An apparatus includes a catheter, an introducer having a first member and a second member, a locking mechanism coupled to a distal end of the first member and configured to couple the introducer to a peripheral intravenous line, and an actuator coupled to the catheter. The actuator is configured to move from a first configuration, in which the catheter is disposed within the introducer, toward a second configuration to move the second member to a distal position relative to the first member. A portion of a guide of the second member being distal to the first member when the second member is in the distal position. The actuator is configured to move relative to the second member to be placed in the second configuration when the second member is in its distal position such that the catheter is disposed within and extending past an end of the peripheral intravenous line.

Fluid collection/injection device comprises a body having a front end, a back end, and a main hollow section arranged between the front and back ends and a needle hub securing section arranged on the front end and being structured and arranged to receive therein a needle member. The fluid collection/injection device is structured and arranged to utilize at least an operational mode, an operational mode, and a post-use mode. In the installation mode, the needle member is coupled to the body via the needle hub securing section. In the operational mode, fluid passes through the needle member and into or out of a receptacle inserted into the main hollow section.

Embodiments of the present invention provide magnetic lancet devices and methods for driving a lancet. For example, a magnetic lancet device may include a driving mechanism having a plurality of magnets and a lancet coupled to the driving mechanism. A magnetic interaction between the plurality of magnets is configured to drive the lancet from an engaged position to a penetrating position.

An ejection-type safety intravenous needle includes a sheath, a hub, a cannula fixed on the hub, and a base. An accommodation cavity is formed in the base. The hub is fixed in the accommodation cavity, and the cannula is exposed outside of the accommodation cavity. The sheath encloses the cannula, and a bottom of the sheath is located in the accommodation cavity and provided with a first limiting structure. A second limiting structure cooperating with the first limiting structure is provided at a top of the accommodation cavity. An elastic element is provided in the accommodation cavity, and the elastic element abuts against a bottom end of the sheath. A top and a bottom of the base are provided with a first clamping structure and a second clamping structure, respectively. A third clamping structure cooperating with the first clamping structure and the second clamping structure is provided on the sheath.

A retractable needle assembly includes a housing having a sidewall defining a hollow bore, and an elongate plunger, the distal end of the plunger forming a reservoir within the hollow bore for containing a fluid therein. The plunger is adapted for slideable movement within the hollow bore. The assembly includes a hub disposed within the hollow bore and at least partially supporting a cannula therewith, and a needle retraction member engaged with the hub for manually selectable advancement with respect to a portion of the housing. The needle retraction member may be advanced from an initial position in which at least a portion of the needle is disposed outside the housing, to a retracted position in which the needle is fully surrounded by the housing. The elongate plunger may be advanced about the hub for extracting the fluid into the reservoir or expelling the fluid from the reservoir.

An apparatus includes a catheter, an introducer having a first member and a second member, a locking mechanism coupled to a distal end of the first member and configured to couple the introducer to a peripheral intravenous line, and an actuator coupled to the catheter. The actuator is configured to move from a first configuration, in which the catheter is disposed within the introducer, toward a second configuration to move the second member to a distal position relative to the first member. A portion of a guide of the second member being distal to the first member when the second member is in the distal position. The actuator is configured to move relative to the second member to be placed in the second configuration when the second member is in its distal position such that the catheter is disposed within and extending past an end of the peripheral intravenous line.

A disposable lancing device contains: a first casing, a second casing, and a needle holder. The first casing includes a close segment, an open segment, a slideway, two tilted contact faces, a fixing portion, two recesses, and two push fringes. The second casing includes an accommodation chamber, two limitation extensions, and multiple drive protrusions. A forcing face is defined on the second casing opposite to the two limitation extensions, and a through hole is defined on a center of the forcing face. The through hole has a protruded rib. The needle holder includes a collection needle having a syringe needle, and the needle holder further includes a trigger spring, a return spring, and two symmetrical flexible wings. The two symmetrical flexible wings include two driving segments configured to abut against the two symmetrical flexible wings to flexibly retract inward by using the two tilted contact faces.

A blood collection item comprises a furan resin selected from the group consisting of: poly (ethylene 2,5-furan dicarboxylate) (PEF), poly (butylene 2,5-furan dicarboxylate) (PBF), poly (trim ethylene furan dicarboxylate) (PTF), poly (propylene 2,5-furandicarboxylate) (PPF), and poly (neopentyl 2,5-furandicarboxylate) (PNF). The item may be a syringe having an injection-molded plunger and barrel, a blood collection tube, or a tube holder.

A needle assembly is disclosed. The needle assembly includes a housing having a flash chamber, and having a distal end and a proximal end engageable with a specimen collection container. The assembly includes a cannula having a patient end, a non-patient end, and a sidewall extending therebetween defining a cannula interior. The patient end of the cannula projects at least partially from the distal end of the housing, and the cannula interior is in fluid communication with the flash chamber. The assembly further includes a shield restrainably engaged with a portion of the housing and axially transitionable over the patient cannula from a retracted position in which the patient end is exposed, to an extended position in which the patient end is shielded by at least a portion of the shield, wherein at least a portion of the flash chamber is visible in the retracted position.

An intravenous catheter introducer for medical use having a body, a frontal attachment that is disposed in transverse sliding engagement with a front part of the body, a hub tube assembly that is releasably supported by the frontal attachment, and a retractable catheter insertion needle and needle holder that are biased rearwardly by a spring offset laterally from the needle axis, whereby lateral repositioning of the body relative to the frontal attachment following vascular insertion moves a needle retraction cavity disposed inside the body into substantial coaxial alignment and causes the needle holder to be retracted into the needle retraction cavity.
