  • Patent number: 10485521
    Abstract: Provided herein is a method for sterilely filtering amniotic fluid from selected caesarean sections of an individual. The amniotic fluid is first centrifuged at 5,000 to 10,000 rpm for 30 to 60 minutes and filtered through filters with about 5 to about 10 ?m pore size. Next, the fluid is sequentially filtered through a series of membrane filters with the pore sizes 1 ?m and 0.45 or/and 0.2 ?m. The filtrate is then aseptically transferred to and sealed in syringes or vials. The fluid is subsequently lyophilized to obtain the lyophilisate of amniotic fluid. Amniotic fluid is reconstituted by adding sterile water to the lyophilisate, and the reconstituted fluid is used for wound healing, cosmetic, orthopedic or ophthalmic applications, particularly for the treatment of dry eyes.

  • Patent number: 10426694
    Abstract: Embodiments of the invention include a method and a device for increasing blood flow and controlling the temperature of a mammal by applying a desired pressure to extremities of a mammal. The device generally includes a pliant body element that is adapted to receive a portion of an extremity of the mammal therein, and then apply a pressure to a portion of the extremity when a pressure is provided to a region in which the extremity is positioned within the pliant body element. By evacuating the region in which the extremity is enclosed, a contact surface area between the extremity of a mammal and the pliant body element is increased, due to the external atmospheric pressure acting on the pliant body element against the skin of the extremity of the mammal. The application of pressure assures that sufficient contact and thermal heat transfer (heating or cooling) is provided to the extremity of the mammal.

  • Patent number: 7785292
    Abstract: The invention concerns an injection device with a housing adapted to receive a syringe having a discharge nozzle and a plunger. There is a trigger and a drive arranged to act upon the plunger on actuation of the trigger to advance the syringe from a retracted position to an extended position through an opening in the housing. A locking mechanism is arranged in and moveable relative to the housing. The locking mechanism is engaged with the plunger when the syringe is not in its extended position and disengaged from the plunger when the syringe is in its extended position. This means that movement of the plunger relative to the syringe is prevented when, in use, the syringe is advanced from a retracted position to an extended position. Hence the contents of the syringe are not expelled from the syringe during advancement from the retracted position to the extended position. The contents are only expelled when the syringe reaches the extended position.

  • Patent number: 7691084
    Abstract: Therapeutic devices that provide support or pressure to tissue. Devices contain a material that is capable of being contracted from its relaxed state to an evacuated state. The material applies pressure to the tissue of a patient when the material is in its relaxed state. Reduction of pressure by application of a vacuum results in a contracted state of the device, so that the device can be applied or delivered to a patient. Release of vacuum results in a return to the relaxed state, thus providing a maximum desirable pressure to tissue and avoiding the possibility of over-pressure which can result in tissue damage or necrosis.
