The positioning strip extends out of the sterile gauze, so that it is not attached to the sterile gauze. When the dressing patch is removed to the positioning strip, the positioning strip is separated from the dressing patch, so that the positioning strip can be pressed on the skin, thereby continuing to remove the dressing patch.

[0008] Further, the area of the dressing patch is greater than the area of the sterile gauze, and the edges of the sterile gauze are covered by the dressing patch. Thus, the firmness of the dressing patch when pasted on the skin is ensured, and the deep vein catheter can be stably fixed.

[0009] Further, the number of the positioning blocks is multiple, and the multiple positioning blocks are arranged at intervals along the edge of the sterile gauze. By pressing the multiple positioning blocks and the positioning strip, the dressing patch can be separated from the sterile gauze.

[0010] Further, the positioning block is arranged at the midpoint of the length direction edge of the sterile gauze. Thus, the length direction edge of the sterile gauze is pressed, and the dressing is facilitated to be peeled off from the sterile gauze.

[0011] Further, the positioning block is arranged at the midpoint of the length direction edge of the sterile gauze. Thus, the length direction edge of the sterile gauze is pressed, and the dressing is facilitated to be peeled off from the sterile gauze.

[0012] Further, the dressing is made of transparent material.

[0013] Further, the one side of the dressing is provided with an adhesive layer for bonding the sterile gauze and the peeling unit.

[0014] Further, the peeling unit is made of rubber material.

[0015] Further, the positioning block and the positioning strip are integrally formed.

[0016] The technical scheme provided by the present application can have the following beneficial effects: when the dressing needs to be replaced, the dressing is peeled from one side corner edge, when the dressing is peeled to the sterile gauze, the positioning strip extends from the edge of the sterile gauze, the positioning strip is pressed first, the peeling unit is separated from the dressing, when the dressing is peeled to the positioning block, the positioning block is pressed by the finger, the sterile gauze is pressed, and the dressing is peeled from the sterile gauze. Thus, the sterile gauze is prevented from being peeled together with the dressing, the skin around the deep vein catheter is prevented from being pulled, the local damage of the puncture point and the fixed catheter suture point is prevented, and the infection risk is reduced. If the sterile gauze needs to be replaced, the sterile gauze is slowly taken down after the dressing is completely peeled, so that the sterile gauze is prevented from being peeled together with the dressing, and the patient is prevented from being stimulated and damaged due to the adhesion of the sterile gauze to the epidermis.

[0028] As shown in Figure 1 and Figure 2 The protective unit 200 includes sterile gauze 210 covering the deep vein catheter 100, and a dressing patch 220 covering the sterile gauze 210 and being bonded.

[0029] The sterile gauze 210 can protect the puncture site and reduce bacterial infection, and the dressing patch 220 can fix and limit the sterile gauze 210 and the deep vein catheter 100.

[0030] The dressing patch 220 is made of transparent waterproof material, and the transparent setting of the dressing patch 220 can facilitate observation of the condition around the sterile gauze 210 and check whether bleeding occurs, etc., so as to facilitate adjustment, and the dressing patch 220 can prevent liquid from directly falling on the puncture site from the outside, thereby playing a waterproof role and preventing infection from water.

[0031] The upper surface area of the sterile gauze 210 is greater than that of the deep vein catheter 100, and the upper surface area of the dressing patch 220 is greater than that of the sterile gauze 210, so that the dressing patch 220 can completely cover the sterile gauze 210, and the sterile gauze 210 can fully protect the deep vein catheter 100, and the dressing patch 220 can further play a protective role.

[0032] As shown in Figure 1 and Figure 2 In some embodiments, the removal unit 300 includes a positioning block 310 arranged between the sterile gauze 210 and the dressing patch 220, and a positioning strip 320 is integrally formed on the side wall of the positioning block 310, and the positioning strip 320 extends out of the edge of the sterile gauze 210 from the positioning block 310.

[0033] The positioning block 310 and the positioning strip 320 can determine the pressing position and prevent direct pressing on the deep vein catheter 100 or the puncture port, and the positioning block 310 and the positioning strip 320 are made of rubber, which facilitates bonding with the dressing patch 220 and has a certain deformation ability, can be flattened and positioned in the protective unit 200, and will not be too protruding or too hard to cause skin discomfort.

[0034] In some embodiments, the sterile gauze 210 is provided with four removal units 300 at the four corners and the middle points of the two length directions of the edges of the sterile gauze 210.

[0035] The removal units 300 are arranged between the sterile gauze 210 and the dressing tape 220, and the positioning strips 320 are inclined outwardly at the four corners of the sterile gauze 210 to lift the dressing tape 220 from the corner edges. When the dressing tape 220 is lifted to the sterile gauze 210, the positioning strips 320 extend out of the edges of the sterile gauze 210, and pressing on the positioning strips 320 can apply pressure to the sterile gauze 210 to lift the dressing tape 220. The removal units 300 are arranged to be adhered to the dressing tape 220 after being placed, and the removal units 300 can be conveniently disassembled.

[0036] When the dressing tape 220 needs to be replaced, the dressing tape 220 is lifted from one side corner edge, and when the dressing tape 220 is lifted to the sterile gauze 210, the positioning strips 320 extend out of the edges of the sterile gauze 210. The positioning strips 320 can be pressed first to separate the removal units 300 from the dressing tape 220. When the dressing tape 220 is lifted to the positioning blocks 310, the fingers can press on the positioning blocks 310 to apply pressure to the sterile gauze 210, so that the dressing tape 220 can be lifted from the sterile gauze 210. In this way, the sterile gauze 210 can be prevented from being lifted together with the dressing tape 220 when the dressing tape 220 is lifted, so that the skin around the deep venous catheter 100 under the sterile gauze 210 is prevented from being pulled, local damage at the puncture point and the catheter fixation suture point is prevented, and the risk of infection is reduced. If the sterile gauze 210 needs to be replaced, the sterile gauze 210 is slowly removed after the dressing tape 220 is completely lifted to avoid irritating and damaging the patient due to adhesion of the sterile gauze 210 to the epidermis when the sterile gauze 210 is lifted together with the dressing tape 220.
