NASAL ASPIRATOR
Document Type and Number:
WIPO Patent Application WO/2023/115708
Kind Code:
A1
Abstract:
A nasal aspirator, comprising an elastic aspirating ball (1) and an aspirating tube (2). The elastic aspirating ball (1) is made of flexible plastic, the interior of the elastic aspirating ball (1) is a nasal discharge cavity (11), and the side wall of the elastic aspirating ball (1) extends to be connected to the aspirating tube (2). The interior of the aspirating tube (2) is an air inlet and outlet channel (21), and the cross section of the head end of the aspirating tube (2) is an aspirating port (22). The nasal discharge cavity (11), the air inlet and outlet channel (21), and the aspirating port (22) are communicated with each other in sequence. A limiting convex ring (23) extends in the circumferential direction of the outer wall of the front section of the aspirating tube (2) in a protruding mode, the limiting convex ring (23) and the aspirating tube (2) are formed integrally, and the tube section between the limiting convex ring (23) and the aspirating port (22) is a nostril plug-in short tube section (24). When the front end of the aspirating tube (2) of the nasal aspirator is inserted into the nostril, and the limiting convex ring (23) touches and abuts against the nose, the front end of the aspirating tube (2) is inserted into the nostril depth, the limiting convex ring (23) plays a blocking role, and damage to the deep part of the nostril caused by excessive insertion is prevented.
