Description

Tracheal intubation protection device Technical Field The invention relates to the technical field of medical equipment, in particular to a tracheal cannula protection device. Background Tracheal intubation is a key medical measure for maintaining the smooth airway and guaranteeing effective ventilation and oxygenation in the clinical anesthesia, intensive care and emergency treatment processes. The artificial airway is mainly used for bypassing upper respiratory obstruction or paralysis and directly conveying oxygen and anesthetic gas into the trachea and the lung, so that the respiratory function of a patient in the states of operation, respiratory failure, consciousness disturbance and the like is ensured. For general anesthesia operation patients, the tracheal intubation can realize the accurate control of mechanical ventilation, and for critical patients, the tracheal intubation is an important means for rescuing lives and preventing asphyxia. In clinical practice, the endotracheal tube must be firmly secured around the patient's face or mouth after the endotracheal tube is completed to prevent the tube from shifting or falling out during patient movement, coughing, vomiting or care operations. The fixing methods commonly used at present mainly comprise a ① adhesive tape or medical adhesive tape fixing method, a ② fixing strap (strap) method, a ③ commercial fixing device, such as an adhesive type fixer, a combination product of an occlusion blocking protector and a fixing splint, and the like, wherein the adhesive tape is used for fixing the guide tube and the bite block or the oral cavity angle, and then the adhesive tape is used for cross adhesion on two sides of the cheek, the cotton or elastic fixing strap is used for encircling the head and fastening the guide tube. Above-mentioned prior art's scheme exists that the assembly is loaded down with trivial details, functional unit is independent, protection continuity is poor, travelling comfort and security are not enough, urgent dismantlement and the inconvenient scheduling problem of adjustment, can lead to: The coupling degree of the anti-occlusion and anti-disengagement functions is low, the cooperative protection cannot be realized in the structure and the working principle, and the protection effect is unstable when the patient faces the sudden cough, agitation and other composite stress; Secondly, the assembly and adjustment process is complex, the time consumption is long under the condition that quick treatment is required, such as first aid or transportation, and the risk of unplanned tube drawing and ventilation interruption is increased; the multi-component superposition is easy to cause local compression, and long-time fixation can cause skin pressure sore or tape allergy, so that the comfort level and the skin safety of a patient are affected; The rigid connection among the parts is lacking, so that displacement or a protection blind area is easy to generate in use, and the catheter can still be damaged or fall off under the action of occlusion or pulling force; and fifthly, the operation is inconvenient when the cannula is pulled out or replaced in an emergency way, a plurality of parts are required to be detached in sequence, and the treatment opportunity is delayed. Disclosure of Invention The present invention aims to at least ameliorate one of the technical problems of the prior art. Therefore, the invention provides an endotracheal intubation protection device. The technical scheme of the invention is as follows: the utility model provides a trachea cannula protection device, wherein, includes integrated into one piece's anticreep pipe and pipe clamp, wherein, is located an arc wall has been seted up in the anticreep pipe lateral wall in order to communicate the line chamber of pipe clamp, the anticreep pipe has two protection units, is located arc wall both sides are in order to restrict its extraction when patient's oral cavity opens, and each protection unit includes: a main body part for being placed in the oral cavity of a patient, the surface of which is provided with a plurality of parts in sequence Each tooth socket is provided with a concave annular curved surface to form a tooth pad area for fitting teeth of a patient; when the patient applies force to bite, the thread cavity section of the pipe clamp can be switched from round to oval under the buffer effect of the bite block. In one possible technical solution, further, at least one tooth slot surface is provided with an auxiliary clamping slot, which is parallel to and offset from the arc slot, so as to facilitate the installation of the remaining catheters. The depth and the width of the auxiliary clamping groove are optimally designed, so that the external diameters of catheters with different models can be adapted, the catheters are ensured to be stably clamped in the auxiliary clamping groove, and the displacement or the escape of the catheters caused by the movem
