Device for quickly positioning tracheal vessel by colorimetric method

Abstract

The invention discloses a device for quickly positioning a tracheal vessel by a colorimetric method, which comprises a breather pipe, an insert wall structure, a slot structure and a colorimetric wafer; the insert wall structure and the slot structure are in insert connection to form an integral tubular structure; the colorimetric wafer is formed by fixing two nylon meshes on an circular outer ring, and tissue paper dyed by blue lacmus solution is arranged between the two nylon meshes; and when the insert wall structure and the slot structure are in insert connection to form the integral tubular structure, circular objects protruding on the inner walls of the insert wall structure and the slot structure press against the colorimetric wafer to fix the colorimetric wafer. After an emergent tracheal vessel operation is carried out, the breather pipe is connected with the tracheal vessel and the like, and that whether the tracheal vessel is positioned in the trachea can be judged by utilizing a principle that the moist tissue paper after contacting carbon dioxide breathed out becomes red. The device has the advantages of low cost, simple and convenient operation, capacity of saving precious time for rescuing the patient during cardiopulmonary resuscitation, and wide application range.

Description

technical field [0001] The invention belongs to the field of medical technology application, in particular to a device capable of quickly judging whether a trachea tube is accurately positioned in the trachea. Background technique [0002] Endotracheal intubation is required when patients undergo general anesthesia or cardiopulmonary resuscitation in the emergency room. Because the opening of the trachea and esophagus are close, it is very easy to insert the endotracheal tube into the esophagus during tracheal intubation. At present, although it is possible to accurately determine whether the endotracheal tube is in the trachea by monitoring the end-tidal carbon dioxide waveform, the instrument for monitoring the carbon dioxide waveform is complex and not easy to carry, and has many limitations in practical application. Therefore, it is usually used in wards or emergency rescue rooms Instead of using the above-mentioned instruments, it is possible to determine whether the in...

At present, although it is possible to accurately determine whether the endotracheal tube is in the trachea by monitoring the end-tidal carbon dioxide waveform, the instrument for monitoring the carbon dioxide waveform is complex and not easy to carry, and has many limitations in practical application. Therefore, it is usually used in wards or emergency rescue rooms Instead of using the above-mentioned instruments, it is possible to determine whether the inserted endotracheal tube is in the trachea by seeing the tube entering the glottis during intubation, and then auscultating the breath sounds of both lungs. This method is sometimes difficult to judge the position of the endotracheal tube
