Method and device for manipulating and transferring products between confined volumes

A device for transferring fluids through a surface, the device comprising:

• a piercing means for piercing the surface, said piercing means having a first end and a second end which is insertable into the surface;
• a flexible tubular film having a first end surrounding said second end of said piercing means and extending away and gradually widening outward from said piercing means to form a flanged second end;
• a diaphragm adhesivable to the surface, said diaphragm extending across and sealing said flanged second end of said flexible tubular film, said piercing means being movable and pierceable through said adhesivable diaphragm and the surface when said adhesivable diaphragm is in contact with the surface, said piercing means also being removable from the surface, and said adhesivable diaphragm being removable from said surface after said piercing element is removed from said surface and said adhesivable diaphragm;
• an elastic hood-type sheath surrounding and sealing off said piercing means from an outside environment, said hood type sheath having a first end adjacent said first end of said piercing means, and a second end adjacent said second end of said piercing means and connected to said first end of said flexible tubular film, said piercing means being movable inside and pierceable through said elastic hood-type sheath;
• and
• a protection ring located inside said elastic hood-type sheath through which said piercing means is able to slide and pierce said elastic hood-type sheath, said first end of said flexible film surrounding a portion of said elastic hood-type sheath through which said piercing means pierces.
