Defogging mask for field operation medical treatment

Abstract

The invention relates to the technical field of respiratory protection devices, and discloses a defogging mask for field operation medical treatment. The defogging mask comprises a main body, a mask body is arranged on one side of the main body, and damping springs are arranged on the left side and the right side of the upper portion of the top of the left side of the mask body. According to the defogging mask for field operation medical treatment, through the combined action of a fixing plate, an extension spring, an arc-shaped scraping plate, a traction rod, a fixing sleeve and a pull ring in a scraping mechanism, the fixing plate plays a role in fixing, the pull ring is pulled downwards to drive the traction rod to move downwards, therefore the arc-shaped scraping plate is pulled to do up-down stretching movement on the inner wall of the mask body, the extension spring can move along with the arc-shaped scraping plate, the fixing sleeve can fix the rod body of the traction rod, the pull ring is loosened after the rod body of the traction rod is pulled to the bottom, the extension spring can automatically pull the arc-shaped scraping plate back to the original position, and therefore when fog exists inside the mask body, the effect that fog can be rapidly removed without disassembling the mask can be achieved.

Description

technical field [0001] The invention relates to the technical field of respiratory protection devices, in particular to a defogging mask for field medical treatment. Background technique [0002] With the wide application of new technologies and new technologies in the respiratory protection industry, more and more auxiliary functions have been derived from the full-face masks with respiratory protection functions, so that the respiratory masks can meet the basic needs while increasing the wearing comfort and practicality. At present, in the field of field medical equipment, in order to prevent respiratory infection and safety and health problems between patients and medical staff, medical staff are required to wear masks at work. In the actual use of existing masks, due to the existence of temperature differences between the inside and outside of the mask, And under the breathing action of the user, it is easy to cause fog to form on the surface of the mask screen. If the ...
