Description
Technical field
The present invention relates to a kind of visual voltage regulation type trachea cannula, it is related to medical devices field.
Background technology
The inflation method that clinically often uses is that operator pinches the exposed small detection air bag communicated with air bag with hand and estimated at present
Survey the pressure of catheter air bag, this method because personal experience it is different in clinical anesthesia work caused by cuff pressure difference very
Greatly.Too low cuff pressure can cause the various secretion of pars oralis pharyngis (including：Courageous and upright point caused by the gastric content of reflux, operation
Secretion etc.) by cuff, aspiration pneumonia is caused, the lighter, which extends length of patient stay, increases patient burden, and severe one even jeopardizes
Life.Too low cuff pressure can also cause the gas leakage of lung ventilator loop, cause hypoventilation.Too high cuff pressure can cause gas
Pipe mucosa edema, ischemic, or even necrosis, patient is postoperative to there is cough, pharyngeal discomfort, increases patient's sense of discomfort, and reducing patient expires
Meaning degree.And the sensitive patients of prolonged operationses or ICU long-times with pipe, tracheae is seriously narrow after too high set bag pressure can cause tube drawing
Narrow, the later stage even needs operative treatment.
Prolonged operationses need the critical patient intra-cuff pressure meeting with pipe for a long time reduce because of cuff gas leakage, if
Cuff does not obtain the risk that inflation in time can cause gas leakage and increase to inhale by mistake.The modus operandis such as laparoscope can make intra-cuff pressure
Rise, increases postoperative bottleneck throat complication rate；The change of position also can produce certain influence to set bag pressure, be intubated rear enclosure
The change of bag pressure power, feasible monitoring method is lacked in clinic, and easily ignored by clinician, cause patient it is postoperative not
It is suitable, increase trachea cannula associated complication, cause the financial burden that patient is unnecessary.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of visual voltage regulation type trachea cannula, it is intended to pass through larger capacity
Elastic air storage bag cuff because indwelling catheter time extend leak air when, air storage bag can by automatically to sheathed catheter capsule inflate buffer
The intracapsular pressure change of sheathed catheter, so as to reduce the risk of aspiration pneumonia and respiratory cycle gas leakage, increase the security of patient.
In order to solve the above technical problems, the technical solution used in the present invention is：A kind of visual voltage regulation type trachea cannula, its
It is characterised by, including intubation, being arranged on the cuff of cannula end, the air storage bag penetrated by conduit, walled conduits and cuff,
It is located on air storage bag and to the check valve of air storage bag inner inflatable；The walled conduits are located inside intubation tube wall；The gas storage
The gas capacity of capsule and the ratio of cuff are 4-8:1.
Further technical scheme is that the air storage bag is provided with the pressure gauge of detection air storage bag internal gas pressure.
Further technical scheme is that the check valve includes hitching post, and described hitching post one end passes through sheathed spring and list
Contacted to valve body, middle part is provided with and compresses disk and be arranged sealing ring and check valve valve body contact, and the other end is provided with pushing block.
It is using beneficial effect caused by above-mentioned technical proposal：The present invention is existed by the elastic air storage bag of larger capacity
When cuff leaks air because indwelling catheter time extends, air storage bag can be by inflating the intracapsular pressure of buffering sheathed catheter to sheathed catheter capsule automatically
Power changes, so as to reduce the risk of aspiration pneumonia and respiratory cycle gas leakage, when causing the intracapsular pressure of sheathed catheter because of various factors
During power increase, cover intracapsular gas meeting automatic back flow and enter elastic air storage bag, avoid the change of intra-cuff pressure excessive, because air storage bag
There is gas gauge inside, and medical worker can easily observe cuff pressure, when the visual voltage regulation type trachea cannula provides long
Between set bag pressure that is stable and being adapted to patient, increase the security of patient, reduce perioperative because cuff pressure occur it is various simultaneously
Disease is sent out, while also mitigates the work load of medical worker.
Pressure gauge is set at conduit air storage bag end, is easy to make pressure value when allowing operator to be sleeve bag gas-filling and objectively sentences
It is disconnected, and be easy to find the pressure changing with pipe patient's cuff, it is adjusted in time, so that conduit cuff is protected all the time
Hold suitable stress level (20-30cmH2O), it is related effectively to reduce the trachea cannula caused by cuff pressure is too high or too low
Property complication.

Embodiment
With reference to the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Ground describes, it is clear that described embodiment is only the part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Many details are elaborated in the following description to facilitate a thorough understanding of the present invention, still the present invention can be with
It is different from other manner described here using other to implement, those skilled in the art can be without prejudice to intension of the present invention
In the case of do similar popularization, therefore the present invention is not limited by following public specific embodiment.
As illustrated, disclosure sets forth a kind of visual voltage regulation type trachea cannula, it is characterised in that including intubation 1, if
Put and be intubated the cuff 2 of 1 end, the air storage bag 6 penetrated by conduit 5, walled conduits 4 and cuff 2, be located on air storage bag 6 and
To the check valve 9 of the inner inflatable of air storage bag 6；The walled conduits 4 are located inside intubation tube wall 3；The gas of the air storage bag 6 holds
The ratio of amount and cuff 2 is 4-8:1.The air storage bag 6 is provided with the pressure gauge 8 of the detection internal gas pressure of air storage bag 6.It is described
