Description

[0001] Cross - Reference to Related Applications

[0002] This application claims priority to U.S. Application No. 17 / 993,122, filed on November 23, 2022, entitled "Modular Medical Dressing", the entire disclosure of which is incorporated herein by reference in its entirety. Background Technical Field

[0004] The present disclosure relates to modular medical dressings. More specifically, the present disclosure relates to modular medical dressings having a layered dressing arrangement having predefined tearable portions that can be torn from the layered dressing arrangement to reduce the surface area of the layered dressing arrangement.

[0005] Technical Considerations

[0006] There is an increasing medical trend towards remote patient monitoring and treatment. Intravenous (IV) therapy remains one of the most widely used methods for providing such remote monitoring and care to patients. IV therapy can refer to a medical technique for directly delivering fluids, medications, and / or nutrients into a patient's body by inserting an IV catheter into a vein at an IV insertion site. IV therapy can be used for fluid replacement, providing nutrition to people who cannot eat or drink by mouth, and / or administering medications or other medical therapies (e.g., blood products or electrolytes).

[0007] After an IV catheter is inserted at an IV insertion site, it is necessary to ensure that the IV catheter is not accidentally pulled out. Typically, an IV catheter is secured at the IV insertion site by an adhesive (e.g., tape) that attaches directly to the patient's skin. A medical dressing is then applied to the area around the IV insertion site to prevent contamination of the catheter and to keep the IV insertion site clean.

[0008] Healthcare providers must stock medical dressings in a variety of sizes to accommodate patients of various body sizes, from infants to adults. In addition, healthcare providers must separately stock fixation straps to hold the IV catheter in place. There is an increasing need to improve medical dressings to overcome the deficiencies of existing medical dressings. Summary of the Invention

[0037] Continue to refer to Figures 1 to 3 The modular medical dressing has a layered dressing device 102 and a predefined tearable portion 104 formed on the layered dressing device 102. The predefined tearable portion 104 can be torn from the layered dressing device 102 to reduce the surface area of the layered dressing device 102. In this way, as described herein, dressings of different sizes can be obtained from the same layered dressing device 102 by tearing a desired section of the predefined tearable portion 104.

[0038] Refer to Figures 2 to 3 The layered dressing device 102 of the modular medical dressing 100 has a stacked arrangement of a plurality of releasable adhesive layers. In particular, the layered dressing device 102 has a dressing layer 106 that has a first surface 108 and a second surface 110. The dressing layer 106 is disposed between a release layer 112 and a backing layer 114. Specifically, the release layer 112 is releasably adhered to the first surface 108 of the dressing layer 106, while the backing layer 114 is releasably adhered to the second surface 110 of the dressing layer 106.

[0039] As Figure 3 shown, the release layer 112 can have a first adhesive 115 for adhering to the first surface 108 of the dressing layer 106. The second surface 110 of the dressing layer 106 can have a second adhesive 116 for adhering to the backing layer 114. The second adhesive 116 can also be configured such that when the backing layer 114 is removed from the dressing layer 106, the second adhesive adheres to the patient's skin.

[0040] Refer to Figure 2 The layered dressing device 102 can have a generally rectangular shape. In some embodiments or aspects, a slot 118 can extend from the outer periphery of the layered dressing device 102. The slot 118 can be configured to receive an IV catheter line (not shown).

[0041] Continue to refer to Figure 2 The dressing layer 106 can be a transparent layer configured to allow an IV catheter and / or an IV insertion site to be visible through the transparent layer. In some embodiments or aspects, the dressing layer 106 can be made of a polyurethane material. In further embodiments or aspects, the dressing layer 106 can be made of a non-woven material, a woven fabric material, or a foam material (e.g., a silicone foam material).

[0042] Continue to refer to Figure 2 The backing layer 114 can be made of a paper material. In some embodiments or aspects, the backing layer 114 can be made of a non-woven material, a woven fabric material, or a foam material. The backing layer 114 can be sized and shaped to correspond to the shape of the dressing layer 106.

[0043] Continue to refer toFigure 2 , the release layer 112 can be made of paper material. In further embodiments or aspects, the release layer 112 can be made of a plastic film material (e.g., polyester, polyvinyl chloride, polyethylene, or polypropylene film material). As described herein, the release layer 112 has a first adhesive 115 for adhering to the first surface 108 of the dressing layer 106. As described herein, at least a portion of the release layer 112 can be configured to serve as a securing strap for securing the catheter to the anatomical structure.

[0044] Continuing to refer Figure 2 , a predefined tearable portion 104 is formed on each layer of the layered dressing device 102. In some embodiments or aspects, the predefined tearable portion 104 can be a plurality of perforations that extend through at least a portion of each of the dressing layer 106, the release layer 112, and the backing layer 114. In some embodiments or aspects, these perforations can be formed during the manufacturing process of the layered dressing device 102, for example, using a roller having a plurality of protrusions to form them.

[0045] The predefined tearable portion 104 can have a plurality of first tear lines 120 that are connected to define a first tearable portion 122. The predefined tearable portion 104 can also have a plurality of second tear lines 124 that are spaced apart from the plurality of first tear lines 120 and that are connected to define a second tearable portion 126. The first tearable portion 122 and the second tearable portion 126 are removably connected to the main portion 128 of the layered dressing device 102. In this way, the first tearable portion 122 and the second tearable portion 126 allow the size of the layered dressing device 102 to be reduced to fit a patient with a smaller body size. The ability to configure the layered dressing device 102 into three different sizes depending on the presence or absence of the first tearable portion 122 and the second tearable portion 126 in the main portion 128 simplifies the inventory management for healthcare professionals, who only need to stock a single modular medical dressing 100.

[0046] Refer Figure 4 , to reduce the size of the modular medical dressing 100 to an intermediate size, the first tearable portion 122 is removed from the layered dressing device 102 by tearing along the plurality of first tear lines 120. Then, the backing layer 114 can be removed from the dressing layer 106 to expose the second adhesive 116 of the dressing layer 106 (as Figure 3 shown), thereby allowing the dressing layer 106 to be applied to the patient's skin. In the case where the dressing layer 106 is applied to the patient's skin, the release layer 116 can be removed from the dressing layer 106.

[0047] Refer Figure 5, To reduce the size of the modular medical dressing 100 to its minimum size, the first tearable portion 122 is removed from the main portion 128 of the layered dressing device 102 by tearing along a plurality of first tear lines 120 and the second tearable portion 126 is removed by tearing along a plurality of second tear lines 124. In some embodiments or aspects, removing the second tearable portion 126 from the main portion 128 also removes the first tearable portion 122. Then, the backing layer 114 can be removed from the dressing layer 106 to expose the second adhesive 116 of the dressing layer 106 (as Figure 3 shown), thereby allowing the dressing layer 106 to be applied to the patient's skin. In the case where the dressing layer 106 is applied to the patient's skin, the release layer 116 can be removed from the dressing layer 106.

[0048] Reference Figures 6 to 8 , the release layer 114 is shown separated from the remaining layers of the layered dressing device 102. As described herein, since the release layer 114 has a first adhesive 115, multiple portions of the release layer 114 can be used as securing straps. As Figure 6 shown, a first portion 130 of the release layer 114 can be removed by tearing along a plurality of first tear lines 120. In the case where the first portion 130 of the release layer 114 is removed from the remaining portion of the release layer 114, the first portion 130 can be divided into two U-shaped segments by tearing a pair of first dividing lines 132. The resulting U-shaped segments define a first securing strap 134 that can be used to secure the IV catheter 200 and / or the dressing layer 106 to the patient's skin (see Figures 9 to 10 ).

[0049] Reference Figures 7 to 8 , the first securing strap 134 can be further divided into a plurality of second securing straps 136 by tearing a pair of second dividing lines 138. The resulting linear segments define the second securing straps 136 that can be used to secure the IV catheter 200 and / or the dressing layer 106 to the patient's skin (see Figure 11 ). In this way, a healthcare practitioner can select the size of the securing strap according to the patient's body size.
