Description

Technical Field

[0001] The present invention relates to the field of medical diagnosis and surgical instruments, and specifically to a vision detection remote control with a locatable light source. Background Art

[0002] In the ophthalmic diagnosis and treatment scenario, traditional vision measurement relies on the interaction between an electronic display screen and a remote control due to environmental noise interference. However, in a low-light environment and the lack of stereoscopic vision caused by monocular occlusion, it is difficult for patients to accurately locate the remote control buttons. Especially among myopic people, the unoccluded eye is more sensitive to light changes due to the accommodation lag phenomenon after monocular occlusion. In a low-light environment, the tactile feedback is chaotic and prone to accidental touch, and the existing single physical marking or sound prompt scheme has insufficient recognition in complex operation scenarios, resulting in the patient being forced to interrupt the measurement process due to repeated button searching or misoperation, significantly prolonging the single detection time, and this problem directly exacerbates the phenomenon of repeated detection. Summary of the Invention

[0003] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a vision detection remote control with a locatable light source to solve the problems proposed in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A vision detection remote control with a locatable light source, comprising a housing, a circuit board installed inside the housing, a light guide column installed on the circuit board, and a trigger assembly installed on the circuit board;

[0005] The trigger assembly includes a plurality of first buttons and a light guide bar, and the light guide bar is located at the gap position between adjacent first buttons;

[0006] The housing is provided with an opening, and the first buttons extend out of the opening for the user to press;

[0007] A light source is placed inside the light guide column, and the light source is directionally emitted along the direction of the light guide column to the light guide bar.

[0008] As a further improvement of the present invention, the trigger assembly includes a connecting piece and a second button. The connecting piece is provided with a through hole. The first buttons are arranged circumferentially along the through hole. The second button is located in the through hole and is exposed after passing through the housing. One end of the light guide column is connected to the circuit board, and the other end is connected to the second button. The periphery of the second button is transparent, and the light guide bar is connected to the transparent part of the second button for guiding the light source transmitted by the light guide column to the second button.

[0009] As a further improvement of the present invention, the light guide column is provided with a guiding groove, and the second button is provided with a guiding key corresponding to the guiding groove. The second button forms a keyway fit with the guiding groove through the guiding key for restricting the rotation of the light guide column.

[0010] As a further improvement of the present invention, connecting arms for supporting the connecting member are provided on both sides of the second button, and the connecting arms on both sides are arranged in a staggered manner and are connected to the circuit board.

[0011] As a further improvement of the present invention, the connecting member is provided with a fixing groove for accommodating the connecting arm, and part of the connecting arm is located in the fixing groove.

[0012] As a further improvement of the present invention, the triggering assembly is in an inclined state relative to the bottom of the housing to adapt to the holding posture of the user's hand.

Detailed description of the invention

[0023] The present invention will be further described in detail below with reference to the embodiments given in the accompanying drawings.

[0024] Referring to Figures 1-5 As shown, a vision detection remote control with a locatable light source includes a housing 1, a circuit board 2 installed inside the housing 1, a light guide column 3 installed on the circuit board 2, and a trigger assembly 4 installed on the circuit board 2; the trigger assembly 4 includes a plurality of first buttons 41 and a light guide bar 42, and the light guide bar 42 is located at the gap position between adjacent first buttons 41; the housing 1 is provided with an opening, and the first buttons 41 extend out of the opening for the user to press; a light source is placed inside the light guide column 3, and the light source is directionally emitted along the direction of the light guide column 3 to the light guide bar 42.

[0025] The light source is placed inside the light guide column 3. A reflective mirror surface can be provided inside the light guide column 3 to enhance the light intensity of the light guide column 3 conducted to the light guide bar 42. The light is emitted and conducted along the direction of the light guide column 3 to the light guide bar 42. The light guide bar 42 is embedded in the gap between adjacent first buttons 41 to guide the light inside the light guide column 3, so that the light evenly covers the gap, forming a light band mark, optimizing the light source distribution. In a low-light environment, the user can quickly locate the position of the first button 41 through the visual feedback of the light guide bar 42, avoiding tactile confusion caused by monocular occlusion or adjustment lag. The directional design of the light guide column 3 and the light guide bar 42 ensures that the light of the light source only propagates along the set path, reducing the interference of stray light, improving the recognition rate of the first button 41 area, enhancing the accuracy of user operation, thereby reducing the mis-touch rate and shortening the detection time.

[0026] In the optimization, the trigger assembly 4 includes a connecting member 43 and a second button 44. The connecting member 43 is provided with a through hole 431. The first buttons 41 are arranged circumferentially along the through hole 431. The second button 44 is located in the through hole 431 and is exposed after passing through the housing 1. One end of the light guide column 3 is connected to the circuit board 2, and the other end is connected to the second button 44. The second button 44 is transparent around its body, and the light guide bar 42 is connected to the transparent part of the second button 44 for guiding the light source transmitted from the light guide column 3 to the second button 44.

[0027] The second button 44 can be made of acrylic material and is transparent around its body. An opaque material can be added to the top of the second button 44 to block the light, thereby controlling the light propagation direction, improving the uniformity and intensity of the light around the body. The light source is transmitted from the light guide column 3 to the second button 44, and the light guide bar 42 is connected to the transparent part of the second button 44, so as to guide the light into the light guide bar 42, forming a high-brightness mark in the gaps adjacent to the plurality of first buttons 41 and around the body of the second button 44. The light passes through the light guide bar 42 and emerges, enhancing the visual feedback. The through hole 431 design of the connecting member 43 makes the first button 41 and the second button 44 form a hierarchical layout. A height difference can be set between the first button 41 and the second button 44 during installation to increase the distinctiveness, thereby avoiding mis-touch by the user.

[0028] In the optimization, the light guide column 3 is provided with a guide groove 31 , and the second button 44 is provided with a guide key 441 corresponding to the guide groove 31 . The second button 44 forms a keyway fit with the guide groove 31 through the guide key 441 to limit the rotation of the light guide column 3 .

[0029] The cooperation between the guide key 441 and the guide groove 31 constrains the rotation of the light guide column 3 through mechanical limiting. When the second button 44 is assembled with the light guide column 3, the guide key 441 is embedded in the guide groove 31, so that the light guide column 3 can only move along the axial direction but cannot rotate around its own axis, ensuring that the light source is always accurately transmitted to the transparent part of the second button 44 along the preset direction of the light guide column 3. At the same time, limiting the rotation can reduce the friction between the light guide column 3 and the second button 44. If a material such as a reflective surface is provided between the light guide column 3 or the second button 44, limiting the rotation can effectively avoid changes in the internal light path and avoid misalignment or scattering of the light path caused by rotation. In addition, the guide groove 31 and the guide key 441 simplify the alignment and installation process of the light guide column 3 and the second button 44, reduce assembly errors, and avoid structural loosening caused by external force or vibration during long-term use.

[0030] In the optimization, connecting arms 45 for supporting the connecting member 43 are arranged on both sides of the second button 44 , and the connecting arms 45 on both sides are staggered and connected to the circuit board 2 .

[0031] The staggered connecting arms 45 disperse the force points of the connecting piece 43, the first button 41 and the second button 44, disperse the local force applied to the circuit board 2 when pressed, and avoid tilting or loosening of the connecting piece 43 when pressing the first button 41 and the second button 44. The connecting arm 45 and the circuit board 2 can be fixed with screws or bolts to enhance structural stability.

[0032] In the optimization, the connecting member 43 is provided with a fixing groove 432 for accommodating the connecting arm 45 , and part of the connecting arm 45 is located in the fixing groove 432 .

[0033] The fixing groove 432 limits the connection arm 45, increases the connection between the connection arm 45 and the connection member 43, and prevents the connection arm 45 from being displaced due to vibration or frequent pressing.

[0034] In the optimization, the trigger assembly 4 is tilted relative to the bottom of the housing 1 to adapt to the user's hand holding posture.

[0035] The tilt angle is designed according to the joint curvature of the human hand when it is naturally held, which reduces wrist fatigue, allows users to hold their hands naturally when using it, and increases user comfort. The tilted layout of the trigger component 4 can also optimize the light projection direction, so that the light band of the light guide strip 42 is closer to the user's field of vision, further improving positioning efficiency.

[0036] During optimization, a vision detection display screen 5 is used in cooperation with a vision detection remote control with a locatable light source.

[0037] When starting the test, click the start test button on the remote control. After the vision detection display screen 5 receives the instruction from the remote control, it will display the vision detection chart in real time. The user presses the corresponding orientation on the remote control according to the actual orientation of the detection chart seen, and feeds back the actual detection chart seen through the remote control, thereby reducing errors caused by personnel communication and improving the detection efficiency. At the same time, the remote control and the vision detection display screen 5 can be extended with a wireless communication module (such as Bluetooth or infrared) to support remote control and data synchronization functions.

[0038] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
