Problems solved by technology

In the urination physiology of catheterized patients, the range of urine flow rate is very wide, from 0-2ml per hour to 1-2L in a few minutes. To meet the real-time and accurate measurement of these two extreme urine flow rates, any single measurement method will Paying a high cost, such an expensive measurement fee cannot be afforded by clinical users, and it is difficult to commercialize and promote
At present, there is no method that can not only meet the requirements of low-cost use but also meet the clinical needs of continuous and automatic measurement of various urinary flow rates

Embodiment 1

[0023] This embodiment provides a device for measuring the urine output of a patient, such as figure 1 -2, including a base 1 and a measuring system, the measuring system is detachably mounted on the base 1;

[0024] The measurement system is composed of a urinary catheter 2, a buffer chamber 3, an upper valve assembly 5, an initial measurement chamber 4, a lower valve assembly 7, a flow sensor 8 and a urine collection bag 9; one end of the urinary catheter 2 is connected to the The inside of the buffer chamber 3, the buffer chamber 3 communicates with the preliminary testing chamber 4 through the upper valve assembly 5; the lower valve assembly 7 communicates with the preliminary testing chamber 4 and the flow sensor 8 respectively, so The flow sensor 8 is also connected to the urine collection bag 9; the base 1 is provided with a screen 11, a keyboard 12, a controller (not shown), a liquid level sensor 13 and a contact module 15, and the upper valve assembly 5. The lower va...

Embodiment 2

[0046] This embodiment provides a method for utilizing the device described in Embodiment 1, and the specific process is:

[0047] When starting to measure, the controller first opens the upper valve assembly, closes the lower valve assembly, and the urine is introduced into the buffer chamber through the urinary catheter, and then flows into the initial measurement chamber through the upper valve assembly. When the urine volume reaches the quantitative value (such as 1mL) corresponding to the liquid level sensor, it will trigger the liquid level sensor at the corresponding position, and the liquid level sensor will send the liquid level signal to the controller, and the controller will start the first cycle of measurement The cycle is 30 minutes (not limited to 30 minutes), and the measurement interval is determined according to the time when the liquid level reaches the quantitative value. For example, the patient's urine output can reach the liquid level within 2, 5, 10, 15,...

Abstract

The invention discloses a device and a method for metering the urination volume in continuous minutes. Step-by-step measurement is adopted, firstly the urination volume state of a patient is judged by using a primary measurement chamber, the opening and closing interval time of a valve is decided according to the urination volume state of the patient, and then the urine flow of the patient in the interval time is accurately measured by using a flow sensor, the minute urine flow and the hour urine flow are calculated according to the measured urine flow, and the variation rate of the minute urine flow rate is calculated in the normal range of the urine flow. Various required urination amount information is provided for clinic, the cost is controlled in a clinically acceptable range, and the method is suitable for popularization and commercial conversion.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a device and method for measuring continuous minute urine output. Background technique [0002] Urine output (UO) is an important clinical parameter to measure renal function and blood volume status, and is an important sign of critically ill patients. Almost all critically ill patients need to indwell FOLEY catheter to drain the urine in the patient's bladder for monitoring patients UO for better fluid management to reduce acute kidney injury (AKI) and acute lung injury (ALI). A kind of closed precision urine bag is widely used in the hospital to measure the urine output. This non-automated precision urine bag relies on printed volume markings on rigid small-volume collection trays or larger-volume collapsible collection bags to subjectively interpret urine levels, which is error-prone and requires heavy manual labor to use, Healthcare workers are at potential risk of repeate...
