Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical auxiliary devices, in particular to a HHT-based air blocking plug for nasal capillary bleeding. BACKGROUND

[0002] Hereditary hemorrhagic telangiectasia (HHT) is a disease characterized by capillary dilatation damage in multiple parts of the skin and mucosa, causing nasal bleeding and bleeding in other parts, and often accompanied by clinically significant arteriovenous malformations. The pathogenesis of hereditary hemorrhagic telangiectasia is still not very clear. The bleeding manifestations of the disease are related to the inherent increase in vascular mechanical fragility. The main pathological changes are the lack of elastic fibers and smooth muscle in the blood vessels, and the affected blood vessel wall is only a layer of endothelial cells surrounded by a layer of non-muscular and non-elastic loose connective tissue. The blood vessel wall is fragile and easily broken, and cannot contract, showing a hemangioma-like dilatation, which is called capillary dilatation, so it is easy to cause bleeding. The clinical manifestations include repeated bleeding in the same part, and nasal bleeding is more common. There is a lack of effective treatment in clinical practice.

[0003] In summary, there are the following technical problems in the relief process of hereditary hemorrhagic telangiectasia: due to hereditary hemorrhagic telangiectasia, normal respiratory airflow can stimulate nasal mucosa capillaries to cause bleeding. Since the disease cannot be cured, clinical treatment recommends that such patients should not breathe through the nose, but breathe through the mouth. However, mouth breathing can cause dry mouth, and patient compliance is not high, and it is also difficult to maintain over time. In clinical practice, some patients use a mask or cut the mask around the nostril position to block the flow of nasal breathing gas, slow down the flow of gas, and reduce the risk of nasal bleeding, which has a certain relief effect. However, the mask structure is externally worn and needs to be fixed behind the ear or around the head, which affects the patient's daily activities and psychology. First, the mask hinders the patient's eating and drinking movements, and the fixation to the back of the ear or the head can also cause skin damage to the patient's face. Wearing a structure around the nose can also cause psychological problems for the patient due to their difference from ordinary people. The existing paper ball structure inserted into the nasal cavity can cause unstable position, moisture, and pressure damage to the inside of the nasal cavity. SUMMARY

[0004] In view of the above problems existing in the prior art, the present application provides a HHT-based air blocking plug for nasal capillary bleeding, which is internally worn to reduce changes to the patient's facial appearance and damage to the patient's facial skin.
