Description

Technical Field

[0001] This utility model relates to the field of medical dressings, and in particular to a dressing core incision structure and wound dressing. Background Technology

[0002] Patent publication CN213465619U discloses a wound dressing with two types of cuts: arc cuts and V-shaped cuts. The included angle of the V-shaped cut is 120 degrees. Some notches are a combination of arc cuts and V-shaped cuts. Since both arc cuts and V-shaped cuts have stress concentration areas, the effect of weakening the interfacial bonding force of this dressing core structure is relatively poor. Therefore, the dressing core with this structure is not easy to break when it is made into a wound dressing, and it is easy to cause discomfort to the user when using it. Utility Model Content

[0003] To address the aforementioned problems, this invention proposes a core-filling cut structure. The 60-degree angle formed by the tangent effectively disrupts the continuous structure of the material, disperses stress concentration areas, and weakens interfacial bonding, resulting in a significant decrease in the ductility of the core-filling material. This makes it easier to tear when made into a dressing and provides a more comfortable user experience.

[0004] The technical solution adopted by this utility model is as follows:

[0005] A core-filling cut structure includes a first tangent and a second tangent. The first tangent is a straight first tangent, and the second tangent is a straight second tangent. One end of the first tangent is connected to one end of the second tangent. The length of the first tangent is equal to the length of the second tangent, and the width of the first tangent is equal to the width of the second tangent. The angle formed by the first tangent and the second tangent is 60 degrees.

[0006] In this type of cut structure, the included angle between the two tangents is 60 degrees. The pattern formed by the combination of the two tangents at a 60-degree angle effectively cuts and disrupts the continuous structure of the material, disperses stress concentration areas, and weakens the interfacial bonding force. This results in a significant decrease in the extensibility of the core material, making it easier to tear when made into a dressing and providing a more comfortable user experience. At the same time, this type of cut structure allows for as many cuts as possible per unit area of ​​the fabric, ensuring less friction during stretching, maintaining the cut material as a whole, and making it easy for the user to tear during use.

[0007] In summary, the 60-degree angle formed by the tangent in this type of cut effectively disrupts the continuous structure of the material, disperses stress concentration areas, and weakens interfacial bonding, resulting in a significant decrease in the ductility of the dressing material. This makes it easier to tear when made into a dressing and provides a more comfortable user experience.

[0008] Optionally, it also includes a third tangent and a fourth tangent, wherein the third tangent is a straight line and the fourth tangent is a straight line, one end of the third tangent is connected to one end of the fourth tangent, the width of the third tangent is equal to the width of the fourth tangent, and the angle formed by the third tangent and the fourth tangent is 60 degrees.

[0009] Optionally, one end of the third tangent is connected to the fourth tangent, and the first tangent, the third tangent, and the fourth tangent have the same shape and size.

[0010] Optionally, a fifth tangent line is also included, wherein the fifth tangent line has the same collision magnitude as the first tangent line, and one end of the fifth tangent line is connected to the second tangent line and the third tangent line.

[0011] Optionally, the angle between the fifth tangent and the second tangent is 60 degrees, and the angle between the third tangent and the fifth tangent is 60 degrees.

[0012] In the above structure, the included angles formed by the tangents are almost all 60 degrees, and there is only one included angle of 240 degrees, which is formed by the second tangent and the third tangent.

[0013] Optionally, the first tangent and the fourth tangent are parallel.

[0014] Optionally, the angle between the second tangent and the third tangent is 60 degrees, the angle between the fifth tangent and the second tangent is 120 degrees, and the angle between the fifth tangent and the third tangent is 120 degrees.

[0015] The above structure has two 120-degree included angles, and the remaining included angles are all 60 degrees.

[0016] Optionally, the first tangent is parallel to the third tangent, and the second tangent is parallel to the fourth tangent.

[0017] A wound dressing employs the core incision structure described above.

[0018] The beneficial effects of this utility model are: the 60-degree angle formed by the tangent effectively disrupts the continuous structure of the material, disperses stress concentration areas, and weakens the interfacial bonding force, resulting in a significant decrease in the ductility of the dressing material. This makes it easier to tear when making dressings and provides users with a more comfortable experience. Attached Figure Description

[0026] Example 1

[0027] As attached Figure 1 As shown, a core-filling cut structure includes a first tangent 1 and a second tangent 2.

The length of the first tangent 1 is equal to the length of the second tangent 2, the width of the first tangent 1 is equal to the width of the second tangent 2, and the angle formed by the first tangent 1 and the second tangent 2 is 60 degrees.

[0028] In this type of cut structure, the included angle between the two tangents is 60 degrees. The pattern formed by the combination of the two tangents at a 60-degree angle effectively cuts and disrupts the continuous structure of the material, disperses stress concentration areas, and weakens the interfacial bonding force. This results in a significant decrease in the extensibility of the core material, making it easier to tear when made into a dressing and providing a more comfortable user experience. At the same time, this type of cut structure allows for as many cuts as possible per unit area of ​​the fabric, ensuring less friction during stretching, maintaining the cut material as a whole, and making it easy for the user to tear during use.

[0029] In summary, this type of cut, with a 60-degree angle formed by the tangent, effectively disrupts the continuous structure of the material, disperses stress concentration areas, and weakens interfacial bonding. This results in a significant decrease in the ductility of the dressing material, making it easier to tear when made into a dressing and providing a more comfortable user experience.

The length of the first tangent 1 is equal to the length of the second tangent 2, the width of the first tangent 1 is equal to the width of the second tangent 2, and the angle formed by the first tangent 1 and the second tangent 2 is 60 degrees.

[0038] In this type of cut structure, the included angle between the two tangents is 60 degrees. The pattern formed by the combination of the two tangents at a 60-degree angle effectively cuts and disrupts the continuous structure of the material, disperses stress concentration areas, and weakens the interfacial bonding force. This results in a significant decrease in the extensibility of the core material, making it easier to tear when made into a dressing and providing a more comfortable user experience. At the same time, this type of cut structure allows for as many cuts as possible per unit area of ​​the fabric, ensuring less friction during stretching, maintaining the cut material as a whole, and making it easy for the user to tear during use.

[0039] In summary, this type of cut, with a 60-degree angle formed by the tangent, effectively disrupts the continuous structure of the material, disperses stress concentration areas, and weakens interfacial bonding.

[0047] A wound dressing having the structure shown in Example 1 or Example 2.

[0048] To further verify the performance results of the incision structures shown in Embodiments 1 and 2 of this application, a comfort evaluation test was conducted using the wound dressings from the incisions in Embodiments 1 and 2 of this application, along with the wound dressing shown in CN213465619U. The test method adopted was YYT 0471.4-2004 Test Method for Contact Wound Dressings. The test structures are shown in Table 1 below.

[0050]

[0051] In the table above, Experimental Example 1 uses the incision shown in Example 1, Experimental Example 2 uses the incision shown in Example 2, and Control Example 1 uses the incision from CN213465619U.
