Detailed description of the invention
Embodiment
As shown in Figure 1, a kind of transfusion heater, for the medicinal liquid/blood plasma of heating transfusion/blood, the heater comprising housing 1 and supported by housing 1; Described heater is to tube for transfusion outer wall transferring heat, and described heater adopts Peltier semiconductor device, by the temperature of the heated side regulating transfusion pipe outer wall of Peltier semiconductor device, thus regulates the temperature flowing through the liquid of tube for transfusion; Described transfusion heater also comprises the attemperating unit run for controlling described heater.
Attemperating unit comprising the controller be located in housing 1, being located at the temperature control button 3 on housing 1 sidewall and the temperature sensor for measuring tube for transfusion outside wall temperature; Controller communicates to connect respectively at heater, temperature sensor and temperature control button 3.
Heat-conducting layer is provided with between heater and tube for transfusion outer wall.Heat-conducting layer is arranged between the heated side of Peltier semiconductor device and tube for transfusion outer wall.
Heat-conducting layer is provided with for bearing tube for transfusion groove 6 or other are for being fixed on the fixture on heat-conducting layer by tube for transfusion.Also be provided with fixing band 7 above groove, tube for transfusion is fixed in groove.
Transfusion heater has first end and the second end, and the second end compares first end closer to infusion needle, and described temperature sensor is for measuring the temperature of the tube for transfusion being positioned at the second end.
Controller is also connected with display screen 2, and display screen 2 is embedded on housing 1, the temperature of the tube for transfusion that described display screen 2 is measured for displays temperature sensor.
Transfusion heater also comprises formation battery case within the case 1, and described heater and attemperating unit are all electrically connected with battery case, can be overall heater and power in battery case after installing battery.
Controller calculates the heatable amount of liquid of dump energy according to the temperature value of the dump energy of accumulator in battery case and setting.
Display screen 2 is also for showing dump energy and the heatable amount of liquid of described dump energy of accumulator in battery case.
The sidewall of housing 1 is provided with charging jacks, and charging jacks one end is inwardly by wire connected battery groove.
Upper surface both sides or the lower surface both sides of housing 1 are provided with fixing band, transfusion heater can be fixed on sick bed, sick chair or patient hand.
