Cannula and method for tracheotomy patient respiratory muscle exercise extubation

Abstract

A cannula and method for tracheotomy patient respiratory muscle exercise extubation are disclosed. The cannula comprises a cannula body. The cannula body comprises a cannula head (1) and a catheter (2) which is connected with the cannula head (1). The cannula head (1) is a three-way pipe, at one end of which is arranged a cannula cap (3). A catheter head (5) connected with the catheter (2) is arranged at another end of the cannula head (1). Another end of the cannula head (1) is a passage (6) connected with trachea incision position of a patient, and a channel (4) connected with an oxygen-supplying catheter is arranged on the catheter (2). During usage, volume of the whole cannula of the patient is increased step by step, namely dead space volume of the patient is increased, and the patient is enabled to gradually exercise endurance of the respiratory muscle. The cannula is removed and the trachea incision is sealed when the patient can breathe by bearing dead space volume load of about 150 ml so as to recover the physiological status. The method is simple and has high practical value. The method can truly evaluate whether the patient can realize real pipe-pulling, thereby success rate of rescue is improved, and the last procedure of rescuing the critical patient is completed, so that the patient can return to normal state.

Description

technical field [0001] The invention relates to the field of tracheotomy in the rescue of critically ill patients, in particular to a cannula and a method for extubation for extubation of respiratory muscles of patients with tracheotomy. Background technique [0002] The important content of rescue of critically ill patients is life support. There are many technologies for life support, the most important of which are respiratory support and circulation support. Respiratory support is necessary and the most important content of life support. Life support strives for the rescue of critically ill patients. After time has passed, when the organ functions are gradually restored, the final step is how to wean off the mechanical ventilation and remove the intubation at the tracheotomy site. Only when the last two steps are completed can the critically ill patient be truly rescued successfully. [0003] The weaning of mechanical ventilation has made great progress after more than 2...

AI Technical Summary

Problems solved by technology

[0011] (1) The patient's endurance was not well evaluated;

[0012] (2) The extubation indexes in the current study seem to have objective data for evaluation on the surface, but patients have difficulties in doing it, for example, how to measure the maximum inspiratory pressure and vital capacity is difficult
