Objective Our objective was to design a new type of bedpan (inflatable, bed urinal) and compare its effect with common bedpan. Methods We divided 144 patients with bone fracture and lying in bed into the test group and the control group with 72 cases in each group from May 2006 to February 2007. Inflatable bed urinals were used in the test group and common bedpans were used in the control group. The pain alleviation, comfort degree, staining of bed sheet and skin injury were observed and evaluated in each group. Results Application of inflatable bed urinal was superior to common bedpan in the following aspects: alleviation of pain, comfort degree, staining of bed sheets and skin injury. Conclusions Adoption of inflatable bed urinal could alleviate pain, prevent the incidence of complication and reduce the workload of nurses.

Objective:To explore the application effect of the "4M1E" comprehensive management mode (man, machine, material, method, environment) in ultrasonic examination, and to provide reference for the health management center of hospitals to formulate reform measures to improve the quality and efficiency of ultrasonic examination.Methods:By adoping a non-randomized controlled research, a total of 400 clients who underwent physical examination in the Health Management Center of Zhujiang Hospital, Southern Medical University were selected as subjects by convenience sampling method. Among them, 200 clients who underwent physical examination from August to October 2021 were selected as the control group to implement routine physical examination mode, another 200 clients who underwent physical examination from August to October 2022 were selected as the experimental group to implement the "4M1E" comprehensive management mode. The ultrasonic examination time, passing rate, bladder filling, pre-examination knowledge score and satisfaction of the two groups were compared.Results:The ultrasonic examination time of experimental group was (9.54 ± 3.25) min, lower than (12.33 ± 5.07) min of control group, and the difference was statistically significant ( t=6.53, P<0.05). The passing rates of ultrasonic examination at 1 time, 2 times and 3 times in the experimental group were 86.0% (172/200), 12.0% (24/200) and 2.0% (4/200), respectively, which were better than 73.5% (147/200), 20.5% (41/200) and 6.0% (12/200) in the control group with statistical significance ( χ2=10.05, P<0.05); the proportions of overfilling, proper filling and poor filling in the experimental group were 1.0% (2/200), 86.0% (172/200) and 13.0% (26/200), respectively, which were better than 2.0% (4/200), 70.0% (140/200) and 28.0% (56/200) in the control group, the differences of two groups were statistically significant ( χ2=14.93, P<0.05). Pre-examination knowledge score of experimental group (8.16 ± 1.43) was higher than that of control group (6.19 ± 1.94) points, and the difference was statistically significant ( t=-11.48, P<0.05). The overall satisfaction score of the experimental group (20.55 ± 2.46) was higher than that of the control group (18.45 ± 2.86). The differences was statistically significant ( t=-7.87, P<0.05). Conclusions:The "4M1E" comprehensive management mode can make physical examination clients fully prepare for the examination, reduce the time of ultrasonic examination, complete the examination efficiently, and comprehensively improve the sense of experience and satisfaction.
