The specific embodiment
For structure and the characteristic that catheter tube for medical treatment like this is described, enumerate specific embodiment, and consider figure in light of actual conditions and detail as follows:
Shown in Figure 1, catheter tube for medical treatment of the present invention has the hollow tube that a body 1 is formed with tube chamber 2, and soft and resilient material forms its tube wall 11 by silicone rubber etc.In an embodiment, its external diameter is 1.7 millimeters, and tube chamber 2 internal diameters are 0.9 millimeter, and total length is 1,500 millimeter, but, during actual embodiment of the present invention, do not limit in this.
In addition, synthetic fibers such as all aromatic Silon are strengthening material, are embedded in the tube wall 11, to form along axially and be parallel to the reinforcement line 3 of tube chamber 2.
As shown in Figure 2, be not provided with the conventional hoses 8 of strengthening line, rely on external strength to be drawn at the following of the impaired situation of body to the direction of arrow, then this impaired part is damaged easily and is broken.But, drawn to the direction of arrow by external strength equally, be provided with the catheter tube for medical treatment of the present invention 1 of strengthening line 3, be destroyed though then be partially damaged, because of strengthening the effect of line 3, do not broken.
