Abstract
Description
Technical Field
[0001] This application relates to the field of electroencephalography (EEG) machine technology, and more specifically, to a protective mechanism and an EEG machine. Background Technology
[0002] An electroencephalogram (EEG) machine includes a monitor, keyboard, and main unit, and sometimes a printer. It is mounted on a portable rack that can be moved to various wards. Medical staff can stand and operate the keyboard. The rack has a high center of gravity, and the ward is small and crowded, so the EEG machine is prone to tipping over, resulting in poor safety features. Utility Model Content
[0003] To overcome the above deficiencies, this application provides a protective mechanism and an electroencephalogram (EEG) machine, which aim to improve the problems mentioned in the background art.
[0004] In a first aspect, embodiments of this application provide a protective mechanism, including a frame on which an electroencephalogram (EEG) machine is placed. The lower end of the frame is provided with casters, and both sides of the frame are provided with lifting mechanisms. The lifting mechanisms are provided with rotating mechanisms, and the rotating mechanisms are provided with suction cups. The frame is provided with a negative pressure mechanism that communicates with the suction cups.
[0005] In one specific implementation, the lifting mechanism includes a guide rod and a slide, the guide rod being fixedly connected to the frame and the slide being slidably connected to the guide rod.
[0006] In one specific implementation, the lifting mechanism further includes a lead screw and a motor. The motor is mounted on the frame, the lead screw is rotatably connected to the frame, the lead screw is fixedly connected to the output end of the motor, and the lead screw is threadedly connected to the slide.
[0007] In the above process, the motor drives the lead screw to rotate, which in turn drives the carriage to move up and down along the guide rod, thereby realizing the raising and lowering of the suction cup.
[0008] In one specific implementation, the rotating mechanism includes a rotating frame rotatably connected to the slide, a pin is provided on the rotating frame, a pin hole adapted to the pin is provided on the slide, and the suction cup is fixedly connected to the outer end of the rotating frame.
[0009] In the above process, the rotating frame extends outward to obtain more stable support. When not in use, it can be turned to the lower part of the frame to save floor space. The angle of the rotating frame can be locked by inserting a pin into the carriage to prevent swaying.
[0010] In one specific implementation, the pin hole on the carriage is connected to the negative pressure mechanism.
[0011] In the above process, when the negative pressure mechanism is working, the suction cup contacts the ground and generates suction. The negative pressure is also applied to the pin hole, which pulls the pin up and automatically achieves pin connection. It should be noted that the upper end of the pin hole and the lower end of the pin position are both equipped with top rods to facilitate the movement of the pin under air pressure. In addition, the lower end of the pin is equipped with a vent hole to communicate with the atmosphere so that the pin can be smoothly sucked into the pin hole.
[0012] In one specific implementation, the negative pressure mechanism includes connecting pipes, and two connecting pipes are provided. The two connecting pipes are fixedly connected to the slide and the rotating frame respectively, and the end faces of the two connecting pipes are rotatably connected.
[0013] In the above process, when the rotating frame rotates relative to the slide, the two connecting pipes rotate relative to each other. A sealing ring is provided on the end face of the connecting pipe to ensure sealing during rotation. It should be noted that a spring buckle is provided between the rotating frame and the slide to achieve basic positioning of the rotating frame.
[0014] In one specific implementation, the negative pressure mechanism further includes a telescopic tube and a vacuum pump. The vacuum pump is mounted on the frame, and both ends of the telescopic tube are fixedly connected to the vacuum pump and the corresponding connecting pipe, respectively.
[0015] In the above process, the vacuum pump is connected to the suction cup through the telescopic tube and connecting pipe to generate negative pressure suction. The telescopic tube can adapt to the lifting and lowering movements of the lifting mechanism.
[0016] Secondly, this application also provides an electroencephalogram (EEG) machine, including the aforementioned protective mechanism.
[0017] Compared with the prior art, the beneficial effects of this application are: the suction cup is moved up and down by the lifting mechanism, and the suction cup is rotated out or in from the bottom of the frame by the rotating mechanism, which helps to improve stability when supported and reduce the footprint when pushed, making the frame and the EEG machine on it less likely to be knocked over, thus providing good protection.

Detailed Implementation
[0025] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.
[0026] Please see Figures 1-5 This application provides a protective mechanism, including a frame 10 on which an electroencephalograph (EEG) machine is placed. The frame 10 has casters 20 at its lower end, and lifting mechanisms 30 are provided on both sides of the frame 10. A rotating mechanism 40 is arranged along the lifting mechanism 30, and a suction cup 60 is provided on the rotating mechanism 40. A negative pressure mechanism 50 is provided on the frame 10 and communicates with the suction cup 60. The lifting mechanism 30 moves the suction cup 60 up and down, and the rotating mechanism 40 controls the suction cup 60 to rotate in and out of the lower end of the frame 10. This improves stability during support and reduces the footprint during movement, making the frame 10 and the EEG machine less likely to be knocked over, thus providing good protection.
[0027] Please see Figures 1-5 The lifting mechanism 30 includes a guide rod 31 and a slide 32. The guide rod 31 is fixedly connected to the frame 10, and the slide 32 is slidably connected to the guide rod 31. The lifting mechanism 30 also includes a lead screw 33 and a motor 34. The motor 34 is mounted on the frame 10, the lead screw 33 is rotatably connected to the frame 10, the lead screw 33 is fixedly connected to the output end of the motor 34, and the lead screw 33 is threadedly connected to the slide 32. The motor 34 drives the lead screw 33 to rotate, thereby driving the slide 32 to move up and down along the guide rod 31, realizing the raising and lowering of the suction cup 60.
[0028] Please see Figures 1-5The rotating mechanism 40 includes a rotating frame 41, which is rotatably connected to a slide 32. A pin 42 is mounted on the rotating frame 41, and a pin hole matching the pin 42 is provided on the slide 32. A suction cup 60 is fixedly connected to the outer end of the rotating frame 41. The rotating frame 41 extends outward for more stable support. When not in use, it can be rotated to the lower part of the frame 10 to save floor space. The angle of the rotating frame 41 can be locked by inserting the pin 42 into the slide 32 to prevent wobbling.
[0029] Please see Figures 1-5 The pin hole on the carriage 32 is connected to the negative pressure mechanism 50. When the negative pressure mechanism 50 is working, the suction cup 60 contacts the ground and generates suction. Negative pressure is also applied to the pin hole, which pulls up the lower pin 42 and automatically achieves pin engagement. It should be noted that a top rod is provided at the upper end of the pin hole and the lower end of the pin 42 to facilitate the movement of the pin 42 under air pressure. A vent hole is provided at the lower end of the pin 42 to communicate with the atmosphere so that the pin 42 can be smoothly sucked into the pin hole.
[0030] Please see Figures 1-5 The negative pressure mechanism 50 includes two connecting pipes 51, which are fixedly connected to the slide 32 and the rotating frame 41 respectively. The end faces of the two connecting pipes 51 are rotatably connected. When the rotating frame 41 rotates relative to the slide 32, the two connecting pipes 51 rotate relative to each other. A sealing ring is provided on the end face of the connecting pipe 51 to ensure sealing during rotation. It should be noted that a spring buckle is provided between the rotating frame 41 and the slide 32 to achieve basic positioning of the rotating frame 41.
[0031] Please see Figures 1-5 The negative pressure mechanism 50 also includes a telescopic tube 52 and a vacuum pump 53. The vacuum pump 53 is mounted on the frame 10, and both ends of the telescopic tube 52 are fixedly connected to the vacuum pump 53 and the corresponding connecting pipe 51, respectively. The vacuum pump 53 is connected to the suction cup 60 through the telescopic tube 52 and the connecting pipe 51 to generate negative pressure suction. The telescopic tube 52 can adapt to the lifting and lowering movements of the lifting mechanism 30.
[0032] Please see Figures 1-5 This application also provides an electroencephalogram (EEG) machine, including the aforementioned protective mechanism.
[0033] The working principle of this protective mechanism is as follows: When pushed, the rotating frame 41 turns the suction cup 60 to the lower part of the frame 10 to reduce the footprint. At the same time, the lifting mechanism 30 raises the suction cup 60 to avoid obstructing the push. When it reaches the ward, the rotating frame 41 is turned out by foot. Then, the vacuum pump 53 is connected to the suction cup 60 through the telescopic pipe 52 and the connecting pipe 51 to generate negative pressure suction. The negative pressure sucks up the pin 42 and inserts it into the pin hole on the slide 32, thereby locking the angle of the rotating frame 41. The motor 34 drives the lead screw 33 to rotate, and then... The drive carriage 32 moves downward along the guide rod 31, causing the suction cup 60 to adhere tightly to the ground and maintain suction, thus ensuring that the frame 10 is stably supported on the ground. This guarantees the stable use of the EEG machine and prevents it from being knocked over. In summary, the lifting mechanism 30 moves the suction cup 60 up and down, and the rotating mechanism 40 controls the suction cup 60 to rotate out or in from the bottom of the frame 10. This improves stability during support and reduces the footprint during movement, making the frame 10 and the EEG machine on it less likely to be knocked over, thus providing good protection.
