Description

A stretchable band-aid

technical field

The utility model relates to the field of medical supplies, in particular to a stretchable band-aid.

Background technique

In daily life production, Band-Aid is a commonly used dressing material for wrapping and treating body surface wounds. Conventional Band-Aids are generally composed of medical cotton cloth and a drug-coated layer, and can be used at the position of the body surface wound. It is more convenient to treat wounds and has been widely used. According to statistics - at present, the market capacity of Band-Aid in my country has reached more than 900 million pieces, and the annual market capacity is about 300 million to 400 million yuan, with an annual growth rate of about 10%, which is a relatively fast growth rate. Therefore, Band-Aid has a huge consumer market in our country. However, the band-aids in the domestic market are very thin and clumsy, and have the following defects, such as: hindering the flexibility of the joints; not firm, easy to fall off; poor air permeability; when a collision occurs, it is easy to cause secondary injuries to the wound. At present, there is no beautiful, waterproof, breathable, anti-collision and very flexible band-aid on the market, and the new spiral band-aid has these functions and properties. It is born to protect the wound and is the umbrella of the wound. It also fills a gap in the market.

Utility model content

Aiming at the technical problems in the prior art, the purpose of this utility model is to provide a stretchable band-aid that is adaptable to the use of joints and has strong flexibility.

In order to achieve the above object, the utility model adopts the following technical solutions:

A stretchable band-aid, comprising: a central part and an adhesive part arranged around the central part; the central part is a multi-layer laminated structure and is provided with a telescopic structure; Buffering anti-collision layer, waterproof and breathable layer, adsorption layer, drug inner layer; three-dimensional holes are arranged on the inner layer from the outer layer of the central part; broken broken lines are arranged on the pasting part.

Preferably, the telescopic structure is a spiral telescopic structure or a folding fan structure.

Preferably, the three-dimensional holes are hexagonal truncated holes or cylindrical holes or conical holes or cube-shaped holes. After adopting this structure, the three-dimensional holes can effectively improve the air permeability of the wound.

Preferably, the telescopic structure is provided on the adhesive plaster layer, and the adhesive plaster layer and the sticking part are integrally structured.

Preferably, a decorative pattern layer is drawn on the outer surface of the adhesive plaster layer. After adopting this structure, the Band-Aid is more beautiful.

Preferably, the buffering anti-collision layer is made of adhesive plaster or soft foam elastic material, the waterproof and breathable layer is made of waterproof and breathable material, the adsorption layer is made of medical cotton, and the drug inner layer is ethanol cotton or iodophor cotton. After adopting this structure, the buffering anti-collision layer avoids the secondary injury caused by the impact of the wound, which is beneficial to the wound healing at the first time. The waterproof and breathable layer protects the wound from being soaked in water while ensuring the breathability of the wound.

Preferably, the waterproof and breathable material is thermoplastic polyurethane elastic rubber.

Preferably, a wing is provided on both sides of the sticking portion in the width direction. After adopting this structure, side leakage can be prevented and wound infection can be avoided at the same time.

Preferably, the breaking broken line is arranged along the length direction of the sticking part. After adopting this structure, the flexibility of the band-aid is enhanced and the sense of tightness is reduced; when the band-aid is torn in different directions, it will be broken into different pieces along the breaking line without falling off.

Preferably, reinforcing glue is coated around the outer edge of the sticking part. After adopting this structure, only the reinforcing glue is applied around the outer edge, which not only enhances the sticking force, but also reduces the pain in a large area of the skin when it is torn off.

In general, the utility model has the following advantages:

The band-aid of the utility model has simple structure and beautiful appearance. Due to the arrangement of the telescopic structure and the broken broken line, the band-aid is more flexible in use and reduces the sense of tightness at the same time by utilizing the flexibility of the stretchable structure and the tearability of the broken broken line.

Detailed ways

The utility model will be described in further detail below in conjunction with the accompanying drawings and embodiments.

A stretchable band-aid, as shown in Figures 1-3 and Figure 6, includes: a central part 1, an adhesive part 2 arranged around the central part 1; the central part 1 is a multi-layer laminated structure, and when in use, the central part 1 From the outer layer to the inner layer, there are adhesive plaster layer, buffer and anti-collision layer, waterproof and breathable layer, adsorption layer, drug inner layer; The drug inner layer is pressed together for processing. The adhesive plaster layer is provided with a spiral expansion structure 3, and the outer surface of the adhesive plaster layer is drawn with a pattern decoration layer using food coloring. Make the Band-Aid more aesthetically pleasing. The center part 1 is provided with a hexagonal platform hole 4 on the outer layer to the inner layer, as shown in FIG. 5 , to improve the air permeability of the wound. A breaking line 6 is provided on the sticking portion 2 .

The buffer and anti-collision layer is made of adhesive plaster, the waterproof and breathable layer is made of thermoplastic polyurethane elastic rubber, the adsorption layer is made of medical cotton, and the inner layer of medicine is ethanol cotton sheet. The cushioning anti-collision layer avoids the secondary injury caused by the impact of the wound, which is conducive to the healing of the wound at the first time. The waterproof and breathable layer protects the wound from being soaked in water while ensuring the breathability of the wound.

Both sides of the sticking part 2 in the width direction are respectively provided with a side wing 7 to prevent side leakage and wound infection at the same time. The side wings 7 and the sticking part 2 ensure that the central part is not deformed.

The breaking line 6 is arranged along the length direction of the sticking part 3 . Enhance the flexibility of the Band-Aid and reduce the sense of tightness; when the Band-Aid is torn in different directions, it will be broken into different pieces along the breaking line 6 without falling off. A reinforcing glue 5 is coated around the outer edge of the sticking portion 2 . The reinforcement glue 5 is only applied around the outer edge, so as to enhance the sticking force and reduce the pain in large areas of the skin when it is torn off.
