The classification and risk analysis of clinical claims for mechanical ventilator / 生物医学工程学杂志

The risk analysis of clinical claims of mechanical ventilator can provide the useful information to the application of the availability and safety of mechanical ventilators. This paper classifies the clinical claims of two types of mechanical ventilations, and tries to find the distribution characteristics of the failure rate of the clinical claims by using the hazard analysis method. All of the distribution characteristics are related to the factors as ventilator design, environment human factors, etc. The method of risk analysis, combining with the classification of clinical claims, is useful for the clinical application and engineering services of mechanical ventilation.

Development of wireless monitoring system for infant bed-wetting / 医疗卫生装备

For the purpose of monitoring real-time information of infant bed-wetting,this paper presents a medical digital wireless monitoring system with low-cost and high-performance. Its hardware is based on micro-controller,MSP430 ultra low-power and RF IC,nRF905 single wireless chip. With this wireless system,real-time information of infant bed-wetting can be monitored,and thus the nurses' work load can be reduced.

Design and application of digital manometer for air-pocket in manual air-way / 医疗卫生装备

This paper discusses the design of a special digital manometer for air-pocket in manual air-way. Integrated silicon pressure sensor MPX5010 with high precision and sensitivity is adopted in the device. It can not only measure and display air pressure of air-pocket,but also give the alarm for excessive pressure,thus providing a timely and convenient way for clinician to control air-pocket pressure,which ensures the safety and precision for clinic.

Wearable COPD pulmonary rehabilitation device and methods / 医疗卫生装备

Objective To design a wearable rehabilitation device suitable for home and society COPD treatment aiming at the deficiency in the COPD pulmonary rehabilitation in China. Methods Physical activity therapy and pulmonary physical therapy methods which play very important role in the COPD pulmonary rehabilitation were studied. Physiological parameters of the COPD patient were acquired non-intrusively with wearable technique. Biofeedback technology was used in the respiratory rehabilitation therapy. Target heart rate and SPO2 were used as parameters for the activity intensity assessment. Results Wearable COPD pulmonary rehabilitation device based on breathing biofeedback was fabricated. Conclusion This device is a favorable rehabilitation tool for COPD patients to do self-training at home or community.
