Intelligent urine volume measuring system based on ultrasound

Abstract

The invention discloses an intelligent urine volume measuring system based on ultrasound, and belongs to the technical field of medical apparatuses and instruments. When the intelligent urine volume measuring system based on the ultrasound is adopted, the urine volume of a patient can be accurately recorded, manual participation is not needed in the measuring process, safety and reliability are achieved, and medical care quality and medical care efficiency can be effectively improved. The intelligent urine volume measuring system based on the ultrasound comprises ultrasound receiving and transmitting units, a control unit and a container for containing urine, wherein the container for containing the urine is of a central symmetry structure, four or more ultrasound receiving and transmitting units are symmetrically arranged on the top of the container along the center of the container, and each ultrasound receiving and transmitting unit is connected with the control unit; when the volume of the urine in the container needs to be measured, the ultrasound receiving and transmitting units arranged on the top of the container are started to send transmitting waves out, the transmitting waves return to form reflected waves after reaching the liquid surface, and the reflected waves are received by the ultrasound receiving and transmitting units; the control unit obtains the time interval between the time when the ultrasound receiving and transmitting units send the transmitting waves out and the time when the ultrasound receiving and transmitting units receive the reflected waves through measurement, and the volume of the urine in the container can be further obtained.

Description

technical field [0001] The invention relates to a urine volume measurement system, in particular to an ultrasonic-based intelligent urine volume measurement system, which belongs to the technical field of medical devices. Background technique [0002] Urine volume monitoring is the most direct and sensitive physiological indicator reflecting the level of renal blood perfusion, especially for patients with shock, heart surgery, extensive burns, and renal insufficiency. Urine volume can reflect the effective circulating blood volume and kidney function in a timely manner. It can predict the disorder of renal function before the increase of serum creatinine, and provide reliable basis for clinical diagnosis and treatment for medical personnel. [0003] Clinically, the accuracy and timeliness of urine volume monitoring are far from enough. Most hospitals still use the following three methods for manual intermittent static monitoring: [0004] (1) Use a disposable urine storage ...

AI Technical Summary

Problems solved by technology

[0005] (2) Use precision urine bags - although the accuracy has been improved, it is necessary to observe and record the urine volume every hour, which brings a lot of inconvenience to the medical staff

[0006] (3) Nurse’s manual container measurement—accuracy is required to meet the standard, but it is extremely cumbersome and inconvenient

There are hidden dangers in the environment and cross-infection, and it takes up a lot of nursing resources and time

[0007] In addition, clinical intensive care work is heavy, and the urine output information of most critically ill patients is often caused by human errors due to various reasons such as shift shifts; missed detection, missed records, and recording errors occur from time to time, which may cause delays or serious problems in clinical judgment. fault
