Description

Technical Field

[0001] This utility model relates to the technical field of hearing testing equipment, specifically to a pluggable barcode scanner and an otoacoustic screening device using the barcode scanner. Background Technology

[0002] Otoacoustic screening devices, also known as hearing screening devices, are generally used for hearing tests in newborns or adults. Especially for newborns, since they cannot generate effective feedback, the detection of hearing impairment in newborns typically involves emitting specific frequencies to monitor sound waves emitted from the cochlea. However, existing otoacoustic screening devices are mostly standalone instruments, requiring external devices such as computers for data sharing. This leads to situations where, when testing a batch of individuals, the results may not immediately correspond to the newborns' information and conditions. Manual memorization or recording can be prone to errors, and the inability to print and record screening results promptly can result in discrepancies between the results and the individual test. This is particularly problematic when some test subjects require paper copies of their results, as manual selection and recording are prone to errors and misunderstandings. Utility Model Content

[0003] To address the problems existing in the prior art, one objective of this invention is to provide a pluggable barcode scanner that can be used independently for scanning and can also be connected to an otoacoustic screening instrument for synchronous recording. A second objective of this invention is to provide an otoacoustic screening device that utilizes this barcode scanner, enabling the otoacoustic screening instrument to have an external barcode scanning function, facilitating the simultaneous recording of otoacoustic screening results from multiple newborns, and allowing for unified printing of the records.

[0004] The pluggable barcode scanner of this utility model includes a housing in the shape of an inverted L. A barcode scanning component and an illumination component are located at the bottom of the housing. A main control circuit board is located inside the housing and is connected to both the barcode scanning component and the illumination component. The barcode scanning component is used to identify barcode labels, and the illumination component is used to enhance the brightness of the barcode labels to be identified. The other end of the housing also has a slot adapted to an otoacoustic screening instrument. The main control circuit board is electrically connected to the otoacoustic screening instrument through an interface within the slot. A display screen electrically connected to the main control circuit board is located on the upper surface of the housing. The main control circuit board is used to display the content identified by the barcode scanning component on the display screen or transmit it to the otoacoustic screening instrument.

[0005] In one embodiment, a first switch is provided on the front side of the housing. The first switch is electrically connected to the main control circuit board and is used to control the start and stop of the barcode scanning component and the lighting component.

[0006] In one embodiment, the length of the outer casing is adapted to the hand, and a grip portion adapted to the hand is provided on the rear side of the corner of the outer casing.

[0007] In one embodiment, a cord is provided on the side of the outer casing.

[0008] The otoacoustic screening device of this utility model uses the above-mentioned pluggable barcode scanner, including a base and an otoacoustic screening instrument. The base is equipped with a controller, and the base is provided with a placement slot and a printer. The interface in the placement slot and the printer are electrically connected to the controller. The placement slot is adapted to the otoacoustic screening instrument and is used for electrical connection with the otoacoustic screening instrument. The printer is used to print out the information collected by the otoacoustic screening instrument or form a barcode label.

[0009] In one embodiment, the otoacoustic screening device has a second switch on its side. When the scanning device is connected to the otoacoustic screening device, the start and stop of the scanning component and the lighting component are controlled by the second switch.

[0010] In one embodiment, a first magnetic element is provided on both sides of the slot opposite its interface, and a second magnetic element adapted to the first magnetic element is provided at the bottom of the ear screening device.

[0011] Compared with the prior art, the beneficial effects of this utility model's technical solution are:

[0012] The barcode scanning device of this utility model can be used for easy barcode scanning on its own. By holding the outer shell with one hand, the barcode scanning component at the bottom can be used to scan the barcode. An illumination component provides brightness. It can also be connected to an otoacoustic screening instrument for synchronous recording. By fitting with the otoacoustic screening instrument through a slot, the barcode scanning information can be synchronized to the otoacoustic screening instrument, and the corresponding otoacoustic screening results can be temporarily recorded, eliminating errors caused by manual recording.

[0013] This invention enables an otoacoustic screening device to have an external barcode scanning function, facilitating the simultaneous recording of otoacoustic screening results for multiple newborns. After connecting the barcode scanning device, the scanned content is synchronized to the otoacoustic screening device. Once the otoacoustic screening device completes the test, the internal storage module can temporarily record the results synchronously based on the barcode information and the test results. When the otoacoustic screening device is returned to the placement slot of the base, it connects to the controller inside the base, which in turn connects to the printer and prints out the corresponding test results for each newborn based on the records. This avoids the errors that may occur with manual recording and the inconvenience of having to connect to the base to print after each test. Attached Figure Description

[0019] 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.

[0020] 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.

[0021] like Figures 1-3As shown, the pluggable barcode scanner of this utility model includes a housing 1, which is inverted L-shaped. The bottom of the housing 1 is provided with a barcode scanning component 2 and an illumination component 3. The housing 1 contains a main control circuit board 4, which is connected to the barcode scanning component 2 and the illumination component 3 respectively. The barcode scanning component 2 is used to identify barcode labels, and the illumination component 3 is used to enhance the brightness of the barcode label to be identified. The other end of the housing 1 is also provided with a slot 5 adapted to an otoacoustic screening instrument 6. The main control circuit board 4 is electrically connected to the otoacoustic screening instrument 6 through an interface in the slot 5. The upper surface of the housing 1 is provided with a display screen 9 electrically connected to the main control circuit board 4. The main control circuit board 4 is used to display the content identified by the barcode scanning component 2 on the display screen 9 or transmit it to the otoacoustic screening instrument 6. This utility model's barcode scanning device can be used independently for easy scanning. Simply hold the outer casing 1 with one hand and use the scanning component 2 at the bottom to scan codes, such as the barcode labels on the different wristbands worn by each newborn. The scanned content is displayed on the screen 9, and the illumination component 3 provides brightness, allowing scanning to be completed even in dimly lit rooms without affecting the newborn. Furthermore, the scanning device can be connected to an otoacoustic screening device 6 for synchronized recording. Through the slot 5, it is adapted to the otoacoustic screening device 6, synchronizing the scanned information to the device. After scanning and registration, otoacoustic screening is performed, and the corresponding screening results are temporarily recorded in the storage module, eliminating errors caused by manual recording. The device can also be connected to a computer for subsequent information retrieval, avoiding any discrepancies.

[0022] In one embodiment, for ease of use, a first switch 11 is provided on the front side of the housing 1. The first switch 11 is electrically connected to the main control circuit board 4 and is used to control the start and stop of the barcode scanning component 2 and the lighting component 3. Both the barcode scanning component 2 and the lighting component 3 can be controlled by different first switches 11, which can be buttons or touch keys. The user can operate them with their thumb on the front side while holding the housing 1 with one hand. The length of the housing 1 is adapted to the hand, and a hand grip 12 adapted to the hand is provided on the rear side of the corner of the housing 1, forming a matching groove to prevent slippage. Furthermore, a lanyard 13 can be provided on the side of the housing 1. Before use, the lanyard 13 can be looped around the wrist to further prevent the barcode scanning device from slipping and colliding, or to temporarily hang on the hand when there is nowhere else to place it.

[0023] like Figure 3 and Figure 4As shown, the otoacoustic screening device of this utility model uses the above-mentioned pluggable barcode scanning device, including a base 7 and an otoacoustic screening instrument 6. The base 7 is equipped with a controller, and the base 7 is respectively provided with a placement slot 71 and a printer 72. The interface in the placement slot 71 and the printer 72 are electrically connected to the controller. The placement slot 71 is adapted to the otoacoustic screening instrument 6 and is used for electrical connection with the otoacoustic screening instrument 6. The printer 72 is used to print out the information collected by the otoacoustic screening instrument 6 or form a barcode label. This invention enables existing otoacoustic screening devices (OHS) 6 to have an external barcode scanning function, facilitating the simultaneous recording of OHS screening results for multiple newborns. Holding the OHS screening device 6 in one hand and the barcode scanner in the other, the scanner is inserted into the slot 5 of the OHS screening device at the rear end of the OHS screening device 6. After the interface is properly connected, the scanned information is synchronously recorded in the built-in storage module of the OHS screening device 6. After the OHS screening device 6 completes the test, the internal storage module temporarily records the scanned information and test results simultaneously. Once the OHS screening device 6 is returned to the placement slot 71 of the base 7, it connects to the controller within the base 7, which in turn connects to the printer 72. Based on the recorded information, the printer prints out the corresponding test results for each newborn, avoiding potential errors from manual recording and the inconvenience of having to connect the base for printing after each test. Additionally, the printer 72 can be configured to print barcode labels that can be affixed to a wristband for easy binding with the newborn.

[0024] In one embodiment, when the scanning device is used alone, the scanning component 2 is controlled by the first switch 11. When the otoacoustic screening instrument 6 is connected to the scanning component 2, the second switch 8 provided on the side of the otoacoustic screening instrument 6 can more conveniently cooperate with the otoacoustic screening test to uniformly control the start and stop of the scanning component 2 and the lighting component 3, and also avoids accidental touch of the first switch 11 located on the front side of the housing 1.

[0025] In addition, a first magnetic element 51 is provided on both sides of the slot 5 opposite to its interface, and a second magnetic element 52 adapted to the first magnetic element 51 is provided at the bottom of the ear-scanning device 6. When the ear-scanning device 6 is inserted into the slot 5, in order to avoid misalignment of the interface, the first magnetic element 51 and the second magnetic element 52 can better position the device and ensure a stable connection between the scanning device and the ear-scanning device 6.
