Description

Technical Field

[0001] The utility model relates to an anti-pressure sore pad, in particular to a foldable and detachable breathable anti-pressure sore pad. Background Art

[0002] Bedsores, also known as pressure sores, are common complications among people who are bedridden for a long time. The main cause of their formation is that the local skin, nerves, and blood vessels of the body are compressed for a long time, resulting in skin damage and necrosis, and the local sanitary environment leads to wound infection. The simplest way to prevent bedsores in bedridden patients is to turn them over, generally once every 2 hours, and once every half an hour if necessary. At the same time, other conditions that may cause bedsores should be dealt with in a timely manner. Another key point in the prevention and treatment of bedsores is the breathability of the mattress. A mattress with good breathability can slow down the formation of bedsores.

[0003] There are several types of existing anti-bedsore mattresses: pneumatic anti-bedsore mattresses, concave-convex sponge pads, silicone pads, inflatable pads, etc. These mattresses all have their disadvantages. For example, pneumatic anti-bedsore mattresses are always in a pneumatic state, making a lot of noise, seriously affecting the patient's rest, and greatly reducing comfort. In addition, the mattress is always powered on, and the motor is easy to burn out; the concave-convex sponge pads or silicone pads have poor air permeability and lack of support; ordinary inflatable pads have poor air permeability and durability, and the fabric is not skin-friendly, especially some plastic inflatable pads such as PP and PVC, which are not breathable, skin-friendly, and non-slip. Existing anti-bedsore mattresses also have some common disadvantages, such as they cannot be folded, which is not convenient for moving and carrying, and they cannot be partially folded to perform back massage on patients; they are partially damaged but cannot be partially replaced.
