Description
Technical field
The present invention relates to medical instruments field, particularly relate to a kind of laryngeal mask breather.
Background technology
Assisted respiartion ventilation carries out assisted respiartion to keep the necessary means of General Anesthesia Undergoing hemodynamic stability when anaesthetizing sb. generally operation to surgical patient, and laryngeal mask airway is the usual way of assisted respiartion ventilation, and laryngeal mask is equipment necessary in laryngeal mask airway.
The popularization of laryngeal mask and use are intubation difficulties in order to overcome tracheal intubation ventilating mode and easily cause the shortcomings such as sensitivity response, realize the aeration of simple and convenient and the infringement of lowering patient's laryngopharynx and respiratory mucosa.Prior art has disclosed the basic structure of laryngeal mask, mainly comprises the assemblies such as cover body, breather, drainage tube, bite-block, aerating device and joint.The structure of cover body is the key of laryngeal mask, in prior art, cover body is formed by independent parts glue adhesions such as cover, cover inner drainage tube and cuff seal parts, due to the complex structure of cover capsule, parts make and adhesion technique all very complicated, production efficiency is low, and easily leave out-of-flatness burr, in use procedure, still stimulation can be caused even to damage to the pharyngolaryngeal mucosa of patient.
Publication number be CN101208125B in first patent of invention, disclose a kind of laryngeal mask airway devices and manufacture method, the cover agent structure of this patent to laryngeal mask is before optimized, and processing technology is also corresponding to be improved: be adhered to the sealing member described cover body being formed cover body after cuff blow molding.This design, by originally being reduced to by two adhering components molding molded separately by the cover body that lamellar multi-part glue is bonding, greatly reduces cover body out-of-flatness burr, simplifies processing technology simultaneously.But the cover body that the method makes at least also exists the bonding operation of one glue, and may produce out-of-flatness burr, molded and assembly technology can also simplify, and realizes more excellent laryngeal mask performance simultaneously.
Publication number be the U.S. of US7806119 (B2) prior patent disclose a kind of need not the airway management device of inflatable cover capsule, the cover body that the elastomeric material of given shape Shore hardness between 0-30 formed is made by a monoblock, this cover body need not be inflated, the sealing to throat is formed by prefabricated shape and soft elastomer, can insert fast although this structure need not be inflated, but due to being limited in scope of elastomer contracts, have much room for improvement to the sealing property of throat, material cost is also higher.
Summary of the invention
The object of this invention is to provide a kind of laryngeal mask breather, without the need to inflation, external diameter is less, can reduce the stimulation to throat's mucosa, and improves sealing and ventilation efficiency.
For achieving the above object, the invention provides a kind of laryngeal mask breather, comprise hollow cover body and connection tube, described hollow cover body comprises the cover portion of bottom opening and is positioned at the top in cover portion and supports the back in cover portion, the far-end at described back is provided with the connecting hole be connected with the near-end of connection tube, described cover portion is flexible annular flake structure, and described back is the supporting construction harder relative to cover portion.
As a further improvement on the present invention, the end face at described back and the bottom opening plane in cover portion form " V " shape acuter angles.
Further improve as of the present invention, described annular flake is bearing of trend is the vertical structure of container with opening.
Further improve as of the present invention, described annular flake is bearing of trend is the cambered structure of container with opening of inside shape.
Further improve as of the present invention, the lower limb of described annular flake extends to form hermetically-sealed construction.
Further improve as of the present invention, the bearing of trend of described hermetically-sealed construction is inside outside or vertical.
As a further improvement on the present invention, the end face at described back is all or part of smooth.
As a further improvement on the present invention, stomach esophagus drainage tube is provided with in described hollow cover body.
Further improve as of the present invention, described connection tube has multiple tract to be connected with hollow cover body respectively, and one of them tract of described connection tube is connected with stomach esophagus drainage tube.
As a further improvement on the present invention, described connection tube has a tract to be connected with hollow cover body.
Compared with prior art, the beneficial effect of laryngeal mask breather of the present invention is as follows:
(1) the laryngeal mask breather of inflatable cover capsule is in contrast to, owing to not having aerating gasbag structure: quick insertion can be realized and extract operation, need not inflate and bleed air operation, for first-aid patients saves the valuable time; Supporting syringe need not use, there will not be trachea to ventilate excessive and risk that is that break, also ventilation will be caused to leak due to air bag gas leakage; Be easier to industry manufacture, production cost is lower simultaneously; External diameter is less, less to the compressing of laryngeal tissue blood vessel, and protection throat mucosa, effectively alleviates the untoward reaction of Perioperative Patients.
(2) contrast adopts the cover body of flexible slabstock colloform texture, and be the cover portion of flexible annular flake structure due to what adopt, have better seal, decrease the amount that ventilation is leaked, ventilation efficiency is high; Effectively can collect the unnecessary mucus of throat's secretion, in the process of extracting breather, unnecessary mucus can be taken out, prevent mucus suck-back from entering air flue; Product structure is simpler, and product material cost is lower, has better performance simultaneously, is more conducive to commercial production; Support at harder back can adapt to the laryngeal structure of various different situation, ensure good sealing property simultaneously under coordinating, and just can realize the isolation of air flue and close by the opposing compression power of throat to back and cover portion.
(3) adopt smooth back designs, throat's physiological structure of more fitting, make back energy and throat's precision laminating, can effectively prevent from rotating and sliding, the safety that raising uses.
By following description also by reference to the accompanying drawings, the present invention will become more clear, and these accompanying drawings are for explaining embodiments of the invention.
