Oxygen supply hood

Abstract

The invention discloses an oxygen supply hood. The oxygen supply hood comprises a housing, an oxygen joint and a gas outlet, wherein the housing is used for sleeving the head of a patient, and a support ring is fixedly arranged at the lower end of the housing, and fixedly sleeves the periphery of an elastic ring, and the inner diameter of the support ring is adjustable; an inner ring of the elastic ring is used for contacting with the neck of the patient, and the elastic ring is tightly attached to the neck of the patient; the oxygen joint and the gas outlet are both arranged on the housing and communicate with the outside by an inner cavity of the housing; the oxygen joint is used for being connected with an oxygen supply device, and oxygen is introduced into the housing by the oxygen supply device; a virus filter is mounted at the gas outlet, and is used for filtering viruses in gas discharged through the gas outlet. The oxygen supply hood has good sealing performance and high comfort, and can effectively prevent spread of infectious diseases.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an oxygen supply hood. Background technique [0002] Oxygen inhalation is a relatively common treatment for hospitalized patients, especially for patients with poor lung function. Oxygen inhalation can greatly improve the blood oxygen concentration of patients. At present, there are two main methods for inhaling oxygen clinically. One is to inhale oxygen through an oxygen inhalation tube. However, wearing an oxygen inhalation tube for a long time can cause nasal discomfort and even nasal dermatitis. In addition, if the oxygen flow rate is too large, The airflow entering the nostrils can also easily cause discomfort; the other is to give oxygen through an oxygen inhalation mask, but the traditional oxygen inhalation mask has poor sealing. [0003] The transmission of respiratory infectious diseases is often spread through droplets. When treating patients with respiratory ...

AI Technical Summary

Problems solved by technology

At present, there are two main methods for inhaling oxygen clinically. One is to inhale oxygen through an oxygen inhalation tube. However, wearing an oxygen inhalation tube for a long time can cause nasal discomfort and even nasal dermatitis. In addition, if the oxygen flow rate is too large, The airflow entering the nostrils can also easily cause discomfort; the other is to give oxygen through an oxygen inhalation mask, but the traditional oxygen inhalation mask does not have a good seal

[0003] The transmission of respiratory infectious diseases is often spread through droplets. When treating patients with respiratory infectious diseases, precautions should be taken at all times. Oxygen inhalation methods such as oxygen inhalation tubes and traditional oxygen masks are not conducive to the health of patients with respiratory infectious diseases. It can easily lead to the spread of the virus, which not only endangers other patients, but also increases the risk of infection for medical staff

[0004] Moreover, the existing oxygen inhalation hoods have a single function, most of which are just an ordinary shell, which cannot effectively monitor and control the concentration of oxygen and carbon dioxide, have no protective effect on patients, and are difficult to be promoted clinically.
