Abstract

The invention discloses an anti-blocking venous child indwelling needle, and relates to the technical field of indwelling needles, in particular to a needle sleeve and a friction plate, a needle head is arranged in the needle sleeve, a transparent three-way shell is installed at the left end of the needle head, a transparent three-way joint is partially and fixedly arranged in the transparent three-way shell, and a limiting sliding way is arranged outside the transparent three-way joint; and a connecting sleeve plate is rotationally installed outside the limiting sliding way, a connecting holding handle is connected to the upper end of the connecting sleeve plate, and the friction plate is located on the outer surface of the connecting holding handle. According to the anti-blocking venous child indwelling needle, through the design that the threaded cover is arranged in the heparin cap, when the heparin cap is connected with the positive pressure connector, threaded installation can be conducted from the exterior of the positive pressure connector through the design of the heparin cap, and meanwhile threaded installation can be conducted again from the interior of the positive pressure connector through the built-in threaded cover in the heparin cap; the possibility that bacteria enter the positive pressure connector is effectively reduced, the structure is simple, and a user can conveniently and rapidly install the positive pressure connector.

Description

technical field [0001] The invention relates to the technical field of indwelling needles, in particular to children's indwelling needles for preventing vein blockage. 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. [0003] During the use of the existing indwelling needles, it is inconvenient for doctors to store the heparin cap according to the needs of use, and it is inconvenient to rotate the connecting handle at an appropriate angle according to the puncture usage habits. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the present invention provides an anti-clogging intravenous indwell...
