[0044] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0045] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0046] 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 technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0047] Currently, during intravenous infusion, infusion bags and bottles are typically secured using an infusion stand. However, some medications are prone to sedimentation or even stratification when suspended for extended periods. Furthermore, certain medications (such as biological cell solutions, nutrient solutions, and suspensions) require a high degree of homogeneity. To ensure homogeneity, medical staff currently rely on periodic manual shaking. However, this method is tedious for medical personnel, and manual shaking cannot guarantee consistent homogeneity. Moreover, the time interval between shaking sessions can be easily affected by unforeseen events.

[0048] At the same time, manual shaking by medical staff can easily result in poor mixing, and the medicine solution may still be uneven after shaking.

[0049] Based on the above considerations, in order to alleviate the problems of low efficiency and poor mixing effect caused by the need for medical staff to manually shake the liquid medicine, this application provides an infusion stand. A first swingable support member is provided inside the shell of the infusion stand to support a first liquid medicine container. The first liquid medicine container is driven to swing through the first support member by a drive component. A fixing component is also provided to fix the first liquid medicine container on the first support member so that the first liquid medicine container can move synchronously with the first support member.

[0050] In this infusion stand, the drive assembly can drive the first support member to swing, and the first support member can drive the first medicine container to swing and shake, thereby ensuring that the medicine is in a more uniform state and reducing the risk of medicine sedimentation. At the same time, a fixing assembly is also provided to fix the first medicine container to the first support member, thereby reducing the relative movement between the first medicine container and the first support member, allowing the first support member to better drive the first medicine container to swing, thus shaking the first medicine container more evenly and ensuring that the medicine is in a more uniform state.

[0051] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0052] refer to Figures 1 to 3 , Figure 6 This application provides an infusion stand 100, including a support 10, a first support member 20, and a drive assembly 30. The support 10 includes a base 11 and a housing 12 connected to the base 11, the housing 12 having a receiving space 121. The first support member 20 is rotatably connected to the housing 12 and received within the receiving space 121. A fixing assembly 21 is provided on the first support member 20 for holding a first medicine container. The drive assembly 30 is disposed on the housing 12 and connected to the first support member 20 to drive the first support member 20 to reciprocate relative to the housing 12.

The material of the housing 12 can be the same as or different from the material of the base 11.

[0057] The accommodating space 121 refers to the spatial structure inside the shell 12. The accommodating space 121 can be a prism-shaped space, a cylindrical space, or a spatial structure of other shapes. When the shell 12 has an accommodating space 121, the shell 12 can include an openable and closable cover to open or close the accommodating space 121. The cover can be rotatably connected to the shell 12 or detachably connected to the shell 12 by means of a buckle, bolt, or other structure.

[0058] The first support member 20 refers to the structure in the infusion stand 100 used to support the first medicine container. The first support member 20 can be a plate-shaped structure, a column-shaped structure, or a structure of other shapes. When the first support member 20 is a plate, it can be a square plate, a circular plate, or a plate of other shapes. The material of the first support member 20 can include metal, plastic, or other materials.

[0059] The first support member 20 is rotatably connected to the housing 12 and housed in the receiving space 121, so that the first support member 20 can swing relative to the housing 12 within the receiving space 121; the first support member 20 can be rotatably connected to the housing 12 via a pivot, at which time the first support member 20 can swing around the pivot, and the first support member 20 can also be rotatably connected to the housing 12 in other ways.

[0060] The first support member 20 is provided with a fixing component 21. The fixing component 21 refers to the structure on the first support member 20 used to fix the first liquid container. The fixing component 21 can fix the first liquid container on the first support member 20 so that the first liquid container can swing synchronously with the first support member 20 when the first support member 20 swings.

[0061] For example, the fixing component 21 can be an arc-shaped pressure plate structure that is fastened to the first liquid container. In this case, the arc-shaped pressure plate structure can be installed on the first support member 20 by bolts and press the first liquid container onto the first support member 20. For example, the fixing component 21 can include two openable and closable claws 211. The two claws 211 can clamp the first liquid container to fix the first liquid container. It is understood that the pressing component can also include other structures, and is not limited to the two structures mentioned above.

[0062] The drive assembly 30 refers to the structure in the infusion stand 100 used to drive the first support member 20 to swing relative to the housing 12. The drive assembly 30 may include a motor, or a rotary cylinder or other rotary drive structure. The drive assembly 30 may also include a combination of a cylinder with a worm gear, a hydraulic cylinder with a gear rack or other linear feed mechanism with a transmission structure. The drive assembly 30 can drive the housing 12 to swing periodically to shake the first medicine container and mix the medicine.

[0063] The drive assembly 30 is disposed on the housing 12. The drive assembly 30 may be located inside the receiving space 121 or outside the receiving space 121.

[0064] In this embodiment, medical personnel can place the first medicine container on the first carrier 20 and fix the first medicine container with the fixing component 21; then, the driving component 30 is activated to drive the first carrier 20 to reciprocate periodically, so that the medicine is in a relatively uniform state. The driving component 30 can always be in the activated state to drive the first carrier 20 to shake the first medicine container. The driving component 30 can also be started and stopped intermittently to drive the first carrier 20 to shake the medicine container intermittently.

[0065] In this embodiment, a first support member 20 that can swing relative to the housing 12 is provided inside the housing 12, and a driving component 30 is provided so that the first support member 20 can swing through the driving component 30, thereby driving the first medicine container to swing, achieving the effect of shaking the medicine. At the same time, a fixing component 21 is provided on the first support member 20 so as to fix the first medicine container through the fixing component 21, so that the first medicine container can swing more synchronously with the first support member 20, thereby improving the shaking effect.

[0066] refer to Figures 3 to 5In some embodiments, the fixing component 21 includes a clamping member and a driving member 212 connected to the clamping member. The clamping member is movably disposed on the first bearing member 20, and the driving member 212 is used to drive the clamping member to move to clamp the first liquid medicine container.

[0067] The clamping component refers to the structure in the fixing assembly 21 used to contact and clamp the first liquid container. The clamping component can be a plate structure, a frame structure, or other structures. The material of the clamping component can include metal, plastic, or other materials.

[0068] The clamping member is movably mounted on the first support member 20. The first support member 20 may be provided with a sliding groove, and one end of the clamping member is slidably placed in the sliding groove so that the clamping member can move relative to the first support member 20.

[0069] The number of clamping members can be one. In this case, one clamping member can be close to the first liquid container and hold the first liquid container against the inner wall of the outer shell 12 or other structural members.

[0070] The number of clamping members can also be two. In this case, both clamping members can be movably disposed on the first bearing member 20. The two clamping members can move closer to each other to clamp the first liquid container. Alternatively, only one of the two clamping members can move to press the first liquid container onto the other clamping member and fix the first liquid container.

[0071] The driving component 212 refers to the structure in the fixed assembly 21 used to drive the movement of the clamping component. The driving component 212 may include linear feed devices such as cylinders, hydraulic cylinders, and electric push rods, or it may include lead screws or other mechanical structures. The driving component 212 is connected to the first bearing component 20. Depending on the structure of the driving component 212, the driving component 212 may be connected to the first bearing component 20 by screwing, welding, bonding or other means.

[0072] The drive unit 212 can drive the clamping member to move in order to clamp or release the first liquid container.

[0073] This embodiment provides a specific structure of some fixing components 21, setting up clamping members, and driving the clamping members to move through the driving member 212 so that the clamping members can fix or release the first liquid container.

[0074] refer to Figures 3 to 5 In some embodiments, the clamping member includes two grippers 211, which are movably mounted on the first support member 20 and are spaced apart along a first direction, which is perpendicular to the height direction of the bracket 10; the driving member 212 is connected to the two grippers 211 to drive the two grippers 211 to move closer to each other or further away from each other along the first direction.

[0075] The gripper 211 refers to the structure in the fixing component 21 used to contact and hold the first liquid container. The gripper 211 can be a plate structure, a frame structure or other structures. The material of the gripper 211 can include metal, plastic or other materials.

[0076] There are two grippers 211, and the two grippers 211 are movably mounted on the first support member 20. The first support member 20 may be provided with a sliding groove, and one end of the gripper 211 is slidably placed in the sliding groove so that the gripper 211 can move relative to the first support member 20. The two grippers 211 are spaced apart along a first direction, and the gap between the two grippers 211 is used to accommodate the first medicine container. The first direction is perpendicular to the height direction of the infusion stand 100. The first direction can be the width direction of the support 10, the thickness direction of the support 10, or other directions.

[0077] The driving component 212 refers to the structure in the fixed assembly 21 used to drive the two grippers 211 to move. The number of driving components 212 can be one or two. When there is one driving component 212, one driving component 212 can synchronously drive the two grippers 211 to move closer or further away from each other. When there are two driving components 212, the two driving components 212 can drive the two grippers 211 respectively and drive the two grippers 211 to move closer or further away from each other.

[0078] For example, the drive unit 212 can be a double-headed cylinder and connected to both grippers 211 to drive the two grippers 211 to move closer or further apart.

[0079] When the two grippers 211 are close together, they can grip and fix the first liquid container; when the two grippers 211 are far apart, they can release the first liquid container. At the same time, the distance between the two grippers 211 is adjustable so that the fixing component 21 can adapt to first liquid containers of different sizes.

[0080] During the process of medical staff installing the first liquid container onto the first carrier 20, the two grippers 211 can be moved away from each other by the drive member 212 first; then, the first liquid container is placed between the two grippers 211, and the two grippers 211 are moved closer to each other by the drive member 212 until the two grippers 211 clamp and fix the first liquid container.

[0081] This embodiment provides a specific structure for some fixing components 21, which are provided with two grippers 211 that can move closer or further apart from each other. The first liquid container is fixed by the two grippers 211 moving closer together. At the same time, the grippers 211 moving further apart can loosen the first liquid container for easy replacement and installation, and also make the fixing components 21 adaptable to first liquid containers of different sizes, thus expanding the applicability of the infusion stand 100.

[0082] refer to Figures 3 to 5 In some embodiments, the drive member 212 includes a rod portion 2121 and two threaded portions 2122 connected to both ends of the rod portion 2121. The rod portion 2121 is rotatably connected to the first bearing member 20, and the threads of the two threaded portions 2122 have opposite directions of rotation. The gripper 211 includes a gripper body 2111, which is sleeved on the threaded portion 2122 and threadedly engaged with the threaded portion 2122.

[0083] The rod portion 2121 refers to the part of the drive member 212 that provides a fixed foundation for the threaded portion 2122 or other structures. The rod portion 2121 is also the part of the drive member 212 that is connected to the first bearing member 20. The rod portion 2121 can be a cylindrical structure or a structural member of other shapes. The rod portion 2121 is rotatably connected to the first bearing member 20. A bearing seat and a bearing can be provided on the first bearing member 20, and the rod portion can pass through the bearing so that the rod portion can rotate relative to the first bearing member 20.

[0084] The threaded part 2122 refers to the part of the drive member 212 with threads on its outer surface. There are two threaded parts 2122, which are located at both ends of the rod part 2121 respectively. The threaded part 2122 can be connected to the rod part 2121 by welding, bonding or other means, or the threaded part 2122 can be integrally formed with the rod part 2121.

[0085] The gripper body 2111 refers to the structure in the gripper 211 that is used to directly contact and hold the first liquid container. The gripper body 2111 can be a plate-shaped structure, a frame structure, or a structure of other shapes.

[0086] The gripper body 2111 is sleeved on the threaded part 2122 and threadedly engaged with the threaded part 2122. That is, the gripper body 2111 may have a through hole and an internal thread in the through hole. The internal thread engages with the threaded part 2122 so that the rotation of the threaded part 2122 can drive the gripper body 2111 to move along the axial direction of the threaded part 2122.

[0087] When the gripper 211 can move along the first direction, the two threaded portions 2122 are located at both ends of the rod portion 2121 along the first direction, and the sliders 2112 of the two grippers 211 are threadedly engaged with the two threaded portions 2122 respectively; since the threads of the two threaded portions 2122 are opposite, the rotation drive member 212 can drive the two grippers 211 to move closer to each other or further away from each other through the two threaded portions 2122.

[0088] For example, a slider 2112 can be provided on the gripper body 2111, so that the slider 2112 is sleeved on the threaded part 2122 and the slider 2112 is threadedly engaged with the threaded part 2122. That is, the slider 2112 has a through hole and an internal thread in the through hole. The internal thread engages with the threaded part 2122 so that the rotation of the threaded part 2122 can drive the slider 2112 to move along the axial direction of the threaded part 2122, and drive the gripper body 2111 to move synchronously with the slider 2112.

[0089] During the process of medical staff installing the first liquid container onto the first carrier 20, the drive component 212 can be rotated first to make the two grippers 211 move away from each other; then, the first liquid container is placed between the two grippers 211, and the drive component 212 is rotated in the opposite direction to make the two grippers 211 move closer to each other until the two grippers 211 clamp and fix the first liquid container.

[0090] This embodiment further provides some specific structures of the driving component 212, and sets two threaded portions 2122 with opposite thread directions so that the rotation of the driving component 212 can drive the two grippers 211 to move synchronously, which simplifies the adjustment of the grippers 211 and makes it easier for the user to operate.

[0091] refer to Figure 4 , Figure 6 In some embodiments, the drive assembly 30 includes a first drive motor 31 and a gearbox 32. The first drive motor 31 is connected to the housing 12, the input end of the gearbox 32 is connected to the output end of the first drive motor 31, and the output end of the gearbox 32 is connected to the first support member 20. The gearbox 32 is located on the side of the first support member 20 away from the fixing assembly 21, and the first drive motor 31 is located on the side of the gearbox 32 away from the first support member 20.

[0092] The first drive motor 31 refers to the structure in the drive assembly 30 that provides power for the swing of the first carrier 20. The first drive motor 31 can be a servo motor, a stepper motor, or other types of motors. The first drive motor 31 is connected to the housing 12. The first drive motor 31 can be connected to the housing 12 by bonding, screwing, snapping, or other means.

[0093] The transmission 32 refers to the structure in the drive assembly 30 used to change the power output of the first drive motor 31. The transmission 32 can be a fixed gear ratio transmission, a multi-speed transmission, a continuously variable transmission, or other types of transmission.

[0094] The input end of the transmission 32 is connected to the output end of the first drive motor 31 so that the speed and torque output by the first drive motor 31 can be transmitted to the transmission 32. The output end of the transmission 32 is connected to the first support member 20. The transmission 32 can change the speed and torque output by the first drive motor 31 and can output the changed speed and torque to the first support member 20 to drive the first support member 20 to swing.

[0095] When the transmission 32 is a continuously variable transmission (CVT), a multi-speed transmission, or the like, medical staff can change the speed and torque output by the transmission 32 by adjusting its parameters, thereby changing the swing frequency, swing amplitude, and other parameters of the first load-bearing component 20.

[0096] With the first drive motor 31 and the first carrier 20 connected to the two ends of the transmission 32 respectively, the transmission 32 can be connected to the housing 12 or not connected to the housing 12.

[0097] The transmission 32 is located on the side of the first support member 20 away from the fixing component 21. When the first medicine container is mounted on the first support member 20, the transmission 32 and the first medicine container are located on opposite sides of the first support member 20. The first drive motor 31 is located on the side of the transmission 32 away from the first support member 20, so that the first medicine container can be mounted on the first support member 20 and the mutual interference between the first medicine container and the drive component 30 can be reduced.

[0098] For example, when the housing 12 is provided with a cover, the first drive motor 31 and the transmission 32 are both located on the side of the first support member 20 away from the cover, that is, on the back side of the first support member 20.

[0099] This embodiment provides some specific structures of the driving component 30 so that the driving component 30 can drive the first carrier 20 to swing relative to the housing 12, thereby driving the first medicine container to swing to shake the medicine.

[0100] refer to Figure 3 , Figure 5 In some embodiments, the IV stand 100 further includes a position sensor 40 housed in the housing space 121. The position sensor 40 is connected to the housing 12 and is located on one side of the first support member 20 to detect the position of the first support member 20.

[0101] The position sensor 40 refers to the sensor in the infusion stand 100 used to detect the position of the first support member 20. The position sensor 40 can acquire the position information of the first support member 20 to determine parameters such as the swing amplitude and swing frequency of the first support member 20. The position sensor 40 may include an optical position sensor 40, a Hall effect sensor or other types of sensors.

[0102] The position sensor 40 is connected to the housing 12 by means of adhesive, screw, snap-fit ​​or other methods. There can be one, two or more position sensors 40; when there is only one position sensor 40, the position sensor 40 can be located in the middle of the swing trajectory of the first support member 20.

[0103] The position sensor 40 is located on one side of the first support member 20 to obtain information such as the swing amplitude and swing frequency of the first support member 20. The position sensor 40 can be located on one side of the first support member 20 along the thickness direction Y of the bracket 10, or on one side of the first support member 20 along the width direction X of the bracket 10, or on other sides of the first support member 20.

[0104] For example, there are three position sensors 40. All three position sensors 40 are located on one side of the first support member 20 along the thickness direction Y of the bracket 10. One of the three position sensors 40 is located in the middle of the swing trajectory of the first support member 20, and the other two of the three position sensors 40 are located at the two extreme positions at both ends of the swing trajectory of the first support member 20.

[0105] For example, the position sensor 40 is located on the back of the first carrier 20 and is offset from the transmission 32; further, the position sensor 40 is located above the transmission 32.

[0106] In this embodiment, a position sensor 40 is provided to detect the position of the first support member 20, thereby facilitating the acquisition of parameters such as the swing speed, swing amplitude, and swing frequency of the first support member 20.

[0107] refer to Figures 1 to 4 In some embodiments, the axis of rotational connection between the first carrier 20 and the housing 12 is located below the fixing assembly 21.

[0108] Since the first support member 20 is rotatably connected to the housing 12, there is a rotatable connection between the first support member 20 and the housing 12. The first support member 20 swings back and forth around this part. The axis of rotation between the first support member 20 and the housing 12 is the part of rotation between the first support member 20 and the housing 12, and it is also the axis of rotation of the first support member 20 swinging back and forth.

[0109] When the first support member 20 swings under the drive of the drive assembly 30, the axis is the connection point between the drive assembly 30 and the first support member 20; when the drive assembly 30 includes a first drive motor 31 and a transmission 32, the axis is the connection point between the transmission 32 and the first support member 20.

[0110] The axis of rotational connection between the first support member 20 and the housing 12 is located below the fixing component 21. Since the fixing component 21 is used to fix the first liquid container, this arrangement enables the axis of rotational connection between the first support member 20 and the housing 12 to be located at the lower part of the first liquid container, or completely below the first liquid container. Here, "below" refers to the direction in which the liquid flows out of the first liquid container, or it can refer to the direction of gravity.

[0111] When the first medicine container contains medicine, the axis of rotational connection between the first support member 20 and the housing 12 is located below the first medicine container. Since the medicine enters the infusion tube and eventually enters the patient's body under the action of gravity, the connection position between the infusion tube and the first medicine container is usually located below the first medicine container. Accordingly, with this arrangement, the movement trend of the medicine as the first medicine container swings will also be towards the bottom of the first medicine container, thereby reducing the risk that the first support member 20 will cause the first medicine container to swing, resulting in a large amount of medicine adhering to the inner wall of the first medicine container and causing air to enter the infusion tube with the medicine.

[0112] Meanwhile, under the action of the fixing component 21, the synchronization performance between the first liquid container and the first carrier 20 is high, making it difficult for the first liquid container to swing too much under inertia and for the swing amplitude to be difficult to control. This can further reduce the risk of a large amount of liquid adhering to the inner wall of the first liquid container and causing air to enter the infusion tube with the liquid.

[0113] In this embodiment, the swing axis of the first support member 20 is set below the first medicine container, so that the first support member 20 can not only shake the medicine in the first medicine container evenly, but also reduce the risk of air entering the infusion tube with the medicine.

[0114] refer to Figure 7 In some embodiments, the first support member 20 is further provided with a first suspension assembly 22; the first suspension assembly 22 includes a first slide rail 221 and a first base 222 slidably connected to the first slide rail 221. The first slide rail 221 is connected to the first support member 20 and extends along the height direction of the bracket 10, so that the first base 222 can slide along the height direction of the bracket 10; the first suspension assembly 22 also includes a first pressing member 223 movably connected to the first base 222. The first pressing member 223 can abut against the first support member 20 to fix the relative position of the first base 222 and the first support member 20; the first base 222 is further provided with a first hook 224, which is used to suspend the first liquid medicine container.

[0115] The first suspension assembly 22 refers to the structure on the first carrier 20 used to suspend the first liquid container. The first liquid container can be suspended on the first suspension assembly 22. The first suspension assembly 22 and the fixing assembly 21 work together to better fix the first liquid container on the first carrier 20, so that the first liquid container can swing synchronously with the first carrier 20.

[0116] The first base 222 refers to the structure in the first suspension assembly 22 used to provide a fixed foundation for other structures. The first base 222 can be a plate-shaped structure, a block-shaped structure, or a structural component of other shapes. The material of the first base 222 can include metal, plastic, or other materials.

[0117] The first base 222 is also used to hang the first liquid medicine container, so as to suspend the first liquid medicine container on the first suspension assembly 22, and fix the first liquid medicine container on the first carrier 20 in conjunction with the fixing assembly 21. For example, a first hook 224 can be provided on the first base 222. The first hook 224 is the structure in the first suspension assembly 22 used to suspend the first liquid medicine container. The first hook 224 is provided on the first base 222. The first hook 224 can be connected to the first base 222 by bonding, welding, screwing or other means. The first hook 224 can also be integrally formed with the first base 222. The material of the first hook 224 can include metal, plastic or other materials.

[0118] The first slide rail 221 refers to the structure in the first suspension assembly 22 used to guide the movement of the first base 222. The first slide rail 221 can be a guide shaft, a slide groove, or other shaped structural component. The first slide rail 221 is connected to the first support member 20. The first slide rail 221 can be connected to the first support member 20 by bonding, welding, screwing, or other means. The material of the first slide rail 221 can include metal, plastic, or other materials.

[0119] The first base 222 is slidably connected to the first slide rail 221 so that the first base 222 can move along the guiding direction of the first slide rail 221; the first slide rail 221 extends along the height direction Z of the bracket 10 so that the first base 222 can move along the height direction Z of the bracket 10.

[0120] For example, the first slide rail 221 may include a groove structure, in which a portion of the first base 222 extends into the groove structure and slides along the first slide rail 221; for example, the first slide rail 221 may also include a guide shaft, in which the first base 222 has a through hole, and the guide shaft passes through the through hole so that the first base 222 can move along the first slide rail 221; it is understood that the first slide rail 221 and the first base 222 may also include other structures, and are not limited to the two mentioned above.

[0121] The first pressing member 223 refers to the fixed structure provided on the first base 222. The first pressing member 223 can be a columnar structure, a plate-like structure, or a structure of other shapes. The material of the first pressing member 223 can include plastic, metal, or other materials.

[0122] The first holding member 223 can move relative to the first base 222 to abut against the first support member 20 or detach from the first support member 20. When the first holding member 223 abuts against the first support member 20, the friction between the first holding member 223 and the first support member 20 is large. At this time, the position of the first base 222 can be fixed relative to the first support member 20, and it is difficult to move along the first slide rail 221.

[0123] For example, the first holding member 223 can be a bolt structure. In this case, the first base 222 is provided with a threaded hole, and one end of the first holding member 223 is threadedly engaged with the threaded hole. The first holding member 223 can rotate to move closer to the first bearing member 20 along the axial direction of the threaded hole and abut against the first bearing member 20 to fix the first base 222. The first holding member 223 can also rotate to move away from the first bearing member 20 along the axial direction of the threaded hole and abut against the first bearing member 20.

[0124] For example, the first pressing member 223 can also be a columnar structure with rubber at one end. In this case, the first base 222 is provided with a through hole, and the rubber end of the first pressing member 223 extends into the through hole. The first pressing member 223 can move close to the first support member 20 along the axial direction of the through hole and be fixed in a preset position, so that the rubber abuts against the first support member 20 to fix the first base 222. The first pressing member 223 can also move away from the first support member 20 along the axial direction of the through hole and detach the rubber from the first support member 20.

[0125] During the process of medical staff installing the first liquid medicine container onto the first support member 20, the position of the first base 222 can be adjusted according to the length of the first liquid medicine container. Specifically, medical staff can first move the first holding member 223 away from the first support member 20, and then slide the position of the first base 222. After the position of the first base 222 is determined, the first holding member 223 is made to abut against the first support member 20 to fix the position of the first base 222. Then the first liquid medicine container can be suspended on the first base 222.

[0126] In this embodiment, a first suspension assembly 22 is provided to suspend the first liquid medicine container on the first support member 20; at the same time, the first suspension assembly 22 can adjust the suspension height of the first liquid medicine container, thereby adapting to first liquid medicine containers of different sizes, further expanding the applicability of the infusion stand 100.

[0127] refer to Figures 1 to 3In some embodiments, the infusion stand 100 further includes a second support member 50, which is housed in the accommodating space 121 and is used to support a second medicine container. The second support member 50 is spaced apart from the first support member 20 in a second direction, which is perpendicular to the plane where the swing direction of the first support member 20 is located.

[0128] The second support member 50 refers to the structure in the infusion stand 100 used to support the second medicine container. The second support member 50 can be a plate-shaped structure, a column-shaped structure, or a structure of other shapes. When the second support member 50 is a plate, it can be a square plate, a circular plate, or a plate of other shapes. The material of the second support member 50 can include metal, plastic, or other materials.

[0129] When the IV stand 100 includes the first support member 20, the second support member 50 is provided so that the IV stand 100 can simultaneously support two drug containers. At this time, the two drug containers can contain different drugs. The different drugs in the two different drug containers can form a mixture after being merged into the IV tube, and finally the mixture is injected into the patient's body. Under this condition, both different drug containers can be suspended on the IV stand 100, which is convenient for medical staff to operate.

[0130] The second support member 50 can also be used to hold a spare medicine container, meaning that the first and second medicine containers can hold the same medicine. In this case, after the medicine in the first medicine container on the first support member 20 is used up, the second medicine container on the second support member 50 can be promptly replaced on the first support member 20 for easy operation by medical personnel. It is understandable that the dual-support member configuration of the first and second support members 20 can be applied to other working conditions, not just the two mentioned above.

[0131] The second support member 50 is spaced apart from the first support member 20 in a second direction, and the second direction is perpendicular to the plane containing the swing direction of the first support member 20. The plane containing the swing direction of the first support member 20 is the plane containing the swing trajectory of the first support member 20. When the first support member 20 is rotatably connected to the bottom surface of the housing 12, the second direction is perpendicular to the bottom surface of the housing 12. For example, the plane on the housing 12 connected to the first support member 20 is parallel to the width direction X and height direction Z of the bracket 10, and the plane containing the swing direction of the first support member 20 is also parallel to the width direction X and height direction Z of the bracket 10. In this case, the second direction is the thickness direction Y of the bracket 10.

[0132] By spacing the second support member 50 from the first support member 20, the interference caused by the arrangement of the second support member 50 to the swing of the first support member 20 can be reduced. It is understood that the dimension between the second support member 50 and the first support member 20 in the second direction should be greater than or equal to the dimension of most of the second liquid container, so as to further reduce the interference caused by the arrangement of the second support member 50 to the swing of the first support member 20.

[0133] In this embodiment, a second support member 50 is provided so that both the first support member 20 and the second support member 50 can support the drug container, thereby enabling the infusion stand 100 to support two drug containers. This facilitates medical staff in hanging different drug containers according to their needs and allows the infusion stand 100 to adapt to various working conditions and requirements. The second support member 50 is spaced apart from the first support member 20, reducing the risk of the second support member 50 interfering with the swing of the first support member 20.

[0134] In some embodiments, in the thickness direction Y of the support 10, the cover protrudes outward relative to the housing 12 to form a certain clearance space on the side of the cover facing the housing 12 to accommodate the second support member 50.

[0135] refer to Figure 8 In some embodiments, the second support member 50 is further provided with a second suspension assembly 51; the second suspension assembly 51 includes a second slide rail 511 and a second base 512 slidably connected to the second slide rail 511, the second base 512 is used to hang the second liquid container, the second slide rail 511 is connected to the second support member 50 and extends along the height direction of the bracket 10 so that the second base 512 can slide along the height direction of the bracket 10; the second suspension assembly 51 also includes a second pressing member 513 movably connected to the second base 512, the second pressing member 513 can abut against the second support member 50 to fix the relative position of the second base 512 and the second support member 50; the second base 512 is also provided with a second hook 514, the second hook 514 is used to suspend the second liquid container.

[0136] The second suspension assembly 51 refers to the structure on the second support member 50 used to suspend the second liquid container. The second liquid container and the first liquid container can each contain different liquids or the same liquid. The second liquid container can be suspended on the second suspension assembly 51 to better fix the second liquid container on the second support member 50.

[0137] The second base 512 refers to the structure in the second suspension assembly 51 used to provide a fixed foundation for other structures. The second base 512 can be a plate-shaped structure, a block-shaped structure, or other shaped structural components. The material of the second base 512 can include metal, plastic, or other materials.

[0138] The second base 512 is also used to mount the second liquid container, so as to suspend the second liquid container on the second suspension assembly 51. For example, a second hook 514 may be provided on the second base 512. The second hook 514 is the structure in the second suspension assembly 51 used to suspend the second liquid container. The second hook 514 is provided on the second base 512. The second hook 514 can be connected to the second base 512 by adhesive, welding, screwing or other means. The second hook 514 can also be integrally formed with the second base 512. The material of the second hook 514 may include metal, plastic or other materials.

[0139] The second slide rail 511 refers to the structure in the second suspension assembly 51 used to guide the movement of the second base 512. The second slide rail 511 can be a guide shaft, a slide groove, or other shaped structural component. The second slide rail 511 is connected to the second support member 50. The second slide rail 511 can be connected to the second support member 50 by bonding, welding, screwing, or other means. The material of the second slide rail 511 can include metal, plastic, or other materials.

[0140] The second base 512 is slidably connected to the second slide rail 511 so that the second base 512 can move along the guiding direction of the second slide rail 511; the second slide rail 511 extends along the height direction Z of the bracket 10 so that the second base 512 can move along the height direction Z of the bracket 10.

[0141] For example, the second slide rail 511 may include a groove structure, in which a portion of the second base 512 extends into the groove structure and slides along the second slide rail 511; for example, the second slide rail 511 may also include a guide shaft, in which case a through hole is provided on the second base 512, and the guide shaft passes through the through hole so that the second base 512 can move along the second slide rail 511; it is understood that the second slide rail 511 and the second base 512 may also include other structures, and are not limited to the two mentioned above.

[0142] The second pressing member 513 refers to the fixed structure provided on the second base 512. The second pressing member 513 can be a columnar structure, a plate-like structure, or a structure of other shapes. The material of the second pressing member 513 can include plastic, metal, or other materials.

[0143] The second holding member 513 can move relative to the second base 512 to abut against the second support member 50 or detach from the second support member 50. When the second holding member 513 abuts against the second support member 50, the friction between the second holding member 513 and the second support member 50 is large. At this time, the position of the second base 512 can be fixed relative to the second support member 50 and it is difficult to move along the second slide rail 511.

[0144] For example, the second holding member 513 can be a bolt structure. In this case, the second base 512 is provided with a threaded hole, and one end of the second holding member 513 is threadedly engaged with the threaded hole. The second holding member 513 can rotate to move closer to the second bearing member 50 along the axial direction of the threaded hole and abut against the second bearing member 50 to fix the second base 512. The second holding member 513 can also rotate to move away from the second bearing member 50 along the axial direction of the threaded hole and abut against the second bearing member 50.

[0145] For example, the second holding member 513 can also be a columnar structure with rubber at one end. In this case, the second base 512 is provided with a through hole, and the rubber end of the second holding member 513 extends into the through hole. The second holding member 513 can move along the axial direction of the through hole toward the second bearing member 50 and be fixed in a preset position, so that the rubber abuts against the second bearing member 50 to fix the second base 512. The second holding member 513 can also move along the axial direction of the through hole away from the second bearing member 50 and detach the rubber from the second bearing member 50.

[0146] During the process of medical personnel installing the second medicine container onto the second support member 50, the position of the second base 512 can be adjusted according to the length of the second medicine container. Specifically, medical personnel can first move the second holding member 513 away from the second support member 50, and then slide the position of the second base 512. After the position of the second base 512 is determined, the second holding member 513 is made to abut against the second support member 50 to fix the position of the second base 512, and then the second medicine container can be suspended on the second base 512.

[0147] In this embodiment, a second suspension assembly 51 is provided to suspend the second medicine container on the second support member 50; at the same time, the second suspension assembly 51 can adjust the suspension height of the second medicine container, thereby adapting to second medicine containers of different sizes and further expanding the applicability of the infusion stand 100.

[0148] refer to Figure 9 In some embodiments, the infusion stand 100 further includes a heating assembly 60, which is connected to the housing 12 or to a connection structure between the housing 12 and the base 11; the heating assembly 60 includes a heating element 61; the heating assembly 60 also includes a first clamping member 62, which is located on one side of the heating element 61 and is used to fix the infusion tube and make the infusion tube contact the heating element 61.

[0149] Heating component 60 refers to the structure in the infusion stand 100 used to heat the medicine solution; heating component 60 is connected to housing 12 or to the connection structure between housing 12 and base 11, that is, heating component 60 can be located inside the receiving space 121 and connected to housing 12, or heating component 60 can be located outside the receiving space 121 and connected to the connection structure between housing 12 and base 11.

[0150] Heating element 61 refers to the structure in heating assembly 60 used to provide heat and heat the medicinal liquid. Heating element 61 can be a plate-shaped structure, a tubular structure, or a structure of other shapes. When heating element 61 is a plate-shaped structure, heating element 61 can include a mica heating plate, a ceramic heating plate, or other types of heating plates. Heating element 61 can be located inside the receiving space 121 and connected to the housing 12, or heating element 61 can be located outside the receiving space 121 and connected to the connection structure between the housing 12 and the base 11.

[0151] For example, the heating component 60 may be inside the housing 12 and located below the first carrier 20; for example, the heating component 60 may also be outside the housing 12 to heat the medication before it enters the patient's body.

[0152] The first clamping member 62 refers to the structure in the heating assembly 60 used to clamp the infusion tube connected to the medicine container. The first clamping member 62 may include two strip-shaped or block-shaped structural members arranged relatively apart to clamp the infusion tube between the two. Alternatively, a slot may be provided on the first clamping member to clamp the infusion tube.

[0153] The first clamping member 62 can be located inside the receiving space 121 and connected to the housing 12, or the first clamping member 62 can be located outside the receiving space 121 and connected to the connection structure between the housing 12 and the base 11.

[0154] The first clamping member 62 is located on one side of the heating member 61 so that the infusion tube clamped by the first clamping member 62 can be close to or in contact with the heating member 61, so that the heating member 61 can better heat the liquid medicine flowing through the infusion tube.

[0155] When the ambient temperature of the medicine container is low, or when the medicine in the medicine container requires a certain temperature, the staff can turn on the heating element 61 to heat the medicine flowing through the infusion tube.

[0156] Understandably, the infusion tubing can also be secured to the first clamp 62 to fix the infusion tubing in the absence of needing to heat the medicine solution.

[0157] Furthermore, the heating assembly 60 also includes a pressure cap that is rotatably connected to the first clamping member 62, so that after the infusion tube is clamped on the first clamping member 62, the pressure cap can press against the infusion tube to better fix the infusion tube.

[0158] The heating component 60 provided in this embodiment is used to heat the medication injected into the patient's body through the infusion tube. When different medication containers are supported on the first support member 20 and the second support member 50 respectively, and the different medication containers contain different medications, the heating component 60 should be located below the two different medication containers at the junction of the infusion tubes to heat the mixture of different medications.

[0159] In this embodiment, a heating component 60 is provided to heat the infusion tube, thereby heating the liquid medicine flowing through the infusion tube. This configuration can not only meet the temperature requirements of some liquid medicines, but also increase the temperature of the liquid medicine entering the patient's body when the ambient temperature is low, thereby improving comfort.

[0160] refer to Figure 9 In some embodiments, the heating element 61 and the first clamping element 62 are both connected to the housing 12, and the heating element 61 and the first clamping element 62 are both located below the first support element 20.

[0161] The heating element 61 is connected to the housing 12, that is, the heating element 61 is located inside the housing 12; the heating element 61 can be directly connected to the housing 12, or it can be indirectly connected to the housing 12 through an intermediate structure; the heating element 61 can be connected to the housing 12 by bonding, screwing, snapping or other means.

[0163] For example, the heating element 61 is directly connected to the housing 12, and the first clamping element 62 is connected to the side of the heating element 61 away from the housing 12 to fix the infusion tube on the heating element 61 and facilitate the heating element 61 to heat the medicine in the infusion tube.

[0164] The heating element 61 and the first clamping element 62 are both located below the first bearing element 20. During the process of the medicine entering the infusion tube by gravity and flowing to the patient through the infusion tube, the heating element 61 can heat the flowing medicine.

[0165] Since the medication mainly relies on gravity to flow to the patient through the infusion tube, with the heating element 61 below the first support element 20, the heating element 61 is closer to the patient, resulting in better temperature control of the medication entering the patient's body.

[0166] In this embodiment, the heating element 61 and the first clamping element 62 are both located inside the housing 12 so that the heating component 60 can be accommodated and protected by the housing 12. At the same time, the housing 12 can also prevent the temperature outside the housing 12 from interfering with the temperature of the medicine liquid. The heating element 61 is located below the first support element 20 so that the heating element 61 can be closer to the patient, thereby better controlling the temperature of the medicine liquid entering the patient's body.

[0167] refer to Figure 9 In some embodiments, the infusion stand 100 further includes a liquid level detection component 70, which is connected to the housing 12 or to a connection structure between the housing 12 and the base 11. The liquid level detection component 70 includes a second clamping member 71 for clamping the infusion tube. The liquid level detection component 70 also includes a liquid level detector 72 located on one side of the second clamping member 71.

[0168] The liquid level detection component 70 refers to the structure in the infusion stand 100 used to detect whether there is still medicine in the infusion tube; the liquid level detection component 70 is connected to the housing 12 or to the connection structure between the housing 12 and the base 11. That is, the liquid level detection component 70 can be located inside the receiving space 121 and connected to the housing 12, or the liquid level detection component 70 can be located outside the receiving space 121 and connected to the connection structure between the housing 12 and the base 11.

[0169] The second clamping member 71 refers to the structure in the liquid level detection assembly 70 used to clamp the infusion tube connected to the medicine container. The second clamping member 71 may include two strip-shaped or block-shaped structural members arranged relatively apart to clamp the infusion tube between the two. Alternatively, a slot may be provided on the second clamping member to clamp the infusion tube. The second clamping member 71 may be located inside the receiving space 121 and connected to the housing 12, or it may be located outside the receiving space 121 and connected to the connection structure between the housing 12 and the base 11.

[0170] For example, the second clamping member 71 is connected to the housing 12. The second clamping member 71 can be directly connected to the housing 12 by screwing, welding, bonding or other means. The second clamping member 71 can also be indirectly connected to the housing 12 through an intermediate structure.

[0171] The liquid level detector 72 refers to the device in the liquid level detection assembly 70 used to detect whether there is medicine in the infusion tube. The liquid level detector 72 can be located inside the receiving space 121 and connected to the housing 12, or the liquid level detector 72 can be located outside the receiving space 121 and connected to the connection structure between the housing 12 and the base 11. The liquid level detector 72 is located on one side of the second clamping member 71 so as to detect the medicine in the part of the infusion tube fixed by the second clamping member 71.

[0172] For example, the level detector 72 is connected to the housing 12, and the level detector 72 can be connected to the housing 12 by screwing, snap-fitting or other means.

[0173] The level detector 72 may include a capacitive level gauge, an ultrasonic level gauge, a laser level gauge, or other types of level gauges; for example, the level detector 72 includes a capacitive level gauge comprising two spaced electrodes, with an infusion tube passing between the two electrodes. The capacitance value between the two electrodes differs depending on whether there is medication in the infusion tube or not, thereby determining whether there is still medication in the infusion tube.

[0174] For example, the level detection component 70 may be inside the housing 12 and below the heating component 60; for example, the level detection component 70 may also be outside the housing 12.

[0175] For example, the bottom of the housing 12 is provided with a wire groove for the infusion tube to pass through and to fix the infusion tube.

[0176] Understandably, the first drive motor 31 can stop working in response to the signal from the liquid level detector 72. Specifically, when there is no medicine in the infusion tube, there is also no medicine in the medicine container. At this time, the liquid level detector 72 can detect that there is no medicine in the infusion tube and generate a corresponding signal. The first drive motor 31 can respond to the signal and stop. At this time, the drive assembly 30 no longer drives the first carrier 20 to swing.

[0177] The liquid level detection component 70 provided in this embodiment is used to detect the liquid level of the medicine in the infusion tube. When different medicine containers are supported on the first support member 20 and the second support member 50 respectively, and different medicine containers contain different medicines, the liquid level detection component 70 should be located below the junction of the two different medicine containers in the infusion tube to detect the liquid level of the mixture of different medicines.

[0178] In this embodiment, a liquid level detection component 70 is provided to detect whether there is still medication flowing through the infusion tube, so as to promptly remind the patient and medical staff after the medication injection is completed.

[0179] refer to Figure 9 In some embodiments, the level detection component 70 is housed within the housing space 121.

[0180] The liquid level detection component 70 is housed within the housing space 121, meaning that both the second clamping member 71 and the liquid level detector 72 are located within the housing space 121. The second clamping member 71 can be directly connected to the housing 12 or indirectly connected to the housing 12 through an intermediate structure. The liquid level detector 72 can be directly connected to the housing 12 or indirectly connected to the housing 12 through an intermediate structure.

[0181] For example, the second clamp 71 is directly connected to the housing 12, and the liquid level detector 72 is connected to the second clamp 71 to detect whether there is liquid medicine in the part of the infusion tube that passes through the second clamp 71.

[0182] In this embodiment, the liquid level detection component 70 is located inside the housing 12 so that the housing 12 can accommodate and protect the liquid level detection component 70; at the same time, it is also configured to be further away from the patient so that medical staff have more time to operate after the medicine is used up.

[0183] refer to Figures 1 to 3 , Figure 10 In some embodiments, the bracket 10 further includes an electrically telescopic rod 13, which includes a first rod 131 connected to the base 11 and a second rod 132 connected to the housing 12. The second rod 132 is movably connected to the first rod 131 so that the housing 12 can move closer to or further away from the base 11.

[0184] The electric telescopic rod 13 refers to the structure in the infusion tube used to connect the base 11 and the housing 12. The electric telescopic rod 13 has a telescopic function, thereby adjusting the distance between the housing 12 and the base 11, and thus adjusting the height of the housing 12 above the ground.

[0185] The first rod 131 refers to the structure in the electric telescopic rod 13 that is connected to the base 11. The first rod 131 can be a cylindrical structure or a structure of other shapes; the first rod 131 can be a hollow structure or a solid structure; the first rod 131 is connected to the base 11 by welding, bonding or other means, or the first rod 131 can be integrally formed with the base 11; the material of the first rod 131 can include metal, plastic or other materials, and the material of the first rod 131 can be the same as or different from the material of the base 11.

[0186] The second rod 132 refers to the structure in the electric telescopic rod 13 that is connected to the housing 12. The second rod 132 can be a cylindrical structure or a structure of other shapes; the second rod 132 can be a hollow structure or a solid structure; the second rod 132 is connected to the housing 12 by welding, bonding or other means, or the second rod 132 can be integrally formed with the housing 12; the material of the second rod 132 can include metal, plastic or other materials, and the material of the second rod 132 can be the same as or different from the material of the housing 12.

[0187] One end of the second rod 132 is movably connected to the first rod 131, that is, the second rod 132 can move relative to the first rod 131 along the axial direction of the first rod 131 to drive the housing 12 closer to or away from the base 11; one end of the second rod 132 can be sleeved on one end of the first rod 131, one end of the second rod 132 can be inserted into the first rod 131, and the second rod 132 can also be movably connected to the first rod 131 in other ways.

[0188] When the first rod 131 and the second rod 132 are movably connected, a cylinder, hydraulic cylinder or other structure can be provided on the base 11 to drive the second rod 132 to move relative to the first rod 131.

[0189] In this embodiment, an electric telescopic rod 13 is provided so that medical staff can adjust the height of the housing 12, thereby enabling the infusion stand 100 to adapt to medical staff of different heights and to meet different height requirements.

[0190] refer to Figures 1 to 3 , Figure 10 In some embodiments, one end of the second rod 132 is sleeved on the first rod 131, and the second rod 132 and the first rod 131 are threaded together; the electric telescopic rod 13 also includes a first gear 134 connected to the first rod 131; the electric telescopic rod 13 also includes a second drive motor 133 connected to the base 11, the output end of the second drive motor 133 is connected to a second gear 135, the second gear 135 is driven by the first gear 134, so that the rotation of the second gear 135 can drive the first gear 134 to rotate; the transmission ratio between the second gear 135 and the first gear 134 is greater than 1.

[0191] One end of the second rod 132 is sleeved on the first rod 131, that is, the end of the second rod 132 facing the first rod 131 has a through hole, and the end of the first rod 131 facing the second rod 132 is inserted into the through hole.

[0192] The second rod 132 and the first rod 131 are threaded together. When the second rod 132 is sleeved on the first rod 131, an internal thread can be provided in the through hole of the second rod 132 sleeved on the first rod 131, and an external thread can be provided at the end of the first rod 131 facing the second rod 132, so as to realize the threaded connection between the first rod 131 and the second rod 132.

[0193] When the first rod 131 and the second rod 132 are threadedly connected, a lead screw structure is formed between the first rod 131 and the second rod 132. At this time, the rotation of the first rod 131 can drive the second rod 132 to move along the axial direction of the first rod 131.

[0194] Understandably, because the second rod 132 is connected to the housing 12, and the housing 12 contains other structures and is relatively heavy, rotating the first rod 131 can cause the second rod 132 to move along the axial direction of the first rod 131, but it is not easy to cause the second rod 132 and the housing 12 to rotate. Furthermore, to further prevent the housing 12 from rotating synchronously with the rotation of the first rod 131, the housing 12 can be held by hand during the rotation of the first rod 131 to prevent the housing 12 from rotating.

[0195] The first gear 134 refers to the gear connected to the first rod 131. The first gear 134 can be coaxially connected to the first rod 131 so that the rotation of the first gear 134 can drive the first rod 131 to rotate synchronously. The first gear 134 can be connected to the first rod 131 by bonding, welding, screwing or other means.

[0196] The second drive motor 133 refers to the structure in the electric telescopic rod 13 used to drive the second gear 135 to rotate. The second drive motor 133 can be a servo motor, a stepper motor, or other types of motors. The second drive motor 133 is connected to the base 11. The second drive motor 133 can be connected to the base 11 by gluing, bonding, screwing, snapping, or other means.

[0197] The second gear 135 refers to the gear connected to the second drive motor 133. The second gear 135 is connected to the output end of the second drive motor 133. The second gear 135 can be connected to the output end of the second drive motor 133 by snap-fit, screw-fit or other means.

[0198] The second gear 135 is also connected to the first gear 134 in a transmission connection, so that the rotation of the second gear 135 can drive the first gear 134 to rotate synchronously. The second gear 135 can directly mesh with the first gear 134, or the second gear 135 can be indirectly connected to the first gear 134 in a transmission connection through an intermediate gear (such as an idler gear).

[0199] The transmission ratio between the second gear 135 and the first gear 134 is greater than 1. This means that under the transmission of the second gear 135 and the first gear 134, the rotational speed of the first rod 131 can be less than the rotational speed at the output of the second drive motor 133. Since the output speed of the motor is usually relatively high, this design can reduce the rotational speed of the first rod 131, thereby reducing the lifting speed of the housing 12. Simultaneously, this design also facilitates medical personnel in controlling the height of the housing 12.

[0200] For the base 11, the first gear 134, the second gear 135, and the second drive motor 133 can be directly mounted on the base 11, or they can be mounted inside the base 11. For example, the base 11 has a cavity, and the first gear 134, the second gear 135, and the second drive motor 133 are all located within this cavity. In this case, one end of the first rod 131 also extends into this cavity.

[0201] This embodiment provides a specific structure for the electric telescopic rod 13, which can adjust the height of the housing through the second drive motor 133, gear transmission structure and lead screw structure; the transmission ratio between the second gear 135 and the first gear 134 is greater than 1, so as to reduce the lifting speed of the housing 12, improve the stability of the height adjustment of the housing 12, and facilitate more precise control of the height of the housing 12.

[0202] refer to Figures 1 to 3 In some embodiments, the support also includes a telescopic rod, one end of which is connected to the base 11 and the other end of which is connected to the housing 12. The telescopic rod is used to adjust the distance between the housing 12 and the base 11. And / or the base 11 is provided with casters 14, which have a braking structure. And / or the infusion stand 100 also includes a display 80 connected to the housing 12, which is located outside the receiving space 121. And / or the base 11 is provided with a rechargeable battery.

[0203] The telescopic rod refers to the structure in the infusion tube used to connect the base 11 and the housing 12. The telescopic rod has a telescopic function, thereby adjusting the distance between the housing 12 and the base 11, and thus adjusting the height of the housing 12 above the ground. The telescopic rod can be telescopic through a mechanical structure or an electric telescopic structure. One end of the telescopic rod can be connected to the base 11 by bolts, adhesive, welding or other means. The other end of the telescopic rod can be connected to the housing 12 by bolts, adhesive, welding or other means.

[0204] The caster wheel 14 is a wheel structure located on the base 11 to facilitate the movement of the infusion stand 100 by medical personnel; the caster wheel 14 has a free rotation angle of 360°; the caster wheel 14 can be connected to the base 11 by adhesive, snap-fit ​​or other means.

[0205] The caster wheel 14 has a brake. When the position of the IV stand 100 does not need to be moved, the caster wheel 14 can be fixed by the brake. At this time, the caster wheel 14 cannot rotate, thus fixing the position of the IV stand 100.

[0206] The display 80 refers to the status of the first support member 20 in the infusion stand 100, such as the swing state, swing frequency, swing amplitude, heating status and heating temperature of the heating component 60, and whether there is medicine in the infusion tube. The display 80 can be an OLED display, an LCD display, or other types of display. The display 80 can be connected to the housing 12 by screws, snaps, or other means. The display 80 can be directly connected to the housing 12 or indirectly connected to the housing 12 through an intermediate structure.

[0207] For example, display 80 is connected to the telescopic pole.

[0208] A rechargeable battery refers to the structure in the infusion stand 100 used to power other electronic devices. The rechargeable battery can be a lithium battery or a storage battery. The rechargeable battery can store electrical energy through an external power source and can also power other electronic devices. Among them, other electronic devices may include the first drive motor 31, the heating element 61, the detection 72, the display 80, etc.

[0209] In this embodiment, a telescopic rod is provided to allow medical staff to adjust the height of the housing 12, thereby enabling the IV stand 100 to accommodate medical staff of different heights and to meet different height requirements. Universal wheels 14 are provided on the base 11 to facilitate the movement of the IV stand 100. The universal wheels 14 have a braking structure to fix the position of the IV stand 100 without requiring it to be moved. A display 80 is provided to allow medical staff and patients to view the status of the IV stand 100 and to facilitate their operation. A rechargeable battery is provided so that the IV stand 100 can move synchronously with the patient and can operate normally during movement.

[0210] In some embodiments, the working process of the IV stand 100 provided in this application is described in detail below:

[0211] When it is necessary to shake the liquid in the first medicine container or to heat the liquid in the first medicine container or the liquid in the infusion tube, the user can input control commands (such as shaking commands and / or heating commands) through the display 80 on the infusion stand 100, or input voice control commands (such as shaking commands and / or heating commands) through the voice command module. After the controller in the display 80 receives the control command, it parses the command type of the received control command to determine that the currently received control command is a shaking command and / or heating command.

[0212] When the parsed instruction type indicates a swing instruction, the controller controls the drive assembly 30 of the IV stand 100 to drive the actuator to move according to preset swing parameters, thereby causing the first support member 20 to swing. The preset swing parameters can be pre-stored in the controller's storage unit or set synchronously by the user when inputting the swing instruction; these parameters include, but are not limited to, swing angles (e.g., ±30°, ±45°) and swing speeds (e.g., 30 times / minute, 50 times / minute). The first drive motor 31 in the drive assembly 30, acting as a power conversion component, converts the electrical signal into a power signal suitable for the operation of the first drive motor 31 after receiving the control signal from the controller.

[0213] The first drive motor 31 rotates according to the frequency and quantity of the power signal, and then drives the first carrier 20 and the first liquid container fixed thereon to swing synchronously through the gearbox 32, so as to achieve the shaking and even mixing of the liquid in the first liquid container.

[0214] When the parsed instruction type indicates a heating instruction, the controller controls the heater to heat the liquid in the medicine container or infusion tube by means of a preset target temperature value and the current temperature value detected by the temperature sensor.

[0215] Understandably, the target temperature value can be preset according to the infusion needs (such as human body temperature around 37°C) and stored in the controller, and the user can also adjust it according to the actual situation. Alternatively, the target temperature value can also be set by the user through the operation panel to a suitable infusion temperature, such as around 37°C.

[0216] The control commands input by the user to the display 80 also include liquid level detection commands. When the command type indicates that the control command is a liquid level detection command, or when liquid level detection is automatically triggered under preset conditions, the liquid level detector 72 of the infusion stand 100 is controlled to detect the liquid level status of the medicine in the infusion tube. When the liquid level status of the liquid in the infusion tube is detected to be lower than the preset liquid level status, the warning device of the infusion stand is controlled to issue a warning message.

[0217] The preset fluid level can be pre-set according to clinical needs. For example, the preset fluid level can be set to a level where the remaining fluid in the infusion tubing can only sustain the infusion for 10 minutes. The alarm can use sound alarm, light alarm, or a combination of sound and light: sound alarm can emit a specific frequency prompt tone through a buzzer (such as a "beep" sound at 1-second intervals); light alarm can be achieved through the flashing of LED lights, such as a red LED flashing twice per second; the combined sound and light alarm will activate both the buzzer and LED lights simultaneously to more strongly remind medical staff or caregivers to pay attention to the infusion status.

[0218] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
