Abstract
An endotracheal (10) tube which facilitates rapid intubation of the trachea, especially in situations where anatomical variation creates difficult intubating conditions, includes a portion that can be bent (34) during placement to control the position of the distal end (16) of the tube (10). The distal end (16) of the endotracheal tube (10) may be selectively curled or bent by a mechanism or fluid passage accessible from the proximal end (20) of the endotracheal tube (10). The endotracheal tube (10) provides for manipulation of the insertion end without occluding the lumen of the tube (10), to facilitate placement of the tube (10).
Description
Technical field
Present invention relates in general to a kind of endotracheal tube.More particularly, the present invention relates to a kind of have be designed to be easy to owing to anatomical structure variation, wound, and the like the caused endotracheal tube that is not easy to make the flexible portion that place that airway (air pipe inlet) inserts inserts airway of reason.
Background technology
Endotracheal tube comprises generally as gas passage, so that oxygen and anesthetic gases are directly supplied with patient's cylindrical conduit.Cylindrical conduit is beneficial to the open distal end of inserting conduit by the end of being formed with always, and it has the opening opposing near-end that formation can be connected with source of the gas.Typical endotracheal tube has inflatable band to be used to form the sealing with the outer wall of conduit in the outside of cylindrical conduit.(referring to the U.S. Patent number No.3 of Doherty, 460,541).Band is used for occlusion catheter, and it can protect trachea and pulmonary to avoid sucking impurity.Specifically, the material that can prevent food, impurity or digestive system enters pulmonary.Endotracheal tube is mainly used in surgical operation, simultaneously also through being usually used in the occasion of emergency room and Emergency Assistance.
In needing the surgical procedures of general anesthesia, owing to comprise the narcotic effect of anesthetics and/or anesthetic gases, patient always is in automatism.Patient's is of flaccid muscles simultaneously/and stiff, thus reduce patient to inserting the disgusting reaction that endotracheal tube produces.Laryngoscope is placed on patient's mouth.The blade of laryngoscope is used for side and promotes tongue, and the intubate operator applies power upwards for the laryngoscope handle, so that can see the anatomical structure of oral cavity and trachea.The concrete target area of endotracheal tube is a glottis, just the space between vocal cords and the air pipe inlet.The far-end of endotracheal tube inserts glottis, and is full of air in the inflatable band (air bag), thereby forms gas-tight seal between band wall and inner surface of trachea.Gas-tight seal can make oxygen and anesthetic gases directly be sent to be arranged in the gas passage below far-end and the air bag under the effect of normal pressure.
Patient's anatomical structure is very different, and can it be grouped into different classifications according to the intubate difficulty that may exist.The patient of glottis or target hole before having (vocal cords and the space of the higher position that is arranged in patient's neck) to the cervical region front, the insertion end of placing endotracheal tube by the gap may be very difficult, and possible, even occur dead owing to anoxia causes grievous injury.Though the careful assessment that anesthesiology expert or health care operator propose thinks very difficult, some situation still is unpredictable arriving, unless can see tracheal orifice and vocal cords clearly by laryngoscope and blade apparatus.When this happens, the operator must take away laryngoscope, the probe (stylette) (semirigid stilet) of metal or plastics is inserted the inner chamber of endotracheal tube, conduit and probe are bent to suitable shape, thereby help insertion end is placed on appropriate position, and as positioning and guiding.Similar to the shape of hockey stick, probe and endotracheal tube are carried out very little bending, the main body of endotracheal tube is remained unchanged.In case finished this work, another part thing that the operator will do is observed vocal cords and inlet exactly.The curved shape of insertion end helps increasing the chance of insertion end being passed tracheal orifice.For example, at the U.S. Patent number No.2 of Sanders, the early stage endotracheal tube that comprises deflectable stylet is illustrated in 458,305.
Though the method that adopts probe to be used for the insertion end of crooked endotracheal tube is extensive use of, this method also has many shortcomings.Guiding-tube bend is become appropriate shape, observe subsequently and insert passage, and then from the inner chamber of endotracheal tube, take away these steps a lot of valuable time of meeting waste in finishing the process of intubate of probe.For irrespirable unconscious patient, the time is the most valuable, particularly when filling thing in patient's the stomach, will increase the chance that sucks impurity.
Equally, after the trial step of having finished initial placement laryngoscope, always to use probe usually.In addition, because the probe that will use must be semirigid, can be easy to bending, in case crooked, shape also can keep.The damage that this inherent characteristic makes patient to cause in trachea owing to probe is in danger, and trachea also has hemorrhage possibility simultaneously.In the past, adopt probe may cause the damage of soft tissue perforation and vocal cords.
Also do not have in the existing apparatus successfully to realize so that endotracheal tube forms suitable shape, thereby successfully patient to be carried out intubate by abandoning using probe.
Now existing devices are designed to help endotracheal tube is placed in the target hole.For example, now be developed into and can have helped the laryngoscope that inserts.Yet these devices can not provide the mechanism of the flexibility that can control the insertion end of endotracheal tube own.
The U.S. Patent No. 4,685,457 of the U.S. Patent No. 4,589,410 of Miller, the U.S. Patent No. 4,150,676 of Jackson and Donenfeld respectively demonstrates along having at least one draught line on the wall of the length of conduit part.Obviously, because the compression of material structure applies tension force and causes in the conduit generation near the balloon positions place curling on draught line.Yet the end of conduit can be not crooked, and bending is distributed in along on the whole length of backguy.These devices do not use the catheter wall of hinge or spring type mechanism or distortion, equally do not adopt retaining mechanism yet.As a result, these existing apparatus can not make the end of conduit selectively move.In these existing apparatus, by can the most pulley mechanism of bending conduit, the main body of conduit can move, therefore because conduit moving in the oral cavity also can produce some problems.
Utilization comprises the U.S. Patent No. 5 of Umeda, 255,688 other devices in interior guiding-tube bend mechanism can be directly connected to the bendable endoscope that is used for bronchoscopy (bronchoscopy), the crooked end that it is included between two coils on the catheter wall can cause the sweep bending by the draught line on the pull catheter wall.The U.S. Patent No. 4 of Sosnowski, 911,148 can directly link to each other with minor diameter endoscope (diameter of 0.15mm or littler), and it is along having a series of radial slots that certain intervals is arranged on the length direction of conduit, and draught line passes the catheter wall of otch.During the draught line tension, cause that the conduit edge has the part bending of otch, thereby can cause the far-end bending.The U.S. Patent No. 5,304,131 of Paskar shows tremulous pulse or the venous duct that has along the weakening part of conduit one side.Weakening part is owing to the otch that passes catheter wall causes.The cable of the wall by being passed in otch one side can make the weakening part bending.In order to help to make weakening part recover original rectilinearity, weakening part can surround with spring, thereby can seal weakening part, and pipe box can cover spring and weakening part.
The U.S. Patent No. 4,353,358 of Emerson links to each other with softish S sigmoidoscope, and it has otch and the draught line similar to the patent of Sosnowski et al.Heimberger has shown the endoscope and the conduit of the flexible far-end that other has hinge fraction and draught line equally in the U.S. Patent No. 5,772,578 of et al and the U.S. Patent No. 5,448,989 of Heckele.The U.S. Patent No. 5,306,245 of Heaven has shown flexible tube, and it comprises the cut wall relative with the flexible rustless steel hinge with the draught line on the conduit wall of relative hinge.The part of dissecing to the major general is covered by the plastic material of outside.Vinyl cover equally also can cover draught line, also can cover the whole length of conduit simultaneously.Air bag can be added in the end of flexible portion.These devices do not comprise such as inaccessible air bag required in endotracheal tube.Though comprise an air bag in the patent of Heaven, it is in the end of flexible portion, and is used for cholangiography, is not for sealing duct.
These devices are not to operate in the mode of endotracheal tube in aforementioned two paragraphs.They can not be in conjunction with feature of the present invention, when the major part of conduit keeps its original shape, connects with the joint near the part of the conduit of insertion end.
Though endotracheal tube has had multiple change, innovation and development, but need can be only at the device of end bent, and have can temporary locking position mechanism.Such endotracheal tube will be vacateed another hand operated other device such as laryngoscope with a hand operated conduit easily.Equally, also can under the assistance that does not have lumen catheter, finish the work.
Summary of the invention
Endotracheal tube of the present invention has the far-end of being arranged to be inserted in the person's windpipe that can handle, and it does not need to adopt probe or other guiding device, but the end of conduit can be near glottis.Leading body keeps its original shape, but can make end of conduit distortion or crooked separately, and in the process of placing endotracheal tube, can remain on the desired position always.In the process of far-end bending, the inner chamber of endotracheal tube keeps clear, thereby can not block patient's trachea.Belong to the various designs of volume scope of the present invention by employing, combine, can make the far-end of conduit form required far-end curvature with one or more mechanisms that are used for the far-end of control lead.According to the specific embodiment that the present invention is exemplary, it comprises:
1) setting spring between far-end and leading body;
2) adopt ultrasound wave, heat, solvent processing or similar method,, thereby can increase the flexibility of this part so that change the molecular structure or the composition of the polymer of the part that forms the conduit of wanting crooked;
3) between far-end and leading body, adopt polymeric separator plates;
4) surround the part of wanting crooked with polymer springs; Or
5) between far-end that is with or without the support spring and leading body, provide zone thin, that otch or incision are arranged.
Above-mentioned all mechanisms can be applied to the outside of endotracheal tube, are combined in the wall of conduit, or are inserted in the inner chamber of conduit.Endotracheal tube of the present invention can design one equally and be applied to the controlling organization that is used to cause the mobile and temporary transient locking bending of end on the distal catheter.By adopting friction locking unit, single shaft locking, slide lock device, brakes or can realizing this function to the similar locking device of draught line co-operate with lock ring.This locked position allows the operator to have at least a hands to have time can handle other device.In it was preferably operated, one held endotracheal tube, used another manual operating laryngoscope simultaneously.After the curved end of conduit was inserted on its desired position, trigger mechanism was disengaged at an easy rate, and conduit can present its original shape.Preferably, be inaccessible conduit cavity to occur in conjunction with the endotracheal tube of feature of the present invention, thereby make the operator can carry out far-end control capitally, and realize trachea control fast.
