A blood collection apparatus is provided with a blood collection assembly including a casing tube including a forward nose, a plurality of connectors and a rear flange having a flexible projection, a plunger slidably disposed in the casing tube and including a forward plug and an elongated arm having a plurality of cavities, a blood collection tubes, an adapter assemblies each including a tube body, a first tube extending out of one end and insert into a related connectors of the casing tube, a second tube extending out of the end to insert into one of the blood collection tubes, and a butterfly needle assembly mounted to the nose of the casing tube. A pulling of the plunger moves the plug rearward and pivots the projection to engage in one cavity of the elongated arm and an orifice of the each related connectors is not blocked by the plug so as to flow blood from the tube casing to one of the blood collection tube via one connector and one adapter assembly.

It is an object of this disclosure to facilitate a series of puncture-related operations in a puncture instrument. In a main case of a puncture instrument, a main rod is provided. An injector rod is mounted to a main rod and includes a lancet holder on one end side. An actuating rod is mounted to the injector rod and has an engagement component on the other end side. A first biasing member biases the injector rod toward the first end side. A manipulation component is provided so as to be slidable in and out through an opening on the other end side of the main case. A locking member is axially supported rotatably by a portion of the main rod between the manipulation component and the injector rod. The locking member includes a first engaged part, a second engaged part and a second biasing member.

A device and method for the collection of blood from an umbilical cord. Unlike other devices traditionally used which make use of a needle for insertion through the cord tissue and into the umbilical vein, the present device includes a long probe to be inserted into the umbilical vein after the umbilical cord is cut. The device additionally includes a fastening component to be tied around the umbilical cord under the position of the head of the device once inserted to fasten it in place. The device has a wide aperture for faster flow of the blood at a constantly tapered angle to reduce shear forces that may damage cells. Additionally, the head of the device is angled for easy insertion into the umbilical vein and is ribbed to resist falling out of the vein.

The invention relates to a blocking mechanism for a skin incision device and to a method of controlling of a skin incision device by a blocking mechanism. The blocking mechanism comprises a blocking means and a trigger means, which by, respectively, a fixing means and a locating means are mounted in a housing of the cooperating incision device, and which are provided with an engaging means configured to cooperate mutually with each other so that an inadvertent firing of the blocking mechanism and an inadvertent actuation of the incision device prior to use of the device as well as a re-use of the device is not possible, and an indication of a state of use of the device by the blocking means and the trigger means is unambiguous.

The present invention relates to an apparatus for sample taking from a fluid-conducting system, wherein the apparatus has at least one adapter which comprises at least one septum and at least one cannula displaceable relative to the septum, wherein the cannula is displaceable such that it penetrates the septum in a sample taking position and does not penetrate the septum in a flushing position; and wherein the adapter has at least one flushing region for a flushing medium which is arranged such that it is in fluid communication with the inner space of the cannula in the flushing position of the cannula; and wherein the apparatus has at least one receiving region having locking means for the fluid-conducting system by which the fluid-conducting system is fixable in a defined position relative to the adapter. The present invention furthermore relates to a blood treatment device and to a method for taking a sample from a fluid-conducting system.
