Description

Technical Field

[0001] This utility model relates to the field of medical device assistance, and more specifically to a three-dimensional transparent fixation dressing in the shape of an airplane tail fin for VSD dressing. Background Technology

[0002] Vacuum-assisted closure (VSD) is a novel and highly effective drainage technique that promotes wound healing through controlled negative pressure. It enables safe and rapid healing of traumatic soft tissue wounds and chronic infections, and is now widely used to heal various difficult-to-treat wounds. For VSD dressings, a good seal is crucial to ensuring the effectiveness of negative pressure drainage. Currently, widely used methods for sealing the drainage tube with transparent VSD dressings include the "overlapping method," "membrane method," or "punch-hole method." However, in areas with frequent limb movement, the drainage tube may leak due to bubbling caused by movement, making it difficult to securely fix the tube. This necessitates frequent dressing changes by medical staff, increasing workload, wasting dressings, and, more importantly, directly affecting the sustainability of drainage. In some cases, it can even increase the risk of wound exposure and infection, a persistent problem in the field.

[0003] To address the issue of air leakage due to inadequate sealing, some existing technologies offer solutions, but none are entirely ideal. One such solution involves 3D dressings, a novel wound care material that better adapts to wound shapes, such as irregular wounds, providing effective protection and treatment. The design of 3D dressings allows them to conform to irregular areas of the body, such as joints and folds, offering a more comfortable and safer care experience. With technological advancements, 3D printing technology is increasingly used to create personalized 3D dressings. However, this technology remains limited due to its high cost.

[0004] For example, Chinese patent CN0330905U describes a three-dimensional dressing, which includes a dressing body. The dressing body includes a central protrusion and a flat portion surrounding the protrusion. The flat portion extends outward from the lower edge of the protrusion. A receiving cavity is formed within the protrusion to accommodate the protruding skin of the implanted port. In this solution, by applying the three-dimensional dressing to the protruding skin of the port, the port needle can be more firmly fixed to the patient's skin. However, although this solution can avoid skin damage, its structure is not suitable for the needs of VSD drainage because it cannot insert a drainage tube.

[0005] For example, Chinese patent CN3310898U describes a disposable medical adhesive dressing, which includes a dressing body with at least one suction tube and a suction needle built into it. One end of the suction tube is closed and the other end extends out of the dressing body. The end of the suction tube extending out of the dressing body is connected to at least two ports, namely a flushing port and a negative pressure port. The medical dressing in this solution solves the problem of drainage tube exit, and is particularly effective in preventing leakage in abdominal wounds. However, due to the design of many ports, the number of leakage points increases, making it difficult to achieve a sealed state, and leakage problems still occur.

[0006] For example, Chinese patent CN4967668U describes a three-dimensional dressing for surgical drainage tube sites, with reference to Figure 8 As shown, the device includes a skin fixation patch 100 and a drainage tube fixation patch 200. The drainage tube 300 is fixed to the skin fixation patch 100 and the drainage tube fixation patch 200 by an adhesive tape 230. In this solution, the patch can play a good role in fixing the drainage tube 300 when it is brought out on a flat surface. However, it cannot be applied to non-flat areas or multiple tubes because it is not designed for these scenarios.

[0007] It is evident that there is an urgent need in the existing technology for a medical dressing suitable for VSD that can minimize air leakage and reduce skin pressure damage. Utility Model Content

[0008] In view of the technical problems existing in the prior art, the purpose of this utility model is to provide a simple, easy-to-operate, disposable, three-dimensional transparent, aircraft tail-shaped fixative dressing for VSD dressings. This dressing product can fit the drainage tube area at the edge of the VSD dressing, can minimize the appearance of air leakage caused by local blistering due to the movement and pulling of the drainage tube, and can minimize the pressure damage to the skin caused by the VSD drainage tube.

[0009] According to one aspect of this utility model, a three-dimensional transparent fixation dressing in the shape of an aircraft tail fin is provided for VSD dressing. The fixation dressing is used to fix the VSD dressing and the drainage tube. The fixation dressing is characterized in that it comprises a dressing body made primarily of release paper, the dressing body including a planar area and a tail fin area, the planar area and the tail fin area being integrally formed or separately formed. The planar area is used to fix the VSD dressing, and the tail fin area is used to fix the drainage tube. The planar area includes an upper planar area and a lower planar area, the upper planar area being connected to the lower planar area via a centerline. The lower planar area is divided into a lower left planar area and a lower right planar area by the tail fin area. The tail fin area symmetrically arranges the left and right tail fin areas in a foldable manner. The left tail fin area is connected to the lower left planar area, and the right tail fin area is connected to the lower right planar area. In the folded state, the tail fin area causes the upper and lower planar areas to be located on the same plane. In the open state, it forms a space to accommodate the drainage tube and is shaped to seal and enclose the drainage tube.

[0010] According to the above technical solution, the tail-wing-shaped three-dimensional transparent fixed patch includes a first positioning line (1) for positioning the middle part of the drainage tube, the first positioning line is the connecting line between the left and right sides of the tail wing area, and in the vertically upright state, its projection in the vertical direction coincides with the line where the plane area intersects with the tail wing area, and a second positioning line (8) for positioning the patch body relative to the human skin and extending along the center line, the intersection of the second positioning line and the first positioning line is the point where the drainage tube exits the skin.

[0011] Furthermore, according to the above technical solution, the fixed dressing is foldable relative to the centerline.

[0012] Furthermore, the feature is that the angle between the tail fin area and the planar area in the folded state can be any angle between 0 and 180 degrees.

[0013] Furthermore, the second positioning line (8) and the first positioning line (1) form an angle of 30-60 degrees in the horizontal direction when the included angle is 0 degrees or 180 degrees.

[0014] Furthermore, the fixed dressing body is characterized by being made of soft, deformable, and high-strength release paper.

[0015] Furthermore, the fixed dressing plane area is characterized by a length of 12cm and a width of 10cm, and its shape is rectangular, rounded rectangular, elliptical, or adapted to irregular wound shapes.

[0016] Furthermore, the feature is that, in the open state, the three-dimensional portion formed by the first positioning line of the fixed dressing tail wing area has a length of 10cm, which is used to wrap the drainage tube.

[0017] Furthermore, the feature is that when the tail fin area is folded and perpendicular to the planar area, the first positioning line and the second positioning line intersect in a T-shape.

[0018] Furthermore, the feature is that when the tail fin area is fully opened to be on the same plane as the lower left and lower right plane areas, the first positioning line and the second positioning line intersect in a T-shape. According to this utility model, it has the following outstanding technical effects and advantages:

[0019] (1) Good sealing performance: The rear end of this utility model is shaped like the tail of an airplane. This part is used to better fit the drainage channel in the VSD dressing. The dressing fully wraps the channel and forms an oblique triangular frenulum membrane between the dressing and the patient's skin. It effectively fits the area between the VSD dressing and the channel, and between the channel and the patient's skin, reducing the phenomenon of air leakage caused by local blistering of the dressing due to the movement of the drainage tube, and improving the sealing performance during the drainage process.

[0020] (2) High safety: After the tube is pasted, the tube is positioned as a "high platform". Due to the dressing, the tube can support part of the pressure, avoiding the tube from pressing directly on the patient's skin and causing new pressure damage. This reduces the pressure on the wound and accelerates wound healing.

[0021] (3) Simple to use (with positioning line assistance). The present invention has a “T” positioning line on the dressing. When operating, the medical staff align the intersection of the “T” of the present invention with the point where the tube needs to be raised. The horizontal part of the “T” extends about 2-3 cm beyond the edge of the VSD dressing, and the center line of the drainage tube is aligned with the vertical part of the “T”.

[0022] (4) Easy to operate: The fixed dressing of this utility model is a transparent fixed dressing, which is suitable for observing the color and characteristics of the liquid drawn out by the drainage tube. This guide makes it easy for medical staff to operate (once the dressing is applied crookedly, the dressing can only be discarded).

[0023] (5) Wide applicability and high flexibility: The three-dimensional transparent fixation dressing of this utility model has a three-dimensional part of 10cm that can wrap various drainage tubes (currently models Fr16~Fr36), and is compatible with the models of disposable VSD foam dressings currently used in clinical practice. The material of this utility model is soft and can be applied to wounds of any shape and size; it can also be stacked and combined. If the dressing is too large, it can be trimmed; if the dressing is too small, it can be stacked. It can cover drainage tubes in various directions. It effectively solves the problem of effective adhesion of tubes draining from VSD dressings in any direction, and has no restrictions on the shape or flatness of the wound.

Detailed Implementation

[0034] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. Those skilled in the art will understand that this description is exemplary and that the present invention is not limited to these specific embodiments.

[0035] Figure 1 This is a perspective view of a VSD dressing for an aircraft tail fin in an open state, according to a specific embodiment of the present invention. The left image in Figure 2 shows a folded diagram of the left side, and the right image shows a folded diagram of the right side. Figure 3 This is a side view of the tail fin with the tail fin folded.

[0036] like Figures 1-3 As shown in Figure 6, the fixing dressing includes a dressing body made of release paper. The dressing body includes a planar area 5 for fixing the VSD dressing and a tail area 2. The tail area 2 is used to fix the drainage tube. Figure 1 When the tail section 2 is fully opened, the upper surface of the planar section 5 rises up to form an arc shape. Figure 2a and Figure 2b In the case where the tail fin area 2 is fully folded, the entire planar area 5 forms a plane. Figure 2a This is a schematic diagram showing the tail section folding to the left. Figure 2b This is a schematic diagram showing the tail section folding to the right.

[0037] The planar region 5 and the tail fin region 2 are integrally formed or separately formed, wherein, see Figure 1 As shown in Figure 6, the planar area 5 includes multiple release paper areas, specifically: release paper area A 3 and its release paper area A dividing line 4, release paper area B 6 and its dividing line 7, release paper area C 9 and its dividing line 10, release paper area D 11 and its dividing line 12, release paper area E 16 and its dividing line 17, and release paper area I 19 and release paper area J 20 on the back side. The dividing lines are used to manually tear off the corresponding release paper area along the dividing lines.

[0038] The planar area 5 includes an upper planar area and a lower planar area. The upper planar area is connected to the lower planar area by a centerline. Multiple release paper areas in the planar area 5 can be located in the lower planar area. The lower planar area is divided into a lower left planar area and a lower right planar area by the tail fin area 2. Each release paper area can be distributed in the lower left planar area and the lower right planar area.

[0039] The tail fin area 2 is symmetrically arranged with a left tail fin area and a right tail fin area in a foldable manner. The left tail fin area is connected to the lower left plane area, and the right tail fin area is connected to the lower right plane area. When the tail fin area 2 is folded, the upper plane area and the lower plane area are located on the same plane. When the tail fin area 2 is open, it forms a space to accommodate the drainage tube and is in a shape that seals and wraps the drainage tube.

[0040] In a preferred embodiment, the tail-shaped three-dimensional transparent fixation patch includes a first positioning line 1 for positioning the middle part of the drainage tube, the first positioning line 1 being the connecting line between the left and right sides of the tail-wing area 2, and in the vertically upright state, its projection in the vertical direction coincides with the line intersecting the plane area 5 and the tail-wing area 2; and a second positioning line 8 for positioning the patch body relative to the human skin and extending along the center line, the intersection of the second positioning line and the first positioning line being the point where the drainage tube exits the skin.

[0041] In a preferred embodiment, the fixation dressing is foldable relative to the midline. The upper and lower planar areas are folded to achieve folding of the planar areas.

[0042] In a preferred embodiment, the angle between the tail fin region 2 and the planar region 5 in the folded state can be any angle between 0 and 180 degrees. Figure 2a and Figure 2b A schematic diagram showing tail section 2 in a folded state. (See attached image) Figure 2a and Figure 2b It can be seen that the tail fin area 2 in the folded state can be at any angle relative to the left plane area and the right plane area. That is, the tail fin area 2 can be completely folded to the left, or completely folded to the right, or at any angle when folded to the left or right.

[0043] Furthermore, when the included angle is 0 degrees or 180 degrees, the second positioning line 8 and the first positioning line 1 form an angle of 30 to 60 degrees in the horizontal direction.

[0044] Furthermore, the fixing patch body is made of soft, deformable, and high-strength release paper.

[0045] Furthermore, the dimensions of the planar area 5 are preferably 12cm in length and 10cm in width, and the shape is rectangular, rounded rectangular, elliptical, or other shapes adapted to irregular wounds.

[0046] Furthermore, the length of the three-dimensional portion formed by the first positioning line 1 in the fixed dressing tail wing area 2 when it is in the open state is preferably 10cm, which is used to wrap the drainage tube.

[0047] Furthermore, when the tail wing area 2 is folded and perpendicular to the planar area 5, the first positioning line 1 and the second positioning line 8 intersect in a T-shape.

[0048] Furthermore, when the tail fin area 2 is fully opened to be on the same plane as the lower left and lower right plane areas, the first positioning line 1 and the second positioning line 8 intersect in a T-shape.

[0049] In this embodiment of the invention, before using the fixation dressing, the surgeon thoroughly cleans the patient's wound surface, fills it with VSD foam dressing, inserts the drainage tube, and then applies a semi-transparent large dressing. Near the exit tube, a three-dimensional transparent fixation dressing in the shape of an airplane tail fin, as patented in this invention, is applied. The release paper F area 13 is peeled off and applied to the second positioning line 8, aligned with a distance of 2-3 cm from the VSD foam dressing, and the first positioning line 1, aligned with the center line of the drainage tube plane. The VSD foam dressing and drainage tube are smoothed and shaped.

[0050] Separate and erect the tail-wing shaped three-dimensional transparent fixation dressing (tail-wing area 2), peel off the release paper area I 19, peel off the release paper area J 20, the drainage tube is tightly attached to the first positioning line 1 and wrapped around the entire drainage tube, and the excess part of the two dressings are attached to each other to form a tie.

[0051] Tear off release paper area G 14 and release paper area H 15, apply it firmly to the patient's skin and smooth it out.

[0052] Remove release paper from areas A (3), B (6), C (9), D (11), and E (16). Remove the label tape from area 18, write the responsible person and the date and time, and affix it near the pipe. This completes the process.

[0053] Figure 8 This is a schematic diagram of the structure of a three-dimensional dressing for surgical drainage tubes in the prior art.

[0054] The present invention has been described in detail above with reference to the embodiments. The rear end of the present invention stands upright, resembling the shape of an airplane tail fin. This shape allows for better adhesion to the drainage channels within the VSD dressing. The dressing fully encloses the channels, reducing the risk of air leakage caused by blistering due to movement and stretching of the drainage tubes, thus improving the seal during drainage. The dressing also supports some of the pressure on the channels, preventing direct pressure damage to the patient's skin and reducing pressure on the wound, thereby accelerating wound healing. It can cover drainage tubes in various directions, effectively solving the problem of effective adhesion of drainage channels from any direction within the VSD dressing, and is unrestricted by the shape or flatness of the wound site.

[0055] Those skilled in the art will understand that various changes and modifications can be made to this utility model, and such changes and modifications shall fall within the scope of this application as long as they do not depart from the spirit and purpose of this utility model. The scope of protection of this utility model is defined by the appended claims.
