Abstract
The utility model discloses a micro heater for transfusion, which comprises a power transformer and a switch. The primary coil of the power transformer is connected with a power supply, and the secondary coil of the power transformer is serially connected with an elastic electric heating wire in a heating sleeve through the switch; wherein, the heating sleeve is provided with a vertical opening, and the elastic electric heating wire is positioned between the inner layer and the outer layer of the heating sleeve. The power transformer transforms the power into safety voltage to heat the elastic electric heating wire, being safe and reliable; moreover, the heating sleeve is provided with a vertical opening, promising convenient mounting and using. The utility model has advantages of simple structure, easy producing and low cost, thereby being applicable to the heater for medical transfusion.
Description
Technical field
This utility model relates to the heater that a kind of medical transfusion is used.
Background technology
When patient infuses in hospital winter, usually can not feel well because the medicinal liquid of throwing arm into is too cool.For alleviating or removing this discomfort, hospital and patient are pressed in the tube for transfusion root with hot water bag usually and heat to medicinal liquid.Heat to medicinal liquid like this and often will repeatedly change hot water, very inconvenient patient and medical personnel.
Summary of the invention
The purpose of this utility model is to provide a kind of transfusion easy to use little heater.
The purpose of this utility model is achieved in that this little heater of infusing comprises mains transformer and switch, the primary coil of mains transformer connects power supply, the secondary coil of mains transformer is by the elasticity heating wire in the switch serial connection heating jacket, heating jacket is provided with longitudinal opening, and the elasticity heating wire is between the internal layer and skin of heating jacket.
This utility model adopts mains transformer that power supply is become safe voltage, and the elasticity heating wire is heated, and is safe and reliable; Heating jacket is provided with longitudinal opening, and is easy to install.It is simple in structure, makes easily, and cost is low.The heater that is suitable as medical transfusion uses.
Description of drawings
Fig. 1 is the circuit diagram of a specific embodiment of this utility model.Fig. 2 is the heating jacket structure chart among Fig. 1.
1. mains transformer among the figure, 2. heating jacket, 3. elasticity heating wire, 4. switch, 5. tube for transfusion, 6. internal layer, 7. skin, 8. longitudinal opening.
The specific embodiment
In Fig. 1, the primary coil of mains transformer 1 connects the power supply alternating current 220V, and the secondary coil of mains transformer 1 is by the elasticity heating wire 3 in the switch 4 serial connection heating jackets 2.
In Fig. 2, heating jacket 2 is provided with longitudinal opening 8, and elasticity heating wire 3 is between the internal layer 6 and outer 7 of heating jacket 2.
During use, earlier the longitudinal opening 8 of tube for transfusion 5 from heating jacket 2 is inserted in the heating jacket 2.Because the effect of elasticity heating wire 3, after tube for transfusion 5 was inserted in, longitudinal opening 8 can auto-closing.Closing Switch 4 again, and power supply alternating current 220V voltage just becomes safe voltage 36V through mains transformer 1, use for elasticity heating wire 3, begin the medicinal liquid in the tube for transfusion 5 is heated.Owing to be provided with longitudinal opening 8, make tube for transfusion 5 be inserted in and take out all very convenient.
