Abstract
Description
Technical Field
[0001] This invention relates to the field of intravenous infusion technology, specifically to an anti-leakage device and method for intravenous infusion in operating room nursing. Background Technology
[0002] Intravenous infusion is a clinical treatment method in which sterile liquids such as drugs, nutritional solutions, and blood are directly infused into veins through an infusion set. It is widely used in disease treatment, nutritional support, emergency care, and other scenarios. It allows drugs to quickly enter the bloodstream and exert their effects, and can also directly replenish the body's required water, electrolytes, or nutrients.
[0003] Traditional intravenous infusion anti-leakage devices are mostly manually adjustable, making it difficult to precisely control the force. If the clamp is too loose, the needle may shift, or if it is too tight, it may affect the patient's blood circulation. Furthermore, they are not suitable for the different limb sizes of adults and children. During surgery, changes in patient position and equipment vibration can easily cause the clamp to loosen, further increasing the risk of needle shift. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides an anti-leakage device and method for intravenous infusion in operating room care, which solves the problems of uneven clamping force, easy loosening, and difficulty in adapting to different limb sizes in traditional fixation methods, thus affecting the safety of infusion.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an intravenous infusion leak-proof device for operating room nursing, comprising a base, a support mechanism fixedly connected to the top of the base, a first fixing frame fixedly connected to one side of the support mechanism, guide rails symmetrically installed on the inner wall of the first fixing frame, a slider slidably connected to the outer wall of the guide rails, a clamping mechanism fixedly connected to one side of the slider, a control box installed on the top of the clamping mechanism, rotating shafts symmetrically installed inside the control box, a dual-axis motor installed in the center of the control box, rotating rods fixedly connected to both output ends of the dual-axis motor, a second threaded rod provided at one end of the rotating rod, a moving rod threadedly connected to the outer wall of the second threaded rod, a first gear installed on the outer wall of the rotating rod, a second gear installed on the outer wall of the rotating shaft, the first gear and the second gear meshing together, an infusion mechanism installed inside the support mechanism, and a through groove opened inside the slider.
[0006] By adopting the above technical solution, the dual-axis motor drives the first threaded rod to move smoothly along the guide rod, which can precisely adjust the clamping force according to the different limb sizes of patients such as adults and children, avoiding being too loose or too tight. After clamping, the moving rod extends synchronously and abuts against the first fixing frame, forming a dual fixing structure of clamping and limiting. This effectively prevents the clamping from loosening or the needle from shifting due to changes in body position or equipment vibration during surgery, ensuring continuous stability during the infusion process. This solves the problems of uneven clamping force, easy loosening, and difficulty in adapting to different limb sizes in traditional fixing methods, which affect the safety of infusion.
[0007] Preferably, the support mechanism includes a fixed column, a connecting plate is fixedly connected to the outer wall of the fixed column, and a control panel is installed on one side of the connecting plate.
[0008] Preferably, a movable column is slidably connected inside the fixed column, and an electric telescopic rod is installed inside the fixed column, with the output end of the electric telescopic rod fixedly connected to the movable column.
[0009] Preferably, a fixing plate is fixedly connected to the top of the movable column, and hooks are symmetrically fixedly connected to the bottom of the fixing plate.
[0010] Preferably, the clamping mechanism includes a tray, a guide rod is uniformly fixedly connected to the top of the tray, a clamping plate is slidably connected to the outer wall of the guide rod, a second fixing frame is fixedly connected to the outer wall of the tray, and the control box is installed on the top of the second fixing frame.
[0011] Preferably, a fixing rod is symmetrically fixedly connected to the top of the clamping plate, and a first threaded rod is threadedly connected to the inside of the fixing rod, with one end of the first threaded rod fixedly connected to the rotating shaft.
[0012] Preferably, the infusion mechanism includes an infusion bottle, an infusion tube installed inside the infusion bottle, a control valve installed on the outer wall of the infusion tube, and the infusion bottle installed inside the hook.
[0013] Preferably, a needle is installed at one end of the infusion tube, a fixing sticker is installed on the outer wall of one end of the infusion tube, and a Bluetooth module is installed at one end of the inner side of the fixing sticker.
[0014] Preferably, a temperature sensor is uniformly installed on one side of the other end of the fixing sticker, a pressure sensor is uniformly installed on the other side of the other end of the fixing sticker, and a humidity sensor is uniformly installed in the middle of the other end of the fixing sticker.
[0015] Methods for preventing leakage of intravenous infusions in operating room nursing include the following steps:
[0016] S1. The moving column is raised and lowered by an electric telescopic rod, so that the fixed plate and the hook are raised and lowered synchronously. S2. Then, the slider slides along the guide rail, causing the second fixed frame to move synchronously. S3. Simultaneously, the dual-axis motor drives the rotating rod to rotate, which in turn drives the first gear and the second gear to mesh and drive the rotating shaft to rotate synchronously. At the same time, the rotating shaft drives the first threaded rod to engage with the fixed rod, pushing the clamping plate to move towards each other along the guide rod, thus stably clamping the patient's limb. S4. By rotating the rotating rod and driving the second threaded rod to rotate, the moving rod extends forward along the thread and passes through the through groove of the slider, finally abutting against the first fixed frame, thereby limiting and fixing the second fixed frame; S5. Then, insert the needle into the vein, fix the needle with a fixation tape, and open the control valve to control the infusion rate. S6. During the infusion process, the temperature, pressure and humidity sensors inside the fixation patch monitor the temperature, tissue pressure and skin humidity at the puncture site, respectively. The data is transmitted to the control panel in real time via Bluetooth module. The control panel issues an audible and visual alarm, then closes the control valve to stop the infusion, and adjusts the needle position or re-punctures.
[0017] This invention provides a device and method for preventing leakage of intravenous infusions in operating room care. It has the following beneficial effects: 1. This invention uses a dual-axis motor to drive the first threaded rod to link the clamping plate, which moves smoothly along the guide rod. The clamping force can be precisely adjusted according to the different limb sizes of patients such as adults and children, avoiding being too loose or too tight. After clamping, the moving rod extends synchronously and abuts against the first fixing frame, forming a dual fixing structure of clamping and limiting. This effectively prevents the clamping from loosening or the needle from shifting due to changes in body position or equipment vibration during surgery, ensuring continuous stability during the infusion process. It solves the problems of uneven clamping force, easy loosening, and difficulty in adapting to different limb sizes in traditional fixing methods, which affect the safety of infusion.
[0018] 2. This invention uses an electric telescopic rod to drive the moving column to rise and fall, which can quickly adjust the height of the infusion bottle to meet the liquid level requirements of different infusion speeds and surgical positions; the dual-axis motor drives the clamping mechanism to move, which in turn drives the slider to slide along the guide rail and move the clamping mechanism up and down, which can accurately align the patient's infusion site and adapt to various surgical positions such as supine and lateral; the overall adjustment structure does not require cumbersome manual operation.
[0019] 3. This invention is equipped with functions such as clamping and fixing, height adjustment, and position calibration. Combined with a control panel for centralized operation, medical staff do not need to operate multiple parts separately. They can easily complete the entire process of parameter setting, clamping adjustment, and status viewing. At the same time, the various adjustment and fixing mechanisms work together, eliminating the need for repeated manual calibration, reducing preoperative preparation time and intraoperative monitoring pressure, and allowing medical staff to focus more on surgical cooperation.

[0022] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] Please see the appendix Figure 1 - Appendix Figure 7This invention provides an intravenous infusion leak-proof device for operating room nursing, comprising a base 1, a support mechanism fixedly connected to the top of the base 1, a first fixing frame 7 fixedly connected to one side of the support mechanism, guide rails 15 symmetrically installed on the inner wall of the first fixing frame 7, a slider 16 slidably connected to the outer wall of the guide rails 15, a clamping mechanism fixedly connected to one side of the slider 16, a control box 18 installed on the top of the clamping mechanism, a rotating shaft 23 symmetrically installed inside the control box 18, a dual-axis motor 27 installed in the middle of the control box 18, a rotating rod 26 fixedly connected to each of the two output ends of the dual-axis motor 27, a second threaded rod 25 provided at one end of the rotating rod 26, a moving rod 24 threadedly connected to the outer wall of the second threaded rod 25, a first gear 28 installed on the outer wall of the rotating rod 26, a second gear 29 installed on the outer wall of the rotating shaft 23, the first gear 28 and the second gear 29 meshing together, an infusion mechanism installed inside the support mechanism, and a through groove 30 opened inside the slider 16.
[0024] Specifically, the base 1 provides stable support for the device, ensuring no shaking during use in the operating room; the support mechanism is used to adjust the infusion height and position to adapt to different surgical positions; the first fixing frame 7 provides an installation base for the guide rail 15, and the slider 16 slides along the guide rail 15 to drive the clamping mechanism to move up and down, adjusting the height of the clamping part; the through groove 30 adapts to the installation and sliding space of the guide rail 15; the clamping mechanism is used to fix the patient's infusion site, such as the arm, back of the hand, etc., to prevent the needle 13 from shifting due to changes in body position during surgery; the control box 18 is the clamping mechanism. The power and control core of the device is a dual-axis motor 27 that drives the rotating rod 26 to rotate. Through the meshing transmission of the first gear 28 and the second gear 29, the rotating shaft 23 moves synchronously. At the same time, the second threaded rod 25 cooperates with the moving rod 24. The moving rod 24 passes through the through groove 30 and abuts against the second fixing frame 17. After the clamping action is completed, the clamping mechanism is limited to prevent the clamping from loosening due to vibration or slight movement of the limb during the operation. The infusion mechanism is responsible for the delivery of intravenous infusion. Leakage-related sensors are integrated into the fixing patch 12 to monitor the infusion status in real time.
[0025] Please see the appendix Figure 1 - Appendix Figure 5The support mechanism includes a fixed column 3, a connecting plate 2 fixedly connected to the outer wall of the fixed column 3, a control panel 8 installed on one side of the connecting plate 2, a movable column 4 slidably connected inside the fixed column 3, an electric telescopic rod 14 installed inside the fixed column 3, the output end of the electric telescopic rod 14 fixedly connected to the movable column 4, a fixed plate 6 fixedly connected to the top of the movable column 4, and hooks 5 symmetrically fixedly connected to the bottom of the fixed plate 6. The clamping mechanism includes a support plate 21, guide rods 20 uniformly fixedly connected to the top of the support plate 21, a clamping plate 19 slidably connected to the outer wall of the guide rods 20, a second fixed frame 17 fixedly connected to the outer wall of the support plate 21, a control box 18 installed on the top of the second fixed frame 17, and fixed rods 35 symmetrically fixedly connected to the top of the clamping plate 19. A first threaded rod 22 is threadedly connected inside the fixed rod 35, and one end of the first threaded rod 22 is fixedly connected to the rotating shaft 23.
[0026] Specifically, in the support mechanism, the fixed column 3 and the movable column 4 slide together. The extension and retraction of the electric telescopic rod 14 can drive the movable column 4 to rise and fall, thereby adjusting the height of the fixed plate 6 and the hook 5 to achieve liquid level adjustment of the infusion bottle 9, thus meeting the needs of different infusion rates. The connecting plate 2 fixes the control panel 8, which integrates parameter setting, status display, and alarm prompt functions for convenient operation by medical staff. The hook 5 is used to suspend the infusion bottle 9, and the symmetrical design improves the stability of the infusion bottle 9. In the clamping mechanism, the support plate 21 provides support for the patient's limb, and the guide rod 20 ensures that the clamping plate 19 slides smoothly and avoids clamping deviation. The second fixed frame 17 fixes the control box 18 to ensure stable operation of the power mechanism. The rotating shaft 23 drives the first threaded rod 22 to rotate, and through the threaded engagement with the fixed rod 35, drives the clamping plate 19 to move up or down, achieving precise clamping of the patient's limb and adapting to limbs of different thicknesses.
[0027] Please see the appendix Figure 1 , Figure 2 , Figure 6 , Figure 7 The infusion device includes an infusion bottle 9, an infusion tube 10 installed inside the infusion bottle 9, a control valve 11 installed on the outer wall of the infusion tube 10, the infusion bottle 9 installed inside the hook 5, a needle 13 installed at one end of the infusion tube 10, a fixing sticker 12 installed on the outer wall of one end of the infusion tube 10, a Bluetooth module 32 installed at one end of the fixing sticker 12, a temperature sensor 31 evenly installed on one side of the other end of the fixing sticker 12, a pressure sensor 33 evenly installed on the other side of the other end of the fixing sticker 12, and a humidity sensor 34 evenly installed in the middle of the other end of the fixing sticker 12.
[0028] Specifically, the infusion bottle 9 stores the infusion solution and is suspended and fixed by the hook 5. The infusion tube 10 delivers the solution to the needle 13. The control valve 11 can adjust the infusion rate or quickly close in case of leakage to cut off the delivery of the solution. The fixing sticker 12 is pasted around the puncture site of the needle 13 to achieve the dual functions of fixing the needle 13 and preventing leakage monitoring: since leakage will cause abnormal temperature due to drug stimulation, the temperature sensor 31 can monitor the skin temperature at the puncture site in real time. Since leakage will cause tissue swelling and increased pressure, the pressure sensor 33 can detect the local tissue pressure. Since drug leakage will cause local moisture, the humidity sensor 34 can sense the skin humidity. The Bluetooth module 32 transmits the data from each sensor to the control screen 8 in real time to form a leakage monitoring network to ensure that abnormal situations are detected in time.
[0029] Methods for preventing leakage of intravenous infusions in operating room nursing include the following steps: S1. The moving column 4 is raised and lowered by the electric telescopic rod 14, so that the fixed plate 6 and the hook 5 are raised and lowered synchronously. S2. Then, the slider 16 slides along the guide rail 15, causing the second fixed frame 17 to move synchronously. S3. Simultaneously, the dual-axis motor 27 drives the rotating rod 26 to rotate. The rotation of the rotating rod 26 drives the first gear 28 and the second gear 29 to mesh and transmit the transmission, causing the rotating shaft 23 to rotate synchronously. At the same time, the rotating shaft 23 drives the first threaded rod 22 to engage with the fixed rod 35, pushing the clamping plate 19 to move towards each other along the guide rod 20, thus stably clamping the patient's limb. S4. By rotating the rotating rod 26 and driving the second threaded rod 25 to rotate, the moving rod 24 extends forward along the thread and passes through the through groove 30 of the slider 16, and finally abuts against the first fixed frame 7, thereby limiting and fixing the second fixed frame 17. S5. Then, insert the needle 13 into the vein, fix the needle 13 with the fixation tape 12, and open the control valve 11 to control the infusion rate. S6. During the infusion process, the temperature sensor 31, pressure sensor 33, and humidity sensor 34 inside the fixing patch 12 monitor the temperature, tissue pressure, and skin humidity of the puncture site, respectively. The data is transmitted to the control screen 8 in real time via the Bluetooth module 32. The control screen 8 issues an audible and visual alarm, then closes the control valve 11 to stop the infusion, and adjusts the position of the needle 13 or re-punctures.
