Technical Field

[0001] This application relates to the field of medical devices, and in particular to a medicine bottle shaking device. Background Technology

[0002] In the medical industry, thorough mixing of medications is a crucial step in ensuring therapeutic efficacy. With industry development and technological advancements, this field has undergone significant transformation, evolving from initial reliance on manual shaking to the gradual introduction of mechanized and automated equipment. These changes have not only greatly improved the efficiency and accuracy of medication mixing but also effectively reduced the workload of medical staff, providing vital assurance for patient safety. Especially in modern medical institutions, efficient bottle shaking devices have become indispensable, further promoting the overall improvement of medical service levels.

[0003] In related technologies, to address the need for drug mixing, medical staff typically shake the medicine bottle by hand.

[0004] The aforementioned technologies have the following drawbacks: In practical applications, manually shaking medicine bottles is accompanied by a high level of operational noise, which poses a significant challenge to medical facilities that seek a quiet environment. Utility Model Content

[0005] To reduce the operating noise associated with shaking medicine bottles, this application provides a medicine bottle shaking device.

[0006] The medicine bottle shaking device provided in this application adopts the following technical solution:

[0007] A medicine bottle shaking device includes a dispensing platform and a shaking unit. The shaking unit includes a fixed base plate connected to the dispensing platform and a medicine clamping assembly. The medicine clamping assembly is vertically mounted on the fixed base plate and is connected to the fixed base plate with a shock-absorbing assembly.

[0008] By adopting the above technical solution, the basic structural design of the medicine bottle shaking device has been realized. The specific effects are as follows: the medicine clamping component is vertically and flexibly mounted on the fixed base plate, allowing the medicine bottle to move stably up and down in the vertical direction, thereby effectively improving the efficiency and uniformity of medicine mixing. The shock absorption component significantly reduces the vibration and noise generated during device operation, optimizing the working environment, and is particularly suitable for work scenarios requiring quiet operation, such as operating rooms and laboratories.

[0009] Preferably, the drug clamping assembly and the fixed base plate are connected to a voice coil motor.

[0010] By adopting the above technical solution, the introduction of a voice coil motor enables precise driving of the medicine clamping assembly relative to the fixed base plate, allowing the medicine bottle to perform stable reciprocating motion in the vertical direction. This design effectively replaces the traditional manual shaking method, significantly improving the efficiency and stability of medicine bottle shaking, while greatly reducing operating noise and optimizing the working environment. As the core power component, the voice coil motor ensures the operational precision of the entire device, reducing errors caused by human factors, thereby ensuring that the liquid medicine can be mixed quickly and evenly.

[0011] Preferably, the drug clamping assembly includes a movable support and multiple grippers, the movable support being mounted on the end of the voice coil motor away from the fixed base plate; the multiple grippers are movably mounted on the movable support.

[0012] By adopting the above technical solution, stable clamping and flexible adjustment of medicine bottles are achieved. The cooperation between the movable bracket and the voice coil motor allows the medicine clamping assembly to move smoothly in the vertical direction, and the design of multiple movable grippers can adapt to medicine bottles of different sizes and shapes, thereby improving the versatility of the device. This design effectively reduces the inconvenience caused by differences in medicine bottle specifications and further improves the stability and efficiency during the shaking process of the medicine bottle.

[0013] Preferably, the movable bracket is equipped with a guide post arranged along the length direction of the voice coil motor, and the guide post is slidably connected to the fixed base plate.

[0014] By adopting the above technical solution, the guide column allows the movable support to slide smoothly along the length of the voice coil motor, effectively limiting the degree of freedom of the movable support and preventing it from shifting or wobbling during movement, thereby improving the stability of the medicine bottle shaking process. At the same time, the sliding connection structure between the guide column and the fixed base plate is simple and reliable, helping to reduce friction noise and further optimizing the working environment of the device.

[0015] Preferably, the guide post is fitted with a linear bearing that is connected to the fixed base plate.

[0016] By adopting the above technical solution, the linear bearing effectively reduces the frictional resistance between the guide column and the fixed base plate, making the lifting and lowering movement of the medicine clamping assembly driven by the voice coil motor smoother and more stable. This further improves the stability and accuracy during the shaking process of the medicine bottle, while reducing noise caused by friction, thereby optimizing the overall performance of the device and the user experience.

[0017] Preferably, the shock absorption assembly includes a first spring arranged along the length of the voice coil motor, one end of the first spring being connected to the fixed base plate and the other end being connected to the movable bracket.

[0018] By adopting the above technical solution, the first spring effectively buffers the vibration and impact generated during the shaking of the medicine bottle, thereby significantly reducing the noise during device operation and improving the working environment. Furthermore, the first spring also enhances the stability of the medicine bottle during shaking, preventing the bottle from becoming loose or causing uneven mixing due to excessive vibration, further improving the mixing effect and operational safety.

[0019] Preferably, the first spring is sleeved on the guide post, and both ends of the first spring are provided with first elastic washers sleeved on the guide post.

[0020] By adopting the above technical solution, the first spring sleeved on the guide column can effectively absorb the vibration energy generated during the shaking of the medicine bottle, thereby significantly reducing the noise and improving the stability of the device during operation. The setting of the first elastic gasket further avoids rigid contact between the first spring and the movable bracket and the fixed base plate, preventing additional noise or damage to parts due to direct collision of metal parts, and ensuring the long-term stable and reliable operation of the entire system.

[0021] Preferably, the end of the guide column away from the movable bracket is provided with a magnetic suction plate, and the dispensing platform is provided with an electromagnet that is spaced apart from the magnetic suction plate.

[0022] By adopting the above technical solution, the interaction between the magnetic plate and the electromagnet provides additional attraction or repulsion when the voice coil motor drives the drug gripping assembly, thereby enhancing the stability and accuracy of the entire system. Specifically, this design effectively prevents the drug gripping assembly from shifting or vibrating excessively during reciprocating motion, further reducing noise and improving the efficiency and stability of bottle shaking. Furthermore, this design increases the device's functional flexibility, allowing the magnetic field strength of the electromagnet to be adjusted according to actual needs to accommodate different bottle sizes.

[0023] Preferably, a second spring is provided between the magnetic suction plate and the fixed base plate, and a second elastic washer is provided at both ends of the second spring, which is also provided on the guide post.

[0024] By adopting the above technical solution, a second spring and a second elastic washer are added between the magnetic suction plate and the fixed base plate. The second spring can further enhance the shock absorption performance of the system, effectively reducing the transmission of vibrations generated during the shaking of the medicine bottle to the dispensing platform, thereby significantly reducing noise and improving operational stability. At the same time, the second elastic washer avoids hard contact between the spring and the guide column, preventing wear and extending service life, and ensuring the reliability and consistency of the entire device during long-term operation.

[0025] Preferably, the dispensing platform is provided with a turntable, and there are multiple shaking units distributed along the circumference of the turntable; the fixed base plate is detachably connected to the turntable.

[0026] By adopting the above technical solution, multi-station operation is achieved, improving the functionality and applicability of the equipment. Specifically, a turntable with multiple shaking units distributed circumferentially on it allows a single unit to process multiple medicine bottles simultaneously, significantly improving work efficiency. The detachable connection between the fixed base plate and the turntable facilitates the replacement or maintenance of the shaking units according to different needs, increasing the flexibility and practicality of the device.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The combination of voice coil motor and vibration damping components in this application significantly reduces operating noise and optimizes the working environment, making it particularly suitable for quiet environments such as operating rooms and laboratories.

[0029] 2. The design of the guide column and spring in this application enhances the stability and shock resistance of the medicine bottle during shaking, ensuring that the medicine can be fully mixed in a short time and improving work efficiency.

[0030] 3. The multiple support structure between the magnetic plate and the guide column in this application improves the functionality and applicability of the device, enabling the equipment to maintain good operating condition under different conditions. Attached Figure Description

[0037] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0038] This application discloses a medicine bottle shaking device.

[0039] Reference Figure 1 , Figure 2 and Figure 3 A medicine bottle shaking device includes a dispensing platform 1 and a shaking unit 2. The shaking unit 2 includes a fixed base plate 21 and a medicine clamping assembly 22, which are connected by a shock-absorbing assembly 25. Specifically, the fixed base plate 21 is mounted on the dispensing platform 1, and the medicine clamping assembly 22 is vertically and flexibly mounted on the fixed base plate 21 and connected to the shock-absorbing assembly 25. A voice coil motor 23 is connected to the medicine clamping assembly 22 and the fixed base plate 21, and the voice coil motor 23 drives the medicine clamping assembly 22 to move up and down.

[0040] Reference Figure 1 , Figure 2 and Figure 3 The medicine clamping assembly 22 includes a movable support 221 and multiple grippers 222. The movable support 221 is mounted on the end of the voice coil motor 23 away from the fixed base plate 21, and the multiple grippers 222 are movably mounted on the movable support 221. The movable support 221 is a rectangular frame structure, which can be made of high-strength aluminum alloy or other lightweight metal materials, possessing good strength and weight characteristics while being easy to process and shape. It is fixed to the top side of the voice coil motor 23 by bolts or other fasteners, and the voice coil motor 23 is firmly placed in the center of the fixed base plate 21. To better position the voice coil motor 23 before fixing, a vibrator limiting ring 231 is provided on the fixed base plate 21, and the voice coil motor 23 is installed inside the vibrator limiting ring 231. The grippers 222 can be made of materials such as stainless steel or plastic, and their surfaces are finely polished to prevent scratching the surface of the medicine bottle. Each gripper 222 is equipped with a miniature ball screw pair or other precision transmission mechanism as a drive source, so that each gripper 222 can be precisely translated and adjusted on the movable bracket 221 to ultimately form a stable and reliable gripping state to envelop the target medicine bottle to be shaken.

[0041] Reference Figure 1 , Figure 2 and Figure 3 To ensure smooth and stable operation of the entire mechanism and reduce frictional losses, a guide post 24 is installed on the movable bracket 221 along the length of the voice coil motor 23. The guide post 24 is slidably connected to the fixed base plate 21. A linear bearing 241 connected to the fixed base plate 21 is fitted on the guide post 24.

[0042] Reference Figure 1 , Figure 2 and Figure 3 The vibration damping assembly 25 includes a first spring 251 arranged along the length of the voice coil motor 23. One end of the first spring 251 is connected to the fixed base plate 21, and the other end is connected to the movable bracket 221. The first spring 251 is sleeved on the guide post 24, and both ends of the first spring 251 are provided with first elastic washers 2510 sleeved on the guide post 24. The first spring 251 and the first elastic washers 2510 work together to reduce the vibration and noise generated by the vibration during the operation of the voice coil motor 23.

[0043] Reference Figure 1 , Figure 2 and Figure 3 A magnetic suction plate 26 is provided at the end of the guide column 24 away from the movable bracket 221, and an electromagnet 261 is provided on the dispensing platform 1, spaced apart from the magnetic suction plate 26. After the medicine bottle is placed in the correct position and the operation process is started, the electromagnet 261, which is pre-embedded in a specific part of the dispensing platform 1, will be energized in time to generate a strong attraction to tighten the magnetic suction plate 26, indirectly enhancing the overall anti-interference ability and control precision during the entire shaking process. At the same time, the voice coil motor 23 can control the attraction force generated by the magnetic suction plate 26 or release the attraction force by changing the current, thereby optimizing the shaking action and force adaptability of the medicine bottle.

[0044] Reference Figure 1 , Figure 2 and Figure 3 A second spring 252 is provided between the magnetic suction plate 26 and the fixed base plate 21, and is sleeved on the guide post 24. Both ends of the second spring 252 are provided with second elastic washers 2520 sleeved on the guide post 24. This further improves the effect of shock absorption and noise reduction.

[0045] Reference Figure 1 , Figure 2 and Figure 3To improve work efficiency, the dispensing platform 1 is equipped with a turntable 11 and a receiving slot 101 opposite to the turntable 11, with an electromagnet 261 located inside the receiving slot 101. The turntable 11 has a coaxial rotating shaft 12, which is rotatably connected to the dispensing platform 1 and driven by a drive component 13 mounted on the dispensing platform 1. The drive component 13 is a conventional component such as a motor. Multiple shaking units 2 are distributed along the circumference of the turntable 11; the fixed base plate 21 is detachably connected to the turntable 11. This allows for the rational planning of the sample placement sequence and route arrangement schedule according to actual needs, easily achieving continuous, high-efficiency, batch production capacity improvement and upgrading, making the desired outcome a reality.

[0046] The implementation principle of the medicine bottle shaking device in this embodiment is as follows:

[0047] After the medicine clamping assembly 22 grips the medicine with multiple grippers 222, the voice coil motor 23 is activated, causing the medicine bottle clamping assembly to reciprocate in the vertical direction. The shock absorption assembly 25 reduces vibration during shaking, and the magnetic field provided by the magnetic suction plate 26 enhances the stability of the system. After shaking is complete, the motor is turned off, and the medicine bottle can be removed.
