Background

The full-face mask is widely applied to the field of emergency rescue. The protective device is a protective device with a moderate protective grade, and the protective grade of the protective device is about 100 times (the national standard stipulates that the protective factor APF is 100), is higher than negative pressure respiratory protective devices (APF is 10) such as a mask, a half mask and the like, and is also higher than positive pressure respiratory protective products represented by an electric air supply respiratory system (the positive pressure protective grade is different from 25-2000 times). Therefore, the overall tool is a breathing protection device which is commonly used. At present, in the field of emergency rescue, the comprehensive tool is mainly used for: biological emergency, biological counterterrorism, epidemic investigation, patient transportation, corpse treatment, chemical emergency (such as sarin, mustard gas and the like) or chemical leakage ready treatment, and some post-disaster investigation (such as earthquake and the like), in the above working links, the breathing of the wearer can be comprehensively and effectively protected.

When activities such as emergency rescue are carried out, emergency team members wear heavy and complex equipment to protect themselves. In addition to this, various tools need to be carried. If the light on site is dim or no light exists, the user needs to carry the light source to enter the site to complete the task. This time the handheld light source becomes a burden. Because they need to carry other materials, such as: sampling box, notebook, recording pen, or intercom.

In addition, if the wounded person is to be rescued or suspected cases are isolated, controlled, etc., it is less possible to operate with one hand, with illumination provided by a hand-held light source (e.g., flashlight).

There is a need for improvement.
