Abstract

The invention discloses a disposable non-bent tube indwelling needle which includes a steel needle, a conduit base and an indwelling conduit. A channel for the steel needle to penetrate is arranged inthe conduit base, the inner wall of the indwelling conduit closely adheres to the outer wall of the steel needle, and a soft conduit connecting base is further arranged between the conduit base and the indwelling conduit. In a using state, the position of the top end of the indwelling conduit is higher than that of the bottom end of the soft conduit connecting base. According to the disposable non-bent tube indwelling needle, the problems of pipe bending and blockage caused by palm bending during transfusion are effectively solved, the normal flow velocity of transfusion is ensured, operationsafety is improved, and patients' pain is alleviated.

Description

technical field [0001] The invention relates to a disposable non-folding indwelling needle, which belongs to the field of medical instruments. Background technique [0002] The indwelling needle, also known as the venous trocar, can reduce the pain caused by repeated venipuncture in children and the fear of injections, relieve the anxiety of parents, facilitate clinical medication, and reduce the workload of clinical nurses. The indwelling needle is easy to operate, suitable for puncture at any part, and is widely used in clinical practice. The core components of the indwelling needle include the catheter / cannula indwelling in the blood vessel, and the puncture guide core. When in use, the catheter and the needle core Puncture into the blood vessel together, and after the catheter has completely entered the blood vessel, the needle core is withdrawn, and the catheter is left in the blood vessel for infusion therapy. [0003] Indwelling needles in the prior art, such as fig...
