Novel scalp venous indwelling needle for pediatric nerve nursing

Abstract

The invention provides a novel scalp venous indwelling needle for pediatric nerve nursing. The needle comprises a needle body, wherein adhesive tapes are fixedly connected to the sides, away from theneedle body, of a fixing seat and an elastic seat, a rotating shaft is rotatably mounted in the fixing seat, a pressing plate is fixedly connected to the side, away from the needle body, of a pinion,the rotating shaft is connected with a sliding block through a pull rope, a rotating disc is rotatably mounted in the elastic seat and located on the front face of the sliding block, and a shifting rod inserted into the rotating disc is fixedly connected to the bottom of a detection rod. The elastic seat deforms along with wrinkles and flattening of scalp, the detection rod drives the shifting rodto move up and down, and the shifting rod drives the rotating disc to rotate through an inserting block and a wave groove, so that a magnetic block and a magnetic sheet are staggered after being aligned; and the sliding block is pushed to move under the action of isotropic repulsive force and a spring, the sliding block pulls the rotating shaft to rotate through the pull rope to drive the pressing plate to deflect back and forth, the adhesive tapes are flattened again, and the problem that the indwelling needle is unstable due to the fact that adhesion between the adhesive tapes and the scalpbecomes loose after the adhesive tapes are rolled up is avoided.

Description

technical field [0001] The invention relates to the technical field of venous indwelling needles, in particular to a novel scalp venous indwelling needle for pediatric nerve care. Background technique [0002] Nervous system diseases refer to diseases caused by infection, vascular disease, tumor, trauma, severe immune disorders, genetic degeneration, congenital abnormalities, nutritional deficiencies and metabolic disorders of the nervous system and bone marrow muscles. Scalp veins can be used in neurological care. The method of infusion, scalp vein indwelling needle is a commonly used infusion tool, which can reduce the pain and blood vessel damage of patients, and keep the venous path unobstructed. [0003] In the existing technology, the scalp vein indwelling needle is generally fixed on the patient's head by medical tape, but the adhesiveness of the medical tape is not particularly strong, and when the patient accidentally knocks down the tape, or the patient's scalp is ...

AI Technical Summary

Problems solved by technology

[0003] In the existing technology, the scalp vein indwelling needle is generally fixed on the patient's head by medical tape, but the adhesiveness of the medical tape is not particularly strong, and when the patient accidentally knocks down the tape, or the patient's scalp is deformed due to scratching the head , it is prone to tape curling. After the tape is curled, the rolled-up situation will become larger and larger, resulting in instability of the indwelling needle. Especially for pediatric patients, children are more lively and active, and the above problems are more likely to occur
