An airbag cushion assembly includes an airbag cushion and an inflation-deflation apparatus that communicates with the airbag cushion. The airbag cushion includes a plurality of sub-airbags, and an airbag gap is formed between adjacent sub-airbags. The inflation-deflation apparatus is provided with an exhaust port, the exhaust port is provided in the airbag gap, and the inflation-deflation apparatus is configured to inflate and deflate the airbag cushion. For the airbag cushion assembly, the exhaust port is provided in the airbag gap, air exhausted by the airbag cushion takes away damp air accumulated between a patient and the airbag cushion, to reduce humidity of the contact area between the patient and the airbag cushion, thereby achieving a pressure sore prevention effect.

Airbag cushion assembly, intelligent pressure sore prevention cushion, and monitoring system

There is provided a deep brain stimulation system having k focuses, which comprises: a first electrode and a second electrode, used for connecting one side of a brain scalp; a third electrode and a fourth electrode, used for connecting the other side of the brain scalp; and a first signal generation unit, a second signal generation unit, . . . , a (2k&#x2212;1)signal generation unit and a 2ksignal generation unit, wherein the k is a positive integer greater than or equal to 2; and each of the signal generation units is used for providing the following currents for the first electrode to the fourth electrode: a first current and a second current, which are interfered at a deep portion of a brain to form a first focus; and a (2k&#x2212;1)current and a 2kcurrent, which are interfered at the deep portion of the brain to form a kfocus.

Noninvasive deep brain stimulation system having k focuses

The present invention relates to a cushion for preventing pressure sore. The cushion for preventing pressure sore includes an air cell layer, an air passage layer, a base layer, and a plurality of air ducts. The air cell layer has a plurality of air cells; the air cell layer is divided into at least four air cell zones. Air cells in each air cell zone are in communication with each other, but air cells in any two adjacent air cell zones are not in communication with each other; the air passage layer is under the air cell layer and has a plurality of air passages therein. Each air passage is in connection and communication with at least one of the air cell zones; the air passage layer and the air cell layer are disposed on the base layer; an end of each air duct is in communication with a corresponding air passage, and the other end extends out of the cushion and is provided with a joint; and each air duct has a respective valve. The cushion for preventing pressure sore according to the present invention can intermittently exert pressure over human buttocks, thereby effectively preventing pressure sores.
