Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of drainage devices with bladder flushing and measure intra-abdominal pressure. BACKGROUND

[0002] Intra-abdominal pressure (IAP) refers to the steady-state pressure in the abdominal cavity, i.e., the pressure in the abdominal cavity resulting from the interaction between the abdominal wall and the internal organs. The intra-abdominal pressure of healthy adults ranges from 0 to 5 mmHg (1 mmHg = 0.133 kPa). Intra-abdominal hypertension (IAH) in critically ill patients is usually caused by fluid retention, abdominal surgery, and the use of respirators, etc., which often leads to an intra-abdominal pressure higher than the normal value, generally between 5 and 7 mmHg, and the intra-abdominal pressure continues to rise or repeatedly rises to more than 12 mmHg.

[0003] Abdominal hypertension can affect the respiratory function, circulatory function, renal function, and intestinal function of patients, causing a series of complications:

[0004] 1. Abdominal hypertension pushes the diaphragm to rise, reduces the capacity of the chest cavity, affects the lung ventilation and gas exchange function, and leads to respiratory distress and hypoxemia.

[0005] 2. Abdominal hypertension compresses the inferior vena cava, reduces the return blood volume, affects the cardiac output, and may lead to hypotension and insufficient tissue perfusion.

[0006] 3. Abdominal hypertension directly compresses the kidneys, reduces the renal blood flow and glomerular filtration rate, and leads to renal insufficiency and azotemia.

[0007] 4. Abdominal hypertension leads to reduced intestinal blood flow, intestinal wall edema, and impaired intestinal barrier function, which is prone to intestinal bacterial translocation and infection.

[0008] In order to avoid the above problems, the intra-abdominal pressure of patients in need is clinically measured through the bladder. The measurement of intra-abdominal pressure through the bladder is a standard technique recommended by the World Abdominal Compartment Syndrome Association.
