Abstract
The utility model discloses a movable double-tube laryngeal mask. The movable double-tube laryngeal mask comprises an air duct connecting pipe, a stomach guiding pipe placing channel, an air bag and an inflatable valve, a forward-tilting state of the air duct connecting pipe is changed to be a perpendicular state, the length of the air duct connecting pipe is shortened, and an inlet of the stomach guiding pipe placing channel is transferred to the side face of the laryngeal mask from the backside of the laryngeal mask. The movable double-tube laryngeal mask further comprises a bending connector, one end of the bending connector is connected with an air duct connecting pipe of the double-tube laryngeal mask, and the other end of the bending connector is connected with pipelines of a breathing machine. Due to the facts that the position of the inlet of the stomach guiding pipe is changed, the length of the laryngeal mask air duct connecting pipe is shortened, the connecting state of the laryngeal mask air duct connecting pipe is changed, and a bending connector is added, different positions which enable the pipelines of the breathing machine to be placed can be changed flexibly, surgical requirements of the head, the oropharynx, the upper limbs and the like are met, and safe and normal ventilation is ensured.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically, is a kind of movable two-tube laryngeal mask, and this laryngeal mask can satisfy the normal ventilation function of different position surgical patients.
Background technology
Laryngeal mask is a kind of novel breather, is different from the trachea ventilating mode, belongs on the glottis and ventilates.Do not need other devices to help just can to finish when its advantage is intubate, tissues such as damage tooth, oral cavity, vocal cords, trachea not, be applied to from 1988 clinical, for giving emergency treatment to a patient and maximum effect is brought into play in surgery anesthesia.Along with clinical needs, laryngeal mask also develops into the two-tube laryngeal mask of today from initial single tube.Find present two-tube laryngeal mask because the deficiency in the design can not satisfy clinical needs under different position conditions through a large amount of clinical practices.When positions such as upper limb, upper breast, cervical region, cranium brain undergo surgery, because the special construction of laryngeal mask and the interference of profile, add devices such as external breathing circuit filter, breathing circuit, had a strong impact on the exposure of operating field, can't undergo surgery, also influenced simultaneously the ventilatory function of laryngeal mask, had to clinically stop using laryngeal mask airway and use other ventilating modes instead and carry out surgery anesthesia.
The utility model content
The purpose of this utility model is at deficiency of the prior art, and a kind of movable two-tube laryngeal mask is provided.This novel movable two-tube laryngeal mask can comprehensive activity, guarantees that ventilation normally and not influences surgery anesthesia under the different position conditions of user.
For achieving the above object, the technical scheme taked of this utility model is:
A kind of movable two-tube laryngeal mask, comprise that air flue connection tube, stomach catheter insert passage, air bag and charge valve, described air flue connection tube is changed into plumbness and is shortened its length by forward-lean state, described stomach catheter is inserted the entrance of passage and is transferred to the side by the back side of laryngeal mask, described movable two-tube laryngeal mask also comprises curved joint, described curved joint one end connects the air flue connection tube of two-tube laryngeal mask, and the other end connects the respirator pipeline.
The length of described air flue connection tube shortens to 2.5cm by 4.5cm.
The angle of bend of described curved joint is 90 degree.
The length that described curved joint connects air flue connection pipe end is 4cm, and the port internal diameter is 1.5cm, and the length that curved joint connects respirator pipeline end is 4cm, and port outside diameter is 1.5cm.
This utility model advantage is:
The position of the movable two-tube laryngeal mask of this utility model by changing the stomach catheter entrance, shorten the length of laryngeal mask airway connection tube and change the laryngeal mask airway connection tube connection status, increase curved joint, can change diverse location flexibly and lay the respirator pipeline, satisfy the operation demand at positions such as head, pars oralis pharyngis, upper limb, guarantee that ventilation safety is normal.
Description of drawings
Accompanying drawing 1 is the structural representation of the movable two-tube laryngeal mask of this utility model.
Accompanying drawing 2 is the air flue connection tube of movable two-tube laryngeal mask and the left view that stomach catheter is inserted feeder connection.
The Reference numeral and the ingredient that relate in the accompanying drawing are as follows:
1. air flue connection tube 2. stomach catheter are inserted passage
21. stomach catheter is inserted feeder connection 22. stomach catheter and is inserted channel outlet
3. air bag 4. charge valves
5. curved joint 51. air flue connection tube links
52. respirator pipeline link
The specific embodiment
Below in conjunction with embodiment and with reference to accompanying drawing this utility model is further described.
Please refer to Fig. 1, Fig. 1 is the structural representation of the movable two-tube laryngeal mask of this utility model.This movable two-tube laryngeal mask comprises that air flue connection tube 1, stomach catheter insert passage 2, air bag 3, charge valve 4 and curved joint 5, and described stomach catheter is inserted the inside that passage 2 is positioned at two-tube laryngeal mask.
Described air flue connection tube 1 changes plumbness into by forward-lean state of the prior art, and its length is shortened to 2.5cm from 4.5cm, for the operation of positions such as cervical region, last breast provides good art open country.Stomach catheter is inserted feeder connection 21 and is transferred to the side by the back side of laryngeal mask, makes things convenient for inserting and fixing of stomach catheter, please refer to Fig. 2, and Fig. 2 is the air flue connection tube 1 of movable two-tube laryngeal mask and the left view that stomach catheter is inserted feeder connection 21.Stomach catheter is inserted the top that channel outlet 22 is positioned at air bag 3.
The angle of bend of described curved joint 5 is 90 degree, and its air flue connection tube link 51 is used for connecting the air flue connection tube 1 of two-tube laryngeal mask, and the length of this end is 4cm, and the port internal diameter is 1.5cm, can just be enclosed within air flue connection tube 1 outside; Respirator pipeline link 52 is used for connecting the respirator pipeline, and the length of this end is 4cm, and port outside diameter is 1.5cm, and convenient and corresponding pipeline is connected.This curved joint 5 is with after the air flue connection tube 1 of two-tube laryngeal mask is connected, and its respirator pipeline link 52 can rotate to different azimuth, and the convenient different directions of selecting is connected with the respirator pipeline, the interference of minimizing to performing the operation.
The position of the movable two-tube laryngeal mask of this utility model by changing the stomach catheter entrance, shorten the length of laryngeal mask airway connection tube and change the laryngeal mask airway connection tube connection status, increase curved joint, can change diverse location flexibly and lay the respirator pipeline, satisfy the operation demand at positions such as head, pars oralis pharyngis, upper limb, guarantee that ventilation safety is normal.
The above only is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from this utility model principle; can also make some improvement and replenish, these improvement and replenish and also should be considered as protection domain of the present utility model.
