Embodiment 1

[0031] The present embodiment is a self-opening drainage type wound dressing, combined with image 3 and Figure 4 , comprising a backing layer 1, an elastic film 2 and a non-adhesive film layer 3, the elastic film 2 is fixed on the backing layer 1, and the elastic film 2 is provided with a knife edge 4, combined with Figure 5 , the knife edge 4 is arranged along the width direction of the elastic sheet film 2, and penetrates the backing layer 3, and the knife edge 4 is evenly distributed on the elastic sheet film 2 with multiple rows and columns to form the permeation zone 21, and the length of each knife edge 4 is 12mm, the row spacing is 3mm, and the column spacing is 1.5mm; the non-adhesive film layer 3 is provided with two pieces, which are respectively called non-adhesive film one 31 and non-adhesive film two 32, non-adhesive film one 31 and non-adhesive film two 32 intersect Overlaid on the elastic film 2. Wherein, the elastic film 2 is also provided with a hand-held...

Embodiment 2

[0038] The setting and working principle of this embodiment are the same as those of Embodiment 1, the difference is that the backing layer 1 is pre-treated with a primer, and then coated with silicone gel to dry and set, the silicone rubber film is used as the backing layer 1, and the knife edge 4 Through the elastic film 2 and the backing layer 1 , in this embodiment, the elastic film 2 and the elastic backing layer 1 are firmly combined together and cannot be easily separated.

Embodiment 3

[0040] The setting and working principle of this embodiment are the same as those of Embodiment 1, the difference is that the composition of the mixed silicone gel is composed of soft silicone viscose A and soft silicone viscose B, and the mass ratio of each component is 40%. : 60%, blend the above mixed silicone gel to make its viscosity reach 10000 mpa.s; use the gap control glue coating method to evenly coat the mixed silicone gel prepared in the previous step on the polyamide film, and the total thickness is controlled At 0.45mm, after heating in an oven at 90°C for 30 minutes, a silicone gel elastic film with a holding viscosity of 200 minutes (100g weight) is formed, wherein the silicone rubber film is the backing layer 1, and the mixed silicone gel forms the elastic film 2; Use a thin blade with a width of 10 mm to displace and cut through the gel membrane to form a transparent knife edge 4 with a width of 10 mm on the membrane. Only part of the position is on the same ...

Abstract

The invention relates to a self-opening drainage type dressing for a wound and a processing method thereof, and belongs to the technical field of medical supplies. The self-opening drainage type dressing for the wound comprises a backing layer, an elastic membrane and a cohesionless membrane layer, the elastic membrane is fixed on the backing layer and provided with knife edges which are formed in the width direction of the elastic membrane and penetrate through the backing layer, the knife edges are evenly distributed in the elastic membrane for multiple lines and rows in a staggered mode to form an infiltration area, the length of each knife edge ranges from 5 mm to 20 mm, the space between the lines ranges from 2 mm to 8 mm, and the space between the rows ranges from 1 mm to 5 mm; the cohesionless membrane layer is provided with two pieces, and the two pieces of the cohesionless membrane layer overlay on the elastic membrane in a cross mode. The self-opening drainage type dressing for the wound and the processing method thereof are applied to clinical applications and have the advantages of being capable of conducting automatic opening and drainage, high in safety, low in cost, convenient and fast to use and the like.

Description

technical field [0001] The invention relates to a self-opening drainage wound dressing and a processing method thereof, belonging to the technical field of medical supplies. Background technique [0002] At present, most of the exudate drainage dressings used internationally and domestically are mostly vaseline gauze (such as figure 1 As shown), it is composed of large-mesh absorbent cotton gauze 1a soaked with medical Vaseline oil. When used, it is covered on the wound, and the outer layer is covered with absorbent dressings, such as sterile gauze, absorbent cotton, medical dressing core, etc., and the exudate passes through the gauze The mesh 2a of the mesh seeps out and is absorbed by the outer absorbent dressing; this wound care method utilizes the water repellency of Vaseline and the permeability of the large mesh gauze 1a, which can make the wound discharge the exudate in a short time, thereby It will not impregnate the wound; its disadvantage is that it will cover th...
