A sample tube holder (40) includes an elongated body (42) with an open end (46) suitable for receiving sample vials. A lid (50) is pivotally attached to body and movable to a position over the open end. The lid includes an aperture (62) that is configured to allow a portion of a vascular access needle assembly to extend through the aperture while an access needle (20) and needle protector (34) portion of the assembly are captured and confined within the body to afford added protection against accidental needle sticks.

An extension set is configured to improve patency of a vascular access device. An extension set may include a probe that can be selectively advanced through a vascular access device to which the extension set is connected. The extension set may include an integrated device, or may be configured to receive a device, for collecting blood from or injecting a fluid into a patient's vasculature. Because the probe can be selectively advanced into the patient's vasculature, a blood collection or fluid injection can be performed via the vascular access device even when an occlusion has formed that is blocking the fluid pathway through the vascular access device.

This disclosure provides equipment and processes for blood glucose management. Embodiments may comprise a lancet device that includes a base that supports a lancet and a cover. The cover can move controllably from an un-depressed position to a depressed position when a predetermined force is applied. The cover can provide access to the lancet in the depressed position. In another aspect, a biological test kit may include a reusable module and a disposable module. The disposable module may include one or more lancet devices such as that described above to collect a biological sample, one or more strip stations supporting biological strips and a disposable module connector. The reusable module may support measuring equipment to measure a property of the biological sample and a reusable module connector that engages removably with the disposable module connector.

A point-of-care diagnostic system that includes a cartridge and a reader. The cartridge can contain a patient sample, such as a blood sample. The cartridge is inserted into the reader and the patient sample is analyzed. The reader contains various analysis systems, such as a magneto-optical system that measures a light transmission differential through the patient sample in varying magnetic fields. The reader can process data from the various patient sample analysis to provide interpretative results indicative of a disease, infection and/or condition of the patient.

Disclosed is a lancet device including: a body, having a first end and a second end; a head cap, wherein the first end of the head cap is provided with a needle outlet hole, and the second end of the head cap is connected to the first end of the body; a tail cap, wherein the first end of the tail cap is connected to the second end of the body, and the tail cap is provided with a first spring connecting portion, or the first spring connecting portion is provided in the tail cap; a needle core assembly, at least a part of which is axially guided and located in the body, wherein the needle core assembly includes a needle seat and a blood taking needle, the blood taking needle is provided on the needle seat, and the needle tip of the blood taking needle is adapted to extend out from the needle outlet hole; a trigger assembly, having a driving core acting on the needle seat, wherein the driving core is adapted to drive the needle seat to move toward the needle outlet hole based on a trigger operation, and the driving core is provided with a second spring connecting portion; a driving spring, the both ends of which respectively abut against or are connected with first and second spring connecting portions, wherein the driving spring is located between the first and second spring connecting portions; and an elastic force adjustment unit for adjusting the axial distance between the first and second spring connecting portions to adjust the trigger elastic force of the driving spring.

A needle assembly can include a needle and a proximal compartment forming a reservoir for collecting blood that flows through an inner lumen of needle. The needle assembly may also include a needle tip shield for capturing a sharpened distal tip of the needle. The needle tip shield can form a fluid pathway through which blood contained within the reservoir is expelled. The volume of the reservoir can be reduced to cause blood to be expelled from the needle tip shield such as by compressing the proximal compartment or a plunger connected to the proximal compartment or by moving a plunger into the reservoir. The fluid pathway of the needle tip shield can either be the same pathway through which the sharpened distal tip is withdrawn into the needle tip shield, or can be a separate pathway.

A fluid transfer device for parenterally transferring fluid to and/or from a patient includes a housing, a needle, and an occlusion mechanism. The housing defines a fluid flow path and is couplable to a fluid reservoir. The needle has a distal end portion that is configured to be inserted into the patient and a proximal end portion that is configured to be fluidically coupled to the fluid flow path of the housing, and defines a lumen therebetween. The occlusion mechanism selectively controls a fluid flow between the needle and the fluid flow path. The occlusion mechanism includes an occlusion member that is movable between a first configuration where the lumen of the needle is obstructed during insertion into the patient and a second configuration where the lumen of the needle is unobstructed after the needle has been inserted into the patient allowing fluid transfer to or from the patient.

A point-of-care diagnostic system that includes a cartridge and a reader. The cartridge can contain a patient sample, such as a blood sample. The cartridge is inserted into the reader and the patient sample is analyzed. The reader contains various analysis systems, such as a magneto-optical system that measures a light transmission differential through the patient sample in varying magnetic fields. The reader can process data from the various patient sample analysis to provide interpretative results indicative of a disease, infection and/or condition of the patient.

This disclosure generally relates to medical devices that include a transmitter assembly positioned on top of a sensor assembly. A sensor assembly includes a sensor base having a bottom surface and a top surface having an interface. The interface accommodates a sensor stack that includes at least one sensor head having electrical contact pads connected to an elastomeric connector. The sensor assembly further includes a mounting base having a first side that attaches to the bottom surface of the sensor base, and a second side that adheres to a patient's skin. A transmitter assembly includes a transmitter shell and a transmitter cap having an interface that engages with the sensor base. Also, the transmitter assembly includes electrical contacts disposed on the transmitter cap that connect with the electrical contact pad(s) of the sensor assembly.
