Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an endotracheal tube cuff air pressure monitoring device. Background Art

[0002] The establishment of an artificial advanced airway in critically ill patients is an effective means to ensure airway patency and plays an extremely important role in the rescue process. However, the establishment of an artificial advanced airway will also damage and destroy the body's normal physiological and anatomical functions to a certain extent. For critically ill patients who are in a sedated state or have impaired consciousness, the artificial advanced airway makes the patient's epiglottis semi-open, the glottis exposed, the swallowing function is inhibited, and the patient himself cannot expel oropharyngeal secretions from the body, resulting in oropharyngeal secretions or gastrointestinal reflux products being retained above the subglottic air bag. Most of the oropharyngeal and gastrointestinal reflux products contain a large number of bacteria, fungi and acidic substances. The endotracheal intubation catheter is equipped with an air bag structure, which plays the role of closing the airway and fixing the catheter, ensuring the supply of tidal volume, and preventing oropharyngeal secretions from entering the lungs, thereby reducing the occurrence of complications such as lung infection and tracheal injury.

[0003] At present, it is necessary to use a cuff pressure gauge to monitor the pressure of the cuff clinically so that the pressure inside the cuff is within the normal range, but the cuff pressure cannot be monitored in real time, so medical staff need to monitor it frequently, which means that the cuff needs to be replenished with gas at any time to maintain the target pressure within the normal range. The operation is cumbersome and increases the workload. Therefore, in order to solve the above problems, we propose a tracheal intubation cuff pressure monitoring device. Utility Model Content

[0004] The utility model aims to solve the defects in the prior art and proposes a tracheal tube cuff air pressure monitoring device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A tracheal tube cuff air pressure monitoring device comprises a tube body, a cuff is fixedly connected to the outer side of one end of the tube body, an inflation tube is fixedly connected to the outer side of the other end of the tube body, one end of the inflation tube passes through the tube body and is connected to the cuff, and one end of the inflation tube is fixedly connected to a Luer connector, the outer side of one end of the Luer connector is connected to a Y-type tube, one end of the Y-type tube is connected to a three-way control valve, the other two ends of the three-way control valve are respectively connected to a first connecting tube and a second connecting tube, and one end of the first connecting tube is fixedly connected to a monitor.

[0007] Furthermore, the monitor includes a shell, a control board is fixedly connected to the interior of the shell, an air pressure sensor is fixedly connected to one end of the shell, one end of the air pressure sensor is connected to the first connecting pipe, and the air pressure sensor is electrically connected to the control board.

[0008] Furthermore, a buzzer, a display screen and an indicator light are fixedly connected to the top of the shell, and the buzzer, the display screen and the indicator light are all electrically connected to the control board.

[0009] Furthermore, a T-shaped joint is fixedly provided inside one end of the Y-shaped tube, a sealing plate is fixedly connected inside the T-shaped joint, a first through hole is opened on the surface of the sealing plate, and a screw cap is rotatably connected inside one end of the T-shaped joint, and a second through hole is opened on the surface of the screw cap.

[0010] Furthermore, a sealing ring is fixedly arranged between the outer wall of the screw cap and the inner wall of the T-shaped joint.

[0011] Compared with the prior art, the beneficial effect of the utility model is that the monitor set in the present application can monitor the pressure changes in the cuff in real time. By presetting the pressure value, when the pressure in the cuff is lower than this value, the buzzer and the indicator light will start to prompt the medical staff, and the medical staff does not need to repeatedly test the cuff pressure, thereby reducing the workload of the medical staff.
