非常に繁雑である。本考案は、かかる繁雑さを解
消することを目的としてなされたものである。 In the medical field, such as infusions, blood transfusions, and various artificial organs, tubes of various diameters are used. Most of these tubes are made of soft plastic such as soft vinyl chloride, and because they have low elasticity, it is difficult to connect many types of tubes with one type of connector, and there are various types of tubes depending on the thickness of the tube. Currently, the following connectors are used. Therefore, there are many types of connectors, and they are very complicated to manufacture and use. The present invention has been made with the aim of eliminating such complexity.

これよりも大きいことを特徴とする医療用チユー
ブコネクタである。 That is, the present invention provides a tube connector having a tube insertion portion in the form of serially connected hollow truncated cones, in which the bottom diameter D of the truncated cones gradually increases from the end of the connector toward the center; and the angle θ formed by the line connecting the bottom ends of adjacent truncated cones and the axial direction of the connector is minimum at the end of the connector and larger at a portion near the center. It is a tube connector.
本考案のコネクタは、上記の角度θがコネクタ

くない。 In the connector of the present invention, the above angle θ is minimum at the end of the connector, and is larger near the center, so even if the length of the connector is short, it can accommodate a wide range of tube inner diameters, and Since θ is small near the area, the tube can be stably fixed. And θ is 2 to 7 near the end.
°, particularly preferably in the range of 3 to 5 °, and in the region near the center 4 to 9 °, particularly preferably 6 to 8 °
It is preferable for the tube to be stably fixed within the range of . If θ is larger than the above range, the tube will easily come off, and if θ is smaller than the above range, the range of inner diameters of the tube that can be connected will be narrowed, which is not preferable. Also, if θ is constant throughout, setting θ to an appropriate range will inevitably lengthen the tube connection.
On the other hand, if you try to shorten the tube connection part, θ will increase, which will make the tube more likely to come off, which is not preferable.
