Description

  The present invention relates to protective clothing for protecting a worker's body from harmful substances when working with hazardous materials, and in particular, an operator who is shielded from the outside air by the protective clothing is trapped in the protective clothing. The present invention relates to a protective garment that can prevent being affected by heat stroke.

  Traditionally, when handling harmful substances such as harmful chemicals and asbestos, in order to protect the worker's body from harmful substances, it is necessary to wear protective clothing that shields the worker's body from the outside air. Has been done.

  As shown in FIG. 1, these protective clothing bodies 1 are usually made of an airtight fabric that blocks the transmission of harmful substances, and the outerwear and trousers are connected to each other up and down. A separate glove 3 and overshoe 4 are attached to the sleeve part and the tip part of the leg part of the protective clothing main body 2 without any gap.

  In addition, a hood 5 that covers the head is formed integrally with the body 2 of the protective clothing, and the periphery of the opening of the face is in close contact with the face by rubber or the like to prevent harmful substances from entering the protective clothing 1 as much as possible. It has become. When handling highly harmful substances, the face is covered with a mask and breathing is secured through a gas mask.

  As described above, the protective clothing 1 blocks the worker's body and the outside air with the protective clothing 1, and therefore air circulation between the inside of the protective clothing 1 and the outside air is poor. Therefore, when the user wears the protective clothing 1 and works for a long time, heat is trapped in the protective clothing 1 and the heat is not released, so that the worker is likely to suffer from heat stroke.

  As means for lowering human body temperature to prevent heat stroke, for example, one disclosed in Japanese Patent Application Laid-Open No. 2004-76240 is known. This is a cold pack attached to the chest and back of clothes.

  However, in general, in order to prevent heat stroke, it is said that it is good to cool the part where the thick artery passes near the body surface such as the neck, axilla, and crotch, and even if a cold pack is provided on the chest and back It is less effective in preventing heat stroke. Further, by further wearing such clothing on or under the protective clothing 1, there is a risk of further suppressing heat dissipation.

  Moreover, what was shown by Unexamined-Japanese-Patent No. 2002-119530 is known as a thing which cools the location effective for the above-mentioned heat stroke prevention intensively. In this method, cooling pads are arranged in the neck, axilla, crotch, etc., and the cooling liquid is circulated through them. However, if the cooling pad moves during the operation, it feels heavy and the working efficiency is lowered.

Furthermore, Japanese Patent Application Laid-Open No. 2006-57189 discloses a tool for cooling from a person's neck to a shoulder, but it is effective to cool the neck, but it is not preferable to cool the shoulder. Cause. In the structure shown in the above publication, it is difficult to cool only the neck.

  The present invention has been made in view of such circumstances, and the cooling pad is detachably attached to the protective clothing as described above, and the cooling pad comes into contact with the neck and the top of the operator by wearing the protective clothing. The purpose is to lower the body temperature by cooling the neck to prevent heat stroke, and to provide a refreshing feeling by cooling the top of the head.

  Thus, the protective clothing of the present invention is a protective clothing having a hood that covers the head with upper and lower joints, and a cold insulation agent is provided inside the protective clothing main body at a position corresponding to the neck of the wearer and the top of the hood. Or the pocket which accommodates the cooling pad which uses a coolant was formed.

  In order to form the pocket in the present invention, a sheet is brought into contact with the inner surface of the protective clothing main body and the hood, and the pocket is formed by joining a peripheral edge except for one edge of the sheet to the protective clothing main body and the hood. it can.

  As another method, an inverted T-shaped sheet is brought into contact with the inner surface of the position surrounding the wearer's neck in the protective clothing body and the hood and the position from the wearer's back neck to the top of the head, The pocket can also be formed by joining the periphery of the sheet to the protective clothing body and the hood except for the upper edge of the seat surrounding the neck and the leading edge of the portion from the back neck to the top of the head.

  In the present invention, the sheet is suitably made of a woven fabric or a non-woven fabric. Moreover, it is preferable to join the said sheet | seat with the said protective clothing main body or hood by a sewing, adhesion | attachment, or heat sealing | fusion.

  According to the present invention, when the cooling pad is accommodated in the pocket of the protective clothing and the protective clothing is worn in this state, the cooling pad naturally comes into contact with the neck and the top of the wearer. By cooling the neck, it cools the blood flow toward the brain, preventing an excessive increase in the temperature of the brain, and reducing the temperature of the whole body by circulating the blood flow, thereby preventing heat stroke. . Further, by lowering the temperature of the brain and cooling the top of the head, the wearer can feel refreshed and improve work efficiency.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 shows a state in which the chest fastener 6 of the protective clothing main body 2 is opened and the facial opening of the hood 5 covering the head is greatly expanded in the protective clothing of the present invention.

  Thus, a neck pocket 7 is formed inside a portion where the hood 5 is attached to the protective clothing main body 2, that is, a position surrounding the neck of the wearer. The neck pocket 7 is provided with a horizontally long sheet 8 at the boundary between the protective clothing main body 2 and the hood 5, and the protective clothing main body 2 is attached to the peripheral edge portion and the central portion 9 excluding the upper portion of the seat 8. The cooling pad 10 is accommodated in the neck pocket 7 from the upper opening.

  A head pocket 11 is also formed inside the position corresponding to the top of the hood 5. The head pocket 11 is also composed of a sheet 8 that is long in the front and rear, the peripheral edge portion except the rear portion of the seat 8 is joined to the hood 5 at the joint portion 9, and the cooling pad 10 is accommodated in the head pocket 11 from the rear opening portion. It is like that.

  FIG. 3 shows another embodiment of the present invention, in which an inverted T-shaped pocket 12 is formed from the position surrounding the neck of the wearer to the top of the head. That is, an inverted T-shaped sheet 8 is disposed on the inner surface of the position surrounding the wearer's neck in the protective clothing main body 2 and the position from the rear neck to the top of the wearer. The peripheral edge of the seat 8 is joined to the protective clothing body 2 and the hood 5 except for the upper edge of the surrounding part and the leading edge of the part from the back neck to the top of the head, and the upper edge and the back neck of the part surrounding the neck. The cooling pad 10 is accommodated in the inverted T-shaped pocket 12 from the leading edge of the portion from the top to the top of the head.

  As the sheet 8 constituting the pockets 7, 11 and 12, it is appropriate to use a woven fabric or a non-woven fabric. Further, as means for joining the sheet 8 to the protective clothing main body 2 and the hood 5, it is possible to use means such as stitching, adhesion or heat fusion. In the case of suturing, a needle hole is generated in the joint 9, and it is preferable to use adhesion or heat fusion.

  The cooling pad 10 accommodated in the pockets 7, 11 and 12 is one in which a cooling agent or a coolant is accommodated in a flexible airtight bag. The cold-retaining agent is a water-soluble polymer gel having a large heat capacity, which is cooled in a refrigerator and stored in a pocket. The coolant is cooled by an endothermic reaction or negative heat of dissolution, and the drug is mixed or dissolved immediately before use.

  According to the present invention, if the cooled cooling pad 10 is accommodated in the pockets 7, 11, 12 of the protective clothing 1, the protective clothing 1 is worn in this state, the fastener 6 is closed, and the head is covered with the hood 5, As shown in FIG. 1, the cooling pad 10 is naturally located on the neck and top of the wearer.

  Accordingly, if the work is performed as it is, the neck of the worker is cooled by the cooling pad 10 and heat stroke can be prevented, and the top of the head is cooled, so that the worker feels refreshed and the working efficiency is improved. .

  After the work for a predetermined time is completed, the protective clothing 1 is taken off, the cooling pad 10 is removed, and if the cooling pad 10 uses a cooling agent, it is cooled again and reused. Further, the cooling pad 10 using the coolant is usually discarded. Moreover, the protective clothing 1 from which the cooling pad 10 has been removed can be discarded according to its use, or, if possible, the cooling pad 10 that has been cooled again can be accommodated and reused.
