Description

Technical Field

[0001] This utility model relates to the technical field of portable brackets for Wood's lamp inspection, and in particular to a portable bracket for Wood's lamp inspection. Background Technology

[0002] Wood's lamp is a medical diagnostic tool that uses ultraviolet light (mainly at a wavelength of 365nm) to assist in the diagnosis of skin diseases. Its principle is based on the different fluorescent reactions produced by the affected skin, hair, or mucous membranes under ultraviolet light (e.g., bright green fluorescence for fungal infections, bluish-white fluorescence for vitiligo lesions). This helps doctors quickly identify pigmentary disorders (such as vitiligo and tinea versicolor), infectious diseases (such as tinea capitis), and certain skin tumors. It is non-invasive, rapid, and visually intuitive, making it an important auxiliary tool in dermatological clinical diagnosis. The portable stand for Wood's lamp examination is a movable support device specifically designed for Wood's lamp examination.

[0003] Most existing portable stands are primarily designed to hold a Wood's lamp in place, and their angle adjustment capabilities are limited. When examining irregular areas of a patient's body, such as the inside of the elbow or behind the knee, traditional stands cannot be quickly and flexibly adjusted to the appropriate angle, resulting in low examination efficiency. Therefore, we propose a portable stand for Wood's lamp examination. Utility Model Content

[0012] As a preferred embodiment, a threaded rod is fixedly installed on the outer wall of the rotating sleeve, and a threaded sleeve rod is threadedly connected to the outer wall of the threaded rod, the size of which is adapted to the storage groove.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. Through the installation and adjustment mechanism, the turntable is connected to the bearing via a rotating shaft, allowing the turntable to rotate flexibly on the support plate. It can be freely adjusted in the horizontal direction of 360 degrees. By locking and releasing the buckle, the position of the Wood's lamp can be quickly locked and unlocked to meet the needs of the Wood's lamp illumination direction in different examination scenarios. At the same time, the mounting bracket is connected to the rotating ball and connecting rod through the spherical cavity.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see the appendix Figure 1 - Appendix Figure 7 A portable bracket for Wood's lamp inspection includes a support plate 1 and an installation adjustment mechanism 4 disposed on the plate 1. A support mechanism 5 is disposed below the support plate 1. The installation adjustment mechanism 4 includes a turntable 401 and a limiting member 411. The turntable 401 is connected to a bearing 403 via a rotating shaft 402. Mounting brackets 404 are fixedly installed on the upper surface of the turntable 401 near both sides. Both sets of mounting brackets 404 are connected to a rotating ball 407 and a connecting rod 408 via a spherical cavity 405. Threaded limiting sleeves 410 are threadedly connected to the outer walls of both sets of mounting brackets 404. A lamp holder 409 for mounting Wood's lamp is fixedly installed at one opposite end of the two sets of connecting rods 408. A sliding groove 412 is provided inside the limiting member 411. The sliding groove 412 is connected to a strong spring 414 and a sliding block 416 via a sliding column 413. The sliding block 416 is connected to a limiting rod 418 and a retaining ring 419 via a limiting bracket 417.

[0027] A rotating groove 2 is provided at the center of the surface of the support plate 1, and four sets of storage grooves 3 are provided at the bottom of the support plate 1 near the two sides.

[0028] The bearing 403 is fixedly installed inside the rotating groove 2, and the rotating shaft 402 is fixedly installed at the center of the lower surface of the turntable 401. The rotating shaft 402 is fixedly installed on the inner ring of the bearing 403.

[0029] The rotating groove 2 is used for the installation of the bearing 403, serving as the rotational basis for the entire installation and adjustment mechanism 4. The storage groove 3 is used for the installation and storage of the support mechanism 5.

[0030] The spherical cavity 405 is fixedly installed on the inner side of the mounting bracket 404. An opening 406 is provided on the outer wall of the open end of the spherical cavity 405. The rotating ball 407 is rotatably connected inside the spherical cavity 405. The connecting rod 408 is fixedly installed on the outer wall of the rotating ball 407.

[0031] The opening 406 allows the spherical cavity 405 to deform when the threaded limit sleeve 410 is tightened, fixing the internal rotating ball 407. The connection structures between the bearing 403 and the rotating shaft 402, the spherical cavity 405 and the rotating ball 407, etc., all adopt mature mechanical connection principles, with relatively simple manufacturing processes, easy production and processing, and high stability and low failure rate during use, reducing equipment maintenance costs, extending the service life of the bracket, and having good economic and practical advantages.

[0032] The sliding column 413 is fixedly installed inside the slide groove 412, the strong spring 414 is sleeved on the outer wall of the sliding column 413, and the upper end of the limiting member 411 is provided with a limiting groove 415.

[0033] The sliding block 416 is slidably connected to the outer wall of the sliding column 413. The bottom of the limiting frame 417 is fixedly installed on the upper end of the sliding block 416. The outer wall of the limiting frame 417 is slidably connected to the inside of the limiting groove 415. The buckle 419 is fixedly installed on the upper end of the limiting frame 417. The limiting rod 418 is fixedly installed on the bottom of one side of the upper end of the limiting frame 417.

[0034] Both the sliding block 416 and the strong spring 414 are on the outer wall of the sliding column 413. The sliding block 416 is at the lower end of the strong spring 414. When the strong spring 414 is in the compressed state, the limiting rod 418 is separated from the turntable 401.

[0035] Specifically, the turntable 401 is connected to the bearing 403 via the rotating shaft 402, allowing the turntable 401 to rotate flexibly on the support plate 1 and achieve free adjustment in the horizontal direction of 360 degrees. By locking and releasing the buckle 419, the position of the Wood's lamp can be quickly locked and unlocked to meet the needs of the Wood's lamp illumination direction in different examination scenarios. At the same time, the mounting bracket 404 is connected to the rotating ball 407 and the connecting rod 408 via the spherical cavity 405. This structure allows the lamp holder 409 to be flipped and tilted at multiple angles in the vertical plane, realizing the all-round angle adjustment of the Wood's lamp in space. It can accurately irradiate and examine various parts of the patient's body, improving the accuracy and comprehensiveness of the examination.

[0036] Please see the appendix Figure 1 and attached Figure 8 The support mechanism 5 includes four sets of fixed rods 501. The four sets of fixed rods 501 are fixedly installed in four sets of storage slots 3 respectively. The outer walls of the four sets of fixed rods 501 are rotatably connected with rotating sleeves 502.

[0037] The rotation between the rotating sleeve 502 and the fixed rod 501 is damped, and the two will not rotate relative to each other without the action of external human force.

[0038] A threaded rod 503 is fixedly installed on the outer wall of the rotating sleeve 502. A threaded sleeve rod 504 is threadedly connected to the outer wall of the threaded rod 503. The size of the threaded sleeve rod 504 is adapted to the storage groove 3.

[0039] The threaded sleeve 504 can rotate along the outer thread of the threaded rod 503 to adjust the height. When stored, the threaded sleeve 504 can be completely locked in the storage slot 3 and will not fall out.

[0040] Specifically, the threaded connection design between the threaded rod 503 and the threaded sleeve rod 504 allows for precise adjustment of the overall height of the support by rotating the threaded sleeve rod 504. This enables quick and convenient adjustment to a suitable height, whether for the operational needs of medical staff of different heights or to meet the lighting height requirements during examinations of different parts of the patient. The size of the threaded sleeve rod 504 is compatible with the storage slot 3. When not in use, rotating the sleeve 502 causes the threaded rod 503 to rotate and fold into the storage slot 3, allowing the entire support mechanism 5 to be completely stored at the bottom of the support plate 1, further reducing the storage volume of the support. This design not only facilitates storage but also makes it easy for medical staff to carry. When it is necessary to move the examination location, the support can be quickly folded up, saving space and improving work efficiency.

[0041] The working principle of this utility model is as follows: This utility model is a portable bracket for Wood's lamp examination. When the bracket is brought to the examination site, firstly, the rotating sleeve 502 is rotated, which causes the threaded rod 503 to rotate around the fixed rod 501. By rotating the threaded sleeve rod 504, the position of the threaded sleeve rod 504 on the threaded rod 503 is adjusted, thereby adjusting the overall height of the bracket to meet the operating height requirements of medical staff and the illumination height of the examination site.

[0042] The Wood's lamp is mounted on the lamp holder 409. Rotating the ball 407 within the spherical cavity 405 causes the connecting rod 408 and the lamp holder 409 to rotate and tilt at multiple angles in the vertical plane, initially adjusting the illumination angle of the Wood's lamp. The turntable 401 is then rotated via the shaft 402 within the bearing 403, achieving a 360-degree horizontal adjustment to further adjust the illumination direction of the Wood's lamp. After adjusting the angle and direction of the Wood's lamp, the threaded limiting sleeve 410 on the outer wall of the mounting bracket 404 is tightened. The threaded limiting sleeve 410 limits and fixes the rotating ball 407, preventing the Wood's lamp angle from shifting during inspection.

[0043] According to the actual needs of the inspection, if it is necessary to temporarily adjust the position of the Wood's lamp, pull the buckle 419. The buckle 419 drives the limit bracket 417 and the sliding block 416 to slide on the sliding column 413, compressing the strong spring 414, so that the limit rod 418 is disengaged from the limit state, and the position of the Wood's lamp can be quickly moved. After the adjustment is completed, release the buckle 419. Under the action of the strong spring 414, the limit rod 418 is locked back into the limit position, realizing the locking of the position of the Wood's lamp.

[0044] After the inspection, first remove the Wood lamp from the lamp holder 409, rotate the threaded sleeve 504 until the threaded rod 503 is completely wrapped, rotate the rotating sleeve 502 to make the threaded rod 503 rotate and fold into the storage groove 3, and completely store the four sets of fixing rods 501 and related components in the storage groove 3 at the bottom of the support plate 1, reducing the size of the bracket and making it easy to store and carry.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
