Description

A new waterproof PE tape

Technical Field

The utility model relates to the technical field of medical tapes, in particular to a novel waterproof PE tape.

Background Art

Medical tape is used when bandaging wounds or giving intravenous drips. There are three common types of medical tapes: cotton tape, non-woven tape, and PE tape. Cotton tape has high viscosity and strength, but is not easy to tear. In actual use, it needs to be used with scissors, which is more troublesome to use; non-woven tape, that is, tape with non-woven fabric as the base material, has moderate viscosity, but low strength and poor fixation. It is generally used to fix injection needles; compared with the first two types, PE tape has moderate strength, good fixation, is easy to tear, has moderate air permeability, and is more suitable.

In actual use, in order to enhance the air permeability of PE tape, holes are punched on the tape substrate, which will affect the tape's waterproofness. PE tape will lose its stickiness and fixation effect when it comes into contact with water. At the same time, the wound will become inflamed when it comes into contact with water, affecting healing. In addition, PE material is hard and will cause friction and dermatitis when it comes into contact with the skin for a long time.

In view of this, we propose a new type of waterproof PE tape.

Please refer to Figures 1-5, the utility model describes the above technical solution in detail through the following embodiments:

A new waterproof PE tape, comprising:

The substrate layer 3 is used to provide support and shaping for the adhesive tape. The substrate layer 3 includes a PE film 31, and the PE film 31 is provided with air holes 32.

The PE film 31 is made of polyethylene and can provide support as a tape substrate. The air holes 32 can increase the air permeability of the substrate layer 3 and facilitate tearing when the tape is torn.

Also includes:

The waterproof and breathable layer 1 is located above the substrate layer 3 . The width of the waterproof and breathable layer 1 is greater than the PE film 31 . The waterproof and breathable layer 1 is made of PTFE.

The waterproof and breathable layer 1 and the substrate layer 3 are bonded with an adhesive. The waterproof and breathable layer 1 is used to isolate external water vapor. The PTFE material has a special fibrous microporous structure. In the state of water vapor, the water particles are very small. According to the principle of capillary motion, they can smoothly penetrate the capillary to the other side, thereby causing the phenomenon of vapor permeability. When the water vapor condenses into water droplets, the particles become larger. Due to the surface tension of the water droplets, the water molecules cannot smoothly break away from the water droplets and penetrate to the other side, which prevents the penetration of water.

The anti-allergic rubber ring 2 is located on the bottom surface of the waterproof breathable layer 1 and on the base material layer 3. The anti-allergic rubber ring 2 is sticky. The anti-allergic rubber ring 2 is a medical pressure-sensitive adhesive. The thickness of the anti-allergic rubber ring 2 is the sum of the thickness of the base material layer 3 and the adhesive layer 4.

The anti-allergic rubber ring 2 can bond the edge of the waterproof breathable layer 1 to the skin, preventing the edge of the base layer 3 and the waterproof breathable layer 1 from rubbing against the skin surface to cause dermatitis, thereby improving the comfort of the tape. The medical pressure-sensitive adhesive material is harmless to the skin.

The adhesive layer 4 is located directly below the base material layer 3 and includes a strong adhesive ring 41. The strong adhesive ring 41 is sticky and has a certain water resistance and is used to adhere the base material layer 3 and the skin. The strong adhesive ring 41 is made of solid butyl rubber.

The solid butyl rubber has a certain waterproof property, and the strong adhesive ring 41 is an interconnected ring structure, which ensures that when the tape is disconnected at any point, the remaining part still has waterproof ability.

A skin-friendly adhesive layer 43 is provided inside the strong adhesive ring 41 and below the PE film 31 . The skin-friendly adhesive layer 43 is made of medical pressure-sensitive adhesive.

The skin-friendly adhesive layer 43 can adhere the PE film 31 to the skin to prevent the tape from being separated from the skin. Meanwhile, the skin-friendly adhesive layer 43 is made of medical pressure-sensitive adhesive material, which can improve the fixing strength while avoiding damage to the skin.

A prompting ring 42 is provided between the skin-friendly adhesive layer 43 and the strong adhesive ring 41 and below the PE film 31 , and the prompting ring 42 is filled with a litmus indicator.

The litmus indicator changes color when acidic or alkaline substances are needed. The pH value of water encountered in daily life is: the pH value of tap water is 6.5-8.5; the pH value of river water is 6-8; the pH value of rainwater is 6.7. Therefore, no matter what kind of water intrudes into the tape, the prompt ring 42 will change color. The prompt ring 42 adopts a ring structure. When the prompt ring 42 changes color completely, the tape needs to be replaced.

In addition, the pH value of sweat is 4.2-7.5, so skin sweating will also cause the prompt circle 42 to change color. When the prompt circle 42 changes color completely, it means that there is too much moisture near the wound and the tape should be replaced.

The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
