5.Design and maintenance of the hospital-level external report.
Chinese Journal of Medical Instrumentation 2011;35(5):392-394
HIS external report provides convenience for statistical work in each hospital department, but the data of each department is not only relatively independent but also absolutely correlative. Besides, the numerous and complicated reports bring the hospital executive level inconvenience when they make a strategic policy. So the design of the hospital-level external report can resolve the problem mentioned above. Microsoft SQL Servers is used to write the procedures of external reports. We have written nearly 40 hospital-level external reports about outpatient, in-patient, medicine and etc., which satisfied the demand of the hospital leaders. This paper elaborates on the hospital-level external report in respects of: the design philosophy, the design process, and the maintenance tips and etc.?

Aiming at the low efficiency and low quality detection level of the manual infusion set, a gas detection system for infusion set based on STM32 single-chip microcomputer was designed. The detection system includes hardware system design and software system design. The hardware system is based on the STM32F103 single-chip microcomputer. It mainly designs the gas pressure sensor acquisition circuit and the multi-way solenoid valve control circuit. The software system uses a C ++ real-time operating system to ensure system monitoring's real-time performance and validity. Test data is transmitted to the upper computer and displayed via USB serial communication. The experiment proves that the infusion set gas detection system can perform gas detection on the infusion set. The system has the characteristics of stability and high accuracy. The relative error of the experimental measurement is within ±5%, and the detection efficiency is better than manual detection.

This paper designed a ventilator control system to control proportional valves and motors. It used LabVIEW to control the object mentioned above and design ,validate, evaluate arithmetic, and establish hardware in loop platform. There are two system' s hierarchies. The high layer was used to run non-real time program and the low layer was used to run real time program. The two layers communicated through TCP/IP net. The program can be divided into several modules, which can be expanded and maintained easily. And the harvest in the prototype designing can be seamlessly used to embedded products. From all above, this system was useful in employing OEM products.

Lung function monitoring is a critical technique for clinical medicine. Currently, the lung function testing devices used in our domestic hospitals are both expensive and bulky. A portable and accurate lung function parameters testing system is highly desired and is proposed in this paper. The hardware of the system is based on DSP technology. The breathing passage is designed with an aim suitable for the breathe and signal detection. We use the direct detection method to detect the gas flow, the breathing passage pressure and the breathing time. Thanks to the powerful data processing ability and the high operation speed of the DSP, breathing signals can be easily analyzed. Thus, several lung function parameters of clinical significance can be obtained. Experiments show that the accuracy of the system is better than 3%, and could meet the demand of the lung function testing.

PURPOSEDeveloping an exercise management software based on a smart phone to intervene wearer's exercise amount.
METHODUsing the Android system of mobile phone which contains acceleration sensor to detect the wearer's exercise amount, at the same time, the sensor send the information to the health management center.
CONSEQUENCEIt can carry out behavior intervention by the health management center's information feedback indication, thus guide the wearer to take exercise scientifically and safely to reach the most effective and appropriate exercising result, which realizes the system function.
CONCLUSIONThe behavior intervention based on Smart phones can apply as a new clinical measure to treat patients.

PACS (Picture Archiving and Communication System) is successfully applied in Huzhou Central Hospital, and is well integrated with its HIS system by WEBSERVICE middleware. The system supports DICOM 3.0 Standard, and DICOM gateways are installed for modalities that do not support DICOM so as to have implemented the digitalization of all the image departments in the hospital.
