Compared with the existing technology, the invention has the benefit that
Respiratory tract sputum provided by the invention clears up system, including sputum aspirator and monitor control system automatically, with monitoring
Control system controls sputum aspirator, is carried out by the i.e. controllable enclosed sputum aspirator tube of the operating of transmission mechanism and swing mechanism to patient
Automatic suction sputum operation, operates instead of artificial suction sputum.Respiratory tract sputum provided by the invention clears up system support Hospitals at Present automatically
The enclosed sputum aspirator tube used, has the advantage that
1) from status both at home and abroad, the hair of associated pneumonia is can be effectively reduced in enclosed sputum aspirator tube when cooperating Use of respirator
Sick rate.Shown to effectively reduce patient's mouth after hospital is using enclosed sputum aspirator tube according to pertinent literature, air flue bacterium grows
Raw quantity greatly reduces the infection rate of associated pneumonia, improves the safety of patient, this is extremely closed for high risk patient
Key ensure that their safety, therefore the present invention selects enclosed sputum aspirator tube.
2) using respiratory tract sputum provided by the invention, the system of clearing up can reduce the uncomfortable degree of patient automatically, mitigate disease
People's pain sensation.By clinical analysis, using enclosed sputum aspirator tube without disconnecting ventilator, it is possible to reduce patient anxiety mitigates patient
Uncomfortable degree can also promote suction sputum process to go on smoothly.System operatio is cleared up automatically using respiratory tract sputum, can also be reduced
The anxiety degree of patient, meanwhile, the operation technique of machine is exactly the same, and different from medical staff, there is no because of medical staff
Operation that is different and generating is different, reduces the feeling of pain of patient.The spending of patient can also be reduced simultaneously, reduce expense.Enclosed
The use of sputum aspirator tube reduces the medical expense of patient, mitigates the medical burden of patient.
3) occupational exposure for reducing medical worker, reduces medical staff's disease incidence.Utilize respiratory tract phlegm provided by the invention
Automatically after cleaning system, medical staff only needs not needing every determining time check patient because sputum blocks at any time liquid
Suction sputum is overtaken, the growth of disease is greatly reduced, reduces the disease incidence of healthcare givers.Because medical staff is in critical illness
Room works, and the system of clearing up greatly reduces medical staff and contacts with germ respiratory tract sputum automatically, therefore machine operation is big
The safety of medical staff is protected greatly.
4) mitigate the workload of nurse.Nurse can become from the work of manual suction sputum timing replace enclosed sputum aspirator tube and

Dynamic, since sputum aspirator tube is clamped by the transmission mechanism in inner casing, sputum aspirator tube is rotated with the swing of inner casing.
Further, respiratory tract sputum provided by the invention is cleared up automatically in the sputum aspirator of system, and transmission mechanism is main
Including the flat wheel for clamping sputum aspirator tube and the inner casing stepper motor for driving flat wheel rotation, sputum aspirator tube can be clamped in one
Pair or the annular groove of multipair flat wheel between, at least need a pair of flat wheel that the clamping to sputum aspirator tube can be completed, examined in the present invention
The stability for considering clamping clamps sputum aspirator tube provided with two pairs of flat wheels, and two pairs of flat wheels are respectively in two inner casing stepping electricity
It is reversely rotated at the same speed under the drive of machine, so that sputum aspirator tube be driven to move forwards or backwards.It is same to be located at sputum aspirator tube in two pairs of flat wheels
It is connected between two flat wheels of side by pinion unit, so that two flat wheels of sputum aspirator tube the same side maintain synchronized rotation in the same direction
Turn.There are gap between two flat wheels in order to make sputum aspirator tube the same side, pinion unit selects the identical gear of 3 sizes,
Its diameter is less than the diameter of flat wheel, and two gears on both sides are coaxial with two flat wheels respectively, intermediate gear and meanwhile with both sides
Two gear engagements, in this way in the case where inner casing stepper motor drives a flat wheel rotation, another flat wheel is passed by gear
The drive of dynamic system can synchronized rotating Vortex.
Further, respiratory tract sputum provided by the invention is cleared up automatically in the sputum aspirator of system, and shell, which is equipped with, to be used
In the feed screw nut of the spacing for the flat wheel for adjusting sputum aspirator tube two sides, flat wheel spacing becomes larger when unscrewing feed screw nut, can replace suction
Phlegm pipe, feed screw nut is tightened after replacement reduces flat wheel spacing to hold sputum aspirator tube, and passes through adjusting screw nut
Flat wheel can be adjusted to the size of the chucking power of sputum aspirator tube so that sputum aspirator tube under the clamping action of flat wheel can preferably with
The rotation of flat wheel and move forwards or backwards.
Respiratory tract sputum automatic cleaning method provided by the invention, by monitor control system realize to sputum aspirator from
Dynamic operation and control can be realized the function of automatic push forward, backward push and sputum aspirator tube rotation, can replace medical care people
The manual operation of member carries out all basic suction sputums to patient and operates.This method can ensure the accuracy of sputum aspirator tube push,
The safety for guaranteeing patient, has accomplished the suction sputum of highly effective and safe.
