Improved visual trachea cannula

Abstract

The invention provides a visual trachea cannula. The cannula comprises a cannula body and a cuff. The cannula body comprises a flexible patient end, a machine end and a cannula cavity extended from the patient end to the machine end. The cuff is installed at the flexible patient end, and connected with an inflating device. The cannula body is provided with a bevel opening. The inner wall of the cannula body extended along the near end of the bevel opening is provided with an accommodating cavity and a washing channel. The opening end of the accommodating cavity is aligned to the near end of the bevel opening. The washing channel is adjacent to and separated from the accommodating cavity. A camera device is installed in the accommodating cavity. The camera device is inwards retracted relative to the near end of the bevel opening. The washing channel is provided with a washing hole which faces to the camera device and is communicated with the accommodating cavity. The flexible advantageof the flexible patient end is reserved, and the visual effect is achieved. In addition, the effect of cleaning a camera is remarkable.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an improved visible tracheal intubation tube. Background technique [0002] Endotracheal intubation is an important method often used in general anesthesia, cardiopulmonary resuscitation, and rescue of critically ill patients with respiratory dysfunction. The success rate of difficult airway intubation. The use of ordinary tracheal intubation requires the use of intubation light sticks or laryngoscopes and other medical instruments. , the laryngoscope and the light rod do great damage to the human body, and cannot achieve the visualization effect, and the visual laryngoscope can only observe the oral cavity and the glottis, and cannot fully achieve the visual effect, and the operation is time-consuming and costly; therefore, providing A visual tracheal intubation tube that is accurate and fast in operation, safe and effective in use, has little damage to huma...

[0002] Endotracheal intubation is an important method often used in general anesthesia, cardiopulmonary resuscitation, and rescue of critically ill patients with respiratory dysfunction. The success rate of difficult airway intubation. The use of ordinary tracheal intubation requires the use of intubation light sticks or laryngoscopes and other medical instruments. , the laryngoscope and the light rod do great damage to the human body, and cannot achieve the visualization effect, and the visual laryngoscope can only observe the oral cavity and the glottis, and cannot fully achieve the visual effect, and the operation is time-consuming and costly; therefore, providing A visual tracheal intubation tube with precise and fast operation, safe and effective use, little damage to human tissue, and dynamic video monitoring during the whole process is very necessary

[0003] CN205683368U discloses a visual tracheal intubation, in which a camera is arranged on the front end of the arc-shaped tube body. In current medical treatment, intubation guides made of soft materials are generally used to avoid trauma to the patient during the intubation process, but Installing a camera on the front end makes the socket hard, which weakens or even eliminates the advantages of a soft socket, making it difficult to popularize; at the same time, secretions from the oral cavity and esophagus will inevitably contaminate the camera during intubation, making it difficult to achieve a visual effect
