Description

Remaining needle convenient to fix

Technical Field

The utility model relates to the technical field of medical treatment, in particular to an indwelling needle convenient to fix.

Background

Venous indwelling needles are also known as venous trocars. The core components include a flexible catheter/cannula that can be left in the blood vessel, and a stainless steel puncture guide needle. When in use, the catheter and the needle core are punctured into the blood vessel together, and after the catheter completely enters the blood vessel, the needle core is withdrawn, and only the soft catheter is remained in the blood vessel, so that transfusion treatment is carried out. The indwelling needle is classified into an open type and a closed type, the open type is classified into a general type and a safe type (needle penetration prevention), and the closed type is classified into a general type and a safe type (needle penetration prevention).

The indwelling needle is suitable for intermittent, continuous or daily intravenous infusion treatment. The use of scalp steel needles should be limited to short-term or single dose administration to collect blood samples or infuse blood, blood products, hemodynamic monitoring infusion fluids at or near isotonic, normal PH range (irritant drugs: only intermittent bolus). The indwelling needle is easy to puncture, the related puncture technology is easy to learn and protect blood vessels of a patient, pain of the patient is relieved, the patient feels comfortable, the satisfaction degree of the patient is improved, the nursing quality is improved, a plurality of different structural products can be selected, catheters with different lengths can be selected for improving the working efficiency of nurses, reasonable medicine usage is avoided, puncture is reduced and medicine is not used on time when infusion is intermittently performed for a plurality of times every day, reaction among medicines is avoided, cost is reduced, and the cost of exudation treatment caused by scalp needle puncture is reduced.

At present, a plurality of special needs are used in the ward, but the detained needle is easy to fall off when in use, especially when long-term use is carried out, the skin of a patient is easy to cause the fixed adhesive plaster of the detained needle to lose efficacy after sweating, thereby causing the detained needle to fall off, the hose is easy to bend and cause blockage when in use, and certain patients are easy to overturn and tamper the arm of the fixed detained needle when using the detained needle, thereby causing the detained needle on the back of the hand to be rubbed and fall off, bringing a certain potential safety hazard, and therefore, the detained needle convenient to fix is designed.
