Description
Technical field:
This utility model relates to medical apparatus and instruments, is specifically related to brain protection therapeutic equipments.
Background technology:
The inferior cryotherapy (31 ℃～35 ℃) of generally acknowledging is unique effective ways of brain protection at present.Studies confirm that in a large number inferior cryotherapy can obviously alleviate the pathology damage degree of cerebral ischemia, cerebral hemorrhage and craniocerebral trauma both at home and abroad, promote the recovery of function of nervous system, have reliable cerebral protection.Evidence-based medicine EBM proves that the brain-protection drugs of using is all invalid substantially at present.In conventional mild hypothermia therapy technology, because scalp can not effectively contact with the refrigeration position, mainly rely on air and conduct heat, and the heat conductivity of air is very low, approximates 0.026W/ (m.K) greatly, human brain tissue is generally about 0.8W/ (m.K).Studies show that, make head part's temperature be reduced to the mild hypothermia therapy temperature, so must be greater than 0.1W/cm at the refrigeration work consumption of head part position
2If, conduct heat by air and to realize the mild hypothermia therapy temperature, suppose that distance is 2mm between scalp and the chill surface, we can rough estimate refrigeration position will be with the scalp thermograde near 80 ℃, this is to be difficult to realization technically.So the conventional Refrigeration Techniques such as ice cap that adopt the air heat transfer type are difficult to reach the effect of mild hypothermia therapy.The inferior cryotherapy of abroad reporting for work all is to adopt the method for total body hypothermia, the frequent concurrent blood pressure drops of this method, various arrhythmia, serious ion imbalances, breathing and urinary system infection, symptoms such as hypovolemic shock, pneumonia, arrhythmia and disorders of hemostasis appear in the rewarming process easily, the too fast intracranial pressure that also can make of rewarming raises, and expense is very high.
The utility model content:
The purpose of this utility model provides the local inferior hypothermia brain protection of a kind of pasting type simple in structure, that curative effect is high, easy to use.This utility model is by refrigerator 2 and stick medicated cap 1 and form; The described medicated cap 1 that sticks comprises medicated cap body 7 and fixing band 5 two parts, the position that medicated cap body 7 tops contact with scalp has air-vent 3, the position symmetry that medicated cap body 7 middle parts contact with ear has two slotted eyes 6, the left and right sides of medicated cap body 7 bottoms is connected with fixing band 5 respectively, the surface of fixing band 5 is connected with positioner 4, medicated cap body 7 tops also have cylindrical hole 8, and refrigerator 2 is installed in the cylindrical hole 8.The local inferior hypothermia brain protection of pasting type of the present utility model adopts has high thermal conductivity coefficient (greater than 200W/ (m.K)) material as the heat transfer medium between scalp and the refrigerating part; according to the thermal conduction study ultimate principle; it is long-pending that the size of transmission heat is proportional to heat conductivity, area of dissipation and thermograde three; this mode can obtain splendid radiating efficiency in very little heat transfer area and temperature gradient, thereby makes focus partly quick (in the 16min) reach inferior low temperature.Because heat transfer area is little, this Therapeutic Method does not need head or whole body are carried out whole inferior low temperature, only need carry out local inferior low temperature, thereby significantly reduce the complication that whole body sub-low-temperature brought, as electrolyte disturbance, pneumonia and arrhythmia etc. therapentic part.Confirm that through zoopery this therapy can reduce the temperature of intracranial tissues effectively in time window.Checked through PET in 40 minutes behind the inferior low temperature of body local and confirm, head low temperature side and offside are compared, the cerebral tissue glucose metabolic rate of low temperature side has descended 15%～20%, and do not have the multiple complication of total body hypothermia, it has, and side effect is little, expense is low, easy to use, simple in structure, advantage that therapeutic effect is good.
