Description

Technical Field

[0001] This invention relates to the field of infusion device technology, and more particularly to a intravenous nutrition metering infusion device. Background Technology

[0002] Intravenous nutrition infusion is the core method of parenteral nutrition support. It is widely used in critically ill patients, patients in the postoperative recovery period, patients with advanced cancer, and special populations who cannot eat orally. By accurately infusing nutrients such as glucose, amino acids, and fat emulsions, it maintains the stability of the patient's metabolism and vital signs. As a key medical device for realizing this infusion process, the accuracy of intravenous nutrition metering infusion device directly affects the nutritional support effect and the patient's experience. Currently, most existing intravenous nutrition metering infusion devices are designed to be fixed and large-scale, mainly divided into two categories: gravity-type precision infusion sets and electronic infusion pumps. Among them, gravity-type precision infusion sets, although simple in structure and low in cost, require a support for suspension and fixation. Patients need to carry the support or maintain a fixed position when moving, and cannot move freely, resulting in extremely poor portability. Moreover, existing intravenous nutrition metering infusion devices cannot effectively control the infusion volume during infusion, and the total infusion volume is difficult to accurately control, which can easily lead to nutritional imbalance. Especially for special populations such as critically ill patients and newborns, measurement deviations may cause serious clinical risks. Summary of the Invention

[0003] Purpose of the invention: The purpose of this invention is to provide a solution to the problems described in the background art.

[0004] Technical solution: A intravenous nutrition metering infusion device includes a storage box, a sealing cover is fixedly connected to the upper surface of the storage box by a hinge, a placement groove is opened on the upper inner surface of the storage box, a through-type extension opening is opened on the lower inner surface of the placement groove, an infusion bag is placed inside the placement groove, the bottom end of the infusion bag passes through the extension opening, and an electronic meter is detachably connected to the bottom of the bag, and an infusion tube is provided on the lower surface of the electronic meter; The storage box is fixedly connected to both the left and right sides by connecting blocks, and the opposite sides of the two connecting blocks are jointly fixedly connected to a shoulder strap.

[0005] Furthermore, clamps are provided inside the protrusion and at the front and rear of the infusion bag. A groove is provided below the front surface of the storage box. A pulley is symmetrically connected to the front surface of the groove via a rotating shaft. A screw is fixedly connected to the center of the rear surface of each of the two pulleys. The rear ends of the two screws are rotatably connected to the rear surface of the protrusion via a rotating shaft. The outer walls of the two screws are threaded to the inside of the two clamps.

[0006] Furthermore, a transparent plate is embedded in the front surface of the storage box, located in front of the placement slot.

[0007] Furthermore, an inspection cover is fixedly connected to the inner front surface of the groove, a control box is fixedly connected to the front surface of the inspection cover, a control motor is fixedly connected to the inner front surface of the control box, and a second pulley is rotatably connected above the inner front surface of the groove via a rotating shaft. The rear end of the output shaft of the control motor is fixedly connected to the center of the front surface of the second pulley, and a transmission belt is connected to the outer side wall of the second pulley and the outer side walls of the two first pulleys for transmission.

[0008] Furthermore, the protrusion has a limiting groove on its inner left and inner right sides, and a limiting slider is symmetrically slidably connected inside the two limiting grooves. The outer walls of the multiple limiting sliders are fixedly connected to the left and right sides of the two clamping plates, respectively.

[0009] Furthermore, a mobile power supply is fixedly connected inside the control box and below the control motor, and a control module is fixedly connected to the lower inner surface of the control box.

[0010] Furthermore, rubber pads are fixedly connected to the opposite sides of both clamps.

[0011] Furthermore, a magnetic suction plate is embedded in the upper surface of the storage box, and a magnetic suction plate is embedded in the lower surface of the sealing cover. The upper surface of the magnetic suction plate is magnetically connected to the upper surface of the magnetic suction plate.

[0012] Beneficial effects: This invention integrates components such as infusion bags and electronic meters into a storage box, sealing cap, and carrying strap. The overall structure is compact and portable, and patients can wear it with them via the carrying strap. This effectively solves the problems of traditional equipment being bulky and inconvenient to move. The transparent plate allows direct observation of the remaining amount of the infusion bag without opening the sealing cap. Magnetic plates one and two enable the sealing cap to open and close quickly and securely, preventing accidental pop-out during carrying. This not only improves the convenience of mobile use but also provides good protection for the internal components, greatly expanding the patient's range of motion and facilitating postoperative recovery and daily activities. This invention relies on an electronic metering device combined with an automatic clamping and liquid control structure to achieve precise metering and on / off control of nutrient solution infusion. The control motor drives the screw to rotate through pulley two, transmission belt, and pulley one, which drives the clamping plate to smoothly clamp the liquid outlet of the infusion bag. The rubber pad enhances the sealing effect and avoids rigid compression that could damage the bag. The limiting groove and limiting slider ensure stable operation of the clamping plate without deviation, making the liquid blockage more reliable. This invention effectively solves the defects of traditional devices, such as inaccurate metering and inability to control the flow autonomously, thereby improving infusion safety and infusion accuracy. This invention integrates a mobile power supply and a control module into a control box, enabling the entire device to operate independently without an external power source. This further enhances portability and suitability for both outdoor and home use. The control module can automatically control the motor's movement based on the measurement data from the electronic meter, achieving automatic disconnection after quantitative infusion, reducing the burden of manual supervision. Furthermore, the overall structure is rationally designed, combining portability, intelligence, and safety, making it particularly suitable for patients requiring long-term intravenous nutritional support, significantly reducing nursing difficulty and usage risks.

[0015] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] Example like Figures 1-5As shown, an intravenous nutrition metering infusion device is provided, including a storage box 1. A sealing cover 2 is fixedly connected to the upper surface of the storage box 1 by a hinge. A placement groove 3 is opened on the upper surface of the inner side of the storage box 1. A through-hole outlet 4 is opened on the lower surface of the inner side of the placement groove 3. An infusion bag 5 is placed inside the placement groove 3. The bottom end of the infusion bag 5 passes through the outlet 4 and is detachably connected to an electronic meter 6. An infusion tube 7 is provided on the lower surface of the electronic meter 6. Connecting blocks 8 are fixedly connected to the left and right sides of the storage box 1. A shoulder strap 9 is fixedly connected to the opposite sides of the two connecting blocks 8. This device uses a storage box 1 with a sealing cover 2 to store and position the infusion bag 5 through the placement slot 3 inside the storage box 1. The bottom end of the infusion bag 5 passes through the protrusion 4 and is detachably connected to the electronic meter 6. Together with the infusion tubing 7, it achieves stable delivery of nutritional solution. At the same time, it forms a portable structure with the connecting block 8 and the carrying strap 9. This not only effectively protects and neatly stores the infusion bag 5 and the electronic meter 6, preventing the infusion tubing 7 from getting tangled, shaking, or shifting, and ensuring the accurate and stable measurement of the electronic meter 6, but also allows the whole device to be carried by the patient through the carrying strap 9, improving the convenience and comfort of the patient during movement. Moreover, the components are compact and easy to assemble and disassemble. It not only solves the problem of the inconvenience of traditional devices, but also relies on the electronic meter 6 to achieve precise control of the nutritional solution infusion volume, improving the safety and practicality of intravenous nutrition infusion.

[0017] like Figure 1 and Figure 4 As shown, a transparent plate 14 is embedded in the front surface of the storage box 1 and in front of the placement slot 3; The transparent plate 14 allows medical staff and patients to directly observe the remaining liquid level and usage status of the infusion bag 5 in the placement slot 3 without opening the sealing cover 2. This avoids the risk of contamination that may be caused by frequently opening the sealing cover 2, and allows for real-time monitoring of the infusion progress. At the same time, the embedded design makes the overall structure of the storage box 1 flatter and more compact, without affecting portability and storage, further improving the convenience and safety of the device.

[0018] like Figures 5-7 As shown, clamping plates 10 are provided inside the protrusion 4 and in front of and behind the infusion bag 5. A groove 11 is provided below the front surface of the storage box 1. The front surface of the inner part of the groove 11 is symmetrically connected to pulleys 12 via a rotating shaft. Screws 13 are fixedly connected to the center of the rear surface of the two pulleys 12. The rear ends of the two screws 13 are rotatably connected to the rear surface of the inner part of the protrusion 4 via a rotating shaft. The outer walls of the two screws 13 are threaded to the inner parts of the two clamping plates 10. A maintenance cover plate 15 is fixedly connected to the inner front surface of the groove 11. A control box 16 is fixedly connected to the front surface of the maintenance cover plate 15. A control motor 17 is fixedly connected to the inner front surface of the control box 16. A pulley 18 is rotatably connected above the inner front surface of the groove 11 via a rotating shaft. The rear end of the output shaft of the control motor 17 is fixedly connected to the center of the front surface of the pulley 18. A transmission belt 19 is connected to the outer side wall of the pulley 18 and the outer side walls of the two pulleys 12. Inside the outlet 4, clamps 10 are provided on both the front and rear sides of the infusion bag 5. A groove 11 is provided below the front surface of the storage box 1. Pulleys 12 are symmetrically connected to the front side of the groove 11 via a rotating shaft. A screw 13 is fixed to the center of the rear side of each of the two pulleys 12. The rear end of the screw 13 is rotatably connected to the rear side of the outlet 4, and the outer side of the screw 13 is threadedly connected to the inside of the clamp 10. An inspection cover 15 is fixed to the front side of the groove 11. A control box 16 is fixed to the front side of the inspection cover 15. A control motor 17 is fixed to the front side of the control box 16. A second pulley 18 is rotatably connected to the upper front side of the groove 11. The output shaft of the motor 17 is fixed to the pulley 18. The pulley 18 and the two pulleys 12 are connected by a transmission belt 19. When the motor 17 is working, it can drive the pulley 18 and the transmission belt 19 to rotate, so that the two pulleys 12 synchronously drive the screw 13 to rotate, which in turn drives the two clamping plates 10 to move relative to each other. With the measurement signal of the electronic meter 6, the bottom liquid outlet of the infusion bag 5 can be accurately clamped to realize the blocking and opening control of the liquid flow. This ensures the accuracy of the infusion measurement and can reliably close the liquid circuit during movement and carrying, avoiding leakage or accidental infusion, and improving the safety and controllability of the device.

[0019] like Figure 5 and Figure 7 As shown, a limiting groove 20 is provided on the left and right sides of the inside of the protrusion 4. A limiting slider 21 is symmetrically slidably connected inside the two limiting grooves 20. The outer walls of the multiple limiting sliders 21 are fixedly connected to the left and right sides of the two clamping plates 10 respectively. When the clamping plate 10 is driven by the screw 13 to clamp and move, the limiting slider 21 can slide synchronously along the limiting groove 20 to limit and guide the movement trajectory of the clamping plate 10, so as to avoid the clamping plate 10 from deviating, shaking or getting stuck during the movement, and ensure that the two clamping plates 10 are always stably aligned and accurately act on the liquid outlet of the infusion bag 5. Together with the electronic metering device 6, stable and reliable clamping blocking and flow control are achieved, further improving the stability of the device operation and the accuracy of liquid control.

[0020] like Figure 6 and Figure 7As shown, a mobile power supply 22 is fixedly connected inside the control box 16 and below the control motor 17, and a control module 23 is fixedly connected to the lower surface inside the control box 16. Inside the control box 16, a mobile power supply 22 is fixed below the control motor 17, and a control module 23 is fixed on the lower surface. The mobile power supply 22 can provide a stable and independent power supply for the control motor 17, the control module 23, and the electronic meter 6, freeing the device from the limitation of external power supply and making it more suitable for carrying and use when going out. The control module 23 can receive and process the measurement data of the electronic meter 6, and automatically control the start, stop, and direction of the control motor 17 according to the preset infusion volume, thereby driving the clamp 10 to move, realizing the automatic clamping and blocking of the infusion bag 5 and the opening of the flow, making the control of the liquid infusion volume more precise and automated. At the same time, the entire electrical components are integrated into the control box 16, with a compact and regular structure, which further improves the intelligence level and reliability of the portable intravenous nutrition metering infusion device.

[0021] like Figure 7 As shown, rubber pads 24 are fixedly connected to the opposite sides of the two clamping plates 10; Rubber pads 24 are fixedly connected to the opposite sides of the two clamps 10. The rubber pads 24 can increase the contact friction and clamping seal when the clamps 10 clamp the infusion bag 5 at the outlet. This can not only avoid the rigid clamping from squeezing and damaging the infusion bag 5, but also further improve the effect of blocking the flow of liquid and prevent leakage and dripping. At the same time, it plays a buffering and shock absorption role during the clamping process, making the connection between the infusion bag 5 and the clamps 10 more stable when the patient moves with the device. Combined with the accurate measurement of the electronic meter 6, it effectively improves the safety of use and the reliability of liquid control of the entire infusion device.

[0022] like Figure 4 As shown, a magnetic suction plate 25 is embedded in the upper surface of the storage box 1, and a magnetic suction plate 26 is embedded in the lower surface of the sealing cover 2. The upper surface of the magnetic suction plate 25 and the upper surface of the magnetic suction plate 26 are magnetically connected. The magnetic attraction between magnetic plate 25 and magnetic plate 26 allows for quick and secure closure and locking of the sealing cover 2 and storage box 1, preventing accidental opening of the sealing cover 2 during patient transport. The opening and closing operation is simple and requires no additional clips, ensuring both the overall portability and sealing of the device, while also providing reliable protection for the internal infusion bag 5 and related components, thus enhancing the convenience and safety of the device.
