The invention relates to a hypodermic injection instrument, and belongs to the technical field of medical treatment. The hypodermic injection instrument comprises a needle cylinder fixing cylinder, a sleeve and an injection device, the injection device and the sleeve are respectively arranged above and below the needle cylinder fixing cylinder, the needle cylinder fixing cylinder is half-moon-shaped, a fixing belt is arranged on the periphery of the crescent end of the needle cylinder fixing cylinder, and the sleeve is semi-arc-shaped; the injection device comprises a fixed column side wall and a movable plate which are slidably mounted, a rotating shaft is arranged in the fixed column, the input end of the rotating shaft is connected with the output end of a motor, the motor is arranged in a needle cylinder fixing cylinder, and a gear is mounted in the movable plate and matched with the rotating shaft to drive the movable plate to move up and down, an injector is arranged between the movable plate and the needle cylinder fixing cylinder, and an injector push rod is arranged in the movable plate; and a control system is arranged in the movable plate and used for controlling the moving speed and distance of the movable plate. The hypodermic injection instrument is reasonable in structural design, movement of the injection needle is effectively prevented, discomfort of a patient is reduced, the injection speed is adjusted and controlled, operation is more standardized, and practicability is high.
Description
technical field [0001] The invention belongs to the field of medical technology, in particular to a hypodermic injection instrument. Background technique [0002] In the clinical work, the subcutaneous injection nursing operation is basically performed every day. During the operation, the lower edge of the deltoid muscle of the patient's upper arm and the umbilical circumference of the abdomen are selected. Subcutaneous injection technique: tighten the local skin with the left hand, lift the skin if the person is too thin, hold the syringe in a flat grip with the right hand, fix the needle plug with the index finger, with the slope of the needle tip facing upward, and quickly penetrate the skin at an angle of 30-40° to the skin, and the needle is about 1cm deep . The existing manual operation by the operating nurse has a certain degree of depth, difference and non-standardization of the angle, and the back and forth movement after the needle is inserted, and the fast and sl...
