Description

Technical Field

[0001] This utility model relates to the field of medical testing equipment technology, specifically to an image acquisition device. Background Technology

[0002] In traditional Chinese medicine, observation is a crucial method for diagnosing diseases, with facial complexion and tongue appearance being particularly important. Changes in facial complexion are considered an external manifestation of the state of Qi and blood, while the tongue appearance serves as a direct "window" reflecting changes in internal organs. With the rapid development of artificial intelligence (AI) technology, applying AI to tongue and facial diagnosis in TCM has become a research hotspot. Through image recognition technology, AI can perform more precise analysis of tongue appearance, reducing human interference and improving the objectivity and accuracy of diagnosis. Therefore, the demand for tongue and facial image acquisition in modern medicine is increasing daily.

[0003] Currently, the most common image acquisition devices on the market fall into two categories: small, handheld scanners and large, fully automated scanners, such as the publicly disclosed 3D scalp scanner (publication number: CN217772503U), which can quickly and accurately analyze scalp conditions. While handheld scanners are convenient to use, they require medical personnel to hold them for extended periods, consuming considerable energy. Large, fully automated scanners, on the other hand, are expensive, hindering widespread adoption. Therefore, there is an urgent need for an image acquisition device that is cost-effective and does not require manual handling. Utility Model Content

[0004] This invention provides an image acquisition device that can solve the technical problem that existing image acquisition devices cannot simultaneously save manpower and reduce costs.

[0005] This application provides the following technical solution:

[0006] An image acquisition device includes a base, a lifting assembly, a support assembly, an illumination assembly, and a scanning assembly. The support assembly includes a first support, a second support, and a third support. The two ends of the first support are rotatably connected to one end of the lifting assembly and one end of the second support, respectively. The other end of the second support is rotatably connected to one end of the third support, and the other end of the third support is detachably fixedly connected to the scanning assembly. The illumination assembly includes a searchlight and a flexible tube fixedly connected to the support assembly. A photosensitive sensor electrically connected to the searchlight is fixedly installed on the searchlight. The base includes a support column, several tripods vertically fixed around the support column, a connecting frame fixedly installed between two adjacent tripods, and feet fixedly installed at the bottom of the tripods.

[0007] Beneficial effects:

[0008] 1. Saves manpower and improves work efficiency: This device can be used in conjunction with existing small scanners, saving manpower while improving equipment utilization and applicability. Specifically, through the linkage design of the lifting and support components, users can adjust the height of the scanning component by rotating the dial, eliminating the need to manually hold the scanner for extended periods, reducing the workload of medical staff. The flexible adjustment method makes operation more convenient, and the addition of a lighting component further improves work efficiency and image quality.

[0009] 2. Low manufacturing cost and economical: Compared to large scanning equipment, the manufacturing cost is lower. Specifically, the device adopts a modular design, including a base, lifting assembly, support assembly, lighting assembly, and scanning assembly. Each part can be manufactured and assembled independently, reducing the overall manufacturing cost and making it suitable for widespread application in medical projects.

[0010] 3. Strong structural stability and not easy to tip over: This device integrates multiple components such as lighting, shooting, angle and height position adjustment. The stability of the base structure is the key to ensuring the safe use of the device. The base in this solution includes a support column, several tripods fixedly set vertically around the support column, a connecting frame fixedly set between two adjacent tripods, and a support foot fixedly set at the bottom of the tripod. The stability characteristics of the triangular structure provide relatively stable support and fixation for the entire device.

[0011] Furthermore, as an improvement, the lifting assembly includes a lead screw fixedly connected to the bracket assembly, a rotating disk threadedly connected to the lead screw, and a support disk rotatably connected to the rotating disk, wherein the support disk is fixedly connected to the base.

[0012] Beneficial effects: Users can easily adjust the height of the scanning component by manually rotating the turntable, without complicated operating procedures, making it very convenient to use. The design of the lead screw and turntable provides more precise height adjustment, ensuring that the scanning component can be accurately aligned with the area of ​​the patient to be scanned, while the fixed connection between the support plate and the base ensures the stability of the entire lifting assembly, avoiding shaking or displacement caused by external forces, and improving the reliability of the equipment.

[0013] Furthermore, as an improvement, a spring is fixedly installed between the first bracket and the second bracket.

[0014] Beneficial effects: The spring mechanism provides damping to the movement of the first or second support, limiting the maximum range of motion between the two supports and preventing them from exceeding safe limits due to excessive movement. This results in smoother operation and avoids accidental damage caused by rapid or forceful movements. Simultaneously, the damping effect of the spring also helps to precisely control the angle adjustment of the support, ensuring that the scanning assembly can accurately align with the target area, thus improving scanning accuracy and reliability.

[0015] Furthermore, as an improvement, the support assembly also includes a hinge for rotatably connecting the first support and the second support, wherein the shaped hose is fixedly connected to the hinge.

[0016] Beneficial effects: The hinge is used to rotatably connect the first and second brackets, ensuring flexible rotation between the two brackets. It also provides installation conditions for the shaping hose. The shaping hose allows the searchlight to bend arbitrarily and fix its direction, ensuring that the lighting components can accurately illuminate the area to be scanned, thus improving the imaging effect.

[0017] Furthermore, as an improvement, the photosensitive sensor is a photoresistor, and the lighting assembly also includes a battery that provides power to the searchlight, the battery being electrically connected to the photoresistor.

[0018] Beneficial effects: The photoresistor allows the illumination component to automatically adjust the spotlight intensity, ensuring appropriate illumination under different lighting conditions, thus improving scanning accuracy and quality. The elimination of manual spotlight brightness adjustment simplifies operation and enhances ease of use. Attached Figure Description

[0023] The following detailed description illustrates the specific implementation method:

[0024] The markings in the accompanying drawings include: base 1, support column 11, tripod 12, connecting frame 13, support leg 14, lifting assembly 2, lead screw 21, guide groove 211, rotating disk 22, support disk 23, ball bearing 24, protrusion 25, bracket assembly 3, first bracket 31, second bracket 32, third bracket 33, connecting seat 34, hinge 1 35, hinge 2 36, hinge 3 37, spring 38, lighting assembly 4, searchlight 41, shaping hose 42, photosensitive sensor 43, battery 44, scanning assembly 5.

[0025] Example 1

[0026] like Figures 1-4 As shown, an image acquisition device includes a base 1, a lifting assembly 2, a support assembly 3, an illumination assembly 4, and a scanning assembly 5.

[0027] The base 1 includes a support column 11, three tripods 12 fixedly arranged vertically around the support column 11, a connecting frame 13 fixedly arranged between the bottoms of two adjacent tripods 12, and a support leg 14 fixedly arranged at the bottom of the tripod 12. The aforementioned fixing arrangements all adopt fixing connection methods such as screws and bolts. The base 1 provides stable support for the image acquisition device. No matter how the position and center of gravity of the lighting component 4 and the scanning component 5 change, the overall stability of the device can be guaranteed, avoiding safety problems caused by the device tipping over during the adjustment process.

[0028] The lifting assembly 2 includes a lead screw 21, a rotating disk 22 threadedly connected to the lead screw 21, and a support disk 23 rotatably connected to the rotating disk 22. Specifically, the support disk 23 is fixedly installed on the top of the support column 11 with screws. The rotating disk 22 is located on the support disk 23. A ball bearing 24 for rotatably connecting the rotating disk 22 and the support disk 23 is fixedly installed between the rotating disk 22 and the support disk 23. The bottom of the ball bearing 24 is fixedly connected to the rotating disk 22 with screws. The balls on the ball bearing 24 are in close contact with the bottom of the rotating disk 22, so that the rotating disk 22 can rotate relative to the support disk 23 around the lead screw 21. At the same time, a protrusion 25 is fixedly installed in the central through hole of the support disk 23 with screws. A vertical guide groove 211 is fixedly opened on the lead screw 21. The aforementioned protrusion 25 is inserted into the guide groove 211 to form a directional sliding fit. When the rotating disk 22 is rotated in the forward and reverse directions, the lead screw 21 will be driven to drive the bracket assembly 3, the lighting assembly 4, and the scanning assembly 5 to rise and fall as a whole.

[0029] The support assembly 3 includes a first support 31, a second support 32, a third support 33, a connecting seat 34 located between the lead screw 21 and the first support 31, a hinge 35, a hinge 36 located between the first support 31 and the second support 32, and a hinge 37 located between the second support 32 and the third support 33. Both ends of the first support 31 are hinged to the connecting seat 34 fixedly connected to the top of the lead screw 21 and one end of the second support 32, respectively. The other end of the second support 32 is hinged to one end of the third support 33. The other end of the third support 33 is detachably fixed to the scanning assembly 5 via bolts and screws. A spring 38 is fixedly installed between the first support 31 and the second support 32 by welding. The spring 38 is configured to provide damping when moving the first support 31 or the second support 32 (to adjust the specific position of the scanning assembly 5) to limit the maximum range of motion between the two supports, preventing damage or safety issues caused by excessive movement.

[0030] The lighting assembly 4 includes a searchlight 41 and a flexible tube 42 fixedly connected to the hinge 36. The flexible tube 42 is a serpentine tube that can be bent arbitrarily and has a defined direction. A photosensitive sensor 43, electrically connected to the searchlight 41, is fixedly installed on the searchlight 41. In this embodiment, the photosensitive sensor 43 is a photoresistor. The lighting assembly 4 also includes a battery 44 that provides power to the searchlight 41. The battery 44 is electrically connected to the photoresistor. The photoresistor enables the lighting assembly 4 to automatically adjust the brightness of the searchlight 41 by monitoring the brightness of the external environment.

[0031] Scanning component 5 uses a camera equipped with a Bluetooth module to enable photo or video recording via mobile phones, remote controls, and other terminals.

[0032] The specific application process is as follows:

[0033] In use, the scanning component 5 is fixedly mounted on the third bracket 33 with bolts and screws, and the lens is adjusted to be aimed at the part of the patient's body that needs to be scanned (such as the scalp). During the adjustment process, the scanning component 5 can be raised or lowered by rotating the rotating disk 22 in the forward and reverse directions, thereby driving the lead screw 21. Alternatively, the position of the scanning component 5 can be adjusted by loosening the screws of the first hinge 35, the second hinge 36, and the third hinge 37 and then appropriately moving the first bracket 31, the second bracket 32, or the third bracket 33.

[0034] This image acquisition device, through its modular design and flexible adjustment mechanism, allows for integration with existing small scanners, significantly saving manpower and improving work efficiency. Simultaneously, its relatively low manufacturing cost makes it economical and suitable for widespread application. This design not only meets the medical field's demand for efficient and convenient image acquisition equipment but also provides medical institutions with an economically feasible solution.

[0035] Example 2

[0036] The difference between this embodiment and embodiment one is that the support leg 14 in embodiment one is replaced with a universal wheel with a locking function, thereby increasing the flexible movement function of the image acquisition device.
