Problems solved by technology
[0004] 1. Poor measurement accuracy
The accuracy of the measurement results will be directly affected by factors such as whether the pressure measurement line is connected vertically to the urinary catheter, the effectiveness of pressure transmission is difficult to determine, and the patient's end-expiratory phase is difficult to grasp;
[0005] 2. Poor repeatability of measurement results
Using the existing technology to measure intravesical pressure has a great influence of human factors when obtaining the result data, is highly subjective, and lacks objective confirmation conditions, resulting in poor correlation between the continuous measurement results of the same operator or different operators, so the measurement results The repeatability of the data is poor, and the reliability of the clinical application of the data cannot be guaranteed;
[0006] 3. Not convenient for dynamic monitoring
Although the existing technology has a simple device, it is necessary to repeat the corresponding pipeline connection each time during repeated monitoring, and the operation is complicated and time-consuming;
[0007] 4. Poor security
In the existing technology, when measuring the internal bladder pressure, it is necessary to repeatedly connect the urinary catheter and the pressure measuring tube. Due to the many operating links and the open state of the urine drainage loop, it is very easy to cause infection, which increases the risk of critically ill patients with generally low immunity. infection risk

Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings.
[0023] refer to figure 1 . An intra-abdominal pressure monitoring system according to an embodiment of the present invention includes a catheter 1, a pressure sensor 2, a urine collection container 3, a syringe 4, a monitor 5, a first three-way switch 6, a second three-way switch 7, a second An extension tube 8 and a second extension tube 9.
[0024] The urinary catheter 1 includes a connection end 11 and an insertion end 12 for being inserted into a human body. The connecting end 11 of the urinary catheter 1 communicates with the first interface 61 of the first three-way switch 6 through a second extension tube 9, and the urine collection container 3 communicates with the second interface 62 of the first three-way switch 6. The third interface 63 of the three-way switch 6 communicates with the first interface 71 of the second three-way switch 7 through the first ex...

The invention discloses an intraperitoneal pressure monitoring system. The intraperitoneal pressure monitoring system comprises a catheter, a pressure sensor, a urine collection container, a syringe, a monitor, a first three-way switch and a second three-way switch, wherein the connecting end of the catheter is communicated with a first interface of the first three-way switch; the urine collection container is communicated with a second interface of the first three-way switch; a third interface of the first three-way switch is communicated with a first interface of the second three-way switch by a first extension pipe; the syringe is communicated with a second interface of the second three-way switch; the input end of the pressure sensor is communicated with a third interface of the second three-way switch; and the signal output end of the pressure sensor is electrically connected with the signal input end of the monitor. The invention also discloses a method for carrying out pressure monitoring by adopting the intraperitoneal pressure monitoring system. The intraperitoneal pressure monitoring system and monitoring method disclosed by the invention have the advantages that the pressure measuring result is accurate and reliable, the operation is simple and convenient, and the dynamic monitoring is convenient and the like.
Description
technical field [0001] The invention relates to an intra-abdominal pressure monitoring system and a monitoring method thereof. Background technique [0002] The incidence and mortality of acute and critically ill patients are extremely high due to increased intra-abdominal pressure caused by various reasons and abdominal compartment syndrome. One of the main basis for diagnosis is the increase of intra-abdominal pressure. It is extremely important to monitor intra-abdominal pressure, which is helpful for early detection of intra-abdominal hypertension and early diagnosis of abdominal compartment syndrome. In order to reduce trauma, indirect methods are usually used to measure intra-abdominal pressure clinically, such as measuring intravesical, intragastric, rectal or intravenous pressure to reflect intra-abdominal pressure, and transurethral intravesical pressure measurement is considered to be the method of intra-abdominal pressure measurement. The principle of the gold st...
