Urine monitoring device used in non-invasive extracorporeal circulation operation

Abstract

The invention discloses a urine monitoring device used in a non-invasive extracorporeal circulation operation. The urine monitoring device comprises a urine dripping tube and a urinary catheter communicated with the lower end of the urine dripping tube, wherein the urinary catheter is sequentially provided with a dripping speed sensor for measuring the urine dripping speed and a red light sensor for measuring the hemoglobin content in the urine. The dripping speed sensor and the red light sensor are connected to a microprocessor respectively, and the microprocessor is connected to a monitoring device. According to the urine monitoring device used in the non-invasive extracorporeal circulation operation, the urine amount can be automatically discharged every 30 minutes, the urine amount can be observed accurately and statically, and the circulative function, the kidney function, the infusion amount and the pH value of a patient can be known according to the urine volume and the urine color per hour and the vital signs. Furthermore, dynamic urine amount observation can be conducted, due to the fact that the urine monitoring device is provided with a unique Murphy's dripper at a body liquid outlet end, the urine amount per minute can be calculated and speculated through the dripping speed like observing the liquid supplementing dripping speed, the state of illnesses can be diagnosed as soon as possible, and time can be earned for treatment and rescue.

Description

technical field [0001] The invention relates to a urine monitoring device used in non-invasive extracorporeal circulation. Background technique [0002] Urine is an important indicator for monitoring kidney function. During the operation, the volume and quality of urine secreted by the kidney are analyzed, which can monitor the internal environment of the patient's body fluids in real time. In addition, indwelling catheter is a routine operation without trauma. During extracorporeal circulation surgery, a urinary catheter was placed, and the urine volume, color, and specific gravity per unit time were observed and analyzed, and the renal function, cardiac function, and blood volume of the patient were judged, and the therapeutic effects of cardiotonic agents, diuretics, and dehydrating agents were observed. By observing urine volume and urine color, hyperkalemia and hypokalemia can be detected and prevented in time, heart function and effective circulating blood volume can b...

AI Technical Summary

Problems solved by technology

[0005] Due to the large amount of non-colloid priming fluid entering the body of patients undergoing extracorporeal circulation surgery, the urine volume of patients outside the body increases greatly, and the capacity of the daily urine storage bag is not large enough, which increases the number of times the urine drainage device communicates with the outside world; at the same time, itinerant nurses The urine bag needs to be replaced in time, but the replacement and the observation of urine volume and urine color are often affected by the cover of the drooping edge of the sterile towel and the medical staff on both sides of the operating bed; the existing technology cannot accurately monitor the patient's urination, such as urine The amount and presence of urine, urine output, and the amount of urine in the urine storage bottle
