技术领域technical field
本发明涉及一种危重、意识不清或自身活动障碍病人（偏瘫、截瘫、长期卧床等病人）的治疗床，尤其涉及智能防压疮的气垫床垫。The invention relates to a treatment bed for critically ill, unconscious or self-impaired patients (patients such as hemiplegia, paraplegia, and long-term bedridden patients), in particular to an intelligent anti-pressure sore air mattress.
背景技术Background technique
很多人由于特殊病情或活动障碍等原因，需长时间卧床。医院和家庭为防止压疮的发生，需定时为其翻身。这对医院而言，需要投入大量的护理人力；对家庭而言，需要人专门护理且不能远离左右。可以说翻身成本大，若翻身不及时会明显增加压疮发生可能，而夜间翻身则会打扰患者休息。因此，临床上迫切需要一种可通过电脑控制，自动翻身的气垫床。Many people need to stay in bed for a long time due to reasons such as special illness or activity disorder. In order to prevent the occurrence of pressure sores, hospitals and families need to turn them over regularly. For hospitals, this requires a large amount of nursing manpower; for families, it requires specialized care and cannot be far away. It can be said that the cost of turning over is high. If turning over is not timely, the possibility of pressure sores will be significantly increased, and turning over at night will disturb the patient's rest. Therefore, there is an urgent need for a kind of air mattress that can be automatically turned over by computer control clinically.
