Underwater impact injury experiment simulation device

Abstract

The invention relates to an underwater impact injury experiment simulation device. The underwater impact injury experiment simulation device comprises an underwater experiment support, an animal fixing brace and an underwater breathing system, wherein the underwater experiment support comprises an inner fixing ring, an outer fixing ring, 16 spokes and a square beam; the inner fixing ring and the outer fixing ring are used for stabilizing the structure of the underwater experiment support; the 16 spokes are uniformly distributed along the diameter direction of the outer fixing ring and are used for fixing the animal fixing brace; and the square beam is used for hoisting the underwater experiment support. The animal fixing brace is formed by welding steel pipes and fixing pieces; and the steel pipes are hollow and used for conveying compressed air to a mask, and the fixing pieces are used for fixing experimental animals. The underwater breathing system is formed by sequentially connecting a compressed air tank, a breather pipe, a steel pipe and an underwater breathing mask. The underwater impact injury experiment simulation device is simple in structure, reasonable in design, controllable in model, high in safety and suitable for underwater medical scientific research tests such as underwater impact injury.

Description

technical field [0001] The invention belongs to diving medicine, in particular to an underwater shock injury experiment simulation device. Background technique [0002] In modern naval warfare, major changes have taken place in weaponry and combat methods. There are more and more underwater combat personnel, and underwater weapons such as torpedoes, mines, and depth charges are equipped and applied on a large scale. Therefore, the shock waves of underwater explosions cause more and more injuries to personnel in underwater combat positions, which has become a hot spot and difficulty in military medicine in the world. The density of water is 800 times that of air, and it is relatively incompressible. Compared with air shock waves, underwater shock waves have the characteristics of fast propagation speed, long propagation distance, and no typical compression and sparse regions, so it can cause injuries The mechanism and damage characteristics are different from air shock waves...

Problems solved by technology

Chinese patent document CN 101843529 B discloses an underwater breathing system for animals, which is used to ensure that animals breathe normally underwater, but there are also corresponding deficiencies: 1. The device has low stability and anti-knock performance, and the maximum pressure it can withstand is only 5MPa; 2. There are fewer groups of animals, fewer places to deploy, and fewer animals for each experiment

Chinese patent document CN 201620984808.2 discloses an underwater animal test device, which can ensure the normal breathing of animals underwater. However, this patent design requires equipment such as cranes, and is suitable for large-scale operating platforms such as offshore and is difficult to operate, which cannot meet the needs of laboratories.
