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.
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.
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.
Continuous renal replacement therapy (CRRT) originated from intermittent hemodialysis. Over the past 40 years, its application scope has gradually expanded from the initial treatment of kidney diseases alone to the support of multi-organ functions. As a safe, adequate, and flexible therapeutic modality, CRRT has become one of the main means of treating critically ill patients. Continuous innovation in technology, biomaterials and other technologies provides important driving force for the sustainable development of CRRT. This paper reviews the technological innovation and development of CRRT devices. With continuous technological updates and iteration, CRRT can better adapt to clinical needs. Biofeedback, portability, and intelligence are several directions of the development of CRRT, which can provide more accurate and personalized treatment for critically ill patients in different scenarios.

Objective To survey the present situation of medical equipment configuration of township hospitals in Shuangliu County, to provide baseline data for the next step of discussing the well-off township hospital medical equipment configuration standards. Methods According to the national guidance on device configuration in township hospitals, the questionnaire was made to survey 24 county township medical units (i.e. 3 central township hospitals, 3 community health centers, and 18 general township hospitals). The descriptive and stratified analysis was performed for the survey results. Results The condition of medical equipment configuration in the 3 central hospitals was better than that in the 3 community health centers which was better than that in the 18 general hospitals. The emergency equipment configuration such as defibrillator units, breathing airbags, and tracheotomy package was poor. Annual inspection rate of medical metering equipment was lower than expectation. In 2010, a total of 127 medical measuring equipments from 98.5% of the township hospitals applied annual inspection, among which, only the total annual rate of black and white B ultrasonic and X-ray machine reached above 60%; the rate of blood cells analyzer, ECG monitoring instrument, and biochemical analyzer were between 50% to 60%; and the rate of urine analyzer was the lowest at 4.5%. Conclusion It is the right time to strengthen the first aid equipment configuration in township hospitals and to enhance the annual inspection rate of the medical measuring equipment, so that the safety use and accuracy detecting can be guaranteed.

This scheme could provide reference for preventing such disease for medical staffs.
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.
