Description

Technical Field

[0001] The utility model relates to the field of medical diagnosis, in particular to a carbon dioxide collection nasal oxygen tube. Background Art

[0002] Oxygen inhalation is a very important medical technology and is widely used in hospitals. By giving oxygen, the arterial oxygen partial pressure (PaO2) and arterial oxygen saturation (SaO2) can be increased, and the arterial oxygen content (CaO2) can be increased to correct the hypoxic state caused by various reasons, promote tissue metabolism, and maintain the body's vital activities. The most common way of oxygen inhalation is for the patient to retain self-respiration and use a nasal oxygen cannula to inhale oxygen through the nostrils. When used, the patient's inhaled oxygen concentration is increased to meet the oxygen supply demand. At present, monitoring the oxygen saturation of oxygen-inhaling patients can only make basic judgments on the oxygen content in the blood, and there is a lack of effective means to monitor the carbon dioxide content in the patient's blood. The existing technology is to monitor the carbon dioxide partial pressure in the patient's exhaled gas.

[0003] When inhaling oxygen, carbon dioxide partial pressure monitoring can make important judgments about the patient's respiratory status, such as: it can detect abnormalities in the patient's respiratory ventilation in advance. During overventilation, blood carbon dioxide is discharged from the lungs and the carbon dioxide partial pressure decreases; during underventilation, blood carbon dioxide is insufficiently discharged from the lungs and the carbon dioxide partial pressure increases; it can detect pulmonary embolism in patients at the first time; it can detect the occurrence of respiratory depression in patients at the first time. During respiratory depression, the patient's respiratory rate significantly decreases, and the carbon dioxide partial pressure waveform can be used to analyze changes in the patient's respiratory rhythm at the first time; at the same time, the patient's exhaled carbon dioxide partial pressure waveform can be used to accurately analyze the patient's respiratory phase and detect various respiratory abnormalities or lung diseases in the patient, such as COPD, restrictive ventilation disorders, etc.

[0004] Clinically, there is a need for an effective method or device that can detect the patient's respiratory status while inhaling oxygen. Utility Model Content

The utility model provides a carbon dioxide collection nasal oxygen cannula, comprising a nasal oxygen cannula, an input and output pipe and a mask; the input and output pipes comprise an oxygen supply pipe for conveying oxygen and an output pipe for collecting carbon dioxide, and the oxygen supply pipe and the output pipe are both independent and isolated; the nasal oxygen cannula comprises a nasal oxygen cannula connected to the oxygen supply pipe for conveying oxygen to the nasal cavity or the periphery of the oral cavity, and a collection pipe connected to the output pipe and inserted into the nasal cavity for collecting exhaled carbon dioxide; the outlet of the nasal oxygen cannula is located on the nasal oxygen cannula.

[0006] In addition, the carbon dioxide collection nasal oxygen tube disclosed in the utility model also has the following additional technical features:

[0007] Furthermore, the carbon dioxide collection nasal oxygen tube also includes a mask for increasing the amount of carbon dioxide collected, the mask having a mask chamber covering around the oral cavity or the nasal cavity, and the mask chamber having a channel communicating with the output pipe.

[0008] Furthermore, the oxygen delivery pipeline and the output pipeline are isolated from each other by a partition to form independent pipelines that are not connected.

[0009] Furthermore, the nasal oxygen tube is located at the root of the nasal oxygen tube.
