Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a robotic arm-based automatic liquid injection device. Background Technology

[0002] Currently, in clinical applications, there are two main methods for disinfecting the internal tubing of anesthesia machines and ventilators: one is to manually add disinfectant solution, injecting it after each disinfection; the other is to place a whole bottle of disinfectant solution in the disinfection equipment and use an automatic dispensing system. Both methods have certain drawbacks: firstly, they require manual intervention, which is less environmentally friendly and carries some risk; secondly, the amount of disinfectant solution injected can be inaccurate; and thirdly, with automatic dispensing, if the disinfection interval is long, the purity of the disinfectant solution can easily decrease or it may expire, thus affecting the disinfection effect.

[0003] Therefore, we propose a robotic arm-based automated liquid injection device. Utility Model Content

[0004] The purpose of this invention is to provide a robotic arm-based automatic liquid injection device that optimizes pipeline disinfection operations, improves work efficiency and disinfection effect, and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a robotic arm-based automatic liquid dispensing device, comprising a base plate, a rotary motor mounted at the bottom of the base plate, an output shaft of the rotary motor passing through the base plate and connected to a concave turntable, the concave turntable rotating under the drive of the rotary motor, a basket mounted on the concave turntable, multiple vials being held inside the basket, a sliding fixing plate connected to the side of the base plate, a vertical slide rail mounted on the sliding fixing plate, a slider mounted inside the slide rail, the slider being able to move up and down along the slide rail, a lead screw fixing plate mounted on the slider, a lifting stepper motor mounted on the upper part of the lead screw fixing plate, the lifting lead screw of the lifting stepper motor being connected to the top of the lead screw fixing plate, a liquid-collecting needle fixing ring mounted on the bottom side of the lead screw fixing plate, a liquid-collecting needle mounted inside the liquid-collecting needle fixing ring, the liquid-collecting needle moving up and down under the drive of the lifting stepper motor, the liquid-collecting needle being able to extend into the vial.

[0006] Preferably, a signal sensing plate is installed on the edge of the concave turntable, and a metal contactor is installed on the base plate. The signal sensing plate can trigger the metal contactor during rotation.

[0007] Preferably, a lowering limit switch is installed on the sliding fixed plate, which can limit the descent of the lifting stepper motor.

[0008] Preferably, a lifting motor base is installed at the bottom of the lifting stepper motor, and a lifting limit switch is provided on the lifting motor base, which can limit the lifting stepper motor from rising.

[0009] Preferably, a vial limiting plate is installed on the sliding fixing plate, and a round hole is opened on the vial limiting plate, through which the liquid-taking needle can pass.

[0010] Preferably, a capillary support is installed on the side of the lead screw fixing plate, and an adapter is installed on the capillary support, one end of which is connected to the liquid collection needle tubing.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The vial containing the liquid medicine is placed on a flower basket and then on a concave turntable. The MCU main control drives a rotary motor to rotate the concave turntable on the base plate. When the signal sensor aligns with the metal contactor, the signal sensor triggers the metal contactor, and the rotary motor stops working, thus determining the position of the first vial. Then, a lifting stepper motor drives a lifting screw downwards, causing the retrieval needle mounted on the screw fixing plate to pierce into the vial until the lowering limit switch is triggered, at which point the lifting stepper motor stops descending. After retrieving the first vial, the MCU main control... When the lifting stepper motor drives the lifting screw to rotate upward, the dispensing needle rises and leaves the vial. Once the upper limit switch is triggered, the lifting stepper motor stops rising. The MCU main control then drives the rotary motor to continue rotating at a fixed angle to determine the position of the second vial. The lifting stepper motor is then driven again to rotate the lifting screw downward, causing the dispensing needle to move downward until the lower limit switch is triggered and stops. This achieves automated quantitative dispensing, optimizes pipeline disinfection operations, improves the accuracy of disinfectant injection, and the use of multiple vials prevents the disinfectant from becoming less pure or expired, thus improving work efficiency and disinfection effectiveness.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0018] Please see Figure 1-3This utility model includes a base plate 1, on the bottom of which a rotary motor 2 is mounted. The output shaft of the rotary motor 2 passes through the base plate 1 and is connected to a concave turntable 3. The concave turntable 3 rotates under the drive of the rotary motor 2. A flower basket 4 is mounted on the concave turntable 3, and multiple vials 5 are held inside the flower basket 4. A sliding fixing plate 6 is connected to the side of the base plate 1, and a vertical slide rail 7 is mounted on the sliding fixing plate 6. A slider 8 is mounted inside the slide rail 7, and the slider 8 can move along... The slide rail 7 moves up and down. A lead screw fixing plate 9 is installed on the slider 8. A lifting stepper motor 10 is installed on the upper part of the lead screw fixing plate 9. The lifting lead screw 11 of the lifting stepper motor 10 is connected to the top of the lead screw fixing plate 9. A liquid collection needle fixing ring 12 is installed on the bottom side of the lead screw fixing plate 9. A liquid collection needle 13 is installed inside the liquid collection needle fixing ring 12. The liquid collection needle 13 moves up and down under the drive of the lifting stepper motor 10. The liquid collection needle 13 can extend into the vial 5.

[0019] The edge of the concave turntable 3 is provided with a signal sensing plate 14, and the base plate 1 is provided with a metal contactor 15. The signal sensing plate 14 can trigger the metal contactor 15 during rotation.

[0020] Specifically, in this embodiment, the vial 5 is secured to the flower basket 4. The flower basket 4 is circular with multiple evenly spaced circular holes along its edge. A turntable fixing seat 22 is installed in each circular hole. The base of the turntable fixing seat 22 is circular and slightly smaller than the diameter of the circular hole in the flower basket 4. The base of the turntable fixing seat 22 has a bottom post. The vial 5 is secured to the turntable fixing seat 22. The flower basket 4 containing the vial 5 is placed on the concave turntable 3. The signal sensing plate 14 is installed at the bottom edge of the concave turntable 3. The MCU main controller drives the rotary motor 2 to rotate the concave turntable 3 on the base plate 1. When the signal sensing plate 14 rotates to the position of the metal contactor 15, it triggers the metal contactor 15 and transmits the signal to the MCU main controller. The MCU main controller then controls the rotary motor 2 to stop working.

[0021] A lowering limit switch 16 is installed on the sliding fixed plate 6, which can limit the descent of the lifting stepper motor 10.

[0022] The bottom of the lifting stepper motor 10 is provided with a lifting motor base 17, and the lifting motor base 17 is provided with a lifting limit switch 18, which can limit the lifting stepper motor 10 from rising.

[0023] Specifically, in this embodiment, the lower limit switch 16 is installed on the sliding fixed plate 6. When the liquid needle 13 is inserted into the vial 5, the lower limit switch 16 is triggered. The MCU main controller receives the signal and controls the lifting stepper motor 10 to stop descending. The upper limit switch 18 is installed on the side of the lifting motor base 17. When the liquid needle 13 rises away from the vial 5, the upper limit switch 18 is triggered. The MCU main controller receives the signal and controls the lifting stepper motor 10 to stop rising.

[0024] A vial limiting plate 19 is installed on the sliding fixing plate 6. The vial limiting plate 19 has a round hole, and the liquid-taking needle 13 can pass through the round hole of the vial limiting plate 19.

[0025] Specifically, in this embodiment, the liquid-taking needle 13 penetrates the vial limiting plate 19, which not only prevents the liquid-taking needle 13 from shaking during operation and affecting the liquid injection, but also locks the vial 5 and prevents it from shaking during operation.

[0026] A capillary support 20 is installed on the side of the lead screw fixing plate 9, and an adapter 21 is installed on the capillary support 20. One end of the adapter 21 is connected to the tubing of the liquid collection needle 13.

[0027] Specifically, in this embodiment, one end of the adapter 21 is connected to the liquid collection needle 13 pipeline, and the other end is connected to the entire equipment pipeline, ensuring the smooth flow of the entire pipeline.

[0028] The working principle of this utility model:

[0029] The vial 5 filled with the medicine is secured to the basket 4 and placed on the concave turntable 3. The MCU main control drives the rotary motor 2 to rotate the concave turntable 3 on the base plate 1. When the signal sensor 14 aligns with the metal contactor 15, the metal contactor 15 is triggered. The MCU main control receives the signal and controls the rotary motor 2 to stop working, thus determining the position of the first vial. Then, the lifting stepper motor 10 drives the lifting screw 11 to move downward, simultaneously causing the dispensing needle 13 installed under the screw fixing plate 9 to insert into the vial 5 until the lowering is triggered. When the limit switch 16 is activated, the MCU main controller receives a signal and controls the lifting stepper motor 10 to stop descending. When the liquid collection needle 13 rises and leaves the vial 5, it continues until the upper limit switch 18 is triggered. When the MCU main controller receives a signal, it controls the lifting stepper motor 10 to stop rising. The MCU main controller then drives the rotary motor 2 to continue rotating at a fixed angle to determine the position of the second vial. It then drives the lifting stepper motor 10 again to rotate the lifting screw 11 downward, causing the liquid collection needle 13 to move downward until the lower limit switch 16 is triggered to stop, thus realizing automatic quantitative liquid injection.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
