Abstract
Abstract A device is disclosed for obtaining fluids containing radioactive constituents particularly suitable for medical purposes. The device includes a holder for a substance having radioactive constituents and which is providing at the upper and lower ends with a portion of a quick-coupling member. In operation a vessel for a flushing liquid is connected with the upper coupling portion and the vessel for the fluid to be collected is connected with the lower coupling member portion to facilitate washing of the holder and collection of the fluid from the holder while avoiding contamination of the fluid in the holder.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
133 words
A device for obtaining fluids containing radioactive constituents particularly suitable for medical purposes comprising a detachable holder closed at its upper and lower end by a pierceable wall, a pair of interfitting box-shaped members surrounding said holder, each of said box-shaped members having a prolongation which is provided with a first part of a quickcoupling means, said first part for each prolongation carrying a hollow needle which protrudes into said pierceable wall during operation of said device, a vessel for containing washing fluid having a second part of said quick-coupling means to be connected with the first part of said quIck-coupling means at the upper side of the holder, and a vessel for the fluid to be collected having a second part of said quick-coupling means at the lower side of the holder.
