Method and apparatus for improving fluidic flow and sample capture
A body fluid sampling device for use on a patient includes at least one penetrating member positioned in the cartridge and a sample port for receiving a body fluid. A channel is coupled to the sample port and the sample chamber. At least a portion of the channel is a capillary channel positioned adjacent to the sample chamber. A mesh membrane is and provides that the body fluid contacts the channel regardless of an orientation of body fluid sampling device.
Systems and interfaces for blood sampling
The present invention generally relates to systems and methods for delivering and/or receiving a substance or substances such as blood from subjects. In one aspect, the present invention is directed to devices and methods for receiving or extracting blood from a subject, e.g., from the skin and/or from beneath the skin, using devices containing a substance transfer component (for example, one or more needles or microneedles) and a reduced pressure or vacuum chamber having an internal pressure less than atmospheric pressure prior to receiving blood. In some embodiments, the device may contain a snap dome or other deformable structure, which may be used, at least in part, to urge or move needles or other suitable substance transfer components into the skin of a subject. In some cases, for example, the device may contain a flexible concave member and a needle mechanically coupled to the flexible concave member such that the needle may be urged or moved into the skin using the flexible concave member. Other aspects of the present invention are directed at other devices for receiving blood (or other bodily fluids, e.g., interstitial fluid), kits involving such devices, methods of making such devices, methods of using such devices, and the like.
Method for manufacturing insertion guide needle for continuous blood glucose monitoring device
The present disclosure relates to a method for manufacturing an insertion guide needle for a continuous blood glucose monitoring device. The present disclosure provides a method for manufacturing an insertion guide needle for a continuous blood glucose monitoring device, by which: an insertion guide needle can be manufactured through a cutting process and a bending process of a needle raw plate, so that a complicated manufacturing process is unnecessary, and can thus be easily manufactured through a simple process; an enlargement incision part for continuous enlargement and incision, etc. can be conveniently manufactured through such a simple processing process, so that a manufacturing cost thereof can be reduced and also the size accuracy of the insertion guide needle can be improved; and, particularly, in a process of inserting the insertion guide needle into skin, the insertion guide needle can be brought into point contact with the skin to cut the skin, and then can continuously cut the skin in an enlarged manner, so as to minimize pains which may occur in the process of inserting the insertion guide needle into the skin, thereby alleviating the sense of repulsion or tension at the time of using the continuous blood glucose monitoring device.
Automated medical sample collection and testing for providing blood coagulation indication
A sample collection and testing device for analyzing blood is provided that includes a controller, a fluid flow pathway, a pump configured to move fluid through the fluid pathway, and an optical fluid measurement element configured to measure a light intensity of the fluid in the fluid flow pathway. The controller is configured to: start the pump to move a blood sample in the fluid flow pathway, receive a signal from the optical fluid measurement element indicating a detection of a leading edge of the blood in the fluid flow pathway, stop the pump to stop the moving of the blood in the pathway, receive a plurality of light intensity measurements from the optical measurement element, each light intensity measurement measured at a corresponding point of time, and provide a mapping of the light intensity measurements into an indication of a coagulation of the blood sample over a time period.
Devices, systems and methods for actuation and retraction in fluid collection
The disclosed apparatus, systems and methods relate to devices, systems and methods for the collection of bodily fluids involving a single-use actuation and retraction mechanism disposed within a collector.
METHOD FOR MANUFACTURING INSERTION GUIDE NEEDLE FOR CONTINUOUS BLOOD GLUCOSE MONITORING DEVICE
The present disclosure relates to a method for manufacturing an insertion guide needle for a continuous blood glucose monitoring device. The present disclosure provides a method for manufacturing an insertion guide needle for a continuous blood glucose monitoring device, by which: an insertion guide needle can be manufactured through a cutting process and a bending process of a needle raw plate, so that a complicated manufacturing process is unnecessary, and can thus be easily manufactured through a simple process; an enlargement incision part for continuous enlargement and incision, etc. can be conveniently manufactured through such a simple processing process, so that a manufacturing cost thereof can be reduced and also the size accuracy of the insertion guide needle can be improved; and, particularly, in a process of inserting the insertion guide needle into skin, the insertion guide needle can be brought into point contact with the skin to cut the skin, and then can continuously cut the skin in an enlarged manner, so as to minimize pains which may occur in the process of inserting the insertion guide needle into the skin, thereby alleviating the sense of repulsion or tension at the time of using the continuous blood glucose monitoring device.
Adjustable lancet and test cartridge for automated medical sample collection and testing
A test cartridge includes an adjustable lancet. The adjustable lancet is controlled by a controller. The adjustable lancet automatically detects a subject's finger, adjusts the lancet's height, pricks the finger to draw blood, moves a tube to collect the blood, moves the tube away from the finger, and empties the blood from the tube into a vial or receptacle. The adjustable lancet may include safety features to prevent the lancet to trigger when the subject's fingernail is facing the lancet, to control the amount that the lancet pierces the subject's finger, and/or to prevent the reuse of a test cartridge for multiple persons or multiple times by the same person. The adjustable lancet may include a massager wheel and/or a pressure bar to rub the subject's finger after the finger is pierced to facilitate drawing of the blood from the finger.
