DESCRIPTION:
BRIEF SUMMARY
The present invention relates to an improved barrier means particularly envisaged for use in inhibiting the passage of liquid into an area. For example, the improved barrier means may typically be used to protect of parts of a persons body, such as parts of a persons body covered with a dressing, from becoming wet when showing or bathing. Also, the improved barrier means may be used on machinery having flexible bodies and the like requiring substantially liquid proofing for the flexible bodies or parts thereof.
FIELD OF THE INVENTION
Generally, when a person having medical dressings on parts of his/her body is to shower or bath, a substantially water impervious covering layer, such as of plastics materials, is placed over such dressings and attached to the body by sticking plasters. Usually, expensive hypo-allegenic sticking plasters. To attempt to obtain a substantially water (or liquid) proof covering several layers of sticking plaster are used.
It has been found that such arrangement tends to leak by becoming unstuck at places where the body bends. Also, the multiple layers do not intend to all be attached with the same tension and passage ways are created between the sticking plaster and the body and/or between layers of the sticking plaster.
If such covering layers do leak and the dressing becomes wet the dressing must be replaced so as not to inhibit healing of a wound covered by the dressing and/or to inhibit the spread of water born infection.
Such sticking plasters tend to be aggressive in sticking to the skin of a person and can disturb the healing of the wound during removal of the covering layer.
Also, it is difficult to commence removing the covering layer due to the nature of its adhesion to the person's body.
We have discovered that the problem with the previous technique of covering dressings as described above, is that the sticking plaster is virtually inelastic. So while the skin of the person is liable to bend and stretch with movement, the prior art covering layers are prone to not so bending and stretching at their attachment to the body due to the limitation of the sticking plasters used.
SUMMARY OF THE INVENTION
The present invention provides an improved barrier means which seeks to overcome the above mentioned problems. In accordance with one aspect of the present invention there is provided an improved non-reusable barrier means for a body part characterized in that it comprises a covering made from a substantially liquid impervious flexible material, the covering being in the form of either a bag with an open end or a tube with two or more open ends, and a liquid impervious strip either attached to or integral with a periphery of the or each open end such that the strip traverses the entire periphery for sealing the periphery to the body part, the strip having an adhesive backing which is non-agressive and liquid impervious, the strip being relatively flexible and elastically extendable, the adhesive backing being disposed inwardly with respect to the periphery, a crease formable by manipulation of the strip, and an adhesive edge formable by sticking the adhesive backing onto itself from the crease toward the body part such that there is little or no mutual contact of the adhesive backing at the body part, the adhesive edge being disposable for sticking to an outside of the covering adjacent the periphery to finalise sealing of the or each open end to the body part and the adhesive edge extending along less than half the length of the periphery.
In accordance with another aspect of the present invention there is provided an improved non-reusable barrier means for a body part, characterised in that it comprises a layer made from a substantially liquid impervious flexible material, the layer being either relatively flat or slightly raised, and a liquid impervious strip either attached to or integral with a periphery of the layer such that the strip traverses the entire periphery for sealing the periphery to the body part, the strip having an adhesive backing which is non-aggre
