Description

A convenient and fixed indwelling needle

technical field

The utility model relates to the field of medical technology, in particular to a convenient and fixed indwelling needle.

Background technique

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 After the catheter has completely entered the blood vessel, the needle core is withdrawn, and only the soft catheter is left in the blood vessel for infusion therapy. Indwelling needles are divided into open type and closed type, the open type is divided into common type and safe type (needle-stick prevention type), and the closed type is divided into normal type and safe type (needle-stick prevention type).

Catheters are suitable for intermittent, continuous or daily intravenous infusion therapy. The use of scalp needles should be limited to short-term or single-dose administration to collect blood samples or infuse blood and blood products, and the infusion fluid for hemodynamic monitoring is at or near isotonic state and normal pH range (stimulant drugs: only intermittent boluses). The indwelling needle is easy to puncture, and the relevant puncture techniques are easy to learn. Protect the patient's blood vessels, relieve the patient's pain, feel comfortable, improve patient satisfaction and nursing quality. There are many different structure products to choose from, and catheters of different lengths are available to improve nurses' working efficiency. Reasonable drug use , to avoid multiple intermittent infusions every day, reduce puncture and not take medication on time, avoid drug reactions, reduce costs, and reduce the cost of exudation treatment caused by scalp needle puncture.

At present, indwelling needles are used in many special needs wards, but the indwelling needles are easy to fall off during use, especially during long-term use. After the patient's skin sweats, the adhesive stickers that fix the indwelling needles are likely to fail, resulting in the indwelling needles falling off. When the indwelling needle is in use, the hose is easy to bend and cause blockage, and when some patients use the indwelling needle, the arm that fixes the indwelling needle is easy to turn over and move around, causing the indwelling needle on the back of the hand to be rubbed off, which brings a certain degree of pain. There are potential safety hazards, so a convenient and fixed indwelling needle is designed.
