Description

Sputum aspirator with pressure limit value control function
Technical field
The present invention relates to a kind of sputum aspirator, and in particular to a kind of sputum aspirator with pressure limit value control function.
Background technology
On-the-spot rescue outside hospital（Given first aid to outside abbreviation institute）Or in hospitalization, often occur that sputum etc. blocks air flue Cause patient respiration difficult or even the situation of asphyxia occur, often give patient using sputum aspirator and give effective emergency processing, So as to alleviate the pain of patient.
Traditional sputum aspirator, liquid pipe one end stretch into the tracheae of patient as absorption edge, and the other end is provided with as operating side Negative pressure device, the also usual unicom of liquid pipe are provided with sump assemblies and are used to recycle sputum, waste reflux are avoided to negative pressure device, in reality There are pressure requirements on border in use, in order to protect patient internal and tissue for negative pressure caused by negative pressure device, Vacuum magnitude control is produced during suction sputum to adult in 0.04 ~ 0.05Mpa, children are produced vacuum magnitude control 0.01 ~ 0.03Mpa, existing gastric lavage sputum aspirator do not have the function of control pressure, the experience for the doctor that places one's entire reliance upon, for some The doctor or nurse just to enter a profession lacks practice in negative pressure control, therefore there are gap on the operating effect of gastric lavage sputum aspirator, Injury easily is produced to patient because inside and outside differential pressure is excessive, so as to influence therapeutic effect.
The content of the invention
In view of the deficiencies of the prior art, the present invention intends to provide one kind avoid inside and outside differential pressure excessive and to suffer from Person produces the sputum aspirator with pressure limit value control function of injury.
To achieve the above object, the present invention provides following technical solution：Including liquid pipe, described liquid pipe one end is as suction Receiving end stretches into the tracheae of patient, and the other end is provided with negative pressure device as operating side, it is characterised in that：The liquid pipe is provided with Pressure regulating part and rotation selector, the pressure regulating part include several pressure controling holes being circumferentially arranged along liquid pipe, The pressure differential that is covered each by bearing in each pressure controling hole it is different destroy film, the rotation selector Annularly and liquid pipe periphery is rotatably dispose in, the rotation selector closes each pressure controling hole, rotation selection Portion offers the selecting hole by one of pressure controling hole and extraneous unicom.
By using above-mentioned technical proposal, according to different crowd and actual state, rotary motion selector adjusts selecting hole It is opposite with one of pressure controling hole, make the pressure controling hole and extraneous unicom, and destroying in the pressure controling hole is thin The pressure differential that film can bear is the pressure limit value that the sputum aspirator can be born, and is incited somebody to action when more than the pressure limit value sputum aspirator Function is lost, so as to be protected to organ, that is, tissue inside patient.
The present invention is further arranged to：The negative pressure device includes negative pressure cylinder, piston and piston rod, the piston rod Piston sliding is driven to detach the gas in liquid pipe to negative pressure when the piston is to away from the movement of liquid pipe direction in negative pressure cylinder In cylinder, the joining place of the negative pressure cylinder and liquid pipe is provided with the one-way flow mouth for only allowing air-flow to enter negative pressure cylinder from liquid pipe, The piston outer periphery is coated with sealed silicone.
By using above-mentioned technical proposal, piston rod driving piston sliding makes liquid pipe produce negative pressure in negative pressure cylinder, is driving Piston sliding sets one-way flow mouth in negative pressure cylinder, steady air current is entered negative pressure cylinder from liquid pipe, avoids gas backstreaming from causing to press Power is unstable, influences the steady operation of sputum aspirator, also avoids causing secondary injury to patient.
The present invention is further arranged to：The unidirectional discharge for only allowing air-flow outwardly to discharge is provided with the negative pressure cylinder Mouthful, it is provided with the return unit for resetting piston to liquid pipe between the piston and negative pressure cylinder.
By using above-mentioned technical proposal, when user does not exert a force, piston is subjected to return, negative pressure cylinder by return unit Interior remaining gas is discharged at unidirectional floss hole, easy to store or carry out negative pressure step next time, improves simple operation Property.
The present invention is further arranged to：Unicom is provided with waste discharge pipeline below the liquid pipe, the waste discharge pipeline with The other end of liquid pipe unicom is provided with mounting base, and the mounting base is detachably provided with the collecting means for collecting sputum.
By using above-mentioned technical proposal, collecting means are added, sputum is collected, avoid sputum from entering negative pressure device, The normal work of negative pressure device is influenced, mounting base is added, different types of collecting means can be installed according to demand, or in a certain collection Part can not timely quick-replaceable after use, ensure long-term, the work stablized of sputum aspirator.
The present invention is further arranged to：The collecting means are disposable phlegm bag, and the disposable phlegm bag lies in installation Seat.
By using above-mentioned technical proposal, as a kind of embodiment of collecting means, the form of disposable phlegm bag can carry out Compression, and there is the characteristics of easy to carry, light weight, therefore it is adapted to the medical environment of unfixed point, i.e. field, scene of the accident etc., drop It is low to carry burden caused by it, the wholesomeness used is improved, avoids cross-infection, the material of disposable phlegm bag can be selected and can drop Plastics are solved, reduces because of pollution caused by discarding, due to the characteristic that its is unsetting and unfixed point uses, therefore uses the installation fastened Mode, improves the convenience of installation.
The present invention is further arranged to：The collecting means are phlegm tank, and the phlegm tank is provided with matches somebody with somebody with mounting base screw thread The opening of conjunction, phlegm tank outside are provided with volume scale.
By using above-mentioned technical proposal, as a kind of embodiment of collecting means, phlegm tank can keep fixed shape, And there is cleaning, Reusability repeatedly, therefore it is adapted to the medical environment with cleaning condition, i.e. hospital, clinic, medical station Deng, reduce use cost, reduce because abandoning collecting means institutes pollution on the environment, the spy used due to its setting and fixed point Property, therefore the mounting means of thread fitting is used, the stability of installation is improved, the volume scale added is easy to the patient understood in time Situation.
The present invention is further arranged to：The liquid pipe is located at absorption edge and is provided with pipe joint, the pipe joint it is interior Wall, which is provided with, guides sputum to the guide surface of collecting means.
By using above-mentioned technical proposal, guide surface is added, sputum flow direction is guided, can quick and precisely be arrived Up to collecting means, the collection efficiency of collecting means is improved, that is, ensures that liquid pipe is unimpeded, accelerates suction sputum efficiency.
The invention will be further described with reference to the accompanying drawings and detailed description.
