Embodiment 1

[0025] Embodiment 1, the method for reflecting the intra-abdominal pressure by intravesical pressure measurement comprises the following steps: 1) emptying the liquid in the bladder; 2) measuring the amount of urine produced in the bladder per unit time to obtain the speed of urine production; 3) Calculate the time required for the amount of urine in the bladder to accumulate to 50 ml, and start timing; 4) After the timing is completed, measure the bladder pressure and convert it into intra-abdominal pressure; 5) Repeat the above steps to complete the periodic measurement;

[0026] Comparing the bladder pressure or intra-abdominal pressure obtained in step 4) with the normal value, judging whether it has increased or decreased, and sending an alarm signal when it is judged to be yes;

[0027] Such as figure 1 As shown, the device for reflecting intra-abdominal pressure through intravesical pressure measurement includes urinary catheter 1, urine volume measuring device, bladder...

Embodiment 2

[0029] Embodiment 2, when the patient can no longer produce urine, or the amount of urine produced is too small to meet the measurement needs, an active infusion device is used, such as figure 2 As shown, the rest are the same as in Embodiment 1, and also include an active infusion device, which communicates with the urinary catheter 1; the active infusion device includes a fluid storage bag 10, a dropper 11, a first peristaltic pump 12, and a fluid storage tube connected in sequence. 13. The second peristaltic pump 14, the second peristaltic pump 14 communicates with the urinary catheter 1, the liquid storage bag 10 and the liquid storage tube 13 are equipped with liquid level sensors, the first peristaltic pump 12, the second peristaltic pump 14, the liquid level The sensors are all electrically connected to the main control board 2, and the capacity of the liquid storage tube 13 is 50 milliliters.

[0030]The specific use process is that after the liquid in the bladder is ...

Embodiment 3

[0031] Embodiment 3, when the patient can no longer produce urine, or the amount of urine produced is too small to meet the measurement needs, an active infusion device is used, such as image 3 As shown, the rest are the same as in Embodiment 1, and also include an active infusion device, which communicates with the urinary catheter 1; the active infusion device includes a liquid storage bag 10, a dropper 11, a first check valve 15, and a syringe that are pushed in sequence. And the detection device 16, the second check valve 17, the electromagnetic shut-off valve 18, the liquid storage bag 10 is provided with a liquid level sensor, the syringe push and detection device 16, the electromagnetic shut-off valve 18, and the liquid level sensor are all electrically connected to the main control board 2 , The syringe pushing and detecting device 16 includes an injection syringe 19, and the volume of the injection syringe 19 is 50 milliliters.

Abstract

The invention discloses a method and a device for reflecting an intra-abdominal pressure by measuring a pressure in the bladder. The method comprises the following steps: 1) emptying liquid in the bladder; 2) measuring the amount of urine generated in the bladder in unit time and obtaining the speed of generating the urine; 3) calculating the time required for accumulating the amount of the urine generated in the bladder to be 50ml and starting timing; 4) after the timing is finished, performing measurement to obtain the bladder pressure and converting the bladder pressure into the intra-abdominal pressure; and 5) repeating the steps to finish periodic measurement. The device comprises a catheter, a urine amount measurement device, a bladder pressure measurement device, a main control board, a display screen and a controller, wherein the catheter is communicated with the urine amount measurement device and the bladder pressure measurement device; the urine amount measurement device comprises a urine discharge electromagnetic valve, a drainage bag and a weighing sensor; and the bladder pressure measurement device comprises a Luer cock valve and a pressure sensor. The device is simple in structure and convenient to operate, relieves the pain of patients and lowers the infection risk of the patients.

Description

technical field [0001] The invention relates to the technical field of medical detection equipment, in particular to a method and a device for reflecting intra-abdominal pressure through intravesical pressure measurement. Background technique [0002] In recent years, the increase of intra-abdominal pressure (IAP) and its impact on cardiopulmonary function and the function of important intra-abdominal organs (such as kidney and gastrointestinal tract) have become a research topic of intensive care medicine and surgeons. , Intra-abdominal pressure monitoring has gradually become one of the monitoring items for critically ill patients. Through the monitoring of bladder pressure, timely understanding of changes in intra-abdominal pressure of patients can reflect conditions such as multiple organ dysfunction syndrome (MODS, Multiple organ dysfunction syndrome) and so on. Severity and prognosis judgment, reduce the occurrence of complications, and improve the success rate of resc...
