A meterable, multifunctional and safe closed sputum suction device

Abstract

The invention discloses a meterable, multifunctional and safe closed sputum suction device. The sputum suction device installs an anti-aspiration valve on the breathing tube between the ventilator interface and the flushing tube, and rotates the outer disc during use. It realizes the opening and closing function with the inner disk, and a self-closing valve is installed on the flushing pipe. By controlling the clamping and loosening of the clip of the self-closing valve, the flushing liquid in the flushing pipe can be controlled to flow in and stop, and the valve is sucked under negative pressure. A sputum metering collector is installed between the negative pressure suction connection port. The sputum metering collector can collect sputum by rotating the relative position of the bottle body and the bottle cap, and has a metering function. This device solves the problem of flushing and suction. When the sputum tube is used, the flushing fluid enters the patient's airway and the potential risks caused by the medical staff's negligence and forgetting to close the valve of the flushing fluid. Influence of conventional sputum suction device on ventilator therapy.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a measurable, multifunctional, and safe closed-type sputum suction device. Background technique [0002] Clinically, patients with mechanical ventilation and patients with artificial airway need sputum suction nursing. When performing sputum suction operations, medical staff must, on the one hand, achieve the purpose of cleaning up sputum, and on the other hand, measure the sucked sputum and collect sputum samples, and at the same time, ensure patient safety and prevent nosocomial infections. At present, the closed sputum suction tube commonly used in clinical practice can solve the problems of interrupting ventilator treatment and airway exposure during suctioning, and prevent cross-infection, but there are still many deficiencies. First of all, there is a lack of devices to prevent aspiration. When medical staff use the existing closed sputum suction tube for sputum su...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to address potential risks to patients caused by the flushing liquid entering the patient's airway when flushing the sputum suction tube and medical staff forgetting to close the valve of the flushing liquid due to negligence in the prior art, and the closed sputum suction device The technical problem that affects the treatment of the ventilator provides a method for medical staff to accurately measure sputum and conveniently collect sputum samples. At the same time, it can effectively prevent the flushing fluid from entering the patient's airway, and prevent the patient from choking, aspiration, and suffocation. Measurable and multi-function safe closed sputum suction device
