ABSTRACT
Using the new negative pressure biopsy technology, the automatic negative pressure gun and the specific puncture needle for the biopsy have been developed. Renal biopsies were conducted in 1136 cases, with the success rate being 99.9%, and 29 cases gross hematuria while the hepatic biopsies were conducted in 16 cases, mass biopsies in 3 cases with the success rates being 100% respectively. The biopsy gun has the advantages of easy manipulation, higher success rate and lower incidence of complications.

With wide range applications of the ultra-large-scale integrated circuits, multilayer circuit board and components surface welding technology, clinical medical engineers have been confronted with challenges in the service and maintenance of largescale medical equipments and the traditional model has faced the great challenges too. The clinical medical engineers should be actively get involved in operation, maintenance and service of large-scale medical equipment, in the same time; it's necessary for buying suitable service supply, protecting the smooth function of large- scale equipment and meets the clinical needs.
ABSTRACT
In tendering-based purchase of medical equipment, the specifications and parameters in tendering documents are the key factors. This paper presents the way to compile related document on the basis of the experience.
ABSTRACT
As the development of clinical medicine has depended on modern medical equipment increasingly,clinical medical engineers have become the bridges between modern clinical medicine and engineering.They keep the normal running of hospitals and promote the hospital modernization.The equipment service & maintenance isn't the only responsibility of medical engineers.In fact,engineers should be responsible for all medical activities relevant to engineering equipment.The main tasks of engineers should shift from the equipment service & maintenance to the application safety and quality control in the whole process of the equipment usage,which include equipment application safety and risk control,failure service and preventive maintenance,quality control and management,measurement and monitor of adverse event,etc.
ABSTRACT
Utilizing micro-pump and under the control of SCM,the tourniquet can automatically control antimemorrhagic pressure,antimemorrhagic time and loosing time.It is suitable for the automatic hemostasis of limbs.There are two working modes for medical service staff to select including air automatic inflation & releasing mode and manual air releasing mode.A new design of the sleeve bandage enable the wounded arms and legs use the same tourniquet.It is easy and convenient to release and repressurizing,which is suitable for the wounded to self operated.
