Description of the Accomplishments

As shown in Figs. 1 to 3, a liquid resistant protection may be formed by sealing one end of a plastic sleeve in order to form a bag 1 having an open end 2a and a closed end 2b. Unless otherwise specified, sleeve 1 will later be referred to as a bag 1.

Fig. 1 shows a liquid resistant protection, comprising an elongated sleeve-like bag 1 of a water-resistant polymer film. The polymer film may be composed of a thin olefin plastic, such as ethylene plastic, propylene plastic or the like, or compounds thereof. The polymer film may further comprise additives such as ethylene butyl acrylate (EBA) in order to make the polymer film softer, more flexible and firmer. Other polymeric materials and additives known to those skilled in the art, which are suitable for forming the water-proof polymer film and which can be used in contact with the skin can also be used. The bag 1 has an open end 2a through which a limb can be inserted, such as a part of an arm, a leg or a foot. An adhesive layer 3 is arranged in a section 3 outside the bag adjacent to the open end. In the embodiment shown, section 3 with the adhesive layer 3 basically moves over half the circumference of the bag. The adhesive layer 3 may be covered with a protective film that maintains the liquid resistant protection. This protective film 4 may be designed so that it can easily be separated from the adhesive layer.

3.

Fig. 2 shows a liquid resistant protection comprising a bag similar to the embodiment of the bag 1 shown in Fig. 1. The protection according to Fig. 2 further comprises an elongated sealing strip 5 which likewise that the bag may be composed of an olefin plastic. A surface 6 of the sealing strip 5 may have an adhesive layer 6. The adhesive layer 6 may also be covered with a protective film 7 that maintains the liquid resistant protection. This protective film 7 can be easily separated from the adhesive layer 6. The sealing strip 5 can be integrated with the bag 1 or separated and packaged in a part assembly together with the bag 1.

Fig. 3 shows a variant of the bag 1 shown in Fig. 2. The bag 1 shown in Fig. 3 differs from that shown in Fig. 2 in that one end of the sealing strip 5 is attached to the bag adjacent to open end 2a. The sealing strip 5 may be attached to the bag 1 by means of adhesive, for example, or by welding. Other forms of fastening known to those skilled in the art, such as a sealing strip 5, can also be used.

Fig. 4a-4b illustrates how the bag 1 shown in Fig. 1 is applied to a forearm 8. As can be seen in Fig. 4a, a forearm 8 has been inserted through the open end 2a. The open end 2a of the bag 1 is then tightened around the forearm 8, so that the excess material forms a flap 9. A part of one side 10 of the flap comprises a part of the entire section having the adhesive layer 3. The protective film 4 is then removed and the flap 9 is folded so that the adhesive layer 3 is attached to the outside of the bag adjacent to the open end 2a and flat against the skin (Fig. 4b). This method provides an easy way of putting on liquid-resistant protection and at the same time good protection against moisture, especially if contact between the two sections of the adhesive layer is achieved, counteracting the formation of a conduit through the fold.

Fig. 5a-5b illustrates how a sealing strip 5 can be applied in order to further improve the protection against moisture. The bag 1 is first applied as described above in relation to Fig. 4a-4b. The protective film 7 is then separated from the sealing strip 5, which in turn is attached to the outside of the bag 1 and applied in Fig. 4b adjacent to the open end 2a. The sealing strip 5 is then wound around the arm 8 so that it finally covers an area comprising a part of the section of the bag 1 at the open end 2a, which closes the limb and the skin bordering this section.

As shown in Fig. 6, the liquid resistant protection may further comprise a relief valve

11. This relief valve 11 allows a limb, which has been provided with a liquid resistant protection that surrounds a wound, for example, to be fully submerged in water. Without this relief valve 11 the water pressure would force the air included in the bag 1a to exit through the sealed opening 2a of the bag, which could lead to the destruction of the tight seal at the open end 2a of the bag 1. The relief valve 11 is suitably disposed in a section of the bag 1 adjacent to the open end 2a of the bag 1, since the end provided with the liquid resistant protection is suitably submerged with a part of the tip closed by the closed end 2a of the bag 1 which is submerged first, followed by the part of the end enclosed by the open end 2a. The relief valve 11 may be attached to the bag 1 before or after applying the liquid resistant protection to a limb as described.

E05819794 11-22-2011

previously. An example of a relief valve 11 is a non-return valve that allows the air included in the bag 1 to flow outside and that prevents liquids from entering inside the bag 1. The construction of such a non-return valve 11 It will be familiar to those skilled in the art and may comprise a valve body 12 having a through passage 13 in which, for example, a diaphragm, such as a rubber diaphragm, is designated to perform the function of the non-return valve . The valve body 12 may further comprise a plate 14 through which the conduit 13 travels in a direction at a right angle to the plane of the plate 14. This plate 14 allows the valve to be fixed to the bag 1. For example , an adhesive layer may be arranged on a surface of the plate 14 to be fixed to the bag 1. The relief valve 11 may also be designed with polymer film penetration means of the bag 1 and produce an opening on which the relief valve 11 can be fixed (not shown). In the absence of such means, the opening can be achieved by other means such as a pen.

According to one embodiment, the relief valve 11 may comprise an open duct 13 without a non-return valve function. In this embodiment, the conduit 13 can be sealed, for example, by means of a tape once the air has been forced out and before the section with the relief valve 11 is submerged in water.

According to one embodiment, the adhesive layer 3 of the bag 1 may comprise a double-sided adhesive tape. It will be appreciated that other types of adhesive layer 4 can also be used, such as an adhesive layer applied to the bag 1. It will also be appreciated that in several embodiments, the section having the adhesive layer 3 can cover a greater or lesser portion of the circumference and length of the bag 1. The adhesive layer 3 must comprise a part of the outer surface of the bag large enough to form a tight fold.

According to one embodiment, the shape of the bag 1 is optional and can be adjusted to the contour of the limb to be protected from the liquid. An example of an optional form of the bag 1 is a sock-shaped bag, which is intended for the liquid-resistant protection of a foot.

According to one embodiment, the sealing strip 5 is at least equal in length to the circumference of the end around which the sealing strip 5 is to be wound. This length allows a secure seal of the bag 1 around the limb, which provides a liquid resistant protection that remains tight, especially during bathing, when the limb is fully submerged in water.

A liquid resistant protection is also provided comprising a sleeve 1 of a waterproof polymer film, the sleeve 1 having two open ends 2a. An adhesive layer 3 for sealing the sleeve 1 is arranged in a section 3 on the outside of the sleeve 1 adjacent to each of the open ends 2a. It will be appreciated that this embodiment may also comprise two sealing strips 5. Such sleeve 1 having two open ends, may be suitable for liquid-resistant protection of the inner part of one limb, such as an upper part of the arm. The embodiment comprising a bag 1 having an open end 2a and a closed end 2b may be suitable for liquid resistant protection of an outer part of a limb, such as a hand or foot. Sleeve 1 may thus be adapted to cover only the necessary part of the limb.
