Problems solved by technology

[0003] In the clinical use of the prior art, medical adhesive tape is usually used for pasting and fixing, but often due to non-standard and inconsistent fixing methods, the indwelling needle is not fixed firmly or is too tight, causing the indwelling needle to slip easily, the indwelling needle to block the tube, and the indwelling needle to return. Serious consequences such as thrombophlebitis and even blood vessel blockage may endanger the life safety of patients in severe cases

Embodiment 1

[0033] see Figure 1-2 , the present invention provides a secondary fixation method for indwelling needles, including a Y-shaped indwelling needle 1 and an adhesive tape 2. The Y-shaped indwelling needle 1 includes a Y-shaped catheter 3, an attached tube 4 and a heparin cap 5, and the secondary fixation The method includes the following steps:

[0034] Step S1: puncture the patient with the needle of Y-shaped indwelling needle 1;

[0035] Step S2: Cutting the medical adhesive tape to form the adhesive tape 2, the adhesive tape 2 is an I-shaped adhesive tape, and the I-shaped adhesive tape is formed by cutting two opposite "T"-shaped gaps along the edge of the long side of the rectangular adhesive tape. Adhesive tape comprises sticking pressure part 6 and " concave " font part 7 that is positioned at sticking pressure part 6 both sides, and the length of glyph adhesive tape is 7cm, and width is 4cm, and the width of described sticking pressure part 6 along tape width direction...

Embodiment 2

[0039] see Figure 3-4 , the present invention provides a secondary fixation method for indwelling needles, including a Y-shaped indwelling needle 1 and an adhesive tape 2. The Y-shaped indwelling needle 1 includes a Y-shaped catheter 3, an attached tube 4 and a heparin cap 5, and the secondary fixation The method includes the following steps:

[0040] Step S1: puncture the patient with the needle of Y-shaped indwelling needle 1;

[0041] Step S2: cutting the medical adhesive tape to form the sticky pressure tape 2, the sticky pressure tape 2 is an inline tape for standby, and the inline tape is formed by cutting an inline gap 8 along the midline of the long side direction of the rectangular tape, and the length of the inline tape is 9cm, width is 3cm, and the length of described inline notch 8 is 3.0cm;

[0042] Step S3": The in-line gap 8 of the in-line tape passes through the attached tube 4 and wraps the heparin cap to form an "Ω" ring for adhesion, and the other parts a...

Embodiment 3

[0045] see Figure 5 , the present invention provides a secondary fixation method for indwelling needles, including a Y-shaped indwelling needle 1 and an adhesive tape 2. The Y-shaped indwelling needle 1 includes a Y-shaped catheter 3, an attached tube 4 and a heparin cap 5, and the secondary fixation The method includes the following steps:

[0046] Step S1: puncture the patient with the needle of Y-shaped indwelling needle 1;

[0047]Step S2: Cutting the medical tape to form the adhesive tape 2. The adhesive tape 2 is an I-shaped tape and a straight tape for use. The I-shaped tape is formed by cutting two opposite "T"-shaped gaps along the long edge of the rectangular tape. , the I-shaped adhesive tape includes a sticky pressure part 6 and "concave" shaped parts 7 located on both sides of the sticky pressure part 6, and the straight-shaped adhesive tape is a rectangular tape that cuts an inline notch 8 along the midline of the long side direction to form an I-shaped adhesiv...

Abstract

The invention provides a secondary fixing method of an indwelling needle. The indwelling needle comprises a Y-shaped indwelling needle and an adhesive pressing tape, wherein the Y-shaped indwelling needle comprises a Y-shaped catheter, an attached tube and a heparin cap. The secondary fixing method comprises the following steps: S1, performing puncture treatment on a patient by using a needle headof the Y-shaped indwelling needle; S2, cutting a medical adhesive tape to form the adhesive pressing tape, wherein the adhesive pressing tape is an I-shaped adhesive tape and/or a linear adhesive tape for later use; S3, enabling the I-shaped adhesive tape to penetrate through the heparin cap and/or the linear adhesive tape to adhere and press the Y-shaped catheter; and S4, fixing an extension tube of the Y-shaped indwelling needle by using the adhesive pressing tape. The secondary fixing method of the indwelling needle is standard in fixing mode, simple, easy to operate, firm in fixing and reasonable in tightness.

Description

technical field [0001] The invention relates to the technical field of medical aids, in particular to a secondary fixation method for indwelling needles. Background technique [0002] The intravenous indwelling needle is also called the intravenous trocar. The components of the core include a flexible catheter / cannula that can be indwelled in the blood vessel, and a stainless steel puncture guide core. When in use, the catheter and the needle core are punctured into the blood vessel together. After the catheter has completely entered the blood vessel, the needle core is withdrawn, and only the soft catheter is left in the blood vessel for infusion therapy. The use of indwelling needles can reduce the pain caused by repeated venipuncture and the fear of injections, reduce the anxiety of family members, facilitate clinical medication, rescue medication for acute and critical patients, reduce the workload of nurses, and reduce the pain of patients . [0003] In the clinical ...
