Description

Technical Field

[0001] The invention relates to a hemostatic device, in particular to an emergency hemostatic device and a use method thereof. Background Art

[0002] At present, patients need to stop bleeding after trauma. Usually, hemostatic clamps are used to close the wound. In emergency treatment, they can replace sutures to achieve the purpose of rapid hemostasis. They are used to stop bleeding at the junction of limbs and body. At present, the most commonly used one is the iTClamp hemostatic clamp commercialized in the United States, but it has the following disadvantages:

[0003] (1) The main body of the iTClamp hemostatic clip is much larger than the eight nails, and there is a possibility that the device will fall off during the transportation of the patient due to insufficient grip;

[0004] (2) The iTClamp hemostatic clip is relatively large. After clamping the wound, it will remain on the body surface, which will hinder the use of dressings to apply pressure to the wound and will no longer be able to perform compression hemostasis. Summary of the invention

[0005] The technical problem to be solved by the present invention is that the existing hemostatic clip has the problem of falling off, and it also hinders compression hemostasis when used. The present invention provides an emergency hemostatic device, which can replace the principle of quickly closing the wound with needle and thread suture to achieve hemostasis. The push rod pushes out the puncture needle and matches it with the connector, and the wound is quickly stapled to close the wound to achieve the hemostatic effect. It only needs to press the wound, and the operation can be completed within a few seconds. There is no problem of falling off, which does not affect the distal perfusion, nor hinder the compression hemostasis and further bandaging without suture. The connector can be detached from the main body of the hemostatic device, and finally only the puncture needle and the connector are retained on the wound;

[0006] The puncture needle used to staple the wound can be tightened in one direction to ensure sufficient pressure to stop bleeding;

[0007] The pain is mild and no anesthesia is required. It is just the pain of several needles quickly piercing the skin.
