In addition, for the convenience of use, a marking window 9 can be arranged on the anti-adhesive surface of the transparent dressing 1.
The sealing sleeve 2 is positioned on the anti-sticking surface side of the transparent dressing 1; specifically, the sealing sleeve 2 is a flexible sleeve structure which is adaptively connected to the opening 8, the inner diameter of the sealing sleeve 2 is consistent with the aperture of the opening 8, and the sealing sleeve is fixedly connected to the opening edge of the opening 8 in a sealing manner, so that the intravenous catheter passing through the opening 8 can penetrate out of the sealing sleeve 2. In addition, the sealing sleeve 2 has flexibility and can be downwards bent along with the intravenous catheter, so that the outer ends of the sealing sleeve 2 can be overlapped together to form the sealing of the port while the intravenous catheter is ensured to penetrate out of the sealing sleeve 2.
The sealing film 3 is of a rectangular structure, the middle part of one long side of the sealing film is fixedly connected to the outer end of the sealing sleeve 2 in a lap joint mode, and the length of the sealing film 3 extending out of the sealing sleeve 2 is ensured to cover the outer end of the sealing sleeve 2 which are overlapped together. In addition, an adhesive layer is further disposed on the sealing film 3 on the side connected with the sealing sleeve 2 (i.e. on the lower surface of the sealing film 2 in fig. 2), so that the outer end of the sealing sleeve 2 which is folded downwards and overlapped can be adhered to the transparent dressing 1 together with the penetrated intravenous catheter, thereby realizing the fixation and effective sealing of the outer end of the sealing sleeve 2.
The first support ring 4 is fixed on the wall of the opening 8, and a first annular groove 10 (shown in fig. 3) is formed on the inner annular surface of the first support ring 4 along the circumferential direction. The second support ring 5 is concentrically disposed inside the first support ring 4, so that an annular gap 11 (shown in fig. 2) is formed between the first support ring 4 and the second support ring 5; meanwhile, a connecting arm 12 fixedly connected with the first support ring 4 is also arranged on the second support ring 5, so that the first support ring 4 and the second support ring 5 are connected into a whole through the connecting arm 12; in addition, a second annular groove 13 (as shown in fig. 3) corresponding to the first annular groove 10 is formed on the outer annular surface of the second support ring 5 along the circumferential direction, and the notch of the first annular groove 10 is opposite to the notch of the second annular groove 13, so as to form a clamping cavity.
