[0033] The present invention will now be described in detail.

[0034] like Figures 1-5 As shown:

[0035] A vial pre-dissolving device for dispensing and mixing vials 100; comprising a base 1, a turntable 2 mounted on the base 1 and rotatably cooperating with the base 1 in a horizontal direction, a clamping mechanism 3 mounted on the turntable 2 for clamping vials 100, a pick-and-place mechanism 4 mounted on the base 1 for picking up and placing vials 100 clamped by the clamping mechanism 3, and a dispensing mechanism 5 mounted on the base 1 for dispensing vials 100.

[0036] A turntable 2 is rotatably mounted on a base 1, and a clamping mechanism 3 is mounted on the turntable 2. The rotation of the turntable 2 causes the vial 100, which is clamped by the clamping mechanism 3, to rotate, allowing the vial 100 to rotate below the dispensing mechanism 5 for dispensing. After all vials 100 on the turntable 2 have been dispensed, the medication is shaken evenly by the forward and reverse rotation of the turntable 2. After the medication is shaken evenly, the vial 100 held by the clamping mechanism 3 is removed by the pick-and-place mechanism 4 in cooperation with the pick-and-place mechanism 3. This effectively achieves automated medication dispensing and shaking. The pick-and-place mechanism 4 prevents injury to medical personnel when the vials 100 are manually removed. Compared to existing technologies that use vibration for shaking, this invention uses the rotation of the turntable 2 to drive the vial 100 to rotate at high speed, achieving higher work efficiency and preventing the vial 100 from falling off due to excessive vibration.

[0037] In some possible implementations, the turntable 2 is annular, and the clamping mechanism 3 is in multiple sets and evenly arranged around the circumference of the turntable 2. The multiple sets of clamping mechanisms 3 can clamp and fix multiple sets of vials 100, thereby realizing batch efficient dispensing and mixing of the same drug solution; the pick-and-place mechanism 4 is located inside the inner ring of the turntable 2; the clamping mechanism 3 is installed on the turntable 2, and the vial 100 clamped by the clamping mechanism 3 will be located outside the outer ring of the turntable 2.

[0038] Specifically, the turntable 2 is rotatably coupled with the base 1. A rotary drive mechanism connected to the turntable 2 is provided on the base 1. The rotary drive mechanism controls the turntable 2 to rotate forward and backward on the base 1. The rotary drive mechanism is existing technology, and its internal structure will not be described in detail here.

[0039] In some possible implementations, the pick-and-place mechanism 4 includes a support column mounted on the base 1 and a telescopic mechanism 41 mounted on the support column and extending and retracting in the horizontal direction; the support column is coaxially arranged with the turntable 2 and fitted inside the turntable 2, there is a gap between the support column and the inner ring of the turntable 2, and the telescopic mechanism 41 will be located above the turntable 2.

[0040] After the liquid in the vial 100 is shaken evenly, the telescopic mechanism 41 will move closer to the clamping mechanism 3 and engage with the clamping mechanism 3 in a transmission manner, causing the vial 100 to fall.

[0041] Specifically, the telescopic mechanism 41 includes a telescopic cylinder mounted on the support column and an abutment plate 42 mounted on the output end of the telescopic cylinder. The telescopic cylinder controls the abutment plate 42 to move closer to the clamping mechanism 3 and engage with the clamping mechanism 3 to achieve the dislodgement of the vial 100 clamped on the clamping mechanism 3 and drop it into the storage box. The storage box is equipped with a cushioning pad, and since the vial 100 has a thick wall, it will not be damaged.

[0042] In some possible implementations, the clamping mechanism 3 includes two sets of clamping bodies 31 arranged facing each other and close to one side to form a clamping cavity 311, and a drive assembly 32 connected to the clamping bodies 31 and used to control the size of the clamping cavity 311; the drive assembly 32 is mounted on the turntable 2.

[0043] The drive assembly 32 is mounted on the turntable 2. Before clamping the vial 100, the drive assembly 32 controls the size of the clamping cavity 311 to increase, so that the vial 100 can be located in the clamping cavity 311. Then, the drive assembly 32 controls the two sets of clamping bodies 31 to move closer to each other, reducing the size of the clamping cavity 311, so that the two sets of clamping bodies 31 clamp and fix the outside of the vial 100. After the vial 100 is installed on all the clamping mechanisms 3, the turntable 2 will rotate, so that one set of clamping mechanisms 3 and the vial 100 can rotate to be directly below the dispensing mechanism 5. Then the dispensing mechanism 5 performs the dispensing operation.

[0044] In some possible implementations, the drive assembly 32 includes a chassis 321 mounted on the turntable 2, a drive block 322 slidably mounted on the chassis 321 and moving radially along the turntable 2, two sets of connecting arms 323 with one end hinged to the clamping body 31 and the other end hinged to the drive block 322, and an elastic element 324 mounted on the chassis 321 and connected to the drive block 322; the side of the drive block 322 away from the pick-and-place mechanism 4 is slidably engaged with the clamping body 31, and the sliding direction of the clamping body 31 is perpendicular to the sliding direction of the drive block 322; the two sets of connecting arms 323 are arranged one-to-one with the clamping body 31 and form a figure-eight structure, with the small end of the figure-eight structure located near the drive block 322.

[0045] The chassis 321 is bolted to the turntable 2. The drive block 322 slides with the chassis 321 along the radial direction of the turntable 2. By controlling the two sets of clamping bodies 31 to move away from each other, the included angle formed by the two sets of connecting arms 323 becomes larger. At this time, the elastic element 324 will be in a stretched state, so that the vial 100 is installed in the mounting cavity. Then, no force is applied to the clamping body 31, and the elastic element 324 will return to the initial state, so that the two sets of clamping bodies 31 move closer to each other, thereby achieving the clamping of the vial 100.

[0046] The elastic element 324 is a compression spring, and its axis is parallel to the sliding direction of the drive block 322. There are two sets of elastic elements 324, and the drive block 322 will be located between the two sets of elastic elements 324, so that the drive block 322 is balanced by force and avoids instability.

[0047] After the liquid in the vial 100 is shaken evenly, the turntable 2 rotates so that one set of driving blocks 322 corresponds to the abutment plate 42 of the telescopic mechanism 41. Then, the telescopic cylinder drives the abutment plate 42 to move closer to the abutment plate 42, so that the included angle formed by the two sets of connecting arms 323 increases, thereby increasing the size of the clamping cavity 311, so that the vial 100 is disengaged from the clamping cavity 311.

[0048] In some possible implementations, in order to effectively realize the sliding and guiding of the drive block 322 and the clamping body 31, a slider 3211 is provided on the side of the chassis 321 near the clamping body 31, and a groove 3211 is provided on each of the two sets of clamping bodies 31 to cooperate with the slider 3211; in order to effectively realize the sliding and guiding of the drive block 322 and the chassis 321, a slider 3212 is provided on the chassis 321, and a groove 3212 is provided on the drive block 322 to cooperate with the slider 3212.

[0049] In some possible implementations, an abutment block 325 is provided on the drive block 322 and is in transmission cooperation with the pick-and-place mechanism 4; the abutment block 325 is used to achieve sliding drive of the drive block 322 in transmission cooperation with the abutment plate 42.

[0050] In some possible implementations, in order to effectively dispense solution into vials 100, the dispensing mechanism 5 includes a support base 51 mounted on a base 1, a support frame 52 mounted on the support base 51, a needle holder 53 mounted on the support frame 52 and slidingly engaged with the support frame 52 in a vertical direction, a vertical lifting mechanism 54 mounted on the support frame 52 for controlling the vertical movement of the needle holder 53, a peristaltic pump 55 mounted on the support frame 52, a support rod 56 mounted on the support frame 52 and located above the support frame 52, and a dispensing needle used in conjunction with the peristaltic pump 55 and the needle holder 53.

[0051] The support rod 56 is used to suspend the dispensing bag at a high position; the dispensing needle includes a needle one inserted into the dispensing bag, a needle two mounted on the needle seat 53, and a dispensing tube connected to the needle one and needle two respectively and used in conjunction with the peristaltic pump 55; the vertical lifting mechanism 54 is used to control the lifting and lowering of the needle seat 53, so that the needle two can be inserted into vials 100 of different sizes. Specifically, the vertical lifting mechanism 54 is a cylinder; the liquid in the dispensing bag is transported to the vial 100 through the cooperation of the peristaltic pump 55 and the dispensing needle, and mixed with the powder in the vial 100; then the forward and reverse rotation of the turntable 2 is used to achieve mixing.

[0052] In some possible implementations, the turntable 2 is in two sets, and the liquid dispensing mechanism 5 is located between the two sets of turntable 2; the support base 51 and the support frame 52 are rotatably engaged in the horizontal direction.

[0053] By rotating the support base 51 and the support frame 52, both sets of turntables 2 can be used to dispense liquids into vials 100, thereby further improving work efficiency when dispensing large quantities of liquids.

[0054] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
