More detailed description:
Embodiment 1
Improvement is made on the basis of existing single-lumen bronchial tube, is please referred to shown in Fig. 1, and existing conduit includes conduit sheet
Body, catheter body are a hose, and one end of hose is provided with plug 6, and the other end is provided with the company for connecting with ventilator
Connect port 3；The adjacent position of plug 6 is provided with the first cuff 1, and the first cuff 1 is communicated with the first gas tube 2 across hose,
The drawbacks of end of first gas tube 2 is provided with the first inflatable structure part, the conduit is that the adjacent position of plug 6 is only arranged
One cuff 1 causes when plug 6 to be inserted into from disease population, is only capable of realizing one-lung ventilation or double according to insertion depth or position
Pulmonary ventilation, and cannot easily carry out conversion between the two；And plug 6 is led when carrying out one-lung ventilation to right lung due to controlling
Bronchus dissection is different, causes conduit 6 to be difficult to successfully block right upper lung, and the length of conduit is also often difficult to reach during surgery
It is required that；The disposable single lumen endobronchial tube of the present embodiment is made as follows in the basis life of existing single-lumen bronchial tube
It improves:
It on the opposite catheter body place horizontal alignment of plug 6 or is bent downwardly, to approach Human Physiology camber, increases intubation
Success rate；
Be provided with the second cuff 4 close to the first cuff 1 on hose and far from plug position, the second cuff 4 be communicated with across
Second gas tube 5 of hose, the end of the second gas tube 5 are provided with the second inflatable structure part 8, and double cuff design facilitates not
The conversion of one-lung ventilation and double pulmonary ventilation is carried out under the premise of adjusting depth of catheter；
The internal diameter of plug 6 is slightly smaller than inner diameter, and it acts as be convenient for intubation；
First cuff 1 is apart from plug ends 3-5cm；The length range of first cuff 1 be 1-2.5cm, such as 1.2cm,
1.5cm and 1.8cm value etc. within the scope of this, the length of existing first cuff 1 is too long, and defect is to reduce right upper lung
Block successful probability；Second cuff, 4 distance the first cuff 8-10cm, can any value in the range.First inflation knot
The end of component 7 is provided with the first charge valve, and the end of the second inflatable structure part is provided with the second charge valve；First inflatable structure
Part 7 is identical as the construction of the second inflatable structure part 8, and the first charge valve is identical as the construction of the second charge valve.The length of conduit
For 35-40cm, equally, any value can be met the requirements within the scope of this, and the effect of elongate catheter is to meet all patients' differences
The requirement of catheter depth；It is preferred that the length of conduit is 38cm.It is additionally provided on plug 6 curved with respect to horizontal line where it with plug 6
The opposite ligule ancillary structural member 9 of bent angle, it acts as the accurate positionin in subsidiary conduit insertion process, increase is blocked successfully
The angle of rate, ligule ancillary structural member 9 and conduit is 18-22 degree, and preferably 20 degree herein, the length of ligule ancillary structural member is
0.5-1cm, can any value in the range.Plug 6 is 160-180 degree, the angle with respect to horizontal line slight curvature where it
Degree is determined according to the anatomical angulation between left and right main bronchus and main tracheae, is conducive to conduit and is entered the main branch gas in left or right side
Pipe.The length of conduit and its inner diameter are in corresponding relationship, the single lumen endobronchial tube of this kind of corresponding relationship and the prior art
Internal diameter is consistent with the corresponding relationship of length in model.For each model, the internal diameter of plug 6 0.5mm small with respect to inner diameter.
Disposable single lumen endobronchial tube in the present embodiment, can ensure the smooth progress of surgical procedure, and disease is effectively reduced
The stimulation of trouble, increases its comfort level, further expands its clinical scope of application, it is practical to have played single lumen endobronchial tube
Outstanding advantage, and lower production costs, universality is stronger, convenient for making for more medical staff, especially grassroots medical worker
With.
The disposable single lumen endobronchial tube of the present embodiment is used for practical operation:
Patient's operating condition: patient's conventional cardiac monitoring after entering the room monitors blood pressure, heart rate, pulse oxygen saturation.Anesthesia lures
It leads: midazolam 0.05mg/kg, 1.5~2.0mg/kg of propofol, 0.6 μ g/kg of sufentanil, rocuronium 0.9mg/kg.
Male 7.5~8.0, and women 7.0~7.5.The promoting the circulation of qi cannula after flesh pine is improved.Using Drager Anesthesia machine row mechanical ventilation,
6~8ml/kg of tidal volume, 12 times/min of respiratory rate, inspiratory/expiratory 1: 2.
Disposable single lumen endobronchial tube localization method (1) stethoscopy of the present embodiment: by the primary of the present embodiment
Property using single lumen endobronchial tube intubation after, first to the second cuff gas injection, be advisable so that positive airway pressure air flue is air tight.After auscultation
If double pulmonary respiration sounds are identical, show the conduit in main tracheae.It will continue to be placed in tracheal catheter after second cuff deflation, wait encounter resistance
2~3cm is continued into after power.Respectively to the first cuff and the second cuff gas injection, check that two pulmonary respiration sounds, such as non-ventilating lung are exhaled
Sound-absorbing disappears, and ventilation pulmonary respiration sound is normal, thinks to reach good lung isolation effect at this time.If double lungs after the first cuff gas injection
Equal audible and breath sound, prompt conduit excessively shallow；As only hear after the first cuff gas injection and unilateral lung breath sound but right upper lung do not hear and
Peak airway pressure is higher than 40cmH2O when breath sound or one-lung ventilation, prompts the conduit too deep, should make corresponding adjustment.(2) fiber
Bronchoscope (FOB) method: accurately " goldstandard " whether this be to judge trachea cannula position.Quasi- insertion left mainstem bronchus person,
FOB is inserted into tracheal catheter, visible left bronchial lumen, upper left, lower lobe bronchus opening at catheter opening.Quasi- insertion is right
Side main bronchus person, is inserted into tracheal catheter for FOB, the visible right bronchus at catheter opening, front it is visible the right side in, lower lung
Leaf bronchus opening is open by the visible upper right lobar bronchi of conduit side opening.
