Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, and particularly relates to a dressing protection band. Background Art
[0002] A wound dressing is a material used to cover sores, wounds or other injuries, mainly used to help the early healing of postoperative wounds. Using a wound dressing can effectively isolate bacteria, viruses and other microorganisms in the outside world and prevent them from contaminating the wound. At the same time, after lumbar spine, hip joint, knee joint replacement, and femoral shaft and tibiofibular fractures surgeries, wound drainage tubes are usually left in place to prevent the accumulation of fluid and gas during the operation from affecting wound healing. However, in clinical practice, it has been found that many patients who have undergone lumbar spine, hip joint, knee joint replacement, and femoral shaft and tibiofibular fractures surgeries often cause the wound dressing to fall off or shift due to reasons such as bed activities, getting out of bed activities, turning over, or delirium. This situation will expose the wound to the external environment, increasing the risk of infection. Especially in the early postoperative stage, when the wound has not fully healed, an unstable dressing will hinder normal healing, affecting the patient's comfort and the rehabilitation process. In addition, frequent dressing changes not only increase the workload of medical staff, but also consume a large amount of medical resources and increase the treatment cost. In view of this, it is particularly important to study and improve the existing problems to solve the problems of dressing falling off and shifting, and to design a dressing protection band.

Obviously, the described embodiments are some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0024] Please refer to Figures 1 to 4 , this embodiment provides a dressing protection band, including a protection band body 1; and a fixing device 2 provided on the protection band body 1, the fixing device 2 is used to fixedly cover the dressing with the protection band body 1; the fixing device 2 includes a connecting piece 21, and both ends of the protection band body 1 are releasably joined through the connecting piece 21; a drainage tube through hole 3 is further provided on the protection band body 1, and a clamping seat 4 is provided in cooperation with the drainage tube through hole 3 for fixing the drainage tube 5 to reduce the risk of unplanned extubation.
[0025] When the dressing protection band provided in this embodiment is used, the side of the protection band body 1 away from the clamping seat 4 is directly arranged on the side of the dressing away from the human body. The position of the protection band body 1 is restricted by the fixing device 2, and the protection band body 1 is fixed to the human body through the connecting member 21, so that the protection band body 1 is fixedly covered on the dressing, achieving the situation of protecting the dressing and preventing the dressing at the wound from falling off, thereby protecting the wound. Through this setting, it restricts the increase of wound tension, prevents the wound from tearing and splitting, as well as the movement wrinkles of the wound skin and / or makes the wound open outward.
[0026] In this embodiment, the protection band body 1 is medical cotton cloth or gauze widely used in the medical environment, which is not likely to cause allergies or irritation, can provide a comfortable use experience, and reduce the discomfort of patients. It should be noted that the dressing protection band provided in this application can be used not only for protecting the wound dressings of patients after orthopedic thoracolumbar spine, hip and knee joint replacement, and tibiofibular fracture surgeries, but also for other surgeries in the chest and abdomen (such as thoracotomy and laparotomy).
[0027] Specifically, the dressing protection band provided in this application can be adjusted according to the position of the dressing, including adjusting the size and shape of the protection band body 1 according to the position of the dressing. For reference, in this embodiment, the protection band body 1 takes a rectangle as an example. When the dressing protection band is used to protect the dressing in the chest and waist, the protection band body 1 includes three specifications: 35 cm (length) × 30 cm (width), 40 cm (length) × 30 cm (width), and 45 cm (length) × 30 cm (width). When the dressing protection band is used to protect the dressing on the thigh, the dressing protection band includes three specifications: 10 cm (length) × 30 cm (width), 15 cm (length) × 40 cm (width), and 20 cm (length) × 50 cm (width). When the dressing protection band is used to protect the dressing for the calf and knee, the dressing protection band includes three specifications: 10 cm (length) × 30 cm (width), 15 cm (length) × 35 cm (width), and 20 cm (length) × 45 cm (width). It can be understood that providing these different specifications of protection band sizes is to better adapt to the wound dressings in different parts and provide more personalized protection needs.
[0028] As a preferred embodiment, the fixing device 2 further includes elastic bands 22 connected to both ends of the protection band; the connecting member 21 includes a first fixing element 211 and a second fixing element 212 connected to the elastic band 22; both ends of the protection band body 1 are connected by the cooperation of the first fixing element 211 and the second fixing element 212. With this structure, even if the patient's body becomes thicker after the wound dressing is bandaged, the appropriate tightness can still be maintained through the elastic bands, improving the flexibility and practicality of the dressing protection band.
[0029] Furthermore, the first fixing element 211 and the second fixing element 212 are respectively provided with the hook surface and the loop surface of the Velcro, and both ends of the protection belt body 1 are connected by the cooperation of the hook surface and the loop surface of the Velcro; the hook surface and the loop surface of the Velcro can provide a firm fixing effect to ensure that the protection belt will not accidentally loosen or move during use. This is crucial for the safety and stability of the protection belt body 1, especially when there are many activities or when it needs to be worn for a long time. With this structure, the connecting member 21 can be adjusted and fixed quickly and simply. Just align the hook surface and the loop surface to securely fix the protection belt; in some embodiments of the present application, the first fixing element 211 and the second fixing element 212 can also be fixed by a buckle.
[0030] As a preferred embodiment, the clamping seat 4 includes a fixing seat 41 provided on the protection belt body 1 and an end cover 42 threadedly engaged with the fixing seat 41. An elastic snap ring 43 is provided between the end cover 42 and the fixing seat 41. The elastic snap ring 43 is used to clamp the drainage tube 5 to ensure that the drainage tube 5 will not accidentally fall off or move during use. The end cover 42 and the fixing seat 41 are detachably engaged by a threaded connection, so that the clamping seat 4 can be easily installed and removed for daily maintenance, cleaning or replacement of components, reducing the complexity and time cost of operation. In some embodiments of the present application, the end cover 42 and the fixing seat 41 can also be fixed by a buckle or a tenon. In addition, the elastic snap ring 43 is used to clamp and fix the drainage tube 5 to facilitate the fixing requirements of drainage tubes 5 with different cross-sectional shapes.
[0031] As a preferred embodiment, a tapered surface 421 is formed on the inner wall of the end cover 42. When the end cover 42 is engaged with the fixing seat 41, the tapered surface 421 abuts against the end of the elastic snap ring 43 to drive the elastic snap ring 43 to clamp the drainage tube 5. In this structure, the design of the tapered surface 421 enables the tapered surface 421 to gradually contact and gradually squeeze the elastic snap ring 43 when the end cover 42 and the fixing seat 41 are threadedly connected, causing the elastic snap ring 43 to deform radially, thereby clamping the drainage tube 5 more tightly and preventing the drainage tube 5 from accidentally moving or falling off during use, reducing the risk of loosening of the drainage tube 5.
[0032] Furthermore, the elastic snap ring 43 includes an inner ring 431 that fits the outer diameter of the drainage tube 5 and an outer ring 432 that abuts against the end cover 42 and the fixing seat 41. The outer diameter of the outer ring 432 gradually increases from the end close to the fixing seat 41 to the end close to the tapered surface 421 to ensure that when the elastic snap ring 43 is abutted by the inner walls of the end cover 42 and the fixing seat 41, the pressure distribution received is more uniform, avoiding excessive local stress on the drainage tube 5.
[0033] Furthermore, the contact parts of the outer ring 432 with the end cap 42 and the fixed seat 41 are in smooth transition or chamfered to reduce the risk of stress concentration and improve the durability and service life of the elastic snap ring 43. The inner wall surface of the inner ring 431 is provided with anti-slip lines (not shown in the figure) to enhance the friction between the inner ring 431 of the elastic snap ring 43 and the drainage tube 5 and ensure a good clamping and fixing effect.
[0034] As a preferred embodiment, a water-absorbing layer 6 is further provided on the protection belt body 1. The water-absorbing layer 6 is arranged around the clamping seat 4, and the exudate penetrating through the dressing body is absorbed by the absorption layer to keep the dressing clean and dry. Furthermore, the water-absorbing layer 6 is replaceably attached to the protection belt body 1 by pasting. When replacement is needed, the water-absorbing layer 6 can be directly torn off and a new one can be replaced, without the need to replace the dressing protection belt as a whole, so as to reduce the inconvenience and residence time that may be caused during the replacement process and extend the service life of the dressing protection belt.
[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
