DEVICES AND METHODS FOR SYRINGE-BASED FLUID TRANSFER FOR BODILY-FLUID SAMPLING
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.
DEVICES FOR COLLECTING BIOLOGICAL SAMPLES
Disclosed herein are devices, apparatus, systems, methods and kits for collecting and storing a fluid sample from a subject. A device for collecting the fluid sample can include a housing comprising a recess having an opening, a vacuum chamber in the housing and in fluidic communication with the recess, and one or more piercing elements that are extendable through the opening to penetrate skin of the subject. The vacuum chamber can be configured for having a vacuum that draws the skin into the recess. The recess can be configured having a size or shape that enables an increased volume of the fluid sample to be accumulated in the skin drawn into the recess.
Sensor applicator assembly for continuous glucose monitoring system
The present it 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 aspsposables, thereby allowing accurate and safe use and convenient maintenance.
Syringe systems and methods for multi-stage fluid delivery
A syringe-based device includes a housing, the housing including a port, and an actuator mechanism including a first member and a second member configured to be movably disposed within the housing. The first member includes a syringe body and a plunger movably disposed within the syringe body and including a first plunger seal. The second member includes a second plunger seal defining a channel and a valve fluidically coupled with the channel of the second plunger seal. The device also includes a first fluid reservoir and a second fluid reservoir. The device transitions from a first configuration to a second configuration in which a first type of fluid in the first fluid reservoir is delivered through a port, to a third configuration in which a second type of fluid within the second fluid reservoir is delivered through the port.
Syringe and swab system
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.
Blood collection apparatus
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.
Fluid handling device having a spring mechanism
A fluid handling device includes a receiving container with a piston arranged therein in a displaceable manner, such that the volume of a fluid receiving reservoir may be changed by a displacement of the piston. In addition, the fluid handling device includes an actuation mechanism configured to displace a carrier bearing upon actuation of the former. Finally, the fluid handling device includes a spring mechanism configured to transfer a force from the carrier bearing to the piston so as to effect, in response to displacement of the carrier bearing in a first direction, a displacement of the piston within the receiving container such that a volume of the fluid reservoir is increased.
Devices and methods for syringe-based fluid transfer for bodily-fluid sampling
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.
BLOOD SAMPLER
A blood sampler includes a hollow transparent barrel including a reduced collection portion located at a front end thereof and terminating in a reduced coupling portion, an outlet defined in the coupling portion and a plurality of ribs spaced around and raised from an inside wall near an opposing rear end thereof, a piston axially movably fitted into the hollow transparent barrel and having a screw hole and peripheral ribs, a cap detachably capped onto the collection portion to seal the outlet, and a plunger having a screw rod located at a front end thereof and threaded into the screw hole of the piston for allowing movement the piston with the plunger. The hollow transparent barrel enables collecting blood sample from a patient, separating the collected blood sample into platelet-rich plasma, platelet-rich plasma and serum in a centrifuge and injecting the collected platelet-rich plasma into a patient body.
Vacuum assisted lancing system with elective vacuum release and method for blood extraction with minimal pain
A vacuum assisted lancing system for blood extraction can include a tubular body having a vacuum chamber, a lancing mechanism configured to removably couple with a lance, a vacuum mechanism including a piston slideably coupled within the body, a release mechanism for selectively holding the vacuum mechanism in an energized state, and an opening for allowing fluid communication between the vacuum chamber and an atmosphere surrounding the vacuum chamber. The system can include structure for selectively commencing dissipation of the vacuum and a fixed or adjustable depth controller. A method of manipulating a surface for blood extraction can include coupling the lancing system to the surface, blocking the opening, creating a vacuum, moving the lance coupler from a first position distal from the surface to a second position proximal to the surface, maintaining the vacuum for a period of time, and commencing dissipation of the vacuum by unblocking the opening.
