Abstract

The invention relates to a bronchial catheter with a single cavity and double sacs, comprising a single-cavity catheter, a catheter interface, a breathing loop adapter (including a bronchofiberscope inlet, an inlet cap, a sampling tube and a breathing loop interface), a drainage tube interface, a drainage tube interface cap, a drainage tube, a trachea air sac inflation tube, a trachea air sac air valve, a trachea air sac, a bronchial air sac inflation tube, a bronchial air sac air valve, a bronchial air sac, an affected side blocking segment, a drainage tube opening, a bronchial catheter opening, a carina pothook and a single-side indicatrix. The invention has the advantages that the pipe diameter of the bronchial catheter is approach to that of a common bronchial catheter with a single cavity, the catheter is convenient to replace and is not easy to damage; a remote end arc-shaped structure has a guiding function and is convenient to locate; single or double lungs are regulated to aerate through the inflation and the deflation of the air sacs, which is simple, convenient and flexible; the double sacs are good in structure fixation, are not easy to move and have high safety; the drainage tube can assist in draining, exhausting and repeatedly expanding of the side lung of a patient and ensure the aerating effect, and the near end of the drainage tube can be sealed; and the bronchial catheter can ensure safe operation and is simple and convenient to operate.

Description

The single cavity double sac bronchial catheter

Technical field

The present invention relates to a kind of operation whole process or part of being applicable to and need the single cavity double sac bronchial catheter of the clinical endotracheal anesthesia of one-lung ventilation.

Background technology

At present, the endotracheal tube of the clinical one-lung ventilation set up commonly used existing several, but dissatisfactory aspect is arranged all.The double lumen endobronchial tube the most frequently used as present one-lung ventilation, management is comparatively complicated in its intubation technique and the art, grasp the improper hypoxemia that easily causes, and because of the conduit external diameter is thicker, often puts the pipe difficulty clinically or cause respiratory tract injury, and two lungs are separated and located than difficulty etc., in addition also too thin because of catheter diameter, the airway resistance height, alternative model is less, often is subjected to certain limitation in clinical practice; Though the bronchial obstruction conduit of Tui Chuing has solved basically and has put the pipe difficult problem in recent years, but its price is too high, be not suitable for promoting clinically, it puts complexity of pipe process simultaneously, generally need under the branchofiberoscope direct-view, insert, China carries out blind inserting mostly when inserting the bronchial obstruction sleeve pipe because of the limitation of conditions, because no branchofiberoscope guiding, need the bronchial obstruction catheter length of inserting is estimated, complicated operating process, and run into the full problem of obstruction of lung when making the bronchial obstruction catheter displacement during patient's tractive lung in the art, address this problem the position that also needs mobile bronchial obstruction pipe, select suitable conduit or connect vacuum suction etc., be exactly that bronchial obstruction pipe tube chamber is tiny in addition, inhale difficulty of expectorant, abundant expectoration and can do continuous negative pressure suction when thin, as expectorant than thickness or the clot sucking-off is arranged at need, also need with attraction again after the seal wire mediation, it is a kind of real easy to operate accurate also still not have clinically at present, drain is unobstructed, the ideal one-lung ventilation conduit of advantages such as single two pulmonary ventilation conversion is flexible.

Summary of the invention

The present invention be directed to a kind of ideal one-lung ventilation conduit of above not enough design, i.e. single cavity double sac bronchial catheter, its have easy to operate accurately, advantage such as unobstructed, the single two pulmonary ventilation conversions of drain are flexible, for clinical practice has brought convenience.

The present invention solves the technical scheme that its technical problem takes:

The single cavity double sac bronchial catheter, it comprises: single lumen catheter, catheter interface, breathing circuit adapter

(comprising: fibre bronchus mirror's inlet, access cap, sampling tube, breathing circuit interface), drainage tube interface, drainage tube interface medicated cap, drainage tube, trachea airbag inflation pipe, trachea air bag air valve, trachea air bag, bronchus airbag inflation pipe, bronchus air bag air valve, bronchus air bag, Ipsilateral occluded segment, drainage tube opening, endotracheal tube opening, knuckle hook, one-sided indicatrix; Wherein, the endotracheal tube opening is positioned at the single lumen catheter side, and the trachea air bag is positioned at endotracheal tube opening top; The Ipsilateral occluded segment is the arc solid tubes, and subsidiary bronchus air bag, is used to block non-ventilation side lung, the bronchus air bag charge and discharge the single two pulmonary ventilation of scalable; The built-in drainage tube of tube wall helps the drain of Ipsilateral lung, and the drainage tube opening is positioned at Ipsilateral and blocks the paragraph header section, and the knuckle hook is positioned at Ipsilateral occluded segment and endotracheal tube opening junction; The drainage tube interface is the standard syringe interface, and attached mouthful of medicated cap, and catheter interface is a standard endotracheal tube interface, and subsidiary matching used three way cock is breathing circuit adapter (comprising: fibre bronchus mirror's inlet, access cap, sampling tube, breathing circuit interface);

Description of drawings

Fig. 1 is a front view of the present invention;

The specific embodiment

As shown in Figure 1, a kind of single cavity double sac bronchial catheter, it comprises: single lumen catheter 1, catheter interface 2, breathing circuit adapter 3 (comprising: fibre bronchus mirror inlet 3-1, access cap 3-2, sampling tube 3-3, breathing circuit interface 3-4), drainage tube interface 4, drainage tube interface medicated cap 5, drainage tube 6, trachea airbag inflation pipe 7, trachea air bag air valve 8, trachea air bag 9, bronchus airbag inflation pipe 10, bronchus air bag air valve 11, bronchus air bag 12, Ipsilateral occluded segment 13, drainage tube opening 14, endotracheal tube opening 15, knuckle hook 16, one-sided indicatrix 17; Wherein, endotracheal tube opening 15 is positioned at single lumen catheter 1 side, and trachea air bag 9 is positioned at endotracheal tube opening 15 tops; Ipsilateral occluded segment 13 is the arc solid tubes, and subsidiary bronchus air bag 12, is used to block non-ventilation side lung, bronchus air bag 12 charge and discharge the single two pulmonary ventilation of scalable; The built-in drainage tube 6 of tube wall helps the drain of Ipsilateral lung, and drainage tube opening 14 is positioned at 13 sections of Ipsilateral occluded segment, and knuckle hook 16 is positioned at Ipsilateral occluded segment 13 and endotracheal tube opening 15 junctions; Drainage tube interface 4 is the standard syringe interface, and attached drainage tube interface medicated cap 5, catheter interface 2 is standard endotracheal tube interfaces, and subsidiary matching used three way cock is breathing circuit adapter 3 (comprising: fibre bronchus mirror inlet 3-1, access cap 3-2, sampling tube 3-3, breathing circuit interface 3-4);

Described single cavity double sac bronchial catheter, in operating process, cross glottis with the normal mode intubate, rotary guide pipe points to the arc far-end bronchus (drainage tube has directed indicative function) of Ipsilateral lung, passage is positioned at the trachea carina top, the far-end solid section enters the Ipsilateral bronchus and is correct location (air bag resistance or fibre bronchus mirror can assist the location), give the airbag aeration A/C, the far-end air bag charge and discharge the single two pulmonary ventilation of scalable; Drainage tube can attract Ipsilateral gas and liquid, and near-end can be airtight.
