Animal Crushing Injury-Crush Syndrome Experimental Apparatus

Abstract

The invention relates to an experimental device for animal CI-CS (crush injury-crush syndrome). The experimental device comprises a base, wherein a fixing device and a crushing device are arranged on the base; the crushing device comprises a fixed roller and a movable roller which are horizontally arranged and capable of rolling in opposite directions; multiple groups of concave crushing structures are arranged on a crushing surface of the movable roller, multiple convex crushing structures are arranged on a crushing surface of the fixed roller, and the multiple concave crushing structures and the multiple convex crushing structures are matched with one another; rotating shafts are arranged at two ends of the fixed roller, and the fixed roller is arranged on the side wall of the base in a crossing manner; the movable roller is arranged in a guide rail groove in the side wall of the base in a crossing manner through a concentric shaft, the concentric shaft can slide in the guide rail groove, a clamping lock is arranged on the concentric shaft, and the concentric shaft and the clamping lock can control the movable roller to slide and get locked relative to the fixed roller. The experimental device for animal CI-CS simulates the injury caused by the fact that four limbs are crushed by the rollers in production practice, and a model is more practical; the experimental device is simple in overall structure, convenient to operate, high in measurement precision and good in experimental repeatability, and reliable experimental data can be obtained.

Description

technical field [0001] The patent of the present invention relates to crush injury-crushing syndrome animal experimental medical experimental equipment, in particular to an animal crush-crushing syndrome experimental device. Background technique [0002] Crush injury (crush injury) refers to the soft tissue injury mainly caused by the limbs or trunk being squeezed for a long time, and iatrogenic reasons such as excessive tourniquet binding time. These injuries often lead to ischemic necrosis of muscle tissue in the body, and the release of muscle cell components into the blood presents systemic pathophysiological changes characterized by myoglobinuria, hyperkalemia, hyperphosphatemia, acidosis, and azotemia. A group of clinical syndromes that eventually lead to acute renal failure are called crush syndrome (Crushsyndrome). It is more common in damages caused by major natural disasters and traffic accidents such as wartime, earthquakes and mudslides. In earthquakes, the inc...
