Technical Field

[0001] This utility model belongs to the field of medical device technology, and specifically relates to a restraint and protection device for scalp vein puncture in infants and young children. Background Technology

[0002] During scalp vein puncture in infants and young children, due to their young age and difficulty in cooperating with the procedure, puncture failure is often caused by crying, head and limb shaking, requiring repeated attempts. This not only increases the pain of the infants and young children but also increases the difficulty of the work for medical staff. Currently, the traditional restraint methods mainly include manual pressure and wrapping with a cloth sheet.

[0003] However, these methods have drawbacks such as unstable head fixation, inability to restrict the infant's head movement in three dimensions, affecting the accuracy of puncture; excessively tight restraint of the limbs may cause skin damage to the infant, while excessively loose restraint will not achieve the desired effect; when using these traditional restraint methods, the operator often needs additional personnel to complete the puncture operation; and in the case of a single person on duty, the puncture efficiency is low because family members usually do not know the correct fixation method. Therefore, this application provides a restraint and protection device for infant scalp vein puncture to meet the needs.

[0004] Therefore, it is necessary to design a restraint and protection device for scalp vein puncture in infants and young children to solve the above-mentioned technical problems. Summary of the Invention

[0005] To address the above-mentioned technical problems, this utility model proposes an infant scalp vein puncture restraint protection device to solve the technical problems of unstable head fixation, easy damage or failure of limb restraint, need for additional personnel assistance, and low efficiency of traditional restraint methods.

[0006] The technical solution of this utility model is: This utility model proposes a restraint and protection device for scalp vein puncture in infants and young children, including a head-fixing soft pillow and a restraint soft blanket detachably connected to the head-fixing soft pillow. The top of the head-fixing soft pillow has a C-shaped groove, and the left and right sides of the C-shaped groove have adjustable ear avoidance grooves. The restraint soft blanket has a restraint system on the left and right sides and the top, and the restraint system is equipped with a dynamic pressure monitoring alarm mechanism.

[0009] Preferably, the restraint system consists of Velcro fastening straps fixedly connected to the sides of the restraint soft pack, with an adhesive part corresponding to the Velcro fastening strap at the bottom of the restraint soft pack and Velcro limb fastening straps fixedly connected to the top of the restraint soft pack.

[0010] Preferably, the pressure of the Velcro limb fixation straps is ≤20mmHg.

[0011] Preferably, the dynamic pressure monitoring and alarm mechanism is a piezoelectric sensor built into the Velcro limb fixation strap, and the Velcro limb fixation strap is equipped with an LED indicator light that works with the piezoelectric sensor. When the pressure of the Velcro limb fixation strap exceeds the limit, the LED indicator light will automatically sound an alarm.

[0012] Preferably, the head-fixing soft pillow is made of medical-grade silicone outer layer and memory foam inner core, and its C-shaped groove depth is 3-5cm.

[0021] To enable those skilled in the art to better understand this utility model, the present utility model will now be further described in conjunction with specific embodiments.

[0022] Example 1: like Figures 1-5As shown, this utility model provides a restraint and protection device for scalp vein puncture in infants and young children, including a head-fixing soft pillow 1 and a restraint soft blanket 2 detachably connected to the head-fixing soft pillow 1. The head-fixing soft pillow 1 is made of medical-grade silicone outer layer and memory foam inner core. The restraint soft blanket 2 has a multi-layer composite structure, with an outer layer of antibacterial and breathable knitted fabric, a middle layer of replaceable absorbent cotton pad, and an inner layer of skin-friendly pure cotton. The top of the head-fixing soft pillow 1 has a C-shaped groove 102 with a depth of 3-5cm, which can fit well with the head and neck of infants and young children and restrict head movement. Adjustable ear avoidance grooves 103 are provided on both the left and right sides inside the C-shaped groove 102. The device has two movable cavities 108, which are symmetrically distributed around the head-fixing soft pillow 1. A steel wire rope 109 is fixedly connected to the inner wall of each movable cavity 108 at a point corresponding to the ear avoidance groove 103. A knob tightening device 105 is fixedly connected to both sides of the head-fixing soft pillow 1. The end of the steel wire rope 109 away from the ear avoidance groove 103 is connected to the knob tightening device 105. By rotating the knob tightening device 105, the steel wire rope 109 is wound inside the knob tightening device 105, tightening the steel wire rope 109 and causing the steel wire rope 109 to exert a pulling force on the groove wall of the ear avoidance groove 103. This can be adjusted according to the different head circumferences of infants and young children to avoid compressing the ears.

[0023] The restraint blanket 2 is equipped with restraint systems on its left, right, and top sides. The restraint systems are Velcro fastening straps 203 fixedly connected to the sides of the restraint blanket 2. The bottom of the restraint blanket 2 away from the Velcro fastening straps 203 has an adhesive part 205 corresponding to the Velcro fastening straps 203. The top of the restraint blanket 2 is fixedly connected with Velcro limb fixation straps 206. The Velcro limb fixation straps 206 are equipped with a dynamic pressure monitoring alarm mechanism. The pressure of the Velcro limb fixation straps 206 is ≤20mmHg. When in use, the infant's limbs are fixed by Velcro fastening the Velcro limb fixation straps 206, which can not only restrain the infant, but also prevent pressure injury to the infant.

[0024] The dynamic pressure monitoring and alarm mechanism is a piezoelectric sensor 204 built into the Velcro limb fixation strap 206. The Velcro limb fixation strap 206 is equipped with an LED indicator light that works with the piezoelectric sensor 204. The piezoelectric sensor 204 can monitor the pressure of the restraint strap in real time. When the pressure exceeds 20 mmHg, the LED indicator light will automatically light up to remind medical staff to adjust the tightness of the Velcro limb fixation strap 206 in time.

[0025] The head-fixing soft pillow 1 has anti-slip texture 101 at the bottom, which can increase the friction between it and the operating table, so that the soft pillow remains stable during operation and is not easy to slip. The side wall of the head-fixing soft pillow 1 has an instrument slot 104, which can be used to store instruments such as tourniquets and cotton swabs required for puncture, making it convenient for medical staff to access them.

[0026] The bottom of the head-fixing soft pillow 1 is fixedly connected to a zipper connection end 107. The restraint soft blanket 2 is fixedly connected to a zipper connection end 202 at a location corresponding to the zipper connection end 107. The restraint soft blanket 2 is connected to the zipper connection end 107 via a detachable zipper through the zipper connection end 202.

[0027] The restraint soft pad 2 is fixedly connected to a buckle mounting strap 201 at one end near the head-fixing soft pillow 1. The top of the head-fixing soft pillow 1 has a buckle mounting part 106, and the buckle mounting strap 201 is buckled to the buckle mounting part 106.

[0028] The head-fixing soft pillow 1 and the restraint soft blanket 2 can be detachably connected using both buckles and zippers.

[0029] Working principle: When using this device for scalp vein puncture in infants, first place the head-fixing soft pillow 1 on the operating table and fix it by the anti-slip texture 101 on the bottom. Connect it to the buckle mounting part 106 by the buckle mounting strap 201. Connect the zipper connection end 107 and the zipper connection end 202 to connect the restraint soft blanket 2 to the head-fixing soft pillow 1. Then place the infant on the restraint soft blanket 2 and adjust the infant's position so that the head is placed in the ear relief groove 103 of the head-fixing soft pillow 1. At the same time, rotate the two knob tightening devices 105 according to the infant's head circumference to wind up the steel wire rope 109 inside the movable cavity 108. This will pull the groove wall of the ear relief groove 103 into the movable cavity 108, making the space between the two ear relief grooves 103 larger, thereby adjusting the ear relief grooves 103 and avoiding pressure on the ears.

[0030] Next, use the Velcro limb fixation straps 206 to fix the infant's limbs. During the fixation process, the piezoelectric sensor 204 will monitor the pressure of the Velcro limb fixation straps 206 on the infant's limbs in real time and observe the LED indicator light to ensure that the pressure does not exceed 20 mmHg. Then, the Velcro fixation straps 203 on both sides of the restraint soft blanket 2 are connected and pasted to the adhesive part 205 to fix both sides of the restraint soft blanket 2, completing the overall restraint of the infant. Medical staff can then take the necessary instruments from the instrument slot 104 to perform puncture operations.

[0031] The above are merely preferred embodiments of the present utility model and do not limit the patent scope of the present utility model. All equivalent changes and modifications made within the scope of the present utility model shall still fall within the scope of the present utility model.
