Description

The tube for transfusion heater

Technical field:

This utility model belongs to medical appurtenance technical field, is a kind of tube for transfusion heater.

Technical background:

Cross cold because of liquid and bring uncomfortable feeling to patient when cold day is infused, and the existing mode that adopts usually is direct bottle wall heating in transfusion that temperature has reduced when the heating liquids such as course of conveying of longer distance reach in the body, effect is very undesirable.

Summary of the invention:

The purpose of this utility model provides simple in structure, and volume is little, and loading and unloading are quick, tube for transfusion heater easy to use.

Technical solution of the present utility model is: a kind of tube for transfusion heater, comprise box body, power line and plug, and on this box body magnetic is installed, be provided with the PTC heater that is electrically connected with power line and plug in the box body, this PTC heater is arranged to groove structure.

Preferably, the PTC critesistor that described PTC heater comprises the aluminum heat sink strip and is bonded together with it, this PTC critesistor is electrically connected with power line and plug.

The beneficial effects of the utility model are: because PTC heater is in the temperature range of beginning, rising with temperature, the resistance value of this product can slightly descend, after being reduced to a lowest resistance value, begin again also to raise with its resistance value of rising of temperature, its resistance value sharply becomes big with the rising of temperature after surpassing curie point, can change 10 in the tens scope internal resistance values of spending ³-10 ⁸Doubly, show very strong PTC effect, thereby make product be in " insulation " state, " outage " state in other words, when temperature was low slightly, resistance also reduced like this, power begins to increase, thereby holding temperature makes that in steady state this device heats is obvious, and heating-up temperature is stable and can require to select preset temperature according to difference.

The specific embodiment:

A kind of tube for transfusion heater that this utility model relates to is heated to tube for transfusion by PTC heater, below in conjunction with accompanying drawing, feature of the present utility model is elaborated:

See figures.1.and.2, tube for transfusion heater 20 of the present utility model, comprise box body 23, power line and plug 24, on this box body 23 magnetic 21 is installed, be provided with the PTC heater 22 that is electrically connected with power line and plug 24 in the box body 23, this PTC heater 22 is arranged to groove structure, so that put into tube for transfusion 11.

With reference to Fig. 3, the PTC critesistor 32 that PTC heater 22 comprises aluminum heat sink strip 33 and is bonded together with it, this PTC critesistor 32 is electrically connected with the electrode 31 of power line and plug 24.

During use, open the box body 23 of tube for transfusion electro-heat equipment 20, tube for transfusion 11 is put in the middle of PTC heater 22 grooves, and then the box body 23 that closes is to close upper tubing electro-heat equipment 20, wherein the magnetic on the box body 21 plays the effect that tightens up that connects, plug in then line and plug 24, Fig. 4 is the circuit diagram of tube for transfusion heater.Power supply 41 is a household electricity, opens switch 42, and relay indicating light 25 and light emitting diode 44 light can realize heated at constant temperature.
