The utility model relates to a hemostasis by compression trousers after full brain angiography of femoral artery intubate, especially a hemostasis by compression trousers in sand bag location after full brain angiography of femoral artery intubate.
Background
According to the Chinese stroke prevention and treatment report 2017, stroke is the first cause of death (life reduction) of residents in China and the first killer of life health. The incidence of stroke in our country is higher than the global level and increases at a rate of 8.7% per year. While DSA (transfemoral full-brain angiography) is a common examination means for cerebrovascular disease diagnosis. At present, after a patient is clinically subjected to full-cerebral angiography through femoral artery intubation in a hospital, the condition change and the wound condition need to be closely observed, and because the postoperative intubation part of the patient is easy to have the conditions of blood seepage, hematoma, large ecchymosis and the like, a sand bag (with the weight of about 1Kg) needs to be used conventionally to press the intubation part for 6 hours in the nursing process, so that the bleeding risk of the intubation part is reduced, and the healing of the intubation part is accelerated. As the traditional patient trousers are worn by the clinical patient, the traditional patient trousers cannot fix the sandbag, the sandbag is easy to shift, nursing staff and family members of the patient are required to continuously correct the position of the sandbag, and fatigue nursing is caused for a long time; the patient needs the braking of the operative limb after the operation and is strictly bedridden for 24 hours, the movement is relatively limited, the patient feels untimely and can move the body without self-inhibition, and the phenomena of pressing the sandbag to shift and slide are generated occasionally; when a patient who is not awake, unconscious and restless is anesthetized, and the nursing personnel and the family members of the patient do not pay attention to the movement and the sliding of the sand bag, the bleeding risk of the intubation part can be increased, the healing of the intubation part is influenced, and the nursing effect of the intubation part is reduced; the defecation and the urination of the bedridden patient need to be carried out on the bed, and the patient is very inconvenient to wear and take off the patient trousers, wastes time and labor and is inconvenient to nurse; and the bleeding condition of the wound after the operation is inconvenient to observe; in view of the above reasons, a sand bag positioning compression hemostasis trousers after full cerebral angiography through femoral artery intubation is proposed.
