Abstract
Description
Technical Field
[0001] This application relates to the field of CT scanning, and more particularly to a prompting device for use in CT scanners. Background Technology
[0002] During CT scans, some patient positions require breath-holding to obtain ideal diagnostic images. Normal individuals can follow the voice prompts played during the CT scan to perform the corresponding actions. However, some deaf or hearing-impaired patients cannot cooperate with the CT scan according to the corresponding voice prompts. Therefore, it is necessary to use light or pictures to remind hearing-impaired patients to perform the corresponding breathing actions to complete the CT scan. Utility Model Content
[0003] To address the aforementioned issues, this application provides a prompting device for use in CT scanners.
[0004] The technical solution of the prompting device for CT scanner provided in this application is as follows:
[0005] A prompting device for use in a CT scanner includes a base and a frame disposed on top of the base. An airbag is disposed within the frame, and a limiting component for limiting the airbag is disposed within the frame. The sidewall of the airbag and the inner wall of the frame enclose a grasping space for a deaf-mute patient to extend their hand.
[0006] Furthermore, the limiting component includes a limiting rod and a clamping cylinder. The limiting rod is vertically arranged and one end is connected to the inner top wall of the frame, and the other end is connected to the top wall of the base. The airbag is disposed inside the clamping cylinder. Both the airbag and the clamping cylinder are sleeved on the limiting rod. The clamping cylinder has a through groove on its side wall facing the frame leg for the airbag to extend out.
[0007] Furthermore, the base is equipped with an air pump for inflating and deflating the airbag.
[0008] Furthermore, the base is provided with a limiting block for limiting the rotation angle of the clamping cylinder.
[0009] Furthermore, a vibration motor is installed inside the base.
[0010] Furthermore, a nano-adhesive layer is provided at the bottom of the base.
[0011] Furthermore, the base is equipped with a controller electrically connected to the air pump and the vibration motor. When the doctor inputs an "inhale" signal to the controller, the controller controls the air pump to inhale and the airbag to inflate. When the doctor inputs an "exhale" signal to the controller, the controller controls the air pump to deflate and the airbag to shrink. When the doctor inputs a "hold your breath" signal to the controller, the vibration motor starts.
[0012] In summary, this application includes at least one of the following beneficial technical effects:
[0013] By combining the base, frame, and airbag, a grasping space is formed within the frame for hearing-impaired individuals to reach into. The physical changes (expansion / contraction) of the airbag provide tactile feedback, solving the problem of receiving commands due to hearing impairment during CT examinations. This allows patients to intuitively perceive operational commands (such as inhalation, exhalation, and breath-holding) through tactile sensation, thus improving their cooperation during examinations.
[0014] The combination design of the limiting rod and the clamping cylinder restricts the position of the airbag, so that the airbag can only expand or contract in the direction of the grasping space through the through groove of the clamping cylinder, avoiding the confusion of tactile signals caused by disordered expansion of the airbag, which helps to improve the accuracy of tactile feedback in the patient's hand contact area.
[0015] The limiting block restricts the rotation angle of the clamping cylinder, making it easy to adapt to different hand sizes. This ensures that the air bladder's groove is always aligned with the grasping space, minimizing the risk of the air bladder deviating from the patient's hand contact area due to the rotation of the clamping cylinder, and guaranteeing the stability and reliability of the tactile signal transmission direction.
[0016] The vibration motor can provide additional tactile stimulation through vibration during the "hold your breath" command, which complements the static inflation state of the airbag and enhances the patient's perception of the "hold your breath" command, which needs to be maintained continuously.
[0017] The nano-adhesive layer at the bottom of the base allows for non-destructive bonding between the device and the CT scanner surface, ensuring the device remains stable and does not shift during the examination. It also supports quick disassembly and reuse, adapting to the installation requirements of different CT scanner models and improving the device's versatility.
[0018] By combining the mechanical deformation of the airbag (tactile sensation) with the vibration of the vibrating motor (tactile sensation + somatosensory sensation), multi-dimensional and multi-level instruction prompts are provided for hearing-impaired individuals, making up for the limitations of a single signal. This helps patients clearly and accurately receive and execute operational instructions in complex examination environments. Attached Figure Description

[0021] The following will further elaborate on this application in conjunction with the attached Figure 1 drawings.
[0022] The embodiment of this application discloses a prompting device applied to a CT machine.
[0023] Referring to Figure 1 , a prompting device applied to a CT machine includes a base 1 and a frame 2. In this embodiment, the frame 2 is set in a "冂" shape. The two legs of the frame 2 are fixedly connected to the top of the base 1. An airbag 3 is arranged inside the frame 2, and a limiting component 4 for limiting the airbag 3 is arranged inside the frame 2. A grasping space 5 for the hand of the hearing-impaired person to reach is formed by enclosing between the side wall of the airbag 3 and the inner wall of the frame 2.
[0024] The limiting component 4 includes a limiting rod 41 and a clamping cylinder 42. In this embodiment, the limiting rod 41 is set as a round rod. The limiting rod 41 is arranged vertically, with one end connected to the inner top wall of the frame 2 and the other end connected to the top wall of the base 1. The airbag 3 is arranged inside the clamping cylinder 42. Both the airbag 3 and the clamping cylinder 42 are sleeved on the limiting rod 41. A through groove 6 for the airbag 3 to extend out is opened on the side wall of the clamping cylinder 42 facing the leg of the frame 2. An air pump for inflating and deflating the airbag 3 is arranged inside the base 1, and a vibration motor is arranged inside the base 1.
[0025] Through the cooperation of the base 1, the frame 2 and the airbag 3, a grasping space 5 for the hand of the hearing-impaired person to reach is formed inside the frame 2. The physical shape change (expansion / contraction) of the airbag 3 is used to provide tactile feedback, solving the problem of difficult command reception caused by hearing impairment during CT examination for the hearing-impaired person, enabling the patient to directly perceive operation commands (such as inhaling, exhaling, holding breath, etc.) through the tactile sensation of the hand, and improving the cooperation degree during the examination; the combined design of the limiting rod 41 and the clamping cylinder 42 limits the position of the airbag 3, enabling the airbag 3 to only expand or contract towards the grasping space 5 through the through groove 6 of the clamping cylinder 42, avoiding the confusion of tactile signals caused by the disorderly expansion of the airbag 3, and being beneficial to improving the accuracy of the tactile feedback in the area where the patient's hand contacts.
[0026] Limiting blocks 7 for limiting the rotation angle of the clamping cylinder 42 are arranged on the base 1. In this embodiment, there are two limiting blocks 7, and the two limiting blocks 7 are symmetrically arranged along the axis center of the limiting rod 41.
[0027] The limiting block 7 restricts the rotation angle of the clamping cylinder 42, making it easy to adapt to different hand sizes. This ensures that the through groove 6 of the airbag 3 is always aligned with the grasping space 5, minimizing the risk of the airbag 3 deviating from the patient's hand contact area due to the rotation of the clamping cylinder 42, and guaranteeing the stability and reliability of the tactile signal transmission direction.
[0028] A nano-adhesive layer 8 is provided at the bottom of the base 1.
[0029] The nano-adhesive layer 8 at the bottom of the base 1 enables non-destructive bonding between the device and the CT machine surface, ensuring the device remains stable and does not shift during the examination, while also supporting quick disassembly and reuse. This adapts to the installation requirements of different CT machine models and improves the device's versatility.
[0030] The base 1 is equipped with a controller 9 that is electrically connected to the air pump and the vibration motor. When the doctor inputs the "inhale" signal to the controller 9, the controller 9 controls the air pump to inhale and the air bag 3 to inflate. When the doctor inputs the "exhale" signal to the controller 9, the controller 9 controls the air pump to deflate and the air bag 3 to shrink. When the doctor inputs the "hold your breath" signal to the controller 9, the vibration motor starts.
[0031] Combining the mechanical deformation (tactile sensation) of the airbag 3 with the vibration of the vibration motor (tactile sensation + somatosensory sensation), it provides multi-dimensional and multi-level instruction prompts for hearing-impaired individuals, making up for the limitations of a single signal. This helps patients clearly and accurately receive and execute operational instructions in complex examination environments. The vibration motor can provide additional tactile stimulation through vibration during the "hold your breath" instruction, complementing the static inflation state of the airbag 3 and enhancing the patient's perception of the "hold your breath" instruction, which needs to be maintained continuously.
[0032] The implementation principle of a prompting device applied to a CT scanner according to an embodiment of this application is as follows: through the cooperation of the base 1, frame 2 and airbag 3, a grasping space 5 is formed in the frame 2 for the hands of hearing-impaired patients to reach in. The physical shape change (expansion / contraction) of the airbag 3 provides tactile feedback, which solves the problem of hearing-impaired patients receiving instructions during CT examinations due to hearing impairment. It allows patients to intuitively perceive operation instructions (such as inhalation, exhalation, breath-holding, etc.) through tactile sensation, thereby improving the cooperation rate during the examination.
[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
