Description
Technical Field
[0001] This utility model relates to an auxiliary device for vaccination operation, specifically a positioning mechanism for early childhood vaccination operation. Background Technology
[0002] Vaccination of young children is one of the most effective ways to prevent infectious diseases. It can enhance children's immunity and reduce the risk of disease transmission. By vaccinating young children, they can acquire immune protection against specific pathogens, reduce the probability of infection and severe illness, and support the establishment of herd immunity.
[0003] When children are vaccinated, their natural fear causes them to struggle, which can make the injection process difficult for medical staff and may cause the needle to slip. Parents can also forcefully restrain the child, which can make the child feel even more frightened and cause psychological trauma. Therefore, there is an urgent need for a positioning structure for children's vaccination. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides the following technical solution: a positioning mechanism for early childhood vaccination, comprising a seat, a telescopic rod fixedly installed at the bottom of the seat, a counterweight base fixedly installed at the bottom end of the telescopic rod, height-adjustable components on both sides of the seat, an arm support plate for placing the child's arm installed on the top of the height adjustment components, a sponge pad at the top side of the arm support plate where it contacts the child's arm, a strap for securing the arm by tearing and adhesive on the outer side of the arm support plate, and a guide for guiding and limiting the arm between the bottom end of the arm support plate and the seat, a bracket fixedly installed at the front center of the seat, and a smart touch screen installed on the top of the bracket. By placing the child's arm on the arm support plate, the strap can be torn and secured to the outside of the child's arm. Simultaneously, the smart touch screen plays cartoon animations to attract the child's attention, and finally, the child can be vaccinated. By diverting attention, the child's arm can be quickly secured for vaccination, greatly alleviating the child's fear and preventing excessive struggle.
[0005] As an optimization, the bandage is an elastic bandage, with one end fixedly installed on the bottom side of the arm support plate and the other end provided with Velcro for adhesive fixation.
[0006] As an optimization, a cotton pad is provided on the side of the free end of the hoop that contacts the child's arm to avoid hard contact that could cause injury to the child's arm.
[0007] As an optimization, the guide is composed of a limiting cylinder and a limiting rod, and the limiting rod is slidably inserted into the limiting cylinder. The limiting cylinder is fixedly installed on the side of the seat, and the top end of the limiting rod is fixedly installed on the bottom end of the arm support plate.
[0008] As an optimization, the height adjustment assembly includes a fixed cylinder fixedly installed on the side of the seat, a threaded cylinder slidably inserted inside the fixed cylinder, and the top of the threaded cylinder fixedly installed on the bottom side of the middle of the arm support plate. A screw is rotatably connected inside the middle of the fixed cylinder, and the screw is screwed into the center of the threaded cylinder. A limit strip is fixedly installed on the outer side of the threaded cylinder, and a limit groove is opened on the inner wall of the fixed cylinder corresponding to the limit strip. The limit strip is slidably inserted into the limit groove. A transmission component for driving the screw to rotate is provided at the bottom of the fixed cylinder.
[0009] As an optimization, the transmission component includes an outer cylinder seat fixedly installed on the outer side of the bottom of the fixed cylinder, a worm gear rotatably connected inside the outer cylinder seat, a worm wheel rotatably connected inside the bottom of the fixed cylinder, and the worm wheel and the worm gear meshing together, a screw fixedly installed at the top center of the worm wheel, a crank fixedly installed at one end of the front of the worm gear, and a rotating shaft fixedly and rotatably connected at the bottom center of the worm wheel, and the rotating shaft rotatably connected inside the bottom of the fixed cylinder.
[0010] As an optimization, the part of the arm support plate that supports the child's forearm is angled inward at 15°. By tilting the child's forearm, the deltoid muscle is naturally exposed, making it easier for medical staff to perform injections.
[0011] The beneficial effects of this utility model are as follows: This positioning mechanism for early childhood vaccination can be tightened and positioned by a tear-off adhesive strap that is placed on the outside of the child's arm. Because the arm support plate supports the child's forearm at a 15° inward angle, the forearm is tilted, naturally exposing the deltoid muscle, thus facilitating injection for medical personnel. The tear-off adhesive strap also provides quick and easy arm fixation. Furthermore, by playing cartoons on a smart touchscreen, the mechanism attracts the child's attention, quickly fixing the arm for vaccination by diverting their focus, greatly alleviating their fear and minimizing excessive struggling. When the crank handle rotates the worm gear, the worm wheel drives the screw to rotate inside the threaded cylinder. Because the limiting strip slides into the limiting groove, restricting the rotation of the threaded cylinder, the cylinder rises and falls vertically along the inner wall of the fixed cylinder, adjusting the height of the arm support plate. This allows for adjustments to the arm support height to suit children of different sizes, improving practicality. Attached Figure Description

[0017] The technical solutions in the embodiments of this utility model will be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0018] Please see Figure 1 A positioning mechanism for early childhood vaccination includes a seat 1, a telescopic rod 2 fixedly installed at the bottom of the seat 1, a counterweight base 3 fixedly installed at the bottom end of the telescopic rod 2, and height-adjustable components 4 on both sides of the seat 1. An arm support plate 5 for placing the child's arm is installed on the top of the height-adjustable components 4. The part of the arm support plate 5 that supports the child's forearm is angled inward at 15°, allowing the deltoid muscle to be naturally exposed by tilting the child's forearm, facilitating injection by medical personnel. A sponge pad is provided on the top side of the arm support plate 5 where it contacts the child's arm, and the outer side of the arm support plate 5 has a tear-and-adhesive... The arm is secured with a strap 6, and a guide is provided between the bottom end of the arm support plate 5 and the seat 1 for guiding and limiting. A bracket 7 is fixedly installed in the middle of the front end of the seat 1, and a smart touch screen 8 is installed on the top of the bracket 7. By placing the child's arm on the arm support plate 5, the strap 6 can be pulled to secure the child's arm. At the same time, the smart touch screen 8 is turned on to play cartoons to attract the child's attention. Finally, the child can be vaccinated. By diverting attention, the child's arm can be quickly secured for vaccination, which can greatly alleviate the child's fear and prevent the child from struggling due to excessive fear.
[0019] Please see Figure 2 The bandage 6 is an elastic bandage 9, with one end fixedly installed on the bottom side of the arm support plate 5, and the other end provided with Velcro for fastening. The free end of the bandage 6 has a cotton pad 10 on the side that contacts the child's arm to avoid hard contact that could damage the child's arm. The Velcro fastening method allows for quick and easy fixation of the child's arm. After vaccination, the fixation can be canceled simply by tearing off the free end of the bandage 9, which is convenient and quick.
[0020] Please see Figure 2 The guide component consists of a limiting cylinder 11 and a limiting rod 12. The limiting rod 12 is slidably inserted into the limiting cylinder 11. The limiting cylinder 11 is fixedly installed on the side of the seat 1. The top end of the limiting rod 12 is fixedly installed on the bottom end of the arm support plate 5. When the height of the arm support plate 5 is adjusted by the height adjustment component 4, the limiting rod 12 will slide inside the limiting cylinder 11, thereby playing a guiding and limiting role, so that the arm support plate 5 remains vertically raised and lowered.
[0021] Please see Figure 3-4 The height adjustment component 4 includes a fixed cylinder 13 fixedly installed on the side of the seat 1. A threaded cylinder 14 is slidably inserted into the inside of the fixed cylinder 13, and the top of the threaded cylinder 14 is fixedly installed on the bottom side of the middle part of the arm support plate 5. A screw 15 is rotatably connected to the middle part of the fixed cylinder 13, and the screw 15 is screwed into the center of the threaded cylinder 14. A limiting strip 16 is fixedly installed on the outside of the threaded cylinder 14. A limiting groove 17 is opened on the inner wall of the fixed cylinder 13 corresponding to the limiting strip 16, and the limiting strip 16 is slidably inserted into the limiting groove 17. A transmission component is provided at the bottom of the fixed cylinder 13 to drive the screw 15 to rotate. The transmission component can drive the screw 15 to rotate inside the threaded cylinder 14. Since the limiting strip 16 is slidably inserted into the limiting groove 17 to restrict the rotation of the threaded cylinder 14, the threaded cylinder 14 will rise and fall vertically along the inner wall of the fixed cylinder 13, thereby adjusting the height of the arm support plate 5. This makes it convenient to adjust the position of the arm support height according to the different body sizes of children, improving practicality.
[0022] Please see Figure 3-4 The transmission component includes an outer cylinder seat 18 fixedly installed on the outer side of the bottom of the fixed cylinder 13. A worm 19 is rotatably connected inside the outer cylinder seat 18. A worm wheel 20 is rotatably connected inside the bottom of the fixed cylinder 13, and the worm wheel 20 and the worm 19 are meshed together. A screw 15 is fixedly installed at the top center of the worm wheel 20. A crank handle 21 is fixedly installed at one end of the front of the worm 19. A rotating shaft 22 is fixedly rotatably connected to the bottom center of the worm wheel 20, and the rotating shaft 22 is rotatably connected inside the bottom of the fixed cylinder 13. By turning the crank handle 21, the worm 19 can be rotated, which in turn will drive the screw 15 to rotate through the worm wheel 20 meshing with the worm 19. Thus, the height of the height adjustment component 4 can be adjusted by transmission.
[0023] When using it, first place the child on seat 1, then turn on the smart touch screen 8 to play cartoons to attract the child's attention. Then place the child's arm on the arm support plate 5 and stretch the bandage 9 to put it on the outside of the child's arm. Then use Velcro to restrict and position the free end of the bandage 9, so that the child's arm can be tightened and positioned. After that, the child's arm can be injected with the vaccine.
[0024] The worm gear 19 can be rotated by turning the crank handle 21, which in turn drives the screw 15 to rotate through the worm wheel 20 that meshes with the worm gear 19. The screw 15 rotates inside the threaded cylinder 14, and the limiting strip 16 slides into the limiting groove 17 to restrict the rotation of the threaded cylinder 14. This causes the threaded cylinder 14 to rise and fall vertically along the inner wall of the fixed cylinder 13, thereby adjusting the height of the arm support plate 5.
[0025] In summary, this positioning mechanism for immunization procedures for young children can be secured and positioned by attaching a tear-off adhesive band 6 to the outside of the child's arm. Because the part of the arm support plate 5 that supports the child's forearm is angled inward at 15°, the child's forearm will be tilted, naturally exposing the deltoid muscle, which further facilitates the injection by medical staff. Moreover, the tear-off adhesive band 6 makes it easy and quick to fix the arm.
[0026] By turning on the smart touchscreen 8 to play cartoons to attract children's attention, and by diverting their attention to quickly fix their arms for vaccination, the children's fear can be greatly alleviated and excessive struggle can be avoided.
[0027] When the crank handle 21 is turned to drive the worm gear 19 to rotate, the worm wheel 20 will drive the screw 15 to rotate inside the threaded cylinder 14. Since the limiting strip 16 is slidably inserted into the limiting groove 17 to restrict the rotation of the threaded cylinder 14, the threaded cylinder 14 will rise and fall vertically along the inner wall of the fixed cylinder 13, thereby adjusting the height of the arm support plate 5. This allows for easy adjustment of the arm support height position according to the different body sizes of children, improving practicality.
