Description
Technical field
The utility model relates to a kind of whole-body type positive-pressure biological protective clothing of built-in air-supply, is exactly the built-in and whole-body type positive-pressure biological protective clothing of integral waterproofing of a kind of supply air system.
Background technology
Along with increasingly rampant, the acute epidemic situation of bio-terrorism and the frequent appearance of public health emergency, both at home and abroad to the R&D intensity of high-risk biological pollution operating personnel protective garment also in further increasing.The biological protective clothing having formed at present product is of a great variety, can for different personnel in different occasion, but the security of most of biological protective clothing can not meet the requirement of shelter of the high-risk biological pollution environment such as bio-safety more than three grades laboratories.In order to improve the security of biological protective clothing, malleation guard technology is also used to develop the biological protective clothing of high security, has become the important equipment of operating personnel's protection under high-risk biological pollution environment and radioactive pollution environment at present.Positive-pressure biological protective clothing also claims formula protective garment of supplying gas, it is the special protective garment that the functions such as protection head, face, health, hand, pin and respiratory system are integrated in one, its main feature be in protective garment gas pressure higher than environment atmospheric pressure, being issued to the high protection level to harmful substance in the effect of external and internal pressure difference, is that blocking-up personnel are leaked cruelly in the dangerous direct physical barrier such as aerosol, bioaerosol, radioactive ash, splashings and unexpected contact.
Positive-pressure protective clothes can be divided into the large class of the electric air-supplying positive-pressure protective clothes two in compressed gas source central gas supply long-tube positive-pressure protective clothes and self-powered source, is usually made up of four parts: integrated protective clothing up and down, replaceable protective gloves (shoe cover) and air supply system that head-shield, gastight material that transparent gastight material is made are made.Because air supply system provides pure air in positive-pressure protective clothes, the existence of inside and outside positive differential pressure makes the poisonous and harmful substance in external environment cannot enter protective garment inside in addition, the protection that therefore in positive-pressure protective clothes, personnel will be subject to all the time compared with high safety grade.During positive-pressure protective clothes work, the existence of internal stability air-flow also makes protective garment internal heat be able to scatter and disappear in time, has good overall thermal comfortableness.During positive-pressure protective clothes work, personnel enter protective garment from airtight slide fastener, dress well and zip up, after opening air supply system, positive-pressure protective clothes expands gradually, internal gas pressure rises gradually, reach air quantity while forming certain positive differential pressure with external environment and also reach stable state, the air-flow after ventilation will be discharged from air bleeding valve.
Patent CN1449697A describes a kind of epidemic safety clothing, is the coverall suit that a kind of head, jacket and trousers are connected as a single entity, and with electric feeding device of air, protective garment inside can be made to have certain malleation.This utility model cuff and the bottom of s trouser leg adopt the mode of elastic cord sealing, poor sealing performance, with the connection defective tightness of gloves and boots with reliable.
Patent CN1513667A describes a kind of protective materials and medical protective garment, positive pressuring type head protecting cover, protective materials is the composite that TPU and fabric are composited, the protective garment air-tightness be made up of it is good, can malleation be formed under the supplying gas of power supply air system, there is good barrier propterty.The mode that this protective garment adopts head-shield to be separated with protective garment, cannot form malleation at whole body, only have the local malleation of head, therefore security and comfortableness are all a greater impact.
Above-mentioned patent is that the domestic Researching and practicing to positive-pressure biological protective clothing is attempted, and has the feature of certain positive-pressure biological protective clothing.But it still has larger gap with advanced foreign technology in overall construction design, malleation maintenance, human engineering and condition monitoring etc.
