ABSTRACT
Objective To explore harmless disposal method and equipment for the medical waste in the mobile hospital. Methods The characteristics and harmless disposal methods were analyzed,and then a pyrolysis scheme was proposed for the medical waste in the mobile hospital.The scheme took considerations on equipment miniaturization,vehicle mounting as well as gas cleaning. Results A medical waste pyrolysis vehicle was developed for the mobile hospital, which had the performances met the requirements of 300 persons/d casualty throughput,environment protection and etc.Conclusion The developed vehicle can be used for harmless disposal of the medical waste in the mobile hospital, and is worthy promoting practically.
ABSTRACT
Objective To develop a new NBC casualty decontamination shelter,which can be used to decontaminate NBC casualties. Methods The shelter integrated the technologies of plate shelter expansion, auto waterway control, micro-environment control, rapid sewage collection and etc, and took considerations on decontamination requirements of the ambulatory and non-ambulatory casualties.It was designed combining fixed and extendable shelters,which realized double-side expansion by manual push and pull. The shelter was composed of the plate shelter, decontamination devices and facilities, water supply & heating system, waterway system, power supply and distribution system, lighting system, air conditioning and heating system and other accessories.Results The shelter could decontaminate the ambulatory and non-ambulatory casualties simultaneously,the decontamination water temperature ranged from the temperature of water source to 50 ℃, the mixing ratio of the decontamination water was from 0.2% to 2%, and the time consumed for deployment and withdrawal was not more than 20 min. Conclusion The shelter gains advantages in layout and technology, and enhances decontamination ability for NBC medical rescue.
ABSTRACT
Objective To find out the iodine nutritional status and thyroid function of pregnant and lactating women in the urban areas of Wuwei City of Gansu Province,and to provide a scientific basis for iodine supplementation.Methods Blood and urine samples of pregnant (52 persons) and lactating women (59 persons) were collected in 2009.Urinary iodine content was measured with arsenic cerium catalytic spectrophotometric.Serum free three triiodothyronine(FT3),free thyroid hormone(FT4),triiodo thyronine(TT3),serum total thyroxine (TT4) and thyroid-stimulating hormone (TSH) were detected with direct chemiluminescence immunoassay.Results The medians urinary iodine of pregnant and lactating women were 274.68,217.88 μg/L.The rates of low urinary iodine (pregnant women below 150 μg/L,lactating women lower than 100 μg/L) were 9.62％ (5/52) and 6.78％ (4/59).Serum TT3,TT4 levels in pregnant women[(2.48 ± 0.59),(132.18 ± 33.36)nmoL/L] were higher than that in the lactating women[(2.16 ± 0.49),(108.79 ± 28.36)nmol/L,t =-3.123,-3.971,all P ＜ 0.05].Thyroid dysfunction incidence rates of pregnant and lactating women were 17.31％ (9/52) and 8.47％ (5/59).Thyroid dysfunction was mostly subclinical hypothyroidism.Conclusions Overall iodine nutrition of pregnant and lactating women is in good condition,some individuals have the trend of hypothyroidism.It is necessary to carry out routine monitoring of urinary iodine and thyroid function.
