Description

Foam anti-pressure sore pad

Technical Field

The utility model relates to the technical field of foam anti-pressure sore pads, in particular to a foam anti-pressure sore pad.

Background Art

Foam anti-pressure sore pads are used to prevent and relieve pressure sores in patients after surgery or who sit or lie for a long time. In recent years, the number of traffic accidents has increased significantly. Secondly, my country has now entered the ranks of an aging society. With age, the skin becomes thinner, subcutaneous fat decreases, and the functions of various organs decline to varying degrees, making it easy to develop various common diseases. The elderly and those injured in accidents sit or lie for a long time during the day, which will hinder blood circulation in the protruding bones, causing tissue malnutrition and necrosis, which can easily lead to pressure sores. During this period, patients who sit or lie for a long time must pay attention to preventing pressure sores. Most patients will choose to use foam anti-pressure sore pads.

At present, there are water cushions and air cushions on the market, and the prices range from tens to hundreds of yuan. Water cushions are effective, but they are very heavy. Air cushions are relatively cheap, but they cannot be used once they are damaged. In addition, some anti-pressure sore pads use acrylic pressure-sensitive adhesive to fit the skin. This type of anti-pressure sore pad has higher peeling strength, is not easy to tear off, and is more likely to cause allergies. Silicone gel foam anti-pressure sore pads have good biocompatibility, are less irritating to the patient's skin, and are gentle when peeled off without causing pain. To this end, we propose a foam anti-pressure sore pad.

The polyurethane film layer A and the polyurethane film layer B are both 15um pink polyurethane films, which are waterproof and antibacterial, and have moisture permeability and air permeability. As a further improvement, the polyurethane film adopts a hydrophilic high moisture permeability polyurethane film. The hydrophilic carboxyl and alcohol functional groups are introduced into the hydrophilic high moisture permeability polyurethane film during synthesis. Compared with the common polyurethane films on the market, the water vapor permeability reaches 3000g/24H*m2 (YY/T 0471.2 standard test), the hardness is Shore A40-60, and it is soft and comfortable when applied to human skin.

Perforated silicone gel mesh layer A and perforated silicone gel mesh layer B are both milky white PE original films with a thickness of 0.1mm;

The thickness of the polyurethane foam layer A and the polyurethane foam layer B is 3-5 mm. The material is soft in texture, has a good decompression and pressure prevention effect, and has good water absorption effect and good air permeability.

Specifically, the pressure-sensitive adhesive layer includes silicone gel A and silicone gel B.

The pressure-sensitive adhesive of this process is soft and skin-friendly. The peeling force is uniform when the patient peels it off after use, and the pain caused by peeling it off is reduced. In addition, the pressure-sensitive adhesive punching process is carried out during the processing, which makes the product more breathable.

Specifically, the perforated silicone gel mesh layer A, the polyurethane foam layer A, the polyurethane film layer A and the pressure-sensitive adhesive layer are distributed on the surface of the isolation layer A in sequence.

By adopting the above technical scheme, the perforated silicone gel mesh layer A, polyurethane foam layer A, polyurethane film layer A and pressure-sensitive adhesive layer distributed in sequence on the surface of the isolation layer A can cooperate with each other, making it convenient for users to use the medical sterilized edged foam anti-pressure sore pad.

Specifically, the perforated silicone gel mesh layer B, the polyurethane foam layer B and the polyurethane film layer B are distributed on the surface of the isolation layer B in sequence.

By adopting the above technical solution, the perforated silicone gel mesh layer B, polyurethane foam layer B and polyurethane film layer B distributed in sequence on the surface of the isolation layer B can cooperate with each other, making it convenient for users to use the medical sterile borderless foam anti-pressure sore pad.

Compared with the prior art, the utility model has the following beneficial effects:

Foam anti-pressure sore pads are divided into bordered and borderless types according to their structures. Users can make reasonable choices according to different parts of the body, which can effectively prevent deviation and falling off during use. At the same time, the adhesive layer of the foam anti-pressure sore pad is a combination of polyurethane film and a two-component mixture of medical silicone gel A and silicone gel B. The pressure-sensitive adhesive formed by the combination of the two silicone gels has good adhesion and peeling strength. It is not easy to fall off or shift when applied to human skin, and it is not easy to pry open or leak at the edge. In addition, the foam anti-pressure sore pad under this process has good air permeability. The lower peeling strength of the silicone gel at the edge will not cause pain to the patient when it is torn off. At the same time, silicone gel has good biocompatibility, and it is not easy to cause allergies and discomfort to the user after being applied to the patient's skin. At the same time, the foam anti-pressure sore pad adopts a combination of perforated silicone gel and polyurethane foam. This process makes the product more breathable, and can effectively absorb liquid into the polyurethane foam through numerous holes, which is highly practical.
