The left end of the inflation channel 101 is communicated with an inflation tube 3, and a one-way inflation valve (not shown) is arranged on the inflation tube 3.
The right end of the endotracheal tube body 1 is provided with a pH sensor probe 4 and an inflatable airbag 5 which is horn-shaped after inflation, the inflatable airbag 5 is welded at the right end of the endotracheal tube body 1, and after the inflatable airbag 5 is inflated, the left end of the inflatable airbag 5 is thicker than the right end of the inflatable airbag 5. The inflatable air bag 5 is located above the plugging air bag 2, and as shown in fig. 2, the left end of the inflatable air bag 5 is communicated with a plurality of strip-shaped inflatable air bags 6, in the embodiment, the number of the strip-shaped inflatable air bags 6 is four, one strip-shaped inflatable air bag 6 is communicated with the inflation channel 101, the remaining three strip-shaped inflatable air bags 6 are welded with the endotracheal tube body 1, and two adjacent strip-shaped air bags are communicated.
Be equipped with pipeline II 102 in the pipe wall of endotracheal tube body 1, be equipped with signal transmission line 7 in pipeline II 102, the right-hand member and the pH sensor probe 4 electricity of signal transmission line 7 are connected, pH sensor probe 4 is located endotracheal tube body 1 in the right-hand member of inflation gasbag 5, the left end electricity of signal transmission line 7 is connected with signal processing display 8, is equipped with pH display module in the signal processing display 8, pH display module is used for showing the pH value that pH sensor probe 4 monitored. In this embodiment, the pH sensor probe 4 and the signal processing display 8 are well known to those skilled in the art and belong to the common knowledge, for example, the pH sensor probe 4 is a miniature pH sensor or pH electrode existing in clinical medicine, and the signal processing display 8 is a computer.
The specific implementation process is as follows: after the intubation of the tracheal catheter body 1 is completed, the inflation tube 3 inflates the inflation channel 101, so that the expansion airbag 5 and the plugging airbag 2 expand (increase in volume), and when the expansion airbag 5 is inflated, the inside of the strip-shaped inflation bag 6 is full of gas, therefore, the strip-shaped inflation bag 6 can support the left end of the expansion airbag 5 and extrude the left end of the expansion airbag 5, and the left end of the expansion airbag 5 and the tight attaching degree of the tracheal wall of a patient are improved.
After the inflatable air bag 5 is inflated, the left end of the inflatable air bag 5 is thicker than the right end of the inflatable air bag 5, so that after gastric contents such as gastric juice flow back into the trachea of a patient, the gastric contents such as gastric juice are intercepted by the inflatable air bag 5, the gastric contents such as gastric juice are prevented from flowing back to the plugging air bag 2, the gastric contents such as gastric juice are prevented from flowing back to the lung of the patient, and the lung of the patient is prevented from being damaged.
Meanwhile, gastric contents such as gastric juice are retained at the inflatable air bag 5, the pH sensor probe 4 monitors that the pH value is suddenly changed (the pH value in the trachea of a human body is within the range of 7.35-7.45, the pH value of the gastric juice is 1.3-1.8, the gastric juice is diluted after a meal, the pH value can be increased to 3.5, and the difference with the pH value in the trachea is still large, therefore, when the gastric contents such as the gastric juice are reflowed into the trachea, the pH value monitored by the pH sensor probe 4 is suddenly changed from 7.35-7.45 to below 3.5), and a medical staff observes that the pH value displayed on the signal processing display 8 is suddenly changed from 7.35-7.45 to below 3.5, which indicates that the patient reflows at the moment, the suction operation needs to be immediately carried out, and the gastric contents in the trachea of the patient are sucked out.
To sum up, the utility model discloses can utilize inflation gasbag 5 to hold back and flow back to gastric content such as gastric juice in the patient's trachea, utilize the pH value in the pH sensor probe 4 real-time supervision patient's trachea, in time discover that the patient takes place to flow back to in time take the operation of gastric content such as gastric juice in the suction patient's trachea, avoid patient's lung to inhale because of the mistake that flows back is impaired.
Example two
The difference between the present embodiment and the first embodiment is: as shown in fig. 3 and 4, a pipeline i is arranged in the tube wall of the endotracheal tube body 1, a suction tube 9 is arranged in the pipeline i, the suction tube 9 can extend out of the tube wall of the endotracheal tube body 1, and the extending position of the suction tube 9 is located on the endotracheal tube body 1 in the right end of the inflatable air bag 5.
In this scheme, accomplish endotracheal tube body 1's intubate after, in stomach content such as gastric juice refluxes to patient's trachea and is held back by inflation gasbag 5, the pH value sudden change is monitored to pH sensor probe 4, the pH value that shows on the signal processing display 8 is by 7.35-7.45 sudden change to below 3.5, medical personnel can aspirate stomach content such as gastric juice in patient's trachea through suction tube 9 immediately, need not additionally to carry out the intubate operation, convenient operation, timely.
EXAMPLE III
The present embodiment is different from the second embodiment in that: as shown in fig. 5, the signal processing display 8 is provided with an alarm 10, and when the pH sensor probe 4 detects a sudden change of the pH value, the alarm 10 gives an alarm. In this embodiment, the alarm 10 is a buzzer alarm in the prior art.
In the scheme, when the pH value displayed on the signal processing display 8 is suddenly changed from 7.35-7.45 to below 3.5, the alarm 10 gives an alarm to warn medical staff that the patient has reflux. Therefore, when the medical staff fails to observe the sudden change of the pH value displayed by the signal processing display 8 in the first time, the alarm 10 can ensure that the medical staff can find the patient to have reflux in the first time, so that the patient can be sucked in time.
Example four
The present embodiment is different from the third embodiment in that: as shown in fig. 6, the blocking balloon 2 at the right end of the endotracheal tube body 1 is removed. In the embodiment, the blocking air bag 2 is removed, and the expansion air bag 5 is directly inflated to block the trachea of the patient, so that the number of the air bags is reduced, and the expansion speed of the expansion air bag 5 is increased.
The above description is only an example of the present invention, and the detailed technical solutions and/or characteristics known in the solutions are not described too much here. It should be noted that, for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
