Abstract

The utility model relates to a white visualized lavage tube. The hardness and the diameter of lavage tube are matched with a gastroscope. The lavage tube and the gastroscope are connected into a whole, and are inserted into the esophagus at the same time. The utility model varies more than twice entries of the gastroscope into one entry, thereby reducing the injury and suffers of patients. Moreover, the utility model can realize that causes or bleeding sites can be found promptly and accurately under the rectangle of the endoscopic; thereby treatments also can be carried out promptly, thereby saving time for rescuing patients.

Description

The direct-view gastrolavage tube

This utility model belongs to a kind of clinical medicine apparatus, especially massive bleeding from upper digestive tract direct-view gastrolavage tube.

At present, the massive bleeding from upper digestive tract that occurs on the clinical medicine is a kind of commonly encountered diseases, and this disease morbidity is anxious, and the state of an illness is heavy, if handle the untimely dead danger that just has.Thereby, for the treatment of this disease, the problem that has become this field medical worker research for a long time and inquired into, though once studied some Therapeutic Method in succession, effect is all not good.Now, generally adopt urgent gastroscope Therapeutic Method both at home and abroad clinically, through clinical proof for many years, this method remains in certain weak point, mainly shows: 1. general massive bleeding from upper digestive tract patient, usually because the full hematocele of gastric is many, insert gastroscope and be difficult to determine bleeding part or cause of bleeding, directly influence the enforcement of treatment means, need appearance backlash gastric lavage microscopy again, need advance mirror among this for twice and operate step by step, bring misery to patient with the flushing stomach.2. owing to when flushing, be the blindness intubate, can cause blood crusts to come off and cause the danger of new damage.3. because the present gastrolavage tube that adopts is rubber tube, it is reddish brown or orange that color is, entering gastric is difficult to distinguish with coat of the stomach and blood, 4. because existing two kinds of gastrolavage tubes that use clinically, one class external diameter of pipe is thick, this pipe pipe rear end is thin soft, and its rear end is easy to subside when doing to attract, and makes to attract to interrupt, the outer surface of its two classes pipe is rough, manage promptly slightly firmly again, two class pipes all can not be connected with gastroscope and insert esophagus simultaneously, in addition, the gastrolavage tube function singleness, can not carry out other operations, especially latter's front end porous is difficult to control current and accurately washes.

The purpose of this utility model is exactly that research experiment design is a kind of repeatedly can be connected the gastrolavage tube that inserts esophagus simultaneously with gastroscope at above-mentioned not foot channel, thereby being implemented in scope directly looks down down, wash accurately and effectively, remove hematocele, in order to assigning a cause for an illness and the bleeding part, take therapy measure, improve salvage success rate, reduce mortality rate.

Design concept of the present utility model is achieved in that joins together a kind of special gastrolavage tube by a snare and gastroscope, form the gastroscope gastrolavage tube of direct-view gastric lavage down.The material that this pipe adopts that silicon is moulded, glue and titanium dioxide are hybridly prepared into, color is white in color, soft durometer, the caliber thickness of pipe matter are suitable, can with the supporting use of gastroscope, do not have when the thickness of pipe wall thinness can guarantee vacuum suction and subside, the perforate of pipe front end can guarantee the concentrated flushing of current, and the pipe rear end adds the function that Y-shaped three passes to increases this pipe, by the control snare, gastroscope is separated with gastrolavage tube be convenient to the two to work independently in addition.

This utility model is made up of gastrolavage tube, snare pipe and gastroscope.

Below in conjunction with accompanying drawing this utility model is further described:

Fig. 1 is an outside drawing of the present utility model.

Fig. 2 is this utility model front-end architecture sketch map.

Fig. 3 is this utility model middle-end sketch map.

Fig. 4 is this utility model Y-shaped three-port structure sketch map

Wherein: (1) Y-shaped threeway, (2) transparent hose, (3) scale, (4) side opening, (5) metal conduction silk, (6) caliber

Embodiment of the present utility model is: adopt with silicon mould, the material of glue and titanium dioxide mixed preparing makes this pipe, color is white in color, opaque, tube wall is highly polished, its soft durometer is moderate, pipe thickness is 0.5mm, and indicates scale (3) pipe and can be designed to different size, and caliber (6) is respectively:

External diameter: 5mm, internal diameter 3.5mm-4mm

6mm， 4.5-5mm

7mm， 5.5-6mm

8mm， 6.5-7mm

The length of pipe can be 12cm-14cm.Be provided with 2-3 side opening (4) in addition apart from the about 30mm of this pipe front end tapping, pitch-row 10-12cm, pore size changes (changing) with the variation of caliber in 3-5mm, the rear end of stomach tube is a transparent hose (2), is observation window, in order to observe suction gastric thing or blood, one chamber of Y-shaped threeway (1) connects transparent hose (2), the chamber connects paunch flusher one of in other two chamber, and metal conduction silk (5) is inserted in another chamber, also the conducting silk can be transferred to the changing-over syringe.This stomach tube is fused by snare and gastroscope, and the front end of pipe is exposed to gastroscope 3-5mm, forms direct-view gastric lavage gastrolavage tube under the complete gastroscope.Wherein snare is to be locked by inserting gastroscope movable detecting hole and gastrolavage tube.

Work process: will insert esophagus, gastrolavage tube front end 3-5mm with the gastrolavage tube that gastroscope fuses simultaneously and be exposed to before the gastroscope visual, inject medicinal liquid or clear water with syringe, the limit flushing, the limit is observed, insert on the limit, connect paunch flusher clear water gastric lavage after advancing stomach, stop up gastrolavage tube as the gastric hematocele more, to dredge in the metal conduction silk insertion tube, utilize this conducting silk to be convenient to the propelling of gastrolavage tube, pull out or turn to, need injectable drug or can transfer to metal conduction silk changing-over syringe when the part washed.After washing stomach, can gastrolavage tube and gastroscope be separated, gastrolavage tube is kept somewhere gastric as beam food conduit or reduced pressure conduit by the control snare; Also can carry out local hemostasis to hemorrhage rotting through this conduit or gastroscope movable detecting hole.

Advantage part of the present utility model is: to the massive bleeding from upper digestive tract patient, utilize this pipe to become two The inferior damage that reduces as once advancing mirror take enterprising mirror, and can be reliably clear in the direct view under endoscope accurate and effective Except hematocele, in time assign a cause for an illness or the bleeding part, implement therapeutic scheme, save time for giving emergency treatment to a patient. This manages nontoxic aseptic, and thing is supported inexpensive, has several functions, and is easy to use.
