Description

Technical Field

[0001] The utility model relates to the technical field of nystagmus imaging instruments, in particular to a dual-working mode electronic otoscope suitable for a portable nystagmus imaging instrument. Background Art

[0002] Before performing a temperature test for nystagmus examination, the subject's external auditory canal and middle ear need to be examined. This can reduce false positive results of the temperature test and improve the accuracy of diagnosis. Patients with external otitis or tympanic membrane perforation are prohibited from taking the temperature test. This requires the use of an otoscope for examination. Both traditional electronic otoscopes and video otoscopes can meet the examination requirements. Before the examination, a traditional electronic otoscope can be used to quickly check whether the subject's external auditory canal and tympanic membrane are intact. For those with intact external auditory canal and tympanic membrane, a temperature test can be performed directly. However, for those with external otitis or tympanic membrane perforation, it is necessary to record the results with video or images, and save the recorded video or images together with the nystagmus examination results under the subject's ID to facilitate subsequent follow-up visits and comparative studies of the doctor's nystagmus examination results. Traditional electronic otoscopes are convenient and fast to operate, can be viewed at any time, quickly screen, and save examination time, but cannot image the examination results. The video electronic otoscope can record the examination results as images or videos, but it is more complicated to operate than the traditional electronic otoscope, and the video electronic otoscope is a separate set of equipment, which cannot automatically save the examination video or image and the nystagmus view examination results under the same patient ID. When the patient returns for a follow-up visit or the doctor compares the patient's nystagmus view examination results, it is necessary to retrieve the image or video of the patient's external auditory canal and tympanic membrane examination from another video electronic otoscope device. This operation is prone to errors and will greatly increase the workload. This requires a dual-working mode electronic otoscope that takes into account the functions of traditional electronic otoscopes and video electronic otoscopes. The video electronic otoscope of the dual-working mode electronic otoscope can automatically transmit the collected video or image of the subject's external auditory canal and tympanic membrane to the portable nystagmus viewer and save the record to the patient ID. Utility Model Content

[0003] In order to solve the above technical problems, the present invention provides a dual-working mode electronic otoscope suitable for a portable nystagmography device.

[0016] The beneficial effects of the utility model are:

[0017] 1. This utility model solves the problem that the advantages of traditional electronic otoscopes and video electronic otoscopes cannot be used compatibly in nystagmus examinations. A dual-working mode electronic otoscope with compatible hardware and software is designed on a portable nystagmus imaging device, which can quickly switch between traditional electronic otoscopes and video electronic otoscopes.

[0018] 2. The camera part of the video electronic otoscope is pushed out and retracted using the principle of linkage of the rack, hand-turned roller and track groove. The user only needs to turn the roller on the outside of the shell to achieve this operation, which is convenient and quick.

[0019] 3. The mirror cavity and the in-ear cone head are connected by gold finger pins and contact holes for circuit and signal conduction, eliminating the need for wiring in a small space, making the entire structure simple and practical.

[0020] 4. The traditional electronic otoscope is designed with a lighting lamp, a light-transmitting cover, and a magnifying glass on the top, which can greatly improve the clarity of observation while preventing dust from entering;

[0021] 5. The lighting of the traditional electronic otoscope is installed on an integrated LED light ring, which is convenient for replacement and adjustment of the illumination angle. The lighting is also designed with a control switch, which can be turned off when not in use or after use, saving power to the host.

[0022] 6. The video electronic otoscope part can transmit the collected video of the external auditory canal and tympanic membrane to the instrument host in real time, and display the video images of the tympanic membrane and external auditory canal in real time on the external display screen. The camera can be controlled on the external display screen to take pictures or record videos of the external auditory canal or tympanic membrane. The system will automatically save the pictures or videos to the ID of the current test patient, and the same storage path as the nystagmus view examination results will be used, which can facilitate subsequent follow-up visits and comparative studies of the nystagmus view examination results.

[0023] 7. The utility model realizes the switching between traditional electronic otoscope and video electronic otoscope by pushing out and retracting the track camera. When the track camera is retracted, the in-ear cone head and the entire main mirror cavity will form a viewing channel. The in-ear cone head is partially placed into the patient's ear canal, and the light control switch is pressed to turn on the LED light. Under the illumination of the LED light inside the main mirror cavity and the light transmission effect of the external light-transmitting cover, the patient's ear canal and eardrum can be clearly observed through the magnifying glass on the top of the main mirror cavity; when the track camera is pushed out and the screen of the portable nystagmography instrument is switched to the video electronic otoscope interface, the track camera will start working, and the end of the camera will turn on the LED light. The light beads will turn on automatically, and the video images of the patient's ear canal and membrane will be displayed in real time on the instrument screen. The patient's ear canal and eardrum can be recorded or photographed through the photo and video icon buttons on the screen, and the system will automatically save the photos or videos to the patient ID; when the track camera is pushed out, the visual channel connecting the in-ear cone head and the entire mirror cavity will be blocked by the track camera, and the traditional electronic otoscope will not be available at this time; the present invention can realize the rapid switching between the traditional electronic otoscope and the video electronic otoscope, and the electronic otoscopes in the two working modes are fully matched and compatible with the hardware and software of the portable nystagmus viewer, and are highly practical and convenient.

[0027] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0028] like Figure 1 and Figure 2 As shown, a dual-mode electronic otoscope suitable for a portable nystagmography device includes: a main mirror cavity housing 204; a first light-transmitting cover 202 and a second light-transmitting cover 203, respectively disposed on mounting holes on both sides of the main mirror cavity housing 204; a magnifying glass 201, disposed on the mounting hole at the front end of the main mirror cavity housing 204; an LED light ring 205, disposed on the mounting hole at the rear end of the main mirror cavity housing 204, and having a plurality of LED lighting lamps 206 evenly distributed thereon; an in-ear cone head housing 211, mounted on the rear end of the main mirror cavity housing 204; a light control switch 209, disposed on the side wall of the in-ear cone head housing 211 and connected in series to the L On the power supply circuit of the ED lighting lamp 206; the light-shielding plug 210 is arranged on the air-avoidance hole on the side wall of the in-ear cone head shell 211; the track camera 208 is arranged in the in-ear cone head shell 211; the hand-activated roller a207 is arranged on the mounting hole on the side wall of the in-ear cone head shell 211, and is engaged with the rack vertically arranged on the track camera 208, so that when the hand-activated roller a207 is rotated, the track camera 208 can be driven to move up and down; a flexible cable 212, one end of which is respectively connected to the signal output end and the power supply circuit of the track camera 208, and the other end is connected to the external display interaction device and the battery 115.

[0029] Specifically:

[0030] ① The top of the main mirror cavity housing 204 is a magnifying glass 201. The two light-transmitting windows of the main mirror cavity housing 204 are respectively a first light-transmitting cover 202 and a second light-transmitting cover 203. The inner side of the lower end of the main mirror cavity housing 204 is an LED light ring 205 with three white light LEDs. The back of the main mirror cavity housing 204 is a flexible cable 212.

[0031] ② On one side of the in-ear cone head shell 211 is the light control switch 209, and on the other side is the hand dial wheel a207, which is connected to the hand dial wheel a207 and the track camera 208, and at the top of the track camera 208 is a cable;

[0032] ③ Connect and assemble the main mirror cavity shell 204 assembled in step 1 and the in-ear cone head shell 211 assembled in step 2 to form this dual-working mode electronic otoscope; in this device, pressing the lamp hole switch 209 can control the on and off of the three white light LED lights, and the control process is: when the lights are off, press the switch to light them up, and press the switch again to turn them off; in this device, toggling the hand dial wheel a207 can control the forward and backward movement of the video electronic otoscope track camera 208, and the control process is: when the track camera 208 moves back to the end point, toggle the hand dial wheel a207 clockwise to move the camera forward, and when the camera moves forward to the end point, toggle the hand dial wheel a207 counterclockwise to move the camera backward;

[0033] The principle of the in-ear cone head and the main mirror cavity circuit and signal conduction is as follows:

[0034] There are four gold finger pins on the cross section of the lower end of the main mirror cavity housing 204, and there are four contact holes at corresponding positions on the cross section of the top end of the in-ear cone head housing 211. After the main mirror cavity housing 204 and the in-ear cone head housing 211 are assembled according to the positioning, the four gold finger pins on the main mirror cavity housing 204 will be inserted into the four contact holes on the in-ear cone head housing 211. Because the four gold finger pins on the main mirror cavity housing 204 are connected to the flexible cable 212, the circuit and signal between the in-ear cone head housing 211 and the main mirror cavity housing 204 are conductive.

[0035] The principle of orbital camera movement is:

[0036] ① There is a track camera support frame on the inner side of the in-ear cone head shell 211, and there is an air avoidance hole below the track camera support frame and in parallel with the support frame; ② The front of the top of the track camera 208 is a track groove, and the side of the track groove is a rack. There is a sliding track on the cross section below the main mirror cavity. The track groove of the track camera 208 is installed on the sliding track in the correct direction, and then the hand-activated roller a207 is installed on the corresponding rotating shaft on the in-ear cone head shell 211; ③ The teeth of the hand-activated roller a207 will engage with the rack on the track camera 208, and the back of the top of the track camera 208 will be against the track camera support frame, because the track groove on the front of the top of the track camera is connected to the sliding track, at this time, toggling the hand-activated roller a207 can drive the rack on the track camera 208 to move, thereby controlling the retraction and extension of the track camera 208, specifically, toggling the hand-activated roller a207 clockwise to extend the track camera, and toggling the hand-activated roller a207 counterclockwise to retract the track camera;

[0037] ④ Because the track groove and rack travel on the track otoscope and the overall offset angle of the camera have been designed in structure, when the hand-driven roller a207 is turned clockwise to the bottom, the track camera 208 will be pushed out to the center of the inner cavity of the in-ear cone head. When the hand-driven roller a207 is turned counterclockwise to the bottom, the track camera 208 will be retracted into the air avoidance hole. In addition, a light-shielding plug 210 is designed on the outside of the air avoidance hole to prevent light from entering when the track camera 208 is pushed out.

[0038] The process of switching between traditional electronic otoscope and video electronic otoscope is as follows:

[0039] When the track camera 208 is retracted, the in-ear cone head shell 211 and the entire mirror cavity will form a complete viewing channel. At this time, press the light control switch 209 to turn on the LED light, and then put the in-ear cone head shell 211 into the patient's ear canal. Under the illumination of the LED light ring 205 and the light transmission effect of the first light-transmitting cover 202 and the second light-transmitting cover 203, the patient's ear canal and eardrum can be clearly observed through the magnifying glass 201. This is the traditional electronic otoscope working mode; push out the track camera 208, switch the instrument screen to the video electronic otoscope interface, and the track camera 208 will start, and the patient's ear canal will be displayed in real time on the instrument screen. The video image of the patient's ear canal and eardrum can be viewed by clicking the photo and video icon buttons on the screen, and the system will automatically save the photo or video to the patient's ID. This is the working mode of the video electronic otoscope. When the track camera 208 is pushed out, the in-ear cone head shell 211 and the entire mirror cavity viewing channel will be blocked by the track camera 208. At this time, the traditional electronic otoscope will be unusable, and the LED light ring 205 on the traditional electronic otoscope can be turned off, because there is a circle of LED light beads at the end of the track camera 208 of the video electronic otoscope, which will automatically turn on when the track camera is started.

[0040] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention. In addition, the appended claims of the present invention are intended to cover all variations and modifications that fall within the scope and metes and bounds of the appended claims, or equivalents thereof.
