Abstract
The utility model relates to a medical instrument, in particular to a disposable leakage-proof and adjustable type negative pressure suction aspirator tip. The utility model aims to solve are that the prior suction aspirator tip is improved and the problems that the negative pressure suction aspirator tip leaks liquid and the rate of liquid aspiration can not be adjusted. The utility model is provided with a liquid guiding pipe and a liquid absorbing head is arranged at the front end of the liquid guiding pipe. The utility model is characterized in that the tip end of the liquid absorbing head takes a shape of a needle tube and an air hole communicated with the interior of the liquid absorbing head is arranged at the root part of the liquid absorbing head, and a sucker is further arranged at the root part of the liquid absorbing head. A regulating valve is further arranged at the rear end of the liquid guiding pipe. The tip end of the liquid absorbing head is very sharp, thus being convenient for the puncture operation of the doctor; moreover, the negative pressure is generated immediately in the sucker while the liquid absorbing head is inserted into the cyst cavity and the external wall of the cyst is caught up so as to realize the goal that the external leakage is not caused when the liquid in the cyst is absorbed. In addition, the rate of liquid aspiration can be regulated arbitrarily through the regulating valve when the liquid in the cyst is absorbed.
Description
Technical field
This utility model belongs to a kind of medical apparatus and instruments, particularly a kind of disposable leakproof adjustable negative-pressure suction aspirator tip that uses in abdominals such as abdominal surgery and department of obstetrics and gynecology.
Background technology
Vacuum extractor is extensive use in clinical practice, especially in abdominals such as abdominal surgery, department of obstetrics and gynecology, and indispensable especially apparatus.Vacuum extractor mainly is made up of two parts, and a part is the mechanical part that produces negative pressure, and another part is the suction aspirator tip of imbitition.At present, the suction aspirator tip of Ying Yonging clinically, no matter make of metal, still be to use plastic production, its structure is bushing type, promptly is made up of interior pipe, outer tube and union joint, interior pipe is positioned among the outer tube, union joint is installed in the rear end of interior pipe and outer tube, and is connected with stream guiding tube, and pod apertures is arranged on the front end of outer tube.Liquid enters into outer tube through pod apertures, and interior pipe of process and stream guiding tube enter into the receiver of vacuum extractor again.The problem that this suction aspirator tip exists is: 1, when carrying out the operation of abdominopelvic cavity giant cyst; especially to good, the pernicious cystic tumor of ovary; because the tumor body is huge, be difficult to whole taking-up the in abdominopelvic cavity, so; can only be with after the CF sucking-off; row takes out again, but owing to do not prevent the protective device that CF leaks outside on the existing suction aspirator tip, thereby; usually cause that CF leaks outside, therefore indivedual cases also cause the plantation of tumor or the diffusion of malignant tumor.2, do not have adjusting device, during in suction ascites, especially at the huge CF of suction, be difficult to control the speed of imbibition, in operation, often cause abdominal pressure to descend suddenly, cause blood pressure drops, when serious, also can cause the displacement of mediastinum internal organs because of imbibition is too fast.
Summary of the invention
The technical problems to be solved in the utility model is existing suction aspirator tip to be improved the problem that solution vacuum extractor head leakage and rate of liquid aspiration can not be adjusted.
This utility model has a catheter, at the front end of catheter the imbibition head is housed, and its special character is, the tip of imbibition head is sharp needle tubing shape, and the root of imbibition head has the pore that communicates with its inside, at the root of imbibition head a sucker is housed also.
Control valve also is equipped with in rear end at catheter, to regulate the speed of imbibition.
The tip of this utility model imbibition head is sharp needle tubing shape, be convenient to puncture procedure, the root of imbibition head is equipped with sucker, and the root of imbibition head also is provided with the pore that communicates with its inside, therefore, when the imbibition head thrusts the cyst intracavity, produce negative pressure in the sucker immediately, hold the outer wall of cyst, thereby realize inhaling the purpose that CF does not leak outside.
Control valve is equipped with in rear end at catheter, and when inhaling CF, the speed that can regulate imbibition by control valve is arbitrarily manipulated convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
The specific embodiment
As shown in drawings, this utility model has a catheter 4, at the front end of catheter 4 imbibition 1 is housed; The tip of imbibition 1 is sharp needle tubing shape, and the root of imbibition 1 has the pore 2 that communicates with its inside, at the root of imbibition 1 sucker 3 is housed also, and sucker 3 remains on negative pressure state when imbibition; Described imbibition 1 and catheter 4 are installed in the two ends of sucker 3 respectively, thereby both are coupled together; Control valve also is equipped with in rear end at catheter 4, and described control valve has a valve body 5, and spool 6 is housed on valve body 5, and handle 7 is housed on spool 6, moves handle 7 and can change the size that control valve is opened, and regulates the speed of imbibition; Also have a union joint 8 in the rear end of valve body 5, union joint 8 joins with the flexible pipe of vacuum extractor.
Claims (2)
1, a kind of disposable leakproof adjustable negative-pressure suction aspirator tip, it has a catheter, at the front end of catheter the imbibition head is housed, it is characterized in that, the tip of imbibition head is sharp needle tubing shape, and the root of imbibition head has the pore that communicates with its inside, at the root of imbibition head a sucker is housed also.
2, disposable leakproof adjustable negative-pressure suction aspirator tip according to claim 1 is characterized in that, in the rear end of catheter control valve is housed also.
