AI Technical Summary
Existing oral suction devices suffer from low suction efficiency and high risk of injury during operation, especially in scenarios with complex oral anatomy and extensive secretion distribution, where they are difficult to completely suction and are prone to causing mucosal damage.
An oral suction device combining a soft fan-shaped suction bag and a multi-directional contactor was designed. It includes a columnar contactor and a lateral contactor in the front and lateral suction areas. The multi-directional suction component can cover the pharynx and both cheeks at one time. Combined with the thumb pressing groove to control the suction on and off, it improves the safety of operation.
It achieves efficient and safe sputum suction, reduces the risk of mucosal damage, and ensures ease of operation and thorough suction, making it particularly suitable for emergency sputum suction scenarios.

Abstract
Claims
1. An oral sputum suction device, characterized by, include: Soft suction bag, connecting rod, multi-directional suction assembly; The soft suction bag has a fan-shaped structure with a preset curvature. One end of the bag is connected to the connecting rod, and the other end is provided with a front suction area and lateral suction areas symmetrically distributed on both sides of the front suction area. The multi-directional suction component is provided in the front suction area and the two lateral suction areas. The connecting rod has a through-axial main suction channel inside, which communicates with the internal space of the soft suction bag. An opening and closing element is provided at the end of the main suction channel away from the soft suction bag, and the opening and closing element and the main suction channel form a fluid flow control. The multi-directional suction component includes at least four columnar contacts disposed in the front suction area and at least two pairs of lateral contacts in the lateral suction area, wherein each columnar contact and lateral contact is provided with a corresponding suction branch, and the plurality of suction branches are located in the internal space of the soft suction bag and are all connected to the main suction channel.
2. The oral sputum suction device of claim 1, wherein, In the plurality of columnar contacts disposed in the front end attraction area, each columnar contact is arranged in a linear array along a fan-shaped radial direction.
3. The oral sputum suction device of claim 1, wherein, Multiple lateral contacts on one of the lateral attraction areas are symmetrically arranged with multiple lateral contacts on the other lateral attraction area, and each lateral contact forms an angle of 20°-50° with the fan-shaped plane of the soft attraction bag.
4. The oral sputum suction device of claim 1, wherein, The opening and closing element is a thumb pressing groove provided on the outer wall of the connecting rod, which closes the main suction channel by pressing with the thumb.
5. The oral sputum suction device of claim 1, wherein, The internal space of the soft suction bag includes a primary manifold and a buffer decompression chamber, wherein the input end of the primary manifold is connected to each suction branch, and the buffer decompression chamber is provided with an elastic deformable diaphragm and is connected to the main suction channel.
6. The oral sputum suction device of claim 5, wherein, Each attraction branch does not interfere with the others.
7. The oral sputum suction device of claim 1, wherein The columnar contact has a Shore hardness of 25A-35A, and the lateral contact has a Shore hardness of 20A-25A.
8. The oral sputum suction device of claim 1, wherein, The connecting rod is made of polypropylene, with a Shore hardness of 60D-80D at the end near the soft suction bladder and 40D-50D at the end away from the soft suction bladder. The surface of the connecting rod is provided with an anti-slip thread structure.
