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 After the catheter has completely entered the blood vessel, the needle core is withdrawn, and only the soft catheter is left in the blood vessel for infusion therapy.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 .
