Abstract

A processing receptacle for a biopharmaceutical product includes a pocket configured to accommodate the biopharmaceutical product that can assume a flat-folded state, an expanded state, or any intermediate state in between, a processing element having an active inner portion, a rigid protective chamber to protect the processing element, and at least one opening for introducing the product into the receptacle and/or for draining the contents from the receptacle. A portion of the protective chamber is rigidly attached to a portion of the pocket and movement of the pocket up or down brings about movement of the protective chamber; the processing element and the protective chamber are arranged to be independent from one another relative to their movements. The protective chamber has a variable height that automatically adapts to accommodate the flat-folded, expanded, or intermediate state of the pocket, and in each state of the pocket, the processing element is offset from the side walls and the upper end portion of the pocket, while being adjacent to the lower end portion. A device having such a processing receptacle and a method for processing a biopharmaceutical product utilizing such a device are also presented.

First claim

The invention claimed is:

1. A processing receptacle for a biopharmaceutical product, comprising:
a pocket comprising a flexible side wall, a lower end portion and an upper end portion that define a first inner space configured to accommodate the biopharmaceutical product, the pocket being configured to be in a flat-folded state, an expanded state, or in any intermediate state in between, and can be deformed to switch from one state to another;
a processing element for processing the biopharmaceutical product when the product is contained in the first inner space of the pocket, said processing element comprising an active inner portion of a certain height that is arranged inside the receptacle;
a protective means for protecting the processing element, said protective means comprising a side wall, a lower end portion, and an upper end portion that defines a second inner space communicating with the first inner space of the pocket,
wherein the lower end portion of the protective means being adjacent and rigidly attached to the upper end portion of the pocket, a movement of the upper end portion of the pocket upward or downward bringing about a movement of the protective means, whereby the active inner portion of the processing element is arranged in the second inner space of the protective means when the pocket is in the flat-folded state, a peripheral portion of the second inner space of the protective means forming a protective chamber around the pocket and the processing element; and
at least one first opening configured for introducing the biopharmaceutical product into the receptacle and/or for draining the contents from the receptacle,
wherein:
the active inner portion and the processing element are arranged inside the pocket by being adjacent to the lower end portion;
the processing element and the protective means are arranged to be independent from one another relative to their movements;
the protective means has a variable height that can a maximum height, a minimum height, or any intermediate height in between, and can be automatically adapted, based on the state of the pocket that is respectively flat-folded, expanded, or intermediate state;
in each said state of the pocket, the processing element is offset from the side wall and the upper end portion of the pocket, while being adjacent to the lower end portion;
the protective means is rigid and non-deformable;
the protective means is arranged to form a head configured to introduce the biopharmaceutical product into the receptacle; and
wherein the protective means that forms the head comprises at least one second opening configured to introduce the biopharmaceutical product and a removable sealing element for sealing said second opening that is configured to ensure its closing and its opening.

2. The processing receptacle according to claim 1 , wherein the at least one second opening is provided in the upper end portion of the protective means.

3. The processing receptacle according to claim 1 , wherein the removable sealing element is a plug or a membrane.

4. The processing receptacle according to claim 1 , wherein the head comprises a connecting element for removably connecting the receptacle to an aseptic transfer device.

5. The processing receptacle according to claim 1 , wherein the at least one first opening is provided in the pocket.

6. The processing receptacle according to claim 5 , wherein the at least one first opening is provided in the lower end portion of the pocket.

7. The processing receptacle according to claim 1 , wherein the pocket comprises a rigid plate on the lower end portion of the pocket.

8. The processing receptacle according to claim 1 , wherein the protective means, in combination with a protective function of the pocket, the processing element and a guiding function of the pocket, is configured so that when the first opening is open, and the biopharmaceutical product is gradually introduced into the receptacle, the pocket simultaneously expands upward.

9. The processing receptacle according to claim 1 , wherein the processing element and the protective means are structurally dissociated from one another, the processing element and the protective means being separate from and without direct contact with one another, whereby the peripheral portion of the inner space of the protective means around said processing element forms a protective chamber that extends laterally and on top between the processing element and the side wall and the upper end portion of the protective means.

10. The processing receptacle according to claim 1 , wherein the processing element comprises an active portion inside the pocket, which in the flat-folded state of the pocket, occupies the inner space of the protective means.

11. The processing receptacle according to claim 1 , wherein the processing element comprises an active portion inside the pocket, which in the expanded state of the pocket, is essentially integral in the inner space of the pocket, whereby the minimum height of the protective chamber is zero.

12. The processing receptacle according to claim 1 , wherein the processing element comprises:
an active portion inside the pocket, and
optionally with the possibility of relative movement, an inner surface of the lower end portion of the pocket or by a rigid plate that equips the lower end portion of the pocket on the inside.

13. The processing receptacle according to claim 1 , comprising a participating element for holding the processing receptacle in a container, whereby the pocket contains a desired amount of the biopharmaceutical product.

14. The processing receptacle according to claim 13 , wherein the participating element is integrated or connected to the protective means.

15. A device for processing a biopharmaceutical product comprising the processing receptacle according to claim 1 , and a rigid container configured to accommodate the receptacle when the pocket is in the flat-folded, expanded, or intermediate state, to allow the pocket to be deformed in order to switch from one state to another, and to guide the pocket when the pocket expands in volume, said rigid container providing an additional volume when the biopharmaceutical product is introduced into the receptacle.

16. A method for processing a biopharmaceutical product, comprising:
providing a device comprising:
(i) a processing receptacle for the biopharmaceutical product, the receptacle comprising:
a pocket comprising a flexible side wall, a lower end portion and an upper end portion that define a first inner space configured to accommodate the biopharmaceutical product, the pocket being configured to be in a flat-folded state, an expanded state, or in any intermediate state in between, and can be deformed to switch from one state to another;
a processing element for processing the biopharmaceutical product when the product is contained in the first inner space of the pocket, said processing element comprising an active inner portion of a certain height that is arranged inside the receptacle;
a protective means for protecting the processing element, said protective means comprising a side wall, a lower end portion, and an upper end portion that define a second inner space communicating with the first inner space of the pocket,
wherein the lower end portion of the protective means is adjacent and rigidly attached to the upper end portion of the pocket, a movement of the upper end portion of the pocket upward or downward bringing about a movement of the protective means, whereby the active inner portion of the processing element is arranged in t
