Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an adjustable-angle examination light. Background Technology

[0002] Medical examination lights are professional devices used in medical environments to provide high-brightness, shadowless illumination. They are widely used in operating rooms, emergency departments, dental departments, gynecology departments, and other settings. In dental departments, examination lights need to ensure that doctors have a clear view inside the patient's mouth. Existing dental medical examination lights are usually high-brightness to ensure that the deep parts of the patient's mouth are clearly visible without shadows, reducing the shadows cast by teeth and tongue in the cavity.

[0003] During oral treatment, doctors need to point the examination lamp at the patient's mouth 50 to 80 centimeters away to ensure that the light can illuminate the patient's mouth. In winter, the overall ambient temperature is low during oral surgery, and medical staff will adjust the patient's position according to the oral treatment situation. When medical staff and patients are close to the examination lamp, the heat generated by the medical staff and patients can easily come into contact with the lamp cover and cause condensation. This condensation causes water to form on the lamp cover surface, and the condensation refracts the light from the examination lamp, affecting the medical staff's observation of the patient's oral surgery. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that condensation easily forms on the surface of the lampshade when the ambient temperature is low in winter, and to propose an adjustable angle inspection lamp.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable-angle inspection light includes an inspection light body, a lamp cover is installed at one end of the inspection light body, and a sensing mechanism is installed on the side of the lamp cover;

[0007] The sensing mechanism includes an outer lamp housing installed on the side of the lamp cover. One end of the outer lamp housing is connected to an infrared distance sensor. A fan is connected inside the outer lamp housing. The fan is electrically connected to the infrared distance sensor. Multiple air outlets are opened on the inner side of the outer lamp housing. A heating wire is connected inside the outer lamp housing. The heating wire is electrically connected to the fan and is located between the fan and the air outlets.

[0008] Preferably, each of the multiple air outlets is rotatably connected to an air guide block, and the inner side of the outer lamp housing is provided with a conical end, the end of which is located on one side of the fan output end.

[0009] Preferably, the air guide block is a rectangular block with symmetrical grooves on both sides.

[0010] Preferably, two arc-shaped blocks are symmetrically connected on the inner side of the air outlet, and the air outlet is inclined to the surface of the lampshade.

[0011] Preferably, one end of the outer lamp housing is rotatably connected to a ring, and multiple blades are connected inside the ring. A through groove is opened on the inner side of the ring, and the through groove communicates with the air outlet.

[0012] Preferably, a reflective strip is provided on one side of the ring.

[0013] Compared with the prior art, this utility model provides an adjustable-angle inspection light, which has the following beneficial effects:

[0014] 1. This adjustable-angle examination lamp uses an infrared distance sensor to monitor the distance between the patient and medical staff, and promptly controls the operation of the fan and heating wire to quickly raise the temperature of the lamp cover surface, thereby reducing the temperature difference on the lamp cover surface and preventing condensation from forming on the lamp cover surface, which would affect the medical staff's oral treatment of the patient.

[0015] 2. This adjustable-angle examination light, by setting up an air outlet and an air guide block, can accelerate the coverage of hot air on the lamp cover surface, thereby increasing the heating speed of the lamp cover. It also maintains an angle with the lamp cover to prevent hot air from affecting patients and medical staff. In addition, the rotation of the ring serves as a reminder to medical staff, making it convenient for them to adjust the examination light body in a timely manner. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Example 1:

[0025] Reference Figure 1-4 An adjustable-angle examination lamp includes an examination lamp body 1, on which multiple robotic arms are mounted, and adjacent robotic arms are connected by a damping shaft, allowing for easy pulling and stopping. This ensures that the lampshade 2 on the examination lamp body 1 is at a suitable height from the shadowless lamp and the patient. The lower end of the examination lamp body 1 is connected to multiple sets of pulleys, facilitating medical personnel to push the examination lamp body 1 to a suitable position. A lampshade 2 is mounted on one end of the examination lamp body 1, and a sensing mechanism 3 is mounted on the side of the lampshade 2. This mechanism can detect the distance between the patient and the medical personnel and the lampshade 2. If the distance is too close, heating of the lampshade 2 is automatically activated to prevent condensation from forming on the surface of the lampshade 2, which would affect the refracted light produced by the shadowless lamp inside the lampshade 2 and the medical personnel's observation of the patient's oral cavity.

[0026] The sensing mechanism 3 includes an outer lamp housing 301 mounted on the side of the lampshade 2. The outer lamp housing 301 surrounds the lampshade 2, and both ends of the outer lamp housing 301 protrude from the surface of the lampshade 2. An infrared distance sensor 302 is connected to one end of the outer lamp housing 301 to measure the distance between the patient and the lampshade 2 by reflecting infrared light. A fan 303 is connected inside the outer lamp housing 301. The fan 303 is a cooling fan with fan blades and a motor inside. After being powered on, the fan 303 drives the motor to rotate and the fan blades to generate airflow. When the infrared distance sensor 302 detects that the distance to the patient is too close, it can drive the fan 303 and the heating wire to work, thereby generating hot air to appropriately heat the surface of the lampshade 2 and reduce the generation of condensation. The fan 303 is electrically connected to the infrared distance sensor 302. Multiple air outlets 304 are opened on the inner side of the outer lamp housing 301 to evenly distribute the hot air. The heat is applied to the surface of the lampshade 2 and heated. A heating wire 305 is connected inside the outer lamp housing 301. The heating wire 305 is electrically connected to the fan 303 and is located between the fan 303 and the air outlet 304. The distance between the lampshade 2 and the patient is constantly detected by the infrared distance sensor 302. When the distance is not too close, the lampshade 2 and the medical staff work normally. When the medical staff adjusts the examination lamp body 1 and changes the position and angle of the lampshade 2, they inevitably get too close to the lampshade 2. At this time, the infrared distance sensor 302 triggers the fan 303 and the heating wire 305 to work. The generated hot air moves out through the air outlet 304 inside the outer lamp housing 301. At this time, the hot air comes into contact with the lampshade 2 and quickly heats it up, reducing the temperature difference between the surface of the lampshade 2 and the heat on the patient's body. This helps to prevent the heat from condensing on the cooler surface of the lampshade 2, which would affect the refraction effect of the light in the lampshade 2.

[0027] Multiple air outlets 304 are rotatably connected to air guide blocks 306 on their inner sides. The air guide blocks 306 are rectangular blocks with symmetrical grooves on both sides. Since the air outlets 304 are located inside the outer lamp housing 301, they form perpendicular contact with the hot air entering the outer lamp housing 301. At this time, the airflow between the arc-shaped block 308 and the air outlet 304 is constantly different. The air guide blocks 306, with their symmetrical grooves on both sides, can generate different thrusts on the grooves when in contact with the hot air, causing the air guide blocks 306 to oscillate irregularly within the air outlets 304. This reduces the time the hot air covers the surface of the lamp cover 2, accelerating the heating rate of the lamp cover 2. The inner side of the outer lamp housing 301 is provided with a conical end 307. The conical surface of the conical end 307 can guide the hot air, making the fan... The air generated by 303 quickly enters the outer lamp housing 301 and forms a large air pressure. The end of the conical end 307 is located on one side of the output end of the fan 303. Two arc-shaped blocks 308 are symmetrically connected to the inner side of the air outlet 304. This can prevent the air guide block 306 from tilting to one side and making close contact with one side of the air outlet 304, which would cause the air pressure on one side to be continuously greater than that on the other side. This would prevent the air guide block 306 from swinging normally and quickly spreading the hot air to the entire surface of the lamp cover 2. The air outlet 304 is tilted relative to the surface of the lamp cover 2. The tilted air outlet 304 can guide the hot air to directly contact the surface of the lamp cover 2, accelerate the heating rate of the lamp cover 2, and prevent it from spreading outward, thus reducing the impact on patients and medical staff.

[0028] Example 2:

[0029] Reference Figure 5 One end of the outer lamp housing 301 is rotatably connected to a ring 4, and multiple blades 5 are connected inside the ring 4. A through groove 6 is opened on the inner side of the ring 4, which is connected to the air outlet 304. A reflective strip 7 is provided on one side of the ring 4. When the hot air generated by the fan 303 and the heating wire 305 rushes into the outer lamp housing 301, it will push the blades 5 on the ring 4, causing the ring 4 to rotate inside the outer lamp housing 301. At this time, the hot air inside the outer lamp housing 301 can continue to move out from the through groove 6 and contact the surface of the lamp cover 2 through the air outlet 304 on the inner side of the outer lamp housing 301. In addition, the ring 4 can drive the reflective strip 7 to rotate during the rotation, which can attract the attention of medical staff and patients, making it convenient for medical staff to adjust the examination lamp body 1 in a timely manner.

[0030] In this invention, by having medical personnel push the examination cart body to a suitable position and adjust the robotic arm of the examination lamp body 1, the light from the examination lamp body 1 and the shadowless lamp inside the lampshade 2 can completely illuminate the patient's oral cavity. The angle and position of the lampshade 2 will continue to be adjusted during the procedure to facilitate oral treatment. When adjusting the examination lamp body 1 causes the lampshade 2 to get too close to the patient and medical personnel, the infrared distance sensor 302 is triggered and drives the fan 303 and heating wire 305 to work. The generated hot air enters the outer lamp housing 301 with a certain initial velocity, and the hot air quickly passes through both sides of the air guide block 306, causing the air guide block 306 to swing at the air outlet 304. This results in the hot air exiting from the air outlet 304 at different angles, accelerating the speed at which the hot air covers the surface of the lampshade 2 and increasing the heating rate of the lampshade 2 surface. This helps reduce the generation of condensation caused by the temperature difference on the lampshade 2 surface, preventing the condensation on the lampshade 2 surface from refracting light and affecting the oral treatment surgery performed by the medical personnel.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
