Abstract
Description
Technical Field
[0001] This invention relates to the field of infusion technology, specifically to an infusion control device. Background Technology
[0002] Intravenous infusion is a treatment method in which sterile solutions, medications, electrolytes, etc. are directly introduced into the bloodstream through venipuncture.
[0003] During the infusion process, the infusion control device adjusts the infusion flow rate. During the adjustment process, the effective flow cross-sectional area of the infusion tube is changed by squeezing the outside of the infusion tube, thereby achieving the purpose of adjusting the flow rate of the liquid transported inside the infusion tube. Furthermore, when using the infusion control device, considering the needs of different patients and usage environments, the device is equipped with a heating component. Through the heating component and its own heat regulation, the liquid transported inside the infusion tubing is heated to different degrees to achieve a more comfortable infusion effect. However, when the heating component heats the infusion tubing at a higher temperature, the increased temperature reduces the rigidity of the tubing wall and softens the material. When the regulating component applies the same squeezing force to the infusion tubing, the effective flow cross-sectional area of the tubing passively increases, resulting in an actual flow rate higher than the set value. In addition, when transporting liquids with a certain viscosity, the viscosity of the transported liquid decreases as the temperature rises. Under the same flow cross-sectional area, the liquid flow resistance decreases, and the flow rate naturally increases, causing a large deviation in flow rate control and affecting stable infusion use. Therefore, we propose an infusion control device. Summary of the Invention

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. Example 1
[0018] Please see Figures 1-12 The infusion control device shown in the figure includes a controller body 101 for controlling the infusion of the infusion tube 103. The controller body 101 is equipped with a display screen 102. A slot 104 is provided on one side of the controller body 101. A C-shaped mounting cylinder 105 is inserted inside the slot 104. The infusion tube 103 passes through the C-shaped mounting cylinder 105. It should be noted here that the slot 104 and the C-shaped mounting cylinder 105 facilitate the lateral insertion of the infusion tube 103; In addition, the infusion tube 103, the controller body 101 and the display screen 102 are conventional technical components in the technical field of the application. Their structural composition, working principle and control method are known technologies and will not be described in detail here. Also includes: A mounting component is provided on one side of the controller body 101 for mounting during use of the controller body 101; A flow rate control component is disposed inside the C-type mounting cylinder 105 for regulating and controlling the infusion flow rate. A drive component for driving the flow rate regulation component is disposed inside the C-type mounting cylinder 105. In addition, a heating component for heating the infusion tube 103 is provided inside the C-type mounting cylinder 105. An adjustment component for adjusting the heating state is provided on the C-type mounting cylinder 105. A transmission component for synchronously driving the drive component during the adjustment process is provided between the adjustment component and the drive component. It should be noted that during use, the infusion control device, through the cooperation of the flow rate control component, drive component, adjustment component, and transmission component, can flexibly adjust the flow rate of the liquid in the infusion tube 103 and heat the liquid inside the infusion tube 103 to different degrees to achieve a more comfortable infusion effect. In addition, when heating the liquid inside the infusion tube 103, it can adaptively offset the influence of temperature changes on the infusion trend according to the actual heating state, reduce the deviation caused by flow rate control, and facilitate stable infusion use.
[0019] Preferably, the flow rate control component includes a rectangular frame 301 fixed inside the C-shaped mounting cylinder 105, an L-shaped frame 302 fixed on the rectangular frame 301, a first rotating shaft 303 and a second rotating shaft 305 rotatably connected to the L-shaped frame 302 in a symmetrical state, a first pressure plate 304 and a second pressure plate 306 for pressing against the outside of the infusion tube 103 respectively fixed on the first rotating shaft 303 and the second rotating shaft 305, the infusion tube 103 being located between the first pressure plate 304 and the second pressure plate 306, and a mounting motor 307 for driving the first rotating shaft 303 mounted on the L-shaped frame 302; It should be noted that during the process of adjusting the flow rate of the liquid in the infusion tube 103, the first rotating shaft 303 is rotated by the motor 307. The rotation of the first rotating shaft 303 drives the first pressure plate 304 on the first rotating shaft 303 to move towards the outside of the infusion tube 103. During the movement, the first pressure plate 304 pushes against the infusion tube 103, causing the infusion tube 103 to move and come into contact with the second pressure plate 306 on the other side. This results in the first pressure plate 304 and the second pressure plate 306 abutting against both sides of the infusion tube 103. After contact, the motor 307 drives the first pressure plate 304 to rotate, adjusting the pressing effect of the first pressure plate 304 against the infusion tube 103, changing the effective flow cross-sectional area of the infusion tube 103, and thus achieving the purpose of adjusting the flow rate of the liquid inside the infusion tube 103. In addition, the motor 307 is a conventional drive component, and its working principle, power supply method and control method are known technologies in this application, so they will not be described in detail here.
[0020] Preferably, the drive assembly includes a lifting plate 701 disposed inside the rectangular frame 301, a rack 702 fixed on the lifting plate 701, and a gear 703 fixed at one end of the second rotating shaft 305, the gear 703 and the rack 702 being meshed with each other. It should be noted here that: the lifting plate 701 under force is raised and lowered through the transmission component. The movement of the lifting plate 701 drives the rack 702 to move synchronously. During the movement of the rack 702, the second rotating shaft 305 is rotated through the meshing transmission between the rack 702 and the gear 703.
[0021] Preferably, the heating assembly includes multiple sets of fan-shaped plates 401, each set of fan-shaped plates 401 is arranged in a ring array inside the C-shaped mounting cylinder 105, the infusion tube 103 passes through the fan-shaped plates 401, and a mounting groove 402 is provided on the opposite side of each set of fan-shaped plates 401, and a heater 403 for heating is installed inside the mounting groove 402. It should be noted here that: when using infusion, the heaters 403 on each group of sector plates 401 are activated. Through the heating effect of the heaters 403 and the heat conduction effect of the infusion tube 103 itself, the liquid in the infusion process is heated to achieve a more comfortable infusion effect. In addition, in this application, the power of heater 403 remains constant during use, avoiding temperature shocks and resistance wire fatigue caused by frequent power increases and decreases, and extending the life of heater 403. As a conventional heating component, the working principle, power supply method and control method of heater 403 are well known technologies and will not be described in detail here.
[0022] Preferably, the adjustment assembly includes two sets of C-shaped frames 501, which are symmetrically arranged in the axial direction of the C-shaped mounting cylinder 105. Each set of sector plates 401 is located inside the C-shaped frame 501. A connecting rod 502 is provided between the C-shaped frame 501 and the sector plate 401. The two ends of the connecting rod 502 are rotatably connected to the sector plate 401 and the C-shaped frame 501 respectively by pins. The two sets of connecting rods 502 on the sector plate 401 are arranged in a figure-eight shape. A connecting plate 503 is fixed on the C-shaped frame 501. A moving component for moving the connecting plate 503 is provided inside the C-shaped mounting cylinder 105. It should be noted here that: by moving the components, the two sets of connecting plates 503 under force move closer or further apart. During the movement of the two sets of connecting plates 503, the two sets of C-shaped frames 501 move synchronously. During the movement of the two sets of C-shaped frames 501 closer or further apart, through the connecting transmission action of the connecting rods 502 on the C-shaped frames 501, each set of sector plates 401 is forced to move toward or away from the infusion tube 103. Through the movement of each set of sector plates 401, the distance between the heater 403 and the infusion tube 103 is adjusted.
[0023] Preferably, the moving component includes a threaded sleeve 601 fixed on the connecting plate 503, a double-ended lead screw 602 rotatably connected inside the rectangular frame 301, the threads at both ends of the double-ended lead screw 602 are arranged in opposite directions, and the two sets of threaded sleeves 601 are respectively engaged with the two ends of the double-ended lead screw 602. A drive motor 603 for driving the double-ended lead screw 602 is installed inside the rectangular frame 301. Two sets of guide rods 604 are fixed inside the C-shaped mounting cylinder 105, and the two sets of guide rods 604 are symmetrically arranged on both sides of the double-ended lead screw 602. The connecting plate 503 is slidably connected to the two sets of guide rods 604. It should be noted here that: the double-ended lead screw 602 is rotated by the drive motor 603. Since the threads at both ends of the double-ended lead screw 602 are set in opposite directions, during the rotation of the double-ended lead screw 602, the threaded sleeves 601 on the two sets of connecting plates 503 mesh with the two ends of the double-ended lead screw 602 respectively, so that the two sets of connecting plates 503 are subjected to force and move. During the movement of the connecting plates 503, the sliding guidance of the two sets of guide rods 604 causes the two sets of connecting plates 503 to move closer to each other or further away from each other after being subjected to force. In addition, the working principle, power supply method and control method of the drive motor 603 are common technologies in this application and will not be described in detail here.
[0024] Preferably, the transmission assembly includes a threaded tube 801 rotatably connected to the L-shaped frame 302, one end of the threaded tube 801 being fixed to one end of the double-ended lead screw 602, a threaded rod 802 being threadedly engaged on the threaded tube 801, one end of the threaded rod 802 being fixed to the lifting plate 701, and a guide assembly for guiding during the transmission process being provided between the lifting plate 701 and the L-shaped frame 302. It should be noted that when driving the heaters 403 to move closer to each other to improve the heating effect on the liquid inside the infusion tube 103, the rotation of the double-ended lead screw 602 drives the threaded tube 801 to rotate. During the rotation of the threaded tube 801, the threaded tube 801 is subjected to force and moves due to the meshing transmission between the threaded tube 801 and the threaded rod 802 and the connection between the threaded rod 802 and the lifting plate 701. During the movement of the lifting plate 701, the sliding guide effect of the two sets of sleeves 901 and the slide rod 902 causes the lifted plate 701 to move upward after being subjected to force, thereby achieving temperature regulation and driving the drive components at the same time.
[0025] Preferably, the guide assembly includes two sets of sleeves 901 fixed on the L-shaped frame 302. The two sets of sleeves 901 are symmetrically arranged on both sides of the threaded tube 801. A slide rod 902 is slidably connected to the sleeve 901, and one end of the slide rod 902 is fixed to the lifting plate 701. It should be noted here that the movement of the lifting plate 701 after being subjected to force is guided by the sleeve 901 and the slide rod 902.
[0026] Preferably, the mounting assembly includes a U-shaped frame 201 fixed to the controller body 101, the U-shaped frame 201 having a threaded groove 202, and a threaded pin 203 threadedly engaged with the threaded groove 202. It should be noted here that: when installing the controller body 101 onto the infusion stand, during the installation process, the U-shaped frame 201 is pushed toward the rod of the infusion stand. During the pushing process, the rod of the infusion stand is positioned inside the U-shaped frame 201. After pushing, the threaded pin 203 is rotated. During the rotation of the threaded pin 203, through the thread engagement between the threaded pin 203 and the threaded groove 202, one end of the threaded pin 203 abuts against the rod of the infusion stand. Through the abutting and squeezing action, the U-shaped frame 201 is installed and fixed onto the rod of the infusion stand, completing the locking and installation of the controller body 101. After the controller body 101 is installed, the infusion tube 103 is pushed from one side of the controller body 101 into the interior of the C-shaped mounting cylinder 105. During the pushing process, the infusion tube 103 is positioned between the first pressure plate 304, the second pressure plate 306, and each set of sector plates 401. Furthermore, in the technical field of this application, the structure and operating principle of the infusion stand are conventional technical components, and will not be described in detail here.
[0027] In this solution: an infusion control device includes the following steps: During the use of the infusion control device, the controller body 101 is pre-installed on the infusion stand. During installation, the U-shaped bracket 201 is pushed towards the rod of the infusion stand, so that the rod is positioned inside the U-shaped bracket 201. After pushing, the threaded pin 203 is rotated. During rotation, the threaded pin 203 engages with the threaded groove 202, causing one end of the threaded pin 203 to abut against the rod of the infusion stand. Through this pressing action, the U-shaped bracket 201 is fixed to the rod of the infusion stand, completing the installation of the controller body 101. After the controller body 101 is installed, the infusion tube 103 is pushed from one side of the controller body 101 into the C-shaped mounting cylinder 105. During this pushing process, the infusion tube 103 is positioned between the first pressure plate 304, the second pressure plate 306, and each set of sector plates 401. Figure 3 The state; During intravenous infusion, when adjusting the flow rate of the liquid in the infusion tube 103, a motor 307 is installed to rotate the first shaft 303. This rotation causes the first pressure plate 304 on the shaft to move towards the outside of the infusion tube 103. During this movement, the first pressure plate 304 pushes against the infusion tube 103, causing it to move and come into contact with the second pressure plate 306 on the other side. This creates a situation where the first and second pressure plates 304 and 306 respectively abut against both sides of the infusion tube 103. After this contact, the motor 307 rotates the first pressure plate 304, adjusting its pressure on the infusion tube 103. During this process, the second pressure plate 306 remains relatively fixed, altering the effective flow cross-sectional area of the infusion tube 103 to regulate the flow rate of the liquid inside the tube. (See reference...) Figure 11 The status diagram shows that, in addition, when using the infusion, the heaters 403 on each group of sector plates 401 are activated. Through the heating effect of the heaters 403 and the heat conduction effect of the infusion tube 103 itself, the liquid in the infusion process is heated to achieve a more comfortable infusion effect. In addition, during the heating process of the delivered liquid by the heating component, the double-ended lead screw 602 is rotated by the drive motor 603. Since the threads at both ends of the double-ended lead screw 602 are set in opposite directions, during its rotation, the threaded sleeves 601 on the two sets of connecting plates 503 mesh with the ends of the double-ended lead screw 602, causing the two sets of connecting plates 503 to move under force. During this movement, the sliding guidance of the two sets of guide rods 604 causes the two sets of connecting plates 503 to move closer or further apart. This movement of the two sets of connecting plates 503 drives the two sets of C-shaped frames 501 to move synchronously. During this movement, the connecting rods 502 on the C-shaped frames 501 connect and transmit the force, causing each set of sector plates 401 to move towards or away from the infusion tube 103. Figure 12 By moving the fan-shaped plates 401, the distance between the heater 403 and the infusion tube 103 is adjusted. By adjusting the distance, the heating effect of each heater 403 on the liquid transported inside the infusion tube 103 during the heating process is controlled. During this process, the heating state of the heater 403 does not change, allowing for more flexible control of the infusion heating. In the process of adjusting the heating temperature in this way, since the heating power of the heater 403 always remains at the rated power, the temperature shock and resistance wire fatigue caused by frequent power increases and decreases are avoided, thus extending the life of the heater 403. Furthermore, when driving the various sets of heaters 403 to move closer together to improve the heating effect on the liquid inside the infusion tube 103, the rotation of the double-ended lead screw 602 drives the threaded tube 801 to rotate. During the rotation of the threaded tube 801, the threaded tube 801 is subjected to force and moves due to the meshing transmission between the threaded tube 801 and the threaded rod 802, and the connection between the threaded rod 802 and the lifting plate 701. During the movement of the lifting plate 701, the sliding guide effect of the two sets of sleeves 901 and the slide rod 902 causes the lifted plate 701 to move upward. The movement of the lifting plate 701 drives the rack 702 to move synchronously. During the movement of the rack 702, the meshing transmission between the rack 702 and the gear 703 causes the second rotating shaft 305 to rotate. The rotation of the second rotating shaft 305... The second pressure plate 306 is rotated toward the infusion tube 103. The rotation of the second pressure plate 306 further compresses the infusion tube 103. During this process, the first pressure plate 304 does not move. By further compressing the infusion tube 103, the internal flow area of the infusion tube 103 is reduced. This compensates for the decrease in liquid viscosity and softening of the infusion tube 103 caused by enhanced heating, which leads to an automatic increase in flow rate. This counteracts the trend of increased flow rate and reduces the deviation caused by flow rate control, facilitating stable infusion use. When it is necessary to reduce the heating effect on the liquid inside the infusion tube 103, the second pressure plate 306 is rotated and reset at the same time as the heaters 403 move away from the infusion tube 103 through the opposite rotation. This avoids the infusion tube 103 being continuously compressed when the heating effect is reduced, which would cause deviation in the infusion flow rate.
