Description

Technical Field

[0001] This invention relates to the field of infusion, and in particular to a multifunctional infusion stand. Background Technology

[0002] Infusion stands are indispensable auxiliary equipment in the medical field, widely used in wards, emergency rooms, operating rooms, and other settings. They are mainly used to hang infusion bags and bottles, providing support for patients undergoing intravenous infusion therapy. However, with the advancement of medical technology and the diversification of clinical needs, traditional infusion stands have gradually revealed numerous problems, such as limited functionality and insufficient safety, making them unable to meet the requirements of modern medical use.

[0003] Traditional IV stands typically employ a simple "base-stand-hanging rod" structure, with their function limited to suspending IV fluids. To facilitate movement, the base of these stands is usually designed to be lightweight and equipped with casters. However, this lightweight design results in a high center of gravity and poor stability. During daily use, they are prone to tipping over due to collisions, uneven ground, or external forces such as patients pulling on the IV tubing. This can lead to interruptions in the IV infusion, needle dislodgement, damage to the IV container, waste of medication, and even patient injuries, posing a significant safety hazard to patients.

[0004] Some existing improved IV stands attempt to enhance stability by increasing the weight of the base or expanding the support area of ​​the base. However, while this approach can reduce the risk of tipping to some extent, it significantly increases the overall weight of the IV stand, resulting in reduced mobility and inconvenience for medical staff in handling and operating it. Furthermore, this type of passive anti-tipping design cannot cope with tilting caused by dynamic external forces, and its anti-tipping effect is limited.

[0005] In addition, the problem of the limited functionality of traditional IV stands is becoming increasingly prominent: if patients need assistance from medical staff during the IV infusion process, they need to use the ward call bell or be relayed by others, which is not timely enough.

[0006] In conclusion, the medical field urgently needs a multifunctional infusion stand that combines anti-tipping safety, versatility of functions, and ease of operation. Summary of the Invention

[0007] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of the present invention is to provide a multifunctional infusion stand.

[0008] The technical solution of the present invention is as follows: A multifunctional infusion stand, characterized in that it comprises:

[0009] The base has several casters at its bottom;

[0010] A support pole is mounted on the base and can extend and retract in the vertical direction. The top of the support pole is provided with several hanging rods arranged at intervals along the circumference of the support pole.

[0011] An anti-tipping module includes a tilt angle detection unit, an electromagnetic dynamic counterweight unit, and a power-off self-locking mechanism. The base has a hollow interior forming an installation cavity. The tilt angle detection unit and the electromagnetic dynamic counterweight unit are both located within the installation cavity. The electromagnetic dynamic counterweight unit includes a planar electromagnetic drive assembly and a counterweight block magnetically coupled to the planar electromagnetic drive assembly. The planar electromagnetic drive assembly is configured to drive the counterweight block to move two-dimensionally in a horizontal plane after being powered on. The power-off self-locking mechanism is configured to mechanically lock the counterweight block when the planar electromagnetic drive assembly loses power.

[0012] The main controller is located on the base and integrates a medical call device. The anti-tipping module is connected to the main controller. The main controller is used to receive signals from the tilt angle detection unit and control the planar electromagnetic drive assembly to drive the counterweight to move, so as to dynamically adjust the center of gravity of the infusion stand.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: This multifunctional infusion stand integrates multiple functions such as infusion suspension, flexible movement, anti-tipping protection, and medical call through a reasonable structural design. The anti-tipping module adopts a combination of tilt angle detection and dynamic counterweight adjustment, which can respond to the risk of tipping in real time and improve the safety of use. All functional modules work together, making it easy to operate and highly practical. It is suitable for various medical places such as hospitals and clinics, providing great convenience for patients and medical staff.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] The embodiments of the present invention are described in detail below.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0036] In the description of this invention, "first feature" and "second feature" may include one or more of the indicated features. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" and "second" may explicitly or implicitly include one or more of the indicated features.

[0037] The following description, with reference to the accompanying drawings, describes a multifunctional infusion stand according to an embodiment of the present invention. The infusion stand includes a base 1, a support rod 2, an anti-tipping module 3, and a main controller 4. It integrates multiple functions such as infusion suspension, anti-tipping protection, medical call, and auxiliary lighting, and is suitable for various medical scenarios, effectively improving the safety and convenience of the infusion process.

[0038] like Figures 1-3As shown, the base 1 has a stable disc-shaped structure with several casters 11 evenly distributed on the bottom. These casters 11 have a braking function, facilitating the flexible movement of the IV stand in wards, corridors, and other locations, and locking in place to prevent accidental slippage. Figure 4 As shown, the hollow interior of the base 1 forms a sealed mounting cavity 12, providing installation space for various components of the anti-tipping module 3.

[0039] like Figures 1-3 As shown, the support pole 2 is vertically fixed to the base 1 and adopts a telescopic structure design. Internally, it has multiple nested sleeves, which are secured by elastic locking elements or threaded locking mechanisms. Medical staff can adjust the overall length of the support pole 2 vertically according to the patient's height, bed height, and other actual needs. After adjustment, it is fixed by the locking mechanism to ensure the support pole 2 maintains the required height. The top of the support pole 2 has several integrally formed hanging rods 21, evenly spaced along the circumference of the support pole 2. Each hanging rod 21 has an anti-detachment hook at its free end, which can be used to hang infusion bags, infusion bottles, and other infusion containers. The design of multiple hanging rods 21 allows for multiple infusion operations simultaneously, meeting diverse clinical needs.

[0040] like Figures 1-3 As shown, a trash can 6 can also be detachably installed on the support pole 2. The trash can 6 is connected to the support pole 2 by a detachable structure such as a buckle or Velcro, which makes it convenient for patients to discard tissues, cotton swabs and other household waste during infusion. The detachable design also facilitates subsequent cleaning and replacement, keeping the environment around the infusion stand clean.

[0041] The anti-tipping module 3 is the core component that ensures the safe use of the infusion stand. It includes a tilt angle detection unit, an electromagnetic dynamic counterweight unit, and a power-off self-locking mechanism 34. All three are integrated into the mounting cavity 12 of the base 1. The layout is compact and reasonable, and does not affect the overall appearance and mobility of the infusion stand.

[0042] The tilt detection unit employs a high-precision dual-axis tilt sensor, fixedly installed on the inner wall of the mounting cavity 12. Its detection direction corresponds to the vertical axis of the infusion stand, enabling real-time detection of the tilt angle and angular velocity signals of the infusion stand in both front-to-back and left-to-right directions. The detected signals are transmitted to the main controller 4 in real time, providing data for anti-tipping control. This tilt sensor boasts high detection accuracy and fast response speed, promptly capturing even minute tilt changes of the infusion stand to ensure the timeliness and accuracy of anti-tipping control.

[0043] like Figure 4 and Figure 5As shown, the electromagnetic dynamic counterweight unit includes a planar electromagnetic drive component and a counterweight block 35 magnetically coupled to the planar electromagnetic drive component. When the planar electromagnetic drive component is energized, it can drive the counterweight block 35 to move in two dimensions in the horizontal plane. By adjusting the position of the counterweight block 35, the overall center of gravity of the infusion stand is changed, thereby counteracting the tilting trend and preventing the infusion stand from tipping over.

[0044] The mounting cavity 12 is equipped with a slide 31 that slides in the front-back direction. The slide 31 adopts a frame structure, and the counterweight 35 is slidably mounted on the slide 31 to form a two-dimensional moving mechanism of "front-back and left-right". The planar electromagnetic drive assembly includes a front-back electromagnetic drive assembly 32 and a left-right electromagnetic drive assembly 33, which are used to drive the front-back movement of the slide 31 and the left-right movement of the counterweight 35 on the slide 31, respectively.

[0045] like Figures 4-8 As shown, the mounting cavity 12 is provided with two partitions 13 extending in the front-back direction, dividing the mounting cavity 12 into three independent chambers: left, middle, and right. The slide 31 is located in the middle chamber, and the left and right chambers respectively house the front-back electromagnetic drive components 32. Each front-back electromagnetic drive component 32 includes a first electromagnet 321 and a first permanent magnet 322. Each chamber contains two first electromagnets 321, positioned opposite each other at opposite ends of the chamber in the front-back direction. The first permanent magnet 322 is located between the two first electromagnets 321. A first guide hole 14 extending in the front-back direction is provided on the partition 13. A first slider 323 slidably engages within the first guide hole 14, and the first permanent magnet 322 is fixedly connected to the side wall of the slide 31 via the first slider 323. When the front-back electromagnetic drive components 32 in the left and right chambers are energized, changing the direction and magnitude of the current in the first electromagnet 321 generates magnetic fields of different directions and intensities, driving the first permanent magnet 322 to move the slide 31 smoothly in the front-back direction.

[0046] The slide 31 has a hollow interior forming a sliding cavity. A left-right electromagnetic drive assembly 33 is installed within this cavity, comprising a second electromagnet 331 and a second permanent magnet 332. Two second electromagnets 331 are arranged opposite each other at opposite ends of the sliding cavity, and the second permanent magnet 332 is located between the two electromagnets 331. A second guide hole 311 extending left-right is provided on the side wall of the slide 31. A second slider slides within the guide hole 311. A counterweight 35 is fitted over the outside of the slide 31, and the second permanent magnet 332 is fixedly connected to the inner wall of the counterweight 35 via the second slider. Similarly, by controlling the energization state of the second electromagnet 331, the second permanent magnet 332 can be driven to move the counterweight 35 left-right, achieving two-dimensional movement adjustment of the counterweight 35 in the horizontal plane.

[0047] The counterweight 35 is made of high-density metal material and has a large mass, which can produce a significant center of gravity adjustment effect with a small moving distance. At the same time, the outer surface of the counterweight 35 is covered with a buffer rubber layer, which can reduce collision and wear with other parts during movement and reduce noise.

[0048] like Figures 6-9 As shown, the power-off self-locking mechanism 34 has two sets, corresponding to the front-to-back electromagnetic drive assembly 32 and the left-to-right electromagnetic drive assembly 33, respectively. It is used to mechanically lock the slide 31 and the counterweight 35 when the electromagnetic drive assembly loses power, to prevent them from being displaced by external force or their own weight, and to ensure the stability of the infusion stand in the power-off state.

[0049] The mounting cavity 12 of the base 1 is provided with a plurality of first limiting grooves 15 arranged at intervals along the front-to-back direction at the bottom, and the top surface of the slide 31 is provided with a plurality of second limiting grooves 312 arranged at intervals along the left-to-right direction. The limiting grooves are V-shaped or arc-shaped groove structures, which facilitates the insertion and locking of the pin 341.

[0050] The power-off self-locking mechanism 34 includes a pin 341, a spring 342, a third permanent magnet 343, and a third electromagnet 344. A support base is fixed on the slide 31. The pin 341 slides through the support base. The third permanent magnet 343 is fixedly installed at one end of the pin 341. The spring 342 is sleeved on the pin 341, and both ends of the spring 342 abut against the support base and the third permanent magnet 343, respectively. The third electromagnet 344 is fixedly installed at a position opposite to the third permanent magnet 343.

[0051] The first set of power-off self-locking mechanisms 34 has a pin 341 that corresponds to the first limiting groove 15 on the base 1. When the forward and backward electromagnetic drive component 32 is de-energized, the corresponding third electromagnet 344 is de-energized, the spring 342 returns to its natural state, and pushes the pin 341 into the first limiting groove 15 below, thus achieving mechanical locking of the slide 31. When the forward and backward electromagnetic drive component 32 is energized, the third electromagnet 344 is energized at the same time, generating a magnetic field opposite to that of the third permanent magnet 343, attracting the third permanent magnet 343 to drive the pin 341 to overcome the elastic force of the spring 342 and move upward, disengaging from the first limiting groove 15 and releasing the lock on the slide 31.

[0052] The second set of power-off self-locking mechanism 34 has a pin 341 that corresponds to the second limiting groove 312 on the slide 31. Its working principle is the same as that of the first set. When the left and right electromagnetic drive component 33 loses power, the pin 341 is locked into the second limiting groove 312 to lock the counterweight 35. When the power is on, the lock is released, ensuring that the counterweight 35 can move flexibly during the adjustment process and remains stable when the power is off.

[0053] The main controller 4 is fixedly installed on the outer wall of the base 1. The outer shell of the main controller 4 is designed to be waterproof and dustproof. The surface is equipped with an operation panel and a display screen. The operation panel is equipped with function buttons such as power switch, call button, and lighting adjustment button. The display screen can display information such as the tilt angle of the infusion stand and the position of the counterweight 35 in real time, which is convenient for medical staff to view.

[0054] The main controller 4 integrates a medical call device. Patients or medical staff can send a call signal to the nurse station by pressing the call button to quickly call for help. At the same time, the call signal will emit a prompt tone through the built-in speaker of the main controller 4 to ensure that the call information is delivered in a timely manner.

[0055] The main controller 4 is electrically connected to each component of the anti-tipping module 3 and is configured to execute the anti-tipping control method. The specific control logic is as follows:

[0056] Real-time acquisition of the tilt angle or angular velocity signal of the infusion stand detected by the tilt angle detection unit;

[0057] The acquired signal is compared with a preset safety threshold, which is set according to the structural parameters and safety standards of the IV stand.

[0058] When the detection signal exceeds the preset safety threshold, it is determined that there is a risk of the infusion stand tipping over. The control chip calculates the target compensation position that the counterweight 35 needs to move based on the signal data.

[0059] Send control commands to the planar electromagnetic drive assembly to drive the forward and backward electromagnetic drive assembly 32 and the left and right electromagnetic drive assembly 33 to work together, moving the counterweight 35 toward the target compensation position until the tilt angle of the infusion stand is restored to a safe range.

[0060] When the detection signal is lower than the preset safety threshold, the counterweight 35 is controlled to maintain its current position or return to its initial center position to ensure the stability of the infusion stand's center of gravity.

[0061] The support pole 2 is also equipped with a lighting unit 5, which is made of LED beads and is fixedly installed in the middle of the support pole 2 and electrically connected to the main controller 4. The lighting unit 5 is configured to have at least a lighting mode and a warning mode. Medical staff can switch modes through the operation panel of the main controller 4: In the lighting mode, the LED beads emit a soft white light to provide local lighting for patients, facilitating operations such as intravenous infusion and medication administration at night; in the warning mode, the LED beads emit a flashing red or yellow light, which can be turned on when the patient suddenly feels unwell and needs emergency assistance, serving to alert medical staff and those around them.

[0062] During the use of the IV stand, the tilt detection unit continuously monitors the tilt status of the IV stand and transmits the signal to the main controller 4. When the IV stand tilts due to collision, uneven ground, or other external forces, and the tilt angle exceeds the preset safety threshold, the main controller 4 immediately activates the anti-tipping control program. Based on the tilt direction and angle, it calculates the compensation position of the counterweight 35, then controls the planar electromagnetic drive assembly to be energized, releasing the power-off self-locking mechanism 34, and driving the slide 31 and counterweight 35 to move in the corresponding compensation direction, adjusting the center of gravity of the IV stand to counteract the tilting force. When the tilt detection unit detects that the IV stand has returned to a safe state, the main controller 4 controls the counterweight 35 to maintain its current position or return to the center position to ensure the stability of the IV stand.

[0063] If the IV stand loses power, the planar electromagnetic drive component loses power, and the spring 342 of the power-off self-locking mechanism 34 pushes the pin 341 into the corresponding limit groove, locking the slide 31 and the counterweight 35 in the current position to prevent them from moving at will and causing the IV stand to tip over, thus ensuring the safety of the IV infusion process.

[0064] If a patient needs assistance during an infusion, they can press the call button on the main controller 4 to send a call signal to the nurse station via the medical call device; when lighting is needed at night, the lighting unit 5 can be turned on; in case of an emergency, the system can be switched to warning mode to send a flashing signal to alert for help.

[0065] In summary, this multifunctional infusion stand integrates multiple functions such as infusion suspension, flexible movement, anti-tipping protection, and medical call function through a reasonable structural design. Among them, the anti-tipping module 3 adopts a combination of tilt angle detection and dynamic counterweight adjustment, which can respond to the risk of tipping in real time and improve the safety of use. All functional modules work together, making it easy to operate and highly practical. It is suitable for various medical places such as hospitals and clinics, providing great convenience for patients and medical staff.
