Title:
NEGATIVE-PRESSURE ATTACHING DENTAL PAD FOR FIXATION OF TRACHEAL TUBE
Document Type and Number:
WIPO Patent Application WO/2020/147328
Kind Code:
A1
Abstract:
Provided is a negative-pressure attaching dental pad, comprising a retaining plate (2) and a groove (14); the lower half of the dental pad is designed have a curved shape according to the deformation of the tracheal tube in the oral cavity. The groove (14) has a unidirectional exhaust vent (113); there is a relatively large gap (115) between the groove (14) and the tracheal tube (2); after forcibly pressing the air out, the gap (115) is significantly reduced, and the interior thereof becomes negative pressure, thereby attaching the tracheal tube (2) to the dental pad; then a syringe is used to draw air out by means of the unidirectional exhaust vent (113) to increase the internal negative pressure in the gap (115) between the dental pad and the tracheal tube (2). By means of the negative-pressure attaching design, the greater the negative pressure, the more firmly the fixation is; furthermore, the negative pressure can slightly increase the airway of the tracheal tube (2), such that the dental pad and the tracheal tube (2) attach together; the occupied volume of the oral cavity is small, alleviating the suffering of patients and facilitating oral care, and furthermore, only one person is required to proceed, reducing human labor.
