Description

Technical Field

[0001] This invention relates to the field of infusion equipment technology, and in particular to a hanging and fixing device for children's IV drip bottles. Background Technology

[0002] In pediatric clinical intravenous infusion nursing, intravenous therapy is a common method for diagnosing and treating childhood diseases. The proper hanging and securing of the infusion bottle and the prevention of dislodgement of the infusion needle are crucial for ensuring a smooth infusion process. Currently, the traditional method used in clinical practice is to directly hang the infusion bottle on the hook of the infusion stand, with the infusion needle inserted directly into the bottle. This method generally meets the needs of adult infusion settings.

[0003] However, for infusion devices specifically designed for pediatric infusion care, such as the invention patent with application number CN202511275402.7, a non-dislodgeable pediatric infusion device is disclosed. This device includes: an infusion seat with an infusion stand for suspending the infusion bottle on one side; an armrest block installed in the armrest area of ​​the infusion seat to support the child's hand; a finger limiting component installed at the front end of the armrest block to limit the child's fingers; the finger limiting component can elastically extend and retract along the length of the armrest block when subjected to external force; and a protective component installed on the armrest block to cover the child's arm and restrict its range of motion. This invention, through the synergistic action of the finger ring, elastic loading component, rod-type elastic component, and protective component, restricts excessive hand movement, cushions arm swaying, reduces the risk of needle dislodgement, allows for temperature adjustment in winter and summer to improve comfort, and links the pressure component and finger limiting component to automatically lock the infusion tubing, preventing accidental contact and enhancing infusion safety and stability.

[0004] Based on the above-mentioned patents and existing infusion devices for pediatric intravenous care, the following shortcomings still exist in practical applications: Children's active nature can easily cause the puncture device to shift or fall off: Children, especially young children, have a low degree of cooperation during infusion procedures. During the infusion process, they are prone to crying, restlessness, and random limb movements that pull on the infusion tube. The pulling force may cause the puncture device to separate from the infusion bottle or shift, which may lead to problems such as interruption of drug delivery, blood backflow at the puncture site, and leakage. This not only affects the treatment effect, but may also cause the puncture tube to become blocked due to blood clotting, requiring re-puncture, increasing the child's physical pain and psychological resistance. The lack of immediate warning for puncture device displacement and the delayed nursing response: In the traditional infusion mode, medical staff and parents can only judge whether the puncture device has been displaced by manual observation. However, the number of patients in the pediatric infusion room is large, the medical staff have limited energy, and parents cannot keep a close eye on it at all times. Often, the displacement of the puncture device and blood return / leakage can only be discovered after they have already occurred. The nursing response is obviously delayed, which can delay the treatment time and aggravate the adverse reactions of children to infusion. Summary of the Invention

[0005] This invention relates to a hanging and fixing device for children's IV drip bottles, which solves the problem that children's active pulling on the IV tubing during infusion can easily cause the puncture device to shift and fall off, while traditional infusion methods lack immediate warning means and rely solely on manual observation, which can easily lead to delayed nursing response.

[0006] This invention provides a hanging water bottle fixing device for children, specifically including: a hanging base, on which three clamping blocks are fixedly installed in a circular array on the top surface of the hanging base, and a plug-in hole is provided at the central part of the hanging base; a hanging auxiliary block is provided below the hanging base; a circular storage groove is provided on the bottom surface of the hanging base, and the top surface of the inner end of the circular storage groove is fixedly connected to the top surface of the hanging auxiliary block by a spring connector; a plug-in groove is provided between the top and bottom surfaces of the hanging base; a lower insulating sheet is fixedly installed on the top surface of the hanging auxiliary block, a conductive sheet is fixedly installed on the top surface of the lower insulating sheet, and an upper insulating sheet is fixedly installed on the top surface of the conductive sheet; the lower insulating sheet, the conductive sheet, and the upper insulating sheet are all slidably plugged into the plug-in groove; a conductive block is embedded in the left and right sides of the inner end of the plug-in groove; when the spring connector is in its natural state, the upper insulating sheet is in contact with the two conductive blocks, and at this time the conductive sheet is not in contact with the conductive blocks.

[0007] Furthermore, the clamping block has an annular segment structure and is coaxially arranged with the suspension base; a rubber clamping pad is fixedly bonded to the inner circumference of each of the three clamping blocks; and a lifting ring is fixedly installed on the top surface of each of the three clamping blocks.

[0008] Furthermore, the suspension auxiliary block has an insertion hole at its central axis, and a rubber locking block is fixedly installed inside the insertion hole. The rubber locking block has a locking insertion hole at its central axis.

[0009] Furthermore, when the top surface of the suspension auxiliary block is in contact with the bottom surface of the suspension base, the spring connector is in a compressed state, while the lower insulating sheet is in contact with the two conductive blocks, and at this time the conductive sheet is not in contact with the conductive blocks.

[0010] Furthermore, a microcontroller is installed inside the suspension base; a cut surface is opened on the front end face of the suspension base, and a buzzer and an on / off switch are installed on the cut surface, and both the buzzer and the on / off switch are electrically connected to the microcontroller.

[0011] Furthermore, the suspension base is also equipped with a power supply unit; a power display and a charging port electrically connected to the power supply unit are also installed on the cut surface.

[0012] Furthermore, the two conductive blocks are connected to the control circuit of the buzzer; when the conductive sheet contacts the two conductive blocks, the control circuit is connected and the buzzer is in the start state; otherwise, the control circuit is in the cut-off state and the buzzer is in the off state.

[0013] Furthermore, a limiting pin is fixedly installed on both the left and right sides of the top surface of the suspension auxiliary block; a limiting insertion hole penetrating the bottom surface is opened on both the left and right sides of the top surface of the suspension base; the two limiting pins are slidably inserted into the two limiting insertion holes respectively.

[0014] This invention provides a hanging and fixing device for children's water bottles, which has the following beneficial effects: This invention utilizes the elastic reset properties of the spring connector, combined with the coordinated operation of the conductive sheet, conductive block, and insulating sheet, to construct an automatic warning circuit for puncture device displacement. When a child pulls on the infusion tube, causing the puncture device to separate from the infusion bottle and the suspension auxiliary block to move downward, the conductive sheet will contact the conductive block, connecting the buzzer control circuit. The microcontroller will trigger the buzzer to emit a continuous warning sound. Addressing the characteristics of children's active nature and weak self-control, this invention eliminates the need for constant monitoring of the puncture site, reducing the nursing and monitoring burden on medical staff and parents. It can immediately alert medical staff or parents to handle the situation promptly, effectively avoiding infusion risks such as interrupted drug delivery, backflow of blood, and leakage at the puncture site, significantly reducing safety risks during children's infusions and improving the safety of infusion care.

[0015] The rubber locking block inside the suspension auxiliary block of this invention can elastically contract and wrap around the puncture device rod, achieving temporary fixation of the puncture device and the device. This not only prevents the puncture device from loosening directly when a child slightly pulls on the infusion tube, but also serves as a guide during puncture device installation, ensuring the docking accuracy between the puncture device and the infusion bottle. In conjunction with the sliding insertion structure of the limiting pin and the limiting hole, the movement and rotation direction of the suspension auxiliary block are restricted, ensuring the accurate alignment of the subsequent warning linkage structure and improving the overall mechanical linkage reliability of the device.

[0016] This invention uses three clamping blocks arranged in a ring array, along with an inner rubber clamping pad, to form a flexible clamp that fits the outer wall of children's infusion bottles of different sizes. This ensures the stability of the infusion bottle when suspended, preventing the bottle from shaking or tipping over, while also avoiding damage to the bottle caused by hard clamps. At the same time, the coaxial design of the clamping blocks and the suspension base ensures that the force on the suspended infusion bottle is even, meeting the routine needs of clinical infusion use, and making installation and disassembly convenient.

[0017] The invention features a built-in power supply unit in the suspension base to power the warning system. The front-end power display shows the remaining power in real time, and the charging port supports repeated charging of the power supply unit, eliminating the need for frequent battery replacements. This design is energy-saving, environmentally friendly, and has low operating costs. The on / off switch allows manual control of the warning system's activation and deactivation, making it suitable for scenarios where warnings are not required, such as pre-infusion preparation and puncture device repositioning. This flexible operation meets the actual nursing needs of medical staff. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described 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.

[0022] Example: Please refer to Figures 1 to 11 : This invention proposes a hanging and fixing device for children's infusion bottles, comprising: a hanging base 1, with three clamping blocks 101 fixedly installed in a circular array on the top surface of the hanging base 1. The three-way encircling structure can conform to the outer wall of the infusion bottle to form a stable clamping, and the circular array distribution ensures that the infusion bottle is evenly stressed, avoiding tilting of the bottle due to force on one side. A insertion hole 1012 is provided at the axial center of the hanging base 1; a hanging auxiliary block 2 is provided below the hanging base 1; and a circular retaining hole is provided on the bottom surface of the hanging base 1. The annular storage slot 1011 is fixedly connected to the top surface of the suspension auxiliary block 2 via a spring connector 202. A common insertion slot 109 is provided between the top and bottom surfaces of the suspension base 1. A lower insulating sheet 203 is fixedly installed on the top surface of the suspension auxiliary block 2, a conductive sheet 207 is fixedly installed on the top surface of the lower insulating sheet 203, and an upper insulating sheet 208 is fixedly installed on the top surface of the conductive sheet 207. The lower insulating sheet 203, the conductive sheet 207, and the upper insulating sheet 208... All pieces 208 slide into the insertion slots 109; a conductive block 1013 is embedded in the left and right sides of the inner end of the insertion slots 109; when the spring connector 202 is in its natural state, the upper insulating piece 208 is in contact with the two conductive blocks 1013, and at this time the conductive piece 207 is not in contact with the conductive blocks 1013; the clamping block 101 has an annular segment structure, and the clamping block 101 is coaxially arranged with the suspension base 1; a rubber clamping pad is fixedly bonded to the inner circumferential surface of each of the three clamping blocks 101. 102 has elastic and flexible properties, which on the one hand increases the friction with the outer wall of the infusion bottle, improves the stability of the infusion bottle clamping, and prevents the bottle from shaking or tipping; on the other hand, it avoids damage to the bottle body caused by direct contact between the hard clamp and the bottle, protecting the infusion bottle and the internal medicine; each of the three clamping blocks 101 has a hanging ring 103 fixedly installed on its top surface, and the device can be suspended on the support structure such as the infusion stand through the hanging ring 103 on the suspension base 1 to achieve overall fixed installation and meet the routine use needs of clinical infusion.

[0023] The suspension auxiliary block 2 has a mounting hole 206 at its axial center. A rubber locking block 204 is fixedly installed inside the mounting hole 206. The rubber locking block 204 has a locking insertion hole 205 at its axial center, through which the puncture device rod passes. The elastic contraction properties of the rubber form a wrapping and limiting effect on the puncture device rod, temporarily fixing the puncture device to the suspension auxiliary block 2. This prevents the puncture device from loosening directly when a child slightly pulls on the infusion tube. The movable displacement can also serve as a guide during the installation of the puncture device, further ensuring the docking accuracy between the puncture device and the infusion bottle; at the same time, when the puncture device is subjected to a large pulling force and shifts, it can move synchronously with the puncture device and trigger the subsequent warning structure; when the top surface of the suspension auxiliary block 2 is in contact with the bottom surface of the suspension base 1, the spring connector 202 is in a compressed state, while the lower insulating sheet 203 is in contact with the two conductive blocks 1013, and at this time the conductive sheet 207 is not in contact with the conductive block 1013.

[0024] The suspension base 1 contains a microcontroller 1015. A cut surface 104 is provided on the front end of the suspension base 1, on which a buzzer 105 and an on / off switch 107 are installed, both electrically connected to the microcontroller 1015. The suspension base 1 also contains a power supply unit 1014, which provides power. A power display 106 and a charging port 108, electrically connected to the power supply unit 1014, are also installed on the cut surface 104. The power display 106 can display the remaining power of the power supply unit 1014 in real time, and the power supply unit 1014 can be charged through the charging port 108 when the power is insufficient. Two conductive blocks 1013 are connected to the control circuit of the buzzer 105. When the conductive sheet 207 contacts the two conductive blocks 1013, the control circuit is connected, and the buzzer 105 is in the activated state; conversely, when the conductive sheet 207 is in contact with the two conductive blocks 1013, the control circuit is connected, and the buzzer 105 is in the activated state.

[0025] The suspension auxiliary block 2 has a limiting pin 201 fixedly installed on both the left and right sides of its top surface; the suspension base 1 has a limiting hole 1010 penetrating its bottom surface on both the left and right sides of its top surface; the two limiting pins 201 are slidably inserted into the two limiting holes 1010 respectively to form an axial limiting guide structure, which strictly limits the movement direction of the suspension auxiliary block 2, allowing it to slide up and down along the axis, preventing it from rotating circumferentially or shifting radially, and ensuring that the lower insulating sheet 203, conductive sheet 207, and upper insulating sheet 208 on the suspension auxiliary block 2 are always precisely aligned with the conductive block 1013 in the insertion groove 109 of the suspension base 1, ensuring the mechanical reliability of the warning linkage structure and avoiding the failure of the warning circuit due to misalignment.

[0026] The working principle of this embodiment: The infusion bottle is secured between three clamping blocks 101 arranged in a circular array at the top of the suspension base 1. The rubber clamping pads 102 on the inner circumference of the clamping blocks 101 will conform to the outer wall of the infusion bottle, achieving stable clamping of the infusion bottle. When installing the infusion trocar, first pass the trocar rod through the locking hole 205 of the rubber locking block 204 at the axis of the suspension auxiliary block 2. The elastic contraction characteristics of the rubber locking block 204 will wrap and limit the trocar rod, so that the trocar and the suspension auxiliary block 2 form a temporary integrated structure. Then, pass the tip of the trocar through the insertion hole of the suspension base 1. Position 1012 is inserted into the infusion bottle. During this process, the suspension auxiliary block 2 will move upward until its top surface is completely in contact with the bottom surface of the suspension base 1. At this time, the spring connector 202 is compressed and stored in the annular storage groove 1011 of the suspension base 1. At the same time, the lower insulating sheet 203 on the suspension auxiliary block 2 contacts the two conductive blocks 1013 in the insertion groove 109. The conductive sheet 207 and the conductive block 1013 remain separated. The control circuit of the buzzer 105 is in the cut-off state. The device has no warning prompts and the infusion system enters the normal working state. Furthermore, as the suspension auxiliary block 2 moves with the puncture device, the limiting pins 201 on the left and right sides of its top surface will slide axially along the limiting insertion holes 1010 of the suspension base 1. Through the sliding insertion and engagement of the limiting pins 201 and the limiting insertion holes 1010, the movement direction of the suspension auxiliary block 2 is restricted, preventing it from rotating circumferentially. This ensures that the lower insulating sheet 203, the conductive sheet 207, and the upper insulating sheet 208 always maintain a precise alignment with the conductive block 1013 in the insertion slot 109, thus ensuring the reliability of the alarm circuit linkage. If the IV tubing is pulled during a child's intravenous infusion, causing the tubing to pull the trocar rod outward and separating the trocar from the IV bottle, resulting in a downward pulling displacement, the suspension auxiliary block 2 temporarily fixed to the trocar will move downward under the pulling force. This downward movement will cause the lower insulating sheet 203, conductive sheet 207, and upper insulating sheet 208 to slide downward synchronously along the insertion groove 109. This will cause the conductive sheet 207, which was originally close to but not in contact with the two conductive blocks 1013, to move to a position where it is in contact with the two conductive blocks 1013. At the contact point, the control circuit of the buzzer 105 is connected. After receiving the circuit connection signal, the microcontroller 1015 triggers the buzzer 105 to start. The buzzer 105 emits a continuous warning sound to promptly remind medical staff or parents that the puncture device has been displaced and needs to be dealt with immediately to avoid the interruption of drug delivery, backflow of blood and other infusion risks. When the puncture device is reset, the suspension auxiliary block 2 moves upward, the conductive sheet 207 and the conductive block 1013 separate again, the control circuit is cut off, the buzzer 105 stops warning, and the device returns to the initial state. The electrical components of the device are powered by the power supply unit 1014 inside the suspension base 1. The power display 106 on the front cut surface 104 of the suspension base 1 can display the remaining power of the power supply unit 1014 in real time. When the power is insufficient, the power supply unit 1014 can be charged through the charging port 108. The on / off switch 107 is electrically connected to the microcontroller 1015 and can manually control the opening and closing of the entire warning system.
