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.
