Description
Technical field
This utility model relates to technical field of surgical instruments, is specifically related to a kind of Novel suction unit connecting duct.
Background technology
Suction pump is the content for absorbing in hands intraoperative hemorrhage, exudate, pus, thoracic organ, makes operation clear, decreasing pollution chance.The principle of suction pump is exactly the negative pressure state being manufactured its sucking head by certain method, and the material outside sucking head will extrude to sucking head by such atmospheric pressure, thus completes the effect of attraction.During suction apparatus attracts liquid, its end need connect Aspiratory catheter, and the other end of conduit connects negative-pressure suction bottle, and by the effect of negative pressure, abdominal cavity liquid can pass through suction aspirator tip inflow catheter, finally collects in negative-pressure suction bottle.
At present, in clinical operation, often can require that extracting part splanchnocoel liquid does corresponding detection.If the words of open surgery, medical personnel directly can give over to specimen with syringe extraction part hydrops and do corresponding detection, but if the words of peritoneoscope Minimally Invasive Surgery operation, medical personnel directly cannot draw hydrops, hydrops can only be sucked in drainage tube by vacuum extractor, penetrate in drainage tube with syringe and draw hydrops, specimen taken.If doing so, one is inconvenient operation, and two is that the liquid sucked in drainage tube can flow under the effect of vacuum suction, and lose control of direction a little when sometimes aspirating with syringe, hydrops will be run away, and cannot complete the object leaving and taking the capable detection of hydrops.
Utility model content
The purpose of this utility model is exactly at present, in clinical operation, often can require that extracting part splanchnocoel liquid does corresponding detection.If the words of open surgery, medical personnel directly can give over to specimen with syringe extraction part hydrops and do corresponding detection, but if the words of peritoneoscope Minimally Invasive Surgery operation, medical personnel directly cannot draw hydrops, hydrops can only be sucked in drainage tube by vacuum extractor, penetrate in drainage tube with syringe and draw hydrops, specimen taken.If doing so, one is inconvenient operation, two is that the liquid sucked in drainage tube can flow under the effect of vacuum suction, direction is lost control of a little when sometimes aspirating with syringe, hydrops will be run away, the deficiency of the object leaving and taking the capable detection of hydrops cannot be completed, and a kind of Novel suction unit connecting duct is provided.
This utility model comprises sucking head, A connection tube, B connection tube, hydrops bottle and negative pressure generator, one end of A connection tube communicates with sucking head, the inlet of hydrops bottle communicates with one end of B connection tube, the air entry of negative pressure generator communicates with the bleeding point of hydrops bottle, it is characterized in that it also has sample collecting apparatus, sample collecting apparatus comprises connecting tee, A valve, snap joint female joint, the sub-joint of snap joint and puncture needle, wherein two interfaces of connecting tee are connected between A connection tube and B connection tube, the entrance of A valve communicates with another interface of threeway, snap joint female joint is arranged on the exit of A valve, the sub-joint of snap joint communicates with snap joint female joint, and the sub-jiont treatment of snap joint is at the liquid pumping hole place of puncture needle.
Also have B valve, A connection tube is communicated by one of them interface of B valve and connecting tee.
Also have C valve, one of them interface of connecting tee is communicated with B connection tube by C valve.
Connecting tee is that 316L sanitation-grade stainless steel is made.
This utility model has the following advantages: popularization of the present utility model, and can provide a kind of Novel suction unit connecting duct that conveniently can carry out operation hydrops specimen draw, structural design advantages of simple, simple operation, has good market popularization value.
Accompanying drawing explanation
