Description

A kind of shaping tracheal cannula guidewire

Technical field

The utility model relates to medical auxiliary tool technology field, specifically a kind of shaping tracheal cannula guidewire.

Background technique

Special tracheal catheter is known as trachea cannula through the technology of glottis insertion tracheae, which can be maintenance air passage Unobstructed, ventilation oxygen-supplying, respiratory tract attract and prevent accidentally inhale etc. provide optimal conditions, be clinical treatment and rescue during it is normal Use technology.Tracheal catheter is softer, and oral cavity to tracheae glottis is a bending channel, and tracheal catheter usually requires to lead in tracheal catheter The moulding and guidance of silk are lower to enter tracheae, and especially under the conditions of difficult tracheal intubation, the effect of seal wire is more important.It is existing The common tracheal cannula guidewire structure of clinic is by a relatively simple, and mono- shaping metal strip of Chang Wei can only be in trachea cannula premise Preceding moulding, but the moulding may not be the curved shape most useful for tracheal catheter insertion, often results in trachea cannula failure, also needs two Secondary moulding even moulding three times, to delay clinical treatment and rescue time.

Utility model content

The utility model aim is overcome the deficiencies in the prior art, makes improvement to existing tracheal cannula guidewire, adapts to Realistic development provides a kind of shaping tracheal cannula guidewire.

In order to achieve the above objectives, the technical solution adopted in the utility model is as follows:

A kind of shaping tracheal cannula guidewire, including conducting wire pole, lower push-rod and upper rod, the upper section of the conducting wire pole are one Hollow elongate pipeline, the lower section of the conducting wire pole is gradually curved in camber, and arc medial surface duct wall retains, arc lateral surface pipeline Wall missing；The lower push-rod is placed in the conducting wire pole, and the fixed push button once in the upper end of the lower push-rod, the lower push button is through institute The strip aperture for stating conducting wire pole top is placed in outside the conducting wire pole, and the lower end of the lower push-rod is slight arc, and after One end of rod in activity axis connection；The upper rod is arc, and premenstrual movable axis is fixed on described lead in the middle part of the upper rod The lower section front end of screw rod.

It further, further include baffle, the baffle is mounted on the conducting wire pole, can be moved up and down along the conducting wire pole And it is fixed.

Further, the main body of the conducting wire pole is optical fibre tube or stainless steel metal pipe.

Further, the upper section of the conducting wire pole is equipped with scale.

Further, the outer diameter of the conducting wire pole is 5mm.

The advantages of the utility model and good effect: in prior art basis, increasing can be in endotracheal intubation The functional structure of middle moulding can adjust the curved radian in tracheae front end according to the position of tracheae glottis, lead to be conducive to tracheae The insertion of pipe.

Detailed description of the invention

Fig. 1 is structural schematic diagram of the utility model in stand-by state；

Fig. 2 is structural schematic diagram of the utility model in use state；

Mark meaning is as follows in Fig. 1-2: 1- conducting wire pole, 2- lower push-rod, the upper rod of 3-, 4- baffle, push button under 5-, living after 6- Moving axis, movable axis before 7-.

Specific embodiment

It is necessary to understand that, "upper", "lower", "top", "bottom", "inner", "outside" etc. refer in the description of the present invention, The orientation or positional relationship shown is to be based on the orientation or positional relationship shown in the drawings, target only the utility model for ease of description It is described with simplifying, is not that indication or suggestion institute finger must have a particular orientation, be constructed and operated in a specific orientation, Therefore it should not be understood as limiting the present invention.

It elaborates with reference to the accompanying drawing to specific embodiment of the utility model.

A kind of shaping tracheal cannula guidewire, as shown in Figs. 1-2, including conducting wire pole 1, lower push-rod 2, upper rod 3 and baffle 4, the upper section of the conducting wire pole 1 is a hollow elongate pipeline, and the lower section of the conducting wire pole 1 is gradually curved in camber, and on the inside of arc Face duct wall retains, arc lateral surface duct wall missing；The lower push-rod 2 is placed in the conducting wire pole 1, the lower push-rod 2 it is upper End fixed once push button 5, the lower push button 5 are placed in outside the conducting wire pole 1 through a strip aperture on 1 top of conducting wire pole, The lower end of the lower push-rod 2 is slight arc, and movable axis 6 connects one end of upper rod 3 after；The upper rod 3 is arc, The premenstrual movable axis 7 in 3 middle part of upper rod is fixed on the lower section front end of the conducting wire pole 1；The baffle 4 prevents tracheae from leading for one Sliding device, can move up and down along the conducting wire pole 1, the fixed bit of baffle 4 is adjusted according to the length of tracheal catheter on pipe It sets；The main body of the conducting wire pole 1 is the stainless steel metal pipe that outer diameter is 5mm, and the upper section of the conducting wire pole 1 is equipped with scale.

The utility model is to be inserted by the special tracheae that conducting wire pole 1, the lower push-rod 2 with push button, upper rod 3 and baffle 4 form Pipe seal wire, it is simple and practical, in use, lower push button 5 is sliding in the top, tracheal catheter is then inserted into the seal wire front end, according to The length of tracheal catheter is no more than tracheal catheter front end as principle using seal wire front end, and fixed baffle 4 is to prevent tracheal catheter edge from leading Silk upward sliding.With laryngoscope exposure patient's glottis, the tracheal catheter with the utility model is placed in oral cavity, according to glottis position It sets, pushes lower push button 5 with thumb, 2 slide downward of lower push-rod, movable axis 6 triggers upper rod 3 upwards after, i.e., before seal wire End is triggered upwards, and achievees the purpose that change tracheal catheter radian to be directed at glottis.

Above-described embodiment is only the more excellent embodiment of the utility model, all according to the technical essence of the utility model pair Any simple modification, modification and alternate variation made for any of the above embodiments, are all within the scope of the technical scheme of the utility model.
