Medical injector with convex lens color scales

Abstract

The invention discloses a medical injector with convex lens color scales. The medical injector comprises a pushing rod, a liquid storage barrel, a needle head frame, a needle head protective sleeve, amagnifying lens, a pushing soft body and a needle head. The pushing rod is installed in the liquid storage barrel. The conical pushing soft body is installed at the front end of the pushing rod. Theouter edge of the pushing soft body and the inner wall of the liquid storage barrel are sealed. A liquid outlet - is formed in the front end of the liquid storage barrel. The liquid outlet - is connected with the needle head through the needle head frame. The needle head protective sleeve is mounted outside the needle head frame. Color scales are arranged on the outer wall of the liquid storage barrel from the position close to the liquid outlet - to one side of the pushing rod. Numbers are arranged on one sides of the scales. The magnifying lens is arranged above the scales and the number area, and the magnifying lens is fixedly connected with the outer wall of the liquid storage barrel. For older medical workers or self-rational patients, the medical injector can be used to reduce medical accidents caused by poor eyesight of the medical workers, and the accuracy is improved. Doctors and nurses or attendants can conveniently communicate and describe the injection amount and memorize the injection amount.

Description

technical field [0001] The invention relates to the field of medical equipment, and specifically discloses a medical injector with a convex lens and a color scale.
