Respiratory system diseases are common diseases and frequently encountered diseases, main pathological changes are in trachea, bronchus, lung and chest cavity, cough, chest pain and respiration of patients with light pathological changes are affected, patients with severe pathological changes are difficult to breathe and lack of oxygen, even patients with respiratory failure die, and the death rate of the respiratory system is very high in cities and rural areas;
many respiratory diseases are transmitted from person to person through respiratory tract, air, saliva and the like, and in clinic, medical staff treat patients face to face, so that the medical staff are in a polluted environment, and especially in the period of high incidence of infectious diseases such as avian influenza, SARS, pneumonia and the like, the protection of the medical staff is very necessary;
most of the existing protective devices for respiratory diseases with infectious diseases in the respiratory system in the department of respiration are used for placing patients in an isolation ward or uniformly placing the patients in a negative pressure ward, and at the moment, the patients do not have any protective device, and only by ventilation of the negative pressure ward, the mutual infection among the patients is difficult to avoid, and the safety of medical care personnel in the negative pressure ward cannot be ensured;
when a patient needs to be isolated, in the prior art, most patients are provided with masks, then medical staff quickly push sickbeds to corresponding wards, or the medical staff do protection work and then transfer the patient to an isolation cabin, and when the patient is transferred to a designated ward, the patient is transferred to the sickbed, so that the operation is carried out, the patient is likely to pollute the passageway environment in the transfer process, the infection of other people is caused, and the transfer work of the patient is very complicated and laborious;
when the treatment of the infectious patient is finished, the sick bed in which the patient stays is generally required to be disinfected comprehensively, most of the existing sick bed disinfection is realized by manually spraying disinfectant by medical care personnel and then wiping the sick bed with rags for disinfection, so that the disinfection is not complete, the possibility of infection of the next hospitalized patient is caused, and the workload of the medical care personnel is increased;
in summary, the protection device for infectious patients in the prior art has the problems that when the patients are in hospital, the patients may be mutually cross-infected, when doctors are treating in a negative pressure ward, the doctors may be infected, when the patients are transferred, time and labor are wasted, risks of polluting passageway air may exist in the transportation process, and the hospital bed is not completely sterilized after the patients walk;
the present invention therefore provides a respiratory disease protection device to address this problem.
