Description
Technical field
It is sucked out the present invention relates to a kind of special tracheal catheter and sputum and dilution instills control system.With in conduit
The tracheal catheter in suction sputum channel is provided simultaneously with drop medicine and the tracheal catheter of pipe flushing function in pipeline, can pass through extraneous phlegm
Liquid is sucked out and dilution instills set-up of control system and carries out interruption to the sputum in respiratory tract or persistently attract, while can pass through
Extraneous sputum is sucked out and dilution instills set-up of control system to being interrupted in respiratory tract or lasting dilution instills,
Belong to the field of medical instrument technology.It is suitable for the patient of any endotracheal intubation.Be particularly suitable for some need respiratory tract every
From patient, can reduce medical worker infect probability.
Background technology
Endotracheal intubation refers to being inserted into special tracheal catheter in patient's trachea by oral cavity or nasal cavity, is clinical
Common technology in curative activity.It is main be applicable in operation endotracheal anesthesia, being hospitalized gives emergency treatment to a patient and the patient of Breathing Suppotion for a long time.
For receiving the patient of trachea cannula treatment, sputum drainage and sputum dilution are the main problem of clinical treatment lung, especially
In the patient for needing respiratory tract to be isolated, how to meet the protection to medical worker as the emphasis of concern.Some are being faced
The medical staff of bed work, it is more for sputum, and be not suitable for interruption and be detached from for the patient of respiratory therapy, give medical worker
Increased great burden.Existing invention has the lasting device for attracting sputum, but such device, the extraneous merging tracheae of need are led
Suction sputum is carried out in pipe, can change the tidal volume and airway pressure of lung ventilator, cannot be satisfied with clinical respiratory therapy, while can be to suffering from
The respiratory function of person has an impact.Find that, for the larger patient of sputum viscosity, such device is also easy to block to attract simultaneously
Pipeline.Therefore it is badly in need of wanting to facilitate dilution sputum and interruption to attract and do not change clinical respiratory therapy, while avoids sputum and doctor
The device of business human contact.
Invention content
It is sucked out present invention aims at a kind of tracheal catheter of offer and sputum and dilution instills control system.It is by tracheae
Catheter main body, sputum are sucked out and dilution instills control system composition.Tracheal catheter main body is inserted into disease by oral cavity or nasal cavity
People's tracheal strips, can be sucked out by sputum and dilution instills control system and instills connecting tube to sputum channel connecting tube and dilution
Control so as to adjust in respiratory tract sputum attract and dilution instill.
The technical solution adopted by the present invention to solve the technical problems is：A kind of special tracheal catheter that the invention is related to
And sputum is sucked out and dilution instills control system and mainly instills control system including tracheal catheter main body, sputum suction and dilution
System.Wherein tracheal catheter main body includes：Tracheal catheter air bag, tracheal catheter air bag passage, tracheal catheter air chamber gas charging valve, negative pressure
Connector, sputum channel connecting tube, conduit annular sputum be logical, sputum channel in conduit, sputum suction inlet in conduit, in conduit
