Description
Technical field
The present invention relates to medical appliance, the completely built-in laryngeal mask joint air-breather of especially a kind of tracheal catheter.
Background technology
The operation that anaesthetizes sb. generally when need to carry out assisted respiartion to operation patients to keep General Anesthesia Undergoing blood flow
Mechanics is stable, and conventional assisted respiartion air-breather includes tracheal catheter air-breather and laryngeal mask respiratory ventilation device.
The tracheal tube that tracheal catheter air-breather is made up of an elongated tubular is formed, and one is disposed with the distal end of elongated tubular
Individual inflatable sacculus.In operation, the distal end of tracheal tube is inserted into the oral cavity of patient, and enters by the throat of patient
Mouth (or being glottis opening) enters in the tracheae of patient.The tracheal tube is once so positioned, then the sacculus is filled
Gas and sealing is formed to the inner passage of tracheae.After the sealing is formed, apply normal pressure to the near-end of the pipeline with to disease
The lung inflation of people.The advantage of tracheal catheter is that it can bear larger seal pressure, be not easy gas leakage.And its major defect
It is, it is difficult to suitably pipeline is inserted, it is too high to the technical requirements of actual operator.In addition to this major defect, also
In the presence of the other defect associated with tracheal tube.For example, tracheal tube often makes patient feel violent " having sore throat ".This
Kind " having sore throat " as caused by the friction between the recess between the pipeline and patient's cartilaginous tissue, can also mainly cause
The violent cough reflex of patient.
With tracheal tube on the contrary, laryngeal mask airway device can relatively easily insert in patient body and establish a breathing and lead to
Road.In addition, laryngeal mask airway device is the reason for being a kind of " can make us bearing " device：Even if being improperly inserted into,
The laryngeal mask airway device can still establish a respiration channel.Therefore, laryngeal mask airway device is often referred to as a kind of " help " dress
Put.In addition, laryngeal mask airway device can only can be inserted by carrying out less control action to the head, neck and oral cavity of patient.
It can be inflated in addition, the laryngeal mask airway device need not be in contact with the inner passage of tracheae sensitivity to the lung of patient, by the larynx
The size for the respiration channel that cover air-breather is established is noticeably greater than the size for the respiration channel established by tracheal tube.And larynx
The major defect of cover air-breather is, cost is high, and seal pressure is too small and cause gas leakage, and the position of patient requires high, right
Easily displacement causes control ventilation failure to other special postures patient.
Current tracheal catheter air-breather and laryngeal mask airway device are usually each independent assisted respirator, its phase
Replacing between mutually is inconvenient, and tends to be caused by anaesthetizing early extubation when breathing pattern is changed, and makes gas
A series of complication caused by road produces hypersusceptibility, makes operation unpredictable unfavorable factor be present.
Although the built-in laryngeal mask of tracheae is appeared in some patent documents, such as Chinese patent ZL02819802.6 and U.S.

The effect of ring 16 is to prevent the gas leakage between tracheal catheter 12 and laryngeal mask conduit 11, and prevents the gas leakage of guide hole 111.
Preferably, as shown in figure 12, sealing ring 16 is fixedly installed on the inwall of tracheal catheter 12, can be moved with tracheal catheter 12
It is dynamic.In the moving process of tracheal catheter 12, the position of sealing ring 16 is all the time on the lower end of sleeve pipe 15.
Preferably, sealing ring 16 is air-tight pneumatic sole ring, and the inflation ring is connected with the first aerating device 4（Do not show in figure
Go out）.
Preferably, as shown in figure 14, guide hole 111 is made up of vertical guide hole and horizontal guide hole, and vertical guide hole is with laterally leading
Combine l-shaped in hole.When push button 123 pushes, horizontal guide hole can be used as location structure, and tracheal catheter is moved into push button 234 from perpendicular
Snapped fit onto to guide hole in horizontal card slot, tracheal catheter 12 links closely positioning.
When promoting push button 123 along guide hole 111, tracheal catheter 12 is released, and built-in tracheal catheter 12 passes through patient's glottis
It is pushed among patient airway, the present invention is changed into tracheal catheter insertion working condition.When tracheal catheter movement push button 21 pushes away
When moving the end of guide hole 111, built-in tracheal catheter 2 is reached up to extreme position, and sealing ring 16 is filled by aerating device
Gas so that sleeve pipe 15 and tracheal catheter 12 form sealing, and gas will not be spilt from guide hole 111, also will not be from tracheal catheter 12
The gas leakage between laryngeal mask conduit 11.When withdrawing tracheal catheter 12, sealing ring is deflated by aerating device, mobile push button 21 makes gas
Pipe conduit 12 is retracted, and tracheal catheter 12 is concealed in laryngeal mask conduit 11 again.
The laryngeal mask material of the present invention is made using the high material of Medical patient biocompatibility, nontoxic non-stimulated.Cover body can
Silica gel material and design from softness is consistent with the profile of bottleneck throat, reduces to human body stimulation, improves and larynx to greatest extent
The sealing in portion.By strengthening, conduit easy to operation moves push button and prevents tooth to sting flat tracheae for laryngeal mask conduit middle and upper part.Tracheae
Conduit smooth pliable, transparency is high, resists flexibility splendid.
Easy to use, structural integrity of the invention, simple to operate, intubation way can convert at any time as needed, built-in tracheae
Conduit can adjust in real time in endotracheal depth.Various models can be produced, are applicable all ages and classes, sex, various operation position people
Group.It can be at any time laryngeal mask pattern by tracheal catheter patten transformation particularly during patient is clear-headed, it is bad anti-to reduce air flue
Tube drawing complication after various anesthesia caused by answering.
Main feature and purposes：Early extubation is anaesthetized for perioperative, prevents that tube drawing from choking airway hyper-reaction caused by cough
Complication, obstacle, such as glossoptosis, respiration inhibition occur for airway pressure after preventing tube drawing.Suitable for all general anesthesia operations, various
Age and sex, particularly brain surgery patient.
The clinical effectiveness reached of the present invention is as follows：
1）Reduce operations on cranium and brain extubation choke intracranial pressure caused by cough drastically raise, bleeding, Brain shift；
2）Reduce stress caused by cardiovascular response, such as complication such as wound bleeding, cerebral hemorrhage, miocardial infarctions；
3）Surgical wound surface bleeding caused by preventing other operations；
4）Reduction cough of choking causes abdominal pressure to raise, wound dehiscence；
5）Prevent after anesthesia vomiting during apnea and emergence, inhale by mistake, glossoptosis.
Described above is the preferred embodiment of the present invention, can not limit the right model of the present invention with this certainly
Enclose, it is noted that for those skilled in the art, technical scheme is modified or waited
With replacing, without departure from the protection domain of technical solution of the present invention.
