Description
Technical Field
The invention relates to medical auxiliary equipment, in particular to a human body amputated limb protection box based on a non-contact sensing control perfusion technology.
Background
2412 ten thousands of people with physical disabilities in the population with disabilities account for 29.07 percent, and the people with physical disabilities live at the first place among various disabled people. The factors responsible for limb disability are currently mainly: major factors of limb disability caused by industrial accidents, traffic accidents, disaster accidents, terrorist attacks, diseases, wars and the like. The disabilities, including the physical disabilities, directly bring inconvenience influence on work, study and life in the future to patients, simultaneously greatly limit or even lose labor capacity, bring various mental and psychological influences, seriously reduce the life quality of the patients and families, and increase the load bearing burden to the families and the society.
The other limb is diseased, the most notable of which is the diabetic foot. Taking the Shanghai city investigated in 2008 as an example, the diabetes in the Shanghai city accounts for about 8.6% of the diabetes patients in this year, but only 1.01% in 1980, and the incidence of diabetes is increased eight times in 20 years, and meanwhile, the incidence of diabetes is increased nationwide. In the rescue and treatment of ischemic diseases of lower limbs, physicians gradually found that the main factors causing injury to tissues, not only ischemia itself, but also after restoration of blood supply, excessive metabolite radicals attack cells in the tissues to which blood supply is restored, and the injury is called tissue ischemia-reperfusion injury.
The damage of ischemia is caused by cell necrosis or temporary function damage caused by hypoxia and nutrient deficiency, and the complete blood vessel block may be caused by conduction block and lower wall infarction. The ischemia reperfusion injury is caused by oxygen in blood HbO2 reacting with the dissolved substance of damaged myocardial cells or necrotic myocardial cells to form oxygen free radicals which have an injury effect on partial tissues. The existing protective boxes adopt low temperature to prevent organs from being scrapped, and lack a protective box which can protect the amputated limb, maintain the activity of the amputated limb and replace residual wastes in the amputated limb.
