Disposable closed phlegm suction and collection device

Abstract

The invention discloses a disposable closed phlegm suction and collection device. The device comprises a closed phlegm suction pipe body, wherein the phlegm suction pipe body comprises a Y-shaped connector and a phlegm suction pipe which are sequentially connected; a phlegm suction pipe sealing film is fixedly arranged at the outer part of the phlegm suction pipe, and a negative pressure control valve is arranged at the bottom of the phlegm suction pipe; a pipe orifice A and a port cap of the pipe orifice A are arranged at the bottom of the negative pressure control valve; the Y-shaped connector comprises a tracheal socket at the top end, a respirator connecting orifice and a drug injection opening at the lateral end; a sealing push plate is arranged between the phlegm suction pipe and theY-shaped connector and is used for controlling the phlegm suction pipe to be unblocked and closed; a transfusion medicinal bag is connected on the side wall of the pipe body between the phlegm suction pipe and the sealing push plate through a connecting pipe; a tee joint is fixedly arranged on the connecting pipe; a phlegm deposit bottle is movably connected with the pipe orifice A; a first pipebody and a second pipe body are fixedly arranged at the top of the phlegm deposit bottle, and outlets of the first pipe body and second pipe body are respectively a pipe orifice B and a pipe orifice C. The disposable closed phlegm suction and collection device can effectively solve the problem of closed phlegm collection, avoids alveoli collapse and hyoxemia of a patient and solves the problem ofcross infection of medical staff.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a disposable airtight sputum suction and collection device. Background technique [0002] With the gradual aggravation of respiratory tract patients and the increasing number of critically ill patients such as tracheal intubation and mechanical ventilation, patients often need to be treated with sputum suction. At present, the method widely used clinically to remove secretions from the artificial airway is the closed sputum suction technology, which connects the closed sputum suction tube with the artificial airway, the Y-shaped tube of the ventilator and the negative pressure suction equipment to form a closed system. The sputum operation is carried out in a relatively closed space, and there is no need to disconnect the ventilator during the treatment process, which can effectively reduce the occurrence of alveolar collapse caused by sputum suction, and can significantly reduce...

AI Technical Summary

Problems solved by technology

However, closed sputum suction and collection devices are rare, and it is impossible to achieve the purpose of avoiding interruption of the ventilator, alveolar collapse, hypoxemia, and occupational exposure of medical staff infection when collecting sputum samples for patients with respiratory infectious diseases in tracheal intubation mechanical ventilation

The existing closed sputum suction tube does not have the function of collecting sputum and keeping it as a specimen
