Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a device for detecting dry nose. Background Art

[0002] The nose is a vital organ for the human body, responsible for important functions such as respiration, smell, immunity, and protection. The nasal mucosa is the first line of defense for the human respiratory tract to contact the external environment. It can sense external stimuli such as temperature, humidity, and odor, thereby regulating the function of the mucociliary transport system, secreting mucus to absorb bacteria, dust, microorganisms, etc. in the air, and expel large particles of harmful substances. It is an important protective barrier for the human body. At the same time, the nasal mucosa also has the function of heating and humidifying the inhaled air from the outside world, so that the temperature and humidity of the gas flowing through the nasal cavity to the lower respiratory tract (bronchi and lungs) are similar to the human internal environment (37°C, nearly 100% humidity). However, the nasal mucosa is very sensitive, which is related to the presence of a large number of capillaries, glands, and peripheral nerves. Any external stimulation may cause damage to the nasal mucosa, thereby causing respiratory diseases such as rhinitis, sinusitis, and bronchial asthma.

[0003] Nasal dryness (dry nose) is a common complaint and symptom in rhinology, with a high incidence, affecting approximately 6% of the world's population. Symptoms of dry nose vary greatly in severity, ranging from subjective perception to objective visible changes in the nasal mucosa (nasal mucosal atrophy, wrinkling, and inferior turbinate atrophy). Such patients also commonly complain of nasal itching, nasal burning, nosebleeds, and nasal congestion (reflex nasal congestion). At the same time, dry nose is often accompanied by dryness symptoms from other organs, such as dry eyes, dry throat, and dry mouth. This leads to decreased nasal water content, decreased mucociliary transport system function, a decrease in goblet cells and fibroblasts in the mucosa, decreased nasal sensitivity, and nasal hyperventilation. This in turn leads to increased mucosal fragility, prone to bleeding, crusting, and cracking, causing problems for people's normal work, life, and study. The causes of dry nose are relatively complex, with the most common being related to lifestyle and living environment. The number of patients suffering from dry nose south of the Qinling Mountains and the Huaihe River in my country is significantly lower than that in the north. In a certain city, the number of patients complaining of dry nose within one month of indoor renovation (indoor humidity <50%) is significantly higher than that of permanent residents in the area. In addition, excessive use of nasal decongestants (oxymetazoline, ephedrine, etc.), the use of certain chemotherapy drugs, and long-distance flights can all cause dry nasal mucosa. Currently, doctors do not have a standardized objective evaluation system when diagnosing dry nose. Instead, they often judge whether the amount of mucus secreted by the nasal mucosa is normal by asking patients whether their noses are dry. This method is easily affected by the patient's subjectivity (patients usually exaggerate symptoms), cannot be quantified clinically, and has large errors. The treatment plans provided are also not accurate enough. Simple nasal irrigation, peppermint oil and other auxiliary treatments for moisturizing and cleaning the nasal cavity often cannot provide patients with targeted individualized treatment, and it is difficult to meet patients' expectations, resulting in poor treatment effects. Most importantly, despite the availability of objective examination methods such as anterior rhinoscopy and nasal endoscopy, many patients' subjective experiences often differ from objective examination results (dissociation between subjective and objective). These patients often experience severe subjective symptoms, but objective examinations show no corresponding changes in the nasal cavity. This is a common circumstance that can easily lead to medical disputes and unnecessary consequences. The introduction of an objective evaluation system could effectively reduce the occurrence of such incidents.

[0004] Therefore, the art needs a new device for dry nose detection to solve the above problems. Summary of the Invention

[0023] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0024] See attached Figure 1 , Figure 1 The main structure of the device for nose dryness detection is shown as an example. Figure 1 As shown, the device for detecting dry nose includes a nose clip 1 that can be fixed to the nose wing or nasal septum, a connecting portion 2 connected to the nose clip 1, and a moisture detection test strip 3 detachably connected to the end of the connecting portion 2. The surface of the moisture detection test strip 1 is covered with a transparent waterproof film 31 and has an exposed portion 32 that is not covered by the waterproof film 31. When testing the moisture content of the nasal mucosa, the exposed portion 32 of the moisture detection test strip 3 is placed in contact with the nasal mucosa, and the device for detecting dry nose is fixed to the nose wing or nasal septum via the nose clip 1. The other parts of the moisture detection test strip 3 do not absorb liquid due to the isolation effect of the waterproof film 31. Only the exposed portion 32 absorbs liquid. The liquid is absorbed and spreads on the moisture detection test strip 3. After standing for a predetermined period of time, the moisture detection test strip 3 is removed and the distance the liquid spreads on the moisture detection test strip 3 is observed. This allows the moisture content of the nasal mucosa to be objectively and accurately detected.

[0025] See attached Figure 2 , Figure 2 The main structure of the moisture detection test paper is shown as an example. Figure 2 As shown, the moisture detection test paper 3 can be arranged in a long strip shape, with an exposed portion 32 located at one end of the moisture detection test paper 3. A marker 33 is provided on the moisture detection test paper 3 near the exposed portion 32. The marker can be composed of a highly hygroscopic adsorption indicator (FluoresceinSodium), which is generally in the form of dots, squares or lines. The marker 33 is coated on the moisture detection test paper 3 and covered by a waterproof film 31 to spread as the liquid extends on the moisture detection test paper, playing a striking role and facilitating the observation of the distance the liquid extends. Preferably, the moisture detection test paper 3 is marked with a scale line 34 to facilitate the measurement of the distance the liquid extends.

[0026] Continue to refer to the attached Figure 2 A color-changing temperature-indicating strip 35 is also provided on the moisture detection test paper 3 near the exposed portion 32. The color-changing temperature-indicating strip 35 is based on the thermosensitive principle and displays different colors as the temperature changes. The temperature test range of the color-changing temperature-indicating strip 35 is 30°C to 45°C. When detecting the water content of the nasal mucosa, the temperature inside the nasal cavity can be measured at the same time, providing objective guidance for the doctor and making an objective assessment of the physiological condition of the nasal cavity. Preferably, the color-changing temperature-indicating strip 35 can be arranged in an arc shape and close to the edge of the exposed portion 32, or can be arranged in a long strip shape, and its length direction is perpendicular to the length direction of the moisture detection test paper 3, but is not limited thereto.

[0027] Continue to refer to the attached Figure 2 The exposed portion 32 of the moisture detection test paper 3 is roughly circular, and the end of the connecting portion 2 has a ring 21 corresponding to the exposed portion 32, and the ring 21 is connected to the edge of the exposed portion 32. The connecting portion 2 is made of a plastic material. In this embodiment, the connecting portion 2 is an elastic wire. Figure 1 The nose clip 1 includes an arc-shaped clip arm 11 made of an elastic and moldable material. The connecting portion 2 is connected to the clip arm 11. An elastic first fixing member 12 is provided at the end of the clip arm 11. The device for nose dryness detection is fixed to the nose wing or nasal septum through the first fixing member 12. The first fixing member 12 can be made of silicone or rubber, and the clip arm 11 and the first fixing member 12 can be integrally formed.

[0028] See attached Figure 3 , Figure 3 The main structure of the apparatus for nose dryness detection according to another embodiment is shown as an example. Figure 3 As shown, the device for detecting dry nose may include two moisture test strips 3, used to test the moisture content and nasal temperature of the left and right nasal cavities, respectively. The nose clip 1 includes two curved arms 11, with the two moisture test strips 3 connected to one arm 11 of the nose clip 1 via a connecting portion 2. The two arms 11 are connected by a resilient second fixing member 13, which is used to secure the device for detecting dry nose to the nasal septum. A positioning plate 15 is also provided at the end of the arm 11. The positioning plate 15 is L-shaped and its length is perpendicular to the arm 11. When using the device for detecting dry nose, the patient lies flat on their back. The moisture test strips 3 are inserted horizontally into the nasal cavity, with the exposed portion 32 in close contact with the nasal mucosa. The entire device is secured to the nasal septum via the second fixing member 13. At this time, the positioning plates 15 are pressed against the patient's face. By adjusting the positioning plates 15 at both ends of the nose clip 1, the nose clip 1 is fixed horizontally in the middle of the nasal cavity. A handle 14 may also be provided at the end of the clamping arm 11 .

[0029] The above are preferred embodiments of the present invention and the technical principles used therein. For those skilled in the art, any obvious changes such as equivalent transformations, simple replacements, etc. based on the technical solution of the present invention, without departing from the spirit and scope of the present invention, are within the scope of protection of the present invention.
