Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an anti-drop-off infusion device for pediatric care. Background Technology

[0002] When children have a cold or other illness, intravenous infusion is often necessary to help them recover quickly. Intravenous infusion is a common method of drug administration, mainly through the vein, which can quickly deliver drugs or fluids to various parts of the body to exert a therapeutic effect. However, children are often quite active during intravenous infusion, and their frequent limb movements can easily cause the infusion needle to dislodge from the blood vessel. This not only interrupts the infusion process but may also damage the child's skin and blood vessels. Therefore, when children receive intravenous infusion, it is usually necessary to use an anti-dislodgement infusion device to fix the infusion site and ensure the safety and continuity of the infusion process.

[0003] A search revealed that Chinese patent CN117942448B discloses an anti-dislodgement infusion device for children's care, including an infusion seat, an infusion stand on one side of the back of the infusion seat, a support rod with a hook at the top of the support rod, and a support frame mounted on both sides of the infusion seat. The support frame includes two side brackets, which are fixed to the infusion seat. A first support plate and a second support plate are respectively fixed to the top of the two side brackets, and a support assembly is rotatably connected between the first and second support plates. This solution primarily uses a binding assembly to wrap around the child's limbs to prevent the needle from dislodging due to arm movement. However, in practical use, it still has the following shortcomings:

[0004] The aforementioned infusion device primarily uses a binding component to immobilize the child's limbs. However, when the binding component immobilizes the child's arm, it inevitably applies a certain restraining force to the arm. The main purpose is to restrict arm movement and prevent the infusion needle from shifting or falling out due to limb movement. However, this restraining force can affect blood circulation in the child's arm, leading to discomfort at the infusion site. This discomfort can prompt the child to scratch the infusion site, which may not only directly cause the needle to fall out but also further exacerbate the child's discomfort, causing the child to struggle. Due to the restraining effect of the binding component, the child's struggling behavior may be restricted. This interaction between restraint and struggle may cause friction between the needle at the infusion site and the binding component. This friction not only increases the risk of needle dislodgement but may also cause additional damage to the tissue at the infusion site.

[0005] To address the aforementioned issues, this application proposes an anti-drop-off infusion device for child care. Summary of the Invention

[0006] This invention proposes an anti-dislodgement infusion device for pediatric care, which solves the problem in related technologies where, when an infusion device is used to fix a child's arm with a binding component, the restraining force affects blood circulation, causing discomfort at the infusion site, leading to scratching and struggling, which in turn causes the needle to rub against the binding component, increasing the risk of needle dislodgement and tissue damage.

[0007] The present invention discloses an anti-drop-off infusion device for pediatric care, comprising:

[0008] An infusion chair with an infusion stand on one side for hanging infusion bottles;

[0009] Armrest blocks, installed in the armrest area of ​​the infusion chair, are used to support the child's hands;

[0010] The finger limiting component is installed at the front end of the handrail block to limit the finger of the child. When the finger limiting component is subjected to external force, it can elastically extend and retract along the length of the handrail block.

[0011] The protective component, installed on the handrail block, is used to cover the child's arm and restrict its range of motion. It works in conjunction with the finger limiting component. When the finger limiting component elastically extends and retracts, the protective component moves synchronously.

[0012] The pressure-blocking component is installed on the outside of the handrail block, through which the infusion tube passes, and works in conjunction with the finger limiting component. When the finger limiting component undergoes significant elastic extension and contraction, it drives the pressure-blocking component to press and limit the infusion tube.

[0013] As a further optimization of the present invention, the finger limiting component includes a finger ring, an elastic loading component, and a rod-type elastic component. A cavity is provided inside the armrest block. The rod-type elastic component is installed in the cavity and one end of it slides through the front end of the armrest block. The elastic loading component is installed at one end of the rod-type elastic component. The finger ring is installed on the elastic loading component and is used to limit the finger of the child.

[0014] As a further optimization of the present invention, the ring component includes an arc-shaped magnetic rod, which is mounted on an elastic loading component. Multiple slidable magnetic balls are magnetically sleeved on the arc-shaped magnetic rod, and a ring body is mounted on each of the multiple magnetic balls. An annular opening is integrally formed in the ring body, and an annular bladder is installed inside the annular opening. An inflation / deflation nozzle communicating with the annular bladder is installed on the ring body.

[0015] As a further optimization of the present invention, the elastic loading member includes a hollow block, which is installed at one end of the rod-type elastic member. A hollow groove is formed inside the hollow block, and a vertical insertion rod is slidably connected to the hollow block. A loading ball is installed at the top of the insertion rod, and an arc-shaped magnetic rod is fixed on the loading ball. A first spring is sleeved on the insertion rod and located inside the hollow groove. The two ends of the first spring are respectively connected to the loading ball and the bottom of the hollow block.

[0016] As a further optimization of the present invention, the rod-type elastic element includes a loading rod, a loading block, and a second spring. The loading rod is disposed in the cavity inside the handrail block and is arranged along the length direction of the handrail block. One end of the loading rod slides through the front end of the handrail block. The hollow block is installed at one end of the loading rod. The loading block is fixed in the middle of the loading rod and located in the cavity. The second spring is sleeved on the loading rod, and both ends of the second spring are respectively connected to the inner wall of one end of the loading block and the handrail block.

[0017] As a further optimization of the present invention, the protective component includes an arc-shaped elastic cover, a water bladder, and a protective part. The top of the handrail block has a sliding opening communicating with the cavity. The arc-shaped elastic cover is disposed on the top of the handrail block. The bottom of the arc-shaped elastic cover is equipped with a docking rod connected to the loading block, and the docking rod slides in cooperation with the sliding opening. The water bladder is detachably connected inside the arc-shaped elastic cover. The upward part of the arc-shaped elastic cover has a notch, and the protective part is disposed at the notch for opening and closing the notch.

[0018] As a further optimization of the present invention, the protective part includes a protective film, a first magnetic block, a second magnetic block and two third magnetic blocks. The protective film and the two third magnetic blocks are all connected to the notch at one end of the arc-shaped elastic cover, and the protective film is located between the two third magnetic blocks. The end of the protective film is connected to the first magnetic block, and the other end of the arc-shaped elastic cover is connected to the second magnetic block located at the notch. The first magnetic block can be used to magnetically connect with the second magnetic block and the third magnetic block respectively.

[0019] As a further optimization of the present invention, the water bladder includes an arc-shaped bladder, the inner wall of the arc-shaped elastic cover is provided with a rough surface, the arc-shaped bladder is disposed inside the arc-shaped elastic cover, and the outer periphery of the arc-shaped bladder is bonded to the rough surface by Velcro, the end of the arc-shaped bladder is connected to a water injection shaft, and a sealing plug is inserted into the water injection shaft.

[0020] As a further optimization of the present invention, the pressure-blocking component includes a loading frame and an elastic pressure-blocking part. The loading frame is installed on the outside of the handrail block, and an opening for the infusion tube to enter and exit is formed on the side of the loading frame. The elastic pressure-blocking part is installed inside the loading frame to press against the infusion tube, and the elastic pressure-blocking part cooperates with the loading block. A magnetic sheet is installed at the bottom inside the loading frame, and the magnetic sheet is used to magnetically connect with the elastic pressure-blocking part when it moves down.

[0021] As a further optimization of the present invention, the elastic pressing part includes a connecting rod that slides through the top of the loading frame and extends into it. A pressing block located inside the loading frame is installed at the bottom end of the connecting rod. A third spring is sleeved on the connecting rod, and the two ends of the third spring are respectively connected to the pressing block and the top of the loading frame. A rubber sleeve is fitted around the outer periphery of the pressing block. A magnetic block that passes through the rubber sleeve and corresponds to the magnetic sheet is installed at the bottom of the pressing block. Openings are provided at the bottom of the loading frame and on the outer side of the handrail block. A pull rope is connected to the bottom of the pressing block, and the pull rope passes through the opening and is connected to the loading block.

[0022] The above-described technical solution of the present invention has the following beneficial technical effects:

[0023] 1. The finger limiting component and the protective component work together to restrict the child's hand movements through the finger ring, while the elastic loading component and the rod-type elastic component allow the hand to move within a certain range to prevent excessive struggle from causing the needle to fall out. At the same time, the rod-type elastic component can drive the protective component to move synchronously, continuously protecting the infusion site on the arm and preventing the child from grabbing the needle. This effectively limits the child's excessive hand movements, reduces the risk of needle dislodgement, and ensures the safety and stability of the infusion process.

[0024] 2. When a child sneezes during an IV infusion, the body will cause the arm to shake. Since the child's fingers are fixed by the finger ring, the elastic loading component can limit the vertical elastic movement of the fingers fixed on the finger ring. Furthermore, since the infusion position of the arm is placed inside the protective component, it can provide cushioning protection when the arm shakes. This design, through the cooperation of the finger ring, elastic loading component, and protective component, effectively cushions the arm shaking caused by sneezing, reduces the force on the infusion site, further reduces the risk of needle dislodgement or displacement, and improves the comfort and safety of the infusion process.

[0025] 3. In winter, when the ambient temperature is low, the skin temperature at the infusion site of children drops and blood circulation slows down, which can easily cause discomfort. The water bladder on the protective component can be removed from the arc-shaped elastic cover, filled with warm water, and then the infusion tube can be placed tightly against the inner wall of the arc-shaped elastic cover. The water bladder can then be reinstalled to cover part of the infusion tube, thus heating the medication. The child's arm is placed in the middle of the water bladder to keep the infusion site warm. In summer, cold water can be filled to keep it cool. This design, through the detachable water bladder, allows for adjustment of the infusion site temperature according to the season, keeping it warm in winter and cooling it in summer, effectively alleviating blood circulation problems caused by temperature discomfort and improving the child's comfort and infusion experience.

[0026] 4. When a child struggles, they may grab the IV tubing, causing the needle to fall out. To address this, a pressure-blocking component is installed on the outside of the handrail block, which works in conjunction with the finger-limiting component. During infusion, the IV tubing is inserted into the loading frame and placed below the elastic pressure-blocking part. When the child struggles, the rod-shaped elastic element on the finger-limiting component extends and retracts significantly, causing the elastic pressure-blocking part to move down and magnetically connect with the magnetic plate, thereby pressing and locking the IV tubing to prevent it from being grabbed and causing the needle to fall out. At the same time, the pressure reduces the flow of medication, preventing needle displacement that could lead to drug extravasation, local swelling, and pain. This design, through the linkage mechanism between the pressure-blocking component and the finger-limiting component, automatically locks the IV tubing when the child struggles, improving the safety and reliability of the infusion process.

[0027] 5. This invention uses a pressure-retaining component to limit the infusion tube and a water-filled bladder inside an arc-shaped elastic cover to fix part of the infusion tube, thus playing a coordinating and fixing role. This effectively restricts the movement space of the infusion tube, preventing the child from accidentally touching the infusion tube while struggling or grabbing, thereby avoiding needle dislodgement or displacement. This further improves the safety and stability of the infusion process, reduces medical risks, and enhances the child's comfort and nursing efficiency. Attached Figure Description

[0041] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0042] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0043] Example 1

[0044] like Figure 1-11 As shown, the present invention proposes an anti-drop-off infusion device for pediatric care, comprising:

[0045] The infusion seat 1 has an infusion stand 101 for suspending infusion bottles on one side. A retaining ring 102 is connected to one side of the back of the infusion seat 1. The infusion stand 101 is engaged with the retaining ring 102. The retaining ring 102 has a certain elasticity to clamp the infusion stand 101.

[0046] Armrest block 2 is installed in the armrest area of ​​the infusion seat 1 to support the child's hands;

[0047] The finger limiting component 3 is installed at the front end of the handrail block 2 to limit the finger of the child. When the finger limiting component 3 is subjected to external force, it can elastically extend and retract along the length of the handrail block 2.

[0048] The protective component 4 is installed on the handrail block 2 to cover the child's arm and restrict its range of motion. It works in conjunction with the finger limiting component 3. When the finger limiting component 3 elastically extends and retracts, the protective component 4 moves synchronously.

[0049] The pressure-blocking component 5 is installed on the outside of the handrail block 2, through which the infusion tube passes, and works in conjunction with the finger limiting component 3. When the finger limiting component 3 undergoes significant elastic extension and contraction, it drives the pressure-blocking component 5 to press and limit the infusion tube.

[0050] During intravenous infusion, the child sits in the infusion chair 1, the infusion bottle is suspended on the infusion stand 101, and the arm is placed on the armrest block 2. The finger limiting component 3 restricts the child's fingers, limiting excessive hand movement. When the child's fingers are subjected to force due to discomfort or other reasons, the finger limiting component 3 elastically extends and retracts along the length of the armrest block 2, preventing the hand from being rigidly restrained and causing stronger struggles. The protective component 4 covers the child's arm and moves synchronously with the finger limiting component 3, always restricting the arm to a certain range of motion, preventing the needle from falling out due to large arm movements, and also preventing the child from scratching the infusion site. If the child struggles a lot, the finger limiting component 3 will extend and retract significantly, which will drive the pressure component 5 to press against the infusion tube, preventing the infusion tube from being pulled and causing the needle to shift or fall out. The above design, through elastic limiting and linkage protection, not only provides the child's hand with a certain amount of space to reduce discomfort, but also effectively prevents the needle from falling out due to struggles, scratching, etc., improving the safety of infusion and reducing the care pressure on nursing staff.

[0051] like Figure 2 and Figure 3As shown, in this embodiment, the finger limiting component 3 includes a finger ring 31, an elastic loading component 32, and a rod-type elastic component 33. A cavity is provided inside the armrest block 2. The rod-type elastic component 33 is installed in the cavity, and one end of it slides through the front end of the armrest block 2. The elastic loading component 32 is installed on one end of the rod-type elastic component 33. The finger ring 31 is installed on the elastic loading component 32 and is used to limit the child's fingers. The finger ring 31 is fitted on the child's fingers to limit them. When the fingers are subjected to force, the force is transmitted to the rod-type elastic component 33 through the elastic loading component 32. The rod-type elastic component 33 can slide and extend within the cavity of the armrest block 2, converting the external force on the fingers into elastic deformation, allowing the fingers to move slightly. Since the protective component 4 and the pressure component 5 are both linked to the rod-type elastic component 33, the extension and retraction of the rod-type elastic component 33 will drive the protective component 4 to move synchronously and the pressure component 5 to move accordingly. This design further buffers the force on the hand through multi-level elastic transmission, reducing the discomfort caused by rigid restraint.

[0052] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, the ring component 31 includes an arc-shaped magnetic rod 311, which is mounted on the elastic loading member 32. Multiple slidable magnetic balls 312 are magnetically sleeved on the arc-shaped magnetic rod 311. A ring body 313 is mounted on each of the multiple magnetic balls 312. An annular opening is integrally formed within the ring body 313, and an annular bladder 314 is installed within the annular opening. An inflation / deflation nozzle 315 communicating with the annular bladder 314 is mounted on the ring body 313. The magnetic balls 312 are magnetically sleeved on the arc-shaped magnetic rod 311. The magnetic rod 311 can be adjusted in position according to the distance between the child's fingers, adapting to the finger distribution of different children. The ring body 313 is worn on the finger, and air is inflated or deflated through the inflation / deflation valve 315 into the annular bladder 314. (The structure of the inflation / deflation valve 315 can be referenced from the valve structure on a bicycle; this is existing technology and will not be elaborated further. Specifically, air is inflated into the inflation / deflation valve 315 using an air pump or other inflation device. To deflate, simply press the core post in the middle of the inflation / deflation valve 315.) Figure 6 As can be seen from the image, the tightness of the ring opening can be adjusted to fit fingers of different thicknesses, enhancing the fit between the finger and the ring body 313. The sliding of the magnetic ball 312 and the tightness adjustment of the ring pouch 314 enable the ring part 31 to flexibly fit children of different ages and finger sizes, improving the comfort and stability of wearing, and avoiding finger injury or limit failure caused by unsuitable size.

[0053] like Figure 5As shown, in this embodiment, the elastic loading member 32 includes a hollow block 321, which is installed at one end of the rod-type elastic member 33. A hollow groove is provided inside the hollow block 321, and a vertical insertion rod 322 is slidably connected to the hollow block 321. A loading ball 323 is installed at the top of the insertion rod 322, and an arc-shaped magnetic rod 311 is fixed on the loading ball 323. A first spring 324 located in the hollow groove is sleeved on the insertion rod 322, and the two ends of the first spring 324 are respectively connected to the loading ball 323 and the bottom of the hollow block 321. When the curved magnetic rod 311 is subjected to a vertical force through the loading ball 323, such as when the child raises or lowers their hand, the insertion rod 322 moves up and down accordingly, compressing or stretching the first spring 324. The elastic force of the first spring 324 will buffer the vertical force, allowing the hand to have a certain range of motion in the vertical direction, increasing the elastic mobility of the hand in the vertical direction, further reducing rigid constraints, alleviating the child's discomfort, and at the same time, the buffering effect of the first spring 324 will prevent the needle from vibrating or shifting due to sudden force on the hand, thus improving the stability of the infusion.

[0054] like Figure 3 and Figure 4 As shown, in this embodiment, the rod-type elastic element 33 includes a loading rod 331, a loading block 332, and a second spring 333. The loading rod 331 is disposed in the cavity inside the handrail block 2 and is arranged along the length direction of the handrail block 2. One end of the loading rod 331 slides through the front end of the handrail block 2. A hollow block 321 is installed at one end of the loading rod 331. The loading block 332 is fixed in the middle of the loading rod 331 and located in the cavity. The second spring 333 is sleeved on the loading rod 331, and both ends of the second spring 333 are respectively connected to the loading block 332, the loading block 332, and the loading block 332. One end of the handrail block 2 is connected to the inner wall; when the child struggles, the force is transmitted to the loading rod 331 through the hollow block 321, causing the loading rod 331 to move the loading block 332, thereby compressing or stretching the second spring 333. The elastic force of the second spring 333 causes the loading rod 331 to generate an elastic restoring force, realizing the elastic extension and contraction of the rod elastic element 33, ensuring that the hand's horizontal movement is both flexible and controlled. When the loading block 332 moves with the loading rod 331, it will drive the protective component 4 and the pressure component 5 to move synchronously.

[0055] like Figure 2 and Figure 7As shown, in this embodiment, the protective component 4 includes an arc-shaped elastic cover 41, a water bladder 42, and a protective part 43. The top of the handrail block 2 has a sliding opening 21 communicating with the cavity. The arc-shaped elastic cover 41 is disposed on the top of the handrail block 2. A connecting rod 411 connected to the loading block 332 is installed at the bottom of the arc-shaped elastic cover 41, and the connecting rod 411 slides in cooperation with the sliding opening 21. The water bladder 42 is detachably connected inside the arc-shaped elastic cover 41. A notch is formed in the upward part of the arc-shaped elastic cover 41, and the protective part 43 is disposed at the notch for opening and closing the notch. When the loading block 332 moves with the rod-shaped elastic part 33... When moving, the docking rod 411 slides along the sliding opening 21, causing the arc-shaped elastic cover 41 to move synchronously, always covering the child's arm to restrict the range of motion. The water bag 42 is detachably connected inside the arc-shaped elastic cover 41, and the temperature can be adjusted as needed to form a flexible fit to the infusion site. The notch at the top of the arc-shaped elastic cover 41 can be opened or closed through the protective part 43. When opened, it is convenient to place the arm, and when closed, it can prevent the child from scratching the infusion site, thus achieving continuous protection without restricting the arm. Combined with the elastic extension and retraction of the finger limiting component 3, it not only reduces the child's discomfort, but also effectively reduces the risk of needle dislodgement.

[0056] like Figure 9 As shown, in this embodiment, the protective part 43 includes a protective film 431, a first magnetic block 432, a second magnetic block 433, and two third magnetic blocks 434. The protective film 431 and the two third magnetic blocks 434 are all connected to the notch at one end of the arc-shaped elastic cover 41, and the protective film 431 is located between the two third magnetic blocks 434. The first magnetic block 432 is connected to one end of the protective film 431, and the second magnetic block 433 located at the notch is connected to the other end of the arc-shaped elastic cover 41. The first magnetic block 432 can be used to magnetically connect with the second magnetic block 433 and the third magnetic block 434 respectively. When the first magnetic block 432 and the third magnetic block 434 are magnetically connected, it is used to close the protective film. The protective film 431 is opened when the first magnetic block 432 and the second magnetic block 433 are magnetically connected, which is used to unfold the protective film 431 to close the gap. When the arm needs to be placed, the first magnetic block 432 and the third magnetic block 434 are magnetically connected, the protective film 431 is closed, and the gap of the arc-shaped elastic cover 41 is opened to facilitate the insertion of the arm. After the arm is placed, the first magnetic block 432 and the second magnetic block 433 are magnetically connected, the protective film 431 is unfolded, and the gap is closed. The protective film 431 prevents the child's fingers from reaching into the cover and scratching. The quick opening and closing of the protective film 431 makes the operation convenient and suitable for the rapid nursing needs of children during infusion. The protective film 431 can effectively prevent scratching.

[0057] like Figure 8As shown, in this embodiment, the water bladder component 42 includes an arc-shaped bladder 421. The inner wall of the arc-shaped elastic cover 41 is provided with a textured surface. The arc-shaped bladder 421 is disposed inside the arc-shaped elastic cover 41, and the outer periphery of the arc-shaped bladder 421 is bonded to the textured surface via Velcro 422. A water injection shaft 423 is connected to the end of the arc-shaped bladder 421, and a sealing plug 424 is inserted into the water injection shaft 423. The arc-shaped bladder 421 is quickly bonded to the textured surface of the inner wall of the arc-shaped elastic cover 41 via the outer periphery Velcro 422, enabling convenient assembly and disassembly. This facilitates adding water, changing water, or removal when not needed. Liquids of different temperatures are injected through the water injection shaft 423 (during the water injection operation). During operation, the arc-shaped pouch 421 is removed, the sealing plug 424 on the water injection shaft 423 is opened, and then the water injection tube is inserted into the water injection shaft 423 to inject the liquid into the arc-shaped pouch 421. Then the sealing plug 424 is inserted to seal it. When the arc-shaped pouch 421 fits the arm, it regulates the local temperature through heat transfer, improving comfort. It moves synchronously with the protective component 4 and the finger limiting component 3, continuously controlling the temperature and cushioning to protect the arm. It also limits the range of motion to prevent the needle from falling out. In winter, it covers the infusion tube that is tightly attached to the inner wall of the arc-shaped elastic cover 41, which not only keeps the medicine warm but also helps to fix the infusion tube with pressure, reducing shaking and preventing the needle from shifting.

[0058] Example 2

[0059] When a child struggles, they may grab the IV tubing, causing the needle to dislodge from the infusion site. Furthermore, the needle may shift at the insertion point during struggle, leading to medication seeping into surrounding tissues during continuous infusion, causing local swelling and pain. Therefore, based on Example 1, a structure is designed to limit the movement of the IV tubing, as follows:

[0060] like Figure 3 and Figure 10As shown, in this embodiment, the pressure-retaining component 5 includes a loading frame 51 and an elastic pressure-retaining part 52. The loading frame 51 is installed on the outside of the handrail block 2. An opening for the infusion tube to enter and exit is formed on the side of the loading frame 51. The elastic pressure-retaining part 52 is installed inside the loading frame 51 to press against the infusion tube. The elastic pressure-retaining part 52 cooperates with the loading block 332. A magnetic sheet 511 is installed at the bottom inside the loading frame 51, and the magnetic sheet 511 is used to magnetically connect with the elastic pressure-retaining part 52 when it moves down. The infusion tube is inserted into the frame through the opening on the side of the loading frame 51. Under normal conditions, the elastic pressure-retaining part 52 does not compress the infusion tube, allowing the infusion tube to deliver the medication normally. When the child struggles violently, the loading block 332 of the finger limiting component 3 moves significantly. When the elastic pressing part 52 moves downward with the cooperation of the loading block 332, the magnetic sheet 511 at the bottom of the loading frame 51 is magnetically connected to the elastic pressing part 52, so that the elastic pressing part 52 presses against the infusion tube, forming a limiting and fixing of the infusion tube, preventing the infusion tube from being pulled or shaken, which could cause the needle to shift or fall off. This design achieves dynamic limiting of the infusion tube, which only works when the child struggles greatly. It avoids unnecessary pressure on the infusion tube under normal conditions, and can effectively protect the safety of infusion in dangerous situations, reducing the risk of needle dislodgement. In addition, after pressing the infusion tube, it can reduce the flow of the medicine in the infusion tube, preventing the needle from shifting when the child struggles, which may cause the medicine to seep into the surrounding tissues, causing local swelling and pain.

[0061] like Figure 11 As shown, in this embodiment, the elastic pressing part 52 includes a connecting rod 521. The connecting rod 521 slides through the top of the loading frame 51 and extends into its interior. A pressing block 522 located inside the loading frame 51 is installed at the bottom end of the connecting rod 521. A third spring 523 is sleeved on the connecting rod 521, and the two ends of the third spring 523 are respectively connected to the pressing block 522 and the top of the loading frame 51. A rubber sleeve 524 is sleeved on the outer periphery of the pressing block 522. A magnetic block 526 corresponding to the magnetic sheet 511 is installed at the bottom of the pressing block 522, passing through the rubber sleeve 524. Openings are provided at the bottom of the loading frame 51 and the outer side of the handrail block 2. A pull rope 525 is connected to the bottom of the pressing block 522, and the pull rope 525 passes through the opening and is connected to the loading block 332.

[0062] The infusion tube is inserted through the opening of the loading frame 51 and positioned below the pressure block 522. Under normal conditions, the third spring 523 supports the pressure block 522, keeping it at a certain distance from the infusion tube to avoid affecting the flow of the medication. When the child struggles violently, the loading block 332 on the rod-type elastic element 33 reciprocates, pulling the pressure block 522 downward via the pull rope 525. The third spring 523 is stretched, and the magnetic block 526 and the magnetic sheet 511 are magnetically attracted. The rubber sleeve 524 presses tightly against the infusion tube, restricting its movement and reducing the flow of medication within the infusion tube. After the struggle stops, the tube can be manually reset. To reset, simply push the pressure block 522 upward or pull the connecting rod 521 upward. Under the elastic action of the third spring 523, the pressure block 522 moves away from the infusion tube and returns to its original position.

[0063] The specific working principle of this invention is as follows:

[0064] The child sits on the infusion chair 1, with the infusion bottle suspended on the infusion stand 101 on one side and the arm resting on the armrest block 2. Then, the child's arm is punctured through the needle on the infusion tube. At this time, the notch of the protective part 43 in the protective component 4 is opened, and the first magnetic block 432 and the third magnetic block 434 are magnetically attracted to each other. The arm is placed into the arc-shaped elastic cover 41. Then, the first magnetic block 432 and the second magnetic block 433 are magnetically attracted to each other, so that the protective film 431 seals the notch on the arc-shaped elastic cover 41 to prevent the child from scratching the infusion site on the arm.

[0065] According to the size of the child's finger, slide the magnetic ball 312 on the arc-shaped magnetic rod 311 in the finger ring 31, adjust the position of the finger ring body 313, put the finger into the finger ring body 313, inflate the ring bladder 314 through the inflation / deflation nozzle 315, so that the ring bladder 314 fits the finger, and the infusion tube passes through the loading frame 51 of the pressure assembly 5 to complete the initial setting.

[0066] When the child struggles, the force applied to the fingers causes the insertion rod 322 of the elastic loading component 32 to compress or stretch the first spring 324, achieving elastic buffering in the vertical direction. At the same time, the force is transmitted to the rod-type elastic component 33, causing the loading rod 331 to drive the loading block 332 to compress or stretch the second spring 333, elastically extending and retracting along the length of the handrail block 2, allowing the hand to move within a certain range, avoiding rigid restraint that could cause stronger struggles.

[0067] The arc-shaped elastic cover 41 of the protective component 4 is connected to the loading block 332 of the rod-type elastic component 33 via the docking rod 411. When the finger limiting component 3 elastically extends and retracts, the docking rod 411 slides along the sliding opening 21, causing the arc-shaped elastic cover 41 to move synchronously, always covering the arm infusion site, limiting the range of arm movement, and preventing the child from scratching the needle. The water bladder 42 inside the arc-shaped elastic cover 41 can be removed via Velcro 422, filled with warm or cold water, and then reinstalled. It regulates the temperature around the arm through heat transfer, improving comfort in different environments.

[0068] Under normal circumstances, the elastic pressure part 52 of the pressure component 5 does not apply pressure to the infusion tube, ensuring normal delivery of the medication. When the child struggles violently, causing the finger limiting component 3 to extend and retract significantly, the loading block 332 pulls the pressure block 522 of the elastic pressure part 52 downward through the pull rope 525, the third spring 523 stretches, the magnetic block 526 and the magnetic sheet 511 are magnetically attracted, and the rubber sleeve 524 presses tightly against the infusion tube, restricting its movement and reducing the flow of the medication, preventing the needle from falling off due to pulling. After the struggle stops, it can be manually reset.

[0069] Through the above-mentioned flexible limiting, linkage protection and emergency pressure resistance mechanism of multiple components, the device can not only give the child a certain amount of room to move to reduce discomfort, but also effectively prevent the needle from falling out, ensuring the safety and stability of the infusion process.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
