Description

Pressure sore prevention pillow for patient

Technical Field

Background

Long-term lying patients, such as long-term coma patients, need to adjust their sleeping positions at intervals, i.e. lying and lying on the side alternately, so as to avoid pressure sores caused by long-term pressure on a certain part of the body. The head of a patient is put on the pillow, and the pillow is soft but can cause pressure sores when the head is pressed for a long time after the patient lies for a long time. The long-term compression of the back of the brain should be avoided when lying on the back, and the long-term compression of the auricle should be avoided when lying on the side.

ZL201821988193.6 discloses a pressure sore prevention pillow, which comprises a pillow body, wherein at least one groove corresponding to an ear is arranged on the pillow body, and when a patient lies on side, the ear is arranged in the groove to prevent the auricle pressure sore. But the pressure sore prevention pillow has no function of preventing pressure sore at the back of the brain.

ZL202020926100.8 discloses a pillow for preventing head pressure sore after craniocerebral operation, which comprises a pillow body, wherein the middle part of the pillow body is provided with a hollowed-out back-head spoon empty groove matched with the back-head spoon. Although the pillow is provided with the hollow groove of the hindbrain scoop, the pressure sore of the hindbrain scoop can be avoided, but the pressure sore can also be caused when the peripheral position of the hindbrain scoop is contacted and pressed with the pillow for a long time.
