Description

A kind of esophagus closure is with combining air-breather on glottis

Technical field

The utility model is related to technical field of medical instruments, it particularly relates to which a kind of closure of esophagus is combined with glottis Air-breather.

Background technology

, it is necessary to which the patient of row mechanical ventilation, generally requires that tracheal catheter is inserted into tracheae by laryngoscope, build in clinical position Vertical artificial airway, can realize mechanical ventilation.In actual clinical work, artificial airway is set up by trachea cannula and realizes machinery Ventilation is remained in many problems.（1）Waste time and energy, stall for time during difficult intubation, it is impossible to which insertion tracheal catheter can be given and need in time The patient that promptly set up artificial airway brings danger.（2）Cumbersome complexity, is difficult to be unfamiliar with the medical matters people of this operation Member is grasped.（3）Need the special instruments such as laryngoscope, conduit.（4）Catheterization procedure, which has, causes oral mucosa damage, bleeding, tooth The risk of complication such as loosen, come off.（5）Intubation, tube drawing process stress reaction are strong, cause patients' blood's rise, heart rate to add It hurry up, it is big to the patient effect that has cardio cerebrovascular affection.（6）, not so can be because it is required that medical worker grasps preferably to Extubation indications Autonomous respiration do not reach standard but extubation and have difficulty in breathing.（7）In the full stomach patient of emergency treatment, intestinal obstruction patient Rescue and anaesthesia process in, can cause to backflow because of gastric content vomiting, inhale by mistake and airway obstruction produce danger.（8）Intubation Process usually requires to use anaesthetic, to solve the problem of haemodynamics fluctuation is violent, it is desirable to had using the doctor of medicine Certain qualification.（9）Intubation and conduit have certain damage using process to the mucous membrane of glottis, tracheae, may occur in which tissue edema There is dysventilation after tube drawing.（10）Model selection to conduit is stricter, particularly past in pediatric patient, but when specifically chosen It is past to depend on the calculating of experience and formula, it is impossible to estimate or try out to be selected, there is the probability of certain selection mistake, once There is such case to be changed, it is necessary to pull out the conduit inserted, cause secondary damage.

The method for clinically also having some other to set up artificial airway, such as inserts laryngeal mask, esophagus tracheae catheter for combining, but In place of equal Shortcomings, it is mainly manifested in：

First, trachea cannula needs special intubation instrument, and intubation technique is more difficult to be grasped.Intubation and tube drawing process haemodynamics Fluctuation is obvious, larger to gerontal patient and the patient effect for merging cardio-cerebrovascular disorder；

2nd, laryngeal mask conveniently has certain application value because inserting in Clinical practice, for the patient of difficult airway, uses Laryngeal mask can solve because difficult intubation bring the problem of.But laryngeal mask has the requirement of height for the selection of model, for using The less medical worker of experience, easily occurs selecting improperly situation.In addition, laryngeal mask can not solve the risk inhaled of backflowing, even by mistake This risk may be increased, for there is the dangerous patient of air draught by mistake of backflowing, it is not recommended that use；

3rd, esophagus tracheae catheter for combining can effectively block esophagus, and solution, which is backflowed, misses the problem of inhaling.But it is difficult in Clinical practice Place to correct position, as managed improperly during use, bulb displacement can cause asphyxia；Conduit is harder, and blind tracheal intubation is damaged The risk of wound pharyngeal and glottis.

Utility model content

For the above-mentioned technical problem in correlation technique, combine logical with glottis the utility model proposes a kind of closure of esophagus Device of air, it is intended to solve at least one problems of the prior art.

To realize above-mentioned technical purpose, what the technical solution of the utility model was realized in：

A kind of esophagus closure is with combining air-breather, including the medical respiratory masks fitted with human body nose and mouth on glottis With esophagus plugging device, it is provided with firm banking, the firm banking on the medical respiratory masks and is provided with mounting hole, institute State esophagus plugging device to insert the mounting hole and be connected with firm banking by fastening nut, the fastening nut and fixed bottom Preceding cutting ferrule and rear cutting ferrule are provided between seat.

Further, it is provided with external screw thread on the firm banking.

Further, it is provided with the internal thread matched with external screw thread on the fastening nut.

Further, it is provided with lung ventilator interface on the medical respiratory masks.

Further, it is provided with fixing band on the medical respiratory masks.

Further, it is provided with VELCRO in the fixing band.

The beneficial effects of the utility model：

（1）Conscientiously the scheme of difficult airway is solved, it is simple to operate, it is easy to left-hand seat；

（2）The design is ventilating technology on glottis, without row endotracheal intubation, disturbs small to patient airway；

（3）To tunica mucosa tracheae entirely without damage, Esophageal Mucosa will be significantly larger than tracheal mucosa to the tolerance of pressure；

（4）Multi-mode ventilate, can autonomous respiration and control breathing between free switching, it is to avoid because patient's mind recover There is man-machine confrontation, acutely choke and the reaction such as cough, patient can be with free switching between ventilating mode, and medical worker need to only exhale control Suction mode is converted to autonomous respiration mode, easy to operate without pulling out tracheal catheter or laryngeal mask etc.；

（5）Surgery needs are met, the problem of can solving to ventilate on gastrointestinal decompression and glottis simultaneously；

（6）By oropharyngeal airway, pars oralis pharyngis secretion can be attracted, ensure that air flue is dried, be not secretion institute Interference；

（7）Exempt the stimulation to patient for plugging and unplugging tracheal catheter, the patient for not being resistant to tracheal catheter is especially suitable for；

（8）Block oesophagus, it is to avoid backflow and inhale by mistake；

In summary, the utility model is convenient and easy in Clinical practice, it is adaptable to general patient with operation general anesthesia or rescue When control breathing use, be particularly suitable for use in difficult airway or full stomach patient；First aid need to control not require endotracheal intubation during breathing, Easily grasped for medical worker, improve rescue efficiency.
