Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of otoacoustic screening instruments, specifically to a network-connected card-type otoacoustic screening instrument. Background Technology
[0002] Otoacoustic screening devices (OACs) are primarily used for hearing screening in newborns. They employ unique noise shielding and attenuation technology, allowing them to complete tests smoothly even in normal ambient noise conditions and improving test accuracy by assessing environmental noise levels. Most existing OAC devices use a USB interface to connect to a computer for data sharing, supporting the digital information required for remote consultations. However, in certain emergency or special situations, wireless network connectivity is also necessary for the OAC device. In such cases, finding a computer connection for remote data sharing may not be readily available, necessitating that the OAC device itself possesses wireless network communication capabilities. However, directly installing wireless communication devices within such small and readily available instruments is risky, as they could easily be lost or misused by malicious individuals who could obtain internal information, especially sensitive patient information such as that of newborns, causing unnecessary losses. Therefore, wireless communication for such devices requires a network card insertion method, where the wireless network card is inserted only when in use to connect to the network. Furthermore, protective measures must be designed to prevent the misuse of external wireless network cards. Utility Model Content
[0003] To address the problems existing in the prior art, the present invention aims to provide a network-connected card-type otoacoustic screening device. This invention integrates a wireless network card into the original otoacoustic screening device to facilitate data networking and recording. It also features dual protection for the card insertion structure and data security, preventing the inserted wireless network card from easily falling out during use. Furthermore, it ensures that only a compatible card insertion structure can be used for wireless network transmission, effectively improving the security of user information.
[0004] The present invention discloses a network-connected card-type ear screening device, comprising a main body and a card insertion structure. The main body has a slot, and threaded holes are respectively provided on both sides of the slot. A first switch is provided in one of the threaded holes. The main body also contains a storage chip, a wireless communication chip, and an RF antenna that are electrically connected in sequence. The slot is connected to the wireless communication chip through the first switch. The card insertion structure has a wireless network card adapted to the slot. Screws are rotatably connected to both sides of the card insertion structure corresponding to the slot, and when one of the screws engages with the threaded hole, the first switch is activated.
[0005] In one embodiment, the slot is located in a groove at the bottom of the body, and the distances between the slot and the front and rear sides of the body in the thickness direction are different, and the thickness of the card insertion structure is adapted to the body.
[0006] In one embodiment, the main body has card slots on the front and rear sides near the bottom, and the card insertion structure extends toward the wireless network card and has a card hook that matches the card slot.
[0007] In one embodiment, a handle extends outward from the left or right side of the bottom of the main body, and a second switch is provided at the corner of the handle and the main body. The second switch is a control switch for the main circuit, and a power cord hole is provided at the end of the handle away from the main body.
[0008] In one embodiment, the handle has a groove adapted to fit a human hand, and the groove has a pattern.
[0009] In one embodiment, the top of the main body is provided with an interface for connecting the probe and the light, and the front side of the main body is also provided with an indicator light corresponding to the interface.
[0010] Compared with the prior art, the beneficial effects of this utility model's technical solution are:
[0011] This invention incorporates a wireless network card into the original otoacoustic screening device to facilitate data networking and transmission. It also features dual protection for the card insertion structure and data security. The card insertion structure utilizes screws on both sides screwed into threaded holes, allowing the wireless network card to be inserted into the slot and secured. This prevents the wireless network card from easily falling out during user movement. Furthermore, because the screws need to press against the first switch in the threaded hole for the wireless network card to connect to the wireless communication chip, enabling the otoacoustic screening device's storage chip to wirelessly transmit data, ordinary wireless network cards cannot steal user information by inserting into this otoacoustic screening device without a compatible insertion structure, thus providing a certain level of protection for user information security.

Detailed Implementation
[0015] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.
[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can be described as the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0017] like Figure 1 and Figure 2 As shown, this utility model discloses a network-connected card-type ear screening device, including a main body 1 and a card insertion structure 2. The main body 1 is provided with a slot 11, and threaded holes 12 are provided on both sides of the slot 11. A first switch 13 is provided in one of the threaded holes 12. The main body 1 is also provided with a storage chip, a wireless communication chip and an RF antenna connected in sequence. The slot 11 is connected to the wireless communication chip through the first switch 13. The card insertion structure 2 is provided with a wireless network card 21 that is compatible with the slot 11. Screws 22 are rotatably connected to both sides of the card insertion structure 2 corresponding to the slot 11, and when one of the screws 22 is engaged with the threaded hole 12, the first switch 13 is connected. This invention incorporates a wireless network card 21 into the original ear-acoustic screening device to facilitate data networking and transmission. It also features dual protection for the card insertion structure 2 and the data security. The card insertion structure 2 uses screws 22 on both sides to screw into threaded holes 12, and the wireless network card 21 is inserted into the slot 11 to secure it. This prevents the wireless network card 21 from easily falling out during user movement. Furthermore, because the screws 22 need to press against the first switch 13 in the threaded hole 12 for the wireless network card 21 to connect to the wireless communication chip and enable wireless data transmission from the ear-acoustic screening device's storage chip, a common wireless network card 21 cannot steal user information by inserting into the ear-acoustic screening device without a compatible card insertion structure 2, thus providing a certain level of protection for user information security.
[0018] In one embodiment, the wireless network card 21 and the slot 11 generally cooperate in a form similar to a USB connector. The slot 11 is located in a groove 14 at the bottom of the body 1, and the distance between the slot 11 and the front and rear sides of the body 1 in the thickness direction are different. The thickness of the card insertion structure 2 is adapted to the body 1. The groove 14 formed at the bottom of the body 1 is adapted to the card insertion structure 2, which facilitates the positioning and insertion of the card insertion structure 2. Moreover, since the distance between the slot 11 and the upper and lower edges of the body 1 is different, the card insertion structure 2 is prevented from colliding with the interface in opposite directions during the cooperation, reducing wear between the interfaces. The fixing is completed by the cooperation of the screw 22 and the threaded hole 12. In addition, the front and rear sides of the body 1 near the bottom are provided with card slots 15, and the card insertion structure 2 extends towards the wireless network card 21 and is provided with a hook 23 adapted to the card slot 15. The setting of the card slot 15 and the hook 23 allows the card insertion structure 2 to be pre-positioned when inserted. Before the screw 22 is screwed into the threaded hole 12, the card insertion structure 2 can be relatively fixed on the body 1 to achieve positioning.
[0019] In one embodiment, a handle 16 extends outward from the left or right side of the bottom of the main body 1. A second switch 17 is located at the corner where the handle 16 meets the main body 1. The second switch 17 is the control switch for the main circuit. A power cord hole 18 is located at the end of the handle 16 furthest from the main body 1. The main body 1 of the otoacoustic screening device is L-shaped due to the handle 16, allowing the user to hold the handle 16 with one hand while operating the otoacoustic screening device with the other hand, without obstructing the screen and making it easy to hold the main body 1 securely. The position of the second switch 17 facilitates the control of starting the otoacoustic screening device. The otoacoustic screening device can be used directly by connecting to a fixed power source through the power cord hole 18 or after charging. Furthermore, the handle 16 has a groove adapted to fit the human hand, and the groove has a pattern to increase friction, making it easier to use the otoacoustic screening device with one hand. In addition, the top of the main body 1 has an interface for connecting the probe and the light, and the front of the main body 1 also has an indicator light 19 corresponding to the interface to indicate the connection and usage status of the probe and the light.
