Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a tracheal pressure detection device. Background Art

[0002] Endotracheal intubation is an important rescue technique commonly used in anesthesia and emergency treatment. Long-term use of endotracheal intubation and mechanical ventilation is often used during surgical anesthesia and severe illness, and plays a vital role in maintaining patient breathing, saving lives, and reducing mortality. In general, when using an endotracheal tube, the cuff pressure is determined by the experience of medical staff by squeezing and inflating the cuff. The specified value of the cuff pressure is 20 to 30 cmHg. If it is too low, air leakage will occur, and if it is too high, it will cause damage to the patient's tracheal wall.

This utility model tracheal intubation device collects data, converts data, displays data, and provides an alarm function by using an electronic sensor. Although it solves the problem that pressure monitoring cannot be timely and effective, the following technical problems still remain unsolved:

[0004] First, although it replaces the existing finger pinching external indicator balloon method and effectively solves the problem that tracheal pressure cannot be monitored in real time, it still requires manual operation to use a syringe to inflate to stabilize the pressure, which increases the workload of medical staff;

[0005] 2. Manually operated syringe inflation cannot control the inflation volume well, and it is easy to inflate too much at one time and then deflate, resulting in large air pressure fluctuations. Utility Model Content

[0008] The beneficial effects of the utility model are as follows: the connector is connected to the intubation pipeline, and the air pressure in the intubation pipeline is detected in real time through the air pressure detection module; when the air pressure is too high, the air outlet valve is opened to release the pressure; when the air pressure is too low, the air pump is turned on to inflate and pressurize; when the tracheal pressure reaches a preset value, the air pump immediately stops inflating; the arrangement of the air pressure detection module, the air outlet valve and the air pump replaces the traditional method of adjusting the air pressure by a syringe or an air bag, which is more accurate, avoids errors in manual adjustment of the air pressure, avoids large air pressure fluctuations, and also reduces the workload of medical staff.

[0025] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0027] Connect the connector 2 to the intubation pipeline, and use the air pressure detection module 5 to detect the air pressure in the intubation pipeline in real time. When the air pressure is too high, open the air outlet valve 6 to release the pressure. When the air pressure is too low, open the air pump 4 to inflate and pressurize. When the tracheal pressure reaches a preset value, the air pump immediately stops inflating. The air pressure detection module 5, the air outlet valve 6 and the air pump 4 replace the traditional syringe and air bag to adjust the air pressure, which is more accurate, avoids the error when manually adjusting the air pressure, avoids large air pressure fluctuations, and also reduces the workload of medical staff;
