[0002] In clinical practice, infrared lamps are widely used as medical lamps. They have a significant effect on wound healing after local skin flap transplantation, wound suture and limb replantation. Specifically, the infrared rays emitted by infrared lamps can irradiate the patient's affected area, thereby effectively promoting local blood circulation and improving blood supply.

[0003] In the actual clinical use of infrared heating lamps, various patient conditions will be encountered. In some patients, the affected area is large, requiring the infrared heating lamp to have a larger infrared light irradiation range to cover a larger area of ​​the affected area; while in other patients, the wound area is small and requires a stronger infrared light intensity, requiring the infrared light emitted by the infrared heating lamp to be able to converge on a smaller area and irradiate the affected area to achieve a good auxiliary treatment effect.

[0044] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings, wherein the same components are represented by the same reference numerals.

[0045] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the accompanying drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0046] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0047] See attached Figures 1 to 4 A medical infrared heating lamp comprises a base 10, a bracket 20, a lampshade 30, and an infrared system of the heating lamp; the base 10, the bracket 20, and the lampshade 30 are sequentially connected from bottom to top, and the infrared emitting module of the infrared system of the heating lamp is located in the lampshade 30; the lampshade 30 is provided with two ends, namely, a tail end and an irradiation port; the infrared ray emitted by the infrared emitting module in the lampshade 30 is emitted from the irradiation port. It also comprises an irradiation range regulator 40, which comprises a shading cloth 50, a rope 60, a rope pipe 70, a winch 80, and a position limiter 90.

[0048] The shading cloth 50 is tubular, and its two ends are respectively a fixed port and a movable port. The fixed port of the shading cloth 50 is fixedly connected to the irradiation port of the lampshade 30; the movable port of the shading cloth 50 is fixedly provided with a movable ring 51, which is inserted into the outer periphery of the lampshade 30.

[0049] The rope 60 is wound around the outer periphery of the fixed end of the shading cloth 50, and the wound portion of the rope 60 forms an irradiation range adjustment ring 61. Figure 4 After tightening the two ends of the rope 60, the size of the irradiation range adjustment ring 61 of the rope 60 becomes smaller.

[0050] Two rope pipes 70 are provided in total, and the rope pipes 70 are fixedly provided on the outer wall of the lampshade 30 ; each end of the rope 60 passes through one of the rope pipes 70 separately.

[0051] The hoist 80 is used to reel in or unreel the rope 60 through the two ends of the rope 60. After the hoist 80 reels in the two ends of the rope 60, the irradiation range adjustment ring 61 of the rope 60 is reduced, and then the irradiation range adjustment ring 61 tightens the shade cloth 50 at the irradiation opening of the lampshade 30 to form a new irradiation opening smaller than the irradiation opening of the original lampshade 30. Since the infrared rays of the heating lamp are emitted from the new irradiation opening, and due to the adjustable nature of the new irradiation opening, the irradiation range of the heating lamp becomes adjustable.

[0052] The position limiter 90 is located at the outer periphery of the lampshade 30, and sets the movable ring 51 to have multiple limit positions between the two ends of the lampshade 30; when the position is limited, the position limiter 90 is used to limit the movable ring 51 and the lampshade 30 together. The different limit positions of the movable ring 51 between the two ends of the lampshade 30 also determine the size of the new irradiation opening that the irradiation range adjustment ring 61 can tighten the shading cloth 50 to form.

[0053] To summarize, since the winch 80 can adjust the size of the irradiation range adjustment ring 61 of the rope 60, and the position limiter 90 can adjust the position of the movable ring 51 of the blackout cloth 50, it also determines that the irradiation range adjustment ring 61 can tighten the blackout cloth 50 to form the size of the new irradiation port, thereby achieving the effect of making the irradiation range of the baking lamp adjustable.

[0054] Further, the position limiter 90 includes a guide rod 91, a screw rod 92, a fixing ring 93, and a first motor 94;

[0055] The fixing ring 93 is fixed to the outer circumference of the lamp housing 30 .

[0056] The guide rod 91 and the screw rod 92 are arranged in parallel, and the two ends of the guide rod 91 are fixedly connected to the fixing ring 93 and the outer wall of the lampshade 30 respectively; the screw rod 92 is rotatably connected to the fixing ring 93 and the outer wall of the lampshade 30.

[0057] The guide rod 91 passes through the moving ring 51 ; the screw rod 92 is threadedly connected to the moving ring 51 , and the rotating screw rod 92 can drive the moving ring 51 to approach or move away from the irradiation port of the lampshade 30 .

[0058] The first motor 94 is fixedly connected to the fixing ring 93 , and an output end of the first motor 94 is fixedly connected to one end of the screw rod 92 .

[0059] The rotation of the first motor 94 can drive the screw 92 to rotate, and the rotating screw 92 can drive the moving ring 51 to move closer to or away from the irradiation opening of the lampshade 30, so as to adjust the irradiation range adjustment ring 61 to tighten the shading cloth 50 to form the minimum range of the new irradiation opening.

[0060] Further, the hoist 80 includes a base plate 81, a reel 82, a worm gear 83, a worm 84, and a second motor 85;

[0061] The outer wall of the reel 82 is fixedly connected to the two ends of the rope 60. The reel 82 can be rotated in the forward and reverse directions to reel in or unreel the rope 60.

[0062] The base plate 81 is used to support the reel 82 and the reel 82 is rotatably connected to the base plate 81 .

[0063] The worm wheel 83 is coaxially fixed with the reel 82 ; the worm 84 is meshed with the worm wheel 83 .

[0064] The output end of the second motor 85 is fixed to one end of the worm 84 .

[0065] The second motor 85 can drive the worm 84 to rotate. The worm 84 and the worm wheel 83 form a worm and worm wheel rotation structure. The worm and worm wheel rotation structure drives the reel 82 to rotate, thereby winding or unwinding the rope 60, and finally adjusting the size of the irradiation range adjustment ring 61.

[0066] Furthermore, it also includes a controller, a first contact sensor 101, a second contact sensor 102, and a second spring 104; in addition, the second motor 85 is a servo motor.

[0067] A signal input port of a controller (not shown) is connected to a signal output end of the first contact sensor 101 and a signal output end of the second contact sensor 102 . The controller is used to receive signals from the first contact sensor 101 and the second contact sensor 102 .

[0068] The controller is electrically connected to the second motor 85 , and the controller is used to control the rotation of the second motor 85 .

[0069] The base plate 81 of the hoist 80 is slidably connected to the outer wall of the lampshade 30 ; a second spring 104 is fixedly provided on one side of the sliding direction of the hoist 80 ; two ends of the second spring 104 are fixedly connected to the base plate 81 and the lampshade 30 .

[0070] The first contact sensor 101 and the second contact sensor 102 are arranged on both sides of the sliding direction of the hoist 80 , and the detection ends of the first contact sensor 101 and the second contact sensor 102 point to the substrate 81 .

[0071] In the process of reducing the irradiation range, the first motor 94 of the start position limiter 90 rotates forward and drives the moving ring 51 to move toward the irradiation port close to the lampshade 30, and part of the shading cloth 50 is in a relaxed state at the irradiation port of the lampshade 30, and then the irradiation range adjustment ring 61 is also in a relaxed state along with the shading cloth 50, and then the second spring 104 pulls the substrate 81 and the substrate 81 squeezes the detection end of the second contact sensor 102, and then after receiving the signal, the controller controls the winch 80 to reel in the rope 60, and the irradiation range adjustment ring 61 gradually becomes smaller and continues to reel in, controlling the winch 80 to overcome the pulling force of the second spring 104, and then controlling the winch 80 to disengage from the detection end of the second contact sensor 102.

[0072] In the process of increasing the irradiation range (in the process of increasing the new irradiation opening that has been reduced above), the first motor 94 of the start position limiter 90 is reversed and drives the movable ring 51 to move in the direction of the irradiation opening away from the lampshade 30, and part of the shading cloth 50 is in a tensioned state at the irradiation opening of the lampshade 30. The tensioned shading cloth 50 tends to expand the irradiation range adjustment ring 61, and the expanded irradiation range adjustment ring 61 overcomes the elastic force of the second spring 104, and the base plate 81 of the winch 80 contacts the first contact sensor 101; after that, after receiving the signal, the controller controls the winch 80 to unwind the rope 60 until the winch 80 is controlled not to contact the first contact sensor 101, thereby completing the goal of increasing the irradiation range.

[0073] Furthermore, the rope duct 70 has two ends; the first ends of the two rope ducts 70 are both adjacent to the illumination port of the lampshade 30 , and the first ends of the two rope ducts 70 are 180 degrees about the central circumference array of the illumination port of the lampshade 30 .

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
