Description

Technical Field

[0001] This invention belongs to the field of medical and nursing device technology, specifically a simplified and intelligent nasal oxygen tube adapter device for high-altitude use. Background Technology

[0002] Low air pressure and insufficient oxygen partial pressure in high-altitude areas commonly lead to poor peripheral circulation, large fluctuations in blood oxygen saturation, and a high risk of hypoxia in long-term residents and hospitalized patients. Currently used disposable nasal oxygen cannulas only provide oxygen and lack vital sign monitoring capabilities. Conventional finger-clip pulse oximeters are significantly affected by hand movements, low temperatures, and insufficient peripheral blood perfusion, resulting in large measurement errors and making it impossible to synchronize with oxygen administration. Existing integrated oxygen monitoring devices are complex in structure, bulky, and burdensome to wear, requiring customized consumables and incurring high costs. Furthermore, they often rely on audible and visual alarms, causing noise pollution in wards at night and disturbing patients' rest, making them unsuitable for routine monitoring of long-term bedridden patients and those requiring continuous oxygen therapy in high-altitude areas, thus limiting their clinical application.

[0003] In view of the shortcomings of existing technologies, such as separation of oxygen inhalation and monitoring, susceptibility to interference in measurement, discomfort when worn, loud alarm noise, and poor universality of consumables, this invention provides a simplified and intelligent nasal oxygen tube adapter device specifically for high-altitude areas.

[0004] The information disclosed above in this background section is only for enhancing the understanding of the background section of this invention, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

This invention enables rapid adaptation of universal nasal oxygen tubes, simultaneous blood oxygen monitoring during oxygen inhalation, silent early warning of hypoxia, and lightweight long-term wear, thus meeting the essential clinical needs of high-altitude nursing.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a simplified intelligent nasal oxygen tube adapter specifically for high-altitude areas, comprising a flexible ear loop fixing bracket, a miniature main control box, and a blood oxygen sensor detection head.

[0014] Preferably, the vibration warning module includes at least two vibration modes, corresponding to low blood oxygen warning and critical blood oxygen alarm respectively, and the vibration intensity and frequency are adjustable.

[0015] Preferably, the miniature main control box has a waterproof and dustproof sealing structure on the outside, with an overall protection level of not less than IP54, and supports daily wiping and disinfection.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0026] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0027] Example 1:

[0028] A simplified smart nasal oxygen monitoring adapter for high-altitude applications includes an ear loop flexible fixing bracket 1, a miniature main control box 2, and a blood oxygen sensor detection head 5.

[0029] The ear loop flexible fixation bracket 1 is detachably fitted onto the outside of the universal nasal oxygen tube 6. The ear loop flexible fixation bracket 1 is a medical-grade flexible silicone buckle structure that can elastically hold the body of the standard nasal oxygen tube. It is easy to install and remove, conforms to the facial contours, and does not cause obvious pressure even after long-term wear. It is compatible with various sizes of universal disposable nasal oxygen tubes and does not require customized consumables.

[0030] The pulse oximeter sensor 5 is electrically connected to the miniature main control box 2. The pulse oximeter sensor 5 is independently positioned at an external point away from the nasal oxygen supply, isolating it from interference from the oxygen supply flow, adapting to the low perfusion physiological state of people in high-altitude areas, and improving the stability and accuracy of the detection. The pulse oximeter sensor 5 is connected to the miniature main control box 2 via a flexible connecting wire 4.

[0031] The blood oxygen sensor head 5 consists of a single-point independent blood oxygen sensor 51, a light-shielding shell 52, a sensor connection wire interface 53, and a flexible adhesive pad 54.

[0032] The miniature main control box 2 contains a main control module, a vibration warning module, and a power supply module. The main control module has a built-in data processing unit and a blood oxygen threshold determination program, receiving and analyzing signals collected by the blood oxygen sensor 5 in real time. The vibration warning module is connected to the main control module and uses mechanical vibration to achieve silent alarm. The power supply module supplies power to all components. The overall design eliminates the need for a sound and light speaker structure, relying solely on vibration to provide abnormal alerts, making it suitable for nighttime use in hospital wards.

[0033] The main control module is an integrated processor 21, the power supply module is a shaped lithium polymer thin film battery 23, the vibration warning module is a bone conduction vibrator 24, and the micro main control box 2 is also equipped with a flexible circuit board 22.

[0034] The main control module is equipped with a wireless Bluetooth or wired data transmission interface, allowing connection to an external nursing terminal for data storage and export. The main control box is compact, embedding a low-power processing chip and pre-programmed with applicable blood oxygen warning threshold ranges for high-altitude areas. When the monitored blood oxygen level falls below the set standard, the main control module immediately triggers a bone conduction vibrator to continuously vibrate at a low frequency for 24 seconds, alerting the patient and medical staff to intervene promptly.

[0035] The universal nasal oxygen tube 6 is provided with a nasal oxygen tube assembly slot 3, and the nasal oxygen tube assembly slot 3 is provided with a nasal plug oxygen supply end 31.

[0036] The device has no extra protruding structures, is waterproof and wipe-resistant, meets hospital infection control and disinfection requirements, and is suitable for use in conjunction with long-term oxygen therapy for patients in general wards, internal medicine, urology, geriatrics and other departments of high-altitude hospitals.

[0037] Working principle: This device is installed on the outside of the universal nasal oxygen tube 6 via a flexible ear loop fixing bracket 1, and is worn and fixed synchronously with the nasal oxygen tube; the blood oxygen sensor head 5 continuously collects peripheral blood oxygen saturation data and transmits it to the main control module; the main control module compares it with the preset high-altitude safe blood oxygen threshold in real time, and automatically activates the vibration warning module to provide a silent reminder when the blood oxygen value is low or drops sharply in a short period of time; oxygen inhalation and blood oxygen monitoring are carried out simultaneously without interference, and the monitoring data can be uploaded and saved to an external terminal, which is suitable for 24-hour continuous oxygen inhalation monitoring of high-altitude patients.

[0038] Example 2:

[0039] In this embodiment, the flexible ear loop fixation bracket 1 adopts a dual-material composite structure: the outer layer is medical-grade silicone, and the inner layer is flexible memory metal wire, which can be shaped and adjusted in one go according to the shape of the patient's auricle, significantly improving the fit and wearing stability. An anti-slip locking structure is provided between the flexible ear loop fixation bracket 1 and the universal nasal oxygen tube 6 to prevent displacement due to the patient turning over or moving during use.

[0040] Example 3:

[0041] In this embodiment, the blood oxygen sensor 5 integrates an ambient light recognition module, which can dynamically detect external light intensity and automatically compensate for signal gain. The light-shielding outer shell 52 adopts a double-layer injection molding process, with an inner layer of black light-absorbing material and an outer layer of medical-grade soft rubber, balancing optical shielding and wearing comfort. The inner surface of the flexible, fitting pad 54 has a microporous structure to reduce skin moisture and discomfort caused by long-term contact.

[0042] Example 4:

[0043] The bone conduction vibrator 24 supports three vibration modes:

[0044] Mild hypoxemia (SpO2 81%-85%): low-frequency intermittent vibration 1Hz, lasting 2 seconds, with a 5-second interval;

[0045] Moderate hypoxemia (SpO2 76%-80%): Continuous mid-frequency vibration at 3Hz;

[0046] Critical hypoxemia (SpO2 ≤ 75%): high-frequency, intense vibration at 5 Hz, superimposed with three rapid vibration cycles.

[0047] The vibration mode can be personalized via Bluetooth connection to the nursing terminal to meet the sensory needs of different patients.
