Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rehabilitation equipment, in particular to an electronic pressurizing device for forearm hematoma with a limited beam. Background Art
[0002] Forearm hematoma is mostly caused by repeated puncture or rough and improper puncture technique, which causes tearing and damage of the radial artery. Postoperative forearm hematoma is mainly related to ineffective, irregular or premature decompression of postoperative pressure bandage. In this case, standardized operation during surgery and effective bandage hemostasis after surgery are the key to preventing forearm hematoma. If the forearm hematoma is more serious, blood extravasation into the osteofascial compartment will lead to forearm osteofascial compartment syndrome, which is clinically manifested as progressive pain, which can further cause gangrene, shock, renal failure, etc. In severe cases, amputation may even be required. In terms of treatment, under the premise of compression hemostasis and forearm immobilization, the limb is placed at the same level as the heart, and close attention is paid to the blood circulation and sensory movement of the extremities. Once ischemic symptoms such as hand pallor and pain appear, the fascial compartment should be opened immediately for decompression.
[0003] The treatment of forearm hematoma adopts compression hemostasis, and most centers use local compression hemostasis. The most obvious place of forearm hematoma often indicates the site of vascular injury, and a pressure device can be used to directly compress the bleeding point. However, sometimes bleeding will spread to the surrounding along the tissue gap. Therefore, when a hematoma occurs in the forearm, it is recommended to use an elastic bandage to wrap the entire forearm and apply moderate pressure. The pressure of the elastic bandage should be maintained at a level where the radial artery of the affected limb can be touched, and at the same time, pay attention to whether the patient has ischemic symptoms such as pain, numbness, and abnormal movement. Once it occurs, the bandage should be loosened immediately to reduce the pressure.
[0004] However, the existing compression hemostasis equipment cannot compress the tissue gaps of the bleeding point to the surrounding areas when in use, is not convenient for gently controlling the pressure, and cannot detect the pressure. Utility Model Content
