Multifunctional sputum suction device

Abstract

The invention discloses a multifunctional sputum suction device. The multifunctional sputum suction device comprises a ventilation structure, an air bag and a sputum suction assembly, wherein the ventilation structure is used for communicating an airway of a patient with the outside; the air bag is arranged at the front end of the ventilation structure and can expand to cover an airway opening of the patient; and the sputum suction assembly penetrates through the ventilation structure and the air bag, and the front end of the sputum suction assembly can stretch into the airway of the patient to discharge secretions in the airway. The multifunctional sputum suction device is simple in structure, low in placement and operation difficulty, capable of building an artificial airway in the oral cavity of the patient, reliable in ventilation, small in airway mucosa damage, high in success rate and capable of efficiently discharging airway secretions of the patient and reducing vomiting and aspiration caused by sputum suction stimulation of the patient.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a multifunctional sputum suction device. Background technique [0002] In clinical practice, some patients need to use a sputum suction device for auxiliary sputum suction. The current sputum suction device is usually composed of an oropharyngeal ventilation structure and a disposable sputum suction tube. For patients who cannot cooperate (such as in a coma or under anesthesia) It can be said that the above-mentioned sputum suction device can realize the sputum suction effect, but for patients who still have resistance consciousness, the sputum suction device has the following limitations: [0003] 1) For patients who do not cooperate with sputum suction, it is difficult to insert the oropharyngeal ventilation structure into the oral cavity and reach the throat, making it difficult to establish an effective sputum suction channel; [0004] 2) The end of the oropharyngeal ventil...

AI Technical Summary

Problems solved by technology

[0003] 1) For patients who do not cooperate with sputum suction, it is difficult to insert the oropharyngeal ventilation structure into the oral cavity and reach the throat, making it difficult to establish an effective sputum suction channel;

[0004] 2) The end of the oropharyngeal ventilation structure can be blocked by the base of the patient's tongue, so that the sputum suction tube cannot go deep into the throat to effectively suck sputum;

[0005] 3) The oropharyngeal ventilation structure and suction tube are hard, and improper operation often causes damage to the upper respiratory tract mucosa of patients;

[0006] 4) The oropharyngeal ventilation structure does not have the function of airway protection. Under the stimulation of sputum suction, it may cause the patient to vomit and aspiration, and then develop aspiration pneumonia, which significantly increases the length of hospital stay and is a risk factor for poor prognosis of the patient.
