Generally speaking, intravenous anesthetics are more widely used. This type of anesthetic is fast induction, has no irritation to the respiratory tract, and no environmental pollution. Common types include thiopental, ketamine, etomidate, sodium oxybate, propofol, etc. The dosage of this type of anesthetic needs to be strictly controlled when injected.

After adjustment, the baffle is opened, and the drug in the liquid storage tank is transported to the infusion tank until the drug in the infusion tank overflows the baffle position, and then the baffle is closed, and the motor is controlled to rotate counterclockwise. The motor rotation speed is controlled according to the speed required for infusion, and the motor drives the driving gear, the driven gear, the screw, and the piston plate to move in sequence, thereby inputting the anesthetic drug from the liquid outlet to the anesthetic drug infusion tube into the patient's body. Of course, it can also be designed that the motor rotates counterclockwise to adjust the volume of the infusion tank and rotates clockwise to input the anesthetic drug into the patient. This design only needs to control the rotation of the motor and adjust its speed and direction to control the input amount and input speed of the anesthetic drug, which is efficient and fast.

Two support plates 8 are fixedly provided on the side wall of the liquid storage tank 1 near the hinge point 121, one of the support plates 8 is fixedly connected to the limiting cylinder 81, and the limiting block 82 is slidably connected inside the limiting cylinder 81. A spring 83 is provided between the limiting block 82 and the limiting cylinder 81, and the limiting block 82 is fixedly connected to the limiting rod 84 away from the spring 83. The diameter of the limiting rod 84 is smaller than the diameter of the limiting block 82; the second support leg 12 is provided with a cylindrical through hole 123 and a strip-shaped notch 124 that are interconnected. The inner diameter of the cylindrical through hole 123 is equal to the inner diameter of the limiting block 82, and the width of the strip-shaped notch 124 is greater than the diameter of the limiting rod 84 and smaller than the diameter of the cylindrical through hole 123. After the limiting rod 84 passes through the other support plate 8, it is fixedly connected to the pressure plate 85. When the device needs to be hung, the second leg 12 is rotated upward so that the hanging ring 122 faces upward, and the hanging ring 122 is hung on the corresponding hook; when the device needs to be placed on the desktop, the second leg 12 is rotated downward, and at the same time, one hand presses the pressure plate 85, and the limit rod 84 is used to press the limit block 82 into the limit cylinder 81. At this time, the limit rod 84 can pass through the strip notch 124 on the second leg 12 until the cylindrical through-hole 123, and then the pressure plate 85 is released. The limit block 82 passes into the cylindrical through-hole 123 under the resetting action of the spring 83, fixing the second leg 12. At this time, the hanging ring 122 contacts the ground, and the two first legs 11 and the third leg form a stable triangular structure, which stably supports the entire device on the desktop. This design is smart and convenient, and the placement of the device can be flexibly changed according to actual conditions. It is very practical.

[0040] The top of the liquid storage tank 1 is provided with a filling port 13, which is detachably connected to a cover 14. The bottom of the liquid storage tank 1 is connected to the infusion tank 2. A first through hole 5 is provided between the liquid storage tank 1 and the infusion tank 2. The bottom plate of the liquid storage tank 1 is an inclined structure that is retracted into the first through hole 5. The inclined bottom plate ensures that the anesthetic drug can be fully used without any residue. The infusion tank 2 has a V-shaped structure and is provided with a liquid outlet 21, which is located away from the drug dosage adjustment structure 3. The liquid outlet 21 is equipped with a valve 22. The liquid outlet 21 is connected to the lowest point of the infusion tank 2. The V-shaped structure of the infusion tank 2 ensures that the anesthetic drug is fully delivered to the patient and avoids any residue. It also helps to concentrate the liquid in the infusion tank 2 at the liquid outlet 21 for output. The side wall of the liquid storage tank 1 is provided with a first transparent observation window 15, which allows the anesthetic drug reserve in the liquid storage tank 1 to be observed, facilitating timely addition.

A retaining groove 16 is provided on the top of the infusion tank 2 for the sliding movement of the baffle 6 and connecting plate 61. A telescopic rod 7 is embedded in the bottom of the liquid storage tank 1, adjacent to the retaining groove 16, and the connecting plate 61 is fixed to the telescopic end of the telescopic rod 7. The telescopic rod 7 sequentially drives the connecting plate 61 and the baffle 6 to move, thereby separating the liquid storage tank 1 and the infusion tank 2 in a timely manner after the infusion tank 2 is filled with anesthetic drugs.

[0041] The infusion tank 2 is provided with a drug dosage adjustment structure 3 and a drug dosage prompt structure 4; the drug dosage adjustment structure 3 includes a piston plate 31, which follows the shape of the infusion tank 2 and is slidably connected to the infusion tank 2.

The second through hole 33 is rotatably connected to a coaxial driven gear 34. The screw 32 is threadedly connected to the driven gear 34. The driven gear 34 is meshed with a driving gear 35. The driving gear 35 is axially connected to a motor 36, and the motor 36 is embedded in the top of the infusion tank 2. After calculating the input amount and input speed of the anesthetic drug, the motor 36 can be controlled to rotate clockwise first, and then the driving gear 35, the driven gear 34, the screw 32, and the piston plate 31 can be driven to move in sequence, thereby adjusting the volume of the infusion tank 2. After adjustment, the baffle 6 is opened, and the drug in the liquid storage tank 1 is transported to the infusion tank 2 until the drug in the infusion tank 2 overflows the position of the baffle 6, and then the baffle 6 is closed, and the motor 36 is controlled to rotate counterclockwise, and the rotation speed of the motor 36 is controlled according to the speed required for infusion. The motor 36 drives the driving gear 35, the driven gear 34, the screw 32, and the piston plate 31 to move in sequence, thereby inputting the anesthetic drug from the liquid outlet 21 to the anesthetic drug infusion tube into the patient's body. Of course, it can also be designed that the motor 36 rotates counterclockwise to adjust the volume of the infusion tank 2 and rotates clockwise to input the anesthetic drug into the patient. This design only needs to control the rotation of the motor 36 and adjust its speed and direction to control the input amount and input speed of the anesthetic drug, which is efficient and fast.

[0042] The dosage reminder structure 4 includes an induction electrode sheet 41 near the liquid outlet 21 and an alarm 42 fixed to the top of the infusion tank 2 and electrically connected to the induction electrode sheet 41. When the anesthetic liquid is lower than the induction motor 36, the alarm 42 sounds, notifying the doctor that the anesthetic is about to be delivered.

[0043] A second transparent observation window 37 is provided on the side wall of the infusion tank 2, and a scale line is provided on the second transparent observation window 37. A calibration line 38 is provided on the side wall of the piston plate 31. The calibration line 38 and the scale line on the piston plate 31 can be used to observe the amount of liquid added and the remaining amount in the infusion tank 2.

[0044] Working principle: Before anesthesia, first connect the anesthesia infusion tube to the liquid outlet 21, open the cover 14, add the anesthetic into the liquid storage tank 1, and place the entire infusion device next to the operating table. Then, calculate the required anesthetic input amount and input speed according to the needs of the operation, and then start the drug dosage adjustment structure 3 to adjust the volume of the infusion tank 2. After adjustment, add the anesthetic in the liquid storage tank 1 into the infusion tank 2, and then inject the anesthetic. When the anesthetic is about to be injected, the drug dosage prompt structure 4 will prompt, and the doctor will confirm whether to continue adding the drug.
