Abstract:

Objective To design and produce an intelligent body pressure measuring mattress and to test its effectiveness in bedridden patients. Methods The body pressure measuring mattress consists of latex mattress，film pressure sensor，measuring machine and display host. From January 2022 to September 2022，110 bedridden patients in a tertiary care hospital were selected. The random number table method was used to randomly divide them into an experimental group with 55 cases and a control group with 55 cases according to the time of admission. The experimental group received the self-designed intelligent body pressure measuring mattress that consists of latex mattress，film pressure sensor，measuring machine and display host，whereas the control group used Shanghai Sanma brand inflatable mattress. The degree of comfort within 7 days，the average number of patients turn over times in 24 hours，and the incidence of pressure injury were compared. Results The average comfort score in the experimental group was（8.92±0.66），which was significantly high（P<0.01） than （6.03±1.76） in the control group，and the mean number of 24 h turns in the experimental group was（7.48±1.41），which was significantly less（P<0.01） than （11.98±0.07） in the control group. The incidence of stress injury in the experimental group was 1.9%，which was significantly lower（P<0.05） compared to 9.1% measured in the control group. Conclusion The intelligent body pressure measuring mattress can conduct real-time posture monitoring of bedridden patients，providing scientific turning basis for nursing staff，while improving the comfort of bedridden patients，and reducing the workload of nursing turning over；therefore，decreasing the incidences of pressure injury.

摘要：

目的 设计、制作智能体压测量床垫，评价其在卧床患者中的应用效果。 方法 体压测量床垫由床垫、薄膜压力传感器、测量从机和显示主机等组成。采用便利抽样法，选取某三级甲等医院2022年1月—9月在院卧床患者110例，采用随机数字表法分为试验组和对照组，每组各55例，试验组使用自行设计的智能体压测量床垫，对照组使用某品牌充气床垫。比较两组7 d内的卧床舒适度、患者24 h平均翻身次数、压力性损伤发生率。 结果 试验组脱落3例，试验组舒适度得分（8.92±0.66）分高于对照组（6.03±1.76）分，试验组24 h翻身次数为（7.48±1.41）次，少于对照组翻身次数（11.98±0.07）次，差异均具有统计学意义（P<0.05）。试验组压力性损伤发生率1.9%低于对照组9.1%，差异具有统计学意义（P<0.05）。 结论 智能体压测量床垫可进行卧床患者实时姿态监测，为护理人员提供科学的翻身依据，在提高卧床患者的舒适度的同时，减少护理翻身工作量，降低压力性损伤的发生率。
