Background
Tracheal intubation is prone to ventilator-associated pneumonia, wherein the retentate on the tracheal intubation balloon is an important source of ventilator-associated pneumonia pathogen, and continuous subglottal aspiration or intermittent subglottal aspiration is an important means to prevent its occurrence. Chinese patent document CN 215350997U discloses a continuous subglottic suction flushing device, which comprises a sputum storage bottle, wherein the top of the sputum storage bottle is connected with a negative pressure pipeline and a first suction pipeline, one end of the negative pressure pipeline is connected with a negative pressure device, one end of the first suction pipeline is connected with a three-way joint, the other two channels of the three-way joint are respectively connected with a second suction pipeline and a flushing pipeline, and a rotary valve for adjusting the channel communication is arranged in the three-way joint. The second suction pipeline is inserted under the glottis of the patient, the rotary valve is communicated with the first suction pipeline and the second suction pipeline, the negative pressure device is opened, and sputum under the glottis of the patient is sucked into the sputum storage bottle. The scheme realizes the free switching of subglottal duct drainage and airway drainage without switching the connecting pipes. Chinese patent document CN 218356794U discloses a sputum aspirator with double aspiration function, which is easy to operate and has high safety, and comprises a negative pressure aspirator, a subglottal aspiration tube, a control valve, an infusion apparatus and a sputum collector, wherein one end of the subglottal aspiration tube is inserted into a human body and extends to above a balloon; the sputum collector comprises a transparent container, a connecting pipe and a negative pressure pipe, and the other end of the negative pressure pipe is connected with the negative pressure aspirator; the control valve is provided with a negative pressure valve end, a flushing valve end, a suction valve end and a control knob; the connecting pipe is connected with the negative pressure valve end; the subglottic suction tube is connected with the suction valve end; the flushing valve end is connected with the infusion bottle through an infusion apparatus; the connecting pipe and the transfusion device are connected with the subglottal suction pipe by controlling one of the control knobs. The sputum aspirator with double suction and drainage functions can switch the connection pipe, the transfusion device and the subglottal suction pipe at any time, and is suitable for pressure flushing and protecting the mucosa of a patient.
And secondly, the negative pressure of clinical sputum aspiration is selected to be 300-400 mmHg for adults, and 100-150 mmHg is used for intermittent subglottal aspiration, namely, the pressure under the intermittent subglottal aspiration is about 1/3 of the sputum aspiration pressure. In clinical work, nursing staff habitually completes sputum aspiration operation, after flushing dirt in the negative pressure connecting pipe, the suction pipe department under the glottis is connected without adjusting negative pressure, thereby lead to suction pressure under the glottis to be too big, increase mucous membrane damage risk, exist the connecting pipe after sucking the drainage tube under the glottis simultaneously and wash the aseptic operating principle that does not satisfy clinical sputum aspiration.
The difference between subglottic suction pressure and airway drainage pressure is not considered in the two prior art, so that after the control valve is adjusted, the pressure of the negative pressure source needs to be adjusted, and the pressure adjusting step is easily ignored or omitted, thereby causing damage to subglottic mucosa.

The utility model is characterized in that: through the regulation of the flow regulating valve on the branch connecting pipe I and the branch connecting pipe II, the negative pressure distribution proportion of the branch connecting pipe I and the branch connecting pipe II is changed. The negative pressure value of the negative pressure source is kept between 300 mmHg and 400mmHg, and under the conventional state, the flow regulating valve of the branch connecting pipe I is in a normally open state, and only the flow regulating valve on the branch connecting pipe II is required to be closed and opened. When the sputum is sucked by the branch connecting pipe I, the flow regulating valve on the branch connecting pipe II is closed, and then the negative pressure of the negative pressure source is used for sucking the sputum at the end part of the tracheal cannula. When the sputum under the glottis needs to be sucked, the flow regulating valve on the branch connecting pipe II is opened, so that the negative pressure value of the negative pressure source is respectively shared by the branch connecting pipe I and the branch connecting pipe II. The branch connecting pipe I still keeps certain negative pressure, can be used for further attracting residual sputum attached to the inner wall of the branch connecting pipe I, and is favorable for cleaning the branch connecting pipe I.

In one embodiment, the tracheal cannula is provided with a subglottal flushing tube, one end of the subglottal flushing tube is connected to the air bag, and the other end of the subglottal flushing tube is connected to the flushing fluid container. When more sputum or secretion is in the subglottal place, the subglottal flushing pipe is in favor of the dilution of the sputum when the normal saline is dripped into the subglottal flushing pipe, so as to facilitate the suction and removal.
Preferably, the connection point of the branch connection pipe II and the branch connection pipe I is close to the front end of the branch connection pipe I, namely the length of the main connection pipe is larger than that of the branch connection pipe I as much as possible. The normal saline can be cleaned to a certain extent through the main connecting pipe, which is beneficial to cleaning the three-way negative pressure pipe.
In one embodiment, the aperture of the branch connecting pipe II is 1/4-1/3 of the aperture of the branch connecting pipe I. The negative pressure duty ratio of the branch connecting pipe I and the branch connecting pipe II can be roughly distributed through the aperture ratio.
Preferably, the aperture of the branch connecting pipe I is 9mm, and the aperture of the branch connecting pipe II is 3mm.
In one embodiment, the sputum reservoir is provided with a negative pressure connecting pipe which is communicated with the main connecting pipe of the sputum reservoir and the three-way negative pressure pipe.
Preferably, the negative pressure connecting pipe is provided with a plunger type connector for being connected with the three-way negative pressure pipe, and a hole is formed in the side face of the plunger type connector. The plunger type connector is inserted into the end part of the main connecting pipe of the three-way negative pressure pipe, after the hole is attached to the inner wall of the end part of the main connecting pipe, the negative pressure suction is beneficial to increasing the connection firmness between the plunger type connector and the end part of the main connecting pipe, reducing the probability that the plunger type connector is unintentionally disconnected by external force, and being beneficial to the smooth implementation of sputum suction work.
In conclusion, the utility model has the advantages of simple structure and convenient use, not only realizes the convenient adjustment of subglottal suction pressure and airway drainage pressure, but also has relatively smaller probability of subglottal mucosa being damaged by negative pressure.
