Description
Technical field
This utility model relates to the technical field of armarium, refers more particularly to a kind of puncture outfit for cardiothoracic surgery.
Background technology
At present, the liquid extracting device that the treatment of cardiothoracic surgery puncture uses, its structure is that the front end sleeve of syringe has piercing needle, when the liquid extracted is less, can once complete, when the liquid extracted is more, necessary repeated multiple times extraction, must pull out syringe each time, pour out liquid in pipe, and then be connected with piercing needle, add the labor intensity of medical worker.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of puncture outfit for cardiothoracic surgery.
This utility model is realized by above technical scheme:
This utility model provides a kind of puncture outfit for cardiothoracic surgery, this puncture outfit for cardiothoracic surgery comprises: needle tubing, the communicating pipe be communicated with the cavity of described needle tubing, described communicating pipe is connected with reservoir, and described communicating pipe is provided with the first check valve, described reservoir is connected with flexible suction capsule, and be provided with the second check valve between described flexible suction capsule and described reservoir, described suction air is provided with gas outlet, described gas outlet is provided with the 3rd check valve, wherein, the conducting direction of described first check valve is that described cavity is to described reservoir, the conducting direction of described second check valve is that described reservoir is to described suction air, the conducting direction of described 3rd check valve is that described suction air is outside to suction air.
Preferably, the junction of described communicating pipe and described reservoir is positioned at the bottom of described reservoir, and the junction of described suction air and described reservoir is positioned at the top of described reservoir.
Preferably, described suction air is also provided with liquid outlet, dismountablely on described liquid outlet is provided with sealing-plug.
The beneficial effects of the utility model are: can increase the volume of the liquid of absorption by the suction air that arranges and reservoir, avoid repeatedly needle tubing to be inserted into the ambition of human body inner, alleviate the misery of patient.
Accompanying drawing explanation
Fig. 1 is the structural representation of the puncture outfit for cardiothoracic surgery that this utility model embodiment provides.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain this utility model, and be not used in restriction this utility model.
Refer to Fig. 1, Fig. 1 is the structural representation of the puncture outfit for cardiothoracic surgery that this utility model provides.
This utility model embodiment provides a kind of puncture outfit for cardiothoracic surgery, this puncture outfit for cardiothoracic surgery comprises: this utility model provides a kind of puncture outfit for cardiothoracic surgery, this puncture outfit for cardiothoracic surgery comprises: needle tubing 10, the communicating pipe 20 be communicated with the cavity of described needle tubing 10, described communicating pipe 20 is connected with reservoir 30, and described communicating pipe 20 is provided with the first check valve 21, described reservoir 30 is connected with flexible suction capsule 40, and be provided with the second check valve 43 between described flexible suction capsule 40 and described reservoir 30, described suction air 40 is provided with gas outlet 41, described gas outlet 41 is provided with the 3rd check valve 42, wherein, the conducting direction of described first check valve 21 is that described cavity is to described reservoir 30, the conducting direction of described second check valve 43 is that described reservoir 30 is to described suction air 40, the conducting direction of described 3rd check valve 42 is that described suction air 40 is outside to suction air 40.
In the above-described embodiments, by adopting said structure, when drawing a small amount of liquid, directly drawn by needle tubing 10, when the liquid drawn is more, when single needle tubing 10 cannot directly have been drawn, can, by pressing suction air 40, the air pressure in reservoir 30 be reduced, thus continue imbitition by communicating pipe 20, thus realize the absorption that can complete the intrathoracic liquid of the heart after needle tubing 10 is once drawn, avoid the repeatedly insertion of needle tubing 10, reduce the misery of patient.In the above-described embodiments, achieve the control to air pressure and flow direction by the multiple check valves adopted, ensure that the liquid entered in reservoir 30 there will not be refluence, meanwhile, the suction air 40 set up adds speed and the efficiency of imbitition.
Preferably, described communicating pipe 20 and the junction of described reservoir 30 are positioned at the bottom of described reservoir 30, and described suction air 40 and the junction of described reservoir 30 are positioned at the top of described reservoir 30.Thus avoid sucking liquid in suction air 40.
Preferably, described suction air 40 is also provided with liquid outlet 31, dismountablely on described liquid outlet 31 is provided with sealing-plug.After using, can directly from liquid outlet 31, liquid be released.
Can be found out by foregoing description, the puncture outfit for cardiothoracic surgery that the present embodiment provides can increase the volume of the liquid of absorption by the suction air 40 that arranges and reservoir 30, avoids repeatedly needle tubing 10 to be inserted into the ambition of human body inner, alleviates the misery of patient.
These are only preferred embodiment of the present utility model, not in order to limit this utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
