ABSTRACT
Objective:Discuss how the management of implantable medical consumables can be standard during the links of production, transportation, internal logistics of the hospital and the sector of using. Methods: In accordance with the relevant national laws and regulations, and long-term management practice and experience, and aiming at the specialty and high risk characteristics of implanting medical consumables, we apply information technique to regulate the standard operation of the whole medical supplies links (raw materials, processing of products, marketing, warehousing transportation, and the usage of the patients), therefore the roots can be traced back. The implanted medical supplies traceability standardized management needs to be explored. Results: Through the establishment of the traceability management process system of implanting medical supplies, the standard management mode of the medical supply technique will be attained. Even when the information is incomplete, we can retrieve and trace back quickly. Therefore, the goal of controlling the adverse events of medical implants, reducing medical risks can be achieved. Conclusion:the discussion above can be taken as a reference to the standardization of the management of implantable medical consumables.
ABSTRACT
In order to further research into the EEG information of rats epileptic model, we applied different nonlinear dynamic methods. After having analyzed the EEG signal of rat falling sickness by means of approximate entropy and correlation dimension, we adopted a the new method, unstable periodic orbits, which was used to analyze complex activity of neurons system to look for the change regularity of change in the EEG signal in the whole course of rat's falling sickness. We found period 1 orbits and period 2 orbits to be statistically significant in the data of ictal time of epilepsy. At the same time, we found period 1 orbits to be statistically significant in the data of preictal time of epilepsy.

Based an ordinary ECG, this paper deals with a portable monitor system able to measure the values of QRS. With a liquid crystal display (LCD), this monitor is suitable for China's special condition. Besides developing the overall scheme of the system, this paper also performs the designs for the hardware and software. The 80196 single chip microcomputer is taken as the central microprocessor to process and analyze the realtime ECG signals. With the performances of the ordinary monitor, this monitor also has such functions as arrhythmia analysis, HRV analysis, alarm, self-freeze and paper self-advance. Being convenient to carry, this monitor can be powered by alternate current (AC) or direct current (DC). Stability, low power consumption and low cost are emphasized on in the hardware design and structured design is applied to the software design. With a high versatility and a low cost, this monitor has a valuable reference to China's monitor.
ABSTRACT
The number of detector rows has been the focus of the CT development for decades.During the last decade,CT development has reached a threshold which is represented by coverage,mechanics,resolution and dosage.In order to break this bottleneck,two further development directions have been shown in recent years,of which,one is to increase the number of the detector rows,and the other is to revolutionize the material of detector to explore new clinical applications.Generally,HDCT opens the new era for whole CT modality,bringing the radiologists the high-resolution image,spectral imaging,large coverage and low dosage application.
