[0015] The utility model will be further described below in combination with the drawings.
[0016] In order to make the utility model purposes, technical scheme and advantages more clear and clear, the following combines with the drawings and specific implementation, and the utility model is further detailed.The specific implementation described here is only used to explain the utility model, and is not used to limit the utility model.
[0017] Reference Figs. 1-3 A kind of device for promoting wound healing, including limit ring 1 and healing ring 2, both are oval structure;The inner circle of limit ring 1 is stepped structure, and limit groove (not shown in drawing) of annular structure is arranged in the step;Healing ring 2 includes outer ring 21, outer ring 21 is embedded into limit groove, and clearance fit between the two, and located in limit groove is rotated, and a pair of connecting strips 22 are arranged at the length direction both ends in outer ring 21, multiple oval structure elastic rings 23 are arranged between the outer side of connecting strip 22, and closing ring 24 is arranged on the opposite surface between connecting strip 22;When healing ring 2 is rotated from width direction of oval structure to length direction, outer ring 21 is stretched, that is, elastic ring 23 and closing ring 24 are stretched, so that the width of elastic ring 23 and closing ring 24 is reduced and closed.The utility model is glued on skin, and closing ring 24 is wrapped outside wound at the same time, at this time, outer ring 21 can be rotated, so that when outer ring 21 is rotated from width direction of oval structure to length direction, outer ring 21 is stretched, that is, elastic ring 23 and closing ring 24 are stretched, so that the width of elastic ring 23 and closing ring 24 is reduced and closed, micro stress is applied to wound area, the gap between wound area is reduced and controlled, and stress shielding is realized to wound area by the structure of outer side, the influence of stress and strain generated due to body movement and movement of other parts of body on healing tissue is reduced, and cell proliferation and tissue repair in wound healing stage are steadily carried out in a stable state.
[0018] The utility model discloses a material of elasticity and good biocompatibility is made, and the skin around the wound is closely combined, does not cause the discomfort of patient, and also is convenient for the activity of patient in daily life.
[0019] The utility model discloses through the following several aspects of function under proper pressure to promote wound healing:
[0020] 1. Reduce edema and exudation: by exerting uniform pressure on the wound periphery, limit the fluid exudation of local tissue, reduce the edema of the wound site. The reduction of edema helps to improve the blood circulation of local tissue, and provides a better environment for wound healing.
[0021] 2, promote tissue adhesion: continuous and stable pressure can make the tissue of wound edge closely adhere, reduce the gap of wound, promote the connection and healing process between cells. For example, for surgical incision and other wounds, the pressure regulating device can ensure that the tissues on both sides of the incision always maintain good contact, accelerate the closure of the wound.
[0022] 3, stimulate cell proliferation: a certain degree of pressure may stimulate the proliferation of cells around the wound, especially the key cells such as fibroblasts involved in wound repair. These cells accelerate the synthesis of extracellular matrix components such as collagen under the action of pressure, providing structural support for wound healing.
[0023] In this embodiment, the limiting ring 1 is preferably made of a material with good elasticity and biocompatibility to ensure that it closely adheres to the skin around the wound and does not cause allergy or other adverse reactions. At the same time, the material also needs to have certain strength and durability, which can keep the shape stable during use, and can withstand a certain pressure and friction, avoiding the deformation of the patient's body under the action of external forces such as pressure, friction and pulling, maintaining the stability of its shape and size. This is crucial to ensure the adhesion of the device to the wound and the treatment effect. If the shell material is easily deformed, it may cause uneven pressure distribution, unstable drug release and other problems, affecting wound healing. The material of the limiting ring 1 should also have high tear resistance, which can not be easily broken when subjected to accidental pulling or tearing force. For example, when the patient accidentally hooks the mechanical device or accidentally pulls the device when putting on or taking off clothes, the material with good tear resistance can avoid the shell from breaking, protecting the wound from further damage.
[0024] In this embodiment, the healing ring 2 needs high-precision manufacturing process to ensure its stable and reliable performance. The manufacture of these miniaturized and high-precision components requires high technology and equipment; the healing ring 2 is preferably made of medical silicone, polyurethane, polytetrafluoroethylene and other materials.
[0025] In this embodiment, the inner circle of the outer ring 21 is exposed to the limiting groove, which is beneficial to the rotation operation of the outer ring 21, that is, to the opening and closing of the healing ring 2.
[0026] In this embodiment, the elastic ring 23 and the outer side of the closing ring 24 are provided with a plurality of contact blocks 25. The contact blocks 25 are used to increase the contact area with the skin, thereby improving the firmness of the adhesion.
[0027] In this embodiment, the healing ring 2 is integrally formed, which is convenient for production and processing.
[0028] The above description is only used to illustrate the technical scheme of the present application, but not limit it. Other modifications or equivalent replacements to the technical scheme of the present application made by those skilled in the art should be covered in the scope of the claims of the present application, as long as they do not deviate from the spirit and scope of the present application.
