The long-term use of trachea cannula and mechanical ventilation is commonly used during operative anesthesia and severe diseases, and plays a vital role in maintaining the breath of patients, rescuing lives and reducing the fatality rate. Generally, when using a tracheal tube, the cuff pressure is determined by the experience of the medical practitioner by squeezing the inflated cuff. The specified value of the cuff pressure is 20-30cm Hg, the condition of air leakage can occur when the cuff pressure is too low, and the tracheal wall of a patient can be damaged when the cuff pressure is too high. Therefore, there is a need for a closed loop endotracheal tube cuff pressure monitoring and control system that is satisfactory for use by medical personnel.

Detailed Description
The utility model is further described below with reference to the accompanying drawings.
Example 1: the closed-loop endotracheal tube cuff pressure monitoring and regulating system shown in fig. 1 to 2 comprises a single chip microcomputer 1 and a regulating unit, wherein the single chip microcomputer 1 is connected to one end of a pressure measuring pipeline 7 through a pressure detecting module 4, the other end of the pressure measuring pipeline 7 is connected to an air charging and discharging port 12 of a cuff 10 of an endotracheal tube 9, the single chip microcomputer 1 is electrically connected to the regulating unit, the regulating unit contains a motor 5, the motor 5 is connected to an injector 6, and air in the injector 6 enters or is pumped out of the cuff 10 of the endotracheal tube 9 by pushing or pulling the injector 6.
The single chip microcomputer 1 is electrically connected with the display screen 2 and the control unit 3.
The injector 6 is communicated with a pressure measuring pipeline 7 through an inflation and deflation pipeline 11, and a three-way joint 8 is arranged at the joint of the pressure measuring pipeline 7 and the inflation and deflation pipeline 11.
When the automatic inflation device is used in concrete, the motor 5 is used for pushing the injector 6 to enable air in the injector 6 to enter the cuff 10 of the tracheal catheter 9 to realize the function of automatically inflating the cuff 10 of the tracheal catheter 9, and when the pressure of the cuff 10 reaches the set parameter (20-30 cmH)20) Then, automatically stopping; automatic air supplement: the pressure drop (below 20 cmH) in the cuff 10 of the endotracheal tube 9 is caused for various reasons20) Then, the single chip microcomputer 1 can control the motor 5 to push the injector 6 to inflate the cuff 10, so that the pressure of the cuff 10 is increased, and the phenomenon that the cuff 10 is too low to seal the trachea and the secretion enters the trachea and the lung to cause aspiration pneumonia is avoided; automatic pressure reduction: over-pressure (above 30 cmH) of tracheal catheter 9 cuff 1020) During the process, the single chip microcomputer 1 can control the motor 5 and pull the injector 6 to deflate the cuff 10, so that the pressure of the cuff 10 is reduced, and the mechanical damage of the tracheal mucosa caused by overlarge pressure is avoided.
Periodic reduction cuff10, pressure: for a patient using the tracheal catheter 9 for a long time, the program of the singlechip 1 can be set, the pressure of the cuff 10 is periodically reduced and increased according to the set interruption time, and the cuff 10 is prevented from pressing the tracheal mucosa for a long time to cause tissue mucosa necrosis. For example, at regular intervals, the singlechip 1 automatically controls the motor 5 to draw the syringe 6, and reduces the pressure of the cuff 10 to 10-15cmH20, lasting for several minutes, pushing the syringe 6 again, increasing the pressure of the cuff 10 to 20-30cmH20。
The utility model has simple structure and practicality, can effectively detect and regulate the pressure in the tracheal catheter 9, and meets the use requirements of medical personnel.
Having thus described the basic principles and principal features of the utility model, it will be appreciated by those skilled in the art that the utility model is not limited by the embodiments described above, which are given by way of illustration only, but that various changes and modifications may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims and their equivalents.
