PURPOSE:To dispense with a troublesome process and attain safe and firm connection by breeding a blending agent such as a plasticizer contained in one member of first and second members onto the surface between mutually adjacent layers, and liquid-tightly adhering and connecting the members to each other. CONSTITUTION:The bore part of a tube 16 is pushed into the male taper part 13A of a hub 13 while extending its diameter to closely adhere the both to each other. The whole body of a medical equipment consisting of a hollow needle 11, a vessel 12, the hub 13 and a tube 16 is sterilized, for example, by autoclave. At this time, the connecting parts of the hub 13 and the tube 16 are heated in a temperature range lower than the melting points to accelerate blocking, and air-tightly bonded to each other. Since the respective materials of the hub 13 and the tube 16 are combined to each other so as to mutually cause blocking, for example, the combination of vinyl chloride resins or a vinyl chloride resin with a polycarbonate resin is adapted. |
