Description
Technical Field
The invention relates to the technical field of medical auxiliary instruments, in particular to an intramuscular injection positioning device for a trauma patient.
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, also known as intramuscular injection, is widely used and can be used to push various irritative drugs, and the muscle vessels are particularly abundant and the drugs can be quickly absorbed by injection.
Clinically, medical staff need to carry out intramuscular injection on the buttocks due to the fact that the buttocks of a patient are wounded, the most common injection part for carrying out intramuscular injection on the buttocks is gluteus maximus, and the injection positioning of the gluteus maximus is generally characterized by a cross method and a connecting line. The cross method is to draw a horizontal line from the apex of the cleft hip to the left or right, draw a perpendicular bisector from the apex of the iliac crest downward, and divide the hip into four quadrants, wherein the upper and outer quadrants avoid the inner angle and are the injection regions. The injector is required to be experienced, skilled in technology and concentrated in energy to accurately find and locate. However, when intramuscular injection is performed to the wound of the hip of a patient, since the medical staff at first school is not skilled in the method and recognizes the deviation of the body surface marker, it is not easy to find the injection area, and when the injection is performed, since the medical staff performs intramuscular injection for a long time or for a large number of times, the hand of the hand is easily shaken when the hand is kept in one posture and position for a long time.
