Disposable sputum suction bottle

Abstract

The invention provides a disposable sputum suction bottle. The disposable sputum suction bottle comprises a sputum suction bottle body, a negative pressure tube connecting mechanism which is connectedwith the sputum suction bottle body, and a sputum suction tube connecting mechanism which is connected with the sputum suction bottle body; the sputum suction tube connecting mechanism comprises a rotary knob, a threaded rod, a pressing plate, an elastic air bag, a mounting base, a connecting tube, an annular pressure applying air bag and a connecting sleeve; the upper surface of the sputum suction bottle body is fixedly connected with the connecting sleeve communicating with the interior of the sputum suction bottle body, and a groove is formed in the connecting sleeve; the annular pressureapplying air bag matched with the groove is connected into the groove; the mounting base is further fixedly connected to the upper surface of the sputum suction bottle body; the elastic air bag is fixedly connected into the mounting base; and the elastic air bag communicates with the annular pressure applying air bag through the connecting tube; and a threaded through hole is formed in the upper surface of the mounting base. The disposable sputum suction bottle provided by the invention has the advantage that the working safety of medical personnel is improved.

Description

Technical field[0001]The invention relates to the field of medical equipment, in particular to a disposable sputum suction bottle.Background technique[0002]Sputum suction refers to a method of sucking secretions from the respiratory tract through the oral cavity, nasal cavity, and artificial airway (tracheostomy) to keep the airway open and prevent complications such as aspiration pneumonia, atelectasis, and suffocation. It is indicated for comatose patients, sputum that is particularly likely to be asphyxiated, and patients who require intratracheal administration, injection of contrast agents or diluted sputum.[0003]When sucking sputum, a sputum suction bottle is needed. The existing sputum suction bottle is generally connected to the suction tube through a threaded seal. When the sputum suction bottle is replaced, the medical staff can easily interact with the suction when rotating the screw seal. Contact with the exit of the sputum tube, so that medical staff have a greater chan...

AI Technical Summary

Problems solved by technology

[0003] When sucking sputum, it is necessary to use a sputum suction bottle. The existing sputum suction bottle is generally connected to the sputum suction tube through a threaded seal. The outlet of the sputum tube is in contact, so the probability of medical staff coming into contact with the suctioned sputum is relatively high, which affects the safety of medical staff's work
