Abstract

The invention relates to a movable trachea cannula catheter which comprises a short trachea cannula, an internal tracheal catheter and a tracheal catheter joint. The internal tracheal catheter is disposed in the short trachea cannula, and is capable of moving and rotating in the same and shorter than the same; the short trachea cannula and the internal tracheal catheter form the complete movable trachea cannula catheter; the end portion of the rear end of the internal tracheal catheter is connected with an anaesthesia machine threaded tube through the tracheal catheter joint; the front end of the internal tracheal catheter is made into a certain camber by a process, so that convenience is brought to the internal tracheal catheter to be inserted into the left bronchus or right bronchus.

Description

Movable air pipe-in-pipe conduit

Technical field

The present invention relates to a kind of medical apparatus and instruments, relate in particular to a kind of bronchial catheter.

Background technology

One-lung ventilation refers to that thoracic surgery patient only utilizes a side lung (non-operation side) by respirator, to be carried out method or the means of mechanical ventilation through endotracheal tube in art, can make art side lung static, wither, facilitate operation technique; Also play the effect of strong Ipsilateral lung isolation.At present conventional one-lung ventilation device mainly contains double lumen endobronchial tube intubate clinically, bronchus shutoff pipe, however there is certain technological deficiency in this double lumen endobronchial tube intubate.

1. location difficulty, usually needs repeatedly to debug, and even need to prop up location, border by fibre, time-consuming.

2. ventilation complex management, requires high to anesthesia doctor level, experience.

3. double lumen tube external diameter is larger, is not suitable for child and uses.

4. double lumen endobronchial tube Postoperative and anesthesia is replaced with endotracheal tube as the client need that need to carry out respirator treatment with pipe.

Summary of the invention

The object of the present invention is to provide a kind of simple to operately, easy to use, the reliable a kind of movable air pipe-in-pipe conduit of one-lung ventilation, for one-lung ventilation anesthesia surgery.

For realizing above-mentioned technical purpose, provide following technical scheme:

A kind of movable air pipe-in-pipe conduit, comprise brachytracheae sleeve pipe, built-in endotracheal tube and catheter slipjoint, wherein built-in endotracheal tube is built in tracheal casing pipe, and can be in air pipe sleeve in-pipe and rotation, and built-in endotracheal tube length is greater than brachytracheae sleeve pipe; Described brachytracheae sleeve pipe and built-in endotracheal tube form a complete movable air pipe-in-pipe conduit; End, built-in endotracheal tube rear end connects anaesthetic apparatus screwed pipe by catheter slipjoint and connects; Endotracheal tube front end is made into certain radian through technique, is convenient to insert to left bronchus or right bronchus.Use this pipe to complete after tracheal intubation, according to operation needs, built-in endotracheal tube is passed forward to left or right bronchus, carry out one-lung ventilation; In operation end or art, need, built-in endotracheal tube is exited to bronchus to trachea and carry out two pulmonary ventilation.

For making the present invention more practical, now the present invention is made further improvements:

On built-in endotracheal tube and brachytracheae sleeve outer wall, be provided with scale, for judging that brachytracheae sleeve pipe enters the trachea degree of depth, built-in endotracheal tube enters the bronchus degree of depth.

Accurately the bronchial cannula difficulty of location is large, and specification requirement is high, for making intubate more reliable, at built-in endotracheal tube front end, places visual probe, makes intubate more accurate.

Beneficial effect of the present invention is:

1. remove existing double lumen endobronchial tube Postoperative and anesthesia from and need to carry out with pipe respirator treatment patient's replacing endotracheal tube process.2. avoid difficult airway patient double lumen endobronchial tube Postoperative and anesthesia to carry out the danger that respirator treatment patient changes the unsuccessful generation anoxia of endotracheal tube with pipe; Avoid replace tubes difficulty mistake that endotracheal tube is inserted to esophagus and particularly esophagus surgical stapling mouth is caused the risk of damage; Owing to there being sleeve pipe, also having avoided the ventilation of double lumen endobronchial tube anesthesia surgery more than once not adjust conduit throat, vocal cords, trachea have been caused to damage.

3. use this conduit to complete the technical difficulty of bronchial cannula less than existing double lumen tube intubate and various bronchus shutoff pipe, easy operating, saves intubation time, is convenient to universal use, especially at intermediate and small hospital, promotes, and one-lung ventilation is reliable.

4. the production technology of this product is simple, relatively has price advantage with the double lumen tube of existing use, various shutoff pipe, reduces Medical Expense for Patients, has obvious social benefits.

The specific embodiment

For a better understanding of the present invention, below in conjunction with accompanying drawing, be described further:

As shown in Figure 1, a kind of movable air pipe-in-pipe conduit, comprise brachytracheae sleeve pipe 4, built-in endotracheal tube 5 and catheter slipjoint 1, wherein built-in endotracheal tube 5 is built in tracheal casing pipe 4, and can be in the interior movement of tracheal casing pipe 4 and rotation, built-in endotracheal tube 5 length are greater than brachytracheae sleeve pipe 4; Described brachytracheae sleeve pipe 4 and built-in endotracheal tube 5 form a complete movable air pipe-in-pipe conduit; Built-in endotracheal tube 5 ends, rear end connect anaesthetic apparatus screwed pipe by catheter slipjoint 1; Built-in endotracheal tube 5 front ends are made into certain radian through technique, are convenient to insert to left bronchus or right bronchus.

At brachytracheae sleeve pipe 4 front ends, near end, be provided with air bag 1, at built-in endotracheal tube 5 front ends, near end, be provided with air bag 23; Air bag 1 connects charge valve 1 by gas tube 1, and air bag 23 connects charge valve 2 32 by gas tube 2 31.Described gas tube 1 and gas tube 2 31 are embedded in respectively in built-in endotracheal tube 5 and brachytracheae sleeve pipe 4 walls.

On built-in endotracheal tube 5 and brachytracheae sleeve pipe 4 outer walls, be provided with scale, for judging that brachytracheae sleeve pipe 4 enters the trachea degree of depth, built-in endotracheal tube 5 enters the bronchus degree of depth.
