To achieve these goals, this utility model takes following technical solution:
Based on the temperature measuring equipment of blood vessel interventional technique, comprising: blood vessel interposing catheter; The tee T be connected with described blood vessel interposing catheter, a path of described tee T is connected with drug injection pipeline; Fibre optic temperature sensor, described fibre optic temperature sensor stretches into from another path of described tee T and passes the described blood vessel interposing catheter be connected with tee T, is formed with the space that medicine circulates between the periphery wall of described fibre optic temperature sensor and the inwall of described blood vessel interposing catheter; The optical fiber temperature-measurement device be connected with described fibre optic temperature sensor.
Further technical scheme is: described tee T is Y-shaped three-way pipe.
Further technical scheme is: the diameter of described fibre optic temperature sensor is 0.3 ~ 0.5mm.
Further technical scheme is: the bending diameter of described fibre optic temperature sensor is less than 15mm.
Further technical scheme is: the periphery wall of described fibre optic temperature sensor scribbles hydrophilic coating.
Further technical scheme is: described blood vessel interposing catheter is hollow state, and its internal diameter is 0.9mm.
From above technical scheme, this utility model utilizes blood vessel interventional technique, fibre optic temperature sensor is adopted to stretch into Ink vessel transfusing by blood vessel interposing catheter, arrive destination organization position, temp sensing function is achieved while blood vessel intervention operation, again need not set up the thermometric passage of wound, and modern medicine circle that is based upon that blood vessel gets involved passage has very ripe scheme, the chance of infection can be reduced, temperature measurement accuracy is high, thermometric is fast, operator can be allowed intuitively to see the temperature parameter of destination organization, a visual assessment is had to physical curative effect, more easily verify therapeutic effect, optical fiber temperature-measurement environment for use requires low simultaneously, and its non-metallic material attribute can work under X-ray and electromagnetic wave operating mode, and not by external interference, and size sensor can be accomplished very tiny, reaches 0.1mm, and measuring distance can realize 2 meters and above scope.

Fig. 1 is the structural representation of this utility model temperature measuring equipment;
Fig. 2 is the sectional view that this utility model fibre optic temperature sensor is arranged in blood vessel interposing catheter.
Detailed description of the invention
As shown in Figures 1 and 2, temperature measuring equipment of the present utility model comprises fibre optic temperature sensor 1, optical fiber temperature-measurement device 2, Y-shaped three-way pipe 3, blood vessel interposing catheter 4 and drug injection pipeline 5.Blood vessel interposing catheter 4 is connected with Y-shaped three-way pipe 3, a path of Y-shaped three-way pipe 3 is connected with drug injection pipeline 5, fibre optic temperature sensor 1 stretches into from another path of Y-shaped three-way pipe 3 and passes the blood vessel interposing catheter 4 be connected with Y-shaped three-way pipe 3, the space that medicine circulates is formed between the periphery wall of fibre optic temperature sensor 1 and the inwall of blood vessel interposing catheter 4, fibre optic temperature sensor 1 is connected with optical fiber temperature-measurement device 2, is shown the temperature of fibre optic temperature sensor 1 position by optical fiber temperature-measurement device 2.Fibre optic temperature sensor of the present utility model is product sold on market.
As preferred embodiment of the present utility model, employing diameter is the fibre optic temperature sensor 1 of 0.3 ~ 0.5mm, the bending diameter of optical fiber is less than 15mm, the periphery wall of fibre optic temperature sensor 1 scribbles hydrophilic coating 10, optical fiber is made to have hydrophilic, lubricity and good blood bio-compatibility, simultaneously without water absorption, nontoxic.
When carrying out in-vivo tissue thermometric, blood vessel interposing catheter 4 is stretched into the destination organization in arrival (animal) body along blood vessel, optical fiber temperature measuring sensor 1 arrives the endovascular distal face in blood vessel interposing catheter place by means of Y-shaped three-way pipe 3 and blood vessel interposing catheter 4, blood vessel end face in therapeutic goal body namely in body, then connecting fiber temperature measuring equipment 2, because fibre optic temperature sensor front end is soft and can shape, after its destination organization arrived by blood vessel interposing catheter, just can test the temperature of this Ink vessel transfusing and perienchyma, the temperature measured is shown by optical fiber temperature-measurement device, handled easily person observes.
