Technical Field

[0001] The present application relates to the technical field of medical physiotherapy equipment, and in particular to an automatic scraping device. Background Art

[0002] Gua Sha is a traditional Chinese medicine therapy based on the theory of meridians and acupoints. Using a specially designed scraping tool, a medium is applied repeatedly to the body surface, causing the skin to develop red, millet-like or dark red hemorrhagic spots, thereby promoting blood circulation and clearing the blood. Its core principle is to dredge the meridians and regulate the balance of qi and blood. It is widely used clinically and is simple and economical.

In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application. Refer to the attached Figures 1 to 2 The embodiment of the present application provides an automatic scraping device, including a bracket 100, a moving component 200, a lifting component 300 and an adaptive scraping component 400, wherein the bracket 100 spans the patient's back and is used to provide an installation base for the moving component 200, the lifting component 300 and the adaptive scraping device. The moving component 200 is installed on the bracket 100 and moves on the bracket 100 along the length direction of the back. The lifting component 300 is fixed to the bottom of the moving component 200 and moves synchronously with the moving component 200 in the same direction. The adaptive scraping component is arranged at the bottom of the lifting component 300, and is driven by the downward movement of the lifting component 300 to contact the patient's back and cooperate with the movement of the moving component 200 to enable the adaptive scraping component to perform a scraping operation along the length direction of the patient's back.

[0020] Specifically: like Figures 1 to 2 As shown, the bracket 100 includes a set of parallel guide rails 101 and counterweight legs 102 for placing the guide rails 101. The counterweight legs 102 are integrally formed at the bottom of the guide rails 101. The two guide rails 101 are located on both sides of the bed along the length direction of the bed. A rail groove is provided along the length direction of the guide rails 101. The moving component 200 is installed in the rail groove and moves along the length direction of the guide rails 101.

[0021] In the above embodiment, by using the counterweight support legs 102 to set up the guide rail 101, the moving component 200, the lifting component 300 and the adaptive scraping component 400 can be suspended above the patient's back. At the same time, the guide rail 101 is used as a reference for the movement guide to ensure that the moving component 200 can carry the lifting component 300 and the adaptive scraping component 400 to move along the length direction of the patient's back, thereby accurately completing the scraping operation on the entire back plane.

[0022] Continue as Figures 1 to 3As shown, the moving assembly 200 includes a screw shaft 201, a motor 202 and a moving frame 203, wherein the screw shaft 201 is rotatably set in the rail groove, the two ends of the screw shaft 201 are optical axes, and the two ends of the screw shaft 201 form a rotational matching relationship with the guide rail 101 through bearings, wherein one end of the screw shaft 201 extends outside the guide rail 101, and is connected to the output end of the motor 202 through a coupling, and the motor 202 is used to drive the screw shaft 201 to rotate, and the moving frame 203 spans between the two guide rails 101, and ear holes are provided at both ends of the moving frame 203, which form a threaded connection with the screw shaft 201. At the same time, to ensure that the screw shafts 201 on both sides rotate synchronously, the motor 202 is controlled by the same control switch.

[0023] In the above embodiment, the motor 202 drives the screw shaft 201 to rotate, and the threaded fitting relationship between the movable frame 203 and the screw shaft 201 is utilized to realize the movement of the movable frame 203 along the length direction of the guide rail 101, that is, the movable component 200 carries the lifting component 300 and the adaptive scraping component 400 to move along the length direction of the patient's back.

[0024] Others, such as Figure 1 and Figure 2 As shown, the lifting assembly 300 is an automatic telescopic rod, which includes at least two automatic telescopic rods and is symmetrically installed on the bottom of the moving frame 203 by bolts.

[0025] In the above embodiment, the automatic telescopic rod is simple in structure and low in cost compared with the air cylinder and the oil cylinder, and can realize the lifting and lowering movement of the adaptive scraping assembly 400.

[0026] At the same time in this embodiment, Figure 1 、 Figure 2 and Figure 4 As shown, the adaptive scraping assembly 400 includes a platform 401, a plurality of elastic members 402, and a scraping plate 404. The platform 401 is fixedly mounted to the output end of the lifting assembly 300 via a flange, the elastic members 402 are mounted on the bottom of the platform 401 and arranged along the width of the back, and the elastic members 402 have the function of longitudinal telescopic adjustment. The scraping plate 404 is rotatably mounted on the bottom of the elastic members 402. When the scraping plates 404 are arranged along the width of the back, they can form a combined "scraping plate" that is the same length as the width of the patient, so that the entire back can be scraped in one go.

[0027] In the above embodiment, by arranging several groups of elastic members 402 along the width direction of the patient's back and rotatably installing the scraping plates 404 at the bottom, and utilizing the telescopic adjustment function of the elastic members 402, the scraping plates 404 at different positions can be fitted with the back, so that the scraping plates 404 can form a combined "scraping plate" that is consistent with the width length of the patient, so that the entire back can be scraped at one time.

[0028] In a preferred embodiment, in order to realize forming a combined "scraping board" covering the width direction of the patient's back, such as Figure 1 and Figure 2 As shown, the elastic members 402 are divided into two groups. The two groups of elastic members 402 are arranged in parallel along the width direction of the back, and each group includes multiple elastic members 402 arranged at intervals. The two groups of elastic members 402 are staggered front to back, and there is no gap in the projections of the two groups of elastic members 402 on the transverse plane, where the transverse plane is a cross-section along the width direction of the back and perpendicular to the back.

[0029] In the above embodiment, the advantage of using two groups of elastic members 402 staggered front and back instead of one group of elastic members 402 is that if one group of elastic members 402 is used, the scraping plates 404 may squeeze or interfere with each other during rotation, and the distribution arrangement is not flexible enough. However, using two groups of elastic members 402 staggered front and back allows gaps between adjacent scraping plates 404 to not interfere with each other, and the gaps between adjacent scraping plates 404 are filled by the scraping plates 404 at the rear, and a complete combined "scraping plate" can still be formed on the horizontal surface, and the assembly can successfully complete the scraping operation on the entire back at one time.

[0030] In a preferred embodiment, Figure 4 As shown, the elastic member 402 includes a sleeve 4021, a movable rod 4022 and a spring 4023. A positioning hole is provided at the bottom of the platform 401. The sleeve 4021 is inserted into the positioning hole with interference fit. The movable rod 4022 is inserted into the sleeve 4021. The mouth of the sleeve 4021 is designed to be closed. The movable rod 4022 is a T-shaped rod structure to prevent it from falling out of the sleeve 4021. A base 403 is provided at one end of the bottom of the movable rod 4022 that is exposed from the sleeve 4021. The spring 4023 is sleeved on the movable rod 4022 and abuts between the base 403 and the bottom of the sleeve 4021.

[0031] In this embodiment, when the lifting assembly 300 moves downward, the elastic member 402 and the scraping plate 404 are driven to move downward. Since the scraping plate 404 and the elastic member 402 are in a rotationally connected relationship, the scraping plate 404 will rotate due to the certain curvature of the back, which is conducive to the scraping plate 404 fitting closely to the patient's back. Since the patient's back has a certain curvature, the scraping plate 404 contacts the back in a certain order. Therefore, by providing the elastic member 402 to be retractable, all the scraping plates 404 can fit closely to the back. Figure 5 shown.

[0032] Of course, it is understandable that the range of variation of the back curvature is small, so when all the scraping plates 404 are in contact with the back, the difference between the maximum pressure and the minimum pressure on the elastic member 402 is very small, and it can be approximated that the pressure on all elastic members 402 is the same.

[0033] In a preferred embodiment, Figure 4 As shown, a pressure membrane sensor 500 is provided at the bottom of the sleeve 4021, and the pressure membrane sensor 500 is in contact with the spring 4023. A display 600 is provided on the top of the platform 401, and the pressure membrane sensor 500 is connected to the display 600. The display 600 has multiple display areas for displaying the pressure value of each pressure membrane sensor 500.

[0034] In this embodiment, when the lifting assembly 300 moves downward, the scraping plate 404 contacts the back and squeezes the movable rod 4022 into the sleeve 4021. The spring 4023 is compressed and generates pressure on the pressure membrane sensor 500. The pressure of the scraping plate 404 on the back can be displayed through the display 600, thereby controlling the descending distance of the lifting assembly 300.

[0035] In the above, the pressure film sensor 500 may be a WIKA BME-76 ceramic thick film sensor suitable for micro-range detection, and the display 600 may be an Advantech IDS-3300 display, which supports multiple independent data windows and can display pressure values ​​simultaneously.

[0036] In the above embodiment, if Figure 4 As shown, a mounting groove is provided at the bottom of the base 403, and the scraping plate 404 is set in the mounting groove through the rotation speed of the pivot. The rotation direction of the scraping plate 404 is parallel to the length direction of the back, and a torsion spring is provided on the pivot to restore the scraping plate 404 to a horizontal position.

[0037] It can be imagined that in this embodiment, the scraping plate 404 and the base 403 are in a rotational fit relationship. Therefore, when the scraping plate 404 contacts the curved back, the scraping plate 404 will deflect under the pressure to form an inclination that fits the back, thereby forming an arc-shaped combined "scraping plate". Figure 5 shown.

[0038] It can be seen that Figure 5 As shown, an automatic scraper provided by an embodiment of the present application, when in use, is driven by the lifting component 300 to drive the adaptive scraping component 400 to move downward, so that the scraping plate 404 fits with the back 700 to form an arc-shaped combined "scraping plate" structure, and then the moving component 200 drives the lifting component 300 and the adaptive component 400 to move along the guide rail 101, thereby completing the scraping therapy of the entire back plane at one time.

[0039] In summary, an automatic scraper provided in an embodiment of the present application includes a bracket 100, a lifting assembly 300 and an adaptive scraping assembly 400, the bracket 100 is provided with a moving assembly 200 that moves along the length direction of the back; the lifting assembly 300 is fixed to the bottom of the moving assembly 200; the adaptive scraping assembly 400 includes a platform 401 arranged at the bottom of the lifting assembly 300, a plurality of longitudinally retractable elastic members 402 arranged at the bottom of the platform 401, and a scraping plate 404 rotatably arranged at the bottom of the elastic member 402, the elastic member 402 is arranged along the width direction of the back, and the rotation axis of the scraping plate 404 is parallel to the length direction of the back. In this technical solution, several scraping boards are set along the width direction of the back so that the scraping boards can occupy the entire width of the back. At the same time, the adaptive scraping board is driven downward by the lifting component, and the scraping board is adaptively fitted with the curved surface in the width direction of the patient's back by the expansion and contraction of the elastic part. Therefore, when the moving component drives the adaptive scraping component to move along the length direction of the back, the scraping operation of the entire back plane can be completed at one time, effectively reducing the scraping time and improving the scraping efficiency. In the entire scraping process, the movement of the scraping board is realized by the lifting component and the moving component, which can effectively control the scraping force to remain basically consistent.

[0040] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application.
