Urine volume monitor

Abstract

The invention discloses a urine volume monitor. A bracket comprises a hook for hanging a drainage bag; the hook is provided with a weighing sensor which is used for transmitting information after the urine is weighed in the drainage bag to the monitor; the bracket comprises a urine detection box which can be opened or closed and can buckle a conduit in the box; a photodiode and a photoelectric detector are arranged in the urine detection box; and light emitted from the photodiode transmits through the conduit and urine flowing in the conduit in real time, then is collected by the photoelectric detector and is transmitted to the monitor. According to the urine volume monitor, the urine volume is calculated by using a urine refraction proportion analytical method, and a measuring device is not contacted with the urine when the urine is measured, so that the urine measuring accuracy is improved, the antijamming capability is strong; and besides, urine volume data of patients can be displayed or output in real time, and urine volume history information can be reviewed, the requirement of clinicians on the urine volume information dynamic monitoring is met, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a urine volume monitor, in particular to a dynamic urine volume monitor. Background technique [0002] Urine flow is an important indicator reflecting the dynamic balance of body fluids and heart and kidney function. Accurate urine volume monitoring is helpful for judging changes in the condition and guiding the formulation of treatment plans. Now the urine volume monitoring of critically ill patients has been developed to observe the urine volume every hour or even every minute, and the urine volume monitoring methods clinically used in hospitals include measuring cup (tube) monitoring method, syringe monitoring method and precision urine bag monitoring There are deficiencies in the accuracy, comprehensiveness and nosocomial infection prevention of monitoring. More importantly, this method of adopting traditional urine bags and measuring cups has been unable to meet the needs of digitalization and informationization required ...

AI Technical Summary

Problems solved by technology

However, this filter element is extremely easy to block during clinical use, and once blockage occurs, the urine bag can only be replaced (this increases the patient's use cost and nursing workload);

[0014] 2) Because the photoelectric meter drop method is used, and the urine drop passes through the photoelectric detection head under the action of gravity, continuous drops often occur, and the measurement accuracy is difficult to achieve high;

[0015] 3) This photoelectric drop method has poor anti-interference ability

When there is a large external disturbance (for example: changing the urine bag, turning over the patient and nursing care, etc.), a large measurement error will occur. In order to avoid malfunction and measurement error in the case of strong external interference, only the method of suspending the measurement can be used. process;

[0016] 4) Only return visits can be made to the urine volume data at a set single interval;

[0017] 5) There is no recorded waveform of urine flow

Network information transmission is not possible;

[0018] 6) The operation process is relatively complicated, and a large number of parameter settings are required for each use;

[0019] 7) It is necessary to use specially customized urine collection bags, which are expensive as consumables and limit the scope of use in hospitals

[0031] 1) The anti-interference ability is poor, and the ability to respond to some strong external interference in the ICU and other occasions is weak in clinical use. In order to avoid misoperation and measurement errors in the case of strong external force interference, external measures to suspend measurement can only be used for processing ;

[0032] 2) It is impossible to realize the return visit of historical urine volume information in the true sense (only 168 pieces of urine volume information can be stored), and the return visit of historical urine volume information is one of the urine volume information that clinicians are most concerned about, so it affects the clinicians. enthusiasm;

[0033] 3) The specific gravity of urine is set by human observation and judgment, which is arbitrarily large and has low accuracy, resulting in large errors when converting urine volume into volume;

[0034] 4) There is no data networking function, and the data network in the ICU ward of the hospital cannot be shared;

[0035] 5) The display screen adopts a monochrome dot matrix screen, with a single display interface, less information, and low brightness;

[0036] 6) The system parameters that need to be set are large, and the operation is cumbersome;
