Problems solved by technology

Therefore, if respiratory equipment is used by multiple patients, they run the risk of becoming vectors for the transmission of various viruses and / or bacteria
Furthermore, many of the devices developed by at least some of the inventors of this specification require individual measurements of airflow and / or pressure at each breathing port, but these measurements are difficult using related art single-lumen and / or dual-lumen nasal cannulas, especially It's about nose and mouth measurements

Embodiment Construction

[0019] Certain terms are used in the following description and claims to refer to particular system components. This document does not intend to distinguish between components that differ in name but not function.

[0020] In the following description and claims, the terms "comprising" and "consisting of are used in an open-ended manner and thus should be construed to mean "including, without limitation...". Also, the term "connected" is used to indicate a direct or indirect connection. Thus, if a first device connects to a second device, that connection may be through a direct connection, or through an indirect connection via other devices and connections.

[0021] FIG. 1 illustrates three cannula assemblies 10 including a first nasal cannula assembly 12 , a second nasal cannula assembly 14 and an oral cannula assembly 16 . The first nasal cannula assembly 12 includes a cannula 18 having a nasal interface or tube 20 on the bore or patient end, and a connector 22 on the devi...

Abstract

An improved nasal cannula is provided. Some illustrative embodiments are a cannula comprising a first nasal tube having a device end and an aperture end (wherein the cannula is configured to place the aperture end in fluid communication with the first naris of a patient), a second nasal tubing having a device end and an aperture end (wherein the cannula is configured to place the aperture end of the second nasal tubing in fluid communication with a second naris of the patient), and an oral tubing having a device end and an aperture end, and the oral tubing mechanically coupled to at least one of the first or second nasal tubing (wherein the cannula is configured to place the aperture end of the oral tubing in fluid communication with the mouth of a patient). The first nasal tubing, the second nasal tubing and the oral tubing are fluidly independent between their aperture ends and their device ends.

Description

technical field [0001] Embodiments of the present invention are directed to nasal and oronasal cannulae. Background technique [0002] Related Art Intubation occurs in several ways. A "single lumen" cannula provides a single fluid connection from the patient's nostril to respiratory equipment such as an oxygen concentrator. Each length of tube extending over the patient's ear fluidly joins, such as under the patient's chin or behind the patient's head. Thus, in a single lumen cannula, there is only a single flow path between the patient and the breathing apparatus, despite the fact that the cannula may have two nasal tubes, one for each nostril. A "dual lumen", "bifurcated" or split nasal cannula must have two separate flow paths, one for each nostril of the patient. Much like a single lumen cannula, a dual lumen cannula can have two nasal tubes. In a dual lumen cannula, however, the flow paths to each nostril may be divided by baffles or bifurcations. [0003] Nasal ca...
