example 1

[0277] Example 1: The first-level (for example, particle-insensitive) optical sensor can be configured to measure fluids in the wavelength range of about 850nm to about 870nm, and the second-level (for example, particle-discriminating) optical sensor can be configured to measure from about 400nm to about Measure fluids between the 420nm waveband. The sensor output voltage measured by the first-stage optical sensor is 0.95V. The output voltage measured by the second-level optical sensor is about 0.15V.

[0278] Figure 38A with Figure 38B It depicts the application of correlation graphs to identify particle type and concentration based on these two signals output from the first and second level optical sensors. Figure 38A It is the superposition of the sensor signal (for example, optical measurement at one wavelength in the first wavelength range or wavelength band (for example, infrared)) and white blood cell concentration and the predetermined correlation of sensor signal and ...

example 2

[0280] Example 2: In this example, the two levels of light scattering / absorption can be performed at wavelengths with different absorption characteristics for different particle types. The first-level (for example, particle-insensitive) optical sensor can be configured to measure fluid at a wavelength of about 260 nm (wavelength C), and the second-level (for example, particle-discriminating) optical sensor can be configured at another cell-specific wavelength ( The fluid is measured at wavelength D). The output voltage of the sensor measured by the first-stage optical sensor is about 0.950V. The output voltage measured by the second-level optical sensor is about 0.194V.

[0281] Similar to example 1, you can use Figure 39A with 39B The correlation graph for different particle types is shown to analyze the first and second level sensor data. specifically, Figure 39A It includes the superposition of the sensor signal output measured at the wavelength C to the WBC and the sensor...

Abstract

A patient monitoring system may be used with catheters to monitor the infusion and drainage of any solution into the human body. The system may be used, for example, with in-dwelling catheters for peritoneal dialysis in end stage renal disease (ESRD) patients, urinary tract catheters, insulin pumps in diabetic patients, feeding tubes and central venous line catheters. The patient monitoring systemincludes one or more fluid pathways for infusing into and/or draining solutions out of the catheter, and one or more sensors to monitor the fluid. The patient monitoring system transmits the patientmonitoring data to a database, allowing data storage, processing, and access through graphical user interfaces to patients and providers via device applications or browser-based web access portals.

Description

[0001] Cross references to related applications [0002] This application claims priority to the U.S. Provisional Application Serial No. 62 / 599,619 filed on December 15, 2017 and the U.S. Provisional Application Serial No. 62 / 731,339 filed on September 14, 2018, the entire contents of which are incorporated herein by reference. in. Background technique [0003] Many chronic diseases rely on patients for self-administration of outpatient treatment or administration by home caregivers, including injecting fluid into and / or expelling fluid from the body through a catheter or tube. Examples of these treatments include, but are not limited to, permanent indwelling catheters for peritoneal dialysis in patients with end-stage renal disease, urinary catheters, catheters used with insulin pumps in diabetic patients, permanent or temporary feeding tubes, ascites drainage Application of catheters, drainage catheters for hydrocephalus and various central venous catheters. For treatments with...
