Description

Technical Field

[0001] This invention specifically relates to an anesthetic solution dilution device. Background Technology

[0002] Anesthesia is the use of drugs or other methods to temporarily eliminate sensation in a patient, either whole or in a specific area, to achieve pain relief. Before anesthesia is administered, an appropriate ratio of anesthetic solution must be prepared. The concentration of the solution directly affects the anesthetic effect; too high or too low a concentration can easily lead to medical safety accidents. Therefore, to achieve the ideal anesthetic effect without harming the patient's body, anesthesiologists must strictly follow regulations and requirements when preparing the solution.

[0003] Existing anesthetic solution dilution devices typically adjust the concentration of anesthetic solutions by adding an appropriate dose of anesthetic solution and diluent to a mixing tank at once, followed by stirring with a rotating shaft. However, this single-addition and stirring method in existing devices easily leads to uneven mixing, reducing the device's effectiveness in diluting anesthetic solutions. Furthermore, the lack of stirring during the addition process further reduces the device's overall efficiency. To address these technical problems, an anesthetic solution dilution device is proposed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention proposes an anesthetic solution dilution device that improves the effectiveness and efficiency of diluting anesthetic solutions.

[0005] An anesthetic fluid dilution device includes: a mounting frame and a dilution mechanism, the dilution mechanism comprising:

[0006] A mixing cylinder is mounted on the mounting bracket;

[0007] The liquid supply mechanism includes two sets of drug storage cylinders, two sets of piston cylinders, a first transmission assembly, and a dual-output motor. The two sets of drug storage cylinders and the two sets of piston cylinders are all mounted on the mounting frame. The bottom end of each piston cylinder is connected to the drug storage cylinder and the mixing cylinder respectively via a one-way inlet valve pipe and a one-way outlet valve pipe. A piston is installed inside each piston cylinder, and a piston rod is installed at the top end of each piston. The dual-output motor is mounted at the top of the mounting frame and is connected to the two sets of piston rods via the first transmission assembly. The first transmission assembly converts the rotation of the dual-output motor into the reciprocating up-and-down movement of the two sets of piston rods.

[0008] The stirring mechanism includes a stirring rod and a second transmission assembly. The stirring rod is disposed inside the mixing cylinder and is connected to the dual-output motor through the second transmission assembly. The second transmission assembly is used to convert the rotation of the dual-output motor into the reciprocating rotation and up-and-down movement of the stirring rod.

[0009] The beneficial effects of the above-mentioned anesthetic solution dilution device are as follows:

[0010] By placing appropriate doses of anesthetic solution and diluent into two sets of storage cylinders, and then starting the dual-output motor, the rotation of the dual-output motor drives two sets of piston rods to move up and down reciprocally via the first transmission component. This reciprocating motion of the two sets of pistons allows the anesthetic solution and diluent from the two storage cylinders to be quantitatively and sequentially fed into the mixing cylinder. Simultaneously, the rotation of the dual-output motor drives the stirring rod to rotate and move up and down via the second transmission component, thus stirring the anesthetic solution and diluent in the mixing cylinder. The quantitative and sequential addition of anesthetic solution and diluent, along with the stirring rod's reciprocating rotation and up-and-down movement, improves the device's anesthetic solution dilution effect. Furthermore, the addition and stirring of anesthetic solution and diluent can be performed simultaneously, increasing the device's efficiency in diluting anesthetic solution.

[0011] In one embodiment, the first transmission assembly includes a first turntable and a mounting rod. One output end of the dual-output motor is coaxially connected to the first turntable. A first deflector shaft is eccentrically mounted on the first turntable. Two sets of first guide shafts are oppositely arranged at the top of the mounting frame. The mounting rod is slidably sleeved on the two sets of first guide shafts. A first deflector groove is formed on the mounting rod, and the first deflector shaft slides through the first deflector groove. Two sets of piston rods are connected to both ends of the mounting rod. The dual-output motor drives the first turntable to rotate, which in turn drives the first deflector shaft to rotate. The rotation of the first deflector shaft, in conjunction with the first deflector groove, drives the mounting rod to slide up and down reciprocally. This reciprocating motion of the mounting rod drives the two sets of piston rods to slide up and down reciprocally. The piston rods, in turn, drive the pistons to slide up and down reciprocally. This reciprocating motion of the pistons allows for the sequential, quantitative addition of anesthetic fluid and diluent from the two sets of drug storage cylinders into the mixing cylinder, making the addition of anesthetic fluid and diluent into the mixing cylinder convenient.

[0012] In one embodiment, the first transmission assembly further includes a first driving member and a first guide block; the first guide block is slidably disposed on the first turntable along the radial direction of the first turntable, the first dial is disposed on the first guide block, the first driving member is rotatably disposed on the first turntable and connected to the first guide block, and rotating the first driving member can drive the first guide block to slide so that the first dial is eccentric or coaxial with the first turntable. The first guide block is driven to slide by rotating the first driving component. The sliding of the first guide block drives the first dial shaft to slide. The sliding of the first dial shaft can change the eccentricity of the first dial shaft. When the eccentricity of the first dial shaft increases, the rotation of the first dial shaft and its cooperation with the first dial groove can increase the stroke of the mounting rod sliding up and down, thereby increasing the stroke of the piston rod driving the piston to slide up and down, and thus increasing the amount of anesthetic and diluent added to the mixing cylinder at one time. Conversely, when the eccentricity of the first dial shaft decreases, the amount of anesthetic and diluent added to the mixing cylinder at one time can be reduced, which is convenient for adjustment according to needs. Moreover, when the first dial shaft is coaxial with the first turntable, the rotation of the first dial shaft does not drive the mounting rod to slide, which makes it convenient to continue stirring the anesthetic and diluent in the mixing cylinder when the addition of anesthetic and diluent is stopped, thus improving the practicality of the device.

[0013] In one embodiment, the first driving component includes a first screw; a first guide groove is formed at one end of the first turntable, a first guide block is slidably disposed within the first guide groove along the radial direction of the first turntable, and the first screw is rotatably disposed within the first guide groove and threadedly connected to the first guide block. By rotating the first screw in thread engagement with the first guide block, the first guide block can be driven to move, thereby increasing the eccentricity of the first dial shaft. By rotating the first screw in reverse in thread engagement with the first guide block, the first guide block can be driven to move, thereby decreasing the eccentricity of the first dial shaft. Stopping the rotation of the first screw fixes the first dial shaft, making the adjustment of the eccentricity of the first dial shaft convenient and effortless.

[0014] In one embodiment, a third transmission assembly is also included. Both ends of the mounting rod are connected to two sets of piston rods via the third transmission assembly. Adjusting the third transmission assembly adjusts the stroke of the piston rods as they reciprocate up and down. By adjusting the third transmission assembly to change the stroke of the piston rods, the amount of anesthetic and diluent added to the mixing cylinder at one time can be adjusted as needed, thus facilitating further adjustment of the anesthetic concentration in the mixing cylinder as required.

[0015] In one embodiment, the third transmission assembly includes a gear, a rack, a connecting rod, a second guide block, and a second driving member. Two sets of mounting seats are disposed opposite each other at the top of the mounting frame. The gear is rotatably mounted on the mounting seats. The rack is mounted on the top of each of the two sets of piston rods. The rack's top passes through the top of the mounting frame and meshes with the gear. The connecting rod is disposed around the gear. The second guide block is slidably mounted on the mounting rod along its length. A second deflector is disposed on the second guide block. A second deflector groove is formed on the connecting rod, and the second deflector slidably passes through the second deflector groove. The second driving member is rotatably mounted on the mounting rod and connected to the second guide block. Rotating the second driving member drives the second guide block to slide. The reciprocating movement of the mounting rod drives the second dial shaft to move downwards. This reciprocating movement of the second dial shaft, in conjunction with the second dial groove, drives the gear to rotate reciprocally. The gear's reciprocating rotation meshes with the rack, driving the rack to move up and down. When the concentration of the anesthetic solution in the mixing cylinder needs to be adjusted again, rotating the second drive component drives the second guide block, which in turn moves the second dial shaft. When the second dial shaft moves away from the gear, the mounting rod, driving the second dial shaft to move up and down, in conjunction with the second dial groove, reduces the angle of the gear's reciprocating rotation. This reduced angle, combined with the meshing of the rack, reduces the rack's stroke, thus reducing the piston rod's stroke driving the piston's reciprocating sliding motion. This, in turn, reduces the amount of anesthetic solution or diluent added to the mixing cylinder at a time. Conversely, when the second dial shaft moves closer to the gear, the amount of anesthetic solution or diluent added to the mixing cylinder at a time increases, facilitating separate adjustment of the amount of anesthetic solution and diluent added to the mixing cylinder, and allowing for further adjustment of the anesthetic solution concentration as needed.

[0016] In one embodiment, the second driving component includes a second screw; both ends of the mounting rod are provided with second guide grooves, the second guide block is slidably disposed in the second guide groove, and the second screw is rotatably disposed in the second guide groove and threadedly connected to the second guide block. By rotating the second screw and engaging the threaded connection with the second guide block, the second guide block can be driven to move the second shift shaft away from the gear; by rotating the second screw and engaging the threaded connection with the second guide block in the opposite direction, the second guide block can be driven to move the second shift shaft closer to the gear, and stopping the rotation of the second screw can fix the second shift shaft, making it easy to adjust the position of the second shift shaft.

[0017] In one embodiment, the second transmission assembly includes a second turntable, a guide rod, a connecting shaft, and a rotating shaft; one output end of the dual-output motor is coaxially connected to the second turntable, a third deflector is eccentrically arranged on the second turntable, two sets of second guide shafts are arranged opposite each other at the top of the mounting bracket, the guide rod is slidably sleeved on the two sets of second guide shafts, a third deflector groove is opened on the guide rod, the third deflector is slidably arranged in the third deflector groove, the bottom end of the guide rod is connected to the connecting shaft, the bottom end of the connecting shaft passes through the top of the mounting bracket and is rotatably connected to the rotating shaft, a through hole is opened at the top of the mixing cylinder, the rotating shaft passes through the through hole and is connected to the stirring rod, a spiral guide groove is opened on the circumference of the rotating shaft, a spiral guide block is provided on the inner wall of the through hole, and the spiral guide groove is slidably sleeved on the spiral guide block. When the dual-output motor rotates, driving the first turntable to add anesthetic and diluent into the mixing cylinder, the dual-output motor simultaneously drives the second turntable to rotate. The rotation of the second turntable drives the third dial shaft to rotate. The rotation of the third dial shaft, in conjunction with the third dial groove, drives the guide rod to move up and down reciprocally. The reciprocating movement of the guide rod drives the connecting shaft to move up and down reciprocally. The reciprocating movement of the connecting shaft drives the rotating shaft to move up and down reciprocally. This causes the rotating shaft to drive the stirring rod to move up and down reciprocally. The reciprocating movement of the rotating shaft, through the cooperation of the spiral guide block and the spiral guide groove, causes the rotating shaft to rotate reciprocally. The reciprocating rotation of the rotating shaft drives the stirring rod to rotate reciprocally. By stirring the anesthetic and diluent in the mixing cylinder during the addition of anesthetic and diluent, the efficiency of diluting the anesthetic in the device is improved. Furthermore, the reciprocating rotation and up and down movement of the stirring rod improve the mixing effect of the stirring rod on the anesthetic and diluent in the mixing cylinder, making it easier for the anesthetic and diluent to mix evenly, thereby improving the effect of the device in diluting the anesthetic.

[0018] In one embodiment, a fixing ring groove is provided at the bottom end of the connecting shaft, and a fixing ring is provided at the top end of the rotating shaft. The fixing ring is rotatably disposed in the fixing ring groove.

[0019] In one embodiment, the mixing cylinder has graduated grooves on its circumference to facilitate observation of the amount of diluted anesthetic solution within the mixing cylinder. Attached Figure Description

[0035] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0036] Please see Figure 1 One embodiment of an anesthetic fluid dilution device includes a mounting frame 10 and a dilution mechanism, the dilution mechanism including a mixing cylinder 20, a fluid supply mechanism and a stirring mechanism 60.

[0037] The mixing cylinder 20 is mounted on the mounting frame 10. Specifically, the mixing cylinder 20 has graduated grooves 202 on its circumference. These grooves facilitate observation of the amount of diluted anesthetic solution within the mixing cylinder 20. Furthermore, the bottom of the mixing cylinder 20 has a conical structure and a drain port 203 with a valve, facilitating the discharge of the diluted anesthetic solution from the mixing cylinder 20.

[0038] Please see Figures 1 to 4 In one embodiment, the liquid supply mechanism includes two sets of drug storage cylinders 30, two sets of piston cylinders 301, a first transmission assembly, and a dual-output motor 302. The two sets of drug storage cylinders 30 and the two sets of piston cylinders 301 are all mounted on the mounting frame 10. The bottom end of the piston cylinder 301 is connected to the drug storage cylinder 30 and the mixing cylinder 20 respectively through a one-way liquid inlet valve pipe 303 and a one-way liquid outlet valve pipe 304. A piston 305 is provided inside the piston cylinder 301, and a piston rod 306 is provided at the top of the piston 305. The dual-output motor 302 is located at the top of the mounting frame 10 and is connected to the two sets of piston rods 306 through the first transmission assembly. The first transmission assembly is used to convert the rotation of the dual-output motor 302 into the up-and-down reciprocating movement of the two sets of piston rods 306.

[0039] Specifically, the first transmission assembly includes a first turntable 40 and a mounting rod 401; one output end of the dual-output motor 302 is coaxially connected to the first turntable 40, a first deflector shaft 402 is eccentrically arranged on the first turntable 40, two sets of first guide shafts 101 are arranged opposite each other at the top of the mounting bracket 10, the mounting rod 401 is slidably sleeved on the two sets of first guide shafts 101, a first deflector groove 4011 is opened on the mounting rod 401, the first deflector shaft 402 slides through the first deflector groove 4011, and two sets of piston rods 306 are connected to both ends of the mounting rod 401.

[0040] In the above embodiment, the rotation of the dual-output motor 302 drives the first turntable 40 to rotate, and the rotation of the first turntable 40 drives the first dial shaft 402 to rotate. The rotation of the first dial shaft 402, in conjunction with the first dial groove 4011, drives the mounting rod 401 to slide up and down repeatedly. The up and down sliding of the mounting rod 401 drives the two sets of piston rods 306 to slide up and down repeatedly. The up and down sliding of the piston rods 306 drives the piston 305 to slide up and down repeatedly. When the piston 305 slides upward, a negative pressure is generated in the piston cylinder 301. At this time, the anesthetic fluid and diluent in the drug storage cylinder 30 can be drawn into the piston cylinder 301 through the one-way liquid inlet valve pipe 303. When the piston 305 slides downward, the anesthetic fluid and diluent in the piston cylinder 301 can be transported into the mixing cylinder 20 through the one-way liquid outlet valve pipe 304. By repeating this process, the anesthetic fluid and diluent in the two sets of drug storage cylinders 30 can be quantitatively and sequentially added into the mixing cylinder 20.

[0041] Please refer to the following: Figure 7 The stirring mechanism 60 includes a stirring rod 601 and a second transmission assembly. The stirring rod 601 is disposed inside the mixing cylinder 20 and is connected to a dual-output motor 302 through the second transmission assembly. The second transmission assembly is used to convert the rotation of the dual-output motor 302 into the reciprocating rotation and up-and-down movement of the stirring rod 601.

[0042] Specifically, the second transmission assembly includes a second turntable 604, a guide rod 606, a connecting shaft 603, and a rotating shaft 602; one output end of the dual-output motor 302 is coaxially connected to the second turntable 604, and a third deflector 605 is eccentrically mounted on the second turntable 604. Two sets of second guide shafts 103 are oppositely mounted on the top of the mounting bracket 10, and the guide rod 606 is slidably sleeved on the two sets of second guide shafts 103. A third deflector groove 6061 is provided on the guide rod 606, and the third deflector 605 can slide. The mixing cylinder 20 is housed within the third groove 6061. A connecting shaft 603 is connected to the bottom end of the guide rod 606. The bottom end of the connecting shaft 603 passes through the top of the mounting bracket 10 and is rotatably connected to a rotating shaft 602. A through hole 201 is provided at the top of the mixing cylinder 20. The rotating shaft 602 passes through the through hole 201 and is connected to the stirring rod 601. A spiral guide groove 6021 is provided around the rotating shaft 602. A spiral guide block 2011 is provided on the inner wall of the through hole 201, and the spiral guide groove 6021 is slidably fitted onto the spiral guide block 2011. A fixing ring groove 6031 is provided at the bottom end of the connecting shaft 603, and a fixing ring 6022 is provided at the top end of the rotating shaft 602. The fixing ring 6022 is rotatably positioned within the fixing ring groove 6031.

[0043] In the above embodiment, when the dual-output motor 302 rotates to drive the first turntable 40 to rotate and quantitatively add the anesthetic fluid and diluent from the two sets of drug storage cylinders 30 into the mixing cylinder 20, the dual-output motor 302 simultaneously drives the second turntable 604 to rotate. The rotation of the second turntable 604 drives the third actuating shaft 605 to rotate. The rotation of the third actuating shaft 605, in conjunction with the third actuating groove 6061, drives the guide rod 606 to move up and down reciprocally. The up and down reciprocating movement of the guide rod 606 drives the connecting shaft 603 to move up and down reciprocally. The up and down reciprocating movement of the connecting shaft 603 drives the rotating shaft 602 to move up and down reciprocally, thereby causing the rotating shaft 602 to drive the stirring rod 60. The rotating shaft 602 moves up and down reciprocally. The reciprocating movement of the rotating shaft 602 is achieved through the cooperation of the spiral guide block 2011 and the spiral guide groove 6021. The reciprocating rotation of the rotating shaft 602 drives the stirring rod 601 to rotate reciprocally. By quantitatively and sequentially adding the anesthetic solution and diluent into the mixing cylinder 20, and through the reciprocating rotation and up and down movement of the stirring rod 601, the mixing effect of the stirring rod 601 on the anesthetic solution and diluent in the mixing cylinder 20 is improved. This facilitates a more uniform mixing of the anesthetic solution and diluent, improves the dilution effect of the device, and the addition and stirring of the anesthetic solution and diluent can be carried out simultaneously, improving the efficiency of the device in diluting the anesthetic solution.

[0044] Please participate Figures 3 to 5 In one embodiment, the first transmission assembly further includes a first driving member and a first guide block 403; the first guide block 403 is slidably disposed on the first turntable 40 along the first turntable 40 radially, the first dial shaft 402 is disposed on the first guide block 403, the first driving member is rotatably disposed on the first turntable 40 and connected to the first guide block 403, rotating the first driving member can drive the first guide block 403 to slide, so that the first dial shaft 402 is eccentric or coaxial with the first turntable 40.

[0045] Specifically, the first driving component includes a first screw 404; a first guide groove 405 is provided at one end of the first turntable 40; a first guide block 403 is slidably disposed in the first guide groove 405 along the radial direction of the first turntable 40; and the first screw 404 is rotatably disposed in the first guide groove 405 and threadedly connected to the first guide block 403.

[0046] In the above embodiments, when it is necessary to simultaneously adjust the amount of anesthetic fluid and diluent added to the mixing cylinder 20 at one time, by rotating the first screw 404 and threadedly engaging the first guide block 403, the first guide block 403 is driven to slide, increasing the eccentricity of the first dial 402. The first turntable 40 then drives the first dial 402 to rotate, engaging with the first dial groove 4011, which increases the stroke of the mounting rod 401 as it slides up and down. This increases the stroke of the piston rod 306 driving the piston 305 as it slides up and down, thereby increasing the amount of anesthetic fluid and diluent added to the mixing cylinder 20 at one time. Conversely, by rotating the first screw 404 and threadedly engaging the first guide block 403 in the opposite direction, the first guide block 403 is driven to slide, decreasing the eccentricity of the first dial 402. The first turntable 40 then drives the first dial 402 to slide in the opposite direction. The rotation of 402, in conjunction with the first groove 4011, reduces the stroke of the mounting rod 401 sliding up and down, thereby reducing the stroke of the piston rod 306 driving the piston 305 to slide up and down. This, in turn, reduces the amount of anesthetic and diluent added to the mixing cylinder 20 at a time, making it easier to adjust the amount of anesthetic and diluent added to the mixing cylinder 20 at a time. Furthermore, when the first guide block 403 drives the first dial 402 to slide, making the first dial 402 coaxial with the first turntable 40, the rotation of the first turntable 40 causes the first dial 402 to rotate coaxially. At this time, the first dial 402 does not drive the mounting rod 401 to slide up and down, thus stopping the movement of the mounting rod 401, piston rod 306, and piston 305. This facilitates the continued stirring of the anesthetic and diluent in the mixing cylinder 20 even when the addition of anesthetic and diluent has stopped, improving the practicality of the device.

[0047] Please see Figures 3 to 6 In one embodiment, a third transmission assembly 50 is also included. Both ends of the mounting rod 401 are connected to two sets of piston rods 306 through the third transmission assembly 50. Adjusting the third transmission assembly 50 can adjust the stroke of the mounting rod 401 driving the piston rods 306 to move up and down reciprocally.

[0048] Specifically, the third transmission component 50 includes a gear 501, a rack 502, a connecting rod 503, a second guide block 505, and a second driving member. Two sets of mounting seats 102 are arranged opposite each other at the top of the mounting frame 10. The gear 501 is rotatably mounted on the mounting seat 102. A rack 502 is provided at the top of each of the two sets of piston rods 306. The top of the rack 502 passes through the top of the mounting frame 10 and meshes with the gear 501. A connecting rod 503 is provided around the gear 501. The second guide block 505 is slidably mounted on the mounting rod 401 along its length. A second deflector 504 is provided on the second guide block 505. A second deflector groove 5031 is provided on the connecting rod 503. The second deflector 504 slidably passes through the second deflector groove 5031. The second driving member is rotatably mounted on the mounting rod 401 and connected to the second guide block 505. Rotating the second driving member drives the second guide block 505 to slide.

[0049] The second driving component includes a second screw 506; the mounting rod 401 has a second guide groove 4012 at both ends, the second guide block 505 is slidably disposed in the second guide groove 4012, the second screw 506 is rotatably disposed in the second guide groove 4012 and is threadedly connected to the second guide block 505.

[0050] In the above embodiments, when it is necessary to adjust the amount of anesthetic solution and diluent added to the mixing cylinder 20 at one time, the second screw 506 is rotated and threadedly engaged with the second guide block 505, driving the second guide block 505 to move the second dial shaft 504 away from the gear 501. At this time, the mounting rod 401 drives the second dial shaft 504 to move up and down reciprocally, engaging with the second dial groove 5031, which reduces the angle of reciprocating rotation of the gear 501. The reduced angle of reciprocating rotation of the gear 501, when meshing with the rack 502, reduces the stroke of the rack 502 moving up and down reciprocally, thereby reducing the stroke of the piston rod 306 driving the piston 305 to slide up and down reciprocally, and thus reducing the amount of anesthetic solution or diluent added to the mixing cylinder 20 at one time. Conversely, by rotating the second screw 506 in the opposite direction... The second guide block 505 is threaded together with the second guide block 505, which drives the second gear shaft 504 to move closer to the gear 501. At this time, the mounting rod 401 drives the second gear shaft 504 to move up and down reciprocally, which cooperates with the second gear groove 5031 to increase the angle of reciprocating rotation of the gear 501. The increased angle of reciprocating rotation of the gear 501 and its meshing with the rack 502 increases the stroke of the rack 502 to move up and down reciprocally, thereby increasing the stroke of the piston rod 306 driving the piston 305 to slide up and down reciprocally. This increases the amount of anesthetic or diluent added to the mixing cylinder 20 at one time. It is convenient to adjust the amount of anesthetic and diluent added to the mixing cylinder 20 at one time, and it is easy to readjust the concentration of anesthetic in the mixing cylinder 20 as needed, thus improving the practicality of the device.

[0051] The specific implementation of the above-mentioned anesthetic fluid dilution device is as follows:

[0052] First, appropriate doses of anesthetic solution and diluent are placed into two sets of drug storage cylinders 30, respectively. Then, the dual-output motor 302 is started to rotate, driving the first turntable 40 to rotate. The rotation of the first turntable 40 drives the first dial shaft 402 to rotate. The rotation of the first dial shaft 402, in conjunction with the first dial groove 4011, drives the mounting rod 401 to slide up and down reciprocally. The up and down reciprocating movement of the mounting rod 401 drives the two sets of piston rods 306 to slide up and down reciprocally. The up and down reciprocating movement of the piston rods 306 drives the piston 305 to slide up and down reciprocally. When piston 305 slides upward, a negative pressure is generated inside piston cylinder 301. At this time, the anesthetic fluid and diluent in the drug storage cylinder 30 can be drawn into piston cylinder 301 through one-way inlet valve pipe 303. When piston 305 slides downward, the anesthetic fluid and diluent in piston cylinder 301 can be delivered into mixing cylinder 20 through one-way outlet valve pipe 304. This process is repeated to quantitatively add the anesthetic fluid and diluent from the two sets of drug storage cylinders 30 into mixing cylinder 20. At the same time, dual-output motor 302 synchronously drives the second... The rotation of the second turntable 604 drives the rotation of the third rotary shaft 605. The rotation of the third rotary shaft 605, in conjunction with the third rotary groove 6061, drives the guide rod 606 to move up and down reciprocally. The up and down reciprocating movement of the guide rod 606 drives the connecting shaft 603 to move up and down reciprocally. The up and down reciprocating movement of the connecting shaft 603 drives the rotating shaft 602 to move up and down reciprocally. This causes the rotating shaft 602 to drive the stirring rod 601 to move up and down reciprocally. The up and down reciprocating movement of the rotating shaft 602 is transmitted through the spiral guide block 2011 and the spiral guide groove. The 6021 mechanism causes the rotating shaft 602 to reciprocate, which in turn drives the stirring rod 601 to reciprocate. By quantitatively and sequentially adding the anesthetic solution and diluent into the mixing cylinder 20, and by the reciprocating rotation and up-and-down movement of the stirring rod 601, the mixing effect of the stirring rod 601 on the anesthetic solution and diluent in the mixing cylinder 20 is improved. This facilitates a more uniform mixing of the anesthetic solution and diluent, improves the dilution effect of the device, and allows the addition and stirring of the anesthetic solution and diluent to be carried out simultaneously, thereby improving the efficiency of the device in diluting the anesthetic solution.

[0053] By rotating the first screw 404 and engaging the first guide block 403 in a threaded connection, the first guide block 403 drives the first dial 402 to slide and adjust the eccentricity of the first dial 402. This allows for simultaneous adjustment of the amount of anesthetic and diluent added to the mixing cylinder 20 at a time, as needed. When the first dial 402 is coaxial with the first turntable 40, the rotation of the first turntable 40 causes the first dial 402 to rotate coaxially. At this time, the first dial 402 does not drive the mounting rod 401 to slide up and down, thereby stopping the movement of the mounting rod 401, piston rod 306, and piston 305. This facilitates continued stirring of the anesthetic and diluent in the mixing cylinder 20 even when the addition of anesthetic and diluent has stopped, improving the practicality of the device.

[0054] By rotating the second screw 506 and engaging the second guide block 505 in a threaded connection, the second guide block 505 is driven to move the second dial 504 away from or towards the gear 501. This allows for the adjustment of the amount of anesthetic solution and diluent added to the mixing cylinder 20 at one time, as needed. It also facilitates the readjustment of the concentration of the anesthetic solution in the mixing cylinder 20 as needed, thus improving the practicality of the device.
