Description

Anti-hand-shake injection device and working method thereof

Technical Field

The invention relates to a hand-trembling prevention injection device and a working method thereof, and belongs to the field of medical instruments.

Background

Injection, which refers to the injection of liquid or gas into the human body by means of medical devices such as syringes, to achieve the purpose of diagnosis, treatment, and prevention of diseases. Unlike taking medicine, the medicine can reach blood quickly and act after being injected. Intramuscular injection is also called intramuscular injection, is widely used, and can be used for pushing various irritative drugs (such as penicillin, sulfanilamide, vitamins, enzyme preparations, alkaloid preparations, blood, tetanus antitoxin and the like). The muscle and blood vessels are particularly rich, the medicine can be quickly absorbed after being injected, and the general dosage is 5-10 ml. The injection site is usually composed of deltoid muscle, gluteus maximus, gluteus medius, gluteus minimus, and vastus lateralis. The needle is inserted into the body for 2.5-3 cm. The gluteus maximus is used most, the cross method, a horizontal line is drawn from the apex of the gluteal fissure to the left or right side, then a vertical bisector is drawn from the apex of the iliac crest, and an injection site is formed in the upper outer quadrant avoiding the inner corner. The joint line method is to take the joint line of the anterior superior iliac spine and the superior coccyx 1/3 as the injection site. If the muscle is relaxed, the needle insertion and withdrawal are rapid, and the drug pushing is slow, the general intramuscular injection of the drug has no pain. If the injection part is far away from nerves and blood vessels, and blood return does not occur in the back-pumping before the medicine is pushed, the intramuscular injection is safer.

Since the hand of a person cannot hold a fixed position for a long time while performing an injection, shaking of the hand is not consciously controlled while holding a posture and position, and particularly shaking is noticeable when the hand of a person is holding a small-sized article. Furthermore, medical personnel usually perform a standing operation during injection to facilitate the injection, and cannot move during the injection, which may cause the needle to move and cause pain to the patient.
