[0037] 如图1和图2所示,测量导管2包括导管主体2a和凹部2b。 [0037] FIGS. 1 and 2, the measuring tube 2 includes a catheter body 2a and the concave portion 2b. 在本实施方式中,导管主体2a呈长条形的管状。 In the present embodiment, the catheter tubular body elongated strip 2a. 另外,凹部2b设置在导管主体2a的外周表面。 Further, the concave portion 2b is provided on the outer circumferential surface of the catheter body 2a. 导管主体2a的材料没有特别限制,例如可以由热塑性的医用塑料套管构成。 Material of the catheter body 2a is not particularly limited, for example, a thermoplastic plastic medical tube. 另外,构成测量导管2的套管也可以由塑料套管以及包覆在塑料套管外的热塑性管材构成。 Further, the catheter tube 2 constituting the measurement may be made of a plastic pipe coated on the thermoplastic sleeve and an outer plastic sleeve.

[0038]另外,凹部2b的底面可以为平坦面。 [0038] Further, the bottom surface of the concave portion 2b may be a flat surface. 由此,能够使所制得的具有底面为平坦面的凹部的测量导管底面更加方便地搭载传感器3。 Thereby, the measuring tube has a bottom recess portion of the bottom surface of the flat surface obtained by the sensor 3 mounted more easily. 另外,能够进一步地减小搭载了传感器后的测量导管2的截面高度,从而减小因测量导管2自身引起的测量误差。 Further, it is possible to further reduce the mounting height of the measuring tube cross-section after the sensor 2, thereby reducing the measurement error caused by the measuring tube 2 itself.

[0039] 此外,测量导管2还可以包括设置在凹部2a上的传感器3。 Sensors [0039] In addition, the measuring tube 2 may comprise further disposed on the concave portion 2a 3. 由此,能够方便利用设置在凹部2b上的传感器3来测量各种生理参数。 Thus, 3 can easily be measured various physiological parameters using a sensor disposed on the concave portion 2b. 传感器3例如可以是压力传感器。 3, for example, the sensor may be a pressure sensor. 这样的压力传感器例如可以用来测量血压。 Such a pressure sensor can be used to measure blood pressure. 传感器3固定在凹部2a上的方式没有特别限制,例如可以通过焊接的方式将传感器3固定在凹部2a上,也可以通过粘接的方式将传感器3固定在凹部2a上。 There is no particular limitation on the sensor 3 fixed to the concave portion 2a, for example, fixed to the recess portion 3 2a, 3 may be fixed by welding on the sensor through the sensor adhesive manner in the recess portion 2a.

[0058] 另外,在一些实施例中,也可以是平坦面32的全部表面积均设置在第一芯轴10上,而仅仅构成凹部的一个侧面的部分设置在第二芯轴20上。 [0058] Further, in some embodiments, it may be a total surface area of ​​the flat surface 32 are disposed on the first mandrel 10, and constitutes only a portion is provided in the side surface of the concave portion 20 on the second mandrel. 在这种情况下,第一平坦面14a成为平坦面32。 In this case, the first flat surface 14a is a flat surface 32. 此外,在一些实施例中,也可以是平坦面32的全部表面积均布置在第二芯轴20上,仅仅构成凹部的一个侧面的部分设置在第一芯轴10上。 Further, in some embodiments, may be a total surface area of ​​the flat surface 32 are disposed on the second mandrel 20, it constitutes only a portion of the side surface of the concave portion provided on the first mandrel 10. 在这种情况下,第二平坦面24a成为平坦面32。 In this case, the second flat surface 32 flat surface 24a. 此外,平坦面32在第一芯轴10和第二芯轴20上的分布还可以按其它比例设置,在此不作详述。 In addition, the distribution of the flat surface 32 on the first mandrel 10 and second mandrel 20 may also be provided in other proportions, not detailed herein.

[0059] 在本实施方式中,第一芯轴10和第二芯轴20的端面可以分别是垂直于各自轴线方向的平面。 [0059] In the present embodiment, the end surface of the first mandrel 10 and second mandrel 20 may be a plane perpendicular to the axial direction, respectively, each. 另外,第一芯轴10和第二芯轴20的端面也可以是与各自轴线方向成一定角度的平面。 Further, the end faces of the first and second mandrels 20 of the mandrel 10 may be a plane at an angle to respective axes.

[0060] 如图3所示,在本实施方式中,平坦面32在第一芯轴10和第二芯轴20的侧表面上露出。 [0060] As shown in FIG. 3, in the present embodiment, the flat surface 32 is exposed on the side surface of the first mandrel 10 and second mandrel 20. 由此,在制造测量导管的过程中,可以容易地在测量导管的外周表面上形成底面为平坦面的凹部。 Thus, during the manufacture of the measuring tube, the measurement can be easily formed on the outer peripheral surface of the conduit to a bottom surface of the concave portion flat surface.

[0061] 此外,在第二芯轴20的表面上与第二承载部24间隔规定距离的位置,设有定位部40。 [0061] Further, on the second surface 20 of the mandrel 24 and the second carrying portion spaced a predetermined distance from the position, the positioning portion 40 is provided. 在制造测量导管2的过程中,通过定位部40,可以对测量导管2沿着第二芯轴20的轴线方向进行定位。 In the process of manufacturing the measuring tube 2, 40, 2 can be positioned along the axial direction of the second mandrel portion 20 by the positioning of the measuring tube. 由此,可以方便地在测量导管2外周表面的规定位置设置凹部。 This can conveniently be measured in a predetermined outer circumferential surface of the concave portion of the catheter the second position.

[0063] 另外,在一些实施例中,定位部40也可以是沿着第二芯轴20的外周表面设置的突起。 [0063] Further, in some embodiments, the positioning portion 40 may be provided along the outer circumferential surface of the second projection 20 of the mandrel. 由于定位部40相对于第二芯轴20的侧表面突起,因此,在制造测量导管2时,可以通过使测量导管抵持定位部40来实现定位。 Due to the positioning protrusion portion 40 with respect to the side surface of the second mandrel 20, and therefore, in the manufacture of the measuring tube 2, it can be obtained by measuring tube abutting the positioning portion 40 to achieve positioning. 另外,该突起可以形成为沿着第二芯轴20的外周表面连续形成的突起,也可以形成为沿着第二芯轴20的外周表面间隔形成的若干个突起。 Further, the protrusion may be formed to protrude along the outer periphery of the second surface of the mandrel 20 is continuously formed, it may be formed as a plurality of projections along an outer circumferential surface of the second spacer 20 is formed on the mandrel. 此外,突起可以采用轴肩结构。 Further, the protrusion shoulder structure may be employed. 再者,也可以在作为突起的轴肩结构上进一步设置环装槽,以使定位更加牢靠。 Further, the ring may be further provided with grooves mounted on a shaft projecting shoulder structure as to make positioning more robust.

[0064] 此外,定位部40的位置可沿着第二芯轴20的轴线方向调整。 [0064] In addition, the position of the positioning portion 40 can be adjusted along the axial direction of the second spindle 20. 即,定位部40可以被设置成可移动的结构,即,根据需要,定位部40可以沿着第二芯轴20的轴线方向移动,从而调整定位部40在第二芯轴20上的位置。 That is, the positioning portion 40 may be arranged to be movable structure, i.e., according to need, the positioning portion 40 can be moved along the axial direction of the second spindle 20 so as to adjust the position of the positioning portion 40 on the second mandrel 20. 由此,能够调整凹部在测量导管上的形成位置。 Accordingly, it is possible to adjust the position of the concave portion is formed on the measuring tube.

[0065] 在本实施方式中,定位部40也可以设置在第一芯轴10上。 [0065] In the present embodiment, the positioning portion 40 may be provided on the first mandrel 10. 在这种情况下,定位部40同样也能起到对测量导管2进行定位的作用。 In this case, the positioning portion 40 can also play a role in positioning the measuring tube 2.

[0066] 如上所述,在第一芯轴10上形成有第一把持部12,在第二芯轴20上形成有第二把持部22 (参见图3和图4)。 [0066] As described above, the mandrel 10 is formed on the first gripping portion 12 has a first, a second gripping portion 22 (see FIG. 3 and FIG. 4) formed on the second mandrel 20. 通过调整并固定第一把持部12和第二把持部22,可以对第一芯轴10和第二芯轴20进行固定和定位。 By adjusting and fixing the first gripping portion 12 and a second gripping portion 22, can be positioned and fixed to the first mandrel 10 and second mandrel 20.
