Description

Auxiliary assembly for leading ENBD tube out of nasal cavity

Technical Field

The utility model relates to a medical treatment auxiliary assembly technical field particularly, indicates an auxiliary assembly that is used for drawing ENBD pipe from the nasal cavity.

Background

Endoscopic nasobiliary drainage (ENBD) is an endoscopic treatment method in which a nasobiliary tube (namely an ENBD tube) is placed in a proper position of the bile duct through a duodenoscope and is finally led out from a nasal cavity on one side of a patient, so that bile above a bile duct blockage position or a lesion position is drained to the outside of a body.

However, the ENBD tube firstly passes through the oral cavity from the outside of the oral cavity to enter the human body, and after the ENBD tube is placed at a proper position of the bile duct, if the ENBD tube is directly placed in the mouth of a patient, normal speaking and eating of the patient are affected, and the patient may bite the ENBD tube.

In the prior art, a catheter is inserted into the nasal cavity of a patient, and then enters the oral cavity, and the catheter is clamped by tweezers and pulled out of the oral cavity. At this time, both ends of the catheter are respectively positioned outside the nasal cavity and the oral cavity, and a channel is established between the nasal cavity and the oral cavity. And then the end of the ENBD tube remained outside the oral cavity of the patient extends into the end of the catheter positioned in the oral cavity and extends all the way to the inside, the end of the ENBD tube finally extends out from the end of the catheter positioned in the nasal cavity along the catheter, and finally the catheter is drawn out from the nasal cavity, so that the purpose that the ENBD tube extends out of the nasal cavity of the patient can be realized.

However, in the process of using forceps to clamp the catheter out of the oral cavity, the interior of the oral cavity of the patient is easily accidentally injured, the operation is inconvenient, and the oral cavity of the patient is injured.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims at overcoming the not enough of prior art, provide an auxiliary assembly for inciting somebody to action ENBD pipe is drawn forth from the nasal cavity to solve prior art and use tweezers to press from both sides the in-process of pipe from the oral cavity in, easily with the inside accidental injury in patient's oral cavity, operate inconvenient moreover, have the technical problem who makes the risk of patient's oral cavity damage.

The utility model provides a technical scheme that its technical problem adopted is:

the auxiliary assembly for leading the ENBD tube out of the nasal cavity comprises a flexible auxiliary tube which can sequentially penetrate through the nasal cavity and the oral cavity, wherein the interior of the flexible auxiliary tube is hollow, two ends of the flexible auxiliary tube are opened, and the inner diameter of the flexible auxiliary tube is larger than the outer diameter of the ENBD tube;
