Rescue face mask

Abstract

The invention discloses a rescue face mask and relates to a medical appliance. The rescue face mask consists of a lining gasket fit with the mouth and nose, a cover, an oxygen adaptor with a cap, and an air inlet pipe part, wherein the air inlet pipe part consists of an upper pipe and a lower pipe; a filtering screen is arranged in the upper pipe, and an exhaust hole is arranged in the lower pipe; and a one-way valve comprises one-way valve plates of which part is connected and fixed between the upper and lower pipes and the left part is in a free state. When worn by a patient, the face mask is adhered onto the mouth and nose on faces and fastened by elastic belts; and the face mask can be connected with an oxygen cylinder for allowing the patient to indraft oxygen independently, or connected with a breathing machine for performing manual rescue or used by medical personnel to perform mouth-to-mouth breathing rescue without interaction, and the three kinds of operation can be performed alternatively or synchronously. The rescue face mask can improve rescue efficiency, prevent large-particle materials from entering the mouth of patients, and has the characteristics of reasonable design, use sanitation and convenience, and the like.

Description

Technical field [0001] The invention relates to a medical device, in particular to a rescue mask for breathing. Background technique [0002] For patients with respiratory and cardiovascular diseases, they need to wear an oxygen mask for oxygen inhalation when they are seriously ill. When the critically ill patient has difficulty breathing on its own and stops breathing symptoms, medical personnel must remove the oxygen mask for artificial respiration. In the past, mouth-to-mouth rescue was always used during artificial respiration. At this time, the mask must be removed first. Not only is the operation troublesome and may delay the rescue opportunity, what is more frightening is that the secretions sprayed from the mouth between the two sides contaminate each other and cause cross-infection. The technical solution disclosed in "A breathing mask" with the Chinese Patent Document Publication No. CN201426908Y is: a cover body, a gasket connecting the cover body, a connection pipe c...

Problems solved by technology

But for the rescue of critically ill patients, every second counts. Artificial respiration needs to be connected to a ventilator, and it is difficult to achieve the purpose of rescue immediately. When necessary, medical personnel are still required to provide mouth-to-mouth rescue, but it is easy to cause mutual infection.
