Description

Noninvasive intra-abdominal pressure monitoring method, system and device

Technical Field

The present invention relates to the field of health monitoring technology, and in particular, to a non-invasive intra-abdominal pressure monitoring method, system, device, computer apparatus, and computer readable storage medium.

Background

Clinically, intra-abdominal hypertension is a critical sign that causes hypoperfusion of organ tissue, and persistent intra-abdominal hypertension with new organ failure develops into abdominal compartment syndrome, which in severe cases endangers patient life. Intra-abdominal hypertension is very common in patients after severe acute pancreatitis, burns, abdominal trauma, sepsis, abdominal surgery, and Intra-abdominal pressure (Intra-Abdominal Pressure, IAP) is often monitored. Thus, intra-abdominal pressure has become the sixth vital sign following body temperature, blood pressure, heart rate, respiration, and oxygen saturation.

There are many elements that cause an increase in intra-abdominal pressure, and when the volume of the abdominal cavity increases, the volume of the abdominal cavity decreases, and the compliance of the abdominal wall decreases, the intra-abdominal pressure increases. And the continuous rise of intra-abdominal pressure affects blood circulation, which causes great damage to most organs of the body. The adverse effects of high intra-abdominal pressure on the human body are several: (1) Excessive intra-abdominal pressure can cause compression on the intestines and stomach, thereby damaging gastrointestinal function, and can also cause multiple organ dysfunction syndrome; (2) As the intra-abdominal pressure increases, greater compression is generated on the vessels of the abdominal cavity and the thoracic cavity, thereby causing resistance of the vessels in the whole province, and simultaneously affecting the reflux of heart blood and the delivery of blood by the heart, so that the long-time intra-abdominal pressure affects the heart function; (3) High intra-abdominal pressure can have various adverse effects on various organs close to the abdomen. Because of the above-mentioned hazards, high levels of intra-abdominal pressure are an important cause of high morbidity and mortality in the course of occurrence and development of various severe diseases.

Sustained increases in Intra-abdominal pressure can lead to Intra-abdominal high pressure (Intra-Abdominal Hypertension, IAH); sustained, unrelieved IAH may develop into the ventricular compartment syndrome (Abdominal Compartment Syndrome, ACS). IAH and ACS have tremendous damage to tissues and organs of the gastrointestinal tract, heart, lung, kidney, etc., and patients may be associated with shock and risk of death. Among them, ACS is an acute process, and the abdominal wall cannot make compensatory adaptation to rapidly rising pressure, so that the pressure therein is continuously rising, and at the same time, cases such as organ failure and the like occur, and the death rate is high.

High levels of intra-abdominal pressure can cause significant damage to various organs of the body; when the intra-abdominal pressure is more than or equal to 25mmHg accompanied by organ dysfunction or organ failure, only the most effective treatment can be performed by using a laparotomy. Therefore, if intra-abdominal pressure can be monitored as early and accurately, there is an opportunity to decompress using other less damaging methods without requiring a laparotomy. There are various ways to help the patient reduce the intra-abdominal pressure when it is 15mmHg or less, so if we can find the sign of the increase in intra-abdominal pressure earlier, the more beneficial will be the subsequent treatment and the less harm will be done to the patient's body. For various patients who are subjected to abdominal operation and have conditions such as abdominal infection, abdominal bleeding and the like, IAH and ACS are possibly suffered, and for the patients, intra-abdominal pressure must be monitored in the treatment process so as to ensure that medical staff can grasp the conditions of the patients in real time. It was counted that IAH occurred up to 58.8% during ICU in-treatment; the incidence of ACS in surgical patients during treatment in the ICU is about 8.2%. Currently, monitoring but stress has evolved as an important means of determining whether IAH and ACS occur. Therefore, routine monitoring of intra-abdominal pressure within the ICU is necessary.

However, existing intra-abdominal pressure monitoring includes direct pressure measurement, cystometrography, girth measurement, abdominal wall tension measurement, and the like.

Direct pressure measurement, while capable of accurately measuring intra-abdominal pressure, can also lead to infection during operation, which can cause greater harm to the patient, because the method is an invasive test. In addition, in the actual operation, since the conditions in the abdominal cavity of many IAH patients are complicated, organs in the abdominal cavity may be injured during the epidermis puncture. Therefore, direct measurement cannot be generalized for use in conventional assays.

Compared to direct measurement, cystometrography does not require puncturing of the abdomen and therefore does not cause direct harm to the body. However, cystometrograms have some drawbacks: (1) Since a catheter is required to be placed in the bladder through the urethra, this approach can also cause some injury to the body and can also cause urinary tract infections while the procedure is in progress. Thus, cystometrography does not fully enable noninvasive monitoring; (2) When a patient has a tumor, a blood clot or a bladder disease in the bladder, the bladder is relatively unsuitable to be monitored by adopting an intravesical pressure measurement method, and meanwhile, the measured pressure value can have larger deviation; (3) Research shows that the pressure in the bladder and the pressure in the abdomen only show weak correlation due to the differences of people in gender, age, body mass index and the like; (4) When the measurement is performed by adopting the cystometric method, factors in the operation processes such as the injection rate of physiological saline, the temperature and the like can stimulate the bladder muscle for different individuals, thereby affecting the accuracy of the measurement result.

The abdominal girth measurement method has the advantages that non-invasive measurement can be truly realized in the operation process, and the convenience of measurement is high. However, this method also has some disadvantages: there are many factors affecting the measurement result of the abdominal circumference, whether food intake, age, BMI, etc. have more or less influence on the measurement result, and there may be some difference in the accuracy of the measurement result between different individuals.

In the abdominal wall tension measurement method, there is a difference in the amount of abdominal wall tension measured at different points because there is a difference in the muscles and tendons in the abdomen corresponding to the different points. Currently, more measurement experiments locate a measurement point 5cm below the xiphoid process, and the measurement at this point yields more accurate results than at other points. However, when an incision is present in the patient's abdominal midline due to surgery, this point cannot be selected for measurement. Therefore, a plurality of optional point positions are used for detection, so that the problem that a single measurement point position is inconvenient in the condition of a patient and an inaccurate detection result is caused by temporarily selecting the measurement point position can be effectively avoided. In addition, the difference in the angle of the patient in the supine position, which is a value of the measured abdominal wall tension that is higher than the measured abdominal wall tension of the patient in the supine position by 30 °, also affects the measurement result. Therefore, the abdominal wall tension measurement method needs to be further improved, so that the method can meet the measurement requirements of different individuals.

At present, no effective solution is proposed for the problems that real-time noninvasive monitoring of intra-abdominal pressure and alarming cannot be carried out, different monitoring conditions are required to be set for different people and the like in the related technology.

The abdominal wall tension detection module comprises a miniature motor and a pressure sensor.

The calculation module is composed of an STM32 singlechip and is used for converting the data of the abdominal wall tension detected by the abdominal wall tension detection module into the corresponding numerical value of the intra-abdominal pressure through calculation, calculating the difference value of the abdominal circumference change and comparing the numerical values.

The display module is a display screen and is in communication connection with the calculation module and used for displaying intra-abdominal pressure, abdominal circumference and other data in real time.

If the difference between the values of the abdominal girth change obtained by the subsequent detection and the initially measured abdominal girth change is more than or equal to a preset abdominal girth change difference threshold, the system judges that the abdominal girth is obviously increased, the intra-abdominal pressure is obviously increased, and the alarm module carries out alarm prompt, and if the difference value of the values is less than the preset abdominal girth change difference threshold, the system does not carry out alarm operation. When the displacement detected by the displacement sensor is more than or equal to the movement threshold of the monitoring device, the alarm module alarms to prompt medical staff to timely adjust the position of the monitoring device.
