DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0020] Example 1: Please refer to Figure 1-6 The present invention provides a technical solution: an insulin injection positioning device for abdominal injection, comprising a positioning block 1, wherein the left and right sides of the positioning block 1 are movably connected with restraint belts 2, wherein an outer wall of one of the restraint belts 2 is provided with a navel hole 3, a skin pinching component 4 is fixedly connected to the outer wall of the positioning block 1, and a positioning mechanism 5 is provided inside the positioning block 1; The skin pinching component 4 comprises: A rubber block 401, which is fixedly connected to the bottom of the positioning block 1; A clamping block 402, which is disposed on the back of the positioning block 1, and a rubber block 401 is fixedly connected to the bottom of the clamping block 402; The pull gear rod 403 is movably connected to the inside of the positioning block 1 , and the pull gear rod 403 is fixedly connected to the front side of the clamping block 402 .

[0021] The device is bound to the injection area through the restraint belt 2, and the navel hole 3 is located on the outer circle of the navel to assist the positioning block 1 in positioning the injection area. The toothed rod 403 is pulled toward one side of the positioning block 1 to move the clamping block 402 toward the positioning block 1. During the movement, the clamping block 402 provides friction, so that the positioning block 1 and the clamping block 402 are fitted together, and the skin is pinched between the positioning block 1 and the clamping block 402.

[0022] A rotating rod 404 is movably connected to the front of the positioning block 1 , and the outer wall of the rotating rod 404 is provided with teeth meshing with the pulling gear rod 403 , and a rotating handle 405 is fixedly connected to the left side of the pulling gear rod 403 .

[0023] The rotating handle 405 is rotated to rotate the rotating rod 404, and the rotating rod 404 pulls the pulling gear rod 403 through the teeth provided on the outer wall, so that the clamping block 402 moves toward the positioning block 1 to pull up the patient's skin.

[0024] The right side of the positioning block 1 is located on the left side of the rotating rod 404 and is movably connected with a pawl plate 411. The outer wall of the rotating rod 404 is located at a corresponding position of the pawl plate 411 and is fixedly connected with an outer ring ratchet 406. The pawl plate 411 will limit the turning of the rotating rod 404 through the outer ring ratchet 406. The top of the pawl plate 411 is fixedly connected with a first spring 407. The top of the first spring 407 is fixedly connected with a limiting plate 408, and the limiting plate 408 is fixedly connected to the front of the positioning block 1. The end of the pawl plate 411 close to the positioning block 1 will be pulled by the first spring 407, and then the pawl plate 411 will fit the outer wall of the outer ring ratchet 406, so that the pawl plate 411 limits the rotation direction of the rotating rod 404 through the outer ring ratchet 406.

[0025] During the rotation of the rotating rod 404, the outer ring ratchet 406 will also be rotated, and the outer ring ratchet 406 will push the ratchet plate 411 to rotate. When the skin is pinched to a suitable thickness, the rotating handle 405 is released. At this time, the outer ring ratchet 406 will be restricted in the direction of rotation by the ratchet plate 411. At this time, the positions of the positioning block 1 and the clamping block 402 will be fixed to avoid interference in loosening the skin pinch, and then use the injection needle to inject insulin.

[0026] A pressing rod 409 is fixedly connected to the top of the first spring 407 inside the limiting plate 408 , and a pressing plate 410 is fixedly connected to the top of the pressing rod 409 .

[0027] After the injection is completed, the pressing rod 409 is pressed down by pressing the pressing plate 410, so that the pressing rod 409 presses the ratchet plate 411, so that the first spring 407 is pulled up, and the ratchet plate 411 rotates around the connection with the positioning block 1, so that the ratchet plate 411 no longer restricts the rotation direction of the outer ring ratchet 406 through the outer ring ratchet 406. At this time, the clamping block 402 and the positioning block 1 will move away from each other under the elasticity of the skin, and pull back the gear rod 403.

[0028] Example 2: Please refer to Figure 1-14 Based on the first embodiment, the present invention provides a technical solution: The positioning mechanism 5 includes a ratchet 501, which is arranged inside the positioning block 1. The top of the ratchet 501 is movably connected to a moving rod 508, the top of the moving rod 508 is fixedly connected to a horizontal plate 509, the top of the horizontal plate 509 is fixedly connected to a movable platform 510, and the top of the movable platform 510 is movably connected to a guide needle holder 511.

[0029] When the clamping block 402 and the positioning block 1 are pinching the skin, the injection needle is allowed to pass through the needle guide frame 511 to perform injection, and the inner wall of the needle guide frame 511 will be closely attached to the injection needle.

[0030] The horizontal plate 509 is movably connected to the inside of the positioning block 1, and the horizontal plate 509 is limited by the inner wall of the positioning block 1 to only move horizontally. The inside of the positioning block 1 is movably connected to a tooth plate 502 at the top of the ratchet 501. The bottom of the tooth plate 502 is provided with teeth that cooperate with the ratchet 501. The top of the tooth plate 502 is fixedly connected to a second spring 506. The top of the second spring 506 is fixedly connected to the inner wall of the positioning block 1. The tooth plate 502 is limited by the inner wall of the positioning block 1 to only move up and down. Fig.11 As shown in the figure, the ratchet 501 can only rotate clockwise. When the movable rod 508 moves to the left, it drives the ratchet 501 to move to the left, and the outer teeth of the ratchet 501 interact with the teeth at the bottom of the tooth plate 502 to rotate clockwise. When the ratchet 501 is moved to the right, the ratchet 501 cannot rotate, and is restricted by the teeth of the tooth plate 502, so that the ratchet 501 cannot move to the right.

[0031] During each injection, the needle guide frame 511 is pushed to move a certain distance in the movable direction, so that the position of the needle guide frame 511 is changed, and then the injection needle is passed through the needle guide frame 511 for injection.

[0032] Since the needle guide frame 511 is restricted by the moving rod 508 to move in only one direction, continuous acupuncture at one position is prevented.

[0033] A movable frame 503 is movably connected to the bottom of the tooth plate 502 inside the positioning block 1, and a limiting groove 505 is provided inside the positioning block 1. The limiting groove 505 will limit the range of movement of the movable frame 503. The outer wall of the movable frame 503 is located on the left and right sides of the tooth plate 502 and is fixedly connected to a pushing column 504. The top of the movable frame 503 is located at the bottom of the tooth plate 502 and is fixedly connected to a lifting rod 507.

[0034] When the moving rod 508 moves to the outermost edge of the movable side, it will push the pushing column 504 to the flat part corresponding to the limiting groove 505, push the tooth plate 502 through the lifting rod 507 and let the second spring 506 shrink. At this time, the outer teeth of the ratchet 501 are no longer engaged with the teeth of the tooth plate 502. At this time, the moving rod 508 is moved in the opposite direction to the outermost edge, and then the movable frame 503 is pushed by another pushing column 504, so that the second spring 506 can push the tooth plate 502 to reset, so that the teeth of the tooth plate 502 are engaged with the teeth of the ratchet 501 again to limit the rotation direction of the ratchet 501.

[0035] A limiting protrusion 513 is fixedly connected to the bottom of the guide needle frame 511, and a clamping strip 514 is fixedly connected to the back of the positioning block 1 located at the bottom of the guide needle frame 511. A third spring 512 is arranged between the guide needle frame 511 and the movable platform 510, and the two ends of the third spring 512 are respectively fixedly connected to the guide needle frame 511 and the movable platform 510. A scale mark 515 is arranged on the top of the positioning block 1, and the movable platform 510 will fit the scale, thereby playing the role of indicating the scale. When the guide needle frame 511 moves, the scale mark 515 can be referred to to control the moving distance.

[0036] When the injection needle passes through the guide needle holder 511 for injection, the guide needle holder 511 is pressed down to allow the limiting protrusion 513 to be inserted into the clamping strip 514 to prevent the guide needle holder 511 from moving in the movable direction of the moving rod 508, thereby preventing the movement of the needle from causing damage to the patient's skin. When the guide needle holder 511 is fixed by the limiting protrusion 513 through the clamping strip 514, the position of the guide needle holder 511 relative to the positioning block 1 is fixed, so that the relative position of the injection needle and the positioning block 1 is fixed. Since the positioning block 1 and the clamping block 402 clamp the skin, the position of the injection needle and the skin is fixed, thereby being able to resist external interference.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
