Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a double-tube nasal oxygen tube structure. Background Art

[0002] Oxygen is indispensable to the human body at all times. In severe cases, such as respiratory arrest, mouth-to-mouth breathing is used for cardiopulmonary resuscitation to assist breathing. When the human body is hypoxic due to various reasons, oxygen inhalation is used to help the human body obtain oxygen and relieve breathing difficulties. The purity of medical oxygen is above 98%, and pure oxygen is compressed in special containers. When supplying oxygen to patients with severe hypoxia, 5% carbon dioxide gas is often mixed into pure oxygen to maintain the excitement of the respiratory center. Carbon dioxide is the most important physiological chemical factor in regulating respiratory movements. Carbon dioxide stimulates respiratory movements through two pathways. One is to stimulate central chemoreceptors and then excite the respiratory center; the other is to stimulate peripheral chemoreceptors, and the afferent nerve impulses are transmitted to the medulla oblongata through the sinus nerve and vagus nerve. Both reflexively deepen and accelerate respiratory movements and increase lung ventilation.

[0003] Deficiencies of existing technology:

[0004] Currently, if gas is to be administered to a patient, two separate pipelines are required, which are connected via adapters. This increases processing costs and is complex to assemble. The user needs to carry two pipelines, making operation inconvenient. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solutions: a dual-tube nasal oxygen cannula structure, comprising a first nasal oxygen cannula and a second nasal oxygen cannula, the first nasal oxygen cannula and the second nasal oxygen cannula being arranged in parallel, a double-tube connector being provided at one end of the first nasal oxygen cannula and the second nasal oxygen cannula, and a nasal rack being provided at the other end of the first nasal oxygen cannula and the second nasal oxygen cannula.

[0007] Preferably, the double-tube connector is trumpet-shaped, and the double-tube connector converts the first nasal oxygen tube and the second nasal oxygen tube into one channel.

[0008] Preferably, one end of the nasal bridge is connected to the first nasal oxygen tube, and the other end of the nasal bridge is connected to the second nasal oxygen tube.

[0009] Preferably, the first nasal oxygen tube, the second nasal oxygen tube and the double-tube connector are made of PVC.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] The double-tube nasal oxygen cannula structure is provided with a first nasal oxygen cannula and a second nasal oxygen cannula. One end of the first nasal oxygen cannula and the second nasal oxygen cannula are integrally provided with a double-tube joint. The double-tube joint converts the first nasal oxygen cannula and the second nasal oxygen cannula into one channel, eliminating the need for an adapter, thereby reducing processing costs and assembly requirements. The other ends of the first nasal oxygen cannula and the second nasal oxygen cannula are separately provided with a nasal bridge, one end of the nasal bridge is connected to the first nasal oxygen cannula, and the other end of the nasal bridge is connected to the second nasal oxygen cannula.
