CN201871049U - Luminous needle - Google Patents

Abstract

The utility model discloses a luminous needle, comprising a needle body; a groove is arranged in the needle body, a copper electrode and a zinc electrode which are used as a positive electrode and a negative electrode are respectively suspended in the groove, electrolyte solution is filled in the groove, the liquid level of the electrolyte solution exceeds the bottom ends of the positive electrode and the negative electrode, and a lamp tube is externally connected with the bottom ends of the positive electrode and the negative electrode. When the needle is inserted, a needle point and the skin form an included angle within 15-30 degrees, and light can be emitted, so as to prompt people that the needle can be inserted by the angle, so that the venipuncture effect can be effectively improved.

Description

Irradiative pin

Technical field

This utility model relates to the pin that venipuncture is used.

Background technology

During venipuncture, inserting needle when requiring to be 15-30 ° between needle point and the skin is if correctly hold this best angle, for abecedarian or the not abundant people of experience, be difficult to accomplish,, will finely address this problem if design a kind of device that can quantitatively determine this angle.

The utility model content,

The purpose of this utility model provides a kind of irradiative pin, is 15-30 ° between needle point and the skin when inserting needle, can send light, and prompting people this angle can inserting needle, has improved the effect of venipuncture effectively.

The technical solution of the utility model is as follows:

Irradiative pin includes needle body, is provided with groove in the described needle body, suspend respectively in the groove and be provided with copper electrode, zinc electrode as positive and negative electrode, electrolyte solution is housed in the groove, and the liquid level of electrolyte solution surpasses the bottom of positive and negative electrode, and the bottom of positive and negative electrode is externally connected with fluorescent tube.

Described groove floor has 15-30 ° domatic.

This utility model content is utilized the principle of battery charge, and fluorescent tube is powered, and makes lamp luminescence to be 15-30 ° between needle point and the skin when inserting needle, can send light, and prompting people this angle can inserting needle, has improved the effect of venipuncture effectively.
