Disclosed is a sample element for holding a volume of bodily fluid drawn from the skin of a patient at a withdrawal site. The sample element comprises a housing defining a sample chamber therein, and a barrier. The barrier has a first side configured to contact the skin of the patient at the withdrawal site, and a second side in fluid communication with the sample chamber. The barrier is configured to be pierced by a lance, to permit the bodily fluid to pass from the first side to the second side. Also disclosed is a method of drawing a bodily fluid from the skin of a patient at a withdrawal site. The method comprises placing a first side of a barrier against the skin of the patient at the withdrawal site. The method further comprises forming a first opening through the barrier and a second opening in the skin of the patient at the withdrawal site. The first opening and the second opening are in fluid communication. The method further comprises placing a sample chamber in fluid communication with a second side of the barrier.

Disclosed is a sample element for holding a volume of bodily fluid drawn from the skin of a patient at a withdrawal site. The sample element comprises a housing defining a sample chamber therein, and a barrier. The sample element also comprises a vacuum source. The barrier has a first side configured to contact the skin of the patient at the withdrawal site, and a second side in fluid communication with the sample chamber. The barrier is configured to be pierced by a lance to permit the bodily fluid to pass from the first side to the second side. Additionally, the vacuum source can be actuated to draw the bodily fluid through the barrier and into the sample chamber. Also disclosed is a method of drawing a bodily fluid form the skin of a patient at a withdrawal site. The method comprises placing a first side of a barrier against the skin of the patient at the withdrawal site. The method further comprises forming a first opening through the barrier and a second opening in the skin of the patient at the withdrawal site. The first and second openings are in fluid communication. The method further comprises applying suction at the first opening of the barrier to draw a bodily fluid from the patient.
摘要:
A system for management of a chronic medical condition generally comprises a plurality of networked physical and/or virtual elements configured to cooperate to aid in management of a chronic medical condition of a patient. The system is configured to provide a primary caregiver with current data relating to the patient's medical condition, and to allow the caregiver to provide appropriate changes to the patient's treatment via an analyte detection meter. The meter is generally configured to calculate a treatment dosage by combining a plurality of patient-affected and caregiver-affected variables. One embodiment relates to a system for management of a diabetic condition in which the primary caregiver is provided with glucose concentration data as well as other information relating to a diabetic condition. The primary caregiver can then make appropriate changes to correction factors to be implemented in an analyte detection meter which is configured to calculate an insulin dosage.
摘要:
A method of extracting and analyzing bodily fluids from a patient at the point of care for the patient is provided. The method comprises establishing fluid communication between an analyte detection system and a bodily fluid in the patient. A portion of the bodily fluid is drawn from the patient. A first component of the bodily fluid is separated from the drawn portion, while the analyte detection system remains in fluid communication with the patient. The analyte detection system analyzes the first component to measure a concentration of an analyte in an accurate and timely manner.

An embodiment of a system for analyzing a body fluid of a patient comprises a fluid transport network that has a patient end configured to provide fluid communication with the body fluid in the patient and a fluid delivery point spaced from the patient end. A pump system is coupled to the fluid transport network. The pump system has an infusion mode in which the pump system is operable to pump an infusion fluid toward the patient end of the fluid transport network. The pump system has a draw mode in which the pump system is operable to draw the body fluid from the patient into the fluid transport network through the patient end. The system further comprises at least one fluid holder located near the fluid delivery point of the fluid transport network. The at least one fluid holder is positioned to receive a portion of the body fluid delivered to the delivery point by the fluid transport network. A laboratory-grade fluid analyzer is configured to receive the fluid holder and to measure at least one analyte in the portion of the body fluid.
