Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a radiation protective clothing with good mobility suitable for handling radioactive materials and performing surgery using a surgical X-ray apparatus for use in a medical dormitory, for example.

Traditionally, radiation protective clothing has been used in addition to surgical clothing, as well as jacket-type clothing without sleeves, apron-type clothing that covers the abdomen from the chest, and skirt-type clothing that protects the lower back, in order to improve the body's mobility when worn. However, the fabric sheets that make up these protective clothing are thick and flexible, but they lack flexibility and are stiff, so when you work while wearing them, your movements are severely restricted and the material is radioactive. Handling of materials, surgical operations using X-rays, etc. have caused great inconvenience in mobility, especially when sitting on a chair, standing up, or walking.

The present invention provides a radiation protective clothing with good mobility when worn without impairing the radiation protection ability inherent to the protective clothing.

The inventors believe that the poor mobility of conventional protective clothing is due to the fact that even when formed from multiple laminated sheets,
Because the sheets are adhered, or the peripheral edges are sewn, or the edges are fixed all around by gluing, fusing, etc., they act as an integral thick sheet, and even though each laminated sheet has flexibility, the sheet as a whole It was discovered that this lacked flexibility, and the present invention was completed in order to improve this.

The gist of the present invention is to form protective clothing by overlapping at least three layers of soft polymer films having radiation shielding ability and hemming and fixing the outer edges. The radiation protective clothing has a structure with good mobility, characterized in that the peripheral edge of the film is formed in a parallel shape slightly inside the outer edge, and has a free peripheral edge that is not combined with the front and back films.

That is, in the present invention, by making the inner layer film periphery of the movable part when wearing the protective clothing a free periphery that does not combine with the front and back films, the flexibility of this part of each protective clothing is ensured. , the inner layer film maintains its independence from other films with a thin air layer in between, and has flexibility according to the thickness of each film, and the flexibility of these films as a whole is equal to the sum of the thicknesses of these films. It is much more flexible than an integrated sheet of the same thickness and weight. For example, in the case of apron-type protective clothing that protects the chest and upper extremities, the chest and abdomen do not move much during work, but the parts of the body from the groin to the upper extremities that are mobile This refers to the area where the sheet moves a lot and frequently due to the movement of the seat, and the same applies to other areas of protective clothing where there is a lot of movement.

The protective clothing is made of a soft polymer film capable of shielding radiation, such as soft polyvinyl chloride, ethylene vinyl acetate copolymer, soft polyurethane resin, etc., containing lead powder or the like and formed into a film shape. Although the film thickness is preferably thinner from the viewpoint of flexibility, it is determined by taking into account film strength, lead equivalent, etc. Three or more of the films obtained in this way are stacked to give the desired lead equivalent,
Cut into protective clothing shapes. At this time, the movable portion of the film that will become the inner layer is cut at its periphery in parallel so that it is inside the periphery of the front and back films. The front, back, and inner layers are stacked together, and the movable part of the inner layer film is used as a free periphery, and the periphery is fixed by sewing or high-frequency welding, etc., and an attachment band, etc. for wearing is attached to form a product. .

As an example of such protective clothing, a front view of an apron-type protective clothing is shown in FIG. 1, and a side view with the movable part cut away is shown in FIG. In the figure, 1 is a front film, 2 is a back film, 3 is an inner layer film (in the drawing, there are two inner layers), and 4 is a peripheral fixing portion.

In addition to the apron type mentioned above, it can be applied to parts of protective clothing that require mobility, such as the lower hem of surgical gown-type protective clothing, the lower part of sleeveless vests, and the lower half of rolled skirts.

Since the present invention has the above-mentioned configuration, unlike conventional protective clothing, it does not impair the necessary radiation protection ability, each film exhibits independent flexibility in the movable part, and the periphery has two sides. Since the sheets are stacked on top of each other and become thinner, they are highly movable, and the inner layer film's movable part runs parallel to the outer edge slightly inward, so it can be easily attached, detached, and cleaned unless it is handled roughly to disturb the interior. It can hold its position and withstand long-term use, making it extremely useful as radiation protection clothing.
