Description

Technical Field

[0001] The utility model relates to the technical field of drug configuration mixing devices, and more specifically, to a mixing device. Background Art

[0002] During the preparation of intravenous drugs, a certain amount of solvent or corresponding solvent is drawn with a syringe and injected into the vial containing the drug to dissolve the drug, and then the dispensing personnel manually shake the vial to fully mix the drug with the solvent or reagent. The mixed drug is then drawn and injected into the infusion bag or bottle containing the solvent, thus completing the preparation of the intravenous drug.

[0003] This method has its shortcomings. Manual shaking is not only time-consuming and laborious, but also the shaking angles, amplitudes and shaking trajectories are all different, making it impossible to achieve a unified standard. The reliability of drug dissolution is poor, and some drugs can only be repeatedly inverted when mixed and cannot be shaken. It is difficult to achieve this requirement using manual methods, so improvements are urgently needed. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 4 As shown, a mixing device includes a base plate 1 and a carrying plate 2, support plates 11 are provided on both sides of the base plate 1, and the carrying plate 2 is located between the two support plates 11. Rotating shafts 21 are provided on both sides of the carrying plate 2, and the rotating shafts 21 penetrate the support plates 11. Rotating the rotating shafts 21 can drive the carrying plate 2 to rotate. A plurality of placement grooves 22 are provided on the surface of the carrying plate 2. When in use, a medicine bottle injected with liquid medicine is placed in the placement groove 22, and the rotating shafts 21 can be rotated to drive the carrying plate 2 to rotate, so that the liquid medicine in the medicine bottle can be fully mixed. In this way, the shaking angle, amplitude and shaking trajectory of the medicine bottle are unified, and the degree of standardization is high, so that the liquid medicine is mixed more fully.

[0024] A limiting sleeve 12 is provided on the outer side of the support plate 11 on one side, and a slider 3 capable of moving along the length direction of the rotating shaft 21 is provided on the outer side of the rotating shaft 21. The slider 3 can be inserted into the limiting sleeve 12 to limit the rotation of the supporting plate 2. Specifically, the cross-section of the rotating shaft 21 and the support plate 11 is circular, and the cross-section of the rotating shaft 21 and the slider 3 is non-circular. The slider 3 rotates synchronously with the rotating shaft 21. A limiting groove 13 is provided inside the limiting sleeve 12, and a limiting platform 14 is provided inside the limiting groove 13. The slider 3 includes an annular sleeve 31, and a convex rib 32 is provided on the outer wall of the annular sleeve 31. The annular sleeve 31 can be inserted into the limiting groove 13, and the rotating shaft 21 is rotated so that the convex rib 32 can abut against the two ends of the limiting platform 14.

[0025] When the rotating shaft 21 rotates, it can drive the slider 3 to rotate synchronously. If it is necessary to use a repeated inversion mode to mix the medicine, the annular sleeve 31 is inserted into the limiting groove 13. At this time, the rotating shaft 21 is rotated. By repeatedly rotating the supporting plate 2, repeated inversion mixing of the medicine solution can be achieved. Moreover, through the cooperation of the convex rib 32 and the limiting platform 14, the supporting plate 2 can only rotate one hundred and eighty degrees, thereby limiting the rotation of the supporting plate 2, and the rotating transition of the supporting plate 2 improves the effect of mixing the medicine solution.

[0026] The side of the annular sleeve 31 is provided with a baffle 33, and the baffle 33 can abut against or move away from the limiting sleeve 12. The side of the baffle 33 is provided with a sliding sleeve 34, and the sliding sleeve 34 is sleeved on the outside of the rotating shaft 21. The sliding sleeve 34 and the rotating shaft 21 are fixed by a first bolt 4. In this embodiment, the cross-section of the part of the rotating shaft 21 that cooperates with the slider 3 is square. When it is necessary to limit the rotation of the bearing plate 2, the annular sleeve 31 is inserted into the limiting groove 13, and the baffle 33 abuts against the side of the limiting sleeve 12. At this time, the first bolt 4 is tightened so that the end of the first bolt 4 abuts against the side of the rotating shaft 21, thereby fixing the position of the slider 3; when it is not necessary to limit the rotation of the bearing plate 2, it is only necessary to move the slider 3 so that the slider 3 is disengaged from the limiting groove 13, and then fix the position of the slider 3 by the first bolt 4.

[0027] Among them, the inner wall of the placement groove 22 is provided with a plurality of spring pieces 23. By providing the spring pieces 23, when the medicine bottle is inserted into the placement groove 22, the medicine bottle can be clamped by the spring pieces 23, thereby improving the fixing effect of the medicine bottle.

[0028] A cover plate 5 is provided above the supporting plate 2, and the cover plate 5 is connected to the supporting plate 2 through a connecting column 6. Specifically, a threaded groove 24 is provided on the surface of the supporting plate 2, and the connecting column 6 includes a threaded portion 61. The lower portion of the connecting column 6 is inserted into the threaded groove 24, and the threaded portion 61 is connected to the threaded groove 24. The cover plate 5 and the connecting column 6 are connected by a second bolt 7. The upper portion of the connecting column 6 abuts against the lower portion of the cover plate 5. A boss 62 is provided on the upper portion of the connecting column 6, and the upper portion of the boss 62 passes through the upper portion of the cover plate 5. The upper portion of the boss 62 is threadedly connected with the second bolt 7. When the medicine bottle is inserted into the placement groove 22, the connecting column 6 is screwed into the threaded groove 24 until the lower portion of the cover plate 5 abuts against the upper portion of the medicine bottle, thereby fixing the medicine bottle and effectively preventing the medicine bottle from being thrown out during the rotation of the supporting plate 2. Through the cooperation of the boss 62, the cover plate 5 and the second bolt 7, the rotational connection between the connecting column 6 and the cover plate 5 can be achieved.
