A transfer device includes an introducer coupleable to a peripheral intravenous catheter, with the introducer having a proximal end portion and a distal end portion, a catheter having a proximal end portion and a distal end portion and defining a lumen, a secondary catheter having a proximal end portion and a distal end portion and defining a lumen, and an actuator receiving the proximal end portion of the catheter and the distal end portion of the secondary catheter. The actuator is moveable within introducer from a first position where the distal end portion of the catheter is positioned within the introducer to a second position where the distal end portion of the catheter is positioned outside of the introducer.

A cannula insertion system for inserting a cannula into a human or animal body, includes a cannula and a cannula insertion device to hold and insert the cannula into the human or animal body in an insertion direction. The cannula insertion system includes a safety device configured to retract the cannula or to release the cannula from the cannula insertion device when a force exerted on the cannula in a direction perpendicular to the insertion direction results in exceeding a respective safety threshold value.

A pressure based vessel locating system including a pressure based vessel locator device coupled to a needle or catheter. The pressure based vessel locator device can include a proximal end having an air permeable membrane, and a first chamber and a second chamber. The first chamber can be separated from a second chamber by an interior wall. Each of the first chamber and the second chamber include a proximal opening and a chamber opening having a pressure activated valve disposed therein. The pressure based vessel locator device can further include an air permeable membrane configured to cover proximal openings of the first chamber and the second chamber. Each of the chambers include a window enabling a user to observe the contents of each chamber. A method of identifying a blood vessel includes visually inspecting each chamber for the presence or absence of blood therein.

A test cartridge includes an adjustable lancet. The adjustable lancet is controlled by a controller. The adjustable lancet automatically detects a subject's finger, adjusts the lancet's height, pricks the finger to draw blood, moves a tube to collect the blood, moves the tube away from the finger, and empties the blood from the tube into a vial or receptacle. The adjustable lancet may include safety features to prevent the lancet to trigger when the subject's fingernail is facing the lancet, to control the amount that the lancet pierces the subject's finger, and/or to prevent the reuse of a test cartridge for multiple persons or multiple times by the same person. The adjustable lancet may include a massager wheel and/or a pressure bar to rub the subject's finger after the finger is pierced to facilitate drawing of the blood from the finger.

A portable medical storage unit (station) is configured in the form of a phlebotomy arm wedge that includes internal storage along with other optional features to facilitate a health professional to perform a phlebotomy. The portable medical storage unit thus provides an alternative product to a phlebotomy chair and has a much smaller footprint and can easily be stored in closet or the like. Moreover, the portable medical storage unit can be made at much less cost than a phlebotomy chair.

A cannula insertion system for inserting a cannula into a human or animal body, includes a cannula and a cannula insertion device to hold and insert the cannula into the human or animal body in an insertion direction. The cannula insertion system includes a safety device configured to retract the cannula or to release the cannula from the cannula insertion device when a force exerted on the cannula in a direction perpendicular

A needle guide assembly for inserting a needle into the body of a patient in order to access a subcutaneous target, such as a vessel, is disclosed. In one embodiment, the needle guide assembly comprises a needle guide body that is configured to at least indirectly and removably attach to an image producing device, such as an ultrasound probe. The needle guide body defines at least first and second elongate guide channels. Each guide channel defines a unique insertion angle with respect to a longitudinal axis of the ultrasound probe. Further, each guide channel is configured to accept needles of differing gauges. In other embodiments other needle guide assemblies are disclosed that include multiple guide channels for inserting a needle at a variety of insertion angles into the patient's body. Related methods are also disclosed. In yet other embodiments, needle guide assemblies including needle stop features are disclosed.

The present invention is directed to an automated vessel puncture device, methods of mapping three-dimensional views of subcutaneous vessels and methods for providing simultaneous real-time diagnostic assay.

A lancet driver is provided wherein the driver exerts a driving force on a lancet during a lancing cycle and is used on a tissue site. The driver comprises of a drive force generator for advancing the lancet along a path into the tissue site, and a manual switch for a user interface input.

A portable medical apparatus including at least a sampling assembly for providing at least one sample of a fluid in an object, a detector for determining at least one parameter of the fluid, an injector for performing at least one injection of an injection medium, and which are operable independent of each other for improved self-treatment of diseases such as diabetes. The portable medical apparatus has a single common housing for these components and a switch for changing between the sampling mode, the determining mode, and the injection mode. The apparatus also includes an actuator means for individually actuating the other components. The apparatus is an all-in-one device that facilitates the medical treatment process for patients, medical professionals or others.
