Description
Technical field
This utility model relates to technical field of medical instruments, is a kind of video laryngoscope system of the adjustable visual field.
Background technology
Tracheal intubation is the important means that guarantees that the patient respiration road is unimpeded, keep the confession of body oxygen.The application of oral trachea cannula when emergency call salving is very general.The emergency call salving critical patient reaches needs to use laryngoscope usually when carrying out tracheal intubation clinically.Existing video laryngoscope system comprises laryngoscope mirror body, miniature video camera system and picture reproducer three parts, laryngoscope mirror body is made up of laryngoscope handle and laryngoscope blade, the laryngoscope blade positioned inside has minisize pick-up head and light source, light source links to each other with power supply in the laryngoscope handle by power line, and minisize pick-up head links to each other with the video reception display device through video transmission line.During use laryngoscope blade is inserted in the patient oral cavity, the laryngoscope blade front end places the root of the tongue and epiglottis intersection, upwards mention laryngoscope and expose the bottleneck throat anatomical structure, under the illumination of light source, the bottleneck throat anatomical structure is obtained and is transferred to by picture pick-up device and forms image on the display screen, the operator can adjust the orientation that laryngoscope blade inserts according to the image that shows on the screen, appears glottis until provoking epiglottis.Utilize this video laryngoscope system, make usually tracheal intubation become smoothly, simple and accurately, can be used for many people and observe the consultation of doctors simultaneously or be used for teaching, training.
Yet because the minisize pick-up head and the light source of this system are fixed on the laryngoscope blade front end, the visual field can't be regulated and control, and when the position, the visual field that shows on the fluorescent screen after laryngoscope blade inserts is not good, just can not point out ideal intubate orientation, and this can bring difficulty to tracheal intubation.Moreover; though the head of laryngoscope blade has some radian that upwarps; but to be fixed radian can't regulate and control for it; the normal patient of only suitable bottleneck throat anatomical structure; and for as short neck; mandible recession; bucktooth; ccavum oropharygeum is narrow and small; high palatine arches; the upper jaw bone prolapse; jaw is stung in dislocation; mandibular bone hypertrophy hypertrophy; bottleneck throat anatomical structures such as epiglottis is long or excessive are unusual or because of disease; the difficult airway patient of the glottis difficult exposure that reasons such as wound cause; difficult intubation even situation that can't intubate appear in regular meeting; not only bring misery, also can affect adversely and rescue or treatment opportunity to the patient.
Summary of the invention
The purpose of this utility model provides a kind of visual field regulatable video laryngoscope system, and its minisize pick-up head and light source are can be within the specific limits movable, so that the best smooth intubate in insertion orientation is sought in the regulation and control visual field when advancing mirror; Another purpose of the present utility model is to make the head of laryngoscope blade can be movable, the radian of adjustable laryngoscope blade head, so that the different adjustment flexibility according to difficult airway patient bottleneck throat anatomical structure when advancing mirror exposes glottis, thereby improve the success rate of tracheal intubation.
This utility model comprises laryngoscope mirror body, miniature video camera system and picture reproducer three parts, laryngoscope mirror body is made up of laryngoscope handle and laryngoscope blade, the laryngoscope blade positioned inside has minisize pick-up head and light source, light source links to each other with power supply in the laryngoscope handle by power line, and minisize pick-up head links to each other with the video reception display device through video transmission line.One of feature of the present utility model is also to comprise the movable adjusting rod of laryngoscope blade head.Laryngoscope blade is divided into body and head two parts, and the laryngoscope blade head is like triangle, and the laryngoscope blade body is fixed in by rotating shaft in the last angle on itself and the adjacent one side of laryngoscope blade body; Adjusting rod is made up of regulating arm and draw bar, the head of regulating arm in the form of sheets, one jiao of afterbody that is fixed in laryngoscope blade by rotating shaft of far-end, can rotate for opening and closing with respect to the laryngoscope handle, one jiao of near-end is fixed in an end of draw bar by rotating shaft, and the other end of draw bar is fixed in the inferior horn of laryngoscope blade head by rotating shaft.When regulating arm rotates for opening and closing with respect to the laryngoscope handle, the push-and-pull draw bar makes the laryngoscope blade head flexibility of rotational transform laryngoscope blade head up and down, and this can make the laryngoscope blade head upwarp when the difficult airway patient is implemented intubate, so that further provoke the root of the tongue and epiglottis portion, expose glottis better.Two of feature of the present utility model is also to comprise the visual field actuator of minisize pick-up head, it is made up of control valve, draught line, pulley and spring leaf, control valve is fixed in the afterbody of laryngoscope handle, pulley is fixed in laryngoscope handle and laryngoscope blade intersection, spring leaf is fixed in the angle between laryngoscope blade body and the minisize pick-up head, draught line turns round through pulley from control valve along the laryngoscope handle and links to each other with the minisize pick-up head afterbody, when pressing control valve pulling draught line, draught line pulling minisize pick-up head tail end rotates along fixed rotating shaft, thereby reaches the purpose of regulating the shooting visual field.
This utility model is by the visual field actuator of minisize pick-up head, the adjustable shooting visual field; The flexibility of the movable adjusting rod scalable laryngoscope blade head by the laryngoscope blade head, thus become easily when making tracheal intubation particularly implement intubate to the difficult airway patient, help alleviating the patient suffering and in time give treatment to.
