Description

ABAG

Field of the Invention -

The present invention relates to a bag, more particularly a bag for medical equipment, typically although not exclusively.

Background

Use of scopes in medical procedures are increasing as increasing technical progress improves their qualities.

For example endoscopes, boroscopes and the like are common in many gastrointestinal, plastic surgery, urinary procedures or during pregnancy.

Particularly in smaller medical communities, said scopes can serve many surgeons, and many patients. Standards of hygiene must be maintained.

Guidelines are consequently published by relevant medical bodies such as in the United Kingdom the BSG (British Society of Gastroenterology) that state that when endoscopes have to be transported between a clean room to any other destination they have to be sealed to avoid any cross contamination.

Summary of the Invention

Bag for Endoscopes According to the present invention there is provided a bag for medical equipment, said bag having in use two faces clean(Fig 1) and contaminated (Fig 2) including a large transparent window (5 Fig 1) (3 Fig 2) for visual content clarification, comprising a sterile inner and an outer, sealed along three sides and characterised in that integrated means for sealing the fourth side are made available when either the green (clean) side or red (contaminated) are uppermost (2 Fig 1) (3 Fig 1) in this way the scope bag may be used to cover a scope when in a first disposal a first face is the inner face and consequently the scope is in contact with the first face (Fig 1).

Secondly the second face (Fig 2) may be the inner lace after a user turns over the bag, and subsequently the second face is in contact with the scope, and the first face is no longer in contact with the scope.

In this way transfer of matter or cross-contamination is prevented, minimised or reduced. The user is able thereby to provide a sterile environment in which to store or transport the scope to a location or procedure room, and after use or the procedure can put the scope into a clean self-contained environment.

In all preferred embodiments the bag is formed of a single rectangular piece of plastics material or medical plastic film, heat sealed along three sides.

According to a second aspect of the present invention the means is comprised of a plurality, typically two, seals (2 Fig 1)(3 Fig 1).

Said bag material is preferably medical grade and ideally glossy or smooth finished in order to minimise attraction and collection of bacteria or matter in use.

The inner face as supplied will be sterile, for example wherein the bag is produced in a sterile environment and provided in a sealed container.

in preferred embodiments the seal or at least one seal for the bag may be comprised by or formed in use with a self adhesive strip, wherein the strip is provided before use with a cover, wherein said cover prevents adhesion or loss of adhesive properties.

In other embodiments the seal may be adhered to the bag before use, and may be detached from the bag to effect a closure when in use.

in preferred embodiments at least one of the strips is provided on a flap of material, wherein said flap is sealed or connected to a face on one side alone for the flap.

In other embodiments two flaps are provided, wherein the flaps are opposite each other or more particularly the faces are not sealed along a portion of the sides adjoining the unsealed or sealable side.

The user would therefore remove a cover before use and thereby expose the strip, subsequently placing said strip onto an opposing area of the opposing face, simultaneously encompassing or encircling the scope or part of it.

For example, therefore after use of the scope the user would subsequently turnover the bag and remove the second cover to use the second strip and close the second flap over the opposing face.

Other embodiments may include additional or alternative means of closure, said means including such as drawstrings. Further embodiments may include press studs, or press seals composed of male and female corresponding sections.

According to a third aspect of the present invention a printed or block colour graphic (4 Fig 1) (2 Fig 2) is provided on at least one face of the bag, in order that the user may easily recognise the face in use, and so further reduce danger of cross-contamination.

The invention has been described by way of examples only and it will be appreciated that variation may be made to the above-mentioned embodiments without departing from the scope of invention.

With respect to the above description then, it is to be realised that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.

Brief Description of Ficiures

Figure 1 shows a sketch of a bag showing the clean side image according to the present invention. And

Figure 2 shows a sketch of a bag showing the contaminated side image according to the present invention.

Detailed Description of Figures

The pictured and preferred embodiment helps facilitate mobility of endoscopes or other medical scopes between procedure rooms and clean rooms in endoscopy units.

As the bags come sterile packed it also helps deliver a scope into a clean environment.

The seals (2 Fig 1) (3 Fig 1) in the pictured and preferred embodiment are removed from the back and subsequently used freely to seal the bag around something.

In use therefore a user would place an endoscope into the bag then sealing the flap (1 Fig 1) (1 Fig 2) with the self-adhesive seal (2 Fig 1) (3 Fig 1) so the scope is now enclosed in the bag, ready to be taken into a procedure room.

Now the endoscope has been sealed in the bag, the user can see through the large transparent window (5 Fig 1) (3 Fig 2) that the correct items have been selected for the procedure.

Once in the procedure room a nurse, assistant or the user then undoes a first seal (2 fig 1) and takes the scope out to be used on a patient.

During the procedure, after the procedure or in the meantime the bag is turned over to be ready to be used again.

B

Preferred embodiments will feature a block colour graphic (3 Fig 1) (3 Fig 2) on the faces of the bag, said graphics being easily understood to indicate that the bag is either clean (green) or contaminated (red) (3 Fig 1) (3 Fig 2).

Once the scope has been used and is ready for cleaning the scope is then placed back inside the bag and sealed again with the closing flap/lid (1 Fig 1) with the remaining seal (3 Fig 1) to be taken to the clean room for cleaning.

This process is then repeated for the next scope with a clean bag.
