Abstract

PURPOSE:To obtain the connection having desired mechanical strength without using a solvent by connecting two synthetic resin members through a connecting member, consisting of synthetic resin material of melting point lower than that of the synthetic resin member, by heating at the melting point or more of the connecting member. CONSTITUTION:A transfusion liquid pipe 10 is a long size pipe-shaped synthetic resin- molded product consisting of high molecular material of, for instance, polyvinyl chloride(PVC) or the like, and the pipe 10 is connected in its point end part 14 inserted into a blood port 16 of a drip cylinder 12. A calking molded member 18 is a connecting member attaining strong liquid-tight connection between the two connected members 10 and 12, and a material of the connecting member, for heating connection thereafter, usefully applies a synthetic resin material of solid at the normal temperature having a melting point lower than the material of the two members 10 and 12 to be connected. For convenience of a heating process, in the case of heating not only the connection part but a main assembly total unit, a material is preferable having a melting point further lower than the lowest of all the members constituting the drip cylinder 12. For instance, polyethylene terephthalate(PETG) having no elongation is useful.

It is particularly suitable for medical instruments.

In the case where both parts are polymer molded products, the connection is made using a solvent. For example, in the case of polyvinyl chloride products, tetrahydrofuran (↑HF), cyclohexane, etc. are used as this solvent.

Minimization is required. Therefore, it is extremely undesirable for the above-mentioned residual solvent to enter the living body from, for example, the blood circuit, and therefore, the amount of solvent used has been limited. It is also required to completely remove residual solvent. However, this removal work is complicated and requires a lot of man-hours.

Its melting point is about 80°C, and when the infusion tube 10 and drip barrel 12 are made of polyvinyl chloride, its melting point is about 145°C.
It is about @C. Therefore, it is preferable to heat the entire assembly including the drip tube 12, the infusion tube IO, and the caulking molded member 18 for about 30 minutes in saturated steam at about 120'''C in autoclave sterilization. The heating sterilizes the entire drip barrel 12 assembly and melts the caulking molded member 18. Thereafter, the entire assembly is cooled to a temperature below the melting point of the caulking molded member 18. For example, it is left at room temperature. As a result, the caulking molded member 18 is solidified, and therefore the infusion tube 10 is firmly fixed to the drip tube 12, and a liquid-tight connection is completed.Of course, if the entire assembly does not need to be heat sterilized, 18 may be locally heated and cooled.
