摘要:
It is a foldable nasal cavity spray catheter (6) made from a thermoplastic elastomer or flexible, resilient material that can be delivered to a patient for patient operation and placement in the nasal cavity or nasopharynx (j) . the catheter (6) comprises a main catheter body (61) and an adapter (62). the catheter main body (61) has a flat closed end (611), a transition section (ts) from the closed end (611) to a circular outer-looking part, a normal section (s) that has an appearance circular outer, and an open end (612) opposite the flat closed end (611); a plurality of edge holes (613) are disposed near the closed end 611); If the adapter (62) and a syringe (7) are fitted, multiple strong jets of water can be sprayed into the nasal cavity and nasopharynx (j) to clear mucus and scabs. the maximum width of the transition section (ts) of the main catheter body (61) is not less than 1 mm, and the minimum thickness of its tube wall is not greater than 0.45 mm. Due to the flat closed end (611), transition section (ts), and collapsibility of the catheter main body (61), a catheter having a relatively large outside diameter can readily pass into a slit-shaped space for rinse performance. preferable in narrow and deep areas, while also preventing accidental insertion into the paranasal sinuses.trata-se de um cateter de borrifação de cavidade nasal dobrável (6) produzido a partir de um elastômero termoplástico ou material flexível e resistente, que pode ser fornecido a um paciente para operação pelo paciente, e colocação na cavidade nasal ou nasofaringe (j). o cateter (6) compreende um corpo principal do cateter (61) e um adaptador (62). o corpo principal do cateter (61) tem uma extremidade fechada plana (611), uma seção de transição (ts) a partir da extremidade fechada (611) para uma parte de aparência externa circular, uma seção normal (ns) que tem uma aparência externa circular, e uma extremidade aberta (612) oposta à extremidade fechada plana (611); uma pluralidade de
