Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a high-flow nasal oxygen tube capable of detecting carbon dioxide. Background Technology

[0002] Nasal oxygen cannulas are a common medical device primarily used to deliver oxygen to patients to increase blood oxygen levels and arterial oxygen saturation, correct hypoxia symptoms, and ensure patient safety. This device is simple, inexpensive, convenient, and comfortable, and does not interfere with the patient's normal eating and drinking.

[0003] With the advancement of medical technology, traditional nasal cannulas can no longer meet the clinical need for precise monitoring of patients' respiratory status. Therefore, nasal cannulas with carbon dioxide detection have emerged, capable of not only delivering oxygen but also collecting and monitoring carbon dioxide at the end of exhalation. This new type of nasal cannulas is particularly important for patients requiring respiratory support, such as those with chronic obstructive pulmonary disease (COPD), asthma, or respiratory failure. Nasal cannulas with carbon dioxide detection can monitor the concentration of carbon dioxide at the end of exhalation in real time, providing doctors with crucial information to assess the patient's condition, determine if carbon dioxide retention or type II respiratory failure is present, and offer important guidance for adjusting treatment plans.

[0004] While nasal oxygen cannulas with carbon dioxide detection offer significant advantages in clinical applications, current technology has several limitations. The most significant issue is the fixed carbon dioxide detector head, which hinders effective monitoring for patients breathing through a single nostril, or those with pathological or habitual oral breathing. The fixed detector head also limits the device's adaptability and comfort. Therefore, developing an easily adjustable nasal oxygen cannulas that can accommodate different patients' breathing patterns is crucial for improving monitoring accuracy and patient comfort. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a high-flow nasal oxygen cannula capable of detecting carbon dioxide, comprising:

[0006] The nasal oxygen head has a lanyard for securing it to the patient's head. The bottom of the nasal oxygen head is connected to a nasal oxygen cannula for transmitting oxygen. The other end of the nasal oxygen cannula is connected to an oxygen supply connector. The other end of the oxygen supply connector is fixedly connected to an oxygen supply device. Several retaining rings are fitted on the nasal oxygen cannula, and carbon dioxide detectors are fixedly connected to the retaining rings. A universal tube is fitted around the outer periphery of the carbon dioxide detector.

[0007] Furthermore, it also includes a rotary connector, one end of which is movably connected to the bottom of the nasal oxygen head, and the other end of which is fixedly connected to the nasal oxygen cannula.

[0008] Furthermore, it also includes two lanyard buckles. The nasal oxygen head includes two oxygen supply tubes and a fixing frame. The oxygen supply tubes are used to insert into the patient's nasal cavity to supply oxygen. Both ends of the fixing frame are respectively connected to one end of the two lanyard buckles, and both ends of the lanyard are respectively connected to the other end of the two lanyard buckles.

[0009] Furthermore, the nasal oxygen cannula and the oxygen supply end connector also include a direct connector and an adapter. The nasal oxygen cannula is fixedly connected to the direct connector, the other end of the direct connector is fixedly connected to the adapter, and the other end of the adapter is fixedly connected to the oxygen supply end connector.

[0010] Furthermore, a protective sleeve is fitted at the connection point between the nasal oxygen cannula and the direct connector.

[0011] Furthermore, a silicone sleeve is fitted at the connection point between the oxygen supply connector and the oxygen supply equipment.

[0012] Furthermore, it also includes a fixing mechanism, which includes a fixing block, a fixing ring, and a fixing clamp. The fixing block is fitted onto the direct connector and has a hole on it. The fixing ring passes through the hole on the fixing block, and the fixing clamp passes through the fixing ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] By setting up a retaining ring and a carbon dioxide detection head, carbon dioxide can be selectively detected in the patient's left or right nostrils or mouth. While providing oxygen therapy, it can more effectively monitor the concentration of carbon dioxide exhaled by the patient. The carbon dioxide concentration value and its change waveform can reflect the patient's corresponding respiratory ventilation and oxygen metabolism status, which can help doctors detect some indirect and inconspicuous pathological phenomena in a timely manner or early. The angle between the nasal oxygen tube and the nose can be adjusted as needed, and the sampling port position can be selected. This is of positive significance for the treatment of patients with uninasal breathing and oral breathing. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the technical solutions in the specific embodiments of this utility model are clearly and completely described below to further illustrate this utility model. Obviously, the specific embodiments described are only a part of the embodiments of this utility model, and not all of them.

[0022] like Figures 1-4 As shown, the high-flow nasal oxygen cannula capable of detecting carbon dioxide includes a nasal oxygen head 2, a lanyard 1 for fixing to the patient's head, the lanyard 1 being made of elastic material, a nasal oxygen cannula 3 for transmitting oxygen connected to the bottom of the nasal oxygen head 2, an oxygen supply connector 4 connected to the other end of the nasal oxygen cannula 3, the other end of the oxygen supply connector 4 being fixedly connected to and connected to an oxygen supply device, a number of retaining rings 5 ​​being fitted on the nasal oxygen cannula 3, a carbon dioxide detection head 6 being fixedly connected to the retaining rings 5, the retaining rings 5 ​​being made of silicone material, a universal tube being fitted around the outer periphery of the carbon dioxide detection head 6, the orientation of the carbon dioxide detection head 6 being freely selectable around the outer periphery of the nasal oxygen cannula 3, thereby adapting to the carbon dioxide detection needs of different positions in the patient's left and right nostrils and oral cavity. The nasal oxygen head 2 includes two oxygen delivery tubes 21 and a fixing frame 22. The oxygen delivery tubes 21 are used to insert into the patient's nasal cavity to supply oxygen, and the fixing frame 22 is used to connect the hanging rope 1. The overall shape of the fixing frame 22 is "V" shaped, which is closer to the curve of the human face, thereby enhancing the stability of the nasal oxygen head 2 when the patient wears it and increasing the patient's comfort.

[0023] Oxygen from the oxygen supply device flows through the nasal cannula 3 to the nasal head 2, and then exits from the outlet tube 21 to supply oxygen to the patient's nasal cavity. Depending on whether the patient breathes through one nostril, pathologically, or habitually through the mouth, the position of the holding ring 5 and the carbon dioxide detector 6 can be adjusted to flexibly select different locations on the left and right nostrils or in the mouth for carbon dioxide detection. The carbon dioxide concentration values ​​and their changes at the end of exhalation in the left and right nostrils or the mouth reflect the patient's corresponding respiratory ventilation and oxygen metabolism status, helping doctors to detect some indirect and subtle pathological phenomena in a timely or early manner.

[0024] As a preferred embodiment, a rotary connector 7 is also included. One end of the rotary connector 7 is movably connected to the bottom of the nasal oxygen head 2, and the other end of the rotary connector 7 is fixedly connected to the nasal oxygen cannula 3. Specifically, the connection between the nasal oxygen head 2 and the rotary connector 7 is movable, allowing the nasal oxygen head 2 to rotate around the rotary connector 7. During oxygen delivery, the patient's face can move slightly, improving the patient's comfort during oxygen therapy.

[0025] As a preferred embodiment, it also includes two lanyard hooks 8. The two ends of the fixing bracket 22 are respectively engaged with one end of the two lanyard hooks 8, and the two ends of the lanyard 1 are respectively engaged with the other ends of the two lanyard hooks 8. When the lanyard 1 needs to be replaced due to insufficient elasticity after long-term use, or when it needs to be replaced according to the size of the patient's head, the lanyard hooks 8 make it easier to replace the lanyard 1.

[0026] As a preferred embodiment, the nasal oxygen cannula 3 and the oxygen supply connector 4 are further provided with a direct connector 9 and an adapter 10. The nasal oxygen cannula 3 is fixedly connected to the direct connector 9, the other end of the direct connector 9 is fixedly connected to the adapter 10, and the other end of the adapter 10 is fixedly connected to the oxygen supply connector 4. When the oxygen supply equipment needs to be connected to multiple sets of nasal oxygen cannulas, the direct connector 9 can be replaced with a multi-port connector, thereby improving the versatility of the device.

[0027] As a preferred embodiment, a protective sleeve 12 is provided at the connection point between the nasal oxygen cannula 3 and the direct connector 9. The nasal oxygen cannula 3 is a flexible tube, and the protective sleeve 12 at the connection point with the direct connector 9 can prevent the connection point from being bent when the nasal oxygen cannula 3 is pulled.

[0028] As a preferred option, a silicone sleeve 13 is provided for protection at the connection between the oxygen supply connector 4 and the oxygen supply equipment.

[0029] As a preferred embodiment, a fixing mechanism is also included, comprising a fixing block 111, a fixing ring 112, and a fixing clip 113. The fixing block 111 is fitted onto the direct connector 9 and has a hole thereon. The fixing ring 112 passes through the hole in the fixing block 111, and the fixing clip 113 passes through the fixing ring 112. To further secure the entire device, the addition of the fixing clip 113 prevents the connector from loosening due to the patient pulling on the nasal oxygen cannula 3.
