Description

Oxygen inhalation mask for reducing infectious disease spreading

[ technical field ] A method for producing a semiconductor device

The utility model relates to the technical field of medical appliances, in particular to an oxygen inhalation mask for reducing infectious disease spread.

[ background of the invention ]

The oxygen mask is a breathing mask for continuously supplying oxygen to a patient, can provide high-concentration oxygen and high-pressure support for the patient so as to improve the oxygenation deficiency of the patient and reduce the work of breathing of the patient, and is an important appliance for saving the life of a critical patient. The oxygen inhalation mask used in the existing hospital basically has the following problems:

(1) the airtightness is poor. Patients who have infectious diseases and can be infected by sputum, droplets and aerosol, such as new crown patients and respiratory tract infection patients with various uncertain pathogens, exhale the sputum, droplets and aerosol with the pathogens in the breathing process to spread everywhere, inevitably cause air pollution in wards, cause virus diffusion, and cause cross infection among patients and infection of medical care personnel;

(2) is inconvenient for sputum suction operation. The patient often needs to perform sputum suction operation during oxygen inhalation, at the moment, the oxygen inhalation mask needs to be taken off, and then the sputum suction is performed on the oral cavity of the patient, so that the sputum suction is performed in such a way, the oxygen supply interruption of the patient is easily caused, and the condition of the patient can be aggravated; in addition, the sputum aspiration process can generate a large amount of spray and aerosol, which is an important time for spreading the infectious agents.

Some studies have also proposed some solutions to the above problems, but none are comprehensive. For example, chinese utility model patent CN2627861Y is an on-demand oxygen inhalation and toxin expelling mask, which improves the air tightness of the mask by arranging a sealing ring at the edge of the mask, and enables the gas exhaled by the patient to be pumped away by a suction pump by combining a sensor, a three-way pipe and a steering control valve, thereby achieving the effect of preventing the gas exhaled by the patient from diffusing around to cause virus propagation, but the sealing effect is still not good and the sputum aspiration operation cannot be performed on the patient while wearing the mask; the chinese utility model patent CN209378249U discloses an oxygen mask convenient for sputum aspiration operation, which can aspirate oxygen while aspirating oxygen, but cannot control the diffusion of exhaled air of patients, and is not suitable for patients with infectious diseases.
