Definitions
- cotton bandages Since ancient times wounds have been covered with leaves, skins, cloth and other materials in order to protect the injured area. In modern times cotton bandages have gained universal acceptance. These bandages are in the form of a cloth, gauze, or any other special fabric. While these cotton bandages are of general utility and can be manufactured in sterile condition, they nevertheless are not full satisfactory in all situations. For example, the treatment of the cotton before the weaving thereof may render it less absorbent. Moreover,rthe cotton fabric when placed over a bleeding wound adheres to the clot which forms, and when the bandage is removed it tears the clot and reopens the wound. An additional problem involved with conventional bandages is that they do not adhere well to skin areas which are relatively mobile, such as the chest and abdomen during respiration, or the leg or arm during body movement, even in bed.
- Another object of the present invention is to provide a bandage which is capable of freely moving with the skin which carries the bandage while permitting a wound to heal without the possibility of clinging undesirably to the bandage so that the latter does not interfere with the healing and will not tear the wound when the bandage is removed.
- the objects of the present invention include the provision of a bandage of the above type which can have any desired conguration so that it can be adapted to all parts of the body, which can have practically any size, and which moreover can be manufactured very inexpensively and is at the same time convenient to manipulate and apply.
- the bandage of the invention includes a backing layer made of a fabric, for example, which is stretchable at least in one direction, and this backing layer carries at one of its faces a layer of clot-releasing material which adheres to this one face of the backing layer.
- the outer peripheral edge of the backing layer is situated beyond the outer peripheral edge of the layer of clot-releasing material so as to define with the latter a marginal portion of the backing layer which extends beyond the layer of clot-releasing material, and at least this marginal portion of the backing layer carries a layer of adhesive so that when the layer of adhesive is applied to a wound in a manner surrounding the wound with the clot-releasing material covering the wound, it is possible for the bandage to move with the skin while at the same time permitting free movement of the wound and the sub- ICC jacent skin without the possibility of the clot-releasing material sticking undesirably to the wound.

BANDAGES Filed Sept. 25, 1964 INVENTOR @La/@m7 ATTORNEY United States Patent O 3,288,139 BANDAGES Stanley E. Goodman, 160 East Ave., Westport, Conn. Filed Sept. 23, 1964, Ser. No. 398,581 9 Claims. (Cl. 12S-156) The present invention relates to bandages.
Since ancient times wounds have been covered with leaves, skins, cloth and other materials in order to protect the injured area. In modern times cotton bandages have gained universal acceptance. These bandages are in the form of a cloth, gauze, or any other special fabric. While these cotton bandages are of general utility and can be manufactured in sterile condition, they nevertheless are not full satisfactory in all situations. For example, the treatment of the cotton before the weaving thereof may render it less absorbent. Moreover,rthe cotton fabric when placed over a bleeding wound adheres to the clot which forms, and when the bandage is removed it tears the clot and reopens the wound. An additional problem involved with conventional bandages is that they do not adhere well to skin areas which are relatively mobile, such as the chest and abdomen during respiration, or the leg or arm during body movement, even in bed.
It is accordingly a primary object of the present invention to provide a bandage which will avoid the above drawbacks.
In particular it is an object of the present invention to provide a bandage which will not become embedded in a clot during the formation thereof and which, therefore, will not tear the clot and reopen a wound when the bandage is removed.
Another object of the present invention is to provide a bandage which is capable of freely moving with the skin which carries the bandage while permitting a wound to heal without the possibility of clinging undesirably to the bandage so that the latter does not interfere with the healing and will not tear the wound when the bandage is removed.
Furthermore, it is an object of the present invention to provide a bandage which while it is capable of moving freely with the skin will nevertheless remain reliably attached thereto until it is desired to remove the bandage.
In addition, it is an object of the present invention to provide a bandage of the above type which can be manufactured in sterile condition and which can be maintained sterile until it is applied to the wound.
Furthermore, the objects of the present invention include the provision of a bandage of the above type which can have any desired conguration so that it can be adapted to all parts of the body, which can have practically any size, and which moreover can be manufactured very inexpensively and is at the same time convenient to manipulate and apply.
Primarily the bandage of the invention includes a backing layer made of a fabric, for example, which is stretchable at least in one direction, and this backing layer carries at one of its faces a layer of clot-releasing material which adheres to this one face of the backing layer. The outer peripheral edge of the backing layer is situated beyond the outer peripheral edge of the layer of clot-releasing material so as to define with the latter a marginal portion of the backing layer which extends beyond the layer of clot-releasing material, and at least this marginal portion of the backing layer carries a layer of adhesive so that when the layer of adhesive is applied to a wound in a manner surrounding the wound with the clot-releasing material covering the wound, it is possible for the bandage to move with the skin while at the same time permitting free movement of the wound and the sub- ICC jacent skin without the possibility of the clot-releasing material sticking undesirably to the wound.
The invention is illustrated by way of example in the accompanying drawings which form part of the application and in which:
FIG. 1 is a fragmentary perspective layer of a bandage according to the invention shown in FIG. 1 with a covering layer partly removed so as to illustrate the portions of .the bandage which are covered by the covering layer;
FIG. 2 is a transverse sectional view of the bandage of FIG. 1 taken along line 2 2 of FIG. l in the direction of the arrows and having an enlarged scale as cornpared to FIG. 1;
FIG. 3 is a transverse sectional view of another embodiment of a bandage according to the invention; and
FIG. 4 shows how the bandage lof FIG. 3 appears in a top plan view when the covering layer is removed.
Referring now .to FIG. 1, there is shown therein a bandage 10 having the structure of the present invention, this bandage being of a generally rectangular configuration and having any desired length and width. 'I'he bandage 10 includes a removable cover 12 which may be removed from the remainder of the bandage in the manner indicated in FIG. 1 before the bandage is applied to a Wound. When the covering layer 12 is removed it exposes a layer of clot-releasing material 14, and the layer Iof clot-releasing material 14 is surrounded by a layer of adhesive 16, the layers 14 and 16 both being carried by a backing layer 18 which is at least longitudinally stretchable.
As may be seen from FIG. 2 the backing layer 18 is covered at its top face, as viewed in FIG. 2, by the layer of adhesive 16, and .the layer of adhesive 16 carries the layer of clot-releasing material 1,4 so that the portion of the adhesive 16 which extends beyond the layer 14 can serve to attach the bandage to the skin while the portion of the layer 16 between the layers 14 and 18 serves to attach the layer 14 to the layer 18. The portion of the layer 16 which projects beyond the layer 14 also serves to removably hold the covering layer 12 in position, and after the covering layer 12 is removed the clot-releasing material will be exposed so as to be capable of being applied to a wound with the portion of the layer 16 which projects beyond the layer 14 adhering to the skin and surrounding the wound.
The layer of backing material 18 is preferably a fabric and it is a known fabric which has the property of being stretchable in at least one direction. Thus, this fabric may be Ace fabric as used in Ace bandages, or Elastoplast fabric. The bandages of generally rectangular configuration, as pointed out above, and the backing layer 18 -is preferably arranged in such a way that it is at least longitudinally stretchable.
The layer of clot-releasing material 14 is of the same general configuration as the layer 18, and both lof these layers may be substantially rectangular, although at least the backing layer is preferably provided with rounded corners. The outer peripheral edge of the backing layer 18 is located beyond the outer peripheral edge of the layer of clot-releasing material 14, so that these edges define a marginal portion of that face of the layer 18 which carries the layer 14 extending beyond the outer edge of the layer 14 and at least this marginal port-ion of the backing layer 18 is covered with the adhesive layer 16.
The layer of adhesive 16 is any well known pressure sensitive adhesive which clings to the skin simply by being applied thereto.
The layer of clot-releasing material 14 can have different constructions. Thus, there are known fabrics which have a special thread or a special weave, or both, for im- 3 parting to the fabric the properties which render it clotreleasing. Further, a cloth which is covered or impregnated with a suitable grease will also have this property, and a cloth which -is woven from silic-oned threads will also have the clot-releasing property. Thus, a variety of constructions are available for the layer of clot-releasing material.
The covering layer 12 may be a sheet of polyethylene or polypropylene, or it may simply be `a `covering of crinoline.
Another embodiment of the invention is illustrated in FIG. 3 where the backing layer 1S may be identical with that of FIGS. 1 and 2, and the layer `of clot-releasing material 14 may also be identical with that of FIGS. 1 and 2. Here again the layer of clot-releasing material 14 is of the same general configuration as but smaller than the layer `of backing material 18, and the layer 14 is centrally arranged on the backing layer 18 so as to provide the latter with a marginal portion projecting beyond the layer 14 in the manner described above. With the embodiment of FIG. 3, however, the layer of clot-releasing material clings to the layer of back-ing material 18 either due to the properties of the materials of both lof these layers or with the use of an extremely thin layer of adhesive situated between the layers 14 and 18. In this case, the marginal portion of the backing layer 18 carries a layer of adhesive 16 which may be the same type of pressure-sensitive adhesive as the layer 16, but in this case the thickness of the layer 16 is substantially equal to that of the layer 14 so that the layer of adhesive 16 has an exterior surface which is substantially fiush with the exposed surface of the layer of clot-releasing material 14. With this embodiment the layer of clot-releasing mater-ial 14 is also covered by a layer 12 of a suitable covering material as described above, and this layer 12 may be identical with the layer 12 of FIGS. 1 and 2, although it will lie in a somewhat flatter condition because of the particular construction of FIG. 3 where the layer of adhesive 16 has its exterior surface substantially flush with the exterior surface of the layer 14.
When the covering layer 12 is removed from the bandage of FIG. 3, the bandage may have, for example, the appearance shown in FIG. 4 from which it is apparent that the layer 14 is of the same general configuration as the backing layer and is smaller than but substantially centrally situated with respect to the backing layer so as to expose the layer of adhesive 16 along the marginal portion of the backing layer which extends beyond the layer 14. The structure of FIGS. 1 and 2 will have the same appearance as the structure of FIG. 4 when the covering layer 12 is removed, the 1only difference being that in the case of FIGS. l and 2, the adhesive 16 covers the entire upper face of the layer 18, as viewed in FIG. 1 and as pointed out above.
When the bandage 4of the invention is removed the layer of clot-releasing material will release its position of contact, whether this layer 'of clot-releasing material is in contact with dry skin, and open sore, and oozing wound or a sol-id clot.
All parts of the bandage of the invention are sterilizable.
When the bandage is used the marginal portion thereof which carries the adhesive remains adherent to the skin, while the releasing quality of the clot-releasing mater-ial permits the marginal adherent part of the bandage to move with the subjacent skin while the central part of lthe bandage which has ythe clot-releasing material releases itself from the wound or clot, so that this may also move without any tearing or pulling.
It is to be understood that the term wound is to be applied very generally not only to wounds in lthe form of injuries but also to any contusions and incisions.
Moreover, the bandage of the invention can have any size and configuration to adapt it for a particular purpose. For example, the bandage of the invention has been used after a thoracotomy, and when used for this purpose the layer of clot-releasing material releases and stretches from the long wound. The backing is elastic and stretches also so that there is no resistance to respiratory m-ovements.
The layer of adhesive is of the pressure-sensitive type, as pointed out above, and can be placed on the layer of backing during the manufacture of the bandage, and the backing layer is o-f course cut in such a way that it will have longitudinal elasticity. The entire bandage can be manufactured with known machines in a manner which will not undesirably increase the cost of the bandage while at the same time maintaining all parts yof the bandage sterile.
