Description
Technical field
The present invention relates to medical appliance, the complete built-in laryngeal mask associating breather of especially a kind of endotracheal tube.
Background technology
The operation that anaesthetizes sb. generally time need to carry out assisted respiartion to keep General Anesthesia Undergoing hemodynamic stability to surgical patient, conventional assisted respiartion breather comprises endotracheal tube breather and laryngeal mask respiratory ventilation device.
The tracheal tube that endotracheal tube breather consists of an elongated tubular forms, and at the far-end of elongated tubular, is furnished with an inflatable sacculus.In operating process, the far-end of tracheal tube is inserted into patient's oral cavity, and enters in patient's trachea through throat's entrance (or being called glottis opening) of patient.Once this tracheal tube is so positioned, described inflated is formed to sealing to the inner passage of trachea.After forming sealing, the near-end of this pipeline is applied to normal pressure with the lung inflation to patient.The advantage of endotracheal tube is, it can bear larger sealing load, is difficult for gas leakage.And its major defect is, be difficult to suitably pipeline be inserted, too high to the specification requirement of actual operator.Except this major defect, also there is the other defect being associated with tracheal tube.For example, tracheal tube often makes patient feel violent " having sore throat ".This " having sore throat " is mainly to be caused by the friction between the recess between described pipeline and patient's cartilaginous tissue, can also cause the violent cough reflex of patient.
Contrary with tracheal tube, laryngeal mask airway device can insert relatively easily in patient body and set up a respiration channel.In addition, laryngeal mask airway device is that the reason that a kind of " can make us bearing " installs is: even it is inserted improperly, this laryngeal mask airway device still can be set up a respiration channel.Therefore, laryngeal mask airway device is often considered to a kind of " help " device.In addition, can only by being carried out to less control action, patient's head, neck and oral cavity just laryngeal mask airway device can be inserted.In addition, this laryngeal mask airway device does not need to contact with the inner passage of trachea sensitivity just can be to patient's lung inflation, and the size of the respiration channel of being set up by this laryngeal mask airway device is significantly greater than the size of the respiration channel of being set up by tracheal tube.And the major defect of laryngeal mask airway device is, cost is high, and sealing load is too small and to cause gas leakage, patient's position to require high, to other special postures patient easily displacement cause controlling and ventilate unsuccessfully.
Current endotracheal tube breather and laryngeal mask airway device are generally separately independently assisted respirator, its mutual replacing is very inconvenient, and in conversion breathing pattern, often easily cause due to anesthesia early extubation, make air flue produce a series of complication that hypersusceptibility causes, make operation have unpredictable unfavorable factor.
Although, the built-in laryngeal mask of trachea appears in some patent documentations, as Chinese patent ZL02819802.6 and US Patent No. 5303697, but, its endotracheal tube is not built in laryngeal mask conduit completely, in actual replace tubes operating process, endotracheal tube easily comes off, and the update of endotracheal tube is also inconvenient.

Preferably, as shown in figure 14, guide hole 111 is comprised of vertical guide hole and horizontal guide hole, and vertical guide hole is combined into L-type with horizontal guide hole.When push button 123 pushes, laterally guide hole can be used as location structure, endotracheal tube is moved to push button 234 and from vertical guide hole, snap fit onto horizontal draw-in groove, endotracheal tube 12 location of linking closely.
When promoting push button 123 along guide hole 111, endotracheal tube 12 is released, and built-in endotracheal tube 12 is pushed into by patient's glottis among patient airway, and the present invention changes endotracheal tube into and inserts duty.When endotracheal tube moves push button 21 and is pushed to the end of guide hole 111, built-in endotracheal tube 2 stretch out arrival extreme position, by aerating device, sealing ring 16 is inflated, make sleeve pipe 15 and endotracheal tube 12 form sealing, gas can not spill from guide hole 111, can be from gas leakage between endotracheal tube 12 and laryngeal mask conduit 11 yet.While regaining endotracheal tube 12, by aerating device, sealing ring is exitted, mobile push button 21 makes endotracheal tube 12 rollbacks, and endotracheal tube 12 is concealed in laryngeal mask conduit 11 again.
Laryngeal mask material of the present invention all adopts the high material of Medical patient biocompatibility to make, nontoxic non-stimulated.Cover body can select soft silica gel material and design consistent with the profile of bottleneck throat, reduce to greatest extent human body stimulated, improve the sealing of Liao Yu throat.Laryngeal mask conduit middle and upper part is through strengthening, and convenient operation conduit moves push button and prevents that tooth stings flat trachea.Endotracheal tube smooth pliable, transparency is high, and anti-warpage is splendid.
The present invention is easy to use, and structure one is simple to operate, and intubation way can convert as required at any time, and built-in endotracheal tube can be adjusted in real time in the endotracheal degree of depth.Can produce various models, applicable all ages and classes, sex, various operation position crowd.Particularly, in the clear-headed process of patient, can at any time endotracheal tube pattern be converted to laryngeal mask pattern, tube drawing complication after the various anesthesia that the untoward reaction of minimizing air flue causes.
Main feature and purposes: for perioperative anesthesia early extubation, prevent from that tube drawing from choking to cough the complication of the airway hyper-reaction causing, prevent airway pressure generation obstacle after tube drawing, as glossoptosis, respiration inhibition etc.Be applicable to all general anesthesia operations, various age and sex, particularly brain surgical patient.
The clinical effectiveness reaching of the present invention is as follows:
1) reducing craniocerebral operations during extubation chokes and coughs that the intracranial pressure causing sharply raises, hemorrhage, Brain shift;
2) reduce the cardiovascular response that stress cause, as wound bleeding, cerebral hemorrhage, the complication such as myocardial infarction;
3) prevent that the surgical wound surface that other operations cause is hemorrhage;
4) minimizing is choked to cough and is caused abdominal pressure to raise, wound dehiscence;
5) prevent from anaesthetizing vomiting in rear asphyxia and emergence process, mistake suction, glossoptosis.
The above is the preferred embodiment of the present invention; certainly can not limit with this interest field of the present invention; should be understood that; for those skilled in the art; technical scheme of the present invention is modified or is equal to replacement, do not depart from the protection domain of technical solution of the present invention.
