ObjectiveTo explore a strategy for selecting and evaluating the warranty contract of medical equipment.MethodsBased on the operating costs of the two linear accelerators between 2016 and 2019, we obtained the criticality of medical equipment by using the five indicators, including necessity of maintenance, function, risk, importance, and age of medical equipment, selected the warranty strategy by comparing the cost of key components, and adjusted and optimized the warranty strategy based on the economic benefit assessment during the implementation process of warranty contract.ResultsThe criticalities of the two linear accelerators were both 18 points, and it was recommended to purchase warranty service. By comparing the cost of key components, the annual average maintenance cost of the key components of the two accelerators was lower than the annual warranty cost, so we chose the semi-guaranteed contract. Finally, according to the economic benefit accounting and evaluation in the implementation process of the warranty contracts of the two linear accelerators, the linear accelerator 1 remained unchanged, and the linear accelerator 2 was turned from the semi-guaranteed contract into the full insurance contract when we renewed the warranty contract.ConclusionsThe warranty contract selection and evaluation strategy proposed in this paper has certain guiding significance for the choice of strategy of warranty contract. By choosing the appropriate warranty service scope and warranty strategy, and continuous adjusting and optimizing according to the actual performance of the contract, we can effectively guarantee the operational efficiency of medical equipment, and reduce operating costs simultaneously.
ObjectiveTo strengthen the management of medical equipment and improve the use value of medical equipment by PDCA cycle.
MethodsBetween March and June 2014, we introduced PDCA cycle into the management and use of newly-bought equipment.The use of newly-bought arteriosclerosis detector, TCD and ultrasound bone densitometer between March and June 2014 was regarded as the control group (before the implementation of PDCA cycle), and the use of these three kinds of equipment between March and June of 2015(after the implementation of PDCA cycle) was seen as the observation group.By analyzing the status quo through collected information, we drew a fishbone diagram to find out the factors that could influence the use efficiency of medical equipment.Then, corresponding measures were taken for continuous improvement, including adopting revised regulations, training technicians, quantifying work indexes, informatization, changing service mode, and examining and assessing the effect of implementation.Finally, feedback was summarized for the next PDCA cycle.
ResultsAfter the implementation of PDCA cycle, the daily check numbers of hospital medical equipment including arteriosclerosis detector, TCD, and ultrasound bone densitometer all improved significantly (P < 0.05).The daily check numbers of those three kinds of equipment after the implementation of PDCA cycle were respectively 48.52±19.72, 32.14±10.14 and 55.59±25.12, while the numbers before were respectively 32.46±20.69, 15.46±10.05 and 29.83±20.20.Moreover, working days, maximum working hours daily, and total working time were also increased after the implementation of PDCA cycle.
ConclusionThe application of PDCA cycle can effectively improve the use value of medical equipment, and improve the social benefit and economic benefit.

The goal of this paper is to solve the problems of large volume, slow dynamic response and poor intelligent controllability of traditional gait rehabilitation training equipment by using the characteristic that the shear yield strength of magnetorheological fluid changes with the applied magnetic field strength. Based on the extended Bingham model, the main structural parameters of the magnetorheological fluid damper and its output force were simulated and optimized by using scientific computing software, and the three-dimensional modeling of the damper was carried out after the size was determined. On this basis and according to the design and use requirements of the damper, the finite element analysis software was used for force analysis, strength check and topology optimization of the main force components. Finally, a micro magnetorheological fluid damper suitable for wearable rehabilitation training system was designed, which has reference value for the design of lightweight, portable and intelligent rehabilitation training equipment.

Objective To provide theoretical basis for the reasonable selection of personal protective equipment by analyzing the willingness of protection and the contamination of severe acute respiratory syndrome coronavirus 2 of medical staff in the designated hospital for treatment of coronavirus disease 2019. Methods The medical staff of Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine who entered the contaminated area from May 1 to 31, 2022 were collected as the study subjects. A simple random sampling method was adopted to investigate the willingness of protection of different medical staff leaving the cabin. Contamination of severe acute respiratory syndrome coronavirus2 was detected by fluorescence polymerase chain reaction. Results A total of 70 medical staff were included. There were 61 nurses and 38 in intensive care unit. The survey showed that 47 medical staff chose disposable isolation clothes, 44 medical staff chose protective face screen and 69 medical staff chose double-layer shoe cover/boot cover. A total of 640 specimens were collected. Six positive samples for severe acute respiratory syndrome coronavirus2 nucleic acid test were detected, with a positive rate of 0.94%. All the positive samples were sampled from the sole of a protective clothing. Six positive samples were willing to choose double-layer shoe cover/boot cover. Conclusions The medical staff in designated hospital for treatment of coronavirus disease 2019 tend to take high protection during daily medical activities. However, personal protective equipment is less likely to be contaminated by severe acute respiratory syndrome coronavirus2, and it should be selected rationally to avoid excessive protection.
Objective To understand the current situation of the use and cognition of personal protective equipment (PPE) by healthcare workers in the isolation wards (rooms) during the coronavirus disease 2019 epidemic, and provide data support for the country to further optimize the configuration of PPE and carry out more targeted training and supervision. Methods In March 2020, healthcare workers in isolation wards (rooms) in provinces and cities in the country were investigated by filling in a questionnaire about the use of different levels of PPE. Results A total of 6 859 questionnaires were collected from 29 provinces and cities, containing 5 935 valid questionnaires (86.53%). Among them, there were 448 assisting-Hubei medical team members and 5 487 non-assisting-Hubei healthcare workers. The actual use rate (74.22%) and intended use rate (73.14%) of surgical masks in the cleaning areas were the highest. The actual use rate and intended use rate of working caps in potentially contaminated areas and contaminated areas were higher than 90%. There were various combinations of protective articles, and there were significant differences between actual use and intention (P<0.05). Except for the boot covers (single layer) in the cleaning areas, the working caps, isolation clothing and boot covers (double layer) in the potential pollution areas, and the protective face screens, working caps, three-layer shoe covers and single/double/three-layer boot covers in the pollution areas-splashing operations (P>0.05), the actual utilization rates of protective articles of the assisting-Hubei medical team members were generally higher than those of the non-assisting-Hubei healthcare workers (P<0.05). Conclusions The instructions for the use of PPE in different areas and operations should be further refined, and standardized training should be increased. The phenomenon of non-standard use of protective equipment should be reduced, and a safety barrier should be provided to the healthcare workers.
