ABSTRACT
Based on the Kraljic model,this paper established the scoring standard system for medical equipment procurement,and determined the weight coefficients of each evaluation factor by the analytic hierarchy process (AHP),then the procurement classification model of medical equipment was successfully established.It is proved that this model can classify medical equipment effectively,which enables the purchasing personnel to adopt corresponding purchasing strategies according to different classification.This model can be extended to all medical equipment procurement,realizing the delicacy and individualized procurement management of the equipment,which has strong operability and guiding significance.

In this paper, the classification and location of neuroblastoma in NMR images are realized by using Deep Neural Network(CNN) algorithm as the core technology. The module is integrated to realize the development of computer-aided diagnostic software. It is used to make up for the gap in the field of intelligent identification and accurate positioning of neuroblastoma in the current nuclear magnetic resonance detection technology, effectively reduce the work intensity of doctors reading films, and further promote the clinical application and technical development of nuclear magnetic resonance detection technology in the diagnosis of neuroblastoma.

This paper proposes a clinical alarm management system based on the theory of the closed loop control. The alarm management mechanism can be divided into the expected standard, improving execution rule, rule execution, medical devices with alarm functions, results analysis strategy and the output link. And, we make relevant application and discussion. Results showed that the mechanism can be operable and effective.

This study is aimed to design the testing system of multiple parameters of the incubators, and to make their quality control plans. Also it is required to establish a model of data collection and processing based on MCU, and to program the host computer software in order to analyze data. The result shows that the testing system is accurate and stable; also it is convenient to collect the data. This testing system is a good complement of the quality control of incubators. It has a high practical value in improving medical safety and reducing the occurrence of adverse events.

With the continuous improvement and wide application of hospital information, more and more medical equipment is integrated into the hospital information systems, which brings new work contents and challenges for the traditional clinical engineers. This paper reviews and evaluates the current situation of networked medical equipment in the hospital. By applying the ISO 80001 and the MDS(Manufacturer Disclosore Statement for Medical Device Security), the paper puts forward the measures and suggestions for the security management of networked medical equipment.

The content related to the quality during life-cycle in operation of medical device includes daily use, repair volume, preventive maintenance, quality control and adverse event monitoring. In view of this, the article aims at discussion on the quality evaluation method of medical devices during their life cycle in operation based on the Analytic Hierarchy Process (AHP). The presented method is proved to be effective by evaluating patient monitors as example. The method presented in can promote and guide the device quality control work, and it can provide valuable inputs to decisions about purchase of new device.

As the dressings currently used in clinic settings unflat shape in general, they can't be fitted completely on occiput, heel, elbow, knee and other body parts unflat. This paper developed one kind of foam dressing of special shape based on local anatomy. The foam dressing is waterproof and air permeable, it can cover the wound closely enough to prevent bacteria from invasion and infection. With a saturated absorption ratio of 1: 8 or higher, it can keep the wound clean and moisture by absorbing large amounts of wound inflammatory secretions and is almost completely permeable to oxygen and carbon dioxide. Assuring safety and effect meanwhile, it has better outcomes than common dressings in the same application settings.

This paper analyzed current problems and challenges facing hospitals in alarm management both abroad and at home. Based on a survey conducted on alarm management in hospitals, plus an analysis on different kinds of data interfaces and data exchange protocols of the medical equipment used in ICUs, a solution of alarm management is put forwarded which is based on alarm information integration and processing. It aims at improving medical equipment alarm management and reducing relevant adverse events.

Human factors engineering is a promising interdisciplinary subject in applied sciences.This study presented the development and research purposes of human factors engineering.Based on case studies,the authors probed into the importance of the engineering in the design,management and procurement of medical equipments,for the purpose of optimizing medical equipment design,manufacturing and procurement.
ABSTRACT
Investigated and analyzed the graphical symbols commonly used in medical equipment, their benefits and drawbacks. From the perspective of human factors engineering, some root causes of poor pictogram as well as their relations with medical equipment adverse events were addressed. Furthermore, how to deal with the problems with current pictogram aiming at reducing use error was also discussed.
