Fluid delivery and infusion devices, and methods of use thereof
A medical device comprising an infusion device comprising a fluid reservoir to contain a therapeutic fluid and a transcutaneous access tool fluidly coupled to the fluid reservoir, the transcutaneous access tool configured to deliver the therapeutic fluid subcutaneously to a patient; wherein the infusion device operates in a stand-by mode prior to the therapeutic fluid being introduced into the fluid reservoir; wherein the infusion device operates to deploy the transcutaneous access tool within a predetermined deployment time period upon filling the fluid reservoir to a predetermined fill level with the therapeutic fluid.
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 as disposables, thereby allowing accurate and safe use and convenient maintenance.
Dual needle delivery system that connects and deploys needles of a medication delivery device
A medication delivery patch that is applied to the skin and activated to deliver a medication or other fluid into or through the skin. The patch may be completely mechanically driven, with no electronic components, for low cost, safety, and reliability. Pressing an activation button may set in motion a sequence of mechanical events that result in a needle exiting the patch into the skin of the user, and flow of fluid from an internal pouch in the patch into the user. When delivery is complete, another sequence of mechanical events may occur to retract the needle from the skin and stop the flow of fluid, and to show a visible indicator that delivery is complete. The patch may contain a fluid channel, such as a microfluidic channel, that controls the rate and time of delivery; this channel can be configured or selected for different medications or use cases.
METHODS AND APPARATUS FOR SELECTIVELY OCCLUDING THE LUMEN OF A NEEDLE
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.
Injection Assembly Apparatuses, Systems, and Methods
An injection port assembly may comprise a support body having a receptacle associated with a passage through the support body. The receptacle may have at least one recess in an end surface of the receptacle. The receptacle may have a plurality of retainer members. The assembly may further comprise a peripheral rim rib about a periphery of the support body and a number of additional ribs extending from the receptacle to the peripheral rim rib. The assembly may further comprise a delivery assembly coupled within the receptacle via the retainer members. The delivery assembly may have a cannula extending through the passage. The delivery assembly may have an injection receiving volume within the delivery assembly in fluid communication with a lumen of the cannula but otherwise fluidically sealed by a self-sealing barrier. There may be a sole externally accessible portion of the barrier aligned with an axis of the lumen.
INFUSION SET AND INSERTER ASSEMBLY APPARATUSES, SYSTEMS, AND METHODS
An inserter assembly may comprise a casing having an open end and a closed end. The inserter assembly may further comprise a first unit at least partially within the casing movable relative to the casing. The first unit may comprise a device base. The first unit may further comprise a sharp. The first unit may further comprise a body configured to displace in tandem with the sharp at least during displacement of the sharp from a forward to a retracted state. The first unit may further comprise a bias member configured to displace the body toward the closed end and displace the sharp to the retracted state when a release latch is transitioned from an engaged to a released state. One of the casing and the body may include a projection which engenders tilting of the body as the body and sharp are displaced by the bias member.
Subcutaneous infusion needle stick prevention device using needle hub retraction
A needle stick prevention device (10, 110) includes a needle shield (20, 120) for selectively covering a distal end of a needle (41, 141). A needle hub (40, 140) is movably received within the needle shield (20, 120). The needle hub (40, 140) includes a proximal end (42, 142), a distal end (46, 146), a needle (41, 141) fixedly connected to the distal end of the needle hub (40, 140), and a plurality of ribs (54) or a cylinder (150) disposed between the proximal and distal ends. An actuation button movably received in a transverse opening of the needle shield (20, 120) to engage the needle shield (20, 120), the needle hub (40, 140) and a medical device. A spring (58, 158) is disposed between the needle hub (40, 140) and actuation member to automatically retract the needle (41, 141) into the needle shield (20, 120).
Fluid delivery device having an insertable prefilled cartridge
A fluid delivery device includes a housing having a bottom surface configured to be coupled to the skin surface. The fluid delivery device includes a cartridge prefilled with a fluid and configured to be inserted into the housing. The cartridge has a septum configured to be generally perpendicular to the bottom surface when the cartridge is inserted in the housing. The fluid delivery device includes a needle assembly that has a needle that includes a fluid coupling end and a delivery end. The fluid coupling end of the needle is fluidly disengaged from the cartridge in an initial position. The delivery end of the needle extends past the plane of the bottom surface and the fluid coupling end of the needle extends through the septum in a deployed position.
Catheter system with extendable extension tube
A catheter system may include a catheter adapter having a distal end, a proximal end, and a lumen extending therebetween. The system may include a catheter tube extending distally from the catheter adapter. The system may include an extension tube coupled to the proximal end of the catheter adapter. The extension tube may be extendable. The system may include a locking mechanism coupled to the extension tube and removably coupled to the proximal end of the catheter adapter. The system may include a needle hub removably coupled to a proximal end of the extension tube and an introducer needle extending through the catheter tube. A proximal end of the introducer needle may be secured within the needle hub.
