Shoulder-carried reusable inhaled air filtering and exhaled air sterilizing device for infected patient

Abstract

The invention relates to a shoulder-carried reusable inhaled gas filtering and exhaled gas sterilizing device for an infected patient, belongs to the technical field of medical instruments, and aims to solve the problem that viruses in exhaled gas of a patient infected with respiratory system infectious viruses are effectively killed to block a propagation path of the respiratory system infectiousviruses while the viruses in the inhaled gas of the patient are filtered. The device specifically comprises a mask, an airway catheter and a shoulder carrying body, the mask is formed by silica gel according to the face shape and used for covering the mouth and nose of a patient, the airway catheter is used for exhausting exhaled air to the shoulder carrying body, the shoulder carrying body is used for killing bacteria and viruses in the exhaled air, and the shoulder carrying body is in a micro-arc shape matched with the front of the shoulder, and sequentially comprises an upper air storage chamber, a disinfection box, a filter box, a lower air storage chamber and an air outlet filter port from top to bottom, and the air outlet filter port is provided with an outward one-way soft rubber sheet expiration valve. The device can effectively kill viruses, prevent the viruses from being inhaled into the lung when the patient wears the mask, prevent the patient from worsening the illness state and promote healing.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a shoulder-carrying multiple-use inhalation gas filter and exhalation gas sterilizer suitable for infected patients. Background technique [0002] In this and previous efforts to prevent and combat respiratory infectious diseases, such as novel coronavirus (2019-nCoV), the main measures taken are: [0003] ⑴Isolation: Once the epidemic is discovered, quickly adopt home, distance between people, suspend work and production, prohibit travel, and even close the city and the country, so as to block the transmission of the virus, but the economic loss caused is huge. [0004] ⑵Environmental disinfection: Use disinfectant to kill the virus attached to objects and air by spraying disinfectant on living rooms, restaurants, places and streets to kill the source of infection, but the space for environmental disinfection is limited, and its effect is not thorough.

AI Technical Summary

Problems solved by technology

Specifically, it is used to solve: 1) the problem that traditional masks only block the transmission of viruses but do not kill the viruses that cause infectious diseases; 2) a large number of viruses exhaled by infected patients are blocked on the inside of the mask and become a culture medium for viruses and aggravate the problem; 3) the problem of huge resource consumption
