Description
Technical field
This utility model relates to medical instruments field, particularly a kind of respirator atomising device.
Background technology
ICU patient is often because a variety of causes need be accepted nebulae inhalation, particularly for the patient who has many artificial airways of having to carry out mechanical ventilation because when asthma, thick sputum, laryngeal edema, need atomizing to alleviate myxedema and reach control and infect, make the thick sputum dilution to be convenient to remove purposes such as reaching unimpeded respiratory tract to help patient to remove air flue spasm relieving asthma, antiinflammatory.But at present for the patient who whether has the artificial airway, and have patient that whether artificial airway carry out mechanical ventilation and carry out nebulae inhalation and need dispose different atomising devices, use the patient of the respirator special module that to buy producer at present that need atomize just to be achieved, do not wait for 3 ~ 60,000 yuan and dispose atomizing module needs, cost an arm and a leg, general hospital all selects to abandon, this has brought great inconvenience for the nebulae inhalation of clinical patient, and dispose different atomising devices to adapt to the patient of disease different phase, patient and section office all will additionally increase disbursement, so both increase the cost of section office, also increased the weight of patient's burden.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of respirator atomising device, can cooperate respirator to realize nebulae inhalation with lower cost.
For solving the problems of the technologies described above, the technical scheme that this utility model adopted is: a kind of respirator atomising device, bottle are provided with nebulizer outlet and nebulizer import, bottle cap is connected with bottle, bottle cap is provided with air inlet pipe, and air inlet pipe is connected with mist pipe, and mist pipe is connected with the atomizing suction pipe;
Described air inlet pipe is provided with reversal valve, and the control end of reversal valve is communicated with nebulizer outlet and nebulizer import respectively, is provided with restrictor ring in nebulizer outlet or the nebulizer import.
In the described reversal valve, the spool two ends are provided with piston, and the diameter of piston is greater than the internal diameter of restrictor ring.
The bottom becomes inverted cone in the described bottle.
The outlet of described nebulizer with contain mouth and be connected.
Described nebulizer outlet is connected with adaptor.
Difficult point of the present utility model is the conversion of respirator between " exhaling " and " suction ", promptly in pipeline, provide oxygen in the time of " suction ", then the process that respirator is discharged carbon dioxide when " exhaling ", and the nebulizer of joining outward is the atomizing that is realized by external oxygen, the gas pushing quantity of external oxygen is 10L/min, and the oxygen of joining outward is difficult to and the respiratory frequency of respirator matches, like this Wu Hua medicinal liquid some will slattern, for example in the process of " exhaling ", the medicinal liquid of atomizing can be discharged from respirator along with the air-flow of breathing out, even enters into the respirator that might corrode costliness in the respirator, for example the pick off of costliness in the respirator.
The respirator atomising device that this utility model provides, by reversal valve is set on air inlet pipe, thereby the oxygen supply that has realized atomizing is consistent with the frequency of breathing, has avoided the waste of the medicinal liquid of atomizing, has also avoided the medicinal liquid of atomizing to corrode respirator; This utility model drives the piston in the reversal valve by the pressure differential between nebulizer outlet and the nebulizer import, thereby drives the motion of change-over valve core, has realized the break-make of air inlet pipe; Because the diameter of piston is greater than the internal diameter of nebulizer outlet and/or nebulizer import, the driving force of generation is enough to drive the spool commutation in the reversal valve.
The atomising device cost of manufacture that this utility model provides is cheap, about 30 ~ 50 yuan, has reduced patient's burden with price calculating then greatly; Easy to connect, simple to operate; Because what adopt is the mode of high-speed gas atomization, the mist amount is big, and droplet is small, and the equivalent medical liquid atomizing is finished efficient than the like product height and even, and is effective; Product value for clinical application of the present utility model is big, and marketing has a extensive future.

The specific embodiment
In Fig. 1, a kind of respirator atomising device, bottle 8 are provided with nebulizer outlet 1 and nebulizer import 7, and bottle cap 2 is connected with bottle 8, and bottle cap 2 is provided with air inlet pipe 5, and air inlet pipe 5 is connected with mist pipe 6, and mist pipe 6 is connected with atomizing suction pipe 9; External oxygen enters mist pipe 6 from air inlet pipe 5, mist pipe 6 is provided with a through hole in a side of nebulizer outlet 1, external oxygen passes through at a high speed in atomizing suction pipe 9 upper ends, the negative pressure that produces is with medicinal liquid sucking-offs in the bottle 8, and atomized by high speed airflow, the air-flow of atomizing is from nebulizer outlet 1 ejection.
Described air inlet pipe 5 is provided with reversal valve 3, and the control end of reversal valve 3 is communicated with nebulizer outlet 1 and nebulizer import 7 respectively, is provided with restrictor ring 10 in nebulizer outlet 1 or the nebulizer import 7.
In the described reversal valve 3, spool 4 two ends are provided with piston 11, and the diameter of piston 11 is greater than the internal diameter of restrictor ring 10.Wherein the diameter of piston is also greater than the diameter of spool 4, and, the diameter of air inlet pipe 5 is less with respect to the latus rectum of nebulizer outlet 1 and nebulizer import 7, so only needing small pressure reduction and small stroke is that actuatable valve core 4 is realized commutation, a position is used for air inlet pipe 5 is connected, and another position makes external oxygen emptying.Making and producing pressure difference method between nebulizer outlet 1 and the nebulizer import 7 is the restrictor ring 10 that a less latus rectum is set within it, generally should be arranged in the nebulizer import 7, the internal diameter of nebulizer outlet 1 and nebulizer import 7 is 2-2.5cm, the internal diameter of restrictor ring 10 adopts the latus rectum of 1cm, greater than the latus rectum of tracheal intubation 0.8cm, can not influence and supply gas or aerofluxus.
The bottom becomes inverted cone in the described bottle 8, and (8 ~ 20ml), the outside is provided with 3 feet, the stability when keeping cup to place to have a milliliter scale on the outer wall;
During use device of the present utility model is connected between respirator loop and patient's the tracheal intubation joint, when air-breathing, the oxygen that respirator comes is through restrictor ring 10 in nebulizer outlet 1 or the nebulizer import 7, produce pressure differential, then there is the part air-flow to enter into reversal valve 3, the piston 11 that promotion is connected with spool 4, spool 4 is moved to the left, air inlet pipe 5 is switched on, external oxygen enters in the mist pipe 6 from air inlet pipe 5, and forms high velocity air above atomizing suction pipe 9, and high speed airflow forms negative pressure above atomizing suction pipe 9, with medicinal liquid sucking-offs in the bottle 8, and atomized by high speed airflow.When exhaling, by the piston that respirator produces negative pressure or is connected with spool 4 by the air-flow promotion of initiatively breathing out, spool 4 moves right; air inlet pipe 5 is communicated with evacuation port, and external oxygen is discharged from, and then medicinal liquid can not be atomized; thereby avoided the waste of medicinal liquid, protected expensive equipment.
Described nebulizer outlet 1 with contain mouth 13 and be connected; Can be suitable for not having artificial airway patient's nebulae inhalation.
Described nebulizer outlet 1 is connected with adaptor 12; Adaptor 12 mates with the respirator loop, so just can be suitable for accepting respirator Failure Treated with Mechanical Ventilation patient's nebulae inhalation.
