Description

The present invention relates to a radiation protective garment worn by medical personnel for radiation protection, and more particularly to a radiation protection bra worn at the time of irradiation for radiation protection.

Conventionally, radiological clinics and others have been manufactured using radiation protection sheets containing lead that has radiation shielding properties, powdered antimony materials, bismuth materials, tungsten materials, etc. in order to avoid radiation exposure. Wearing radiation protective clothing. Further, there are cases where not only the medical radiation worker but also a person who enters the radiation examination room accompanied by the examinee and the examinee enter the room wearing radiation protective clothing in order to be exposed.

Conventionally, a coat type and an apron type are known as this type of radiation protective clothing (see, for example, Patent Document 1). As shown in FIG. 5, the coat-type protective garment has front body parts 12 and 13, a rear body part 14 and an arm hole part 15 which are divided into right and left at the center part, and an outer belt 16 passed through a belt loop on the outer surface side. have.

6 (a) and 6 (b), an apron-type protective garment 50 has a front body 51 and an arm hole portion 52, and a back surface portion 53 covers the shoulder ribs from both shoulders and armpits, It has a pair of left and right belt-like portions 55 that extend obliquely downward after crossing between the left and right shoulder blades, and is wound around the waist as a belt portion and overlapped with each other on the front side and connected with a fastener To use.

However, in the conventional radiation protection garments of the coat type and the apron type provided with the front part and the rear part, radiation may enter from the arm hole parts on the left and right side surfaces of the protection garment. In particular, when a woman with a large breast wears it, the protective clothing may be pulled in a convex shape due to the swelling of the breast, and the armhole part may open widely. The onset of this is a serious problem. However, it has been difficult to shield radiation entering from the armhole portion with conventional protective clothing.

Accordingly, an object of the present invention is to provide a radiation protective clothing (radiation protective brassiere) that reliably protects the mammary gland from exposure even if radiation enters through the arm hole portions on the left and right side surfaces of the protective clothing. As a result of thorough examination of the coat-type and apron-type radiation protective clothing having the armhole portion, the present inventors have worn the armhole portion by wearing a radiation protection brassiere under the radiation protective clothing having the conventional armhole portion. As a result of further finding out that it was possible to reduce the exposure of radiation entering from the present invention, the present invention has been achieved.

That is, the present invention is (1) upper and lower ends of radiation protective clothing in which sheet-like bodies are laminated and integrated on the front and back surfaces of a sheet-like radioactive protective body containing a thermoplastic resin and a powdery radiation shielding material. Alternatively, the radiation protective clothing is characterized in that a rubber-like body is attached to the end portion and fasteners are attached to both left and right end portions of the protective clothing so that the radiation protective clothing is detachably covered on the chest.

(2) The radiation protective clothing according to (1), wherein the portion covering the chest and the side is a substantially rectangular shape having a wide width.

In the radiation protective clothing of the present invention, the radiation entering from the armhole part of the conventional coat type and apron type radiation protective clothing is shielded by the radiation protective clothing worn under the radiation protective clothing. Radiation exposure can be reduced. In particular, when a woman wears it, even if the armhole is enlarged due to the swelling of the breast and a large amount of radiation enters the armhole, the radiation protection clothing (brass for radiation protection) that covers the chest and sides is exposed to radiation. Can be reduced. Further, since the radiation protective clothing of the present invention is worn under the conventional coat-type and apron-type radiation protective clothing, the conventional radiation protective clothing can be used as it is.

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a surface view of a radiation protection garment (radiation protection brassiere) 1 according to the present invention, FIG. 2 is a view showing a state wound around the body, and FIG. 3 is a cross-sectional view. FIG. 4 is a view showing a state in which an operator (substitute with a mannequin) wears the radiation protective clothing 1.

As shown in the cross-sectional view of FIG. 3, the radiation protective clothing 1 has a sheet-shaped body 3, 4 coated on the front and back surfaces of a sheet-shaped radiation protective body 2 containing a thermoplastic resin and a powdery radiation shielding material. ing. The sheet-like body 3 coated on the surface of the radiation protection body 2 may be colored, for example, in blue as shown in FIG. The sheet-like radiation protection body 2 and the sheet-like bodies 3 and 4 have flexibility so as not to hinder the operation of the radiation protection clothing 1. The sheet-like bodies 3 and 4 are polyolefin resin, polyvinyl chloride resin, polyurethane resin and other flexible synthetic resin sheets, natural fibers, woven fabrics of synthetic fibers, nonwoven fabrics, knitted fabrics, or synthetic resin sheets. It is the sheet | seat which coat | covered the fiber cloth on the upper surface and integrated. Although the thickness of the sheet-like bodies 3 and 4 is not specifically limited, Usually, it is about 0.01-1.0 mm. When the fiber cloth is laminated on the back surface of the radiation protection body 2, air permeability is slightly generated, the stuffiness is reduced, the sliding with the underwear is good, and the workability is also improved. Moreover, even if sweating, sweat is absorbed by the fiber cloth.

The radiation protection body 2 includes a thermoplastic resin and a powdery radiation shielding material, and the thermoplastic resin serves as a base material for the radiation protection body and also serves as a binder for a powdery metal material having radiation shielding properties. .

As the thermoplastic resin, for example, a polyolefin resin, a polyvinyl chloride resin, a polyurethane resin, or the like can be used. Among polyolefin-based resins, ethylene / vinyl acetate copolymer (EVA) is preferable because of good molding processability when formed into a sheet.

Examples of the metal material having radiation shielding properties include lead, tin, bismuth, antimony, zinc, tungsten, and oxides thereof. Barium sulfate can also be used. One metal material having radiation shielding properties may be used alone, or two or more metal materials may be used in combination. Lead is not preferred because it has a great adverse effect on the environment and the human body.

The average particle diameter of the metal material having radiation shielding properties is 1 to 300 μm. By setting the metal material in such a range, it is possible to exert an effect that the dispersibility with respect to the thermoplastic resin is good and the thermoplastic resin is easily adapted.

The radiation protector 2 is to be filtered for the purpose of removing undispersed materials after mixing the required amount of thermoplastic resin, radiation shielding metal and additives added as necessary, mixing with a mixing stirrer. Alternatively, a process such as vacuum defoaming is performed for the purpose of removing bubbles, and the obtained composition can be produced by molding into a sheet by a known means such as extrusion molding or press molding. Such a sheet-like radiation protection body 2 may be a single layer or a plurality of layers stacked.

The radiation protective clothing 1 having radiation shielding performance is obtained by cutting a sheet-shaped radiation protective body into a desired shape and wrapping it in a sheet-shaped body, or by bonding and integrating the sheet-like body on the front and back sides. It can be. When the radiation shielding body is sewn to the sheet-like body, an edge tape 5 is provided to protect the edge of the radiation protective clothing 1 as shown in FIG. 3 and the radiation protection body 2 and the sheet-like body are used using the suture thread 60. Sew 3 and 4 by sewing. As a result, the flexible radiation protection body 2, the sheath and the bodies 3 and 4 are integrated. Instead of sewing, the edges of the radiation protection body 2 and the sheet-like bodies 3 and 4 may be integrated by welding or adhesion.

Since radiation enters from the arm hole part of the coat type and apron type radiation protective clothing, the width of the portion covering the chest of the radiation protective clothing 1 and the arm hole portion (side part of the chest) of the radiation protective clothing is widened as shown in FIG. This is very important. Moreover, it is preferable to provide the fixing position of the both ends of the radiation protective clothing 1 in the vicinity of the chest side part which avoids the radiation which invades from the center part of the chest or the armhole part in order to facilitate the attaching / detaching work. When provided on the side of the chest, both ends of the radiation protective clothing 1 can be overlapped and fixed in a doubled manner to reduce radiation intrusion from both ends. The radiation protective clothing 1 of the present invention may have a substantially rectangular shape with a wide portion covering the chest and the side of the chest and a narrow back portion, or a wide rectangular shape with the entire circumference being wide.

A rubber-like body 6 such as a rubber string is attached to the upper and lower ends or the end of the radiation protective clothing 1. As shown in FIG. 4, the upper and lower ends of the radiation protective clothing 1 can be brought into close contact with the chest of the wearer by the rubber-like body 6. Further, fasteners 7 are attached to both ends of the radiation protective clothing 1 in order to wrap and fix the substantially rectangular radiation protective clothing 1 around the chest of the wearer. The fastener 7 is preferably a hook-and-loop fastener with excellent handleability.

FIG. 4 shows a state where the mannequin M is worn with the radiation protective clothing 1 of the present invention. When a woman wears, the protective clothing may be pulled in a convex shape due to the swelling of the breast, and a gap may be formed on the upper or lower end of the protective clothing 1, but the chest and both sides of the chest are wide as shown in FIG. As a result, the bulge of the breast is covered with a margin, so that no gap is formed on the upper or lower end of the protective clothing 1. Further, if the radiation protective clothing 1 is worn for a long time, the radiation protective clothing may be displaced, but the shift can be prevented by attaching a shoulder strap (not shown).

The radiation protective clothing 1 is required to have high airtightness in order to maintain its function, but there is a problem of a large amount of sweating caused by the wearer and stuffiness resulting therefrom. Such a problem can be alleviated by using a fiber cloth for the sheet-like body 4 that covers the back surface of the radiation protection body 2, but the sheet-like body 4 is laminated with a breathable mesh or a three-dimensional solid knitted fabric (see Japanese Patent No. 3943011). Then, stuffiness can be reduced further.

Radiation that enters from the armholes on the left and right sides of the radiation protective clothing if the radiation medical personnel etc. wear the radiation protective clothing (radiation protective bra) of the present invention before wearing the coat type and apron type radiation protective clothing Can be reduced.
For this reason, radiological medical parties and the like can perform medical care and the like without worrying about the onset of breast cancer or the like due to radiation exposure to the mammary gland, and are highly available in the medical field.
