PRESSURE APPLYING DRESSING
A dressing for applying pressure to a patient target site is provided. The dressing includes an elastic spacer longitudinally extending between first and second substrates. The elastic spacer is configured to be selectively moved between the first length and a second length. The second length is longer than the first length. A triggering element, when present, selectively maintains the elastic spacer at the second length and selectively prevents the elastic spacer from moving toward the first length. Portions of the triggering element are sequentially removable such that as each portion of the triggering element is removed, the elastic spacer sequentially moves from the second length toward the first length. The sequential movement of the elastic spacer from the second length toward the first length responsively urges the first and second substrates longitudinally toward one another to apply a predetermined amount of longitudinal force to the patient target site.
This application claims priority from U.S. Provisional Application No. 62/696,083, filed 10 Jul. 2018, the subject matter of which is incorporated herein by reference in its entirety.
TECHNICAL FIELDThis disclosure relates to an apparatus and method for use of a dressing for applying pressure to a patient target site.
BACKGROUNDIn certain situations, dressings are used to apply a predetermined amount of pressure to a patient's skin, to a wound, to close a wound, to keep a wound closed, to remove tension from a wound, to redistribute tension away from a wound, to evert a wound, and/or for any other purpose. In some situations, it might be desirable to increase the amount of pressure or force provided by a dressing over time without having to apply a new dressing. It might also be desirable for a user to be able to immediately adjust the pressure to a wound at the time of an initial application of a dressing.
SUMMARYIn an aspect, a dressing for applying pressure to a patient target site is provided. The dressing includes longitudinally spaced first and second substrates each having a first surface and an oppositely facing second surface. The first surface of each of the first and the second substrates has an attachment member for attaching the dressing to the patient target site. An elastic spacer longitudinally extends between the first and the second substrates. The elastic spacer is biased to a first length. The elastic spacer is configured to be selectively moved between the first length and a second length. The second length is longer than the first length. A triggering element is removably joined to at least one of the second surface of the first substrate, the second surface of the second substrate, and the elastic spacer. The triggering element, when present, selectively maintains the elastic spacer at the second length and selectively prevents the elastic spacer from moving toward the first length. Portions of the triggering element are sequentially removable from at least one of the second surface of the first substrate, the second surface of the second substrate, and the elastic spacer such that as each portion of the triggering element is removed, the elastic spacer sequentially moves from the second length toward the first length. The sequential movement of the elastic spacer from the second length toward the first length responsively urges the first and second substrates longitudinally toward one another to apply a predetermined amount of longitudinal force to the patient target site.
In an aspect, a method for applying pressure to a patient target site is provided. A dressing having an elastic spacer longitudinally extending between longitudinally spaced first and second substrates is provided. The elastic spacer is adjusted from a first length to a second length. The second length is longer than the first length. A triggering element is joined to at least one of a second surface of the first substrate, a second surface of the second substrate, and the elastic spacer to selectively maintain the elastic spacer at the second length and, with the triggering element, selectively prevent the elastic spacer from achieving the first length. The first substrate is attached to a first side of the patient target site. The second substrate is attached to a second side of the patient target site opposite the first side, to longitudinally span the patient target site with the elastic spacer. Portions of the triggering element are sequentially removed. The sequential removal of portions of the triggering element causes the elastic spacer to sequentially move from the second length to the first length. The sequential movement of the elastic spacer from the second length to the first length responsively urges the first and second substrates longitudinally toward one another to apply a predetermined amount of longitudinal force to the patient target site.

An elastic spacer longitudinally extends between the first and the second substrates. The elastic spacer is biased to a first length. The elastic spacer is configured to be selectively moved between the first length and a second length. The second length is longer than the first length. A triggering element is laterally removably inserted into a corresponding expandable cavity of the elastic spacer. The triggering element, when present, selectively maintains the elastic spacer at the second length and selectively prevents the elastic spacer from moving toward the first length. The triggering element is removable from the corresponding expandable cavity of the elastic spacer such that as the triggering element is removed, the elastic spacer moves from the second length toward the first length.

A dressing 100 for applying pressure to a patient target site is provided. As shown in
As shown in
As shown in
As shown in
The dressing 100 may include at least one triggering element 730. The at least one triggering element 730 might be removably attached to at least one of the second surface 110 of the first substrate 102, the second surface 112 of the second substrate 104, and the second surface 126 of the elastic spacer 122. The attachment between the triggering element 730 and at least one of the second surface 110 of the first substrate 102, the second surface 112 of the second substrate 104, and the second surface 126 of the elastic spacer 122 might be an adhesive attachment, a magnetic attachment, a hook and loop attachment, a button attachment, any other appropriate attachment, or any combination thereof. The triggering element 730, when present, selectively maintains the elastic spacer 122 at a length longer than the first elastic spacer length L1, such as the second length L2, and selectively prevents the elastic spacer 122 from moving toward the first length L1.
In use of the dressing 100 having the triggering element 730′, a target patient site T is located. The target patient site T might be a location on a patient that is desirable to apply a predetermined amount of pressure to the patient's skin, to a wound, to close a wound, to keep a wound closed, to remove tension from a wound, to redistribute tension away from a wound, and/or for any other purpose, though a wound closure use environment is provided here as an example. The elastic spacer 122 is adjusted from the first elastic spacer length L1 to the second elastic spacer length L2. The triggering element 730 formed from one removable portion 732 is attached to at least one of the second surface 110 of the first substrate 102, the second surface 112 of the second substrate 104, and the second surface 126 of the elastic spacer 122 to selectively maintain the elastic spacer 122 at the second elastic spacer length L2 and, with the triggering element 730′, selectively prevent the elastic spacer 122 from achieving the first elastic spacer length L1. The process of adjusting the elastic spacer 122 from the first elastic spacer length L1 to the second elastic spacer length L2 and attaching the triggering element 730′ to at least one the second surface 110 of the first substrate 102, the second surface 112 of the second substrate 104, and the second surface 126 of the elastic spacer 122 might be completed prior to use, or during use of the dressing 100.
As shown in
As shown in
The movement of the elastic spacer 122 from the second elastic spacer length L2 toward the first elastic spacer length L1 responsively urges the first and second substrates 102, 104 longitudinally toward one another to apply a predetermined amount of longitudinal force to the patient target site T. In particular, the urging of the first and second substrates 102, 104 longitudinally toward one another responsively urges the first and the second sides T1, T2 of the target patient site T longitudinally toward one another to apply a predetermined amount of longitudinal force to the patient target site T. If the first and second sides T1, T2 are on opposing sides of an open wound, the responsive urging of the first and the second sides T1, T2 longitudinally toward one another might at least partially close the wound. T1 and T2 might already be in contact with each other when the dressing 100 is applied. In such case, the responsive urging of the first and second sides T1, T2 longitudinally toward one another further compresses the target patient site T, such as a target patient site T containing a wound, to allow the target patient site T to evert and/or to redistribute tension away from the target patient site T.
The sequence of operation of the dressing 100 having the trigging element 730″ formed from the at least two removable portions 732a, 732b, 732c is substantially similar to the sequence of operation depicted in
The sequential movement of the elastic spacer 122 from the second elastic spacer length L2 toward the first elastic spacer length L1 responsively urges the first and second substrates 102, 104 longitudinally toward one another to apply a predetermined amount of longitudinal force to the patient target site T. In particular, the urging of the first and second substrates 102, 104 longitudinally toward one another responsively urges the first and the second sides T1, T2 of the target patient site T longitudinally toward one another to apply a predetermined amount of longitudinal force to the patient target site T. Because the movement of the elastic spacer 122 from the second elastic spacer length L2 to the first elastic spacer length L1 is sequential, the amount of longitudinal force applied to the target patient site T sequentially increases. Thus, a user can apply a predetermined amount of longitudinal force to the target patient site T by removing one of the at least two removable portions 732a, 732b, 732c, and increase the amount of longitudinal force by removing another of the at least two removable portions 732a, 732b, 732c.

In the example configuration of
When each expandable cavity 2540a, 2540b of the elastic spacer 122′″ is in the closed configuration, the elastic spacer 122′″ is biased to the first elastic spacer length L1 (
To selectively maintain the at least one expandable cavity 2540a, 2540b in the opened configuration, the dressing 100′″ may include a triggering element 730′″ formed from at least one removable portion 732′″ (shown here as removable portions 732a′″, 732b′″) that is removably inserted into the at least one expandable cavity 2540a, 2540b. The at least one removable portion 732a′″, 732b′″ might be in the form of a rigid bar or rod, though the at least one removable portion 732a′″, 732b′″ might have any desired form corresponding to the shape of the at least one expandable cavity 2540a, 2540b. The at least one removable portion 732a′″, 732b′″ has a longitudinal length that is about equal to the second cavity length L5. Thus, when the at least one removable portion 732a′″, 732b′″ is selectively inserted into the at least one expandable cavity 2540a, 2540b, the at least one expandable cavity 2540a, 2540b is maintained in the opened configuration. The at least one removable portion 732a′″, 732b′″ might have a lateral length, that is greater than, equal to, or less than the lateral length of the at least one expandable cavity 2540a, 2540b.
In use of the dressing 100′″ having the triggering element 730′″, a target patient site T is located. The elastic spacer 122′″ is adjusted from the first elastic spacer length L1 to the second elastic spacer length L2. The triggering element 730′″ formed from the at least one removable portion 732a′″, 732b′″ is inserted into the at least one expandable cavity 2540a, 2540b of the elastic spacer 122′″ to selectively maintain the elastic spacer 122′″ at the second elastic spacer length L2 and, with the triggering element 730′″, selectively prevent the elastic spacer 122′″ from achieving the first elastic spacer length L1. The process of adjusting the elastic spacer 122′″ from the first elastic spacer length L1 to the second elastic spacer length L2 and inserting the triggering element 730′″ into the at least one expandable cavity 2540a, 2540b of the elastic spacer 122′″ might be completed prior to use, or during use of the dressing 100′″.
Each removable cover 218, 220, when present, that is at least partially covering an attachment member 114, 116 of the first and second substrates 102, 104 may be removed from the first and second substrates 102, 104. As shown in
With the first and second substrates 102, 104 attached to the first and second sides T1, T2 of the target patient tissue site T, the at least one removable portion 732a′″, 732b′″ of the triggering element 730′″ may be selectively laterally removed from the at least one expandable cavity 2540a, 2540b. The removal of the at least one removable portion 732a′″, 732b′″ causes the elastic spacer 122′″ to move from the second elastic spacer length L2 to the first elastic spacer length L1. The movement of the elastic spacer 122′″ from the second elastic spacer length L2 toward the first elastic spacer length L1 responsively urges the first and second substrates 102, 104 longitudinally toward one another to apply a predetermined amount of longitudinal force to the patient target site T. In particular, the urging of the first and second substrates 102, 104 longitudinally toward one another responsively urges the first and the second sides T1, T2 of the target patient site T longitudinally toward one another to apply a predetermined amount of longitudinal force to the patient target site T.
As shown in
The sequential movement of the elastic spacer 122′″ from the second elastic spacer length L2 toward the first elastic spacer length L1 responsively urges the first and second substrates 102, 104 longitudinally toward one another to apply a predetermined amount of longitudinal force to the patient target site T. In particular, the urging of the first and second substrates 102, 104 longitudinally toward one another responsively urges the first and the second sides T1, T2 of the target patient site T longitudinally toward one another to apply a predetermined amount of longitudinal force to the patient target site T. Because the movement of the elastic spacer 122′″ from the second elastic spacer length L2 to the first elastic spacer length L1 is sequential, the amount of longitudinal force applied to the target patient site T sequentially increases. Thus, a user can apply a predetermined amount of longitudinal force to the target patient site T by laterally removing one of the at least two removable portions 732a′″, 732b′″, and increase the amount of longitudinal force by laterally removing another of the at least two removable portions 732a′″, 732b′″.
As shown in
Although certain features shown in
It is contemplated that the dressing 100, 100′″ might be applied to certain medical instruments that are on opposing sides of a target patient site T so that the dressing 100, 100′″ is able to apply pressure, i.e., a longitudinal force, to the target site T through the medical instruments.
It is contemplated that the dressing 100, 100′″ might have other applications unrelated to a patient and/or a target patient site. For example, the dressing 100, 100′″ might be used in any situation that is desirable to apply pressure, i.e., a longitudinal force, to a site by urging two opposing sides toward one another.
While aspects of this disclosure have been particularly shown and described with reference to the example aspects above, it will be understood by those of ordinary skill in the art that various additional aspects may be contemplated. For example, the specific methods described above for using the apparatus are merely illustrative; one of ordinary skill in the art could readily determine any number of tools, sequences of steps, or other means/options for placing the above-described apparatus, or components thereof, into positions substantively similar to those shown and described herein. In an effort to maintain clarity in the Figures, certain ones of duplicative components shown have not been specifically numbered, but one of ordinary skill in the art will realize, based upon the components that were numbered, the element numbers which should be associated with the unnumbered components; no differentiation between similar components is intended or implied solely by the presence or absence of an element number in the Figures. Any of the described structures and components could be integrally formed as a single unitary or monolithic piece or made up of separate sub-components, with either of these formations involving any suitable stock or bespoke components and/or any suitable material or combinations of materials; however, the chosen material(s) should be biocompatible for many applications. Any of the described structures and components could be disposable or reusable as desired for a particular use environment. Any component could be provided with a user-perceptible marking to indicate a material, configuration, at least one dimension, or the like pertaining to that component, the user-perceptible marking potentially aiding a user in selecting one component from an array of similar components for a particular use environment. A “predetermined” status may be determined at any time before the structures being manipulated actually reach that status, the “predetermination” being made as late as immediately before the structure achieves the predetermined status. The term “substantially” is used herein to indicate a quality that is largely, but not necessarily wholly, that which is specified—a “substantial” quality admits of the potential for some relatively minor inclusion of a non-quality item. Though certain components described herein are shown as having specific geometric shapes, all structures of this disclosure may have any suitable shapes, sizes, configurations, relative relationships, cross-sectional areas, or any other physical characteristics as desirable for a particular application. Any structures or features described with reference to one aspect or configuration could be provided, singly or in combination with other structures or features, to any other aspect or configuration, as it would be impractical to describe each of the aspects and configurations discussed herein as having all of the options discussed with respect to all of the other aspects and configurations. A device or method incorporating any of these features should be understood to fall under the scope of this disclosure as determined based upon the claims below and any equivalents thereof.
Other aspects, objects, and advantages can be obtained from a study of the drawings, the disclosure, and the appended claims.
