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.

A body fluid sensing device with a body fluid capture structure and a body fluid measurement sensor positioned in the body fluid capture structure. A capacitance sensor is coupled to the body fluid measurement sensor. The capacitance sensor is used to assist in the positioning of a body part relative to the body fluid capture structure.

The present invention extends to a closed IV line draw system which may be used with a PIVC or another vascular access device to collect blood samples. The closed IV line draw system consists of various integrated components that allow the system to remain closed during the blood collection process. In this way, the closed IV line draw system simplifies the blood collection process and reduces the risk of contamination to the PIVC or other vascular access device.

A lancing device has a domed structure that can be depressed by application of a force by a user's finger so as to expose the tip of a needle. The domed structure is configured to move from a non-depressed state to a depressed state in a manner that allows for the piercing of the user's finger. The domed structure may then recoil to its original, non-depressed position upon the user ceasing to apply the force. Other embodiments of a lancing device are disclosed.

A blood lancet device comprising a housing having one end formed as an opening; a sliding sleeve having one end extending from the opening to the outside of the housing; a blood lancet including a needle body and a needle tip arranged at one end of the needle body, the sliding sleeve being bushed at the outside of the housing, said blood lancet adapted to move relative to the sliding sleeve so as to expose the needle tip at the opening; and a biasing member having one end securely fixed with another end of needle body.

An apparatus includes a housing, a fluid reservoir, a flow control mechanism, and an actuator. The housing defines an inner volume and has an inlet port that can be fluidically coupled to a patient and an outlet port. The fluid reservoir is disposed in the inner volume to receive and isolate a first volume of a bodily-fluid. The flow control mechanism is rotatable in the housing from a first configuration, in which a first lumen places the inlet port is in fluid communication with the fluid reservoir, and a second configuration, in which a second lumen places the inlet port in fluid communication with the outlet port. The actuator is configured to create a negative pressure in the fluid reservoir and is configured to rotate the flow control mechanism from the first configuration to the second configuration after the first volume of bodily-fluid is received in the fluid reservoir.

A system for confirming acquisition of a fluid sample is provided. The system includes a wearable electronic device configured to be worn by a user. The device has a housing, at least one imaging sensor associated with the housing, a data transmission interface for sending data to or receiving data from an external electronic device, a microprocessor for managing the at least one imaging sensor and the data transmission interface, and a program for acquiring and processing images acquired by the at least one imaging sensor. The system further includes a sampling device for collecting a fluid sample in a sample container and at least one identification tag attached to or integrally formed with the sampling device or sample container. The at least one identification tag includes or is associated with a tracking code.

A precise arterial blood sampling device comprising a pen cap and a pen container which comprises a front pen container and a rear pen container, wherein: a first piezoelectric sensor sensing column is horizontally fixed to the front pen container, a horizontal slide rail is provided on the front pen container, a second piezoelectric sensor sensing column is provided on the horizontal slide rail, splines are provided on the second piezoelectric sensor sensing column, an elongated groove is formed on the front pen container, and a sensing column extending/retracting control wheel fitting with the splines is provided in the elongated groove; and a control chip, a needle ejection mechanism, a display screen, and a switch are provided inside the rear pen container, and the first piezoelectric sensor sensing column, the second piezoelectric sensor sensing column and the display screen are connected to the control chip respectively.

An apparatus includes a housing, defining an inner volume, and an actuator mechanism movably disposed therein. The actuator mechanism is configured to be transitioned from a first configuration to a second configuration to define a pre-sample reservoir fluidically couplable to receive a pre-sample volume of bodily-fluid via an inlet port of the housing. The actuator mechanism is movable from a first position to a second position within the housing after the pre-sample reservoir receives the pre-sample volume such that the housing and the actuator mechanism collectively define a sample reservoir to receive a sample volume of bodily-fluid via the inlet port. The outlet port is in fluid communication with the sample reservoir and is configured to be fluidically coupled to an external fluid reservoir after the sample volume is disposed in the sample reservoir to transfer at least a portion of the sample volume into the external fluid reservoir.
