Development of Correspondence Adapter Based on CAN

Chinese Medical Equipment Journal.2004;0(08):-.

Objective To transform the equipment with traditional RS232 interface into that with CAN connection interface.Methods On the CAN main line,node is the station for information receiving and transmission in the network.The intelligent node can establish the work way ID,the address and the baud rate through the programming.It is mainly composed by the singlechip and the programmable CAN correspondence controller.Results The hardware and software were designed.SJA1000 initialization,transmission and receiving subroutines are including in the software design.Conclusion CAN is a kind of excellent field bus with high reliability,low cost and has been applied in many fields.It has already formed the international standard and been viewed as one of the most widely used field buses in future.Lots of traditional equipment with RS232 interface are facing the problem of CAN interface transformation.

SUPERVENTRICULAR TACHYCARDIA THERAPY APPARATUS

Zhengxiang ZHU

Chinese Medical Equipment Journal.1989;0(04):-.

Clinical Practice verified that the esophagusatrial pace technique canbe used to treat superventricular tachycardia,but the therapeutic effect is not ideal to atrialventricular node reentrant tachycardia.We adopted intraheart electronic pulse stimulation which could get satisfactory effect.It is considereb that it is a new the- rapeutical method of superventricular tachycardia.

Field portable transfusion device

Bing WAGN ; Hong TANG

Chinese Medical Equipment Journal.2003;0(12):-.

A field transfusion device without support is designed.It is in shape of cuboid,and the idler wheels of mean axis disc are driven by motor to push transfusion liquid into human body.A disc with 6 idler wheels on the edge is set in the motor axis.When motor starts,idler wheels take turns to extrude liquid from transfusion pipe to human body with transfusion speed decided by motor rotate speed.Besides,an adjustable transfusion controller,sensor for liquid pressure and transfusion alarm system are equipped.When the set transfusion volume is finished,it gives alarm.

Chest X-Ray Projection Methods in Newborns

Liangjun CHENG

Chinese Medical Equipment Journal.2003;0(10):-.

Objective To improve chest X-ray images quality in newborns. Methods To improve the routine projecting position and adjust X-ray projection dose. Results Two sides of lung fields were well-displayed,and lung veins were clear. Meanwhile the contrasts between ribs and lung fields were good and cardiac size was not changed obviously. Conclusion Comparared with routine projection methods, the image quality has greatly improved on the aspectes above.

Quality Control of Molybdenum Target Radiography in Mammary Examination

Zhimin HU

Chinese Medical Equipment Journal.2003;0(10):-.

Objective 500 cases undergoing molybdenum target radiography were analysed retrospectively to improve the image quality. Methods influencing factors of 500 cases molybdenum target CR and clinical pathological data in recent 3 months were analysed. All of the patients take CC,MLO phtotography. The machine applied is Siemens 3000, AGFA galactophore special IP boards, and image postprocessor is AGFA ADC Compact. Results In 500 cases, 89 cases without obvious lesions, 389 case with benign lesion, 113 cases are breast cancer. Conclusion To take a satisfying molybdenum target radiograph, patients' features of breasts such as size and shape resulting in different radiation setting, which is the key to get satisfying images, should be understood.

Discussion on direct digital dual energy subtraction radiography and clinical application value

Jianxin CHEN ; Yongrong SHEN

Chinese Medical Equipment Journal.2003;0(12):-.

Objective To introduce direct digital dual energy subtraction radiography and explore it's clinical application.Methods The cases acquired separately by direct digital conventional radiography and direct digital dual energy subtraction radiography were compared.Results The detection rate,sensitivity and accuracy of calcifications in lungs,pulmonary nodules,stones in urinary system,calcifications of coronary artery and cardiovalvular were improved by using direct digital dual energy subtraction radiography.Conclusion Direct digital dual energy subtraction radiography is more valuable in clinical applications.
