Oxygen inhalation mask used in cardio-cerebral medical department

Abstract

Disclosed is an oxygen inhalation mask used in the cardio-cerebral medical department. The space inside a nose and mouth mask body and the space outside the nose and mouth mask body are communicated through a sleeve, an air guiding port is formed in the side wall of the portion, located inside the nose and mouth mask body, of the sleeve, and the air guiding port is communicated with an air inlet pipe through a hose in an airtight mode; a nose plug is connected to the interior of the sleeve in front-back sliding and airtight modes, the nose plug is in the shape of a cylinder with the inner end open and outer end closed, a push rod is fixedly connected to the outer end of the nose plug, a communication port is formed in the side wall of the nose plug, and the communication port passes through the air guiding port during movement; an air exchange port is further formed in the side wall of the portion, behind the air guiding port, of the sleeve, and the air exchange port enables the space inside the nose and mouth mask body and the space outside the nose and mouth mask body to be communicated after the communication port intersects with the air guiding port; the sleeve is in flexible connection with the nose and mouth mask body; the communication port is located at the rear end of the side wall of the nose plug, and the air guiding port is located at the front end of the side wall of the sleeve; the communication port is round, and the air guiding port is a strip-shaped port arranged in the moving direction of the communication port; a stop lever is fixedly connected to the push rod and perpendicular to the push rod, and the length of the stop lever is larger than the distance between the push rod and the inner wall of the sleeve.

Description

technical field [0001] The invention relates to a medical device for oxygen inhalation, in particular to an oxygen inhalation mask for cardio-cerebral medicine. Background technique [0002] In clinical medicine, especially in cardiology and brain medicine, oxygen inhalation tools are often used. The more commonly used are oxygen inhalation masks and oxygen inhalation nasal plugs. Both oxygen inhalation masks and oxygen inhalation nasal plugs can improve the utilization rate of accumulated gas, thereby improving The concentration of inhaled oxygen, for patients with difficulty breathing. The oxygen inhalation mask is placed on the patient's nose and mouth when in use, which can effectively and quickly increase the blood oxygen saturation and improve the patient's hypoxic state. It is mostly suitable for patients with severe illness, coma and postoperative patients. When oxygen is inhaled at a low flow rate, the oxygen inhalation mask can no longer be used, because the patie...

AI Technical Summary

Problems solved by technology

The oxygen inhalation mask is placed on the patient's nose and mouth when in use, which can effectively and quickly increase the blood oxygen saturation and improve the patient's hypoxic state. It is mostly suitable for patients with severe illness, coma and postoperative patients. When inhaling oxygen at a low flow rate, you cannot continue to use the oxygen inhalation mask, because the patient will feel suffocated at this time, so the oxygen inhalation nasal plug should be replaced in time, which undoubtedly causes a waste of medical equipment

Moreover, some patients are in good and bad conditions, and need to replace oxygen inhalation tools many times, which also brings more workload
