Definitions
- the present invention relates to the packaging of sterilization baskets and more particularly to a machine for the automated or semi-automated packaging of a sterilization basket and a related packaging method.
- pouches can be of several types: pouches, pouches, sachets, sheaths, envelopes, containers or sterilization sheets.
- Packaging that is in the form of sachets or envelopes are limited in capacity and do not allow to receive bulky and / or heavy objects.
- sterilization sheets are commonly used in sterilization centers.
- the sterilization sheets are particularly suitable for packaging bulky and / or heavy objects such as sterilization baskets.
- a first technique commonly used in medical settings for packaging sterilization baskets with sterilization sheets is the so-called "Pasteur folding" technique. According to this technique, a sterilization sheet is folded repeatedly so as to obtain sufficient tortuosity to maintain the sterility of the contents of the package, without any sealing being performed.
- the quality of the folding depends on the maintenance of sterility.
- the folding operation is then performed sequentially, in two steps, firstly using a first sterilization sheet still called primary or internal packaging, then a second sterilization sheet still called secondary packaging. or outside.
- the primary packaging which has an individual protective role of sterility, constitutes a barrier impermeable to micro-organisms around the sterilization basket.
- the secondary packaging which surrounds the primary packaging, is designed to protect the primary packaging and its contents to the point of use. The secondary packaging avoids any damage that may occur to the primary packaging and its contents, especially during handling, transport or storage operations.
- This double packaging system combining microbiological protection by the primary packaging and mechanical protection by the secondary packaging, improves the maintenance of sterility.
- it requires a sequential folding operation, which has the disadvantage of extending the time of the folding operation performed by the operator.
- EP 0 707 460 A1 and EP 1 362 557 A1 teach the possibility of wrapping the sterilization baskets in a double package, the folding operation being carried out in a single step, which offers a gain in terms of time and simplicity of implementation of the folding operation.
- the sterilization package is then made of two sterilization sheets attached to each other on the edges so as to be held together.
- the edges of the sterilization sheets can be joined to one another, in particular by adhesives, a sting, a thermal or ultrasonic bond.
- the sterilization package consists of two polypropylene sterilization sheets of SMS structure (Spunbond-Meltblown-Spunbond) which are heat-sealed to each other at the edges.
- a second technique is to put the object to be sterilized in a peelable package. Once the object is in the package, the package is sealed and then subjected to the sterilization step.
- the packages are usually made of two separate sheets made of different materials. One of the leaves is most often transparent.
- the packaging is adapted to the sterilization technique used. This technique has the advantage of not requiring a folding operation which saves time.
- the peelable packages consist of two heat-sealed sheets, the mechanical strength can be limited by the mechanical strength of the weld which ensures the junction between the two sheets, or by the strength of the package itself. This technique is therefore not a first choice for packaging bulky and / or heavy sterilization baskets.
- the invention aims to further improve the devices and methods used to package sterilization baskets, and in particular to overcome all or part of the above disadvantages. It achieves this through a machine for packaging with at least one sterilization packaging material, in particular a sterilization sheet, an object, in particular a sterilization basket, comprising:
- a tray for receiving the sterilization packaging material and the object to be packaged on it
- the machine according to the invention allows the packaging by at least one sterilization packaging material of an object that may contain medical devices, including reusable, freshly washed and disinfected. These medical devices may be elements intended to be in contact with the human body and / or used in operating theaters, such as surgical gowns and / or surgical instruments, in particular scalpels, pliers, scissors, endoscopes, basins, trays or tongue depressors.
- the machine according to the invention can be used in sterilization centers, in particular hospitals and health establishments, and / or by manufacturers of surgical packs.
- the machine according to the invention can be used to package an object, such as a sterilization basket, whether it is a standardized basket such as a basket complying with the ISO 3394 standard or the DIN 58952 standard, or a non-standard basket. standardized.
- the machine according to the invention allows automation of the folding operation, which generates on the one hand a reduction in the cost of production of a sterilization basket, in particular by transferring a part of the available labor on the machine. other tasks.
- Another advantage is that, in terms of productivity, the automated folding operation performed by the machine according to the invention is at least as fast as a manual folding operation performed by a human operator.
- Standardization packaging material means any packaging material intended for sterilization, that is to say any packaging material which is compatible with a sterilization process, in particular with EtO gas and / or by steam and / or dry heat and / or low temperature formaldehyde vapor (LTFS process) and / or any other oxidative or non-oxidative sterilization process, while providing the bacterial barrier required to maintain sterility for the duration of claimed life for the packed object.
- LTFS process low temperature formaldehyde vapor
- the sterilization packaging material is for example a sterilization sheet and must then meet the general requirements described in the international standard ISO 11607-1: 2006 / Al: 2014: "Packaging for terminally sterilized medical devices - Part 1: Requirements for materials, sterile barrier systems and packaging systems "defining, in particular, microbial barrier properties and compatibility with the sterilization process.
- the performances of the sterilization sheets are also described in the European standard EN 868-2: 2017: “Packaging materials and systems for sterilized medical devices at the end-stage - Part 2: sterilization envelope - Requirements and test methods" .
- the sterilization packaging material may also be a sterile field in accordance with ISO 13795 and / or AAMI PB 70.

- the table accommodates these corners of the sterilization packaging material.
- the table has at least one truncated corner.
- the corner of the sterilization packaging material that is in this truncated corner does not rest on the table, but extends cantilevered beyond this truncated corner, which facilitates the accessibility of the trunk. tray to operators, when the introduction and removal of the object are not automated, or any conveyor system and / or adapted automaton.
- the machine may comprise at least one holding and / or folding tool, the holding and / or folding tool and the plate being able to move relative to each other, the holding tool and / or bending being arranged to intervene on the sterilization packaging material while at least one ply has been formed along one side of the object, by plating with the aid of at least one plating member the sterilization packaging material on at least one adjacent side of the object, near the side along which the fold has been formed and around which the next fold is to be made.
- Such a holding tool and / or folding facilitates the realization of the other three folds after the first, ensuring that the previously formed fold is brought inward and pressed against the object at the time of the formation of the next.
- the holding and / or folding tool comprises a push member, movable inwardly to push inward a portion of the sterilization packaging material extending along the already formed fold, look at the portion of the sterilization packaging material already pressed against the object.
- the plating member may be in the form of a vertical fixed plate, and the thrust member in the form of a vertical plate, movable about a horizontal axis of rotation, preferably between a raised position and a lowered position where it is superimposed at least partially with the fixed plate.
- the holding and / or folding tool in particular with its plating member and / or its thrust, solves the problems of using shape memory sterilization packaging materials, such as cellulose-based sterilization packaging materials, including creped paper, reinforced paper and / or non-paper. woven cellulosic.
- the machine comprises at least two clamps for grasping at least a portion of the package between them and lifting it, so as to push a corner of the sterilization packaging material under the portion or portions thus raised .
- This or these packaging portions may be formed of one or more thicknesses of the sterilization packaging material, which are to cover the object due to the previous folding operations.
- the two clamps can be mounted so as to be able to deviate from one another and stretch the seized portions or portions. This facilitates the engagement of a portion of the sterilization packaging material under the portion or portions thus stretched and raised.
- the clamps are pivotally mounted on the holding tool and / or folding.
- the machine comprises an object holding system comprising at least two movable lateral holding members, between which the object can be held laterally.
