Abstract

The invention discloses a negative pressure drainage tube with the function of reducing skin tension. The negative pressure drainage tube comprises a negative pressure drainage tube body inserted intothe body of a patient, wherein an annular adhesive sticker attaches to the skin on the outer side of the negative pressure drainage tube body, a sponge ring sleeves the outer part of the negative pressure drainage tube body, an annular boss used for tightly pressing the sponge ring to the skin is arranged on the outer side wall of the negative pressure drainage tube body, a plurality of elastic cords which are distributed along the circumference are fixed on the circumference wall of the annular boss, a velcro tape sub fastener is fixed to the upper end face of the annular adhesive sticker, and velcro tape master fasteners for attaching to the velcro tape sub fastener are fixed on the lower end faces of the elastic cords. After the structure is adopted, under the effect of the elastic cords, the skin around the negative pressure drainage tube can be drawn to the position where the negative pressure drainage tube is located, thus the outward expansion of the skin can be avoided, and further, the occurrence of hypertrophic scars can be effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of medical devices and relates to a negative pressure drainage tube with the function of reducing skin tension. Background technique [0002] At present, after the negative pressure drainage tube is inserted into the patient's body, the skin at the negative pressure drainage tube will expand outward due to the tension of the skin. Hypertrophic scars are prone to appear in the skin tissue in the area. Contents of the invention [0003] In order to solve the above problems, the present invention designs a negative pressure drainage tube with the function of reducing skin tension, which can draw the skin around the negative pressure drainage tube to the position of the negative pressure drainage tube, so that the skin can be avoided External expansion can effectively avoid the appearance of hypertrophic scars. [0004] The purpose of the present invention is achieved like this: [0005] The negative pressu...
