Description

TECHNICAL FIELD

[0001] The application relates to the technical field of protective patches, in particular to a semi-permeable membrane protective patch. BACKGROUND

[0002] During the end-stage nursing of part of puncture ports, wounds or wounds, in order to isolate them from air and reduce the occurrence of infection, medical staff usually use patches to protect the puncture ports, wounds or wounds.

[0003] However, when part of the puncture ports, wounds or wounds are pressed or impacted, part of the blood will still flow out. The traditional patch does not have a channel for timely discharge of blood, so that the blood accumulates in the patch, causing the puncture port, wound or wound to ulcerate. Therefore, how to provide a protective patch that can timely discharge blood is an urgent problem to be solved by the staff.

[0004] However, when part of the puncture ports, wounds or wounds are pressed, impacted or in the healing process, part of the blood will still flow out. The traditional patch does not have a channel for timely discharge of blood, so that the blood accumulates in the patch, causing the puncture port, wound or wound to ulcerate. Therefore, providing a protective patch that can timely discharge blood is an urgent problem to be solved by the staff. CONTENT OF THE INVENTION

[0005] The application provides a semi-permeable membrane protective patch, which has the advantages of facilitating discharge of tissue fluid generated by the puncture port, wound or wound, and isolating the puncture port, wound or wound from the external environment.

[0006] The purpose of the utility model is realized by the following technical schemes:

[0007] A semi-permeable membrane protective patch, comprising a patch body and a liquid absorbing portion for absorbing tissue fluid, wherein the liquid absorbing portion is arranged around the outer side of the patch body; the side of the patch body that is attached to the skin is provided with a convex rib, and a gap for blood outflow is formed between the convex rib and the skin.

[0008] Preferably, the patch body is made of PU material.

[0009] Preferably, the side of the patch body that is attached to the skin is provided with an attachment convex portion, and the cross section of the attachment convex portion is arc-shaped.

[0010] Preferably, the connection between the attachment convex portion and the patch body is rounded.

[0011] Preferably, the number of convex ribs is four, and the four convex ribs are arranged around the attachment convex portion.

[0012] Preferably, the side of the patch body that is attached to the skin is provided with a protective patch.

[0013] Preferably, the liquid absorbing portion is made of cotton material.

[0014] Compared with the prior art, the technical scheme of the present application has the advantages or beneficial effects including:

[0015] 1. When the user covers the patch on the puncture, wound or wound surface, tissue fluid will flow out along the small gap between the convex ribs and the skin, thereby avoiding the accumulation of tissue fluid in the puncture, wound or wound surface, leading to ulceration.

[0016] 2. After the tissue fluid flows out along the small gap between the convex ribs and the skin, it can be absorbed by the liquid absorbing portion arranged around the outside of the patch body, avoiding the pollution of clothes or living environment after the tissue fluid flows out.

[0022] The embodiments of the present application will be described in detail below with reference to the accompanying drawings and examples, so that the implementation process of how to apply technical means to solve technical problems and achieve corresponding technical effects can be fully understood and implemented. The embodiments of the present application and each feature in the examples can be combined with each other without conflict, and the formed technical scheme is within the protection scope of the present application.

[0023] It should be clear that the following described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application. Embodiment 1

[0024] As Figures 1-3As shown, a semi-permeable membrane protective patch includes a patch body and a liquid absorbing portion 3 for absorbing tissue fluid, and the liquid absorbing portion 3 is arranged around the outer side of the patch body; the side of the patch body adhering to the skin is provided with a convex rib 4, and the convex rib 4 and the skin form a gap for blood and water to flow out.

[0025] When tissue fluid is generated at the puncture, wound or wound surface, the tissue fluid can flow out along the gap between the convex rib 4 and the skin surface until it is absorbed by the liquid absorbing portion 3. The patch body itself is made of PU material, and when the tissue fluid is discharged, the PU patch and the skin are dry, and the PU patch can further adhere to the skin, thereby playing a protective role for the wound again.

[0026] As shown in the figure, Figure 2 the side of the patch body adhering to the skin is provided with an adhering convex portion 5, and the cross section of the adhering convex portion 5 is arc-shaped.

[0027] The cross section of the adhering convex portion 5 is arc-shaped, which is more conducive to the discharge of tissue fluid to the periphery of the puncture, wound or wound surface, thereby avoiding the accumulation of tissue fluid in the puncture, wound or wound surface, and can maintain the dryness of the periphery of the puncture, wound or wound surface to a greater extent.

[0028] In this embodiment, the adhering convex portion 5 is provided with a rounded corner at the connection with the patch body.

[0029] As shown in the figure, Figure 2 the number of convex ribs 4 is four, and the four convex ribs 4 are arranged around the adhering convex portion 5. The four convex ribs 4 are conducive to the discharge of tissue fluid from the four sides of the adhering convex portion 5, and can accelerate the discharge efficiency of tissue fluid.

[0030] In this embodiment, the side of the patch body adhering to the skin is provided with a protective patch 1, 2.

[0031] In this embodiment, the liquid absorbing portion 3 is made of cotton material. The cotton material has better absorption effect on tissue fluid, and is less likely to cause skin diseases, and is safer to use. Embodiment 2

[0032] As shown in the figure, Figure 4 the number of convex ribs 4 is multiple and staggered. In order to let the blood and water of the puncture, wound or wound surface flow out, the convex ribs 4 are arranged in different heights, and the blood and water will flow out along the water guiding gap. The side of the convex rib with higher height in contact with the skin is provided with a pressure-sensitive adhesive, and the pressure-sensitive adhesive has the advantage of recovering adhesion after the blood and water dry.

[0033] The surface layer of the adhering convex portion 5 can be provided with antibacterial drugs, such as Ag ion antibacterial or drug antibacterial, etc. Figure 4As shown as an example, the convex part 5 is also provided with a grid-shaped convex rib, and the entire skin contact surface is coated with pressure-sensitive adhesive and antibacterial drugs (or: the convex rib can also have pressure-sensitive adhesive, or the concave surface can have pressure-sensitive adhesive), so that the blood and water can be discharged while further inhibiting wound infection.

[0034] In practical application, the protective dressing is divided into a remaining needle type and a surgical membrane type. Among them, the structure of the added liquid suction part 3 is mainly applied to the surgical membrane type.

[0035] At the same time, in order to increase the air permeability to a greater extent, a plurality of air permeable holes can be provided on the dressing body. The dressing body is made of PU material.
