Abstract

The utility model relates to a medical electronic ice cap, which decreases the body temperature of head sections of patients. The medical electronic ice cap is composed of a casing, a semiconductor refrigerator, a temperature controller, a water tank, a circulating water pump, a circulating pipe and a low temperature water jacket. The cold end of the semiconductor refrigerator contacts with the wall of the water tank tightly and carries through favorable heat exchange; the low temperature water jacket is a hemispherical double walled water jacket which is made of a soft heat conducting material; the medical electronic ice cap can be worn on the head section of the patient, and is communicated with the water tank and the circulating water pump by the soft circulating pipe to form a water cycle loop. The utility model has light and handy structure, no noise, and constant temperature, and is widely used as the medical ice cap which decreases the body temperature of head sections of the patients.

Description

Medical electronic ice-cap

This utility model relates to a kind of local medical ice cap that reduces patient head body temperature that is used for.

Ice cap is the medical apparatus that extensively adopts clinically, is usually used in making the patient who has a high fever or cerebrovascular is excessive and the cerebral trauma patient reduces body temperature or local cooling, with protection patient's cerebral tissue, reduce the generation of complication.It is the goods of various easy ice that the ice cap that extensively adopts is gone up in present medical treatment, the poly-bag of for example interior dress rubble ice.Though the ice cap of this structure also can be realized the local body temperature that reduces, it holds time shorter, does not usually reach satisfied effect clinically.Except this class is iced the goods ice cap easily, also adopt a kind of mechanical refrigeration ice cap clinically, its structure is identical with general household electric refrigerator with operation principle, mainly constitute by mechanical refrigerator and the low temperature headgear that can be worn on patient head, the working media of refrigerator is fluorine Lyons, be connected in the low temperature headgear with sebific duct, by the evaporation realization local cooling in fluorine Lyons.This mechanical refrigeration ice cap volume is bigger, heavy, uses inconvenient; Its compressor has mechanicalness noise, and can not long time continuous working.In addition, the leakage in fluorine Lyons also may cause the pollution of environment.

The purpose of this utility model is a kind of advantages of compact and light structure of design, easy to use, noiselessness and can keeps homothermic medical ice cap.

To achieve these goals, this utility model adopts the semiconductor cooler refrigeration, with water as working media and utilize water tank, water circulating pump, circulating water pipe and water at low temperature cover to be linked to be water-flow circuit, thereby constitute a kind of medical electric ice cap.Be described in further detail below in conjunction with the technical characterictic of specific embodiment this utility model medical electric ice cap.

Accompanying drawing 1 is the structural representation of medical electric ice cap;

Accompanying drawing 2 is medical electric ice cap DC power supply circuit figure.

With reference to figure 1,2, this utility model medical electric ice cap mainly is made of semiconductor cooler 1, water tank 2, water circulating pump 3, circulating water pipe 4 and low temperature water jacket 5.The cold junction of semiconductor cooler 1 closely contacts with the tank wall of water tank 2 and can carry out good heat exchange, and its hot junction then has fin 6.In order to guarantee the cooling-down effect of Electronic ice cap, the refrigerating capacity of semiconductor cooler should more than or equal to 200 kilocalories/hour.Low temperature water jacket 5 is planar double wall water jackets of hemisphere of being made by soft Heat Conduction Material, can be worn on patient's head easily and be communicated with the formation water-flow circuit with water tank 2 and water circulating pump 3 by softish circulating water pipe 4.Be full of water in the water tank 2, and rely on water circulating pump 3 to make its constantly circulation in closed circuit.In order to make the water in the low temperature water jacket 5 keep 2～4 ℃ constant temperature, can adopt the break-make of temperature controller Rt control semiconductor cooler dc source, thereby the water temperature in the water tank 2 is maintained about 0 ℃.In order to prevent the water freezing in the water tank 2, can in water, add an amount of water-soluble material, with the freezing point of suitable reduction water.For the structure that makes whole Electronic ice cap is compact more, can place one to have in the casing of air vent semiconductor cooler, water tank, water circulating pump and dc source.

The utility model advantages of compact and light structure, easy to use, do not have mechanicalness noise, and can keep constant temperature. Therefore, the utility model is specially adapted to the local patient head body temperature that reduces.

Claims

1, a kind of medical ice cap that is used for local reduction patient head body temperature is made of refrigerator and the low temperature headgear that can be worn on patient head at least; Of the present utility model be characterised in that it be by the casing that has air vent, refrigerating capacity more than or equal to 200 kilocalories/hour semiconductor cooler and the medical electric ice cap that constitutes of temperature controller, water-filled water tank, water circulating pump, circulating water pipe and low temperature water jacket; Described water tank, water circulating pump, semiconductor cooler and temperature controller all place in the casing, the cold junction of semiconductor cooler closely contacts with described water tank wall and can carry out good heat exchange, its hot junction has fin, and the break-make of the dc source of semiconductor cooler is controlled by temperature controller; Described low temperature water jacket is the planar double wall water jacket of being made by soft Heat Conduction Material of hemisphere, is communicated with the head that constitutes water-flow circuit and can be worn on patient easily with water tank and water circulating pump by softish circulating water pipe.
