为了实现支杆5的上下运动，所述套筒3上设有与支杆5相互配合的通槽27，通槽27的长度要短于活塞4长度，通过设置通槽27实现支杆5的上下运动不会与套筒3产生干涉，设置的活塞4的长度长于通槽27满足了无论活塞4怎么运动，都不会造成通槽27与压力箱2产生连通。In order to realize the up and down movement of the pole 5, the sleeve 3 is provided with a through groove 27 cooperating with the pole 5, the length of the through groove 27 is shorter than the length of the piston 4, and the movement of the pole 5 is realized by setting the through groove 27. The up and down movement will not interfere with the sleeve 3, and the length of the set piston 4 is longer than that of the through groove 27 so that no matter how the piston 4 moves, the through groove 27 will not communicate with the pressure tank 2.
为了实现压力箱2的压力稳定，所述每个压力箱2上均设有一个气泵28，通过设置气泵28来保证压力箱2内的压力始终保持稳定状态，从而满足当弧形刮片6触及到非同一水平面上的皮肤从而造成压力箱2内的气压变化时，气泵28能够自动补压。In order to stabilize the pressure of the pressure tank 2, each pressure tank 2 is provided with an air pump 28, and the air pump 28 is provided to ensure that the pressure in the pressure tank 2 is always in a stable state, so as to meet the requirements when the arc scraper 6 touches When the air pressure in the pressure tank 2 changes due to the skin on a different level, the air pump 28 can automatically replenish the pressure.
本发明的具体工作过程是：本装置在初始状态时，最有两侧的弧形刮片6同时处于中间位置，并实现两侧的弧形刮片6的其实位置唯一同一条直线上，此时两个连杆7的下端向中心收缩，拉簧8处于非拉伸状态。The specific working process of the present invention is: when the device is in the initial state, the arc-shaped scrapers 6 on both sides are in the middle position at the same time, and the actual positions of the arc-shaped scrapers 6 on both sides are only on the same straight line. When the lower ends of the two connecting rods 7 contract toward the center, the extension spring 8 is in a non-tensioned state.
当使用本装置时，首先判断患者属于哪种皮肤病，根据不同的皮肤病设定不同的压力值，设置不同的压力值满足不同患者，实现不同的清刮深度，在气泵28的作用下实现压力箱2内的压力增大，当压力箱2内的压力增大后悔推动活塞4在套筒3内向下运动，而在这个运动过程中，活塞4的向下运动带动支杆5沿着通槽27向下运动，而支杆5的向下运动会使的支杆5一端固定的弧形刮片6向下运动，弧形刮片6向下运动会使得弧形刮片6的下端接触皮肤，在弧形刮片6接触皮肤时会带动装置整体向上运动，而此时用手向下按压框架17，框架17受力向下运动，框架17的向下运动会带动支腿20向下运动，而此运动过程会使得支腿20向下挤压压簧22，并使得压簧22收缩，并在压簧22收缩的过程中实现加压其下部的固定的橡胶垫21使得橡胶垫21与皮肤紧密贴合，而在向下挤压框架17的过程中，由于与皮肤相接触的弧形刮片6受到来自皮肤的阻力，因此在这个阻力的作用下会带动弧形刮片6向上运动，从而克服压力箱2所提供的压力，而在这个压紧皮肤克服压力箱2内的压力的过程中，会实现弧形刮片6带动支杆5向上运动，而支杆5的向上运动会带动活塞4在套筒3内向上运动，而活塞4的向上运动，会使得活塞4、套筒3、与压力箱2构成一个密闭腔体内的压力增大，而这个增大过程会使得向下压紧皮肤的力也增大，从而实现弧形刮片6切入到皮肤内的深度变化，从和人满足对不同患者清刮不同深度皮肤病变区域的要求。When using this device, first determine which skin disease the patient belongs to, set different pressure values according to different skin diseases, set different pressure values to meet different patients, and realize different scraping depths, which are realized under the action of the air pump 28 The pressure in the pressure box 2 increases, when the pressure in the pressure box 2 increases, the piston 4 moves downward in the sleeve 3, and during this movement, the downward movement of the piston 4 drives the strut 5 along the passage. The groove 27 moves downward, and the downward movement of the pole 5 will cause the arc-shaped scraper 6 fixed at one end of the pole 5 to move downward, and the downward movement of the arc-shaped scraper 6 will make the lower end of the arc-shaped scraper 6 contact the skin. When the curved scraper 6 touches the skin, it will drive the whole device to move upwards. At this time, the frame 17 is pressed down by hand, and the frame 17 is forced to move downward. The downward movement of the frame 17 will drive the supporting legs 20 to move downward, and This movement process will make the leg 20 press the compression spring 22 downward, and the compression spring 22 will contract, and in the process of compression of the compression spring 22, the fixed rubber pad 21 at the bottom of the compression spring will be pressed so that the rubber pad 21 is close to the skin In the process of pressing the frame 17 downward, since the arc-shaped scraper 6 in contact with the skin is subjected to resistance from the skin, the arc-shaped scraper 6 will be driven to move upward under the action of this resistance, thereby Overcome the pressure provided by the pressure box 2, and in the process of pressing the skin to overcome the pressure in the pressure box 2, the arc-shaped scraper 6 will drive the strut 5 to move upward, and the upward movement of the strut 5 will drive the piston 4 Moving upward in the sleeve 3, and the upward movement of the piston 4 will increase the pressure in a closed cavity formed by the piston 4, the sleeve 3, and the pressure tank 2, and this increasing process will cause the skin to be pressed downward The force is also increased, thereby realizing the depth variation of the arc-shaped scraper 6 cutting into the skin, so as to meet the requirements of different patients for clearing and scraping skin lesion areas with different depths.
当切入皮肤的弧形刮片6达到预先设定的深度后，此时同时打开步进电机12的驱动电机26，而这个两个电机的转速要求是，驱动电机26的转速要远远大于步进电机12的转速，首先步进电机12转动后，会实现步进电机12带动中心轴23的缓慢转动，而中心轴23的转动会带动第一齿轮11的转动，第一齿轮的11的转动会带动其下方的两个第二齿轮13同向转动，两个第二齿轮13的转动有会带动其上固定的螺杆14转动，由于两侧的两个螺杆14的螺旋方向相反，在各自螺母15的配合下实现在两个螺杆14在同向转动的过程中，螺杆14向外侧缓慢推动支撑杆1向外侧移动，而这个过程中，由于螺母15是固定不动的因此，两个螺母15的距离是保持不动的，因此两侧的螺杆14在与其相配合的螺母15的作用下实现同时向两侧推动支撑杆1，实现两个螺母15距离不变的同时使得两侧的两个支撑杆1距离缓慢拉大。After the arc scraper 6 that cuts into skin reaches preset depth, open the driving motor 26 of stepping motor 12 simultaneously at this moment, and the rotating speed requirement of these two motors is, the rotating speed of driving motor 26 will be far greater than stepping motor 26. The rotation speed of the stepping motor 12, firstly after the stepping motor 12 rotates, the stepping motor 12 will drive the slow rotation of the central shaft 23, and the rotation of the central shaft 23 will drive the rotation of the first gear 11, and the rotation of the first gear 11 It will drive the two second gears 13 below it to rotate in the same direction, and the rotation of the two second gears 13 will drive the screw 14 fixed on it to rotate. Since the screw directions of the two screw 14 on both sides are opposite, in the respective nuts Under the cooperation of 15, when the two screw rods 14 are rotating in the same direction, the screw rod 14 slowly pushes the support rod 1 to move outward. In this process, because the nut 15 is fixed, the two nuts 15 The distance between them remains unchanged, so the screw rods 14 on both sides can simultaneously push the support rod 1 to both sides under the action of the nuts 15 matched with it, so that the distance between the two nuts 15 remains unchanged and the two sides on both sides The distance between the support rod 1 is slowly enlarged.
在支撑杆1向两侧运动的过程中会实现支撑杆1两端的第一滑块18在与其对应的第一滑槽19内向外侧滑动，而这个运动过程则会实现每个支撑杆1上所固定的压力箱2向外侧移动，从而带动压力箱2上所固定的套筒3、活塞4以及弧形刮片6向外侧移动，从而实现对病变区域皮肤的清刮。During the movement of the support rod 1 to both sides, the first sliders 18 at both ends of the support rod 1 will slide outwards in the corresponding first chute 19, and this movement process will realize all the support rods 1 on each support rod 1. The fixed pressure box 2 moves to the outside, thereby driving the sleeve 3, the piston 4 and the arc-shaped scraper 6 fixed on the pressure box 2 to move to the outside, thereby realizing the scraping of the skin of the lesion area.
在步进电机12驱动第一齿轮11转动的同时，转动轴9上的驱动电机26也会同时带动驱动轴9转动，驱动轴9的转动会带动其上固定的转杆10转动，在这个连接过程中，要求驱动轴9安装在转杆10的中心位置，并保证转杆10的两端为圆弧面，随着驱动轴9的转动，会带动转杆10转动，转杆10的转动会实现转杆10的两端同时接触到两侧挡板7，并在驱动电机26的带动下实现转杆10推动两侧的两个挡板7同时同速向两侧运动，在此过程中，由于转杆10与挡板7的接触位置关于转杆10中心点中心对称的因此，两个接触点在推动挡板7的位置受力不一样，会出现不稳的现象，因此在两个挡板7之间设有伸缩管16，从而实现两个挡板7在接触受力点不同的情况下依旧能够实现平稳的向两侧运动，并且由于本装置时用于皮肤清刮的因此，在清刮皮肤时不需要很大的力，所以接触点的不同并不能影响本装置的运行，随着驱动电机16的持续转动，两侧的两个挡板7会向两侧运动，这个运动过程中，会使得固定在两个挡板7之间的拉簧8受到拉伸力并处于拉伸状态，并使得拉簧8具有反弹的趋势和动能，两个挡板7之间的伸缩管16也会实现伸长，随着转杆10的转动会实现两侧的挡板7向两侧运动，挡板7的运动会带动其上固定的螺母15向两侧运动，螺母15的运动会带动螺杆14向两侧运动，螺杆14的运动会带动其上固定的第二齿轮13在第一齿轮11上滑动，在这个滑动过程中并不影响第一齿轮11与第二齿轮13的啮合。When the stepping motor 12 drives the first gear 11 to rotate, the driving motor 26 on the rotating shaft 9 will also drive the driving shaft 9 to rotate at the same time, and the rotation of the driving shaft 9 will drive the rotating rod 10 fixed on it to rotate. In the process, the drive shaft 9 is required to be installed at the center of the rotating rod 10, and the two ends of the rotating rod 10 are guaranteed to be arc-shaped. With the rotation of the driving shaft 9, the rotating rod 10 will be driven to rotate, and the rotation of the rotating rod 10 will be Realize that the two ends of the rotating rod 10 contact the baffles 7 on both sides at the same time, and realize that the rotating rod 10 pushes the two baffles 7 on both sides to move to both sides at the same speed under the drive of the drive motor 26. During this process, Since the contact position between the rotating rod 10 and the baffle plate 7 is symmetrical about the center point of the rotating rod 10, the two contact points are subjected to different forces at the position where the baffle plate 7 is pushed, and instability will occur. A telescopic tube 16 is provided between the plates 7, so that the two baffles 7 can still move smoothly to both sides under the condition of different contact force points, and because this device is used for skin cleaning and scraping, it can It does not require a lot of force when scraping the skin, so the difference in contact points does not affect the operation of the device. With the continuous rotation of the drive motor 16, the two baffles 7 on both sides will move to both sides. This movement process In the process, the extension spring 8 fixed between the two baffles 7 will be subjected to tension and be in a stretched state, and the extension spring 8 will have a rebounding tendency and kinetic energy, and the telescopic tube 16 between the two baffles 7 Also can realize elongation, along with the rotation of rotating rod 10 can realize that the baffle plate 7 on both sides moves to both sides, and the motion of baffle plate 7 can drive the nut 15 fixed on it to move to both sides, and the motion of nut 15 can drive screw rod 14 Moving to both sides, the movement of the screw 14 will drive the second gear 13 fixed on it to slide on the first gear 11 , and the meshing between the first gear 11 and the second gear 13 will not be affected during this sliding process.
当转杆10转动到水平位置时，两侧的两个挡板7移动到最外侧，随着转杆10的持续转动，在拉簧8的作用下会使得两个挡板7向中间靠拢，在这个向中间靠拢的过程中，挡板7带动其上固定的螺母15带动螺杆14向中间移动，而这个移动过程中，螺杆14上固定的第二齿轮13在第一齿轮11上滑动，并向中间靠拢，在这个收缩的运动过程中，两个支撑杆1向中间运动并带动其上固定的压力箱2及弧形刮片6向中间靠拢，而在这个向中间靠拢的过程中，弧形刮片6的刃部朝前，因此这个过程不会造成对患者皮肤的二次伤害，随着转杆10的转动，当转杆10脱离挡板7的时候本装置回位到初始位置，在在这个过程中伸缩管16不仅起到稳定两个挡板7的左右还能有效的实现限位效果，保证第二齿轮13在于第一齿轮11啮合的过程中不会相互脱离，并保证在两个挡板7不会向中间靠拢的太过紧密。When the rotating rod 10 is rotated to a horizontal position, the two baffles 7 on both sides move to the outermost side, and as the rotating rod 10 continues to rotate, the two baffles 7 will move closer to the middle under the action of the extension spring 8, In this process of getting closer to the middle, the baffle plate 7 drives the nut 15 fixed on it to drive the screw rod 14 to move to the middle, and during this movement, the second gear 13 fixed on the screw rod 14 slides on the first gear 11, and Move closer to the middle. During the shrinking movement, the two support rods 1 move toward the middle and drive the fixed pressure box 2 and the arc-shaped scraper 6 to move closer to the middle. In the process of moving closer to the middle, the arc The blade of the shaped scraper 6 faces forward, so this process will not cause secondary damage to the patient's skin. With the rotation of the rotating rod 10, when the rotating rod 10 breaks away from the baffle plate 7, the device returns to its original position. In this process, the telescopic tube 16 not only stabilizes the left and right of the two baffles 7 but also effectively realizes the position-limiting effect, ensuring that the second gear 13 will not disengage from each other during the meshing process of the first gear 11, and ensure that Two baffle plates 7 will not be too close to the middle.
完成一侧的皮肤清刮后，转动本装置，使得两侧的弧形刮片6刮取对应侧的皮肤，从而实现对整个病变区与的清刮。After the skin scraping on one side is completed, the device is rotated so that the arc-shaped scraping blades 6 on both sides scrape the skin on the corresponding side, thereby realizing the scraping of the entire lesion area.
本装置对比传统的皮肤清刮器有以下好处：This device has the following advantages over traditional skin scrapers:
1、本装置通过一个气泵28为压力箱2提供预设的定好的压力值，使得本装置在清刮皮肤之前首先在气压力的作用下向下运动活塞4，并使得活塞4上连着的弧形刮片6与皮肤相接处，当弧形刮片6接触到皮肤后会，皮肤会对弧形刮片6提供一个反作用力，而这个反作用力会使得首先接触到发皮肤的弧形刮片6停止向下运动，而使的那些还没有接触到皮肤的弧形刮片6接着向下移动，直至所有的弧形刮片6全部接触到皮肤，而这时候由于各个套筒3全部都是连通的因此，每个套筒3内的压力也是一样的，因此弧形刮片6接触到皮肤的力也是一定的，这样既能保证本装置能够更加完美的贴合不平整位置的皮肤同时又能保证皮肤在清刮的过程中受力均匀，有效的避免了清刮器以及人工清刮所造成的二次伤害。1. The device provides a preset pressure value for the pressure box 2 through an air pump 28, so that the device first moves the piston 4 downward under the action of air pressure before scraping the skin, and makes the piston 4 connected Where the curved scraper 6 meets the skin, when the curved scraper 6 touches the skin, the skin will provide a reaction force to the curved scraper 6, and this reaction will make the arc that first touches the skin The scraper blades 6 stop moving downwards, and those arc-shaped scraper blades 6 that have not touched the skin move downwards until all the arc-shaped scraper blades 6 touch the skin. They are all connected. Therefore, the pressure in each sleeve 3 is the same, so the force of the arc-shaped scraper 6 touching the skin is also certain, which can ensure that the device can fit the uneven skin more perfectly. At the same time, it can ensure that the skin is evenly stressed during the scraping process, effectively avoiding the secondary damage caused by the scraper and manual scraping.
2、本装置在请过的过程中采用了双向运动的方式，也就是在起始位置时，首先使得左右两侧的弧形刮板的刃部处于同一条水平面上，而分开两部分向左右两侧同时进行清刮，而同侧的病变区域清刮只进行了一半的区域，但是清关大面积的时间趋势一样的，这种清刮方式有效的解决了在皮肤清刮的过程中，皮肤由于受到刮刀的剐蹭而出现的皮肤松动，而这个松动效果会实现在清刮皮肤的时候造成皮肤的褶皱，而这个褶皱是极易造成刮刀对皮肤的二次伤害，传统解决这样的问题时是要一直手进行按压保证皮肤不会起皱聪哥实现清刮，但这种方式并不省力，在本装置中，采用双向同时清刮，两侧的弧形刮片6即使清刮工具同时又为对侧的清刮提供了有效的按压效果实现清刮的过程中不会出现皮肤松动，从而避免了对皮肤的二次伤害。2. This device adopts a two-way movement method during the process of passing, that is, at the initial position, firstly make the blades of the curved scrapers on the left and right sides be on the same horizontal plane, and separate the two parts to the left and right Both sides are scraped at the same time, while only half of the lesion area on the same side is scraped, but the time trend of clearing a large area is the same. This scraping method effectively solves the problem of skin damage during the scraping process The skin is loosened due to scraping by the scraper, and this loosening effect will cause skin folds when the skin is scraped, and this fold is very likely to cause secondary damage to the skin by the scraper. The traditional solution to this problem is You need to keep pressing with your hands to ensure that the skin will not wrinkle, but this method is not labor-saving. In this device, two-way simultaneous scraping is used, and the curved scrapers 6 on both sides can be scraped at the same time. It provides an effective pressing effect for the scraping on the opposite side, so that the skin will not loosen during the scraping process, thereby avoiding secondary damage to the skin.
3、传统的皮肤清刮一般是采用刮刀在皮肤表面进行一个往复运动同时实现向前推进，这样做的好处就是往复的缓慢前进是对皮肤进行表面的磨削，通过缓慢的磨削使得皮肤上的病变区域松动，这样做的好处是避免直接进行清刮对皮肤造成损伤，现有的皮肤清刮器一般都是采用一次性清刮，这样的清刮方式，是使用刃部直接刮动，其清刮过程对患者的皮肤伤害是巨大的，同时也不能保证皮肤病变区与能够清刮的彻底，而本装置模拟人工清刮，通过往复的缓慢推进实现清刮与磨削共同进行实现皮肤清刮过程中更加的人性化。3. The traditional skin scraping generally uses a scraper to perform a reciprocating movement on the skin surface while advancing forward. The advantage of this is that the slow reciprocating movement is the surface grinding of the skin, and the slow grinding makes the skin smooth. The lesion area is loosened. The advantage of this is to avoid the skin damage caused by direct scraping. The existing skin scrapers generally use one-time scraping. This kind of scraping method is to use the blade to scrape directly. The scraping process does great damage to the patient's skin, and at the same time, it cannot guarantee that the skin lesion area can be completely scraped. However, this device simulates manual scraping, and realizes scraping and grinding together through reciprocating slow advancement to achieve skin healing. It is more humanized in the scraping process.
4、本装置通过一个在持续转动的步进电机12带动转动轴9转动，转动轴9缓慢转动实现第一齿轮11带动两个与其相啮合的第二齿轮13转动，第二齿轮13的转动带动螺杆14在螺母15的配合下持续向两侧缓慢推动支撑杆1，并在实现支撑杆1向两侧不停运动的过程中实现螺母14之间的距离保持不变，此过程就是本装置的缓慢向前推移的过程，在转杆10的转动推动挡板7向两侧运动，同时经螺母15带动螺杆14快速的向两侧推移并在拉簧8的作用下实现复位，随着转动的持续会实现挡板7的分开与聚合，此过程中为往复运动过程，本装置通过缓慢推进和多次往复运动实现清刮更加彻底，也使得清刮更加的温和，人性化。4. This device drives the rotating shaft 9 to rotate through a continuously rotating stepping motor 12, and the rotating shaft 9 slowly rotates to realize that the first gear 11 drives two second gears 13 meshing with it to rotate, and the rotation of the second gear 13 drives The screw rod 14 continues to slowly push the support rod 1 to both sides under the cooperation of the nut 15, and realizes that the distance between the nuts 14 remains unchanged during the process of realizing the non-stop movement of the support rod 1 to both sides. This process is the key point of the device. In the process of slowly moving forward, the rotation of the rotating rod 10 pushes the baffle plate 7 to move to both sides, and at the same time, the nut 15 drives the screw rod 14 to quickly move to both sides and reset under the action of the extension spring 8. The separation and aggregation of the baffle plate 7 will be realized continuously. This process is a reciprocating movement process. The device realizes more thorough scraping through slow advancement and multiple reciprocating movements, which also makes the scraping more gentle and humanized.
本发明构思新颖，结构巧妙，实用性强，通过压力箱实现各个弧形刮片接触皮肤的力都是等大，并通过弧形刮片同左右同时进行清刮保证了在清刮皮肤的过程中更加的舒适以及人性化，同时采用往复缓慢推进的方式实现皮肤清刮的更加彻底。The present invention is novel in conception, ingenious in structure, and strong in practicability. The pressure box realizes that the force of each arc-shaped scraper in contact with the skin is equal, and the arc-shaped scraper is used to clean the left and right sides at the same time to ensure the process of skin clearing. It is more comfortable and humanized, and at the same time, it adopts the reciprocating and slow advancing method to achieve a more thorough skin scraping.
