At present, the method of China's body temperature lowering or intensification adopts body surface method for regulating temperature substantially, for example use ice bag or ice blanket cold compress to lower the temperature, surface cooling can reach cooling object in to a certain degree, but existing surface cooling temperature is wayward, its operating process is comparatively loaded down with trivial details, and Induction Process is long, easily excessively cooling or intensification.Excessively cooling does not only reach therapeutic effect, also easily causes the corresponding complication of patient, even increases mortality risk.
Summary of the invention
The object of the invention is to overcome the above-mentioned deficiency of prior art, a kind of temperature control conduit with pressure transducer is provided, this temperature control conduit is inserted in postcava, by the FLUID TRANSPORTATION after cooling or heating is arrived to heat exchange sacculus, utilize the heat exchange between sacculus and vein, as the application of body temperature lowering or intensification.
For achieving the above object, the invention provides following technical scheme:
With the temperature control conduit of pressure transducer, include water cavity road, backwater tract and sacculus, wherein enter water cavity road and comprise far-end water inlet, backwater tract comprises far-end water return outlet, sacculus is positioned at the far-end of conduit, and the opening of described far-end water inlet and far-end water return outlet is arranged in sacculus, enters water cavity road and also comprises near-end water filling port, backwater tract also comprises near-end outlet, and described catheter proximal end is provided with pressure inductor.
In the above-mentioned temperature control conduit with pressure transducer, the pressure inductor of described catheter proximal end setting is for responding to the blood pressure of vein.
In the above-mentioned temperature control conduit with pressure transducer, described far-end water inlet is greater than far-end water return outlet.
In the above-mentioned temperature control conduit with pressure transducer, described temperature control conduit comprises two sacculus, and described two sacculus successively interval arrange, each sacculus with enter water cavity road and backwater tract is communicated with.
In the above-mentioned temperature control conduit with pressure transducer, the near-end water filling port of described catheter device is connected with outlet and the water inlet of heat regulating device respectively with outlet; Described pressure inductor is connected with heat regulating device, by the display on heat regulating device, can show in real time patient's blood pressure.
compared with prior art, beneficial effect of the present invention:the present invention utilize sacculus in patient's postcava constantly and blood carry out heat exchange, reach the object of controlling human pressure, in the time giving body temperature lowering, fluid does not participate in human body contact, do not participate in body metabolism, can avoid under specific circumstances fluid to participate in body metabolism and bring infringement to patient's the heart, lung and renal function, greatly reduce the corresponding complication of patient and dead risk; Can detect in real time patient's blood pressure by pressure inductor, be convenient to understand in time the blood pressure in patient body, prevent that in blood heat adjustment process, fortuitous event appears in blood pressure; In the time that temperature control conduit arranges multiple sacculus, can further increase the contact surface of heat exchange, contribute to change fast the temperature in body.
