technical field

The utility model relates to the technical field of medical equipment, in particular to a stable and anti-falling indwelling needle.

Background technique

The indwelling needle is to puncture the catheter and the needle core into the blood vessel together. When the catheter has completely entered the blood vessel, the needle core is withdrawn, and only the soft catheter is left in the blood vessel for infusion therapy, so that patients who need continuous infusion do not need to be in the blood vessel. The vein is pricked every time the infusion is given;

When the indwelling needle is inserted into the patient, a sterile transparent sticker will be used to fix the puncture point as the center to keep the puncture point clean and dry. At the same time, the hose part of the indwelling needle will be pasted on the wrist through adhesive tape, And this kind of fixation method, after the patient carries out the normal activity of hand or washes up, easily makes adhesive plaster lose viscosity gradually, makes flexible tube fall off easily from hand-in-hand, and then easily makes delivery catheter displacement in vein, thus, makes delivery catheter Blockage and other situations occur, making it difficult to carry out normal liquid medicine delivery.
