Description

A kind of device for the conversion of nose bile duct mouth and nose

Technical field

The utility model is related to a kind of devices for the conversion of nose bile duct mouth and nose.

Background technology

Patient usually requires piece nose bile duct continuation bile drainage of indwelling and remaining contrast agent in biliary tract after ERCP stone-extraction operations, Nurse needs to be transformed into nasal cavity the nose bile duct being placed in through scope in oral cavity by a kind of method.But since ERCP operations are complete Process patient is calm using intravenous injection diazepam, and ERCP is operated under small number of patients selection general anesthesia, thus patient exists Consciousness patient's state of consciousness that is not awake enough or even having obscures when nose bile duct mouth and nose are converted, and irritation is operated and is resisted, operation The probability that person is bitten can greatly increase.

At present, the method for mouth and nose conversion nose bile duct has method after conventional method and improvement.Traditional will be drawn with hand or long forceps The method that the apex of flow tube is pulled out from oral cavity generates larger stimulation to the bottleneck throat of patient, and patient is allowed nausea and vomiting occur Situation.Group (being made of the discarded seal wire one and nose conduit that are about 45cm or so) is extracted after improvement with seal wire to be converted, Seal wire curves ellipse and is inserted into oral cavity until touching pharynx rear wall, it is made to fully take up pharyngeal chamber by the natural resiliency of seal wire Road, then a nose conduit is inserted into about 20cm from side nostril, nose conduit has been fallen into " snare " of seal wire at this time, is pulled outwardly and is led Silk takes nose bile duct out of, finally draws nose bile drainage tube under the guiding of nose conduit, fixed.Method is compared with conventional method after improvement Reduce the operating time and operator bites rate, at present using more.But since seal wire is thin, poor controllability, it is still necessary to operate The hand handle seal wire of person curves the radian of needs and puts in patient oral cavity and fixes, and the chance that operator bites still has；And it leads Silk hardness is high, and the patient feels are uncomfortable, if one end flicks the risk for scratching patient's mucous membrane of mouth.

In view of the above shortcomings, the designer, is actively subject to research and innovation, it is a kind of for nose bile duct mouth and nose to found The device of conversion makes it with more the utility value in industry.

Utility model content

In order to solve the above technical problems, the purpose of this utility model is to provide a kind of dress for the conversion of nose bile duct mouth and nose Put, which effectively shortens the time of mouth and nose conversion nose bile duct, ensures the comfort level of operator's safety and patient, reduce patient by The probability of infection.

The device for the conversion of nose bile duct mouth and nose of the utility model, Handheld Division including lengthwise and by taking over and one End connection, the oval lantern ring for entangling nose conduit, the Handheld Division other end are equipped with link.

Further, the Handheld Division is spirally connected with described take over.

Further, the link is enclosed by plastic hollow pipe.

Further, the Handheld Division is made of hollow plastic pipe.

Further, lantern ring hollow tube made of high molecular material encloses.

According to the above aspect of the present invention, the utility model has at least the following advantages：

1st, the device for the conversion of nose bile duct mouth and nose of the utility model can either effectively shorten mouth and nose conversion nose bile duct Time, and can guarantee operator's safety and the comfort level of patient, the hand of operator is maintained at outside patient oral cavity in operating process, drop The low infected probability of patient, Handheld Division person easy to operation hold, and hand is avoided to stretch into patient oral cavity, effectively reduce operator and are snapped The probability of wound；

2nd, the design of link is convenient for carrying and hangs；

3rd, Handheld Division, link and lantern ring are made of hollow tube, effectively reduce the weight of the device, easy to operation；

4th, Handheld Division, link material for plastic material, the material of lantern ring is high molecular material, increases the device and patient The compatibility of constitution, while further mitigate the weight of the device.

The above description is merely an outline of the technical solution of the present invention, in order to better understand the skill of the utility model Art means, and can be implemented in accordance with the contents of the specification, below on the preferred embodiment of the present invention and the accompanying drawings in detail It describes in detail bright as after.

Description of the drawings

Fig. 1 is the decomposition texture schematic diagram of the utility model device.

Specific embodiment

With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below Embodiment is used to illustrate the utility model, but be not intended to limit the scope of the present invention.

Referring to Fig. 1, a kind of device for the conversion of nose bile duct mouth and nose described in one preferred embodiment of the utility model, including It the Handheld Division 2 of lengthwise and is connect by take over 3 with one end, the oval lantern ring 4 for entangling nose conduit, the Handheld Division 2 The other end is equipped with link 1.Handheld Division 2 is length about 10cm, the smooth hollow plastic pipe of diameter about 0.5cm, person's hand easy to operation It holds, without stretching into patient oral cavity；Lantern ring 4 is the high molecular material hollow tube of ellipsoidal structure, and diameter is about 10-15cm；It is described For take over 3 with Handheld Division 2 by metal threaded connection, screw thread is about 3cm, passes through 3 fixation ellipse lantern ring 4 of take over；Link 1 is straight The plastic conduit of diameter about 2-3cm hollow designs, the device is hung convenient for operator in art.

When patient need to carry out the conversion of nose bile duct mouth and nose, operator holds Handheld Division 2, and patient is advised to be open and coordinate, and will cover Ring 4 is put into the pharynx rear wall in patient oral cavity, and the side nasal cavity that patient is stretched into the one end of nose conduit with side opening by another hand makes it It falls into this lantern ring 4；Handheld Division 2 is carried by nose conduit with outlet plenum, connects intraoral nose bile duct；Holding Handheld Division 2 again will cover Ring 4 stretches into oral cavity pharynx rear wall on the downside of nose bile duct and resists nose bile duct, stretches the mouth and nose of nose bile duct and then completion nose bile duct in nasal cavity Conversion, operator's hand is maintained at outside oral cavity in operating process.

The above is only the preferred embodiment of the utility model, is not intended to limit the utility model, it is noted that For those skilled in the art, it under the premise of the utility model technical principle is not departed from, can also do Go out several improvement and modification, these improvements and modifications also should be regarded as the scope of protection of the utility model.
