Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a visualized tracheal intubation tube capable of adjusting air bag pressure. Background Art

[0002] The endotracheal tube is a medical device that is frequently used in hospitals. Endotracheal tube intubation refers to the technique of inserting a special tube into the trachea through the glottis. It can provide the best conditions for airway patency, ventilation and oxygen supply, respiratory suction and prevention of aspiration. It has become an important measure in the process of cardiopulmonary resuscitation and rescue of critically ill patients with respiratory dysfunction. It is one of the most widely used, effective and quickest means of respiratory management. According to the "Guidelines for Mechanical Ventilation" formulated by the Critical Care Medicine Branch of the Chinese Medical Association, it is recommended to maintain the pressure in the cuff of the artificial airway tube at 25-35cmH2O, which can not only maintain the positive pressure ventilation effect, but also prevent aspiration and complications such as airway damage caused by excessive cuff pressure.

[0003] The artificial airway catheter pressure measurement used clinically uses a balloon pressure detection gauge connected to the endotracheal tube balloon to directly detect the balloon body, which is easily contaminated, is not conducive to patient recovery, and reduces the service life of the balloon body. The lack of balloon pressure detection means that the pressure inside the balloon is observed based on previous experience of touching the airway indicator balloon, which is uncertain. At the same time, repeated manual measurement of the balloon pressure also adds a burden to the work. Utility Model Content

[0004] The utility model aims to provide a visualized endotracheal tube with adjustable air bag pressure to solve the technical problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the specific technical scheme of the utility model is as follows: a visual endotracheal tube with adjustable airbag pressure, comprising a catheter body, on which an airbag is arranged, an auxiliary piece passing through the bottom of the catheter body, and the auxiliary piece is provided with a three-way tube extending to the outside, the right end of the three-way tube is connected to a pressure detection gauge for checking the airbag pressure through a connecting tube, the left end of the three-way tube is connected to an inflated airbag through an inflation tube, and the middle end of the three-way tube is connected to a subglottic airway.

[0006] Preferably, the auxiliary sheet is made of silicone material, and the auxiliary sheet is arranged to fit the curve of the human neck.

[0007] Preferably, both end surfaces of the auxiliary piece are provided with through holes for passing laces.

[0008] Preferably, the pressure detection gauge is a rectangular structure, and is provided with three pressure zones of different colors, namely a white area, a green area and a red area, and a water column fluctuation is provided in the middle part of the surface of the pressure detection gauge along its length direction.

[0009] Preferably, the pressure value of the white area is 0-25 cmH20, the pressure value of the green area is 25-35 cmH20, and the pressure value of the red area is greater than 35 cmH20.

[0010] Preferably, the inflation tube and the inflated airbag are used to inflate the airbag, and a one-way deflation valve is provided on the inflation tube.

[0011] The utility model has the following advantages:

[0012] The utility model realizes real-time observation of the pressure value of the airbag by setting a pressure detection gauge, avoids the uncertainty of observing the pressure inside the airbag by touching the airway indicator airbag empirically in the past, and also avoids the workload of repeatedly manually measuring the pressure inside the airbag. When the real-time air pressure value is greater than 35cmH2O, the air is deflated through the one-way deflation valve. When the real-time air pressure value is less than 25cmH2O, the airbag is inflated by inflating the airbag and the inflation tube. The utility model can visualize the airbag pressure, has better pressure measurement execution, and is not easy to be contaminated, thereby reducing the pollution caused by directly detecting the airbag and complications such as endotracheal tube dislocation or airway injury caused by too low or too high endotracheal tube airbag pressure.
