A needle guide assembly for inserting a needle into the body of a patient in order to access a subcutaneous target, such as a vessel, is disclosed. In one embodiment, the needle guide assembly comprises a needle guide body that is configured to at least indirectly and removably attach to an image producing device, such as an ultrasound probe. The needle guide body defines at least first and second elongate guide channels. Each guide channel defines a unique insertion angle with respect to a longitudinal axis of the ultrasound probe. Further, each guide channel is configured to accept needles of differing gauges. In other embodiments other needle guide assemblies are disclosed that include multiple guide channels for inserting a needle at a variety of insertion angles into the patient's body. Related methods are also disclosed. In yet other embodiments, needle guide assemblies including needle stop features are disclosed.

A biopsy needle unit includes a biopsy needle and an elastically deformable safety tube for partially covering the biopsy needle inserted to a lumen extending in a longitudinal direction. A marker is arranged on the biopsy needle at a position protruding from an end portion of the safety tube on an opposite side of a needle tip of the puncture needle when the needle tip portion is accommodated in the lumen. The safety tube has portions in which the lumen is curved at least partially with respect to the longitudinal direction so that the safety tube is elastically deformed due to contact between an inner circumferential face of the lumen and an outer circumferential face of the biopsy needle when the biopsy needle is inserted to the lumen to cause frictional resistance between the inner circumferential face of the lumen and the outer circumferential face of the biopsy needle.

Described here are meters and methods for sampling, transporting, and/or analyzing a fluid sample. The meters may include a meter housing and a cartridge. In some instances, the meter may include a tower which may engage one or more portions of a cartridge. The meter housing may include an imaging system, which may or may not be included in the tower. The cartridge may include one or more sampling arrangements, which may be configured to collect a fluid sample from a sampling site. A sampling arrangement may include a skin-penetration member, a hub, and a quantification member.

The present disclosure relates to a fluid analyzing device that includes a sensing device for analyzing a fluid sample. The sensing device includes a microchip configured for sensing the fluid sample, and a closed micro-fluidic component for propagating the fluid sample to the microchip. The fluid sample can be provided to the micro-fluidic component via an inlet of the fluid analyzing device. And a vacuum compartment, which is air-tight connected to the sensing device, can create in the micro-fluidic component a suction force suitable for propagating the fluid sample through the micro-fluidic component.

A segmented safety cover may include a proximal segment combined with a needle hub; a needle cannula that extends from the proximal needle hub to a distal sharpened end; a distal end cap with a hollow bore through which the needle cannula passes; a centrally mounted toggle locking mechanism, separating the proximal needle hub from the distal end cap; the toggle locking mechanism is torsion spring assisted; a proximal cover segment is connected to the hub via a proximal hinge and a distal cover segment is connected to the end cap via a distal hinge; said proximal cover segment and said distal cover segment of said toggle locking mechanism being configured with abutting faces when the segmented safety cover is in a safety mode; and wherein the proximal hinge, abutting faces and distal hinge are in line in the safe mode.

A blood collection device to reduce hemolysis in a peripheral intravenous catheter system may include a distal end. The distal end of the blood collection device may include a male luer adapter, which may include a distal opening. The blood collection device may include a cannula in fluid communication with the male luer adapter. The cannula may include a distal end and a sharp proximal tip. The blood collection device may include an elongated neck disposed between the male luer adapter and the sharp proximal tip. The blood collection device may include a fluid pathway extending from the distal opening through the sharp proximal tip. A diameter of the fluid pathway may be constant. An entire length of the fluid pathway is represented by L, and the diameter of the fluid pathway is represented by D. D.sup.4/L may be equal to or less than a predetermined value.

The current invention is a syringe and swab system for a syringe having a plunger, a barrel, a needle hub, a needle, a needle safety cover, and a swab attached to the distal end of the needle safety cover for placing over an injection site to apply pressure and a vial for holding fluid that may be utilized with the swab.

Apparatus and methods pertaining to catheters used for the withdrawal of blood.

The present disclosure is directed to a needle assembly for drawing blood. The needle assembly can be a standalone or part of an over-the-needle medical device, such as an intravenous catheter. A blood collection device is attached directly or indirectly to the needle hub of the needle assembly and/or to a catheter hub, such as through a Y-site or adaptor connected to a tubing that is connected to the catheter hub. The needle is configured to access the vascular system to draw blood, which then passes to the blood collection device via the needle lumen, which has a tip having a discontinuity opening, an opening with a movable stem, or a shaft element with a lumen.

A blood collection apparatus is provided with a blood collection assembly including a casing tube including a forward nose, a plurality of connectors and a rear flange having a flexible projection, a plunger slidably disposed in the casing tube and including a forward plug and an elongated arm having a plurality of cavities, a blood collection tubes, an adapter assemblies each including a tube body, a first tube extending out of one end and insert into a related connectors of the casing tube, a second tube extending out of the end to insert into one of the blood collection tubes, and a butterfly needle assembly mounted to the nose of the casing tube. A pulling of the plunger moves the plug rearward and pivots the projection to engage in one cavity of the elongated arm and an orifice of the each related connectors is not blocked by the plug so as to flow blood from the tube casing to one of the blood collection tube via one connector and one adapter assembly.
