Description

Technical Field

[0001] This utility model relates to the field of child safety seat technology, specifically a child safety seat suitable for intravenous puncture. Background Technology

[0002] Pediatric intravenous puncture is an indispensable treatment technique in pediatric nursing, playing a key role in the diagnosis, treatment, and monitoring of diseases. However, due to the special physiological structure and psychological characteristics of children, this procedure faces many challenges. Children's veins are usually small and difficult to identify. In addition, children may have difficulty staying still during the puncture process due to fear or discomfort. This not only increases the risk of puncture failure and prolongs the operation time, but may also cause additional pain to the child and increase the workload of medical staff.

[0003] Traditionally, to ensure a smooth puncture procedure, medical staff would manually restrain the child, such as having parents or nurses hold the child to limit their movement. While effective, this method is labor-intensive and carries the risk of injury, and is not always the ideal choice in practice.

[0004] In recent years, with the advancement of medical technology, advanced technologies such as infrared vein scanners have been introduced into clinical practice. These devices utilize the ability of infrared light to penetrate human tissue to clearly map the location, path, and depth of veins, thereby helping to improve the success rate of puncture. However, obtaining clear vein images stably when children are uncooperative remains a challenge, especially when it is necessary to simultaneously fix the child, prepare for puncture, and operate the scanner. This undoubtedly increases the complexity of the work for medical staff and affects efficiency.

[0005] Considering the above factors, we propose a safety seat solution specifically designed for pediatric intravenous puncture. This seat aims to solve the problems existing in the current technology by integrating advanced imaging technology and child psychology principles to provide an environment that can accurately display vein information and attract and soothe children's attention through animations. This simplifies the operation process for medical staff, improves the success rate of puncture, reduces children's fear and discomfort, and also reduces the workload of medical staff. Therefore, we propose a safety seat suitable for pediatric intravenous puncture. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1 - Figure 6 This utility model provides a technical solution:

[0029] A safety seat suitable for children undergoing intravenous puncture includes a seat 1, an asynchronous self-locking stepper motor 2 fixedly installed on the outer wall of the seat 1, a seat stem 3 fixedly installed on the outer side of the output shaft of the asynchronous self-locking stepper motor 2, the asynchronous self-locking stepper motor 2 is started to rotate the seat stem 3, a seat cushion 4 is fixedly installed on the top of the seat stem 3, a seat back 5 is fixedly installed on the outer side of the seat cushion 4, a child sits on the seat cushion 4 and leans against the seat back 5, an armrest 6 is fixedly installed on the end of the seat cushion 4 near the seat back 5, and two sets of armrests 6 are provided.

[0030] In one embodiment of this utility model, a movable component 7 is provided on the outer side of the seat 1. The movable component 7 includes a base 71. A controller 72 and a fixed end of a multi-stage telescopic rod 73 are fixedly installed on the top of the base 71. A mounting bracket 74 is rotatably installed on one side of the piston end of the multi-stage telescopic rod 73. A display device 75 (selected as a mobile phone or tablet computer) is snapped into the mounting bracket 74. An integrated air pump 76 is fixedly installed on the upper surface of the bottom end of the seat 1. The integrated air pump 76 integrates inflation and deflation functions. It changes the flow direction of gas through an internal valve switching device to realize the inflation or deflation operation of the inflatable airbag 79. The output end of the integrated air pump 76 is fixedly connected to one side of a T-shaped tube 77. The other side of the T-shaped tube 77 is fixedly connected to one end of a flexible hose 78. An inflatable airbag 79 is fixedly installed on the other end of the flexible hose 78. The inflatable airbag 79 is fixedly installed on the seat cushion 4. In addition, the soft Two sets of tubing 78 and inflatable airbags 79 are provided, and the two sets of tubing 78 and inflatable airbags 79 are mirror images of each other at both ends of the seat 1, which can clamp and fix the child's buttocks. A hand rest 710 is fixedly installed on the top of the side of the chair stem 3 away from the base 71. The top of the hand rest 710 is fixedly installed at the center of the bottom of the curved cover 711. One end of the curved cover 711 is fixedly connected to one end of the movable hook and loop fastener 712, and the other end of the curved cover 711 is fixedly installed with a fixed hook and loop fastener 713. The other end of the movable hook and loop fastener 712 is attached to the outside of the fixed hook and loop fastener 713. In addition, there are two sets of movable hook and loop fasteners 712 and fixed hook and loop fasteners 713, which provides better fixation for the child's arm to be punctured. An infrared vein scanner 714 is provided on the outside of the hand rest 710 (the infrared vein scanner 714 contains an infrared light source, which emits infrared beams of specific wavelengths, generally in the range of 700- Infrared rays in the 1000-nanometer band can penetrate skin and subcutaneous tissue well. When infrared rays shine on parts of the human body, such as the arm, most of the infrared rays penetrate the skin and muscles, while a small portion is absorbed and scattered by these tissues. During the penetration of infrared rays, when they encounter veins, the transmissibility of infrared rays is significantly reduced because veins contain abundant hemoglobin, which has a strong absorption capacity for infrared rays. In contrast, the surrounding skin and muscles absorb less infrared rays, resulting in higher transmissibility. Therefore, the intensity of infrared rays reflected from veins is weaker than that reflected from surrounding tissues, creating a contrast difference between veins and surrounding tissues in the reflected light. The image sensor converts the received infrared signals into electrical signals, which are then converted into digital signals by an analog-to-digital converter. These digital signals are transmitted to the image processing unit of the scanner. The image processing unit performs a series of processing and analysis on the acquired digital images to highlight the contours and details of the veins. Through these image processing algorithms, a clear image of the veins is finally presented on the scanner's display screen.Medical staff can directly observe the location, direction, and thickness of veins. The 714 infrared vein scanner is existing equipment; therefore, its working principle will not be described in detail here.

[0031] In this embodiment, medical staff operate the controller 72 according to the child's height and actual operational needs. The controller 72 sends a command to the multi-stage telescopic rod 73 to activate it, causing its piston end to extend or retract. As the piston end extends or retracts, the height of the mounting bracket 74 from the ground changes accordingly. When it is necessary to adjust the tilt angle of the display device 75, the medical staff manually rotates the mounting bracket 74. The display device 75, which is snapped into the mounting bracket 74, rotates synchronously with the rotation of the mounting bracket 74, thereby achieving flexible adjustment of the tilt angle of the display device 75. The adjustable design allows the display device 75 to be presented to children at the optimal angle, making it convenient for them to watch cartoons and effectively diverting their attention. Once the child is seated on the cushion 4, medical staff activate the air pump unit 76 via the controller 72. The air pump unit 76 integrates both inflation and deflation functions. The internal valve switching device activates, adjusting the air pump unit 76 to inflation mode. The air pump unit 76 then begins operating, generating high-pressure gas. The gas flows from the output end of the air pump unit 76 into the T-shaped tube 77. The tube 77 diverts the gas, allowing it to be transmitted through two flexible tubes 78 to ensure smooth gas delivery to the inflatable balloon 79. Once the gas enters the inflatable balloon 79, it gradually inflates, expanding from its initial flat state to create uniform pressure on the child's buttocks, effectively clamping and securing the child's body. This prevents the child from moving during the puncture procedure. Medical staff guide the child to gently place the arm to be punctured within the curved cover 711 on the hand support 710, providing comfortable support and restricting lateral movement. The medical staff then pulls the movable Velcro 712 towards the fixed Velcro 713 and attaches it to the outside of the fixed Velcro 713. By adjusting the position and pressure of the attachment, personalized fixation is achieved based on the child's arm thickness, ensuring the arm remains stable during the puncture and preventing interference from arm movements. When the infrared vein scanner 714 starts working, medical staff can visually observe detailed information such as the location, direction, and thickness of the veins, providing a basis for accurately selecting the puncture site.

[0032] After the puncture is completed, the medical staff uses the controller 72 to control the air pump 76 to switch the working mode, changing it from inflation to de-inflation. The air pump 76 begins to extract the gas from the inflatable airbag 79. As the gas is extracted, the inflatable airbag 79 gradually contracts, and the clamping force on the child's buttocks gradually decreases, eventually releasing the fixation on the child's body. The medical staff then unfastens the movable Velcro 712 and the fixed Velcro 713 and removes the child's arm from the curved cover 711.

[0033] In one embodiment of this utility model, an auxiliary component 8 is provided on the outer side of the seat cushion 4. The auxiliary component 8 includes a rectangular plate 81. The rectangular plate 81 is fixedly installed on the upper surface of the bottom of the hand rest 710. The top of the rectangular plate 81 is fixedly connected to the fixed end of the hydraulic cylinder 82. The piston end of the hydraulic cylinder 82 is fixedly connected to the bottom of the rectangular cover 83. A through groove 84 is opened on the side wall of the rectangular cover 83. An asynchronous motor 85 is fixedly installed on the inner wall of the rectangular cover 83. A threaded rod 86 is fixedly installed on the outer side of the output shaft of the asynchronous motor 85. The two ends of the threaded rod 86 are rotatably installed on the inner side of the rectangular cover 83. A threaded block 87 is threadedly installed on the outer side of the threaded rod 86. A slider 89 is fixedly installed on the bottom end of the threaded block 87. A slide rail 88 is fixedly installed on the inner wall of the rectangular cover 83. The slider 89 slides smoothly. Mounted on slide rail 88, a connecting plate 810 is fixedly installed on the top of threaded block 87. The connecting plate 810 passes through through groove 84. Infrared vein scanner 714 is snapped into the inner side of the other end of connecting plate 810. The infrared vein scanner 714 is located directly above the arc-shaped cover 711, thus avoiding the need for medical staff to operate it by hand. While fixing the child and preparing for puncture, the infrared vein scanner 714 also needs to be operated, which reduces the difficulty and workload of medical staff and improves puncture efficiency. In addition, a lamp holder 811 is fixedly installed on the other side of the piston end of multi-stage telescopic rod 73. A lamp 812 is rotatably installed on the lamp holder 811. In addition, a storage slot 813 is opened on the base 71 to store commonly used medical supplies.

[0034] In this embodiment, medical staff activate the asynchronous motor 85 via the controller 72. The output shaft of the asynchronous motor 85 rotates, driving the threaded rod 86, which is fixedly connected to it, to rotate. Under the rotation of the threaded rod 86, the threaded block 87 moves along the axial direction of the threaded rod 86, and the slider 89 slides synchronously on the slide rail 88. As the threaded block 87 moves, the connecting plate 810 at its top also moves. Therefore, the infrared vein scanner 714 moves with the connecting plate 810, thereby adjusting to a suitable position to meet the different observation needs of medical staff, avoiding hand-held operation, and reducing the difficulty and workload of operation for medical staff. The increased intensity of the light fixture improves puncture efficiency. Furthermore, if lighting needs adjustment during the puncture process, medical staff can manually rotate the lamp 812 on the lamp holder 811. The lamp holder 811 provides a support structure for the rotation of the lamp 812, allowing the lamp 812 to rotate at multiple angles around the rotation point on the lamp holder 811, changing the direction of light illumination and providing medical staff with a clear operating field of vision, ensuring the smooth progress of the puncture process. Additionally, medical staff can place commonly used medical supplies, such as cotton swabs and syringes, in the storage compartment 813, facilitating easy access to necessary items during the procedure and improving work efficiency.

[0035] All electrical components mentioned in this application are electrically connected to the controller 72 and the 220V mains power. The controller 72 is a conventional and known device that can control the asynchronous self-locking stepper motor 2, the multi-stage telescopic rod 73, the air pump integrated machine 76, the hydraulic cylinder 82, and the asynchronous motor 85. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all conventional methods such as riveting and welding that are mature in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, and will not be described in detail here.

[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
