Description

Technical Field

[0001] This utility model relates to the field of pediatric intravenous puncture auxiliary devices, and in particular to a pediatric intravenous puncture auxiliary device. Background Technology

[0002] Intravenous infusion is a common treatment for pediatric patients. For children under two years old, the posterior auricular vein, superficial temporal vein, and median frontal vein are usually selected. Scalp veins are the first choice because they are easy to observe, fix, and care for. However, children are naturally active and prone to crying, making it difficult for them to cooperate with medical staff during puncture. Therefore, it is necessary to fix the head of the pediatric patient.

[0003] Common pediatric intravenous puncture assistive devices only include head fixation, which can fix the head of pediatric patients, but lack the function of adjusting the fixation strap. This cannot guarantee that the fixation can be adjusted according to the head circumference of different pediatric patients, and it is easy to have problems with the fixation strap not being able to be adjusted when fixing the head of pediatric patients with different head circumferences, affecting the fixation fit.

[0004] Therefore, to address the lack of adjustable fixing strap functionality in the aforementioned pediatric intravenous puncture auxiliary devices, a pediatric intravenous puncture auxiliary device can be designed. This device uses a rubber head positioning plate to initially position the child patient's head, then starts a motor that drives a winding shaft to rotate. During rotation, the winding shaft winds up the head strap, causing it to retract into the protective frame. The motor stops when the head strap retracts to fit snugly against the child patient's head, thus ensuring that the size of the head strap can be adjusted according to the head circumference of different children. Utility Model Content

[0005] To overcome the common problem of pediatric intravenous puncture auxiliary devices lacking adjustable fixation straps, which cannot guarantee fixation according to different head circumferences of children, the fixation straps are prone to being unadjustable when fixing children with different head circumferences, affecting the fixation fit.

[0007] Preferably, the head of the child patient is initially positioned using a rubber head positioning plate. Then, the motor is started, driving the winding shaft to rotate. During rotation, the winding shaft winds up the head strap, causing it to retract into the protective frame. The motor stops when the head strap retracts to fit snugly against the child patient's head. This ensures that the size of the head strap can be adjusted according to the head circumference of different children. This addresses the common problem of common pediatric intravenous puncture auxiliary devices that only include head fixation function, which can fix the child patient's head but lacks the function of adjusting the fixation strap. This makes it impossible to guarantee fixation according to the head circumference of different children, and it is easy for the fixation strap to be unable to be adjusted when fixing the head of children with different head circumferences, affecting the fixation adaptability.

[0008] Preferably, a limiting groove is provided at the center of the top of the support platform, and an inlet / outlet groove is provided at the middle of the front side of the support platform corresponding to the limiting groove.

[0014] Preferably, a connecting plate is provided in the middle of the right side of the protective frame, and a rubber head positioning plate is provided on the right side of the connecting plate.

[0015] The beneficial effects of this utility model are:

[0016] 1. The rubber head positioning plate is used to initially position the child patient's head. Then, the motor is started, and the motor drives the winding shaft to rotate. During the rotation, the winding shaft winds up the head strap, causing the head strap to retract into the protective frame. The motor stops when the head strap retracts to fit snugly against the child patient's head. This ensures that the size of the head strap can be adjusted according to the head circumference of different children. This addresses the common problem of common pediatric intravenous puncture auxiliary devices that only include head fixation function, which can fix the child patient's head but lacks the function of adjusting the fixation strap. This makes it impossible to guarantee fixation according to the head circumference of different children, and it is easy to have the fixation strap unable to be adjusted when fixing the child's head with different head circumferences, affecting the fixation adaptability.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-5This utility model provides an embodiment: a pediatric intravenous puncture auxiliary device, including a support platform 1; it also includes a support block 2, a mounting plate 3, a motor 4, a winding shaft 5, and a head strap 6. The support block 2 is located on the left side of the top center of the support platform 1, the mounting plate 3 is located on the top of the support block 2, and the motor 4 is located on the right side of the bottom center of the mounting plate 3. The output end of the motor 4 passes through the mounting plate 3 and is connected to the winding shaft 5. The head strap 6 is connected around the winding shaft 5. The child's head is initially positioned by a rubber head positioning plate 19, and then the motor 4 is started, driving the winding shaft 5 to rotate. During rotation, the head strap 6 is rolled up, causing it to retract into the protective frame 15. The motor 4 stops when the head strap 6 retracts to fit snugly against the child patient's head. This ensures that the size of the head strap 6 can be adjusted according to the head circumference of different children. This addresses the common problem of pediatric intravenous puncture auxiliary devices that only include head fixation function, which can fix the child patient's head but lacks the function of adjusting the fixation strap. This makes it impossible to guarantee fixation according to the head circumference of different children, and it is easy for the fixation strap to be unable to be adjusted when fixing the head of children with different head circumferences, affecting the fixation adaptability.

[0025] Please see Figures 2-5 In this embodiment, a limiting groove 7 is provided at the center of the top of the support platform 1, and an inlet / outlet groove 8 is provided at the middle of the front side of the support platform 1 corresponding to the limiting groove 7. A U-shaped support base 9 is provided at the bottom of the support platform 1, and a seat groove 10 is provided at the middle of the bottom of the inner side of the U-shaped support base 9. Four support legs 11 are provided at the four corners of the bottom of the U-shaped support base 9, and self-locking universal pulleys 12 are provided at the bottom of the four support legs 11. The child patient is carried to the U-shaped support base 9 and placed inside the U-shaped support base 9, so that the child patient sits in the seat groove 10. The upper body of the child patient passes through the inlet / outlet groove 8 and enters the limiting groove 7. The seat groove 10 limits the position of the lower body of the child patient, while the limiting groove 7 limits the upper body of the child patient to prevent the child patient's movements from being too large and affecting the treatment.

[0026] Please see Figures 1-5In this embodiment, first triangular reinforcing blocks 13 are symmetrically arranged at the bottom of the left and right sides of the support block 2, and second triangular reinforcing blocks 14 are symmetrically arranged at the front and rear ends of the bottom right side of the mounting plate 3. A protective frame 15 is arranged on the right side of the top of the mounting plate 3 corresponding to the position of the winding shaft 5. A sealing door 16 is movably connected to the left side of the protective frame 15 via a hinge. A tape outlet groove 17 is opened at the right end of the front side of the protective frame 15. The end of the head strap 6 away from the winding shaft 5 passes through the tape outlet groove 17 and is pasted to the rear side of the protective frame 15 with epoxy resin adhesive. A connecting plate 18 is arranged in the middle of the right side of the protective frame 15, and a rubber head positioning plate 19 is arranged on the right side of the connecting plate 18. After the child patient sits down, The child's head is placed against the rubber head positioning plate 19 for initial positioning. Then, the motor 4 is started, driving the winding shaft 5 to rotate. During rotation, the winding shaft 5 winds up the head strap 6, causing it to retract into the protective frame 15. The motor 4 is stopped when the head strap 6 retracts to fit snugly against the child's head. This ensures that the size of the head strap 6 can be adjusted according to the head circumference of different children, thus achieving the function of adjusting the fixation strap and preventing the fixation strap from being unable to be adjusted when fixing children's heads with different head circumferences, which would affect the fixation fit.

[0027] During the procedure, the child patient is carried to the U-shaped support base 9 and placed inside it, sitting in the seat slot 10. The child's upper body passes through the inlet / outlet slot 8 and into the limiting slot 7. The seat slot 10 restricts the position of the child's lower body, while the limiting slot 7 restricts the upper body, preventing excessive movement that could affect the treatment. Once the child is seated, their head is placed against the rubber head positioning plate 19 for initial head positioning. Then, the motor 4 is started, driving the winding shaft 5 to rotate. During rotation, the winding shaft 5 winds up the head strap 6, causing it to retract into the protective frame 15. The motor 4 stops when the head strap 6 is fully retracted and fits snugly against the child's head, thus ensuring that the size of the head strap 6 can be adjusted according to the head circumference of different children, achieving the function of adjusting the fixation strap.

[0028] Through the above steps, the rubber head positioning plate 19 is used to initially position the child patient's head. Then, the motor 4 is started, and the motor 4 drives the winding shaft 5 to rotate. During the rotation, the winding shaft 5 winds up the head strap 6, causing the head strap 6 to retract into the protective frame 15. When the head strap 6 retracts to fit snugly against the child patient's head, the motor 4 is stopped. This ensures that the size of the head strap 6 can be adjusted according to the head circumference of different children. This solves the problem that common pediatric intravenous puncture auxiliary devices only have a head fixation function, which can fix the child patient's head, but lacks the function of adjusting the fixation strap. This makes it impossible to guarantee that the fixation strap can be adjusted according to the head circumference of different children, which easily leads to the problem of the fixation strap not being able to be adjusted when fixing the head of children with different head circumferences, affecting the fixation adaptability.
