Abstract
The invention relates to the field of medical apparatuses, in particular to a temperature-controlled catheter. The temperature-controlled catheter comprises a water-entering cavity channel, a water-returning cavity channel and a balloon, wherein the water-entering cavity channel comprises a far-end water inlet, the water-returning cavity channel comprises a far-end water-returning opening, the balloon is positioned at the far end of the catheter, the openings of the far-end water inlet and the far-end water-returning opening are positioned in the balloon, the water-entering cavity channel also comprises a near-end water-injecting opening, and the water-returning cavity channel also comprises a near-end water outlet. According to the temperature-controlled catheter, the purpose of controlling the temperature of a human body is achieved by continuously exchanging heat with blood in the inferior vena cava of a patient by utilizing the balloon; when the temperature of the human body is decreased, a fluid does not participate in the contact with the human body and the metabolism of the human body, so that the damage brought to the cardiac, pulmonary and renal functions of the patient by the participation of the fluid in the metabolism of the human body can be avoided under a specific condition, and therefore the risks of corresponding complication and death of the patient are greatly lowered; when the temperature-controlled catheter is provided with a plurality of balloons, the contact surface of heat exchange can be further increased, thus being helpful to rapidly changing the temperature in the body.
Description
Technical field
The present invention relates to medical instruments field, particularly temperature control conduit.
Background technology
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 is provided, and 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:
Temperature control conduit, 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, 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 temperature control conduit, described far-end water inlet is greater than far-end water return outlet.
In above-mentioned temperature control conduit, 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 above-mentioned temperature control conduit, 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.
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, 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; 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.
