Abstract

The invention relates to an animal underwater impact injury protection device. The underwater impact injury protection device comprises an outer protection layer, a porous material layer, a bridle layer and a buffer layer. The outer protective layer is cylindrical, the wall thickness is 0.3 cm, and the outer protective layer comprises an outer protective layer body, a handle and an upper cover which are all made of ultra-high molecular weight polyethylene materials and used for containing animals. The porous material layer is made of foamed aluminum, has the thickness of 2cm and is used for absorbing shock waves; the bridle layer is made of polyurethane fibers, the thickness of the bridle layer is 0.2 cm, excessive expansion of the chest and abdomen can be limited, and the over-traction effect of the body is avoided. The buffer layer is made of soft polyurethane foam plastic, the thickness of the buffer layer is 3 cm, and the high-acceleration displacement strength of animals under the action of shock waves can be reduced; the outer protective layer, the porous material layer, the bridle layer and the buffer layer are sequentially arranged from outside to inside and are fixed through glue and rivets. The animal underwater impact injury protection device is simple in structure, reasonable in design, light and easy to carry, and suitable for underwater medical scientific research tests such as underwater impact injury and the like.

Description

technical field

[0001] The invention belongs to diving medicine, and in particular relates to an animal underwater impact injury protection 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, underwater explosion shock waves cause more and more damage to underwater battle 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 zone and sparse zone, so it can cause injury The mechanism and damage characteristics are different from air shock waves. The study fo...

Embodiment

[0015] Examples of the present invention are Figure 1 to Figure 2 As shown, the present invention comprises an outer protective layer 1 , a porous material layer 2 , a belt layer 3 and a cushioning layer 4 . The outer protective layer 1 includes an outer protective layer main body 5, a handle 6, and an upper cover 7, and the outer protective layer main body 5 and the handle 6 are fixed and formed by co-extrusion. The outer protective layer 1, the porous material layer 2, the belt layer 3 and the buffer layer 4 are arranged sequentially from outside to inside, and the four are bonded by KD-833 special superglue, and the upper and lower parts of the outer protective layer main body 5 are passed through rivets 8 fixed.

[0016] In this embodiment, the main body 5 of the outer protective layer is cylindrical, with a wall thickness of 0.3 cm, a bottom surface diameter of 15 cm, and a height of 50 cm, forming a protective device shell. The cylindrical structure can decompose the f...
