Abstract
The utility model discloses a laryngeal mask which is essentially composed of an air bag, a connecting part and an airway tube which are connected to each other; wherein, one end of the connecting part is fixedly connected with the airway tube, while the other end of the connecting part forms an air outlet; the internal chamber of the air bag is communicated with an inflation tube which is provided with a one-way valve. The laryngeal mask is characterized in that the air bag, which is connected with the connecting part into a whole, is of a ring-shaped sack-like structure; one side of the air bag deviating from the air outlet of the connecting part is formed by extending the outer circumference of the connecting part; while one side of the air bag close to the air outlet is fixedly connected with the connecting part. The air bag of the laryngeal mask only needs a mould for injection molding in the manufacturing process of the laryngeal mask, thereby greatly reducing the manufacturing cost, and lowering the risk of the laryngeal mask falling off when in use, and improving the safety.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, is specifically related to a kind of laryngeal mask that is used to set up respiration channel.
Background technology
In therapeutic process, when run into out of the count patient or autonomous respiration relatively the difficulty patient the time, the doctor need breathe to help them by setting up a new respiration channel.Traditional method just is to use tracheal intubation, tracheal intubation comprises an elongated airway, far-end at airway is provided with charging portion, when operation, the far-end of airway inserts through patient's oral cavity, pass through patient's throat and enter trachea, behind the location, charging portion expands so that the sealing of formation and inner surface of trachea.After this sealing is set up, help patient to breathe thereby promptly can connect respirator at the near-end of airway.
Though this method can help patient respiration effectively, still there is bigger defective in tracheal intubation.The major defect of tracheal intubation is difficult to suitably insert in the trachea exactly, it is a process that specification requirement is very high that tracheal intubation is accurately inserted in the trachea, even for unusual skilled people in the industry, also be difficult to guarantee fully the accuracy of insertion in operating process, thereby in the medical procedure of reality, also occurred because the inaccurate or untimely situation that causes patient death that tracheal intubation is inserted.In addition, tracheal intubation can cause the violent pain of patient during insertion, and this is owing to rub between tracheal intubation and patient's the internal and cause.And another problem of tracheal intubation is exactly to handle patient's head and neck when intubate is inserted, and requires patient's jaw open very big, and also there is bigger potential safety hazard in these operations to patient's health.
At the above-mentioned deficiency of tracheal intubation, a kind of new respiration channel device--laryngeal mask has appearred.Laryngeal mask adopts blind insert method to swallow insertion throat through patient and sets up respiration channel, and general operation person just can use through short-term cultivation, and is therefore also very suitable at first aid occasion.Because laryngeal mask airway device do not need to contact with the inner passage of trachea sensitivity, also do not need to use laryngoscope, so the degree of patient's irriate alleviates greatly, and the respiration channel significantly set up greater than tracheal intubation of the size of the respiration channel of being set up.Simultaneously, smaller during owing to insertion to position control actions such as patient's head, necks, also smaller to patient's injury.Because above-mentioned advantage, laryngeal mask application clinically more and more widely.
In the prior art, laryngeal mask is mainly by air bag, connecting portion and airway connect and compose, connecting portion one end is connected with gas source interface by airway, the other end constitutes the gas outlet, usually, because the requirement of dissect physiology position, be 25 °～40 ° angle between the tube chamber axis of gas outlet end face and airway, air bag is connected in the periphery of described gas outlet with the fixed angle identical with the gas outlet end face, its inner chamber is communicated with the gas tube that has check valve, wherein, air bag and connecting portion be machine-shaping respectively in the course of processing, air bag and connecting portion is bonded together such as glue by binding agent.Because air bag and connection tube machine-shaping respectively, need die sinking respectively, injection moulding, cause the processing cost of laryngeal mask higher, and manufacturing process more complicated, simultaneously, because by bonding connection, so just have the bonding insecure risk that comes off of causing between air bag and the connection tube, this is breakneck in medical procedure.
Summary of the invention
This utility model purpose provides a kind of laryngeal mask, by the improvement of structure, turns technology into, reduces cost of manufacture, and improves the reliability in using.
For achieving the above object, the technical solution adopted in the utility model is: one one kinds of laryngeal masks, mainly connect and compose by air bag, connecting portion and airway, connecting portion one end is fixedlyed connected with airway, the other end constitutes the gas outlet, and the inner chamber of air bag is communicated with the gas tube that has check valve, and described air bag is the annular cystic structures with the connecting portion one, the side that air bag deviates from the connecting portion gas outlet is made of circumferential extension of connecting portion outer wall, and a side of close gas outlet is adhesively fixed with connecting portion and is connected.
Above, described connecting portion is provided with the connection step on the outer wall of gas outlet end, and the inboard of air bag correspondence is provided with and is connected the bonding part that step shape cooperates, and is connected the step connection that is adhesively fixed on described bonding part and the described connecting portion.
On the further technical scheme, described and gas tube that the air bag inner chamber is communicated with closely the check valve place be provided with pilot balloon.
Further technical scheme is 25 °～40 ° angle between the gas outlet end face of described connecting portion and the tube chamber axis of airway, and described air bag is parallel to the end face setting of described gas outlet.
Further the described airway inwall of technical scheme is provided with strip reinforcement projection.
In the medical care precess process, at first will swallow through patient and insert throat less than the laryngeal mask of inflation, treat the laryngeal mask position plug correct after, by check valve from gas tube to airbag aeration, this moment airbag inflation, strut venturi, contact sealing, form a new respiration channel with the throat inwall, connecting portion one end is fixedlyed connected with airway, the other end constitutes the gas outlet, and the airway exit can be connected with respirator, and respirator just can help patient to breathe through the gas outlet of connecting portion by airway.
Because the technique scheme utilization, the advantage that this utility model compared with prior art has is:
1, since in this utility model air bag be annular cystic structures with the connecting portion one, air bag and connecting portion only need the mould promptly can injection mo(u)lding in manufacturing process, solved in the past laryngeal mask make in air bag need two moulds to distinguish the problem of injection mo(u)lding with connecting portion, greatly reduce the cost of manufacture of laryngeal mask.
2, because this utility model air bag and connecting portion integrative-structure, avoided effectively that air bag and connecting portion have reduced the risk that comes off of laryngeal mask by the bonding situation about in use coming off easily of generation afterwards of glue in the former laryngeal mask, improved safety.
