Description

Replaceable single-tube double-lumen or single-lumen oxygen therapy nasopharyngeal airway

Technical Field

The utility model relates to a replaceable single-tube double-cavity or single-cavity oxygen therapy nasopharyngeal airway, belonging to the technical field of medical equipment.

Background technique

For many years, nasopharyngeal airways have been widely used in anesthetized, obese or comatose patients. They not only solve the upper airway obstruction caused by tongue root falling back due to the relaxation of the upper airway floor and pharyngeal muscles caused by the effects of anesthetic drugs, coma or obesity, but also can quickly relieve or alleviate the patient's upper airway ventilation or obstruction, achieving the purpose of upper airway patency.

After several improvements, the nasopharyngeal airway on the market now has devices that can simultaneously connect to an oxygen tube to deliver oxygen or monitor end-tidal carbon dioxide. However, for patients who need double-lumen nasal cannula oxygen inhalation, there is currently no device that effectively adapts to the nasopharyngeal airway to relieve and eliminate upper respiratory tract obstruction, facilitate the removal of sputum, and allow both nasal cavities to inhale oxygen at the same time.

For some patients with upper airway obstruction or respiratory diseases, double-lumen nasal cannula oxygen inhalation may be required to ensure that both nasal cavities can inhale oxygen. However, the traditional nasopharyngeal airway design may not be able to meet these needs at the same time. This leads to some problems: (1) Some patients may experience upper airway obstruction, resulting in difficulty breathing and discomfort. The traditional nasopharyngeal airway cannot effectively relieve and relieve upper airway obstruction, limiting the patient's ventilation function; (2) The traditional nasopharyngeal airway may only cover one side of the nasal cavity and cannot meet the needs of bilateral nasal oxygen inhalation at the same time; this may lead to uneven oxygen distribution and affect the effect of oxygen therapy; (3) For nasopharyngeal airway patients who need oxygen therapy, simultaneous suction is an important treatment measure; however, traditional devices may not be convenient for simultaneous suction, which can easily cause sputum accumulation and affect the patient's breathing and recovery.

Utility Model Content

The technical problem to be solved by the utility model is to improve the existing nasopharyngeal airway which cannot effectively alleviate and relieve upper respiratory tract obstruction and simultaneously meet the needs of bilateral nasal oxygen inhalation and is inconvenient to perform sputum suction at the same time.

In order to solve the above technical problems, the utility model provides an effectively adapted nasopharyngeal airway device, which can not only relieve and eliminate upper respiratory tract obstruction, but also enable both nasal cavities to inhale oxygen at the same time and facilitate the removal of sputum through the natural cavity; therefore, the utility model achieves this purpose by improving and adding a replaceable single/double-cavity adapter to provide individualized treatment.

In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

A replaceable single-tube double-lumen or single-lumen oxygen therapy nasopharyngeal airway, comprising a nasopharyngeal airway, a connector, a replaceable single-tube adapter, an oxygen delivery connecting tube, and an end-tidal carbon dioxide monitoring catheter; wherein the replaceable single-tube adapter is a single-tube double-lumen adapter or a single-tube single-lumen adapter, the lower part of the nasopharyngeal airway is detachably connected to the replaceable single-tube adapter via the connector, the bottom of the replaceable single-tube adapter is connected to the oxygen delivery connecting tube, the end-tidal carbon dioxide monitoring catheter passes through the replaceable single-tube adapter and is partially placed in the nasopharyngeal airway.

Furthermore, the single-tube dual-cavity adapter is provided with a right nasal oxygen delivery tube, a left nasal oxygen delivery tube, and a total oxygen delivery single tube, wherein the right nasal oxygen delivery tube and the left nasal oxygen delivery tube form a U-shaped tube connection, and respectively match the right nasal cavity and the left nasal cavity of the patient, and the total oxygen delivery single tube is located at the bottom of the U-shaped tube and is connected to the oxygen delivery connecting tube.

Furthermore, a single-tube single-lumen oxygen delivery tube is provided on the side of the single-tube single-lumen adapter, and the single-tube single-lumen oxygen delivery tube is connected to the oxygen delivery connecting tube.

Furthermore, a secretion suction port is provided at the bottom of the replaceable single-tube adapter.

Furthermore, the secretion suction port is provided with a suction port blocking device which can be mounted on or connected to a replaceable single-tube adapter.

Preferably, the bottom of the end-tidal carbon dioxide monitoring catheter is connected to the end-tidal carbon dioxide monitoring probe.

The effectively adapted nasopharyngeal airway device provided by the utility model has the following advantages:

1. For obese patients, patients who are not fully awake or comatose due to anesthesia, the placement of a nasopharyngeal airway can relieve and eliminate upper respiratory tract obstruction, improve oxygenation, and facilitate the removal of throat secretions. However, after the placement of the nasopharyngeal airway, ordinary nasal catheters cannot meet the requirements of oxygen inhalation in both nasal cavities at the same time. Therefore, the adapter is used to meet the requirements of the use of the nasopharyngeal airway, while both nasal cavities can inhale oxygen, and the throat secretions are removed from the special channel without deoxygenation, which is conducive to the removal of secretions and can also monitor the concentration of carbon dioxide in the exhaled air.

2. It is easy to implement in clinical practice, with simple operation and cheap consumables. By replacing the adapter, it can match the patient's need for double-chamber oxygen inhalation, while retaining the nasopharyngeal airway itself to relieve upper respiratory tract obstruction. The dedicated suction tube channel is more convenient for clinical secretion removal, and can also monitor the exhaled carbon dioxide concentration, improve patient oxygenation and provide monitoring value, with strong clinical practicality.
