Description

Technical Field

[0001] The utility model relates to the technical field of medical dressings, and more particularly to a dressing capable of measuring incision tension. Background Art

[0002] In current medical practice, the healing of surgical incisions is a complex and critical process that involves multiple factors, such as incision tension, infection control, nutritional support, etc. Among them, controlling incision tension plays a vital role in promoting healing and reducing complications.

[0003] The primary function of a dressing is to protect the wound, prevent infection, and promote wound healing. During this process, the dressing must possess excellent breathability, moisture absorption, and antibacterial properties to ensure a suitable healing environment for the wound. Furthermore, with the continuous advancement of medical technology, modern dressings are required to possess additional functions, such as hemostasis, pain relief, and tissue regeneration. Especially for anterior spinal surgery and thyroid surgery, early identification of changes in incision tension to prevent the formation of deep neck hematomas is crucial.

[0004] Existing dressings have obvious deficiencies in tension measurement. Existing dressing designs often ignore the real-time monitoring and regulation of incision tension. Doctors can usually only indirectly judge the tension of the incision by observing the appearance of the incision and the patient's symptoms. This method is not only inaccurate, but also unable to reflect changes in tension in a timely manner. Therefore, doctors often find it difficult to adjust treatment plans according to actual conditions, resulting in poor healing effects and even a series of complications. For example, in anterior cervical spine surgery or thyroid surgery, once a subcutaneous hematoma occurs, the swelling of the neck incision cannot be discovered in time, and the hematoma progresses and causes suffocation, seriously endangering the patient's life and health. Therefore, it is particularly important to develop a dressing that can measure incision tension.

[0005] Take silicone dressings as an example. Although they can protect wounds to a certain extent, due to the lack of tension measurement function, doctors often need to rely on experience to judge whether the dressing needs to be replaced or the fixation method needs to be adjusted. This subjective judgment often has errors and it is difficult to ensure the optimal healing environment for the wound. In addition, silicone dressings may age and fall off after long-term use, further increasing the difficulty of wound management. Although some researchers have proposed the use of pressure sensors to monitor incision tension in real time, these sensors are often bulky and expensive, and require additional equipment to read the data, which is not conducive to clinical promotion and use. Therefore, it is imperative to develop a dressing that can accurately measure incision tension and is convenient and practical.

[0006] In summary, the inadequacy of existing dressings in measuring tension has become a significant factor restricting wound healing and improving patient comfort. Therefore, a new dressing that can accurately measure incision tension is urgently needed to address this technical shortcoming and provide patients with a safer and more effective wound care solution.

[0030] Refer to the instruction manual Figure 1-4 The utility model provides a measurable incision tension dressing, comprising a dressing portion and a dressing substrate 1. The dressing substrate 1 is a polyurethane film. The polyurethane film has excellent elasticity and air permeability, ensuring that the dressing can provide sufficient pressure when it is attached to the wound, while keeping the skin around the wound breathable and comfortable, thereby facilitating wound healing and effectively reducing the risk of infection.

[0031] A dressing layer 6, an impermeable layer 8, and a medical adhesive layer 9 are fixed to the bottom of the dressing substrate 1. The dressing layer 6 is applied to the incision and is one of a calcium alginate dressing, a silver dressing, a hydrocolloid dressing, and a hydrogel dressing. The impermeable layer 8 is arranged on the outside of the dressing layer 6 to prevent leakage of incision exudate. The impermeable layer 8 is made of a water-absorbing resin. The medical adhesive layer 9 is arranged on the outside of the impermeable layer 8 for attachment to the skin next to the incision. A grid-shaped reinforcing tape 12 is attached to the top of the dressing substrate 1. The reinforcing tape 12 is arranged on top of the impermeable layer 8, and the portion of the reinforcing tape 12 extending from the dressing substrate 1 is attached to the skin next to the incision.

[0032] During use, the dressing layer 6 of the dressing part is applied to the incision, the anti-seepage layer 8 and the medical adhesive layer 9 are in contact with the skin next to the incision, and the dressing part is fixed to the skin by the medical adhesive layer 9. Then the part of the reinforcing tape 12 extending out of the dressing base material 1 is pasted on the skin.
