Description

Ultrathin adhesive bandage

Technical Field

The utility model belongs to the technical field of medical dressing, specifically relate to an ultra-thin band-aid.

Background

The adhesive bandage is a necessary disposable surgical medicine commonly used in families and hospitals, can be used for slight scratch and abrasion without sewing a needle wound, and has the functions of protecting the wound, preventing bacteria from invading and the like. The existing wound covering comprises a backing, a water absorption pad, left release paper and right release paper, wherein an adhesive is coated on the backing and is connected with the water absorption pad through the adhesive, and the left side of the left release paper and the right side of the right release paper are respectively adhered to two ends of the backing. During the use, tear left release type paper or right release type paper, then will tear the one end of the adhesive bandage of release type paper and paste in one side of injured part, the water absorption pad aims at injured part, tears another release type paper simultaneously, smooths and fixes. However, after the existing adhesive bandage is attached to a wound, the adhesive layer covers the skin and is airtight, so that the skin is prone to whitening after being used for a period of time, and the longer the using time is, the greater the damage to the skin is. Meanwhile, the absorbent pad of the existing adhesive bandage is made of needle-punched non-woven fabrics, the thickness of the absorbent pad is 1 +/-0.1 mm, the thickness of the absorbent pad is thick, and when a wound is at a knuckle part, the adhesive bandage can affect the movement of the knuckle after being attached to the wound, so that discomfort is caused.

Disclosure of Invention

The utility model discloses solve the technical problem that above-mentioned prior art exists, provide an ultra-thin band-aid.

The above technical problem of the present invention can be solved by the following technical solutions: the utility model provides an ultra-thin adhesive bandage, includes backing, adhesive layer, water absorption pad and leaves type paper, the adhesive layer pastes the lower surface that covers at the backing, the water absorption pad is located the middle part of backing lower surface, the upper surface that absorbs water the pad is equipped with the glue of the punctiform that is the matrix distribution to link to each other with the backing through glue, the water absorption pad comprises water-gel nature spunlace non-woven fabrics, it has two to leave type paper, and the overlap covers on water absorption pad and the adhesive layer.

Preferably, the thickness of the water-gel spunlace nonwoven fabric is 0.2 +/-0.1 mm.

The utility model discloses beneficial effect who has: the utility model discloses in, the pad that absorbs water passes through glue and links to each other with the backing, and glue adopts the design that is matrix punctiform and distributes, utilizes lower coating volume can obtain sufficient bonding strength, has reduced the use amount of glue, has reduced manufacturing cost, simultaneously because the pad that absorbs water and the incomplete laminating of backing form the space between the two, make things convenient for the circulation of air, improved the gas permeability greatly. The water absorption pad is made of water-gel spunlace non-woven fabrics, so that the thickness of the water absorption pad is greatly reduced, the movement of the knuckle is not influenced when a wound is at the knuckle, and discomfort is not caused; on the other hand, the water-gel spunlace non-woven fabric has good water absorption, can generate gel when meeting water, has good gelling effect, can be directly gelled by pure water, can add liquid medicines for hemostasis, antibiosis and the like in advance by utilizing the characteristic, and then carries out dry-state treatment on the water-gel spunlace non-woven fabric.

Detailed Description

The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.

Example (b): the utility model provides an ultra-thin band-aid, as shown in fig. 2-5, includes backing 1, adhesive layer 2, water absorption pad 3 and leaves type paper 4, adhesive layer 2 pastes and covers the lower surface at backing 1, water absorption pad 3 is located the middle part of backing 1 lower surface, the upper surface of water absorption pad 3 is equipped with the glue 5 that is the punctiform of matrix distribution to link to each other with backing 1 through glue 5, water absorption pad 3 comprises water gel nature spunlace non-woven fabrics, and the thickness of water gel nature spunlace non-woven fabrics is 0.2 +/-0.1 mm, leave type paper 4 have two, overlap and cover on water absorption pad 3 and adhesive layer 2.

The back lining 1 is formed by alternately weaving warps and wefts, the warps are composite yarns 6, the composite yarns 6 comprise core wires and cotton fibers 7 spirally wound on the peripheries of the core wires, the core wires are composed of two bamboo fibers 8 spirally wound in opposite directions, the wefts comprise polyester yarns 9 and spandex yarns 10, the polyester yarns 9 are distributed at equal intervals, and the number ratio of the polyester yarns 9 to the spandex yarns 10 is 1: 1.

The water absorption pad is made of water-gel spunlace non-woven fabrics, so that the thickness of the water absorption pad is greatly reduced, the movement of the knuckle is not influenced when a wound is at the knuckle, and discomfort is not caused; on the other hand, the water-gel spunlace non-woven fabric has good water absorption, gels can be generated when meeting water, the gelling effect is good, pure water can be directly used for gelling the water-gel spunlace non-woven fabric, by utilizing the characteristic, liquid medicines for hemostasis, antibiosis and the like can be added into the water-gel spunlace non-woven fabric in advance, then the water-gel spunlace non-woven fabric is subjected to dry-state treatment, active ingredients of the liquid medicines are reserved in the treatment process, and when the water-gel spunlace non-woven fabric is used, the water-gel spunlace non-woven fabric is moistened and uniform by adding appropriate amount of water. The water absorption pad adopts water gel water thorn non-woven fabrics and can add the liquid medicine in advance, need not to wait to add when using, and it is very convenient to use, and can avoid the rotten and the breeding of bacterium of liquid medicine, prolongs the shelf life, effectively remains the active ingredient of liquid medicine.

The water absorption pad is connected with the back lining through glue, the glue adopts the design of matrix point distribution, the enough bonding strength can be obtained by utilizing the lower coating amount, the use amount of the glue is reduced, the production cost is reduced, and meanwhile, because the water absorption pad and the back lining are not completely laminated, a gap is formed between the water absorption pad and the back lining, the air ventilation is facilitated, and the air permeability is greatly improved.

By improving the weaving structure of the backing, the bamboo fiber is added, and the good air permeability of the bamboo fiber is utilized, so that the ventilation is further facilitated, and the skin is prevented from being whitened due to the fact that the skin is not breathable after being coated; utilize the antibiotic bacteriostatic function of bamboo fibre, can filter the air that gets into the pad that absorbs water, absorb harmful gas, isolated peculiar smell gas prevent that bacterial growing. The cotton fibers with high strength, good texture and good comfort degree are spirally wound on the periphery of the bamboo fibers, so that the defects that the bamboo fibers are easy to break and age are effectively overcome. The spandex silk is soft, the air permeability and the elasticity are good, the polyester silk has the characteristics of good elasticity and good antifouling performance, the polyester can prevent stains from permeating, and the back lining has good antifouling effect and stretching effect by combining the spandex silk and the polyester silk.

Finally, it should be noted that the above embodiments are merely representative examples of the present invention. Obviously, the present invention is not limited to the above-described embodiments, and many modifications are possible. Any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention should be considered as belonging to the protection scope of the present invention.
