Therefore, intravenous catheters are widely used in clinical pediatrics. At present, children only use medical 3M patches for simple fixation after the indwelling catheter is done, but the indwelling needles used for newborns are straight needles. The material of the needle wings is relatively hard and directly contacts the child's skin. It is affected by friction and shear force, which is prone to pressure sores or injuries.
[0003] The existing fixing device directly uses an elastic bandage to restrain and fix the indwelling needle. There is no protective structure under the handle of the indwelling needle. The elastic bandage applies pressure to the handle of the indwelling needle, and the handle of the indwelling needle is directly pressed on the skin. Children's skin is delicate. Long-term use of the elastic bandage can easily cause the handle of the indwelling needle to press the child's skin, thereby reducing the fixation effect of the indwelling needle and failing to meet the use requirements.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0021] See also Figure 1-4 The utility model provides an embodiment: an auxiliary fixing device for an indwelling needle, comprising a dressing sheet 1, an indwelling needle 2 and an elastic bandage 4, wherein the dressing sheet 1 is arranged below the indwelling needle 2, and further comprising:
[0022] A Velcro hook surface 5 is arranged on the inner side of one end of the elastic bandage 4, and a Velcro fleece surface 6 is arranged on the outer side of the other end of the elastic bandage 4. The Velcro hook surface 5 and the Velcro fleece surface 6 are connected to the elastic bandage 4 as a whole, and the Velcro hook surface 5 and the Velcro fleece surface 6 are arranged correspondingly.
[0023] During use: after inserting the indwelling needle 2 into the skin, disassemble the dressing sheet 1 and lay it flat against the skin, place the handle of the indwelling needle 2 flat on the dressing sheet 1, connect the two ends of the elastic bandage 4 around the palm through the Velcro hook surface 5 and the Velcro fleece surface 6, and restrain and fix the indwelling needle 2 through the elastic bandage 4. The dressing sheet 1 protects the skin under the handle of the indwelling needle to prevent the handle of the indwelling needle from pressing on the skin for a long time, causing the skin to become red or broken.
[0024] See also Figure 1 and Figure 2 A slope 3 is provided at one end of the dressing sheet 1, and the inclination angle of the slope 3 is set to fifteen degrees. The cross-section of the dressing sheet 1 is set to be rectangular, and the width of the dressing sheet 1 is set to be greater than the length of the handle of the indwelling needle. The slope 3 guides the contact part of the indwelling needle 2 with the skin, so that the handle of the indwelling needle can be placed flat on the dressing sheet 1.
[0025] See also Figure 2 and Figure 4The dressing sheet 1 includes a sterile cotton layer 9 and a skin-friendly sweat-absorbent layer 10. The sterile cotton layer 9 is arranged above the skin-friendly sweat-absorbent layer 10, and the sterile cotton layer 9 and the skin-friendly sweat-absorbent layer 10 are arranged as a whole. The thickness of the dressing sheet 1 is set to 0.5 mm. The sterile cotton layer 9 makes the dressing sheet 1 sterile, which can reduce bacterial infection. The skin-friendly sweat-absorbent layer 10 contacts the skin and can absorb the sweat generated in the contact area, thereby improving the comfort of the dressing sheet 1 fitting the skin.
[0026] See also Figure 3 A thumb opening 11 is provided on the elastic bandage 4, and a cotton loop 12 is provided inside the thumb opening 11, and the cotton loop 12 is connected to the elastic bandage 4 as a whole. When the elastic bandage 4 is used to restrain the indwelling needle 2, the patient's thumb is passed through the thumb opening 11, which limits the restrained elastic bandage 4 and prevents the elastic bandage 4 from sliding toward the wrist. The cotton loop 12 protects the base of the thumb and prevents skin damage at the base of the thumb.
[0027] See also Figure 3 A cotton pad 7 is provided in the middle part of the elastic bandage 4, and the cotton pad 7 is closely connected to the elastic bandage 4. The cotton pad 7 is provided corresponding to the indwelling needle 2. When the elastic bandage 4 restrains and fixes the indwelling needle 2, the cotton pad 7 contacts the indwelling needle 2, and there is a flexible contact between the indwelling needle 2 and the elastic bandage 4, which also plays a protective role for the restrained and fixed indwelling needle 2.
[0028] See also Figure 3 The elastic bandage 4 is provided with ventilation holes 8, at least six ventilation holes 8 are provided, and the ventilation holes 8 are arranged equidistantly on the elastic bandage 4. The ventilation holes 8 are arranged through the elastic bandage 4, so that air can flow inside and outside the elastic bandage 4, ensuring air circulation around the indwelling needle 2, and preventing the air from not circulating around the indwelling needle 2 and accelerating bacterial growth.
[0029] Working principle: After the indwelling needle 2 is inserted into the skin, the dressing sheet 1 is disassembled and placed on the skin, the handle of the indwelling needle 2 is placed flat on the dressing sheet 1, the patient's thumb passes through the thumb opening 11, and the two ends of the elastic bandage 4 are connected around the palm through the Velcro hook surface 5 and the Velcro fleece surface 6, and the indwelling needle 2 is bound and fixed by the elastic bandage 4, the cotton pad 7 is in contact with the indwelling needle 2, and the indwelling needle 2 and the elastic bandage 4 are in flexible contact, which also protects the bound and fixed indwelling needle 2; the dressing sheet 1 protects the skin under the handle of the indwelling needle to prevent the handle of the indwelling needle from pressing the skin for a long time. The sterile cotton layer 9 makes the dressing sheet 1 sterile, which can reduce bacterial infection; the skin-friendly sweat-absorbing layer 10 contacts the skin, and can absorb the sweat produced in the contact part, thereby improving the comfort of the dressing sheet 1 against the skin; the ventilation holes 8 allow air to flow inside and outside the elastic bandage 4, ensuring air circulation around the indwelling needle 2, and preventing the air from not circulating around the indwelling needle 2 and accelerating bacterial growth. The dressing sheet 1 can be used for more than 7 days, and the dressing sheet 1 is independently packaged. The elastic bandage 4 can be used for a long time without changing its elasticity, thereby preventing the restrained indwelling needle 2 from contacting the skin more and more tightly.
