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.

Provided is a lancing device including a casing, a launch part, and a bumper part wherein the bumper part comprises a needle body holder, a cylindrical bumper and bump spring; and a disposable painless lancet for use with the device. The disposable painless lancet and lancing device according to the present invention are figured such that a bump spring strikes the skin in advance before the needle penetrates the skin, disturbing the skin nerve, and such that a needle of the lancet can be allowed to be inserted only a certain depth of skin, thus the subject does not feel any pain at all.

The present invention relates to a sealed blood collection device for clinical blood testing, comprises a blood collector head, a blood storage device and a discharge mechanism, the blood storage device comprises a blood storage tank, a blood tank entrance disposed at a bottom of the blood storage tank, an extraction piston disposed inside the blood storage tank and a safety pull ring; an external thread is disposed at the upper side wall of the blood storage tank; the extraction piston comprises a rubber piston disposed at a bottom of the blood storage tank and fits against a chamber thereof, a piston rod connected to an upper part of the rubber piston, and a rotatable barrel disposed at an upper part of the blood storage tank and threaded to the blood storage tank, the rotatable barrel comprises a through hole therein; the piston rod penetrates through the through hole, a top end of the piston rod comprises a ring shaped limiter abut against an end surface of the rotatable barrel; a one way valve is disposed inside the blood tank entrance. The blood collection device of the present invention has a reasonable structure, is convenient to use, has good sealing effect, and can also prevent leaks and stings.

The invention regards a protective cap for a delivery system, said cap comprising a tip part releasably attached to a main part, wherein the tip part and the main part together form an elongated body with a closed tip end, and the main part comprises at least one means for assisting the use of the delivery system.

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 apparatus comprises a housing, a testing member rotatably mounted in the housing, a lancet protruding from an edge of the testing member and having a piercing end, and a cover configured to cover at least the piercing end of the lancet and to be displaced from the piercing end of the lancet during actuation of the testing member.

A needle assembly can include a needle and a proximal compartment forming a reservoir for collecting blood that flows through an inner lumen of needle. The needle assembly may also include a needle tip shield for capturing a sharpened distal tip of the needle. The needle tip shield can form a fluid pathway through which blood contained within the reservoir is expelled. The volume of the reservoir can be reduced to cause blood to be expelled from the needle tip shield such as by compressing the proximal compartment or a plunger connected to the proximal compartment or by moving a plunger into the reservoir. The fluid pathway of the needle tip shield can either be the same pathway through which the sharpened distal tip is withdrawn into the needle tip shield, or can be a separate pathway.

A vascular access device may include a housing, which may include a proximal end, a distal end, and a slot. The distal end of the housing may be configured to be coupled to a catheter assembly. The vascular access device may also include an instrument disposed within the housing. The instrument may include a catheter or a probe. The instrument may include a proximal end and a distal tip. The proximal end of the instrument may extend through the slot and may be configured to move along the slot to move the instrument from a proximal position to a distal position. In response to movement of the proximal end of the instrument from the proximal position to the distal position, the catheter may be advanced beyond the distal end of the housing into the catheter assembly and/or vasculature of a patient.

A blood sampling device useful for collecting a blood sample from a separate vascular access device is described herein. The blood sampling device includes a body shaped and sized for partial insertion into a separate vascular access device. The body includes a reservoir defined within the body, which has an internal volume sufficient to contain enough blood for use in a diagnostic blood test. The body also includes a gas permeable vent disposed on the body, in which the gas permeable vent is in gaseous communication with the reservoir. When connected to a separate vascular access device the blood sampling device collects a blood sample as blood flows into the reservoir from the separate vascular access device and as gases pass out the reservoir via the gas permeable vent.

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.
