Description

Technical Field

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

[0002] Medical tapes are medical devices widely used in the medical field, mainly used to paste and fix dressings on wounds or fix other medical devices to specific parts of the human body;

[0003] For example, a breathable and anti-allergic medical tape with the publication number CN218980173U. The cooperation between the tape main body and the shielding layer is used. When fixing the needle on the baby's head, after tearing off the tape main body, the shielding strip can be flipped under the tape main body according to actual fixing needs and pasted using the adhesive layer, so that when pasting and fixing, the adhesive layer is prevented from contacting the baby's hair, and the baby is prevented from crying due to great pain when tearing off; the cooperation between the sweat-absorbing layer and the color-developing layer is used. The sweat-absorbing layer can adsorb the sweat generated at the position where the tape adheres to the skin. Therefore, the color-developing layer arranged above the sweat-absorbing layer will change color when contacting sweat, thus reminding patients and medical staff that more sweat has been generated at the pasting position and the adhesiveness of the tape needs to be checked to avoid the situation of falling off due to the reduction of adhesiveness caused by sweat; the cooperation between the ventilation holes and the antibacterial layer is used. The uniformly arranged ventilation holes can improve the air permeability of the tape after pasting, thus preventing the skin from turning white due to poor air circulation, and the antibacterial layer can inhibit the large reproduction of surrounding bacteria, thus preventing the occurrence of bacterial allergies;

[0004] When the above technical solution is used, medical staff paste the tape main body on the patient's skin through the adhesive layer for use. However, when the medical staff removes the tape main body, the medical staff needs to first pick out a corner of the tape main body with their fingernails, and then quickly and violently tear it off to separate it from the patient's skin, resulting in the easy tearing off of the hair on the skin together, causing pain to the patient. At the same time, this method of removing the medical tape is relatively inconvenient.

[0005] Therefore, we propose that the medical tape can well solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a medical tape to solve the problem in the above background technique that when the medical staff removes the tape main body, the medical staff needs to first pick out a corner of the tape main body with their fingernails, and then quickly and violently tear it off to separate it from the patient's skin, resulting in the easy tearing off of the hair on the skin together, causing pain to the patient. At the same time, this method of removing the medical tape is relatively inconvenient.

[0007] To achieve the above object, the present utility model provides the following technical solutions: A medical tape, comprising a base layer, a paste layer is provided below the base layer, and a surface layer is provided above the base layer;

[0008] A medical tape further comprises:

[0009] A storage cavity is formed inside the base layer, a tear line is provided between the two base layers, an easy-to-tear member is connected to the corner of the upper surface of the base layer, and an air inlet hole is formed between the easy-to-tear member and the storage cavity;

[0010] An antibacterial layer is heat-sealed between the base layer and the paste layer, and elastic blocks are adhesively connected to the left and right sides inside the base layer.

[0011] Preferably, iron powder is stored inside the storage cavity, and the storage cavity and the air inlet hole are internally connected to each other. The bottom of the easy-to-tear member is hermetically connected to the top of the air inlet hole, and the corner of the outside of the easy-to-tear member is adhesively connected to the base layer. Moreover, tear lines are provided at the connection positions of the two sides of the easy-to-tear member and the base layer.

[0012] Preferably, the two elastic blocks are symmetrically distributed inside the base layer, which can improve the tensile property of the base layer.

[0013] Preferably, a breathable layer is heat-sealed to the upper surface of the base layer, a sweat-absorbing layer is heat-sealed to the upper surface of the breathable layer, air-permeable holes are formed inside the surface layer, and a color-developing layer is heat-sealed to the upper surface of the surface layer.

[0014] Preferably, multiple air-permeable holes are equidistantly distributed inside the surface layer, and the breathable layer is made of polyester fiber material.

[0015] Preferably, the sweat-absorbing layer is made of linen fiber material.

[0016] Preferably, turmeric powder is stored inside the color-developing layer, and the color-developing layer is connected to the sweat-absorbing layer through the air-permeable holes.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows: This medical tape adopts a novel structural design, and the specific content is as follows:

[0018] (1) When it is necessary to remove the medical tape from the patient's skin, just tear the easy-to-tear member first. At this time, the easy-to-tear member no longer blocks the air inlet hole, so that the iron powder in the storage cavity comes into contact with the outside air and generates heat, softening the paste layer and reducing its adhesion to the skin. Then, the medical staff holds the easy-to-tear member and slowly and steadily removes it along the direction of the skin texture, thus avoiding rapid and violent tearing, which may cause pain and skin damage to the patient;

[0019] (2) By setting the tear line, medical staff can tear off a part of the medical tape along the tear line, thereby facilitating tearing off part of the medical tape;

[0020] (3) The antibacterial layer can prevent the growth of bacteria in the medical tape during use, thereby avoiding the occurrence of bacterial allergies. At the same time, the elastic force of the elastic member itself can effectively buffer the pulling force when the medical tape is pulled, thereby preventing the medical tape from being broken;

[0021] (4) The breathable layer and the breathable holes are used together to improve the breathability of the medical tape after it is pasted, thereby avoiding the redness and allergies of the patient's skin caused by poor air circulation and improving comfort. At the same time, the sweat-absorbing layer can absorb sweat from the patient's skin, and the color-developing layer will change color when it comes into contact with sweat, thereby reminding patients and medical staff that the medical tape has lost its stickiness due to excessive sweat and is prone to falling off.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Please refer to Figures 1-6 , the present utility model provides the following technical solutions: a medical tape;

[0031] Example 1: To solve the problem that in the prior art, when medical staff remove the tape body, they need to first pick out a corner of the tape body with their fingernails and then quickly and violently tear it off to separate it from the patient's skin, which easily tears off the hair on the skin together with the tape, causing pain to the patient. At the same time, the method of removing the medical tape is relatively inconvenient. Therefore, the following solution is disclosed. Specifically, refer to Figures 1-4 as shown in the figure, it includes a base layer 1, a paste layer 2 is arranged below the base layer 1, and a surface layer 10 is arranged above the base layer 1;

[0032] It further includes: a storage cavity 13 is opened inside the base layer 1, a tear line 4 is arranged between two base layers 1, an easy-to-tear part 5 is connected at the corner of the upper surface of the base layer 1, an air inlet hole 12 is opened between the easy-to-tear part 5 and the storage cavity 13, iron powder is stored inside the storage cavity 13, and the inside of the storage cavity 13 and the air inlet hole 12 are interconnected. The bottom of the easy-to-tear part 5 is hermetically connected to the top of the air inlet hole 12, and the corner of the outside of the easy-to-tear part 5 is adhesively connected to the base layer 1. Moreover, tear lines 4 are arranged at the connection positions between both sides of the easy-to-tear part 5 and the base layer 1;

[0033] During use, medical staff first tear off a part of the medical tape along the tear line 4 for use, and then the medical tape is pasted on the patient's skin through the paste layer 2 for use. Then, when it is necessary to remove the medical tape from the patient's skin, just tear off the easy-to-tear part 5 first. At this time, the easy-to-tear part 5 no longer blocks the air inlet hole 12, so that the iron powder in the storage cavity 13 comes into contact with the outside air and generates heat, softening the paste layer 2 and reducing its adhesion to the skin. Then, the medical staff holds the easy-to-tear part 5 and slowly and steadily tears it off along the skin texture direction, thus avoiding rapid and violent tearing, which causes pain and skin damage to the patient.

[0034] Example 2: Different from Example 1, in this example, by using the elasticity of the elastic block 11 itself, when the medical tape is pulled, the pulling force can be effectively buffered to avoid the medical tape from being broken. Specifically, refer to Figure 1 and Figure 5 as shown in the figure, an antibacterial layer 3 is thermally bonded between the base layer 1 and the paste layer 2, and elastic blocks 11 are adhesively connected to both the left and right sides inside the base layer 1. The two elastic blocks 11 are symmetrically distributed inside the base layer 1, which can improve the tensile performance of the base layer 1;

[0035] When the medical tape is used by sticking it to the patient's skin, the antibacterial layer 3 can prevent the growth of bacteria inside the medical tape during use, thus avoiding the occurrence of bacterial allergy. At the same time, by utilizing the elasticity of the elastic block 11 itself, when the medical tape is pulled, the pulling force can be effectively buffered to prevent the medical tape from being broken.

[0036] Embodiment 3: Different from Embodiment 2, in this embodiment, when the turmeric powder in the color-developing layer 9 comes into contact with sweat, the color of the color-developing layer 9 will change, so as to remind patients and medical staff that the medical tape loses its adhesiveness due to excessive sweat and is likely to fall off. For specific reference Figures 1-3 and Figure 6 As shown, the upper surface of the base layer 1 is thermally connected to the breathable layer 6, and the upper surface of the breathable layer 6 is thermally connected to the sweat-absorbing layer 7. The sweat-absorbing layer 7 is made of linen fiber material. Ventilation holes 8 are formed inside the surface layer 10, and a plurality of ventilation holes 8 are evenly distributed inside the surface layer 10. The breathable layer 6 is made of polyester fiber material. The upper surface of the surface layer 10 is thermally connected to the color-developing layer 9. Turmeric powder is stored inside the color-developing layer 9, and the color-developing layer 9 is communicated with the sweat-absorbing layer 7 through the ventilation holes 8;

[0037] By using the breathable layer 6 and the ventilation holes 8 in cooperation, the breathability of the medical tape after sticking can be improved, thus avoiding the occurrence of skin flushing and allergy in patients caused by poor air circulation and improving comfort. At the same time, the sweat-absorbing layer 7 can absorb the sweat on the patient's skin and enter the color-developing layer 9 through the ventilation holes 8 to contact the turmeric powder inside, causing the color of the color-developing layer 9 to change, thereby reminding patients and medical staff that the medical tape loses its adhesiveness due to excessive sweat and is likely to fall off.
