Apparatus For The Measurement of Intra-Abdominal Pressure

The present invention relates to a device for measuring intra-abdominal pressure, and more particularly, by improving the structure for measuring intra-abdominal pressure in a patient, measuring the pressure in a closed state of an apparatus for injecting and measuring saline, a urethral catheter, and a urine bag, It relates to a device for measuring intra-abdominal pressure that automatically returns to the original state of urination after measurement and enables continuous automatic pressure measurement, eliminating the need for operation and minimizing the connection of external devices to prevent cross-infection.

In general, intra-abdominal pressure refers to the pressure within the abdominal cavity composed of the abdominal wall, diaphragm, and pelvis, and intra-abdominal pressure is affected by body weight, posture, abdominal muscle tension, and diaphragm movement.

Such intra-abdominal pressure maintains a constant pressure in a healthy state, but in the case of a patient who has undergone surgery or a seriously ill condition aggravated, from causes that occupy intra-abdominal space such as blood abdominal cavity, ascites, and intestinal obstruction, acidosis, sepsis, and administration of a large amount of fluid And there are intrinsic causes of edema, such as blood transfusions, and can be increased by various causes, such as crusts in burns, in the supine position, and external compression such as compression of the diaphragm by a ventilator.

This continuous increase in intra-abdominal pressure (IAP) causes, in addition to direct pressure on the vena cava and abdominal organs, an increase in intrathoracic and intracranial pressure, creating a systemic vicious cycle.

In other words, as the increase in intra-abdominal pressure decreases the blood flow supplied to the nervous system, circulatory system, respiratory system, digestive system, liver, and kidney, it causes organ dysfunction. are receiving

Therefore, intra-abdominal hypertension, which increases intra-abdominal pressure, causes not only hemodynamic deterioration but also organ failure in intensive care, increasing mortality, and is itself a target of treatment along with the underlying disease.

Intra-abdominal pressure is a common complication in the critically ill patients, especially in critical surgical patients, and itself causes other diseases and is an important obstacle to recovery of critically ill patients. In addition to the appropriate control of fluid and blood doses for prevention, therapeutic surgery to break the vicious cycle in the limit of conservative treatment should also be actively considered.

Accordingly, by measuring intra-abdominal pressure regularly, intra-abdominal pressure is continuously managed, and measures are taken according to the pressure, thereby increasing the recovery capacity of critically ill patients.

Conventional intra-abdominal pressure measurement is mainly used as a non-invasive test method to indirectly check intra-abdominal pressure by measuring intra-abdominal pressure through an intra-bladder catheter in patients with suspected intra-abdominal hypertension or celiac syndrome.

In the prior art intraperitoneal pressure measuring device, in a state in which the urethral catheter and the urine bag are blocked with a valve manually operated by the user, a sterile saline solution such as saline is injected with a needle syringe, and the pubis (joint pubis, symphysis) is pubis) to measure the pressure.

However, as the needle syringe is used, the occurrence of cross-contamination increases, the height of the pubis is not constant depending on the person, and even if the intra-abdominal pressure increases, it is difficult to measure the height at which the pressure is measured depending on the size and shape of the pubis. there was
