[0011] Furthermore, the bottom of the piston rod extends to below the fixed plate, and a plurality of grooves are arranged on the surface of the turntable. The plurality of grooves are arranged in two groups, and the two groups of grooves are symmetrically arranged with the turntable as the center.

[0015] Furthermore, a method for preparing a dexamethasone palmitic acid lipid comprises the following steps:

[0016] S1: After injecting dexamethasone palmitate into the mixing bottle, twist the positioning ring to rotate to the outer end of the sliding hole frame, place the mixing bottle inside the sliding hole frame so that it contacts the top of the disc, pull the elastic rod and push the positioning ring to rotate above the mixing bottle, and the rubber ring contacts the surface of the mixing bottle using the elasticity of the elastic rod and squeezes it;

[0017] S2: When the bottom of the mixing bottle contacts the top of the disc, it squeezes the pressure plate to move toward the surface of the curved plate.

The rubber ring contacts and squeezes the surface of the mixing bottle by the elasticity of the elastic rod, thereby improving the stability of the mixing bottle when shaking up and down. When the bottom of the mixing bottle contacts the top of the disc, the pressure plate is squeezed to move toward the surface of the bent plate. The rubber rod at the bottom of the pressure plate squeezes the mixing bottle by the elasticity of the spring sheet and the elastic sheet, thereby improving the stability of the mixing bottle when mixing dexamethasone palmitate, so that the mixing bottle can move up and down synchronously with the disc, thereby preventing the disc from separating from the mixing bottle when moving, causing the disc to collide with the dexamethasone palmitate and cause the mixing bottle to break.

[0022] The present invention starts a motor to drive the turntable to rotate inside an outer shell. When the turntable rotates, the piston rod pushes the stabilizing rod to rotate on the inner wall of the outer shell. The stabilizing rod and the motor are used to limit the turntable, thereby improving the stability of the turntable when it rotates. When the turntable rotates, the piston rod is pushed to move up and down. When the piston rod moves up and down, the disc is pushed to shake up and down inside the sliding hole frame through the hinge frame. When the disc shakes upward, it drives the mixing bottle to move up and down to mix the dexamethasone palmitate inside the mixing bottle, thereby improving the convenience of the dexamethasone palmitate when being mixed and prepared, and avoiding the situation that medical staff manually mix the dexamethasone palmitate and cause uneven mixing.

[0023] When the turntable of the present invention rotates, the grooves on the surface will contact the surface of the cylindrical contact rod, and will be separated from the cylindrical contact rod by rotation and squeeze the arc spring plate to produce deformation. The reciprocating contact and separation of the grooves with the cylindrical contact rod will generate vibration, and the vibration will be transmitted to the disk through the piston rod, so that the vibration can oscillate the dexamethasone palmitate in the mixing bottle, thereby further improving the mixing efficiency of the dexamethasone palmitate.

When the turntable 41 rotates, it pushes the stabilizing rod 42 in the housing 1 through the piston rod 40. The inner wall of the rotating disk 41 is rotated, and the stabilizing rod 42 and the motor 45 are used to limit the rotating disk 41, so as to improve the stability of the rotating disk 41 during rotation. When the rotating disk 41 rotates, the piston rod 40 is pushed to move up and down. When the piston rod 40 moves up and down, it pushes the disc 12 to shake up and down inside the sliding hole rack 11 through the hinge frame 44. When the disc 12 shakes upward, it drives the mixing bottle to move up and down to mix the dexamethasone palmitic acid inside it, thereby improving the convenience of the mixing preparation of the dexamethasone palmitic acid and avoiding the medical staff Manual mixing of dexamethasone palmitate may result in uneven mixing.
