AI Technical Summary
In the current process of mixing anesthetic drugs, manual shaking makes it difficult to ensure the uniformity of the drug, resulting in inconsistent efficacy. In addition, the drug solution is prone to sticking to the wall and leaving residue, which affects the effect of use.
An anesthetic drug mixing device was designed, including a mixing cup, a piston head, a mixing hood, and an adjusting rod. The adjusting rod drives the mixing hood to move below the piston head, and the drug solution is mixed using a turbulence channel. After mixing, the mixing hood is kept in close contact with the bottom surface of the piston head to prevent residue. The device is kept sealed when the drug solution is drawn with a syringe.
This ensures thorough mixing of the medicinal solution, avoids residue adhering to the walls, and improves the consistency and effectiveness of the medicine.

Abstract
Claims
1. A device for mixing anesthetic drugs, characterized in that: The device includes a mixing cup (1), a piston head (2) which is slidably connected inside the mixing cup (1), a mixing cover (3) which is provided below the piston head (2), a connecting pipe (7) which is fixedly connected to the upper surface of the piston head (2), and a through hole communicating with the connecting pipe (7) is opened in the middle of the piston head (2). An adjusting rod (6) for switching the mixing cover (3) between a first state and a second state is sleeved inside the connecting pipe (7). In the first state, the mixing cover (3) is close to the bottom surface of the piston head (2). In the second state, the mixing cover (3) moves freely along its axis below the piston head (2). An air vent (5) is opened at the lower end of the mixing cup (1), and a plug (4) for inserting a syringe needle can be detachably installed in the air vent (5).
2. The anesthetic drug compounding device according to claim 1, wherein: The bottom surfaces of the mixing cup (1) and piston head (2) as well as the mixing cover (3) are all designed in an inverted cone shape and fit together. A rubber pad that abuts against the inner wall of the mixing cup (1) is provided on the circumferential surface of the piston head (2).
3. The anesthetic drug compounding device of claim 1, wherein: The surface of the mixing shroud (3) is provided with several uniformly distributed turbulence grooves (9), and the bottom surface of the piston head (2) is fixedly connected with several protrusions (8) that correspond one-to-one with the turbulence grooves (9).
4. The anesthetic drug compounding device of claim 1, wherein: The adjusting rod (6) includes a fixed rod (601) and a rotating rod (602). The fixed rod (601) and the rotating rod (602) have the same diameter and are both sleeved inside the connecting pipe (7). The rotating rod (602) is rotatably connected to the upper end of the fixed rod (601). The lower end of the fixed rod (601) is fixedly connected to the mixing cover (3). The lower end of the rotating rod (602) is provided with a thread (603), which is adapted to the upper thread of the connecting pipe (7). When the rotating rod (602) is threaded to the connecting pipe (7), the mixing cover (3) is in the first state.
5. The anesthetic drug compounding device according to claim 4, wherein: The lower end of the rotating rod (602) is fixedly connected to a T-shaped circular plate (604), and the upper end of the fixing rod (601) is provided with a T-shaped circular groove (605) that fits onto the T-shaped circular plate (604).
6. The anesthetic drug compounding apparatus as claimed in claim 4, wherein: Both sides of the fixed rod (601) are fixedly connected to limit sliders (606), and both sides of the inner wall of the connecting tube (7) are provided with limit grooves (607) that are adapted to slide with the limit sliders (606). The lower end of the fixed rod (601) is fixedly connected to a sealing ring (10) that is adapted to the through hole on the bottom surface of the piston head (2).
7. The anesthetic drug compounding apparatus as claimed in claim 1, wherein: The upper end of the plug (4) is threaded to the air outlet (5), and the outer side of the plug (4) is provided with a sealing ring that is compatible with the air outlet (5). A circular hole (12) is opened through the inside of the plug (4), and a rubber block (11) is fixedly connected in the circular hole (12). The upper side of the circular hole (12) is designed as an inverted cone.
