[0017] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0018] See also Figures 1 to 7 The present invention provides an injection teaching instrument for medical nursing profession, comprising a box body 1, one end of the box body 1 is fixedly connected to a storage cylinder 2, the end of the box body 1 away from the storage cylinder 2 is fixedly connected to a waste cylinder 3, the box body 1 is fixedly connected to a teaching box 4 at a position between the storage cylinder 2 and the waste cylinder 3, the outer side wall of the box body 1 close to the teaching box 4 is fixedly connected to a display mechanism 5 for displaying the injection speed, the display mechanism 5 is connected to the teaching box 4 through a pipeline, the box body 1 is provided with a sliding groove 6, and a moving mechanism 7 for driving a rubber block to move is slidably connected in the sliding groove 6.

[0019] After the rubber block is moved into the teaching box 4, injection teaching exercises are then carried out. The display mechanism 5 provided can display the injection speed accordingly, and the speed of injection can be intuitively seen, so that adjustments can be made to control the injection speed for better simulation. The scrapped rubber block can be moved into the waste barrel 3 through the moving mechanism 7 provided, and then the new rubber block in the storage barrel 2 is moved into the teaching box 4. The replacement is completed during one movement of the moving mechanism 7, and the operation is simple and the replacement speed is fast.

[0020] See also Figures 1 to 3The display mechanism 5 includes a display box 8 fixedly connected to the outer wall of the box body 1, and a scale 9 is set on the display box 8. A fixed shaft 10 is fixedly connected to the inner wall of the display box 8. A rotating seat 11 is rotatably connected to the fixed shaft 10, and a rotating rod 12 is fixedly connected to the rotating seat 11. The end of the rotating rod 12 away from the rotating seat 11 is fixedly connected to a floating ball 13. The rotating rod 12 is hinged with a connecting rod 14 at a position between the rotating seat 11 and the floating ball 13. The end of the connecting rod 14 away from the rotating rod 12 is fixedly connected to a blocking block 15. A discharge hole 16 is opened at the bottom of the display box 8, and the blocking block 15 is located in the discharge hole 16.

[0021] During injection teaching, when the injection speed is lower than the standard speed, the injected liquid enters the teaching box 4, and then enters the display box 8 through the pipeline. When the liquid level reaches the 0 scale 9, the float 13 rises due to the buoyancy of the liquid. The rise of the float 13 drives the rotating rod 12 to rotate around the fixed axis 10. The rotation of the rotating rod 12 drives the connecting rod 14 to move. The movement of the connecting rod 14 drives the blocking block 15 to move, so that the blocking block 15 no longer blocks the discharge hole 16. The size of the discharge hole 16 is set so that the flow rate of the discharged liquid is the flow rate during normal injection. At this time, the liquid is discharged through the discharge hole 16, and the liquid flows out of the discharge hole 16. The liquid The surface will be lower than the 0 scale 9. At this time, the float 13 will fall with the liquid level, and the blocking block 15 will block the discharge hole 16. Because the injection is continuing, the liquid continues to enter the display box 8, and the above process will be repeated. When the injection speed is equal to the standard speed, when the liquid reaches the 0 scale 9, because the injection speed is equal to the standard speed, the liquid level is level with the 0 scale 9. When the injection speed is greater than the standard speed, the liquid discharge speed is less than the injection speed, and the liquid level will be above the 0 scale 9 and continue to move upward, so as to detect whether the injection speed is standard, so as to control the injection speed in real time and better carry out injection teaching communication.

[0023] When it is necessary to replace the rubber block, pull the handle 18 to move in the direction away from the teaching box 4, the movement of the handle 18 drives the slide bar 17 to move, the movement of the slide bar 17 drives the moving rod 19 to move, the movement of the moving rod 19 drives the first rack 27 to move, the movement of the first rack 27 drives the driving gear 30 to rotate, the rotation of the driving gear 30 drives the rotating shaft 29 to rotate, the rotation of the rotating shaft 29 drives the cam 31 to rotate, the cam 31 rotates to push the rubber block out of the teaching box 4, when the cam 31 pushes the rubber block out of the teaching box 4, the driving gear 30 disengages from the first rack 27, and when the moving rod 19 continues to move , the sliding rod 21 will move along the pushing groove 20, so that the sliding rod 21 moves in the direction close to the rubber block, the sliding rod 21 moves to drive the fixed block 22 to move, the fixed block 22 moves to drive the clamping rod 25 to move, the clamping rod 25 moves to drive the clamping block 26 to move, the clamping block 26 moves to clamp the rubber block, and when the moving rod 19 continues to move, the sliding rod 21 moves to the tail end of the pushing groove 20, so that the moving rod 19 moves to drive the sliding rod 21 to move, and then drives the rubber block to move, so that the rubber block moves to the waste barrel 3, and then moves in the opposite direction, and the sliding rod 21 moves along the pushing groove 20, The clamping block 26 no longer clamps the rubber block. When the sliding rod 21 moves to the other end of the pushing groove 20, the moving rod 19 will drive the sliding rod 21 to move, thereby returning to the initial position. When the rubber block moves to the waste barrel 3, the center of the rubber block is located in the waste barrel 3. The moving distance is greater than the general length of the rubber block. When the clamping block 26 no longer clamps the rubber block, because the center of the rubber block is located in the waste barrel 3, the rubber block will fall into the waste barrel 3 under the action of gravity. When the moving rod 19 moves toward the waste barrel 3, the moving rod 19 will drive the pushing assembly 32 to move to the bottom of the storage barrel 2 The blocking component 33 no longer blocks the rubber block in the storage tube 2, so that the rubber block falls onto the pushing component 32. When the moving rod 19 returns to the initial position, the moving rod 19 will drive the pushing component 32 to move the new rubber block to the teaching box 4, thereby completing the replacement of the rubber block. The rubber block can be replaced by only pulling the handle 18 back and forth once, which improves the replacement speed of the rubber block and simplifies the replacement operation. The blocking component 33 prevents the rubber block from falling during the replacement process of the rubber block, so that the rubber block can only fall onto the pushing component 32, ensuring the normal replacement of the rubber block.

[0024] See also Figure 4The pushing assembly 32 includes a driving rack 34 slidably connected to the inner wall of the box body 1, and a connecting gear 35 is rotatably connected to the inner wall of the box body 1 near the teaching box 4 through a rotating shaft. A passive rack 36 is slidably connected to the inner wall of the box body 1 near the connecting gear 35, and the passive rack 36 and the driving rack 34 are both meshed with the connecting gear 35. A pushing rod 37 is fixedly connected to one end of the two passive racks 36 near the teaching box 4, and a limiting strip 38 for limiting the rubber block is fixedly connected to the pushing rod 37, and a top block 39 is symmetrically fixedly connected to the top of the pushing rod 37.

[0025] When the moving rod 19 moves, the moving rod 19 drives the driving rack 34 to move, the movement of the driving rack 34 drives the connecting gear 35 to rotate, the rotation of the connecting gear 35 drives the passive rack 36 to move, the movement of the passive rack 36 drives the pushing rod 37 to move, the movement of the pushing rod 37 drives the rubber block to move, so that the rubber block moves into the teaching box 4, the limit bar 38 limits the rubber block to prevent the rubber block from deviating from the predetermined position during the movement, the top block 39 conflicts with the blocking assembly 33, so that the rubber block falls between the pushing rod 37 and the limit block.

[0026] See also Figure 6 The blocking assembly 33 includes a fixed base 40 fixedly connected to the box body 1 and located below the storage cylinder 2, and rotating blocks 41 are rotatably connected on both sides of the fixed base 40. A blocking rod 42 is fixedly connected to each rotating block 41, and an elastic rope 43 is fixedly connected between the two blocking rods 42.

[0027] When the top block 39 moves toward the waste barrel 3, the blocking rods 42 are driven closer to each other under the action of the elastic rope 43, so that the blocking rods 42 block the rubber block to prevent the rubber block from falling. When the top block 39 moves toward the storage barrel 2, the top block 39 collides with the blocking rod 42, and the top block 39 overcomes the elastic rope 43 to move the blocking rod 42 away from each other, causing the rubber block to fall between the push rod 37 and the limit rod.

[0028] See also Figure 1 The top block 39 abuts against the blocking rod 42 to move the two blocking rods 42 away from each other, so that the blocking rod 42 no longer blocks the rubber block, and the rubber block falls between the pushing rod 37 and the limiting rod.

[0029] See also Figure 7 The width of the portion of the push rod 37 between the limit strips 38 gradually decreases from top to bottom. When one end of the rubber block moves into the teaching box 4, the other end is pressed into the teaching box 4 under the action of the push rod 37, so that the rubber block relatively seals the teaching box 4, so that the injected liquid level can flow into the display box 8 through the pipeline.

[0030] See also Figure 4One end of the driving rack 34 is fixedly connected to the moving rod 19. When the moving rod 19 moves, the moving rod 19 can drive the driving rack 34 to move.

[0031] See also Figure 4 The two moving rods 19 are fixedly connected to a connecting rod 44 at one end close to the handle 18. When the handle 18 is pulled, the moving rods 19 on both sides of the inner wall of the box body 1 are moved simultaneously through the connecting rod 44.

[0032] See also Figure 1 The display box 8 is made of a transparent material, so that the scale 9 at which the liquid level in the display box 8 is located can be clearly seen.
