Abstract

Claims (42)

1. A glove device with a glove for protected intervention in a work chamber of a containment through an access present in a port flange, wherein:

a) the port flange is installed in a front window or in a wall of a housing of the containment positioned in an installation space; and

b) equipment for processing a material to be treated can be provided in the work chamber, wherein:

c) the glove device is designed as a module, in the form of an insert, which can be inserted gas-tight into the port flange; and comprises:

da) a seal, which is arranged on one side and is removable or is to be opened;

db) on the other side a cover part, which is releasable from the module;

de) the glove vacuum-packed between the two sides, which glove has an inner face and a surface

df) a free end of the glove is fastened to a fixing part and/or to the seal in the vicinity of the fixing part, wherein the seal at least substantially spans the clear width of the fixing part; and

dg) when the cover part is mounted on the glove device and the seal is intact, the seal is visually noticeably curved concavely relative to the glove device as a result of a negative pressure between the cover part and the seal.

2. The glove device as claimed in claim 1 , wherein the glove device also has a fixing part, which is intended to be fastened gas-tight to the port flange.

3. The glove device as claimed in claim 1 , wherein:

a) the fixing part being annular or oval and comprising plastic; and

b) the cover part being shell-like and comprising plastic.

4. The glove device as claimed in claim 1 , wherein when the cover part is mounted on the glove device and the seal is intact:

a) a front space lies between the seal and the surface of the glove, the front space having a negative pressure; and

b) the front space and an inner face of the seal facing said front space and the surface of the glove are sterile.

5. The glove device as claimed in claim 1 , wherein when the cover part is fitted on the glove device and the seal is intact:

a) an interior lies between the inner face of the glove and the cover part or shut-off part, the interior having a negative pressure; and

b) the interior and an inner face of the cover part facing said interior and the inner face of the glove are sterile.

6. The glove device as claimed in claim 1 , wherein an RFID chip is arranged in a fixing part and has, stored therein, an individual serial number and its production data.

7. The glove device as claimed in claim 6 , wherein the RFID chip is writable and all new actions at the glove device, including those at the glove, are captured and added in the RFID chip or in a control unit to individual maintenance data of the glove device.

8. The glove device as claimed in claim 6 , wherein:

c) the production data of each glove device can comprise:

aa) the individual serial number,

ab) a production date;

ac) glove size;

ad) a material type;

ae) a used sterilization method;

af) a maximum use-by date; and

d) maintenance data of each glove device can comprise:

ba) a date of installation in a port flange;

bb) personal data of the installer;

bc) an identifier of the port flange on which the installation was performed;

bd) when, how often and by which operator a shut-off part at the relevant glove device was brought into a blocking position or moved therefrom into an the open position;

be) time and count of number of decontamination cycles at the work chamber of the containment and a maximum permissible number of decontamination cycles;

bf) time and number of leak tests performed on the relevant glove device;

bg) batches and products which are handled in the work chamber of the containment and for which the relevant glove device is used;

bh) special instructions to be input manually by the operator; and

bi) personal data of the installer performing the disassembly and disposal of a relevant glove device.

9. The glove device as claimed in claim 1 , wherein:

a) the cover part has a magnetic zone which is intended for cooperation with a fixing part in order to additionally secure the cover part temporarily; wherein

b) if the cover part is released from the glove device, the magnetic zone can also be used in order to deposit the cover part at a parking station.
