Meanwhile, the decontamination bag is in a closed state, so that the secondary contamination can be effectively prevented.
Example 2:
on the basis of example 1, if contaminant residues are not completely eliminated, the nuclear contaminated skin is decontaminated using a second decontamination mode of the system. When the first decontamination mode cannot achieve the expected effect, in order to avoid skin damage caused by repeated long-time water flow action and the skin surface, the second decontamination mode of the system is used for continuing decontaminating the nuclear contaminated skin, decontaminating agents are injected through the liquid inlet by using decontamination dressing, and the decontaminating dressing is fixed on a local part by using a local soaking method. Further local decontamination wherein in this embodiment the decontamination machine is the same as in embodiment 1, no further description is given here.
Fig. 4 is a schematic view of a construction of a decontaminating dressing according to an embodiment of the present invention. As shown in the figure, the decontaminating dressing includes a waterproof film 41, a water-absorbing layer 42, and a release protective film 45 which are laminated in this order. The waterproof film 41 is covered over the water-absorbing layer 42, and a space 411 (dressing cavity) for containing a decontaminating liquid is formed therebetween. At least one input connector 43 and at least one output connector 44 are fixedly arranged on the waterproof film 41, wherein the input connector 43 is used for guiding external decontamination liquid into the space, and the output connector 44 is used for guiding the decontamination liquid in the space.
The input connector 43 and the output connector 44 are pipe connectors and are made of the same or different materials with the waterproof film. The pipe joint can be integrally formed with the waterproof film 41 or fixedly connected into an integral structure by means of heating connection, bonding and the like.
Wherein the coupling includes a cap that can close or open the coupling external interface. The cap may be connected by a flexible portion near the coupling external interface.
Referring to fig. 5 and 6, an annular adhesive layer 412 is disposed on the periphery of the lower surface of the waterproof film 41, and the edge of the release film 45 is connected to the waterproof film 41 through the annular adhesive layer 412.
When the release film 45 is peeled off and the waterproof film is attached to a predetermined portion of the body through the annular adhesive layer 412, a water-tight space is formed between the waterproof film 41 and the predetermined portion of the body.
The waterproof film 41 is made of a transparent material or an opaque material, and a window formed of a transparent material is provided at a predetermined portion so as to facilitate the user to observe the decontaminating liquid state in the space 411 from the outside.
In some examples, the water absorbent layer includes a polyurethane foam layer 421 on an upper layer and a mesh layer 422 on a lower layer. The polyurethane foam layer 421 has a predetermined porosity, and the decontaminating liquid in the space 411 may be uniformly applied to the lower mesh layer 422 through the pores, thereby wetting the mesh layer 422 and achieving wet dressing of the affected part.
The release protective film 45 comprises two sheets which are stacked, wherein the release protective film on the upper layer covers a first part of the lower surface of the waterproof film from one side, the release protective film on the lower layer covers a second part of the lower surface of the waterproof film from the opposite side, and the first part and the second part have overlapping areas. Because the overlapping area is arranged, the part of the second part positioned in the overlapping area forms a free side edge, and when the second part is convenient for a user to use, the second part is torn off through the free side edge.
The external dressing system can be formed into a generally square, round or elongated sheet structure depending on the body location to be decontaminated, and can be sized as desired to facilitate application to different body locations.
When the second decontamination mode is used for decontamination, the release protective film 45 is firstly torn off, and the annular adhesive layer 412 is used for pasting the invention on the affected part. Then, the lid of the input connector 43 is opened, the decontamination dressing system connector is connected with the decontamination machine interface, the decontamination machine is started by operating the key, and the decontamination liquid enters the decontamination dressing system and acts on the skin surface of the human body through the circular opening. The decontaminated liquid is recycled to a liquid recycling container of the decontaminating machine.
The supply and discharge times and flow rates of the decontamination solution can be controlled by the decontamination machine. For example, after a predetermined time, the concentration of the injected decontamination solution is reduced, the topical decontamination is ended, or the decontamination is continued, but the decontamination solution in the space 411 is drawn out due to contamination of the solution caused by the release of impurities from the affected part into the solution in the space 411 through the water absorbing layer. During the extraction process, if the liquid medicine is not extracted smoothly due to the large negative pressure in the space 411, the cover of the input interface 43 can be unscrewed or opened to realize pressure balance.
When the decontamination mode is used for decontamination, the decontamination machine can be controlled to decontaminate the nuclear contaminated skin for a long time with smaller flow and pressure, so that the damage effect of residual pollutants on the skin surface is eliminated by slow decontamination, and the decontamination method has the advantages of thorough decontamination, mild effect and small damage to the skin.
According to another aspect of the present invention, there is also disclosed a method for decontaminating nuclear contaminated skin using the automatic nuclear contaminated skin decontaminating system, comprising:
step 701, fixing the decontamination bag on the surface of the nuclear contaminated skin, and decontaminating the nuclear contaminated skin by using the first decontamination mode;
step 702, judging whether the decontamination effect meets a preset requirement;
the step may be performed by a worker observing the decontaminating portion or by detecting with a detecting device to obtain a determination result, for example, by acquiring an image of the decontaminating portion and recognizing the image to output a determination result of the decontaminating effect.
Step 703, fixing the decontamination dressing on the surface of the nuclear contaminated skin, and decontaminating the nuclear contaminated skin by using the second decontamination mode;
and if the decontamination effect does not meet the preset requirement, fixing the decontamination dressing on the surface of the nuclear contaminated skin, and decontaminating the nuclear contaminated skin by using the second decontamination mode.
The decontaminating liquid used in the first decontaminating mode has different components from the decontaminating liquid used in the second decontaminating mode, for example, the decontaminating liquid used in the first decontaminating mode has a more efficient decontaminating effect, and the decontaminating liquid used in the second decontaminating mode is milder and has no or less harm to human skin.
The method comprises the steps of firstly using a first decontamination mode to decontaminate nuclear contaminated skin, namely rapidly decontaminating nuclear contaminated skin at a larger flow rate and pressure (or flow rate), so as to eliminate or reduce the damage effect of most pollutants on the skin surface in a short time, and then using a second decontamination mode to decontaminate nuclear contaminated skin at a smaller flow rate and pressure for a long time, slowly decontaminating and eliminating the damage effect of residual pollutants on the skin surface, so that the thorough decontamination of pollutants is realized in a relatively mild mode, and the damage to the skin is small.
The above embodiments are only for illustrating the technical aspects of the present invention and not for limiting the same, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that: modifications and equivalent substitutions can be made to the specific embodiments of the present invention or to some of the technical features without departing from the spirit of the technical solutions of the present invention, and they should be covered in the scope of the technical solutions claimed in the present invention.
