Abstract
The present invention relates to an endotracheal tube guide tube which comprises a fiber guide tube, and a lens barrel connected with one end of the fiber guide tube, wherein an eye lens, a cold light source joint, an anesthetic joint, an air pump joint and a turning button used for controlling the turning of the other end of the fiber guide tube; the end of the fiber guide tube is provided with a nozzle of a liquid spraying opening and a gas spraying opening which are respectively connected with the anesthetic joint and the air pump joint through a liquid circulation tube and a gas circulation tube which are arranged in the fiber guide tube. The endotracheal tube guide tube can be used by matching with various common gas circulation tube guide tubes with different diameters and different length; through the guiding of the optical fiber visual field of the guide tube, medical staff can accurately implement surface spraying type anaesthesia through pharynx, larynx and trachea mucosa; the endotracheal tube guide can be rapidly and accurately guided and inserted into the trachea; the present invention can avoid patient's secretion pollution the respiratory tract caused by zero range operation between medical staff and patients, and can bring great convenience for medical staff to implement tube insertion.
Description
Technical field
The present invention relates to medical apparatus and instruments, the endotracheal intubation guiding tube when being specially adapted to general anesthesia operation and rescuing the critical patient.
Background technology
Endotracheal tube generally is used for the patient of surgery anesthesia or respirator support, present endotracheal tube only is that length has only the 30-35cm pipe, when this endotracheal tube uses, must endotracheal tube could be inserted in the trachea by guiding tube, guiding tube in usefulness has two kinds now, a kind of is by laryngopharyngeal mirror endotracheal tube to be inserted in the trachea, if but run into the mandibular bone joint deformity, the patient of difficulty in opening mouth or cervical region cicatrix, because person's windpipe and mouth, pharyngeal anatomy relationship unusual, it is very difficult that endotracheal intubation will become, had a strong impact on carrying out smoothly and rescue fast and effectively of anesthesia, especially when rescuing some as patient SARS, closely intubate operation of medical personnel, very easily the saliva expectorant foam that is sprayed by the patient infects.Another kind utilizes the ordinary optic fibre bronchoscope as the endotracheal tube guiding tube, the ordinary optic fibre bronchoscope comprises fiber duct and is connected the lens barrel of fiber duct one end, on lens barrel, be provided with the button that turns to that eyepiece, cold light source joint, liquor joint and control fiber duct other end head turn to, this fibre optic bronchoscope is actual to be to be used for injecting liquid medicine in the biopsy pipeline, as the endotracheal tube guiding tube, owing to inject the non-spray form of anesthesia liquid, so effect is unsatisfactory.
Summary of the invention
The purpose of this invention is to provide a kind of energy convenience, successfully endotracheal tube inserted patient's trachea, the endotracheal tube guiding tube of avoiding the medical personnel to be polluted by patient's respiratory secretions.
Endotracheal tube guiding tube of the present invention is to be formed by the transformation of ordinary optic fibre bronchoscope, it comprises fiber duct and is connected the lens barrel of fiber duct one end, on lens barrel, be provided with eyepiece, the cold light source joint, anesthetis joint and control fiber duct other end head turn to turns to button, at lens barrel the air pump joint is set, the end fitting of fiber duct has the nozzle of mouth spray and puff prot, mouth spray and the puff prot fluid-through tube in being located at fiber duct respectively link to each other with the air pump joint with the anesthetis joint with breather, it is characterized in that this guiding tube disposes circular location elastic tape, it is porose to distribute on the anchor ring of elastic tape, the internal diameter of annulus cooperates with the external diameter of fiber duct, and the external diameter of annulus matches with the internal diameter of endotracheal tube.
When needs are implemented endotracheal intubation, endotracheal tube guiding tube of the present invention to be inserted in the endotracheal tube, the cold light source joint on the lens barrel connects cold light source, and the anesthetis joint links to each other with air pump with the micro-injection pump of air pump joint with the anesthesia sprayer unit.The medical worker is stretched to bottleneck throat with endotracheal tube lentamente under the guiding of endotracheal tube guiding tube, as run into the patient that mandibular joint deformity or cervical region cicatrix cause the neck movement inconvenience, the medical worker can be under the help in the optical fiber visual field, spray anesthetis simultaneously by the head position that turns to button to change guiding tube, anesthetis is the mist attitude and sprays to pharynx, larynx or tunica mucosa tracheae, can successfully endotracheal tube be inserted in the trachea, after finishing intubate, fixedly endotracheal tube is extracted the endotracheal tube guiding tube out, gets final product.
Endotracheal tube guiding tube of the present invention brings great convenience for the medical worker implements intubate, the medical worker under the guiding in the guiding tube optical fiber visual field by pharynx, larynx, tunica mucosa tracheae being implemented accurately the anesthesia of surface spray shape, can avoid the patient violent cough to take place effectively because of endotracheal tube stimulates larynx or tunica mucosa tracheae, endotracheal tube is guided in the insertion trachea rapidly, exactly, avoid the medical worker to be polluted by patient's respiratory secretions.This endotracheal tube guiding tube can with multiple different-diameter, the common endotracheal tube of different length is used, to make have enough distances between operator and patient, avoided using the auxiliary zero distance operation of carrying out tracheal intubation Shi doctor and patient of laryngopharyngeal mirror.
Description of drawings
Fig. 1 is the structural representation of endotracheal tube guiding tube;
Fig. 2 is the nozzle enlarged drawing;
Fig. 3 is a location elastic tape sketch map.
The specific embodiment
With reference to Fig. 1, endotracheal tube guiding tube of the present invention comprises fiber duct 1 and is connected the lens barrel 2 of fiber duct one end, on lens barrel, be provided with eyepiece 3, cold light source joint 4, anesthetis joint 7, air pump joint 5 and control fiber duct 1 other end head turn to turns to button 6, end fitting nozzle 10 at fiber duct, nozzle (seeing shown in Figure 2) has fixedly all-in-one-piece mouth spray 8 and puff prot 9, the injection direction of mouth spray 8 up, be positioned at the place ahead of puff prot 9 injection directions, mouth spray 8 and puff prot 9 fluid-through tube in being located at fiber duct 1 12 respectively link to each other with air pump joint 5 with anesthetis joint 7 with breather 11.
For endotracheal tube guiding tube of the present invention can be used with the common endotracheal tube of multiple different-diameter, this guiding tube also disposes and is used for and the localized circular location of endotracheal tube head elastic tape (see figure 3), it is porose 13 to distribute on the anchor ring of elastic tape, and the internal diameter of annulus and external diameter cooperate with the external diameter of fiber duct 1 and the internal diameter of endotracheal tube respectively.When the endotracheal tube caliber that uses when big (generally greater than 8mm), then can put corresponding header location elastic tape at the head of guiding tube.Like this, when about guiding tube or when moving up and down, can guarantee that endotracheal tube cooperates with guiding tube is synchronized with the movement, make endotracheal tube successfully insert patient's trachea, and the hole 13 that distributes on the elastic tape anchor ring can guarantee to use when locating elastic tape, is still had the air gap for patient respiratory between the endotracheal tube that guiding tube and quilt are inserted.
Use the endotracheal tube guiding tube, can make things convenient for, successfully the common endotracheal tube with various different lengths inserts in the patient's trachea.
