The present invention relates generally to trauma wound dressings intended to stop or substantially reduce bleeding due to laceration or penetrating traumas such as gunshot wounds or stab wounds, and, more particularly, relates to a wound dressing article that is particularly suited to use in junctional injuries that are not suitably addressed by a tourniquet, such as in the groin or armpit. The wound dressing article is a ball-like body having approximately one hemisphere made of, coated with, or comprising a wound dressing material, and a wrap connected to the device body that can be wrapped around the injured person's body and over the wound dressing article to create pressure against the injury location.
Severe laceration, penetrating, or dismemberment injuries to limbs are commonly addressed by use of a tourniquet in order to stop bleeding and prevent death due to blood loss. Junctional injuries are those that occur at the junction of a limb or limbs with the body. The groin and armpit regions, in particular, are junctional locations. When a person suffers an injury at these junctional locations that threatens to result in a critical loss of blood, a standard/traditional tourniquet is unsuitable to address the injury. Such junctional injuries care is instead best addressed by direct pressure and clotting agents. However, it is not practical for a trauma responder to continuously apply pressure to a person's injury until that person can get to more comprehensive trauma care.
Therefore, a need exists to overcome the problems with the prior art as discussed above.
In accordance with some embodiments of the inventive disclosure, there is provided a trauma dressing article for junctional injuries that includes a spherical body having a natural uncompressed spherical shape, and that is made of elastic foam and has an outer surface. There is a gauze cap formed over at least a portion of the outer surface of the body, and it is attached to the body. Further, there is a wrap strip having a first end that is attached to the body and a second end that is free. The wrap strip is configured to wrap around a human and over the body to compress the body.
In accordance with another feature, the body has a diameter of one and a half to three inches.
In accordance with another feature, the body includes a first portion having a first radius and a second portion having a second radius that is smaller than the first radius, and wherein the gauze cap covers the second portion.
In accordance with another feature, the wrap strip is self-adhering.
In accordance with another feature, the wrap strip is elastic.
In accordance with another feature, the wrap strip is provided in a rolled configuration.
In accordance with another feature, the wrap strip is at least four feet long.
In accordance with another feature, the first end of the wrap strip is glued to the body.
In accordance with another feature, the gauze cap contains a clotting agent that is at least one of kaolin, chitosan, or recombinant activated human clotting factors.
In accordance with another feature, the gauze cap includes a dressing tail comprising a free section of dressing material that extends freely from the gauze cap.
In accordance with some embodiments of the inventive disclosure, there is provided a packaged trauma dressing article that includes a body made of elastic foam and that has a semispherical portion that has a rounded outer surface. The trauma dressing article also has a gauze cap disposed on, and covering, the rounded outer surface of the semispherical portion. Further, there is a wrap strip including a sheet strip of dressing wrap having a first end attached to the body and a second end that is a free end. The wrap strip has a length that allows the wrap strip to be wrapped around a junctional location of a person, and further around the person and over the body of the trauma dressing article to compress the body of the trauma dressing article. There is also packaging in which the body, gauze cap, and wrap strip are disposed and sealed to ensure sterility until use.
In accordance with another feature, the packaging is vacuum sealed.
In accordance with another feature, the semispherical portion is a first semispherical portion having a first radius, the body further comprises a second semispherical portion having a second radius that is larger than the first radius, and wherein the gauze cap covers the first semispherical portion.
In accordance with another feature, the wrap strip is provided in a rolled configuration.
In accordance with some embodiments of the inventive disclosure, there is provided a trauma dressing article for use in junctional injuries to prevent exsanguination that includes a body having a sealed gas volume and a flexible exterior wall having an outer surface. There is also an absorbent covering disposed over and attached to the outer surface. Further, the trauma dressing article includes a wrap strip having a first end that is attached to the body or the gauze cap, and which further has a portion that extends from the first end to a free end of the wrap strip. The wrap strip is configured to secure the trauma dressing article to a person by wrapping around the person and over the body of the trauma dressing article and thereby compress the body of the trauma dressing article against the wound site.
In accordance with another feature, the body is spherical and includes a first portion having a first radius and a second portion having a second radius that is smaller than the first radius, and wherein the gauze cap covers the second portion.
In accordance with another feature, the wrap strip and the gauze cap are formed of a contiguous portion of gauze.
In accordance with another feature, the gauze cap contains a clotting agent that is at least one of kaolin, chitosan, or recombinant activated human clotting factors.
In accordance with another feature, the wrap strip is elastic, self-adhering, and configured in a roll.

It is to be understood that the disclosed embodiments are merely exemplary of the invention, which can be embodied in various forms.
The trauma dressing article 100 includes a body 102 that can include a first portion 104 and a second portion 106. A gauze cap 110 is affixed to the to body 102 and covers at least a portion of the body 102. In some embodiments the gauze cap 110 can cover about half of the body 102, although in some other embodiments the entire body 102 can be covered by gauze or a gauze cap 110. The gauze cap 110 can include more than, for example, a single layer of gauze placed on the body. When actual gauze is used, there should be several layers, as would be used in a gauze pad designed to be applied to bleeding wounds. As is well known, medical gauze is a woven fabric made typically made of cotton. Those skilled in the art will appreciate that other medically suitable absorbent materials can be used equivalently. Thus, as used here, the term “gauze cap” will be understood to refer to a medically suitable absorbent covering of the body 102.
The portion of the body 102 on which the gauze cap 110 is affixed can have a rounded outer surface and is preferably compressible such that when the body is urged/pressed against a wound site that portion of the body 102 will deform somewhat to the contours of the body and the wound site.
The gauze cap 110 is made of a hemostatic gauze which may contain substances such as kaolin, chitosan, or recombinant activated human clotting factors. It may also be made simply of an absorbent material that is suitable for application to a bleeding wound. The gauze cap 110 can be formed, for example, by feeding a strip of gauze into a mold, which has the negative shape of the portion of the body 102 to which the gauze cap will be attached, and then a medically suitable adhesive can be used to join the gauze cap to the body 102, providing several layers of gauze between the outside of the gauze cap 110 and the surface of the body 102 on which the gauze cap 110 is disposed. In another embodiment the gauze cap can be formed by layering sheets of gauze, placing the layered gauze over the body 102, and then cutting off excess gauze. In another embodiment, a roll of gauze can be formed having an inside diameter (or shape) that is equal the diameter (or shape) of the body 102, and the body 102 can be inserted into the gauze roll such that one end of the gauze roll can be adhered or affixed to the body, and the opposite end can be folded over and against the body, and glued or stapled in place. In an alternative form of connecting the gauze to the body 102, the body 102 can have cuts into the body 102 into which portions of the gauze cap 110 can be inserted. The resiliency of the material of the body 102 will hold those portions (or portion) by friction and retain them and the gauze cap 110 to the body. In addition to the gauze cap 110 there is a wrap strip 112 that has an end 114 which is attached to the body 102, such as by a medically suitable adhesive, or by a mechanical connection (e.g. fasteners, or being inserted into a portion of the body for frictional retention).
The wrap strip 112 is a strip of dressing wrap material that is wrapped around the patient's body after the gauze cap 110 is placed against the wound site. The dressing wrap material of the wrap strip 112 is therefore a sheet strip of pliant material like a fabric that can be initially gathered in a rolled configuration or equivalent gathering/bunching/folding configuration that allows a person to wrap the wrap strip 112 around the patient's body, and over the body 102 of the trauma dressing article 100 in order to put pressure on the body 102, and therefore against the wound site. The wrap strip 112 therefore has one end attached to the body 112, and another end 115 that is free (free end) and not attached to anything. In some embodiments the wrap strip 112 can be elastic to allow it to be stretched, thereby creating pressure against the body 102 as the material of the wrap strip 112 tends to elastically contract towards its original state upon being stretched. In some embodiments the wrap strip can be self-adhesive, so that, upon the distal end of the wrap strip 112 being exposed after wrapping the entire length of the wrap strip 112 around the patient's body (several times), the material of the wrap strip 112 will tend to stay in place due to the adhesiveness of the material between portions of the wrapped material in contact with each other, and the end can be tucked into the wrap or tied to the wrap, as is appropriate for a given injury treatment and patient. In some embodiments the wrap strip 112 can be at least four feet long from the first end 114 to the free end 115 of the wrap strip 112. In other embodiments the wrap strip 112 can have other lengths.
The gauze cap 110 generally conforms to the shape of the body 102. As shown there, the body can be spherical, or ball-shaped. In some embodiments the body 102 can be a generally spherical shape having a diameter of one and a half to three inches. This range is particularly suitable for armpit and groin injuries such as gunshot and stab wounds. In other embodiments the spherical body can be larger or smaller. The body 102 can be made of a resilient material, or be compressible with a tendency to return to its uncompressed state. Thus, the body 102 can be made of an elastic foam, or it can have a sealed gas (e.g. air) volume and a flexible exterior wall. By being resilient in this manner, when the body 102 is under pressure from the wrap strip 112, the body 102 can deform from its natural uncompressed state to conform to the body region where it is applied on the patient. That is, the portion of the body 102 facing the wound site (e.g. the gauze cap 110 side) will flatten or otherwise match the shape of the body portion it is pressed against. Of course, this pressure also acts to shape the skin and soft tissue, but any hard body portions (e.g. bones) cause the body 102 to conform around those hard body portions and still maintain pressure on the wound site. The seal of the wound site can also be improved in some embodiments by the inclusion of a clotting agent in the gauze cap 110. For example, chitosan and kaolin are known clotting agents that can be impregnated in the gauze cap 110 material.
The body 102 can be formed in a variety of shapes to conform to the shape of the various junctional body regions. However, a compressible, resilient, and generally spherical shaped body has good all-around application. The body 102 specifically shown in
A trauma dressing article has been disclosed that is particularly suited to prevent exsanguination due to junctional injuries. The disclosed trauma dressing article includes a body having a gauze cap and a wrap strip attached to the body. The gauze cap is placed into the wound site and the wrap strip is used to create windings around the injured person's body and the body of the trauma dressing article, creating pressure against the body of the trauma dressing article into the wound site.
The claims appended hereto are meant to cover all modifications and changes within the scope and spirit of the present invention.
This application is a continuation of U.S. patent application Ser. No. 17/971,111, filed Oct. 21, 2022, the entirety of which is hereby incorporated by reference.
