Description

Human body back automatic control scraping instrument

technical field

The invention relates to a medical device, in particular to an automatic control scraping device for the back of a human body.

Background technique

Gua Sha is a method commonly used in traditional Chinese medicine to treat diseases. It occupies a very important position in traditional Chinese culture. Since Gua Sha does not require high professional skills like acupuncture or cupping, it can be used by ordinary people. The traditional scraping device is a flat body slightly in the shape of a round block, and most of them are made of raw materials such as horns. Clinically, when performing scraping treatment on patients, since the scraping device is only a small piece, the operator needs to hold the scraping device firmly to perform scraping, which is very troublesome, time-consuming and labor-intensive to operate, and the hand is prone to fatigue such as soreness , which increases the great difficulty of work for the operator. Simultaneously, when people themselves carry out scraping, it is difficult to realize point scraping on the back of oneself, and the selection of back scraping point is also more difficult to realize.

The motors adopted in the present invention are all stepping motors.

Further, both ends of the pressing plate 3 are connected to the spring 5 through several connecting rods arranged parallel to each other.

Further, the scraping plate 4 is vertically arranged on the lower bottom surface of the pressing plate 3 .

As shown in Figure 1, the flat plate 12 is provided with a mounting hole 13 for fixing the bottom of the scraper; The ends are installed in the chute opposite to the frame 10; the screw A11 is also connected with a slider 14, the slider 14 is set on the connecting rod perpendicular to the screw A11, and the two ends of the connecting rod are fixed on the frame 10 on.

The working principle of the present invention: fix the bottom of the scraping device on the opening of the mounting hole 13 on the flat plate 12, make the end of the scraping plate 4 face the back of the human body, start the motor connected to the cam 2, and the cam 2 rotates , the force generated by the cam 2 on the pressure plate 3 causes the scraping plate 4 to squeeze the back of the human body. By controlling the rotation angle of the motor connected to the cam 2, the degree of extrusion of the cam 2 to the pressure plate 3 can be controlled. Squeeze force of the scraping plate 4 on the back of the human body; in order to realize the movement of the scraping device in different directions on the back of the human body, the two controllers 17 with different output frequencies can be controlled by the remote controller, and the rotation of the leading screw A11 and the leading screw B7 can be controlled respectively The two motors rotate.

When performing longitudinal scraping on the back of the human body, install the scraping device at the opening of the mounting hole 13 on the flat panel 12 according to the actual situation, and send a signal through the remote control, which is received by the controller to drive the motor fixed on the flat panel 12 to rotate, driving the active The gear 19 and the driven gear 18 are meshed and driven to realize the movement of the driven gear 18 on the lead screw A11, and then the plate 12 drives the scraping device fixed on it to move along the direction of the lead screw A11 until the scraping position on the back is found , the remote controller sends a signal to stop working; then, the remote controller sends out a signal of a different frequency than before, which is received by the controller and drives the motor fixed on the frame 10 to rotate, so that the nut 9 that is connected with it moves on the lead screw B7 , because the nut 9 is fixedly connected with the lead screw A11, the nut 9 drives the lead screw A11 to move together, so that the plate 12 drives the scraping device fixed thereon to move on the two slide bars 16. When starting scraping, start the motor connected to the cam 2 to rotate the cam 2, apply force to the scraping plate 4 through the pressure plate 3, so that the scraping plate 4 can scrape the human body, and the vertical movement range of the scraping on the back is controlled by the remote control , after a back and forth operation, the adaptive function of the integrated circuit chip in the controller memorizes the working range of scraping, and then it can repeat the previous work automatically until the remote control sends out a stop signal.

When performing horizontal scraping on the back of the human body, scrape from the edge of the back spine to both sides, which is a commonly used technique in scraping. According to the actual situation, install the scraping device on the opening of the mounting hole 13 on the flat plate 12, and send a signal through the remote control, which is received by the controller, drives the motor fixed on the frame 10 to rotate, and realizes that the nut 9 connected with it is on the lead screw B7 Up movement, because the nut 9 is fixedly connected with the lead screw A11, the nut 9 drives the lead screw A11 to move together, and the plate 12 drives the scraping device fixed on it to move on the two sliding rods 16 until the scraping position on the back is found, and the remote control The controller sends out a signal to stop working; then, the remote controller sends out a signal with a different frequency than before, which is received by the controller, drives the motor fixed on the flat panel 12 to rotate, drives the driving gear 19 and the driven gear 18 to mesh and drive, and realizes the driven The movement of the gear 18 on the lead screw A11 further realizes that the flat plate 12 drives the scraping device fixed on it to move along the direction of the lead screw A11. When scraping starts, the motor connected to the cam 2 is started to rotate the cam 2 and pass through the pressing plate. 3 Apply force to the scraping board 4 to make the scraping board 4 perform scraping on the human body. The lateral movement range of the scraping on the back is controlled by the remote control. After one back and forth operation, the adaptive function of the integrated circuit chip in the controller is memorized The working range of scraping can repeat the previous work automatically until the remote control sends a stop signal.

In order to realize the vertical and horizontal scraping on the back of the human body, the scraping board used in the present invention has an L-shaped or mouth-shaped structure.

The present invention can also realize spot scraping on the back of the human body. The motor fixed on the flat panel 12 is controlled by the remote controller to rotate, so as to realize the horizontal or vertical movement of the flat panel 12 on the back. signal, and then start the motor that controls the rotation of the cam 2, so that the cam 2 rotates, and the force exerted by the cam 2 on the pressure plate 3 makes the scraping plate 4 perform point scraping on the back. The rotation angle is realized.
