Description

A kind of transfusion preheating device

Technical field

Medical treatment and nursing instrument field under this utility model relates in particular to a kind of transfusion preheating device.

Background technology

Known, transfusion is the operation of often carrying out in the present medical treatment, and regular meeting causes patient's discomfort because temperature of liquid is lower but infuse often in autumn and winter season, and serious also can cause life danger.In order to prevent the generation of this situation, the medical personnel that have can make applying hot water bottles or hot water bag liquid be carried out preheating near being placed on the flexible pipe of transfusion device, but needs of patients is infused for a long time sometimes, and hot water bottle or hot water bag temperature can very fast reductions, lose pre-heat effect.The patent No. is that the utility model patent of ZL 94238315.X discloses a kind of medical infusion preheater, but simple in structure, hot water need be poured into and just preheating can be carried out, and complex operation, effect is not lasting; The patent No. is that the utility model patent of ZL 200920148765.4 discloses a kind of medical transfusion preheating device, though solved the persistent problem of pre-heat effect, complex structure, and need a large amount of electronic devices, cost is higher, and can't hang, and transfusion bottle can only use after the first preheating; Application publication number is that the patent of invention of CN 102430174 A discloses a kind of drop heater, can hang and preheating, uses hot water to carry out preheating but remain, complex operation, and persistency is poor; The patent No. is that 200320105443.4 utility model patent discloses a kind of drop heater, and complex structure needs the extrapolation power supply, and application is not strong.Therefore, a kind of structure is simple relatively, and is with low cost, can use easily at any time and the transfusion preheating device of lasting preheating becomes a lot of medical personnel and patient's common demand.

The utility model content

At the problem that background technology exists, this utility model provides a kind of transfusion preheating device.

For solving the problems of the technologies described above, this utility model adopts following technical scheme:

A kind of transfusion preheating device comprises closed hollow housing, and case top is provided with link, at the bottom of the housing

Portion offers porose, and the housing side offers baffle door, and housing comprises heat insulation layer and heat-conducting layer, heat insulation layer outside, heat-conducting layer is interior, constitutes cavitys in the middle of both; Be provided with hook switch, heating wire, the battery of series connection successively in the cavity; Hook switch is made up of hook and spring, and hook stretches out heat-conducting layer, is used for hanging infusion bottle or transfusion bag, and spring pull-up hook does not make circuit be in off-state when hanging weight, circuit connection behind the suspension infusion bottle; Heating wire and heat-conducting layer fit tightly.

Described housing is cylindrical; Heat-conducting layer forms cylindrical heating space in inside, hook is positioned at heating space

In.

A part of cylindrical side of described heat insulation layer is offered and is baffle door, links to each other by other parts of axle and heat insulation layer

Connect, infusion bottle can be put into heating space after opening baffle door; Circular hole is offered in the heat insulation layer bottom, is used for passing through infusion tube.

Described heat insulation layer is made by hard, material that thermal insulation is good; Described heat-conducting layer is by the good material of heat conductivity

Make.

Operation principle of the present utility model is as follows:

During use, link of the present utility model is hung on the transfusion hook, medical personnel open baffle door, and infusion bottle or transfusion bag are hung on the hook, and infusion tube is passed from the circular hole of heat insulation layer bottom, shut baffle door, this moment, infusion bottle or transfusion bag pulled down the spring in the hook switch under the effect of gravity, and internal circuit is connected, and battery is powered to heating wire, heating wire produces heat, gives infusion bottle or transfusion bag preheating by heat-conducting layer; After transfusion finishes infusion bottle or transfusion bag are taken off, the hook in the hook switch is pulled up under the effect of spring, and internal circuit disconnects, and the circuit each several part quits work, and this utility model stops warm-up operation automatically.

Compared with prior art, this utility model has been obtained following technique effect:

This utility model is easy to use, it is hung on the transfusion hook get final product, and only needs during use infusion bottle or transfusion bag are hung over this utility model inside, warm is begun automatically and is stopped by circuit control, pre-heat effect is lasting, and the time spent can not cut off the power supply automatically, saves electric energy; This utility model has solved when transfusion autumn and winter cryogenic liquid to the misery that the patient brings, and has eliminated the danger that causes thus, and simple in structure, with low cost, satisfactory for result, and humanization designing is conducive to make up good doctor-patient relationship.
