Background
Along with the development of medical science and technology, people have a higher and higher degree of attention to clinical hemostasis, and clinical intravenous blood sampling inspection, puncture and transfusion are all required to be subjected to hemostasis treatment, so that wounds with improper hemostasis are likely to become bacterial hotbeds, and wound infection is caused. The common hemostasis method is to use hemostatic tools such as sterilized cotton balls, sterilized cotton sticks, hemostatic patches and the like, but the hemostatic tools such as sterilized cotton balls, sterilized cotton sticks, hemostatic patches and the like are used, the hemostatic can be performed only by the patient continuously pressing the blood sampling, puncturing and transfusion parts for 5-10 min, the movement of the patient is limited, and the hemostatic method has lower convenience for the patient; furthermore, many patients can stop bleeding because the patients do not understand the effective time of pressing after puncturing or some patients are inconvenient to press together with themselves, so that the pressing time is short or blood vessels continue to bleed, and even local tissue congestion, bluish, purple and swollen conditions occur due to local bleeding of blood sampling points, so that a certain negative influence is caused to the body and mind of the patients.
Aiming at the situation, a new hemostatic form, namely a hemostatic patch, is presented, the utility model with publication number CN203970474U discloses a double-wing elastic automatic pressing hemostatic patch, which comprises a hemostatic patch body and adhesive tapes stuck on two ends of the hemostatic patch body, wherein the hemostatic patch body is in an inverted shape, a disinfection hemostatic cushion is arranged in the middle of the hemostatic patch body, and the disinfection hemostatic cushion is stuck on the hemostatic patch body through a non-woven sterile adhesive tape. When in use, the disinfection hemostatic cushion is aligned to the needle eye, the release paper attached to the hemostatic patch body is torn off, the adhesive patch is stuck on the skin, the hemostatic patch can be automatically stopped without being pressed by a patient by hands, and the hemostatic patch can be torn off after being stuck for 5-10 minutes, so that the hemostatic patch is convenient to use, and has no side effects of blood stasis, pain, swelling and the like.
However, the hemostatic patch has the following disadvantages: the adhesive tape of the hemostatic patch has no good stretchability, and the situation that the hemostatic patch cannot stop bleeding due to insufficient pressure on a wound can occur; in addition, the hemostatic patch is not suitable for people with skin allergy caused by adhesive patches.
