Abstract: Disclosed is an integrated lead frame pulse oximetry sensor which includes a thin metal lead frame (12) to which is connected light emitting diodes (16, 18) and a photodiode chip (20) for the purpose of emitting light and detecting light respectively. The thin metal frame (12) is deformable to attach to perfused tissue. The lead frame (12) has a very low mass which diminishes its susceptibility to motion induced artifact.

Abstract: A sensor assembly for a combination infusion fluid delivery system and blood chemistry analysis system includes a sensor assembly (40) with each of the assembly electrodes (46) monted in an electrode cavity (48) in the assembly. Each electrode cavity (48) includes a circular ridge (52) that defines a cylindrical inner cavity (54) and a ring-shaped outer cavity (56). The circular ridge (52) prevents the water soluble gel (60) from wicking into the surrounding selectively-permeable membrane (64), and thereby provides easier manufacture, higher yield rates, and longer shelf life. A helical groove (80) increases turbulence in the assembly, reducing the purge volume needed to flush the assembly (40) after each sample measurement. The system includes provision for delivering the infusion fluid and measuring blood chemistry during reinfusion of the blood at approximately the same flow rates.

Abstract: The present invention relates to a blood sampling sleeve which is intended for coaction with a blood sampling tube in which an internal subpressure prevails and which is sealed at one end thereof against the ingress of air and liquid by means of a sealing device that can be pierced or penetrated by a needle. The sampling sleeve is a one-piece structure intended for one-time-use only. The sleeve is also patient-friendly and is risk-free to the user, and can be handled quickly and easily. The sleeve includes an inner needle (16) which is intended to pierce the sealing device (14) fitted to the sampling tube (12), and an outer, conical standardized connector (22) which is intended for connection to a standard vein-puncturing needle. An inner channel (20) connects the connector orifice with the needle orifice and an inner valve (26) is provided in the channel (20). The valve (26) is closed when in a non-activated state and is intended to be opened automatically by the sealing device (14) of the sampling tube when the sealing device is penetrated by the needle (16).

Abstract: A blood-sampling device comprises a guide sleeve (10) and a tube (12) for receiving blood. The guide sleeve (10) is open at one end for insertion of the tube (12) and the other end carries a needle (14) whose tip points inwards. The end of the tube (12) inserted in the guide sleeve (10) has a membrane (16) which can be pierced by the needle (14). The tube (12) has a plunger (18) which can be pushed into the guide sleeve (10) until it rests against the membrane (16). The length of the needle (14) in the guide sleeve (10) is equal to the length of the stroke of the plunger (18) in the tube (12). A nonreturn valve (26) prevents the back-flow of blood.

Abstract: A self-sealing fluid collection tube (10) is provided with an elongated bore and a fluid entry end (14). A plug (16) of super-absorbent material is provided within the tube (10) opposite the fluid entry end (14). This plug is preferably vented (18) and is adapted to seal the tube (10) by expanding when contacted by a fluid, such as blood. After the fluid has been collected, the tube is placed in a pipetter-dispenser (50) in which a plunger (54), which is inserted into the tube (10), moves through a calibrated distance thereby advancing the plug (16) into the tube and expelling a selected volume of fluid from the tube (10). Alternatively, the fluid may be transferred into another receptacle by piercing the sealed plug (16) to form a new vent channel to permit drainage of the collected fluid into a receptacle.

Abstract: The blood collecting device of this invention comprises a blood collecting tube whose open end is sealed by a sealing member, a sticker needle having a needle tube consisting of a blood collecting needle part projecting to one direction and a hollow needle part projecting in the other direction and a flexible sheath covering the hollow needle part and a blood collecting tube holder as a hollow member whose rear end is open and to which the sticker needle is fitted. The blood collecting tube can be inserted into the blood collecting tube holder without substantially coming into contact with the inner surface of the latter. Furthermore, the blood collecting tube holder and the blood collecting tube are provided with a pair of anchor means meshing with each other while the sealing member of the blood collecting tube inserted into the blood collecting tube holder is being stuck by the hollow needle and having anchor force exceeding the repulsive force of the flexible sheath when the sheath is compressed by the sealing member of the blood collecting tube in the axial direction. Thus, the blood collecting tube can be inserted easily into the blood collecting tube holder and fall-off of the blood collecting tube due to the repulsive force of the flexible sheath can be prevented because the anchor means of the blood collecting tube meshes with that of the blood collecting tube holder after insertion.

Abstract: When collecting blood samples in sealed systems evacuated specimen vials (6) are used, which with a foremost penetratable cap are inserted into a holder (4) to which a sampling needle (2, 10) is secured; the rear end of the needle extends into the holder and perforates the cap (46) of the specimen vial, thus enabling blood collection through a thin needle by the suction effect from the vial. There is an element of risk attached to using needles with a two-sided protruding needle, and with the invention the extraction needle (10) is only one-sidedly protruding from its holding piece (8), whilst in return the holder (4) is made with a built-in, completely screened needle portion (22) for connection with the vial (6). Special sealing problems at the changing of specimen vials in the same extraction procedure is countered in that the needle portion (22) is displaceably secured in the holder (4, 26) and constitutes part of a valve arrangement (26, 28, 34), which is opened by the insertion of the needle portion (22) at the insertion of the vial (6) and is closed at the removal of the vial. Furthermore an advantageous design of the vial (6) is disclosed.
