[0002] Prior invention 2025107313791 discloses a high-pressure injector for automatically inserting and removing a liquid medicine bottle and a control method thereof. A bottle inserting seat 20 with an automatic inserting and removing liquid medicine bottle 30 is provided on the top of the host 10. The structure thereof is as follows: Figure 1 and Figure 2 However, this patent only considers the ideal working state, such as Figure 3 As shown, the axis of the liquid medicine bottle 30 almost overlaps with the axis of the inner cavity 22, and each roller 23 can rotate at a constant speed to pull the liquid medicine bottle 30 down or up. When pulling out the bottle, because the initial state basically meets the ideal, there is no problem with the constant speed rotation. However, when inserting the bottle, in the initial state, the liquid medicine bottle 30 is placed at the opening of the inner cavity 22 by hand, which makes it difficult to ensure that the ideal state is met at the start. More may occur as follows Figure 4 In the situation shown, there is a large angle between the axis of the medicine bottle 30 and the axis of the inner cavity 22. If the roller 23 is rotated at a constant speed at this time, problems such as ectopic puncture and bottle jamming are likely to occur. Summary of the Invention

[0026] The bottle inserting seat for automatically inserting a bottle of a high-pressure syringe described in the present invention has a structure as follows: Figure 5 and Figure 6 As shown, it is fixedly mounted on the top of the main unit 10 and is used to place a medicine bottle 30. The bottle holder 20 includes a shell 21, and an inner cavity 22 for accommodating the medicine bottle 30 is formed in the shell 21. A needle connected to the high-pressure injection line is provided at the bottom of the inner cavity 22. The shell 21 is provided with a plurality of rollers 23 on the side wall of the inner cavity 22. The plurality of rollers 23 are evenly distributed around the central axis of the inner cavity 22. The rotating shaft of the roller 23 is installed in the shell 21, and the rotation direction is controlled by a micromotor. The micromotor is electrically connected to the main unit 10 and is controlled by the main unit 10. The roller 23 extends from the shell 21 to the inner cavity 22, and is used to drive the medicine bottle 30 in the inner cavity 22 to move up and down.

[0027] The housing 21 is also equipped with several laser rangefinders 25, each corresponding to the rollers 23. A vertically extending longitudinal light guide 26 is provided above the laser rangefinder 25. The lower end of the longitudinal light guide 26 corresponds to the laser port of the laser rangefinder 25, and the upper end is connected to a horizontally extending transverse light guide 27. The transverse light guide 27 is located above the corresponding roller 23. The end of the transverse light guide 27 away from the longitudinal light guide 26 extends to the side wall of the inner cavity 22. A 45-degree reflector 28 is provided at the connection between the longitudinal light guide 26 and the transverse light guide 27. The laser rangefinder 25 uses the corresponding longitudinal light guide 26 and transverse light guide 27 to detect the distance to the liquid medicine bottle 30 and feedback it to the host 10. The host 10 adjusts the rotation speed of the corresponding roller 23 based on the current distance.

[0028] The longitudinal light guides 26 and the transverse light guides 27 are optical fibers.

[0029] The number of the laser rangefinders 25 and the number of the rollers 23 are both six.

[0030] The present invention provides a correction method for the bottle holder, wherein the host 10 obtains the maximum and minimum values of the distances measured by all laser rangefinders 25; and controls the rotation speed of the corresponding roller 23 according to the relationship between the distance measured by any laser rangefinder 25 and the maximum and minimum values. The greater the deviation from the maximum value, the greater the suppression of the rotation speed of the corresponding roller 23.

[0031] The rotation speed Vi of the roller 23 with serial number i satisfies the following relationship:

[0032]

[0033] Among them, i is the serial number of the roller 23 and the corresponding laser rangefinder 25; Li is the distance measured by the laser rangefinder 25 with serial number i; Lmax is the maximum value; Lmin is the minimum value; V0 is the rated speed of the roller 23, and α is the sensitivity coefficient and is greater than or equal to 1.

[0034] When the liquid medicine bottle 30 is placed randomly at the opening of the inner cavity 22 and tilted naturally, the distance data measured by the laser rangefinder 25 is generally symmetrical. Since the distance is expressed in a ratio, it can be expressed in units of distance. Some examples are shown in Tables 1 and 2:

[0035] Table 1

[0036]

[0037]

[0038] Table 3

[0039]

[0040] The above tables show that the closer the medicine bottle 30 is tilted, the more its rotational speed is suppressed. The higher the sensitivity coefficient, the more dramatic the suppression effect. Therefore, the corresponding roller 23 on the other side will rotate at its full rated speed, applying asymmetrical force to push the medicine bottle 30 toward an increasingly vertical position. When the distances between the laser rangefinders 25 are consistent, all rollers 23 will also drive the medicine bottle 30 at their rated speed, ensuring an ideal vertical position when the needle is inserted.

[0041] Those skilled in the art can make various other corresponding changes and deformations based on the technical solutions and concepts described above, and all of these changes and deformations should fall within the scope of protection of the claims of the present invention.
