Automatic sputum suction system capable of preventing tracheal cannulas from leaking liquid and sputum suction method thereof

Abstract

The invention discloses an automatic sputum suction system capable of preventing tracheal cannulas from leaking liquid and a sputum suction method thereof, which belong to the technical field of trachea cannulas. The automatic sputum suction system comprises a tracheostomy tube, the tracheostomy tube is provided with a closure air bag and a sputum suction port, the sputum suction port is close toone side of the closure air bag; the sputum suction port is formed in the side, close to the mouth, of the closure air bag in the using process, the sputum suction port is communicated with the exterior of the tracheostomy tube; sputum suction and air bag loosening can be automatically carried out according to set time; the airway of the patient can be relaxed timely and accurately; medical workers do not need to strictly remember the relaxation time of an intubation air bag of each patient all the time and operate the intubation air bag; moreover, the system can be set into different pressurevalues according to the pressure requirements of each patient, and each patient only needs to accurately adjust the air pressure of the blocked air bag once when the same patient air bag is deflatedand then inflated each time, so that the inflation air pressure precision is standardized.

Description

technical field [0001] The invention relates to the technical field of tracheal intubation, in particular to an automatic sputum suction system and a sputum suction method capable of preventing liquid leakage from the tracheal intubation. Background technique [0002] Tracheotomy is to incise the cervical trachea and insert a metal tracheal cannula and a silicone cannula. It is a common operation to relieve dyspnea caused by laryngogenic dyspnea, respiratory dysfunction or retention of lower airway secretions. [0003] This kind of operation needs to use tracheostomy intubation, and this device has been very mature, and product performance structure and composition adult use tracheostomy intubation mainly by outer intubation, fixed wing, inner intubation (reusable or disposable) use), an introducer, and a fixing belt; if there is a cuff, it should also have an indicator balloon and an inflation tube; some models are equipped with an extubation plug; some inner cannula with a...

Problems solved by technology

[0005] However, this will bring a greater workload to experienced medical staff. This kind of intubation needs to pump out all the blocked secretions or reflux within 2-3 hours, and then deflate the airbag to make the patient's Relax and rest the airway for 10-15 minutes to restore normal airway pressure and blood microcirculation and prevent damage to the airway mucosa. Stable time, but the operation and intubation time of each patient is different, which leads to the different relaxation time of each patient, and the relaxation time of each patient is also different, which gives the nurse who records the time It has caused huge troubles. Once the number of patients is large and the intervals between patients are different, it is very likely to miss, make mistakes, and repeat operations, so that patients and medical staff are very distressed. Now a kind of highly automated sputum suction is needed. A system to relax the trachea to solve this time recording and manipulation problem

[0006] Moreover, some people have relatively thick airways, and the airbag air pressure may not be enough, resulting in a loose seal, while some patients have relatively thin airways, air pressure may cause excessive airway pressure, and the airbags may squeeze the patient's airway excessively, causing discomfort , so every time the airway is relaxed, the medical staff need to accurately adjust the inflation pressure of the airbag again, so that different patients will feel comfortable, which makes the workload huge;

[0007] Manual operation is not only difficult to control the pressure, but even the most experienced medical staff can hardly achieve the same inflation every time, and carefully adjust the air pressure of the air bag every time, the medical staff do not have so much energy to Doing such a seemingly simple but very difficult job, in this way, both patients and medical staff are troubled
