ABSTRACT
Percutaneous nephrolithotripsy is the first line treatment for complete staghorn calculi, but there are risks such as renal function damage, bleeding, and infection. A case of complete staghorn calculi 8.3 cm×4.5 cm and mean CT value of 1 321 HU was reported. Urine culture suggested proteus mirabilis infection. The patient was given sensitive antibiotics for 3 days, and was treated with one session of natural orifice transluminal endoscopic lithotripsy with intelligent control of renal pelvic pressure. KUB on the first postoperative day showed residual stones of 1.0 cm×0.5 cm. There were no complications.
ABSTRACT
When the conventional massage assembly is running, the massage intensity is not monitored, the massage effect is not ideal, and there are hidden dangers. In this paper, a new type of massage assembly is designed, which can measure and control the intensity of massage in real time. The result of the prototype test shows that the design achieves the desired effect. The newly designed massage assembly has a high degree of intelligence, and has obvious breakthrough in the aspects of safety, comfort, massage curative effect and service life.

Objective To evaluate the efficacy and safety of suctioning flexible ureteroscopy with automatic control of renal pelvic pressure in the treament of intrarenal and proximal ureteral stones.Methods From November 2014 to December 2016,a total of 372 patients,including 200 males and 172 females,with upper urinary tract calculi were studied.The average age of patients was 48.1 years old.The average size of stone was 5-35mm,mean 15.7mm.There were 272 cases of renal calculi,80 cases of ureteral calculi and 20 cases of renal calculi combined with ureteral calculi.There were 252 cases of single calculi and 127 cases of multiple calculi.There were 237 cases of urinary tract infection and 14 cases of bacteremia.All patients were treated by suctioning fiexible uretemscopy with automatic control of renal pelvic pressure by a patented intelligent system including an irrigation and suctioning platform and a ureteral access sheath with a pressuresensitive tip.Statistical analysis was performed regarding renal pelvic pressure,operative time,stone-free rates,and complications.Results Three hundred and thirty of 372 patients only accepted one surgery to remove the stone.There were 12 cases of upper ureteral calculi were converted to ureteroscope lithotripsy.Seventeen cases were converted to percutaneous nephrolithotomy due to significant ureteral stenosis.Seven cases who failed the first surgery due to difficulty in placing the ureteral access sheath but flexible ureteroscopy were successfully performed in these patients after indwelling a D-J stent for 2 weeks.No stone was found in 6 cases,and the soft endoscope of ureter was examined.In all patients,the renal pelvic pressure of the pelvis was controlled within 20 mmHg.The average operative time was 15-180 min(mean 58.9 min).The stone-free rates was 95.55％ (322/337),the incidence of postoperative fever was 2.97％ (10/337),the sepsis rate was 1.19％ (4/337),the incidence of urinary sepsis was 0.89％ (3/337),the incidence of lumbago caused by extravasation was 0.59％ (2/337),and no peripheral viscera injury or death case.There was no statistically significant difference between preoperative and postoperative white and red blood cells (P ＞ 0.05).Conclusions This new type of suctioning flexible ureteroscopy with intelligent pressure-control has the advantages of perfusion attraction,pressure feedback,intelligent control and visualization of intracavity pressure.It could be a new type of operation with high safety,low complication and high stone free rate.

ABSTRACT
En este artículo se presenta el diseño de un control de temperatura con técnicas de protección inteligente, con la finalidad de implementarlo en incubadoras para recién nacidos. El funcionamiento del control de temperatura se centra en la utilización de un microcontrolador, programado para responder por modulación de ancho de pulso sobre el calefactor, y así lograr una alta precisión en la regulación de la temperatura. Lo novedoso del proyecto radica en la técnica de protección utilizada. Esta técnica está basada en la supervisión constante de las irregularidades térmicas, en múltiples puntos del ambiente de la incubadora. Esto permite establecer un criterio para el apagado del calefactor y la activación de la alarma en función de la lectura individual de 4 sensores tipo termistor NTC, ubicados estratégicamente dentro de la incubadora. Este diseño se ve motivado a la necesidad de adaptar controles modernos a incubadoras antiguas que pueden ser totalmente recuperadas, además abre la posibilidad de diseñar un equipo de incubadora completo. Cabe destacar que este proyecto contribuye con el desarrollo de tecnología propia en el área de la instrumentación y control aplicado a ingeniería biomédica.
This paper presents an intelligent temperature control design with smart protection techniques, implemented in newborn incubators. The operation of the temperature control was focused on the use of a programmed microcontroller, which respond with pulse width modulation at the heater, and thus achieve, high precision temperature regulation. The novelty of this design, lies, on the protection technique used. That is based, on a constant monitoring of the incubator thermal variations; at several parts of the environment. That allows establishing, an approach for the shutdown of the heater and the alarm on, depending on the individual reading of 4 sensors NTC thermistor, strategically located within the incubator. This design is motivated by the necessity of adapt modern controls to old incubators that can be fully recovered; also opens the possibility to design a complete new incubator. It is important to note that this project contributes with our own development technology; especially on biomedical engineering, instrumentation and control.

@#ObjectiveTo investigate the necessary of letting the intelligent knee joint be adaptive to the road terrain and the key technology of knee moment control method. MethodsBased on data from gait analysis and the dynamic model of lower limb,the knee moments while people walking on the path of different terrain were obtained. Terrain identification method was based on the features of electromyography(EMG) signals of the thigh,and the EMG of some muscles was detected. The methods were applied to an intelligent trans-femoral prosthesis developed for tests in the laboratory.ResultsConsiderable variation of the knee moments appeared when people walking on the path of different terrain,as well as that of the features of EMG of some muscles.ConclusionIt is necessary to make the intelligent knee joint be adaptive to the road terrain,and it is possible to be achieved with satisfied motion of the leg and the trajectory of ankle joint by the intelligent transfemoral prosthesis being studied which can identify the features of EMG signals.
