[0028] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with examples and drawings. The exemplary embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0029] Example:

[0030] See attached Figure 1 To the attached Figure 5 , anesthesia care preparation device, including a base 1, see attached Figure 2 A rotatable rotating rod 2 is provided at the top of the base 1, a control module 12 is provided inside the base 1, a built-in display screen 13 is provided on the side wall of the base 1, a rotating motor 14 is provided inside the base 1, and the bottom of the rotating rod 2 extends into the base 1 and is connected to the output shaft end of the rotating motor 14.

[0031] The top of the rotating rod 2 is provided with an annular plate 3 which is arranged around the rotating rod 2 and can rotate with the rotating rod 2. The bottom of the annular plate 3 is provided with a functional rod 4 which is movably connected to the annular plate 3. Figure 6 In this embodiment, a circular ring 27 is provided between the top of the functional rod 4 and the bottom of the annular plate 3, passing through the top of the functional rod 4 and the bottom of the annular plate 3 in sequence. The circular ring 27 is freely rotatable relative to the functional rod 4 and the annular plate 3. The functional rod 4 can lift the end of the functional rod 4 connected to the annular plate 3 away from the base 1. The sidewall of the rotating rod 2 in this embodiment is provided with an annular groove 15 surrounding the rotating rod 2. The side of the annular plate 3 facing the rotating rod 2 is provided with an annular block 16 surrounding the rotating rod 2 and located within the annular groove 15. The annular block 16 is welded to the annular plate 3 and is rotatable within the annular groove 15. The top and bottom of the annular block 16 are provided with springs 17 arranged along the annular direction of the annular groove 15, and the springs 17 are bonded to the inner wall of the annular groove 15.

[0032] The top of the base 1 is equipped with an annular groove 2 5 surrounding the rotating rod 2. The bottom of the groove 2 5 is undulating, and the bottom surface of the functional rod 4 is curved. When the rotating rod 2 rotates, driving the annular plate 1 3, the annular plate 1 3 drives the functional rod 4 to slide along the circular direction of the groove 2 5. Because the bottom of the groove 2 5 is undulating and the functional rod 4 and the annular plate 1 3 are connected by a ring 27, the functional rod 4 moves up and down with the end of the annular plate 1 3 connected to the functional rod 4, thereby shaking the annular plate 1 3 up and down, mixing the liquid medicine on the annular plate 1 3.

[0033] The side of the functional rod 4 facing the rotating rod 2 is provided with a horizontally arranged connecting rod 6, which is welded to the functional rod 4. The outer wall of the rotating rod 2 is provided with an annular plate 3 (7) surrounding the rotating rod 2. The connecting rod 6 is located at the bottom of the annular plate 3 (7). When the bottom end of the functional rod 4 is at the lowest end of the annular groove 2 (5), the annular plate 3 (7) is arranged horizontally, and the top surface of the connecting rod 6 is in contact with the bottom surface of the annular plate 3 (7). When the bottom end of the functional rod 4 is at the highest end of the annular groove 2 (5), the connecting rod 6 pushes the end of the connecting rod 6 that contacts the annular plate 3 (7) away from the base 1. Therefore, when the rotating rod 2 drives the annular plate 1 (3), the functional rod 4 rotates with it, driving the connecting rod 6 to continuously move the annular plate 3 (7) up and down along the annular direction of the annular plate 3 (7), mixing the liquid medicine on the annular plate 3 (7).

[0034] The bottom end of the rotating rod 2 of this embodiment is provided with an annular plate 2 18 which is arranged around the rotating rod 2 and does not rotate with the rotating rod 2. The outer wall of the rotating rod 2 is provided with an annular groove 3 19 which is arranged around the rotating rod 2. The side of the annular plate 2 18 facing the rotating rod 2 is provided with an annular slider 20 which is located in the annular groove 3 19 and can rotate in the annular groove 3 19 relative to the rotating rod 2. The annular slider 20 is welded to the annular plate 3 7. The bottom of the annular plate 2 18 is provided with a support rod 21 connected to the top of the base 1. The support rod 21 is welded to both the annular plate 2 18 and the base 1.

[0035] In this embodiment, a spring 22 arranged around the rotating rod 2 is provided between the bottom of the annular plate 3 7 at one end close to the rotating rod 2 and the top of the annular plate 2 18. The spring 22 is bonded to both the annular plate 2 18 and the annular plate 3 7. The spring 22 is provided with a rubber cloth 23 arranged around the rotating rod 2 on both the side facing the rotating rod 2 and the side away from the rotating rod 2. The rubber cloth 23 is bonded to both the annular plate 2 18 and the annular plate 3 7. The rubber cloth 23 on both sides can cover the spring 22.

[0036] See attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 4The tops of both annular plates 1 (3) and 3 (7) are each provided with a plurality of fixed assemblies evenly spaced along the annular direction of the corresponding annular plates 1 (3) and 3 (7). The fixed assemblies include a disc-shaped movable plate 8 and an annular track 9 located on the tops of the corresponding annular plates 1 (3) and 3 (7). The annular track 9 is welded to the corresponding annular plates 1 (3) and 3 (7). The center of the annular track 9 is provided with a pin 10 located on the tops of the corresponding annular plates 1 (3) and 3 (7). The bottom of the pin 10, i.e., the end with the smaller cross-sectional area of the pin 10, is welded to the corresponding annular plates 1 (3) and 3 (7). The bottom end of the pin 10 passes through one end of the movable plate 8, allowing the movable plate 8 to rotate relative to the pin 10 with the pin 10 as the center of the circle. The end of the movable plate 8 away from the pin 10 is located on the top of the annular track 9.

[0037] See attached Figure 5 The top surface of the annular track 9 is wavy and undulating. The bottom surface of the movable plate 8 is provided with a wavy protrusion 11 at the position where it contacts the annular track 9. The cross section of the protrusion 11 is arc-shaped, and the protrusion 11 fits with the top surface of the annular track 9.

[0038] When annular plate 1 3 and annular plate 3 7 are lifted and tilted by functional rod 4, movable plate 8 also tilts accordingly. As functional rod 4 moves around rotating rod 2, the edges of annular plate 1 3 and annular plate 3 7 are successively lifted, and the tilting direction of movable plate 8 also successively changes. Due to the effect of gravity, movable plate 8 will now rotate continuously relative to pin 10 and along the circular direction of annular track 9. Protrusion 11 slides on the wavy top surface of annular track 9, thereby lifting or lowering movable plate 8, thereby shaking movable plate 8 and achieving the purpose of further mixing the liquid medicine.

[0039] See attached for details Figure 3 In this embodiment, the top surface of the movable plate 8 is tilted, and the lower end of the top surface of the movable plate 8 is located on the side away from the pin 10. The tilted top surface of the movable plate 8 can further increase the range of movement of the liquid medicine in the medicine bottle.

[0040] See attached for details Figure 3 and attached Figure 4 A medicine bottle clamp is provided on the top of the movable plate 8. The medicine bottle clamp of this embodiment includes a connecting plate 24 arranged perpendicular to the top surface of the movable plate 8. The side wall of the connecting plate 24 facing away from the pin 10 is provided with a clamping cylinder 25 made of elastic plastic material. The connecting plate 24 is bonded to the movable plate 8 and the clamping cylinder 25. A notch 26 is provided on the side of the clamping cylinder 25 away from the connecting plate 24.

[0041] The operating principle of this embodiment is as follows: the device is controlled by the control module 12. When in use, the parameters are set and the rotation motor 14 is controlled through the embedded display screen 13. The rotation speed of the rotation motor 14 is 5-30rpm. The prepared liquid medicine bottle is pressed from the top of the clamping cylinder 25 into the clamping cylinder 25, and the clamping cylinder 25 clamps the bottle; before the device starts to operate, the bottom of the functional rod 4 is located at the lowest end of the annular groove 2 5, and the annular plate 1 3 and the annular plate 3 7 are both in a horizontal position; turn on the rotation motor 14, drive the rotating rod 2 to rotate, and the rotating rod 2 drives the annular plate 1 3 The annular plate 1 3 rotates, driving the functional rod 4 to rotate. The functional rod 4 slides in the annular groove 2 5 along the annular direction of the annular groove 2 5. The wavy bottom surface of the annular groove 2 5 successively pushes the functional rod 4 upward and lowers the functional rod 4 downward, thereby driving the functional rod 4 to push up or lower the annular plate 1 3. The connecting rod 6 pushes up or lowers the annular plate 3 7. In addition to the centrifugal mixing force, the liquid medicine on the top of the annular plate 1 3 also has the up and down shaking force caused by the functional rod 4, thereby mixing the liquid medicine. The liquid medicine on the top of the annular plate 3 7 is mixed by the up and down shaking force.

[0042] When the annular plate 1 3 rotates, the functional rod 4 and the connecting rod 6 rotate accordingly, thereby lifting and lowering the corresponding annular plate 1 3 and annular plate 3 7 in various directions. When the annular plate 1 3 and annular plate 3 7 are lifted up, the annular plate 1 3 and annular plate 3 7 are tilted, and the movable plate 8 on the surface thereof will also tilt. The movable plate 8 is acted upon by gravity and will continuously rotate with the pin 10 as the center of the circle. When it rotates, it will shake the liquid medicine in the bottle, thereby further mixing the liquid medicine. At the same time, the wavy annular track 9 will continuously lift and lower the movable plate 8, generating a force perpendicular to the movable plate 8 on the liquid medicine on the movable plate 8, thereby further mixing the liquid medicine.

[0043] The device generates multiple directions of chaotic and far-to-near forces on the liquid medicine through a single driving force, which can mix the liquid medicine in a shorter time and has high mixing efficiency.

[0044] The above are embodiments of the present invention. The above embodiments and the specific parameters therein are only for the purpose of clearly describing the invention verification process and are not intended to limit the scope of protection of the present invention. The scope of protection of the present invention shall still be subject to the claims.
