Multifunctional protective mask used for otorhinolaryngology head and neck surgery

Abstract

The invention discloses a multifunctional protective mask used for otorhinolaryngology head and neck surgery. The multifunctional protective mask comprises a multifunctional protective mask body; theouter side of the multifunctional protective mask body is movably connected with a protective screen; side frames are symmetrically and fixedly connected with two ends of the protective screen respectively; inner sides of the side frames are rotatably connected with a right glasses leg and a left glasses leg respectively; rotary adjusting buttons are arranged at the joint of the right glasses legand the side frame and the joint of the left glasses leg and the side frame respectively; a gear is arranged in each rotary adjusting button; the outer side of the right glasses leg and the outer sideof the left glasses leg are each fixedly connected with an elastic band; one end of each elastic band is fixedly connected with a connecting buckle; the front end of the right glasses leg and the front end of the left glasses leg are fixedly connected with a left side frame and a right side frame respectively; the inner side of the left side frame is fixedly connected with a left glasses frame; and the interior of the right side frame is fixedly connected with a right glasses frame. The multifunctional protective mask has a simple structure and a novel design, and secretions of the nasal cavity, oral cavity and trachea of a patient can be prevented in the diagnosis and treatment process by installing the transparent protective mask.

Description

technical field [0001] The invention relates to the technical field of protective masks, in particular to a multifunctional protective mask used in otolaryngology head and neck surgery. Background technique [0002] The otolaryngology and related head and neck organs are located deep in the cranium and jaw, and the cavities are narrow and tortuous, making it difficult to observe directly. Otorhinolaryngology head and neck surgeons need special light sources, forehead mirrors and special instruments to diagnose and treat diseases. In clinical work, the Otorhinolaryngology Head and Neck Surgery Diagnosis and Treatment Workbench integrates light sources and commonly used instruments, and doctors need to bring their own forehead mirrors for otolaryngology disease diagnosis. The workbench creates a relatively independent working environment for doctors, but at the same time it also limits the place of diagnosis and treatment. For example, doctors cannot conduct timely diagnosis ...

Problems solved by technology

During diagnosis and treatment, secretions from the patient's nasal cavity, oral cavity and trachea, especially those with epistaxis and tracheotomy, are easily sprayed onto the faces of medical staff, increasing the risk of medical staff infection. Secondly, the existing protective masks have poor air permeability. Good, causing water mist on the protective mask
