DETAILED DESCRIPTION

[0018] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments. Example 1

[0019] In order to achieve the effect of air permeability and waterproofness of foam tape, a medical foam tape is designed. The specific solution is as follows:

[0020] like Figure 1As shown, a medical foam tape comprises an upper foam layer 1 and a lower foam layer 2, air holes are provided between the upper foam layer 1 and the lower foam layer 2, the air holes comprise an upper air hole 101 provided on the upper foam layer 1 and a lower air hole 201 provided on the lower foam layer 2, the upper air hole 101 and the lower air hole 201 are staggered and partially connected, a water-absorbing layer 3 is provided between the upper foam layer 1 and the lower foam layer 2, the water-absorbing layer 3 is provided with communicating holes penetrating therethrough, and the communicating holes are connected with the upper air hole 101 and the lower air hole 201, a hydrophobic layer 4 is further provided on the upper surface of the upper foam layer 1 for rapid water repellency, and a release layer 6 is provided on the lower surface of the lower foam layer 2.

[0021] In this embodiment, the water-absorbing layer 3 is relatively thin, and the upper foam layer 1 and the lower foam layer 2 are relatively thick. In other schemes, the thickness of the water-absorbing layer 3 can be increased, and the thickness of the upper foam layer 1 and the lower foam layer 2 can be reduced.

[0022] The water absorbing layer 3 is made of polymer material, for example, water absorbing resin.

[0023] The upper foam layer 1 and the lower foam layer 2 are both PE foams.

[0024] A transparent protective layer 5 is also provided on the upper surface of the hydrophobic layer 4, and the protective layer is a tearable structure.

[0025] When the tape is used at home, bandages are rarely used, and similar products are generally idle. If the foam tape is idle for a long time, the surface may be covered with dust, and the dust may enter the ventilation holes. If the tape is used again, it may cause wound infection and other problems. Therefore, a tearable transparent protective layer 5 is provided to prevent dust from forming on the surface of the tape, especially at the ventilation holes. When the user uses the tape again, the surface of the tape can be kept clean.

[0026] Each vent hole corresponds to a through hole 301 , and the size of the through hole 301 is smaller than the size of the vent hole.

[0027] The main purpose is to make part of the water-absorbing layer 3 located in the air hole to block the water vapor, which is equivalent to the intersection of the two holes on the plane, making it more difficult for external water vapor to enter the lower air hole 201.

[0028] The upper end of the through hole 301 is located in the upper air hole 101 , and the lower end of the through hole 301 extends toward the lower air hole 201 and communicates with the top of the lower air hole 201 .

[0029] The cross-section of the through hole 301 is stepped, the lower end of the through hole 301 is large, the upper end is small, and the lower end of the through hole 301 is biased towards the lower air hole 201. Due to the structure of the through hole 301, an L-shaped connecting channel can be formed between the upper air hole 101 and the lower air hole 201.

[0030] The bottom of the portion where the through hole 301 is located is a concave structure to form a channel connecting the upper end and the lower end of the through hole 301 .

[0031] The hydrophobic layer 4 is further provided with a side protection layer 402 , and the side protection layer 402 is in contact with the side surfaces of the upper foam layer 1 , the water absorption layer 3 and the lower foam layer 2 .

[0032] The hydrophobic layer 4 is provided with outer holes 401 corresponding to the upper air holes 101 to ensure air permeability.

[0033] The foam tape of the present invention has a tearable transparent protective layer 5 on its surface, which can prevent dust from forming on the surface of the tape. A hydrophobic layer 4 is also provided on the upper layer of the tape to quickly remove surface water stains. In addition to covering the upper surface of the upper foam 1, the hydrophobic layer 4 also covers the sides of the upper foam 1, the water-absorbing layer 3, and the lower foam 2 to prevent water seepage on the sides, ensuring that the tape can still be firmly adhered after being wetted. Air holes are provided on the upper foam 1 and the lower foam 2, and the air hole structure is staggered to prevent water vapor from easily reaching the wound. A water-absorbing layer 3 is also provided between the upper foam 1 and the lower foam 2, which can be used to absorb water vapor taken in from the outside and moisture emitted from the pores to ensure that the wound is dry and not infected.

[0034] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
