Definitions

  • the present invention relates to a protective garment.
  • a protective garment has various kinds of forms and functions depending on its purpose and usage. Especially, to prevent dirt, chemicals, viruses, bacteria, and the like from adhering to a body, there has been a protective garment of a coverall type (overall type) in which an upper part of the garment that includes a body portion, a hood portion, and sleeve portions is integrally formed with a lower part of the garment.
  • coverall type overall type
  • a wearer of protective garment needs not only to follow a proper method of donning to reduce a risk of contamination, but also to prevent contamination (secondary contamination) when doffing the protective garment. Since a mistake in a procedure and a method for doffing the protective garment possibly causes the secondary contamination, ease in doffing the garment is very important for the prevention of the secondary contamination. Further, for example, when it takes a time for a person engaged in medical treatment dealing with an emergency patient to doff the garment in doffing protective garment after dealing with an emergency patient suspected of having an infectious disease in a state of wearing the protective garment, a response to the next patient transported emergently delays.
  • Patent Literature 1 JP 2005-23460 A
  • the protective garment of Patent Literature 1 is a coverall type protective garment that includes an open/close portion for doffing it. According to the findings by the present inventors, when doffing the protective garment disclosed in Patent Literature 1, the open/close portion is opened and its hood is doffed at first. Subsequently, after shoulders are removed from an opening portion of the protective garment formed by opening the open/close portion, arms are removed, thereby doffing its upper part of the garment. Then, its lower part of the garment is doffed. While the protective garment of Patent Literature 1 includes the open/close portion for donning and doffing it in a front body, the movement of the upper part of the garment is restricted by the lower part of the garment because of the coverall type. Therefore, there has been a problem in that the removal of the shoulders is difficult in doffing the garment, and consequently, doffing the garment is difficult.
  • the present invention has an object to provide protective garment that ensures facilitated doffing.
  • a protective garment comprises: an upper part of the garment that includes a body portion, a pair of sleeve portions, and a hood portion; a lower part of the garment connected to the upper part of the garment; and an open/close portion formed in a front body portion of the body portion for donning and doffing of the protective garment.
  • a stretchable portion is formed in a boundary between a back body portion of the body portion and the hood portion.
  • the protective garment is a coverall type protective garment.
  • This protective garment is doffed, shoulders, arms, and legs are removed from an opening portion (opened portion) of the protective garment formed by opening the open/close portion.
  • the open/close portion is formed in the front body portion of the body portion, a wearer of the protective garment easily operates the open/close portion.
  • the stretchable portion is formed in the boundary between the back body portion and the hood portion, the opening portion can be expanded by stretching the stretchable portion in the removal of the shoulders from the opening portion. Consequently, the shoulders are easily removed from the opening portion. Accordingly, the protective garment facilitates doffing.
  • Fabrics of the upper part of the garment and the lower part of the garment may have a viral barrier property of class 4 or higher.
  • the protective garment using such a fabric is effective for the infection control.
  • the shoulders of the wearer are easily removed by stretching the stretchable portion (boundary) in doffing the garment.
  • the stretchable portion may be configured to be stretched to have a distance between shoulder portions or more assuming that a distance between a shoulder portion in a left side and a shoulder portion in a right side of the upper part of the garment is defined as the distance between the shoulder portions in a state where the front body portion and the back body portion are stacked and a state where the stretchable portion is not stretched.
  • the stretchable portion can be stretched and expanded to the shoulder width or more of the wearer by stretching the stretchable portion (boundary) in doffing the garment, doffing the garment is further easier.
  • the stretchable portion may be configured to be stretched to have a shoulder width or more of a wearer in a state where the wearer having the shoulder width of 406 mm wears the protective garment. Also in this case, since the wearer can stretch the stretchable portion (boundary) in doffing the garment and the stretchable portion is stretched and expanded to the shoulder width or more of the wearer, doffing the garment is further easier.
  • the shoulder width of the wearer means a direct distance between right and left acromial points.
  • At least a part of the hood portion and at least a part of the back body portion, disposed across the boundary, and the boundary may be formed of one continuous fabric. In this case, since there is no joint line in the boundary, the protectiveness can be ensured more.
