Platelet-rich plasma separator and platelet-rich plasma separation method

摘要

Provided is a platelet-rich plasma separator which can carry out the separation of a platelet-rich plasma with a small number of gamma radiation sterilized instruments and a platelet-rich plasma separation method. The platelet-rich plasma separator comprises a first syringe and a second syringe. The first syringe comprises a first syringe cylinder provided with a first port on which a blood collection needle can be mounted, a first cap detachable from the first port, a first gasket for sealing the first syringe cylinder fluid-tightly, which first gasket is reciprocated within the first syringe cylinder, and a first plunger provided detachably on the first gasket. The second syringe comprises a first hollow needle, which can be passed through the first gasket, a second syringe cylinder having a second port on which the first hollow needle can be mounted, a second cap detachable from the second port, a second gasket for sealing the second syringe cylinder liquid-tightly, which second gasket is reciprocated within the second syringe cylinder, and a second plunger provided detachable on the second gasket.

主权项

1. A platelet-rich plasma separator comprising a first syringe used to aspirate blood and a second syringe used to aspirate a centrifuged section containing platelets and plasma from the first syringe,
wherein said first syringe comprises:
a first syringe cylinder having a first port on which a blood collection needle can be mounted,a first cap detachable from said first port,a first gasket for sealing said first syringe cylinder liquid-tightly, which first gasket is reciprocated within the first syringe cylinder, anda first plunger provided detachably on said first gasket, wherein the first gasket has a mounting opening for removably mounting the first plunger, said mounting opening extending into the first gasket without extending through the first gasket; and wherein said second syringe comprises:
a first hollow needle, which can be passed through said first gasket,a second syringe cylinder having a second port on which said first hollow needle can be mounted,a second cap detachable from said second port,a second gasket for sealing said second syringe cylinder liquid-tightly, which second gasket is reciprocated within the second syringe cylinder;a second plunger provided detachably on said second gasket, anda guide piece formed on the second syringe cylinder around the second port and extending beyond the distal tip of the second port and into said mounting opening of said first syringe, the guide piece having a diameter allowing the guide piece to fit into the mounting opening.
