ABSTRACT
Objective To design and develop an air purification system for intensive care ambulances,which can effectively purify the air in the compartment and sterilize the microbes in the air.Methods By integrating titanium dioxide photocatalysts with air filtration materials,an air purification system was designed that was capable of effective sterilization of microbes in the air via photocatalytic oxidation and decomposition,and of effective filtration of particles in the air through HEPA filters.The protection effect was evaluated by air filtration and sterilization tests in accordance with the related national standards.Results The air cleanliness could reach the 100 000 level with bacteria counts no more than 1 CFU per pan for 15 minutes in the ambulance compartment when the air purification system worked normally,which could meet the demands of environmental hygienic standards for intensive care units.Conclusion The air purification system can effectively purify and sterilize the air in the compartment of an intensive care ambulance.The effects of air purification meet the requirements of related hygienic standards,which can satisfy the demands of treatment and intensive care for the victims in the ambulance.
ABSTRACT
Objective To develop an intelligent system which is able to offer an optimized emergency treatment recommendation for fast triage automatically.Methods An algorithm and intelligent platform for grading injury were developed based on physiological signal collecting technology, intelligent grading algorithm and integration technology.A comparison between this system and traditional methods was made.Results This intelligent system was able to increase accuracy by 21%and took only 48%of the time taken by traditional methods.There was significant difference between the two groups(P=0.038<0.05).Conclusion The accuracy of the triage is improved by this intelligent system that is less time-consuming.With this device, the injury statement can be identified quickly and the targeted medical treatment can be performed accurately.The efficiency of emergency treatment in case of disaster will thus be dramatically increased.
ABSTRACT
This paper introduces a small and light one-handed electronic tourniquet which adds the function of electronic timing and alarming to the traditional locked tourniquet. The tourniquet has an effect on first aid hemostasis from extremity wound in emergency.
ABSTRACT
Objective To design an integrated emergency medical treatment system mounted on helicopter, which can meet the requirements of field treatment and evacuation in emergency disasters or local wars, the system has immobile form and mobile form. Methods With the characteristics of existing helicopter considered, the components of the system were supposed to include a universal stretchers, overall structure and embedded emergency devices and support transport accessories. Results The system could realize the destination of swift response and air-and ground first-aid, the new model of swift response can made the regulation and principle of first -aid more reasonable, and increases the survival rate significantly. Conclusion Critical diseases have become the latest killer in daily life. The first-aid on spot need the new model of swift response and air -and ground first -aid, the system can decrease the invalidity and mortality.
ABSTRACT
Objective To solve problems existing in multichannel digital temperature detecting system,including boring wiring,unreliable data storage,poor anti-jamming.Methods Dynamic address code design and automatic compositor algorithms were integrated into the software design,while the running out was eliminated by adopting watch dog chip.Results The validity of the improvement were proved by high & low temperature tests.Conclusion The improved system,with convenient wiring,reliable data storage,accurate results and short response time,can be applied to fully digital & unattended temperature detection.
ABSTRACT
This paper introduces a novel trousers,whose theory is to drive blood by inflated pressure.Being light-weight,small and effective,easy to carry,store and operate,it is postured for first aid and resuscitation of hospital patients with severe shock,and also can be applied to bleeding remission,hemorrhagic as well as fracture immobilization.
ABSTRACT
This paper introduces a type of anaesthesia workstation which is composed of two vertical medical chests, i.e. the upper and lower parts. Taken out of the chest, the two parts are butted against and locked to make the workstation ready for operation. After operation is finished, the two parts are uncoupled and put into the chests, and then the workstation can be stored and transported with the chests closed.
ABSTRACT
The multi-channel digital measurement technology for temperature is developed on the basis of the combination of digital measurement technology for temperature and the 1-wire technology. This paper discusses this technology and applies it to designing a system for multi-channel digital temperature measurement. This system has already been used in the research of some kind of medical equipments. It can conquer such problems as overhigh consumption of time and labor, difficult condition when applied to measuring microenvironment temperature within a cold or hot zone.
