Technical Field
[0001] This invention relates to the field of infusion device technology, specifically to a pediatric nursing infusion heating device. Background Technology
[0002] In pediatric clinical nursing, intravenous infusion therapy is a common intervention. However, children have thin blood vessels and weak thermoregulation, and their requirements for the temperature of infusion solutions, the accuracy of medication, and the safety of infusion are much higher than those for adults. Existing infusion warming devices have many compatibility defects.
[0003] First, most devices use resistance heating and rely on manually set temperatures, without dynamically adjusting to ambient temperature. When ward temperatures fluctuate, temperature differences can easily occur during medication delivery through long tubing. Excessive heat can destroy the medication's efficacy, while insufficient heat can irritate the child's blood vessels. Furthermore, the lack of multi-point temperature monitoring, focusing only on the heated area, fails to cover the initial and output temperatures of the medication, making it difficult to establish closed-loop control and meet the precise temperature control requirements of pediatric medications. Additionally, pediatric medication bottles come in various sizes, and existing devices lack drug identification capabilities, requiring medical staff to manually check labels, which can easily lead to medication errors due to fatigue or distraction. While some devices have a single barcode scanning component, they can only recognize barcodes. The current system cannot read the deep information of the RFID electronic tags on medicine bottles, and the fixed identification components result in low recognition rates for medicine bottles with misaligned tags, making it difficult to build a double safety barrier. The heating area of the device is mostly in the middle or lower section of the infusion tube, which is not conducive to the accumulation and discharge of air bubbles in the tube, and is prone to causing air bubble risks. The microparticles in the medicine solution rely on manual observation, and it is impossible to identify particles caused by contamination or improper compatibility in real time. Moreover, after the medicine solution is exhausted, the tube needs to be manually removed or clamped. Pediatric infusion rates are slow and medical staff have heavy care tasks. Delayed operation can easily cause air embolism, making it difficult to achieve full-process safety monitoring. Therefore, we propose a pediatric nursing infusion heating device. Summary of the Invention

The lower end of the limiting shaft is rotatably connected to the first C-shaped plate through a rotating shaft.
[0011] Preferably, the identification component includes an RFID reader, the lower end of which is fixedly connected to a second C-shaped plate, and the upper end of which is fixedly connected to a bracket. A third C-shaped plate is engaged with the outer side of the bracket, and the lower end of the third C-shaped plate is fixedly connected to a corresponding first C-shaped plate below it. A gear is rotatably connected to the upper end of the bracket via a rotating shaft, and a U-shaped plate is fixedly connected to the upper end of the gear. A first electric telescopic rod is installed on the outer side of the U-shaped plate, and the output shaft of the first electric telescopic rod passes through the U-shaped plate. A slider is fixedly connected to the output shaft of the first electric telescopic rod, and the slider is slidably connected to the inner side of the U-shaped plate. A push rod is fixedly connected to the upper end of the slider.
[0012] Preferably, a guide frame is rotatably connected to the outer side of the push rod, and slide rods are fixedly connected to both sides of the guide frame. The outer side of the slide rod is slidably connected to the bracket, and a miniature camera is installed at the other end of the slide rod. The miniature camera is fixedly connected to the RFID reader via a network cable.
[0013] Preferably, the stopping mechanism includes two symmetrical second electric telescopic rods. The outer shell of the second electric telescopic rod is fixedly connected to a corresponding first C-shaped plate below. The output shafts of the two second electric telescopic rods are fixedly connected to a toothed plate. The two toothed plates mesh with each other on their adjacent sides. The toothed plates have flexible arc plate toothed plates. The two toothed plates are fixedly connected to a connecting block on their opposite sides. A miniature laser particle sensor is installed at the lower end of the connecting block.
[0014] Preferably, an ambient temperature sensor is installed on the outer side of the C-shaped sleeve, a display screen is installed below the ambient temperature sensor on the outer side of the C-shaped sleeve, and a power supply box is installed on the outer side of the C-shaped sleeve, the power supply box being fixedly connected to a semiconductor Peltier via wiring.
[0015] Compared with the prior art, the present invention provides a pediatric nursing infusion warming device, which has the following beneficial effects: 1. The identification component moves around the medicine bottle via a moving component: a miniature camera scans the barcode on the medicine bottle, and an RFID reader reads the electronic tag information. The two transmit data via network cable and perform double verification. At the same time, the verification result is compared with the preset infusion plan to avoid the risk of human error in dispensing or administering the wrong medicine. Compared with the existing manual verification, the accuracy and reliability of identification are significantly improved. The second electric telescopic rod drives the connecting block to move the miniature laser particle sensor close to the infusion tube to monitor the particle content of the medicine in real time. When the number of particles exceeds the built-in baseline, an alarm is immediately triggered. When only air is detected in the infusion tube, the second electric telescopic rod simultaneously drives two locking plates to engage, forming multiple folds to seal the infusion tube. This combination not only solves the problems of untimely manual monitoring of particles and delayed manual tube removal after the medication is exhausted, which can lead to air embolism, but also avoids damage to the infusion tube by using flexible clamping teeth, thus balancing safety and consumable protection. The semiconductor Peltier is installed between the C-shaped sleeve and the partition, with the heating area corresponding to the highest point of the infusion tube. This position is conducive to the accumulation and natural discharge of air bubbles in the infusion tube. Compared with the arbitrary heating position in the existing technology, this further reduces the probability of air bubbles entering the child's body and causing adverse reactions, and is suitable for the physiological characteristics of pediatric children who have thin blood vessels and are more sensitive to air bubbles.
[0016] 2. An ambient temperature sensor monitors the surrounding temperature, and an RFID reader identifies the drug's characteristics and accesses the built-in database. The control system combines this data to automatically set the optimal heating temperature, preventing excessive heat from damaging the drug's efficacy and excessive heat from irritating blood vessels. Simultaneously, multiple temperature sensors within the partition monitor the initial and post-heating temperatures of the medication solution in real time. Closed-loop feedback controls the heating power of the semiconductor Peltier, ensuring a constant output temperature for the medication solution. Compared to existing technologies that rely on manual temperature setting based on experience, this method offers greater temperature control precision and adaptability, better meeting the stringent temperature requirements of pediatric medications. By pressing the first and second push plates, the connecting rod drives the first C-shaped plate and locking strip to slide along the C-shaped sleeve, quickly fixing the device to the bottle opening and infusion tubing without the need for additional tools. Compared to existing technologies that use straps and buckles for fixation, this method improves installation efficiency and is compatible with pediatric medicine bottles of different diameters, offering greater versatility.
[0017] 3. The semiconductor Peltier combines heating and power generation functions: During infusion intervals, the residual medication temperature caused by the high suspension position of the medicine bottle creates a slight temperature difference with the ambient temperature. Based on the Seebeck effect, the Peltier converts this temperature difference into a small amount of electrical energy, which is transmitted to the power supply box for storage. This electrical energy can serve as an auxiliary power source for low-power components. Compared to existing devices without energy recovery, this reduces reliance on external power sources or the frequency of battery replacements, making it particularly suitable for scenarios where infusion stands are frequently moved in pediatric wards. The stop mechanism's clamping plate uses flexible arc-shaped clamping teeth, which can evenly compress the infusion tube to form a seal when engaged. This avoids damage to the infusion tube caused by hard clamping teeth and ensures a tight seal through multiple folds. Compared to existing technologies where hard clamping teeth easily scratch the tube wall and fail to seal properly, this technology balances consumable protection and functional reliability.

[0025] In this embodiment, the verification mechanism 6 includes a moving component 61 for moving the detection bottle, and the verification mechanism 6 also includes an identification component 62 for surrounding the barcode on the detection bottle.
[0026] Specifically, the moving component 61 serves as the power and motion basis for the verification mechanism 6, driving the identification component 62 to make a stable circumferential motion around the outer periphery of the medicine bottle, ensuring that the identification component 62 can cover all areas of the medicine bottle label; the identification component 62 is used to scan the barcode on the bottle while reading the electronic label information of the medicine bottle. Through cooperation with the moving component 61, it realizes comprehensive identification and verification of drug information, providing data support for subsequent automatic setting of heating temperature and verification of infusion plan, and avoiding human medication errors.
[0027] In this embodiment, the moving component 61 includes a support plate 611 fixedly connected to the first C-shaped plate 52. A micro motor 612 is installed at the lower end of the support plate 611, and a first sprocket 613 is rotatably connected to the upper end of the support plate 611 via a rotating shaft. The output shaft of the micro motor 612 is fixedly connected to the first sprocket 613, and a synchronous belt 614 is rotatably connected to the outer side of the first sprocket 613.

[0028] Specifically, the support plate 611 is fixedly connected to the first C-shaped plate 52, providing a stable mounting carrier for the micro motor 612 and the first sprocket 613, ensuring that the entire moving component 61 is linked with the fixed structure of the device; the micro motor 612 serves as the power source for the moving component 61, and its output shaft can drive the first sprocket 613 to rotate, providing power for subsequent transmission; the first sprocket 613 is fixed to the output shaft of the micro motor 612, and can transmit the motor power to the synchronous belt 614, which is a key component for power transmission; the inner side of the synchronous belt 614 is rotatably connected to the first sprocket 613, and the outer side is used to drive the movement of subsequent components. The rubber coating on its inner and outer sides can increase friction, ensuring the stability of the sprocket transmission and the reliability of the connection with subsequent components, respectively, and avoiding slippage during transmission.
[0029] In this embodiment, three second sprockets 615 are rotatably connected to the inner side of the synchronous belt 614. The lower ends of the three second sprockets 615 are rotatably connected to a first C-shaped plate 52 below via a rotating shaft. Two limiting plates are fixedly connected to the outer side of the second sprockets 615.
[0030] Specifically, the three second sprockets 615 cooperate with the first sprocket 613 to provide tension support for the synchronous belt 614, ensuring that the synchronous belt 614 can be stably transmitted and is not easy to fall off. At the same time, it is rotatably connected to the first C-shaped plate 52 through a rotating shaft to ensure its own stability during rotation. The two limiting plates are fixed to the outside of the second sprockets 615, which can limit the two sides of the synchronous belt 614 to prevent the synchronous belt 614 from shifting along the sprocket axis during transmission, further improving the reliability of the synchronous belt 614 transmission.
[0031] In this embodiment, a second C-shaped plate 616 is rotatably connected to the outer side of the synchronous belt 614. The outer side of the second C-shaped plate 616 is slidably connected to the limiting plates of the three second sprockets 615. Four limiting shafts 617 are rotatably connected to the outer side of the second C-shaped plate 616. The lower end of the limiting shaft 617 is rotatably connected to the first C-shaped plate 52 through a rotating shaft.
[0032] Specifically, the second C-shaped plate 616 is rotatably connected to the outer side of the synchronous belt 614, and can move around the outer circumference of the medicine bottle under the drive of the synchronous belt 614. At the same time, it carries the identification component 62, realizing the linkage between the identification component 62 and the synchronous belt 614. The second C-shaped plate 616 is slidably connected to the second sprocket 615 limiting plate. The limiting plate can assist in limiting the movement direction of the second C-shaped plate 616 to prevent it from shaking. One end of the four limiting shafts 617 is rotatably connected to the second C-shaped plate 616, and the other end is rotatably connected to the first C-shaped plate 52. This can further limit the circumferential trajectory of the second C-shaped plate 616, ensuring that it always moves stably in contact with the outer circumference of the medicine bottle without deviation.
[0033] In this embodiment, the identification component 62 includes an RFID reader 621. The lower end of the RFID reader 621 is fixedly connected to the second C-shaped plate 616. The upper end of the RFID reader 621 is fixedly connected to a bracket 622. The outer side of the bracket 622 is engaged with a third C-shaped plate 6211. The lower end of the third C-shaped plate 6211 is fixedly connected to a corresponding first C-shaped plate 52 below.

The upper end of the slider 626 is fixedly connected to a push rod 627.
[0034] Specifically, the RFID reader 621 is fixed to the second C-shaped plate 616 and moves around the second C-shaped plate 616 to read the electronic tag information on the medicine bottle, while simultaneously receiving data transmitted by the miniature camera 6210 for verification; the bracket 622 is fixed to the RFID reader 621, providing mounting support for components such as the gear 623 and the slide bar 629, and its outer side meshes with the third C-shaped plate 6211 to ensure that its own circumferential trajectory conforms to the medicine bottle; the third C-shaped plate 6211 is fixed to the first C-shaped plate 52, serving as the fixed base for the meshing transmission of the bracket 622 and limiting the revolution trajectory of the bracket 622; the gear 623 is rotatably connected to the bracket 622 and moves around the medicine bottle. When the bracket 622 revolves, it meshes with the third C-shaped plate 6211 to achieve rotation, which drives the U-shaped plate 624 to rotate synchronously. The U-shaped plate 624 is fixed to the gear 623, providing an installation position for the first electric telescopic rod 625. The output shaft of the first electric telescopic rod 625 passes through the U-shaped plate 624 and can drive the slider 626 to slide along the U-shaped plate 624 to achieve position adjustment. The slider 626 is fixed and slidably connected to the output shaft of the electric telescopic rod inside the U-shaped plate 624, which can drive the push rod 627 to move. The push rod 627 is fixed to the slider 626 and is used to push the guide frame 628 to transmit the adjustment force of the slider 626, thereby realizing the position adjustment of the miniature camera 6210.

[0037] In this embodiment, the stopping mechanism 7 includes two symmetrical second electric telescopic rods 71. The outer shell of the second electric telescopic rod 71 is fixedly connected to a corresponding first C-shaped plate 52 below. The output shafts of the two second electric telescopic rods 71 are fixedly connected to a toothed plate 72. The two toothed plates 72 mesh with each other on the side that is close to each other. The toothed plates 72 have flexible arc plate toothed plates. The two toothed plates 72 are fixedly connected to a connecting block 73 on the side that is far apart from each other. A miniature laser particle sensor 74 is installed at the lower end of the connecting block 73.
[0038] Specifically, the outer shells of the two second electric telescopic rods 71 are fixed to the first C-shaped plate 52, serving as the power source for the stopping mechanism 7. They can drive the toothed plate 72 to move and close the infusion tube, while simultaneously driving the connecting block 73 to adjust the monitoring position of the micro laser particle sensor 74. The toothed plate 72 is fixed to the output shaft of the electric telescopic rod. The two toothed plates 72 can squeeze the infusion tube through meshing. Its flexible arc plate teeth can protect the infusion tube from damage during squeezing, while forming multiple folds to completely block the pipeline and prevent air embolism. The connecting block 73 is fixed to the toothed plate 72 and is used to connect the toothed plate 72 and the micro laser particle sensor 74, realizing the linkage between the sensor and the toothed plate 72. The micro laser particle sensor 74 is installed at the lower end of the connecting block 73 and can perform real-time particle monitoring of the liquid flowing through the infusion tube to determine whether the liquid is contaminated or has compatibility issues. It can also monitor whether the liquid is about to run out, providing a trigger signal for the toothed plate 72 to close the infusion tube.
[0039] In this embodiment, an ambient temperature sensor 3 is installed on the outside of the C-shaped sleeve 1, a display screen is installed below the ambient temperature sensor 3 on the outside of the C-shaped sleeve 1, and a power supply box 4 is installed on the outside of the C-shaped sleeve 1. The power supply box 4 is fixedly connected to the semiconductor Peltier 9 through a circuit.
[0040] Specifically, the ambient temperature sensor 3 is installed on the outside of the C-shaped sleeve 1 to monitor the ambient temperature around the device in real time, providing environmental data reference for the control system to set the optimal heating temperature according to the characteristics of the drug; the display screen is installed below the ambient temperature sensor 3 to simultaneously display the initial temperature of the drug solution, the temperature of the solution after heating, the ambient temperature, and the target heating temperature, making it convenient for medical staff to view the temperature data intuitively; the power supply box 4 is installed on the outside of the C-shaped sleeve 1 to store electrical energy and simultaneously power the semiconductor Pelta 9 through the circuit to ensure its heating function. In addition, it can also receive the weak electrical energy converted by the semiconductor Pelta 9 based on the Seebeck effect during the infusion interval, providing auxiliary power supply for the low-power components of the device (such as the temperature sensor, ambient temperature sensor 3, and display screen); the circuit connecting the power supply box 4 and the semiconductor Pelta 9 is the channel for power transmission, ensuring the power exchange between the power supply box 4 and the semiconductor Pelta 9.
[0041] Working principle: When using the device, first hang the medicine bottle on the infusion stand according to the specifications and complete the routine air venting operation. Then, position and fix the device: move the C-shaped sleeve 1 to the position of the bottle mouth and the infusion tube connected below at the lower end of the medicine bottle. Utilize the opening characteristics of the C-shaped sleeve 1 to wrap around the bottle mouth and the infusion tube from the side. Then, press the second push plate 8 and the first push plate 53 simultaneously with your fingers. After the first push plate 53 is subjected to force, it drives the two first C-shaped plates 52 to move synchronously through the connecting rod 51. At this time, the first C-shaped plates 52 slide in an arc along the sliding groove on the inner side of the C-shaped sleeve 1 through the end-fixed locking strip 54 until the two first C-shaped plates 52 cooperate with the C-shaped sleeve 1 to tightly lock and wrap the medicine outlet and the connected infusion tube, thus fixing the device to the medicine bottle and the infusion tube. During this process, the angle between the first push plate 53 and the second push plate 8 never exceeds 90 degrees to ensure sufficient space for hand operation. After the device is fixed, the drug solution heating and temperature control process is initiated: The semiconductor Pelta Patches 9 is activated, and the heat released by it heats the cavity between the C-shaped sleeve 1 and the partition 2. The heat is evenly transferred to the drug solution and infusion tubing inside through the partition 2, so that the liquid is heated to the target temperature before entering the long infusion tubing. This design allows the drug solution to reach dynamic equilibrium with the ambient temperature for a longer time while flowing through the tubing, resulting in less temperature fluctuation when it finally reaches the patient's body. At the same time, multiple temperature sensors in the cavity of the partition 2 monitor the initial temperature of the drug solution before entering the heating area and the final liquid temperature after heating, transmitting the temperature data to the control system in real time. The control system displays the real-time liquid temperature, target temperature, and ambient temperature monitored by the ambient temperature sensor 3 on the display screen, and performs closed-loop feedback control of the heating power of the semiconductor Pelta Patches 9 based on the temperature data to ensure a constant output temperature of the drug solution. In addition, the heating position of the semiconductor Pelta Patches 9 is located at the highest point of the infusion tubing, which is conducive to the accumulation and expulsion of air bubbles in the infusion tubing, forming a superior anti-bubble design compared to existing devices. Then, the micro motor 612 at the lower end of the support plate 611 is activated. The output shaft of the micro motor 612 drives the first sprocket 613 to rotate. The first sprocket 613 drives the three second sprockets 615 to rotate through the synchronous belt 614. Under the limit of the three second sprockets 615, the synchronous belt 614 forms a friction transmission with the second C-shaped plate 616 through the outer rubber coating. With the clamping of the four limit shafts 617, the second C-shaped plate 616 makes a stable circumferential rotation around the outer periphery of the medicine bottle. When the second C-shaped plate 616 rotates, it drives the RFID reader 621 fixedly connected to it and the bracket 622 at the upper end to rotate synchronously. The outer side of the bracket 622 meshes with the third C-shaped plate 6211 fixed on the first C-shaped plate 52 to ensure that the rotation trajectory fits the medicine bottle. At the same time, when the gear 623 connected to the upper end of the bracket 622 rotates with the bracket 622, its teeth continuously mesh with the inner tooth groove of the third C-shaped plate 6211, thereby driving the gear 623 to rotate around the bracket 622 as the axis. The gear 623 then drives the upper U-shaped plate 624 to rotate synchronously. Based on the actual diameter of the medicine bottle, the first electric telescopic rod 625 on the outer side of the U-shaped plate 624 is activated. Its output shaft passes through the U-shaped plate 624 and drives the slider 626 to slide along the slide groove on the inner side of the U-shaped plate 624. The slider 626 drives the push rod 627 at the upper end to adjust its position. The push rod 627 pushes the slide rods 629 on both sides through the guide frame 628 rotatably connected on the outer side. The slide rods 629 move in a straight line along the sliding hole of the bracket 622, and finally drive the miniature camera 6210 at the end of the slide rod 629 to approach the label area of the medicine bottle. The miniature camera 6210, through its own movement in conjunction with the revolution and rotation of the gear 623, completely scans the barcode information on the medicine bottle. At the same time, the RFID reader 621 reads the electronic tag information on the medicine bottle. The two transmit data through a network cable and perform double verification. The control system calls the built-in database based on the verified drug characteristics and automatically sets the optimal heating temperature in conjunction with the monitoring data of the ambient temperature sensor 3 to avoid human error. It also compares the temperature with the preset infusion plan to form an additional medication safety barrier, ensuring that the temperature of the medicine reaches the patient's body after flowing through long-distance tubing. Throughout the entire drug infusion process, the stop mechanism 7 is activated for real-time monitoring and safety control: In the initial state, the two second electric telescopic rods 71 drive the connecting block 73 and the lower micro laser particle sensor 74 to move to the preset monitoring position outside the infusion tube, ensuring that the distance between the sensor and the infusion tube is constant to guarantee monitoring accuracy; the micro laser particle sensor 74 performs real-time particle monitoring of the drug flowing through the infusion tube, and the control system has built-in particle content baselines for different types of drug solutions. When an abnormal increase in the number of particles is detected, an alarm is immediately issued to indicate that there may be incompatibility issues or contamination risks in the drug solution. When the micro laser particle sensor 74 detects that there is no medicine flowing in the infusion tube and only air, and determines that the medicine is about to run out, the control system immediately activates the two second electric telescopic rods 71. Their output shafts drive the corresponding toothed plates 72 to move towards each other, so that the flexible arc plate teeth on the side of the two toothed plates 72 that are close to each other mesh with each other. The flexible arc plate teeth squeeze the tube wall evenly from both sides of the infusion tube, forming multiple tight folds on the outside of the infusion tube, thereby completely blocking the tube before the liquid runs out, effectively preventing air from entering the patient's body, and eliminating the need for medical staff to be on duty at all times to prevent the risk of air embolism. In addition, the device has an energy recovery function when there is no need to heat the medicine during the infusion interval: because the medicine bottle is suspended at a high position, the temperature of the residual medicine is slightly different from the ambient temperature. The semiconductor Peltier 9 converts this temperature difference into a small amount of electrical energy based on the Seebeck effect. The electrical energy is transmitted to the battery in the power supply box 4 through the line for storage. Although the stored power is limited, it can serve as an auxiliary power source for the low-power components of the device, reflecting the ultimate energy utilization concept.
