Protecting and fixing device for wound

Abstract

The invention discloses a protecting and fixing device for wound, comprising at least one protecting and fixing layer with openings, wherein the protecting and fixing layer with openings is longitudinally provided with an opening for communicating the upper end face and the lower end face; the opening can enclose the wound therein so as to make the protecting and fixing layer with openings limit the wound tension and increase the mobile corrugation of the wounded skin. The invention can protect and fix the operation wound, the trauma wound or the catheter infusion wound into an opening which can limit the tension increase of the wound and the mobile corrugation of the surface skin of the wound and can prevent the wound from being torn and cracked and also avoid the damage for the wound due to the mobile corrugation and the surgical dressing of the wounded skin as well as the relative displacement frictions of the infusion catheter. Therefore, the invention fills the blank of current technology, which can enable the covered dressings to penetratively contact the secretion so as to absorb the exudate of the wound. Besides, the invention can prevent the foreign material contact anaphylaxis due to the wound contacting by compressing the dressing and the direct bonding of the catheter infusion wound and can prevent the re-injury of the wound caused by the synechia between the dressing and the wound secretion.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a wound protection fixation device. Background technique [0002] People will be injured by many factors in their life and cause wounds, such as external wounds, surgical wounds and catheter infusion wounds. After encountering wounds, they must protect and care for the wounds to avoid wounds caused by wound infection. Severe complications, so excellent wound protection care technology and products are very important to accelerate wound healing. At present, in clinical medicine, wound protection and care are mainly carried out through the use of wound dressings. These products mainly include spunlace non-woven fabrics and transparent film dressings. , foam dressings, foam dressings, hydrocolloid dressings and functional dressings, etc., different types of dressings for different types of wounds can be used for protection and care to achieve better results.

AI Technical Summary

Problems solved by technology

[0007] 1. Because of its good flexibility, it can produce the same moving wrinkles along with the movement of the surface skin and cannot prevent the movement of the skin. Therefore, when the skin surface is moved by external force or body activity When wrinkled, the catheter will be displaced and damage the catheter infusion wound;

[0008] 2. The adhesive is pasted on the infusion wound, which will cause irritation of the wound and surrounding skin, and inflammatory reactions such as contact dermatitis;

[0009] 3. Impervious to sweat, sweat accumulates in the wound and under the film, which is easy to cause wound infection, secondary phlebitis or blood infection and other serious complications;

[0010] 4. It needs to be replaced within 3 to 6 days. If the dressing is not replaced for a longer period of time and the wound is disinfected, it will cause infection

[0016] 1. Opaque (hydrocolloid is translucent), so the changes of the wound cannot be observed at any time;

[0017] 2. Compared with the transparent film dressing, its flexibility and conformability are poor, and its rigidity and hardness are strong. It is easy to separate and fall off from the skin surface under the action of tension, so its fixation is also poor. When it is applied to the body that is prone to moving wrinkles Wounds on the active parts of the joints or easy to fall off and separate when sweating during exercise;

[0018] 3. Poor or non-waterproof, the adhesive layer of the dressing will easily separate from the skin when exposed to water;

However, its defect is that the fixed medical supplies or wounds protected by the fixed adhesive layer will be displaced and moved along with the moving folds on the skin surface. Catheter movement at the entrance and displacement of wound surface folds lead to wound re-injury and relative displacement and friction between the wound and the dressing to damage the wound tissue
