[0002] Wound bandaging after excision of body surface infection (abscess, carbuncle, sebaceous cyst with infection, etc.) is an important step in clinical treatment. Infected wounds are mostly open wounds after surgery, and the wound area is large, inflammatory exudate is much, bleeding is easy, and dressings are easy to shift, which may lead to local wound infection, bleeding, and rash. Pressure dressing is the main and effective treatment method.
[0003] However, the bandaging dressings commonly used in clinical practice are difficult to meet their needs. There are mainly the following problems: 1. The sites of body surface infection are diverse, and are commonly found in the armpits, neck, shoulders, back, waist, buttocks and other parts. The local blood supply is rich, sweating is easy, and there is frequent activity. The infection in these parts is mostly open wounds after resection. At this time, the bandaging of the wound needs to effectively reduce exudation and facilitate smooth drainage. However, most of the dressings on the market are difficult to meet this requirement. 2. Dressing fixation. Due to the large wound area of the wound after surgery for body surface infection, local bleeding is easy, and the bandaging site is not easy to fix, the wound dressing needs to be not only easy to fix and breathable, but also has a certain pressure and does not fall off with the patient's limb movement, so that the local wound can be pressurized and bandaged to achieve the purpose of closing the wound and stopping bleeding. However, the current medical dressings are also difficult to meet this requirement. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] like Figure 1 and Figure 2 As shown, the utility model provides a self-adhesive elastic medical pressure dressing patch, comprising an elastic bandage 1, gauze 2, an oily dressing 3 and a release paper layer 4 arranged from top to bottom, wherein the elastic bandage 1 covers the gauze 2, the gauze 2 covers the oily dressing 3, an adhesive layer 6 is provided on the inner edge of the elastic bandage 1, the release paper layer 4 is the same size as the elastic bandage 1, the edges of the two are adhered to each other to form a sealed space, and the gauze 2 and the oily dressing 3 are wrapped inside; the oily dressing 3 is in direct contact with the injured part; the gauze 2 is a multi-layer gauze 2, and an air cushion 5 is provided between the gauze 2.
[0027] Normally, the oily dressing 3 selects oil gauze, which is about 5*5cm in size. It is a sterile, oily dressing that can be directly applied to the wound and has astringent properties; the gauze is a multi-layer flat sterile gauze block, which is about 5*cm in size. It is a sterile, dry dressing that is in direct contact with the oil gauze, has a certain air permeability, and is easy to absorb exudate; the elastic bandage is about 10*10cm in size, has the characteristics of elasticity, is in contact with the middle layer of gauze, is tightened and straightened, and is directly applied to the gauze under pressure. The adhesive layer is easy to stick and fix on the skin; various sizes of auxiliary materials can be designed to be suitable for wounds of different sizes.
[0028] Under normal conditions, the elasticity of an elastic bandage will weaken when it is stretched for a long time, which is equivalent to the pressure exerted by the elastic bandage on the dressing will weaken until it disappears completely. In this state, the elastic bandage cannot exert pressure on the dressing. Therefore, an air cushion is added to the gauze layer to further exert pressure on the wound surface. The air cushion is mainly set in the center area of the wound surface, and it can also reduce the pain caused by external objects on the wound surface.
[0029] like Figure 4 As shown, the present application provides a specific implementation of the air cushion, in which the air cushion 5 is divided into multiple air bags by an imprint 51, including a main air bag 52 arranged in the middle position and an auxiliary air bag 53 surrounding the main air bag 52. Multiple air bags are arranged, each air bag corresponds to a pressure point, and multiple force points cover the entire wound surface, so that the pressurization effect of the dressing is better.
[0030] Furthermore, the inflation volume of the main airbag 52 and the auxiliary airbag 53 is 70%-90% of the corresponding airbag capacity, so that the entire air cushion can be deformed under the action of external force, resulting in changes in the stress points, making the stress points more evenly distributed, thereby improving the effect of pressurizing the dressing, and is also suitable for the active parts of the human body and the needs of activities.
[0031] Furthermore, the main airbag 52 and the auxiliary airbag 53 are interconnected, so that the entire air cushion changes as a whole with the change of external force, and fits the wound surface more closely in the active state, thereby making the auxiliary material fit the wound surface more closely under the action of pressure to avoid wrinkles.
[0032] Furthermore, the air cushion 5 is provided with air holes 54 at the position of the imprint 51 to improve the air permeability of the air cushion.
[0033] The elastic bandage 1, gauze 2 and oily dressing 3 are independent of each other; the positional relationship among the oily dressing 3, gauze 2 and elastic bandage 1 can be adjusted according to the specific conditions of the wound surface. During nursing, medical staff can adjust the positions of the oily dressing and the gauze relative to the wound surface. For example, the gauze of the gauze layer can be overlapped with each other to expand the coverage area and better cover the wound surface; isolation paper is provided between the oily dressing 3 and the gauze 2. In this application, the oily dressing selects oil gauze. In order to prevent the oily position of the oil gauze from penetrating into the gauze, isolation paper is provided between the two for isolation.
[0034] like Figure 3 As shown, the present application also shows another embodiment of the pressurized dressing patch, in which the elastic bandage 1 extends outward on all sides to form an auxiliary elastic bandage 7, and the auxiliary elastic bandage 7 is arranged in a cross shape. The auxiliary elastic bandage 7 is provided with an adhesive layer 6, which is adhered to a release paper layer 4; when the wound surface is large and the gauze needs to be superimposed on each other to expand the coverage range, the elastic bandage will be unable to effectively cover the gauze, and then the auxiliary elastic bandage is used to adhere to the skin, thereby fixing the dressing.
[0035] Figure 5Another embodiment of a pressurized dressing is shown, comprising an elastic bandage 1, gauze 2, an oily dressing 3 and a release paper layer 4 arranged from top to bottom, wherein the elastic bandage 1 covers the gauze 2, the gauze 2 covers the oily dressing 3, an adhesive layer 6 is provided on the edge of the gauze on the inner side of the elastic bandage 1, the release paper layer 4 is the same size as the elastic bandage 1, the edges of the two are adhered to each other to form a sealed space, wrapping the gauze 2 and the oily dressing 3 inside; the gauze 2 is a multi-layer gauze 2, and an air cushion 5 is provided between the gauze 2. The elastic bandage is a long self-adhesive elastic bandage, which can be used to fix the wound surface. This fixation method is suitable for fixing dressings on movable parts of the human body, such as joints, shoulders, and cylindrical parts, such as arms and legs. The torso can also be fixed by wrapping it with a self-adhesive elastic bandage. Since the self-adhesive elastic bandage is wrapped for at least one week and then adheres to the bandage itself, the dressing is fixed more firmly and there is no need to worry about the dressing falling off.
[0036] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
