Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical devices, and specifically relates to an adjustable medical phototherapy lamp. Background Art
[0002] Medical phototherapy lamps, as a non-invasive treatment method, play a vital role in the modern medical field. They use light of specific wavelengths to have a positive impact on skin diseases, wound healing, pain relief, etc., such as promoting cell proliferation and differentiation, inhibiting inflammatory responses, and improving local blood circulation. However, traditional medical phototherapy lamps have some inherent limitations and shortcomings in practical applications.
[0003] First, the light source irradiation angle of existing medical phototherapy lamps is often fixed and cannot flexibly adapt to the different curvatures and depths of various parts of the patient's body, which can easily lead to uneven lighting and even blind spots. For example, when treating complex curved surfaces of the face or torso, the fixed light source layout may not effectively cover all areas that need treatment, thereby affecting the adequacy and consistency of the phototherapy effect. Secondly, many handheld medical phototherapy lamps were not fully designed with ergonomic factors in mind. The handle structure is rigid and the holding method is single. During long-term operation, medical staff may suffer from hand fatigue due to the fixed holding posture, which reduces work efficiency and increases safety risks caused by improper operation.
[0004] In view of the above problems, researchers at home and abroad have been exploring the design of improved medical phototherapy lamps, striving to solve the problems of limited light source irradiation range and low operating comfort through technological innovation. However, although some products on the market have tried to use technology that can adjust the direction of the light source, its adjustment method is still not flexible and comprehensive enough, especially in the three-dimensional space to fully adjust the position of the light source without blind spots to meet various clinical needs. There are still great challenges. Utility Model Content
[0005] In view of this, the utility model provides an adjustable medical phototherapy lamp, which can freely adjust the angle in three-dimensional space and has an ergonomic handle structure, thereby alleviating the inconvenience of medical staff during long-term use.
[0006] The utility model is achieved in this way:
[0007] The utility model provides an adjustable medical phototherapy lamp, which includes a light source assembly, a rotating bracket, and a handle, wherein the light source assembly is mounted on the rotating bracket, and the rotating bracket includes a first rotating shaft, a second rotating shaft, and a third rotating shaft connected to each other, which respectively control the left and right rotation, up and down swing, and pitch tilt of the light source assembly, and the light source assembly includes a central light source and a light bulb, and light bulbs are arranged at both ends of the first rotating shaft, the second rotating shaft, and the third rotating shaft; the handle is fixedly connected to the rotating bracket;
[0008] The handle adopts a streamlined design, and the surface is provided with anti-slip textures arranged in a linear array.
[0009] The overall shape of the handle follows the law of low wind resistance or the natural movement trajectory of the hand, which is manifested in that the transition curve from one end to the other is continuous and differentiable, and conforms to the principle of optimal streamline distribution. In addition, the natural palm curve structure of the ergonomic handle is to ensure that the shape of the handle can closely fit the three-dimensional contour of the human hand under different gripping postures, so that the user can maintain the most natural and comfortable hand muscle and bone state when gripping, reduce fatigue and enhance grip stability.
[0010] On the basis of the above technical solution, the adjustable medical phototherapy lamp of the utility model can also be improved as follows:
[0011] Among them, the first rotation axis is located in the horizontal dimension of the three-dimensional space, the second rotation axis is perpendicular to the first rotation axis and is located in the longitudinal dimension of the three-dimensional space, and the third rotation axis is perpendicular to the plane formed by the first rotation axis and the second rotation axis.
[0012] Furthermore, the first rotation axis is arranged at the bottom of the central light source, the second rotation axis is connected to the central part of the central light source, and the third rotation axis is located at the side of the central light source.
[0013] The first rotation axis (horizontal axis) is arranged at the bottom of the central light source and is pivotally connected thereto, allowing the light source assembly to rotate 360° in the left and right directions without dead angles.
[0014] The second rotation axis (pitch axis): It is usually perpendicular to the first rotation axis and connected to the center of the central light source. By rotating the second rotation axis, the light source assembly can be swung up and down, and the irradiation height of the light source can be adjusted to cover the treatment area at different angles from bottom to top.
[0015] The third rotation axis (yaw axis or roll axis): perpendicular to the plane defined by the first rotation axis and the second rotation axis, also connected to the core structure of the light source assembly, controls the light source assembly to tilt forward and backward or rotate around its own axis to adapt to the patient's body curve and multi-directional irradiation requirements.
[0016] Furthermore, the first rotating shaft is provided with a gear transmission mechanism, including an input gear, an output gear, and a gear positioning and limiting device, wherein the input gear is connected to the handle, and the output gear is connected to the first rotating shaft, and torque is transmitted through gear meshing.
[0017] The beneficial effect of adopting the above-mentioned improvement scheme is that the gear transmission mechanism adjusts the left and right rotation angle range to 0° to 360°.
[0018] Furthermore, an electric push rod is installed on the second rotating shaft to drive the light source assembly to swing up and down, and the up and down swing angle range is adjusted to be -45° to +45°.
[0019] Furthermore, the electric push rod includes a cam-linkage mechanism, an angle sensor and a brake, the cam-linkage mechanism is used to rotate the second rotating shaft, and the brake is used to fix the second rotating shaft.
[0020] Furthermore, the third rotation axis adopts a damping rotation structure, and the damping rotation structure includes a damping rotation axis and a spring. The damping rotation structure adjusts the pitch tilt range of the light source assembly to cover -20° to +70°.
[0021] Furthermore, the streamlined design specifically refers to a cross section of the handle that presents a continuously changing curve shape along the length direction, including one of the non-straight curves of an ellipse or a parabola.
[0022] Furthermore, the light source assembly also includes a heat dissipation module, and the heat dissipation module includes a heat sink and a fan.
[0023] Furthermore, the handle is made of one of polycarbonate, polypropylene and stainless steel, and the surface is covered with a layer of one of rubber and silicone materials.
[0024] Compared with the prior art, the adjustable medical phototherapy lamp provided by the utility model has the following beneficial effects:
[0025] All-round irradiation without blind spots: By adopting a three-dimensional degree of freedom rotating bracket design, the light source component can be flexibly adjusted at multiple angles, left and right, up and down, and in pitch. The first rotation axis (horizontal axis) solves the problem of left and right movement of the light source, effectively expanding the treatment range; the second rotation axis (vertical axis) enables the light source to be adjusted up and down according to the patient's body height or lesion location, ensuring that the patient's parts at different depths can be fully irradiated; and the third rotation axis (roll axis) allows the light source to adapt to various complex curved skin areas, overcoming the coverage blind area problem that traditional fixed phototherapy lamps cannot handle. This feature greatly improves the accuracy and comprehensiveness of phototherapy, helping to improve treatment efficiency and disease recovery speed;
[0026] Ergonomically optimized handle design: The handle of this utility model follows the principles of ergonomics and is carefully designed as a streamlined structure with an anti-slip texture on the surface, which enhances the comfort and stability of holding. More importantly, the handle allows medical staff to flexibly adjust the holding angle according to actual operation needs, reducing the pressure and fatigue of hand muscles during long-term use. This humanized design not only improves the job satisfaction of medical staff, but also indirectly improves the safety and accuracy of the diagnosis and treatment process.
