At present, a contrast agent is manually pushed by a 20ml syringe by a contrast doctor mainly by the aid of the contrast agent, the pressure in a uterine cavity is changed due to inconstant hand force, complications can also be caused, and meanwhile, the radiation dose borne by the contrast doctor is increased. The existing drainage bag only has a trapezoidal variable-pipe-diameter interface and can only be connected with a horn-shaped interface of a catheter. The drainage ends of the existing external fistulation tubes such as kidney fistulation tubes, gall bladder fistulation tubes and the like are threaded connectors, and the drainage tubes are connected when being connected with the drainage bag, so that the connection times are increased, the connection of the drainage tubes with the trapezoidal variable tube diameter with the drainage bag is easy to drop, and the infection risk is increased. At present, a 20ml syringe is adopted for injecting the medicine into the three-cavity catheter flushing cavity or the single-cavity catheter drainage cavity in the bladder, the medicine needs to be sucked for multiple times in the operation, and the infection risk is increased. To this end, we propose a single-use interventional injection and drainage device.
SUMMERY OF THE UTILITY MODEL
The present invention is directed to a disposable injection and drainage device for interventional use, which solves the above-mentioned problems of the prior art.
In order to achieve the purpose, the utility model provides the following technical scheme: a disposable injection and drainage device for intervention comprises an injection connecting pipe and an insertion column pipe, wherein the left end of the injection connecting pipe is connected with a stepped variable-pipe-diameter interface, and the right end of the injection connecting pipe is connected with a butterfly wing threaded interface;
the left end of the inserting column tube is inserted with a hollow inserting column, the right end of the inserting column tube is connected with a drainage bag which is integrally formed with the inserting column tube, the hollow inserting column is sleeved with a rotating handle and a nut, the hollow inserting column is inserted into the butterfly wing threaded interface, and the nut is screwed on the outer side of the butterfly wing threaded interface.
And the injection connecting pipe and the inserting column pipe are respectively provided with a clip. Therefore, the flowing speed of the liquid medicine in the injection connecting pipe and the inserting column pipe can be adjusted by the clips.
The hollow splicing column is sleeved with a rubber pad positioned in the nut, and the rubber pad seals the butterfly wing threaded interface after the nut is locked. Therefore, the tightness of the butterfly wing threaded interface and the hollow insertion column after connection can be improved.
Compared with the prior art, the utility model has the beneficial effects that: the utility model changes the contrast agent injection by hand into the contrast agent pumping by the injection pump, thereby improving the efficiency, reducing the technical difficulty and reducing the radiation dose borne by a contrast doctor. The drainage bag is connected with an extracorporeal fistulation tube (namely an injection connecting tube) through the hollow splicing column and then fixed by the nut, so that secondary connection is avoided, the working efficiency is improved, the risk of separation is avoided, and the infection risk is reduced.
Meanwhile, the injection connecting pipe is connected with the plug-in column pipe and the drainage bag, and then the function of the drainage bag with the stepped variable-pipe-diameter interface can be realized. The existing partial drainage device is integrated, and the clinical practical situation is better met. This disposable intervenes with injection and drainage device, with low costs, convenient to popularize and apply.
