With the bi- Al encapsulation section of various sizes the needle which is used is not the baiaru adapter null each

摘要

The needle it is not the valve, the bi- Al sealing section of the sharp cannula, or the various diameters which are used in order to perforate bi- Al's rubber plug the baiaru adapter which possesses the circular array of stuffing the various lengths which engage. Array of stuffing is arranged, the 1st set stuffing of the 1st length which from around the housing of the respective adapter extends inside, and the 1st set stuffing and alternately, has the 2nd set stuffing of each one relatively long length. Set it stuffs 2 and, in order bi- Al where the adapter exceeds specified size when it engages, not to become the disturbance, bias in order to become deformed plastically, it is installed. The housing, at least at the same length as the sharp cannula, being able to stick the medical work person who uses the adapter unexpectedly, in order there are no times when it gets injured, has shiyuroudo which it protects. The needle is not the valve has the deformation possible piston element of the elasticity which possesses the natural open slot. Inside the piston, the fluids style routes which mind the adapter are offered. With one execution example, be able to use for the bi- Al sealing section of diameter approximately 20mm the 1st set stuffing of the adapter, as for the 2nd set stuffing, diameter approximately it can use for the bi- Al sealing section 13 - 17mm.
