Description

Technical Field

[0001] This invention relates to the field of medical device technology, and specifically discloses an intelligent infusion device and an infusion control system. Background Technology

[0002] Intravenous infusion is an indispensable basic treatment method in the modern medical system. As an important route of drug delivery, it is widely used in various medical scenarios such as clinical emergency care, surgical support, chronic disease treatment, and nutritional supplementation. After the drug solution or nutrient solution is precisely prepared and placed in a special infusion bag or bottle, it is injected directly into the patient's vein through a precision-designed infusion system consisting of infusion tubing, drip chamber, regulating valve, and other components. This achieves rapid absorption, distribution, and therapeutic effect of the drug. In areas such as intensive care, emergency resuscitation, surgical anesthesia, tumor chemotherapy, anti-infection treatment, and electrolyte balance regulation, intravenous infusion plays an irreplaceable key role and has become one of the most commonly used treatment technologies in medical institutions worldwide.

[0003] In pediatric patients and those with hepatic or renal insufficiency, precise drug dosage calculations are often required based on weight, body surface area, or severity of illness. This results in single-dose administrations often being smaller than the drug packaging specifications. In such cases, medical staff must manually remove the infusion bottle containing the remaining medication from the infusion device after the set infusion volume has been reached, and then manually install the infusion bottle for the next patient on the infusion stand. This process is cumbersome and increases workload. This method cannot ensure timely stopping when the set infusion volume is accurately reached, which may lead to over-infusion or under-infusion. Existing infusion devices cannot automatically stop and switch when any set infusion volume is reached; they can only switch when the entire bag of infusion is completed. This cannot meet the actual clinical need for half-dose infusions, resulting in drug waste and low operational efficiency. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an intelligent infusion device and an infusion control system to solve the technical problem that existing infusion devices cannot automatically stop infusion and switch to the next infusion task when the medicine does not need to be completely infused and the infusion volume is reached at any set amount.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intelligent infusion device, comprising a support rod, a first motor mounted on the support rod, a first hydraulic rod mounted on the power output shaft of the first motor, a fixed disk fixedly connected to the telescopic end of the first hydraulic rod, a plurality of conical positioning holes for fixing infusion bottles on the fixed disk, an infusion bottle limiting mechanism mounted on the support rod for limiting and fixing the infusion bottles on the fixed disk, an infusion bottle storage mechanism mounted on the support rod for storing infusion bottles that still contain medication after use, an infusion dose detection and setting mechanism mounted on the support rod for non-contact optical counting of droplets in a Mofe's dropper, and an infusion tube fixing mechanism mounted on the infusion bottle limiting mechanism for fixing the infusion tube.

[0006] In this solution, the infusion bottle limiting mechanism securely clamps the infusion bottle on the fixed disc, ensuring stability during lifting and rotation. The infusion tubing fixing mechanism reliably secures the infusion tubing and the puncture needle, effectively preventing infusion interruptions or contamination risks caused by tubing shaking or slippage. After the infusion begins, the infusion dosage detection and setting mechanism performs high-precision, non-contact optical real-time monitoring of the droplets in the Mofe's dropper. Once the set dosage is reached, the infusion bottle, still containing residual medication, is smoothly transferred to the infusion bottle storage mechanism for preservation, avoiding medication waste and environmental pollution. It also provides convenience for subsequent possible bottle refill treatments. Compared with most existing simple infusion stands that have single functions and rely on manual monitoring, this device achieves fully automated processing of multiple functions, including bottle fixing, tubing management, progress monitoring, and residual liquid disposal, from "initial fixing" to "end recycling." This reduces repetitive labor and monitoring pressure on medical staff and effectively avoids medical risks such as human counting errors, forgetting to turn off the flow clamp, or premature needle removal.

[0007] Furthermore, the infusion bottle limiting mechanism includes a sliding frame, which is fixedly connected to the first fixed plate. A slidable sliding block is provided inside the sliding frame. Two first support plates are installed above the sliding block, and a rotating shaft is installed on the two first support plates. A second motor is provided on the side wall of the sliding block, and the power output shaft of the second motor is fixedly connected to the rotating shaft. A clamping and limiting unit for clamping and limiting the infusion bottle is provided on the rotating shaft. A linkage lifting unit for cooperating with the fixed disc is provided on the sliding block.

[0008] In this solution, when the first hydraulic rod drives the fixed disc and the multiple infusion bottles fixed on it to rise and fall as a whole, the sliding block can follow the rise and fall synchronously under the precise guidance of the sliding frame through the linkage lifting unit. This allows the entire clamping and limiting unit installed on the sliding block to always maintain the correct relative position with the infusion bottle, without the need for an additional independent drive unit. This simplifies the mechanical structure, reduces the failure rate, and ensures the stability and safety of the infusion bottle during the height change process.

[0009] Furthermore, the clamping and limiting unit includes a first fixing rod, which is fixedly connected to the rotating shaft. A second hydraulic rod is installed on the first fixing rod, and a first clamping ring that can fit against the outer wall of the infusion bottle is fixedly connected to the telescopic end of the second hydraulic rod. A second fixing rod is fixedly connected to the rotating shaft, and a third fixing rod is provided on the second fixing rod. A second clamping ring that can fit against the outer wall of the infusion bottle is provided on the third fixing rod.

[0010] In this solution, the second hydraulic rod precisely drives the first clamping ring to actively approach and fit against the outer wall of the infusion bottle, thus cooperating with the second clamping ring to efficiently and reliably complete the enveloping clamping of the infusion bottle located on the fixed disc.

[0011] Furthermore, the linkage lifting unit includes a second support plate, the side wall of the fixed disc is provided with an annular groove, the side wall of the sliding block is provided with a second support plate, and an arc-shaped block is installed on the second support plate, the arc-shaped block is slidably disposed in the annular groove.

[0012] In this solution, the linkage lifting unit directly fixes the second support plate to the side wall of the sliding block. The arc-shaped block on the second support plate and the annular groove form a sliding pair. When the first motor drives the fixed disc to rotate, the arc-shaped block only slides circumferentially along the annular groove and does not rotate with the disc, thus maintaining the static posture of the sliding block and the rotating shaft. When the first hydraulic rod drives the fixed disc to lift, the arc-shaped block is forced to lift synchronously due to the upper and lower walls of the annular groove. The sliding block moves within the sliding frame accordingly, realizing full synchronization between the bottle lifting and the clamping and limiting unit. This greatly simplifies the overall structure, reduces manufacturing costs and control complexity, and ensures high consistency and reliability in the lifting positioning and bottle mouth docking process.

[0013] Furthermore, the infusion dose detection and setting mechanism includes a long plate, which is fixedly connected to the lower part of the first fixed plate. The long plate is equipped with a photoelectric sensor for non-contact optical counting of droplets in the Mofeet dropper. The first fixed plate is equipped with a third motor, and the power output shaft of the third motor is fixedly connected to a cam. The first fixed plate is equipped with a first limiting plate, which can cooperate with the cam.

[0014] In this solution, a photoelectric sensor is used to perform non-contact optical counting of droplets in the Mofe's dropper. The counting signal is transmitted to the infusion control system in real time and directly converted into the cumulative infusion volume. No additional sensors such as turbines or weighing are required. When the set dose is reached, the third motor drives the cam to cooperate with the first limit plate to block the infusion tube. The entire process has no mechanical contact with the medicine, eliminating the risk of contamination. By controlling the rotation angle of the third motor, the degree of squeezing of the infusion tube by the cam can be precisely controlled, thereby achieving the adjustment of its flow rate or complete shut-off.

[0015] Furthermore, the infusion bottle storage mechanism includes a fixed frame, on which a fourth motor is mounted. The power output shaft of the fourth motor is fixedly connected to a storage tray. The storage tray has multiple fixed slots for storing infusion bottles containing residual medication. The fixed frame is equipped with a protective cover with a radius consistent with that of the storage tray. The protective cover has a movable opening that allows for the displacement of the clamping and limiting unit. The storage tray is equipped with a secondary protection unit for sealing and protecting the infusion bottles containing residual medication. The secondary protection unit includes several springs. The storage tray has an annular groove. The annular groove door is equipped with a sliding limit ring. Several springs are installed in the annular groove. One end of several springs is fixedly connected to the bottom surface of the storage tray, and the other end of several springs is fixedly connected to the lower end face of the limit ring.

[0016] In this solution, after the clamping and limiting unit places the infusion bottle containing the remaining medication into the fixed slot via the rotating shaft, the fourth motor immediately drives the storage tray to rotate, moving it away from the moving port on the protective cover to isolate it from external contamination. During the transfer process, the infusion bottle limiting mechanism will naturally press the limiting ring down into the ring groove and compress the spring. Once the placement action is completed, the infusion bottle limiting mechanism moves away, and the compressed spring immediately pushes the limiting ring upward to reset, making it tightly fit with the lower end face of the protective cover, forming an effective sealed state. This solves the problem that if the residual medication bottle removed manually is not handled properly, it will be exposed to an unclean environment, stored improperly, or not sealed in time, which can easily cause contamination, deterioration, or confusion of the medication. This may not only lead to the waste of precious medicines, but if it is reused incorrectly, it may also cause serious medical safety problems such as secondary contamination and cross-infection.

[0017] Furthermore, the infusion tube fixing mechanism includes a fixing platform, on which a third hydraulic rod is installed. A second limiting plate is fixedly connected to the telescopic end of the third hydraulic rod. A fourth fitting groove is provided on the second limiting plate. A third limiting plate is fixedly connected to the fixing platform. A fifth fitting groove is provided on the third limiting plate. The fourth fitting groove and the fifth fitting groove communicate to form a bottle stopper puncture needle clamping cavity.

[0018] In this solution, the second limiting plate is moved along the fixed platform by the precise drive of the third hydraulic rod. Its fourth mating groove aligns with the fifth mating groove of the third limiting plate to form a closed cavity, thereby achieving adaptive clamping and fixing of the infusion tube stopper puncture needle. The stopper puncture needle is firmly held in the cavity formed by the fourth and fifth mating grooves, eliminating the risk of blood backflow caused by needle movement. It also eliminates the cumbersome steps of traditional spring clips or double-sided screw adjustment, simplifying the structure and ensuring reliable operation.

[0019] Furthermore, this includes an infusion control module and a nurse terminal; The infusion control module is used to receive the target infusion volume, convert the droplet count into the infused volume in real time, and trigger "clamping tube-saving-bottle change" when the difference is ≤1mL. After completion, it automatically switches to the next bottle. The nurse terminal is used to set the target infusion volume and the initial drug volume of each infusion bottle on the intelligent infusion device.

[0020] In this solution, the infusion control module and the nurse terminal work together. The nurse terminal serves as the infusion metering setting terminal, enabling medical staff to accurately preset the target infusion volume and initial volume of each bottle of medication, providing a precise data starting point for the automated process. The infusion control module acts as the execution and decision-making center, receiving the drop count signal transmitted by the photoelectric sensor in real time and converting it into a cumulative infusion volume. It then compares this volume with the target infusion volume and the initial medication capacity of the infusion bottle on the nurse terminal in real time. Upon receiving the instruction, it automatically triggers a series of actions: "clamping the tube - saving - changing the bottle," achieving automatic switching for unattended operation. This design transforms traditional passive monitoring, manual calculation, and manual operation into proactive quantitative management of the entire process, eliminating risks such as over-infusion, under-infusion, or backflow caused by visual observation errors, human calculation errors, or untimely bottle changes. This greatly improves the safety, accuracy, and nursing efficiency of infusions.

[0021] Furthermore, the infusion control module includes an infusion drop count conversion unit, an instruction receiving and judgment unit, an execution unit, and a queue management unit; The infusion drip rate conversion unit is used to receive the droplet signal from the photoelectric sensor to the Mofeet dropper in real time, and convert the number of drops into the cumulative infusion volume in an instant. When the cumulative volume is close to the target volume and the difference is ≤1 mL, the completion signal is triggered. The instruction receiving and judgment unit is used to receive the target volume of each infusion bottle issued by the nurse terminal and compare it with the initial infusion bottle volume. If the difference is ≤2 mL, it is considered as a whole bottle infusion and is not sealed for storage. If the difference is >2 mL, it is considered as a partial infusion and the bottle is automatically transferred to the infusion bottle storage mechanism. The execution unit is used to control the intelligent infusion device to perform operations such as replacing infusion bottles and collecting and protecting infusion bottles that still contain residual medication after use. The queue management unit is used to automatically load the target quantity of the next bottle after the current bottle is completed and to execute the process in a loop.

[0022] In this solution, the infusion drip rate conversion unit uses photoelectric sensing technology to perform non-contact real-time monitoring of the Mofeet dropper, accurately converting the droplet signal into a cumulative infusion volume. This completely avoids volume errors caused by environmental interference in traditional manual counting or simple timing devices. When the preset target volume (error ≤ 1mL) is about to be reached, subsequent operations are automatically triggered. The instruction receiving and judgment unit intelligently compares the target infusion volume with the initial drug volume in the bottle, automatically determining whether it is a "full bottle infusion" or a "partial infusion," and accordingly deciding whether to initiate a sealing and preservation procedure. This function not only effectively avoids the waste of valuable or special medications but also fundamentally eliminates the safety risks that residual medication may pose. To mitigate the risk of cross-infection, the execution unit responds immediately to the instructions issued by the pre-sequence unit, precisely controlling the mechanical structure to complete a series of actions, including clamping the tubing, safely recovering infusion bottles containing residual fluid, and automatically replacing them with new bottles. The entire process requires no manual intervention, achieving seamless connection and fully closed operation, greatly reducing the labor intensity and operational burden of medical staff. Finally, the queue management unit acts as the command center, ensuring the orderly progress of the entire infusion task. After the current bottle is completed, it can automatically load the parameters of the next bottle and work in a loop, realizing automated pipeline management of multiple bottles of continuous infusion. This not only improves infusion accuracy but also reduces the workload of nurses. The system is simple and reliable.

[0023] Furthermore, the nurse terminal includes a sending unit; The sending unit is used to send infusion dosage information to the infusion control module.

[0024] In this solution, the nurse terminal's built-in sending unit allows nurses to remotely and accurately send preset infusion dosage and initial drug volume information to the infusion control module, changing the traditional mode that requires manual on-site intervention and greatly improving nursing efficiency.

[0025] The working principle and beneficial effects of this solution are as follows: When the infusion begins, the infusion bottle is inverted and placed in the conical positioning hole of the fixed disc. The second motor in the clamping and limiting unit drives the rotating shaft to rotate, moving the first and second clamping rings to both sides of the bottle. The second hydraulic rod pushes the first clamping ring and the fixed second clamping ring to work together to firmly clamp the infusion bottle. The nurse sets the infusion volume through the nurse terminal, and the sending unit sends the infusion dosage information to the infusion control module. During the infusion, the photoelectric sensor optically monitors the droplets in the Mofeet drip chamber, and the infusion drop count conversion unit calculates the cumulative infusion volume in real time. When the infusion volume reaches the target value... When the preset dosage is reached, the execution unit immediately activates the third motor to drive the cam to close the infusion tube. If it is a partial infusion (there is still liquid in the bottle), the execution unit flips the bottle 180° and seals it, transferring it to the fixed slot in the storage tray. If it is a full infusion (the bottle is empty), the clamping and limiting unit is released directly, and then the execution unit drives the rotating drum to switch to the next infusion bottle and continue the infusion. No manual intervention is required throughout the process. This system effectively solves the technical problem that existing infusion devices cannot automatically stop and safely switch to the next infusion bottle after infusing any set amount.

The protective cover 47 coaxially covers the storage tray 45. The radius of the protective cover 47 is the same as the radius of the storage tray 45. The protective cover 47 has a moving port 49. The storage tray 45 is provided with a secondary protection unit, which is used to provide sealing protection for the infusion bottle that temporarily stores residual medicine.

[0036] like Figure 5 and Figure 11As shown, the secondary protection unit includes several springs 50 and a limiting ring 51.

[0038] like Figure 12 As shown in this embodiment, the infusion control system includes an infusion control module 60 and a nurse terminal 65. The infusion control module 60 is integrated on the first fixed plate 7. The infusion control module 60 is used to set the target infusion volume for a single bag of infusion. The nurse terminal 65 is wirelessly connected to the infusion control module 60. The nurse terminal 65 is used by the nurse to send the preset infusion volume to the infusion control module 60.

[0039] The nurse terminal 65 includes a sending unit 66; The sending unit 66 is used to send multiple sets of infusion volume information to the infusion control module 60.

[0040] The infusion control module 60 includes an infusion drop count conversion unit 61, an instruction receiving and judgment unit 62, an execution unit 63, and a queue management unit 64; The infusion drop count conversion unit 61 is used to receive the drop signal of the photoelectric sensor 29 to the Mofeet dropper in real time, and convert the drop count into the cumulative infusion volume in an instant. When the cumulative volume is close to the target volume difference ≤ 1 mL, the completion signal is triggered. The instruction receiving and judgment unit 62 is used to receive the target infusion volume per bottle issued by the nurse terminal 65, and simultaneously judge whether the infusion volume of each infusion bottle set by the nurse terminal 65 on the intelligent infusion device is the same as the initial drug volume of the infusion bottle. The instruction receiving and judgment unit 62 is used to receive and store the target infusion volume per bottle issued by the nurse terminal 65, and simultaneously calculate the difference between the target infusion volume and the initial drug volume of the infusion bottle. When the absolute value of the difference is less than or equal to the preset error threshold, it is determined as "whole bottle infusion", and the intelligent infusion device does not transfer the infusion bottle to the infusion bottle storage mechanism. When the absolute value of the difference is greater than the preset error threshold, it is determined as "partial infusion", and the intelligent infusion device transfers the infusion bottle to the infusion bottle storage mechanism for storage through the infusion bottle limiting mechanism. The preset error threshold is the larger value between ±1% and ±2mL of the initial drug volume, and the absolute value is not less than ±1mL. The execution unit 63 is used to control the intelligent infusion device to perform operations such as changing infusion bottles and collecting and protecting infusion bottles that still contain residual medication after use. The queue management unit 64 is used to automatically load the target volume of the next infusion bottle after the current infusion bottle is completed and to execute the cycle repeatedly.

[0041] In practice: When starting intravenous infusion for the patient, first place all the infusion bottles requiring the infusion into the conical positioning holes 10 of the fixed disc 6 with the bottle openings facing down. Place the first infusion bottle into the conical positioning hole 10 located near the sliding block 12, and then place the remaining infusion bottles clockwise. At this time, start the second motor 16 on the first mounting bracket 15. The second motor 16 drives the rotating shaft 14 to rotate 90° clockwise. During the rotation of the rotating shaft 14, it will drive the first fixed rod 17 and the second fixed rod 21 to rotate. After the first fixed rod 17 and the second fixed rod 21 rotate 90° with the rotating shaft 14, the lower end faces of the first fixed rod 17 and the second fixed rod 21 are in contact with the upper end face of the sliding block 12. At this time, the second motor 16 stops working. After the first fixed rod 17 and the second fixed rod 21 rotate 90° through the rotating shaft 14, the first clamping ring 20 and the second clamping ring 23 are respectively positioned on both sides of the first infusion bottle. The second hydraulic rod 19 is activated to push the first clamping ring 20 to linear displacement and form a cooperative clamping force field with the second clamping ring 23, so as to firmly lock the infusion bottle body on the central axis.

[0042] After the infusion bottle is fixed to the fixed disc 6 by the first clamping ring 20 and the second clamping ring 23, the puncture needle of the infusion tubing to be used by the patient is placed between the second limiting plate 56 and the third limiting plate 57. Then, the third hydraulic rod 55 on the fifth mounting bracket 54 is activated to move the second limiting plate 56 closer to the third limiting plate. The third limiting plate 57 is stably fixed by the fixed platform 53. The third hydraulic rod 55 drives the second limiting plate 56 to gradually clamp and fix the puncture needle of the infusion tubing between the fourth mating groove 58 of the second limiting plate 56 and the fifth mating groove 59 of the third limiting plate 57. When the puncture needle of the infusion tubing is fixed between the second limiting plate 56 and the third limiting plate 57... After that, the infusion tube passes sequentially between the cam 35 and the first limiting plate 36, and then through the long slot 37 opened on the first fixing plate 7. The Mofe's dropper on the infusion tube is placed between the photoelectric sensors 29. Then, the second limiting block 32, which is magnetically connected to the first limiting block 30 by the magnet 31, is removed. At this time, the infusion tube located at the lower end of the Mofe's dropper is placed in the first fitting groove 39. Then, the second limiting block 32 is re-magnetically connected to the magnet 31 in the mounting groove 38 on the first limiting block 30, and the infusion tube is fixed between the first fitting groove 39 and the second fitting groove 40 on the second limiting block 32. At this time, the fixing and limiting of the entire infusion tube is completed.

[0043] After the infusion tubing is fixed, the nurse sets the required infusion dose and initial dose for each infusion bottle through the nurse terminal 65 according to the order in which the infusion bottles to be infused are placed on the fixed disc 6. Then, the sending unit 66 sends the infusion dose and initial dose of the first infusion bottle to the instruction receiving and judging unit 62 of the infusion control module 60 in sequence. At this time, the instruction receiving and judging unit 62 controls the photoelectric sensor 29 to start detecting droplets in the Mofeet dropper.

[0044] After the nurse terminal 65 sets the infusion dose for each infusion bottle, it activates the first hydraulic rod 5 inside the rotating drum 4 located on the support rod 2. The first hydraulic rod 5 drives the fixed disc 6 to move towards the side closer to the support plate 1. During the downward movement of the fixed disc 6, because the second support plate 24 is fixedly connected to the sliding block 12, and the arc-shaped block on the second support plate 24 slides and engages in the annular groove 26 on the fixed disc 6, the fixed disc 6 simultaneously moves the arc-shaped block 25 located in the second groove 27. As the arc-shaped block 25 moves, it simultaneously moves the second support plate 24. When the second support plate 1 moves... During the movement of the support plate 24, the sliding block 12 is simultaneously driven to move downward within the sliding frame 11. At this time, the first fixed rod 17 and the second fixed rod 21 on the sliding block 12 will move downward synchronously. The first fixed rod 17 and the first clamping ring 20 and the second clamping ring 23 on the second fixed rod maintain continuous clamping and fixing of the first infusion bottle. As the fixed disc 6 gradually descends, the bottle opening of the first infusion bottle on the fixed disc 6 will gradually contact the puncture needle on the infusion tube. The first hydraulic rod 5 continues to work and drives the fixed disc to insert the first infusion bottle into the puncture needle, thus completing the action of inserting the puncture needle of the infusion tube into the bottle opening of the first infusion bottle.

[0045] After the puncture needle of the infusion tubing is inserted into the mouth of the first infusion bottle, the medication flows into the Mofe's dropper under the action of gravity, and then flows through the infusion tubing to the intravenous infusion needle that has been fixed to the patient's target vein. During this process, the photoelectric sensor 29 continuously performs non-contact optical monitoring and counting of the droplets in the Mofe's dropper, and transmits the collected drop count signal to the infusion control module 60 in real time. The infusion drop count conversion unit 61 in the infusion control module 60 then processes the signal. The conversion formula of the infusion drop count conversion unit 61 is: cumulative infusion volume (V_total) = number of droplets (n) × calibration coefficient (K), which converts the cumulative drop count into real-time infusion volume.

[0046] During the real-time conversion of infusion drop count by the infusion control module 60, the instruction receiving and judgment unit 62 simultaneously collects the infusion volume calculated in real-time by the infusion control module 60 and compares it in real-time with the infusion volume of the first infusion bottle sent by the sending unit 66. When the instruction receiving and judgment unit 62 finds that the infusion volume calculated by the infusion drop count conversion unit 61 is the same as the infusion volume of the first infusion bottle sent by the sending unit 66, but different from the initial volume of the infusion bottle, it determines that the bottle is partially infused, and the instruction receiving and judgment unit... The disconnection unit 62 then sends an execution signal to the execution unit 63. At this time, the execution unit 63 controls the power output shaft of the third motor 34 on the third mounting bracket 33 to rotate clockwise by 45°. After the power output shaft of the third motor 34 starts to rotate, it synchronously drives the cam 35 to rotate. At this time, the cam 35 gradually squeezes and fixes the infusion tube in the third mating groove 41 on the first limit plate 36. After the third motor 34 drives the cam 35 to complete the 45° rotation, the cam 35 completely squeezes the infusion tube and stops the flow of medicine in the infusion tube.

[0047] After the medication in the infusion tube is stopped by the cam 35, the execution unit 63 controls the first hydraulic rod 5 to drive the fixed disk 6 to rise. As the fixed disk 6 rises, it gradually pulls the first infusion bottle out of the puncture needle on the infusion tube. When the first hydraulic rod 5 reaches the predetermined stroke, the puncture needle is completely removed from the bottle opening. At this time, the second motor 16 drives the rotating shaft 14 to rotate 180° counterclockwise. Since the first clamping ring 20 and the second clamping ring 23 are always in a state of clamping and fixing the first infusion bottle, the rotating shaft 14 simultaneously drives the infusion bottle containing the remaining medication to rotate 180°. During the 180° rotation, the rotating shaft 14 simultaneously drives the infusion bottle to fall into the fixing groove 48 on the storage tray 45 through the moving port 49 on the protective cover 47. The protective cover 47 is fixed by the second fixing plate 46. Mounted above the storage tray 45, as the rotating shaft 14 rotates, the first fixing rod 17 and the second fixing rod 21 on the rotating shaft 14 gradually contact the limiting ring 51 on the storage tray 45. During the movement of the rotating shaft 14, the first fixing rod 17 and the second fixing rod 21 gradually squeeze the limiting ring 51 towards the end closer to the storage tray 45, causing the upper end face of the limiting ring 51 to separate from the lower end face of the protective cover 47. During this process, the limiting ring 51 slides in the annular groove 52 opened on the storage tray 45 while squeezing the spring 50. After the rotating shaft 14 rotates 180° and places the infusion bottle in the fixing groove 48, the second hydraulic rod 19 drives the first clamping ring 20 to move away from the second clamping ring 23, releasing the clamping and fixing state of the infusion bottle located in the fixing groove 48. At this time, the second motor 16 drives the rotating shaft 14 to rotate 90° clockwise to enter the standby state.

[0048] After the second motor 16 drives the rotating shaft 14 to rotate 90° clockwise and enters the standby state, the fourth motor 44 on the fourth mounting bracket 43 drives the storage tray 45 to rotate 60° clockwise, rotating the fixing slot 48, where the infusion bottle is located at the moving port 49, into the protective cover 47. When the second motor 16 drives the rotating shaft 14 to enter the standby state, the compression of the limiting ring 51 ends. At this time, the limiting ring 51 is reset by the spring 50 and fits against the lower end face of the protective cover 47. During this process, the first motor 3 in the first fixed cavity 8 synchronously drives the rotating drum 4 to rotate 60° counterclockwise in the second fixed cavity 9. The rotating drum 4 synchronously drives the first hydraulic rod. The fixed disc 6 on the 5 rotates 60°. After the fixed disc 6 rotates 60°, it moves the second infusion bottle to a position close to the first clamping ring 20 and the second clamping ring 23. After the first motor 3 completes its rotation, the second motor 16 drives the rotating shaft 14 to rotate 90° clockwise, moving the first clamping ring 20 and the second clamping ring to both sides of the second infusion bottle. Then, the second hydraulic rod 19 is activated to clamp and fix the second infusion bottle through the first clamping ring 20. When the first motor 3 rotates 60°, the queue management unit 64 sends an instruction to the instruction receiving and judgment unit 62 to switch the infusion metering information to the second set of infusion metering information.

[0049] When the second infusion bottle begins to be infused, the first hydraulic rod 5 moves the fixed disc 6 downward to insert the puncture needle on the infusion tubing into the infusion bottle. Then, the photoelectric sensor 29 continuously performs non-contact optical monitoring and counting of the droplets in the Mofe's dropper, transmitting the collected drop count signal to the infusion control module 60 in real time. The infusion drop count conversion unit 61 in the infusion control module 60 then processes the signal. At this time, the instruction receiving and judgment unit 62 switches to the second infusion measurement signal sent through the nurse terminal 65. When the instruction receiving and judgment unit 62 collects the infusion volume converted by the infusion drop count conversion unit 61, which is the same as the infusion volume of the second set of infusion bottles sent by the sending unit 66, and is also the same as the initial volume of the infusion bottle, it determines that the bottle is for whole-bottle infusion. At this time, the execution unit 63 controls the third motor 34 to rotate 45° clockwise, driving the cam 35 to squeeze and fix the infusion tube in the third fitting groove 41 of the first limiting plate 36, thereby blocking the infusion tube and preventing air from entering the infusion tube when the infusion bottle is replaced later.

[0050] After the cam 35 stops the infusion tube, the execution unit 63 first controls the second hydraulic rod 19 to move the first clamping ring 20 to end the clamping and fixing of the second infusion bottle. Then, the second motor 16 drives the rotating shaft 14 to rotate 90° counterclockwise to enter the standby state. The queue management unit 64 sends an instruction to the instruction receiving and judgment unit 62 to switch the infusion metering information to the third group of infusion metering information. At this time, the first motor 3 directly drives the fixed disk 6 to rotate 60° counterclockwise to switch the third infusion bottle.
