  • Patent number: 5055099
    Abstract: There is disclosed an autotransfusion system which essentially is contained in a unitary housing section which enables a practitioner to utilize the system in a rapid and efficient manner. The housing section has integrally associated therewith a blood reservoir, which is a major component of an autotransfusion system. The housing has secured thereto a set of instructions which are adapted to be mounted on the arm of an IV pole and which, when positioned on the arm of the IV pole, specifies vertical distances necessary to perform autotransfusion during a blood collection or blood distribution mode. The housing section, as containing the reservoir, with the package and instruction component, is used as a yardstick to establish specified distances in order to control pressure as afforded by gravity.

  • Patent number: 5045068
    Abstract: A flow rate regulator includes a first cylindrical member, a second cylindrical member and a disc-shaped member to regulate, the flow rate of liquid flowing through a transfusion unit. The liquid is introduced into the second cylindrical member via an inlet port. It flows through the disc-shaped member via a through hole and flows further along a peripherally extending groove in the first cylindrical member. Then, it is discharged from the first cylindrical member via an outlet port after the flow rate is regulated as required. The disc-shaped member is fitted in the second cylindrical member so as not to be rotated relative to the latter, and the sub-assembly is then fitted into the first cylindrical member. The peripherally extending groove is so designed that its cross-sectional area is gradually varied on the bottom portion of the first cylindrical member. The through hole in the disc-shaped member is communicated with the peripherally extending groove.

  • Patent number: 5041097
    Abstract: An intravenous catheter has an elongate small diameter flexible tubular front portion and a rear base portion which has an interior bore in communication with the interior of the tubular portion for connection to a needle or other fluid injection or withdrawal members. A thin flexible membrane seal formed of resilient stretchable material is secured over the opening at the rear of the catheter base. The elasticity of the membrane seal allows the beveled front end of a needle to be pushed through the membrane and puncture the seal as it passes through and will not tear, but will stretch as the forward motion of the needle continues and conform to the profile of front portion of the needle base and allow it to engage the interior of the catheter base. The needle may be inserted into the catheter in the usual manner and the needle and catheter may be used just as any standard catheter-needle assembly.

  • Patent number: 5006122
    Abstract: The transplantation of donor tissue into the brain is effected by locking the head relative to a stereotaxic unit; penetrating the brain with a first cannula to a predetermined depth to create a transplant site within the brain while the first cannula is fixed by the stereotaxic unit relative to the brain; then feeding a second cannula, which contains donor tissue at its distal end, through the already fixed first cannula so that the distal end of the second cannula comes to rest at the transplant site; and finally withdrawing the first cannula and the second cannula so as to leave the donor tissue at the transplant site.
