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 heat exchange catheter equipment is provided, this heat exchange catheter equipment 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:
Heat exchange catheter equipment, comprise import medicine perfusion tract, enter 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 catheter device, 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, and backwater tract also comprises near-end outlet.
In above-mentioned heat exchange catheter equipment, described perfusion tract is positioned at the central authorities of catheter device, enters the periphery that water cavity road and backwater tract are positioned at catheter device.
In above-mentioned heat exchange catheter equipment, described far-end water inlet is greater than far-end water return outlet.
In above-mentioned heat exchange catheter equipment, described heat exchange catheter equipment comprises two sacculus, and described two sacculus successively interval arrange, each sacculus with enter water cavity road and backwater tract is communicated with.
In above-mentioned heat exchange catheter equipment, the near-end water filling port of described catheter device is connected with water inlet with the outlet of heat regulating device respectively with outlet.
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 body temperature, when giving body temperature lowering, fluid does not participate in human body contact, do not participate in body metabolism, can avoid under specific circumstances fluid participation body metabolism to bring infringement to patient's the heart, lung and renal function, greatly reduce the corresponding complication of patient and dead risk; Perfusion channel is for importing vein by medicine, and whole heat exchange catheter equipment purposes is various, easy to use; When heat exchange catheter equipment arranges a plurality of sacculus, can further increase the contact surface of heat exchange, contribute to change fast the temperature in body
