Description

hemostatic device

technical field

The utility model relates to a hemostatic device, in particular to a hemostatic device capable of movably adjusting the pressurized position of the hemostatic device by improving the finger-pressing member so as to alleviate the patient's discomfort and maintain the function of the hemostatic device. the

Background technique

When the body has a wound or undergoes an operation, it will bleed. The method used to reduce blood loss is called hemostasis. Commonly used hemostasis methods are: tourniquet hemostasis, affected part elevation hemostasis and direct pressure hemostasis. The easiest way to stop bleeding is to cover the wound with gauze and pressurize the wound to stop the bleeding. According to the size of the blood vessel, use "four fingers" or "palm" to pressurize and cooperate with raising the wound The limbs, so that the injured part is higher than the heart to achieve the effect of hemostasis. the

The tourniquet hemostasis method is mainly used for larger arterial vessel ruptures, and is only used when other hemostasis methods are ineffective. When using a tourniquet, it should be tied above the bleeding wound of the extremities (mainly to stop the bleeding), raise the affected limb for a few minutes in advance, and place a towel or other soft tissue on the local area to prevent tissue abrasion. After using a tourniquet, the blood supply to the tissue below the ligation site is interrupted, which can easily lead to tissue ischemia and necrosis after a long time, so the time for tying the tourniquet should not be too long, and it should be relaxed every 30 minutes, about half a minute to one minute each time to allow blood to circulate. For this reason, there should be a clear mark on the place where the tourniquet is used, indicating the time when the tourniquet is tied, so as to facilitate the transfer. The receiving unit can refer to this mark to loosen the tourniquet and make necessary treatment. the

However, when the artery ruptures, the traditional tourniquet cannot be fixed and worn to stop the bleeding, and it is still necessary to pressurize the sandbag to stop the bleeding. The medical staff presses the sandbag on the wound and directly pressurizes it for 8 hours. Lying flat for 6-8 hours, because the limbs under pressure cannot be bent at will, the patient can hardly move, which is very inconvenient and uncomfortable, and the environment is troubled by the disposal of waste polluted sand bags. the
