An apparatus for insertion of a medical device in the skin of a subject is provided, as well as methods of inserting medical devices. Embodiments include removing a substantially cylindrical cap from an inserter to expose a substantially cylindrical sleeve, removing a cover from a substantially cylindrical container holding sensor components, and fitting the sensor components into the inserter.

A syringe apparatus (10) is provided which comprises a syringe portion having a syringe (12) or holder (24) adapted to receive a syringe (12) therein, the syringe portion having a rear grip (38) for seating in or against a user's hand and a front grip (40) formed at or adjacent to a tip end (22) of the syringe portion; and a movable member (30) engagable with a plunger (16) of the said syringe (12), the movable member (30) having a finger grip (32) at or adjacent to a tip end (22) thereof, the movable member (30) being engaged with the syringe portion and configured to move relative to the rear grip when a user applies a force at the finger grip (32); wherein the front and rear grips (40, 38) are formed as lateral projections (40a, 40b; 38a, 38b) with respect to the movable member (30).

A push-type blood collection needle includes a housing having an accommodating cavity therein, a rear cover and a needle body disposed in the accommodating cavity. The rear cover is movably disposed on the housing, and the rear cover has a supporting leg extending into the accommodating cavity. The needle body is provided with a rib. The accommodating cavity is internally provided with a projecting part that cooperates with and blocks the bottom of the rib. The supporting leg is provided with a stopper that cooperates with and blocks the side wall of the rib. And an elastic member is disposed between the needle body and the rear cover.

An adapter for a syringe having a barrel, a pair of syringe flanges secured to the barrel, and a plunger with a plunger top, the plunger being slidably disposed within the barrel, the adapter having a barrel guide configured to movably surround the barrel, a plunger lock configured to secure the plunger to the adapter, a support body disposed between and associated with the barrel guide and the plunger lock and a front grip associated with the barrel guide. By compressing the syringe flanges and the front grip toward each other, the barrel may travel forward through the barrel guide, thus drawing fluid into the syringe. The adapter, by allowing a compression force to be used to draw a fluid into the syringe, allows an individual to quickly and easily perform a blood draw or other fluid drawing operation with one hand, removing the need for a second user.

Exemplary embodiments provide automatic injection devices, housing components for automatic injection devices and methods for fabricating the same. An exemplary housing of an automatic injection device may be overmolded with one or more gripping surfaces to facilitate gripping and manipulation of the automatic injection device by a user when performing an injection. In an exemplary embodiment, an overmolded left gripping surface may extend along a left side of the housing and an overmolded right gripping surface may extend along a right side of the housing opposite to the left side.

A catheter system may include a catheter lumen, first and second electrodes, and a sensor in communication with the first and second electrodes. The sensor may be configured to detect at least one of: a bulk volume of blood within a blood vessel and extravasation of a drug from the blood vessel into soft tissue adjacent the blood vessel. Other catheter systems may include a catheter lumen and a sensing chip coupled to the catheter lumen. The sensing chip may be configured to detect at least one of: a bulk volume of blood within a blood vessel and extravasation of a drug from the blood vessel into soft tissue adjacent the blood vessel.

The present disclosure generally relates to receiving bodily fluid through a device opening. In one aspect, the device includes an interface that facilitates piercing of skin and/or withdrawal of fluid from the skin. The skin may be subjected to vacuum from a vacuum source.

A blood draw device including an introducer and an actuator. The introducer has a proximal end portion, a distal end portion, and an inner volume, and includes a top surface having a first portion of a first length and a second portion of a second length. The first portion may have a smooth surface along the first length and the second portion has a plurality of ridges along the second length. The actuator includes an exterior portion positioned above the top surface and an interior portion positioned within the inner volume, wherein the exterior portion of the actuator includes an engagement member and a downwardly-extending tab projecting below the engagement member such that the downwardly-extending tab of the actuator may contact at least the plurality of ridges of the second portion of the introducer to provide at least one of tactile and audible feedback to a user.

A biological fluid collection system that receives a sample and provides flow-through blood stabilization technology and a precise sample dispensing function for point-of-care and near patient testing applications is disclosed. A biological fluid collection system of the present disclosure is able to effectuate distributed mixing of a sample stabilizer within a blood sample and dispense the stabilized sample in a controlled manner. In this manner, a biological fluid collection system of the present disclosure enables blood micro-sample management, e.g., passive mixing with a sample stabilizer and controlled dispensing, for point-of-care and near patient testing applications.
