Description

Technical Field

[0001] This utility model relates to the field of vision testing technology, and in particular to a strabismus measuring instrument. Background Technology

[0002] Strabismus is a common clinical eye disease affecting 2% to 5% of the population. When using both eyes to see, strabismus patients often experience impaired coordination and alignment, resulting in misalignment of the eyes. A strabismus measuring instrument is an important piece of equipment in ophthalmology, used to accurately measure the degree of eye deviation in strabismus patients.

[0003] During strabismus testing, it is crucial to ensure the patient's head remains in a stable and appropriate position to guarantee the accuracy of the measurement data. However, current strabismus measuring devices on the market have several shortcomings in their facial fixation mechanisms. Firstly, most fixation devices are difficult to disassemble quickly after installation, which is extremely inconvenient in practical use. For example, when cleaning, disinfecting, or temporarily replacing parts of different sizes is required, the cumbersome disassembly process consumes a significant amount of time and effort. Secondly, after a period of use, some vulnerable components of these fixation devices often fail. Due to their structural design, it is difficult to replace damaged parts individually; usually, the entire device must be replaced, increasing operating costs and wasting resources, thus requiring urgent improvement and optimization.

[0004] Therefore, there is a need for improvements to strabismus measurement instruments in the existing technology. Utility Model Content

[0035] like Figure 1 The image shows an improved strabismus measuring instrument according to the present invention, comprising:

[0036] The measuring instrument body 10 has a measuring window 11 on one side;

[0037] The forehead support structure 20 is located above the measuring window 11 and is detachably connected to the measuring instrument body 10.

[0038] The jaw support structure 30 is detachably connected to the measuring instrument body 10. The jaw support structure 30 is extendable between a first position and a second position in the vertical direction. When in the first position, the jaw support structure 30 is located below the measuring window 11. When in the second position, the jaw support structure 30 is located directly in front of the measuring window 11.

[0039] Furthermore, such as Figure 2 This is a schematic diagram of an embodiment of the forehead support structure provided by this utility model. The forehead support structure 20 includes a connecting seat 22 and a soft adhesive block 23. The measuring instrument body 10 has a mounting base 21. The first side of the connecting seat 22 is detachably connected to the mounting base 21, and the second side is detachably connected to the soft adhesive block 23.

[0040] In some embodiments, the mounting base 21 has a plurality of sockets 220, and the first side of the connector 22 has a plurality of pins 220 that match the size of the sockets 210 so that the connector 22 can be detachably connected to the mounting base 21. The second side of the connector 22 has a groove in which a soft adhesive block 23 snaps into the groove.

[0041] In other embodiments, the connector 22 and the mounting base 21 are magnetically connected, and the soft adhesive block 23 is adhesively connected to the connector 22. Preferably, a ring magnet is provided inside the mounting base 21, and a magnetic metal sheet that can be tightly attracted to the ring magnet is installed on the first side of the connector 22. This connection method is extremely simple to operate; simply bring the connector close to the mounting base, and it can be quickly attracted and fixed by magnetic force. Moreover, during disassembly, only a certain external force needs to be applied to pull the connector apart. Magnetic connection reduces wear on mechanical parts because there is no physical friction process of plugging and unplugging, and the service life of the connector and the mounting base may be longer. At the same time, its connection structure is relatively simple and the cost is low, which can simplify the overall structure of the equipment to a certain extent.

[0042] Furthermore, those skilled in the art should understand that the connection method between the mounting base 21 and the connecting seat 22 is not limited to the above methods.

[0043] For example, it can also be a snap-fit ​​connection, with elastic snaps on the edge of the mounting base and a matching groove on the first side of the connector. For instance, the mounting base has several elastic plastic snaps on its edge, with the snap heads at a slight angle to facilitate opening when the connector is inserted. The first side of the connector has a corresponding annular groove; when the connector is inserted into the mounting base, the snaps engage with the groove under the action of elastic restoring force, thus achieving the connection.

[0044] For example, a quick-release bolt connection can also be used. Corresponding screw holes are provided on the mounting base and connector, and a specially designed quick-release bolt is used for connection. This bolt can have a quick-rotate handle or a special nut structure, such as a wing nut. When connection is needed, simply pass the bolt through the screw holes in the mounting base and connector, and then tighten the wing nut to complete the connection.

[0045] Furthermore, the forehead support structure 20 can be detachably and slidably connected to the measuring instrument body 10. The forehead support structure 20 includes a connecting seat 22 and a soft fitting block 23. The measuring instrument body 10 has a grooved track. The first side of the connecting seat 22 has multiple pins that match the grooved track, allowing the connecting seat to be detachably and slidably connected on the grooved track. The soft fitting block 23 is connected to the second side of the connecting seat 22. This slidable design has the advantage that different patients have different head sizes and shapes. When the forehead support is slidably connected to the measuring instrument body, its position can be flexibly adjusted according to the width and height of the patient's forehead. For example, for patients with wider foreheads, the forehead support can be slid to the sides to better fit the patient's forehead and provide stable support. For patients with narrower foreheads, the forehead support can also be slid inwards to a suitable position, ensuring that each patient receives a comfortable and stable head fixation effect. This helps improve the device's adaptability to different populations. The forehead support can slide and adjust as the head position changes, ensuring that the head remains stably fixed.

[0046] Preferably, the fitting block for the forehead support structure is concave arc-shaped. This can be further extended to allow the forehead support structure to slide horizontally relative to the main unit casing, and also to swing left and right within a certain angle range in the vertical measurement window direction, in conjunction with the jaw support structure to achieve fine-tuning of the subject's head movement from side to side, with the swing angle range being [-10°, +10°].

[0047] Furthermore, such as Figures 3-4 The diagram shown is a schematic of an embodiment of the jaw support structure and base structure. The jaw support structure 30 includes a base 31, a lifting mechanism 32, and two symmetrically arranged fixing mechanisms 33. The top of the lifting mechanism 32 is fixedly connected to the base 31. The fixing mechanism 33 includes a connecting plate 330 and a first fixing part 331 and a second fixing part 332 extending vertically in the opposite direction along the plane of the connecting plate 330. The two symmetrically arranged first fixing parts 331 engage with the lifting mechanism 32, and the second fixing parts 332 are detachably connected to the measuring instrument body 10.

[0048] In some embodiments, the second fixing part 332 is detachably connected to the measuring instrument body 10 by means of: snap-fit ​​connection, bolt fixing connection, and quick-release pin connection.

[0049] Specifically, the snap-fit ​​connection method involves providing a slot on the main body 10 of the measuring instrument that matches the second fixing part 332. The slot has a certain elastic opening. The end of the second fixing part 332 is designed with a specific shape, such as a protruding locking block structure. When the second fixing part 332 is inserted into the slot, the elastic wall of the slot will expand outward. After the locking block is fully inserted, the slot wall tightly locks the locking block under its own elastic restoring force, thereby achieving a quick and stable connection. This connection method is simple to operate, requiring no additional tools. The connection and disassembly of the second fixing part 332 and the main body 10 of the measuring instrument can be completed by manual insertion and removal, which can effectively improve the assembly and maintenance efficiency of the equipment. At the same time, the snap-fit ​​structure is relatively simple, low in cost, and easy to manufacture and replace later.

[0050] Specifically, the bolt fixing method involves drilling screw holes at the corresponding connection points of the second fixing part 332 and the measuring instrument body 10, passing the bolt through these holes sequentially, and then tightening it with a nut. Standard hexagonal bolts can be selected, and appropriate lock nuts can be used to ensure a secure connection. During installation, first align the second fixing part 332 with the connection position on the measuring instrument body 10, then insert the bolt and tighten the nut to ensure a tight connection. This connection method offers high strength and stability, can withstand significant external forces, and is suitable for applications where the equipment needs to withstand substantial vibration or requires precise positioning.

[0051] Furthermore, such as Figure 4 As shown, the base 31 includes a support portion 310 and a limiting portion 311 extending vertically outward from the edge of the support portion 310. The support portion 310 has an ergonomic curved design.

[0052] Preferably, a flexible buffer block 312 is provided on the support portion 310. This flexible buffer block 312 can be an ergonomically concave support that conforms to the examinee's jaw, and can be made of soft materials such as silicone or rubber. Furthermore, the jaw support can also achieve circular swing within a certain angle range in the horizontal direction to allow for fine-tuning of the examinee's head movement from side to side. The swing angle range is [-10°, +10°]. The jaw support structure can also be electrically powered.

[0053] Preferably, the measuring instrument may further include two cheekbone supports, symmetrically arranged on both sides of the measuring window and detachably connected to the main body of the measuring instrument. Furthermore, the cheekbone supports may be rotatably connected to the main frame; for example, a motor structure facilitates adjustment of the cheekbone supports' left and right rotation, and the shape of the cheekbone supports adapts to the shape of the face. The combination of the jaw support structure, forehead support structure, and cheekbone support structure provides head support for the examinee, defines the head measurement position and angle, and ensures measurement consistency.

[0054] Furthermore, the measuring instrument's main body comprises an upper main unit housing and a lower main unit base. The image processing system, housed within the main unit housing, is used to capture images of the subject's eyes and calculate eye misalignment. The power supply unit, housed within the main unit base, includes a power module, a filter module, a hub, and control circuitry. Additionally, a heat dissipation vent can be provided on the side of the main unit base. Dividing the main frame into the housing and base facilitates component installation, debugging, and maintenance.
