Abstract

The utility model relates to a medical instrument, in particular to a device for switching between oral cavity and nasal cavity of nasobiliary tube. The device mainly comprises an oral and nasal catheter and a traction catheter; the device is characterized in that magnet pieces are respectively and additionally arranged at the head ends of the oral and nasal catheter and the traction catheter; the oral and nasal catheter with the magnet piece additionally arranged at the head end is inserted into the oropharyngeal part through the nose, and then the traction catheter with the magnet piece additionally arranged at the head end is inserted into the oropharyngeal part through the mouth; according to the principle of attraction of the magnet, the head ends of the oral and nasal catheter and the traction catheter are butted together at the oropharyngeal parts under the attraction action, the traction catheter is held in one hand and pulled out of the oral and nasal catheter inserted in through the nasal cavity, the oral and nasal catheter is transported through the other hand until the oral and nasal catheter is pulled out of the oral cavity, the butted head ends of the oral and nasal catheter and the traction catheter are separated, the oral and nasal catheter is intruded into the nasobiliary catheter through a guide hole at the head end of the oral and nasal catheter, then the oral and nasal catheter is removed, and the transformation work for the ENBD oral and nasal catheter is further finished; and the phenomenon that the oral and nasal catheter is hurt or the pharyngeal tissue is stimulated since the oral and nasal catheter is clamped or snared out from the oral cavity before is avoided.

Description

Nose bile duct mouth and nose chamber conversion equipment

Technical field

This utility model belongs to medical apparatus and instruments, particularly a kind of nose bile duct mouth and nose chamber conversion equipment.

Background technology

Through scope nasobiliary drainage (Eadoscopic Nasolbiliary Draiuage ENBD) is one of treatment bladder series disease method.Duodenoscope is after nose bile duct is inserted in the oral cavity, and nose bile duct is more by the method that the oral cavity imports nasal cavity.Insert the mouth and nose conduit to posterior wall of oropharynx as more often using via intranasal application now, press from both sides out the mouth and nose conduit through the oral cavity with sponge holding forceps.Existing problems are people's lateral positions due to illness, and ccavum oropharygeum appears not exclusively, and it is accurate that clamp is difficult to once, often causes patient's bottleneck throat significant discomfort, have increased pincers and have got mouth and nose conduit difficulty, the easier pharyngeal that crushes.Also have the crooked seal wire of application to support to swallowing rear wall, via intranasal application is inserted the mouth and nose conduit to pars oralis pharyngis, and tractive goes out the mouth and nose conduit, finishes the work that the nose bile duct oral cavity is converted to nasal cavity, and also there is pharyngeal irritant reaction in the method.Therefore, how to make the mouth and nose chamber conversion operations of ENBD easy, misery alleviates, and becomes the focus that the scope doctor pays close attention to.

The utility model content

The technical problem that this utility model solves is to overcome the deficiency in the prior art, and a kind of nose bile duct mouth and nose chamber conversion equipment is provided, and makes the mouth and nose chamber conversion operations of ENBD easier, and patient's misery alleviates.

For realizing the purpose of utility model, the technical scheme of employing is that a kind of nose bile duct mouth and nose chamber conversion equipment mainly is made up of mouth and nose conduit, traction conduit, it is characterized in that: mouth and nose conduit and traction conduit head end install the cylindrical magnet piece additional.

Beneficial effect is that this conversion equipment utilizes the attraction principle, make via intranasal application insert the mouth and nose conduit that head end installs magnet piece additional, the traction conduit that is installed additional magnet piece by head end inserts through the oral cavity, attract butt joint in pars oralis pharyngis, make the mouth and nose conduit be pulled conduit tractive outlet plenum, form the catheter channel in nasal cavity and oral cavity.Needing to have avoided going out the mouth and nose conduit from oral cavity clamp or snare in the past, and crushing of occurring or stimulate pharyngeal.

The specific embodiment

With the specific embodiment this utility model is described in further detail in conjunction with the accompanying drawings.

Nose bile duct mouth and nose chamber conversion equipment is made up of mouth and nose conduit 1, traction conduit 2, and head end installs magnet piece 3 additional.Hold mouth and nose conduit 1 per nasal that head end installs magnet piece additional and be inserted into pars oralis pharyngis, per os inserts head end and installs the traction conduit 2 of magnet piece additional to pars oralis pharyngis again.According to the magnet piece attraction principle, mouth and nose conduit head end and traction conduit head end attract butt joint together in pars oralis pharyngis, hand-held traction conduit 2 slow tractives go out the mouth and nose conduit 1 that via intranasal application is inserted, the another hands is slowly carried mouth and nose conduit 1, be pulled outside the outlet plenum until mouth and nose conduit 1, separate the head end 3 that traction conduit 2 and mouth and nose conduit 1 attract butt joint, import nose bile duct through mouth and nose conductor housing end entrance hole 4, slowly remove the mouth and nose conduit subsequently, finish ENBD oral and nasal cavity vessel conversion work.

The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
