Description

Technical Field

[0001] The present invention relates to the technical field of infusion monitoring, and in particular to an intelligent monitoring device for children's infusion. Background Art

[0002] Children's infusion is mainly through venous puncture, which directly injects the drug into the child's veins, so that the drug can quickly and accurately enter the blood circulation, thereby quickly exerting its efficacy, and is used to treat diseases or replenish the nutrients needed by the body. During the infusion, the infusion bottle containing the required medicine needs to be hung on the infusion stand, and then the infusion tube is connected to the infusion bottle, and then the puncture site on the back of the child's hand is disinfected. After disinfection, the puncture needle is inserted into the vein on the back of the child's hand. Once blood is seen returning, it means that the puncture is successful. At this time, quickly use tape to properly fix the needle to prevent displacement. Finally, slowly open the flow adjustment switch on the infusion tube to allow the medicine to slowly flow into the child's body at an appropriate flow rate to achieve treatment of the child.

[0003] During the infusion of children, on the one hand, children are lively and active by nature and it is difficult for them to wait quietly for a long time. On the other hand, the puncture needle is left in the vein on the back of the hand during infusion, which inevitably brings a certain foreign body sensation and soreness and discomfort, which will induce children to move their hands frequently and unconsciously. Once the hands move randomly, the needle tip of the puncture needle is very likely to shift in the vein. After the needle tip shifts, the infusion liquid cannot flow smoothly along the vein into the body, but instead leaks into the gaps between the surrounding tissues, causing an obvious lump to quickly swell up at the puncture site. If medical staff or parents fail to detect the bulging phenomenon in time, as the leaked liquid continues to accumulate and time passes quietly, it will further aggravate the pressure and damage to the local tissues of the child's hand, which will not only prolong the pain of the child, but may even cause a series of subsequent complications such as local inflammation, phlebitis, etc., threatening the safety of infusion. Therefore, the present application provides an intelligent monitoring device for children's infusion to meet the needs. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an intelligent monitoring device for children's infusion to solve the problem that children's hands are difficult to stabilize and easily bulge during infusion.

[0007] Optionally, the surface of the ball head is inlaid with a second sensing element, the second sensing element is located below the first sensing element, the pressing block is pressed on the second sensing element, an indicator light is inlaid on the side of the support seat, and the second sensing element is electrically connected to the indicator light and the battery pack.

[0008] Optionally, a plurality of rubber support columns are fixed on the top of the bottom plate, a plurality of circular holes are opened at the bottom of the support seat, and the tops of the rubber support columns are inserted into the circular holes and fit with the tops of the inner walls of the circular holes.

[0009] Optionally, the top of the rubber support column is a hemispherical portion.

[0010] Optionally, the slider is in an isosceles trapezoidal shape, and the shape of the slide groove matches the shape of the slider.

[0011] Optionally, the thickness of the spring sheet gradually decreases from top to bottom.

[0012] Optionally, inclined surfaces are provided on opposite sides of the spring sheet, and the width of the top of the spring sheet is greater than the width of the bottom of the spring sheet.

[0013] Optionally, the center of the arc strip is located on the central axis of the ball head.

[0014] Optionally, an inclined guiding surface is provided at the bottom of the arc-shaped strip, and the inclined guiding surface is used for guiding the ball head when it is inserted into the groove.

[0015] Optionally, the ball head, the sliding block and the arc-shaped bar are all hollow.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by setting up the sensing element 1 and the pressure block, the child's hand is placed on the support seat, and after being moderately restrained by the strap 1 and the elastic band, the hand is ensured to be relatively fixed. At the same time, the strap 2 is attached to the injection site and connected to the connecting piece on the slider. Once the injection site has a bulge due to the displacement of the needle, the thrust generated by the bulge will be transmitted through the strap 2, driving the pressure block to move upward, and then pressing the sensing element 1. At this time, the buzzer is triggered to sound an alarm, which reminds the child of the bulge in a conspicuous and timely manner, so that medical staff can rush to deal with the bulge properly.

[0018] By setting the spring piece, the thickness of the spring piece decreases from top to bottom, and with the inclined surface design, the width of the spring piece also decreases from top to bottom. The elastic force in the bottom area of ​​the spring piece is relatively weak. When bulging occurs, the slider can drive the arc bar at the bottom of the spring piece to lift upward steadily and smoothly. In this process, the bottom of the spring piece can be flexibly deformed due to the shape of the spring piece itself, which greatly reduces the resistance encountered by the arc bar moving upward, making the upward movement of the pressure block lighter and more labor-saving, thereby improving the detection accuracy of the bulging phenomenon.

[0019] By setting up the second sensing element, after the child's hand is restrained on the support seat, when the child's hand shakes slightly, it can drive the pressure block to separate from the second sensing element. After separation, the indicator light comes on, informing the child's hand that the hand is in an unstable shaking state at the moment, so that the caregiver or parent can detect and intervene in time to avoid excessive movement of the child's hand, greatly reducing the risk of needle displacement caused by hand movement and then causing bulge.

[0020] By setting up a rubber support column, the rubber support column is used to support the support base to prevent the support base from shaking randomly and ensure the horizontal state of the support base. When the child's hand shakes, the rubber support column is deformed by the shaking force and can still provide resistance to the shaking of the support base, thereby effectively preventing the child's hand from shaking and further preventing the occurrence of bulges.

[0021] By setting the guide surface, the arc strip is stuck in the position of the ball head below the center of the circle with the help of the elastic force of the spring piece. When the infusion is completed, it is only necessary to pull the support seat upwards to separate the ball head from the arc strip, thereby exposing the arc strip part, which is convenient for medical staff to disinfect. When the disinfection process is completed and the support seat is reinstalled, it is only necessary to align the circular groove at the bottom of the support seat with the ball head, and then press the support seat. The top of the ball head will squeeze the guide surface of the arc strip, so that the arc strip drives the spring piece to deform, until the ball head fits with the inner wall of the groove. The arc strip is stuck at the ball head again under the elastic force of the spring piece, so as to realize the connection between the support seat and the bottom plate. The separation and connection process of the support seat and the ball head becomes simple and convenient, thereby facilitating daily disinfection and maintenance work.

After the child's hand is placed on the support seat 2, the other end of the strap 6 is passed over the child's wrist and adhered to the other side of the support seat 2 through Velcro. The strap 6 is pressed on the child's wrist to achieve the restraint of the child's wrist. A curved surface 8 is provided at the end of the support seat 2, and an elastic band 9 is fixed on the curved surface 8. After the child's hand is placed on the support seat 2, the finger is inserted between the elastic band 9 and the curved surface 8, and the elastic force of the elastic band 9 is used to achieve the restraint of the child's finger. A detection mechanism 12 is provided inside the support seat 2.

[0040] The detection mechanism 12 includes a ball head 13 fixed to the top of the base plate 1, a circular groove 14 is provided at the bottom of the support seat 2, the ball head 13 is located in the circular groove 14, an annular groove 15 is provided on the side of the inner wall of the circular groove 14, a groove 26 and a plurality of through grooves 22 are respectively provided on the top of the inner wall of the annular groove 15, the number of through grooves 22 can be two, the groove 26 is located between the two through grooves 22, the inner wall of the groove 26 is rotatably connected to the surface of the ball head 13, the shape of the groove 26 is adapted to the shape of the ball head 13, a slide groove 24 is provided on the opposite sides of the support seat 2, a slider 23 is slidably connected to the inner wall of the slide groove 24, a connecting piece 25 is fixed on the side of the slider 23 away from the ball head 13, and a strap 27 is adhered to the side of the connecting piece 25 away from the slider 23 by Velcro, after the child's hand is punctured and placed on the support seat 2, the strap 27 is attached to the child's hand. The two ends of the strap 27 naturally droop, and then the strap 27 is realized by Velcro 7 is connected to the connecting piece 25, a spring piece 20 is fixed on the side of the slider 23 close to the ball head 13, the spring piece 20 is located inside the through groove 22, an arc strip 16 is fixed on the end of the spring piece 20 away from the slider 23, the arc strip 16 is located inside the annular groove 15, and a plurality of pressing blocks 17 are fixed on the side of the arc strip 16 close to the ball head 13, two groups of mutually symmetrical sensing elements 18 are inlaid on the surface of the ball head 13, the sensing element 18 is a piezoelectric pressure sensor, the sensing element 18 is electrically connected to the battery pack 3 and the buzzer 5, a wire is installed on the side of the support seat 2, and a jack is provided on the side of the bottom plate 1, and the terminal at the end of the wire is inserted into the jack to realize the electrical connection between the battery pack 3 and the sensing element 18, thereby realizing the power supply and signal transmission of the sensing element 18, the sensing element 18 of the battery pack 3 is located below the center of the ball head 13, and the pressing block 17 is located below the sensing element 18 and fits with the surface of the ball head 13.

[0041] During operation, the child's hand is placed on the support seat 2, the child's wrist is restrained by the strap 6, the child's fingers are restrained by the elastic band 9, and the strap 2 7 is fitted to the acupuncture site of the child's hand. When the acupuncture site bulges, the bulge drives the pressure block 17 of the detection mechanism 12 to move upward through the strap 2 7 and presses on the sensing element 18. At this time, the buzzer 5 alarms to prompt the bulge, and multiple pressure blocks 17 of the detection mechanism 12 are pressed on the corresponding sensing element 18 at the same time, and the sensing element 18 sends a signal to the information processing unit. The information processing unit controls the buzzer 5 to alarm through the control unit, thereby realizing automatic monitoring, detection and alarm of the bulge, which is more intelligent.

[0042] like Figure 3 and Figure 6As shown, the surface of the ball head 13 is inlaid with a second sensing element 19, the second sensing element 19 is located below the first sensing element 18, the pressing block 17 is pressed on the second sensing element 19, and the side of the support seat 2 is inlaid with an indicator light 4, the second sensing element 19 is electrically connected to the indicator light 4 and the battery pack 3, the second sensing element 19 is a flexible film pressure sensor, and the wire on the side of the support seat 2 is inserted into the jack on the side of the bottom plate 1 to simultaneously realize the power supply and signal transmission of the second sensing element 19, the combination of the second sensing element 19 and the indicator light 4 provides an intuitive and timely prompt for monitoring the shaking of children's hands. When the child's hand is restrained on the support seat 2, even if there is only a slight shake, the hand movement will drive the pressing block 1 7 rotates and disengages from the sensing element 19. After the pressure on the sensing element 19 disappears, the sensing element 19 sends a signal to the information processing unit. The information processing unit controls the indicator light 4 to light up through the control unit, which conspicuously informs the caregiver or parent that the child's hand is in a shaking state at this moment, prompting them to notice in time and take measures to comfort the child and fix the hand to avoid excessive hand movement, thereby effectively preventing the risk of needle displacement caused by hand movement and then causing bulging. During the shaking of the child's hand, part of the pressure block 17 will rotate to the sensing element 18 and press on the sensing element 18, but multiple sensing elements 18 do not sense pressure at the same time, and no bulging alarm will be issued at this time.

[0043] like Figures 2 to 4 As shown, a plurality of rubber support columns 10 are fixed on the top of the base plate 1, and a plurality of circular holes 11 are opened at the bottom of the support seat 2. The top of the rubber support column 10 is inserted into the circular hole 11 and fits with the top of the inner wall of the circular hole 11. The rubber support column 10 is inserted into the circular hole 11, which can effectively prevent the support seat 2 from rotating in the horizontal direction. At the same time, the rubber support column 10 provides stable support for the support seat 2 to prevent it from shaking at will, maintain the horizontal state of the support seat 2, and ensure that the child's hands are in a comfortable and stable placement environment, which is conducive to the fixation of the needle after intravenous puncture and reduces the risk of needle displacement caused by unstable support. At the same time, when the shaking of the child's hand is transmitted to the support seat 2, the rubber support column 10 is deformed by the shaking force, and the elasticity of the rubber itself is used to provide resistance to the shaking of the support seat 2, effectively preventing the child's hand from shaking aggravated, and further reducing the risk of bulging caused by needle displacement due to hand movement.

[0044] like Figure 2 As shown, the top of the rubber support column 10 is a hemispherical portion 29. The hemispherical portion 29 not only makes it easier for the rubber support column 10 to be inserted into the circular hole 11 at the bottom of the support seat 2, but also during the shaking of the support seat 2, the hemispherical portion 29 can better adapt to the forces in different directions, evenly disperse the pressure, and further improve the support stability.

[0045] like Figure 5As shown, the slider 23 is in an isosceles trapezoidal shape, and the shape of the slide groove 24 is adapted to the shape of the slider 23. The isosceles trapezoidal design of the slider 23 ensures that the slider 23 can only slide stably along a predetermined direction without lateral deviation, thereby ensuring that the thrust generated by the bulge can be accurately transmitted to the position of the pressure block 17.

[0046] like Figure 3 and Figure 8 As shown, the thickness of the spring piece 20 gradually decreases from top to bottom, so that the elastic force in the bottom area of ​​the spring piece 20 is relatively weak. When bulging occurs, the slider 23 can drive the arc strip 16 at the bottom of the spring piece 20 to be lifted upward steadily and smoothly. During this process, the bottom of the spring piece 20 can be deformed smoothly, which greatly reduces the resistance encountered by the arc strip 16 in moving upward, making the upward movement of the pressure block 17 more labor-saving, ensuring that even a slight bulging change can quickly trigger the displacement of the pressure block 17 and be accurately captured by the sensing element 18, effectively improving the detection accuracy of the bulging phenomenon.

[0047] like Figure 8 As shown, the two opposite sides of the spring piece 20 are provided with inclined surfaces 21, and the width of the top of the spring piece 20 is greater than the width of the bottom of the spring piece 20. The design of the inclined surface 21 makes the bottom of the spring piece 20 smoother during the deformation process, and combined with the thickness gradient design, the deformation of the bottom area is easier, further improving the flexibility of the upward movement of the pressure block 17, thereby enhancing the sensitivity of bulge detection.

[0048] like Figure 3 As shown, the center of the arc strip 16 is located on the central axis of the ball head 13. When the bulge occurs and pushes the arc strip 16 upward, it can be evenly stressed along the surface of the ball head 13 and drive multiple pressure blocks 17 to move simultaneously, while ensuring the consistency and accuracy of the movement of each pressure block 17, thereby avoiding the pressure block 17 from accidentally touching the sensing element 18 due to inconsistent movement.

[0049] like Figure 7 As shown, an inclined guide surface 27 is provided at the bottom of the arc strip 16, and the inclined guide surface 27 is used to guide the ball head 13 when it is inserted into the groove 26. When the disinfection of the arc strip 16 is completed and the support seat 2 is reinstalled, the circular groove 14 at the bottom of the support seat 2 is aligned with the ball head 13, and then the support seat 2 is pressed. The top of the ball head 13 will squeeze the guide surface 27 of the arc strip 16, so that the arc strip 16 drives the spring piece 20 to deform, until the ball head 13 is tightly fitted with the inner wall of the groove 26. The arc strip 16 is stuck at the ball head 13 again under the elastic force of the spring piece 20, so as to realize the convenient connection between the support seat 2 and the base plate 1, and the guidance of the ball head 13 when it is inserted into the groove 26 is realized by the guide surface 27, thereby facilitating the connection between the ball head 13 and the support seat 2.

[0050] like Figure 3As shown, the ball head 13, the slider 23 and the arc strip 16 are all hollow, which effectively reduces the weight of the slider 23 and the arc strip 16 without affecting the overall structural strength, and greatly reduces the influence of the slider 23 and the arc strip 16's own weight on the upward movement of the pressure block 17. The hollow setting of the ball head 13 can save the material cost of manufacturing the ball head 13.

[0051] The working principle of the technical solution provided by the present invention is as follows:

[0052] First, fix the base plate 1 to the armrest of the infusion chair through the strap 3 28 to ensure that the entire device is stable and does not shake. Then, gently place the child's hand after intravenous puncture on the support seat 2, and fit the fingers on the curved surface 8 at the end of the support seat 2. Then use the strap 6 attached to the side of the support seat 2 with Velcro to restrain the child's wrist. At the same time, insert the fingers between the elastic band 9 and the curved surface, and use the elastic band 9 to restrain the child's fingers to ensure that the child's hand is relatively still during the infusion.

[0053] After the child's hand is properly fixed, the strap 27 is accurately fitted to the needle puncture site of the hand and connected to the connecting piece 25 on the slider 23 through the Velcro. When the needle puncture site bulges due to needle displacement or other reasons, the thrust generated by the bulge will be quickly transmitted to the connecting piece 25 along the strap 27, thereby driving the slider 23 to move upward along the inner wall of the slide groove 24, so that the slider 23 drives the pressure block 17 on the arc strip 16 to move upward through the spring sheet 20. Due to the influence of the thickness of the spring sheet 20 decreasing from top to bottom and the width decreasing from top to bottom, the elastic force in the bottom area of ​​the spring sheet 20 is relatively weak. When bulging occurs, the slider 23 The arc strip 16 at the bottom of the spring sheet 20 can be driven to be lifted upward steadily and smoothly. In this process, the bottom of the spring sheet 20 can be flexibly deformed due to the shape of the spring sheet 20 itself, which greatly reduces the resistance encountered by the upward movement of the arc strip 16, making the upward movement of the pressing block 17 lighter and more labor-saving. After the pressing block 17 moves upward, multiple pressing blocks 17 are pressed on the corresponding sensing element 18 at the same time. After the sensing element 18 is triggered, the buzzer 5 will immediately issue a loud alarm, and promptly remind the medical staff of the bulge condition, so that the caregiver or parent can promptly inform the medical staff so that the medical staff can rush to deal with it properly.

[0054] When a bulge occurs, pull the strap 27 to separate it from the connecting piece 25 to prevent the strap 27 from causing pressure on the bulge position, and then wait for medical staff to come and deal with it. At the same time, after the strap 27 is separated from the child's hand, under the elastic force of the spring piece 20 and the influence of the shape of the ball head 13 itself, the pressure block 17 on the arc strip 16 gradually moves downward and separates from the sensing element 18. After separation, the alarm can be lifted, or the slider 23 can be directly pressed to make the slider 23 drive the pressure block 17 to move downward through the spring piece 20 and the arc strip 16 and separate from the sensing element 18.

[0055] When the child's hand is restrained on the support seat 2, when the hand shakes slightly, the hand movement will also drive the pressure block 17 to rotate through the support seat 2 and disengage from the sensing element 19. After disengagement, the indicator light 4 lights up, which conspicuously informs the caregiver or parent that the child's hand is in a shaking state at the moment, prompting them to notice in time and take measures to comfort the child and fix the hand to avoid excessive hand movement, thereby effectively preventing bulging. At the same time, after the support seat 2 shakes, the several rubber support columns 10 fixed on the top of the bottom plate 1 play a role. The top of the rubber support column 10 is semi- The ball portion 29 is inserted into the circular hole 11 opened at the bottom of the support seat 2 and fits against the top of the inner wall of the circular hole 11. On the one hand, the rubber support column 10 provides stable support for the support seat 2 to prevent it from shaking randomly and always maintain the horizontal state of the support seat 2; on the other hand, when the shaking of the child's hand is transmitted to the support seat 2, the rubber support column 10 is deformed by the shaking force, and at the same time, the elastic force of the rubber support strip is used to provide resistance to the shaking of the support seat 2, which effectively prevents the child's hand from shaking more severely and further reduces the risk of bulging caused by needle displacement due to random hand movements.

[0056] When the infusion is completed and the device needs to be disinfected, it is only necessary to pull the support seat 2 upwards so that the ball head 13 squeezes the pressing block 17, and the pressing block 17 drives the spring piece 20 to deform through the arc strip 16. When the ball head 13 is separated from the arc strip 16 and pulled out of the circular groove 14, the arc strip 16 can be completely exposed, which is convenient for medical staff to perform disinfection operations. At the same time, the fixing of the strap three 28 to the bottom plate 1 is released, and the bottom plate 1 is removed from the armrest of the infusion chair for simultaneous disinfection. After the disinfection work is completed and the support seat 2 is reinstalled, the bottom plate 1 is first pulled out through the strap three. 28 is fixed on the armrest of the infusion chair, and then the circular groove 14 at the bottom of the support seat 2 is aligned with the ball head 13, and then the support seat 2 is pressed, the top of the ball head 13 will squeeze the guide surface 27 of the arc strip 16, so that the arc strip 16 drives the spring piece 20 to deform, until the ball head 13 is tightly fitted with the inner wall of the groove 26, and the arc strip 16 is stuck at the ball head 13 again under the elastic force of the spring piece 20, so as to realize the convenient connection between the support seat 2 and the bottom plate 1, and the separation and connection of the support seat 2 and the ball head 13 are simpler and more convenient, thereby greatly facilitating daily disinfection and maintenance work.

[0057] When a bulge occurs and venipuncture is repeated on the child's other hand, the bulge and hand shaking can be tested again by repeating the above steps.
