Abstract
The invention provides a trachea cannula guide device which is composed of a water injection connector (10), a water guide pipe (9), a handle (7), an adjusting rod (6), a guide device neck part (5), a bending part (3) and a guide device head end water bag (1). The adjusting rod (6) can control the direction of the guide device head end water bag (1) by pulling a steel wire (4) through a rotating shaft (8). The interior of the bending part (3) is connected through a bending snake skeleton (2) and is provided with the steel wire (4) capable of controlling bending of the bending snake skeleton (2). The guide device is arranged in a trachea catheter. The bending part (3) is exposed out of the catheter. The liquid is injected into the water injection connector (10) so that the guide device head end water bag (1) can be expanded. Under the guidance of the type-B ultrasonic, bending of the bending snake skeleton (2) can be controlled by holding the handle (7) of the guide device through the adjusting rod (6) and pulling the steel wire (4) through the rotating shaft (8), so that the guide device head end water bag (1) is made to be aligned with the glottis opening of a patient, the water in the water bag is pumped out, the guide device head end water bag (1) is contracted, and the trachea catheter is pushed into the trachea.
Description
Technical field: the present invention relates to a kind of guide device of endotracheal tube
Background technology: tracheal intubation is inserted in patient airway by endotracheal tube.It is widely used in medical rescue and surgery anesthesia.In every-day medical behavior, because endotracheal tube matter is soft, usually metal guide (also known as tube core) is placed in endotracheal tube in advance, the flexibility becoming to wish in order to auxiliary endotracheal tube, is more conducive to inserting in patient airway.This method has certain help for patient's (also known as difficult airway) that anatomical structure is special, but usually do not make doctor satisfied, because the sizing of this guide must be good with hands kneading before tracheal intubation, the guide taking-up of endotracheal tube and Qi Nei must be shaped again when finding when starting intubate to need to change guiding-tube bend angle, this obviously can increase the time of tracheal intubation, because now patient is anaesthetized by anaesthetic, can not breathe, patient can be made to be in the condition of life danger, to doctor with huge mental pressure.Simultaneously intubate increased frequency can increase the risk of pharyngeal soft tissue injury and the dislocation of trachea cartilage joint, meanwhile, if bled profusely in patient oral cavity, cannot visual cannulation, and current technology cannot ensure correct tracheal intubation, thus causes patient to rescue failed death.
Summary of the invention:
In order to overcome the deficiency of existing intubate guide, the invention provides a kind of guide device of endotracheal tube, this intubate guide can regulate the angle in endotracheal tube front at any time, makes difficult tracheal intubation become very simple.Pars oralis pharyngis soft tissue injury and the dislocation of trachea cartilage joint can be avoided to greatest extent simultaneously.The device of trachea front end can carry out intubate under ultrasound guidance.It is the state-of-the-art technology in the current world.
Technical scheme:
A kind of guide device of endotracheal tube, by water filling joint (10), aqueduct (9), handle (7), adjusting rod (6), guide cervical region (5), bending section (3), guide head end water pocket (1) forms.There is adjusting rod (6) at handle (7) place, can control guide head end water pocket (1) direction by turning cylinder (8) tractive steel wire (4).Bending section (3) is inner to be connected by bending snake bone (2), inside has steel wire (4) can control it and bends, outsourcing protecting film.Guide cervical region (5) is made up of hard not flexible metal or the synthetic material hollow pipe of fractureing of matter, innerly holds steel wire (4), top connecting handle (7), below connecting bending pars convoluta (3).
Accompanying drawing illustrates:
Accompanying drawing 1 is Product Status schematic diagram of the present invention;
1. guide head end 2. bends snake bone 3. bending section 4. steel wire 5. guide cervical region 6. adjusting rod 7. handle 8. turning cylinder 9. aqueduct 10. water filling joint
Detailed description of the invention:
Below by embodiment, and by reference to the accompanying drawings, structure of the present invention is further described.
First guide device of endotracheal tube is placed in endotracheal tube tube chamber, makes bending section (3) expose endotracheal tube.Liquid is injected to water filling joint (10), guide head end water pocket (1) is expanded, after B ultrasonic guides lower exposure patient glottis, hold guide device of endotracheal tube handle (7) by adjusting rod (6), bending snake bone (2) can be controlled by turning cylinder (8) tractive steel wire (4) to bend, guide head end water pocket (1) is made to aim at patient's glottis mouth, water pocket water is extracted out, guide head end water pocket (1) reduces, and easily endotracheal tube can be advanced the tracheal strips of patient.
Therefore, tool of the present invention has the following advantages:
1.B is super guides lower tracheal intubation to be the current up-to-date state-of-the-art technology in the world, and the present invention can make this technology be promoted.
2. this kind of method can make tracheal intubation once success, very convenient and safe.Difficult tracheal intubation is made to become very simple.
3. can dislocate at avoid pars oralis pharyngis soft tissue injury and the trachea cartilage joint of limit, reduce the generation of doctor-patient dispute.
Claims (3)
1. a guide device of endotracheal tube, by water filling joint (10), aqueduct (9), handle (7), adjusting rod (6), guide cervical region (5), bending section (3), guide head end water pocket (1) forms; There is adjusting rod (6) at handle (7) place, can control guide head end water pocket (1) direction by turning cylinder (8) tractive steel wire (4); Bending section (3) is inner to be connected by bending snake bone (2), inside has steel wire (4) can control it and bends, outsourcing protecting film.Guide cervical region (5) is made up of hard not flexible metal or the synthetic material hollow pipe of fractureing of matter, innerly holds steel wire (4), top connecting handle (7), below connecting bending pars convoluta (3).
2. a kind of guide device of endotracheal tube as claimed in claim 1, is characterized in that bending section (3) is inner and is connected by bending snake bone (2), inside has steel wire (4) can control it and bends, outsourcing protecting film.
3. a kind of guide device of endotracheal tube as claimed in claim 1, it is characterized in that guide head end water pocket (1) is for elastic hollow sacculus, be connected with aqueduct (9) down, by to water filling joint (10) water filling, guide head end water pocket (1) can be expanded, make to be a liquid cystic image under B ultrasonic, can know and guide guide direction.
