Detailed description of the invention
Embodiment
As shown in Figure 1, a kind of infusion heating device, 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 infusion heating device 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.
Infusion heating device 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.
Infusion heating device 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, infusion heating device can be fixed on sick bed, sick chair or patient hand.
Infusion heating device is also provided with switch 4, in not used time closedown, and energy savings; Also be provided with charging indicator light 5, when giving the charge in batteries in battery case, charging indicator light 5 can be lighted simultaneously.
When paltie effect refers to electric current by thermocouple, a node distribute heat, makes this junction temperature reduce, and another node absorbs heat, makes the phenomenon that this junction temperature raises.Peltier semiconductor device is made up of the multipair thermocouple, wire etc. of two-layer heat-conducting substrate and inside.These thermocouples are connected on circuit, in parallel on conduction of heat, thus when being energized, the end region temperature change that thermocouple connects a substrate is consistent, realizes cooling or the intensification of this substrate.Thermocouple generally adopts the P type that mixes trace element and N-type semiconductor to be in series.In order to extend the life-span of Peltier semiconductor device, can carry out circumferential seal process between the two-layer heat-conducting substrate of device, encapsulant can with silica gel or epoxy resin etc.In order to improve refrigerating capacity or heating capacity, the form of plural serial stage can be adopted to form multistage Peltier semiconductor device.
Operation principle, temperature value is preset by temperature control button 3, in tube for transfusion, liquid flows according to the direction of arrow, the temperature of liquid conducts to temperature sensor through the tube wall of tube for transfusion, if the temperature value of temperature sensor senses is lower than the temperature value preset, heater is selected to be placed in heated condition by controller, the heat of heater conducts to the liquid in the tube wall of tube for transfusion and pipeline by heat-conducting layer, temperature of liquid after heating rises, liquid is along direction of arrow flowing in pipe, when flowing through the pipeline of temperature sensor place, tube wall through tube for transfusion conducts in temperature sensor by the temperature of liquid of heat, when the temperature of temperature sensor senses reaches the temperature value preset, heater is selected to be placed in disconnection heated condition by controller.After heater disconnects heating, along with the flowing of liquid, cool liquid will constantly take away the heat of heat-conducting layer, and temperature of liquid will decline thereupon.When liquid stream is when the pipeline of temperature sensor place, tube wall through tube for transfusion is taken away the heat in temperature sensor by cool temperature of liquid, the temperature of temperature sensor will decline thereupon, when the temperature value of temperature sensor perception is lower than the temperature value preset, heater is selected to be placed in heated condition by controller again.Like this, the temperature that the liquid in tube for transfusion just can keep relative stability in certain scope according to the requirement of expection.Attemperating unit in the present invention can be positioned among the application apparatus of other medical fields except tube for transfusion, as medical warmer etc.
Technical scheme of the present invention, while providing suitable transfusion temperature for different body constitution patient, also adopts battery powered, convenient and safe.
