Patent number: 8333711Abstract: The invention relates to a blood taking device (1), in particular, for newborn babies and small children or small animals, comprising a blood taking vessel (2), provided on the front end thereof with a cannula (5) with a sharpened tip (4), whereby a porous, gas-permeable limiting element (8) which automatically stops the flow of taken blood, is arranged by pressing in the blood taking vessel (2) in a defined position. The rear end of the blood taking vessel (2) is sealed by a plug (11) which may be temporarily opened for taking blood (11), which dispenses the taken blood by means of a stroke running in a sealed manner in the blood taking vessel (2), which empties under pressure at least a part amount of the blood retained before the limiting element (8).Type: GrantFiled: April 21, 2005Date of Patent: December 18, 2012Assignee: Sarstedt AG & Co.Inventor: Walter Sarstedt

Patent number: 7303545Abstract: A butterfly-needle set has an elongated two-part case forming a pair of transversely open slots. An elongated needle in the case has a pair of generally coplanar and oppositely projecting wings projecting out of the case through the slots. The slots are sufficiently long that the needle can move longitudinally between a front position with the needle projecting from a front end of the case and a rear position with the needle completely within the case. An elastically deflectable spring element projects at a small acute angle toward a rear end of the case into at least one of the slots so as to deflect elastically and allow the needle to move from the front position into the rear position and to block movement of the needle from the rear position into the front position.Type: GrantFiled: November 20, 2002Date of Patent: December 4, 2007Assignee: Sarstedt AG & Co.Inventor: Walter Sarstedt

Patent number: 7294111Abstract: A blood-drawing device has a specimen tube having a projecting tip having an outer connection region of a predetermined diameter and a guide sleeve fittable over the tip and having an inner resilient part. The inner resilient part has an inside diameter smaller than the diameter of the connection region. A needle fitted to the guide sleeve is surrounded by an elastomeric tubular needle shield inward from the guide sleeve. The sleeve can move between an outer position with the needle shield extending inward past the inner needle end and the resilient part offset outward from the connection region and an inner position with the needle end in the specimen tube, the needle shield compressed between the sleeve and the specimen tube, and the resilient part fitting tightly around the connection region and deformed outwardly thereby such that the resilient part grips the connection region.Type: GrantFiled: December 16, 2002Date of Patent: November 13, 2007Assignee: Sarstedt AG & Co.Inventor: Walter Sarstedt

Publication number: 20050043650Abstract: The invention relates to a device for accommodating body fluids, comprising a small tube (1) that, at its front end, supports a dome (10) having a pierceable stopper for a guide sleeve (2), which can be pushed onto the dome (10) and which, on the side facing the dome, has a cannula (5) with a valve rubber (3) and, on the side facing away from the dome, has a connecting piece or the front part of a double cannula. The guide sleeve (2) is made of a rigid material and is provided, at its front end located outside of a grip area (8) provided for normal handling, with a flexible section (6). The dome (10) comprises, in a connecting area, a diameter that is greater than the inside diameter of the guide sleeve (2), whereby when the device is assembled for use, the larger dome diameter widens the flexible section (6) that surrounds the connecting area of the dome (10) in a non-positive manner in order to obtain a retention force.Type: ApplicationFiled: December 16, 2002Publication date: February 24, 2005Inventor: Walter Sarstedt

Publication number: 20050038398Abstract: The invention relates to a protective housing (1) for a butterfly needle (2), which comprises an elongate lower cap (4) and an elongate upper cap (3), each having a substantially U-shaped cross-section, that can be closed to give a housing unit once the wings of the butterfly needle (2) are inserted. Guide grooves (9) are defined by free gap distance on both sides between the adjacent vertical side walls (6, 7) of the caps (3, 4). An upstream spring-loaded element (17) projects in a constant locking position (II) from at least one of the side walls (6 or 7) into one of the guide grooves (9).Type: ApplicationFiled: November 20, 2002Publication date: February 17, 2005Inventor: Walter Sarstedt

Patent number: 6824741Abstract: A device for carrying out a test for the detection of particles in urine, especially for carrying out a test to determine the susceptibility of a test subject for kidney stones, whereby urine from the test subject is taken and collected and then the detection test is carried out, whereby the urine after a stand time is poured out of the test vessel, whereby the residue of test particles may be present in the test vessel is detected subsequently by the addition of a detection reagent, especially a dye reagent for optical detection, especially for a self test by a test subject, for example, at home. The device having a collecting vessel in which the urine is directly collected from the test subject and which also simultaneously forms the test vessel. The test vessel is column shaped and tapered toward its bottom and upwardly transitions into an overflow region.Type: GrantFiled: September 13, 2002Date of Patent: November 30, 2004Assignee: Starstedt AG & Co.Inventors: Walter Sarstedt, Dagmar Flach, Horst Färber, Petra Gross

Publication number: 20040215107Abstract: A blood collection device has a holder having a forwardly extending sharp-edged cannula capable of venipuncture and a rearwardly extending cannula. A guide sleeve into which a blood-collection tube is insertable from one end, at an opposite end, threadedly receives the holder whereby the tube can be filled with blood conducted by the rearwardly extending cannula into the device. A closed end elastic tubular valve rubber sheath surrounding and hugging the rearwardly extending cannula is shape locked and force fitted in said guide sleeve.Type: ApplicationFiled: January 29, 2004Publication date: October 28, 2004Applicant: SARSTEDT AG & Co.Inventors: Walter Sarstedt, Horst Farber

Patent number: 6672345Abstract: A tube holding a sample of blood and having an end provided with a pierceable closure is partially evacuated of gas by an apparatus that has a stationary guide defining an axis inclined at an angle to the horizontal. A needle fixed in the guide projects axially downward therein. A slide in the guide forms a downwardly inclined and open seat centered on the axis and adapted to receive the end of the tube. The slide is movable in the guide between an outer position with the seat spaced past an end of the needle and an inner use position with the needle projecting into the seat so that in the use position the needle projects through the closure of the tube fitted to the seat. The slide is urged axially downward in the guide, and a pump is provided for aspirating air through the needle.Type: GrantFiled: October 2, 2002Date of Patent: January 6, 2004Assignee: Sarstedt AGInventor: Walter Sarstedt
