Embodiment Construction

[0143] Detailed description of the preferred embodiment

[0144] The following description is provided together with all sections of the invention to enable one skilled in the art to utilize the invention and to set forth the best mode contemplated by the inventors for carrying out the invention. However, various modifications will still be apparent to those skilled in the art, since the general principles of the invention have been specifically defined to provide a method for monitoring intra-abdominal pressure (IAP) and urine output (OU), typically in human patients. Tools and methods, which rely on the controlled transfer of urine from the bladder to the collection bag, rather than on the free flow of urine from the bladder.

[0145] Disadvantages of prior art devices, systems and methods

[0146] Prior art methods have disadvantages such as:

[0147] a. If the urine-fill tube does not slope downward along its entire length, free-flowing urine may form a disconnected se...

Abstract

A device for measuring a rate of production of urine in a patient comprising a catheter; a pressure transducer; and a means for measuring the amount of urine produced. Urine flow from the bladder is prevented until a predetermined pressure is reached in the bladder. Urine flow is then allowed; the bladder pressure and the volume of urine exiting the bladder are measured. When the bladder pressurereaches a second, lower predetermined pressure, urine flow is again prevented. From the measured pressure during urine flow and from the volume of urine exiting the bladder, the intra- abdominal pressure and the urine production rate can be determined.

Description

technical field [0001] The present invention relates generally to medical monitoring and measurement equipment, and more particularly to physiological parameter measurement equipment. The invention relates in particular to a device configured as an assembly for measuring urine output and intra-abdominal pressure in hospitalized patients. Background technique [0002] The diagnostic value of a patient's urine output (UO) as a tool to assess a patient's progress in recovery from a medical condition is well established in the medical literature. For example, a gradual decrease in a patient's UO over time often predicts an increased risk of renal failure. By monitoring a patient's UO, physicians or medical support personnel can be forewarned of complications that may affect the patient's health and safety. In this case, appropriate countermeasures can be taken before other physiological parameters of the patient show signs of problems, and before a life-threatening situation o...
