Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
133 words
A device for delivering a drug directly to the body of a patient, comprising: (a) a needle for taking us 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 included in the needle, which sensor detects an analyte of interest or concentration thereof in the blood or other body fluid; (c) an analysis means for receiving and processing a signal from the sensor and sending a signal representative of the analyte of interest or the concentration thereof to (d) a control device for transmitting a signal to an injection actuator; and (e) an injector for delivering the required amount of the drug in response to the injection actuator via the needle.
Claim 2
Independent Claim
133 words
A device for delivering a drug directly to the body of a patient, comprising: (a) a needle for taking us 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 included in the needle, which sensor detects an analyte of interest or concentration thereof in the blood or other body fluid; (c) an analysis means for receiving and processing a signal from the sensor and sending a signal representative of the analyte of interest or the concentration thereof to (d) a control device for transmitting a signal to an injection actuator; and (e) an injector for delivering the required amount of the drug in response to the injection actuator via the needle.
Claim 3
Dependent Claim
24 words
The device of claim 1 wherein the control device includes a user input for determining the required amount of the drug to be injected.
Claim 4
Dependent Claim
24 words
The device of claim 1 wherein the control device includes an analytical method for determining the required amount of the drug to be injected.
Claim 5
Dependent Claim
12 words
The device of claim 3 wherein the analytical method is an algorithm.
Claim 6
Independent Claim
176 words
A method of delivering a drug directly to the body of a patient, comprising: (a) providing (1) a 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; (2) a sensor included in the needle, which sensor detects an analyte of interest or concentration thereof in the blood or other body fluid; (3) an analysis means for receiving and processing a signal from the sensor and sending a signal representative of the analyte of interest or the concentration thereof to a control device for transmitting a signal to an injection actuator; (b) providing a drug delivery device which comprises the control device for transmitting a signal to the injection actuator, and an injector for delivering the required amount of the drug in response to the injection actuator via the needle; (c) introducing the needle into the patient; and (d) delivering the required drug dosage in response to the injection actuator.
Claim 7
Independent Claim
176 words
A method of delivering a drug directly to the body of a patient, comprising: (a) providing (1) a 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; (2) a sensor included in the needle, which sensor detects an analyte of interest or concentration thereof in the blood or other body fluid; (3) an analysis means for receiving and processing a signal from the sensor and sending a signal representative of the analyte of interest or the concentration thereof to a control device for transmitting a signal to an injection actuator; (b) providing a drug delivery device which comprises the control device for transmitting a signal to the injection actuator, and an injector for delivering the required amount of the drug in response to the injection actuator via the needle; (c) introducing the needle into the patient; and (d) delivering the required drug dosage in response to the injection actuator.
