Description

Transfusion needle

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to infusion syringe needle.

Background

The needle handle of the clinical disposable infusion set needle is flat and is in the same plane with the needle body. When a nurse inserts the needle, the nurse generally stretches the skin with the left hand, holds the needle handle with the thumb and the forefinger of the right hand, makes the inclined plane of the needle point face upwards, penetrates into the skin from the upper part or the side part of the vein at an angle of 15-30 degrees, and then slides along the direction of the vein to penetrate into the vein. The existing needle handle is easy to shake front and back, left and right when a nurse punctures, particularly, a low-age nurse has unstable needle holding and can not master the needle inserting angle and direction, thereby causing puncture failure and increasing the pain of a patient. After the puncture is successful, the needle head cannot be fixed immediately, a doctor needs to press the needle head and take or paste the adhesive tape at the same time, the operation is very inconvenient, and the needle head is easy to slide or rotate because the needle handle is not fixed in the process.
