Newborn indwelling needle based on intelligent detection of infusion pressure

Abstract

The invention discloses a newborn indwelling needle based on intelligent detection of infusion pressure, which is characterized in that the neonatal indwelling needle comprises a positive pressure joint (1), an extension pipe (3) connected under the positive pressure joint (1), the other end of the extension pipe (3) is connected with a transparent three-way valve (8), an outlet connecting conduit(9) of the transparent three-way valve (8), and a steel needle (10) is arranged inside the conduit (9). The other outlet of the three-way valve (8) is connected with a barrier block (6), and a steelneedle (10) is connected to the needle holder (5) through the barrier block (6). The side of the positive pressure joint (1) is connected with an infusion pressure intelligent detection device (2). The infusion pressure intelligent detection device (2) comprises a miniature pressure detection probe (21) and a pressure detection circuit (22). A pressure setting module (22a) and a pressure comparison module (22b) are arranged on the pressure detection circuit (22). The pressure detection circuit (2) is electrically connected to the alarm device (11). The invention can alarm in time when the indwelling needle catheter is displaced by sensing the infusion pressure. The invention has simple structure and convenient use, and is suitable for popularization and use.

Description

technical field [0001] The invention relates to the medical field of newborns, and more specifically relates to an indwelling needle for newborns based on intelligent detection of infusion pressure. Background technique [0002] The use of indwelling needles can reduce the pain and fear of injections caused by repeated venipuncture in children, relieve the anxiety of parents, facilitate clinical medication, rescue medication for acute and critical patients, reduce the workload of nurses, and reduce the risk of children's anxiety. Pain, so intravenous indwelling needles are widely used clinically. Facing the special group of children, the indwelling time of intravenous indwelling needles and the comfort of children have become the most concerned issues for nurses and parents, and they are also the symbol and promotion of the successful use of indwelling needles. premise. [0003] However, there is a problem that when the indwelling needle is used, the catheter will shift due...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above problems, the present invention proposes a neonatal indwelling needle based on intelligent detection of infusion pressure, which solves the problem that the traditional indwelling needle cannot be discovered by nurses in time when the catheter is moved out of the blood vessel of the newborn, which affects the health of the newborn.
