Abstract
An automated process for filling a sealed receptacle (1) with a fluid under aseptic conditions is disclosed. The sealed receptacle has at least one part (2B) made of a material capable of being pierced by a hollow needle (8R) and sufficiently flexible to close itself up again after removal of the hollow needle. In the automated process, the part (2B) of the sealed receptacle is pierced using a hollow filling needle (8R) which is in contact with the fluid to be channeled into the receptacle (1). During the process of filling the receptacle (1), the perforating end of the hollow filling needle (8R) is maintained under aseptic conditions by means of laminar gas flow.
Claims13
An automated process for filling a sealed receptacle (1) with a fluid under aseptic conditions, wherein said receptacle is a bag and has at least one part (2B) made of a material capable of being pierced by a hollow needle (8R) actuated by a motorized means and sufficiently flexible to close itself up after removal of the hollow needle, comprising the steps of:
- piercing said part (2B) with a perforating end of a hollow filling needle (8R) which is connected to the fluid and actuated in a direction of the receptacle by the motorized means;
- filling the receptacle (1) with fluid;
- and maintaining the perforating end of the hollow filling needle (8R) under aseptic conditions using a laminar flow (7) during the process.
An automated process for filling a sealed receptacle (1), with a fluid under aseptic conditions, wherein said receptacle has at least one part (2B) made of a material capable of being pierced by a hollow needle (8R) actuated by a motorized means and sufficiently flexible to close itself up after removal of the hollow needle, comprising the steps of:
- piercing said part (2B) with a perforating end of a hollow filling needle (8R) which is connected to the fluid and actuated in a direction of the receptacle by the motorized means;
- filling the receptacle (1) with fluid;
- and maintaining the perforating end of the hollow filling needle (8R) under aseptic conditions using a laminar flow (7) during the process, wherein the sealed receptacle contains, before filling, another fluid and wherein said part is pierced using a hollow evacuation needle (8E).
An automated process for filling a sealed receptacle (1) with a fluid under aseptic conditions, wherein said receptacle has at least one part (2B) made of a material capable of being pierced by a hollow needle (8R) and sufficiently flexible to close itself up after removal of the hollow needle comprising the steps of:
- piercing said part (2B) with a perforating end of a hollow filling needle (8R) which is connected to the fluid;
- filling the receptacle (1) with fluid;
- and maintaining the perforating end of the hollow filling needle (8R) under aseptic conditions using a laminar flow (7) during the process;
- wherein the sealed receptacle contains, before filling, another fluid end wherein said part is pierced using a hollow evacuation needle (8E), and wherein the hollow evacuation needle (8E) is connected to an evacuation device.
An automated process for filling a sealed receptacle (1) with a fluid under aseptic conditions, wherein said receptacle has at least one part (2B) made of a material capable of being pierced by a hollow needle (8R) and sufficiently flexible to close itself up after removal of the hollow needle, comprising the steps of;
- piercing said part (2B) with a perforating end of a hollow filling needle (8R) which is connected to the fluid:
- filling the receptacle (1) with fluid;
- and maintaining the perforating end of the hollow filling needle (8R) under aseptic conditions using a laminar flow (7) during the process;
- wherein the sealed receptacle is substantially evacuated of gas before filling.
An automated process for filling a sealed receptacle (1) with a fluid under aseptic conditions, wherein said receptacle has at least one part (2B) made of a material capable of being pierced by a hollow needle (8R) sufficiently flexible to close itself up after removal of the hollow needle, comprising the steps of:
- piercing said part (2B) with a perforating end of a hollow filling needle (8R) which is connected to the fluid;
- filling the receptacle (1) with fluid;
- maintaining the perforating end of the hollow filling needle (8R) under aseptic conditions using a laminar flow (7) during the process;
- and completing the closure at the site (2A, 2B) perforated by the hollow needle (8R, 8E);
- wherein the closure is completed by hot sealing or by using a laser beam.
An apparatus for filling a sealed receptacle under aseptic conditions comprising:
- a motorized hollow filling needle (8R) having a perforating end, a generator of a laminar gas flow (7) active over at least the perforating end of a filling needle (8R), a retention means (6) for retaining a receptacle (1) to be filled with a fluid during filling, motorized means for actuating the hollow filling needle (8R) in the direction of the receptacle (1) for perforating the receptacle, and a supply of filling fluid in fluid communication with the hollow filling needle (8R).
An apparatus for filling a sealed receptacle under aseptic conditions comprising:
- a motorized hollow filling needle (8R) having a perforating end, a generator of a laminar gas flow (7) active over at least the perforating end of a filling needle (8R), a retention means (6) for retaining a receptacle (1) to be filled with a fluid during filling, motorized means for actuating the hollow filling needle (8R) in the direction of the receptacle (1) for perforating the receptacle at a first location, a supply of filling fluid in fluid communication with the hollow filling needle (8R), and a motorized hollow evacuation needle (8E) whose movements are synchronized with those of the motorized hollow filling needle (8R) to pierce said receptacle at a second location remote from said first location.
