A device (302) for sampling and / or analyzing blood or other body fluid of a subject. A housing (306) contains a plurality of lancets (308) and optionally includes test elements (324) to take up a sample of blood, an evaluation system and a display. A complete system that can be handled as a single device, for example in the form of a wristwatch, includes a multiplicity of test elements (324) and lancets (308), which can be brought successively to a working position to perform multiple measurements. A cassette or carrier (320) includes multiple lancets (308) and / or test elements (324), for insertion into the device.

The invention relates to an analysis appliance for analysis of blood samples, and to a user identification method integrated in the analysis appliance. The analysis appliance comprises a sampling device for taking blood samples, and an analysis device. A delivery device is also provided for transferring the blood samples from the sampling device to the analysis device, wherein the operating parameters concerning sampling, transfer of the sample to the analysis device, and analysis of the sample, can be adapted to the respective user. The operating parameters can be adapted by automatic, spontaneous execution of an automatically determined number of test measurements.

Novel devices which can be used to both collect blood samples from and administer medical fluids to a patient on a repeated and continual basis using one rather than multiple needle insertions. The device typically includes a main tubing segment confluently connected to a cannula for insertion in the patient's vein. A syringe port and a volumeter for collecting blood branch separately from the main tubing segment. The device is used to collect blood by attaching an empty blood collection syringe to the syringe port, inserting the cannula in the patient's vein, allowing passive flow of blood from the main tubing segment into the volumeter under intrinsic venous blood pressure and capillary action, and then facilitating active flow of blood from the volumeter into the blood collection syringe by extending the syringe plunger. The device may be used to administer medical fluids to the patient through the main tubing segment from a medical fluid syringe or catheter attached to the syringe port.

A disposable, closed fluid sampling system for use with a medical conduit line (70), especially for taking blood samples from a pressure monitoring line. The conduit line (70) has at least one fluid sampling site (100, 102) interposed between a distal segment of tubing and a proximal segment of tubing. The system includes a disposable subsystem (96) having a bypass cannula (110) adapted to engage the sampling site, a reservoir (112) for drawing a prime volume of fluid past the sampling site, and a fluid sampling container (114). A 3-way stopcock (116) may connect the reservoir, bypass cannula, and sampling vessel for controlling the sampling procedure. The bypass cannula (110) may simultaneously place the subsystem into fluid communication with an inner chamber (136) of the sampling site and exclude the proximal segment of the conduit line. Alternatively, a stopcock immediately adjacent the sampling site in the proximal segment may be utilized. A method of using the system includes attaching the disposable subsystem, opening the reservoir to the distal segment while excluding the proximal segment, drawing a prime volume of fluid into the reservoir, opening the sampling vessel to the distal segment and drawing a sample, re-infusing the prime volume into the distal segment, and removing and discarding the subsystem. The reservoir remains attached between the prime volume draw and re-infusion and is thus 'closed'.

Plastic test tube for taking blood samples, comprising a hollow tubular body and an adhesive protective film able to adhere to the tubular body. The tubular body is made of polyethylene terephthalate and has: a tubular wall which delimits a working volume and defines an outer surface; an open mouth for insertion of liquids at a first end of the wall; and a bottom for closing a second end of the wall. The adhesive protective film is able to adhere to the wall of the tubular body over at least a portion of the outer surface. The test tube is characterized in that the wall of the tubular body has a thickness in the range of 1 to 3 mm and in that the protective film is defined by a layer of polypropylene, polyethylene or copolymers thereof. The layer has a thickness in the range of between 40 and 60 μm and is able to form a liquid barrier.

The invention relates to a lancing device (1) for taking blood samples. The device comprises a housing (2), an axially displaceable lancet holder element (32) for holding a lancet (12), a driving unit (30) including at least one piercing spring element (31) and used for driving the axially displaceable lancet holder element (32), and a tension carrying element (26) that can be fixed to a tension position (36) and is used for tensioning the piercing spring element (31). According to the invention, the fixable tension carrying element (26) is temporarily and axially fixed to the tension position (36) via a lock device (35) that can be locked to the axially displaceable lancet holder element (32).

The invention concerns a process for the production of cylindrical holders for vacuum test tubes and the holders obtained therefrom. The process includes the insertion of the straight needle into the moulded holder and the subsequent bending of the needle, so that its outer end adheres to the edge of the casing, thus facilitating the insertion of the needle into the vein. The new disposable holder is particularly useful for said blood sampling, as it guarantees the alignment of the needle with respect to the vein.
