Specific embodiment

It should be noted that in the absence of conflict, the feature in the embodiments of the present invention and embodiment can To be combined with each other.

The utility model will be described in detail below with reference to the accompanying drawings and embodiments.

The present embodiment is related to a kind of guide device of endotracheal tube, as shown in Figure 1, guide device of endotracheal tube includes: internal formation There is the guiding tube 1 of airflow channel 103, the guiding tube 1 positioned at 103 one end of airflow channel constitutes trachea cannula inlet 101, is located at The guiding tube 1 of 103 other end of airflow channel constitutes oxygen supply end 102；Bracing wire 2 on guiding tube 1, external force is along guiding tube The crooked radian of guiding tube 1 can be changed in 1 axial tension bracing wire 2；And be removably connected to the oxygen supply end 102 of guiding tube 1 Standard breath return circuit joint 3；Further include the lip stopper 4 on guiding tube 1 close to oxygen supply end 102, and is set to guidance The air bag 5 of 1 periphery wall of pipe, air bag 5 are connected with gas-guide tube 6, and relative to one end that air bag 5 connects, the other end of gas-guide tube 6 is passed through It lip stopper 4 and is connect with sphygmomanometer inflatable ball 7.

In the present embodiment, the structure of guiding tube 1 is as shown in Figure 1 and Figure 2.For the ease of the conveying when trachea cannula operates Oxygen is formed with airflow channel 103 in the inside of guiding tube 1, has venthole in trachea cannula inlet 101, and shape is half Spherical shape, to prevent the damage in intubation to pharyngeal soft tissue；For the ease of being embedded in bracing wire 2, in 1 two opposite sides of guiding tube Form fluted 104；In order to be limited to guiding tube 1 is circumferential, to prevent guiding tube 1 from rotating, in guiding tube 1 periphery wall with The line vertical side of two grooves 104 is formed with symmetrical pillar embedding slot 105, on this pillar embedding slot 105 and following lip stoppers 4 Pillar 402 on 401 inner wall of guiding tube sliding eye cooperates.

In order to which guide device of endotracheal tube does not loosen in trachea cannula, in close trachea cannula inlet 101, in guiding tube 1 periphery wall forms air bag 5, is connected with gas-guide tube 6 with air bag 5, relative to the one end being connect with air bag 5, gas-guide tube 6 it is another The air guide pore 405 across following lip stoppers 4 is held, and is connect with sphygmomanometer inflatable ball 7, it, can by operating sphygmomanometer inflatable ball 7 The inflation/deflation to air bag 5 is realized, to adjust the gap between trachea cannula and guide device of endotracheal tube.

In the present embodiment, the structural schematic diagram of bracing wire 2 is as shown in Figure 4.In order to keep guiding tube bending curvature adjustable, this reality Bracing wire 2 there are two setting in example is applied, is flush-mounted in the groove 104 of 1 two opposite sides of guiding tube respectively, one end of bracing wire 2 is fixed on Trachea cannula inlet 101, the other end pass through following lip stoppers 4 and are connected with pull ring 201.Specifically, in also fixed in bracing wire 2 There is sliding block 202, in the boss 2021 for being formed with multiple consecutive intervals settings on sliding block 202, shape is hemispherical, for abutting Limited block 403 in following lip stoppers 4, so that hemispherical boss 2021 and boss embedding slot corresponding on limited block 403 4031 cooperations, thus fixed bracing wire 2.Along the axial drawing bracing wire 2 of guiding tube 1 when operation, to adjust the crooked radian of guiding tube 1, Drawing bracing wire 2 is longer, and crooked radian is bigger, operates the bracing wire 2 of symmetrical two sides, guiding tube 1 is made to be adjusted to suitable crooked radian, To be adapted with the pharyngeal anatomical structure of patient, to go on smoothly trachea cannula operation.

For the ease of passing through for guiding tube 1, in being formed with guiding tube sliding eye 401 in lip stopper 4, structural schematic diagram is such as Shown in Fig. 3, the pillar embedding slot formed with the periphery wall of above-mentioned guiding tube 1 is formed in 401 inner wall two sides of guiding tube sliding eye 105 corresponding pillars 402, pillar 402 and pillar embedding slot 105 cooperate, and limit thus circumferential to guiding tube 1, to prevent Only guiding tube 1 rotates.

Corresponding to the sliding block 202 in above-mentioned bracing wire 2, in being formed with mounting hole 406 in lip stopper 4, elasticity is installed thereon and is supported Splenium.In the present embodiment, this elastic pressure section includes elastic device, and with the elastic device be connected and because of the bullet The elastic force of property device and press on the limited block 403 in the bracing wire 2.Specifically, mounting hole 406 is through-hole, elastic device is excellent The spring 404 being selected as in mounting hole 406, in order to abut limited block 403 with the boss 2021 on above-mentioned sliding block 202, In forming the boss embedding slot 4031 with 2021 shape adaptation of boss on the side of limited block 403, relative to boss embedding slot 4031, the other side of limited block 403 and one end of spring 404 are connected.In order to make 404 elastic force of spring act on limited block 403 from And pressed slider 202, it is screwed on end cap 407 in the other end of spring 404, to control sliding block 202 in bracing wire 2 in limited block Sliding and locking in 403.In addition, air guide pore 405 is additionally provided in lip stopper 4, in order to which above-mentioned gas-guide tube 6 passes through.

For the ease of providing source of oxygen for airflow channel 103, the oxygen supply end 102 of guiding tube 1 has connection dismountable Standard breath return circuit joint 3, the oxygen supply end 102 of guiding device can also be connected with ventilator in the prior art.

In use, the air bag 5 is in a deflated state, guide device of endotracheal tube is inserted in trachea cannula, trachea cannula Inlet 101 is slightly longer than trachea cannula, while oxygen supply end 102 is connected source of oxygen, to a certain extent to the inflation of air bag 5 Afterwards, it is fitted close tracheal catheter and tracheal catheter guider, is not loosened.The tracheal catheter guider one of tracheal catheter will be housed Insertion patient throat is played, lip stopper 4 is blocked in the patient's mouth, tracheal catheter guider crooked radian is adjusted by drawing pull ring 201, To be adapted with the pharyngeal anatomical structure of patient, thus accurate intubation rapidly.

After the completion of trachea cannula operation, open the air valve 701 in sphygmomanometer inflatable ball 7, air bag 5 becomes smaller, trachea cannula with Gap between guide device of endotracheal tube becomes larger, to smoothly remove guide device of endotracheal tube.It is always patient in whole process Oxygen supply, particularly for the patient of difficult airway, trachea cannula difficulty increases, and needs the intubation of long period, no longer repeatedly The operation that tube drawing oxygen uptake is intubated again is carried out, to mitigate the damage to the pharyngeal soft tissue of patient, and timely logical for patient as early as possible Gas, as far as possible reduction patient's deaeration time.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection scope within.
