Abstract
Abstract The present invention relates to a device for the sampling of blood or other body fluids which includes means for the direct measurement of the analyte of interest within the fluid. Also disclosed is a `closed-loop` device and method wherein the analyte is measured and the required amount of drug is determined and injected, without removal of the device from the patient's body.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
109 words
A fluid sampling device for sampling fluid from a patient, comprising: (a) a sampling needle, which needle takes up blood or other body fluid from a patient by means of capillary action or other hydrodynamic forces or by means of both capillary action and other hydrodynamic forces; (b) a sensor, the entirety of which is included in the sampling needle, which sensor detects an analyte of interest in the fluid; and (c) an analysis means which receives and processes a signal from the sensor, said analysis means of said fluid sampling device processes said signal after said sampling needle of said fluid sampling device is removed from said patient.
Claim 2
Dependent Claim
109 words
A fluid sampling device for sampling fluid from a patient, comprising: (a) a sampling needle, which needle takes up blood or other body fluid from a patient by means of capillary action or other hydrodynamic forces or by means of both capillary action and other hydrodynamic forces; (b) a sensor, the entirety of which is included in the sampling needle, which sensor detects an analyte of interest in the fluid; and (c) an analysis means which receives and processes a signal from the sensor, said analysis means of said fluid sampling device processes said signal after said sampling needle of said fluid sampling device is removed from said patient.
Claim 3
Dependent Claim
15 words
The device of claim 1 wherein the sensor is an optical sensor or electrochemical sensor.
Claim 4
Dependent Claim
14 words
The device of claim 1 wherein the analysis means further comprises a display function.
Claim 5
Dependent Claim
12 words
The device of claim 1 wherein the analyte of interest is glucose.
Claim 6
Dependent Claim
16 words
The device of claim 2 wherein the optical sensor includes an enzyme immobilized in a membrane.
Claim 7
Dependent Claim
17 words
The device of claim 5 wherein the immobilized enzyme is located on a conduit for transmitting light.
Claim 8
Dependent Claim
11 words
The device of claim 6 wherein the enzyme is glucose oxidase.
Claim 9
Dependent Claim
16 words
The device of claim 2 wherein the electrochemical sensor includes an enzyme immobilized in a resin.
Claim 10
Independent Claim
194 words
A method of sampling fluid from a patient to determine the presence or amount of an analyte of interest in said fluid, said method comprising the steps of: (a) providing a sampling device which comprises a sampling needle, which needle is capable of taking up blood or other body fluid from a patient by means of capillary action or other hydrodynamic forces or by means of both capillary action and other hydrodynamic forces, a sensor, the entirety of which is included in the sampling needle, which sensor detects the presence or amount of said analyte of interest in the fluid, and an analysis means which receives and processes a signal from the sensor; (b) introducing the sampling needle into the patient; and (c) allowing the sampling needle to take up blood or other body fluid, whereby the blood or other body fluid comes into contact with the sensor, whereby a signal correlated to the presence or amount of said analyte of interest in the fluid is received and processed by the analysis means, provided that said sampling needle is removed from said patient prior to the processing of the signal by the analysis means.
Claim 11
Independent Claim
194 words
