Description

Technical Field

[0001] The invention relates to the technical field of emergency medicine, and in particular to a hemostatic device. Background Art

[0002] Soldiers are injured and sacrificed on the battlefield mainly due to excessive blood loss, especially penetrating wounds and blind wounds caused by bullets or shrapnel, which are more serious, causing 60% of soldiers to die due to their massive bleeding; studies have shown that rapid hemostasis and rescue within 10 minutes of injury is a key factor in determining their survival. Currently, the most commonly used methods for treating penetrating wounds and blind wounds are compression hemostasis, burning hemostasis, and the use of grease and gauze to fill and stop bleeding. However, due to the limitations of wartime conditions and treatment effects, the above-mentioned hemostasis methods have low hemostasis efficiency and long hemostasis time, which are far from meeting the treatment requirements for penetrating wounds and blind wounds. Therefore, it is very necessary to develop a hemostasis device that can quickly stop bleeding from penetrating wounds and blind wounds on the battlefield. Summary of the invention

[0009] Preferably, one end of the conveyor away from the open end of the conveyor is in the shape of a hollow semi-spherical ball, and the tray is in the shape of a hollow semi-spherical ball.

[0010] Preferably, it also includes an operating handle, one end of which is fixedly connected to a surface of the baffle away from the conveyor.

[0011] Preferably, the axis of the support rod and the axis of the operating handle coincide with the axis of the conveyor.

[0012] Preferably, a weakened portion is provided on the portion of the operating handle connected to the baffle body, and the operating handle is easily broken at the weakened portion and separated from the baffle.

[0013] Preferably, the weakened portion is an annular groove.

[0018] Furthermore, the granular chitosan hemostatic drug not only has the function of rapid hemostasis, but also has high antibacterial properties to prevent wound infection.

[0019] Furthermore, the setting of the support rod and the tray can support the conveyor, making it easier to enter the wound. At the same time, when the wounded is undergoing formal treatment on the wound, the baffle can drive the support rod and the tray to pull the hemostatic drug out of the wound, making it easier to clean the wound.
