Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to an automatic mixer for medical injection solutions. Background Technology
[0002] Automatic medical injection mixers are currently used to automatically mix various injection solutions. Their main function is to mechanically and uniformly mix multiple drug solutions, reducing manual operation, making it more precise, time-saving, and labor-saving, meeting current clinical drug use needs, and suitable for centralized drug preparation in hospitals, with higher efficiency.
[0003] Existing technologies are mainly divided into two categories: manual mixing and automated equipment mixing. Medical liquids are highly hygienic and safe, so this equipment has strong sealing to avoid cross-infection. The mixing accuracy is higher than that of manual mixing, and the instruments are becoming more intelligent with the development of the times, making them simple and convenient to operate and saving time and costs.
[0004] Because current automated drug mixing equipment designs prioritize the precision of drug mixing standards and the airtightness of the structure, they lack a mixing and shaking device. Most of the mixing is done manually, which is labor-intensive, time-consuming, and prone to cross-infection. Therefore, an automated medical injection solution mixer is proposed to solve the above problems. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figures 1-3 This utility model provides an embodiment of an automatic medical injection mixer, comprising a base 1, a support plate 2 fixedly connected to the top of the base 1, both serving to support related fixed structures and maintain stability; a sliding plate 3 fixedly connected to the front side of the support plate 2, the sliding plate 3 having a groove 13 inside, a slider 14 slidably connected inside the groove 13, a sliding connecting rod 4 fixedly connected to the front side of the slider 14; a support bar 15 fixedly connected to the bottom of the sliding plate 3, and a motor 17 fixedly connected to the rear side of the support bar 15. A turntable 5 is fixedly connected to the output end, and a sliding column 16 is fixedly connected to the outer edge of the turntable 5. The motor outputs current to the turntable 5, and the sliding column 16 on the turntable 5 will rotate together, thereby driving the sliding groove connecting rod 4 to start operating. One end of the sliding groove connecting rod 4 is connected to the slider 14, so it will slide left and right in the groove 13 with the slider 14 to achieve a shaking effect, so that the liquid medicine is mixed evenly and thoroughly. A housing 6 is fixedly connected to the front side of the sliding groove connecting rod 4 for placing the mixing equipment and fixing the structural device. The whole structure sways together with the upper connecting rod structure.
[0032] Reference Figure 1 and Figure 4A protective shell 7 is fixedly connected to the right outer wall of the outer casing 6 to prevent corrosion and oxidation caused by changes in external air humidity, protect the internal structure and enhance its appearance. A motor 19 is fixedly connected inside the protective shell 7. A rotating shaft 21 is fixedly connected to the output end of the motor 19. Two inner connecting rods 22 are fixedly connected to the outer wall of the rotating shaft 21. The ends of the two inner connecting rods 22 away from the rotating shaft 21 are rotatably connected to outer connecting rods 23. The ends of the two outer connecting rods 23 away from the inner connecting rods 22 are fixedly connected to grippers 24. The motor 19 transmits current to the rotating shaft 21, causing it to rotate. Therefore, the two inner connecting rods 22 fixedly connected to the rotating shaft 21 will cause the outer connecting rods 23 connected to their ends to start operating. Grippers 24 are installed on the outer connecting rods 23. The overall structure serves to fix the sealed syringe and other equipment, preventing the equipment from slipping during the swinging process and causing damage and loss. Therefore, this structure is safer.
[0033] Reference Figure 1 The top of the base 1 is fixedly connected to a control console 8, and the front of the control console 8 is fixedly connected to a display panel 11. The display panel 11 is used for intelligent operation, controlling time, speed, etc. The front of the control console 8 is fixedly connected to a switch 10 to control the power supply. The control console 8 has multiple placement slots 9 inside, so that the products can be temporarily placed when they are mixed together, and then stored together after the event.
[0034] Reference Figure 1 The bottom of the outer casing 6 has a fixing groove 18 for placing equipment such as syringes or test tubes, which makes it more stable.
[0035] Reference Figures 2-3 The support plate 2 is fixedly connected to the rear side of the protective shell 12. The motor 17 is fixedly connected to the outside of the protective shell 12. The protective shell serves to prevent oxidation and corrosion, prevent damage to the internal structure, and make it more aesthetically pleasing.
[0036] Reference Figure 3 The sliding column 16 is slidably connected inside the sliding groove connecting rod 4. After receiving current, the sliding column 16 slides inside the connecting rod, driving the operation of the connecting rod structure and other structures.
[0037] Reference Figure 4 The inner wall of the outer shell 6 is fixedly connected to a sliding groove strip 20, and the gripper 24 is slidably connected inside the sliding groove strip 20. It slides and moves within its sufficient space to achieve the effects of clamping and loosening.
[0038] Reference Figure 4 The rotating shaft 21 is rotatably connected inside the slide bar 20 and is connected to the motor output end. It is more enclosed inside and more protective.
[0039] Working principle: First, place the closed syringe or test tube containing multiple medicines that needs to be shaken and mixed into the fixed groove 18 inside the outer shell 6. After placement, the current from the output end of motor 2 (19) drives the rotating shaft 21 to start operating. The rotating shaft 21 starts to rotate, and the two inner connecting rods 22 are fixed on the rotating shaft 21. Therefore, the outer connecting rods 23 at both ends of the inner connecting rods 22 also start to operate, thereby driving the gripper 24 on it to slide horizontally within the slide bar 20 to the edge of the syringe or test tube, gripping and locking it firmly. After fixing it, press the switch 10 button, and motor 1 17 starts to output current to the turntable 5. The turntable 5 starts to rotate, which will drive the slide column 16. The slide rod 4 slides circumferentially inside the slide rail 4, and the slide rail 4 also starts to move at any time. Since one end of the slide rail 4 is fixedly connected to the slider 14, the slider 14 will also slide left and right in the groove 13 inside the slide rail 3. Since the outer shell 6 is fixed on the slide rail 4, the equipment fixed inside the outer shell 6 will also swing left and right evenly, so that the various liquids are mixed evenly and the liquid output is more stable. After shaking, the power can be turned off, the gripper 24 can be released, and the structure will return to its original state. During operation, the corresponding time and shaking speed can be set through the display panel 11. If the mixing is concentrated, the mixed equipment can be placed in multiple placement slots 9 for temporary storage.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
