Carbon dioxide feedback regulation system for tracheal catheter hood

Abstract

The invention relates to medical equipment for clinically correcting hyoxemia of common patients or hypocapnia caused by hyperventilation and in particular relates to a carbon dioxide feedback regulation system for a tracheal catheter hood. The system is characterized by at least comprising a sealed container (1), wherein the sealed container (1) at least comprises three nozzles, the first nozzle (2) is connected with a carbon dioxide collection tube (3), the second nozzle (4) is connected with a carbon dioxide gas source (5), and the third nozzle (6) is connected with a check valve (7); and a carbon dioxide sensor (8) extends into the sealed container (1), and is used for detecting the concentration of carbon dioxide in the sealed container (1). The system has the advantages that the carbon dioxide collection tube extracted from a hypocapnia patient is communicated with the sealed container, and the sealed container can be used for reasonably controlling the concentration of carbon dioxide through a controller, so that the port concentration of the carbon dioxide collection tube cannot change greatly, and the safety of the patient in treatment is ensured.

Description

Technical field [0001] The invention relates to a medical device for correcting hypoxemia in ordinary patients or hypocapnia caused by hyperventilation in clinic, in particular to a carbon dioxide negative feedback adjustment system for tracheal tube masks. Background technique [0002] In clinical correction of hypoxemia in ordinary patients or hypocapnia caused by hyperventilation, a mask is used to inhale oxygen, but for patients with tracheal intubation or tracheotomy, the mask cannot be used. Paper is usually rolled into a triangular cone or The box is buckled above the intubation tube to improve the symptoms of hypoxia or increase the partial pressure of carbon dioxide. This method is convenient to obtain materials, but it is unsightly and irregular. It is often replaced by frequent replacement of the paper due to the wetness and contamination of the patient's sputum, which increases the workload. Summary of the invention [0003] The purpose of the present invention is to p...

[0002] In clinical practice, when correcting hypoxemia in ordinary patients or hypocapnia caused by hyperventilation, oxygen masks are used to inhale oxygen, but for patients with tracheal intubation or tracheotomy, masks cannot be used, and paper is often rolled into a triangular cone or The box is buckled above the intubation tube to improve the symptoms of hypoxia or increase the partial pressure of carbon dioxide. This method is convenient for obtaining materials, but it is unsightly and irregular. The paper is often wet and polluted by the patient's sputum. Frequent replacement increases the workload.
