Description
Technical field
The application belongs to technical field of medical instruments, particularly a kind of disposable flexible suction aspirator tip.
Background technology
In surgical operation or operation on oral cavity, patient has hemorrhage.In order to draw these hematoceles to expose better surgical field of view, generally need with suction pump, blood to be siphoned away.
Suction pump conventional is clinically made up of interior pipe, outer tube and negative pressure union joint.Outer tube endcapped, has reticulated cell, and interior pipe, upper holder and negative pressure union joint are connected as a single entity.Outer tube is fixing on inner pipe by upper holder, irremovable.On outer tube, the position in hole, size can not change.Gap is had, the free-flow of tolerable liquid between outer tube and interior pipe.Liquid can enter gap between inner and outer pipes from the reticulated cell of outer tube, then enters interior tube chamber, and by negative pressure union joint, the negative pressure flowing to suction pump produces end.The advantage of this method is: allow that liquid flows into interior tube chamber, but tissue can not be inhaled into interior tube chamber.The shortcoming of this method is: mesh height is fixing, but liquid level is change.Along with liquid is sucked away, fluid level can decline.When part mesh exposes liquid level, interior pipe negative pressure can be caused to reduce, attract efficiency to decline.
Current invention design does not all solve this point very well.As CN01216062.8, while eliminating outer sleeve, also lose an imbibition, do not inhaled the advantage of tissue.And for example CN96208369.0, although add the means reconciling negative pressure, but still cannot solve with level change, reconcile the problem of pore.
Finally, above-mentioned design is the design of straight type, and cannot bend, holding end is at negative pressure connector position.When operative incision is very little, holding end is directly over operative incision.The hands being held in negative pressure connector position can block the visual field of patient, brings inconvenience.
