Description
Technical field
The present invention relates to a kind of gastric lavage sputum aspirator, and in particular to a kind of pressure control piston pressure-controlled type gastric lavage suction sputum fills device.
Background technology
On-the-spot rescue outside hospital（Given first aid to outside abbreviation institute）The important component of emergency medicine is become.It is although anxious outside institute
It is temporary transient to rescue, emergent, but for urgent patient, effective preliminary rescue is to obtain rescue time, improve first aid success
The extremely important step of rate.At present, there is sputum, blood, vomitus etc. and blocks air flue causing patient respiration difficult in patient outside institute
Even suffocate, eat by mistake take medicine by mistake or the reason such as poisonous substance and suicide and the critical conditions such as poisoning occur and happen occasionally, often adopt
Patient is given with gastric lavage sputum aspirator and gives effective emergency processing, is tried to gain time precious to one and is seemed for further doctor's first aid in hospital
It is most important.
Traditional gastric lavage sputum aspirator includes liquid pipe, and liquid pipe one end stretches into the tracheae of patient, other end conduct as absorption edge
Operating side is provided with negative pressure device, and the also usual unicom of liquid pipe is provided with sump assemblies and is used for Recycling of waste liquid, avoids waste reflux extremely
Negative pressure device, is to have for negative pressure caused by negative pressure device to protect patient internal and tissue in actual use
Pressure requirements, adult's generation pressure size is controlled in 0.04 ~ 0.05Mpa in suction sputum, pressure size control is produced to children
Make in 0.01 ~ 0.03Mpa, adult's generation pressure size is controlled in 0.03 ~ 0.04Mpa in gastric lavage, pressure is produced to children
Size is controlled in 0.01 ~ 0.02Mpa, and existing gastric lavage sputum aspirator does not have the function of adjusting pressure, and place one's entire reliance upon doctor
Experience, for some, just doctors for entering a profession or nurse lack practice in negative pressure control, therefore in the operation of gastric lavage sputum aspirator
There are gap in effect, or because worrying that patient's operation is irresolute, or because hypotony produces injury to patient, so as to influence urgency
Rescue effect.
The content of the invention
In view of the deficiencies of the prior art, the present invention intends to provide one kind pressure size change control can exist
The piston pressure-controlled type gastric lavage sputum aspirator of zone of reasonableness.
To achieve the above object, the present invention provides following technical solution：Including liquid pipe, liquid pipe one end is stretched as absorption edge
