PROBLEM TO BE SOLVED: To provide a multi-puncture mixed injection tube allowing mixed injection parts to be put at one place together, assuring limitless injector positions for needling work many times and facilitating assembly in manufacture. SOLUTION: This multi-puncture mixed injection tube comprises an inner cylinder 9 formed of a rubber elastic material adaptable to a human body and superior in tear-off strength, a protecting outer cylinder 8 with a sideways window hole 8c mounted outside the inner cylinder 9, and tube connectors 10 rotatably mounted at both ends of the inner cylinder 9. A tubing line 7 itself formed of the rubber elastic material is used for the multi-puncture mixed injection tube or the protecting outer cylinder 8 with the sideways window hole 8c is rotatably mounted on the tubing line 7 to form the multi-puncture mixed injection tube. |
