Abstract

An oronasal catheter converter relates to the technical field of medical appliances, in particular to a medical appliance which is used for guiding a nasal catheter out of an oral cavity in a naso-biliary drainage, and comprises a guide wire, a bushing, a fixed handle and a movable handle, wherein the fixed handle is connected with the tail end of the bushing; the movable handle is provided with asleeve which is movably sleeved on the bushing; a longitudinal notch is arranged on the side wall of the bushing; and the guide wire is a snare-shaped cord, the two ends of which are folded in half;the cord part of the cord is positioned in the bushing, the cord ends are connected with the movable handle after passing through the notch, and the ring part of the cord is positioned at the front end of the bushing. The utility model has the advantages that the oronasal catheter converter can conveniently guide the nasal catheter out of the oral cavity, thereby avoiding that the finger of an operator is bitten during the operation, and a patient has strong nausea reaction, bucking, lowed oxygen saturation, aspiration pneumonia caused by swallow by mistake and damage to the mucous membrane ofnasal pharynx, and secondary infection.

Description

Mouth and nose conduit transducer

Technical field

This utility model relates to technical field of medical instruments, refers more particularly to the medical apparatus and instruments aspect of mouth and nose conduit switch technology.

Background technology

Often relate to mouth and nose conduit switch technology in the digestive endoscopy treatment, need to insert placement during because of control digestive tract conduit with the scope per os, and fixing the reaching of conduit need be converted to per nasal digestive tract conduit when using, as nose bile drainage tube, the placement of nose jejunum drainage tube, the narrow nutritive canal placement of upper digestive tract etc.The patient needs to extend the patient with finger and swallows rear wall guiding tube is taken out of in traditional mouth and nose converter approach, because it is pharyngeal that the food middle finger stretches into the patient, stimulate the root of the tongue and pharynx rear wall, cause the intensive nauseating reaction of patient, even cause the patient to choke to cough, oxygen saturation descends, the mistake pharynx causing aspiration pneumonitis.Because some patient's obesity, the pharynx rear wall is dark, and patient's finger reaches the pharynx rear wall, the nose conduit is difficult to press from both sides out, because of using tranquilizer before the art, patient's consciousness is not clear fully as yet during guiding nose conduit, adds pharyngeal severe irritation again, make agitation, opposing, be difficult to fine cooperation, be difficult to take out of the nose conduit sometimes, repeatable operation can cause the nasopharynx part mucosa injury, secondary infection, even cause the patient to point and bitten.

Summary of the invention

In sum, the purpose of this utility model is to propose a kind of can easily digestive tract conduit per os being drawn to be converted to the mouth and nose conduit transducer that per nasal is drawn.

The technical solution of the utility model is: comprising: seal wire, sleeve pipe, fixed handle and flexible handle; Described fixed handle is connected telescopic tail end; Described flexible handle is provided with a sleeve, and sleeve is actively socketed on the sleeve pipe; Described sleeve pipe sidewall is provided with vertical breach; Described seal wire is the snare shape noose of two ends doubling, and the rope of noose is deployed in sleeve pipe, and fag end is connected with flexible handle through vertical breach, and the circle of noose is deployed in telescopic front end.

Described sleeve pipe mainly is formed by connecting by two-section different materials pipe, and tail end is a steel pipe, the front end plastic tube.

Described flexible handle comprises forefinger circle, middle finger circle and sleeve, and forefinger circle and middle finger circle are connected the sleeve both sides symmetrically.

Also be provided with union joint and latch between described seal wire two ends and flexible handle, the seal wire two ends are connected on the union joint, and union joint is provided with hole clipping, and latch laterally is connected with the flexible handle sleeve through telescopic vertical breach and hole clipping.

Described seal wire is the elasticity seal wire that contains steel core.

Described lasso portion diameter is 1～5cm.

Described outer wall of steel pipe is provided with latch; Described sleeve is provided with the grab that cooperates clamping with latch.

In addition, the diameter of the guiding sleeve that is adopted in the art is 16Fr (5.33mm), is about 45cm, the quality softness, and the surface has scale.

The beneficial effects of the utility model are: guiding sleeve partly stretches in the patient oral cavity, the circle portion of noose entangles after the guiding sleeve, flexible handle moves toward the sleeve pipe tail end, the circle portion of noose dwindles the pinning guiding sleeve, just can easily guiding sleeve be taken out of from the oral cavity, has avoided in the operating process patient's finger to be bitten, the intensive nauseating reaction of patient, choke cough, oxygen saturation descends, the mistake pharynx causing aspiration pneumonitis and nasopharynx part mucosa injury, secondary infection.

The specific embodiment

The utility model will be further described below in conjunction with the drawings and specific embodiments:

Shown in Fig. 1, in per os digestive tract drainage, first step: insert scope in the oral cavity after, place per os digestive tract drainage tube 2, withdraw from scope, insert guiding sleeve 1 from a side nostril, guiding sleeve 1 is made guiding tube.Guiding sleeve 1 is provided with scale, for insertion process provides reference, avoids inserting not in place and inserts and take an advanced study into patient's discomfort.

Second step: shown in Fig. 2, from the oral cavity, draw guiding sleeve 1, then per os digestive tract drainage tube 2 is inserted the end of guiding sleeve 1.

Third step: shown in Fig. 3, in nasal cavity, draw along guiding sleeve 1.

This utility model is mainly used in second step oral cavity in the guiding sleeve 1 is drawn.Concrete structure of the present utility model is with reference to Fig. 4 and Fig. 5.

Shown in Fig. 4 and Fig. 5, comprising: seal wire 3, sleeve pipe 4, fixed handle 5 and flexible handle 6; Described fixed handle 5 is connected the tail end of sleeve pipe 4, and during use, fixed handle 5 is enclosed within on the thumb.Described flexible handle 6 is provided with a sleeve 63, and sleeve 63 is actively socketed on the sleeve pipe 4, and flexible handle 6 also is provided with a forefinger circle 61, middle finger circle 62, wherein, forefinger circle 61 and middle finger circle 62 are connected in sleeve 63 both sides symmetrically, during use, are enclosed within respectively on forefinger and the middle finger.Described sleeve pipe 4 mainly is formed by connecting by two-section different materials pipe, tail end is a steel pipe 42, front end plastic tube 41, during use, the front end of sleeve pipe 4 need stretch in the oral cavity, front end adopts plastic tube 41 can avoid the oral cavity inwall that stabs under something unexpected happened, and the wherein symmetrical sidewall of steel pipe 42 is provided with vertical breach 421.Described seal wire 3 is the elasticity seal wire that a diameter 0.035cm contains steel core, become the noose of a snare shape after the seal wire 3 two ends doublings, the rope portion 32 of noose penetrates in the sleeve pipe 4 through sleeve pipe 4 front ends, fag end is connected on the union joint 33, union joint 33 is provided with hole clipping 331, union joint 33 places sleeve pipe 4 inner chambers of vertical breach 421 correspondences, is provided with pin-and-hole 631 on sleeve 63, is provided with a latch 632 in the pin-and-hole 631 and laterally interts in vertical breach 421 and hole clipping 331; The circle portion 31 of noose is circle or ellipse circle that the minor axis diameter is 1～5cm that a diameter is 1～5cm, and the circle portion 31 of noose places the front end of sleeve pipe 4.
