Blood temperature-varying has been widely applied in clinical practice such as extracorporeal circulation for whole-body perfusion hyperthermia (WBPH), body rewarming and blood temperature-varying in organ transplantation. This paper reports a novel DCS (Computer distributed control)-based blood temperature-varying system which includes therapy management function and whose hardware and software can be extended easily. Simulation results illustrate that this system provides precise temperature control with good performance in various operation conditions.

Microneedles array based on micro electro-mechanical system (MEMS) technology is one of important applications in biomedicine and brings a new means in biomedicine field. The prospect for the development of microneedles technology in precision drug injection, clinical monitoring and biochemistry test is and save broad. This paper describes three important applications of MEMS microneedles array in biomedicine field: biomedicine microneedles electrode, transdermal delivery of drugs and fluid extraction, and then summarizes their application elements and recent development. It explains the characteristics of microneedles, which provide painless, effective and save biomedical method in accordance with human requirements. In addition, a series of the fabrication technology of microneedles array is discussed.

Micromachining of capillary electrophoresis chips is described.The current in channels was determined versus the voltage applied on the chip.Using laser-induced fluorescence detection,the process of injection and separation on chips was recorded with charge-coupled device(CCD).With defferent voltge of reservoirs on glass chips,profiles of the sample plug were studied. The elctropherogram of hydrolysis product of fluorescein isothiocyanate (FTTC-OH) and arginine labeled by fluorescein isothiocyante(FTTC-Arg) was obtained.
ABSTRACT
This paper designs a new distributing structure of nozzles in medical micro-jet device on the bases of emulating results. This new structure can improve the output coefficient and flux of drug delivery. Then, a micro-jet device is fabricated by MEMS technology based on this structure. The experiment results indicate that the number of output droplet is approximated to normal distribution on droplet diameter and velocity. Moreover, the droplet velocity and the flux are both improved in this new micro-jet device, whose values are 2.93m/s and 11.77?l/s respectively.
