Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and specifically to an auxiliary fixation dressing. Background Technology

[0002] Implantable venous access ports require specialized needles for fixation. However, the accompanying non-woven fabric dressing is circular with a diameter of only 6cm, insufficient to completely cover the 10×12cm sterilization area, posing a risk of contamination to the vicinity of the needle. In cases of moist skin or eczema, the needle can easily slip off. Currently, clinical practice often employs a double-fixation method using a non-woven fabric dressing and a special dressing. However, with this special dressing, the pre-incision must ensure the top protective layer of the dressing is removed before applying the bottom dressing; otherwise, entanglement can easily occur. Furthermore, to prevent incomplete closure of the pre-incision dressing openings, the bottom dressing must completely cover the top dressing, creating tension and posing a risk of tension injury. The dressing application process requires removing multiple protective layers, and the top protective layer lacks an easy-tear design, making it difficult to remove. This removal process must be performed on the patient's skin, increasing patient discomfort, prolonging the procedure, and lacking a site for recording maintenance dates.

[0003] Therefore, existing auxiliary fixation dressings are not tightly connected, resulting in insufficient skin coverage and difficulty in removal. Utility Model Content

[0004] The purpose of this invention is to overcome the problems of loose connection of auxiliary fixation dressings and difficulty in tearing them off in the existing technology, and to provide an auxiliary fixation dressing that covers enough skin surface, makes it easy to remove the protective cover, and is easy to tear off.

[0005] To achieve the above objectives, this utility model provides an auxiliary fixation dressing, which includes an inner layer, a lower protective layer, and an upper protective layer. The lower protective layer and the upper protective layer are respectively attached to the lower and upper surfaces of the inner layer. The auxiliary fixation dressing has a pre-cut, which is located away from the edges of the inner layer, the lower protective layer, and the upper protective layer. The lower protective layer has a lower cutting line along the lower surface of the inner layer in a first direction, and the upper protective layer has an upper cutting line along the upper surface of the inner layer in a second direction.

[0006] Preferably, the inner layer and the lower protective layer have a first pre-cut, and the upper protective layer has a second pre-cut, the area of ​​the second pre-cut being larger than the area of ​​the first pre-cut.

[0007] Preferably, the first pre-cut is circular and the second pre-cut is rectangular.

[0008] Preferably, the first pre-cut and the second pre-cut are disposed in the middle of the inner layer, the lower protective layer and the upper protective layer.

[0009] Preferably, the projections of the first direction and the second direction onto the inner layer are parallel to each other.

[0010] Preferably, the lower cutting line divides the lower protective layer into two independent protective pages; and / or, The upper protective layer is ring-shaped, and the upper cutting line divides the upper protective layer into annular strips.

[0011] Preferably, the inner layer comprises an adhesive, the components of which include polyacrylic acid; and / or, The inner layer is made of polyethylene.

[0012] Preferably, the auxiliary fixation dressing further includes a label, which is detachably attached to the upper protective layer.

[0013] Preferably, the label is longer than 5cm and wider than 0.7mm.

[0014] Preferably, the inner layer is rectangular, the length of the rectangle is greater than 10cm, and the width of the rectangle is greater than 8cm; or, The upper protective layer has a 1.5cm longitudinal tangent, and the lower protective layer has a 0.5cm transverse tangent.

[0015] Based on common knowledge in the field, the above-mentioned preferred technical solutions can be freely combined to obtain the preferred embodiments of this application.

[0016] Through the above technical solution, the combination of the inner layer and the upper and lower protective layers provides double-layer protection, preventing the dressing from tearing during application. The pre-cut effectively fixes the puncture needle in the proper position, reducing the risk of displacement due to movement or external factors. The pre-cut allows the puncture needle or other medical devices to pass through easily during use, avoiding damage to the dressing during operation. The pre-cut is far from the edge of the auxiliary fixation dressing, making the dressing a complete structure and solving the problem of insufficient skin coverage caused by loose connections in existing technologies. In addition, the lower and upper protective layers have lower and upper cutting lines, which can effectively prevent adhesion or tearing during tearing or operation, ensuring the integrity and functionality of the dressing. Through the reasonable layered pre-cut design and the setting of upper and lower cutting lines, it is easy to tear off and can also effectively reduce the tension of the dressing on the skin, reducing skin damage and discomfort caused by tension and improving patient comfort.

[0021] This utility model provides an auxiliary fixation dressing 100, such as Figures 1-4 As shown, the auxiliary fixation dressing 100 includes an inner layer 1, a lower protective layer 2, and an upper protective layer 3. The lower protective layer 2 and the upper protective layer 3 are respectively attached to the lower and upper surfaces of the inner layer 1. The auxiliary fixation dressing 100 is provided with a pre-cut 4, which is away from the edges of the inner layer 1, the lower protective layer 2, and the upper protective layer 3. The lower protective layer 2 has a lower cutting line 21 along the lower surface of the inner layer 1 in a first direction, and the upper protective layer 3 has an upper cutting line 31 along the upper surface of the inner layer 1 in a second direction.

[0022] The combination of inner layer 1 and upper and lower protective layers 2 provides double-layer protection, preventing the dressing from tearing during application. The pre-incision 4 effectively secures the puncture needle in place, reducing the risk of displacement due to movement or external factors. The pre-incision 4 allows for easy passage of the puncture needle or other medical devices during use, avoiding damage to the dressing during operation. The pre-incision 4 is located away from the edge of the auxiliary fixation dressing 100, making the dressing a complete structure and solving the problem of insufficient skin coverage caused by loose connections in existing technologies. Furthermore, the lower protective layer 2 and upper protective layer 3 have lower cutting lines 21 and upper cutting lines 31, respectively, which effectively prevent adhesion or tearing during tearing or operation, ensuring the integrity and functionality of the dressing. Through the rational layering design of the pre-incision 4 and the placement of the upper cutting lines 31 and lower cutting lines 21, the upper and lower protective layers are easy to remove, effectively reducing the tension of the dressing on the skin, minimizing skin damage and discomfort caused by tension, and improving patient comfort.

[0023] In a preferred embodiment, the inner layer 1 and the lower protective layer 2 have a first pre-incision 41, and the upper protective layer 3 has a second pre-incision 42, the area of ​​which is larger than that of the first pre-incision 41. The larger second pre-incision 42 can better accommodate the shape and position of the puncture needle, allowing medical personnel to more easily pass the puncture needle or other medical devices through the upper protective layer 3 during operation, reducing the difficulty and complexity of the procedure. The smaller area of ​​the first pre-incision 41 can effectively disperse the tension of the dressing on the skin, reducing skin discomfort and damage caused by tension, ensuring that the dressing covers more surrounding skin during use, and improving patient comfort. Preferably, as... Figure 1 As shown, the inner layer 1 is rectangular, 12cm long and 10cm wide, with a 2.5cm diameter circular pre-cut in the center 4, which allows the non-traumatic needle extension tube to pass through and make the dressing fit better.

[0024] In a preferred embodiment, the first pre-incision 41 is circular, and the second pre-incision 42 is rectangular. The circular design is generally more suitable for the shape of the puncture needle, effectively surrounding the needle tip, reducing pressure on surrounding tissue, and lowering the risk of infection. The rectangular design provides a larger open area, allowing medical personnel greater flexibility in handling the puncture needle or other medical devices during operation, especially when adjustments or replacements are needed. The circular first pre-incision 41 can evenly distribute tension, reducing skin strain and minimizing discomfort and damage caused by tension. The rectangular second pre-incision 42 provides even greater flexibility during operation, further reducing pressure on the skin.

[0025] In a preferred embodiment, the first pre-incision 41 and the second pre-incision 42 are located in the middle of the inner layer 1, the lower protective layer 2, and the upper protective layer 3. Positioning the pre-incision 4 in the middle ensures the uniformity and symmetry of the dressing during use, enhancing overall stability and fixation, and preventing displacement or detachment due to uneven force. The central pre-incision 4 design makes it easier for medical personnel to locate the puncture point during operation, reducing operational complexity and improving efficiency. The central pre-incision 4 design also provides a better seal around the needle, reducing the risk of bacteria and other contaminants entering and ensuring a sterile environment during operation.

[0026] In a preferred embodiment, the projections of the first and second directions onto the inner layer 1 are parallel to each other. This effectively enhances the fixation of the dressing. This reduces the risk of needle displacement due to movement or external factors. The parallel cutting lines allow medical personnel to insert or adjust from the same position during operation, providing greater flexibility, especially in complex clinical environments. It also allows for a more even distribution of tension on the skin, reducing skin discomfort and damage caused by tension and improving patient comfort.

[0027] In a preferred embodiment, such as Figure 3 As shown, the lower cutting line 21 divides the lower protective layer 2 into independent protective sheets 5, allowing these two parts to be bent independently, forming a bending area. This makes it easier for medical personnel to remove the protective layer, allowing them to easily tear or fold it open, reducing operation time and complexity. The lower protective layer 2 is rectangular, divided into two symmetrical left and right sections in the middle, with a 2.5cm diameter circular pre-cut in the center. The two sides are folded upwards, with a 2cm wide folded portion for easy tearing.

[0028] The upper protective layer 3 is annular, and the upper cutting line 31 divides the upper protective layer 3 into annular strips, making it easier to adjust and fix during operation and providing better adaptability.

[0029] In a preferred embodiment, the inner layer 1 includes an adhesive, the components of which include polyacrylic acid; polyacrylic acid, as a component of the adhesive, has good adhesion and water resistance, which can ensure a firm fixation on the skin and reduce the risk of displacement due to movement or external factors.

[0030] The inner layer 1 is made of polyethylene. Specifically, it is low-density polyethylene, a skin-friendly material with good biocompatibility, which can reduce allergic reactions and discomfort, and improve patient comfort. Preferably, the protective page 5 is made of polyether-type polyurethane material.

[0031] In a preferred embodiment, such as Figure 4As shown, the auxiliary fixation dressing 100 also includes a label 6, which is detachably attached to the upper protective layer 3. The label 6 can be used to record important information, such as the date of application, user, and patient information, facilitating subsequent care and management. In a preferred embodiment, the label 6 is longer than 5 cm and wider than 0.7 mm. This length of paper label 6 is sufficient to accommodate necessary information, such as the operation date, user's name, and patient information. The longer label 6 provides more writing space, ensuring clear readability of the information. This width ensures that the label 6 is not easily torn when removed, while also maintaining a certain strength to prevent breakage due to pulling during use. Furthermore, the appropriate label 6 size can reduce skin irritation and improve patient comfort, especially when frequent dressing changes are required.

[0032] In a preferred embodiment, the inner layer 1 is rectangular, with a length greater than 10cm and a width greater than 8cm; this size effectively covers most of the disinfection area, reducing the risk of contamination. The upper protective layer 3 has a 1.5cm vertical tangent 7, and the lower protective layer 2 has a 0.5cm horizontal tangent 8. This allows medical staff to easily tear off the corresponding protective sheet 5 during operation while maintaining protection for other areas. It also makes it easy to tear the upper protective layer 3 or the lower protective layer 2 from the inner layer 1, reducing operation time and complexity.

[0033] When using it, open the sterile packaging of the auxiliary fixation dressing 100 and take out the dressing.

[0034] First, pass the extension tube of the puncture needle through the pre-reserved incision in a circular or other shape, hold the two folded sides of the lower protective layer 2 to expose the adhesive layer of the inner layer 1, and cover the skin surface with the inner layer 1 without tension.

[0035] The second step is to tear off the top protective page 5 in a circular motion starting from the pre-cut opening 4 at the bottom, while smoothing out the adhesive part on the outside with one hand to secure it properly.

[0036] The third step is to tear off the label 6 of the upper protective layer 3 from the horizontal cut, write the maintenance date on the paper tape on the right side of the protective page 5, and then tear it off from the pre-cut 4 and stick it on the inner layer 1 dressing.

[0037] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, including the combination of various specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
