Background technique
It is known that blood clinically has very important effect as a kind of special drug.In surgical operation,Patient will appear different degrees of acute bleeding, and some patientss needs are transfused a large amount of blood in art to sustain life in the short timeSign is steady.In addition, after capital operation and post-traumatic patient equally will appear difference in intensive care unit even public wardThe acute or chronic anaemia of degree.Infused blood and colloid, crystalloid fluid etc. against time are needed for progressive bleeding patientsDrug comes replenishment of blood content, control bleeding, and mitigates the symptoms such as the increase of the cardiopulmonary load as caused by anaemia.So massive transfusionIt is the rescue scene often occurred in clinical position.
But after the banked blood of the especially a large amount of infusion cryo-conservations of blood transfusion, patient usually will appear hypothermia, blood coagulationA series of complication such as dysfunction, anoxic exacerbation, this can seriously affect rescued effect.Therefore, massive transfusion is needed in rescueWhen patient, can as early as possible by the banked blood rewarming of low temperature to close to body temperature and whether input patient's body for successful rescue veryIt is crucial.
Currently, after the blood from hospital blood bank taking-up cryo-conservation to before being infused into patient's body, medical staffIt needs round-trip blood bank to take blood, and different methods is taken to carry out heating rewarming to blood.In most of hospitals, medical staff to blood bankThe conventional storage case without heating function is used when taking blood.Common heating rewarming measure has: low temperature blood is put in fiber cropsIt is body temperature that blood rewarming, medical staff or family numbers of patients pass through oneself by the heat that machine distributes on liquor-saturated machine is that blood is multipleTemperature, water-bath rewarming, there are also part medical institutions to use expensive blood transfusion apparatus heating apparatus for blood rewarming.But these Thawing MethodsAll there are various drawbacks, firstly, it is not scientific by heat, body temperature, water-bath rewarming that Anesthesia machine distributes, temperature fluctuation is big,Rewarming time is long, effect is poor, cannot avoid pollution, although constant to the temperature for pipe heating method rewarming of transfusing blood, can be to avoid dirtDye, but first rewarming is still needed to before being transfused, and infusion velocity is slower, is only applicable to the slow blood transfusion of chronic blood loss patient, is not suitable forRescue blood transfusion when bleeding profusely.
Therefore, need it is a kind of can science, the free of contamination rewarming apparatus for fast implementing blood rewarming, become and urgently solveCertainly the problem of.
Summary of the invention
In view of the above-mentioned problems in the prior art, the present invention, which provides, a kind of takes blood rewarming with heating and heat-insulating deviceCase carries heating, heat insulation function convenient for storage blood, can solve at present most medical institutions in rescue massive transfusion pairThe problems such as blood rewarming method is not scientific, the time is long, effect is poor can directly improve the final result of rescue.
To realize said effect, of the invention is adopted the following technical scheme that
