Can be applicable to the temperature survey of various objectives by built-in sensor of the present invention, particularly it to use in the artificial fever therapy of cancer as a kind of temperature sensor be very suitable.In this therapy, to accurately measure the temperature of living tissue outside or deep damage location in order to improve result of treatment.Promptly, in the artificial fever therapy of cancer, for example use electromagnetic wave to heat living tissue method, this method utilization enters the heat that produces when living tissue electromagnetic wave is absorbed by its each position, consider treatment processing and equipment operation, must accurately measure the temperature at each position of living tissue in the case.Bright outside hereinafter will describing originally, particularly be illustrated with reference to all accompanying drawings.
Fig. 1 represents first embodiment by built-in type temperature sensor of the present invention.With reference to Fig. 1 and 2, a thermopair 1 is placed in the garden cylindrical tube 2 by the fluororesin manufacturing.In the present embodiment, as shown in drawings, garden cylindrical tube 2 is changed into a kind of flat shape at its left end.If pipe 2 is processed to form a hole 3 by its original appearance, then body fluid or analog just might enter pipe 2 by hole 3, and therefore for avoiding aforesaid shortcoming, tube end is sealed.In addition, be processed into flat pattern and have the advantage that makes hole 3 be convenient to be shaped, and pass a line spare easily, for example single line passes hole 3.According to the diameter in hole 3 and the external diameter of pipe 2, can at random select the size of flat part.Making flat part can be undertaken by laxative remedy: in the heat-sealing of the top of pipe 2, it is placed between two flat boards is pressed into aforesaid flat pattern simultaneously, be processed to form a hole at flat part then.According to the external diameter and the wall thickness of pipe 2, the size of selecting hole 3 at random, generally from 0.5 to 3 millimeter of its scope; Fixing with single line under the situation of pipe, from 1 to 2 millimeter of diameter is then better.One end of thermopair is abutted against terminal or analog is connected with a temperature indicator (TI).When using the built-in type temperature sensor of present embodiment, tightened for thermo-responsive section, for example under the situation that the esophagus outer wall is performed surgical operation, and one passed armpit with thermo-responsive section lead that links to each other always and expose at human body surface.Then, with the method known, such as adhesive tape or analog, lead fixed behind human body surface, lead be connected with a temperature indicator (TI) (not shown) in case when using artificial fever therapy at every turn the energy measurement temperature.For the line that is round that makes beginning is easy to be connected with hole 3, as shown in Figure 3, can further arrange one from the hole 3 until the joint-cuttings 7 in the built-in sensor outside.
Fig. 4 represents by second embodiment of the present invention.With reference to the accompanying drawings, be processed to form a contraction section 6 at pipe 4 left ends.Contraction section 6 is processed as to make the diameter of its diameter less than the adjacent segment of thermal shrinkage fluororesin tube.This pipe can be made; For example, two garden steel with 2 millimeters of external diameters, 10 millimeters of length insert in the thermal shrinkage fluororesin tube of 2.5 millimeters of external diameters, make the garden steel by these separately 3 millimeters simultaneously, then their are heated the contraction section 6 that makes it to form as shown in Figure 4.The external diameter of contraction section is 1.8 millimeters.Then, in order to make temperature sensor, a high resistant reed thermistor 5 is imbedded in the pipe, this pipe is as protection tube.In actual use, the temperature sensor method of tying up contraction section with single line fixes.Because fluororesin is hard, and line spare, for example fine rule blocks not inlet pipe surface, causes the leeway of displacement in a small amount so often have one in notched section, but fine rule can not skid off from recess.
As the 3rd embodiment, protection tube is all or partly by the resilient material like rubber, for example silicone rubber tube manufacturing, rather than be processed to form hole or groove; And in providing a linkage section to tie up pipe with a suture.For pipe is tightened fully, for the resilient material like rubber, required thickness is greater than 0.3 millimeter.In addition, for the elongation that prevents that protection tube from causing owing to external force, thereby cause the displacement of temperature measuring positions; Need be a kind of fibrous material that not too can extend, for example glass fibre, carbon fiber or analog pass tube interior along the direction of protection tube inside conductor, and fiber is combined with protection tube to prevent the protection tube elongation.For example, can make of laxative remedy by built-in type temperature sensor of the present invention, be a diameter that to pierce into an external diameter together with the carbon fiber that 10000 strands of filaments is arranged and scribble silicone coatings that axially sticks along it be that 2 millimeters, internal diameter are in 1 millimeter the silicone tube for 0.1 millimeter thermopair promptly.When temperature sensor in that 10 millimeters away from top place is performed the operation and is tied up and during with 500 gram forces, displacement is less than 0.5 millimeter with fine rule be.
In addition, the insulating powder that resembles MgO and so on can be filled in the protection tube, and can open wide on the top.
