Meterable multifunctional safe closed sputum suction device

Abstract

The invention discloses a measurable multifunctional safe closed sputum suction device. The device is characterized in that an anti-aspiration valve is mounted on a breathing tube between a breathing machine interface and a flushing tube, opening and closing functions are realized by rotating an outer disc and an inner disc during use, a self-closing valve is mounted on the flushing tube, flowing and stopping of flushing fluid in the flushing tube can be controlled by controlling clamping and loosening of a clamp of the self-closing type valve, a sputum metering collector is installed between the negative pressure suction valve and the negative pressure suction connecting port, the sputum metering collector can achieve the sputum collecting function by rotating the relative position of a bottle body and a bottle cap, and the sputum metering collector has the metering function. According to the device, the potential risk caused by the fact that flushing fluid enters an airway of a patient when a sputum suction tube is flushed and medical staff forget to close a valve of the flushing fluid due to negligence is avoided, the medical staff can conveniently and accurately meter sputum and conveniently reserve and take sputum samples, and the influence of a closed sputum suction device on treatment of a breathing machine is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a meterable, multifunctional and safe closed sputum suction device. Background technique [0002] Clinically, patients who are mechanically ventilated and patients who have established an artificial airway need sputum suction nursing. When medical staff perform sputum suction operations, on the one hand, they must achieve the purpose of cleaning up the sputum, and on the other hand, they must measure the aspirated sputum and collect sputum samples. At the same time, they must ensure the safety of patients and prevent nosocomial infections. At present, the closed sputum suction tube commonly used in clinical practice can solve the problem of interrupting ventilator treatment during sputum suction, airway exposure to air, and prevent cross-infection, but there are still many deficiencies. First of all, there is a lack of devices to prevent aspiration. When medical personne...

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.
