Description

Technical Field

[0001] The utility model relates to the field of cushions, in particular to a cushion structure for nursing heart failure patients. Background Art

[0002] Heart failure is a complex clinical syndrome caused by various heart diseases progressing to a severe stage. Its main characteristics are left ventricular and right ventricular dysfunction and changes in neurohumoral regulation, often accompanied by dyspnea, fluid retention, decreased exercise tolerance and significantly shortened survival time.

[0003] When a heart failure patient lies in bed, a pillow is usually placed behind his back to facilitate lying with his upper body tilted. Existing pillows are usually composed of an inner soft core and an outer wrapping cover, so that the thickness of the pillow is constant. If the patient needs to change the tilt height when lying down, it is necessary to add bedding to the bottom of the pillow to increase the thickness of the pillow. However, directly adding bedding to the bottom of the pillow will make the pillow tilted and unstable, and it is not convenient to directly adjust the tilt angle of the pillow so that the pillow is at a certain tilt angle to support the patient's back.
