Abstract
The utility model discloses a detachable guiding optical wand for tracheal intubation, which comprises an optical wand guide core and a tracheal tube. The front end of the optical wand guide core is provided with a bulb; the tracheal tube is sleeved outside the optical wand guide core; a tracheal tube gasbag is arranged on the tracheal tube; and a switch is arranged on a battery case. The optical wand is characterized in that a fast-detached type power joint is arranged between the optical wand guide core and the battery case. The optical wand has the advantages that the optical wand is simple in structure, convenient to operate, little in resistance and easy to mold and change blind intubation direction, reduces the injury to mouths and pharynges, shortens intubation time, and improves intubation success rate as well as safety.
Description
Technical field
This utility model relates to tracheal intubation guiding optical wand, more specifically relates to a kind of detachable tracheal intubation guiding optical wand, and it is widely used in clinical anesthesia.
Background technology
The optical wand guidance tracheal intubation is a kind of training that is easy to, and grasps easily, and is effectively simple, less to patient's circulating effect, can be used for normal air flue, can be used for the tracheal intubation technology of difficult airway again.Optical wand be one plastic, provide the thin bar of guiding of light source by aneroid battery, its front end is smooth spherical in shape, uses as illumination.Before the intubate, optical wand is inserted endotracheal tube, exposed optical wand front end bulb.Glottis was inserted in tentative blind spy after the power supply of unlatching optical wand was lighted the front end bulb, can see the bright point of cherry red distinctness at cervical region ring first film place skin, and the prompting optical wand correctly inserts trachea, and the guiding of endotracheal tube frontlighting nose is entered in the trachea.Traditional optical wand stops because of battery compartment, must be inserted in endotracheal tube earlier, in the clinical anesthesia operation, often bigger because of the particularly interdental frictional force of endotracheal tube and patient oral cavity of optical wand overcoat, endotracheal tube and optical wand swimmingly can not slide when causing operating, be difficult for changing blind spy direction accurately and effectively, increased the endotracheal tube pressure bladder simultaneously and scratched the chance of gas leakage, also easily cause the damage of patient's pars oralis pharyngis by tooth.
Summary of the invention
The purpose of this utility model is to provide a kind of detachable tracheal intubation guiding optical wand, and is simple in structure, easy to operate, resistance is little, optical wand is easily moulding, the blind spy direction of malleable, reduce the damage of pars oralis pharyngis, shortened intubation time, improved successful intubation and safety.
To achieve these goals, this utility model adopts following technical measures:
A kind of detachable tracheal intubation guiding optical wand, it comprises that optical wand leads core, endotracheal tube, battery compartment, optical wand is led the core front end and is provided with bulb, optical wand is led core and is with endotracheal tube outward, the endotracheal tube air bag is arranged on the endotracheal tube, battery compartment is provided with switch, it is characterized in that: lead being provided with quick dismountable power connection between core and the battery compartment at optical wand.
This utility model is to be provided with quick dismountable power connection between core and the battery compartment traditional leading of optical wand of tracheal intubation guiding, makes it possess fast quick-detach and the reliable function of leading the core power supply that is connected.
The present invention compared with prior art has the following advantages and effect: need not to be inserted in earlier endotracheal tube when inserting optical wand, have that resistance is little, optical wand is easily moulding, the characteristics of the blind spy direction of malleable; Can reduce the damage of pars oralis pharyngis, shorten intubation time, reduce the endotracheal tube air bag and scratched the chance of gas leakage, improve successful intubation and safety by tooth.
Description of drawings
Fig. 1 is a kind of detachable tracheal intubation direct light bar structure sketch map.
Wherein: 1-optical wand is led core, 2-battery compartment, 3-quick dismountable power connection, 4-bulb, 5-switch, 6-endotracheal tube, 7-endotracheal tube air bag.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail:
According to Fig. 1 as can be known, a kind of detachable tracheal intubation guiding optical wand, it comprises that optical wand leads core 1, endotracheal tube 6, battery compartment 2, optical wand is led core 1 front end and is provided with bulb 4, and optical wand is led outside the core 1 and is with endotracheal tube 6, and endotracheal tube air bag 7 is arranged on the endotracheal tube 6, battery compartment 2 is provided with switch 5, it is characterized in that: lead being provided with quick dismountable power connection 3 between core 1 and the battery compartment 2 at optical wand, dismountable power connection 3 adopts rotary joint style or plug-in type fast, soon quick-detach or reliable the connection.
After connecting power supply, open switch 5, optical wand is led core 1 insert in the trachea, separate quick dismountable power connection 3 rapidly, take off battery compartment 2, again endotracheal tube 6 is led core 1 tail end from optical wand and be inserted in, lead core 1 guiding with optical wand and enter in the trachea, finish tracheal intubation.Owing to before inserting optical wand, needn't be inserted in endotracheal tube 6, only need to insert separately optical wand, have that resistance is little, optical wand is easily moulding, the characteristics of the blind spy direction of malleable, shorten intubation time, improve successful intubation and safety.
Claims (2)
