Description

Technical Field

[0001] The utility model relates to the technical field of medical products, and more specifically, to a medical tape. Background Art

[0002] Currently, the commonly used medical adhesive tape products on the market are based on non-woven fabrics and non-woven cloths. They are mainly used to fix the infusion tube during infusion or fix the gauze during wound dressing. Since they are made of cloth materials, they have a high absorption rate of glue, large adhesion, and waste materials; scissors are required for use, resulting in low work efficiency; due to strong viscosity and strong adhesion to the skin, it causes pain to the patient when removed; the main structure of the medical tape is to coat glue on a base layer to achieve the effect of adhering to the skin of the injured person. Since the adhered part of the medical tape is not breathable, it is easy to cause phenomena such as flushing, itching, and allergy, and even cause the skin to turn white, wrinkle, and easily breed bacteria, resulting in wound inflammation and difficult wound healing. Content of the Utility Model

[0003] To achieve the above object, the utility model provides the following technical solution: a medical tape, including a tape body, characterized in that: the tape body includes a base layer, a glue layer, an anti-sticking layer, and a support layer; the support layer is a mesh structure composed of several strip-shaped fibers parallel to the two side edges of the tape body horizontally and several strip-shaped fibers perpendicular to the two side edges of the tape body vertically. Cut groups are arranged in the support layer grids along the extension direction of the two side edges of the tape body, and the cut groups are formed by diamond-shaped cuts penetrating the tape body; a plurality of ventilation holes are opened on the tape body, and the ventilation holes are arranged in a rectangular array.

[0004] The utility model is further arranged as: the glue layer is a silica gel layer. The glue layer is arranged in a dislocation manner with the ventilation holes.

[0005] The utility model is further arranged as: the ventilation holes are diamonds with arc-shaped edges.

[0006] The utility model is further arranged as: the anti-sticking layer is an EVA hot melt adhesive coated on the surface.

[0007] The utility model is further arranged as: the support layer is a bamboo fiber layer.

[0008] The utility model is further arranged as: the base layer is mulberry paper.

[0009] In summary, the utility model has the following beneficial effects: The novel can be easily torn through the arrangement of the cut group and the ventilation holes. The support layer can provide sufficient tensile strength to adapt to various occasions. Since the glue layer is silica gel, there are fewer adverse reactions when pasted, and it will not cause pain to the patient when removed. The glue layer 13 is arranged in a dislocation manner with the ventilation holes 3, so that the function of the ventilation holes 3 is not affected by the glue layer, and a good ventilation effect is obtained.

[0014] The present invention will be further described in detail below with reference to the accompanying drawings.

[0015] This embodiment discloses a medical tape, as Figure 2 shown, the tape body 1 includes a base layer 11, an adhesive layer 13, an anti-sticking layer 12, and a support layer 14. The base layer 11 is made of mulberry paper, which has good elasticity, good air permeability, and the advantage of being easily torn. The adhesive layer 13 is made of silicone, which is soft, thin, non-toxic, non-irritating, and non-allergic to the skin. When attached to the skin, it has the characteristics of softness, being stretchable, and good adhesion. Its adhesiveness is smaller than that of traditional materials, which can avoid the pain experience brought to patients when removing. The anti-sticking layer 12 is an EVA hot melt adhesive coated on the surface, which has excellent flexibility and stability. The support layer 14 is a bamboo fiber layer. Bamboo fiber is a cellulose fiber extracted from naturally grown bamboo. Bamboo raw fiber has good air permeability and good stretchability.

[0016] As Figure 1As shown, it includes a medical tape, wherein the support layer 14 is a mesh structure composed of several strip-shaped fibers parallel to the edges of both sides of the tape body 1 and several strip-shaped fibers perpendicular to the edges of both sides of the tape body 1. A cut group 2 is provided in the grid of the support layer 14 along the extension direction of the edges on both sides of the tape body 1. The cut group 2 is formed by diamond-shaped cuts 21 penetrating the tape body 1. The cuts 21 are small straight lines perpendicular to the edges of the tape body 1, so that the tape body 1 can be broken when subjected to a torsional tangential force. The diamond-shaped cuts 21 reduce the length of a single cut 21, so that when the tape body 1 is subjected to a torsional force, the cuts 21 can be broken and the fracture can be transferred to the next small notch, so that it can withstand a relatively high force along the direction of the tape without easily breaking without affecting the torsional fracture; a plurality of air holes 3 are provided on the tape body 1, and the tape can obtain better air permeability through the air holes 3. The air holes 3 are arranged in a rectangular array, which can well receive and transfer the fracture transmitted by the small cracks on the edge so that the fracture can be smoother.

[0017] like Figure 3 As shown, the mesh structure of the support layer 14 is wide in both the horizontal and vertical directions, so that the tensile strength of the tape body 1 is enhanced, and it can have sufficient strength to be used in medical processes, such as compressing hemostatic cotton. And when the fracture is transmitted, the longitudinal structure of the support layer 14 perpendicular to the tape body can play a guiding role, so that the fracture of the torn tape can be relatively flat.

[0018] Further improvement, the ventilation hole 3 is a rhombus with arc edges. The rhombus with arc edges has the advantage of being easier to tear than the circle, and the direction of the break is easier to control; the rhombus with arc edges has a larger area than the straight-edge rhombus, and can obtain better air permeability. The adhesive layer 13 and the ventilation hole 3 are staggered, so that the function of the ventilation hole 3 is not affected by the adhesive layer, and a good ventilation effect is obtained.

[0019] Working principle of the utility model

[0020] When in use, take out the rolled-up utility model and take out the required length. Because of the relationship between the incision group 2 and the air vent 3, it can be easily torn directly at the required position by shearing and twisting, and the removed tape can be attached to the patient's required position. Since the adhesive layer 13 is a silicone layer, the patient will not have too many adverse reactions when using it, and there will be no pain experience when removing it.

[0021] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
