Technical Field
The invention belongs to the technical field of medical instruments, and particularly relates to a peritoneal stimulation abdominal muscle contraction detection device and a peritoneal stimulation abdominal muscle contraction detection method.
Background
Peritonitis is one of common clinical emergency, inflammation, tumor, hemorrhage and the like can cause peritonitis, and if a correct treatment mode is not adopted in time, serious danger is brought by the illness state; the abdominal wall of human body is a multi-layer structure, the deepest layer is composed of the peritoneum and the abdominal muscles, and is most sensitive to the inflammatory stimulus response of the abdominal cavity. When inflammation occurs in the abdominal viscera of a patient, the local abdominal wall is pressed, the peritoneum is stimulated to produce pain, called tenderness, and the abdominal muscles can rapidly undergo reflex contraction. When the physician continues to press the abdominal wall with his hand for 2-3 seconds, the sudden release stimulates the peritoneum again, which is called rebound pain, and the abdominal muscles contract again rapidly in reflexion. Because the nerve reflex of tenderness and rebound pain belongs to low-grade reflex, the reflex arc is short, the occurrence is rapid and is not controlled by the central nervous system of the brain, so the occurrence is rapid and the duration is short. At present, special equipment for measuring peritoneal stimulation is lacking clinically, a traditional palpation method is adopted, namely, a doctor directly performs abdominal examination on a patient by hand, the degree of abdominal muscle tension and whether muscle reflex contraction exists are completely judged by means of personal hand feeling and experience, when the doctor encounters the condition that the patient cannot cooperate, such as shock, crying of children, intentional sickness and the like, whether tenderness and rebound pain exist cannot be accurately judged, and misdiagnosis or missed diagnosis risks are easy to occur.
