INJECTOR NEEDLE INSERTION RETRACTION ASSEMBLY
A needle insertor for a medicament delivery device is presented having a driver having a first part movably arranged within the case and a second part connected to the base, a needle assembly movably held by the first part in the case, a rotator arranged in the case and configured to engage the first part for moving the driver, an energy accumulation member configured to interact with the rotator for applying a rotational force on the rotator, a movable stop arranged on the base and configured to interact with the rotator for preventing the rotator from rotating. The first part has a first position where the needle assembly is held inside the case, a second position where the needle portion is positioned outside the case after being moved to pass through the injection site end, and a third position where the needle portion is positioned inside the case.
Adhesive encased protective caps for needle devices and related methods
A needle assembly includes a catheter hub, a catheter tube extending distally from the catheter hub, and a needle hub having a needle having a needle tip extending out the catheter tube. A protective cap is positioned with the catheter hub and covers the catheter tube and the needle tip. The protective cap has a casing having a casing body, a first opening at a proximal end of the casing body, a proximal cavity having the needle tip and the catheter tube located in the proximal cavity, a second opening at an end opposite the first opening and opening into a distal cavity, and a rim at the second opening. A lid is removably attached to the rim at the second opening to seal a solution inside the distal cavity. The solution is dispensable from the distal cavity following separation of the lid from the rim.
EXTENDED DWELL AND MIDLINE CATHETERS AND RELATED METHODS
Extended dwell catheter assemblies each with a housing having an interior having a catheter assembly located therein, which can include a catheter tube and a needle. The catheter tube of the catheter assembly can be placed into a vein of a patient, with or without a guidewire, and then the extended dwell catheter assembly can be activated to separate into two or more housing components or by opening a gate to enable separation of the catheter assembly from the housing. A needle guard can be included to cover the needle tip of the needle from unintended needlesticks.
Needle assembly with flexible catheter nose for diagnostic sampling of fluid
A needle assembly for sampling fluid from a patient including a needle guard, an insertion needle, and a needle housing. The distal end of the needle guard includes a nose portion and a flexible nose extension defining a fluid collection reservoir. The proximal end of the needle guard includes a push feature. The insertion needle has a sharpened distal tip, a proximal needle end and a shaft defining a lumen extending therebetween. The needle housing is operably coupled to the proximal needle end and is slideably coupled to the needle guard. The needle housing includes a flash chamber including a wall defining a cavity. The cavity is in fluid communication with the lumen of the insertion needle and is sealed at one end by a gas permeable flash plug. The push feature selectively engages the flash plug to divert captured bodily fluids to the fluid collection reservoir for sampling.
Invisible needle
The invention relates to an inserter for an infusion set for intermittent or continuous administration of a therapeutical substance, such as e.g. insulin. The inserter comprises a needle hub comprising an insertion needle and two spring units assuring automatic insertion and automatic retraction of the insertion needle. The inserter comprises a housing (1), a carrier body (2) carrying an infusion part (8), a needle hub (3), a first moving unit (4) bringing the carrier body (2) to a forward position and a second moving unit (5) bringing the carrier body (2) to a retracted position. The inserter is characterized in that it has means for activation which should be activated at least once in order to bring the carrier body (2) from a retracted to a forward position, and back from the forward to the retracted position.
Splittable Needle for Catheter Placement System
Advanced catheter placement systems require disengaging a needle from the guidewire without disturbing a position of the guidewire within the vasculature. Embodiments include withdrawing the needle proximally and drawing the needle over a splitter system that includes a splitter wedge. The splitter system separates the needle along a longitudinal axis. A portion of the guidewire can then pass between a first portion and a second portion of the needle, allowing the needle to disengage the guidewire. A catheter disposed on a proximal portion of the guidewire can then be advanced thereover into the vasculature. A needle safety system can adhere a puncture-resistant adhesive tape to the split portions of the needle. The tape can encapsulate the portions of the needle mitigating any damage or trauma caused by sharpened edges of the needle portions.
CATHETER, CATHETER ASSEMBLY, AND CATHETER SYSTEM
A catheter includes: a shaft to be inserted into a blood vessel, the shaft being flexible and having a tubular shape. The shaft comprises: a light emitting portion that is located at a distal end portion of the shaft and is configured to emit near-infrared light by being irradiated with light, and a non-light emitting portion that extends from the light emitting portion toward a proximal end side of the shaft and does not emit the near-infrared light. A length of the light emitting portion in an extending direction of the shaft is six times or less an outer diameter of the non-light emitting portion in an extending direction of the shaft.
System for color-coding medical instrumentation and methods of use
A system comprising a biopsy needle device comprising a cannula comprising a distal end configured to sever a tissue sample, and a trocar disposed within the cannula comprising a notch configured to retain a tissue sample, wherein at least one of the cannula and the trocar is divided into at least two segments including different echogenic coatings, an ultrasound probe, and a processor configured and arranged to collect images from the ultrasound probe and color code the at least two segments based on at least one characteristic relating to different echogenic coatings, surface textures, surface contours and dimensions of the biopsy device.
NEUROVASCULAR PUNCTURE-AVOIDANT SHEATH
A device and method for a guidance sheath is provided which is configured to prevent laceration or puncture of nerves, blood vessels and surrounding tissue, during positioning of a coaxially located needle employed for various medical procedures, such as, the administration of an anesthetic blockade, neuromonitoring, electromyography or a therapeutic intervention.
NEEDLE COVER RETENTION
A catheter assembly may include a catheter adapter, which may include a body and a nose extending distally from the body. The nose may be generally cylindrical. A strain relief rib may be disposed on the nose. The strain relief rib may be constructed of a flexible material. The catheter assembly may also include a needle secured within the catheter adapter and extending distally beyond the nose. The catheter assembly may further include a needle cover, which may be removably coupled to the nose of the catheter adapter. An inner surface of the needle cover may be smooth and may contact the strain relief rib.
