Abstract

The utility model provides a direct laryngoscope, which comprises a handle, a leaf fixed on the handle with an arc guide plate, and a light source arranged on the leaf. The light resource can be cold light source introduced by optical fiber, or direct hot light source. The utility model is characterized in that visual beam optical fiber is provided with an inlet close to the leaf of the light source and an outlet extending to the outsider of the leaf. Compared with current technology, the utility model can help doctors put tracheal catheters into patients rapidly and precisely while observing glottis, especially for some dangerous patients who can not move heads and necks, with the advantage of multifunction.

Description

A kind of direct laryngoscope

Technical field:

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of laryngoscope.

Background technology:

Existing direct laryngoscope mainly by handle, be fixed in the blade that has arc-shaped guide plate on the handle, the light source that is arranged on the blade constitutes, employing optical fibers that light source has imports cold light source, the employing direct heat light source that has.During work, blade inserted in the disease population by arc-shaped guide plate and blade open sight line passage and illuminate trachea glottis position, patient is practiced artificial respiration to make things convenient for doctor's direct observation trachea glottis and endotracheal tube accurately inserted in the trachea by light source from mouth to the trachea glottis.It is effectively that this kind direct laryngoscope is used in general patient, but not allowing critical patient's (as incidence wound, cervical vertebra postoperative, distortion of neck jaw portion etc.) of incidence position change to depend merely on direct laryngoscope for part just can not insert endotracheal tube in the patient's trachea rapidly, exactly, often need just can finish by the guiding of endoscopies such as branchofiberoscope or fiberoptic laryngoscope, this has just prolonged the effective time that gives emergency treatment to a patient, and has reduced the success rate that the critical patient rescues.In addition, insert in the trachea in the process of endotracheal tube because endotracheal tube has stopped the sight line passage, the doctor can only rely on before the intubate observed valve direction by rule of thumb, feel inserts endotracheal tube in the trachea, like this, just keeps away the appearance that unavoidable endotracheal tube misplugs the phenomenon of esophagus.

Summary of the invention:

Goal of the invention of the present utility model is to provide a kind of and need not just can helps the doctor seeing that glottis inserts endotracheal tube patient rapidly, exactly by the guiding of endoscopies such as branchofiberoscope or fiberoptic laryngoscope, and particularly part does not allow the endotracheal direct laryngoscope of critical patient of incidence position change.

This utility model is to realize like this, comprise handle, be fixed in the blade that has arc-shaped guide plate on the handle, be arranged on the light source on the blade, light source can be that optical fibers imports cold light source, it also can be the direct heat light source, its special feature is also to be provided with looks the light beam optical fibers, look on the blade of the fibre-optic light entrance of light beam place near the light source place, look the outlet of light beam photoconduction fiber optic line and be drawn out to outside the blade.During work, blade of the present utility model is inserted in patient's the oral cavity, intraoral throat profile sight line is delivered to and looks light beam photoconduction fiber outlet place outside the blade by looking light beam photoconduction transmitting fiber tow under the irradiation of blade light source, the doctor just can clearly observe throat in the patient's mouth by looking light beam photoconduction fiber outlet, like this, just make the doctor see that glottis accurately promptly is inserted into endotracheal tube in the trachea at an easy rate.Owing to adopted and looked the light beam optical fibers, therefore, this utility model also can be used as endoscope and uses.

Here, be securely fixed on the blade, on blade, be fixed with metal catheter in order to look the light beam optical fibers, the import of conduit is near the light source place, the outlet of conduit is provided with eyepiece, looks the light beam optical fibers and places in the conduit, looks the fibre-optic outlet of light beam and is connected with eyepiece.

In order to enlarge the scope that the light beam optical fibers is observed things of looking, it is to rotate to be actively socketed on to be provided with to look on the fibre-optic metal catheter person in charge of light beam that the fibre-optic metal catheter entrance point of light beam is looked in setting, loose joint one fork on handle is connected an interlinked mechanism between the fibre-optic metal catheter entrance point of light beam and fork are looked in setting.During use, fork on the swing handle, the interlock by interlinked mechanism pass to the oscillatory forces of fork to be provided with looks the fibre-optic metal catheter entrance point of light beam, and it is rotated in a small angle range, like this, just can enlarge the scope that the light beam optical fibers is observed things of looking.

Here, setting is looked in the fibre-optic metal catheter of light beam a conduit can be set, and the outlet of conduit passes outside the metal catheter of eyepiece end.Like this, by conduit, medicines such as anaesthetic can be expelled on the oral mucosa that blade arrives and carry out anaesthetic treatment.

This utility model compared with the prior art, owing to adopted and look the light beam optical fibers, therefore have and just can help the doctor seeing that glottis inserts endotracheal tube patient rapidly, exactly, does not particularly partly allow the critical patient of incidence position change endotracheal, has the advantage of multiple function of use by the guiding of endoscopies such as branchofiberoscope or fiberoptic laryngoscope.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of interlinked mechanism.

The specific embodiment:

Now in conjunction with the accompanying drawings and embodiments this utility model is described in further detail:

As shown in the figure, this utility model comprises handle 1, be fixed in the blade that has arc-shaped guide plate 23 on the handle 1, be arranged on the light source 4 on the blade 3, light source 4 adopts optical fibers to import cold light source, on blade 3, be provided with light source metal catheter 5, optical fibers 6 is fixed in the light source metal catheter 5, its special feature is also to be provided with looks light beam optical fibers 7, on blade 3, be fixed with metal catheter 8, the import 9 of conduit 8 is near light source 4 places, the outlet 10 of conduit 8 is provided with eyepiece 11, look light beam optical fibers 7 and place in the conduit 8, the outlet 12 of looking light beam optical fibers 7 is connected with eyepiece 11.

The metal catheter entrance point 9 that light beam optical fibers 7 is looked in setting is to rotate to be actively socketed on to be provided with on the metal catheter person in charge 8 who looks light beam optical fibers 7, loose joint one fork 14 on handle 1, the metal catheter entrance point 9 of looking light beam optical fibers 7 in setting is connected an interlinked mechanism 15 with 4 of forks.Here, the entrance point 13 of light source metal catheter 5 links together with the metal catheter entrance point 9 of looking light beam optical fibers 7 is set, and like this, the metal catheter entrance point 9 that light beam optical fibers 7 is looked in setting is under the direct irradiation of light source, and its visual field is clearly.

Setting is looked in the metal catheter 8 of light beam optical fibers 7 can be provided with a conduit 16, and the outlet 17 of conduit 16 passes outside the metal catheter 8 of eyepiece end.
