The invention relates to the technical field of data analysis, and particularly discloses a data analysis method and system for acute kidney injury, and the method comprises the steps: integrating the multi-source acute kidney injury data of a patient, including clinical information and historical medical records, constructing the time series data of serum creatinine, urine volume and the like, extracting the risk features in an unstructured text by using an NLP technology, and analyzing the risk features in the unstructured text. Physiological index dynamic and semantic risk factors are deeply fused through space-time alignment, a basic feature vector is formed, a difference risk score of historical and current states is calculated in combination with sliding window features of historical medical records, when the score exceeds a preset threshold value, it is judged that a dynamic evolution risk exists, an advanced intervention instruction is automatically generated, and early intervention is achieved. Therefore, the problems of single data dimension, risk identification lagging and untimely intervention of a traditional method are solved.

Provided is a system that more accurately estimates the degree of urine accumulation by solving a problem in which the influence of a change in the amount of urine accumulation is obscured when the biological impedance in the vicinity of the bladder is affected as the muscles contract. This urine accumulation degree estimation system (2) comprises: a measurement means for measuring at least two types of biological impedance by energizing a bladder (60) at at least two different frequencies; and an estimation means that estimates the urine accumulation degree of the bladder (60) on the basis of the at least two types of biological impedance. The at least two frequencies include a frequency at which the bladder (60) and the muscles (66) around the bladder can be energized, and a frequency at which the muscles (66) around the bladder can be energized.

This invention relates to the field of multi-organ dysfunction (MOD) early warning technology, specifically to an MOD early warning method for patients with severe burns. The method includes the following steps: acquiring heart rate, mean arterial pressure, respiratory rate, blood oxygen saturation, lactate concentration, and urine output per unit time; calculating the rate of lactate change at adjacent time points to form a sequence; comparing the rate of change across time intervals to obtain the difference in change; combining heart rate and blood oxygen saturation to calculate circulatory load; and counting the number of early warning triggers that meet risk conditions. In this invention, by calculating the rate of change of lactate concentration at adjacent time points and combining it with interval direction statistics, tissue metabolic changes show trend characteristics; the rate of change of urine output combined with mean arterial pressure forms a record of renal perfusion changes, providing a continuous characterization of perfusion status; heart rate and blood oxygen saturation are used to calculate circulatory load; multiple physiological signals are linked for judgment; and recurring abnormalities are expressed through the number of triggers. This improves the stability and predictability of MOD risk identification in critically burned patients.

This present disclosure relates to fluid therapy based on adjusted urine output rate and / or sodium output rate, and associated systems, devices, and methods. Exemplary methods can include receiving a sodium excretion input for the patient; receiving a urine output rate; determining an adjusted urine output rate based on the sodium excretion input and the urine output rate; and providing fluid therapy based on the adjusted urine output rate. By determining the amount and / or rate of the infused diuretic and / or hydration fluid based on a patient's actual sodium excretion levels, embodiments of the present technology can optimize and / or customize all or a subset of a diuretic therapy to an individual patient's physiology.

[Problem] An object of the present invention is to provide a method of estimating / evaluating a urinary excreted substance amount per unit time based on a finding that a urinary substance concentration can be quite accurately and practically estimated by considering an estimated glomerular filtration rate and a net urinary substance excretion rate. [Solution] The method of evaluating a urinary substance excretion amount per unit time includes: multiplying a concentration of an arbitrary urinary excreted substance present in the serum by: an estimated glomerular filtration rate per unit time, a numerical value (net urinary substance excretion rate) obtained by dividing a clearance of the arbitrary urinary excreted substance present in the serum by a glomerular filtration rate, and a predetermined coefficient.

Embodiments disclosed herein are directed to a self-learning bladder volume monitoring system. The system can include a bladder volume (BV) system configured to measure an electrical impedance of a bladder region of a patient and determine a volume of fluid disposed therein using an impedance to bladder volume model (“By model”). Further, the system can measure a total body water (“TBW”) for the patient and modify the BV model to account for variations in TBW within the tissues surrounding the bladder providing a more accurate bladder volume measurement. The system can include a “training unit” which can include one of a user input interface, an automatic urine output monitoring system, an ultrasound system, and an intrabladder pressure system configured to verify a volume of fluid within or voided from the bladder and train the BV model.

A urination analysis device that analyzes urination performs: acquiring image data captured by a camera which is located at a toilet to photograph a bowl of the toilet; calculating a urination pixel number being the number of pixels of an image showing urination from the image data when the urination by a user is detected by image recognition of the image data; calculating, on the basis of a change in the urination pixel number, a flow momentum value of the urination, a urine quantity, and a urine specific gravity; and outputting the flow momentum value, the urine quantity, and the urine specific gravity.

Most of the various products sold commercially to prevent male urinary incontinence have the drawback of causing urine to stain or leak and adhere to the testicles. [Solution] The present invention is an undergarment called "pleasure-relieving pants," which consists of a pant-shaped piece of fabric smaller than regular pants, with the lower part forming a pouch to collect urine. A slit is provided in the upper part, called the lower abdominal band, to allow the penis to be removed. The use of stretchy fabric such as spandex minimizes gaps, preventing the penis from easily retracting. Regarding itching relief, for small amounts of urine, such as slight stains, the urine collection bag can be made of ordinary cloth and can be used without anything inside. However, for larger amounts of urine, waterproof or water-repellent fabric should be used, and gauze, cotton wool, paper towels, absorbent cloth, or superabsorbent polymer should be placed inside the urine collection bag. If the expected amount of urine exceeds the size of the bag, the bag can be made larger and more absorbent material can be added to collect more urine, making urination easier.

This invention provides a urine bag carrying device that allows highly active users to safely and comfortably carry a urine bag even when they have a large urine output. [Solution] The present invention is a urostomy bag carrying device characterized by having an upper left wing and an upper right wing, and a lower left wing and a lower right wing provided on a base material made of fabric large enough to support the entire surface of the urostomy bag body, as well as an elastic first band connecting the upper left wing and the lower right wing, and an elastic second band connecting the upper right wing and the lower left wing, thereby allowing the urostomy bag to expand.
