A medical device having a frontal attachment and a connector housing having or attachable to an associated medical apparatus, the frontal attachment slidably engaging the connector housing and having a forwardly projecting, rearwardly biased needle and a needle retraction assembly, and the connector housing having a needle retraction cavity laterally offset from the needle in a first position, the needle retraction cavity being selectively movable relative to the frontal attachment following use to reposition the needle retraction cavity into alignment with the needle to permit retraction.

A medical device for the separation of a concentrate enriched with cells from a biological fluid, in particular a concentrate of stromal or stem cells from medullar aspirate or venous blood, comprises: a treatment container for receiving and treating the biological fluid for the purposes of its separation into a number of fractions; a first collection container, for receiving a first fraction of the fluid, in particular a fraction poor in said cells; a second collection container, for receiving a second concentrated fraction of the fluid enriched with said cells; a deviator valve having a first way connected or prearranged for connection to the treatment container, a second way connected or prearranged for connection to the first collection container, and a third way connected or prearranged for connection to the second collection container; a first line for connection of the treatment container to the first way of the deviator valve, a second line for connection of the first collection container to the second way of the deviator valve, and a third line for connection of the second collection container with the third way of the deviator valve.

The treatment container is a syringe container with a plunger having a plunger stem associated in a releasable way to a corresponding plunger head, and the first connection line comprises a first transparent tube, in particular a flexible transparent tube, and at least one of the second and third connection lines preferably comprises a second flexible tube. At least one connection line, or each connection line, further comprises: at least one respective hydraulic connector, for separable connection of a corresponding tube to the corresponding container and/or to the corresponding way of the deviator valve; and at least one automatic-closing or one-way valve.

A system for increasing rates at which fluids may be manually forced through injection/aspiration elements, such as catheters and needles, includes the injection/aspiration elements, as well as a syringe including a pair of crossed handles, one associated with the barrel of the syringe, the other associated with the plunger of the syringe, to provide a mechanical advantage. The system may include and injection/aspiration element of small (e.g., 0.052 inch or smaller) inner diameter and small outer diameter (e.g., 5 French or less). Such systems enable the use of a single hand to hold and operate a syringe in a variety or procedures, including angiography, angioplasty, discography, glue/cement injection, and a variety of aspiration procedures (e.g., biopsy, sampling, media removal, etc.).

Disclosed is a centrifugable syringe and syringe components for use in blood fractionation. Also disclosed is a method of blood fractionation using the syringe. The syringe comprises a substantially transparent barrel, a substantially transparent, elongated delineation neck, a plunger for drawing blood into and expelling blood from the barrel, and an adapter attached to the neck for enabling releasable connection of a selected device over an inlet/outlet opening in the neck. The delineation neck extends away from a distal end of the barrel. The barrel and the neck have respective axial bores in fluid flow communication with each other, the cross sectional area of the bore in the delineation neck being substantially less than the cross sectional area of the bore in the barrel. The selected device may be one of various devices including a capping device sealing the inlet/outlet opening of the neck, a needle device used during withdrawal of blood from a subject through the neck, or a hose device used to carry away delineated blood fractions from the syringe through the neck.

The present invention relates to a sensor applicator assembly for a continuous glucose monitoring system and provides a sensor applicator assembly for a continuous glucose monitoring system, which is manufactured with a sensor module assembled inside an applicator, thereby minimizing additional work by a user for attaching the sensor module to the body and allowing the sensor module to be attached to the body simply by operating the applicator, and thus can be used more conveniently. A battery is built in the sensor module and a separate transmitter is connected to the sensor module so as to receive power supply from the sensor module and be continuously used semi-permanently, thereby making the assembly economical. The sensor module and the applicator are used as disposables, thereby allowing accurate and safe use and convenient maintenance.

An instrument advancement device includes a housing comprising a fluid path, a distal end, and a proximal end, an instrument disposed within the housing, an advancement element, where in response to movement of the advancement element with respect to the housing, the instrument is configured to advance distal to the distal end of the housing, a small sample dispense device connected to the proximal end of the housing, and a blood collection device connected to a proximal end of the small sample dispense device. The blood collection device is configured to receive an evacuated blood collection container, where the small sample dispense device is detachable from the housing and configured to dispense a blood sample.

An instrument advancement device may include a housing comprising a distal end and a proximal end; an instrument disposed within the housing; an advancement element, wherein in response to movement of the advancement element with respect to the housing, the instrument is configured to advance distal to the distal end of the housing, and a blood sample collection tube inserted into the distal end of the housing, wherein the blood sample collection tube is configured to receive a small volume blood sample.

A syringe-based device includes a housing, a pre-sample reservoir, and an actuator. The housing defines an inner volume between a substantially open proximal end portion and a distal end portion that includes a port couplable to a lumen-defining device. The pre-sample reservoir is fluidically couplable to the port to receive and isolate a first volume of bodily fluid. The actuator is at least partially disposed in the inner volume and has a proximal end portion that includes an engagement portion and a distal end portion that includes a sealing member. The engagement portion is configured to allow a user to selectively move the actuator between a first configuration such that bodily fluid can flow from the port to the pre-sample reservoir, and a second configuration such that bodily fluid can flow from the port to a sample reservoir defined at least in part by the sealing member and the housing.

An ergonomic suction syringe and method for performing medical procedures in which suction is generated and can be delivered to a medical device by a single-handed compression motion, with suction actuated by forward motion of a piston into a cylinder, and in which suction can be maintained essentially permanently once activated without any further effort by the operator, even hands-free.

Embodiments of a syringe-based device for procuring bodily fluid samples can include a housing having a port that can be coupled to a lumen-defining device for receiving bodily fluids, an actuator mechanism retained at least partially within the housing, the actuator mechanism including a pre-sample reservoir, a plunger operably coupled with pre-sample reservoir, a plunger cap, a plunger tube, a valve, a plunger seal, an a selectively attachable collection vial for capturing a bodily fluid sample.
