Abstract
A direct laryngoscope is provided comprising a handle, a blade fixed on the handle with an arc guide panel, and a light source on the blade. The light source can be a cold light source conducted via optical fibers, or a direct hot light source. Its special points also comprise visible beam optical fibers. Light inlet of the visible beam optical fibers is adjacent to the blade close to the light source, and above the end of the arc guide panel. A face slanted to the arc guide panel end is provided at the light inlet of the visible beam optical fibers, or a slanted face to conduct the light ray into the visible beam optical fibers. Light outlet of the visible beam optical fibers is conducted out of the blade. Compared with existing technologies, the utility model needs no guide with such endoscopes as fiber bronchoscope or fiber laryngoscope, etc, and a doctor can watch the glottis and quickly & accurately plug a trachea catheter into the patient body. The utility model especially makes for trachea for some critical patients whose position of head and neck cannot be changed. The utility model has the advantages of multiple functions of utilization.
Description
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 the fibre-optic light entrance of light beam place near on the blade at light source place and be positioned at the top of the termination of arc-shaped guide plate, look the fibre-optic light entrance of light beam and be provided with to import and look the fibre-optic inclined-plane of light beam, look the outlet of light beam photoconduction fiber optic line and be drawn out to outside the blade towards the inclined-plane of the termination of arc-shaped guide plate or with light.During work, blade of the present utility model is inserted in patient's the oral cavity, because looking the fibre-optic light entrance of light beam is provided with towards the inclined-plane of the termination of arc-shaped guide plate, intraoral throat profile sight line is delivered to looking light beam photoconduction fiber outlet place and be not subjected to stopping of arc-shaped guide plate 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 in order to look the light beam optical fibers, blade is provided with metal catheter, 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.
Use for convenience, be provided with the metal catheter seat on blade, metal catheter is arranged on the metal catheter seat.During use, if general common patient, can device have and look the fibre-optic metal catheter of light beam, if special patient, just metal catheter on the device.
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;
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, the 7a of light entrance place that looks light beam optical fibers 7 is near on the blade 3 at light source 4 places and be positioned at the top of the termination 2a of arc-shaped guide plate 2, the light entrance 7a that looks light beam optical fibers 7 is provided with and imports the inclined-plane of looking light beam optical fibers 7 towards the inclined-plane of the termination 2a of arc-shaped guide plate 2 or with light, also be provided 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, looking light beam optical fibers 7 places in the conduit 8, the outlet 12 of looking light beam optical fibers 7 is connected with eyepiece 11, be provided with metal catheter seat 13 on blade 3, metal catheter 8 is arranged on the metal catheter seat 13.
