Breathing is people's basic physiological function and a life support.The critical patient need carry out management of respiratory, and wherein a kind of method is exactly a tracheal intubation, sets up the artificial airway.Tracheal intubation is exactly by certain technological means, and the medical silicone tube of a suitable bore (tracheal intubation) is inserted trachea by oral cavity or nasal cavity, is breathed and relevant item by artificial or instrument management.A content of respiratory tract nursing is air flue humidification and inhales expectorant after the tracheal intubation.The present clinical tracheal intubation of using is the medical silicone tube of a front end as the inclined-plane, and the outside attaches a pressure bladder.When doing tracheal intubation, this tracheal intubation is inserted trachea, in pressure bladder, inject an amount of air, the space between sealing trachea and the tracheal intubation.Termination respirator or artificial ventilator after the tracheal intubation.Sputum aspirator tube is an elongated medical silicone tube, and front end is used to insert tracheal intubation and endotracheal suction (ets), back termination vacuum extractor.When inhaling expectorant,, unplug the connection tube of tracheal intubation rear end and respirator (artificial ventilator) by nurse operation, temporary transient interruption assisted respiartion is inserted tracheal intubation, pull within the specific limits to sputum aspirator tube, inhale expectorant with negative pressure, tracheal intubation connect respirator once more after suction expectorant finished.In critical patient management, inhale expectorant and be one repeatedly repeat, very loaded down with trivial details work, meet the staff few, when workload is big, can reduces unavoidably and inhale the expectorant number of times.As it is untimely to inhale expectorant, and it is long-pending that the sputum stasis of blood may take place, and blocks respiratory tract, and therefore pulmonary infection, respiratory failure may take place; Even the dry gradually expectorant crust that forms of sputum, cause chronic obstructive airway, and then death by suffocation takes place.Wanting the stops machine ventilation breath when inhaling expectorant is a kind of potential risks, repeatedly inhales the expectorant operation and also easily pollution is brought into patient's respiratory tract.What be worth that we note is because inhale that this technology content of expectorant is not high, the work that need often repeat and take plenty of time of nurse, be a kind of waste of manpower resource.This important work is simultaneously carried out with random very strong manual type, also is improper.

Also there is not a kind of medical device to address this problem well at present.

Summary of the invention

The critical patient, done tracheal intubation, under the situation of breathing by artificial ventilator or respirator, in order can safely, efficiently, not stop assisted respiartion, to absorb sputum in the respiratory tract for patient, alleviate nurse's working strength simultaneously, this utility model provides a kind of tracheal intubation of additional sputum aspirator tube, should add the tracheal intubation of sputum aspirator tube and can simplify the operation of suction expectorant, improve the security reliability of critical patient's management.

This utility model purpose is to improve to inhale the reliability that expectorant and mechanical ventilation are breathed in critical illness management, alleviates nurse's workload simultaneously, for management of respiratory and first aid provide a kind of new technical method and first-aid equipment.Need not change original method and custom manipulated when simultaneously the staff uses this equipment.

The technical scheme that its technical problem that solves this utility model adopts is: design one or more pipe spline structures as sputum aspirator tube at the tracheal intubation cavity wall, this pipe spline structure front opening is in tracheal intubation, end passes the tracheal intubation wall with the tubule spline structure, transition is a thin tube-like, can receive on the vacuum extractor.Than the tracheal intubation of ting model, can attach a sputum aspirator tube in it; The tracheal intubation of thick model can be attached a plurality of sputum aspirator tubes in it.A plurality of sputum aspirator tubes at the tracheal intubation inner opening in Different Plane.This tracheal intubation of attaching sputum aspirator tube, its advantage is: needn't pull up the respirator pipe when inhaling expectorant, needn't stop mechanical ventilation and breathe; Simplified the operation of suction expectorant; Alleviated nurse's workload; Improved the reliability of inhaling expectorant and mechanical ventilation breathing.If sputum aspirator tube is received on the sputum aspirator of automated management, just can realize that regularly fixed tube is inhaled expectorant, the nurse is freed from this loaded down with trivial details mechanicalness work.

The beneficial effects of the utility model are, the one or more pipe spline structures of design are as sputum aspirator tube in tracheal intubation, and simple in structure, production technology is uncomplicated.Needn't pull up the respirator pipe when inhaling expectorant, needn't stop mechanical ventilation and breathe; Simplified the operation of suction expectorant; Alleviated nurse's workload; Improved the reliability of inhaling expectorant and mechanical ventilation breathing.If sputum aspirator tube is received on the sputum aspirator of automated management, just can realize that regularly fixed tube is inhaled expectorant, the nurse is freed from this loaded down with trivial details mechanicalness work.
