Description
Technical Field
The invention relates to the field of monitoring of bladder pressure, in particular to a device and a system for monitoring bladder pressure information.
Background
Intraradicular hypertension (IAH) and interperitoneal space syndrome (ACS) are significant factors that contribute to increased mortality in critically ill patients. The condition of a series of pathophysiological changes and clinical manifestations even life threatening due to increased intra-abdominal pressure is called Abdominal Compartment Syndrome (ACS), measuring intra-abdominal pressure >20mmHg. IAP elevation impairs gut function, which is a major cause of multiple organ dysfunction, and rapid IAP elevation to form ACS can directly lead to multiple organ dysfunction and even failure. The death rate of patients is 10-30% within 3h after ACS occurs, the death rate of patients after 24h treatment is more than 66%, and if the patients can be decompressed in time, the survival rate can reach 59%. Mortality rates in IAP >35mmHg in conservative treatments reach 100%, even in operators up to 90%.
At present, the clinical gold standard for indirectly measuring the abdominal pressure is a bladder pressure measurement method, a catheter is placed, a certain amount of physiological saline is injected after the bladder is emptied, and the height of liquid in an infusion tube is observed to be the pressure in the bladder. Generally, during surgery and after surgery, patients are unconscious or otherwise unable to urinate autonomously, such as patients with neurological diseases such as spinal cord injury, and the like, lose the ability to sense the state of bladder fullness, resulting in urinary retention, and as a result, the pressure caused by urine can severely damage the bladder and kidneys of the patient, and only urinate by inserting a catheter into the patient.
Hospitalized patients, particularly those in the ICU, often use urinary catheters for urination to relieve bladder pressure. The operation of indirectly monitoring the abdominal pressure by a bladder pressure measurement method is complex, the precision requirement is high, bladder filling is required to be performed firstly, and large individual differences exist due to complex conditions; for general inpatients, a catheter is inserted into a urethral orifice for catheterization, most of the general inpatients are directly discharged into a drainage urine bag and discharged by a nursing person after the general inpatients are fully collected, if the open catheter is used for a long time, the functions of contraction and expansion of the bladder can be slowly degraded, and particularly, the old and women need to recover for a period of time after being discharged, and side effects such as urinary incontinence and the like can be possibly generated; to the patient who uses the catheter urination at ICU, generally adopt and insert the catheter and urinate after the catheter at bladder upper shed, because the urine is more muddy in patient's postoperative bladder, and the bore of catheter opening is less, often can be blockked up, when the amasss liquid in the bladder was too much, the urine can directly flow from the urethra, increases nursing work. A large-scale survey data shows that 93.3% -95.4% of serious patients retain catheters in the ICU in China. Because the ICU internal nursing work is heavy, the number of nursing staff is limited particularly during night work, the catheter is usually opened for a patient with the catheter remaining, and although the urine drainage can be kept smooth, the bladder contraction function is easy to deteriorate, and the recovery is not facilitated.
