Description

Multifunctional remaining needle

Technical Field

The invention relates to the technical field of machinery, in particular to a multifunctional remaining needle.

Background

The existing indwelling needle used in clinic has the following defects: 1. the patient keeps the improper movement or posture change of the limbs at the side of the indwelling needle, so that the extension tube at the infusion end of the indwelling needle is pressed and folded, thereby causing the unsmooth infusion and even causing the blockage of the indwelling needle; 2. the transfusion valve on the indwelling needle extension tube is made of hard material, and the skin of the pressed part is red or even broken when the skin is fragile or the pressed part of the body is punctured or the body position is changed to cause the pressed patient; 3. the tail end of a hose at the end of a common indwelling needle or a positive pressure indwelling needle head and a valve of an extension tube have larger space, when blood pressure is measured or the punctured limb is in strenuous activity or is pressed, the phenomenon of blood backflow frequently occurs, even the blood backflow flows into a transfusion pipeline, the risk of blockage of the indwelling needle is increased, and the tension and the anxiety of a patient are increased; 4. sometimes, a clinical nurse performs venous blood collection from an indwelling needle for convenient operation; 5. when the Y-shaped remaining needle is used for simultaneous transfusion at two ends, the transfusion pressure at the end A is over high due to the over-high transfusion speed at the end A or the over-high input liquid amount in a short time, and when the pressure is higher than the pressure of a transfusion pipeline at the end B, the liquid flows into the end B from the end A, so that the transfusion at the end B flows back and the transfusion can not be smoothly carried out; 6. the existing indwelling needle used clinically has no functions of measuring body temperature, pressure, SPO2 and heart rate. In view of this, we propose a multifunctional indwelling needle.
