Document Type and Number:
WIPO Patent Application WO/2020/073932
Kind Code:
A1
Abstract:
Disclosed is a medical intelligent sputum aspiration negative-pressure therapeutic apparatus with adjustable pressure, the apparatus comprising a therapeutic apparatus body and a drainage bottle (8), wherein a human-computer interaction interface (1), a warning device (3), an air inlet control device, a pressure release solenoid valve (6), a pressure sensor (7), a liquid level sensor (9), and an embedded microcomputer system (2) are arranged inside the therapeutic apparatus body; the human-computer interaction interface (1), the warning device (3), the air inlet control device, the pressure release solenoid valve (6), the pressure sensor (7), and the liquid level sensor (9) are all connected to the embedded microcomputer system (2), and the therapeutic apparatus is required to be connected to a negative pressure source in a hospital; and the air inlet control device is connected to the negative pressure source and the drainage bottle (8) respectively via a conduit, the drainage bottle (8) communicates with external atmospheric environment via the pressure release solenoid valve (6), and the pressure sensor (7) and the liquid level sensor (9) are arranged at the connection between the drainage bottle (8) and the therapeutic apparatus body. The therapeutic apparatus is simple in structure, the sputum aspiration pressure can be intelligently selected based on the weight of a patient during sputum aspiration, the pressure at a patient end can be maintained during aspiration therapy, and a tissue suction warning, a pressure loss warning, and a drainage volume and drainage rate warning device (3) are provided for safe use.
