8 in an initial state. When the second plug 8 is in the initial state, the part of the plug sleeve 6 located at the first opening 5 is clamped by the first plug 7 and the first plug part 9.

[0048] When the first part of the plug body 9 moves away from the first plug body 7 relative to the second part of the plug body 10, the width of the first opening 5 gradually increases, which allows the first plug body 7 and the first part of the plug body 9 to release the clamping of the plug sleeve 6.

[0049] Furthermore, by providing a first plug part 9, a second plug part 10, and an elastic element 11, the elastic element 11 provides an initial tension to keep the second plug 8 in its initial state. At this time, the portion of the plug sleeve 6 located at the first opening 5 is clamped by the first plug 7 and the first plug part 9, which reduces the probability of pulling the plug sleeve 6 out of the receiving cavity 4 and improves the stability of the position of the plug sleeve 6 fitted on the outer plug wall 3. Specifically, one side of the first plug 7 forms one side wall of the first opening 5, and one side of the second plug 8 forms the other side wall of the first opening 5. Thus, when needed... When a new plug sleeve 6 is placed on the outer plug wall 3, the width of the first opening 5 is gradually increased by moving the plug body part 9 away from the first plug body 7 relative to the plug body part 10, thereby releasing the first plug body 7 and the plug body part 9 from clamping the plug sleeve 6. In this state, the plug sleeve 6 can be pulled so that a new plug sleeve 6 can be placed on the outer plug wall 3. After the new plug sleeve 6 is placed on the outer plug wall 3, when the external force is released, the elastic element 11 restores its deformation, so that the second plug body 8 returns to its initial state, and the first plug body 7 and the plug body part 9 clamp the plug sleeve 6 again.

[0050] As a preferred embodiment, based on the above method, the first plug body 7 is further provided with a first channel 12, and a push rod 13 is provided in the first channel 12. The push rod 13 is used to abut against the first part of the plug body 9 to push the first part of the plug body 9 to move relative to the second part of the plug body 10, so as to change the width of the first opening 5.

[0051] Furthermore, by setting a push rod 13, when the push rod 13 is pushed along the length direction of the first channel 12, the push rod 13 can push the first part of the plug body 9 to move relative to the second part of the plug body 10, thereby changing the width of the first opening 5, thereby improving the convenience of adjusting the clamped state or the unclamped state of the plug sleeve 6.

[0052] As a preferred embodiment, based on the above method, the first plug body 7 is further provided with a retaining ring 14. The retaining ring 14 is used to fix the plug sleeve 6 fitted on the first plug body 7. The retaining ring 14 is an open-loop structure that can be elastically bent so that the retaining ring 14 is detachable.

[0053] Furthermore, by setting the retaining ring 14, the retaining ring 14 is an open-loop structure that can be elastically bent, so that the retaining ring 14 can be installed on or removed from the first plug body 7. At the same time, when the retaining ring 14 is installed on the first plug body 7, the retaining ring 14 can fix the plug sleeve 6 fitted on the first plug body 7, thereby further reducing the probability of the plug sleeve 6 shifting and improving the stability of the plug sleeve 6 fitted on the first plug body 7.

[0054] As a preferred embodiment, based on the above method, the retaining ring 14 is further provided with a cutting blade 15, and the first plug body 7 is provided with a groove. The groove is adapted to the cutting blade 15. When the retaining ring 14 is installed on the first plug body 7, the cutting blade 15 extends into the groove. By rotating the retaining ring 14 relative to the first plug body 7 around the central axis of the first plug body 7, the cutting blade 15 cuts the plug sleeve 6.

[0055] Furthermore, by providing a cutting blade 15 on the retaining ring 14 and a groove on the first plug body 7, when the retaining ring 14 is installed on the first plug body 7, the cutting blade 15 extends into the groove. By rotating the retaining ring 14 relative to the first plug body 7 around the central axis of the first plug body 7, the cutting blade 15 can cut the plug sleeve 6, thereby facilitating the separation of the used part from the unused part on the plug sleeve 6, further reducing the risk of cross-infection.

[0056] As a preferred embodiment, based on the above method, it further includes a sound column 16, which is connected to the first plug 7 and the first plug 7 is sleeved on the outer wall of the sound column 16.

[0057] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above.
