CN102151135A - Automatic urine volume counter - Google Patents

Abstract

The invention discloses an automatic urine volume counter. The automatic urine volume counter comprises a urine storage bag; a urine dropper is arranged above the urine storage bag; and a photoelectric sensor which is used for acquiring a urine dropping speed signal and transmitting the urine dropping speed signal to a urine volume monitoring device is arranged on the near side of the urine dropper. The automatic urine volume counter has a rational structure; a urine dropper sensor is connected with a urine volume monitor on the bedside, so the urine volume monitor can automatically display and accumulate the urine volume in real time; moreover, the automatic urine volume counter saves time and labor, greatly reduces the working load of nursing, and needs no personnel intervention for long time; due to the use of the automatic counting urine bag without manual operation, the risk of hospital infection is reduced greatly; the urine volume of a critical patient can be counted precisely every 24 hours or every hour; and the automatic urine volume counter is favorable to intake and output management of transfusion therapy, and is safe and convenient.

Description

Automatic uri-meter measuring device

Technical field

The present invention relates to a kind of uri-meter measuring device.

Background technology

In clinical nursing activity, the urine amount can in time reflect renal perfusion, blood volume and total body perfusion situation and body fluid balance, and can reflect renal function, cardiac function and circulation volume state, especially the critical patient behind burn, the operation on heart is one of important indicator of tight monitoring.Therefore, tight monitoring and accurate metering to the urine amount for instructing clinical liquid undergoing treatment, prevent and treat severe complications and play a very important role; In critical illness patient's management, strengthen the close observation of urine amount, accomplished 24 hours and per hour the monitoring of urine amount be to instruct one of means of further treating; Can help simultaneously EARLY RECOGNITION acute renal failure patient down in the hole, carry out clinical intervention early.At present, when clinical practice is operated the monitoring of urine amount, the nurse regularly is poured on urine in the graduated measuring cup, check the amount and the record of urine by naked eyes, traditional measurement method is limitation, the scale of common urinal and actual urine discharge capacity are not inconsistent, and cause medical worker's measurement error, influence the accuracy of urine metering; The frequent work load that has increased hospital care again greatly of measuring.

Summary of the invention

The object of the present invention is to provide a kind of rational in infrastructurely, can show automatically in real time and the automatic uri-meter measuring device of accumulative total urine amount.

Technical solution of the present invention is:

A kind of automatic uri-meter measuring device is characterized in that: comprise the urine storage bag, the top of urine storage bag is provided with the urine dropper, and the nearside of urine dropper is provided with the collection urine and drips fast signal and urine is dripped the photoelectric sensor that fast signal is transferred to urine amount monitor device.

Described photoelectric sensor comprises infrared transmitting tube and the photoelectricity adopter that is distributed in urine dropper both sides respectively; Infrared transmitting tube is made up of the PN junction of GaAS, and luminescence peak is 9400; Described urine amount monitor device adopts embedded microcomputer chip, and system clock is 12MHz.

The present invention is rational in infrastructure, is connected with the other urine amount of bed monitor by urine dropper pick off, and urine amount monitor shows in real time and accumulative total urine amount automatically; This instrument probe portion adopts the infraluminescence pipe, is made up of the PN junction of GaAS.Luminous honeybee value is 9400, is in outside the visible light wave range, can significantly reduce the interference of visible light.The response speed of GaAS diode is tens nanoseconds of orders of magnitude, uses the response speed that can obtain the rise time and be about 2 μ s fall time with phototransistor combination.Up-to-date embedded microcomputer chip is adopted in the core, and system clock is up to 12MHz.Owing to used high performance microcomputer chip, so system does very small and exquisitely, reliable, and not only the very faint conversion of signals that pick off can be come becomes reliable control signal, can will calculate current speed, the flow of dripping simultaneously.

The present invention can be under the sight that need not open the closed system of urinating, in time, accurately the urine amount is shown, so that medical personnel grasp monitoring index fast and accurately, be beneficial to clinical intervention early, measurement result accurately and reliably, average percentage deviation reduces the human error in 10%; Can be time saving and energy saving, reduce the load of nursery work greatly, the personnel that can need not for a long time intervene; Need not manually-operated automatic gauge urinal and use, greatly reduce the risk of hospital infection; The critical patient is per hour reached urine amount statistics in 24 hours accurately, help the discrepancy buret reason of infusion treatment, safe ready.
