Background technology
Blood extracorporeal circulation has thermal loss, the method of dialysis machine, blood filtering machine use when doing dialysis to patient is by regulating dialysate temperature compensation blood thermal loss, then do not have the external thermal loss of measure compensation blood when doing hemoperfusion with dialysis machine, blood filtering machine merely to patient both at home and abroad at present; What domestic blood perfusion apparatus adopted when doing hemoperfusion to patient is a blood circuit part to be immersed in compensate the blood thermal loss in the water that is heated to uniform temperature.
Haemodialysis control unit, blood filtering machine do not have the blood heat indemnifying measure might cause patient when doing hemoperfusion because external blood coagulation and patient's shiver with cold appear in the external thermal loss blood heat decline of blood; Blood perfusion apparatus is used when doing hemoperfusion to patient a blood circuit part is immersed in the method that compensates the blood thermal loss in the water that is heated to uniform temperature, the heat conductivity of water is little on the one hand, do not reach the purpose of compensation blood extracorporeal circulation thermal loss, also might cause patient and external blood coagulation and patient's shiver with cold occur because the external thermal loss of blood causes blood heat to descend, water easily freezes when temperature is low on the other hand, can require the conditions for equipment use temperature higher, thereby limit the use occasion of equipment.
Summary of the invention
The technical problems to be solved in the utility model is: overcome the problem that prior art exists, design the external heating apparatus of a kind of blood purification simple in structure, safe and reliable, good constant-temperature effect.
The technical scheme that its technical problem that solves this utility model adopts is: the external heating apparatus of this blood purification, comprise heater and control device, it is characterized in that: heater comprises heater, calandria and hot plate, calandria is installed in the heater top, hot plate is installed in the calandria top, have the semicircular arc shrinkage pool for the splendid attire pipeline above the hot plate, hot plate bottom surface mounting temperature sensor is between hot plate and the calandria, scribble thermal grease conduction between heater and the calandria; Control device comprises power module, CPU, temperature collect module, heating module, operation and display module, the 220V civil power is powered to power module, power module links to each other with CPU with temperature collect module, and CPU links to each other with heating module, and CPU and operation and display module are interconnected.
Heater is PTC, and calandria is tabular, and length is less than hot plate.
Temperature collect module is temperature sensor 18B20; Operation and display module are that button and number implement form; Power module is that transformator and Voltage stabilizing module 7805 form, and CPU is the A789C52PI chip.
Compared with prior art, the beneficial effect that the external heating apparatus of blood purification of the present utility model has is: owing to being provided with heater and control device, automatic heating and temperature automatically controlled can be realized, when using haemodialysis control unit to do hemoperfusion merely to patient, the blood extracorporeal circulation thermal loss will be compensated reliably; This method is used on the blood perfusion apparatus, will greater efficiency compensation blood extracorporeal circulation thermal loss when doing hemoperfusion with blood perfusion apparatus to patient.Both satisfy compensation blood extracorporeal circulation thermal loss, enlarged again equipment serviceability temperature environment.And simple in structure, safe and reliable, solved water that prior art exists the heat blood coagulation that occurs, the problem such as freeze.
