Description

Special syringe of folded form chain hemostasis device

Technical Field

The invention relates to a special syringe for a folding chain type hemostasis device, which is applied to special occasions such as battlefield first aid and the like and belongs to the technical field of medical equipment.

Background

In battlefield first aid, hemostasis is a crucial link, and according to related data, more than 90% of death cases caused by incapability of controlling a large amount of blood loss after injury account for recoverable death cases, particularly after gunshot injury, hemostasis must be timely effective, otherwise, death due to blood loss is easy to occur. The existing hemostatic medical apparatus mainly comprises gauze and a tourniquet, when the gauze is used for hemostasis, the gauze needs to be plugged into a wound which emits blood, but the wound formed by a bullet is very deep, and the hemostasis cannot be realized by using a gauze plugging method; although hemostasis can be completed quickly by using the tourniquet, after the tourniquet is used, for a wounded person, ischemic injury is easy to occur to a far-end tissue, tissue necrosis is caused, risks such as anaerobic infection and the like can cause amputation and even endanger life. Therefore, gauze and tourniquets are not the most rapid, effective and safe means of hemostasis for the injured person who has been gunshot in the battlefield.

The hemorrhage that the rifle wounded caused mainly appears in human inside, and the hemorrhage position blood pressure is high, the blood volume is many, and the hemorrhage that the rifle wounded caused can't be effectively blocked up fast to current medical instrument. In order to save lives, adopt neotype chain hemostasis device to stanch and can reach the stagnant water effect of ideal, chain hemostasis device is made by the hemostatic material of establishing ties, can hinder the wound through the rifle and get into the human direct position of bleeding, directly to bleeding position release hemostatic material, hemostatic material runs into the blood inflation after oppression shutoff and stops up bleeding, on the other hand, chain hemostasis device also conveniently takes out and clears up when follow-up wound treatment. However, because the rifle hinders the wound deeply and the surface of a wound is irregular, it is inconvenient to operate will appear in the use of chain hemostasis device, front end hemostatic material is meeting the blood rapid swelling back, block up the wound surface, make hemostatic material can not reach the inside position of bleeding of wound directly, it is incomplete to stanch, hemostatic effect scheduling problem not good, consequently, need urgently one kind can with the syringe that chain hemostasis device phase-match and convenient operation easily carried, can be fast accurate carry the chain hemostasis device to the position of bleeding, reach the hemostatic effect of ideal, make things convenient for medical personnel to carry and store simultaneously.
