Description

Technical Field

[0001] The present invention belongs to the field of medical auxiliary equipment, and in particular relates to an anti-pressure sore air cushion and an anti-pressure sore device. Background Art

[0002] Patients who are bedridden for a long time (such as vegetative patients or critically ill patients under anesthesia) cannot turn over on their own. Long-term bed rest can cause pressure sores, blisters, and skin ulcers on the patient's skin, especially in the sacrum and scapula, which are more prone to lesions. Pressure sores on patients can cause great harm to patients. Pressure sores that are not cured for a long time are also prone to complications such as osteomyelitis, sepsis, and hypoproteinemia. These complications not only make treatment more difficult, but can also lead to death; if the pressure sores continue to be compressed, the progression of the lesions can cause necrosis and loss of the entire layer of skin. The ulcers often lead to bacterial infections. About half of patients with pressure sores are accompanied by infections. Severe infections can spread directly to deep tissues or nearby joints, leading to osteomyelitis and arthritis. Pressure sores can also induce and aggravate muscle spasms. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide an anti-pressure sore air cushion and an anti-pressure sore device, which can reduce the risk of pressure sores for patients by continuously changing the second air bag to act on different positions of the patient, allowing the patient to turn over and lift up, and allowing air to circulate between the second air bags.

[0004] The purpose of this disclosure can be achieved through the following technical solutions:

[0005] An anti-pressure sore air cushion, comprising:

[0006] A frame, the frame comprising a bottom plate and a surrounding plate fixedly connected to the side of the bottom plate, a partition plate fixedly connected to the middle of the bottom plate, the partition plate divides the frame into two cavities, and each of the cavities is fixedly connected to a plurality of baffles distributed at equal intervals along the length direction of the cavity;

[0007] An air cushion layer, wherein two air cushion layers are embedded in each of the cavities, wherein the air cushion layer comprises a first airbag and a plurality of second airbags fixedly connected to the same side of the first airbag and distributed at equal intervals, wherein the first airbag is embedded in the cavity between the end of the baffle and the enclosure, and the second airbag is embedded in the cavity between adjacent baffles.

[0008] The above technical solution, its principle and technical effect:

[0009] The four air cushion layers are originally filled with a certain amount of gas, so that the height of the four air cushion layers is level with the height of the frame, which is convenient for patients to lie on it. When an air cushion layer in one of the cavities is inflated, the second air bag expands to realize the patient's sideways function. Since there is a gap between the second air bags, air flow is convenient, which reduces the patient's pressure sores. When the air cushion layers in the two cavities are alternately inflated and deflated, the patient can turn over repeatedly to reduce the risk of pressure sores. At the same time, the two air cushion layers in the same cavity work in turns to further reduce the risk of pressure sores.

[0010] In a preferred example, the utility model can be further configured as follows: four first holes and four second holes are opened on the enclosures at both ends of the frame, and an air intake pipe is passed through the four first holes, and the air outlet end of the air intake pipe is fixedly connected to one end of the first airbag and communicated with the interior of the first airbag; an exhaust pipe is passed through the four second holes, and the air intake end of the exhaust pipe is fixedly connected to the other end of the first airbag and communicated with the interior of the first airbag.

[0011] In a preferred example, the utility model can be further configured as follows: the air inlet end of the air inlet pipe is fixedly connected to an air pump, and the air inlet end of the air inlet pipe is connected to the air outlet end of the air pump.

[0012] In a preferred example, the utility model can be further configured as follows: an exhaust valve is fixedly connected to the exhaust pipe.

[0013] In a preferred example, the utility model can be further configured as follows: the second air bags on the two air cushion layers in the same cavity are distributed alternately.

[0014] In a preferred example, the present invention can be further configured as follows: a second airbag is provided between two adjacent baffles.

[0015] In a preferred example, the utility model can be further configured as follows: both ends of the partition are fixedly connected to the enclosure.

[0016] A device for preventing pressure sores comprises an air cushion for preventing pressure sores.

[0017] The nouns, conjunctions or adjectives involved in the above technical solution are explained as follows:

[0018] Fixed connection refers to a connection in which parts or components are fixed without any relative movement. There are two types of connection: detachable and non-detachable.

[0019] (1) A removable connection is a connection that uses screws, splines, wedge pins, etc. to hold parts together. This type of connection can be disassembled for maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened.

[0020] (2) Non-detachable connections mainly refer to welding, riveting and tenoning. Since they need to be disassembled by forging, sawing or oxygen cutting for maintenance or replacement, spare parts generally cannot be reused. At the same time, when making connections, attention should be paid to process quality, technical inspection and remedial measures (such as calibration, polishing, etc.).

[0021] A threaded connection refers to a detachable connection in which the connected parts are connected together using threaded parts (or the threaded parts of the connected parts).

[0022] A sliding connection is when two objects are in contact but not fixed and can slide relative to each other.

[0023] A rotational connection is a connection between parts that allows the parts to rotate relative to each other.

[0024] Beneficial effects of the present disclosure:

[0025] By continuously changing the second airbag's action on different positions of the patient, the patient can be turned over and lifted up, and air can circulate between the second airbags, thereby reducing the patient's risk of pressure sores. BRIEF DESCRIPTION OF THE DRAWINGS
