2. Description of the Related Art When injecting a drug solution or the like into a living body or performing a blood transfusion, or performing an extracorporeal blood circulation by an operation or the like, there are many occasions in which other instruments are connected to a conduit (line) for use. In order to secure a long-term vein for infusion, it is necessary to replace the venous needle that is normally used with a winged needle, and if the tube length of the infusion set is insufficient, extend the tube.
I have to connect the cable. When it is necessary to co-inject other chemicals, the tube must be connected with a three-way stopcock to form a line. For these purposes, there are generally two types of connectors (connectors), and one type is a male and female connector with a taper called a slip type. Yes, the connection is performed only by fitting. Another kind is
It is a male and female connector having a screw connection part called a lock type. After the connectors are fitted to each other, the lock nut part fitted to the male connector is screwed to the edge part of the male connector. It is locked by things. However, there are many cases where it is necessary to properly use a lock nut type connector-function and a slip type connector-function at the same connection site, but hitherto, a connector sufficiently satisfying such a function has not been known. Therefore, even when such a function is required, it is unavoidable to select and use one type of connector of the two types, but various problems have occurred. For example,
When connecting the lock-type connector to another medical device, the connecting part of the medical device is defined in terms of shape and / or material by the standard of the member to be screwed, and the types of medical device that can be selected are limited. There is a drawback that Also, if it is predicted that the combined medical device will need to be replaced, especially if it is predicted that it will be replaced in a short period of time, it is not necessary to let the staff take unnecessary time and labor for replacement. However, in an emergency, it is required to replace the medical device promptly, but such a request cannot be dealt with. On the other hand, when connecting the slip-type connector to another medical device, since the connecting force of the connector-is weak, for example, when a reliable connection of the connection portion is required,
Alternatively, it is unsuitable for medical applications that require long-term bonding, and even if it is intentionally used, the bonding strength is insufficient, so that there is a risk of separation, liquid leakage, and the like.
