Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a supplementary lighting device for a slit-lamp microscope. Background Technology

[0002] The slit-lamp microscope is an indispensable instrument in ophthalmic clinical diagnosis and treatment. It uses optical principles to enable detailed observation of ocular tissues and provides key evidence for the diagnosis of eye diseases.

[0003] In existing technologies, when observing iris texture or pupillary sphincter muscles, the curvature of the eye surface (such as the cornea) causes uneven light reflection, forming shadow areas, which affects observation and results in the loss of details. At the same time, some eye lesions (such as corneal edema and mild conjunctival hyperemia) are similar in color to the surrounding tissues, and slit light alone cannot accurately highlight the lesion features. Utility Model Content

[0004] Therefore, it is necessary to provide a supplementary lighting device for slit lamp microscopes to address the problems of detail loss and limited light source caused by insufficient light during the use of existing slit lamp microscopes.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A supplemental lighting device for a slit-lamp microscope includes a first housing and a second housing that cooperate with each other, forming a receiving cavity between the first housing and the second housing. A control module is installed in the receiving cavity. The control module is electrically connected to an LED light group. The LED light group includes a white LED light and two infrared LED lights symmetrically arranged relative to the white LED light.

[0007] The outer wall of the first housing is provided with grippers, which are used to hold the slit-lamp microscope. Under the control of the control module, a white LED light or two infrared LED lights are emitted to provide supplementary lighting during the acquisition of images by the slit-lamp microscope.

[0008] As a further improvement to the above technical solution:

[0009] The structure of the first shell is as follows: it includes a vertical shell part and a horizontal shell part connected thereto. The end face normal of the horizontal shell part is perpendicular to the end face normal of the vertical shell part, thereby forming an L-shaped shell body.

[0010] The inner side of the end face of the vertical housing part is provided with several positioning posts for installation with the second housing part, and the outer side of the end face of the vertical housing part is provided with grippers.

[0011] Several light-transmitting holes are spaced apart on the end face of the horizontal housing. A light-blocking plate is provided on the end face of the horizontal housing between two adjacent light-transmitting holes, thereby forming an LED lamp placement position above a single light-transmitting hole. The white LED lamp and two infrared LED lamps are placed in their respective LED lamp placement positions, and the light generated by the LED lamp group is transmitted through the corresponding light-transmitting holes.

[0012] The vertical housing, horizontal housing, and gripper are integrated into one structure.

[0013] Each positioning post is fitted with a fastening screw, which enables the first housing and the second housing to be fitted together.

[0014] A first filter is installed at the light-transmitting hole corresponding to the white LED light.

[0015] The first filter is installed by fitting it to the horizontal housing via a filter mounting plate;

[0016] Several positioning blocks are provided on the inner side of the end face of the horizontal housing part, and several positioning holes are provided on the end face of the filter mounting plate. The positioning holes are arranged in a one-to-one correspondence with the positioning blocks. By inserting the positioning blocks into the corresponding positioning holes, the filter mounting plate is fixed on the horizontal housing part.

[0017] A second filter is installed in the light-transmitting hole corresponding to a single infrared LED.

[0018] A groove is formed on the outer side of the end face of the horizontal housing portion, and the inner wall of the groove is inclined to form a slope, and the light-transmitting hole is arranged on the slope.

[0019] The gripper has the following structure: it includes two symmetrically arranged gripping arms, which are connected by a connecting part. Each gripping arm has an inwardly concave arc surface corresponding to the outer circular surface of the slit lamp microscope's support.

[0020] The control module includes a PCB board assembly, on which a Bluetooth component, a main control chip, and an LED light group are mounted. The PCB board assembly is electrically connected to a rechargeable battery.

[0021] The beneficial effects of this utility model are as follows:

[0022] This utility model has a compact and reasonable structure and is easy to operate. By setting up a first housing, a second housing, a gripper, a control module and an LED light group, it can provide supplementary lighting when the slit lamp microscope is working, thereby providing uniform background light, making up for areas that are difficult to cover by slit light and enhancing the illumination of the target area. At the same time, by setting up white light LEDs and infrared light LEDs, it can switch between different usage needs and effectively improve the contrast of the target area.

[0031] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0032] The structure and function of this utility model are as follows:

[0033] like Figures 1-5As shown, a supplementary lighting device for a slit-lamp microscope includes a first housing 1 and a second housing 2 that cooperate with each other, forming a receiving cavity between the first housing 1 and the second housing 2. A control module 4 is installed in the receiving cavity and is electrically connected to an LED light group. The LED light group includes a white LED 5 and two infrared LEDs 6 symmetrically arranged opposite the white LED 5. A gripper 3 is provided on the outer wall of the first housing 1, which clamps the microscope. Under the control of the control module 4, either the white LED 5 or the two infrared LEDs 6 emit light, thereby providing supplementary lighting during image acquisition by the slit-lamp microscope. By setting up the first housing 1, the second housing 2, the gripper 3, the control module 4, and the LED light group, supplementary lighting can be provided during the operation of the slit-lamp microscope, thereby providing uniform background light, compensating for areas that are difficult to cover by the slit light, and enhancing the illumination of the target area. At the same time, by setting up the white LED 5 and the infrared LEDs 6, switching can be made according to different usage needs, effectively improving the contrast of the target area.

[0034] like Figure 5 As shown, the structure of the first housing 1 is as follows: it includes a vertical housing part 101 and a horizontal housing part 102 connected thereto. The normal line of the end face of the horizontal housing part 102 is perpendicular to the normal line of the end face of the vertical housing part 101, thereby forming an L-shaped housing body. Several positioning posts 104 for cooperating with the second housing 2 are provided on the inner side of the end face of the vertical housing part 101, and a clamping claw 3 is provided on the outer side of the end face of the vertical housing part 101. Several light-transmitting holes 103 are spaced apart on the end face of the horizontal housing part 102. A light-blocking plate 106 is provided on the end face of the horizontal housing part 102 between two adjacent light-transmitting holes 103, thereby forming an LED lamp placement position above a single light-transmitting hole 103. A white LED lamp 5 and two infrared LED lamps 6 are placed in the corresponding LED lamp placement positions, and the light generated by the LED lamp group is transmitted through the corresponding light-transmitting hole 103. By setting up the light-blocking plate 106, interference between different light sources can be avoided; at the same time, the light-blocking plate 106 can stably support the circuit board on which the LED light group is installed, effectively making the internal layout of the supplementary lighting device compact.

[0035] In this utility model, three light-transmitting holes 103 are arranged at intervals along the horizontal direction. Among the three light-transmitting holes 103, the middle light-transmitting hole 103 corresponds to the white light LED lamp 5, and the two light-transmitting holes 103 on both sides correspond to the two infrared light LED lamps 6 respectively.

[0036] The vertical housing 101, the horizontal housing 102, and the gripper 3 are integrated into one structure. In this invention, the vertical housing 101, the horizontal housing 102, and the gripper 3 are manufactured using an injection molding process, resulting in high overall structural strength and improved reliability and service life of the supplementary lighting device.

[0037] A fastening screw 12 is installed inside a single positioning post 104, and the fastening screw 12 enables the mating installation between the first housing 1 and the second housing 2.

[0038] A first filter 7 is installed at the light-transmitting hole 103 corresponding to the white LED lamp 5. The first filter 7 is installed in conjunction with the horizontal housing part 102 via a filter mounting plate 9. Several positioning blocks 105 are provided on the inner side of the end face of the horizontal housing part 102, and several positioning holes 10 are provided on the end face of the filter mounting plate 9. The positioning holes 10 and positioning blocks 105 are arranged one-to-one. By inserting the positioning blocks 105 into the corresponding positioning holes 10, the filter mounting plate 9 is fixed on the horizontal housing part 102. By setting the filter mounting plate 9, the first filter 7 can be stably installed in the receiving cavity.

[0039] A second filter 8 is installed in the light-transmitting hole 103 corresponding to a single infrared LED 6. The light-transmitting hole 103 corresponding to a single infrared LED 6 is a stepped hole, and the second filter 8 is limited and fixed by the limiting step of the stepped hole itself.

[0040] By setting the first filter 7 and the second filter 8, stray light can be eliminated, and the interference of stray light on the image can be reduced, making the acquired image clearer and more accurate, and improving the contrast and clarity of the image; it can also ensure that the light emitted by the supplementary lighting device can accurately illuminate the observation area, reduce the interference of external light on image acquisition, and improve the reliability and stability of the detection.

[0041] A groove 13 is formed on the outer side of the end face of the horizontal housing part 102. The inner wall of the groove 13 is inclined to form a slope, and the light-transmitting hole 103 is arranged on the slope. By setting the groove 13 and the slope, the LED light group can illuminate the target area in a downward direction, so that the light covers the target area more comprehensively, reduces the generation of shadows, and helps to improve the image acquisition effect of the slit lamp microscope.

[0042] The gripper 3 has the following structure: it includes two symmetrically arranged gripping arms 301, which are connected by a connecting part 302. Each gripping arm 301 has a concave arc surface 303 corresponding to the outer circular surface of the slit-lamp microscope's support. The gripper 3 is used to cooperate with the slit-lamp microscope's support, eliminating the need for other auxiliary installation devices. The supplementary lighting device can be directly fixed to the slit-lamp microscope via the gripper 3, saving costs and facilitating use.

[0043] The control module 4 includes a PCB board assembly, on which a Bluetooth component, a main control chip, and an LED light assembly are mounted. The PCB board assembly is electrically connected to a rechargeable battery. In this invention, the rechargeable battery powers the LED light assembly, and a charging port is provided on the top wall of the second housing 2, allowing the rechargeable battery to be charged.

[0044] By setting up a Bluetooth component, the supplementary lighting device can connect to an industrial control computer or a smartphone via Bluetooth. This allows the industrial control computer or smartphone to control the white LED 5 or the infrared LED 6 to emit light, as well as adjust the brightness of the white LED 5 and the infrared LED 6.

[0045] In addition, a switch button 11 is installed on the side wall of the second housing 2, which controls the power on or off of the control module 4.

[0046] The working process of this utility model is as follows:

[0047] The supplementary lighting device is fixed to the support of the slit lamp microscope using the clamp 3, and the installation position of the supplementary lighting device is finely adjusted according to the location of the target area.

[0048] After adjustment, press switch button 11 to power on control module 4 and start the supplementary lighting device;

[0049] The supplementary lighting device is connected to a smartphone via Bluetooth. The smartphone controls the white LED 5 or the infrared LED 6 to emit light, and adjusts the brightness according to the usage requirements, thus providing supplementary lighting when working with a slit-lamp microscope.
