Medical protective isolation device for major respiratory infectious diseases

Abstract

The invention discloses a medical protective isolation device for major respiratory infectious diseases. The medical protective isolation device comprises an isolation cover, a hanging bracket and anexhaust system, wherein the isolation cover is composed of an inflatable seat, a lower inflatable seat, inflatable columns and a plastic film; the upper inflatable seat is connected with the lower inflatable seat through the inflatable columns; the plastic film is arranged on the inflatable columns; air inlets are formed in the isolation cover and are provided with a first filter layer; an upper film cover is fixed on the inner inflatable seat; an air outlet is formed in the upper film cover and is provided with a second filter layer; a retractable lower film is fixed on the lower inflatable seat; and a round hole is formed in the lower film. A rope penetrates through the round hole; when sputum is collected from a patient, the patient is sleeved with the isolation cover and fastens the rope; and a miniature sampling chamber in a negative pressure state is formed in the isolation cover, so that a virus propagation path is effectively cut off in a collection process, and medical personnel are protected from being infected by viruses.

Description

technical field [0001] The invention relates to the field of medical protection, more specifically, to a medical protection and isolation device for major respiratory infectious diseases. Background technique [0002] At present, in the medical and health industry, when doctors treat patients with infectious diseases, especially those with droplet, contact, and aerosol transmission routes like new coronary pneumonia, they often need to perform some high-risk diagnosis and treatment operations, such as Nebulization inhalation treatment, induced sputum operation, collection of sputum specimens, etc., in some areas with limited medical conditions and supplies, do not have the necessary conditions to operate under negative pressure. It is also easy to float in the air in the form of droplets or aerosols and deposit on the surface of objects. The infectious droplets or aerosols floating in the air will directly contact the medical staff, which can easily cause cross-infection of ...

[0002] At present, in the medical and health industry, when doctors treat patients with infectious diseases, especially those with droplet, contact, and aerosol transmission routes like new coronary pneumonia, they often need to perform some high-risk diagnosis and treatment operations, such as Nebulization inhalation treatment, induced sputum operation, collection of sputum specimens, etc., in some areas with limited medical conditions and supplies, do not have the necessary conditions to operate under negative pressure. It is also easy to float in the air in the form of droplets or aerosols and deposit on the surface of objects. The infectious droplets or aerosols floating in the air will directly contact the medical staff, which can easily cause cross-infection of the medical staff; The large-scale outbreak of novel coronavirus pneumonia in early 2020 has a long incubation period. Some patients have no obvious early symptoms and are highly contagious, leading to a sharp increase in the number of infections in a short period of time. Medical staff often treat patients with new coronary pneumonia in the process of It is necessary to carry out a series of operations such as collecting the patient's sputum for testing, which is necessary for such diagnosis, treatment and condition monitoring measures for patients with indications. However, in a general ward without negative pressure, even if the medical staff wear a Protective devices such as masks and isolation suits are also difficult to prevent medical staff from being exposed to harmful droplets when collecting sputum from patients, resulting in cross-infection between medical staff and patients. Medical staff are also indirectly infected with new coronary pneumonia, weakening the cause Some medical staff have increased the workload of existing medical staff
