Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of electric pole type suction aspirator tip.
Background technology
Suction pump is existing a kind of medical apparatus and instruments for drain, is common in surgical field.At present, suction pump is broadly divided into single-body type suction pump and middle controlled suction pump.Wherein, single-body type suction pump volume is little, carry flexible, is common in middle and small hospital, field medical and battlefield medical treatment; Middle controlled suction pump is then utilize a large-scale vacuum suction equipment outwards to branch out several suction catheters as total vacuum suction source, simultaneously for multiple suction pump provides vacuum suction source, the benefit of this mode is attraction powerful, easy to use, can perform the operation for multiple stage provides powerful vacuum suction source simultaneously, be widely used in larger hospital.
The object of suction pump is in order to drain, is one of requisite operating theater instruments in existing surgical procedures.Carrying out in abdominal cavity cleaning work, medical personnel need hydrops, hematocele or the flushing water of hand-held suction pump in the absorption abdominal cavity, position that needs are removed, but abdominal cavity is all bending under normal circumstances and has fold, in the hydrops of fold part, hematocele or the bad cleaning of flushing water, this just needs to intraperitoneal inflatable body, and pneumoperitoneum makes formation working place, abdominal cavity.But current suction aspirator tip cannot optionally attract, thus in use, the medical worker lacked experience is usually due to misoperation, after absorption one place hydrops, do not close suction pump in time and the gas be full of in abdominal cavity is siphoned away by mistake, thus cause abdominal cavity air pressure not enough and become shrivelled, lose the working place of operation, therefore have to abdominal cavity repeated inflation, just extend operating time like this, add the difficulty of operation.Secondly, when carrying out cleaning operation, owing to not closing the mucosa that suction pump is also easily drawn onto internal abdominal wall in time, cause tissue injury.
Utility model content
Goal of the invention of the present utility model is: the technical problem solving above-mentioned existence, provides a kind of electric pole type suction aspirator tip, its can according to the situation of reality automatically control suction pump break-make, practicality is safe, easy to use, structure is simple.
The technical solution of the utility model is as follows: a kind of electric pole type suction aspirator tip, it is characterized in that: comprise the aspirator tube be connected with vacuum suction source, be arranged in aspirator tube tube chamber for controlling the valve closed between vacuum suction source and aspirator tube tube chamber or be communicated with, the driving device for driver's valve door trip be connected with valve and be connected the power supply circuits of powering with driving device, described power supply circuits comprise for providing the power input port of power supply to circuit and being used for the pair of electrodes switch of control circuit break-make, described pair of electrodes switch is separately positioned on two relative positions of aspirator tube leading section internal face, described pair of electrodes switch to enter in aspirator tube tube chamber at liquid and submergence two electrode switch time connect power supply circuits, otherwise disconnection power supply circuits.
Its operation principle and work process are:
In the middle of the operation of pneumoperitoneum, during use, suction aspirator tip is extend into the intraperitoneal being full of non-conductive gas, when the aspirator tube being provided with electrode switch touches gas, non-conductive due to gas, therefore two electrode switch are not switched on, and now valve is in closure state thus blocks the entrance in vacuum suction source; Touch liquid once two electrodes simultaneously, electrode switch is switched at once, valve open makes aspirator tube be communicated with vacuum suction source, suction pump is started working, by external for Intraabdominal liquid sucking-off, after the liquid at this place is blotted, owing to losing conductive medium, operating circuit is disconnected again between two electrodes, valve closing, suction pump quit work immediately.When two electrodes touch the residual liquid of intraperitoneal again, suction pump is started working once more, circulates and so forth, and the alveolar fluid clearance the most at last in body is clean.
At least there are following two kinds of optimal enforcement schemes in described power supply device:
Scheme one: described power input port is movable power source.
Like this, can be easy to carry, after adopting disposable movable power source during manufacture, this suction pump can also be guaranteed
Property uses, avoids being utilized by people's secondary causing cross infection for the first time.
Scheme two: described power input port is the power input port that can be communicated with external power source.
This scheme manufacturing cost is relatively low, garbage not easily contaminated environment simultaneously.
In order to implement this utility model better, additionally provide following prioritization scheme:
Further, also potential device is provided with between described electrode switch and power supplier.
When the input electric energy of needs outside time, because used external voltage is all higher than the safe voltage of 36V, is generally 220V, thus needs the safe voltage that potential device will allow in voltage transitions adult body.
Further, the protection circuit preventing power supplier short circuit is also provided with between described electrode switch and power supplier.
Owing to being carry out livewire work at inside of human body; thus under needing strictly to protect the voltage guaranteeing used circuit to be in human safety voltage all the time to used circuit, simultaneously owing to adopting the mode of electrode conduction as switch, such protection circuit is adopted effectively to avoid electrode to be short-circuited.
When the power supply using alternating current as electrode switch, owing to considering safety issue, in the middle of power supply and electrode switch, be provided with potential device and protection circuit.
Further, described electrode switch and suction aspirator tip are 5-10mm towards the distance of the termination of tissue fluid one end.
Preferably, described electrode switch and suction aspirator tip are 8mm towards the distance of the termination of tissue fluid one end.
Due to the good conductor that the tissue of human body or organ are also electricity, such setting just avoid electrode switch and histoorgan directly contact there is conducting after error starting suction aspirator tip and attract the mucosa of tissue or organ, thus prevent the damage causing histoorgan.
The beneficial effects of the utility model are: suction pump of the present utility model is provided with the electrode switch being used to open or close aspirator tube valve, can according to whether there is liquid and the duty of the suction pump that automatically switches, realize the object of not discharging Intraabdominal gas and only drain, avoid and inhale Intraabdominal gas because medical worker operates unskilled mistake, and repeated inflation operation is carried out to abdominal cavity, decrease the duplication of labour thus accelerate procedure, reducing misery and the inconvenience of patient and medical personnel.In abdominal, abdominal cavity mucosa can not be drawn onto due to maloperation.Even if be not that very skilled medical personnel utilize suction pump to carry out work, also can finish the work very simply.Effectively ensure that after disposable power supply is set that the disposable of suction aspirator tip prevents secondary use and cause the risk of cross infection.
