Description

Nuclear pollution wounded personnel decontamination device

Technical Field

The utility model relates to a nuclear pollution wounded person washes and disappears technical field, in particular to nuclear pollution wounded person washes device that disappears.

Background

The nuclear and nuclear radiation events comprise six types of events such as nuclear accidents, radiation accidents, nuclear terrorist attacks, nuclear weapons and radioactive weapon attacks, and military equipment radioactive substance leakage, such as nuclear wars, nuclear attacks, various nuclear power station leakage accidents, and nuclear terrorism events (such as terrorist attacks on nuclear facilities or uses of small nuclear weapons for terrorist attacks and the like), and are characterized by wide influence range, more injured people, serious casualties, extremely complex casualties and the like. After a disaster occurs, the rescuers can arrive at the scene in the first time, radioactive pollution to wounds and other parts of the wounded is eliminated as soon as possible, further damage of radiation to human bodies is reduced, early medical treatment and treatment are carried out on the radiation wounded or non-radiation wounded, meanwhile, adverse effects of the radiation on the rescuers or surrounding people are prevented as far as possible, and the method becomes a core task of on-site medical treatment. At present, the common scheme is to send the wounded and set up a plurality of decontamination tents to complete decontamination in sequence and one-way. However, the rescue tent is difficult to be unfolded as required due to the limitation of the site environment, the wounded person is easy to get worse in the transportation process, the secondary injury of the rescue person can be caused due to the difficulty in effective isolation in the decontamination process, and the like, so that the improvement of the medical treatment capability of the disaster site is restricted.

The nuclear pollution wounded personnel are cleaned in two ways, one is local decontamination, and the other is whole body decontamination; general decontamination is generally directed at wounded seriously injured persons, even unconscious wounded persons, and a horizontal type individual decontamination device is adopted for decontamination of the wounded persons: the movable barriers are arranged on two sides of the decontamination bed in a false mode, a sewage guide device is additionally arranged under the bed, rescue workers use a spraying system arranged on a tent to carry out decontamination work on wounded persons, after the wounded persons are lifted to the decontamination bed, the barriers on two sides and the front and the back are erected to form a semi-closed area, the rescue workers carry out whole-body decontamination on the wounded persons, and sewage is conveyed into a sewage collecting bag through guide water channels on two sides of the decontamination bed. After the decontamination is finished, the enclosure is put down, the wounded person is transferred to a cleaning stretcher for rechecking and back-feeding, and then the decontamination bed is cleaned by the rescue personnel. The decontamination equipment can rapidly complete the decontamination work of wounded personnel, can rapidly complete the self-cleaning requirement of equipment, and simultaneously avoids the diffusion of nuclear pollution wastewater. But this equipment also has fatal defects: the equipment is simple and crude, rescue personnel are required to participate in the whole process, and the risk that the rescue personnel are polluted by nuclear pollution exists.
